A magnetic type cross grounding connecting device

Abstract

This utility model discloses a magnetic bridging grounding connection device, including a bridging wire. Both ends of the bridging wire are connected to fixing members. Each fixing member includes a grounding block and a magnetic element connected together. One end of the bridging wire is fixedly connected to the grounding block. This application utilizes the magnetic attraction properties of the magnetic element to attract and connect one end of the grounding block to the equipment requiring grounding, while the other end of the grounding block is separately connected to a grounding flat iron. This connects the bridging wire to the equipment requiring bridging grounding, achieving the function of temporary bridging grounding.

Description

Technical Field

[0001] This utility model belongs to the field of electromechanical installation technology, specifically relating to a magnetic bridging grounding connection device. Background Technology

[0002] In the construction industry, temporary grounding is a crucial element in ensuring the safe operation of temporary power systems. Its main purpose is to prevent accidental energization, reduce the risk of electric shock, and ensure the safety of equipment during maintenance and repair. Traditionally, this involves bolting or welding, such as installing dedicated grounding terminals (e.g., grounding flat iron) in critical locations like distribution rooms and switch rooms, then connecting jumper wires to the grounding flat iron with galvanized bolts to achieve grounding. After completion, these terminals need to be removed. However, temporary construction involves numerous and dispersed temporary grounding points, leading to cumbersome installation and removal work. Furthermore, the numerous spare parts (such as bolts and nuts) require manual collection and installation, wasting manpower and resources. Utility Model Content

[0003] To solve the above problems, this utility model provides a magnetic bridging grounding connection device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A magnetic bridging grounding connection device includes a bridging wire, with fixing members connected to both ends of the bridging wire. The fixing members include a grounding block and a magnetic element connected together, and the end of the bridging wire is fixedly connected to the grounding block.

[0006] In a further embodiment, the grounding block is embedded in the middle of the magnetic element, and at least one end is located outside the magnetic element.

[0007] In a further embodiment, the end of the jumper wire is welded to the grounding block.

[0008] In a further embodiment, a fastener is threaded onto the grounding block, and the end of the jumper wire is fixedly connected to the grounding block via the fastener.

[0009] In a further embodiment, the jumper wire is spiral-shaped.

[0010] In a further embodiment, the magnetic element is fitted with a heat-shrink sleeve around its outer periphery.

[0011] In a further embodiment, the magnetic element is a neodymium iron boron magnet, and the grounding block is made of iron.

[0012] Neodymium iron boron (NdFeB) magnets are among the permanent magnet materials with the highest known magnetic energy product, exhibiting high coercivity and strong magnetic attraction. These properties allow them to firmly adhere to the surface of metal pipes, enabling rapid installation and removal, making them particularly suitable for the quick connection and fixation of fluid pipelines and jumper cables.

[0013] Therefore, this application utilizes the magnetic attraction characteristics of magnetic elements to connect one end of the grounding block to the equipment that needs to be grounded (such as metal pipes, temporary electrical boxes, etc.), while the other end of the grounding block is connected to the grounding flat iron, thereby connecting the jumper wire to the equipment that needs to be grounded and achieving the function of temporary grounding.

[0014] When grounding of temporary prefabricated houses or temporary electrical boxes is required, one end of this magnetic bridging grounding connection device is attached to the box body of the temporary prefabricated house or temporary electrical box, and the other end is attached to the reserved grounding flat iron, thus achieving bridging grounding. It is easy to connect and remove; simply pull the fixing piece away. It has the advantages of fast assembly and disassembly, high stability, support for multi-angle attachment, and recyclability, improving work efficiency and reducing costs.

[0015] Therefore, the magnetic bridging grounding connection device of this application can achieve quick installation / removal. It is especially suitable for scenarios requiring frequent maintenance or temporary setup (such as construction sites, emergency repairs), and has significant market value.

The illustrative embodiments of this application and their descriptions are used to explain this application and do not constitute an undue limitation of this application.

[0020] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0021] like Figure 1-2 As shown, a magnetic bridging grounding connection device includes a bridging wire 1, with fixing members connected to both ends of the bridging wire 1. The fixing members include a grounding block 3 and a magnetic element 2 connected together, and the end of the bridging wire 1 is fixedly connected to the grounding block 3.

[0022] In this embodiment, the magnetic element 2 is a neodymium iron boron magnet, the grounding block 3 is made of iron, and the jumper wire 1 is an electric wire.

[0023] In this embodiment, the grounding block 3 is embedded in the middle of the magnetic element 2, and at least one end is located outside the magnetic element 2, which facilitates connection with the jumper wire 1.

[0024] In one embodiment, the end of the jumper wire 1 is welded to the grounding block 3, such as... Figure 1 As shown.

[0025] In another embodiment, a fastener 4, preferably a bolt, is threaded onto the grounding block 3. The end of the jumper wire 1 is wound around the bolt, and the jumper wire 1 is fixedly connected to the grounding block 3 by tightening the fastener 4. Figure 2 As shown.

[0026] For ease of operation, the jumper wire 1 is spiral-shaped, and its length can be extended or stretched according to the actual distance, thereby improving its adaptability. When the distance is short, the spiral shape of the jumper wire 1 ensures neatness and avoids tangling caused by excessive length.

[0027] In a further embodiment, the magnetic element 2 is fitted with a heat-shrink sleeve, preferably made of epoxy resin, which has anti-corrosion and anti-interference functions.

[0028] When grounding of temporary prefabricated houses or temporary electrical boxes is required, one end of this magnetic grounding connection device is attached to the box body of the temporary prefabricated house or temporary electrical box, and the other end is attached to the reserved grounding flat iron, thus achieving grounding. This prevents accidental energization, reduces the risk of electric shock, and ensures the safety of equipment during inspection or maintenance. This device is easy to install and remove; removal simply requires pulling the fixing part away. It features fast installation and removal speed, high stability, support for multi-angle attachment, and recyclability, improving work efficiency while reducing costs.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application shall be within the scope of protection of the pending claims of this application.
