In the connector 1 formed as mentioned above, the abutting protuberance 35 of the 1st housing 20 and bearing surface 37, in the outstanding mode in the direction intersected to the direction of engagement with the 1st housing 20 and the 2nd housing 60, are located at the opposed locations of the periphery of the 1st housing 20.In addition, the abutting protuberance 35 of the 1st housing 20 and the projected direction of bearing surface 37 are the contact direction contacted relative to the connecting pin portion 54 of male 50 along the contact portion 14 of female end 10.
Next, the situation that the 1st housing 20 of the described connector 1 of formation is engaged with the 2nd housing 60 is described.
Fig. 5 is the figure of the engagement state that the 1st housing and the 2nd housing are shown, Fig. 5 (a) to Fig. 5 (d) is the cutaway view of connector respectively.Fig. 6 is the chart that the bonding station of the 1st housing and the 2nd housing and the relation of connector insertion force are shown.Fig. 7 is the figure of the position relationship that the inner edge abutting protuberance and fitting portion is shown, Fig. 7 (a) is the B portion enlarged drawing of Fig. 5 (b); Fig. 7 (b) is the C portion enlarged drawing of Fig. 5 (c).
As shown in Fig. 5 (a), in order to make the 1st housing 20 engage with the 2nd housing 60, embed the cloudy terminal accommodation portion 21 of the 1st housing 20 at the chimeric recess 72 of the fitting portion 71 being formed at the 2nd housing 60.
Herein, the chimeric sart point in time of connector insertion force F from cloudy terminal accommodation portion 21 to chimeric recess 72 (S1 with reference to Fig. 6) for making the 1st housing 20 and the 2nd housing 60 engage increases.
Like this, when cloudy terminal accommodation portion 21 is fitted together to chimeric recess 72, the front end in the connecting pin portion 54 of male 50 is inserted into the male patchhole 23 formed in each female end sub-chamber 22 of cloudy terminal accommodation portion 21.Now, directed face 24, connecting pin portion 54 faces south, and terminal insertion hole 23 guiding is also smooth inserts.In addition, the inner edge 71a of the lower side of the fitting portion 71 of the 2nd housing 60 crosses the guide portion 38 of the lower surface 20b of the 1st housing 20, contacts with bearing surface 37.Thus, as shown in Fig. 1 (b), between the lower surface 20b of the front beyond the bearing surface 37 of the 1st housing 20 and the 2nd housing 60, become the state of the clearance C be formed with slightly.So the front of the 1st housing 20 easily conjugates relative to the 2nd housing 60, until directed face 24, connecting pin portion 54 guides terminal insertion hole 23 on the sunny side, therefore, realize connecting pin portion 54 terminal insertion hole 23 that faces south to insert more smoothly.
In addition, when embedding the cloudy terminal accommodation portion 21 of the 1st housing 20 in the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60, the engagement pawl 73 being formed at the fitting portion 71 of the 2nd housing 60 abuts with the lock pawl 31 of the lock arm 30 being formed at the 1st housing 20.
As shown in Fig. 5 (b), when the cloudy terminal accommodation portion 21 of the 1st housing 20 is embedded into the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60 further, the connecting pin portion 54 being inserted in the male 50 of male patchhole 23 is inserted into the terminal fitting portion 11 of female end 10.
At this time point, because the engagement pawl 73 of fitting portion 71 rides on the lock pawl 31 of lock arm 30, thus connector insertion force F maximum (S2 with reference in Fig. 6), later connector insertion force F reduces.
In addition, as shown in Fig. 7 (a), the inner edge 71b of the upper side of the fitting portion 71 of the 2nd housing 60 is connected to the introduction part 36 of the abutting protuberance 35 of the 1st housing 20.
As shown in Fig. 5 (c), when the cloudy terminal accommodation portion 21 of the 1st housing 20 is embedded into the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60 further, the connecting pin portion 54 of male 50 is further inserted into the terminal fitting portion 11 of female end 10.Thus, connecting pin portion 54 enters between the contact portion 14 of terminal fitting portion 11 and bottom surface sections 11a, and contact portion 14 is connected pin portion 54 and pushes and contact, and female end 10 is connected with male 50 is switched on.In addition, as shown in Fig. 7 (b), the inner edge 71b of the upper side of the fitting portion 71 of the 2nd housing 60, by the introduction part 36 of the abutting protuberance 35 along the 1st housing 20, guides to abutting protuberance 35.Like this, the inner edge 71b of the upper side of fitting portion 71 is guided to abutting protuberance 35 by along the introduction part 36 abutting protuberance 35, thus the minimizing of connector insertion force F temporarily stops (S3 with reference in Fig. 6), again reduces afterwards.
As shown in Fig. 5 (d), when the cloudy terminal accommodation portion 21 of the 1st housing 20 is embedded into the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60 further, the connecting pin portion 54 of male 50 is further inserted into the inside of the terminal fitting portion 11 of female end 10.In addition, the abutting protuberance 35 of the 1st housing 20 and bearing surface 37 become the state abutted with the inner surface of the chimeric recess 72 of the 2nd housing 60.Thus, the state that the cloudy terminal accommodation portion 21 becoming the 1st housing 20 is fitted together to very close to each otherly relative to the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60, the 1st housing 20 and the 2nd housing 60 can not loosen.
