Abstract

The utility model discloses a 180 degree slidingtype butt joint 3-5A heavy current spring needle, including the needle tubing that has the inner chamber, connect slidable steel ball and piston from top to bottom in the needle tubing, the base is connected to needle tubing one end, the piston pass through the spring with the base is connected. The steel ball is used as a sliding connection medium, the steel ball can rotate to offset the lateral force generated by butt joint of more than 90 degrees, and the inclined surface structure piston below the steel ball can enable the steel ball, the piston and the needle tube to be better combined to avoid the risk that the current passes through the spring when the whole spring needle is in an overlarge current state, so that the structure is simple and the practicability is high.

Description

180-degree sliding type butt joint 3-5A high-current spring needle

Technical Field

The utility model relates to a spring needle technical field specifically is 180 degrees slidingtype butt joints 3-5A heavy current spring needles.

Background

The spring needle is a precision connector applied to electronic products such as mobile phones and the like, is widely applied to semiconductor equipment and plays a role in connection. The shape is different according to the application, but the inside of the whole body is provided with a precise spring structure. At present, spring needles on the market are butted by a needle shaft moving up and down by 90 degrees, when a product structure needs to be butted at an angle of 90 degrees to 180 degrees, the needle tube is easy to damage, the service life cannot meet the requirement, and the current cannot be too large.

Disclosure of Invention

In order to overcome the deficiency of the prior art scheme, the utility model provides a 180 degree slidingtype butt joint 3-5A heavy current spring needle can the effectual problem that the solution background art provided.

The utility model provides a technical scheme that its technical problem adopted is:

the 180-degree sliding type butt joint 3-5A high-current spring needle comprises a needle tube with an inner cavity, wherein a steel ball and a piston which can slide are connected up and down are arranged in the needle tube, one end of the needle tube is connected with a base, and the piston is connected with the base through a spring.

Further, the piston is a cylinder with an oblique section, wherein the oblique section of the piston is connected with the steel ball.

Furthermore, the center of the bottom of the piston is fixedly connected with a bottom column, and the bottom column vertically penetrates into the spring.

Furthermore, one end of the interior of the needle tube, which is connected with the base, is of an inverted triangular structure and extends to the center of the base.

Furthermore, the outer diameter of one end, connected with the base, of the needle tube is larger than that of the other end of the needle tube.

Furthermore, a ring body is arranged at one end, close to the base, of the surface layer of the needle tube, and one end, close to the base, of the ring body is larger than the other end of the ring body.

Furthermore, the central position of the bottom of the base is fixedly connected with a tail needle.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a steel ball can rotate through steel ball itself as the sliding connection medium, offsets because of receiving the yawing force that the butt joint produced more than 90 degrees, and inclined plane structure piston under it then enables steel ball, piston and needle tubing and can better combine to avoid whole spring needle when too big electric current, the electric current is through the risk of spring, simple structure, the practicality is strong.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figure 1, the utility model provides a 180 degree slidingtype butt joint 3-5A heavy current spring needle, including the needle tubing 1 that has the inner chamber, connect slidable steel ball 2 and piston 3 from top to bottom in the needle tubing 1, base 4 is connected to needle tubing 1 one end, piston 3 pass through spring 5 with base 4 connects.

The piston 3 is a truncated cylinder, wherein the oblique section of the piston 3 is connected with the steel ball 2; a bottom column 6 is fixedly connected to the center of the bottom of the piston 3, and the bottom column 6 vertically penetrates into the spring 5; one end of the needle tube 1, which is connected with the base 4, is of an inverted triangle structure and extends to the center of the base 4; the outer diameter of one end of the needle tube 1 connected with the base 4 is larger than that of the other end; a ring body 7 is arranged at one end of the surface layer of the needle tube 1 close to the base 4, and one end of the ring body 7 close to the base 4 is larger than the other end; the central position of the bottom of the base 4 is fixedly connected with a tail needle 8.

It explains that need supplement, the utility model discloses a 180 degree slidingtype butt joint 3-5A heavy current spring needle, be equipped with gliding steel ball 2 and piston 3 from top to bottom in the needle tubing 1, the spring 5 of reconnection bottom, under spring 5's effort, steel ball 2 and piston 3 can freely slide downwards, and simultaneously, utilize steel ball 2 can free rotation as the medium, can offset the yawing force because of receiving the butt joint more than 90 degrees and producing simultaneously, combine the piston 3 of inclined plane structure simultaneously, can make steel ball 2, piston 3 and needle tubing 1 better cooperation, can avoid whole spring needle electric current when too big electric current through the risk of spring. In order to prevent the piston 3 from deviating in the operation process, the bottom pillar 6 is additionally arranged at the bottom of the piston 3 and extends to the center of the spring 5, and meanwhile, the base 4 and the tail needle 8 can play a good role in fixing the whole body, so that the whole operation is convenient.
