Description

本発明は、車両用シガーライタープラグに関し、特に、ノブを含む各部品の構造を単純化して組立工程を減らして製造原価及び製品の重量を抑える一方、強制的に嵌め込む方式の採用により、発熱体の支持円筒の上部に結合されたノブの遊動を防ぎ、内側カバーが外側カバー内で上下に移動する際に、内側カバーが外側カバーから離脱しないように押さえるようにする車両用シガーライタープラグに関する。   The present invention relates to a cigarette lighter plug for a vehicle, and in particular, simplifies the structure of each part including a knob to reduce the assembly process to reduce the manufacturing cost and the weight of the product, while adopting a method of forcibly fitting, thereby generating heat. The present invention relates to a cigarette lighter plug for a vehicle that prevents loosening of a knob coupled to the upper part of a body support cylinder and prevents the inner cover from being detached from the outer cover when the inner cover moves up and down in the outer cover. .

通常、車両用シガーライターはシガーライターソケットと一対をなすものであって、シガーライターソケットとともに運転者や同乗者が喫煙することができるように車両の前面パネルや座席列の間に設けられる（特許文献１参照）。   Normally, a cigarette lighter for a vehicle is paired with a cigarette lighter socket, and is provided between a front panel of a vehicle and a seat row so that a driver and a passenger can smoke together with the cigarette lighter socket (patent) Reference 1).

車両用シガーライターは、バッテリー電源と連結した状態で車体に内蔵されたシガーライターソケットと、使用者が手に持ってタバコに火を付けるシガーライタープラグからなる。ソケットは、車両のバッテリーから印加される電流を利用することができるように、バッテリーに電気的に連結された二つの端子を有し、プラグはバッテリーの電流によってタバコに火を付けるように発熱体を有する。車両用シガーライターは、バイメタル部材とスプリングの弾性力を利用して発熱体が一定の温度に到達すると、プラグが挿入状態から解除されるとともに、電源が遮断される。   A cigarette lighter for a vehicle includes a cigarette lighter socket built in the vehicle body in a state of being connected to a battery power source, and a cigarette lighter plug that a user holds in his hand to ignite a cigarette. The socket has two terminals electrically connected to the battery so that the current applied from the battery of the vehicle can be utilized, and the plug is a heating element to ignite the cigarette by the battery current. Have When the heating element reaches a certain temperature using the bimetal member and the elastic force of the spring, the vehicle cigarette lighter is released from the inserted state and the power is shut off.

上記のような構成を有するシガーライタープラグは、部品数が多くて製造原価が高く、組立工程が複雑で重さが嵩む。これに従来には外部本体すなわち、ケースとノブを強制的に嵌め込む方式により結合し、残りの部品はリベッティング方式により一体型で結合する技術が開発されたが、これはシガーライタープラグを製造する過程において、ねじやボルトなどのような締結手段を利用しなくても良い。   The cigarette lighter plug having the above-described configuration has a large number of parts, a high manufacturing cost, a complicated assembly process, and a heavy weight. Conventionally, a technology has been developed in which the external body, that is, the case and the knob are forcibly fitted together, and the remaining parts are joined together by the riveting method, but this produces a cigarette lighter plug. In the process, fastening means such as screws and bolts may not be used.

しかし、強制的に嵌め込む方式によりケースとノブを一体型で結合する場合、ノブがケースに密着せず、ノブの遊動が発生する問題点がある。   However, when the case and the knob are integrally coupled by a method of forcibly fitting, there is a problem that the knob does not come into close contact with the case and the knob is loosely moved.

また、発熱体の支持円筒(15)はノブ(11)と一体型で結合されるが、ノブ(11)の下端部に位置した結合部材(22)には、発熱体の支持円筒(15)の嵌合突起(21)との結合のための嵌合凹溝(23)が形成されているので、発熱体の支持円筒(15)の上端部に結合されたノブ(11)が発熱体の支持円筒(15)から分離しない。   Further, the heating element support cylinder (15) is integrally coupled to the knob (11), but the coupling member (22) located at the lower end of the knob (11) is connected to the heating element support cylinder (15). Since the fitting groove (23) for coupling with the fitting projection (21) is formed, the knob (11) coupled to the upper end of the support cylinder (15) of the heating element Do not separate from the support cylinder (15).

