Description
Technical field
The present invention relates to a kind of contact plate of contactor.
Background technology
In order to improve the heating current of contactor, can adopt the method for contacts of contactor parallel running.The contact plate of A.C. contactor generally includes fixed contact support portion and connecting portion, and in order to improve heating current, the thickness of connecting portion need to be greater than the thickness of fixed contact support portion.In prior art, during the contacts of contactor parallel running, contact plate roughly adopts two kinds of different modes.the first is that fixed contact support portion and connecting portion employing are split type, and both adopt connector to fix, referring to accompanying drawing 1, both carry out its fixed contact support portion 1 and connecting portion 2 cutting by different moulds to conductive metal sheet and form, therefore produce trouble and improved cost, and both connect by connector, volume is larger, increase contact resistance, reduced properties of product, the second is the part 3 by two integral body, 4 consist of, referring to accompanying drawing 2, and each part 3, 4 all comprise connecting portion 301, 401 and fixed contact support portions 302, 402, two parts 3, 4 connecting portion 301, 401 are stacked to constitute the integral body of contact plate, and although this kind scheme is two parts 3, 4 can be by identical mould to part 3, 4 carry out whole cutting, but two parts 3, 4 fixed contact support portion 302, 402 need in the opposite direction, and bending just can make two parts 3, 4 are stacked to constitute contact plate integral body, therefore have the inconvenient shortcoming of processing, number of spare parts needs pairing, and due to two parts 3, 4 connecting portion 301, 401 are stacked, and are difficult to guarantee both connecting portions 301, the compactness that is affixed between 401 when compactness is bad, has increased equally contact resistance, thereby has reduced properties of product, then and, when conductive metal sheet is carried out cutting, due to a part 3, one of 4 cutting fixed contact support portion 302, 402, the waste material that therefore produces is more, and causes the waste of conductive metal sheet.And when A.C. contactor had multiple current specification, above-mentioned both schemes in the prior art, were all the width dimensions by the change contact plate, thereby need different moulds carry out cutting to conductive metal sheet, thereby improved production cost; And, in the situation that the width of the fixed contact support portion 302,402 of contact plate changes, need to also need to change with the base plate of the adaptive A.C. contactor of fixed contact support portion 302,402 width, further improved production cost.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of simple in structure, improve heating current, the contact plate of the contactor that effectively reduces production costs.
For achieving the above object, the invention provides following technical scheme: a kind of contact plate of contactor, comprise fixed contact support portion and connecting portion, described connecting portion is made of the conductive metal sheet turnover of the general flat with thickness, and after described conductive metal sheet turnover, opposite face is affixed setting, other sides except turnover place of described connecting portion are provided with two adjutages that are one and have width with conductive metal sheet at least, and described adjutage consists of described fixed contact support portion.
By adopting technique scheme, during production, can be by mould to a cutting of conductive metal sheet, and the contact plate for the different model A.C. contactor, can carry out cutting to the conductive metal sheet of different-thickness by identical mould, thereby the width dimensions that need not to change contact plate just can be suitable for the A.C. contactor of different model specification; Connecting portion is made of conductive metal sheet turnover, and fixed contact support portion and connecting portion are and are wholely set, and have reduced contact resistance, have improved heating current, have strengthened heat radiation and conductivity.
The present invention further arranges: described each adjutage is placed in the opposite side of turnover place of described connecting portion, and each adjutage is placed in the same side of conductive metal sheet.
By adopting technique scheme, but conductive metal sheet just cutting be the strip that two adjutages are placed in the same side, effectively reduced the generation of cutting waste material, improved resource utilization, and further reduced production costs.
The present invention further arranges: described each adjutage is provided with bending end, and described bending end arranges with the direction bending with conductive metal sheet turnover opposite direction, is fixed with fixed contact on the outside wall surface of bending end.
By adopting technique scheme, because the overbending direction of bending end is visible face, so arrange, conductive metal sheet makes product more attractive in appearance to the turnover of visible face other direction.
The present invention further arranges: be provided with the vertical bar shaped groove on the wall of described conductive metal sheet, described conductive metal sheet turns down mutually along this vertical bar shaped groove, and the wall of vertical bar shaped groove both sides is affixed.
By adopting technique scheme, after making the conductive metal sheet turnover, its opposite face can better be affixed, and then reduces contact resistance, raising heating current, enhancing heat radiation and conductivity.
The present invention further arranges: be provided with concavo-convex reticulate pattern on the wall of described conductive metal sheet, after described conductive metal sheet turnover, concavo-convex reticulate pattern consists of the net-point shape contact.
By adopting technique scheme, after making the conductive metal sheet turnover, the site compressive deformation more can reach perfect contact, strengthens heat radiation and conductivity.
The invention will be further described below in conjunction with accompanying drawing.
