Description

Technical Field

[0001] This utility model belongs to the field of electronic pin technology, specifically relating to a composite contact pin assembly and its electronic components. Background Technology

[0002] Pins are used in electronic components to connect circuit boards, modules or other electronic components. They are typically used to transmit signals, power or data and play a key role in the assembly and maintenance of electronic equipment. Their materials are usually copper alloys or gold-plated, silver-plated or other materials to ensure good conductivity and corrosion resistance. The housing of the pin is usually made of plastic or ceramic materials to provide insulation protection and mechanical support.

[0003] Existing electronic pins mostly adopt a single-end rigid straight-insertion structure. After long-term use, due to insufficient pin contact pressure, poor pin contact occurs, resulting in unstable signals in electronic devices. To address this, we propose a composite contact pin assembly and its electronic components. Utility Model Content

[0004] The purpose of this invention is to provide a composite contact pin assembly and its electronic components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite contact type pin assembly, comprising,

[0006] A pin base is disposed at the male terminal of an electronic component;

[0007] A spring guide rod assembly is elastically limited on the pin base, and the spring guide rod assembly can move elastically along the axial direction of the pin base;

[0008] Two spring contact end assemblies are provided, which are symmetrically arranged on the spring guide rod assembly, and the spring contact end assemblies can move elastically along the axial direction of the spring guide rod assembly.

[0009] Preferably, the insert base has a first limiting and moving cavity inside, and the lower limiting and guiding part of the spring guide rod assembly is disposed in the first limiting and moving cavity;

[0011] Preferably, the spring guide rod assembly includes a limiting guide rod, an annular guide end, and a first spring;

[0012] The limiting guide rod is positioned within the first limiting moving cavity, with its upper end extending into the guide ring groove. The annular guide end is positioned within the guide ring groove at the upper end of the limiting guide rod. A first spring is positioned between the bottom of the annular guide end and the bottom of the guide ring groove on the limiting guide rod.

[0013] Preferably, the lower guide movement of the spring contact end assembly is disposed inside the limiting guide rod, and the upper guide movement of the spring contact end assembly is disposed inside the annular guide end.

[0014] Preferably, a second limiting moving cavity is formed inside the limiting guide rod corresponding to the bottom of the inner side of the annular guide end, and the lower limiting guide of the spring contact end assembly is arranged in the second limiting moving cavity.

[0015] Preferably, the spring contact end assembly includes a limiting guide moving rod, a contact end, and a second spring;

[0016] The lower limiting guide rod is disposed in the second limiting moving cavity, the upper part of the limiting guide rod extends to the inner side of the annular guide end, the contact end is disposed on the limiting guide rod corresponding to the inner side of the annular guide end, and the second spring is disposed on the limiting guide rod between the bottom of the contact end and the bottom of the inner side of the annular guide end.

[0018] An electronic component including a composite contact pin assembly.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention includes a spring guide rod assembly and a spring contact end assembly. When the pin assembly is in use, both the first and second springs are in a naturally extended state, causing the limiting guide rod and the limiting guide moving rod to be in an extended state. When the pin assembly is inserted into the socket, the two contact ends first contact the inside of the socket. At this time, the contact ends, through the second spring, elastically guide the limiting guide moving rod towards the second limiting moving cavity. Then, the limiting guide rod is further pushed, causing the annular guide end, through the first spring, to elastically guide the limiting guide rod towards the first limiting moving cavity, thus allowing the pin assembly to be fully inserted into the socket and locked in place by a latch. At this time, the first and second springs are in a compressed state, causing the limiting guide rod and the limiting guide moving rod to apply pressure towards the socket, thereby completely abutting the contact ends against the inside of the socket. This ensures the pressure applied to the pin assembly, guaranteeing the stability and reliability of the pin assembly's insertion connection. Furthermore, the use of two contact ends allows for individual elastic contact, ensuring the composite contact connection of the pin assembly and guaranteeing the signal transmission stability of the pin assembly.
