Description
Technical field
The utility model 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.
The applicant's earlier application a kind of contact plate of contactor, as shown in China Patent Publication No. 103094008A, this contact plate comprises fixed contact support portion and connecting portion, described connecting portion is made up 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 at least provided with two adjutages that are one and have width with conductive metal sheet, and described adjutage forms described fixed contact support portion.
This contact plate has simple in structure, the effect that improves heating current and effectively reduce production costs, but in actual processing, opposite face after conductive metal sheet turnover and conductive metal sheet turnover is affixed to setting, in actual processing, because conductive metal sheet exists elasticity, after bending process, in fact be difficult to make two opposite faces of the conductive metal sheet after bending bonded to each other, between the two because of the elasticity of conductive metal sheet self, and always there is certain interval, the existence in these gaps, by the contact resistance greatly having improved between two opposite faces of conductive metal sheet, cause contact plate temperature rise, the consumption of contact plate self energising energy is large.
In addition on the one hand, due to the installation for busbar on the outside, two sides up and down of the connecting portion of contact plate.Therefore, must ensure the surfacing of two sides up and down of connecting portion, can not have bossing, could ensure the conductive attachment between busbar and connecting portion.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provides a kind of structure to arrange rationally, and contact resistance is little, assembles the contact plate of contactor easy to process.
For achieving the above object, the technical solution of the utility model is, on contact plate, be provided with fixed contact support portion and connecting portion, also include contact plate body, contact plate body includes the first connecting plate and is integrally formed at least two of the first connecting plate one side the adjutage with width, described adjutage forms fixed contact support portion, it is characterized in that: also comprise the second connecting plate, the side that described the second connecting plate is fixedly stacked at the first connecting plate forms connecting portion, on the first described connecting plate face relative with the second connecting plate, be provided with at least one tapped blind hole, on the second described connecting plate, be provided with the through hole with the corresponding coupling of tapped blind hole, also include the trip bolt matching with tapped blind hole, trip bolt is provided with head of screw, the outer end of described through hole offers the counterbore that holds head of screw on the outer face of the second connecting plate, described trip bolt is connected and fixed in tapped blind hole through through hole and the inner, and the head of screw outer face of trip bolt is positioned at counterbore the outer face lower than the second connecting plate.
By this setting, directly adopt the mode of the second connecting plate stack to thicken formation connecting portion, this syndeton is reliable and stable, and, by be provided with tapped blind hole on the first connecting plate, and be provided with the through hole with counterbore on the second connecting plate, by trip bolt, the first connecting plate and the second connecting plate are installed, this structure, screw connecting hole is can't see in the front of the first connecting plate, good looking appearance; On the second connecting plate, for having the through hole of counterbore, head of screw (sunk screw, pan head screw, fillister head screw or other bolts, screw) is sunken in counterbore, and its top is lower than the second connecting plate outer surface.Trip bolt only plays the temporary fixed effect between contact plate and connecting plate, does not affect being connected between upper and lower both sides external conductive row and contact plate, connecting plate.
Further arrange is on described the second connecting plate and the first connecting plate, to be provided with multiple corresponding busbar connecting holes mutually up and down.By this busbar connecting hole, convenient that busbar is fastening with being connected of the first connecting plate, the second connecting plate.
Base and left and right side that further setting is described the second connecting plate flush up and down mutually with base and the left and right side of the first connecting plate.This setting, good looking appearance is assembled easy to process simultaneously.
The outer end that further setting is described each adjutage is provided with bending end, in the outside wall surface of bending end, is fixed with fixed contact.
Further arranging is that described adjutage is provided with three.Thus, form the three extremely in parallel of fixed contact support portion, increase the contact area of contact, reduce interelectrode contact resistance in parallel, reduce the contact resistance that is connected with busbar, reduce the energy loss of contactor contact component self, the temperature rise of reduction contact component.
In sum, the utility model has the advantages that reasonable in design, easy to assembly reliable, contact resistance is little, and the loss of contact plate self-energy is little.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
