[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a busbar, including a main housing 1 and a side housing 2 installed on one side of the main housing 1. The materials of the main housing 1 and the side housing 2 are both insulating plastics. Limiting grooves 13 are provided inside both the main housing 1 and the side housing 2. The limiting grooves 13 are used to limit the C-shaped copper piece 8 to prevent the C-shaped copper piece 8 from shifting. The C-shaped copper piece 8 is installed inside the limiting groove 13. An upper extension part 5 is provided at the top of the main housing 1. A plurality of upper wiring holes 6 are provided through the upper extension part 5 at equal intervals. The upper wiring holes 6 correspond to adjacent upper pins 83. A lower extension part 7 is provided on one side of the side housing 2. A lower wiring hole 4 is provided through the lower extension part 7. The lower wiring hole 4 corresponds to an adjacent lower pin 85. When the busbar is connected to an external device, such as an external device like a circuit breaker, during wiring, the wire first passes through the upper wiring hole 6 or the lower wiring hole 4 and then is connected to the external device. At this time, the upper extension part 5 or the lower extension part 7 can play an insulating protection role, avoiding too small an electrical clearance between the wire and the C-shaped copper piece 8, resulting in failures and improving safety.

[0022] Among them, the C-shaped copper piece 8 includes a main copper piece 81. Upper copper pieces 82 and lower copper pieces 84 are respectively arranged at the top and bottom of the main copper piece 81. By providing the main copper piece 81, the upper copper pieces 82 and the lower copper pieces 84 to form an upper and a lower layer, both can be connected to external devices to meet the usage requirements of different customers. A plurality of upper pins 83 are provided at the bottom of the upper copper piece 82. One end of the lower copper piece 84 is provided with a lower pin 85. The lower pin 85 and the upper pin 83 are used to connect to external devices, such as external devices like circuit breakers.

[0023] Among them, the main copper piece 81, the upper copper piece 82, the upper pin 83, the lower copper piece 84 and the lower pin 85 are of an integrally stamped and formed structure. Integrally stamping and forming not only has high production efficiency, convenient processing, but also low production cost.

[0024] Among them, a buckle 9 is provided on the side housing 2. An inclined block 12 matched with the buckle 9 is provided on the outer side of the main housing 1. The inclined block 12 and the buckle 9 cooperate to fix the side housing 2 on the main housing 1.

[0025] Among them, a baffle 3 is installed on the inner side of the main housing 1. The baffle 3 is used to shield the inner side of the main housing 1 to prevent impurities from entering the main housing 1. A clamping block 11 is provided on the baffle 3. A clamping groove 10 matched with the clamping block 11 is provided on the main housing 1. The clamping groove 10 and the clamping block 11 cooperate to fix the baffle 3 on the main housing 1.

[0026] Specifically, during use, the upper pin 83 and the lower pin 85 are inserted into the circuit breaker interface for connection. When wiring the circuit breaker, the wire first passes through the upper wiring hole 6 or the lower wiring hole 4 and then is connected to the circuit breaker. The upper extension part 5 or the lower extension part 7 can play an insulating and protective role for the wire, ensuring that there is sufficient electrical clearance between the wire and the upper pin 83 or the lower pin 85, thereby improving safety.