特に、ノブ(11)の結合部材(22)が弾性を有しているので、ノブ(11)の結合部材(22)を発熱体の支持円筒(15)の内部に挿入し始める時は、結合部材(22)が内側に捩れて結合部材(22)の嵌合凹溝(23)に発熱体の支持円筒(15)の嵌合突起(21)が入ると、結合部材(22)が元の状態に広がりながらノブ(11)が発熱体の支持円筒(15)から分離しない。   Particularly, since the coupling member (22) of the knob (11) has elasticity, when the coupling member (22) of the knob (11) starts to be inserted into the support cylinder (15) of the heating element, the coupling member (22) When the fitting projection (21) of the support cylinder (15) of the heating element enters the fitting groove (23) of the coupling member (22) when the member (22) is twisted inward, the coupling member (22) is restored to its original position. The knob (11) does not separate from the support cylinder (15) of the heating element while spreading in the state.

この場合、発熱体の支持円筒(15)の内周面にノブ(11)の結合部材(22)の外周面が密着せず、結合部材(22)の嵌合凹溝(23)に発熱体の支持円筒(15)の嵌合突起(21)が完全に密着しないので、発熱体の支持円筒(15)に結合されたノブ(11)の遊動が発生することがあるが、本発明はこれを防ぐために、発熱体の支持円筒(15)にノブ(11)の結合部材(22)を強制的に嵌め込む方式により結合してノブ(11)の遊動を防ぐ。   In this case, the outer peripheral surface of the coupling member (22) of the knob (11) is not in close contact with the inner peripheral surface of the support cylinder (15) of the heating element, and the heating element is inserted into the fitting groove (23) of the coupling member (22). Since the fitting protrusion (21) of the support cylinder (15) is not completely in close contact, the knob (11) coupled to the support cylinder (15) of the heating element may be loosened. In order to prevent this, the coupling member (22) of the knob (11) is forcibly fitted into the support cylinder (15) of the heating element to prevent loosening of the knob (11).

このために、ノブ(11)すなわち、ノブ(11)の結合部材(22)の外周面に多数のリブ(24)を形成し、発熱体の支持円筒(15)にノブ(11)の結合部材(22)を強制的に嵌め込む方式により結合した時、ノブ(11)の外周面のリブ(24)が発熱体の支持円筒(15)の内周面に密着することで、ノブ(11)の遊動を防ぐことができる。   For this purpose, a large number of ribs (24) are formed on the outer peripheral surface of the knob (11), that is, the coupling member (22) of the knob (11), and the coupling member of the knob (11) is formed on the support cylinder (15) of the heating element. When the (22) is forcibly fitted, the rib (24) on the outer peripheral surface of the knob (11) is in close contact with the inner peripheral surface of the support cylinder (15) of the heating element, so that the knob (11) Can be prevented.

ここで、ノブ(11)の結合部材(22)の外周面に形成されるリブ(24)は４ないし８個程度で一定の間隔を介して配置され、発熱体の支持円筒(15)に結合される方向に沿って形成され、発熱体の支持円筒(15)と最初に接する端部から上方へ行くほど漸進的に高さが高くなることが望ましい。   Here, about 4 to 8 ribs (24) formed on the outer peripheral surface of the coupling member (22) of the knob (11) are arranged at regular intervals and coupled to the support cylinder (15) of the heating element. It is desirable that the height gradually increases as it goes upward from the end portion that is formed along the direction in which it is formed and first contacts the support cylinder (15) of the heating element.

