Abstract

The utility model relates to a probe box, comprising a box, a probe, a spiral spring, and an insulating partition sheet. The insulating partition sheet is disposed on a side in the box. One end of the spiral spring is connected with a surface of the insulating partition sheet, and the other end is connected with a side in the box opposite to the insulating partition sheet. The probe is disposed on the other surface of the insulating partition sheet and extends out of the box. The spiral spring is used in the probe box to provide elastic forces for the probe, so elastic forces are larger and resilience is better. The spring is not easy to lose efficacy or damage, so the spring is more durable. Even though the spiral spring loses efficacy or is damaged, when changing the spring, the insulating partition sheet is pressed on the probe, an end of the spiral spring is installed on the other surface of the insulating partition sheet, and the other end of the spiral spring is connected in the box, so changing is very simple.

Description

Probe box

Technical field

The utility model relates to electric variable measurement field, particularly relates to a kind of probe box.

Background technology

The probe structure of traditional probe box is that each root probe is all connected with a curve spring, guarantees that every probe has certain elastic force.

Yet the recovery of curve spring is poor, slightly excessively deformation will be replied completely, easily loses efficacy, as long as and this probe box structure has a spring damage (or elastic force dies down) will cause whole equipment to use.

Utility model content

Based on this, be necessary to provide preferably probe box of a kind of permanance.

A kind of probe box, comprise box body and probe, also comprise helical type spring and insulating spacer, described insulating spacer is installed on the side in described box body, one side, the other end that described helical type spring one end is connected to described insulating spacer is connected to a side relative with described insulating spacer in described box body, and described probe is located on the another side of described insulating spacer and is extend out to outside box body.

In an embodiment, also comprise and from box body, penetrate in box body and the wire being electrically connected to described probe therein.

Therein in an embodiment, the length under described helical type spring non-stress state is greater than the described insulating spacer that is installed in box body to the distance of the relative side of box body.

In an embodiment, the quantity of described probe is 4 therein.

Above-mentioned probe box adopts helical type spring for probe provides elastic force, with respect to conventional art, is the scheme that each root probe is all equipped with a curve spring, and elastic force is larger, recovery is better, be difficult for losing efficacy or damaging, so more durable.Probe box of the present utility model, be more than the twice of conventional art the serviceable life of its spring.Even and helical type spring failure or damage, while changing spring, only insulating spacer need to be pressed on probe, helical type spring one end is arranged on insulating spacer another side, and the other end of helical type spring is connected in box body, changes very simple.

Accompanying drawing explanation

Fig. 1 is the inner structure schematic diagram of an embodiment middle probe box.

Embodiment

For the purpose of this utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

It should be noted that, when element is called as " being fixed on " another element, can directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may have centering elements simultaneously.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement are just for illustrative purposes.

Unless otherwise defined, all technology of using are herein identical with the implication that belongs to the common understanding of those skilled in the art of the present utility model with scientific terminology.The term using in instructions of the present utility model herein, just in order to describe the object of specific embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.

Fig. 1 is the inner structure schematic diagram of an embodiment middle probe box, and probe box comprises box body (Fig. 1 does not show), probe 10, insulating spacer 20 and helical type spring 30.Insulating spacer 20 is installed on the side in box body, is bottom side in Fig. 1.One side (in Fig. 1 one side) upward, the other end that helical type spring 30 1 ends are connected to insulating spacer 20 are connected to a side relative with insulating spacer 20, i.e. top side in Fig. 1 in box body.Probe 10 is located at the another side (in Fig. 1 one side) down of insulating spacer and is gone up and extend out to outside box body.Insulating spacer 20 separates helical type spring 30 and probe 10, avoids probe 10 short circuits.

Above-mentioned probe box adopts helical type spring 30 for probe 10 provides elastic force, with respect to conventional art, is the scheme that each root probe is all equipped with a curve spring, and elastic force is larger, recovery is better, be difficult for losing efficacy or damaging, so more durable.Probe box of the present utility model, be more than the twice of conventional art the serviceable life of its spring.Even and if helical type spring 30 lost efficacy or damaged, while changing spring, only insulating spacer 20 need to be pressed on probe 10, helical type spring 30 one end are arranged on insulating spacer 20 another sides, and the other end of helical type spring 30 is connected in box body, changes very simple.And conventional art need to enter curve spring fitting in corresponding pilot hole, because the difficulty that space in box is less so change is larger.

In the embodiment shown in fig. 1, the quantity of probe 10 is 4.In other embodiments, probe box structure of the present utility model also can be used in conjunction with the probe groups of other number of probes.

Box body can adopt plastic material, need to be on box body perforate to penetrate the wire for being electrically connected to probe 10.

In a preferred embodiment, the length that needs choose reasonable helical type spring 30, make the length under helical type spring 30 non-stress states be greater than insulating spacer 20 to the distance of a box body side relative with insulating spacer 20, installing rear helical type spring 30 should be in compressive state.But helical type spring 30 is also unsuitable compressed too many, to guarantee that probe 10 has suitable shrink space.

The quantity of middle helical type spring 30 embodiment illustrated in fig. 1 is 1, understandable, and the helical type spring 30 that is greater than also can be set in other embodiments abreast, so that stronger elastic force to be provided, and further improves reliability.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
