The embodiment providing below in conjunction with accompanying drawing 1 to 8, further illustrates the tool of contactor of the present utility modelBody embodiment. Contactor of the present utility model is not limited to the description of following examples.

As shown in Figure 1, contactor of the present utility model comprise base 1, be arranged on yoke 2 in base 1,Coil rack 3 and lug plate, yoke 2 is arranged on the base plate of base 1, and coil rack 3 is arranged on base 1In and be positioned at the top of yoke 2, lug plate is plugged on the sidewall of coil rack 3. Yoke 2 is E type, EIn type yoke 2 opening one side direction, place, the bottom surface of yoke 2 is arranged on the base plate of base 1, E type yoke 2Bottom be provided with the yoke through hole that level connects, installation sheet 21 is through yoke through hole, it is exposed at outside yokeTwo ends are coated with supporter, consult Fig. 3, are relatively set with concave shape flat between two lateral sidewalls in base 1Platform 16, is formed for installing yoke 2 and installation sheet 21 and is coated with between concave shape platform 16 and base 1The yoke mounting groove 17 of the part of gripping member, when installation, yoke 2 packs in yoke mounting groove 17, installation sheet21 parts that are coated with supporter snap in the interior formation of sunk part the consolidating yoke 2 of two concave shape platforms 16Fixed. The middle part of coil rack 3 is provided with the installing hole 36 of axial perforation, in installing hole 36 and E type yoke 2Arm matches, and coil rack 3 is displaced downwardly to and is arranged in base 1 along the middle arm of E type yoke 2 by installing hole.

Consult Fig. 2, be outside equipped with the installation panel 11 being connected with the outer wall of base 1 base plate at base 1, peaceThe mounting screw hole 111 that the middle part of dress panel 11 is provided with base 1 installs contactor, the outer wall of base 1 sidewallGo up and be provided with mechanical chain part 12 with installation panel 11 adjacents, described installation panel 11 and mechanical chain partBetween 12, reinforce the connection by being provided with reinforcement 13. Simple in structure, strengthen fastness, avoid fracture damaged,Save cost, good looking appearance.

Described reinforcement 13 is laid in the side in mounting screw hole 111 along the edge of installation panel 11; DescribedReinforcement 13 is triangle or L shaped or right angle is fan-shaped, the upper table of the base of reinforcement 13 and installation panel 11Face laminating, the sidewall laminating of its side and mechanical chain part 12. Stability Analysis of Structures, ensures the strong of reinforcement 13Degree, strengthen effect. The consistency of thickness of the panel of the thickness of reinforcement 13 and mechanical chain part 12, addsStrong muscle 13 is the integrated formed structure of integral molded plastic moulding with installation panel 11 and mechanical chain part 12. StructureFirmly evenly, be easy to processing, adopt the integrated formed structure of integral molded plastic moulding; Guarantee that stream material is smooth and easy, anti-Only distortion, the intensity of guarantee structure, avoids fracture.

The laying mode of above-mentioned reinforcement 13 can be also that described reinforcement 13 is positioned at mounting screw hole 111Top, one end is connected on the sidewall of mechanical chain part 12, the other end is connected on installation panel 11;Or, two V-shaped connections of reinforcement 13, link is connected with mechanical chain part 12, mounting screwHole 111 is in the opening of the reinforcement 13 of two V-shaped connections.

In a specific embodiment, four installation panels 11 are four jiaos and are laid in outside base 1, Mei GeanThe middle part of dress panel 11 is equipped with mounting screw hole 111, on the outer wall of base 1 sidewall and be positioned at horizontal twoBetween individual installation panel 11, be provided with four installations of 12, two mechanical chain parts of mechanical chain part 12 and both sidesBetween panel 11, reinforce the connection by being provided with four reinforcements 13, four reinforcements 13 are arranged on four installationsThe edge of panel 11.

