Abstract

The utility model discloses a probe connector including an insulation body, a probe terminal, an insulation sleeve, conducting terminals, an accommodation pedestal and an elastic piece. The insulation body is provided with a probe terminal groove and a conducting terminal groove. The top of the probe terminal can protrude outside the probe terminal groove flexibly. A hole groove is arranged in the bottom of the probe terminal in an inward manner. The insulation sleeve sleeves outside the bottom of the probe terminal in a dismountable manner and is accommodated in the probe terminal groove. The conducting terminals are arranged in the conducting terminal groove. Each of the conducting terminals is provided with a contact part. The contact part protrudes into the probe terminal groove flexibly and abuts against the side face of the probe terminal or the insulation sleeve. The accommodation pedestal is enclosed in the bottom of the probe terminal groove. The elastic piece is received in the probe terminal groove. And the top end of the elastic piece abuts against the probe terminal while the bottom end abuts against the accommodation pedestal. In the utility model, by arranging the insulation sleeve, the generation of arc effect between the probe connector and a butting connector is avoided.

Embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.

[0023]See also Fig. 1, Fig. 2 and Fig. 3, the utility model probe connector comprises an insulating body 10, at least one probe terminal 20, at least one insulating sleeve 30, at least one conducting terminal 40, at least one ccontaining base 50 and at least one elastic component 60.

Said insulating body 10 offers several sound end pilot trench that run through insulating body 10 up and down 11 and upwards offer and several conducting end pilot trench 12 that communicate with sound end pilot trench 11 from insulating body 10 diapire both sides.

It is cylindric that probe terminal 20 roughly is; It is installed in the sound end pilot trench 11 of insulating body 10 and the top protrudes from outside the sound end pilot trench 11 movably; Probe terminal 20 bottoms offer hole slot 21 to probe terminal 20 inside; Probe terminal 20 outwards convexes with a card rib 22 near the bottom peripheral region, and probe terminal 20 outwards convexes with a boss 23 in card rib 22 top peripheries.

Said insulating sleeve 30 removably cutting ferrule outside probe terminal 20 lower ends and be contained in the sound end pilot trench 11.Particularly, insulating sleeve 30 inner corresponding card ribs 22 radially are concaved with a draw-in groove (figure does not show), and card rib 22 is sticked in the draw-in groove.

Said conducting terminal 40 places in the conducting end pilot trench 12; Each conducting terminal 40 have a tabular holding parts 41, upwards slope inwardly from holding parts 41 upper ends contact sites 43 and that the elastic arm portion that extends to form 42, extends to form from the 42 terminal bendings of elastic arm portion from holding parts 41 lower ends the outside weld parts 44 that extend to form of bending; The holding parts 41 of conducting terminal 40 is immobilizated in the conducting end pilot trench 12; Contact site 43 can flexiblely stretch in the sound end pilot trench 11 of insulating body 10 and be connected on boss 23 or the insulating sleeve 30, and weld part 44 is welded on the external circuit board (figure does not show).

Said ccontaining base 50 is closed in sound end pilot trench 11 bottoms, has the Plug Division 52 of an end of ccontaining tube 51 and one this ccontaining tube 51 of sealing cylindraceous.Particularly, ccontaining tube 51 is closed in sound end pilot trench 11 bottoms, and stretch out outside sound end pilot trench 11 bottoms Plug Division 52.

Said elastic component 60 is contained in the sound end pilot trench 11, and the top stretches into and be resisted against hole slot 21 groove roofs, and elastic component 60 bottoms are stretched into and are resisted against in the ccontaining tube 51 of ccontaining base 50.

The operation principle of the utility model probe connector is following:

The contact site 43 of conducting terminal 40 is connected on the insulating sleeve 30 when not in place when probe terminal 20 does not press down or presses down, so probe terminal 20 and not conducting of conducting terminal 40;

When probe terminal 20 presses down when putting in place, thereby probe terminal 20 compression elastic pieces 60 move down, and make boss 23 conductings of contact site 43 with the probe terminal 20 of conducting terminal 40, thus probe terminal 20 and conducting terminal 40 conductings.

When pressing down sound end 20, because the operation fault, press down when initial; May cause single probe terminal 20 to move down earlier, yet, when single probe terminal 20 presses down when not in place; Contact site 43 is connected on the insulating sleeve 30, and this probe terminal 20 is failed and corresponding conducting terminal 40 conductings; Have only when single probe terminal 20 and press down certain displacement when putting in place; Contact site 43 is connected on the boss 23; This probe terminal 20 could with corresponding conducting terminal 40 conductings; And this moment, all probe terminals 20 of probe connector all press down certain displacement to putting in place, then all probe terminals 20 and corresponding conducting terminal 40 conductings.

In sum; The contact site 43 of the utility model probe connector through conducting terminal 40 can flexiblely stretch in the sound end pilot trench 11 of insulating body 10 and be connected on the boss 23 and insulating sleeve 30 of probe terminal 20; When all probe terminals 20 of probe connector all press down certain displacement when putting in place; Could realize all probe terminals 20 and corresponding conducting terminal 40 conductings, thereby avoid producing between probe connector and the butt connector electric arc effect.
