Description
Technical field
It the utility model is related to a kind of precision connector, more particularly to a kind of spring probe.
Background technology
Spring probe, also known as Pogo pin, alternatively referred to as probe, thimble are a kind of applied to mobile phone, computer, intelligent hand
Precision connector in the electronic products such as table, at present spring probe be mainly made up of three parts, respectively needle shaft, helical spring
And needle tubing, needle shaft are integrated with needle tubing riveted, spring is contained in needle tubing and is squeezed between needle shaft and needle tubing so that needle shaft
Being capable of axial stretching.Needle tubing is usually integral structure, gold-plated using stainless steel or brass, and stainless steel contact resistance is big, copper plating
Gold is not corrosion-resistant, and needle tubing can cause spring probe easily to occur in charging process because being corroded by sweat or other materials often
It is electrolysed bad phenomenon.
Thus, it is necessary to a kind of new spring probe is designed to solve above-mentioned technical problem.
Utility model content
The purpose of this utility model is the provision of a kind of spring probe for having and reducing contact resistance.
To realize object defined above, the utility model adopts the following technical scheme that：A kind of spring probe, it includes needle shaft, pin
Pipe and spring, described needle shaft one end are contained in needle tubing, and the other end stretches out needle tubing, and the spring is contained in needle shaft, and the spring is visited
Pin is additionally provided with the insert for being embedded in needle tubing bottom surface, and the insert is using gold or palladium material.
As further improvement of the utility model, the insert is circular pie, wide at the top and narrow at the bottom.
As further improvement of the utility model, the bottom surface of the insert and needle tubing is coplanar.
As further improvement of the utility model, the needle tubing uses stainless steel.
As further improvement of the utility model, the spring probe also includes the ball being contained in needle tubing, described
Ball is clamped between needle shaft and spring, and the spring is squeezed between ball and needle tubing.
As further improvement of the utility model, the ball uses the gold-plated material of stainless steel.
As further improvement of the utility model, the needle shaft is provided with the inclined plane for compressing ball.
The utility model spring probe is additionally provided with the insert for being embedded in needle tubing bottom surface, and the insert uses gold or palladium material,
Gold or palladium material easily turn on, and reduce contact resistance, improve the application function of spring probe.

Fig. 1 is the schematic perspective view of the utility model spring probe.
Fig. 2 is the schematic perspective view of another angle of the utility model spring probe.
Fig. 3 is the sectional view of the utility model spring probe.
Fig. 4 is the three-dimensional exploded view of the utility model spring probe.
Embodiment
Refer to shown in Fig. 1 to Fig. 4, the utility model spring probe 10 includes needle shaft 11, spring 12, needle tubing 13, ball
14 and insert 15.Needle shaft 11 uses the gold-plated material of brass, and needle tubing 13 uses stainless steel, corrosion-resistant, and ball 14 is using stainless
The gold-plated material of steel.
Spring 12 is installed in inside needle tubing 13 with ball 14, and needle tubing 13 is sheathed on outside needle shaft 11, and one end of needle shaft 11 is stretched
Go out needle tubing 13, be connected, be squeezed between ball 14 and needle tubing 13 with ball 14 by spring 12 between needle shaft 11 and needle tubing 13, circle
Ball 14 is clamped between needle shaft 11 and spring 12, and needle shaft 11 is provided with the inclined plane 110 compressed with ball 14, it is ensured that needle shaft
11 and needle tubing 13 be steadily contacted, so as to ensure that the transmission of the electric current between needle shaft 11 and needle tubing 13 is stable.
The bottom surface of needle tubing 13 is provided with recess 131, and insert 15 is embedded in recess 131, and needle tubing 13 and the bottom surface of insert 15 are coplanar.
Insert 15 is reduced contact resistance, is improved the application function of spring probe 10 using gold or palladium material, easily conducting.Insert 15 is circular
Pie structure, it is wide at the top and narrow at the bottom.
Although being example purpose, preferred embodiment of the present utility model, the common skill of this area are had been disclosed for
Art personnel will realize the situation of the scope of the utility model and spirit disclosed in not departing from by appended claims
Under, various improvement, increase and substitution are possible.
