The shield wire 100 and the outer conductor terminal 112 are electrically connected by crimping the outer conductor barrel 118 integrally formed behind the outer conductor 2 to the outer conductor braid 106.

As another conventionally known shield terminal connection structure, for example, a shield terminal connection structure connected to a BNC type connector is known. 16 and 17 show the terminal connection structure. The connection structure shown in FIG.
The outer conductor braid 206 is exposed by peeling off the insulating jacket 208 at the end portion of the above, and the inner conductor pin (terminal) 210 is attached to the outer conductor braid 206 at the tip of the exposed portion and the exposed core wire 202 by peeling the insulating inner jacket 204. Crimping connection and insulation jacket 20
8 is passed through the sleeve 212, the rubber ring 214 and the clamp 216 to expose the exposed outer conductor braid 20.
6 is placed on the outer side of the sleeve 212 so that the rubber ring 214 is sandwiched between the sleeve 212 and the clamp 216. Then, the outer conductor terminal 218 is inserted into the shielded wire 200 up to the base end of the cylindrical screw portion 217 of the fastening member 216,
Although not shown, after inserting the inner conductor pin (terminal) 210 into the terminal accommodating portion in the insulator pre-assembled to the outer conductor terminal 218, the cylindrical screw of the fastener 216 is inserted into the insertion tube portion 219 of the outer conductor terminal 218. The portion 217 is screwed in to electrically connect the shield wire 200 and the outer conductor terminal 218.

[0004] In the connection structure shown in FIG. 17, the outer conductor braid 206 is exposed by peeling off the insulating jacket 208 at the end of the shield wire 200, and further, the outer conductor braid 206 at the tip of the exposed portion is removed.

[0005]

However, FIG.
In the terminal connection structure of the shield wire as shown in the above, since the outer conductor barrel provided behind the outer conductor terminal is connected by crimping the outer conductor braided part with the soft insulation jacket as a base, When the outer conductor barrel has a weak fixing force at the connection part and a large load such as a tensile force is applied to the shielded wire from the outside, or when the shielded wire is exposed to vibration over a long period of time, etc. The connection with the barrel may be loosened.

[0006] The operation of reversing the outer conductor braid to the insulating sheath side is performed manually or by using a reversing device. In the case of manual labor, it takes time and time to reverse the outer conductor braid. In addition, there is a problem in work efficiency such that the outer conductor braid is separated during the work and cannot be completely inverted to the insulating jacket side, and when the reversing device is used, the reversing device is expensive, etc. Problems such as high working costs.

Further, as shown in FIG. 16 and FIG.
In the terminal connection structure of the shield wire connected to the NC type connector, the outer conductor braid is crimped by the outer conductor barrel using the sleeve as an underlay, so that the fixing force of the connection portion is maintained to some extent, but before the outer conductor braid is folded. It is necessary to insert a sleeve or fastening metal in advance, or because the sleeve is annular or cylindrical, it moves along the cable, fixing the sleeve at a predetermined position of the outer conductor braid In addition, it is necessary to perform the operation of inverting the outer conductor braid to the insulating jacket side manually or by using an inverting device, and there is a problem in terms of operation efficiency or operation cost.

The problem to be solved by the present invention is to increase the fixing force (tightening force) between the outer conductor barrel of the outer conductor terminal which is fastened and fixed to the connection terminal side of the shield wire and the shield wire,
An object of the present invention is to provide a terminal connection structure for a shielded wire capable of permanently and stably maintaining the tightened state. This is intended to improve the efficiency of the work of connecting the shielded wires to the terminals.

