Abstract
Abstract A two piece type electrical connector is provided which is matingly connect together boards in a designated correct polarity relation. A pair of first latch members L-shaped in cross-section are projected one at each end of a mother board-side housing and each have a ridge-like friction latch. A pair of second latch members L-shaped in cross-section are projected one at each end of a daughter board-side housing. One surface side of the second latch member has a projection inserted into the guide groove. One section of the projection has a recess-like friction latch frictionally engageable with the ridge-like friction latch. When the projection of the second latch member is inserted into the guide groove of the first latch member, the mother board-side housing is connected to the daughter board-side housing through the frictional engagement of the recess-like friction latch with the ridge-like friction latch so long as the mother board-side housing and daughter board-side housing are positioned in a designated correct relation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
252 words
An electrical connector for connecting a first circuit board to a second circuit board, comprising: a first housing mountable on the first circuit board, the first housing having a first latching member extending longitudinally from each end of the first housing, each of the first latching members having a guide groove which is parallel with a mating direction of the first housing and including a transverse ride positioned in the guide groove and at least partially intersecting the guide groove normal to the mating direction of the first housing; a plurality of first contacts positioned in the first housing for establishing an electrical interconnection to the first circuit board; a second housing mountable on the second circuit board, the second housing having a second latching member extending longitudinally from each end of the second housing, each of the second latching members having a projection which is parallel with a mating direction of the second housing and including a transverse recess which is at least partially intersecting the projection normal to the mating direction of the second housing; and a plurality of second contacts positioned in the second housing for establishing an electrical interconnection to the second circuit board; whereby as the projection of the second housing is fittedly inserted into the guide groove of the first housing, the first and second housings are matingly connected and latched to each other through a frictional engagement of the transverse ridge and the transverse recess and the first and second contacts are matingly connected together.
Claim 2
Dependent Claim
252 words
An electrical connector for connecting a first circuit board to a second circuit board, comprising: a first housing mountable on the first circuit board, the first housing having a first latching member extending longitudinally from each end of the first housing, each of the first latching members having a guide groove which is parallel with a mating direction of the first housing and including a transverse ride positioned in the guide groove and at least partially intersecting the guide groove normal to the mating direction of the first housing; a plurality of first contacts positioned in the first housing for establishing an electrical interconnection to the first circuit board; a second housing mountable on the second circuit board, the second housing having a second latching member extending longitudinally from each end of the second housing, each of the second latching members having a projection which is parallel with a mating direction of the second housing and including a transverse recess which is at least partially intersecting the projection normal to the mating direction of the second housing; and a plurality of second contacts positioned in the second housing for establishing an electrical interconnection to the second circuit board; whereby as the projection of the second housing is fittedly inserted into the guide groove of the first housing, the first and second housings are matingly connected and latched to each other through a frictional engagement of the transverse ridge and the transverse recess and the first and second contacts are matingly connected together.
Claim 3
Dependent Claim
90 words
The electrical connector of claim 1, wherein the first housing comprises a receptacle outer metal body, the first latching members being formed as part of the receptacle outer metal body, and wherein the second housing comprises a plug outer metal body, the second latching members being formed as part of the plug outer metal body; whereby an electrical shield is formed around the first and second contacts and sustained through the frictional engagement of the transverse ridge and the transverse recess when the housings are matingly connected to each other.
Claim 4
Dependent Claim
17 words
