Embodiment

See also Fig. 1 to Fig. 3, basically, signal socket 1 of the present utility model is to form with a communication signal plug 2 interconnection.

Wherein, signal socket 1 is the socket of known RJ45 type, its the place ahead is provided with an opening 11, for communication signal plug 2 intercalations of homotype, rear seat wall 12 is then opened eight seat grooves 121, the assembling that supplies a contact terminal 13 respectively, oblique extension one shell fragment 131 of these contact terminal 13 free ends, with after the communication signal plug chatted 2 form being connected of electrical signals, but this is a known technology all, does not intend giving unnecessary details at this.And design feature of the present utility model is, the flat face stage casing of this contact terminal 13 is recessed to form a stopper section 132 downwards, and its corresponding shell fragment 131 trends in bottom also form an inclined-plane 132a.

The communication signal plug 2 of homotype is known, the corresponding aforementioned opening 11 of its size, can embed, and a pad groove 21 is respectively opened in corresponding contact terminal 13 positions, end, assembling one contact mat 22 in it, contact with shell fragment 131, connect then oblique extension one snap-latch piece 23 in bottom to form electrical signal, after embedding opening 11, form the snapping effects with the catching groove 14 of its bottom, make

communication signal plug

2 and 1 both the unlikely disengagings of signal socket, and the form of group after upright promptly as shown in Figure 1 to Figure 3, because each shell fragment 131 is and contact mat 22 Elastic Contact of filling up in the groove 21, make the shell fragment 131 unlikely stopper sections 132 of touching, therefore, can be embedded at location in the opening 11 smoothly.

See also Fig. 4, if the size of the communication signal plug 2 of homotype is under the situation of maximum allowance, because the degree of depth of pad groove 21 still is enough to make shell fragment 131 to contact with contact mat 22, therefore, though shell fragment 131 inner edges touch stopper section 132, effect is kept out in unlikely formation, still is that effective signal connects.Therefore, when the utility model combines with the communication signal plug 2 of homotype, the embarrassed shape that unlikely generation can't intercalation.
