Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of relays, in particular to a horizontal relay. Background Art
[0002] An electromagnetic relay is an electrical device that uses electromagnetic force to drive mechanical components to move relatively to produce a predetermined response. Generally, it consists of a magnetic circuit part, a moving spring part, and a static spring part. The magnetic circuit part includes an iron core, a skeleton, a coil, an armature, a yoke, and a hook. One end of the hook is installed with the armature, and the other end is hung on the yoke. When the coil passes through current, electromagnetic force is generated, the armature is attracted and contacts the pole face at one end of the iron core, thereby driving the moving contact of the moving spring part to close with the static contact of the static spring part; when the current in the coil disappears, the electromagnetic force disappears, the armature resets and separates from the pole face at one end of the iron core, so that the moving contact of the moving spring part separates from the static contact of the static spring part. In this way, by the contact or separation of the moving contact and the static contact, the purpose of turning on or off the circuit of the external load is achieved.
[0003] Among them, in the bedroom relay, the yoke is L-shaped, including a first section for connecting with the iron core and a second section for engaging with the hook. When installing the yoke, the rivet is passed through the first section to connect with the iron core. However, when the rivet is pushed towards the iron core direction, the rivet will give the iron core a rotational force, and the head of the iron core deforms to achieve riveting with the yoke. But at this time, the yoke will also be subjected to a rotational force and rotate, so that the remaining space between the second section and the skeleton changes, and it is difficult for the hook to be hung below the second section, thus making it inconvenient for the assembly of the relay. Summary of the Utility Model

The yoke includes a first section and a second section arranged vertically. The first section is connected to the iron core, the second section is located below the coil, one end of the hook is connected to the armature, and the other end of the hook is clamped in the second section. The skeleton is provided with support ribs for supporting the second section; a contact part, including a moving spring module and a static spring module, and the moving spring module can be closed or disconnected from the static spring module under the drive of the armature.
[0005] In some embodiments, two of the support ribs are separately arranged on the skeleton along the width direction of the armature.
[0006] In some embodiments, a guiding inclined surface for guiding the installation of the yoke is provided on the side of the support rib facing the coil.
[0007] In some embodiments, a first limiting structure is provided on the skeleton, and a second limiting structure is provided on the armature. The first limiting structure is used to cooperate with the second limiting structure to limit the movement space of the armature in the length direction and width direction of the armature.
[0008] In some embodiments, the first limiting structure is a groove, and the second limiting structure is a protrusion, and the protrusion is arranged in the groove.
[0009] In some embodiments, the protrusion and the groove wall are in clearance fit.
[0010] In some embodiments, along the width direction of the armature, protrusions are provided on both sides of the armature, and grooves are provided on both sides of the skeleton along the width direction of the armature, and one protrusion is arranged in one groove.
[0011] In some embodiments, along the height direction of the armature, the height range of the protrusion is 0.5 mm - 1.0 mm.
[0012] In summary, the horizontal relay provided by the present utility model has the following technical effects:
[0013] When installing the yoke iron and the iron core, the yoke iron is first placed on the support ribs, and the position of the yoke iron is defined by the support ribs. At this time, the yoke iron cannot rotate, and then the yoke iron and the iron core are riveted together, thus avoiding the situation that the installation channel of the hook between the yoke iron and the skeleton changes, resulting in difficulty in hanging the hook on the yoke iron, and facilitating the installation of the hook and the yoke iron.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.
[0026] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] Please refer to Figures 1 to 6, which is a schematic structural diagram of a horizontal relay 100, includes a base frame 30, a magnetic circuit driving part 10 and a contact part 20. The magnetic circuit driving part 10 and the contact part 20 are installed on the base frame 30. The magnetic circuit driving part 10 includes a bobbin 11, a coil 12, an iron core 13, a yoke 14, an armature 15, a hook 16 and a push rod 17. The bobbin 11 includes a cylindrical body 111 and a first mounting part 112 and a second mounting part 113 provided at both axial ends of the cylindrical body 111. When the relay is in use, the cylindrical body 111 is in an inverted state.
