The contact of pass causes the junction closure of contact disjunction or the disconnection of closure.It goes to control by the change of make and break contact opening and closing state
Circuit and motor.
Limit switch is a kind of common low current master control electrical apparatus, is to protect switchette not by external force, water, oil, dirt
Angstrom equal infringement and be loaded into the switch in metal shell or plastic shell.In electric control system, limit switch
Effect is to realize sequential control, the detection of location control and location status, for controlling the stroke and position limitation protection of mechanical equipment.
Limit switch rated value refers generally to the amount of the guarantee standard as switching characteristic and performance, such as rated current, voltage rating etc., with
Premised on specific condition.Bit switch, which has contact finger, realizes the function of switch using the machinery folding of contact.Limit switch connects
Touching form constitutes the mode of the electrical imput output circuit of contact according to various uses.Limit switch in the prior art is usually made
Lead to limit switch during use almost without the protective device for being directed to limit switch for the use of individual component, by
It is excessive in the power acted in shaft, cause limit switch inner components to be damaged.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of limit switches with protective device, can effectively prolong
The service life of long limit switch prevents its inner body from damaging.
The present invention is achieved by the following technical solutions.
Limit switches, institute is fixedly mounted in a kind of limit switch with protective device, including box body, the box body bottom
It states and is provided with cable hole on box body on position corresponding with the cable entries on limit switch, turn on box body and limit switch
It is provided with shaft mouth on the corresponding position of axis, sliding block is provided in the shaft of the limit switch, one end of the sliding block connects
It is connected to compressed spring, the other end of the compressed spring is connected with baffle, and the baffle is placed in the bottom of box body, and baffle
Side is the side of box body, and the other side is partition, and the partition is vertically arranged with baffle, wherein the two sides of box body, partition, box
One space for accommodating baffle is formed on the top of body, and there are two opposite limited block, the limits for setting between the baffle and sliding block
Position block is fixedly mounted on the bottom of box body, and limited block is close to the inside of partition and the inside of box body side respectively.
Specifically, the bottom of the sliding block is connect by bolt with shaft.
Specifically, upper cover is provided at the top of above-mentioned box body, the upper cover is bolted at the top of box body.
Specifically, cushion is bonded on the inner side edge of above-mentioned shaft mouth.
From the above technical scheme, it can be seen that the beneficial effects of the present invention are:
A kind of limit switch with protective device provided by the invention, performance are stablized, and by the way that compressed spring is arranged, can have
The guarantee shaft of effect has a buffer function, is not in that deflection angle is excessive, causes to limit when encountering biggish rotation
The phenomenon that switch internal part damages, while it being provided with cushion at shaft mouth, it is broken to can effectively prevent shaft
The phenomenon that shaft is damaged when bad shaft mouth and shaft and box body are touched.