勿論、ノブ(11)の結合部材(22)の嵌合凹溝(23)に、嵌合凹溝(23)の外径よりも小さな内径を有する発熱体の支持円筒(15)の嵌合突起(21)が結合されているので、外部衝撃にもかかわらずノブ(11)が発熱体の支持円筒(15)から離脱しないことは当然である。   Of course, the fitting protrusion of the support cylinder (15) of the heating element having an inner diameter smaller than the outer diameter of the fitting groove (23) is formed in the fitting groove (23) of the coupling member (22) of the knob (11). Since (21) is coupled, it is natural that the knob (11) does not detach from the support cylinder (15) of the heating element in spite of external impact.

ノブ(11)の内部は中空であり、結合部材(22)がある端部の外縁に沿って発熱体の支持円筒(15)のスプリング接触片(28)及びスプリング(19)の端部と接するようにフランジ形態のストッパ(25)が形成される。ノブ(11)は電気が通じないプラスチック材質によって射出成形されるものであって、一回の成形によってストッパ(25)と嵌合凹溝(23)とリブ(24)を有する結合部材(22)まで全て形成されるので、従来のように各々の部品を別個に成形して組立てる必要がない。   The inside of the knob (11) is hollow and contacts the spring contact piece (28) of the support cylinder (15) of the heating element and the end of the spring (19) along the outer edge of the end where the coupling member (22) is located. Thus, a flange-shaped stopper (25) is formed. The knob (11) is injection-molded by a plastic material that does not conduct electricity, and is a coupling member (22) having a stopper (25), a fitting groove (23), and a rib (24) by a single molding. Therefore, it is not necessary to separately mold and assemble each part as in the prior art.

発熱体の支持円筒(15)を覆う中空形態のカバーは、内側カバー(14)と外側カバー(26)からなる。内側カバー(14)の一部は発熱体の支持円筒(15)と当接し、ノブ(11)を引っ張ると発熱体の支持円筒(15)の発熱体ケース(16)が内側カバー(14)の端部を押して外側カバー(26)とともに抜け出るようになる。内側カバー(14)の中間部分は直角に曲折してスプリング係止顎部(27)を形成する。外側カバー(26)は内側カバー(14)と結合され、発熱体ケース(16)がソケット内のバイメタルに捕獲されない状態では発熱体ケース(16)が外側カバー(26)の内部に位置するように構成される。   A hollow cover that covers the support cylinder (15) of the heating element includes an inner cover (14) and an outer cover (26). Part of the inner cover (14) abuts the support cylinder (15) of the heating element, and when the knob (11) is pulled, the heating element case (16) of the support cylinder (15) of the heating element is attached to the inner cover (14). Push the end to come out with the outer cover (26). A middle portion of the inner cover (14) is bent at a right angle to form a spring locking jaw (27). The outer cover (26) is coupled with the inner cover (14) so that the heating element case (16) is positioned inside the outer cover (26) when the heating element case (16) is not captured by the bimetal in the socket. Composed.

一方、スプリング(19)は、ノブ(11)のストッパ(25)と内側カバー(14)のスプリング係止顎部(27)との間に挟入された状態で内側カバー(14)と発熱体の支持円筒(15)との間の空間に位置するようになる。   On the other hand, the spring (19) is sandwiched between the stopper (25) of the knob (11) and the spring locking jaw (27) of the inner cover (14), and the inner cover (14) and the heating element. It comes to be located in the space between the support cylinders (15).

この時、スプリング(19)は、発熱体の支持円筒(15)と内側カバー(14)を電気的に連結する役目もするが、スプリング(19)が発熱体の支持円筒(15)と電気的に接触されない場合を避けるため、発熱体の支持円筒(15)の上端部に多数のスプリング接触片(28)が延在して外側に曲折している。   At this time, the spring (19) also serves to electrically connect the support cylinder (15) of the heating element and the inner cover (14), but the spring (19) is electrically connected to the support cylinder (15) of the heating element. In order to avoid the case where they are not in contact with each other, a large number of spring contact pieces (28) extend at the upper end of the support cylinder (15) of the heating element and are bent outward.

