Abstract

A kind of relay, is applied in automatic control circuit, belongs to a kind of electric switch, including magnetic circuit part, and magnetic circuit part includes yoke, and yoke is equipped with the yoke through-hole being inserted into for rivet, and yoke through-hole is equipped with groove, the outer openings of groove close to coil one end.The utility model is equipped with groove close to coil one end in yoke through-hole, and the outer openings of groove, therefore, when fixture mount needs to withstand rivet right end, fixture mount can be inserted into groove by worker from yoke side, and in other words, fixture mount is changed to be inserted into from yoke side by original move along yoke through-bore axis direction, therefore, the movement of fixture mount will no longer be influenced by coil outermost wall away from the distance between yoke side wall；It is not influenced by coil outermost wall away from distance between yoke side wall just because of fixture mount intensity, also ensures that intensity when fixture mount withstands rivet right end in this way, and then guarantee the fastness of rivet, elastic slice is enable reliably to be riveted on yoke side wall.

Description

A kind of relay

Technical field:

It is especially one kind when riveting elastic slice, it can be ensured that fixture mount is strong the utility model relates to a kind of electric switch The relay of degree.

Background technique:

Existing relay is generally as shown in Figure 3 and Figure 4, it is usually by groups such as magnetic circuit part, contact portion and pedestals At magnetic circuit part includes yoke 53, armature 57, elastic slice 50, iron core 56 and the coil 55 being wrapped on 56 periphery wall of iron core, yoke Iron 53 connects on the base, and 50 one end of elastic slice is connect with armature 57, and 50 other end of elastic slice is riveted on 53 side of yoke by rivet 52 On wall, before elastic slice 50 and yoke 53 rivet, worker is connected to yoke firstly the need of by 56 bottom of iron core for being enclosed with coil 55 On iron 53, then elastic slice 50 is riveted on 53 side wall of yoke by rivet 52 again, when riveting, rivet 52 is inserted into bullet simultaneously In piece through-hole 51 and yoke through-hole 58, in order to ensure elastic slice 50 is riveted on 53 side wall of yoke by rivet 52 securely, worker this When can use a kind of fixture, be connected with fixture mount on the fixture, fixture mount is equipped with convex in shrinkage pool 54 for being inserted into It rises, which is used for when riveting 52 left end of rivet, and the right end of rivet 52 is given and is firmly withstood.Above-mentioned elastic slice 50 and yoke 53 Exist when riveting with next shortcoming: since fixture mount drives protrusion is inserted into along the axis direction of yoke through-hole 58 In shrinkage pool 54, and 55 outermost wall of coil being wrapped on iron core 56 is usually all smaller away from the distance between 53 side wall of yoke, This has resulted in the protrusion in fixture mount cannot smoothly be inserted into shrinkage pool 54 sometimes, for this purpose, worker has in fixture Think hard on bracket, i.e., by the thinner of fixture mount setting, but its too thin intensity of fixture mount can be obvious insufficient, works as riveting in this way When connecing 52 left end of rivet, fixture mount can be bending to the right because of left end stress, causes the riveting of 52 left end of rivet insecure, thus not Reliably elastic slice 50 can be riveted on 53 side wall of yoke.

Utility model content:

The technical problems to be solved in the utility model is to provide one kind when elastic slice to be riveted on yoke side wall, can Ensure the relay of fixture mount intensity.

The technical solution of the utility model is to provide a kind of relay having following structure: including magnetic circuit part, Magnetic circuit part includes yoke, and yoke is equipped with the yoke through-hole being inserted into for rivet, wherein yoke through-hole is equipped with close to coil one end Groove, the outer openings of groove.

A kind of relay described in the utility model, wherein recess sidewall can be equipped with draft.

A kind of relay described in the utility model, wherein draft can be 30 °.

After using the above structure, compared with prior art, a kind of relay of the utility model have the advantage that with it is existing Technology is different, and the utility model relay is equipped with groove, and the outer openings of groove close to coil one end in yoke through-hole, because This, when fixture mount needs to withstand rivet right end, fixture mount can be inserted into groove by worker from yoke side, in other words It says, fixture mount is changed to be inserted into from yoke side by original move along yoke through-bore axis direction, therefore, the shifting of fixture mount Dynamic no longer to be influenced by coil outermost wall away from the distance between yoke side wall, correspondingly, the intensity of fixture mount will not be by This is influenced, and is not influenced by coil outermost wall away from distance between yoke side wall just because of fixture mount intensity, therefore, fixture branch The thickness that frame can be set a bit, also ensures that intensity when fixture mount withstands rivet right end in this way, and then guarantees that rivet is left The fastness when riveting of end, enables elastic slice to be reliably riveted on yoke side wall.

The setting of draft can significantly facilitate fixture mount and be inserted into groove.

Fig. 2 is the stereo amplification figure of yoke in Fig. 1；

Fig. 3 is the exploded structural schematic diagram of prior art relay；

Fig. 4 is the main view enlarged drawing of yoke in Fig. 3.

Specific embodiment:

A kind of relay of the utility model is described in further detail with reference to the accompanying drawings and detailed description:

As depicted in figs. 1 and 2, in this embodiment, a kind of relay of the utility model includes magnetic circuit part, connects Contact portion point and pedestal (not shown), magnetic circuit part include yoke 4, armature 7, elastic slice 1, iron core 6 and are wrapped in iron core 6 Coil 5 on periphery wall, 6 bottom of iron core are connected in the jack 9 that yoke 4 is equipped with, and yoke 4 connects on the base, elastic slice 1 one End connect with armature 7, and 1 other end of elastic slice passes through rivet 2 and is riveted on 4 side wall of yoke, and yoke 4 is equipped with being inserted into for rivet 2 Yoke through-hole 8, there are two yoke through-holes 8, and two yoke through-holes 8 are all provided with fluted 3 close to 5 one end of coil, two grooves 3 it is outer Side is open, and 3 side wall of groove is equipped with draft, and draft is 30 °.Contact portion in present embodiment is conventional The prior art, details are not described herein for specific structure.
