Embodiment Construction

[0023] Embodiment 1 of the underwater plug connector of the present invention, such as figure 1 As shown, the connector takes the front end as the plug-in end, and includes a housing 11, an insulator 12, a vulcanized body 13, and a contact piece 15 connected with a wire 14. In this embodiment, the housing 11 is in the shape of a cylinder with two ends open. , the front end of the inner hole forms a stepped hole with a large front and a small rear, and a positioning step surface facing forward is formed between the large and small diameter sections of the stepped hole. The outer contour of the insulator 12 is a stepped shaft shape with a large front and a small rear, which includes The large-diameter section located at the front end and the small-diameter section located at the rear end form a mating stepped surface facing backwards between the large-diameter section of the insulator 12 and the small-diameter section. Complementary, its front end is also provided with a valgus ...

Abstract

The invention relates to the field of electric connectors, in particular to an underwater plug-pull connector and a preparation method thereof, wherein the underwater plug-pull connector can be applied to the seafloor and other deepwater environments. The front end of the connector serves as a plug end, the connector comprises a shell, an insulator, a sulfide body and a contact piece connected with a conducting wire, and the contact piece, the insulator and the shell are fixed together in a vulcanization mode through the sulfide body. A locating step surface facing the front is installed inside the shell, a matching step surface which is in check fit with the locating step surface is installed on the outer circumferential surface of the insulator, the contact piece is installed inside an installation hole of the insulator in a plug-in mode, the rear side of the insulator is fixedly connected with a supporting piece, and an air exhaust gap is formed between the supporting piece and the inner wall surface of the shell. The fact that the insulator has enough strength to bear vulcanization injection force can be guaranteed through the supporting piece, and meanwhile, the air exhaust gap is formed between the supporting piece and the inner wall surface of the shell, so that during a vulcanization process, air inside the shell can be exhausted from the rear end of the shell through the air exhaust gap, and therefore, the problem that seal of an existing underwater plug-pull connector is not reliable is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an underwater plug-in connector applicable to deep water environments such as seabeds and a manufacturing method thereof. Background technique [0002] At present, in the field of electrical connectors, electrical connectors with underwater plugging and unplugging functions require that each contact should be isolated after the product is mated in a deep water environment to avoid short circuits. However, hard materials are difficult to deform, so they cannot meet the requirements of the system. Therefore, most products in the prior art adopt rubber vulcanization molding structures. [0003] The Chinese patent No. 200910304515.X discloses a socket, which is a kind of underwater plug connector, which includes a socket housing, a socket insulator and a socket vulcanized body, and a set of sockets is axially pierced on the socket insulator Socket contact, the front end of the s...
