Torque energy-saving clamp

Abstract

This utility model discloses a torque-saving wire clamp, relating to the field of wire clamp technology. The utility model includes a wire clamp body for connecting wires or cables to cables, and a wiring mechanism installed inside the wire clamp body for connecting cables to the wire clamp body. This utility model incorporates a dustproof component. Specifically, when a cable is inserted into the wiring slot, the arc-shaped clamp blocks are pushed away from each other and stretch the annular spring. The spring's rebound force returns the arc-shaped clamp blocks to their original position and fits against the cable. During this process, rack one slides, driving gears to rotate, which in turn drives rack two to move closer together.

Simultaneously, reducing dust contact slows down equipment wear and corrosion, extending its service life.

Description

Technical Field

[0001] This utility model belongs to the field of wire clamp technology, and in particular relates to torque-saving wire clamps. Background Technology

[0002] In power systems, torque-saving clamps are devices used to connect conductors or cables. Their design aims to ensure the stability and reliability of electrical connections while reducing energy loss. The wiring channel is an important component of the torque-saving clamp, responsible for accommodating and protecting the connection points of the conductors. However, since the wiring channel is usually located outdoors or in harsh environments, it is susceptible to dust, moisture, and other contaminants. This can lead to the dust inside the wiring channel becoming damp and forming conductive paths, increasing the risk of leakage and reducing the safety and stability of power transmission. At the same time, it also increases the contact between dust and equipment, accelerating wear and corrosion and shortening the service life of the equipment. Therefore, a torque-saving clamp is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a torque-saving cable clamp. By setting a dustproof component, specifically when the cable is inserted into the wiring slot, the arc-shaped clamp blocks are pushed away from each other and stretch the ring spring. The rebound force of the ring spring causes the arc-shaped clamp blocks to return to their original position and fit against the cable, achieving auxiliary clamping and fixation. During this process, rack one slides and drives the gear to rotate, driving rack two to move closer together. Rack two pushes the push rod to expand the insulating rubber sleeve and fit against the surface of the cable. At this time, the insulating rubber sleeve can fill the gap and prevent dust from entering the wiring slot. This solves the problem that wiring slots are usually located outdoors or in harsh environments, so they are easily affected by dust, moisture and other pollutants, which can lead to the dust inside the wiring slot becoming damp and forming a conductive path, increasing the risk of leakage and reducing the safety and stability of power transmission. At the same time, it can also increase the contact between dust and equipment, accelerate the wear and corrosion rate, and shorten the service life of the equipment.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a torque-saving wire clamp, including a clamp body for connecting wires or cables to cables, and further including:

[0006] A wiring mechanism is installed inside the clamp body and is used to connect the cable to the clamp body.

[0007] The clamp body has two wiring grooves inside, an opening on the right side, an anti-slip threaded sleeve on the right side inside, and two fastening bolts connected to the right side inside.

[0008] Furthermore, the wiring mechanism includes a clamping assembly that abuts against the wiring slot and is used to assist in clamping the cable;

[0009] A dustproof assembly, connected to a clamping assembly, is used to prevent dust from entering the wiring slot; and

[0010] An anti-loosening component is provided, which abuts against the wire clamp body and is used to prevent the wire clamp body from falling off during use.

[0011] Furthermore, there are two sets of clamping components, each set located inside the wiring slot. The two sets of clamping components contain the same parts. The clamping component located on the front includes a rack, and the number of racks is several.

[0012] Furthermore, the inner wall of the wiring groove is provided with several limiting grooves, the outer surface of several racks is slidably connected to the inner wall of the limiting groove, several racks penetrate the limiting groove and extend into the inside of the clamp body, and an arc-shaped clamping block is welded to one side of each rack, and an annular spring is sleeved on the outer ring of each arc-shaped clamping block.

[0013] Among them, several of the limiting grooves are connected to gears by pins, and the right side of several racks is meshed with the outer surface of the gears.

[0014] Furthermore, the dustproof component includes an insulating rubber sleeve, which is disposed on the right side of several arc-shaped clamps. The outer ring of the insulating rubber sleeve is connected to the inner wall of the wiring groove. Several push rods are in contact with the inner wall of the insulating rubber sleeve, and a rack is welded to the side of each push rod away from the inner wall of the insulating rubber sleeve.

[0015] Furthermore, several of the racks 2 penetrate the wiring groove and extend into the limiting groove, the outer surfaces of several racks 2 are slidably connected to the inner wall of the limiting groove, and the left sides of several racks 2 are meshed with the outer surface of the gear.

