Description

A kind of relay Buffer Unit

Technical field

The utility model relates to a kind of relay Buffer Unit.

Background technology

At present, latching relay can be realized often opening with normally closed contact by single channel pulse signal and mutually changes and remember, owing to adopting and being rigidly connected between latching relay armature and push rod cup and locking press button head, when the actuating of relay, electromagnet armature and push rod cup impulsive force and the excess of stroke are excessive, locking press button head bears all impulsive forces of armature spacing, easily causes locking press button head to damage.When armature movement number of times reaches 50,000 left and right, there is wear phenomenon in armature, push rod cup and locking press button head, and after armature puts in place, self-lock switch cannot normal conversion, and relay was lost efficacy.

Utility model content

The purpose of this utility model is to address the above problem, providing a kind of avoids because impulsive force is excessive, the relay Buffer Unit that causes locking press button head to damage, this Buffer Unit can also solve because armature wearing and tearing cause the problem that latching relay cannot normal conversion.

For achieving the above object, the technical solution adopted in the utility model is: comprise the buffer cap being arranged between the armature of relay and the locking press button head of quick-action switch, the joint, top of the bottom of buffer cap and armature; On buffer cap, be arranged with the buffer unit of avoiding locking press button head to damage for playing cushioning effect when the armature movement.

Described buffer unit comprises the spring base being set on buffer cap, and the side of buffer cap is provided with for the boss of buffer spring is installed, and one end of buffer spring is fixed on spring base, and the other end is fixed on boss.

The top of described spring base is provided with the back-up ring for preventing that buffer cap from deviating from.

The inside and outside both sides at described spring base top be respectively arranged with for regulate buffer spring initial pressure the first packing ring and for regulating second packing ring in gap between buffer cap and electromagnet.

The first described packing ring is between spring base inside top and buffer spring; The second packing ring is between spring base top outer and back-up ring.

Compared with prior art, the utlity model has following beneficial effect:

The utility model by arranging buffer cap on the armature of relay electromagnet, and buffer unit is set on buffer cap, the utility model is applicable to latching relay, Buffer Unit is fixedly connected with locking press button head, when the actuating of relay, armature promotes Buffer Unit and first action of locking press button, makes relay reach connecting and disconnecting function.Buffer Unit is alleviated electromagnet powered on moment armature impulsive force, and protection locking press button head increases relay useful life.

Further, the utility model is mounting spring seat on buffer cap, and buffer spring is installed in spring base, when Control end passes through a pulse signal, armature motion in relay electromagnet drives whole Buffer Unit motion, when buffer spring is deformed to after certain position, buffer spring promotes spring base and first motion of locking press button, makes often open-the normally closed or normally closed-conversion of often opening of relay tip; After locking press button head puts in place, if armature also continues motion, buffer spring continues distortion, has further avoided the spacing destroyed problem of self-lock switch.

Further, the utility model is provided with back-up ring, and back-up ring can prevent that buffer cap from deviating from, and then prevents that Buffer Unit lost efficacy.

Further, the first packing ring of the present utility model and the second packing ring are respectively used to regulate the initial pressure of buffer spring and the gap between buffer cap and electromagnet, guarantee relay self-lock switch action message, have avoided doing because vibration causes relay misoperation.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model Buffer Unit;

Fig. 2 is the utility model and relay assembly structure schematic diagram.

Wherein, 1 is buffer cap; 2 is spring base; 3 is buffer spring; 4 is the first packing ring; 5 is the second packing ring; 6 is back-up ring; 7 is quick-action switch; 8 is locking press button head; 9 is armature; 10 is electromagnet.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, the utility model comprises the buffer cap 1 being arranged between the armature 9 of relay and the locking press button head 8 of quick-action switch 7, the joint, top of the bottom of buffer cap 1 and armature 9; On buffer cap 1, be arranged with for play the buffer unit that cushioning effect avoids locking press button head 8 to damage when armature 9 moves.Buffer unit comprises the spring base 2 being set on buffer cap 1, and the side of buffer cap 1 is provided with for the boss of buffer spring 3 is installed, and one end of buffer spring 3 is fixed on spring base 2, and the other end is fixed on boss.The top of spring base 2 is provided with back-up ring 6 can prevent that buffer cap 1 from deviating from, and prevents that Buffer Unit lost efficacy.The inside and outside both sides at spring base 2 tops are respectively arranged with first packing ring 4 that can regulate buffer spring 3 initial pressures and the second packing ring 5 that regulates gap between buffer cap 1 and electromagnet, guarantee relay action message, have avoided doing because vibration causes relay misoperation.The first packing ring 4 is between spring base 2 inside top and buffer spring 3; The second packing ring 5 is between spring base 2 top outer and back-up ring 6.Principle of the present utility model and the course of work:

As shown in Figure 2, the utility model comprises that buffer cap 1, the first packing ring 4, the second packing ring 5 and buffer spring 3 are fixed on the Buffer Unit on spring base 2 by back-up ring 6.Buffer Unit is applicable to latching relay, when Control end passes through a pulse signal, armature 9 motions in relay electromagnet 10 drive Buffer Unit motion, when buffer spring 3 is deformed to after certain position, buffer spring 3 promotes spring bases 2 and moves together with locking press button head 8 moving parts, makes often open-the normally closed or normally closed-conversion of often opening of relay quick-action switch 7 contacts; After locking press button head 8 moving parts put in place, if armature 9 continues motion, buffer spring 3 continues distortion, until armature 9 motions put in place, has avoided armature 9 because stroke is excessive or the excess of stroke is damaged locking press button head 8.

Above content is only explanation technological thought of the present utility model; can not limit protection range of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the protection range of the utility model claims.
