The two end faces of the rotor 2, which are far away from each other, are integrally formed with rotating shafts 21 (see fig. 2), the rotor 2 is arranged in the U-shaped notch, the rotating shafts 21 are inserted between the two shells 1 to rotate, the side wall of the rotor 2, which is close to the bottom surface of the U-shaped notch, is arc-shaped, and the axis of the arc-shaped face coincides with the axis of the rotating shafts 21. The terminal 3 sets up respectively in two lateral walls that rotor 2 was provided with pivot 21, and pivot 21 passes terminal 3 and its and terminal 3 contactless, and conducting strip 4 sets up in two lateral walls that U type notch was kept away from each other, and its one end that passes casing 1 and keep away from rotor 2 is connected with electrically conductive, and conducting strip 4 just switches on with nearest terminal 3 butt respectively, and conducting strip 4 and terminal 3 are copper, and pivot 21 passes conducting strip 4 and both contactless. Two casings 1 are close to each other and the equal integrated into one piece in same position has fastening rod 12, and two casings 1 are close to each other and the same position has all seted up fastening groove 11, and fastening rod 12 inserts and arranges in fastening groove 11 of adjacent casing 1. When inserting terminal 3 of plug in the socket, thereby can rotate rotor 2 and make casing 1 perpendicular with terminal 3, the wire that conducting strip 4 was connected this moment is difficult for receiving the oppression and produces the damage, reduces the required space of process that the plug inserted on the socket simultaneously, makes the use of plug more convenient.

As shown in fig. 2, mounting groove 22 has all been seted up to two lateral walls of its axis of rotation of rotor 2 perpendicular to, and mounting groove 22 runs through the terminal surface that its arc surface was kept away from to rotor 2, and pivot 21 is located mounting groove 22 towards the lateral wall of U type notch inner wall, and terminal 3 is arranged in mounting groove 22 and its two lateral walls laminating of keeping away from each other with mounting groove 22, and terminal 3 is close to the lateral wall that U type notch and rotor 2 are provided with pivot 21's lateral wall and is in the coplanar. The side wall of the mounting groove 22 connected with the rotating shaft 21 is integrally formed with a positioning rod 23, and the positioning rod 23 is positioned on one side of the rotating shaft 21 far away from the arc surface. The terminal 3 is perpendicular to the end face of the rotor 2 rotation axis and is provided with a positioning hole 31, the positioning rod 23 is inserted in the positioning hole 31, and the outer wall of the positioning rod 23 is attached to the inner wall of the positioning hole 31. The position of the terminal 3 is limited by the mounting groove 22, and the terminal 3 does not move towards the bottom of the U-shaped notch by the positioning rod 23, so that the terminal 3 is not easy to slide relative to the rotor 2 in the process of being inserted into the socket, and the plug is more stable to use.

As shown in fig. 2, when the positioning rod 23 applies a force to the terminal 3 to prevent the terminal from moving toward the bottom of the U-shaped notch, the contact area between the positioning rod 23 and the terminal 3 is small, and the pressure between the positioning rod 23 and the terminal 3 is large, which may easily cause damage to the positioning rod 23. Therefore, the side of the positioning rod 23 away from the arc surface is provided with an abutting surface 231, the abutting surface 231 is perpendicular to the side wall of the rotor 2 away from the arc surface, and the abutting surface 231 is attached to the inner wall of the positioning hole 31.

As shown in fig. 3, since the terminal 3 may rotate along the axis of the rotating shaft 21, and after a plurality of rotations, the rotating shaft 21 may be worn to cause the conductive sheet 4 to be unable to contact with the terminal 3, thereby causing the power failure, a plurality of inclined elastic conductive portions 41 are integrally formed on the side wall of the conductive sheet 4 close to the terminal 3, the elastic conductive portions 41 are disposed around the axis of the rotating shaft 21, the extension lines of the elastic conductive portions 41 in the length direction do not intersect with the axis of the rotating shaft 21, and one end of the elastic conductive portion 41 away from the conductive sheet 4 contacts with the terminal 3. After the distance between the conductive sheet 4 and the terminal 3 is increased, one end of the elastic conductive part 41, which is far away from the conductive sheet 4, deforms towards the terminal 3, and the terminal 3 is conducted with the conductive sheet 4 by the elastic conductive part 41, so that the using process of the plug is more stable.

As shown in fig. 3, since the rotor 2 rotates back and forth, when the terminal 3 rotates toward the end surface of the elastic conductive portion 41 away from the conductive sheet 4, the edge at the end of the elastic conductive portion 41 directly contacts the terminal 3, and the pressure at the contact position between the terminal 3 and the conductive sheet is high, which causes abrasion on the surface of the terminal 3 and affects the service life of the terminal 3. Therefore, one end of the elastic conductive part 41, which is far away from the conductive sheet 4, is bent towards the conductive sheet 4, and the edge of the end part of the elastic conductive part 41 is not directly contacted with the terminal 3, so that the contact area between the elastic conductive part 41 and the terminal 3 is increased, the pressure between the elastic conductive part 41 and the terminal 3 is reduced, and the terminal 3 is not easily abraded.

As shown in fig. 2, since the conductive sheets 4 are directly disposed on two sidewalls of the U-shaped slot, the conductive sheets 4 are exposed to the outside, and thus may still be damaged. Therefore, the clamping grooves 13 are formed in the two side walls, away from each other, of the U-shaped groove opening of the shell 1, the clamping grooves 13 penetrate through the end faces, close to each other, of the two shell 1, and the clamping grooves 13 penetrate through the side walls, away from the U-shaped groove opening, of the shell 1. The conducting strip 4 is arranged in the clamping grooves 13 which are communicated with each other of the two shells 1, and the side wall of the conducting strip 4 close to the terminal 3 and the inner wall of the U-shaped groove are on the same plane. Utilize joint groove 13 to hold conducting strip 4, make conducting strip 4 be difficult for exposing in U type notch, the difficult condition that appears human and conducting strip 4 contact this moment to the emergence of the dangerous condition has been reduced.

As shown in fig. 2, in order to make conducting strip 4 be difficult for producing the slip when the atress, spacing groove 14 has all been seted up to joint groove 13 bottom surface, two terminal surfaces that conducting strip 4 kept away from each other equal integrated into one piece have stopper 42, stopper 42 joint is in spacing groove 14, utilize stopper 42 and spacing groove 14's cooperation to restrict conducting strip 4's removal, make conducting strip 4 be difficult for producing relative movement with casing 1 to make conducting strip 4 and terminal 3's connection more stable.

The working principle is as follows:

when the plug is used, the rotor 2 is rotated to adjust the angle between the terminal 3 and the housing 1, and at this time, when the terminal 3 is inserted into the socket, the space occupied by the whole plug is reduced, and when the rotor 2 rotates and the distance between the terminal 3 and the conductive sheet 4 changes, the elastic conductive portion 41 is moved toward the terminal 3 by its own elastic force, and the conductive sheet 4 is kept in conduction with the terminal 3 by the elastic conductive portion 41.

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.
