Description

Technical Field

[0001] This utility model relates to the field of circuit breakers, and in particular to a wiring structure for circuit breakers. 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. When a circuit experiences overload, short circuit, or undervoltage faults, the circuit breaker can automatically disconnect the circuit to prevent the accident from escalating and ensure the safe operation of the power system. It is suitable for overload and short circuit protection of DC and AC lines, and can also be used for infrequent line switching. It is widely used in various occasions such as industry, commerce, and residential buildings.

[0003] Before the circuit breaker can operate, it must first be connected and installed with the wiring terminals. The wiring process has the following drawbacks: 1) It is difficult to effectively arrange and limit the wiring during connection, resulting in a messy wiring distribution after installation. Furthermore, the wiring terminals need to be cut and stripped. Due to the lack of layout and positioning aids, it is difficult to neatly and uniformly cut and strip the wiring terminals. The inconsistent lengths of the wiring terminals and the poor overall neatness after interface installation pose safety risks when energized.

[0004] 2) Due to the limitations of the interface structure, the wiring must be installed sequentially in the forward direction, and it is impossible to complete the installation in one go, resulting in low installation efficiency. Since the spacing between the mounting holes is small, the installation will be affected by the obstruction of the wiring after installation on one side, making the installation operation more difficult.

[0005] 3) After the wiring is installed, it relies on the bolt structure at the interface for compression and support. However, there is a lack of effective support and fixation for the wiring ends, resulting in poor wiring connection stability. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a wiring structure for circuit breakers, which not only makes installation more convenient, but also allows for one-time installation, improving installation efficiency, and making the installation more orderly.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A wiring structure for a circuit breaker is installed on one side of the circuit breaker's wiring interface. The wiring structure includes a wiring support, and multiple conical cylindrical seats are provided at the rear of the wiring support. The number and position of the conical cylindrical seats correspond to the wiring interface. Each conical cylindrical seat has a wire core through hole in its center, and the wire core through hole passes through the wiring support. A fastening sleeve is threaded to the outer wall of each conical cylindrical seat, and the fastening sleeve clamps the conical cylindrical seat and the wiring.

[0009] The front of the cable support is fixed with a docking end seat, the number, position and size of which correspond to the wiring interface; during cable structure installation, the docking end seat and the wiring interface are plugged in and fitted together.

[0010] Both the conical cylinder seat and the fastening sleeve are conical.

[0011] The conical cylinder seat has multiple grooves circumferentially opened on its side wall.

[0012] The wire core perforations are concentrically distributed with the conical cylinder base.

[0013] Both sides of the front part of the cable support are provided with limit seats, which are frictionally locked with the side wall of the circuit breaker.

[0014] The inner side of the limiting seat is provided with a limiting block. After installation, the limiting block engages with the limiting slot on the side of the circuit breaker.

[0015] This utility model provides a wiring structure for circuit breakers, which has the following technical advantages:

[0016] 1) The cabling structure adopts a cabling end-mount type structure. The individual wiring is installed and positioned by the tapered cylindrical seats evenly distributed on the upper part of the cabling support. The cabling support provides a tight support and positioning. After installation, the cabling support shields the wire cores to avoid exposure, ensuring the neatness and safety of the wiring installation.

[0017] 2) During installation, the pre-support positioning of the cable tray is used as the positioning support structure for the wiring terminals. After the wiring terminals are uniformly cut and stripped, the cable tray and the tapered cylinder seat are used to pre-position and support the wiring terminals. By aligning and plugging the entire row, the parallel wiring terminals can be uniformly connected and installed on the circuit breaker in one go, which effectively reduces the difficulty of wiring installation and ensures the neatness of wiring installation.

[0018] 3) The conical base adopts a conical structure, which, together with the tightening sleeve, can securely clamp and fix different specifications of wiring. The structure is simple and easy to install. After installation, the auxiliary support of the conical base can improve the installation stability of the wiring terminal connection. In addition, the tightening sleeve can be independently tightened and disassembled. During later maintenance, individual wiring can be easily disassembled and reassembled as needed, which greatly improves the maintenance convenience of the device. Attached Figure Description

[0026] like Figure 1 As shown, a wiring structure for a circuit breaker is installed on one side of a circuit breaker 8 and used in conjunction with the circuit breaker 8. The wiring structure includes a wiring support 1 and a fastening sleeve 2, both of which can be made of fire-resistant plastic. For convenient wiring connection and installation, such as... Figure 5 As shown, a conical cylindrical seat 5 is provided at the rear of the cable support 1. The number and position of the conical cylindrical seats 5 are consistent with the number and position of the wiring interfaces 8.1 on the circuit breaker 8. For example, in this embodiment, there are three wiring interfaces 8.1 on the circuit breaker 8, and correspondingly, there are also three conical cylindrical seats 5. The three conical cylindrical seats 5 are evenly and uniformly fixed at the rear of the cable support 1. Both the conical cylindrical seat 5 and the fastening sleeve 2 are conical. To facilitate clamping deformation, grooves 5.1 are evenly provided on the conical side of the rear of the conical cylindrical seat 5. The grooves 5.1 are evenly opened circumferentially on the conical side of the rear of the conical cylindrical seat 5, which can improve the deformation capacity of the conical cylindrical seat 5 and facilitate the wiring clamping operation. To achieve a tight installation, as shown in the attached figure... Figure 4 As shown, an external thread is provided on the outer circumference of the conical cylindrical seat 5, and an internal thread is provided on the inner circumference of the fastening sleeve 2. The fastening sleeve 2 is fastened to the outside of the conical cylindrical seat 5 by the thread, and adopts a constricted clamping installation structure. The large diameter of the fastening sleeve 2 is 4-6 mm. With the tightening of the fastening sleeve 2, various specifications of wires can be securely clamped and fixed within a certain diameter range. The structure is simple and easy to install. Furthermore, the fastening sleeve 2 can be independently tightened and disassembled. During later maintenance, individual wires can be easily disassembled and reassembled as needed, greatly improving the maintenance convenience of the device.