Consult Fig. 3, in described base 1, be provided with and can fix and spacing yoke mounting groove 17 for yoke 2, magneticYoke 2 is arranged in the yoke mounting groove 17 of base 1, on the base plate of described base 1 and be positioned at yoke mounting grooveIn 17, be provided with the buffering convex closure 14 that can be subject to for absorption yoke 2 impulse force. Simple in structure, reduce extra bufferingWhen part, realize pooling feature, save part, simplify assembly process, raise the efficiency. Preferably, slowRush convex closure 14 one-body molded with base 1, base adopts nylon material, itself has certain elasticity, cushions protrudingThe structure that bag adds supporter can meet the cushioning effect between yoke and base.

The quantity of described buffering convex closure 14 is at least two, and buffering convex closure 14 intervals are laid in the end of base 1On plate, between adjacent buffering convex closure 14, be provided with buffer groove 15. By being provided with between buffering convex closure 14Buffer groove 15, in the case of not increasing the height of buffering convex closure 14 relative base 1 base plates, increases yoke2 surpluses that swing up and down while being subject to impulse force, strengthen buffering effect, ensure that impulse force absorbs the reset of rear magnetic yoke 2, carriesHigh reliability.

The base plate that described buffering convex closure 14 parallel interval are laid in base 1 transversely, buffering convex closure 14 verticalBe greater than lateral dimension to size. The lateral dimension of yoke 2 is greater than longitudinal size, is subject to for absorbing yoke 2Buffering convex closure 14 lateral separations of impulse force are distributed in the below of yoke 2, ensure horizontal and vertical cushion areaEquilibrium, disperses impact-absorbing power, strengthens buffering effect, avoids yoke 2 to rock, and improves stability. Above-mentionedThe arrangement mode of buffering convex closure 14 on base 1 base plate can be to be also diagonal angle or triangle or four jiaos to be arranged onOn the base plate of base 1, the lateral dimension of buffering convex closure 14 is greater than longitudinal size. Being used for absorbing yoke 2 is subject toThe buffering convex closure 14 of impulse force is dislocatedly distributed below yoke 2, by the impulsive force absorption of staggering, avoids yoke 2Rock and damage. Further, outermost two buffering convex closures 14 to adjacent with it base 1 sidewall itBetween distance be all less than the distances of outermost two bufferings between convex closures 14. Avoid cushioning convex closure 14 tooConcentrate on middle or a side, improve the stability of yoke 2.

The solid construction that described buffering convex closure 14 is made for elastomeric material certainly, can be also hollow-core construction.Buffering convex closure 14 be shaped as the high arc in low centre, two ends, the curved setting of buffering convex closure 14, comparesIn other shape, buffering effect is more obvious, and what make that yoke 2 contacts in buffering course is round and smooth cambered surface,Avoid rigid collision. Buffering convex closure 14 is with respect to buffer groove 15 described in the aspect ratio of the backplate surface of base 1The degree of depth with respect to the backplate surface of base 1 is large, avoids the interior buffer groove of base 1 15 places too weak, protectsThe reliability of barrier product. Certainly, the shape of buffering convex closure 14 can be also box-shaped, bucking ladder, waveShape.

As shown in Fig. 4-7, lug plate 4 is provided with installs convex closure 411, on the upper surface of described coil rack 3Be provided with and can fixing lug plate boss 31 be installed for lug plate 4, described lug plate boss 31 is vertically provided with and pacifiesThe accommodation hole 314 that matches of dress convex closure 411, on its sidewall level be provided with extend to accommodation hole 314 belows and withThe lug plate mounting groove 313 that accommodation hole 314 is connected, consults Fig. 7, and when installation, lug plate 4 is from lug plateMounting groove 313 outward flanges are pushed accommodation hole 314 belows to, finally snap in accommodation hole 314 by convex closure 411 is installedIn, be fixed on coil rack. The structure setting coordinating by vertical convex closure and hole, damage while avoiding assemblingCoil rack body produce burr, improve product reliability, assemble simple and convenient, improve efficiency of assembling, justIn realizing automation assembling.
