Description

A kind of anti-loose structure

Technical field

The present invention relates to a kind of anti-loose structure, it is be applied to the electrical equipments such as catalyst, chopper.

Background technology

For realizing Automated assembly, form containing cavity generally on coil rack, in described containing cavity side mouth, conductive Metallic plate is arranged in containing cavity, is connected with coil electric, and screw is placed in containing cavity by side mouth, is formed in containing cavity Limit the position-limit mechanism of toner screw, this position-limit mechanism can be elastic sheet, accommodating top of chamber forms through hole, described through hole is used In lock screw；Containing cavity front side wall forms fluting, and conductive metal sheet is exposed so that during detection, probe can directly and electric metal Plate contact is detected.

In assembling, first will load in coil rack after conductive metal sheet kinking, then by mechanical hand, screw is calm Put chamber side mouth and load in containing cavity, now, the position-limit mechanism in containing cavity limits toner screw；Finally screw lock is existed On conductive metal sheet, realize Automated assembly.

Due in containing cavity side mouth, forming fluting in containing cavity front side wall, meanwhile, being formed in accommodating top of chamber logical Hole is so that the bulk strength of containing cavity is weaker, and then makes the binding post conductive metal sheet being installed in containing cavity easily loose Dynamic, cause loose contact, or produce electric arc.

Content of the invention

It is an object of the invention to provide a kind of anti-loose structure, effectively to prevent binding post conductive metal sheet from pine occurring Dynamic.

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

A kind of anti-loose structure, including the body, coil rack and base；Coil rack is arranged in the body, in coil rack The upper containing cavity forming side mouth；First clamp and the second clamp are formed on base, the body is arranged on base, and houses Chamber snaps between the first clamp and the second clamp, and the first clamp snaps in side mouth, and the first clamp and the second clamp clamp Containing cavity；The side wall of side mouth forms draw-in groove, fixture block is formed on the first clamp, fixture block snaps in draw-in groove.

Further, the first block is formed on the body, accordingly, the second block is formed on the first clamp, the body is installed On base, the body first block is resisted against on the first clamp, and first clamp the second block is resisted against on the body.

Further, groove is set in containing cavity front side wall, accordingly, on the base between the first clamp and the second clamp Setting projection, described projection snaps in described groove.

Further, described groove is set to " t " type groove, and accordingly, described projection is set to " t " type projection.

Further, trip is arranged on the first clamp, accordingly, hole clipping is set in accommodating top of chamber, trip inserts hole clipping In.

After such scheme, the present invention forms the first clamp and the second clamp on base, and containing cavity snaps in the first card Between plate and the second clamp；Meanwhile, the side wall of side mouth forms draw-in groove, fixture block, fixture block card are formed on the first clamp Enter in draw-in groove.First clamp and the second clamp clamping containing cavity, prevent containing cavity from loosening deformation, meanwhile, fixture block is coordinated with draw-in groove Further, prevent containing cavity from loosening deformation, thus effectively preventing the binding post conductive metal sheet being installed in containing cavity from occurring Loosen.

Meanwhile, the body first block is resisted against on the first clamp, and first clamp the second block is resisted against on the body, enters one Step prevents containing cavity sidepiece from loosening deformation.

Groove is set in containing cavity front side wall, the coil rack between the first clamp and the second clamp arranges projection, Described projection snaps in described groove, effectively prevents anterior the loosening of containing cavity from deforming.

Trip is set in the first clamp upper end, hole clipping is set in accommodating top of chamber, in trip insertion hole clipping, strengthens the first card Plate intensity, effectively prevents containing cavity sidepiece from loosening deformation further.

Specific embodiment

Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.

Refering to shown in Fig. 1 to Fig. 6, a kind of anti-loose structure that the present invention discloses, including 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 sidepiece arranges opening 211.

Form the first clamp 31 and the second clamp 32 on the base 3, the body 1 is installed on the base 3, and containing cavity 21 snaps in Between first clamp 31 and the second clamp 32, and the first clamp 31 snaps in side mouth 211, the first clamp 31 and the second clamp 32 clamping containing cavities 21.

As shown in figure 5, forming draw-in groove 212 on the side wall of side mouth 211, the first clamp 31 forms fixture block 311, As shown in fig. 6, fixture block 311 snaps in draw-in groove 212.

Described clamped from containing cavity 21 sidepiece, prevent containing cavity 21 loosen deformation, thus effectively preventing from being installed on appearance Put the binding post conductive metal sheet (not shown) in chamber 21 to occur loosening.

In the present embodiment, the first block 11 is formed on the body 1, as shown in figure 4, accordingly, shape on the first clamp 31 Become the second block 312, as shown in fig. 6, the body 1 is installed on the base 3, the body 1 first block 11 is resisted against on the first clamp 31, And the first clamp 31 second block 312 is resisted against on the body 1, prevent containing cavity 21 sidepiece from loosening deformation further.

In order effectively to prevent, containing cavity 21 is anterior to loosen deformation, arranges groove 213 in containing cavity 21 front side wall, as shown in figure 5, Accordingly, the base 3 between the first clamp 31 and the second clamp 32 arranges projection 33, as shown in fig. 6, described projection 33 blocks Enter in described groove 213.For making engaging relatively stable, described groove 213 is set to " t " type groove, as shown in figure 5, corresponding Ground, described projection 33 is set to " t " type projection, as shown in Figure 6.

For further enhancing the first clamp 31 intensity, effectively prevent containing cavity 21 sidepiece from loosening deformation, in the first clamp 31 Upper setting trip 313, as shown in fig. 6, accordingly, arranges hole clipping 214 at containing cavity 21 top, as shown in figure 3, trip 313 is inserted Enter in hole clipping 214.

Illustrate the specific features of anti-loose structure of the present invention above, described anti-loose structure can also be answered taking catalyst as a example For in the electric equipments such as chopper, switch.

The foregoing is only presently preferred embodiments of the present invention, not the restriction to this case design, all designs according to this case are closed The equivalent variations that key is done, each fall within the protection domain of this case.
