Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is utilized in the technical field of electrical connectors, and particularly relates to an electrical connector having a shield member formed of a metal sheet material within a housing.

(Prior Art and Problems) Conventionally, this type of connector is known, for example, as shown in Japanese Utility Model Application No. 59-79986. The cover metal, which is a shielding member made of a metal material of this conventional connector, is equipped with a lid portion that has a curved arm shape that surrounds the cable and has teeth that protrude from the inner edge, and deforms the lid portion toward the cable side. This causes the teeth to bite into the insulation sheath of the cable, and as a result, the shield wire is connected to the cover metal via the teeth.

In the above-mentioned conventional electrical connector, the shield wires are in contact only through the biting of the teeth, so the shield member and the cable shield wire are not firmly connected, so the cable is disconnected. When the shield wire is pulled, twisted, or inserted into or removed from a mating connector by force, the shield wire easily separates from the shield member, resulting in poor contact or loss of shielding effect.

(Means and effects for solving the problems) In order to solve these problems, the connector according to the present invention has a structure in which the ends of the cables are exposed by peeling off the ends of the jackets of the cables with shielded wires. An electrical connector comprising a contactor and a shield member disposed in an insulating housing to respectively connect a core wire and a shielded wire, the shield member comprising a shield contact portion and a shield wire connection portion, the shield wire connection portion is provided with a mooring part for mooring and connecting the exposed shield wire of the cable and pulled out to the side, and a locking part that elastically locks to the stepped part of the housing. When the shield member is installed,
The mooring part of the shield member forms a protruding part from the cable side end face of the housing, and after the core wire and the shield wire are connected, molding is performed to integrally connect the insulating housing and the cable end so as to cover at least the protruding part. formed by a part;

According to the present invention as described above, the shield wire is firmly held by being entwined with the arm-shaped or hole-shaped mooring portion, or further crimped with the mooring portion formed as a crimping piece. It will never come off. Furthermore, since the mooring portion protrudes from the housing on the cable side, when the shielded wire is connected, the connecting portion will form a protrusion, and the outer sheath of the cable will cover this portion. When molded together with the peeling part, the mold is strongly bonded so that the mold is applied. Moreover, since the cable and the mooring section are connected by a soft shielded wire, even if an external force is applied to the cable, this external force is not transmitted to the mooring section, and the shielded wire will not come off from the mooring section.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings. FIG. 1 is an exploded perspective view of the main parts of the electrical connector of this embodiment and shows the state before shield connection, and FIG. 2 is a half-longitudinal sectional view showing the electrical connector of FIG. 1 in an assembled state.

A contact holding hole 23 for receiving and holding a contact 30, which will be described later, is formed with an opening at the upper end.
A holding groove 24 for receiving and holding the shielded wire connection part 15 is formed in a portion near the outer periphery of the holding part 22 . The upper part of the holding part 22 has a stepped part 2.
5', and an opening 25 communicating with the upper end and the outer periphery is formed. The flange portion 26 formed as an annular protrusion at the center of the outer periphery of the housing is
It serves to prevent the cover 40, which will be described later, from coming off.

The contact 30 is made of a conductive metal material, and has a contact portion 31 that contacts the contact of the mating connector at the tip, and a core wire 61 of the cable 60 at the rear end.
A connecting portion 32 is provided for connection with the.

On the other hand, the cover 40 is formed, for example, by molding an insulating material, and protects the upper part of the housing 20, the shield line connection portion of the cable, etc., and reinforces the strength when the cable is bent.

The procedure for assembling the connector configured as described above is as follows.

First, as shown in FIG. 1, the shield member 10 is placed below the housing 20, and the shield wire connection portion 15 of the shield member 10 is connected to the housing 2
0 into the holding groove 24. Then, the lower end of the tongue portion 17 formed on the shield wire connecting portion 15 is elastically engaged with the stepped portion 25' of the opening 25 of the housing 20, and the shield member 10 is prevented from coming off downward. A shielded wire connection portion 15 having an arm-shaped portion 16 protrudes from the rear (upper) end surface of the housing 20.

Next, as disclosed in FIG.
Connect 0 with solder or crimp. The shield wire 62 is exposed after the coating is peeled off.
After it is made into a linear shape, it is inserted into the cut groove 16A of the shield member 10, entwined with the arm-shaped portion 16, and fixed by soldering.
