With reference to FIG. 2 and FIG. 4, the docking connector 2 includes an insulating body 30 and at least one docking terminal 40.
The insulating body 30 is a substantially rectangular body. A bottom face of the insulating body 30 protrudes downward to form a slide rib 31 extending along a front-to-rear direction. A positioning lump 32 is protruded downward at the bottom face of the insulating body 30 and located behind a rear end of the slide rib 31. A bottom face of a front end of the insulating body 10 is defined as a slope 36. A guiding lump 33 is protruded frontward at the slope 36 and is in a straight line with the slide rib 31. The bottom front corner of the guiding lump 33 is designed as chamfer or fillet. The insulating body 30 defines at least one positioning hole 34 corresponding to the fastening hole 13 of the supporting body 10 and penetrating vertically through the insulating body 30. The positioning hole 34 has a first positioning groove 341 concaved upward from the bottom face of the insulating body 30 and a second positioning groove 342 extending upward from a top end of the first positioning groove 341 to penetrate through a top face of the insulating body 30. The bottom face of the insulating body 30 further protrudes downward to form a plurality of convex projections 35. The convex projections 35 and the positioning holes 34 are arranged alternately at intervals along the front-to-rear direction. The positioning holes 34 of the insulating body 30 are arranged in accordance with the arrangement of the fastening holes 13 of the supporting body 10. In this embodiment, the positioning holes 34 of the insulating body 30 are arranged into two rows between which the slide rib 31 extends.

Referring to FIG. 4, in assembly of the pogo pin connector 1, the probe terminal 20 is inserted upward in the fastening hole 13 of the supporting body 10. In detail, the barrel 21 of the probe terminal 20 is fixed in the second fastening groove 132 of the fastening hole 13, the plunger 22 of the probe terminal 20 is movably inserted in the third fastening groove 133 of the fastening hole 13 with the top end thereof projecting beyond the top face of the supporting body 10, and the soldering portion 23 of the probe terminal 20 is fixed in the first fastening groove 131 of the fastening hole 13 with a bottom end thereof projecting beyond the bottom face of the supporting body 10. A surface of the supporting body 10 from which the probe terminals 20 project out to electrically connect with the docking terminals 40 is designated as a mating surface (not labeled). The supporting body 10 together with the probe terminal 20 is fixed in a shell (not labeled) with the mating surface of the pogo pin connector 1 apart facing an inner side face of the shell. The shell defines an opening (not labeled) exposing the back end of the supporting body 10 outside. The headmost one of the probe terminals 20 which lastly docks with the docking terminal 40 is defined as contact terminal.

In detail, the docking portion 41 of the docking terminal 40 is fixed in the first positioning groove 341 of the positioning hole 34, and the positioning portion 42 of the docking terminal 40 is fixed in the second positioning groove 342 of the positioning hole 34 with the top end thereof projecting beyond the top face of the insulating body 10. One of the docking terminals 40 corresponding to the contact terminal is defined as detecting terminal.
In use, when the pogo pin connector 1 docks with the docking connector 2, the insulating body 30 with the docking terminal 40 passes through the opening of the shell to be slidably combined with the supporting body 10. In detail, the guiding lump 33 of the insulating body 30 guides the slide rib 31 to be positioned in the slide slot 11 of the supporting body 10, and then the slide rib 31 slides along the slide slot 11 to guide the insulating body 30 to slide forward on the supporting body 10 until the positioning lump 32 is blocked in the blocking groove 12. At the same time, the plunger 22 of the probe terminal 20 skims over the convex projections 35 of the insulating body 30 to dock with the docking portion 41 of the corresponding docking terminal 40. When the pogo pin connector 1 and the docking connector 2 are docked with each other completely, the contact terminal electrically contacts with the detecting terminal to do electro-discharge treatment.
As described above, the pogo pin connector assembly 100 utilizes the slide-out combine structure to slidably dock the docking connector 2 with the pogo pin connector 1, so that can save a lot of space. Furthermore, the electro-discharge treatment is done only when the pogo pin connector 1 and the docking connector 2 are docked with each other completely to make the contact terminal electrically contact with the detecting terminal, so that can effectively ensure no arc spark occur before the contact terminal electrically contacts with the detecting terminal.
