Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of Chinese Patent Application No. 201711007228.3 filed on October 25, 2017 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.

Field of the Invention

[0002] Embodiments of the present disclosure relate to an assembly system, particularly, to an assembly system adapted to insert leads into a housing.

Description of the Related Art

[0003] In the technical field of manufacturing a connector, it is desired generally to insert a first lead and a second lead into a housing from both sides of the housing, respectively, and then to solder ends of the inserted first lead and second lead together. In order to ensure the soldering quality, the ends of the inserted first lead and second lead must be aligned and contacted with each other.

[0004] In the relevant art, the operation of inserting the first lead and the second lead is usually performed manually. Generally, the worker needs to insert the first lead into the housing, and then insert the second lead into the housing. However, during inserting the second lead, the first lead that has been inserted into the housing tends to move. This causes the inserted first lead tending to be offset from its precise installation position, and may intervene and hinder the insertion of the second lead. Thus, such an arrangement decreases the efficiency of inserting the leads, and lowers the quality of the product.
