Specific implementation
[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] Please refer to Figure 1 -6, a copper bar plug-in connector, including plug-in male head seat 100, plug-in female head seat 200, positioning needle A 101, positioning needle B 102, wherein, on plug-in male head seat 100, two groups of plug-in male head columns 103 are equipped, and the plug-in hole 104 is equipped on each group of plug-in male head columns 103, and the inner metal ring 105 is fixedly connected on the inner wall of the plug-in hole 104, and the metal ear A 106 is fixedly connected on plug-in male head seat 100 corresponding to each group of plug-in male head columns 103, and the metal ear A 106 and the corresponding inner metal ring 105 are integrated structure, and the positioning needle A 101 and the positioning needle B 102 are fixedly connected on plug-in male head seat 100, and the positioning needle A 101 and the positioning needle B 102 here can be different in size or outline or fixed position;
[0025] Furthermore, the matching plug male head post 103 on the plug female head base 200 is provided with a plug recess 201, and a plug post head 202 is fixedly connected in the plug recess 201. An outer metal ring 203 is fixedly connected to the outer wall of the plug post head 202. A metal ear B 204 is fixedly connected to the plug female head base 200, and the metal ear B 204 is an integral structure with the outer metal ring 203. The matching positioning needle A 101 on the plug female head base 200 is provided with a positioning hole A 205, and the matching positioning needle B 102 is provided with a positioning hole B 206.
[0026] When the plug post head 202 is inserted into the plug hole 104, the outer metal ring 203 is in contact with the inner metal ring 105. Thus, when electrical connection is made through the connector, the metal ear A 106 on the plug male head base 100 can be connected with external wires, and the metal ear B 204 on the plug female head base 200 can be connected with another set of external wires. Then, the plug post head 202 on the plug female head base 200 is inserted into the plug hole 104 on the plug male head base 100, so that the inner metal ring 105 is in contact with the outer metal ring 203. Thus, electrical connection is achieved. Because the positioning needle A 101, the positioning needle B 102, the positioning hole A 205, and the positioning hole B 206 cannot be cross-inserted, when electrical connection is made, it is ensured that the two parts are always correctly connected during the insertion process, and connection errors are prevented.
[0027] Further to the embodiment, the plug female head base 200 is provided with a limiting part 300, and the plug male head base 100 is provided with a limiting piece 400 that cooperates with the limiting part 300. The cooperation between the limiting piece 400 and the limiting part 300 enhances the stability between the plug male head base 100 and the plug female head base 200. Further, in the embodiment, the limiting part 300 includes an outer shell 301, a lever arm 302, and a spring 303. That is, the outer shell 301 is fixedly connected to the plug female head base 200. The lever arm 302 is rotatably connected inside the outer shell 301. One end of the lever arm 302 is provided with a hook groove 304. The other end of the lever arm 302 is provided with a pressing table 305. The spring 303 is fixedly connected to the lever arm 302 near the hook groove 304, and the other end of the spring 303 is fixedly connected to the plug female head base 200. The outer shell 301 is provided with a pressing opening corresponding to the pressing table 305. The pressing table 305 protrudes out of the pressing opening. The outer shell 301 is provided with a penetrating opening 306 corresponding to the hook groove 304.
[0028] The limiting piece 400 includes a hook post 401 and a connecting frame 402. The connecting frame 402 is fixedly connected to the plug male head base 100, and the hook post 401 is fixedly connected to the end of the connecting frame 402. The hook post 401 cooperates with the hook groove 304.
[0029] Further, the end of the lever arm 302 near the hook groove 304 is provided with an arc surface 307.
[0030] Thus, when the plug male seat 100 is plugged with the plug female seat 200, the hook column 401 can enter the shell 301 through the penetrating port 306, at this time, because the end of the lever arm 302 is the arc surface 307, thus the hook column 401 can push the lever arm 302 to rotate, so that the spring 303 is stretched, when the hook column 401 continues to move, under the action of the spring 303, the lever arm 302 can be lowered, at this time, the hook groove 304 forms the limiting action to the hook column 401, so as to avoid the plug male seat 100 and the plug female seat 200 from being loosened due to vibration, causing the electrical connection failure;
[0031] When it is needed to separate the plug male seat 100 from the plug female seat 200, the lower pressing table 305 can be pressed down, at this time, the lever arm 302 is rotated, so that the end of the lever arm 302 provided with the hook groove 304 is upwardly buckled, at this time, the hook groove 304 releases the limiting of the hook column 401, so that the two can be separated.
[0032] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-restrictive, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
[0033] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can be properly combined to form other embodiments which can be understood by those skilled in the art.
