The invention relates to a junction device for electrical tests and particularly provides an auxiliary junction pole for the electrical test on 35 kV equipment. The auxiliary junction pole solves the problem in the prior art that people must frequently climb on electrically charged equipment to conduct the wiring test on 35 kV equipment. According to the technical scheme of the invention, the auxiliary junction pole comprises an insulated operation tube and a wiring clip. An insulated pull rod passes through the interior of the operation tube. A tooth bar is fixedly arranged on one side of the pull rod. The lower end of the operation tube is fixedly provided with a handle frame and a deflector rod is hinged inside the frame. The deflector rod is fixedly provided with a holding rod. A stepped plunger is penetrated through the lower end of the operation tube. The middle part of the plunger is provided with a waist-shaped hole. One end of the inner side of the hole is matched with the tooth bar. The upper end of the insulated pull rod is hinged to a clamping jaw. A connecting rod passes through the lower frame of the wiring clip. The upper end of the connecting rod is fixedly provided with a lower jaw. The outer side of a vertical frame is provided with a binding post. The lower end of the connecting rod is fixedly provided with a connecting sheet. The auxiliary junction pole is simple in operation and people no longer need to climb up any more. Meanwhile, the auxiliary junction pole is safe and reliable, wherein a wiring clip and an operation rod can be disconnected. Moreover, the auxiliary junction pole is good in applicability and is applicable to the wiring process of leading-out ends in various tests. In addition, the auxiliary junction pole is good in contact performance and an oxide film at a test point can be clamped broken by the lower jaw.
