Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a modular low-voltage plug-in tapping box. Background Art

[0002] With the continuous development of the cableization process of the distribution network, when independent loads with small capacities are concentrated, cable tapping boxes have become an effective means to achieve multi-branch connections of cables. The main function of a cable tapping box is to tap or transfer cables to meet the needs of different loads.

[0003] However, most of the existing cable tapping boxes usually adopt a fixed configuration. Their internal structure mainly consists of a simple box plus the distribution of basic electrical components, and parallel connections are achieved through wires or copper bars. Although this design has a low cost and a simple structure, when it is necessary to add or adjust the tapping circuit, it is often necessary to replace the tapping box as a whole or carry out a major transformation, which not only increases the difficulty of upgrading but also raises the cost. Summary of the Utility Model

[0004] In order to solve the problem that traditional cable tapping boxes usually have a fixed configuration and are not easy to expand or adjust, and if it is necessary to add or modify the tapping circuit, it may be necessary to replace the tapping box as a whole or carry out a major transformation, the present application provides a modular low-voltage plug-in tapping box.

[0005] The modular low-voltage plug-in tapping box provided by the present application adopts the following technical solutions:

[0006] A modular low-voltage plug-in tapping box includes a box body. A bracket is arranged inside the box body. A plurality of guide rail plates are arranged on the bracket. A tapping component is arranged inside the adjacent two guide rail plates on the bracket. The tapping component includes a plurality of copper bars for supplying power to each tapping control switch. One end of each copper bar is provided with a parallel connection component. The parallel connection component includes a conductive clamping plate arranged outside the corresponding copper bar. A conductive sheet is inserted between the upper and lower adjacent conductive clamping plates for realizing the parallel connection of the tapping component.

[0007] Preferably, the tapping component further includes a fixing seat arranged on the bracket. The fixing seat is detachably connected to the corresponding copper bar. A plurality of insulating support members are arranged between the adjacent two copper bars.

[0008] Preferably, the parallel connection component further includes a docking seat arranged on the bracket. The docking seat includes a connection seat with a plurality of sliding grooves. A plurality of limiting plates are arranged at the upper end of the connection seat. A plurality of the conductive clamping plates are respectively arranged in the corresponding sliding grooves.

[0009] Preferably, the conductive clamping plate includes a U-shaped copper plate disposed in the chute, a connecting plate is arranged at the upper end of the U-shaped copper plate, and the conductive sheet is detachably arranged at the upper end of the connecting plate.

[0010] Preferably, a main switch is arranged on the uppermost guide rail plate, and the main switch is electrically connected to the corresponding conductive clamping plate.

[0011] In summary, the present application includes the following beneficial technical effects:

[0012] By the combined use of the tapping component and the parallel connection component, the conductive clamping plate is used to fit on the surfaces of the copper busbar and the conductive sheet to achieve plug-in conduction. Only by fixing the docking seat and the fixed seat can the parallel connection of the tapping component be completed. Modular layout can be carried out according to the load use or other conditions, which is convenient for post-expansion. By using the parallel axis on the side of the conductive sheet, only the copper busbar and the tapping control switch are connected on the front, making the overall layout more concise and convenient for maintenance; compared with the prior art, it has the effects of convenient maintenance and convenient expansion.
