At the same time, the connector 5 is constrained by a positioning cone sleeve 6, and the shunt sleeve 2 limits the positioning cone sleeve 6. The stability of the installation of the connector 5 can be effectively ensured by cooperating with a limiting disk 7. Loosening the limiting disk 7 also facilitates the positioning cone sleeve 6 to be pulled out from the shunt sleeve 2, thereby improving the convenience of the device during wiring. The specific structural arrangement of the assembly is as follows;

[0024] The connection assembly includes a shunt sleeve 2 arranged at one end of a restraint sleeve 1, the restraint sleeve 1 is connected to the shunt sleeve 2, and a wiring harness 3 is arranged in the restraint sleeve 1;
