Description

Technical Field

[0001] This invention relates to the field of cable plug-in components, specifically a cable plug-in component. Background Technology

[0002] Cable plug-in components are specialized connection devices used in power systems to connect cables to electrical equipment such as switchgear, transformers, and cable junction boxes. They connect or disconnect circuits by inserting or removing the plug. Currently, existing cable plug-in components are all rigid plug-in types, primarily designed to increase connection strength. However, their conductive connectors are integrated structures, making it difficult to easily separate them from the connectors in the connected electrical equipment. Relying entirely on brute force for disconnection prevents the conductive connectors from being safely disconnected beforehand, leading to hazards such as external arcing and a low operational safety factor. Therefore, this paper proposes a new type of cable plug-in component to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a cable plug-in component in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a cable plug-in component, comprising an insulating shell integrated with a plastic insulating component and a conductive core, wherein the conductive core portion located inside the insulating shell is configured as a twisted section, and the twisted section forms a push-pull motion on both ends of the conductive core by twisting, and an insulating rod is fixedly connected to an insulating block located on the twisted section, and the middle part of the insulating rod is assembled with a ceramic bearing located on the plastic insulation.

[0005] In a further technical solution, ceramic tubes are connected to both the left and right ends of the insulating shell, and a linear portion of a conductive core is introduced into the interior of each ceramic tube.

[0006] In a further technical solution, the ceramic tube and the corresponding part of the plastic insulating component are integrally bonded together.

[0007] In a further technical solution, the tortuous segment is a resiliently repositionable part.

[0008] In a further technical solution, the right end and the bottom end of the plastic insulating component are respectively provided with a first plug-in end and a second plug-in end, and the first plug-in end and the second plug-in end are respectively connected to two ceramic tubes on the same side.

[0009] A further technical solution is that the first plug-in element located at the first plug-in end is electrically connected to one end of the conductive core, and the second plug-in element located at the second plug-in end is electrically connected to the other end of the conductive core, with a corrugated plastic short tube fitted at the electrical connection.

[0010] In a further technical solution, an insulating handle is installed at the outer end of the insulating rod.

[0011] The beneficial effects of this invention are: by turning the insulating handle in the forward or reverse direction, the twisted section connected by the insulating rod and insulating block is driven to twist, forming a pull on both ends of the conductive core. After being released, the twisted section can be elastically reset, so that both ends of the conductive core can be automatically reset, achieving the effect of pushing and pulling the plug-in elements at both ends of the conductive core. This can not only apply a compensating force to the plug-in point to ensure the firmness of the plug-in point, but also conveniently cut off the conductivity when the cable plug-in parts are not pulled out, thus improving the safety of the plug-in operation.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Therefore, they should not be construed as limitations on this invention.

[0019] Please see Figure 1-3 As shown, a cable plug-in component includes an insulating shell 5 integrated with a plastic insulating component 1 and a conductive core 2. The conductive core 2 located inside the insulating shell 5 is configured as a twisted section 210, and the twisted section 210 forms a push-pull motion on both ends of the conductive core 2 by twisting. An insulating rod 8 is fixedly connected to an insulating block 6 located on the twisted section 210, and the middle part of the insulating rod 8 is assembled with a ceramic bearing 7 located on the plastic insulation. Twisted segment 210: The twisted segment 210 is an elastically repositionable part, and its specific implementation effect is as follows: Twisting the insulating handle 9 in either the forward or reverse direction causes the twisted section 210, connected by the insulating rod 8 and the insulating block 6, to twist, forming a pull on both ends of the conductive core 2. After being released, the twisted section 210 elastically resets, allowing both ends of the conductive core 2 to automatically reset. This achieves the effect of pushing and pulling the plug-in components at both ends of the conductive core 2, which can both apply a compensating force to the plug-in point to ensure the firmness of the plug-in point and conveniently cut off the conductivity when the cable plug-in components are not pulled out, thus improving the safety of the plug-in operation.

[0020] Combination Figure 1 and Figure 3 As shown, ceramic tubes 510 are connected to both the left and right ends of the insulating shell 5, and a straight section of a conductive core 2 is introduced into each ceramic tube 510. The ceramic tubes 510 are integrally bonded to the corresponding parts of the plastic insulating component 1. Ceramic tube 510: used to guide the linear movement of the conductive core 2, and is wear-resistant and insulating. It is also integrally bonded with the plastic insulating part 1 to achieve an overall external insulation effect.

[0021] The plastic insulating component 1 is provided with a first plug-in end 110 and a second plug-in end 120 at its right end and bottom end, respectively. The first plug-in end 110 and the second plug-in end 120 are respectively connected to two ceramic tubes 510 on the same side.

[0022] like Figure 1As shown, the first plug-in element 3 located at the first plug-in end 110 is electrically connected to one end of the conductive core 2, and the second plug-in element 4 located at the second plug-in end 120 is electrically connected to the other end of the conductive core 2. A corrugated plastic short tube 130 is fitted at the electrical connection. The corrugated plastic short tube 130 is elastic and can move with the end of the conductive core 2 while providing a sealing effect.

[0023] An insulating handle 9 is installed at the outer end of the insulating rod 8.

[0024] Compared with existing technologies, the difference lies in the fact that: turning the insulating handle 9 in the forward or reverse direction causes the twisted section 210 connected by the insulating rod 8 and the insulating block 6 to twist, forming a pull on both ends of the conductive core 2. After being released, the twisted section 210 can be elastically reset, so that both ends of the conductive core 2 can automatically reset, achieving the effect of pushing and pulling the plug-in elements at both ends of the conductive core 2. This can not only apply a compensating force to the plug-in point to ensure the firmness of the plug-in point, but also conveniently cut off the conductivity when the cable plug-in elements are not pulled out, thus improving the safety of the plug-in operation.
