Description
Technical field
The utility model relates to the common improvement and the optimization of a kind of under-voltage release and a kind of shunt release structure, belongs to low voltage electrical apparatus industry.
Background technology
At present, under-voltage release and shunt release generally all are independent designs structurally, do not utilize the general character on its structure and the operating characteristics to be designed for uniformity, thereby part is many, cost is high.
Under-voltage release adopts two-stage amplifying type structure, assembly should get when electric at coil moving adhesive unshakable in one's determination is locked, play the suction effect that helps again, therefore higher to every technical requirement of part in the assembly, number of spare parts is too much again, not only reduce reliability of products, increased the cost of product simultaneously.
The conversion portion of shunt release adopts the top sensitive switch contact form of directly touching, because the sensitive switch closing stroke is very little, this just requires straight top mechanism's fitted position and part processing dimensional accuracy on the shunt release very high, and require circuit breaker to be transferred to that shunt release directly pushes up that part of fitted position of mechanism and the part processing dimensional accuracy is very high, be unfavorable for the batch process of product like this, increased manufacturing cost again.
Market competition is fierce day by day, and it is low that circuit breaker accessory has been proposed cost, highly versatile, and the reliability height, the requirements at the higher level that modularization is good, traditional design can not satisfy.
Summary of the invention
The purpose of this utility model is to provide a kind of device for under-voltage releasing equipment and shunt release of shared same unit box of simple in structure, safe and reliable, with low cost, highly versatile.
The technical scheme that provides according to the utility model, the release that has pull bar comprises the coil that is installed in the pedestal, with the lid that is installed on the pedestal, cored on coil, it is characterized in that: the upper right side at pedestal is provided with bearing pin, and connecting on bearing pin can be around the pull bar of bearing pin rotation, and the middle part of pull bar contacts with iron core, torsion spring is set on pedestal, turns round arm and be pressed on the pull bar for one of this torsion spring.
Above-mentioned coil can be a kind of under-voltage release coil, corresponding iron core then is the under-voltage release iron core, in the lower right side of pedestal rotating shaft is set, and the middle part of push rod is articulated in this rotating shaft, one end of push rod contacts with pull bar, and the other end of push rod stretches out the hole that is arranged at the pedestal lower end.
Described coil also can be a kind of shunt release coil, corresponding iron core is the shunt release iron core, and side is provided with column in the pedestal lower-left, and the middle part of driving lever is hinged on the column, one end of driving lever stretches out the hole that is arranged at the pedestal lower end, and the other end contacts with the sensitive switch that is arranged at the pedestal left side.
The upper end of pull bar is rotatably connected on bearing pin, and the middle part of pull bar is provided with the end that allows iron core and inserts its interior through hole, and hook-shaped handle is set on pull bar.
The utility model has the advantages that: 1, because the shunt release of the present utility model overall dimension and the same internal cavities the same with under-voltage release; External client's installation requirements have not only been satisfied in this a kind of design, have reduced costs such as mfg. moulding die, material storage again.2, in order to reduce the under-voltage release volume, traditional method is to adopt the Sucking-assisting type device for under-voltage releasing equipment, because the structure of this release is too complicated.Some misoperations or the phenomenon of being failure to actuate in use often appear; The Sucking-assisting type under-voltage release of the utility model design simplifies the structure, and is both energy-conservation, reliable again.3, the closed circuit breaker of existing unit box, the conversion portion of its shunt release all adopts the direct-push structure, because the requirement of the closing stroke of sensitive switch is very little, causes the conversion of shunt release conversion portion unreliable, and design accuracy required high phenomenon; Shunt release conversion portion of the present utility model is a kind of rotational structure, the positive good utilisation of this structure the little characteristics of sensitive switch closing stroke, make sensitive switch be in closure state earlier, then by rotating a distance that needs only greater than the sensitive switch stroke, just can make sensitive switch be in off-state, this structural design is simple, reliable, and parts design required precision not higher position can reach safe transformation.