In this condition, engagement pawl 73 crosses the lock pawl 31 of lock arm 30, arrives than the position of lock pawl 31 by the rear end side of the 1st housing 20.Thus, to be pressed and the lock arm 30 of strain restores, lock pawl 31 engages mutually with engagement pawl 73.Therefore, the engagement state of the 1st housing 20 and the 2nd housing 60 is maintained.In addition, put joint and complete at this moment, connector insertion force F disappears (S4 with reference in Fig. 6).
Like this, according to the connector involved by above-mentioned execution mode, 1st housing 20 is engaged with the 2nd housing 60, thus abutting protuberance 35 and bearing surface 37 are connected to the inner surface of chimeric recess 72, therefore, it is possible to loosening of the 1st housing 20 under suppression engagement state and the 2nd housing 60, the contact stabilization of female end the 10 and male 50 kept by the 1st housing 20 and the 2nd housing 60 respectively can be improved.Thus, such as, even if can use in the vehicle such as vibrative automobile in motion, also can suppress the wearing and tearing vibrating female end the 10 and contact site place of male 50 caused as far as possible, the high connection reliability of female end 10 and male 50 can be maintained.
Particularly, abutting protuberance 35 is the contact direction contacted relative to connecting pin portion 54 along contact portion 14 with the projected direction of bearing surface 37.Therefore, abut the inner surface that protuberance 35 and bearing surface 37 are connected to chimeric recess 72, thus can suppress the 1st housing 20 and the 2nd housing 60, contact portion 14 is relative to contact direction loosening in connecting pin portion 54.Thereby, it is possible to make connecting pin portion 54 reliably improve with the contact stabilization of contact portion 14.
In addition, protuberance 35 and bearing surface 37 is abutted because the opposed locations of the periphery at the 1st housing 20 and upper surface 20a and lower surface 20b are provided with, so, balance can suppress loosening of the 1st housing 20 and the 2nd housing 60 well, the contact stabilization of female end 10 and male 50 can be improved further.
Herein, illustrate and make not arrange the 1st housing 20 of connector involved by the comparative example abutting protuberance 35 and bearing surface 37 and the joint of the 2nd housing 60 at the 1st housing 20.
Fig. 8 is the figure of the 1st housing of the connector illustrated involved by comparative example and the engagement state of the 2nd housing, and Fig. 8 (a) to Fig. 8 (c) is the cutaway view of connector respectively.Fig. 9 is the 1st housing of the connector illustrated involved by comparative example and the chart of the bonding station of the 2nd housing and the relation of connector insertion force.
As shown in Fig. 8 (a), when the cloudy terminal accommodation portion 21 of the 1st housing 20 is embedded into the chimeric recess 72 formed at the fitting portion 71 of the 2nd housing 60, the chimeric sart point in time of connector insertion force F from cloudy terminal accommodation portion 21 to chimeric recess 72 (with reference to S11 Fig. 9) increases.
After the engagement pawl 73 of fitting portion 71 is connected to the lock pawl 31 of lock arm 30, as shown in Fig. 8 (b), when the cloudy terminal accommodation portion 21 of the 1st housing 20 is embedded into the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60 further, the engagement pawl 73 of fitting portion 71 rides on the lock pawl 31 of lock arm 30, connector insertion force F becomes maximum (S12 with reference in Fig. 9), and later connector insertion force F reduces.
As shown in Fig. 8 (c), when the cloudy terminal accommodation portion 21 of the 1st housing 20 is embedded into the chimeric recess 72 of the fitting portion 71 of the 2nd housing 60 further, engagement pawl 73 crosses the lock pawl 31 of lock arm 30, arrives than the position of lock pawl 31 by the rear end side of the 1st housing 20.Thus, to be pressed and the lock arm 30 of strain restores, lock pawl 31 engages mutually with engagement pawl 73.So maintain the engagement state of the 1st housing 20 and the 2nd housing 60, in addition, joint completes, thus connector insertion force F disappears (with reference to S13 in Fig. 9).
Like this, the 1st housing 20 does not arrange abutting protuberance 35 and bearing surface 37, its connector insertion force F becomes maximum when the engagement pawl 73 of fitting portion 71 rides on the lock pawl 31 of lock arm 30.
In contrast, when involved by present embodiment connector 1, it is that the engagement pawl 73 of fitting portion 71 is when riding on the lock pawl 31 of lock arm 30 (with reference to Fig. 6) that connector insertion force F becomes most ambassador.That is, in the connector 1 involved by present embodiment, when abutting opportunity that protuberance 35 and bearing surface 37 and the inner surface of chimeric recess 72 abut and the 1st housing 20 is engaged with the 2nd housing 60, connector insertion force F becomes and departs from maximum opportunity.Thus, even if suppress the loosening structure after engaging by arranging to abut protuberance 35 and bearing surface 37 thus become on the 1st housing 20, also the maximum of connector insertion force F can be suppressed for the situation abutting protuberance 35 and bearing surface 37 be not set on the 1st housing 20 be equal to.