[0009]

According to the present invention, there is provided a terminal connecting structure for a shielded wire according to the present invention.
As described in the above, between the insulating inner jacket covered around the core wire on the terminal side of the shielded wire and the outer conductor braid covered therearound, a petal-shaped folded back of the outer conductor braid at one end of the sleeve cylinder. A metal sleeve having a braided folded piece is inserted, and the outer conductor braid folded outward by the braided folded piece is placed behind the outer conductor terminal to which the inner conductor terminal connected to the core wire of the terminal of the shielded wire is attached. It is characterized by being fixed by crimping using an outer conductor barrel provided integrally with the outer conductor barrel.

[0010] According to the shield wire terminal connection structure having the above-described structure, the reversing operation of the outer conductor braid of the shield wire is extremely efficiently performed by using the metal sleeve, and the highly rigid metal sleeve is braided. Since the wire is placed under the wire, a sufficient fixing force can be provided between the outer conductor barrel and the shield wire. As a result, a sufficient connection strength can be maintained under the usage environment of the conventionally used shielded wire, and the current usage load limit is exceeded,
It can also be expected to be used in environments where a higher load is applied.

Further, the outer conductor braid folded back toward the insulating jacket by the petal-shaped braided folding piece provided at one end of the sleeve sleeve of the metal sleeve used for the reversing operation of the outer conductor braid is protruded forward. In addition, the movement of the metal sleeve in the axial direction of the shield wire is regulated by the outer conductor barrel crimped to the outer conductor braid, so that the metal sleeve does not come off from the connection part, and the normal connection between the shield wire and the outer conductor terminal. Electrical connection is maintained.

According to the present invention, in addition to the petal-shaped braided folded piece provided at one end of the sleeve cylinder, the metal sleeve may be similar in petal position by being slightly displaced from one end in the cylindrical direction. It is preferable that braided folded pieces are provided on the outer peripheral surface of the sleeve cylinder, and the petal braided pieces are alternately arranged in the circumferential direction. With this, when the metal sleeve is inserted between the outer conductor braid of the shielded wire and the insulating inner jacket, and the outer conductor braid is inverted toward the insulating outer sheath, when only the braided folded piece at the end of the sleeve cylinder is used, There is a possibility that a part of the outer conductor braid leaks from the gap between the braided folded pieces and cannot be completely inverted. In this manner, the petal-shaped braided folded piece is connected to the end edge of the sleeve cylinder. Since the outer conductor braid is provided twice in the peripheral surface portion, the inversion leakage of the outer conductor braid can be effectively prevented.

According to a third aspect of the present invention, the metal sleeve includes a plurality of outward locking pieces that cut into the outer conductor braid on the peripheral surface of the sleeve cylinder to prevent the metal sleeve from being pulled out. It is preferable that a plurality of inward locking pieces are formed to bite into the insulating inner cover and prevent the metal sleeve from being pulled out. Thus, even if a tensile force acts on the connection between the shielded wire and the outer conductor barrel, these locking pieces function as stoppers, and the removal of the metal sleeve is prevented.
In this case, either one of the outward locking piece and the inward locking piece may be provided, or both may be provided. These locking pieces are formed so as to be inclined outward or inward toward the end of the cylinder where the petal-like braided folded piece of the sleeve cylinder is formed. Effective in stopping.

Further, the metal sleeve may be provided with a concave hole or a recess on the peripheral surface of the sleeve cylinder for reducing the contact area between the metal sleeve and the insulating inner coat or the outer conductor braid. Preferably, a plurality of notch holes are formed. Thereby, when the sleeve sleeve of the metal sleeve is inserted between the outer conductor braid of the shielded wire and the insulation sheath, the contact area between the peripheral surface of the sleeve sleeve of the metal sleeve and the insulation sheath or the conductor braid is small. As a result, the contact resistance is reduced, so that a smooth insertion operation of the metal sleeve is achieved. In this case, it is desirable to appropriately select the shape, size, number, and the like of the concave pits and cutouts provided in the metal sleeve according to the size of the shield wire.

