Description

Technical Field

[0001] This invention relates to the field of parallel groove clamp technology, and in particular to a low-resistance parallel groove clamp and clamp mounting structure. Background Technology

[0002] In the construction, operation, and maintenance of power lines, parallel groove clamps are key components used to achieve electrical connections and mechanical fixation between cables. Their basic function is to reliably clamp two or more cables together, ensuring that current can pass through the connection point with low resistance and stability. They are important accessories for cable connections. Currently, common parallel groove clamps mainly rely on bolt tightening or wedge-shaped self-locking structures to achieve initial clamping. Bolt-tightening clamps generate pressure by tightening bolts, which is simple in structure but the pressure is easily affected by installation torque and subsequent thermal cycling. Wedge-shaped clamps, on the other hand, utilize the principle of inclined planes, and the wedges are tightened by tapping or pulling during installation, which has a certain degree of self-adaptability.

[0003] However, in the existing technical solutions mentioned above, the lines may experience wire creep or loosening due to factors such as load changes, ambient temperature fluctuations, and wind vibrations during operation. This can lead to a decrease in contact pressure between the clamp and the wire, and an increase in contact resistance. This can cause overheating at the connection point, increased power loss, and in severe cases, may even lead to melting or fire accidents. Existing parallel groove clamps cannot monitor the connection status in real time, requiring maintenance personnel to conduct regular inspections and manual tightening. This not only increases maintenance costs and workload, but also makes it difficult to guarantee the timeliness and safety of manual maintenance in some complex terrains, harsh environments, or important unattended sections. Therefore, there is an urgent need for an intelligent clamp structure that can sense the connection status in real time and automatically compensate for the clamping force when loosening occurs.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1As shown, a low-resistance parallel groove clamp and clamp mounting structure include a lower clamp plate 1, an upper clamp plate 2 snapped onto the upper surface of the lower clamp plate 1, a fixing pin 3 inserted into the center of the upper clamp plate 2, four through holes on the surface of the lower clamp plate 1, and four holes on the upper clamp plate 2. The width of the upper clamp plate 2 is one-quarter of the width of the lower clamp plate 1, and the through holes on the surface of the upper clamp plate 2 are coaxial with the through holes on the surface of the lower clamp plate 1. Figure 3 As shown, the fixing pin 3 is inserted into the through hole. Limiting holes 6 are opened on both sides of the surface of the fixing pin 3. When the fixing pin 3 is inserted into the through hole, it can lock the upper clamping plate 2 and the lower clamping plate 1. At this time, the upper clamping plate 2 moves towards the lower clamping plate 1 and clamps the wire harness placed between the upper clamping plate 2 and the lower clamping plate 1. like Figure 4 As shown, a return spring 4 is fixedly connected to the lower surface of the fixing pin 3, and a washer 5 is fixedly connected to the lower side of the return spring 4, as shown. Figure 5 As shown, a connecting post 10 is fixedly connected to the lower surface of the upper clamping plate 2. A metal contact 11 is provided on the upper surface of the lower clamping plate 1 near the connecting post 10. A circular groove is opened on the lower side of the lower clamping plate 1 below the connecting post 10. The metal contact 11 is attached to the inner wall of the circular groove. The connecting post 10 and the circular groove are located on the same vertical line. When the upper clamping plate 2 moves towards the lower clamping plate 1, the connecting post 10 can be inserted into the inside of the circular groove and connected with the metal contact 11 inside it to realize the circuit connection. Furthermore, during installation, the operator first places the wires to be connected side by side on the upper surface of the lower clamping plate 1. Then, the four upper clamping plates 2 are aligned with the corresponding through holes on the lower clamping plate 1 in sequence, and the fixing pins 3 are inserted from top to bottom into the corresponding through holes of the upper clamping plates 2 and the lower clamping plates 1. During the insertion process, the pad 5 at the bottom of the fixing pin 3 is pressed, the return spring 4 is compressed, and the fixing pin 3 drives the upper clamping plates 2 to move closer to the lower clamping plate 1, thereby initially pressing the wires. When the connecting post 10 is inserted into the circular groove of the lower clamping plate 1 and contacts the metal contact 11, an electrical connection path is formed, providing power conditions for subsequent triggering and transmission.

