Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and in particular to a distribution box with plug-in quick-change components. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection.

[0003] A household electrical distribution box is typically mounted inside a wall and contains circuit breakers that control power to various areas. Traditionally, the box has only a fixed bracket, onto which the circuit breakers are snapped. Cables are directly clamped to the top and bottom of the circuit breakers. This fixed circuit breaker arrangement is relatively slow to replace, and wiring errors are prone to poor contact. Summary of the Invention

[0004] To address the above-mentioned problems, the present invention discloses a distribution box for pluggable quick-change components, comprising a box body, a fixing plate disposed within the box body, a lower fastener and an upper fastener fixedly connected to the front face of the fixing plate, the lower fastener and the upper fastener being arranged in a bottom-up orientation, a sub-circuit breaker and a main circuit breaker disposed between the lower and upper fasteners, the sub-circuit breaker and the main circuit breaker both having convex edges at their lower and upper ends, the convex edges being respectively pressed by the lower fastener and the upper fastener. That is, the sub-circuit breaker and the main control switch are fixed to the fixing plate by a plug-in fastening method, facilitating quick replacement.

[0005] The back of the splitter is provided with contacts, and the back of the fixed plate is fixedly connected with a number of copper bridges, and the copper bridges are U-shaped, both ends of the copper bridges pass through the fixed plate, and one end of the copper bridges is in contact with the contacts, and the other end is threaded with a screw, and the upper end of the splitter is provided with a socket, and a copper busbar is provided above the splitter, and a number of branch plug-in terminals are provided on one side of the copper busbar, and the branch plug-in terminals are matched with the socket. The splitter is redesigned here, that is, the plug-in terminals and the copper busbar on the splitter are fixed by plugging, and the contacts on the back plate of the splitter are fixedly connected to the copper bridges. In this way, the splitter does not need to be directly connected to the splitter when replacing it, which has the advantage of fast replacement speed.

[0006] Preferably, the end of the lower fastener is fixedly connected to a plate, and a pry hole is provided on the plate. Since the splitter switch and the copper bridge are connected by contact, it is necessary to ensure that the splitter switch is firm, so the lower fastener and the upper fastener need to be designed to be more firm. At this time, it is not easy to remove the splitter switch that has been fixed, so a pry hole is provided. The end of the screwdriver is inserted into the pry hole and pressed against the preset slot of the fixing plate, and pried downward to make the lower fastener bend downward, thereby making the lower fastener disengage from the pressure on the lower convex edge of the splitter switch and can be removed. This method also prevents the splitter switch from being removed at will.

[0007] Preferably, the box includes a housing, the inner wall of which is provided with a second connecting column, and bolts are inserted through the four corners of the fixing plate, and the bolts are threadedly engaged with the second connecting column to secure the fixing plate. The gap between the second connecting column, the fixing plate, and the inner wall of the housing provides space for the copper bridge.

[0008] Preferably, the side wall of the housing is provided with a plurality of threading holes, which are reserved for cables to pass through the interior of the housing, and baffles are provided on the holes, which can be removed to fully expose the holes.

[0009] Preferably, a first connecting column is provided inside the housing, a front shell is provided at the front end of the housing, a bolt is inserted through the front shell, and the bolt is threadedly engaged with the first connecting column to fix the front shell.

[0010] Preferably, an opening is provided in the middle of the front shell, and the sub-circuit breakers and the main circuit breaker are exposed from the opening, and a cover is rotatably connected to the front of the front shell. This facilitates the operation of the main circuit breaker and the sub-circuit breakers while shielding the cables inside the shell, improving electrical safety.

[0011] Preferably, the upper part of the fixing plate is fixedly connected with a support plate, and the copper busbar is fixed on the support plate. It is used to fix the copper busbar, and the copper busbar is provided with two wires, namely the bell wire and the live wire.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. A fixing plate is provided inside the box body, and a lower fastener and an upper fastener are provided on the fixing plate, which has the advantage of fast replacement of the spacer.

[0014] 2. The upper end of the circuit breaker and the copper busbar adopt a plug-in electrical connection, while the upper end of the circuit breaker and the copper bridge adopt a contact electrical connection. After the circuit breaker is fixed, the electrical connection is realized, which is not only fast but also ensures the stability of the power connection. BRIEF DESCRIPTION OF THE DRAWINGS
