Abstract
The invention relates to a wiring board for a low-voltage and high-power motor. The wiring board of the low-voltage and high-power motor is characterized by comprising a strip-shaped board body, a plurality of wiring posts are arranged on the strip-shaped board body side by side, each wiring post is fixedly provided with an arched electric conduction frame, each electric conduction frame is provided with a bolt hole and a bolt, and the axial direction of the bolt holes and the bolts is perpendicular to the axial direction of the wiring posts. The bottom ends of the electric conduction frames are fixed to the wiring posts, and the top ends of the electric conduction frames are provided with the bolts and the bolt holes used for installation of connection sheets. The two ends of the strip-shaped board body are provided with fixing holes. The wiring board of the low-voltage and high-power motor has the advantages that when being connected to the wiring board, outgoing lines of the motor do not need to be bent by 90 degrees but being connected in the outgoing direction of the outgoing lines, wiring is convenient, and electrical safety is ensured; the wiring board is simple in structure and easy to manufacture; when the outgoing lines of the motor change, the wiring demand of the motor can be met just by adjusting the number of the perpendicular bolts correspondingly according to the number of the outgoing lines when the wiring board is cast.
Description
Technical field
The present invention relates to a kind of terminal block for motor, the terminal block that especially a kind of low-pressure high-power motor uses, belong to the motor manufacturing technology field.
Background technology
The terminal block of Y2 series three-phase asynchronous motor is all at plastic plate casting 6 binding posts vertical with plastic plate (as shown in Figure 1 and Figure 2).As shown in Figure 3, Figure 4, when the lead-out wire 1a of motor receives on terminal block 3a by copper sleeve 2a, 90 ° of the necessary bendings of lead-out wire 1a, the copper sleeve 2a on lead-out wire 1a just can be enclosed within on binding post 4a.Because cost is low, now increasing client is inclined to and selects the low-pressure high-power motor.The line current of low-pressure high-power motor is very large, must select thicker lead-out wire.And when the low-pressure high-power motor is selected thicker lead-out wire, lead-out wire is difficult to 90 ° of bendings in a narrow space, if bending by force, easily make copper sleeve distortion or loosening on lead-out wire, also be easy to destroy the insulating barrier of lead-out wire, stay potential safety hazard, and cause serious consequence.In addition, only have 6 binding posts on terminal block, when the ampacity in order to reduce lead-out wire and every phase two ends connect respectively 2 (or more) lead-out wires, altogether during 12 (or more) lead-out wires, 6 binding posts just can not meet the wiring needs.So, in the time of must trying every possible means to make lead-out wire on receiving terminal block wiring simple and convenient, and, when every phase two ends connect respectively 2 (or more) lead-out wires, binding post also can meet the wiring needs.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the terminal block that provides a kind of low-pressure high-power motor to use, facilitate the lead-out wire wiring, and, when the lead-out wire sum reaches 12 (or more), also can meet the wiring needs.
According to technical scheme provided by the invention, the terminal block that a kind of low-pressure high-power motor uses, feature is: comprise the plate body that is strip, be arranged side by side a plurality of binding posts on microscler plate body, fixing arch conduction rack respectively on binding post, bolt hole and bolt are set on conduction rack, this bolt hole and bolt axially and binding post axial vertical.
Bottom and the binding post of described conduction rack are fixed, and the top of conduction rack is provided for installing bolt and the bolt hole of brace.
Two ends at described microscler plate body arrange fixing hole.
Advantage of the present invention is: the lead-out wire of motor is on receiving terminal block the time, and lead-out wire does not need 90 ° of bendings, but connects along the direction of drawing of lead-out wire, and wiring is very convenient, and guarantees electrical safety; Terminal block is simple in structure, makes easily, and when motor lead-out wire changes, only need be when casting terminal block, according to the quantity of the vertical bolt of the corresponding adjustment of quantity of lead-out wire, can meet the wiring needs of motor.

Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 5～Fig. 8: as described in the terminal block that uses of low-pressure high-power motor comprise microscler plate body 1, fixing hole 2, binding post 3, conduction rack 4 etc.
As shown in Figure 5, Figure 6, the present invention includes the plate body 1 that is strip, the two ends of microscler plate body 1 are fixing hole 2, for fixing microscler plate body 1; The quantity that is arranged side by side six binding post 3(binding posts 3 on described microscler plate body 1 can be determined according to the quantity of lead-out wire), fixing arch conduction rack 4 respectively on binding post 3, bolt hole and bolt are set on conduction rack 4, this bolt hole and bolt axially and binding post 3 axial vertical;
As shown in Figure 8, the bottom of described conduction rack 4 and binding post 3 are fixing, and the top of conduction rack 4 is provided for installing bolt and the bolt hole of brace 7.
As shown in Figure 7, Figure 8, in use, terminal block is arranged on motor, every motor needs 2; By the copper sleeve 6 use bolt tightenings on motor lead-out wire 5, on conduction rack 4, motor lead-out wire 5 can be directly be connected on conduction rack 4 along the direction of drawing of lead-out wire 5, does not need to carry out 90-degree bent, and wiring is very simple and convenient, may guarantee electrical safety; Brace 7 is installed on the bolt at conduction rack 4 tops, and power line also is connected on the bolt at conduction rack 4 tops.
The present invention is simple in structure, makes easily, and easy-to-connect, safe and reliable; The style of terminal box does not need to change yet.If lead-out wire is less than 12 or during more than 12, only need be when the casting terminal block, according to the quantity of the vertical bolt of the corresponding adjustment of quantity of lead-out wire, the conduction rack of joining again in addition equal number gets final product.Such as, lead-out wire is 6, just casts 3 vertical bolts on every terminal block, joins 6 conduction racks; Lead-out wire is 18, just casts 9 vertical bolts on every terminal block, joins 18 conduction racks, by that analogy.