[0016] The dustproof components are in two sets, and the two sets of dustproof components are respectively installed inside the wiring slot. The two sets of dustproof components contain the same components.

[0017] Furthermore, the anti-loosening component includes four cavities, which are arranged in pairs. The two sets of cavities are respectively opened on the front and back sides of the right side inside the wire clamp body. Limiting plates are slidably connected to the corresponding sides inside the two sets of cavities, and several springs are connected to the sides of the two cavities that are far apart from each other.

[0018] Among them, the side of several springs away from the limiting plate is respectively connected to the inner wall of the cavity.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model incorporates a dustproof component. Specifically, when the cable is inserted into the wiring slot, the arc-shaped clamps are pushed away from each other and stretch the annular spring. The spring's rebound force resets the arc-shaped clamps and brings them into contact with the cable, thus achieving auxiliary clamping and fixing. During this process, rack one slides, driving the gear to rotate and causing rack two to move closer together. Rack two pushes the push rod, causing the insulating rubber sleeve to expand and fit against the cable surface. At this time, the insulating rubber sleeve can fill the gaps and prevent dust from entering the wiring slot, avoiding moisture and conductivity, reducing the risk of leakage, and ensuring the safety of power transmission. At the same time, reducing dust contact can slow down equipment wear and corrosion, and extend its service life.

[0021] 2. This utility model incorporates an anti-loosening component. Specifically, rotating the fastening bolt causes the opening of the clamp body to contract, and the anti-slip threaded sleeve clamps and fixes the cylinder. During this process, the spring inside the cavity is compressed and stores energy, while the spring also generates a rebound force to push the opening to expand. At this time, the clamp body generates a counter-pushing force on the fastening bolt, making it tightly adhere to the surface of the clamp body and maintain a taut state. This design effectively prevents the fastening bolt from loosening, reduces the risk of the clamp body falling off, and improves the stable use effect of the clamp body.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 As shown, this utility model is a torque-saving wire clamp, including a clamp body 111, which is used to connect wires or cables to cables, and also includes:

[0033] Wiring mechanism 2 is installed inside the clamp body 111 and is used to connect the cable to the clamp body 111.

[0034] The clamp body 111 has two wiring slots 112 inside, an opening on the right side of the clamp body 111, an anti-slip threaded sleeve 113 inside the right side of the clamp body 111, and two fastening bolts 114 connected to the right side of the clamp body 111.

[0035] The wiring mechanism 2 includes a clamping component 21, which abuts against the wiring groove 112 and is used to assist in clamping the cable.

[0036] Dustproof component 22 is connected to clamping component 21 and is used to prevent dust from entering the wiring slot 112; and

[0037] Anti-loosening component 23 abuts against the wire clamp body 111 and is used to prevent the wire clamp body 111 from falling off during use.

[0038] There are two sets of clamping components 21, which are located inside the wiring slot 112. The two sets of clamping components 21 contain the same components. The clamping component 21 located on the front includes a rack 211, and there are several racks 211.

[0039] The inner wall of the wiring groove 112 is provided with several limiting grooves 212. The outer surfaces of several racks 211 are slidably connected to the inner wall of the limiting grooves 212. Several racks 211 pass through the limiting grooves 212 and extend into the wire clamp body 111. An arc-shaped clamping block 213 is welded to the corresponding side of several racks 211. A ring spring 214 is sleeved on the outer ring of several arc-shaped clamping blocks 213.

[0040] Among them, several limiting grooves 212 are connected to gears 215 through pins, and several racks 211 are meshed with the outer surface of gears 215 on the right side.

[0041] The dustproof component 22 includes an insulating rubber sleeve 222, which is disposed on the right side of several arc-shaped clamps 213. The outer ring of the insulating rubber sleeve 222 is connected to the inner wall of the wiring groove 112. Several push rods 223 are in contact with the inner wall of the insulating rubber sleeve 222. A rack 221 is welded to the side of the push rods 223 away from the inner wall of the insulating rubber sleeve 222.

[0042] Several racks 221 pass through the wiring groove 112 and extend into the limiting groove 212. The outer surfaces of several racks 221 are slidably connected to the inner wall of the limiting groove 212. The left side of several racks 221 is meshed with the outer surface of the gear 215.

