DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2 , the improved structure of connector of the present invention at least comprises an insertion-connecting socket unit 10 , a lower lid 20 , a group of pins 30 , a metallic housing 40 for an insertion slot, and a plurality of metallic covers 50 , wherein:

The insertion-connecting socket unit 10 has on the two lateral sides thereof protruding engaging posts 11 which have therebeneath recesses 12 ; a group of pin jacks 13 are provided on the end of the insertion-connecting socket unit 10 for connecting with the group of pins 30 , the insertion-connecting socket unit 10 is provided on the upper and the lower areas on the two lateral sides thereof in opposition to the metallic housing 40 with insertion dents 14 .

The lower lid 20 has at the two lateral sides thereof columns 21 which are provided on their inner sides with engaging grooves 22 and protruding engaging blocks 23 to be in corresponding in position respectively to the protruding engaging posts 11 and the recesses 12 of the insertion-connecting socket unit 10 ; and the lower lid 20 has in corresponding to the group of pins 30 a group of pin holes 24 , the columns 21 each has on the upper and lower ends thereof insertion dents 25 .

The group of pins 30 are composed of a lot of pins 31 in corresponding to the group of pin jacks 13 of the insertion-connecting socket unit 10 and to the group of pin holes 24 of the lower lid 20 .

The metallic housing 40 for an insertion slot is provided on the outside of the insertion-connecting socket unit 10 , and is provided thereon in corresponding in position to the insertion dents 14 of the insertion-connecting socket unit 10 with engaging strip portions 41 .

The metallic covers 50 are provided on the columns 21 of the lower lid 20 , and are provided thereon in corresponding in position to the insertion dents 25 of the columns 21 with engaging strip portions 51 .

When in assembling, the group of pins 30 are respectively inserted into the group of pin jacks 13 of the insertion-connecting socket unit 10 and the group of pin holes 24 of the lower lid 20 ; and after positioning of the group of pins 30 , the engaging grooves 22 of the lower lid 20 are in corresponding in position to the protruding engaging posts 11 of the insertion-connecting socket unit 10 , thereby the insertion-connecting socket unit 10 can be insertion connected to the lower lid 20 , and the recesses 12 on the insertion-connecting socket unit 10 can be engaged exactly with the protruding engaging blocks 23 of the lower lid 20 . Thereby, the insertion-connecting socket unit 10 and the lower lid 20 can be connected to each other, and the effects of positioning and fixing can be achieved.
