[0061] Example 1

[0062] like Figures 1 to 6As shown, this embodiment provides a cable limiting mechanism for a distribution cabinet, comprising a distribution cabinet composed of a cabinet body 2 and a cabinet door 8, and in order to facilitate heat dissipation, at least one group of heat dissipation holes 6 is opened on the cabinet body 2, and electronic components 5 for controlling, protecting and monitoring the operation of the power system are installed on the inner wall of the cabinet body 2 by means of fixed connections such as fastening screws.

[0063] Electronic components are usually connected to cables through terminals or terminal blocks. In actual applications, due to the lack of effective limiting mechanisms, they are prone to excessive stretching, resulting in damage to the insulation layer, which in turn causes short circuits or electrical failures, and even damage due to frequent friction, leading to fires. To solve the above technical problems, please refer to Figure 1-6 As shown, cable guides 4 and cable limiters 7 for limiting the main cable and auxiliary cable are respectively installed on both sides of the electronic components. The connecting rod 3 is installed inside the distribution cabinet through a fixing part 1 (connecting rod fixing seat), and at least one set of cable guides 4 is fixedly installed on the connecting rod 3.

[0064] A wiring sleeve 041 is installed on the seat of the cable guide 4 by means of a fixed connection such as welding, gluing or fastening screws, and the wiring sleeve 041 includes an outer sleeve and an inner sleeve arranged inside the outer sleeve, and a spring 042 is arranged in the cavity between the inner sleeve and the outer sleeve. During installation, one end of the spring 042 is fixedly installed on the inner wall of the outer sleeve, and the other end of the spring passes through the inner sleeve and is connected to the wiring plate 043 located inside the inner sleeve.

[0065] The cable tying plates 043 are arranged in two groups opposite to each other. The cable tying plates are arc-shaped plates. In order to avoid excessive force when the arc-shaped plates are clamped, which may cause damage to the cable sheath, an elastic pad is adhered to the end face of the arc-shaped plate away from the end of the spring.

[0066] In this embodiment, the staff first passes the cable of appropriate diameter through the cable tying sleeve 041. When the cable passes through the cable tying sleeve, a certain thrust is generated, and the spring is squeezed by the arc plate. After a certain length of cable passes through the cable tying sleeve 041, the force applied by the staff on the arc plate disappears, and the elastic force of the spring itself rebounds, causing the inner wall of the arc plate to conflict with the outer wall of the cable, and the cable is clamped by the arc plate.

[0067] Furthermore, the cable limiter 7 includes a guide rail 073, and the guide rail 073 is fixedly installed on the inner wall of the cabinet away from the side of the cable guide 4 by fastening screws, and a movable seat 072 is installed on the guide rail 073, and the movable seat 072 can be displaced along its longitudinal direction on the guide rail 073.

[0068] The side end faces of the movable seat 072 are each equipped with a limiting cylinder 074 for the cable to pass through, and a plurality of groups of partitions 077 are provided inside the movable seat 072, which divide the internal cavity of the movable seat 072 into a plurality of independent limiting grooves 078 for accommodating the limiting frame 079 through the plurality of groups of partitions 077, and the limiting frame 079 is provided with a rectangular groove for the pressure plate 075 to extend into.

[0069] Furthermore, a compression and telescopic spring 076 is installed on the connecting shaft of the pressure plate 075 , and the end surface of the compression and telescopic spring 076 at a position away from the pressure plate 075 is fixedly installed on the inner wall of the movable seat 072 .

[0070] During application, the staff first passes the auxiliary cable through the limit tube 074 and extends it into the limit frame 079 until the cable passes through the limit frame 079. The cable wiring path is limited by the setting of the limit frame. At the same time, when the cable passes through the limit frame, a certain force will be generated, which will in turn produce a certain compression on the compression telescopic spring. When the force applied by the staff disappears, the elastic force of the compression telescopic spring itself is used to cause the compression telescopic spring to rebound and drive the pressure plate to compress the cable for limiting the position.

[0071] Example 2:

[0072] The cable sleeve 041 is provided with a clamping end 103, and the clamping end is integrated with the cable sleeve 0041. A cable tube 102 is provided inside the clamping end 103, and the cable tube 102 passes through the cable sleeve 041 and extends to the outside.

[0073] Furthermore, the clamping end 103 is provided with at least three groups of evenly distributed limiting holes 104, each of which is provided with a limiting ball 101. When clamping a cable, the limiting ball 101 passes through the limiting holes 104 of the cable harness tube 102 and contacts the outer wall of the cable. Utilizing multiple groups of limiting balls, the cable is clamped at multiple points, thereby increasing the clamping force.

[0074] Furthermore, the limiting ball is made of elastic material

[0075] In order to prevent the limiting ball from being ejected from the limiting hole due to a large thrust during use, the cross-sectional area of ​​the limiting hole 104 gradually expands from the outside to the inside (from the wiring sleeve to the wiring tube) to form a tapered or expanded channel, so that the aperture of the limiting hole near the end of the wiring tube is larger than the aperture of the limiting hole away from the end of the wiring tube, and the limiting ball conflicts with the inner wall of the limiting hole near the end of the wiring tube.

[0076] In this embodiment, since the aperture of the limiting hole near the end of the wire harness tube is larger than the aperture of the limiting hole away from the end of the wire harness tube, and the limiting ball conflicts with the inner wall of the limiting hole near the end of the wire harness tube, it can effectively prevent the limiting ball from popping out of the limiting hole due to the increase in pushing force.

[0077] The use process and working principle of this utility model are:

[0078] When the utility model is used, the staff first passes the main cable of appropriate diameter through the cable sleeve 041. When the main cable passes through the cable sleeve, a certain thrust is generated, and the spring is squeezed by the arc plate. After a certain length of the main cable passes through the cable sleeve 041, the force applied by the staff on the arc plate disappears, and the elastic force of the spring itself rebounds, causing the inner wall of the arc plate to conflict with the outer wall of the main cable, thereby clamping the main cable through the arc plate.

[0079] Then the staff can install the main cable after passing through the cable barrel on the terminal block, and then use the pipe to bend it to facilitate the installation of the main cable on the electronic components;

[0080] Then install the auxiliary cable. The staff will pass the auxiliary cable through the limiting cylinder 074 and extend it into the limiting frame 079 until the cable passes through the limiting frame 079. The setting of the limiting frame limits the wiring path of the cable. At the same time, when the cable passes through the limiting frame, a certain force will be generated, which will in turn exert a certain pressure on the compression telescopic spring. When the force applied by the staff disappears, the elastic force of the compression telescopic spring itself is used to cause the compression telescopic spring to rebound and drive the pressure plate to compress the cable to limit the position.

[0081] The staff then installed the auxiliary cable on the terminal block and bent it using the pipe to facilitate connecting the auxiliary cable to the electronic components.

[0082] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
