Abstract
The utility model belongs to the technical field of motor manufacturing, and relates to an electroconductive rack, in particular to an electroconductive rack for a low-voltage high-power motor. According to the technical scheme provided by the utility model, the electroconductive rack for the low-voltage high-power motor comprises an electroconductive rack body, wherein the electroconductive rack body comprises a middle connecting plate; an upper end connecting plate is arranged at the upper end of the middle connecting plate; a bottom connecting plate is arranged at the lower end of the middle connecting plate; and at least two connecting holes are formed in the middle connecting plate. According to the rack, when the power of the motor is higher, a wiring board is not required to be replaced when two outgoing lines are connected with each of the two ends of each phase for reducing the current carrying capacity of the outgoing lines, totally, twelve outgoing lines are connected, wiring utilization of the outgoing lines can be satisfied, the mounting dimension is not changed, and the rack is simple in structure, easy to manufacture, safe and reliable, and facilitates wiring.
Description
Technical field
The utility model relates to a kind of conduction rack, and the conduction rack that especially a kind of low-pressure high-power motor uses belongs to the technical field that motor is manufactured.
Background technology
At present, on the conduction rack in the terminal box of low-voltage three phase asynchronous motor, be provided with one for connecting the connecting hole of lead-out wire, and on terminal block, only have six double-screw bolts for conduction rack is installed, that is to say on terminal block and can only fill six conduction racks.When a motor lead-out wire of a conduction bridge joint, the lead-out wire of motor is at most the six roots of sensation.When the power of motor is larger, in order to reduce the ampacity of lead-out wire and every phase two ends connect respectively two altogether during 12 lead-out wires, terminal block just cannot wiring.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the conduction rack that provides a kind of low-pressure high-power motor to use, and it is simple and compact for structure, the wiring that can meet many lead-out wires is used, and wide accommodation is easy to install, cost is low, safe and reliable.
The technical scheme providing according to the utility model, the conduction rack that described low-pressure high-power motor uses, comprises conduction rack body, and described conduction rack body comprises middle connecting plate, the upper end of described middle connecting plate is provided with upper end connecting plate, and the lower end of middle connecting plate is provided with bottom connecting plate; At least two connecting holes are set on middle connecting plate.
Between described middle connecting plate and upper end connecting plate, bottom connecting plate, be arch.Described upper end connecting plate is provided with upper end connecting hole; Bottom connecting plate is provided with bottom connecting hole.
On described middle connecting plate, by connecting hole and connecting bolt, be fastenedly connected with lead-out wire.Described upper end connecting plate is installed brace by upper end connecting hole and upper end fastening bolt.Described bottom connecting plate is fixed on terminal block by bottom connecting hole and bottom fastening bolt.
Advantage of the present utility model: when the power of motor larger, in order to reduce the ampacity of lead-out wire and every phase two ends connect respectively two altogether during 12 lead-out wires, without changing terminal block, the wiring that can meet many lead-out wires is used, installation dimension also can not change, simple in structure, makes easily, easy-to-connect, safe and reliable.

Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2: in order to meet the connection request of more lead-out wire 10, the utility model comprises conduction rack body, described conduction rack body comprises middle connecting plate 3, the upper end of described middle connecting plate 3 is provided with upper end connecting plate 1, and the lower end of middle connecting plate 3 is provided with bottom connecting plate 5; At least two connecting holes 4 are set on middle connecting plate 3.
Particularly, between described middle connecting plate 3 and upper end connecting plate 1, bottom connecting plate 5, be arch.Upper end connecting plate 1, middle connecting plate 3 and bottom connecting plate 5 structure that can be formed in one, upper end connecting plate 1 is positioned at the upper end of middle connecting plate 3, and is skewed, and bottom connecting plate 5 is positioned at the lower end of middle connecting plate 3, and bottom connecting plate 5 is horizontal.Connecting hole 4 on middle connecting plate 3 is at least two, and the utility model embodiment there is shown and 4, two connecting holes 4 of two connecting holes is set for side by side on middle connecting plate 3.When more connecting hole 4 is set, can meet being connected and fixed of many lead-out wires 10.
Described upper end connecting plate 1 is provided with upper end connecting hole 2, and described upper end connecting hole 2 matches with upper end fastening bolt 7; Bottom connecting plate 5 is provided with bottom connecting hole 6, and bottom connecting hole 6 matches with bottom fastening bolt 9.
As shown in Figure 3 and Figure 4: on described middle connecting plate 3, by connecting hole 4 and connecting bolt 8, be fastenedly connected with lead-out wire 10.Described upper end connecting plate 1 is installed brace by upper end connecting hole 2 and upper end fastening bolt 7.Described bottom connecting plate 5 is fixed on terminal block by bottom connecting hole 6 and bottom fastening bolt 9.
After the lead-out wire 10 of motor is guided to terminal box, copper sleeve on two lead-out wires 10 of every phase one end is pressed in respectively on the middle connecting plate 3 of conduction rack body, then wear from inside to outside connecting bolt 8, reverse side adds plain washer, spring washer and nut screwing clamping, so that lead-out wire 10 is fastenedly connected on middle connecting plate 3.In the upper end connecting hole 2 of upper end connecting plate 1, put on end fastening bolt 7, and be with plain washer, spring washer and nut, by upper end fastening bolt 7, brace is installed, in bottom connecting hole 6 on bottom connecting plate 5, wear bottom fastening bolt 9, and add plain washer, spring washer and nut, so that whole conduction rack this locality is fixed on terminal block.
When the power of motor is larger, in order to reduce the ampacity of lead-out wire, every phase two ends connect respectively two altogether during 12 lead-out wires, and without changing terminal block, installation dimension also can not change, simple in structure, make easily, and easy-to-connect, safe and reliable.
