Description
Technical Field
The utility model relates to a load switch technical field specifically is a load switch auxiliary contact device on post.
Background
In recent years, with the rapid development of smart grids, a common manual pole-mounted switch is gradually replaced by an intelligent pole-mounted switch, and a pole-mounted load switch is one of the intelligent pole-mounted switches and is mainly used for cutting off rated load current; the conventional load switch realizes the switching of the switching-on and switching-off auxiliary contacts through the rotation of the motor, and the mode of switching the auxiliary contacts by the motor shaft has the defects that: after the switch is operated for a period of time, ablation and abrasion exist among the contacts, poor contact is easily caused, and therefore the reliable use of the switch is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a load switch auxiliary contact device on post can effectively solve the problem among the background art.
The technical scheme for realizing the purpose is as follows: the utility model provides a load switch auxiliary contact device on post which characterized in that: the device comprises an installation shell, a spindle installation plate which is horizontally arranged is connected in the installation shell, a motor is installed on the inner side end face of the spindle installation plate, the output end of the motor extends upwards out of the spindle installation plate and is connected with a pressing plate, movable contacts are respectively arranged on two sides of the end portion of the pressing plate, auxiliary switches which are symmetrically arranged are installed on the spindle installation plate on two sides of the pressing plate and comprise connecting seats, the opposite side faces of the connecting seats are inclined planes, a isosceles trapezoid with a large opening end facing outwards is formed between the inclined planes of the connecting seats on the two sides, an auxiliary contact assembly is connected onto the connecting seats and comprises a plunger sleeve, a sliding groove with an opening at the front end is arranged in the plunger sleeve, a plunger is arranged in the sliding groove in a sliding mode, a limiting step is arranged on the sliding groove and the, the static contact and the movable contact are positioned on the same circumference with the rotation center of the motor as the center of a circle.
Further, the tail end of the plunger sleeve is in threaded connection with the connecting seat.
Further, the connecting seat is fixed on the main shaft mounting plate through a bolt.
The utility model has the advantages that:
the utility model discloses at the during operation, motor drive clamp plate rotates, makes the movable contact of clamp plate tip and the stationary contact of both sides, and the compression corresponds the spring of side auxiliary contact subassembly when movable contact and stationary contact, and the reaction force through the spring makes reliable contact between movable contact, the stationary contact, has improved product reliability, has prolonged product life.
