Variable-diameter hole contact element and contact element assembly using same

Abstract

The invention relates to the field of electrical connectors, and particularly relates to a variable-diameter hole contact element which can be matched with pins of various external diameters in use and a contact element assembly using the same. The variable-diameter hole contact element comprises a sheath and a conductive sleeve assembled in the sheath. The front end of the sheath is used as a plugging end. The wall of the conductive sleeve is provided with a spring pawl of which the front end is disposed on the wall of the conductive sleeve and the rear end is gradually close to the center line of the conductive sleeve from front to back. The wall of the conductive sleeve of the variable-diameter hole contact element is provided with the spring pawl, the front end of the spring pawl is disposed on the wall of the conductive sleeve, and the rear end of the spring pawl is gradually close to the center line of the conductive sleeve from front to back. Therefore, the hole contact element can be matched with a matching pin contact element through the spring pawl of the hole contact element to switch on a circuit. The spring pawl can reliably contact the pin contact element as long as the pin contact element is plugged into the conductive sleeve. The variable-diameter hole contact element can be matched with pin contact elements of various external diameters in use.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a variable-diameter hole contact that can be used in conjunction with pins of various outer diameters and a contact component using the hole contact. Background technique [0002] In recent years, with the rapid development of communication, electrical and other industries, the application fields of electrical connectors are also being continuously expanded. As the core components of electrical connectors, contact components are gradually becoming more diversified. [0003] The contact assembly is composed of matching pin contacts and socket contacts. When in use, one of the pin contacts and socket contacts is assembled in the plug housing, and the other is assembled in the socket In the housing, along with the mating and separation of the plug and the socket, the contact assembly completes the conduction and disconnection of the circuit. [0004] In the traditional contact ...

AI Technical Summary

Problems solved by technology

In order to ensure reliable contact and conductive connection between the pin and the socket, the size of the pin end matched with the socket has very strict requirements, and the tolerance usually does not exceed 0.1mm, otherwise there will be pin contact Insufficient insertion and withdrawal force (too small outer diameter of the pin contact) or failure to fit (too large outer diameter of the pin contact) between the socket and the socket contact, which will lead to the problem that the electrical signal cannot be transmitted. This problem is particularly prominent in RF coaxial connectors that require high-quality transmission signals

[0005] In order to avoid the above problems, when the types of multiple pin contacts used at the same electrical fracture are different, it is necessary to equip socket contacts of corresponding sizes according to the different specifications of the pin contacts, which results in the same There are more connectors at the position, and when the size difference of the contact components of different specifications is small, it is also very easy to cause confusion.
