Embodiment Construction

[0022] Such as Figure 1 to Figure 5 As shown, the plug 20 of the embodiment of the present invention is cylindrical as a whole, and the front and rear ends are the plug-in end and the terminal respectively. The plug includes a cylindrical plug housing 1 and a connecting cap set on the outer periphery of the plug housing 1 2. Both the plug housing 1 and the connecting cap 2 are made of metal. The plug housing 1 is equipped with a plug insulator 14 of insulating material. A plurality of guide keys 8 extending in the axial direction are provided on the outer peripheral surface near the front end of the plug housing 1, and three curved grooves 5 extending backward from the front end of the connecting cap are opened on the inner wall of the connecting cap 2, each On the inner wall of the connection cap 2 near the end of the curved groove 5, there is a staple hole 12 through the connection cap 2 for the staple on the socket housing to snap in. A color band 15 for identification is...

Abstract

The invention discloses a lock type sealing electrical connector for a curved groove, comprising a plug and a socket, wherein the plug comprises a plug shell and a connecting cap which is rotatably sleeved on the periphery of the plug shell; a seal ring for seal fit with the end surface of the plug shell is arranged in the socket; one end of the seal ring opposite to the plug-in direction of the plug is provided with one annular end surface supported against the socket; the annular end surface is provided with an annular groove which is annularly distributed; the plug shell is in rigid thrust fit with the connecting cap in an axial direction through two axially manually supported structures arranged at front and back positions on opposite surfaces of the plug and the connecting cap; and a connecting cap delaying transmission friction surface, a shell friction surface, a plastic cushion ring, and a delaying transmission spring are connected between the plug shell and the connecting cap. In the invention, the plug shell and the connecting cap do not need to move opposite to the axial direction through changing the structure of the seal ring, thereby avoiding the failure problem of sealing and having no influence on locking design and locking operation.

Description

technical field [0001] The present invention relates to electrical connectors. Background technique [0002] Such as Figure 11 As shown, the existing type of sealed electrical connector adopts a three-curve groove buckle connection structure, which requires that after the contacts in the plug and the corresponding contacts in the socket are connected in place, the connection between the plug shell and the socket shell should be ensured at the same time. Locking and sealing, which requires the end face of the plug housing 41 to press the sealing ring 50 in the compression socket 51, and at the same time, the staple holes on the inner surface of the connecting cap 42 carried by the plug housing 41 can be displaced to the outer wall of the socket housing. The position of the staple on the top allows the staple to slide into the staple hole just along the groove line of the three-curve groove 44. In order to facilitate the above-mentioned fitting in place and compression of th...
