Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a single PIN bending mechanism for a plug. Background Art

[0002] The plug is also called a connector, which includes plastic parts and PIN pins. The PIN pin is a metal material used in the connector to complete the conductive transmission of electrical signals. The connector is a device used to connect two active devices to transmit current or signals.

[0003] As electronic components are becoming smaller and more sophisticated, there are often certain restrictions on the total height of the product. Therefore, more and more PIN pins on connectors need to be bent.

[0004] However, the bending structure of the prior art is to bend the PIN first and then use a pin insertion machine to perform the pin insertion operation, which will cause inconvenience to the transportation of the PIN. The direction of the PIN needs to be distinguished during the transportation of the bent PIN. If the PIN is first inserted into the plastic part and then bent, this problem can be solved. However, after the PIN is inserted into the plastic part, during the transportation and feeding process, the PIN may be skewed and the skewed direction is opposite to the bending direction, making it impossible to perform the bending operation. For this reason, we propose a single PIN bending mechanism for the plug. Utility Model Content
