Patent ID: 8353730

Claim:
A probe connector, comprising: an insulating housing defining a plurality of accommodating cavities each penetrating through a rear side of the insulating housing, and a plurality of receiving cavities each penetrating through a front side of the insulating housing and connected with a front of one accommodating cavity, a blocking rib being protruded at the junction of the accommodating cavity and the receiving cavity, a top wall of each accommodating cavity being provided with an inserting slot penetrating through the rear side of the insulating housing and further connected with the receiving cavity; and a plurality of probe pin assemblies including a probe curved from a metal board and having a first base board, a second base board and an arched contact head connecting two ends of the first base board and the second base board to make the first base board and the second base board apart face each other in parallel, the other end of the first base board being perpendicularly bent downward to form a resisting board, and further having two opposite side edges thereof extended downward and then face-to-face protruded to form a pair of blocking boards, the end of the probe with the blocking boards being disposed in the accommodating cavity, and the contact head retractably stretching forward out of the receiving cavity, wherein the blocking boards can be blocked by the blocking rib to prevent the probe from sliding out of the receiving cavity, a terminal having a base plate blocking a rear end of the accommodating cavity, a bottom edge of the base plate being bent rearward to form a soldering tail projected behind the insulating housing, a top edge of the base plate extending forward to form an elastic arm fastened in the inserting slot, a free end of the elastic arm stretching into the receiving cavity and being further arched downward to form a contact portion electrically abutting against the first base board, and an elastic element received in the accommodating cavity and retractably located between the resisting board of the probe and the base plate of the terminal.
