Description

Tooth high power battery probe body in a kind of tooth

Technical field

The utility model is related to field of electrical components, tooth high power battery probe body in more particularly to a kind of tooth.

Background technology

The tooth Shape Design of the electric current pin of traditional high current probe is all tetrahedral pyramidal shape, and its tooth Shape Design is non- The often class pin design of point, its object is to can puncture the oxide layer of battery pole.And Battery formation, the charge and discharge of present battery industry Electric current is increasing；Battery electrode column reduces instead due to being limited to amplify be subject to its structure.

The electrode terminal of diminution causes traditional high current probe when to battery charging and discharging, without most enough big contacts Area, it is impossible to probe housing be made to keep the area that preferably conducts electricity with battery electrode column well.

It needs to increase the pressing strength of probe housing if increasing it by force and contacting conductive area, makes it deeper to be pierced into Battery electrode column is can to increase contact area, but the consequence so brought is to give battery electrode column one very deep puneture, to pole There is a great harm for column.

Utility model content

The utility model is to solve the above problems, provide tooth high power battery probe body in a kind of tooth, in increase contact Battery electrode column is not injured in the case of area, while more preferably heat dissipation effect can also be played in high current transmission process.

The utility model can also combination voltage test probe, the transmission of realization electric current and the one progress of voltage tester.

In order to achieve the above objectives, the technical solution adopted in the utility model is：Tooth high power battery probe master in a kind of tooth Body, including probe bodies, probe bodies are followed successively by probe face, spring fixed end and rear end face from front to back, and probe face is equipped with Multiple contact jaws, contact jaw are that the upper surface area milled out is less than the pyramid suspended deck structure of lower face area, and upper surface On be milled with V-type groove in the same direction, and form linear teeth at upper surface edge；

Further, probe bodies inner hollow, and it is reserved with circular through hole on probe face.

Further, spring fixed end point diameter is slightly larger and is milled with twice groove.

Utility model works principle and its advantage are as follows：

When probe bodies touch determinand, a surface contact force is formed between contact jaw and determinand, specifically, line Property tooth and determinand pole between form a surface contact force, after the oxide layer that pole surface layer is scratched by linear teeth, the line Property tooth contacted as line contact surface with pole, achieve the effect that high current transmit.

It is well known that the electric current that different conducting sectional areas can transmit is different, conducting sectional area is bigger, transmission Electric current it is bigger, the heat in electric current transmission process distributes also can be preferable, and the conducting area in this structure is punctured with linear teeth After oxide layer with pole contact area calculate, more traditional probe structure, under identical compression distance, using compression distance as 0.1mm differs only in linear teeth and pointed tooth to calculate, and the conducting sectional area of this structure is 0.15mm², and traditional structure is led Logical sectional area is 0.034mm², therefore linear teeth, under conditions of equally depth is pierced into, contact area is bigger than conventional probe structure, So as to which the electric current of transmission is bigger.

Meanwhile in crown intensity, linear teeth is high compared with traditional structure intensity height, long lifespan, abrasion resistance.

And in high current transmission process, probe bodies can unquestionable generation heat, spring fixed end point diameter Slightly mostly as heat dissipation region, twice groove is milled with, the heat dissipation area of probe bodies can be increased, reaches preferably heat dissipation effect Fruit.

In conclusion the utility model has the following advantages that：

1st, linear teeth can in the case that realize it is smaller to battery electrode column injury increase contact area, ensure electric current transmission Effect.

2nd, the relatively traditional tip-like contact jaw of linear teeth, contact area bigger is not easy to wear, and intensity is high, service life It is long.

3rd, probe bodies inner hollow reserves circular through hole on probe face, can combination voltage test probe, realize electric current Transmission and the one progress of voltage tester.

4th, probe bodies are milled with twice groove, can increase the heat dissipation area of probe bodies, reach preferably heat dissipation effect.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments：

Embodiment 1：

Tooth high power battery probe body in a kind of tooth, as shown in Figure 1, probe bodies 1 are followed successively by probe from front to back Face 11, spring fixed end 12 and rear end face 13,1 inner hollow of probe bodies, and circular through hole 14 is reserved on probe face 1, Voltage tester probe can be loaded in this probe bodies 1, the integrated design of electric current and voltage probe, spring fixed end 12 are realized Point diameter is slightly larger and is milled with twice groove 121, specifically, in high current transmission process, probe bodies 1 can be unquestionable Heat is generated, 12 point diameter of spring fixed end slightly mostly as heat dissipation region, is milled with twice groove 121, can increase spy The heat dissipation area of pin body 1 reaches preferably heat dissipation effect.

With further reference to attached drawing 1 and with reference to attached drawing 2, probe face 11 is equipped with multiple contact jaws 2, and contact jaw 2 mills out 21 area of upper surface is less than the pyramid suspended deck structure of 22 area of lower face, and is milled with V-type groove 23 on upper surface 21 in the same direction, And form linear teeth 3 at 21 edge of upper surface.

With reference to detection process, when probe bodies 1 touch determinand, a surface is formed between contact jaw 2 and determinand Specifically, forming a surface contact force between linear teeth 3 and the pole of determinand, pole table is scratched by linear teeth for contact force After the oxide layer of layer, which contacts as line contact surface with pole, achievees the effect that high current is transmitted.

At this it is noted that this structure type is toothing in tooth, i.e., first it is milled with the contact jaw 2 of quintar shape, then Thereon linear teeth 3 is milled out on end face 21.