また、内側カバー(14)は交互に一定の間隔を介して配置された多数の弾性支持片(13)と、多数の係止溝(12)を有する。弾性支持片(13)は内側カバー(14)の一部が‘Ｕ'字状に切成されたものであって、該弾性支持片(13)は内側カバー(14)が外側カバー(26)内で上下に移動する時、内側カバー(14)と外側カバー(26)の摩擦力を最小化しながらも、内側カバー(14)が外側カバー(26)内で遊動しないように押さえる。また、弾性支持片(13)はノブ(11)とともに下に下がった発熱体の支持円筒(15)が原状復帰する時、外側カバー(26)と内側カバー(14)との間に摩擦力を発生させ、内側カバー(14)が発熱体の支持円筒(15)とともに上昇しないように押さえる。   The inner cover (14) has a large number of elastic support pieces (13) and a large number of locking grooves (12) that are alternately arranged at a constant interval. The elastic support piece (13) is formed by cutting a part of the inner cover (14) into a 'U' shape, and the elastic support piece (13) is formed by the inner cover (14) being the outer cover (26). When moving up and down, the inner cover (14) is pressed against the outer cover (26) while minimizing the frictional force between the inner cover (14) and the outer cover (26). In addition, the elastic support piece (13) generates a frictional force between the outer cover (26) and the inner cover (14) when the support cylinder (15) of the heating element lowered with the knob (11) returns to its original state. The inner cover (14) is pressed so as not to rise together with the support cylinder (15) of the heating element.

内側カバー(14)の係止溝(12)は、外側カバー(26)の係止突起(30)と一対をなすものであって、係止溝(12)と係止突起(30)は外側カバー(26)内で上下に移動する内側カバー(14)が外側カバー(26)から離脱されないながらも一定の距離分上下に移動するように移動距離を制限する。   The locking groove (12) of the inner cover (14) is paired with the locking protrusion (30) of the outer cover (26), and the locking groove (12) and the locking protrusion (30) are outside. The moving distance is limited so that the inner cover (14) moving up and down in the cover (26) moves up and down by a certain distance while not being detached from the outer cover (26).

すなわち、内側カバー(14)の係止溝(12)は図４及び図５のように、外側カバー(26)の係止突起(30)が係止溝(12)の最上端に位置した時には、発熱体の支持円筒(15)の発熱体ケース(16)がソケット(17)のバイメタル部材(29)と結合可能な位置を維持し、外側カバー(26)の係止突起(30)が係止溝(12)の最下端に位置した時には、発熱体の支持円筒(15)の発熱体ケース(16)がソケット(17)のバイメタル部材(29)から完全に分離した状態を維持することができる程度の上下幅を有する。   That is, the locking groove (12) of the inner cover (14) is located when the locking protrusion (30) of the outer cover (26) is positioned at the uppermost end of the locking groove (12) as shown in FIGS. The heating element case (16) of the supporting cylinder (15) of the heating element maintains a position where the heating element case (16) can be coupled with the bimetal member (29) of the socket (17), and the locking protrusion (30) of the outer cover (26) is engaged. When located at the lowermost end of the stop groove (12), the heating element case (16) of the supporting cylinder (15) of the heating element can be kept completely separated from the bimetal member (29) of the socket (17). It has a vertical width as much as possible.

