Description

Technical Field

[0001] This application relates to the technical field of power-connecting clamps, and in particular to a lightweight bus clamp and its usage method. Background Technology

[0002] In low-voltage power supply protection operations, the rapid and reliable connection of the busbar is a key link to achieve simultaneous grid connection. As a core connection device, the adaptability, ease of operation and safety performance of the busbar clamp directly affect the work efficiency and construction safety.

[0003] Currently, the busbar clamps widely used in the industry are mainly of the "L-shaped" structure, which has obvious limitations in practical applications. On the one hand, for scenarios such as some JP cabinets where the gap between the B phase and A / C phase copper busbars is only 26mm or even smaller, the structural design of the "L-shaped" clamp makes it impossible to meet the access requirements of narrow gaps of 20mm-40mm, making it difficult to adapt to such special layout power distribution equipment. On the other hand, when facing the busbars of vertically arranged distribution cabinets, the "L-shaped" clamp cannot achieve a direct plug-in connection, making the operation process cumbersome and prolonging the operation time.

[0004] Meanwhile, some existing bus clamps require considerable hand strength to generate sufficient clamping force, which can lead to excessive physical exertion for construction workers during long-term operation and affect operational stability; furthermore, the rated voltage, current, peak withstand current, and other safety parameters of some products do not fully meet the stringent requirements of low-voltage power supply operations, posing safety hazards.

[0005] Therefore, the industry urgently needs a compact, easy-to-operate bus clamp that can adapt to narrow-gap copper busbar and vertical busbar connection scenarios, and has reliable safety performance, in order to solve the shortcomings of existing technologies and meet the diverse access needs in low-voltage power supply operations. Summary of the Invention

[0006] To address at least one of the aforementioned technical problems, this application provides a lightweight manifold clamp and its usage method.

[0007] In a first aspect, this application provides a lightweight bus clamp, which adopts the following technical solution:

[0008] A lightweight manifold clamp includes a clamping assembly and an insulating clamp rod. One end of the insulating clamp rod is provided with a threaded push rod. The clamping assembly includes a manifold chuck that is threadedly connected to the threaded push rod, and a clamping member that is controlled by the axial push of the threaded push rod to form a clamping action with the manifold chuck. The clamping member is mounted on the manifold chuck via a linkage structure.

[0009] The threaded push rod passes through the manifold chuck and can abut against the clamping member. The threaded push rod is perpendicular to the clamping direction of the clamping member, and the clamping member is on the movement path of the threaded push rod throughout the entire movement process.

[0010] The bus clamp is provided with a threaded connection hole for cable connection.

[0011] In one embodiment: the manifold chuck has a flat cuboid structure, the manifold chuck has a mounting cavity that extends through both end faces, and the side of the manifold chuck opposite to the threaded push rod has a clamping opening.

[0012] In one embodiment: the linkage structure includes multiple connectors, one end of which is rotatably connected to the manifold clamp and the other end is rotatably connected to the clamping member, and the connectors are arranged in parallel.

[0013] In one embodiment: the end of the threaded push rod is provided with a connecting pull head, and the clamping member is provided with a sliding groove for connecting the pull head, the sliding groove being opened along the clamping direction of the clamping member.

[0014] In one embodiment: the end of the slide facing the clamping end face of the clamping member is provided with an opening for inserting the connecting pull head. When the clamping member is in a non-clamping state, the opening is located on the moving path of the connecting pull head.

[0015] In one embodiment: the connecting pull head is a connecting bolt installed at the end of the threaded push rod, and the nut of the connecting bolt is spaced apart from the end of the threaded push rod.

[0016] In one embodiment: the bus clamp is provided with a magnetic element for adsorbing the clamping element in a non-clamping state.

[0017] In one embodiment: the insulating clamp includes an insulating rod connected at one end to a threaded push rod, and a handle inserted into the other end of the insulating rod; a hinge joint is provided between the insulating rod and the handle, one end of the hinge joint is fixedly connected to the insulating rod or the handle, and the other end of the hinge joint is circumferentially fixed and axially slidingly connected to the handle or the insulating rod.

[0018] In one embodiment: the side of the manifold clamp that mounts the threaded push rod is provided with a connecting plate, and the threaded connection hole is provided on the connecting plate.

[0019] Secondly, this application provides a method for using a lightweight bus clamp, employing the following technical solution:

[0020] A method for using a lightweight bus clamp includes the following steps:

[0021] Reset: The movable clamping component allows the magnetic component to hold the clamping component in a non-clamping state;

[0022] Assembly: Install the threaded push rod of the insulating clamp rod onto the manifold clamp until the threaded push rod abuts against the clamping part and pushes the clamping part to move, so that the connecting pull head engages with the slide groove;

[0023] Power connection: Secure the cable to the threaded connection hole using fixing bolts;

[0024] Clamping: Place the bus clamp in the clamping position, rotate the insulating clamp rod to drive the threaded push rod to rotate on the bus clamp, and push the clamping parts to move until clamping is completed.

