Abstract

The utility model discloses a relay. The relay comprises a base (1), a push plate (2) and an armature (3), wherein the armature (3) is clamped on the base (1); the push plate (2) props against the armature (3); a transverse clamping groove (11) opening towards the side surface is formed on the side surface of the base (1); and the push plate (2) is clamped in the transverse clamping groove (11). When the relay adopting the above structure is assembled, the push plate is transversely pushed into the transverse clamping groove from the front side of the base, so that the assembly is very simple and the maintenance is convenient; meanwhile, the structure can be assembled by the aid of a conventional special equipment, so that the assembly efficiency is greatly improved.

Description

Relay

Technical field

The utility model relates to electronic control device, specifically is a kind of relay.

Background technology

Relay is a kind of electronic control device, is applied to usually play effects such as automatic adjusting, safeguard protection, change-over circuit in the automatic control circuit in circuit.Relay generally comprises parts such as sound reed, pedestal, yoke, coil, armature, shell fragment, push pedal, wherein, parts such as sound reed, yoke, armature, coil, shell fragment, push pedal all are mounted on the pedestal, coil is installed on the pedestal by skeleton, one end of yoke is riveted on the skeleton, the other end is a free end, push against with armature, shell fragment is connected with armature and is installed on the pedestal, one end Elastic Contact of one end of armature and push pedal, the other end of push pedal contacts with movable contact spring, and the sound reed is installed on the pedestal.In the relay of prior art, push pedal is to insert from front to back in the pedestal, therefore, there is following shortcoming in this structure: because relay is small-sized electronic control device, it assembles generally based on craft, so its rigging error is bigger, therefore, production efficiency is low; If use special equipment to assemble, it locatees more complicated, needs special positioner, thereby increases production cost; In addition, mounting structure from front to back correspondingly causes the front end of push pedal to have movable contact spring to block, and makes the taking-up of push pedal very difficult, so maintenance is very inconvenient.

The utility model content

Technical problem to be solved in the utility model is that a kind of assembling and relay easy to maintenance, that production efficiency is high are provided.

For solving the problems of the technologies described above, the relay that the utility model provides comprises pedestal, push pedal and armature, described armature is connected on the pedestal, described push pedal and armature offset, and described base side mask has the horizontal draw-in groove of opening towards the side, and push pedal is plugged in the horizontal draw-in groove.

After adopting above structure, the utility model compared with prior art has following advantage: because when relay assembles, be that push pedal is laterally pushed horizontal draw-in groove from the front side of pedestal, and then relay1 case on the face shield outside, therefore, assemble very simply, keep in repair also very convenient; Simultaneously, this structure can be used existing special equipment and be assembled, and efficiency of assembling improves greatly.

As improvement, described push pedal is made up of riser and transverse slat, and described transverse slat is plugged in the horizontal draw-in groove of pedestal.After adopting above structure, make push pedal utilize the horizontal draw-in groove of transverse slat and pedestal to peg graft on the one hand, utilize the movable contact spring of riser and relay to offset on the one hand, structure is very simple.

As further improvement, the both sides up and down of described transverse slat and riser junction all have long guide pad, and described long guide pad is the inclined-plane towards the end face of horizontal draw-in groove bottom land.Described transverse slat has short guide pad in the junction with riser, and described short guide pad is positioned at the one side of transverse slat towards horizontal draw-in groove bottom land, and the end face of this weak point guide pad is the inclined-plane.After adopting this structure, make push pedal when inserting the horizontal draw-in groove of pedestal, guide effect arranged, make push pedal more stable when assembling, locate more accurate.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

By the structural representation of the utility model relay of Fig. 1～shown in Figure 3 as can be known, it comprises pedestal 1, push pedal 2 and armature 3, and described armature 3 is connected on the pedestal 1, and described push pedal 2 offsets with armature 3.Described pedestal 1 side has the horizontal draw-in groove 11 of opening towards the side, and push pedal 2 is plugged in the horizontal draw-in groove 11.

Described push pedal 2 is made up of riser 21 and transverse slat 22, and described transverse slat 22 is plugged in the horizontal draw-in groove 11 of pedestal 1.

Described transverse slat 22 all has long guide pad 23 with the both sides up and down of riser 21 junctions, and described long guide pad 23 is the inclined-plane towards the end face of horizontal draw-in groove 11 bottom lands.

Described transverse slat 22 has short guide pad 24 in the junction with riser 21, described short guide pad 24 is positioned at the one side of transverse slat towards horizontal draw-in groove 11 bottom lands, and the end face of this weak point guide pad 24 is the inclined-plane.

In the time of on pedestal 1 that push pedal 2 is packed into, only the side with long guide pad 23 and short guide pad 24 in the push pedal 2 need be aimed at horizontal draw-in groove 11 on the pedestal 1 and insert and get final product, be assembled at last again cover upward relay1 case just finish.When relay maintenance or when regulating, only need relay1 case is taken down, with push pedal 2 extrapolated getting final product from horizontal draw-in groove 11 gently.
