DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1 to 7 As shown, the connecting device of the cable conductor and the metal conductor of the present invention is connected to the cable conductor 1 and the metal conductor 4 respectively, and includes a plug 2 and a connector 3, wherein the connector 3 is a bilaterally symmetrical structure, which includes a support tube 7 and 8 conductive sheets 6, each conductive sheet 6 is respectively arranged on the surface of the support tube 7, and the 8 conductive sheets 6 cover the support tube 7 to form a connector, and one end of the plug 2 is connected to the cable conductor 1, and the other end is inserted into the inside of the connector 3 and electrically connected to the conductive sheet 6. The end of the connector 3 away from the plug 2 is electrically connected to the metal conductor 4 through the conductive sheet 6, thereby realizing the electrical connection between the cable conductor 1 and the metal conductor 4.

[0028] The support tube 7 of the present invention is a cylindrical body with several groups of positioning holes 7.1 uniformly arranged on its surface. Each conductive sheet 6 is provided with a positioning protrusion 6.1. Each conductive sheet 6 is secured to the surface of the support tube 7 by means of the positioning protrusion 6.1 engaging with the positioning hole 7.1. Furthermore, a boss 7.2 is provided at the end of the support tube 7 connected to the metal conductor 4. Each conductive sheet 6 is also provided with a positioning slot 6.2 that engages with the boss 7.2. The design of the positioning slot 6.2 further enhances the stability of the connection between the conductive sheet 6 and the support tube 7.

[0029] The eight conductive sheets 6 protrude from both ends of the support cylinder 7, and the protruding parts are respectively used as an electrical connection part one for electrical connection with the plug 2 and an electrical connection part two for electrical connection with the metal conductor 5. Both the electrical connection part one and the electrical connection part two are mounting holes, and the hole wall 8 of the mounting hole is an arc-shaped hole wall. In the present application, the hole wall 8 of the mounting hole is an arc-shaped hole wall, so the inner hole cross-sectional line of the mounting hole is not a straight line. When the mounting hole formed by the straight line is connected with the outer cylinder of the plug 2 or the metal conductor 5, the gap fit (no contact) or interference fit (difficult to assemble) phenomenon may occur. In the present application, the inner hole cross-sectional line of the mounting hole is an arc line, so when the mounting hole with the arc wall 8 is connected with the outer cylinder of the plug 2 or the metal conductor 5, there is certainly a part of the interference fit to ensure the contact, but the length of the interference fit is not long, which reduces the difficulty of assembly, and the design can improve the effectiveness of the electrical connection between the connector 3 and the plug 2 and the metal conductor 4.

[0030] In the electrical connection part one, each conductive sheet 6 is provided with a groove 6.3, and after the eight conductive sheets 6 cover the support cylinder 7, each groove 6.3 is combined to form a clamping groove in the electrical connection part one. The plug 2 is connected by a plug-in part 2.1 and a cylinder body 2.2, and the cylinder body 2.2 is provided with an inner hole 2.3 for the insertion of the cable conductor 1. The plug-in part 2.1 is connected by a conical part one 2.1.1, a cylindrical part one 2.1.2, a conical part two 2.1.3, and a cylindrical part two 2.1.4 in sequence, wherein the cylindrical part two 2.1.4 is connected with the cylinder body 2.2, and the maximum outer diameter of the conical part two 2.1.3 is greater than the outer diameter of the cylindrical part two 2.1.4, that is, the conical part two 2.1.3 forms a reverse hook structure. The plug 2 is inserted into the inside of the support cylinder 7 and positioned by the reverse hook structure and the clamping groove. This way not only can improve the stable positioning of the plug 2 inside the support cylinder 7, but also can improve the stability of the electrical connection between the plug 2 and the conductive sheet 6, and facilitate the plug-in and pull-out of the plug 2.

[0031] When the cable conductor 1 is installed, the diameter of the cable conductor 1 is slightly smaller than the inner diameter of the inner hole 2.3 of the plug 2, the cable conductor 1 is inserted into the inner hole 2.3 of the plug 2, and the cable conductor 1 and the plug 2 form an integrated structure by surrounding pressure, so that the cable conductor 1 is transformed into a conductor with a conical end. The inner diameter of the inner hole 2.3 can be adjusted according to the outer diameter of the cable conductor 1, that is, different cross-sections of the cable conductor 1 can be connected with the metal conductor 4 by adjusting the inner hole 2.3.

[0032] The present application also includes a clamping spring 5 for preventing the conductive sheet 6 from spreading, which is sleeved outside the connector 3, specifically, the clamping spring 5 is sleeved outside the electrical connection part one and the electrical connection part two of the conductive sheet 6.

[0033] In use, the cable conductor 1 can be electrically connected with the metal conductor 4 through the plug 2 and the connector 3 of the application, the connecting device of the application has strong versatility and can be applied to the connection of cable conductors 1 of different voltage grades, thereby improving the stability, reliability and safety of the cable connection operation. In addition, the plug 2 can be inserted into the connector 3 or pulled out of the connector 3, that is, the plug 2 can be conveniently plugged and unplugged and the cable conductor 1 can be installed, replaced or maintained, and the application has strong practicability.

[0034] The above embodiments are the preferred embodiments of the application, but the embodiments of the application are not limited to the above embodiments, and any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the application should be equivalent replacement methods and should be included in the protection scope of the application.
