Description
Technical Field
[0001] The utility model relates to a static electricity elimination device, in particular to a magnetic attraction type anti-fall type static electricity grounding wire connector. Background Art
[0002] Static electricity is formed by friction or the redistribution of charges caused by mutual attraction of charges. There are many hazards of static electricity. When the aircraft body or the moving vehicle rubs against particles such as air, water vapor, and dust, the aircraft will be charged, which will seriously interfere with the normal operation of the aircraft's radio equipment and the safety of special transport vehicles carrying goods. For example, in a printing factory, static electricity between paper pages will make the paper pages stick together and difficult to separate. In a pharmaceutical factory, static electricity attracts dust, which will make the medicine fail to reach the standard purity. In industrial production, static electricity can cause electronic equipment to malfunction or malfunction, causing electromagnetic interference. When playing TV, static electricity on the surface of the screen easily absorbs dust and oil, forming a layer of dust film. In coal mines, static electricity can cause gas explosions, resulting in the death and injury of workers and the scrapping of mines. These are the many negative effects of static electricity on industrial production and life. Therefore, eliminating static electricity is a must in many places.
[0003] The static grounding wire connector, also known as the static elimination wire contact head, is an important component of the static elimination wire dedicated to modern oil and gas transportation vehicles and special transportation vehicles. The device is mainly suitable for special transportation vehicles, electronic assembly workshops, chemical and pharmaceutical loading workshops, workpiece assembly line platforms, industrial production, high-voltage equipment maintenance sites, and new energy vehicle maintenance fields. It is an important and indispensable component of the static elimination wire. It can effectively eliminate static electricity in vehicles, maintenance platforms, loading water flow lines, and test products in construction environments, creating zero static electricity and thus playing a role in safety protection.
[0004] The connector of the traditional first-generation static grounding wire is a U-shaped hook made of aluminum. The U-shaped hook has a double-tongue structure on both sides. It is large and occupies a large space. After connecting the grounding wire, it can be effectively plugged into the grounding point of the transport vehicle. However, the hook body wire clamp design is relatively bulky, and due to the deadweight of the wire body after wiring, the structure often rotates backwards and breaks when the vehicle moves forward, and the hook body is taken away with the vehicle or falls off and breaks, which is not ideal.
[0005] The connector of the second-generation static grounding wire is a clamp-type wire clamp made of cast aluminum, which is also made of the principle of spring-loaded lever structure. Although the clamp body is much smaller than the first-generation U-shaped hook wire clamp, the effective opening of the clamp-type wire clamp is small, and the vehicle grounding points that can be supported are greatly limited. In addition, manual operation is still required for removal. Forgetting to remove it will cause the jaws to break, which will greatly affect the efficiency of static elimination work.
[0006] Later, the third generation was improved to a clamp-type contact head made of stamped 65# steel plate. Although the hardness was greatly improved, the steel material itself has low conductivity and is easy to rust when used outdoors, often resulting in poor contact. In addition, the conical thorns on the teeth damaged the paint surface and coating of the vehicle at the contact position. Each connection and use would damage the paint surface of the clamped part to a certain extent. In addition, the conical teeth also reduce the contact area in terms of contact, so a longer release time is required in the static elimination process. Therefore, we urgently need a static elimination grounding wire connector that can avoid the above problems. Utility Model Content
[0007] The purpose of the invention of the utility model is to provide a magnetic anti-drop electrostatic grounding wire connector, which has a magnetic design and an anti-drop structure. It can be arbitrarily magnetically attached to the exposed steel structure or frame of equipment such as tank trucks that need to eliminate static electricity. The contact point range is wide, and the contact area is larger than the three generations introduced above, and the static electricity elimination effect is better. It is more casual to hold and extremely simple to operate during use, and can be operated with eyes closed. The disassembly operation does not require manual operation. When special vehicles and other equipment leave, it can be detached automatically without manual operation, avoiding the damage and loss caused by forgetting to remove the electrostatic grounding wire clamp in the past. It will not damage the paint and coating of the clamped part of the vehicle, has anti-drop protection, and is more durable.
[0008] The technical solution of the utility model is:
[0009] The utility model discloses a magnetic suction type anti-drop type electrostatic grounding wire connector, which comprises a magnetic suction head main body, which is set as a solid structure and is made of conductive material throughout; the front part of the magnetic suction head main body is set as a cylindrical magnetic suction head, and the rear part is provided with a plate-shaped connector connected to the electrostatic grounding wire; a groove is provided on the front end contact surface of the front part of the magnetic suction head main body, and a conductive permanent magnet is embedded and fixed in the groove; and anti-drop spring structures are evenly distributed on the sides around the front part of the magnetic suction head main body.
