Abstract

The utility model relates to a wiring board for a low-voltage large-power motor. The wiring board is characterized by comprising a strip-shaped board body, wherein multiple binding posts are arranged on the elongated board body in parallel, an arc-shaped conductive frame is fixed on each binding post, each conductive frame is equipped with a bolt hole and a bolt, and the axial direction of the bolt hole and the bolt is vertical to that of the binding post. The bottom of the conductive frame is fixed with the binding post, and the top of the conductive frame is equipped with another bolt and another bolt hole for installing a connecting sheet. Fixation holes are respectively formed at the two ends of the elongated board body. The wiring board for the low-voltage large-power motor has the advantages that a leading-out wire of the motor can be connected to the wiring board along the leading-out direction of the leading-out wire instead of bending the leading-out wire for 90 degree, so that wiring is very convenient, and electrical safety is ensured; preparation is easy; and when the leading-out wires of the motor change, it is only required to adjust the number of the vertical bolts according to the number of the leading-out wires in preparation of the wiring board, so that wiring requirement of the motor can be met.

Description

The terminal block that low-pressure high-power motor uses

Technical field

The utility model relates to a kind of terminal block for motor, and the terminal block that especially a kind of low-pressure high-power motor uses, belongs to 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 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 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, leave potential safety hazard, and cause serious consequence.In addition, only have 6 binding posts on terminal block, when in order to reduce the ampacity of lead-out wire, 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 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 wiring needs.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and the terminal block that provides a kind of low-pressure high-power motor to use, facilitates lead-out wire wiring, and when lead-out wire sum reaches 12 (or more), also can meet wiring needs.

The technical scheme providing according to the utility model, the terminal block that a kind of low-pressure high-power motor uses, feature is: comprise the plate body that is strip, on microscler plate body, be arranged side by side a plurality of binding posts, 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.

The utility model has the advantages that: the lead-out wire of motor is on receiving terminal block time, and lead-out wire does not need 90 ° of bendings, but connect along the direction of drawing of lead-out wire, wiring is very convenient, and guarantees electrical safety; Terminal block is simple in structure, makes easily, when motor lead-out wire changes, only need, when casting terminal block, according to the quantity of the vertical bolt of the corresponding adjustment of the quantity of lead-out wire, can meet the wiring needs of motor.

Embodiment

Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.

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 utility model comprises the plate body 1 that is strip, and 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 6 use bolt tightenings of the copper sleeve on motor lead-out wire 5, on conduction rack 4, motor lead-out wire 5 can be directly 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 is also connected on the bolt at conduction rack 4 tops.

The utility model 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, when casting terminal block, according to the quantity of the vertical bolt of the corresponding adjustment of the quantity of lead-out wire, join again in addition the conduction rack of equal number.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.
