Description

The combination of matrix form board to board connector

Affiliated technical field

The utility model relates to a kind of board to board connector combination, relates in particular to a kind of matrix form board to board connector combination.

Background technology

See also Figure 10, it has disclosed a kind of existing matrix form board to board connector combination 20, first connector 300 and second connector 400 that comprise mutual fastening, two connectors 300,400 are individually fixed in (not shown) on the different circuit boards, so that two circuit boards are electrically connected, thereby reach signal transmission between two circuit boards.

See also Figure 11, first connector 300 of this existing matrix form board to board connector combination 20 comprises first housing 310 and is fixed on a plurality of the first terminals 320 on first housing 310.First housing 310 has first substrate 311.The edge of the both sides, front and back of first substrate 311 all offers recess 313.The left and right sides of first substrate 311 all upwards vertically extends a sidewall 314, and the two ends of sidewall 314 vertically extend stop arm 315 along the both sides, front and back of first substrate 311 respectively.Stop arm 315 and two side 314 surround a spatial accommodation, in order to hold second connector 400.Along the bearing of trend of stop arm 315, first fixture block 316 is outstanding from stop arm 315, in order to fix second connector 400.

See also Figure 12, second connector 400 of this existing matrix form board to board connector combination 20 comprises second housing 410 and is fixed on a plurality of second terminals 420 on second housing 410.All extend a fixing feet 412 straight up and laterally extend one second fixture block 416 at four jiaos of places of second housing 410.When

second connector

400 and 300 grafting of first connector, fixing feet 412 stretches into downwards in the recess 313 of first connector 300, and first fixture block 316 of second fixture block 416 and first connector 300 is clasped mutually, thereby second connector 400 is fixed on first connector 300.

Yet, because this existing matrix form board to board connector combination 20 is clasped mutually by first fixture block 316 and second fixture block 416 and two connectors 300,400 is snapped together, first fixture block 316 and second fixture block 416 only play the fastening effect, when two connectors 300,400 were pegged graft, the user can not determine whether first connector 300 is plugged on fully with second connector 400.

The utility model content

The purpose of this utility model is to provide a kind of matrix form board to board connector combination at the defective that above-mentioned prior art exists, in first connector and the second connector grafting process of this matrix form board to board connector combination, the user can determine whether two connectors are plugged on together fully.