[0010] Furthermore, the front portion of the magnetic suction head body of the utility model can also be set to a regular shape such as a regular polygonal prism.
[0011] Furthermore, a cylindrical holding portion for holding can be provided at the rear of the magnetic suction head body of the utility model between the connector connected to the electrostatic grounding wire and the front magnetic suction head.
[0012] Furthermore, the diameter of the holding portion of the utility model is set to be smaller than the diameter of the front magnetic suction head.
[0013] Furthermore, in the present invention, an insulating sleeve may be sleeved on the above-mentioned gripping portion.
[0014] Furthermore, the anti-fall spring of the utility model can be detachably installed on the sides around the front part of the magnetic suction head body.
[0015] Furthermore, the magnetic suction head body of the utility model is made of aluminum; and the conductive permanent magnet is made of neodymium iron boron magnet.
[0016] The beneficial effects of the utility model are as follows: the design of the utility model is more compact and flexible than the traditional wire clamp contact head, and it is more convenient and simple to use, operate, carry, and disassemble after use. It does not even need to be manually disassembled after use, and it saves space when placed. The magnetic suction head body does not need to be held after connecting the ground wire, and the strong magnetic contact head automatically adsorbs and connects as long as it is close to the clamped part. It also has an anti-fall structure. In short, the use of the utility model solves the problems that the traditional clamp type is not resistant to falling and easy to damage, and needs to be manually disassembled after use. Once forgotten to disassemble, the clamp and even the ground wire will be damaged, as well as the low conductivity, low efficiency, easy to rust, and will damage the paint surface of the contact position. In addition, the traditional clamp type cannot be applied to all equipment and places that need to eliminate static electricity, which limits the place of use, while the utility model can be applied to all places and equipment that need to eliminate static electricity. The installation and removal of the utility model product is extremely convenient and worry-free, and the weight is greatly reduced, which is more conducive to carrying, installing and disassembling operations. Its connection contact is more reliable, the contact surface is larger, the conductivity is improved, the static electricity elimination effect is better, and the release efficiency is faster.
[0017] The utility model magnetic anti-drop type static grounding wire connector can also be called static elimination wire contact head. It is mainly suitable for modern oil and gas transportation vehicles and special transportation vehicles, electronic assembly workshops, chemical and pharmaceutical loading workshops, assembly line platforms, industrial production, high-voltage equipment maintenance sites and new energy vehicle maintenance fields. It is an indispensable component of the static grounding wire, which can effectively eliminate the static electricity of the above-mentioned environmental equipment, thereby playing a role in safety protection.

[0022] As attached Figure 1 , 2, 3, and 4 show an embodiment of a magnetic drop-proof electrostatic grounding wire connector of the utility model, which includes a magnetic head body 1, which is a solid structure and made of conductive material. The front part 1-1 of the magnetic head body 1 is set as a cylindrical structure and can be called a magnetic head, and the rear part is provided with a plate-shaped connector 1-2 connected to the electrostatic grounding wire 8; the connector 1-2 is provided with a screw hole 5, which is connected and fixed with the terminal 7 of the electrostatic grounding wire 8 by a fixing bolt 6. A groove 1-4 is provided on the front contact surface of the front part 1-1 of the magnetic head body 1, and a conductive permanent magnet 1-3 is embedded and fixed in the groove 1-4. The conductive permanent magnet 1-3 can be fixed in the groove 1-4 by a screw 4. In this way, the electrostatic grounding wire of the magnetic suction head can be thrown out at will when in use, and it can be effectively and quickly adsorbed on the exposed columns and various uneven positions of the steel structure of equipment such as tank trucks, without the need to deliberately set up a dedicated contact part as in the previous existing technology; when the vehicle completes the task and leaves, the magnetic suction head easily and automatically disengages from the contact point without human operation. Moreover, its conductive contact area is larger than that of the traditional clamp type, and its conductivity is better. Anti-drop springs 2 are evenly arranged on the sides around the front part 1-1 of the magnetic suction head body. The anti-drop springs 2 are detachably installed by screws 2 and 3 and are evenly arranged on the sides around the front part 1-1 of the magnetic suction head body 1. The anti-drop spring structure effectively reduces the ability of this product to resist falling when it falls off automatically, effectively protects the product from being broken, and is more durable.
[0023] In actual use, the front portion of the magnetic suction head body of the utility model can also be set to a regular polygonal prism or other shape.
[0024] In actual use, the utility model can also be provided with a cylindrical gripping portion for holding at the rear of the magnetic head body between the connector connected to the electrostatic grounding wire and the front magnetic head.
