Description

Technical Field

[0001] This utility model relates to the field of electronic components, and in particular to a high-strength female connector. Background Technology

[0002] Current female connectors, such as Figure 1 As shown, a spring slot 211 is provided on the upper inner sidewall of the outer casing 210. A circular spring 220 is secured in the spring slot 211. A lantern spring 230 is nested within a first insulating ring 240 made of plastic and is fixedly installed on the inner side of the outer casing 210 below the circular spring 220 in conjunction with a second insulating ring 250. A tail top ring 260 is fixedly inserted into the lower inner side of the outer casing 210 and is electrically connected to the outer casing 210. The top of the tail top ring 260 abuts against the bottom of the second insulating ring 250, thereby preventing the lantern spring 230, the first insulating ring 240, and the second insulating ring 250 from falling off. The two ends of the first partial circuit are connected to the two poles of the female connector (i.e., the circular spring 220 and the lantern spring 230) respectively through the two poles of the external male and female connectors. The second partial circuit is connected to the two poles of the female connector through two output wires (one output wire is connected to the lower end of the tail top ring 260, and the other output wire passes through the tail top ring 260 and the second insulating ring 250 from bottom to top and connects to the lantern spring). Thus, the two ends of the first partial circuit are connected to the two ends of the second partial circuit respectively. When the external male connector is inserted and removed from the lantern spring 230, the first insulating ring 240 has a certain plasticity. When the lantern spring 230 bulges outward, it will cause the first insulating ring 240 to deform and cause the lantern spring 230 to shift, thereby increasing the wear of the lantern spring 230 and the first insulating ring 240 and affecting the service life of the entire female connector.

The upper inner wall of the outer shell is radially recessed outward to form an annular spring mounting groove, in which the annular spring is installed. The top of the lantern spring insert has a lantern spring mounting groove with the same outer diameter as the lantern spring, in which the lantern spring is installed. The upper part of the inner wall of the outer sleeve is radially recessed outward to form an outer sleeve mounting groove with the same outer diameter as the lower part of the lantern spring insert. The lower part of the lantern spring insert is fixedly inserted into the outer sleeve mounting groove. The inner side of the outer shell... A housing mounting cavity is formed by a radial outward recess below the annular spring, which matches the outer diameter of the upper part of the outer sleeve. The washer is installed in the housing mounting cavity and abuts against the inner top wall of the housing mounting cavity. The upper part of the outer sleeve is fixedly inserted into the housing mounting cavity. The lantern spring and the lantern spring insert are both located below the washer. The top of the lantern spring or the top of the lantern spring insert abuts against the bottom of the washer. An insulating gap is formed between the outer diameter of the lantern spring insert and the inner wall of the housing mounting cavity. The end cap is fixedly sleeved outside the outer wall of the lower part of the outer sleeve, and the outer wall of the end cap abuts against the inner wall of the housing. The center hole of the outer sleeve and the center hole of the end cap are connected to form a wiring through hole. The upper end of the wiring through hole is connected to the bottom of the lantern spring insert.

[0005] Preferably, the end cap includes an end cap body and a plurality of insert arms protruding upward from the outer side of the inner ring of the end cap body. The outer side wall of the lower part of the outer sleeve is recessed inward to form a slot corresponding to the insert arms. The insert arms are inserted into the slots. The outer wall of the end cap body abuts against the inner side wall of the outer shell.

[0006] Preferably, the lower part of the inner sidewall of the outer shell slopes outward from top to bottom to form a pressing surface, and the outer wall of the end cap body abuts against the pressing surface.

[0007] Preferably, there are two annular springs, and correspondingly, there are also two annular spring mounting slots, with the annular springs installed in the corresponding annular spring mounting slots.

[0008] Preferably, the bottom of the lantern spring mounting groove is recessed in the middle to form an inner process groove, and the bottom of the lantern spring rests on the lantern spring mounting groove outside the inner process groove.
