Direct-plug water-sealed connector component, plug thereof and socket thereof

Abstract

The invention relates to a direct-plug water-sealed connector component, a plug thereof and a socket thereof. The connector component comprises a plug shell and a plug insulator which are connected together; a group of pin contact pieces are axially arranged on the plug insulator; a plug vulcanized body covers the front end and surrounding wall of the plug insulator through vulcanization; the rear end of the plug vulcanized body extends to seal and cover the front end of the plug shell; the pin contact pieces are fixed into a whole through the vulcanization by the plug vulcanized body; the parts, exposed from the plug vulcanized body, of the pin contact pieces form pin plug-in connection sections; the parts, close to the plug vulcanized body, of the pin plug-in connection sections are covered by a corresponding vulcanized protrusion extended from the front end of the vulcanized body to form vulcanized plug-in connection sections; the parts, on the front end of the vulcanized plug-in connection sections, of the pin plug-in connection sections are bare pug-in connection sections; the diameter of the bare pug-in connection sections is smaller than that of the vulcanized plug-in connection sections; and a plug-in connection guide part is arranged at the surface joint part of the bare pug-in connection sections and the vulcanized plug-in connection sections. The connector component can be plugged directly in water.

Description

technical field [0001] The invention relates to a water-tight connector assembly and its plug and socket used in deep water environment. Background technique [0002] At present, most of the water-sealed connector assemblies suitable for deep water environments use the plug structure and the supporting socket structure to axially fix the corresponding insulator and insulating pressure plate in the axial through hole of the shell, and the corresponding contact piece axially It is installed in the insulator and the insulating pressure plate. When the plug and socket are plugged together, the plug shell and the socket shell are partially overlapped and mated together. For example, the underwater sealed direct plug-in pull plug disclosed in Chinese patent ZL200620138111. The plug and socket of the de-separated electrical connector, the deep-water self-separated electrical connector disclosed in Chinese patent ZL200720033820.6, all belong to this type of electrical connector.

Problems solved by technology

In order to realize the water seal of this kind of electrical connector, sealing rings are required to be installed between the shell and the insulator and between the insulator and the contact, which will inevitably lead to an increase in the radial profile size of the plug and socket, and the plug shell and socket The male-female mating structure provided on the shell further increases the radial profile size of the plug and socket, making the overall volume of the plug and socket larger after mating. Under the trend of miniaturization of electronic products and equipment, the above-mentioned The structural electrical connector cannot adapt to the small installation space

In addition, sealing in the form of a sealing ring, the contacts and contact mounting holes, insulators and insulator mounting holes must achieve high precision, which will inevitably increase processing difficulty and cost
