Abstract

The utility model discloses a motor coil framework. The upper end of the coil framework is provide with a convex column; the convex column is provide with a binding post mounting hole; and the sum of the depth of the binding post mounting hole and the length of the binding post exposed outside the upper end surface of the convex column after the binding post is assembled is greater than the length of the binding post. According to the utility model, because the sum of the depth of the binding post mounting hole and the length of the binding post exposed outside the upper end surface of the convex column after the binding post is assembled is greater than the length of the binding post, namely, a certain space is set aside below the binding post on the coil framework, and after the binding post completes the winding and tin plating, the enameled wire is fixed and is tightly tensioned; a downward pressing force is then applied to the binding post, so that the end of the binding post enters the reserved space; and correspondingly, the end part of the combination part of the enameled wire and a wrapping post retreats upward as shown in the picture, so that the enameled wire is loosened to avoid the disconnection problem of the wire.

Description

A kind of motor coil skeleton

Technical field

The utility model relates to a kind of coil rack of motor.

Background technology

Existing motor coil binding post is through winding the line and warding off after tin processing, enamelled wire may stretch tight tightlyer, then binding post is directly fixed on electrode coil skeleton, on coil rack, do not have to arrange and can supply the lax device of enamelled wire, in installation process below, may break, affect product quality.

Utility model content

The purpose of this utility model is to provide a kind of motor coil skeleton of generation of the problem of avoiding again breaking simple in structure.

The technical scheme that realizes the utility model object is a kind of motor coil skeleton, and the upper end of coil rack arranges projection; Binding post installing hole is set on described projection; The length sum that the rear binding post of the degree of depth of described binding post installing hole and assembling exposes projection upper surface is greater than the length of binding post.

The degree of depth of described binding post installing hole is 2-5mm with the range difference that the rear binding post of assembling exposes the length sum of projection upper surface and the length of binding post.

Adopted technique scheme, the utlity model has following beneficial effect: the length sum that (1) the utility model exposes projection upper surface due to binding post after the degree of depth of binding post installing hole and assembling is greater than the length of binding post, also the binding post on coil rack below reserved certain space, binding post completes coiling and wards off after tin, enamelled wire is fixing, and stretch tight tightlyer, now pairs of posts applies one and presses downward to power again, make binding post end enter headspace, the end that correspondingly enamelled wire is combined with wrapping post retreats to top shown in figure, enamelled wire is relaxed, avoided the generation of broken string problem.

(2) the utility model is by the range difference of the two, namely for moving down, binding post allows enamelled wire be able to lax distance to be controlled within the scope of 2-5mm, be enamelled wire and given enough slack space, can not make again the too high assembling that affects other accessories of projection, assembling is also very convenient simultaneously.

Accompanying drawing explanation

For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below

Fig. 1 is structural representation of the present utility model, demonstration be that binding post is put into the schematic diagram that binding post installing hole does not also press down.

Fig. 2 is the A place enlarged drawing of Fig. 1.

Fig. 3 is structural representation of the present utility model, demonstration be that binding post is put into binding post installing hole and pressed down the schematic diagram being seated.

Fig. 4 is the B place enlarged drawing of Fig. 3.

Attached number in the figure is:

Coil rack 1, projection 2, binding post installing hole 3, binding post 4, enamelled wire 5.

Embodiment

(embodiment 1)

See Fig. 1 to Fig. 4, a kind of motor coil skeleton of the present embodiment, the upper end of coil rack 1 arranges projection 2; On described projection 2, binding post installing hole 3 is set; The length sum that the rear binding post 4 of the degree of depth of described binding post installing hole 3 and assembling exposes projection 2 upper surfaces is greater than the length of binding post 4.The degree of depth of described binding post installing hole 3 is 2-5mm with the range difference that the rear binding post 4 of assembling exposes the length sum of projection 2 upper surfaces and the length of binding post 4.

As depicted in figs. 1 and 2, the length sum of exposing projection 2 upper surfaces due to binding post 4 after the degree of depth of binding post installing hole 3 and assembling is greater than the length of binding post 4, also the binding post on coil rack 14 below reserved certain space, binding post 4 completes coiling and wards off after tin, enamelled wire 5 is fixing, and stretch tight tightlyer, now pairs of posts 4 applies one and presses downward to power again, make binding post end enter headspace, as shown in Figure 3 and Figure 4, correspondingly enamelled wire 5 retreats to top shown in figure with the end of wrapping post 4 combinations, enamelled wire 5 is relaxed, avoided the generation of broken string problem.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.

Claims

1. a motor coil skeleton, is characterized in that: the upper end of coil rack (1) arranges projection (2); Binding post installing hole (3) is set on described projection (2); The length sum that the rear binding post (4) of the degree of depth of described binding post installing hole (3) and assembling exposes projection (2) upper surface is greater than the length of binding post (4).

2. a kind of motor coil skeleton according to claim 1, is characterized in that: the degree of depth of described binding post installing hole (3) is 2-5mm with the range difference that the rear binding post (4) of assembling exposes the length sum of projection (2) upper surface and the length of binding post (4).
