Description

A kind of anti-loose structure of contactor

Technical field

The utility model relates to a kind of anti-loose structure of contactor.

Background technology

For realizing automation assembling, conventionally on contactor coil frame, form containing cavity, in described containing cavity side mouth, conductive metal sheet is arranged in containing cavity, is connected with coil electric, and screw is placed in containing cavity by side mouth, in containing cavity, form the position-limit mechanism of restriction toner screw, this position-limit mechanism can be elastic sheet, and through hole is formed on containing cavity top, and described through hole is used for locking screw; Containing cavity front side wall forms fluting, and conductive metal sheet is exposed, and while making to detect, probe can directly contact and detect with electric metal plate.

In the time of assembling, first will after conductive metal sheet kinking, pack in coil rack, then by manipulator, screw is packed into containing cavity from containing cavity side mouth, now, the position-limit mechanism restriction toner screw in containing cavity; Finally by screw lock on conductive metal sheet, realize automation assembling.

Due in containing cavity side mouth, form fluting at containing cavity front side wall, simultaneously, form through hole at containing cavity top, the bulk strength that makes containing cavity a little less than, and then it is easily loosening to make to be installed on binding post conductive metal sheet in containing cavity, cause loose contact, or produce electric arc.

Utility model content

The purpose of this utility model is to provide a kind of anti-loose structure of contactor, loosening effectively to prevent that binding post conductive metal sheet from occurring.

For reaching above-mentioned purpose, solution of the present utility model is:

An anti-loose structure for contactor, comprises the body, coil rack and base; Coil rack is arranged in the body, forms the containing cavity of side mouth on coil rack; On base, form the first clamp and the second clamp, the body is arranged on base, and containing cavity snaps between the first clamp and the second clamp, and the first clamp snaps in side mouth, the first clamp and the second clamp clamping containing cavity; On the sidewall of side mouth, form draw-in groove, on the first clamp, form fixture block, fixture block snaps in draw-in groove; At containing cavity front side wall, groove is set, on the base between the first clamp and the second clamp, projection is set, described projection snaps in described groove.

Further, form the first block on the body, accordingly, form the second block on the first clamp, the body is arranged on base, and the body the first block is resisted against on the first clamp, and first clamp the second block is resisted against on the body.

Further, described groove is set to T-shape groove, and accordingly, described projection is set to T-shape projection.

Further, on the first clamp, trip is set, accordingly, at containing cavity top, hole clipping is set, trip inserts in hole clipping.

Adopt after such scheme, the utility model forms the first clamp and the second clamp on base, and containing cavity snaps between the first clamp and the second clamp; Meanwhile, on the sidewall of side mouth, form draw-in groove, on the first clamp, form fixture block, fixture block snaps in draw-in groove.The first clamp and the second clamp clamping containing cavity, prevent the loosening distortion of containing cavity, and meanwhile, fixture block coordinates further with draw-in groove, prevents the loosening distortion of containing cavity, thereby the binding post conductive metal sheet that effectively prevents from being installed in containing cavity occurs loosening.

Meanwhile, the body the first block is resisted against on the first clamp, and first clamp the second block is resisted against on the body, further prevents the loosening distortion of containing cavity sidepiece.

At containing cavity front side wall, groove is set, on the coil rack between the first clamp and the second clamp, projection is set, described projection snaps in described groove, effectively prevents the anterior loosening distortion of containing cavity.

In the first clamp upper end, trip is set, at containing cavity top, hole clipping is set, trip inserts in hole clipping, strengthens the first clamp intensity, further effectively prevents the loosening distortion of containing cavity sidepiece.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.

Consult shown in Fig. 1 to Fig. 6, the anti-loose structure of a kind of contactor that the utility model discloses, comprises the body 1, coil rack 2 and base 3.

Coil rack 2 is arranged in the body 1, forms containing cavity 21 on coil rack 2, and containing cavity 21 sidepieces arrange opening 211.

On base 3, form the first clamp 31 and the second clamp 32, the body 1 is arranged on base 3, and containing cavity 21 snaps between the first clamp 31 and the second clamp 32, and the first clamp 31 snaps in side mouth 211, and the first clamp 31 and the second clamp 32 clamp containing cavity 21.

As shown in Figure 5, form draw-in groove 212 on the sidewall of side mouth 211, on the first clamp 31, form fixture block 311, as shown in Figure 6, fixture block 311 snaps in draw-in groove 212.

Describedly clamp from containing cavity 21 sidepieces, prevent the loosening distortion of containing cavity 21, thereby the binding post conductive metal sheet (not shown) that effectively prevents from being installed in containing cavity 21 occurs loosening.

In the present embodiment, on the body 1, form the first block 11, as shown in Figure 4, accordingly, on the first clamp 31, form the second block 312, as shown in Figure 6, the body 1 is arranged on base 3, the body 1 first block 11 is resisted against on the first clamp 31, and the first clamp 31 second blocks 312 are resisted against on the body 1, further prevents the loosening distortion of containing cavity 21 sidepieces.

For effectively preventing the anterior loosening distortion of containing cavity 21, at containing cavity 21 front side walls, groove 213 is set, as shown in Figure 5, accordingly, on the base 3 between the first clamp 31 and the second clamp 32, projection 33 is set, as shown in Figure 6, described projection 33 snaps in described groove 213.For making engaging comparatively stable, described groove 213 is set to T-shape groove, and as shown in Figure 5, accordingly, described projection 33 is set to T-shape projection, as shown in Figure 6.

For further strengthening the first clamp 31 intensity, effectively prevent the loosening distortion of containing cavity 21 sidepieces, on the first clamp 31, trip 313 is set, as shown in Figure 6, accordingly, at containing cavity 21 tops, hole clipping 214 is set, as shown in Figure 3, trip 313 inserts in hole clipping 214.

The foregoing is only preferred embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection range of this case.
