Waterproof electric connector

Abstract

The utility model discloses a waterproof electric connector which comprises a connector female end and a connector male end, and the surface of a sealing ring is in contact with a jack. Through the design of structures such as a second rubber ring, an extrusion ring, a sealing ring and a positioning block, after the locking nut is installed on the female end socket in a threaded mode, the second rubber ring can seal the locking nut and the female end socket, so that the sealing effect between the locking nut and the female end socket is improved, and through cooperation of the extrusion ring, the sealing ring and the positioning block, the sealing effect between the locking nut and the female end socket is improved. When the locking nut is installed on the female-end socket in a threaded mode, the positioning block can push the extrusion ring, so that the sealing ring can be extruded to deform, and the sealing ring is tightly attached to the inner wall of the jack due to deformation, and therefore the space between the female-end socket and the male-end plug can be sealed, the sealing effect between the female-end socket and the male-end plug can be improved, and the service life of the female-end socket and the male-end plug can be prolonged. The probability of short circuit damage of the electric connector caused by corrosion of water in the locking nut can be reduced, and the service life of the electric connector can be prolonged.

A joint screw hole is opened on the front surface of the electrical connector joint, and a screw hole waterproof ring is fixedly connected to the inner side wall of the joint screw hole. For this new type of waterproof electrical connector, through the mutual cooperation of the connecting wire waterproof ring, the screw hole waterproof ring, the joint connection waterproof ring, the slot, the sleeve, the internal thread of the sleeve, the waterproof annular ring, the sleeve locking block, the external thread of the joint, the groove, the connector waterproof ring, and the pin waterproof layer, the overall waterproof effect of the new type of waterproof electrical connector can be achieved, so that the new type of waterproof electrical connector can be used in a water-related environment, protecting the normal operation of the circuit and the equipment, and effectively protecting people's property safety and life safety.

[0004] However, there are still some problems in the actual operation of the above new type of waterproof electrical connector. For example, during the long-term use of the sleeve in water, the water will gradually corrode the sleeve, affecting the sealing effect of the sleeve, causing water to contact the electrical connector head through the gap of the sleeve, resulting in a short circuit and damage to the electrical connector head. Therefore, we need to propose a waterproof electrical connector. Content of the Utility Model

[0027] It should be noted that by the positioning block 11 abutting against the side of a set of extrusion rings 8, the extrusion rings 8 and the sealing rings 9 can be pushed, so that the extrusion rings 8 can extrude the sealing rings 9, causing the sealing rings 9 to deform under extrusion and closely adhere to the inner wall of the jack 14 due to the deformation, thereby improving the sealing effect between the female socket 4 and the male plug 3.

[0028] In an optional embodiment: an installation groove 15 is provided on the male plug 3. The extrusion rings 8 and the sealing rings 9 are both arranged in the installation groove 15.

[0029] It should be noted that the installation groove 15 can play a role in positioning the extrusion rings 8 and the sealing rings 9, and can prevent the extrusion rings 8 and the sealing rings 9 from falling off the female socket 4.

[0030] In an optional embodiment: two groups of positioning grooves 10 that are relatively adapted to the positioning blocks 11 are symmetrically provided on the side of the male plug 3.
