Abstract
Abstract A surface mount type electrical connector comprising an insulating housing having a plurality of contact receiving apertures and a plurality of contacts, each having a front contacting section, an intermediate section, and a rear section. The rear section is movably placed in a channel of the insulating housing so as to not only protect from foreign objects making short circuit or deformation but also absorb all the applied stresses uniformly. The insulating housing is mounted with a pair of mounting members to prevent warping or separation from the printed circuit board.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A surface mount type electrical connector comprising: an insulating housing having a plurality of contact receiving apertures; a plurality of contacts each mounted in each of said contact receiving apertures; said contact having a contacting section for contact with a mating connector contact, a terminal portion to be connected to a conductor of a printed circuit board, and an intermediate section between them having a pair of broadened engaging members; said contact receiving aperture having a pair of grooves for receiving said broadened engaging members to retain said contact therein; and a plurality of receiving channels each communicating with said receiving aperture for receiving a rear section of said contact behind said broadened engaging members in such a manner that said rear section may be slidably movable in said grooves.
Claim 2
Dependent Claim
130 words
A surface mount type electrical connector comprising: an insulating housing having a plurality of contact receiving apertures; a plurality of contacts each mounted in each of said contact receiving apertures; said contact having a contacting section for contact with a mating connector contact, a terminal portion to be connected to a conductor of a printed circuit board, and an intermediate section between them having a pair of broadened engaging members; said contact receiving aperture having a pair of grooves for receiving said broadened engaging members to retain said contact therein; and a plurality of receiving channels each communicating with said receiving aperture for receiving a rear section of said contact behind said broadened engaging members in such a manner that said rear section may be slidably movable in said grooves.
Claim 3
Dependent Claim
30 words