Further, the metal sleeve comprises a plurality of divided pieces divided by a plurality of notches extending in the cylinder direction of the sleeve cylinder, and the metal sleeve faces inward near the middle of each divided piece. , And the insertion side edge of the shielded wire may be bent outward. In this case, when the sleeve sleeve of the metal sleeve is inserted between the insulating inner sheath and the outer conductor braid, the inward bent portion provided in the middle of each divided piece of the sleeve sleeve is formed on the outer peripheral surface of the insulating inner sheath. When they come into contact with each other, the outer conductor braid is easily pushed outward by the spring elasticity of the sleeve cylinder, and the work of folding the outer conductor braid is performed more smoothly.

On the other hand, the form of the outer conductor barrel provided on the outer conductor terminal is, as described in claim 6, whether the outer conductor barrel is formed in an annular shape having an inner diameter substantially matching the outer diameter of the shielded wire. Alternatively, a configuration having a pair of opposing crimping pieces may be adopted. Accordingly, in the case of the configuration of claim 6, when the outer conductor braid of the shielded wire is crimped to the outer conductor terminal, the outer conductor braid can be uniformly crimped, and the connection between the shielded wire and the outer conductor barrel can be performed. The fixing force of the portion can be further increased.

As in the terminal connection structure for a shielded wire according to claim 7, the outer conductor barrel has a pair of crimping pieces facing each other curving inwardly, and the metal sleeve has a petal-like braided folded piece. Has a curved shape corresponding to each of the crimping pieces, and the terminal of the shield wire is inserted into the outer conductor barrel with a metal sleeve inserted and assembled, and the petals are formed by the crimping pieces of the outer conductor barrel. The outer conductor braid of the shielded wire may be crimped and fixed in a state where the folded braid is pressed and the rotation of the shielded wire is prevented.

In this case, when the shield wire is inserted into the outer conductor barrel, a pair of crimping pieces of the outer conductor barrel serve as a guide for a petal-shaped braided folded piece corresponding to the shape,
Since the rotation of the shielded wire is prevented, the positional relationship between the inner conductor terminal and the outer conductor terminal connected to the end of the shielded wire and the positional relationship with the terminal receiving portion in the insulator may be maintained, resulting in poor connection. Be avoided.

Further, like the shielded wire according to claim 8, notches are formed on both sides of the outer conductor barrel provided behind the outer conductor terminal, and the petal-shaped braided folded piece of the metal sleeve is formed. The outer conductor barrel has a shape to be fitted into notches formed on both sides of the outer conductor barrel, and the terminal of the shield wire is inserted into the outer conductor barrel in a state where the metal sleeve is inserted and assembled. The outer conductor braid of the shielded wire may be crimped and fixed in a state in which the petal-shaped braided folded piece of the metal sleeve is fitted into the notch and rotation of the shielded wire is prevented.

According to this, when the shield wire into which the metal sleeve is inserted and assembled is attached to the outer conductor terminal, the braided folded piece of the metal sleeve is fitted into the notch formed in the outer conductor barrel. Since the rotation of the shielded wire is prevented, the positional relationship in a state where the tip of the inner conductor terminal connected to the end of the shielded wire is also fitted into the terminal accommodating portion in the insulator pre-assembled to the outer conductor terminal. The connection is maintained, and a connection failure is avoided.

According to a ninth aspect of the present invention, in addition to the pair of crimping pieces facing each other on the outer conductor barrel provided on the outer conductor terminal, an outer conductor is provided on the sleeve cylinder of the metal sleeve. It has a braid holding piece that prevents the braid from protruding to the crimping piece side, and assembles a shield wire in which a metal sleeve is inserted and assembled into an outer conductor barrel consisting of a pair of crimping pieces facing the outer conductor terminal. If the two crimping pieces of the outer conductor barrel are crimped and connected to the braided holding piece provided on the metal sleeve, the braided holding piece provided on the metal sleeve even if a gap occurs in the contact portion between the crimped pieces. Thus, the outer conductor braid is prevented from protruding from the gap.
