Description

Technical Field

[0001] This utility model relates to the field of circuit breaker clamp technology, specifically a circuit breaker clamp. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Traditionally, vacuum circuit breakers used in high-voltage power transmission and distribution fields or 35kV and below lines are connected to the terminals of the vacuum circuit breaker using clamps.

[0003] When using wire clamps to connect circuit breaker terminals, the number of cables to be connected is generally one or two. Existing wire clamps come in two different types: single-clamp and double-clamp. This forces workers to determine the exact number of cables to be connected before installation and then select the appropriate type of clamp. The limited versatility of these wire clamps negatively impacts and reduces the efficiency of the installation work.

[0004] Therefore, this utility model proposes a wire clamp for circuit breakers. Utility Model Content

[0005] The purpose of this utility model is to provide a wire clamp for circuit breakers to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a wire clamp for circuit breakers, including a connecting plate, a set of clamping cylinders I at the end of the connecting plate, a set of clamping cylinders II on both sides of the clamping cylinders I, bolts inside the set of clamping cylinders I and the set of clamping cylinders II, and the end of the connecting plate being fixedly connected to the bottom of the clamping cylinders I.

[0006] Preferably, a slide bar is provided above the second clamping cylinder and fixedly connected thereto, and the slide bar is located inside the first clamping cylinder and slidably connected thereto.

[0007] Preferably, both clamping cylinder one and clamping cylinder two have multiple grooves inside, and the direction of the multiple grooves is the same as that of the connecting plate and they are equidistantly distributed.

[0008] Preferably, the upper part of the connecting plate includes a plurality of recesses for placing cable ends.

[0009] Preferably, the side of the connecting plate is provided with a box, and the box is rotatably connected to the connecting plate through a rotating shaft.

[0010] Preferably, the box body has a rubber block inside, and the rubber block has multiple arc-shaped grooves inside.

[0011] This utility model has at least the following beneficial effects:

[0012] In this invention, workers can adapt the installation to the number of cables to be connected. When only a single cable needs to be installed, the bolts inside one set of clamps can be removed, and the bolts inside the two sets of clamps can be tightened to bring the two sets of clamps and one set of clamps closer together, ultimately achieving a secure connection for the single cable. When two cables need to be connected, the bolts inside the two sets of clamps can be removed, and the bolts inside the first set of clamps can be tightened to clamp the two sets of clamps together, achieving a secure connection for the two cables. Furthermore, the gap between the two sets of clamps and the first set can be freely slid to accommodate different spacing requirements for connecting two cables, making this clamp more versatile. Compared to existing technologies, workers no longer need to confirm and select the appropriate type of clamp before connection, improving the clamp's versatility and increasing the efficiency and convenience of installation work.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a wire clamp for a circuit breaker, comprising:

[0020] Example

[0021] The connecting plate 1 has a set of clamping cylinder 2 at its end. A set of clamping cylinder 3 is provided on both sides of the clamping cylinder 2. Bolts 4 are provided inside the clamping cylinder 2 and the two sets of clamping cylinder 3. Tightening and loosening the bolts 4 can make the clamping cylinder 2 and the two sets of clamping cylinder 3 move closer and further away from each other, thereby achieving the clamping and loosening of the cable. The end of the connecting plate 1 is fixedly connected to the bottom of the lower cylinder in a set of clamp cylinder 1 2. A sliding strip 5 is provided above the clamp cylinder 2 3 and fixedly connected thereto. The sliding strip 5 is located inside the clamp cylinder 1 2 and is slidably connected thereto. The upper part of the connecting plate 1 includes multiple recesses 7 for placing the cable end. The cable end can pass through the clamp cylinder 1 2 and the clamp cylinder 2 3 and be placed directly above the connecting plate 1, which helps to improve the stability of the bolt 4 fixing the cable. The interior of the clamp cylinder 1 2 and the clamp cylinder 2 3 is provided with multiple grooves 6. The direction of the multiple grooves 6 is the same as that of the connecting plate 1 and is equidistant. The grooves 6 and the protruding area on the surface of the cable interlock with each other, which can increase the friction between the surface of the cable and the inner wall of the clamp cylinder 1 2 and the clamp cylinder 2 3, ensuring a stable connection effect.

[0022] Working principle:

[0023] During the circuit breaker cable connection process, operators can adapt the installation based on the number of cables to be connected. For example, when only a single cable needs to be installed, the bolts 4 inside one set of clamps 2 can be removed, and the cable can be threaded between the two clamps 2, finally placing the cable end into the recess 7. Then, the operator can tighten the bolts 4 inside the two sets of clamps 3, bringing the two sets of clamps 3 and one set of clamps 2 closer together, thus achieving a secure connection for the single cable. Similarly, when two cables need to be connected, the bolts 4 inside the two sets of clamps 3 can be removed, and the tightening effect of the bolts 4 inside clamps 2 can clamp the two sets of clamps 3 together, achieving a secure connection for the two cables. Furthermore, the spacing between the two sets of clamps 3 and clamps 2 can be freely slid to accommodate different spacing requirements for dual-cable connections, making this clamp more versatile. Compared to existing technologies, this new technology eliminates the need for staff to first confirm and select the appropriate type of wire clamp for connection, thus improving the versatility of the wire clamp and enhancing the efficiency and convenience of installation work for staff.

[0024] Both clamp 12 and clamp 23 have a cover plate 11 on their outer walls and are slidably connected to it. With the bolt 4 inside clamp 12 and clamp 23 removed, the cover plate 11 can be slid by the staff to cover the socket, thereby ensuring the sealing of the cable connection area.

[0025] In addition, a box 8 is provided on the side of the connecting plate 1. The box 8 is rotatably connected to the connecting plate 1 via a pivot. A rubber block 9 is provided inside the box 8 and is fixedly connected to it. The rubber block 9 has multiple arc grooves 10 inside. After the connection is completed, the staff can rotate the box 8 to wrap the end of the cable to prevent damage to the cable from natural factors. At the same time, the insulating rubber block 9 can also better protect the surface of the cable. The arc grooves 10 of the rubber block 9 can cooperate with the recessed part 7 to squeeze the cable more firmly and ensure its good stability.
