DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made to the drawing figures to describe the present invention in detail.
With reference to FIG. 2, a retaining device 1 of the present invention comprises a board-shaped retaining member 10 and a looking member 13. The retaining member 10 has a rectangular base section 103. A side board 12 vertically extends from one edge (back edge) of the base section 103 along a lengthwise direction of the base section 103. An indentation 102 is defined at another edge (front edge) of the base section 103 and extends vertically to the side board 12, and a retention section 11 vertically bends from an end of the base section 103 and parallel to the side board 12. The indentation 102 will increase the spring of the retention section 11.
There is a slot 100 defined along the lengthwise direction of the base section. The slot 100 comprises a first portion 1001 and a pair of second portions 1002 vertical to the first portion 1001. A pair of through holes 101 in each side of the slot 100 lies near the front edge of the base section. A notch 121 is defined on the top edge of the side board 12. The retention section 11 defines a through-hole 110 thereon to engage with the locking member 13.
With reference to FIG. 4, the electrical connector 2 comprises an insulating housing 20, a plurality of contacts 22 received in the insulating housing and a shell 21. The insulating housing 20 includes a lengthways base portion 201. A rib 200 is defined on the bottom of the base portion 201 along the lengthways direction and comprises two portions, a first portion 2001 and a pair of second portions 2002 vertical to the first portion 2001. The shell 21 surrounds the insulating housing 20 with an outspread portion 23 clamped between the pair of second portions 2002, and has a soldering leg 211 and a pair of board-locking legs 212, which both used to solder the electrical connector 2 on the circuit board.
With reference to FIG. 3, FIGS. 5 and 6, the retaining device 1 is used to fasten an electrical connector 2 to an electronic apparatus (not shown). After the connector 2 is mounted on a circuit board (not shown), the retaining device 1 is set on the bottom of the connector 2, with the rib 200 set in the slot 100. The first portion 2001 of the rib 200 engages with the first portion 1001 of the slot 100, the second portions 2002 engages with the second portions 1002. And the retaining device 1 is soldered on the shell by the through holes 101. The side board 12 is put against the backside of the base portion 201 to prevent the electrical connector 2 from moving backwards from the retaining device 1. The notch 121 engages with a sidewall 210 of the shell 21. The through holes 101 sad the slot 100 are both used to fasten the retaining device 1 to the electrical connector 2, which both named as a retaining portion. The locking member 13 is riveted on the retention section 11 through the through-hole 110. And then bolt (not shown) is twist into a screw of the locking member 13 to fasten the retaining device 1 on the peripheral electronic apparatus.
However, the disclosure is illustrative only, changes may be made in detail, especially in matter of shape, size, and arrangement of parts within the principles of the invention.
