Abstract

The utility model relates to a probe which can be assembled in an insulating body. A receiving cavity is formed inside the insulating body; two ends of the receiving cavity are respectively provided with a first opening and a second opening. The first opening and the second opening penetrate through the insulating body. The probe comprises a main body and a probe head; the probe head or part of the probe head can extend out of the insulating body. The main body is provided with a sleeve barrel, and the probe head is received in the sleeve barrel. The utility model is characterized in that the probe head is provided with a spacing structure in order to prevent the length of the probe head from extending out of the insulating body. Compared with the prior art, the probe head of the probe provided by the utility model is provided with the spacing structure, so when assembled with corresponding mate structure, the spacing structure can accurately control the extending length of the probe; a stable compressing contact travel between the probe and a foreign assembly is guaranteed.

Description

Probe

[technical field]

The utility model relates to a kind of probe, especially a kind of probe that is used in the electrical connection.

[background technology]

Prior art can see figures.1.and.2, and discloses being connected of a kind of probe 1 and insulating body 2, and its middle probe comprises the main body 11 and the probe 10 that can vertically move mutually, and main body 11 is provided with a snap ring 12, to match with insulating body 2; Form a host cavity 20 in the insulating body 2, its two ends are formed with first opening 21 and second opening 22.When probe 1 is connected with insulating body 2, second opening 22 of probe 1 from insulating body 2 entered, the part of the probe 10 of probe 1 is stretched out from first opening 21, be used for compressing mutually and contact with external assembly 5, the wall interference of snap ring 12 and host cavity 20 cooperates, thereby probe 1 and insulating body 2 are fixed together.

Yet the defective of the prior art is: when probe and insulating body assembling, because it is wayward that probe, insulating body 2 and the foozle that cooperates thereof, probe are stretched out the length of insulating body 2, perhaps precision is not high, stretch out longly, probe is fractureed or crooked; Too short, make and the compression loose contact of external assembly 5.

Therefore, be necessary to carry out the probe structure improvement, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of probe, and stable compression contacting travel can be provided.

In order to reach above-mentioned creation purpose, the utility model probe can be assembled in the insulating body, form a host cavity in this insulating body, the host cavity two ends are provided with first opening and second opening, first opening and second opening run through insulating body, this probe comprises main body and can stretch out the probe of insulating body from least a portion from first opening, wherein main body is provided with sleeve, probe is contained in the sleeve, it is characterized in that: probe is provided with position limiting structure, stretches out the outer length of insulating body with the restriction probe.

Compared with prior art, the probe of the utility model probe is provided with position limiting structure, with when assembling with the corresponding matching structure, can control the length that probe stretches out more exactly, and assurance and external assembly have stable compression contacting travel.

Fig. 2 is the schematic diagram after probe shown in Figure 1 and the insulating body assembling.

Fig. 3 is the schematic diagram before the utility model probe and the insulating body assembling.

Fig. 4 is the schematic diagram after probe shown in Figure 3 and the insulating body assembling.

[embodiment]

Please refer to Fig. 3 and shown in Figure 4, the utility model the utility model probe 1 is used for and insulating body 2 assemblings, forms a host cavity 20 in this insulating body 2, and its two ends are formed with first opening 21 and second opening 22.This probe 1 comprises the probe 10 and the main body 11 that can vertically move mutually, main body 11 is provided with snap ring 12 and is used for accommodating the sleeve 13 of probe 10, further be provided with spring (not drawing among the figure) in the sleeve 13, wherein probe 10 is provided with the projection 100 (also can be the position limiting structure of other form certainly) greater than first opening 21.

During assembling, an end that probe 1 is provided with probe 1 enters from second opening 22 of insulating body 2, the part of the probe 10 of probe 1 is stretched out from first opening 21, be used for compressing mutually and contact with external assembly (not shown), at this moment, probe 10 is provided with projection 100, projection 100 can be withstood the inwall of the first opening both sides, stoped probe 10 outwards to move, control probe 1 exposes the length outside the insulating body 2, the wall interference of snap ring 12 and host cavity 20 cooperates in addition, thereby probe 1 and insulating body 2 are fixed together.

Compared with prior art, the utility model probe, syringe needle is provided with position limiting structure, with when assembling with insulating body, can control the length that probe stretches out more exactly, and assurance and external assembly have stable compression contacting travel.
