Abstract
The utility model relates to a contactor, particularly an additional device used for the contactor. According to a design proposal provided by the utility model, a spring is arranged on an indicating piece, and one end of the spring is supported on the bottom of the indicating piece; the other end of the spring is in contact with a pressing plate which can move relatively to the upper end of the indicating piece, and the length of the pressing plate is greater than the maximum length of the upper end of the indicating piece. The utility model can be used for testing the reliability of mechanism action and the attract and release state of a reaction contactor, and has the characteristics of convenient assembly, flexible action, beautiful appearance, safety, etc.
Description
Technical field
The utility model relates to contactor, specifically a kind of attachment device that is used on the contactor.
Background technology
Contactor is mainly used in remote connection and branch deenergizing and control alternating current motor, and for contactor, the reliability of its mechanism action is an important index.In the prior art, because structural design is unreasonable, the reliable in action of the contactor mechanism that assembles is not ideal; And in normal operation, the user can't in time understand the course of action of contactor.
Summary of the invention
The purpose of this utility model is to design a kind of contactor indication piece, utilizes this indication piece can understand the operating state of contactor intuitively, so that control appliance and protection personal security.
According to design provided by the utility model, on indication piece, place spring, one end of this spring withstands the bottom support of indication piece, and this bottom support forms a complete sealing surface, the other end with can contact with respect to the pressing plate that move the upper end of indication piece, the length of pressing plate is greater than the maximum length of indication piece upper end.
Indication piece is tubular, place spring in the cavity of indication piece, pressing plate passes the cavity of indication piece, and stretch out outside the cavity of indication piece at the two ends of pressing plate, pressing plate top can with the last end in contact of indication piece, the groove that the two ends that allow pressing plate move up and down is set on the two side of tubular indication piece.
It is shaft-like that indication piece is, and at the two ends up and down of shaft-like indication piece base plate and top board is set respectively, and at the outside of shaft-like indication piece sleeve spring and pressing plate, the two ends up and down of this spring contact with base plate with pressing plate respectively.
The advantage of the utility model system is: after being provided with indication piece on the contactor, under the cold situation of contactor, by pressing indication piece, can understand contactor mechanism reliable in action, have or not the mechanism blockage phenomenon, prevent to damage the contactor parts.When contactor was worked, the user can get information about the working condition of contactor, as was in and connects or open mode, and operating state is not clear to cause unnecessary loss to the user to avoid occurring.

Embodiment
As shown in the figure: a kind of form of indication piece is that indication piece 1 is tubular, in the cavity of indication piece 1, place spring 3, pressing plate 2 passes the cavity of indication piece 1, stretch out outside the cavity of indication piece 1 at the two ends of pressing plate 2, so that after being installed on indication piece 1 in the contactor 8, the hole that is positioned on contactor 8 shells can be stretched out in the upper end of indication piece 1, and pressing plate 2 then is limited in the enclosure.Pressing plate 2 top can with the last end in contact of indication piece 1, the groove that the two ends that allow pressing plate 2 move up and down is set on the two side of tubular indication piece 1, because a complete seal face is formed on the bottom of tubular indication piece 1, therefore, the spark that has produced when having stopped contactor 8 work is scurried out from indication piece 1, scalds the problem of finger.
The another kind of form of indication piece is that indication piece 1 is shaft-like, two ends up and down at shaft-like indication piece 1 are provided with base plate and top board respectively, at the outside of shaft-like indication piece 1 sleeve spring 3 and pressing plate 2, the two ends up and down of this spring 3 contact with base plate with pressing plate 2 respectively, the length of pressing plate 2 is greater than the length of top board, so that after being installed on indication piece 1 in the contactor 8, the hole that is positioned on contactor 8 shells can be stretched out in the upper end of indication piece 1, pressing plate 2 then is limited in the enclosure.Because base plate forms a complete seal face, therefore, the spark that has produced when having stopped contactor 8 work is scurried out from indication piece 1, scalds the problem of finger.
During work, the contact of contactor 8 has a little pressure to indication piece 1,3 pairs of indication pieces 1 of spring have a counter-pressure simultaneously, do not load onto position such as Fig. 2 of this indication piece 1, the assembling back is as Fig. 3, and when contactor 8 adhesives, contact is supported closed, indication piece 1 is subjected to the pressure of spring 3 and tangible moving is inwardly arranged, specifically shown in Fig. 4,5.When contactor 8 is in off-state; indication piece 1 makes progress under the counter-force effect of main contact 4; indication piece 1 contacts with main contact 4; when contactor 8 is in on-state; main contact 4 adhesives; inwardly motion; indication piece 1 is under the less reaction spring effect in inside; also inwardly motion; but behind the indication piece 1 motion certain distance with regard to stop motion; and the still inwardly motion of the main contact 4 of contactor 8, up to complete adhesive, like this indication piece 1 with regard to and main contact 4 certain distance is arranged; this segment distance can play certain insulating effect; can bear the withstand voltage of 3500V 1min and be unlikely to puncture, be not intended to contact indication piece 1 and electric shock accidents does not take place, good fail safe is arranged with the protection user.
