Description

Technical Field

[0001] The utility model relates to the field of electronic connectors, in particular to a double-jointed female connector. Background Art

[0002] Current female connectors, such as Figure 1 and Figure 2 As shown, two spring slots 311 are provided on the upper inner wall of the outer body 310, and two circular springs 320 are clamped in the corresponding spring slots 311. The lantern spring 330 is insulated and fixedly installed on the inner side of the outer body 310 below the circular spring 320 through a first insulating ring 340 and a second insulating ring 350 made of plastic. The tail top ring 360 is fixedly inserted on the lower inner side of the outer body 310 and is electrically connected to the outer body 310. The top of the tail top ring 360 and the bottom of the second insulating ring 350 abut against each other, thereby preventing the lantern spring, the first insulating ring 340 and the second insulating ring 350 from falling. The two ends of the first local circuit are connected to the two poles of the female connector (i.e., the circular spring 320 and the lantern spring 330) through the two poles of the external male connector, and the second local circuit is connected to the two poles of the female connector through two connecting wires (one end of one connecting wire is connected to the lower end of the tail top ring 360, and one end of the other connecting wire passes through the tail top ring 360 and the second insulating ring 350 from bottom to top and connects to the lantern spring 330), thereby connecting the two ends of the first local circuit to the two ends of the second local circuit respectively. On the one hand, the connection steps of the two connecting wires are relatively cumbersome. On the other hand, when the external male connector is inserted and pulled up and down in the lantern spring 330, the first insulating ring 340 has a certain plasticity. When the lantern spring 330 bulges outward, the first insulating ring 340 will be deformed and cause the lantern spring 330 to shift, thereby increasing the wear of the lantern spring 330 and the first insulating ring 340, affecting the service life of the entire female connector.