[0022] like Figure 4 As shown, the upper clamping plate 2 is equipped with a triggering mechanism 7 inside, such as... Figure 8As shown, the triggering mechanism 7 includes an air chamber 705. A movable plate 708 is slidably connected to the upper end of the air chamber 705. Top blocks 710 are slidably connected to the inner side walls at both ends of the movable plate 708. Horizontal grooves 709 are formed on the surfaces of both sides of the movable plate 708. The top blocks 710 are slidably connected to the inside of the horizontal grooves 709. A compression spring 711 is fixedly connected to the surface of the top block 710 located on the bottom side of the horizontal groove 709. A metal sheet is fixedly connected inside the top block 710. An internal power supply is fixedly connected inside the upper clamping plate 2. The internal power supply is an independent power supply, and an insulating cover made of rubber is fixedly connected to the outside of the internal power supply. The top block 710 is connected to the internal power supply through a wire. The top block 710 can move to the outside of the horizontal groove 709 under the action of the ejection spring 704. like Figure 8 As shown, contact blocks 712 are fixedly connected to both sides of the air cavity 705. The air cavity 705 is a T-shaped groove that is wider at the top and narrower at the bottom. A groove is opened in the lower half of the wider part at the top of the air cavity 705. The contact blocks 712 are fixedly connected inside the groove. The contact blocks 712 are connected to the connecting post 10 through wires. Furthermore, in the initial clamping state, the wire applies pressure to the contact plate 703 on the lower surface of the upper clamping plate 2, causing it to compress and push out the spring 704 and move into the movable groove 701. The elastic cavity 702 is compressed, and the gas inside is forced into the lower part of the air cavity 705, pushing the piston 706 and the movable plate 708 connected to it to move upward. During the upward movement of the movable plate 708, its outer surface is in contact with the upper side wall of the air cavity 705, and the circuit is in a disconnected state. When the upper clamping plate 2 and the lower clamping plate 1 loosen, the air inside the air cavity 705 enters the interior of the elastic cavity 702. When the movable plate 708 moves with the piston 706 to the lower end of the air cavity 705, the top block 710 moves to the outside of the transverse groove 709 under the elastic force of the compression spring 711, and its top end is in contact with the surface of the contact block 712 inside the groove, realizing the connection of the circuit.

[0023] like Figure 7 As shown, the air cavity 705 is opened inside the upper clamping plate 2. The upper clamping plate 2 has a movable groove 701 at the lower end of the air cavity 705. An elastic cavity 702 is fixedly connected inside the movable groove 701. A contact plate 703 is fixedly connected to the bottom of the elastic cavity 702. An ejector spring 704 is fixedly connected to the upper surface of the contact plate 703. The contact plate 703 is made of rubber. When the contact plate 703 comes into contact with the wire, the contact plate 703 is squeezed and moves into the movable groove 701. At this time, the contact plate 703 overcomes the elastic force of the ejector spring 704 and squeezes the elastic cavity 702. The elastic cavity 702 contracts, and the air inside it is discharged into the air cavity 705. like Figure 8As shown, a piston 706 is slidably connected to the lower end of the air chamber 705. The elastic chamber 702 is connected to the air chamber 705. The diameter of the piston 706 is the same as the diameter of the lower end of the air chamber 705. When the air in the elastic chamber 702 enters the air chamber 705, the air pressure inside the air chamber 705 increases, and the pressure pushes the piston 706 to move towards the upper end of the air chamber 705. like Figure 8 As shown, a support rod 707 is fixedly connected to the upper surface of piston 706, and a movable plate 708 is fixedly connected to the top of support rod 707. When the air pressure inside air chamber 705 increases, piston 706 moves upward, driving movable plate 708 to move upward through support rod 707. When the air pressure inside air chamber 705 decreases, piston 706 moves downward, driving movable plate 708 to move downward through support rod 707. Furthermore, if the wire becomes loose due to thermal expansion and contraction or vibration, the pressure on the contact plate 703 decreases, the ejector spring 704 pushes the contact plate 703 to reset, the elastic cavity 702 expands, and air is drawn from the air cavity 705, causing the air pressure in the air cavity 705 to drop. Under the action of the air pressure difference, the piston 706 drives the movable plate 708 to move down. When the movable plate 708 moves down to the lower side of the wider section of the air cavity 705, the top block 710 extends completely out of the transverse groove 709 under the action of the compression spring 711, and the metal plate at its end contacts the contact block 712 fixed in the groove on the side wall of the air cavity 705, thereby connecting the circuit composed of the internal power supply, the top block 710, the contact block 712, the connecting post 10 and the metal contact 11.

