[0002] Wiring terminals are gradually widely used in various fields, including signal terminals, power terminals, connection terminals, etc., and are connection ends in circuits. Terminals are components that connect a storage battery to an external conductor. Their main functions are to transmit electrical signals or conduct electricity. In electrical engineering, terminals mostly refer to wiring terminals, also called connection terminals, and their types include single-hole, double-hole, socket, hook, etc. In terms of materials, they are copper plated with silver, copper plated with zinc, copper, aluminum, iron, etc.

[0003] In the household boiler manufacturing industry, a large number of quick-insert terminals are required inside household boilers to connect the inside of the equipment to the grounding of the metal shell. During traditional wire harness assembly production, workers hold the quick-insert terminals in one hand and the grounding tab in the other hand, and manually insert the quick-insert terminals onto the grounding tab by exerting force.

[0004] However, since the insertion resistance between the quick-insert terminal and the grounding tab is greater than 50 N, it is time-consuming and laborious for workers to insert the quick-insert terminal into the grounding tab. The installation efficiency of the quick-insert terminal is low, and after long-term work, the hands of workers will become fatigued or even damaged, affecting the subsequent installation quality and efficiency of the quick-insert terminal. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above-mentioned defects existing in the prior art and provide an assembly tool for pneumatic quick-insert terminals and grounding tabs.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] An assembly tool for pneumatic quick-insert terminals and grounding tabs, comprising a fixed plate, a telescopic cylinder, a pressing head and a positioning block. The telescopic cylinder and the positioning block are fixed on the fixed plate, and the telescopic cylinder is drivingly connected to the pressing head;
