DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector case, and more particularly, to an electrical connector case that provides a good shielding effect and can be easily bent for assembly.

[0002]

2. Description of the Related Art FIG. 1 shows a conventional electrical connector having an insulating housing 10a including a plurality of terminals 12a and a case 11a surrounding the housing to provide a shielding effect. One end of each terminal 12a is exposed from the bottom surface of the housing 10a.

[0003]

However, in such an electrical connector, the case 11a has the housing 10
The shield effect is not given to the rear part of a, and the shield effect against electromagnetic interference is affected. Further, the conventional case structure has a large resistance when bending the case 10a. The bent portion is recessed inward, causing the problem that the edge is not vertical.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a main body having an upper plate, two side plates and a lower plate, a main body connected to one side of one side plate and bent at one side. It is an object of the present invention to provide an electrical connector case having a rear cover for sealing a rear portion of a main body. By providing the rear cover, a good shielding action is given to the rear part of the connector.

Another object of the present invention is a case of an electrical connector formed by bending a metal plate, wherein a plurality of groove-shaped fold lines are formed between inner walls of a bent portion of the case, and these fold lines are formed. It is to provide a case in which a hole is provided in a part of the line. Therefore, the case can be easily bent vertically without any inward depression. Thus, the connector has a clean appearance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Various objects and effects of the present invention are as follows.
BRIEF DESCRIPTION OF THE DRAWINGS The following detailed description can be readily understood by reference to the accompanying drawings. Referring to FIGS. 2, 3 and 4, the case of the electrical connector according to the present invention is formed of metal and includes a main body 11. The main body 11 includes an upper plate 12, two side plates 13 connected to both sides of the upper plate 12, and a lower plate 14 connected to the front ends of the side plates 13. Each of the side plate 13 and the lower plate 14 has a retaining plate 15 below it, which is inserted into a corresponding retaining hole (not shown) in the circuit board to retain the connector. Each of the two side plates 13 has a lock plate 16. The main body 11 has a hollow insertion part 17. One side plate 13 is connected to the rear cover 18.
Furthermore, between the side plate 13 and the rear cover 18, between the main body 11 and the upper plate 12, and between the side plate 1 and the upper plate 12.
3 and the lower plate 14, a plurality of fold lines 19
Is formed. These fold lines 19 are configured to have a V-shaped shape as shown in FIG. 5 or a rectangular groove shape as shown in FIG. A hole 20 is provided in a part of the fold line 19.

The case 10 surrounds the insulating housing 30 to form a connector. The housing 30 has a plurality of terminals 31 connected to a mating connector. Terminal 31
Is exposed from the lower portion of the housing 30, and is inserted into the circuit board. The insulating housing 30 has two lock grooves 32 on both sides thereof. The insulating housing 30
It is arranged in the case 10 and clamped. At this time, the lock plates 16 of the two side plates 13 are locked to the two lock grooves 32 of the insulating housing 30, and the insulating housing 30 is securely clamped in the case 10. The rear cover 18 is bent inward along a fold line 19 formed on one side of the main body 11.
Seal the back. The rear cover 18 includes a flange 21
And a hook 22. The side plate 13 has a hole 23 corresponding to the hook 22, the hook 22 is hooked into the hole 23, and the rear cover 18 is firmly clamped to the rear edge of the main body 11. Further, the flange 21
Covering the gap between the rear cover 18 and the side plate 13, the case 10 can tightly seal the housing 30.

When the case 10 is disposed so as to surround the housing 30, the upper plate 12, the side plates 13 and the lower plate 14 of the main body 11
0 corresponding top, two sides and bottom.
The rear cover 18 of the case 10 shields the rear side of the housing 30. By providing the rear cover 18,
The shielding effect of the housing 30 against EMI is improved. Furthermore, the fold line 19 on the groove provided between the side plate 13 and the rear cover 18 is
8 reduces the resistance when bending. Side plate 13
And the rear cover 18 has a vertical joining line after bending the rear cover, eliminating the problem of depression. Crease line 1
The hole 20 formed in a part of the groove 9 further reduces the resistance and allows the groove-shaped fold line 19 to be easily bent.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to this. Various changes and modifications will be apparent to those skilled in the art from the above description. It is therefore intended that these changes and modifications be included within the spirit and scope of the invention as set forth in the appended claims.