[0025] In summary, this application has the following beneficial effects:

[0026] 1. The clamping component is connected by a linkage structure, and the clamping is achieved by pushing the threaded push rod on the insulating clamping rod. This allows for both a direct insertion connection of the bus clamp and a threaded connection for clamping, which is labor-saving and provides stable clamping. Furthermore, horizontal copper busbars can be directly clamped onto the screw for subsequent operations.

[0027] 2. The structure of clamping by connecting rod drives the clamping component, which allows the thickness of the manifold chuck to be smaller, while ensuring strength and meeting the access requirements of narrow gaps of 20mm-40mm.

[0028] 3. Power is connected only through the bus clamp. The insulating clamp provides good insulation performance and can meet the requirements of rated voltage and current of 1000V / 630A and peak withstand current ≥55KA, ensuring safe and reliable power supply operation.

Detailed Implementation

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Example 1: A lightweight bus clamp, such as Figure 1 and Figure 2 As shown, it includes a clamping assembly 100 and an insulating clamping rod 200, one end of which is provided with a threaded push rod 300.

[0039] The clamping assembly 100 includes a manifold 110 and a clamping member 120. The manifold 110 has a flat rectangular structure and a mounting cavity 130 that extends through both end faces. The manifold 110 has a clamping port 140 on the side opposite to the threaded push rod 300. The opening 122 of the clamping port 140 is smaller than the mounting cavity 130, so that the manifold 110 forms a C-shaped structure as a whole.

[0040] A threaded hole is provided on one side of the manifold 110. The threaded hole passes through the side of the manifold 110 and communicates with the mounting cavity 130. The threaded push rod 300 is threadedly connected to the threaded hole.

[0041] The clamping member 120 is mounted on the manifold 110 via a connecting rod structure 400. The connecting rod structure 400 includes multiple connecting members 410. In this embodiment, two connecting members 410 are provided. One end of the connecting member 410 is rotatably connected to the manifold 110, and the other end is rotatably connected to the clamping member 120. The connecting members 410 are arranged in parallel.

[0042] The threaded push rod 300 passes through the manifold 110 and abuts against the clamping member 120. The axial movement of the threaded push rod 300 can push the clamping member 120 to swing, and the swinging can form a clamping with the manifold 110.

[0043] The threaded push rod 300 is perpendicular to the clamping direction of the clamping member 120, and the clamping member 120 is on the movement path of the threaded push rod 300 throughout the entire movement.

[0044] The bus clamp 110 has a connecting plate 150 on one side of the threaded push rod 300. The connecting plate 150 is located on the side with the threaded hole. The connecting plate 150 has an L-shaped structure and a threaded connection hole 160 on the connecting plate 150. The threaded connection hole 160 is located on the outside of the insulating clamp rod 200 and is used for cable connection.

[0045] Example 2: As Figure 3 , Figure 4 and Figure 5 As shown, the difference from Embodiment 1 is that the end of the threaded push rod 300 is provided with a connecting pull head 310, which is a connecting bolt installed at the end of the threaded push rod 300, and the nut of the connecting bolt is spaced apart from the end of the threaded push rod 300.

[0046] The clamping member 120 is provided with a groove 121 for connecting the pull head 310. The groove 121 is opened along the clamping direction of the clamping member 120.

[0047] The slide groove 121 has an opening 122 at one end facing the clamping end face of the clamping member 120 for inserting the connecting pull head 310. When the clamping member 120 is in a non-clamping state, the opening 122 is located on the moving path of the connecting pull head 310.

[0048] The manifold 110 is provided with a magnetic element 500 for adsorbing the clamping element 120 in a non-clamping state. The magnetic element 500 is embedded in the inner wall of the mounting cavity 130.

[0049] The method of using the lightweight bus clamp in this embodiment includes the following steps:

[0050] Reset: The movable clamping member 120 is moved so that the magnetic member 500 attracts the clamping member 120 and keeps it in a non-clamping state;

[0051] Assembly: Install the threaded push rod 300 of the insulating clamp rod 200 to the manifold 110 until the threaded push rod 300 abuts against the clamping member 120 and pushes the clamping member 120 to move, so that the connecting pull head 310 engages with the slide groove 121;

[0052] Power connection: Secure the cable to the threaded connection hole 160 using fixing bolts;

[0053] Clamping: Place the bus clamp 110 in the clamping position, rotate the insulating clamp rod 200 to drive the threaded push rod 300 to rotate on the bus clamp 110, and push the clamping member 120 to move until clamping is completed.

[0054] Example 3: As Figure 6 As shown, the difference from Embodiment 1 is that the insulating clamp 200 includes an insulating rod with one end connected to the threaded push rod 300 and a handle inserted into the other end of the insulating rod.

[0055] A hinge joint 600 is provided between the insulating rod and the handle. Through the hinge joint 600, the handle and the insulating rod can be rotated at an angle when needed, making it easier to control the rotation of the insulating rod through the handle.

[0056] One end of the hinge joint 600 is fixedly connected to the insulating rod or the handle, and the other end of the hinge joint 600 is circumferentially fixed and axially slidingly connected to the handle or the insulating rod. In this embodiment, the hinge joint 600 is fixedly connected to the handle.

[0057] The hinge joint 600 has a polygonal connecting post 610 at one end for sliding connection, and is connected to the insulating rod through the connecting post 610.

[0058] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
