[0002] A connector, also known as a plug-in unit, is an electronic device mainly used to connect two active devices to transmit current. The connector consists of two plug connectors that are inserted into each other. One of the plug connectors is installed with jack terminals, which is called the female plug, and the other plug connector is installed with blade (or pin) terminals, which is called the male plug. The disadvantages of the jack terminals traditionally used in connector plugs are as follows: 1. The socket has no or poor tension, and the mating with the blade terminals is a rigid plugging and unplugging, which not only has a poor plugging and unplugging feel, but also has problems such as being too tight during the initial plugging and unplugging and being too loose during the later plugging and unplugging; 2. The barb in the jack terminal does not have an unlocking function. When the blade terminal is forcibly pulled out, the wear on the barb is very large, resulting in the barb being prone to failure during the second plugging. Content of the Utility Model
