Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connector assembled by connecting a connection cord to a connector body, in which the connection cord to be connected to the connector body is firmly connected to the connector body. The present invention relates to an improvement of a seat plate-shaped clamp fitting for electrically connecting a shield wire, which is formed in a tubular shape in the lower layer of the outer skin of a connection cord, to the outer pole of a connector body.

[Prior Art] As shown in FIGS. 1 and 2, the connector A is usually provided with a connecting cord on the rear end side of the contacts 1 ... Assembled and held inside the connector body a formed of a metal material. When connecting the ends of the core wires 20 ... Of b by soldering or the like to connect the connection cord b to the connector main body a, the outer periphery of the outer sheath 21 of the connection cord b is previously made into a seat plate by a metal material. The formed clamp metal fitting c is inserted, and the clamp metal fitting c is attached to the outer cover 2 of the connection cord b.
Crim on the outer periphery of 1 and clamp clamp c in that state,
The connection cord b pulled out from the cord outlet 30 is fixed to the cord outlet 30 on the rear end side of the connector body a by an appropriate means such as caulking.
To be firmly connected to. Then, at this time, the outer shell 21 and the core wire 2 of the connection cord b are knitted in a mesh tubular shape.
The shielded wire 22 interposed between the outer cover 21 and the outer cover 21 is exposed by peeling the outer cover 21, and the bundled wires are folded back on the outer peripheral surface of the outer cover 21 as shown in FIG.
By caulking, the shield wire 22 and the outer pole sleeve 31 provided on the connector body a are electrically connected and conducted by the clamp metal fitting c made of this metal material.

[Problems to be Solved by the Invention] However, the connection between the shield wire 22 and the outer pole sleeve 31 of the connector body a, which is made by the clamp fitting c, is folded back as shown in FIG. A bundle of shielded wires 22 sandwiched between the outer peripheral surface of the outer cover 21 of the connection cord b and the inner peripheral surface of the clamp fitting c is made of a metal material on the outer peripheral side of the bundle of shielded wires 22. Although it is pressed against the inner peripheral surface of c, on the inner peripheral side, it comes into pressure contact with the outer peripheral surface of the outer cover 21 of the connecting cord b made of an insulating material, so that the clamp metal fitting c made of a metal material is pressed. However, there is a problem that only one side surface of the outer circumference of the bundle of shielded wires 22 comes into contact with each other, so that electrical continuity between the connector body a and the shielded wires 22 is not stable.

In addition, the shield wire 22 that is folded back and sandwiched between the outer peripheral surface of the outer skin 21 of the connection cord b and the inner peripheral surface of the clamp metal fitting c is made of metal if it is on the inner peripheral surface of the clamp metal fitting c and the contact surface. Although it is firmly bonded by contact with the metal, the contact surface with the outer peripheral surface of the connection cord b is slippery due to the contact between the metal and the synthetic resin material. There is a problem in that the clamped portion of the shield wire 22 is displaced, and the movement thereof makes the clamp of the shield wire 22 and the clamp of the connection cord b uncertain.

[Purpose] The present invention has been made in order to solve these problems that have occurred in the conventional means, and a shielded wire of a connection cord is provided via a clamp fitting for connecting the connection cord to the connector body a. And the connector body are electrically connected so that the shield wire and the clamp metal fitting are connected with the shield wire sandwiched between the metal material and the metal material. It is an object of the present invention to provide a new means for stabilizing the electrical continuity with respect to, and for securely connecting the clamp metal fitting to the end of the folded shield wire and the connection cord.

[Means for Solving the Problem] In the present invention, as a means for achieving this object, an inner peripheral surface of a main body formed in a seat plate shape having a through hole for a connecting cord in a central portion, A notch groove that is crushed to reduce the width of the main body in the radial direction by radial pressure from the outer peripheral side to the main body is formed to a depth to hold the end part of the shielded wire that is stripped from the connection cord and bundled. Then, in the cut groove, hold the end portion of the shield wire that is stripped from the connection cord fitted in the insertion hole and collected into a bundle, and press the cut groove by the pressure from the outer peripheral side of the main body. The present invention proposes a clamp fitting for a connector which is crushed to clamp the end portion of the shielded wire while crimping the outer peripheral surface of the connection cord.

It is formed in a seat plate shape so as to correspond to the outlet port 30. The main body 4 is provided with a cleavage portion 41 for facilitating radial crushing when caulking the connection cord b inserted into the insertion hole 40 to the outer periphery thereof. Further, on the outer peripheral surface, there are formed protrusions 42 that fit into the fitting notches 32 provided in the cord outlet 30 of the connector body a.

The clamp having the insertion hole 40 is formed by a bent portion formed on the clamp metal fitting c in order to concentrate the deformation so that the deformation is performed by bending with a certain portion as a pivot. On the inner peripheral surface of the metal fitting c,
It is configured by forming a cut groove 50 that is cut out toward the outer peripheral direction to narrow the width of the clamp metal fitting c in the radial direction in a plan view. The cut groove 50 for forming the bent portion d for concentrating this deformation has the shield wire 22 that is exposed from the connection cord b and collected into a bundle, as shown in FIGS. 8 and 9. , The cut groove 5 as shown in FIG.
