[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0023] Embodiment 1: Refer to Figs. 1-3 The utility model provides a high temperature resistant POGOPIN spring needle, which is applied in the field of spring needle technology, comprising a needle tube 1, a needle head 2 slidingly arranged in the needle tube 1, and a spring 3 fixed between the needle tube 1 and the needle head 2. A containing gap is formed between the needle tube 1 and the needle head 2, and the spring 3 is arranged in the containing gap to provide elastic support for the needle head 2. A set of heat dissipation components are arranged in the needle head 2, which are used to quickly dissipate the heat in the containing gap to improve the high temperature working capacity of the spring needle.
[0024] The heat dissipation components comprise a communication groove 5 arranged in the needle head 2, and a plurality of exhaust grooves 4 arranged in the needle head 2 and communicated with the communication groove 5. The exhaust grooves 4 are evenly distributed on the surface of the needle head 2 to form heat dissipation channels, which are helpful to quickly discharge the heat in the containing gap.
[0025] In addition, the device further comprises a limiting component, which comprises a limiting ring 6 arranged on the upper side of the needle tube 1 and used to limit the needle head 2 to prevent the needle head 2 from sliding out of the needle tube 1.
[0026] The connecting mode of the limiting ring 6 and the needle tube 1 is improved in the embodiment. An external thread is arranged on the surface of the limiting ring 6, and an internal thread is arranged in the needle tube 1, so that the limiting ring 6 is connected to the needle tube 1 through the threads. This connecting mode is stable and reliable, and is convenient for installation and disassembly.
[0027] The limiting ring 6 is inversely convex, and the radius of the upper side is greater than that of the needle tube 1, so that the limiting ring 6 has an end point when being screwed, and stops moving after reaching the end point.
[0028] The limiting ring 6 is further improved in the embodiment. A screw ring 7 is fixed to the surface of the limiting ring 6, which can increase the friction between the limiting ring 6 and the needle tube 1 to improve the stability of the connection. At the same time, the screw ring 7 can also play a buffering role to reduce the impact of the needle head 2 on the limiting ring 6 during sliding.
[0029] Preferably, the limiting ring 6 and the screw ring 7 are both made of polyethylene. Polyethylene material has good insulation performance and high temperature resistance, which can ensure the normal work of the limiting ring 6 and the screw ring 7 in a high temperature environment.
[0030] Embodiment 2: Refer to Figs. 1-3 On the basis of embodiment 1, the needle tube 1 is improved in the embodiment. A guide column 8 is fixed in the needle tube 1, which is used to limit the spring 3 to prevent the spring 3 from deviating or twisting in the containing gap. The arrangement of the guide column 8 can improve the working stability of the spring 3 and prolong the service life of the spring needle.
[0031] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
