Description
Technical field
The utility model belongs to the technical field of low-voltage distribution apparatus, is specifically related to a kind of low-voltage distribution apparatus lead tap structure.
Background technology
Low-voltage distribution apparatus is that switchgear is used in motor control center, power center (PC), is widely used in power plant, transformer station and heavy construction, high-rise building, airport, hospital, industrial and mining enterprises etc. receive electricity, feed, illumination, Motor Control and power factor compensation as three-phase alternating current 50Hz, voltage 380V or 660V electric power system usefulness.Low-voltage distribution apparatus integrates control, measures, protects, monitors, and internal connecting wire is a lot, and some leads need be connected with main bus bar to obtain power supply; Also have some leads to be connected with earth bus to obtain ground connection in addition; Traditional connected mode is directly on main bus bar or earth bus, to hole, and wire head dress round wire ear is connected with main bus bar or earth bus through bolt then; The workload at this kind connected mode scene is big; It is extremely inconvenient to operate, and because will on bus, hole, can influence the current capacity of bus.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of low-voltage distribution apparatus lead tap structure is provided, and its attended operation is convenient, and can not influence the current capacity of bus.
Its purpose can realize by following scheme: this low-voltage distribution apparatus lead tap structure comprises bus and lead; Overlap joint before and after the said bus is provided with the overlap joint hole at the bus overlapping part, and fastening bolt is aimed at and is equipped with in the overlap joint hole that adjacent two buses are corresponding; The fastening bolt end has been screwed nut; Its main feature is, is fixedly connected with tap at the bus overlapping part, and line trap is installed on tap; Said tap comprises substrate and socket sheet, and substrate and socket sheet are integrally formed, and substrate offers installing hole, and the socket sheet is provided with location hole; Said fastening bolt passes the installing hole of substrate, and substrate is clamped between the nut of bus and fastening bolt; Said line trap is provided with main clip slot and lead fixed groove, and main clip slot bottom land is provided with locating convex block, and the link of said lead is fixed and is clamped in the lead fixed groove; The main clip slot of said line trap is plugged on socket sheet outside, and the locating convex block of main clip slot bottom land is clamped in the location hole of socket sheet.
Be preferably, substrate edge is provided with L shaped seam, staggers downwards and form stop edge in the position of this L shaped seam semi-surrounding.
The utlity model has following advantage and effect:
1, the utility model can be clamped in lead fixed in the lead fixed groove of line trap in advance, and in advance tap is installed in the fastening bolt that is used to overlap bus; When bus and lead need connection; Only need the main clip slot of line trap is plugged on socket sheet outside; The locating convex block of main clip slot bottom land is clamped in the location hole of socket sheet and gets final product; Thereby make lead on main bus bar, obtain power supply, perhaps make lead on earth bus, obtain the connection of reliable ground connection, attended operation is got up convenient and swift.
2, the utility model utilizes overlap joint hole that bus is connected with bus as the leading point; And need on bus, not hole in addition; Do not influence the bus current capacity: though the overlap joint hole of overlapping part can make the cross-sectional area of that corresponding bus reduce, have two buses overlapping at overlapping part, the cross-sectional area of overlapping part approaches the twice at other non-overlapping position; Even therefore overlapping part offers the overlap joint hole; The cross-sectional area of this overlapping part is still big than other position, therefore says that the utility model lead tap structure does not influence the bus current capacity.
3, because there is a plurality of overlap joints hole in an overlapping part, therefore can draw multiple conducting wires.