[0024] like Figure 2 As shown, the bottom of the lower clamping plate 1 is equipped with a transmission mechanism 8, such as... Figure 9 As shown, the transmission mechanism 8 includes a movable plate 806, a connecting rod 805 fixedly connected to the back of the movable plate 806, a movable connecting rod 804 rotatably connected to the end of the connecting rod 805 away from the movable plate 806, and a rotating shaft 803 rotatably connected to the end of the movable connecting rod 804 away from the connecting rod 805. Figure 13 As shown, a rack 801 is fixedly connected to the side of the rotating shaft 803. The surface of the rack 801 is provided with ratchet teeth, which are elastic gear teeth that rotate in one direction. The movement of the moving plate 806 drives the movable connecting rod 804 to rotate around the rotating shaft 803 through the connecting rod 805. The lateral thrust generated by the movable connecting rod 804 drives the rack 801 to move. like Figure 9As shown, a limiting block 802 is engaged inside the side wall of the rack 801. The limiting block 802 is fixedly connected to the lower surface of the lower clamping plate 1, allowing the rack 801 to slide along the surface of the limiting block 802. A sliding rod 807 is slidably connected inside the moving plate 806. A connecting spring 808 is wound around the surface of the sliding rod 807. An electromagnetic block 809 is fixedly connected inside the moving plate 806, and the metal contact 11 is connected to the electromagnetic block 809 through a wire. A fixing plate 810 is fixedly connected to the end of the sliding rod 807. The fixing plate 810 is fixedly connected to the lower surface of the lower clamping plate 1, fixing the sliding rod 807 to the lower surface of the lower clamping plate 1. At this time, the moving plate 806 can slide along the surface of the sliding rod 807. like Figure 10 As shown, the connecting spring 808 is located on the side close to the fixed plate 810. The moving plate 806 moves away from the fixed plate 810 under the action of the connecting spring 808. There are two moving plates 806, each with an electromagnetic block 809 fixedly connected inside. The near ends of the two electromagnetic blocks 809 are the same magnetic poles, so that the electromagnetic blocks 809 repel each other when energized, and the two moving plates 806 on both sides move in opposite directions. Furthermore, when the trigger mechanism 7 connects the circuit, the current flows through the metal contact 11 to the two electromagnetic blocks 809. After the two electromagnetic blocks 809 are energized, they generate magnetic fields of the same polarity, which repel each other. This repulsive force overcomes the tension of the connecting spring 808 and pushes the two moving plates 806 to move in opposite directions along the slide bar 807. The movement of the moving plate 806 is transmitted to the movable connecting rod 804 through the connecting rod 805 on its back. The movable connecting rod 804 rotates around the rotating shaft 803 and converts the linear motion of the moving plate 806 into the horizontal linear motion of the rack 801 along the limiting block 802.

