Abstract

A probe structure comprises a pipe body, a shaft lever sheathed in the pipe body, an elastic body sheathed on the shaft lever, and a stopper equipped on a joint of the pipe body to butt against with the elastic body, and a needle for detection is inserted on the shaft lever and penetrates through a via-hole at the other end of the pipe body. Accordingly, the needle can make elastic displacement in the pipe body via the elastic body to form a simple probe structure.

Description

Probe structure

The relevant a kind of probe structure of the utility model.

Probe is mainly used in various electronic components of test and circuit board at present, probe configuration is contacted with electronic component or circuit board on test fixture, the result that will be tested by probe passes computer back through lead, to confirm whether determinand has bad place, generally needs the testing apparatus than high precision;

The probe structure of commonly using as shown in Figure 1, system is by one first body A, one spiral shell is located at the second body B in the first body A, this second body B is slidingly equipped with one the 3rd body C, the end of one needle body D passes the first body A, the second sleeve pipe B and packing are on the 3rd body C, wherein dispose an elastic body E in this second body B, the other end of this second body B directly is welded with axostylus axostyle F, so can this elastic body E is spacing between axostylus axostyle F and the 3rd body C, this exposed needle body D appropriate position disposes a limited block G, by this compression travel of needle body D is done a restriction, so that what is made the usefulness of detection.

So, it is quite complicated to commonly use structure, and assembly quite bothers, include be spirally connected, packing and welding or the like, time-consumingly take a lot of work again; The infrastructure cost of commonly using is quite high, and assembling processing is quite difficult, therefore, commonly uses probe structure and is not inconsistent economic benefit at all.

Fundamental purpose of the present utility model is to solve the disappearance of above-mentioned prior art, avoids the existence that lacks, a kind of probe structure is provided, this probe structure is simple and easy, makes the interior nationality of this needle body what body do the displacement of an elasticity by elastic body, and becomes a simple and easy probe structure.

The purpose of this utility model is to realize like this.

A kind of probe structure comprises body, needle body, elastic body, it is characterized in that this body, has the accommodation space of a hollow, and one of this body end is the bigger joint mouth of bore, the other end be bore less wear mouth; One axostylus axostyle, end of its big caliber is a top supporting part, and is placed in the aforementioned accommodation space, and this top supporting part top pulls and wear within the mouth on the side ancient piece of jade, round, flat and with a hole in its centre aforementioned, a needle body is configured on the axostylus axostyle, and penetrates the aforementioned mouth that wears; One elastic body is set on the aforementioned axostylus axostyle, and one end top is located on the aforementioned top supporting part; One backstop, the passage with a hollow, this passage wears for aforementioned axostylus axostyle, and this backstop packing is at aforementioned joint mouthful place, and the one end is the stop section of little caliber, ends this elastic body to support.

The top supporting part of this axostylus axostyle is provided with a jack.

The other end of this axostylus axostyle is provided with for lead and connects the access slot of establishing.

This elastic body can be a compression spring.

The appropriate position of this needle body disposes a limited block.

Detailed description of relevant the utility model and technology contents now are described as follows with regard to conjunction with figs.:

Fig. 1 is the structural representation of known probe.

Fig. 2 is the utility model stereoscopic synoptic diagram.

Fig. 3 is the utility model STRUCTURE DECOMPOSITION synoptic diagram.

Fig. 4 is the utility model action synoptic diagram.

Fig. 2, Fig. 3 are respectively stereoscopic synoptic diagram of the present utility model and STRUCTURE DECOMPOSITION synoptic diagram, and as shown in the figure: the utility model probe includes:

One body 1, the accommodation space 11 with a hollow, an and end of this body 1 is the bigger joint mouth 12 of bore, and the other end to be bore less wears mouthfuls 13;

One axostylus axostyle 2, one end of big caliber is a top supporting part 21, and this top supporting part 21 also is provided with one and plugs hole 211, and is installed with in the aforementioned accommodation space 11 of what, and this top supporting part 21 tops are sincere to wear within mouthfuls 13 on the sidewall aforementioned, and the other end of this axostylus axostyle 2 is provided with an access slot 22 again;

One needle body 5 is plugged in aforementioned plugging in the hole 211, and passes and aforementionedly wear mouthfuls 13, and the appropriate position of this needle body 5 is also configurable a limited block 6;

One elastic body 3 is set on the aforementioned axostylus axostyle 2, and establish on the aforementioned top supporting part 21 of what on one end top, and this elastic body 3 can be a compression spring;

One backstop 4 has a hollow channel 41, and this passage 41 wears for aforementioned axostylus axostyle 2, and the aforementioned joint of packing what mouthful 12 places, and the one end is the stop section 42 of little caliber and aforementioned elastic body 3 is only done to support;

In this way, can make these needle body 5 nationalitys make elastic displacement, and become an easy probe structure by being configured in body 1 interior holding of elastic body 3.

Fig. 4 is an action synoptic diagram of the present utility model, as shown in the figure: the probe sleeve pipe of the utility model, be that sharp what uses on vacuum suction formula anchor clamps 7, because of its vacuum fixture 7 utilizes an exhaust tube (not shown) that is connected on the pedestal 71, extracting air is so that form a vacuum state in the vacuum fixture 7, nationality is by atmospheric pressure, and being pressed down with needle body 5, loam cake 72 contacts, needle body 5 is presses down shape, and but 6 pairs of needle bodies of nationality limited block 5 are done the restriction of a reduction length, lead 8 at nationality configuration what axostylus axostyle 2 one ends is sent to numerical value on the main frame (not shown), to reach test purpose to be measured; After test is finished, will charge into gas again in this vacuum fixture 7, loam cake 72 is risen, this moment needle body 5 with nationality by the retroaction of elastic body 3 pop into position.

The structural improvement of the relevant a kind of pin spy of the utility model system, the utility model nationality is made this needle body nationality in body make elastic displacement by elastic body, and is become an easy probe structure by simple and easy structure.

A kind of probe structure of the utility model, mainly be configured in the backstop that body engages mouthful by the axostylus axostyle in a body, the sheathed what body, elastic body and on the sheathed what axostylus axostyle, take this elastic body is supported, and be plugged with a needle body with detection effect on the axostylus axostyle, this needle body also passes the mouth that wears of this body other end, becomes an easy probe.The utility model was forgone the shortcoming of known probe already fully.The above only is the preferred embodiment of the utility model, when can not with qualification protection domain of the present utility model, promptly the equalization of doing according to the utility model generally changes and revises, and all should still belong to the protection domain of the utility model patent.