[0028] Among them, the iron core 13 is inserted into the cylindrical body 111, the coil 12 is wound around the outside of the cylindrical body 111, the moving contact module 21 and the static contact module 22 are located at one end of the bobbin 11 where the first mounting part 112 is provided, and the armature 15 is provided at one end of the second mounting part 113 of the bobbin 11.
[0029] Please refer to Figure 8 , the yoke 14 is L-shaped, including a first section 141 and a second section 142 arranged perpendicular to each other. The first section 141 is connected to the iron core 13. Specifically, it is used to be riveted to the iron core 13. The second section 142 extends axially towards the cylindrical body 111 and is located below the coil 12.
[0030] The hook 16 is generally L-shaped. One end is connected to the armature 15. Specifically, it is also connected to the armature 15 by riveting. One end is clamped on the second section 142 of the yoke 14. One end of the push rod 17 is installed on the armature 15, and the other end is installed on the moving contact module 21. Thus, when the coil 12 is energized, under the attractive force of the iron core 13, the armature 15 gradually attracts and closes with the iron core 13, thereby driving the push rod 17 to move. The movement of the push rod 17 drives the moving contact module 21 and the static contact module 22 to close; when the coil 12 is de-energized, the push rod 17 drives the moving contact module 21 and the static contact module 22 to separate.
[0031] Among them, please refer to Figure 8 , when connecting the first section 141 of the yoke 14 and the iron core 13, it is realized by spin riveting. During riveting, a rotating main shaft gradually approaches the iron core 13. When it contacts the iron core 13, it will give the iron core 13 a force in the rotating direction. The main shaft continues to advance, and the head of the iron core 13 begins to deform and is riveted to the yoke 14. At this time, the yoke 14 will also receive a force in the rotating direction. Before the riveting is finalized, the first section 141 of the yoke 14 will rotate by an angle, as Figure 8 shown. In this way, it causes the second section 142 to also rotate, thereby affecting the installation channel 1131 for the hook 16 between the second section 142 and the second mounting part 112. The hook 16 may be difficult to pass through the installation channel 1131 and be hung on the yoke 14; or there may be scratches between the two.
[0032] To solve the above problems, please refer to Figures 5 to 7, which is the horizontal relay 100 provided by the embodiment of the present utility model. When the horizontal relay 100 is set, by providing a support rib 114 on the skeleton 11, the support rib 114 is used to support the second section 142. In this way, when the yoke 14 and the iron core 13 are installed, the yoke 14 is first placed on the support rib 114, and the position of the yoke 14 is defined by the support rib 114. At this time, the yoke 14 cannot rotate. Then, the yoke 14 and the iron core 13 are riveted and connected, thus avoiding the situation that the installation channel 1131 of the hook 16 between the yoke 14 and the skeleton 11 changes, resulting in the difficulty of the hook 16 being hooked to the yoke 14, and facilitating the installation of the hook 16 and the yoke 14.
[0033] Specifically, the support rib 114 of this embodiment is provided on the bottom wall of the installation channel 1131. In other embodiments, it can be provided outside the installation channel 1131.
[0034] Among them, please refer to Figure 7 , in order to ensure the balance of the support for the hook 16, along the width direction of the armature 15, two support ribs 114 are separately provided on the skeleton 11. That is, when the yoke 14 is supported, both sides in the width direction of the yoke 14 can be supported. The gap between the two support ribs 114 is a part of the installation channel 1131 of the hook 16, so as to avoid the rotation of the yoke 14 when receiving the riveting force through the setting method of the two support ribs 114. For the convenience of description, the width direction of the armature 15 is defined as the left-right direction a, and the length direction of the armature 15 is defined as the up-down direction b.
