Abstract
The utility model relates to a contactor, and particularly relates to an arc extinguishing member for a contactor. The utility model adopts the following technical scheme: the arc extinguishing member for the contactor is formed by integral bending of a metal member, and is provided with two side plates with a same shape and also provided with a transverse plate between the two side plates; the two side plates are symmetrically arranged at two sides of the transverse plate; a transition part between the two side plates and the transverse plate is respectively shaped like a right angle; the upper and lower end of the two side plates are protruded outside the transverse plate; and the middle of the transverse plate is provided with a through hole. The arc extinguishing member for the contactor is characterized in that: the two right-angle parts are respectively provided with a reinforcement point which is formed by stamping; the reinforcement point forms a depression at an outer lateral surface of the right angle; and correspondingly, a protrusion is formed at an inner lateral surface of the right angle. By adopting the above technical scheme, the problems in the prior art are overcome, and the arc extinguishing member for the contactor is simple in structure and low in production cost.
Description
Technical field
The utility model relates to the arc extinction part on a kind of contactor, particularly contactor.
Background technology
For rapid extinguish arcs, protection main contact, improves life of product, and arc extinction part generally all can be set in A.C. contactor.Under "on" position, when dynamic and static contact disengages, between two contacts, still there is voltage, in the time that this voltage exceedes a certain numerical value, make the medium between dynamic and static contact breakdown, ionize, produce thus electric arc.Be installed under the effect of arc extinction part outside contact; there is distortion in space around in the magnetic field that arc current produces; make the electromagnetic attraction producing drive arc current to flow to arc extinction part; electric arc contacts with arc extinction part and makes electric arc cooling fast, and then reaches the object of eliminating electric arc, protection contact and housing, improving life of product.
The shape of arc extinction part is generally the U font of direct bending and molding at present.The shortcoming of this arc extinction part is: under the high temperature action of electric arc, arc extinction part easily deforms, and inwardly shrink two sides.Because making contact and arc extinction part distance, distortion diminishes, arcing Distance Shortened, and electric arc cannot be elongated fast and be extinguished, and directly causes the serious scaling loss of contact, reduces the life-span of product; Calcination housing is carried out in after simultaneously a large amount of electric arc can shrink by arc extinction part and the gap of housing generation, very likely causes alternate arc through, thereby makes life of product termination, when serious, after distortion, arc extinction part can come off with housing, clamping stagnation moving contact, cause product failure, cause fire or other accident.
Prior art is out of shape serious situation in order to improve it, adds some features and alleviate on the part being mated.The method can be alleviated distortion reluctantly, but makes design of part more complicated, and technological requirement and the course of processing have all added large difficulty, has increased the cost of product.
Summary of the invention
The utility model overcomes the problem that prior art exists, and a kind of simple in structure, novel arc extinction part for contactor that production cost is low is provided.
Realize above-mentioned purpose, the utility model adopts following technology: a kind of arc extinction part for contactor, this arc extinction part is arranged and is formed by the bending of metalwork one, there is two block-shaped identical side plates and a transverse slat between biside plate, biside plate is symmetricly set on the both sides of transverse slat, the transition position that is connected between biside plate and transverse slat all meets at right angles, the upper and lower side of biside plate all protrudes transverse slat setting, the middle part of transverse slat offers through hole, it is characterized in that: described two right angle places are respectively arranged with the reinforcement point that punching press forms, reinforcement point is in depression at the lateral surface at right angle, the corresponding medial surface at right angle forms projection.
By adopting such scheme, this reinforcement point structure has good supporting role to two of arc extinction part side plates, can make the structure of arc extinction part more stable, thereby makes it not yielding under the high temperature action of electric arc; This reinforcement point structure has increased the surface area of arc extinction part simultaneously, is beneficial to heat radiation, accelerates arc extinction, and then improves the life-span of product.
Further setting of the present utility model is: the reinforcement point on described two right angles is respectively arranged with two, and the reinforcement point on two right angles becomes to be symmetrical arranged, and the height of projection of described right angle medial surface is 0.8-1cm; Described depression two ends extend on side plate and transverse slat, and described protruding two ends extend on side plate and transverse slat.
By adopting such scheme, be to further optimization of the present utility model, its object is mainly the effect that increases reinforcement point.
Below in conjunction with drawings and embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model embodiment;
Fig. 2 is the structural representation that the utility model embodiment reflects arc extinction part medial surface;
Fig. 3 is the utility model embodiment plan structure schematic diagram.
Specific embodiment
As shown in Fig. 1-Fig. 3, a kind of arc extinction part for contactor, this arc extinction part is arranged and is formed by the bending of metalwork one, there is two block-shaped identical side plates 1 and a transverse slat 2 between biside plate 1, biside plate 1 is symmetricly set on the both sides of transverse slat 2, the transition position that is connected between biside plate 1 and transverse slat 2 all meets at right angles 12, the upper and lower side of biside plate 1 all protrudes transverse slat 2 and arranges, the middle part of transverse slat 2 offers through hole 21, these above-mentioned technical characterictics are also to have embodiment in the prior art, so be not here just described in detail, in the present embodiment, 12 places, described two right angle are respectively arranged with the reinforcement point 121 that punching press forms, the lateral surface at 121 right angle, reinforcement point 12 is in depression 1211, the corresponding medial surface at right angle 12 forms projection 1212, by adopting such scheme, these reinforcement point 121 structures have good supporting role to two of arc extinction part side plates, can make the structure of arc extinction part more stable, thereby make it not yielding under the high temperature action of electric arc, this reinforcement point structure has increased the surface area of arc extinction part simultaneously, is beneficial to heat radiation, accelerates arc extinction, and then improves the life-span of product.
In the utility model embodiment, described two 12Shang reinforcement points, right angle 121 are respectively arranged with two, and 121 one-tenth of 12Shang reinforcement points, two right angles are symmetrical arranged, and the projection 1212 of described right angle 12 medial surfaces is highly 0.8-1cm; Described depression 1211 two ends extend on side plate 1 and transverse slat 2, and described protruding 1212 two ends extend on side plate 1 and transverse slat 2.
The utility model discloses, and is the one of preferred embodiment, and local change or modification and come from technological thought of the present utility model and be easy to by haveing the knack of the people of this technology the person of knowing by inference such as, does not all take off patent category of the present utility model.
