[0023] 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.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a circuit breaker that is easy to assemble.

[0026] In this embodiment, refer to Figure 1-6 The easily assembled circuit breaker includes a circuit breaker housing 1, a connecting piece 2, a connecting strip 3, and fasteners 4; The connecting piece 2 is detachably mounted on the side wall of one side of the circuit breaker housing. The connecting piece is provided with a connecting groove 5, which extends through both ends of the connecting piece. The connecting strip 3 is detachably installed on the side wall of the circuit breaker housing opposite the connecting piece, and the connecting strip is inserted into the connecting groove. The connecting strip and the connecting piece are provided with series holes 6 on their sides. After the connecting strip is inserted into the connecting groove, the fastener passes through the series holes 6 to fix the connecting strip and the connecting piece.

[0027] In the above technical solution, a detachable connecting piece and connecting strip are installed on the side wall of the circuit breaker housing. Initial positioning is achieved through the insertion and engagement of the connecting groove and the connecting strip. Then, fasteners are used to fix the two together through the series holes, forming a stable splicing structure. This design decomposes the splicing function into two steps: insertion positioning and fastening locking. The connection between circuit breakers is achieved through the cooperation of the mechanical structures. This application provides a novel method for connecting circuit breakers, eliminating the need for additional complex adapters and enabling direct connection between circuit breakers. Detachable connecting pieces and strips allow users to freely choose to connect or use circuit breakers individually according to their actual needs, greatly improving flexibility. At the same time, the simplified connection steps significantly improve installation efficiency and reduce labor costs.

[0028] Specifically, the fastener is a tapered rod, and the series hole and the fastener are interference-fitted.

[0029] In this embodiment, the fastener is a tapered rod, and the series hole and the tapered rod are interference-fitted. During installation, the tapered rod is inserted into the series hole. Due to the tapered structure and interference characteristics, as the insertion depth increases, the compressive force between the tapered rod and the inner wall of the series hole increases, forming a tight connection. The fastening is achieved by relying on the elastic deformation of the material and friction.

[0030] Specifically, the fastener is made of elastic plastic.

[0031] In this embodiment, the fastener is made of elastic plastic. Utilizing the elastic deformation properties of elastic plastic, it deforms when inserted into the series hole, filling the internal space of the series hole and tightly fitting against the inner wall of the series hole. Fixing is achieved by relying on elastic restoring force and friction.

[0032] Specifically, both ends of the connecting piece and the connecting strip are integrally formed with fixing pieces 7, and the fixing pieces 7 are fixed to both ends of the circuit breaker housing by screws 8.

[0033] In this embodiment, the fixing plates integrally formed at both ends of the connecting piece and the connecting strip are fixed to the circuit breaker housing by screws, so that the connecting piece and the connecting strip are stably installed on the circuit breaker housing, forming a detachable fixed connection, which facilitates the disassembly and assembly of the connecting piece and the connector.

[0034] Specifically, the circuit breaker housing has concave surfaces 9 at both ends for accommodating fixing plates, and the depth of the concave surfaces 9 is greater than the thickness of the connecting plates.

[0035] In this embodiment, concave surfaces are provided at both ends of the circuit breaker housing to accommodate the fixing plates, and the depth of the concave groove is greater than the thickness of the connecting plate. This allows the connecting plate to be fully embedded in the concave surface after the fixing plate is installed, preventing the connecting plate from protruding from the surface of the circuit breaker housing and ensuring the flatness of the overall structure after splicing.

[0036] Specifically, a positioning concave surface 10 is provided on the bottom wall of the connecting groove located at the series hole, and a positioning protrusion 11 adapted to the positioning concave surface 10 is provided on the connecting strip.

[0037] In this embodiment, the positioning concave surface of the bottom wall of the connecting groove is adapted to the positioning convex edge on the connecting strip. During the process of inserting the connecting strip into the connecting groove, the positioning convex edge is embedded in the positioning concave surface to achieve precise positioning, restrict the lateral and longitudinal movement of the connecting strip in the connecting groove, and ensure that the connecting strip and the connecting piece are accurately connected.

[0038] Specifically, both the connecting groove and the connecting strip have a dovetail structure in cross-section.

[0039] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