[0027] like Figure 2 As shown, to facilitate positioning and installation with the circuit breaker 8, the front of the cable support 1 is evenly fixed with mating end seats 6 at equal intervals. Figure 1As shown, the mating end cap 6 is compatible with the wiring interface 8.1 at the bottom of the circuit breaker 8. After installation, the mating end cap 6 and the wiring interface 8.1 are aligned and fitted together. To facilitate the insertion and installation of the wire core through this cable structure, a wire core through hole 7 is provided at the front of the conical cylindrical base 5, as shown. Figure 4 As shown, the wire core through-hole 7 is a circular hole, and the wire core through-hole 7 is evenly spaced and opened in the middle of the cable support 1. The wire core through-hole 7 and the conical cylindrical seat 5 are distributed concentrically. The wire core through-hole 7 facilitates the wire core to pass through the cable support 1 and enter the wiring interface 8.1.

[0028] To facilitate the limiting installation of the cable support 1 and the circuit breaker 8, such as Figure 2-3 As shown, both sides of the front of the cable support 1 are provided with limiting side seats 3 for limiting installation with the circuit breaker 8. In order to achieve snap-fit ​​installation, a limiting block 4 is provided on the inner side of the limiting side seat 3. The limiting block 4 is snap-fitted into the limiting slot 8.2 provided on the side of the circuit breaker 8. The snap-fit ​​of the limiting slot 8.2 can perform preliminary installation limiting of the cable support 1 after docking to facilitate the tightening and locking operation of the wiring terminal.

[0029] Working principle and process:

[0030] 1) such as Figure 1 As shown, the circuit breaker 8 has three wiring interfaces 8.1. Before installation, the heads of the three sets of wiring terminals should be uniformly treated. Use a wire stripping tool to remove the wire insulation from the heads of the wiring terminals and uniformly leave 1-1.5 cm of bare wire core.

[0031] 2) Next, place the fastening sleeve 2 onto the upper part of the wiring and insert the wiring into the three conical cylinder seats 5 in sequence to ensure that the wiring is inserted in place. After installation, the ends of the three sets of wiring should be relatively flush. The wire core of the wiring end protrudes 0.8-1 cm from the wiring support 1. Then, tighten the fastening sleeve 2 to lock the wiring. Complete the connection and installation of multiple sets of wiring in the wiring mechanism (this device) in sequence.

[0032] 3) Subsequently, roughly tidy up the rear of the wiring, and then align the wiring end with the wiring interface 8.1 at the bottom of the circuit breaker 8 by holding the docking end 6. During installation, the docking end 6 is aligned and fitted with the wiring interface 8.1 at the bottom of the circuit breaker 8; at the same time, the limiting side seat 3 is engaged with the slot on the side of the circuit breaker to limit the wiring structure and the circuit breaker 8.

[0033] After completion, tighten the 8.3 screws to lock and limit the connection of the wire ends, thus completing the wiring installation.

[0034] 4) When it is necessary to disconnect the wiring, simply loosen the fastening screw 8.3 at the corresponding wiring point and loosen the fastening sleeve 2 on it to complete the installation and unlocking of the corresponding wiring. Then, pull out the wiring by pulling it out. After maintenance, strip the wire and reconnect the wiring to complete the installation operation.

[0035] In summary, this cabling structure adopts a cabling end-mount type structure. The individual wiring is installed and positioned by the conical cylindrical seats 5 evenly distributed on the upper part of the cabling support 1. The cabling support 1 provides a tight support and positioning. After installation, the cabling support 1 shields the wire core to avoid exposure, thus ensuring the neatness and safety of the wiring installation.

[0036] Furthermore, during installation, the pre-support positioning of the cable support 1 serves as a positioning support structure for the wiring terminals. After the wiring terminals are uniformly cut and stripped, the cable support 1, in conjunction with the conical cylinder seat 2, provides pre-positioning support for the wiring terminals. By aligning and plugging the entire row of wiring terminals, the parallel wiring terminals can be connected and installed in a single, unified manner, which can effectively reduce the difficulty of wiring installation.

[0037] The conical base 5 adopts a conical structure, which, together with the tightening sleeve 2, can securely clamp and fix wires of different specifications. The structure is simple and easy to install. After installation, the auxiliary support of the conical base 2 can improve the installation stability of the wire connection. In addition, the tightening sleeve 2 can be independently tightened and disassembled. During later maintenance, individual wires can be easily disassembled and reassembled as needed, which greatly improves the maintenance convenience of the device.
