Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a conductive terminal and a battery holder. Background Art

[0002] The battery holder, also known as the battery holder connector, is used to load batteries and is generally welded to the PCB board. The battery holder includes a base and a conductive terminal. The installation methods of the conductive terminal on the base include snap-in, interference fit and injection molding. Both the snap-in and interference fit methods are to first manufacture the base and the conductive terminal, and then assemble the two after the base and the conductive terminal are completed. The connection stability is low and the conductive terminal is prone to loosening. The injection molding method is to use an injection process to cover the bending part of the conductive terminal with insulating material. After the insulating material is cured, a base is formed. The bending part of the conductive terminal and the base restrict each other's movement in multiple directions, which can greatly improve the connection stability between the conductive terminal and the base. Therefore, in application environments where higher requirements are placed on the connection stability between the conductive terminal and the base, a battery holder obtained by injection molding is required.

[0003] The bent portion has a blocking and limiting function. When the insulating material is injection-molded onto the bent portion of the conductive terminal, some gas on the top wall of the bent portion cannot be discharged in time during the injection molding process. At the same time, some insulating materials also generate some gas during the curing process. Such gas will also accumulate on the top wall of the bent portion, causing hollowing and affecting the connection stability between the conductive terminal and the base. Utility Model Content
