Description

Technical Field

[0001] The utility model relates to the technical field of FAKRA connectors, in particular to a plastic shell tooling for inserting FAKRA wires. Background Art

[0002] At present, FAKRA has become a general standard radio frequency connector in the automotive industry and is widely used in the industry for in-vehicle wireless signal transmission and camera video signal transmission. In response to market demand, the production efficiency and quality requirements for the FAKRA product line are also increasing day by day. After the daily equipment processing of the FAKRA wire, it still needs to be manually assembled with a plastic shell before it can be finally completed. The assembly method is that an employee holds the plastic shell in one hand and the FAKRA wire in the other hand to perform the shell insertion action. Repeating this action for a long time cannot ensure that the shell is inserted in place, and there is a probability of the PIN being withdrawn.

[0003] At present, such an operation method cannot prevent the situation of PIN withdrawal, resulting in rework, increased labor and raw material scrap costs, affecting production efficiency and increasing quality risks. Based on the above defects and deficiencies, it is necessary to improve the existing technology and design a plastic shell tooling for inserting FAKRA wires. Summary of the Utility Model
