Abstract
The utility model is related to a kind of wiring pins and coil rack assembling structure, including wiring pin and coil rack, lower face inside the fixation slot of the coil rack is equipped with groove, the wiring pin is equipped with the clamping block with the fit depressions, the wiring pin is packed by being interference fitted in the fixation slot of coil rack, and the clamping block is caught in the groove of coil rack.Compared with prior art, the plastics bits that the utility model is squeezed in hole in assembling process are sealed, and will not be dropped out between dynamic and static iron core, avoid causing iron core noise or movement clamping stagnation；There is no concern that during elastic conjunction scraper and further increase the matching allowance of wiring pin and coil rack, can fix wiring pin more reliable, prevent in coiling or wiring pin is deviate from during wiring circle power cord, break enameled wire, cause contactor that cannot work.
Description
Technical field
The utility model is related to contactor technical fields, and in particular to a kind of wiring pin and coil rack assembling structure.
Background technology
After current winding wiring foot and coil rack are by elastic conjunction, link is blocked by boss and location hole
Foot, there are following defects：(1) unit of plastic fallen is squeezed in assembling process to drop out above hole, these squeeze the unit of plastic fallen, by
There is certain toughness without dropping at once in plastics, and dropping after being packed into product due to contactor is attracted the vibrations of release,
And then cause iron core noise or movement clamping stagnation or even cause coil burnout or the more serious failures such as contact is burnt；(2) at the same by
In the plastics for worrying to squeeze to fall in assembling process, the interference volume of wiring pin and skeleton cannot be too big, and smaller interference volume cannot be protected
Demonstrate,prove the fixed firmness of wiring pin, thus often occur in winding process or firmly wiring circle power cord when, wiring pin is from fixation
Deviate from slot, cause coil breakage, contactor cannot be attracted.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of wiring pin and tied with coil rack assembling
Structure.
The purpose of this utility model is achieved through the following technical solutions：
A kind of wiring pin and coil rack assembling structure, including wiring pin and coil rack, the fixation of the coil rack
Lower face inside slot is equipped with groove, and the wiring pin is equipped with the clamping block with the fit depressions, and the wiring pin leads to
Interference fit is packed into the fixation slot of coil rack, and the clamping block is caught in the groove of coil rack.This technology side
In case, the lower face that coil rack fixes slot sets groove, so is squeezed the bits of the plastics in hole and is sealed in hole, because
Wiring pin and coil rack elastic conjunction and squeezing the unit of plastic fallen or plastics bits will not drop out, avoid causing iron core noise or fortune
Dynamic clamping stagnation.
Further, the groove is blind hole, after coordinating with wiring pin, is squeezed the bits of the plastics in hole and is sealed in
In hole.
Further, the depth of the groove is 2-3mm.
Further, the clamping block is the positioning convex platform arranged on wiring pin lower surface, and the protrusion of the positioning convex platform is high
Degree is less than the depth of groove.
Further, the clamping block be arranged on wiring pin side ligule feature, the ligule feature wiring pin with
Coil rack is folded into after assembling in groove, and this match ratio boss is more secured, and the house specific size of shape feature is according to actual need
It is set, the ligule is characterized as any shape, can be square or trapezoidal, be obtained by the way that wiring pin is cut out gap
It arrives.
Further, the fixation slot of the coil rack is square that other shapes in addition can also be set as needed.
Compared with prior art, the utility model has the advantage of：
1st, in assembling process, it is squeezed the bits of the plastics in hole and is sealed, will not be dropped out between dynamic and static iron core,
It avoids causing iron core noise or movement clamping stagnation；
2nd, do not have to concern scraper during elastic conjunction and further increase the matching allowance of wiring pin and coil rack, make to connect
Stitch is fixed more reliable, prevents in coiling or wiring pin is deviate from during wiring circle power cord, break enameled wire, cause contactor not
It can work.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
A kind of wiring pin and coil rack assembling structure, as shown in Figure 3,4, including wiring pin 2 and coil rack 1, coil
Lower face inside the fixation slot of skeleton 1 is equipped with groove 3, and wiring pin 2 is equipped with the clamping block with fit depressions, and clamping block is
Positioning convex platform 4 arranged on wiring pin lower face, as shown in figure 5, wiring pin 2 is packed into the fixation of coil rack 1 by being interference fitted
In slot, positioning convex platform 4 is caught in the groove 3 of coil rack.Groove 3 can be blind hole, depth 2-3mm, positioning convex platform 4
Protrusion height is less than the depth of groove 3.
Embodiment 2
As different from Example 1, clamping block is the ligule feature 5 arranged on 2 side of wiring pin to the present embodiment, such as Fig. 6 institutes
Show, ligule feature 5 is folded into after wiring pin 2 and coil rack 1 assemble in groove 3, more secured, the She Zhuante of this cooperation
It levies 5 specific sizes to be set according to actual needs, can be square or trapezoidal, be obtained by the way that wiring pin 2 is cut out gap.
Fig. 1,2 are existing wiring pin and the structure diagram of coil rack, in contrast, the utility model coil rack is consolidated
The lower face for determining slot sets groove 3, so is squeezed the bits of the plastics in hole and is sealed in hole, because of wiring pin and coil bone
Frame elastic conjunction and squeezing the unit of plastic fallen or plastics bits would not drop out, avoid causing iron core noise or movement clamping stagnation, it is not necessary to
Worry scraper during elastic conjunction and further increase the matching allowance of wiring pin and coil rack, wiring pin fixation is made more may be used
It leans on, prevents in coiling or wiring pin is deviate from during wiring circle power cord, break enameled wire, cause contactor that cannot work.
