DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector of the type in which a tape wire is connected by pressing when an opening / closing cover is closed.

[0002]

2. Description of the Related Art As shown in FIGS. 9 to 12, an electric connector comprises a connector main body 10 and an opening / closing cover 20. When a tape wire (for example, FPC) B is fitted into the wire receiving recess 11 of the connector body 10 and the cover 20 is closed, the inside of the cover 20 presses the connection portion Ba side of the tape wire B to close the cover. A configuration in which a plurality of contact groups mounted in parallel in the connector main body 10 are connected has already been proposed.

As shown in FIG. 12, the opening / closing cover 20 has locking projections 21 and 21 on the bottom surfaces of both pivoting base ends, and these projections 21 and 21 are arranged as shown in FIG. To
The wire receiving recess 1 of the connector body 10 is fitted into the recesses 12 near the rear ends of the connector body 10.
The opening / closing cover 20 can be opened and closed centering on the projections 21 and 21 by being elastically sandwiched by elastic outer pieces 13 and 13 formed of left and right outer wall portions.

When the elastic outer piece 13 is formed, as shown in FIG. 9, a long slit 1 extending from the rear end near the middle of the outer wall of the connector body 10 is used.
4 is provided to provide elasticity.

[0005]

However, in the case of the electric connector having the above structure, there are the following problems to be improved.

(1) First, the opening / closing cover 20 is rotated about its projections 21 and 21.
Since this rotation is based on a simple engagement relationship between the respective parts, it cannot be said that the rotation is necessarily smooth, and there is a problem that the rotation is easily released.

(2) The elasticity of the elastic outer piece 13 of the connector body 10 is ensured by the long slit 14 below the elastic piece 13.
The strength of the elastic outer piece 13 tends to be insufficient and may be damaged.
There is a problem in that the pinching function of the 0 projections 21 and 21 is easily lost.

(3) Further, the connector main body 1
Since it is necessary to provide the slit 14 below the elastic outer piece 13 of 0, the height (thickness) of the connector main body 10 cannot be reduced easily, and it is difficult to reduce the size of the connector main body 10.

The present invention has been made in order to solve such a problem. Basically, the rotation shaft portion of the opening / closing cover is devised so that the strength is high and the size can be reduced. ,
An object of the present invention is to provide an excellent electrical connector that can smoothly rotate and does not easily come off.
