A copper busbar adapter cable expansion assembly

Abstract

This utility model relates to the field of circuit breaker technology, specifically a copper busbar adapter cable extension assembly, including a circuit breaker and a terminal block. The circuit breaker has a connecting groove on its surface, and the terminal block is bolted into the connecting groove. A movable plate is movably connected to the surface of the terminal block, and a wiring plate is movably connected to the end of the movable plate away from the terminal block. This utility model, through the connection between the circuit breaker and the connecting groove, achieves a connection support effect for the terminal block on the circuit breaker. Through the connection between the terminal block and the movable plate, and the connection between the movable plate and the wiring plate, the wiring plate facilitates connection when the cable lug is wider than the connecting groove. Furthermore, the staggered distribution of the terminal block and wiring plate on the connecting groove increases electrical clearance. The overlap width at the end overlapping with the switch terminal is equal, expanding the terminal block width by 1.5 times, thereby increasing current carrying capacity and reducing temperature rise.

Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a copper busbar adapter cable extension assembly. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and can close, carry, and interrupt current under abnormal circuit conditions within a specified time.

[0003] When connecting a circuit breaker to a cable, the connection between the circuit breaker and the cable is completed by connecting the copper busbar at the wiring terminal on the circuit breaker. However, when connecting the copper busbar on an existing circuit breaker, the working size of the copper busbar is fixed, and the connection cannot be performed when the cable lug is wider than the circuit breaker terminal and its matching wiring copper busbar. Utility Model Content

[0004] The purpose of this utility model is to provide a copper busbar adapter cable extension assembly to solve the problem mentioned in the background art that the copper busbar has a fixed working size and cannot be used for connection operations when the cable lug is wider than the circuit breaker terminal and its matching wiring copper busbar.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar adapter cable extension assembly, including a circuit breaker and a terminal block. The surface of the circuit breaker is provided with a connecting groove, and the terminal block is bolted to the inside of the connecting groove. A movable plate is movably connected to the surface of the terminal block, and a wiring plate is movably connected to the end of the movable plate away from the terminal block.

[0006] Preferably, the terminal block, movable plate, and wiring block are arranged in a "Z" shape.

[0007] Preferably, the terminal block and wiring block are arranged in three groups at one end of the circuit breaker.

[0008] Preferably, the adjacent terminal blocks and wiring blocks are distributed in opposite directions.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By connecting the circuit breaker and the connecting slot, and then connecting the connecting slot and the terminal block, the terminal block is supported on the circuit breaker. Through the connection of the terminal block and the movable plate, and the connection of the movable plate and the wiring plate, the connection is facilitated when the cable lug is wider than the connecting slot. The terminal block and the wiring plate are staggered on the connecting slot to increase the electrical clearance. The overlap width of the end that overlaps with the switch terminal is equal, expanding the terminal block width by 1.5 times, thereby increasing the current carrying capacity and reducing the temperature rise.

[0016] 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.

[0017] Please see Figure 1-4 One embodiment provided by this utility model:

[0018] A copper busbar adapter cable extension assembly includes a circuit breaker 1 and a terminal block 2. The surface of the circuit breaker 1 has a connecting groove 11. The terminal block 2 is bolted to the inside of the connecting groove 11. A movable plate 21 is movably connected to the surface of the terminal block 2. A terminal block 22 is movably connected to the end of the movable plate 21 away from the terminal block 2. Through the connection between the circuit breaker 1 and the connecting groove 11, the terminal block 2 is supported on the circuit breaker 1. Through the connection between the movable plate 21 and the terminal block 22, the connection of the terminal block 22 facilitates the connection of the cable.

[0019] Furthermore, the terminal block 2, the movable plate 21, and the wiring plate 22 form a "Z" shape. The terminal block 2 and the wiring plate 22 are distributed in three groups at one end of the circuit breaker 1. The adjacent terminal blocks 2 and wiring plates 22 are distributed in opposite directions. The connection between the terminal block 2 and the movable plate 21, and the connection between the movable plate 21 and the wiring plate 22, increases the electrical clearance when the adjacent terminal blocks 2 and wiring plates 22 are distributed in opposite directions, thereby increasing the current carrying capacity and reducing the temperature rise.

[0020] Working principle: When installing terminal block 2, it is installed in the connecting groove 11 by bolts. With the help of terminal block 22, it is convenient to connect the cable lug when it is wider than the connecting groove 11. The terminal block 2 and terminal block 22 are staggered on the connecting groove 11 to increase the electrical clearance and improve the application range and performance of terminal block 22.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
