[0011] Preferably, the third insulator and the second insulator are arranged perpendicular to each other at 90 degrees, and the position where the third insulator and the second insulator are connected is set as an inclined plane, and the inclined planes are spliced ​​with each other.

[0012] Preferably, an internal thread is arranged inside the end of the screw sleeve away from the first shell, and an external thread is arranged at one end of the second shell, and the internal thread and the external thread are connected to realize the connection between the plug and the socket.

[0013] Beneficial effects of the utility model:

[0014] This structure effectively reduces the size of the connector connection space, and the second shell is set to a 90-degree bent structure, which is convenient for connection in a right-angle area, making the connector more versatile in use.

The third insulator 203 and the second insulator 204 are fixedly installed inside the second shell 201, and the socket 202 is fixedly installed inside the third insulator 203 and the second insulator 204.

[0027] Further, a groove 108 is provided at the part where the screw sleeve 107 and the first housing 101 are sleeved, and a snap ring 109 is installed inside the groove 108. The groove 108 is distributed outside the first housing 101 and inside the screw sleeve 107, and the end face of the groove 108 is rectangular and has an annular structure. The snap ring 109 is installed in the groove 108 to fix the screw sleeve 107 and the first housing 101, and the snap ring 109 is an open annular elastic structure.

[0028] Furthermore, a sealing ring 103 is sleeved on the outer side of one end of the first housing 101 on which the threaded sleeve 107 is sleeved. The sealing ring 103 performs waterproof sealing on the connection part between the plug 1 and the socket 2.

[0029] Furthermore, the second housing 201 is a 90-degree bent structure, so that the connectors can be conveniently connected vertically in space, and the connectors can be conveniently connected in a right-angle area compared to horizontal connections on both sides.