[0043] The dustproof components 22 consist of two sets, each set being installed inside the wiring slot 112. Both sets contain identical components. When the cable is inserted into the wiring slot 112, the arc-shaped clamps 213 are pushed away from each other and stretch the annular spring 214. The rebound force of the annular spring 214 resets the arc-shaped clamps 213, bringing them into contact with the cable for auxiliary clamping and fixing. During this process, rack one 211 slides, driving gear 215 to rotate, which in turn drives rack two 221 to move closer together. Rack two 221 pushes push rod 223, causing the insulating rubber sleeve 222 to expand and fit against the cable surface. At this time, the insulating rubber sleeve can fill the gaps to prevent dust from entering the wiring slot, avoiding moisture and electrical conductivity, reducing the risk of leakage, and ensuring safe power transmission. Simultaneously, reducing dust contact can slow down equipment wear and corrosion, extending its service life.

[0044] The anti-loosening component 23 includes four cavities 232, which are set in pairs. The two sets of cavities 232 are respectively opened on the front and back sides of the right side inside the wire clamp body 111. The corresponding sides inside the two sets of cavities 232 are slidably connected to limit plates 231. Several springs 233 are connected to the sides of the two cavities 232 that are far apart from each other.

[0045] Several springs 233 are connected to the inner wall of the cavity 232 on the side away from the limiting plate 231. Rotating the fastening bolt 114 causes the opening of the clamp body 111 to shrink, and the anti-slip threaded sleeve 113 clamps and fixes the cylinder. During this process, the springs 233 in the cavity 232 are compressed and store force. At the same time, the springs 233 generate a rebound force to push the opening to expand. At this time, the clamp body 111 generates a counter-pushing force on the fastening bolt 114, so that it fits tightly against the surface of the clamp body 111 and remains taut. This design effectively prevents the fastening bolt from loosening, reduces the risk of the clamp body 111 falling off, and improves the stable use effect of the clamp body 111.

[0046] A specific application of this embodiment is as follows: In use, the wire clamp body 111 is first fixedly installed by placing the anti-slip threaded sleeve 113 onto the surface of the cylindrical body to be installed. Then, by rotating the fastening bolt 114, the openings on the right side of the wire clamp body 111 are brought closer together. During this process, the anti-slip threaded sleeve 113 is forced to contract and clamp the surface of the cylindrical body. Simultaneously, as the openings approach each other, the spring 233 is compressed by the cavity 232. The spring 233, then limited by the limiting plate 231, will... The clamp contracts and stores force, and at the same time, several springs 233 will perform a reset movement due to their own characteristics. The reset action of several springs 233 will cause the openings to move away from each other. At this time, the surface of the clamp body 111 will generate a certain counter-pushing force on the fastening bolt 114. At this time, the fastening bolt 114 will be tightly attached to the surface of the clamp body 111, and the fastening bolt 114 will always be in a taut state, reducing the possibility of the fastening bolt 114 loosening under external force, thereby reducing the possibility of the clamp body 111 falling off and improving the stable use effect of the clamp body 111.

[0047] After the clamp body 111 is fixed, the cable is connected. First, the cable is inserted into the wiring slot 112. At this time, the cable surface exerts a certain pushing force on several arc-shaped clamps 213. The arc-shaped clamps 213 will move away from each other under the force. At the same time, during the process of the arc-shaped clamps 213 moving away from each other, the ring spring 214 will be stretched. The ring spring 214 will generate a certain rebound force and drive the arc-shaped clamps 213 to reset. During the reset process, the arc-shaped clamps 213 will fit against the cable surface and clamp, providing a certain auxiliary clamping and fixing effect. At the same time, during the process of the arc-shaped clamps 213 moving away from each other, several racks 211 will move together. During the movement of the racks 211, they will slide inside the limiting groove 212. At the same time, during the process of the racks 211 moving away from each other, several gears 215 will rotate. At this time, the racks 221 will rotate through the gears 215. The components move closer together, and several racks 221 slide within the limiting groove 212. The limiting groove 212 provides a certain degree of limitation for the movement trajectory of racks 211 and 221. As the racks 221 move closer together, they drive several push rods 223 to move together. Simultaneously, as the push rods 223 move closer together, they push the insulating rubber sleeve 222 to expand. During the expansion of the insulating rubber sleeve 222, it adheres to the surface of the cable, thereby filling the gap between the cable and the wiring groove 112, achieving a certain dustproof effect, reducing dust from entering the wiring groove 112, keeping the inside of the wiring groove 112 clean and dust-free, effectively preventing dust from forming a conductive path due to moisture, reducing the risk of leakage, and ensuring the safety and stability of power transmission. At the same time, by preventing dust, the contact between dust and equipment can be reduced, reducing the rate of wear and corrosion, and extending the service life of the equipment. Then, the cable is clamped and fixed.
