Abstract

The utility model relates to a positioning connecting structure that is arranged between a contactor pedestal and a coil skeleton inside the contactor. According to the technical scheme, the positioning structure is characterized in that one group of positioning concave corners or positioning convex corners in a diagonal symmetrical mode is at least arranged at the inner side surface of the contactor pedestal; positioning convex corners or positioning concave corners are arranged at one side surface of the coil skeleton, wherein the positioning convex corners or positioning concave corners and the positioning concave corners or positioning convex corners at the inner side surface of the contactor pedestal form a plugging positioning cooperation mode; and the two adjacent sides surfaces of each positioning concave corner and two adjacent side surfaced of each positioning convex corner form an inclined-surface complementary cooperation mode. On the basis of the scheme, with the novel positioning structure, the coil skeleton centering can be realized beneficially, thereby solving a problem of inaccurate positioning caused by an assembling gap; and because of the inclined surfaces of the two parts, great convenience is brought for the part die demoulding and product assembling.

Description

A kind of contactor coil frame location structure

Technical field

The utility model relate to a kind of contactor inside about the positioning connection structure between Foundation Plate of Contactor and coil rack.

Background technology

Known product coil skeleton on perpendicular to the iron core direction of motion, is located by position limiting structure, and its location structure, in order to guarantee that coil rack can be convenient for assembly in Foundation Plate of Contactor, all leaves gap.The situation that should consider extreme position in practical set, coil rack can be amesiality.The consideration of comprehensive product dimensional tolerance, design attitude can be partial in the practical set position of skeleton.This position is offset except impacting product appearance, causes assembling dislocation or gapped, more easily enters outside dust, also can affect to magnetic system.For lower core, by the spacing contactor of base, the skew of coil rack, can make the position of E type electromagnet interpole identity distance off-line circle have deviation.First spacing to coil rack for lower core, then base is spacing to coil rack, thereby realizes the fixing contactor of lower core, the deviations of coil rack, can cause the skew of lower core position, long-pending can the dwindling than design load of active polar surface of upper and lower iron core.

Summary of the invention

The utility model overcomes the problem that prior art exists, provide a kind of when coil rack is assembled in base, can fit mutually in inclined-plane on two parts, be conducive to coil rack placed in the middle, reduced because assemble the location inaccuracy problem of learning on the job and bringing, and the upper inclined-plane of two parts is to the novel contactor coil frame location structure of the component die demoulding and offering convenience property of Product Assembly.

Realize above-mentioned purpose, the utility model adopts following technology: a kind of contactor coil frame location structure, include Foundation Plate of Contactor and coil rack, it is characterized in that: on the medial surface of described Foundation Plate of Contactor, be at least provided with a composition diagonal angle symmetrically arranged location re-entrant angle or location salient angle, on described coil rack one side, be provided with and locate re-entrant angle or location salient angle and can form peg graft the location salient angle that coordinates of location or location re-entrant angle, two the adjacent sides on the re-entrant angle of described location all form inclined-plane complementary fit with two adjacent side of locating in salient angle.

By adopting such scheme, when Foundation Plate of Contactor and coil rack are seated, corresponding location re-entrant angle and locate salient angle and be mutually plugged in together.By both inclined-plane complementations, coil rack assembles from top to bottom simultaneously, can be put into easily spacing on.So just, can not stay fit-up gap, realize the precise positioning of coil rack, be conducive to the Design and manufacture that becomes more meticulous of contactor.

Further setting of the present utility model is: on the medial surface of described Foundation Plate of Contactor, be provided with two symmetrically arranged location, composition diagonal angle re-entrant angles, the adjacent two sides of each location re-entrant angle are obliquely installed, form location re-entrant angle upper end open and be greater than lower ending opening, on described coil rack, be provided with and the location salient angle of locating re-entrant angle and coordinating, the adjacent two sides of location salient angle are obliquely installed, form location salient angle upper end cross section and be less than lower end cross section, location salient angle is inserted into the close-fitting that forms tentaculum base and coil rack after the re-entrant angle of location; The shape of described each location re-entrant angle is identical with size, and location re-entrant angle is comprised of the lug being arranged on Foundation Plate of Contactor medial surface, between the lug of the location re-entrant angle of the same side, is connected, and the shape of described each location salient angle is identical with size.

By adopting such scheme, be to further optimization of the present utility model, wherein take into full account the simplicity that product is manufactured, the convenience of assembling, is connected between the lug of the location re-entrant angle of the same side in addition and can increases like this firmness of location re-entrant angle.

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

Embodiment

As shown in Fig. 1-Fig. 4, a kind of contactor coil frame location structure, include Foundation Plate of Contactor 1 and coil rack 2, on the medial surface of described Foundation Plate of Contactor 1, be at least provided with symmetrically arranged location, a composition diagonal angle re-entrant angle 11, on described coil rack 2 one sides, be provided with and locate re-entrant angle and can form the location salient angle 21 that coordinates of location of pegging graft, two adjacent sides 111 on described location re-entrant angle 11 all form inclined-plane complementary fit with two adjacent side 211 in the salient angle 21 of location, certainly we also can be location re-entrant angle 11 and location salient angle 21 transpositions in the present embodiment, by adopting such scheme, when Foundation Plate of Contactor 1 and coil rack 2 are seated, corresponding location re-entrant angle 11 and location salient angle 21 are plugged in together mutually.By both inclined-plane complementations, coil rack 2 assembles from top to bottom simultaneously, can be put into easily spacing on.So just, can not stay fit-up gap, realize the precise positioning of coil rack 2, be conducive to the Design and manufacture that becomes more meticulous of contactor.
