In this embodiment, the sub-interface 200 can be plugged with the main interface 110, so as to realize electrical connection.
The conductive part 300 is used to electrically connect the circuit board body 100 and the sub-interface 200, thereby completing the electrical connection between the sub-interface 200 and the circuit board body 100.
The conductive part 300 comprises a first fixing part 310, a second fixing part 320 and a flexible conductive ring 330 arranged between the first fixing part 310 and the second fixing part 320, wherein a coating cavity 311 is arranged in the first fixing part 310, and one end of the flexible conductive ring 330 extends into the coating cavity 311. The first fixing piece 310 and the second fixing piece 320 are both annular, the coating cavity 311 is an annular cavity, and one end of the coating cavity 311, which is close to the inner ring of the first fixing piece 310, is provided with an oil coating port 312; one end of the coating cavity 311 close to the flexible conductive ring 330 is provided with a squeezing port 313. One end of the flexible conductive ring 330 is provided with a rubber ball 331, wherein the size of the rubber ball 331 is larger than that of the extrusion opening 313.

In the installation process of the flexible conductive ring 330, if an artificial installation mode is adopted, the first fixing part 310 is artificially extruded, the center of the conductive part 300 is sunken due to the flexible line, and the flexible conductive ring 330 has elasticity, so that the first fixing part 310 is artificially extruded, the flexible line can sunken toward the center of the conductive part 300, the force cannot be well transmitted to the second fixing part 320, and the clamping groove 321 and the clamping ring 230 in the connecting channel 210 cannot be clamped. In this embodiment, the inner core 111 is inserted into the flexible conductive ring 330, because the first fixing element 310 is limited in the connecting channel 210 by the fixing ring 410, and the inner core 111 is inserted into the flexible conductive ring 330, the flexible wire cannot recess toward the center of the conductive part 300, and the inner core 111 occupies the space where the flexible wire deforms, so that the force can only be transmitted to the second fixing element 320, and finally, the clamping of the clamping groove 321 and the clamping ring 230 in the connecting channel 210 is realized.
The working principle is as follows: when the connector 500 needs to be electrically connected to the circuit board body 100, the resilient piece 533 is pressed, the female terminal 510 is inserted into the fixing cavity 122 from the through hole 124, and the mounting block 531 of the female terminal 510 slides in the sliding cavity until the sliding cannot be continued. At this time, the elastic piece 533 is released, and the elastic piece 533 is bounced up and clamped in the U-shaped clamping block 121.
When the female head 510 needs to be taken out, the elastic piece 533 only needs to be pressed lightly, and since the elastic piece 533 is obliquely arranged on the rotation stop plate, a gap exists between the elastic piece 533 and the mounting block 531, the elastic piece 533 can be pressed, so that the elastic piece 533 is separated from the U-shaped fixture block 121, and the female head 510 is taken out.
When the sub-interface 200 needs to be plugged into the main interface 110 of the circuit board body 100 to complete the electrical connection between the sub-interface 200 and the main interface 110, the flexible conductive ring 330 is first placed into the connection channel 210, and then the fixing ring 410 is mounted into the mounting groove 340, and the sub-interface 200 is inserted into the main interface 110.
When the sub-interface 200 is plugged into the female interface 110, the inner core 111 is inserted into the flexible conductive ring 330, and since the flexible conductive ring 330 is formed by surrounding a plurality of arc-shaped flexible wires, as shown in fig. 8(b), the flexible wires are recessed toward the center of the conductive part 300, the inner core 111 presses and expands the flexible conductive ring 330, and the flexible conductive ring 330 also plays a role in buffering, and the flexible conductive ring 330 extends to two sides, i.e., the direction of F in the figure. The flexible conductive ring 330 is provided with one end with a rubber ball 331, the coating cavity 311 is extruded, vaseline in the coating cavity 311 is extruded to the oiling port 312 and flows out of the oiling port 312, the inner core 111 continuously extrudes and props up the flexible conductive ring 330 as the inner core 111 continuously moves towards the direction of the second fixing piece 320, the flexible conductive ring 330 continuously extends towards the two ends, and the vaseline is continuously extruded out, so that the vaseline is coated on the inner core 111 to finish the coating of the vaseline, and the functions of corrosion prevention and oxidation prevention are achieved. One end of the flexible conductive ring 330, which is far away from the rubber ball 331, continuously presses the second fixing element 320, because the second fixing element 320 is in the connecting channel 210, the second fixing element 320 can only move along the axial direction of the connecting channel 210, the second fixing element 320 is provided with a clamping groove 321, and the connecting channel 210 is internally provided with a clamping ring 230, so that during the moving process of the second fixing element 320, the clamping ring 230 can be clamped with the clamping groove 321, and the axial movement of the conductive part 300 is completed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
