[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] In order to extend the service life of the connector body 1, refer to Figure 1 , Figure 2 and Figure 3 As shown, it includes a connector body 1, a socket end 2, a lubrication unit, and a core shaft assembly. The socket end 2 is arranged on both sides of the connector body 1, and the core shaft assembly is centrally arranged in the socket end 2. The lubrication unit is arranged on the side of the socket end 2 facing the insertion direction, and reduces the friction when the plug is inserted into the socket end 2. The plug to be connected is aligned with the socket end 2 of the connector body 1. As the plug is slowly inserted, the outer wall of the plug will abut against the roller 5, and the roller 5 will roll along the outer wall of the plug to reduce the friction between the outer wall of the plug and the inner wall of the socket end 2, reduce the loss, and avoid shaking of the plug after insertion, thereby extending the overall service life.
[0020] To increase the connection distance, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lubrication unit includes a groove 3 opened inward from the outer surface of the socket end 2, and two engagement rods 4 and a roller 5 are arranged in the groove 3. When the plug enters the socket end 2, the roller 5 in the groove 3 will rub against the outer side of the plug entering the socket end 2 and rotate along the outer wall of the plug, which can avoid the outer wall of the plug directly contacting the inner wall of the socket end 2, so that long-term and multiple plug-in causes loss, so that the plug will show signs of shaking after being inserted into the socket end 2, affecting the transmission of current. Through the rolling of the roller 5, the friction is effectively reduced, the lubricity of the plug entering is improved, and the service life of the plug and the connector body 1 is extended. The upper and lower ends of the groove 3 are both open, and the two engagement rods 4 are respectively arranged on the left and right upper sides of the groove 3, and the roller 5 is arranged between the two engagement rods 4. The roller 5 extends into the socket end 2 through the opening and rubs against the outer side of the plug inserted into the socket end 2. The spindle assembly includes a spindle body 6 centrally arranged in the socket end 2, a cavity 7 is provided in the spindle body 6, a connecting cable 8 is arranged in the cavity 7, and a spring 9 is arranged on the outside of the connecting cable 8. When the plug distance is not enough, the spring 9 is stretched to pull the connecting cable 8, so that the connecting cable 8 changes through the deformation of the spring 9, so that the connecting core head 10 moves toward the plug direction to complete the transmission of current. The connecting cable 8 is provided with a connecting core head 10 on the side away from the cavity 7. With the deformation of the spring 9, the distance between the connecting core head 10 and the cavity 7 is increased, which can extend the connection and plugging distance of the connector body 1 and improve the overall practicality.
[0021] When in use, first align the plug to be connected to the socket end 2 of the connector body 1. As the plug is slowly inserted, the outer wall of the plug will abut against the roller 5, and the roller 5 will roll along the outer wall of the plug to reduce the friction between the outer wall of the plug and the inner wall of the socket end 2. When the distance of the plug inserted into the socket end 2 is not enough, pull the connecting core head 10, and through the deformation of the spring 9, the connecting cable 8 can be lengthened to complete the distance extension.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
