Abstract

The invention relates to a sealing type double coaxial contact which includes a pin assembly and a jack assembly. The pin assembly includes a first bracing ring, a rear sleeve, a pin body and a first cable. The jack assembly includes an outer jack, a second bracing ring and a second cable. The pin body is inserted to the outer jack, and the height of a second insulator is lower than that of an end surface of the outer jack. An inserting end of the second insulator is provided with a guide fillet. According to the invention, the contact is advantaged in that the pin body of the pin assembly is inserted to the outer jack of the jack assembly and the height of the second insulator is lower than that of the end surface of the outer jack, such that the pin assembly and the jack assembly cooperates with each other so as to bring the outer jack and the pin assembly into contact, and excellent effects of guiding is provided upon connection; the guide fillet on the second insulator further increases guiding property upon connection, so that the contact achieves multi-layer and hierarchical guiding of connection, has excellent guiding property; and the pin body and the outer jack cooperate so as to enable the contact to have sealing property.

Description

technical field [0001] The invention relates to a contact piece, in particular to a sealed double coaxial contact piece. Background technique [0002] At present, the contacts used for signal transmission are mainly coaxial contacts, and the contact parts of each layer are positioned and fixed by mechanical methods such as crimping. In special occasions with sealing performance requirements, the structure of this form of assembly of loose parts has no sealing function and cannot meet the requirements of use. At the same time, the contact has weak links in terms of insulator guidance and other aspects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cylindrical sealing ring structure to solve the problems of poor sealing performance and poor guiding performance of existing contact parts. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical so...
