Technical field:
The present invention relates to electric field, relate in particular to miniature circuit breaker, particularly a kind of fast closing mechanism that is used for miniature circuit breaker.
Background technology:
In the prior art, the fast closing mechanism of miniature circuit breaker is made of handle, handle torsion spring, retainer, connecting rod and contact system.During closing operation, handle rotates, and drives the retainer motion, the motion of retainer drivening rod, and connecting rod drives the contact system closure.In operating process, handle torsion spring moment increases with the handle rotational angle, and contact system is closed in the increase process gradually of torsion spring moment.Therefore the closing speed of contact system is still relevant with dependent manual operation speed, so just has influence on the reliability of combined floodgate and the operation lifetime of product.
Summary of the invention:
The object of the present invention is to provide a kind of fast closing mechanism that is used for miniature circuit breaker, the technical problem that the closing speed that the described this fast closing mechanism that is used for miniature circuit breaker will solve the middle-size and small-size circuit breaker of prior art is influenced by dependent manual operation speed.
This fast closing mechanism of miniature circuit breaker that is used for of the present invention is by handle, the handle torsion spring, retainer, U type connecting rod, snap close, locating part, the contact connecting rod, contact mechanism and Shell of circuit breaker constitute, described snap close is fixedly installed in the Shell of circuit breaker, described handle is connected with Shell of circuit breaker with Bearning mechanism by axle, described handle torsion spring, retainer, U type connecting rod, contact connecting rod and contact mechanism are arranged in the Shell of circuit breaker, the contact connecting rod is connected with contact mechanism, wherein, one end of described handle is provided with a boss, the middle part of handle is provided with a rotation hole, described retainer is arranged in the described rotation hole, be provided with a spring connecting hole and a tie rod holes in the retainer, one end of described handle torsion spring is connected in the described spring connecting hole, the other end of handle torsion spring is fixed on the handle, one end of described U type connecting rod is arranged in the tie rod holes in the retainer, described snap close is provided with an orbit hole, the other end of U type connecting rod passes described orbit hole and is connected with described contact connecting rod, described locating part is arranged in the Shell of circuit breaker by rotating shaft, and be positioned at the side of snap close, the edge of locating part is provided with one the one C type groove and one the 2nd C type groove, a described C type groove overlaps with orbit hole, described the 2nd C type groove is arranged in the rotational travel of the boss of handle, is provided with a locating part torsion spring between locating part and the Shell of circuit breaker.
Further, described retainer is 8 fonts, and the lower end diameter of retainer is less than upper end diameter, and the upper end of retainer is arranged in the rotation hole of handle, and described tie rod holes is arranged on the lower end of retainer.
Operation principle of the present invention is: the actuating handle rotates to the combined floodgate direction, and handle drives the retainer motion, and retainer drives the link motion of U type, and U type connecting rod slides in the snap close orbit hole, and drives the contact link motion.When U type connecting rod is run on the locating part that overlaps with the snap close orbit hole C type groove, U type connecting rod stops to continue to slide, U type connecting rod makes the retainer stop motion, contact system is also failed the rotation that is triggered, when continuing the operating grip rotation, the angle between retainer and the handle changes, and handle torsion spring moment is increased, when handle was rotated further, handle torsion spring moment continued accumulation energy.When handle turns to the 2nd C type groove on the boss collision locating part, boss is stirred locating part and is rotated, and a C type groove departs from the snap close orbit hole on the locating part, thereby discharges U type connecting rod, U type connecting rod slides rapidly under the effect of handle torsion spring moment, drives contact mechanism and realizes quick-make.
The present invention compares with prior art, and its effect is actively with tangible.The present invention utilizes locating part spacing to U type connecting rod in miniature circuit breaker, and utilize the spring accumulation energy, when turning to critical angle, stirs by handle locating part, the energy of spring accumulation is discharged in the contact mechanism, thereby realize the quick-make of contact, solved the problem that the closing speed of miniature circuit breaker is influenced by dependent manual operation speed, the reliability and the fail safe that have improved breaker closing have also improved the operation lifetime of circuit breaker simultaneously.