[0035] Furthermore, in order to facilitate the insertion of the yoke 14 into the channel between the coil 12 and the support rib 114, a guiding inclined surface 115 for guiding the installation of the yoke 14 is provided on the side of the support rib 114 facing the coil 12, so as to guide the installation of the yoke 14 through the guiding inclined surface 115, and at the same time, the collision between the yoke 14 and the support rib 114 can also be reduced.
[0036] Please refer to Figure 5 and Figure 6 , the hook 16 includes a hanging part 161, a deformation arm 162 and a connecting part 163. A clamping block 164 is provided on the hanging part 161, and the clamping block 164 is used to be clamped in the clamping groove 143 of the yoke 14. The deformation arm 162 is used to undergo elastic deformation to drive the armature 15 to move when the coil 12 is energized or de-energized, and the connecting part 163 is used to be riveted to the iron core 13.
[0037] Among them, when the relay undergoes major impacts such as fading, the armature 15 generates an impact force on the hook 16 along the length direction of the armature 15, that is, along the up and down direction b. The impact force deforms the deformation arm 162, and in severe cases, even causes deformation, resulting in instability of the relay parameters in the later stage and affecting the use effect of the relay.
[0038] To solve the above problems, in an embodiment of the present utility model, a first limiting structure 116 is provided on the skeleton 11, and a second limiting structure 151 is provided on the armature 15. The first limiting structure 116 is used to cooperate with the second limiting structure 151 to limit the movement space along the length and width directions of the armature 15. Thus, when the relay drops, along the up and down direction b and the left and right direction a, the second limiting structure 151 and the first limiting structure 116 limit each other, avoiding excessive pressing of the hook 16 by the armature 15 and causing deformation of the hook 16.
[0039] Specifically, the above-mentioned first limiting structure 116 is provided on the second mounting portion 113.
[0040] Specifically, the first limiting structure 116 is a groove, and the second limiting structure 151 is a protrusion. The protrusion is arranged in the groove. When the armature 15 moves, the groove wall blocks the side wall of the protrusion, thereby avoiding excessive movement of the armature 15 along the up and down direction and the left and right direction and causing deformation of the hook 16; further, by setting a protrusion on the armature 15, the suction force between the armature 15 and the iron core 13 can be increased. In other embodiments, it is also possible to set a groove on the skeleton 11 and a protrusion on the armature 15, which can also achieve the limiting effect between the two.
[0041] Further, since the armature 15 needs to rotate, in order to avoid the influence of the groove setting on the movement of the armature 15, the protrusion and the groove wall are in clearance fit, so that the groove wall does not affect the rotational freedom of the movement of the armature 15, and only limits the armature 15 along the up and down direction b and the left and right direction a.
[0042] Among them, along the height direction of the armature 15, the height range of the protrusion is 0.5 mm - 1.0 mm, so that the protrusion can have a certain height to ensure the structural strength of the protrusion. Thus, when the armature 15 moves, the cooperation force between the protrusion and the groove wall is ensured; further, the setting of this thickness size can make the height of the protrusion relatively high, which is convenient for molding and also convenient for the installation between the armature 15 and the skeleton 11.
[0043] Understandably, in order to ensure the limiting effect of the skeleton 11 on the armature 15, on both sides of the armature 15 in the width direction, that is, along the left-right direction a, there are protrusions provided, and on both sides of the skeleton 11 along the left-right direction of the armature 15, there are grooves provided. One protrusion is arranged in one groove. In this way, when the armature 15 moves in the up-down direction, the groove wall of one groove limits one protrusion, further increasing the limiting effect on the armature 15.
[0044] For the above-mentioned horizontal relay 100, by providing the support ribs 114 on the skeleton 11 to support the yoke 14, it is avoided that the yoke 14 rotates when the yoke 14 and the iron core 13 are riveted, which affects the subsequent installation of the hook 16 and the yoke 14; by providing grooves on the skeleton 11 and protrusions on the armature 15, the groove walls and the protrusions cooperate to limit the movement of the armature 15 in the up-down direction, avoiding the deformation of the hook 16 caused by the excessive movement of the armature 15.
[0045] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