[0025] like Figure 6 As shown, the lower clamping plate 1 is equipped with a locking mechanism 9 inside, such as... Figure 9 As shown, the locking mechanism 9 includes a rotating wheel 903. The side of the rotating wheel 903 meshes with a rack 801, and the rack 801 has ratchet teeth. When the rack 801 slides, it can drive the rotating wheel 903 to rotate clockwise. A lead screw 902 is fixedly connected to the center of the rotating wheel 903. A moving block 904 meshes with the surface of the lead screw 902. The moving block 904 is engaged inside the vertical groove 901, thereby limiting the movement of the moving block 904. Figure 11 As shown, a snap-fit ​​block 905 is rotatably connected inside the movable block 904. The snap-fit ​​block 905 snaps into the inside of the limiting hole 6 to fix the fixing pin 3. A vertical groove 901 is opened inside the lower clamping plate 1. The lead screw 902 is rotatably connected inside the vertical groove 901. When the lead screw 902 rotates with the rotating wheel 903, the movable block 904 moves downward along the surface of the lead screw 902. like Figure 12As shown, the snap-fit ​​block 905 is rotatably connected to the inside of the moving block 904 via a rotating shaft. A torsion spring 906 is fixedly connected inside the rotating shaft. Under the action of the torsion spring 906, the snap-fit ​​block 905 rotates away from the vertical groove 901. When the moving block 904 moves downward, the snap-fit ​​block 905 can drive the fixing pin 3 to move downward through snap-fit ​​with the limiting hole 6. The upper clamping plate 2 moves downward synchronously, enhancing the clamping of the wire harness.

[0026] Furthermore, the horizontal movement of the rack 801 drives the rotating wheel 903 meshing with it to rotate. The rotating wheel 903 drives the lead screw 902 at its center to rotate within the vertical groove 901. The moving block 904 meshing with the lead screw 902 is confined within the vertical groove 901 and can only move vertically. When the rack 801 moves to one side due to the repulsive force of the electromagnetic block 809, the rotating wheel 903 drives the lead screw 902 to rotate, causing the moving block 904 to move downward along the lead screw 902. The moving block 904 drives the locking block 905 at its end to move downward. The locking block 905, in a torsional motion... Under the action of spring 906, the claws are kept in an outward-open state. During the downward movement, the claws are inserted into the limiting holes 6 on both sides of the fixing pin 3 and push the fixing pin 3 to move down as a whole. The downward movement of the fixing pin 3 causes the upper clamping plate 2 to press further down the lower clamping plate 1, thereby automatically compensating for the reduced clamping force due to the loosening of the wire and re-clamping the wire. When the wire is re-clamped, the trigger mechanism 7 is reset, the circuit is disconnected, the electromagnetic block 809 is demagnetized, and under the tension of the connecting spring 808, the moving plate 806, rack 801, rotating wheel 903 and other components are reset, preparing for the next loosening action response.

[0027] Working principle: After initial installation and clamping of the wire, the snap-fit ​​block 905 engages with the limiting hole 6 of the fixing pin 3, fixing the upper clamping plate 2 and the lower clamping plate 1. The wire presses against the contact plate 703, and the triggering mechanism 7 is in a high-position disconnected state. The transmission mechanism 8 and the locking mechanism 9 do not operate. When the wire becomes loose, the pressure on the contact plate 703 decreases, and it resets under the action of the ejector spring 704. This causes the elastic cavity 702 to expand and the air pressure in the air cavity 705 to drop. The piston 706 and the movable plate 708 move downward. When the movable plate 708 moves to the lower side of the wider section of the air cavity 705, the top block 710 inside it extends under the action of the compression spring 711. When the contact block 712 is in contact, the circuit is connected. After the circuit is connected, the current flows to the two electromagnetic blocks 809 of the transmission mechanism 8. The two generate a repulsive force, which drives the two moving plates 806 to move back and forth. The movement of the moving plates 806 is converted into the horizontal movement of the rack 801 through the connecting rod 805 and the movable connecting rod 804. The rack 801 drives the rotating wheel 903 of the locking mechanism 9 to rotate, which in turn drives the lead screw 902 to rotate, causing the moving block 904 to move downward along the vertical groove 901. When the moving block 904 moves downward, the locking block 905 pushes the fixing pin 3 and the upper clamping plate 2 connected to it to press down as a whole, thereby automatically increasing the clamping force on the wire and eliminating loosening.

[0028] When the wire is re-clamped, the trigger mechanism 7 is reset due to the contact plate 703 being pressed again, the circuit is broken, and the entire system returns to the initial standby state under the action of elastic elements such as the reset spring 4 and the connecting spring 808. This process realizes automatic monitoring and compensation of the clamping force of the wire clamp, ensuring the long-term stability and low resistance characteristics of the connection.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