特に、内側カバー(14)の係止溝(12)と外側カバー(26)の係止突起(30)の結合は、図５及び図６のように、ソケット(17)のバイメタル部材(29)に結合された発熱体ケース(16)が発熱体(18)の発熱でバイメタル部材(29)から離脱される時、発熱体(18)と発熱体ケース(16)、発熱体の支持円筒(15)そしてノブ(11)の移動距離を制限して発熱体(18)と発熱体ケース(16)がソケット(17)のバイメタル部材(29)から機械的及び電気的に完全に分離するだけに過ぎず、ソケット(17)から完全に飛び出さない。   In particular, the coupling of the latching groove (12) of the inner cover (14) and the latching protrusion (30) of the outer cover (26) is performed as shown in FIGS. 5 and 6 by the bimetal member (29) of the socket (17). When the heating element case (16) coupled to the heating element (18) is detached from the bimetal member (29) due to the heat generated by the heating element (18), the heating element (18), the heating element case (16), and the supporting cylinder (15 ) And the movement distance of the knob (11) is limited so that the heating element (18) and the heating element case (16) are completely separated mechanically and electrically from the bimetal member (29) of the socket (17). Without popping out of the socket (17) completely.

上記の本発明の一実施例とともに本発明による他の実施例の車両用シガーライタープラグについて、図６ないし図８を参照して説明する。   A vehicle cigarette lighter plug according to another embodiment of the present invention together with the above-described embodiment of the present invention will be described with reference to FIGS.

発熱体(41)が発熱体ケース(40)の内部にねじで固定結合され、発熱体ケース(40)の外周面はシガーライターソケット内のバイメタル部材の内側に捕獲可能な形態をなす。   The heating element (41) is fixedly coupled to the inside of the heating element case (40) with a screw, and the outer peripheral surface of the heating element case (40) has a form that can be captured inside the bimetal member in the cigarette lighter socket.

発熱体の支持円筒(37)は通電可能な金属で製作され、その内部が中空であり、一方の端部は開放されており、開放面側に近い側面の三箇所には矩形の嵌合溝(38)が形成される。発熱体(41)と発熱体の支持円筒(37)との間には絶縁物質が挿入されるが、発熱体(41)と発熱体の支持円筒(37)とねじで連結されて発熱体(41)と発熱体ケース(40)、発熱体の支持円筒(37)との間には互いに通電可能である。   The support cylinder (37) of the heating element is made of a metal that can be energized, the inside is hollow, one end is open, and there are rectangular fitting grooves at three locations on the side close to the open surface side. (38) is formed. An insulating material is inserted between the heating element (41) and the support cylinder (37) of the heating element, but is connected to the heating element (41) and the support cylinder (37) of the heating element with a screw. 41), the heating element case (40), and the supporting cylinder (37) of the heating element can be energized with each other.

発熱体の支持円筒(37)はノブ(31)と結合されるが、ノブ(31)の端部に形成された結合部材(32)の嵌合突起(43)が発熱体の支持円筒(37)の嵌合溝(38)に係止することで結合される。ノブ(31)の結合部材(32)が弾性を有しているので、ノブ(31)の端部を発熱体の支持円筒(37)の内部に挿入し始める時は結合部材(32)が内側に曲折し、結合部材(32)の嵌合突起(43)が発熱体の支持円筒(37)の嵌合溝(38)に入ると結合部材(32)が元の状態に広がるようになる。図８は結合部材(32)があるノブ(31)の端部を下側から見たものであって、発熱体の支持円筒(37)の内面に密着するように挿入される端部全体のうち三箇所だけが他の部分より狭幅を有するように分離され、嵌合突起(43)が外側に形成されることで結合部材(32)になる。   The support cylinder (37) of the heating element is coupled to the knob (31), but the fitting protrusion (43) of the coupling member (32) formed at the end of the knob (31) has a support cylinder (37) of the heating element. ) Are engaged with each other by engaging with the fitting groove (38). Since the coupling member (32) of the knob (31) has elasticity, when the end of the knob (31) starts to be inserted into the support cylinder (37) of the heating element, the coupling member (32) When the fitting protrusion (43) of the coupling member (32) enters the fitting groove (38) of the support cylinder (37) of the heating element, the coupling member (32) expands to its original state. FIG. 8 shows the end of the knob (31) with the coupling member (32) as viewed from the lower side, and shows the entire end inserted so as to be in close contact with the inner surface of the support cylinder (37) of the heating element. Only three of them are separated so as to have a narrower width than the other parts, and the fitting protrusion (43) is formed on the outer side to form the coupling member (32).

