Description
Technical field
The utility model relates to a kind of components and parts that are used for electrical load control, particularly a kind of A.C. contactor with replaceable base.
Background technology
A.C. contactor is mainly used in the important power control member of control alternating current machine start-stop and other electrical load break-make, the basic principle of existing A.C. contactor is: comprise pedestal, top cover, base plate, relative E shape armature of direction and E shape yoke are installed in pedestal, be provided with reaction spring between E shape armature and the E shape yoke, be fixedly connected with contact supporting on the E shape armature, be elasticly connected with bridge shape moving contact on the contact supporting, pedestal is provided with and the corresponding a pair of fixed contact of bridge shape moving contact, and fixed contact links to each other with external connection end, is arranged with coil on the projection in the middle of E shape yoke, coil links to each other with control end, during use, external connection end inserts motor circuit, control end access control circuit, when coil electricity, E shape armature and E shape yoke be adhesive mutually under magneticaction, and bridge-shaped contact is communicated with a pair of fixed contact, constitutes path, make electric motor starting, on the contrary, coil blackout is under the effect of reaction spring, bridge-shaped contact and fixed contact separate, and the motor outage stops.According to different needs, A.C. contactor can be provided with one to three bridge shape moving contact and corresponding three pairs of fixed contacts, for use in load motor or three phase alternating current motor and other electrical load.In order to adapt to different installation occasions, its base plate need adopt metal base plate or plastic bottom board.
Mainly there is following shortcoming in existing A.C. contactor:
At first, the base plate of same A.C. contactor only can be selected a kind of of plastic bottom board and metal base plate, and different base plate A.C. contactors have different structures, be applicable to different installation occasions, thereby under different occasions, need to select for use different A.C. contactors, the inconvenience that this just causes and the raising of cost.
Secondly, because E shape yoke does not have buffer structure, when E shape yoke and the mutual adhesive of E shape armature, meeting produces collision and vibrates, thereby can drive contact vibration and produce the contact secondary rebound starting the arc, causing the product loss of function, the employing rubber parts that has is as buffer unit, yet General Purpose Rubber spare wears out easily and follows the string, thereby loses the function of buffering vibration;
The 3rd, connect by screw usually between the top cover of existing A.C. contactor and the pedestal, thereby cause the inconvenience of assembling when producing;
The 4th, the top, protruding end of the E shape yoke both sides of existing A.C. contactor is arranged with short-circuited conducting sleeve usually, to eliminate unnecessary noise, because E shape yoke and E shape armature bump when adhesive, and cause this short-circuited conducting sleeve to be subjected to vibratory impulse regularly, on four angles of this short-circuited conducting sleeve, be prone to fracture, make it send huge noise, even lose due function.
The utility model content
The utility model provides a kind of A.C. contactor with replaceable base, its main purpose is to overcome the base plate of same A.C. contactor in the prior art only can select a kind of of plastic bottom board and metal base plate, thereby can not be applicable to the different defectives that occasion is installed simultaneously.
Two of the purpose of this utility model is to overcome existing A.C. contactor owing to adopt rubber parts as the parts that reduce to vibrate, thereby easily aging and lose vibration-damping function and be directed at the defective that A.C. contactor damages.
Three of the purpose of this utility model is to overcome between existing A.C. contactor pedestal and a lid, the base plate owing to adopt screw to be connected and fixed, thereby the defective that comparatively bothers of assembling process.
Four of the purpose of this utility model is to overcome the defective of the short-circuited conducting sleeve of existing A.C. contactor at four corner easy fractures.
In order to achieve the above object, the utility model adopts following technical scheme: comprise top cover, pedestal, base, top cover is located at pedestal top, base is located at the pedestal bottom, base is formed by fixedly connecting by plastic frame body and metal base plate, the metal base plate edge is provided with some installing holes, also comprise E shape armature and E shape yoke that direction is relative, E shape yoke back relies on the metal base plate by insulating trip, in the middle of E shape yoke, be arranged with the coil support frame on the projection, two ends protuberance end face is arranged with short-circuited conducting sleeve, be arranged with coil on the coil support frame, the two ends of coil are provided with the control end that convexedly stretches in the pedestal outside, be provided with reaction spring between coil support frame and the E shape armature, be fixedly connected with contact supporting on the E shape armature, be elasticly connected with one to three bridge shape moving contact on the contact supporting, be installed with bridge shape moving contact corresponding a pair of on the pedestal to three pairs of fixed contacts, the pedestal outside is provided be connected with fixed contact a pair of to three pairs of external connection end, also comprise a self-existent integrally formed plastics replacement base in addition, the shape all around that these plastics are replaced base is identical with the shape of plastic frame body, its both sides, bottom surface extroversion extends to form mount pad, the mount pad top edge is provided with some installing holes, and the mount pad bottom is provided with mounting groove.
Bottom, described pedestal two side is provided with the L shaped pin of downward extension, relevant position, middle part, plastic frame body two side is provided with the connecting portion that outwards protrudes out, the metal base plate dual-side is provided with the upwardly extending L shaped pin that falls, pedestal, plastic frame body and the metal base plate connecting portion by this L shaped pin, plastic frame body with fall L shaped pin and fixedly connected, plastics replace the base bilateral wall medium position also corresponding be provided with can with the suitable connecting portion of the L shaped pin of pedestal.
The contact-making surface of coil support frame and E shape yoke is provided with the projection of some " " shapes or " Off type ", the contact-making surface part hollow out of base plate and E shape yoke forms an elastic construction that slightly raises up, and plastics are replaced the also corresponding elastic construction that slightly raises up that is provided with in bottom of base.
Described top cover edge is provided with the hook-shaped snap close piece of some downward extensions, and the pedestal sidewall is provided with the catching groove that matches with this hook-shaped snap close piece near the place, top.
The sectional area in short-circuited conducting sleeve four bights is greater than the sectional area of other parts.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: at first, the utility model can be replaced between metal base plate and plastics replacement base, to satisfy the installation needs of different occasions, and needn't adopt the A.C. contactor of different structure, thereby improved the standardization of producing; Secondly, the utility model is by " " shape on the contact-making surface of coil support frame and E shape yoke or " Off type " projection and metal base plate or replace elastic construction that the contact-making surface part hollow out of base bottom and E shape yoke forms and cooperate and carry out vibration reduction and cushioning, adopt than in the past rubber parts as damping means more reliably with durable; The 3rd, adopt the snapping mode to connect between the utility model top cover and the pedestal, assemble simple and convenient; The 4th, short-circuited conducting sleeve of the present utility model is owing to have reinforcement in four corners, thereby than in the past short-circuited conducting sleeve easy fracture more not; The 5th, the utility model is the full-closed structure structure substantially, has better seal than in the past product, more is not subject to the influence of impurity such as extraneous dust.
