Description
Technical Field
[0001] The utility model relates to the technical field of watertight electric connectors, in particular to a quick-plug watertight electric connector. Background Art
[0002] The watertight electrical connector is mainly composed of a watertight plug and a watertight socket. The watertight plug and the watertight socket can be quickly connected and quickly disconnected by plugging and unplugging. When connecting two sets of cables, the watertight electrical connector can be used as an auxiliary. The watertight electrical connector has functions such as waterproofing and can meet the needs of underwater cable laying.
[0003] After the watertight plug and the watertight socket are connected by plugging, the connection between them can be reinforced by a threaded device arranged on their outer walls. However, under this connection method, the threaded devices are also easily affected by external forces and become disconnected, affecting the stable connection between the watertight plug and the watertight socket.
[0004] The main reason for the above problems is that the connection of the threaded device is mainly achieved by rotating a group of threaded parts in one direction, so that the threaded teeth on the inner wall of one group of threaded parts are threadedly connected with the threaded teeth on the outer wall of another group of threaded parts. However, when the threaded parts are rotated in the opposite direction, the two groups of threaded parts will be separated. When the connected watertight electrical connector is laid underwater with the cable, it will be affected by the underwater environment. For example, the flow of water carrying underwater materials constantly contacts the threaded device arranged on the outer wall of the watertight electrical connector. Over a long period of time, the stability of the connection between the two groups of threaded parts will be affected. To address the above problems, we propose a quick-plug watertight electrical connector. Utility Model Content

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] The utility model embodiment discloses a quick plug-in and pull-out watertight electrical connector.
[0028] According to the attached Figure 1-6 As shown, it includes a watertight plug 1, a watertight socket 2 plugged into the watertight plug 1, and a threaded seat 3 and a threaded shell 301 for locking the watertight plug 1 and the watertight socket 2. The threaded seat 3 is fixedly connected to the outer wall of the watertight plug 1, and the outer wall of the threaded seat 3 is threadedly connected to the inner wall of the threaded shell 301. The watertight plug 1 and the watertight socket 2 form a watertight electrical connector. The watertight plug 1 and the watertight socket 2 are quickly connected and quickly disconnected by plugging and unplugging. When connecting two groups of cables, the watertight electrical connector can be used, and the watertight electrical connector has functions such as waterproofing, which can meet the needs of underwater cable laying.
[0029] The inner wall of the threaded casing 301 is provided with a limiting mechanism for limiting the rotation direction of the threaded casing 301, that is, the threaded casing 301 is rotated in one direction so that the threaded casing 301 is threadedly connected with the threaded seat 3, and then the limiting mechanism is provided so that when the threaded casing 301 is rotated in the opposite direction, the threaded casing 301 will not rotate, thereby making the threaded casing 301 and the threaded seat 3 stably connected, ensuring the stable connection between the watertight plug 1 and the watertight socket 2. The limiting mechanism includes a ratchet 401, and the ratchet 401 and the threaded casing are connected. The inner wall of the shell 301 is fixedly connected, the outer wall of the ratchet 401 does not contact the outer wall of the watertight socket 2, the ratchet 403 is clamped with the outer wall of the ratchet 401, one end of the ratchet 403 is rotatably connected to the outer wall of the watertight socket 2, the outer wall of the watertight socket 2 is fixedly connected with a sealing ring 302, the support screw 402 is rotatably set on one side of the sealing ring 302, one end of the ratchet 403 is fixedly connected to the outer wall of the support screw 402, a torsion spring 404 is set between one side of the sealing ring 302 and the outer wall of the ratchet 403, and the torsion spring 404 is used to drive the elastic reset of the ratchet 403.
[0030] The outer wall of the sealing ring 302 is fixedly connected with a bearing 303, and the outer wall of the bearing 303 is fixedly connected to the inner wall of the threaded casing 301. Through the setting of the bearing 303, when the threaded casing 301 is rotated, the threaded casing 301 and the watertight socket 2 always maintain a connection state.
[0031] The support screw 402 and the locking nut 405 are threadedly connected with each other, and the ratchet 403 and the watertight socket 2 are locked through the threaded connection between the support screw 402 and the locking nut 405.

The locking nut 405 is set, and the support screw 402 and the sealing ring 302 can be locked, so that the setting position of the ratchet 403 is locked.
[0032] The quick-plug watertight electrical connector has a one-way transmission device arranged between the inner wall of the threaded casing 301 and the outer wall of the watertight socket 2. When the threaded casing 301 is rotated in one direction, the threaded casing 301 can be threadedly connected with the threaded seat 3 arranged on the outer wall of the watertight plug 1. However, when the threaded casing 301 is rotated in the opposite direction, the threaded casing 301 will not rotate, thereby achieving a stable connection between the threaded casing 301 and the threaded seat 3, ensuring a stable connection between the watertight plug 1 and the watertight socket 2 in the plugged state.
