Accuracy.
Utility model content
The purpose of the utility model is to provide a kind of spring needles, and when with to avoid carrying out overcurrent test, electric current is all passed through
The problem of crossing spring.
In order to achieve the above object, the technical solution adopted by the present invention is that, a kind of spring needle, including needle tubing and needle shaft, institute
It states one end of needle tubing and one end sliding of the needle shaft and is interference fitted.
The technical solution of the utility model also has the following characteristics that
The needle shaft is located in the needle tubing, and the outer diameter of the needle shaft is not less than the internal diameter of the needle tubing, the needle
Compressed spring is additionally provided in pipe, one end of the compressed spring can then be withstood on the needle shaft.
Ring-shaped step is provided in the needle shaft, one end of the compressed spring is withstood on the ring-shaped step.
The needle tubing and the needle shaft slide and are provided with multiple strip-shaped holes on the outer wall of the end of interference fit, and needle shaft is stretched
When entering the end, which can carry out the expansion deformation of elasticity.
The needle shaft protrudes on the outer wall of the end of the needle tubing and is provided with multiple strip-shaped holes, which protrudes into the needle tubing
When can carry out elasticity expansion deformation.
The surface of the needle tubing, the needle shaft and the compressed spring is gold-plated.
It is tested for overcurrent.
The utility model has the beneficial effects that electric current can be through when the spring needle using the utility model carries out overcurrent test
Needle tubing, needle shaft and compressed spring are transmitted, and impedance is relatively stable, can be played a very good protection to spring needle, thus
Ensure the accuracy of test result.

Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Embodiment 1
As shown in Figure 1, a kind of spring needle, is made of needle tubing 1 and needle shaft 3, wherein one end of one end of needle tubing 1 and needle shaft 3
Sliding and interference fit, i.e., one end of needle tubing 1 is closely packed together with needle shaft 3.Specifically, needle shaft 3 is located in needle tubing 1, and
The outer diameter of needle shaft 3 is not less than the internal diameter of needle tubing 1, is additionally provided with compressed spring 2 in needle tubing 1, one end of compressed spring 2 withstands on needle shaft
On 3.Ring-shaped step is provided in needle shaft 3, one end of compressed spring 2 is withstood on ring-shaped step.As shown in Fig. 2, needle tubing 1 and needle shaft
Multiple strip-shaped holes are offered on 3 slidings and the outer wall of the end of interference fit, it, should when design can make needle shaft 3 protrude into the end in this way
End can carry out the expansion deformation of elasticity.
The spring needle is tested for overcurrent, and the axis along needle tubing 1 is slotted on the outer wall of one end, equably set
Multiple strip-shaped holes are set, the end of needle tubing 1 can be easier to deform when the insertion of one end of needle shaft 3, the outer wall meeting of this hour hand axle 3
It is in close contact between the inner wall of needle tubing 1, in this way when carrying out overcurrent test, electric current can be through needle tubing 1, needle shaft 3 and compression bullet
Spring 2 is transmitted, and impedance is relatively stable, can be played a very good protection to spring needle, so that it is guaranteed that the standard of test result
True property.When the end of needle shaft 3 touches tested electric elements, certain sliding occurs between meeting and needle tubing 1, makes to compress
Spring 2 is compressed, and after test, compressed spring 2, which restores deformation, to be made to reset again between needle shaft 3 and needle tubing 1.
Embodiment 2
As shown in Figure 1, a kind of spring needle, is made of needle tubing 1 and needle shaft 3, wherein one end of one end of needle tubing 1 and needle shaft 3
Sliding and interference fit, i.e., one end of needle tubing 1 is closely packed together with needle shaft 3.Specifically, needle shaft 3 is located in needle tubing 1, and
The outer diameter of needle shaft 3 is not less than the internal diameter of needle tubing 1, is additionally provided with compressed spring 2 in needle tubing 1, one end of compressed spring 2 withstands on needle shaft
On 3.Ring-shaped step is provided in needle shaft 3, one end of compressed spring 2 is withstood on ring-shaped step.Needle shaft 3 protrudes into the end of needle tubing 1
