The size of mounting groove 340 is unanimous with the size of solid fixed ring 410, and when sub-interface 200 and female interface 110 joint, solid fixed ring 410's one end supports female interface 110 inner wall, and the other end supports step face 420 to gu fixed ring 410 has also been restricted in mounting groove 340. 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 120 is inserted into the flexible conductive ring 330, and since the first fixing element 310 is limited in the connecting channel 210 by the fixing ring 410, the inner core 120 is inserted into the flexible conductive ring 330, so that the flexible wire cannot recess toward the center of the conductive part 300, and the inner core 120 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 groove 321 is clamped with the collar 230 in the connecting channel 210.
The working principle is as follows: when an external element needs to be conducted with the circuit board body 100, the connector 500 is inserted into the bottom plate 130 of the circuit board body 100, the back surface of the flexible ratchet 521 plays a guiding role, the connector 500 is inserted into the circuit board body 100 along the back of the flexible ratchet 521, and the front surface of the flexible ratchet 521 abuts against the circuit board body 100, so that the connector 500 cannot be easily taken out. When the distance from the lead 550 to the component on the circuit board body 100 needs to be adjusted, the lead post 540 is rotated, so that the lead post 540 moves along the length direction of the lead post 540, the length of the lead 550 extending out of the fixing frame 510 is adjusted, and the connection distance between the lead 550 and the component on the circuit board body 100 is finally adjusted.
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.
As shown in fig. 9(b), when the sub-interface 200 is plugged into the female interface 110, the inner core 120 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, the flexible wires are recessed toward the center of the conductive part 300, the inner core 120 presses and stretches 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., in the direction F in fig. 9 (b). The flexible conductive ring 330 is provided with one end with a rubber ball head 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 120 continuously extrudes and props up the flexible conductive ring 330 as the inner core 120 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 120, the coating of the vaseline is completed, and the effects of corrosion prevention and oxidation prevention are achieved. One end of the flexible conductive ring 330, which is far away from the rubber ball head 331, continuously presses the second fixing piece 320, because the second fixing piece 320 is in the connecting channel 210, the second fixing piece 320 can only move along the axial direction of the connecting channel 210, the second fixing piece 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 piece 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.