ノブ(31)の内部は中空であり、結合部材(32)がある端部の外端に沿ってはスプリング(42)の端部と接するようにフランジ形態のストッパ(33)が形成される。ノブ(31)はプラスチック材質によって射出成形されるものであって、一回の成形によってストッパ(33)と結合部材(32)まで全て成形されるので、従来のように各々の部品を別個に成形して組立てる必要がない。   The inside of the knob (31) is hollow, and a stopper (33) in the form of a flange is formed so as to be in contact with the end of the spring (42) along the outer end of the end where the coupling member (32) is located. The knob (31) is injection-molded with a plastic material, and since the stopper (33) and the coupling member (32) are all molded by a single molding, each part is molded separately as before. There is no need to assemble it.

発熱体の支持円筒(15)を覆う中空形態のカバーは、内側カバー(34)と外側カバー(35)からなる。内側カバー(34)の一部は発熱体の支持円筒(37)と当接しており、ノブ(31)を引っ張ると発熱体ケース(40)が内側カバー(34)の端部を押して外側カバー(35)もともに引っ張り出されるようになる。内側カバー(34)の中間部分は直角に曲折してスプリング係止顎部(36)を形成する。外側カバー(35)は内側カバー(34)と結合され、発熱体ケース(40)がソケット内のバイメタル部材に捕獲されない状態では発熱体ケース(40)が外側カバー(35)の内部に位置するように構成される。   A hollow cover that covers the support cylinder (15) of the heating element includes an inner cover (34) and an outer cover (35). A part of the inner cover (34) is in contact with the support cylinder (37) of the heating element, and when the knob (31) is pulled, the heating element case (40) pushes the end of the inner cover (34) and pushes the outer cover (34). 35) will also be pulled out together. A middle portion of the inner cover (34) is bent at a right angle to form a spring locking jaw (36). The outer cover (35) is coupled to the inner cover (34) so that the heating element case (40) is positioned inside the outer cover (35) when the heating element case (40) is not captured by the bimetal member in the socket. Configured.

一方、スプリング(42)はノブ(31)のストッパ(33)と内側カバー(34)のスプリング係止顎部(36)との間に挟持され、内側カバー(34)と発熱体の支持円筒(37)との間の空間に設けられるが、この時スプリング(42)が発熱体の支持円筒(37)と当接しないことで、通電しなくなる恐れがあるので、発熱体の支持円筒(37)の上端から外側に曲折したスプリング接触片(39)を発熱体の支持円筒(37)と一体に形成し、常時スプリング(42)の端部と当接するようにする。   On the other hand, the spring (42) is sandwiched between the stopper (33) of the knob (31) and the spring locking jaw (36) of the inner cover (34), and the inner cover (34) and the support cylinder ( 37), but the spring (42) does not come into contact with the heating element support cylinder (37) at this time, so there is a possibility that the current will not be supplied.Therefore, the heating element support cylinder (37) A spring contact piece (39) bent outward from the upper end of the spring is formed integrally with the support cylinder (37) of the heating element so as to always contact the end of the spring (42).

本実施例でのスプリング接触片(39)は、発熱体の支持円筒(37)の上端全体が撓む部分を意味するが、図１ないし図５での発熱体の支持円筒(15)のように、何箇所かだけに小さなスプリング接触片(28)が結合されるように構成することができる。スプリング(42)はまたノブ(31)のストッパ(33)と内側カバー(34)のスプリング係止顎部(36)との間に挟入される。   The spring contact piece (39) in the present embodiment means a portion where the entire upper end of the support cylinder (37) of the heating element bends, but like the support cylinder (15) of the heating element in FIGS. In addition, small spring contact pieces (28) can be connected to only a few places. The spring (42) is also sandwiched between the stopper (33) of the knob (31) and the spring locking jaw (36) of the inner cover (34).
