Assembly and encapsulation method of high-frequency elongate contact piece with cable

Abstract

The invention relates to an assembly and encapsulation method of a high-frequency elongate contact piece with a cable. The assembly and encapsulation method comprises the following steps of opening an encapsulation hole with a diameter slightly smaller than the maximum diameter of an encapsulation needle head in an outer-layer metal body above a part needed to be encapsulated of an electrical connector by 1-2 millimeters; assembling the cable and the electrical connector to form a high-frequency contact piece which is not sealed; inclining the high-frequency contact piece at an angle of 45 degrees, hermetically connecting the encapsulation needle head and the encapsulation hole of the electrical connector, and performing pressurization and encapsulation until an adhesive liquid overflows out of a tail press part of the high-frequency contact piece; and vertically placing and curing the high-frequency contact piece, wherein a part of adhesive liquid overflows out of the encapsulation hole. The technical operation and method is practical, and reliable encapsulation of the elongate contact piece which is automatically sealed, has high reliable electrical performance and is provided with the cable is achieved.

Description

technical field [0001] The invention relates to a method for assembling and sealing slender high-frequency contacts with cables, belonging to the field of element filling and sealing. Background technique [0002] Electrical performance and sealing performance are routine assessment items in electrical connectors. With the rapid development of high-tech and high-reliability weapons, new and higher requirements are put forward for electrical connectors, such as: having high-reliability electrical performance and A special electrical connector with sealing performance. This kind of electrical connector has harsh service conditions, high environmental resistance requirements, and high reliability requirements. [0003] Taking the general electrical connector as an example, the general electrical connector is mainly composed of three parts: the shell, the insulator, and the low-frequency contact piece. The sealing of the electrical connector is mainly made of potting rubber to e...

Problems solved by technology

[0005] The general glue filling method is open filling, with a large space, and the glue filling needle can easily extend into the bottom of the glue filling layer of the electrical connector, so that the glue liquid slowly fills the glue filling layer from the bottom

However, high-frequency contacts with cables have a small structure, narrow filling space, difficult needle insertion, high potting difficulty, and low product qualification rate; the method of first injecting glue and then assembling has poor assembly quality and poor glue filling quality. , insulation resistance, withstand voltage performance cannot be guaranteed, etc.
