The positions of the pins 5 can be exchanged, the pins 5 at the first position and the third position slide into the transfer groove 41 at the same time, then slide along the same direction, when the pins abut against other cables, other cables are pulled downwards, the pins can penetrate through the space between the cables and the bottom of the transfer groove until the pins 5 at the first position are aligned with the sliding grooves 42 where the pins 5 at the original third position are positioned, the pins slide in, and then the pins 5 at the third position slide into the sliding grooves 42 where the pins 5 at the original first position are positioned, so that the exchange of the pins 5 at the first position and the pins 5 at the third position is realized; similarly, the second pin 5 and the sixth pin 5 can also be exchanged, and at this time, the flat cable mode of the plug 2 changes, and the plug 2 can be freely switched between the two flat cable modes 568A and 568B, so that the connection mode of the plug 2 and the socket 1 is changed, and the cross lines are changed into the parallel lines, or the parallel lines are changed into the cross lines.

Example one

Referring to fig. 4, the diameter of the end of the pin 5 facing away from the socket 1 (see fig. 2) is smaller than the width of the bottom of the sliding slot 42, the side wall of the sliding slot 42 facing away from the transfer slot 41 is fixedly provided with an elastic bump 43, and the thickness of the elastic bump 43 is larger than the difference between the diameter of the pin 5 and the width of the sliding slot 42. When the pin 5 slides to the end of the sliding groove 42, it abuts against the elastic lug 43, and at this time, the pin 5 slides forcefully to extrude the elastic lug 43, and the elastic lug 43 deforms under the stress, so that the pin 5 can pass through, and is blocked when sliding back.

The implementation principle of the above embodiment is as follows:

the positions of the pins 5 are adjusted according to the required wire arrangement mode, then the plug 2 is inserted into the socket 1, one end of the plug 2 is embedded into the screw hole 13, the plug 2 does not need to be screwed because the outer part of the plug has no threads, at the moment, the mounting disc 4 enters the inserting hole 11, and the pins 5 are inserted into the corresponding counter bores 14. After the movement of the plug 2 is blocked, the plug 2 is screwed to be screwed with the socket 1, the pins 5, the mounting disc 4 and the rotary drum 3 do not rotate along with the plug 2, and the plug 2 is driven to continue to move towards the socket 1 until the metal contact 52 is embedded into the metal contact 12, so that connection is completed.

Example two

Referring to fig. 5, the groove bottom of the sliding groove 42 at the end opposite to the transfer groove 41 (see fig. 4) is provided with a resilient stopper pin 44, and the resilient stopper pin 44 is coaxially arranged with the corresponding counter bore 14 (see fig. 2), and is arranged to be tapered toward the end of the socket 1. The pin 5 has a pin hole 53 on the end surface facing away from the socket 1 (see fig. 2), and when the pin 5 slides to the end of the sliding slot 42, the elastic limit pin 44 is inserted into the pin hole 53 to prevent the pin 5 from sliding freely.

The implementation principle of the above embodiment is as follows:

the bottom end of the elastic limit pin 44 is set to be conical, so that when the pin 5 slides forcefully, the elastic limit pin 44 can be pressed into the groove bottom of the sliding groove 42, and the sliding of the pin 5 is not affected at the moment. However, when the force of the sliding pin 5 is small, the sliding pin cannot move, and the position of the pin 5 is prevented from changing under the action of external force.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
