FIG. 1 is a perspective view showing an embodiment of a shielded connector according to the present invention, and FIG. 2 is a longitudinal sectional view showing a state in which a shielded electric wire is connected. The shield connector 1 includes:
A connector housing 3 made of an insulating resin in which a conductive main metal shell 2 for shielding is embedded, and a rear opening 4 for terminal insertion of the connector housing 3 can be freely opened and closed by a hinge 5 integrated with the main metal shell 2. And a rear cover 7 made of insulating resin in which a conductive sub-metal shell 6 for shielding integrated with the hinge 5 is embedded.

The main metal shell 2 is formed of a terminal material such as iron or brass, and is integrally molded into a synthetic resin connector housing 3. The main metal shell 2
Is a front rectangular tubular portion 9 along the shape of the housing peripheral wall 8.
And a back gutter-like portion 10 excluding the notch opening 4, and a crimp connection portion 12 integrally and rearwardly extended from the bottom plate portion 10 a (FIG. 2) of the gutter-like portion 10 to the shielded electric wire 11.
The upper end face 10b of the gutter 10 is located on the same plane as the housing opening edge 4a.

A pair of hinges 5 and 5 are integrally formed on the upper wall 13 of the rectangular cylindrical portion 9 by being cut and raised.
The hinge 5 can be housed in the longitudinal groove 14 at the top of the housing peripheral wall 8 when the rear cover 7 is closed. The proximal end of the hinge 5, connect with the shell top wall 13 has a fulcrum 15 which is curved to radius shape in the door opening state of the rear cover 7 as shown in FIG. 2, after the end is rounded shape after the hinge 5
Sub metal shell 6 of the rear cover 7 through a square bend 16
Connected to. The rear curved portion 16 protrudes above the upper wall 17 of the rear cover 7 to the outside, and forms a substantially crank-shaped bent portion 18 that is embedded in the rear cover 7. Said rear bay <br/> bending portion 16 is prevented bending damage from incoming base implantation,
The rear cover 7 is elastically supported to provide a degree of freedom in the front-rear direction when the rear cover is assembled. In addition, the hinge 5 exerts a spring force in the rear cover opening direction in the free state, and improves the workability of inserting terminals and electric wires, which will be described later.

The sub-metal shell 6 is integrally formed of the same material as the main metal shell 2 and is bent substantially in an L-shape and follows the shape of the rear cover 7 having a shielded wire lead-out portion 19 at the rear. And is integrally molded into a substantially gutter shape. A front exposed portion 20 projecting between the pair of hinges 5 and 5 and a lower exposed portion 22 projecting downward from a side wall 21 of the rear cover 7 corresponding to the inner surface of the gutter-shaped portion 10 of the main metal shell 2. Have.

The rear cover 7 is connected to the connector housing 3.
And has an engagement frame portion 24 for the locking projection 23, and is joined and closed to the connector housing 3. In this state, the front exposed portion 20 of the sub-metal shell 6 is on the inner surface of the upper wall 13 of the rectangular cylindrical portion 9 of the main metal shell 2, and the lower exposed portion 22 is the gutter-shaped portion 10.
Surface contact with the inner surface of the side wall.

As shown in FIG. 2, the press contact terminal 34 is inserted into the connector housing 3 from the cutout opening 4 before closing the rear cover. The lead wire 25 of the shielded wire 11 is press-connected to the press-contacting terminal 34 by a pressing jig (not shown), and the terminal crimping portion 12 integrated with the main metal shell is crimp-connected to a shield portion (not shown) of the shielded wire 11. . As shown in FIG. 1, the terminal crimping portion 12 is formed by a pair of crimping pieces 26, 26.
And a central cut-and-raised piece 27 that divides the plurality of electric wires 11 into right and left. Since the terminal crimping portion 12 is integrated with the main metal shell 2, the contact resistance between the crimping portion 12 and the metal shell 2 becomes zero, and the shielding performance is improved.

FIG. 3 shows the shield connector (right side) 1
Is a longitudinal sectional view showing a state in which is connected to a mating shield connector (left side) 28. The hinge 5 of the shield connector 1 extends in the longitudinal groove 14 of the housing 3 from the rear curved portion 16 on the side of the rear cover 7 toward the front, and its distal end is bent downward to be embedded in the housing peripheral wall 8. ing. That is, the hinge 5 stands short from the fulcrum portion 15.
With the raised first support portion 5a and the rear cover 7 closed
It bends and extends straight from the tip bending portion 29 of the first support portion 5a.
Following the extending portion 5b and the rear curved portion 16 of the extending portion 5b
And the second support portion 5c on the sub metal shell side.
You. The rear cover 7 rotates about the tip bending portion 29 as a fulcrum.
You . The distal bending portion 29 is formed in accordance with the closing of the rear cover 7, and elastically supports the rear cover 7 together with the rear bending portion 16. The rectangular tubular portion 9 of the main metal shell 2 following the distal end curved portion 29 is fitted and in contact with a distal end side exposed portion 31 of a similar main metal shell 30 protruding from the distal end of the mating connector 28. Also, the hinge portion 32 of the mating connector 28
Is protected from being inserted into the front end fitting wall 33 of the shield connector 1.

[0014]

As described above, according to the invention of claim 1,
The hinge between the connector housing and the rear cover.
Is extended and the rear cover is elastically supported by the hinge
