[0005] To achieve the above-mentioned purpose, a new type of 35KV cold-shrink outdoor cable terminal is provided, including: a device body and a fixed sleeve, the side wall of the fixed sleeve is provided with a rotating part, the side wall of the fixed sleeve is fixedly connected to two mounting plates, the side walls of the two mounting plates are rotatably connected with a connecting member, the side wall of the connecting member is fixedly connected with a positioning rod, the side wall of the fixed sleeve is fixedly connected to two vertical plates, the external thread of the positioning rod is connected with a fixing nut, the fixing sleeve is fitted with the connecting sleeve and the outside of the device body, and the positioning rod is matched with the fixing nut, so as to fix the connection between the connecting sleeve and the device body to avoid damage after long-term use.

[0006] A cable is arranged in the middle of the device body, a connecting sleeve is arranged at one end of the device body, and a wiring terminal is arranged at one end of the connecting sleeve.

[0007] A support plate is fixedly connected between the two vertical plates, springs are arranged in the middle of the two vertical plates, one end of the two springs is fixedly connected to the limiting plate, and the side walls of the two limiting plates are fixedly connected to the clamping blocks.

[0008] The two side walls of the clamping block are both arranged in an arc shape, and the two side walls of the clamping block are both fitted with the outer side of the positioning rod.

[0009] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention.

[0010] The purpose of this utility model is to provide a new type of 35KV cold shrink outdoor cable terminal, the main innovations are:

[0011] The utility model arranges a fixing sleeve outside the connecting sleeve and the device body, and uses the fixing sleeve to fix the connecting sleeve, thereby avoiding damage caused by long-term use of fixing with adhesive tape. Fixing with the fixing sleeve can increase the service life. BRIEF DESCRIPTION OF THE DRAWINGS
