Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a relay. Background Technology

[0002] A relay is an automatic switching element that uses electromagnetic force to drive mechanical parts. It generally includes a magnetic circuit, a driving part, a moving contact group, and a stationary contact group.

[0003] The magnetic circuit includes a coil assembly, a yoke assembly, and an armature assembly. The coil assembly typically includes a coil winding, an iron core, and two yokes. The iron core is placed inside the coil winding, and the two yokes are fixed to both ends of the iron core. The ends of the two yokes furthest from the iron core form two magnetic drive ends. The separation or engagement of the armature assembly and the different ends of the two yokes drives the pushing part to perform linear motion, thereby driving the linear motion of the moving contact assembly mounted on the pushing part.

[0004] When the moving contact group is installed on the push card, it is achieved by the elastic card arranged in an I-shape being snapped onto the push card. The push card has two ends along its own height direction with card blocks that engage with the elastic card. Therefore, when the elastic card is snapped onto the card block, it needs to be driven to deform, which makes it inconvenient to install the moving contact group. Utility Model Content

[0005] To address at least one problem existing in the prior art, according to one aspect of the present invention, a relay is provided, comprising:

[0006] case;

[0007] The magnetic drive section, located within the housing, includes a coil assembly, a yoke assembly, and an armature assembly, wherein the axial direction of the coil assembly is defined as the X direction.

[0008] The contact portion includes a moving contact group and a stationary contact group that can be disconnected or attracted to each other along the X direction, wherein the stationary contact group is mounted on the housing;

[0009] The pushing part includes a pushing card and a locking member. One end of the pushing card is equipped with the armature assembly, and the locking member is used to install the moving contact group. The other end of the pushing card is provided with a slot.

[0011] In some embodiments, the latching block includes an extension section and a latching section arranged perpendicularly to each other. The extension section is connected to the body and extends toward the side opposite to the moving contact group and toward the X direction, while the latching section extends along the Y direction and toward the direction away from the body.

[0012] The slot includes a first locking part and a second locking part that are interconnected. The first locking part is used to accommodate the locking segment, and the second locking part is used to allow the extension segment to pass through.

[0013] In some embodiments, the groove wall of the first locking part 1 facing the moving contact group has a notch, and the notch is connected to the first locking part and the second locking part respectively.

[0014] In some embodiments, the snap-fit ​​bracket further includes a plug-in block disposed on the main body, and the blocking bracket is provided with a plug-in slot, into which the plug-in block is inserted.

[0015] In some embodiments, the moving contact module includes at least two overcurrent bridges, two moving contacts disposed on each of the overcurrent bridges, and at least two springs. The at least two overcurrent bridges are arranged along the Z direction, and each spring is connected to one of the overcurrent bridges. Each spring is connected to the snap-fit ​​component.

[0016] In some embodiments, the spring and the snap-fit ​​are riveted together.

[0017] In some embodiments, the spring includes a first connecting portion, a deformable portion, and a second connecting portion. The first connecting portion extends in the Y direction and is used to connect with the snap-fit ​​bracket. The deformable portion is formed by bending the end of the first connecting portion toward the flow bridge. The second connecting portion is arranged parallel to the first connecting portion and is not collinear, and is used to connect with the flow bridge.

[0018] In some embodiments, at least one pair of limiting posts is provided on the inner wall of the housing, and the two limiting posts in each pair of limiting posts are separated along the Y direction and located on opposite sides of the push card. The push card is slidably disposed relative to the limiting posts, and multiple pairs of limiting posts are separated along the X direction.

[0019] In some embodiments, the relay further includes a guide rod and an energy storage spring, the guide rod extending in the X direction and connected to one of the housing or the push clip, and slidably disposed relative to the other, the energy storage spring and the guide rod being spaced apart in the Y direction and connected to the housing, for elastic deformation under the drive of the moving contact group, so as to apply an elastic force when the moving contact group moves in the direction of the stationary contact group.

[0020] In summary, the relay provided by this utility model has the following technical effects:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] Please see Figures 1 to 12 The relay 100 provided in this embodiment of the present utility model includes a housing 10, a magnetic drive part 20, a contact part 30, and a push part 40.

[0041] Please refer to Figures 6 to 12 The housing 10 is used to install the magnetic drive system 20, the contact part 30, and the pushing part 40. The magnetic drive part 20 is located inside the housing 10 and includes a coil assembly 21, a yoke assembly 22, and an armature assembly 23. The axial direction of the coil assembly 21 is defined as the x-direction. The contact part 30 includes a moving contact group 32 and a stationary contact group 31 that can be disconnected or attracted to each other along the x-direction. The stationary contact group 31 is installed in the housing 10. The pushing part 40 includes a pushing card 41 and a locking member 42. One end of the pushing card 41 is equipped with the armature assembly 23. The locking member 42 is used to install the moving contact group 32. The other end of the pushing card 41 is provided with a slot 413. The extension direction of the slot 413 is defined as the Z-direction. One end of the slot 413 extends to the edge of the slot 413. The locking member 42 is locked in the slot 413.

[0042] The aforementioned relay 100 uses the housing 10 as a mounting base, with the magnetic drive part 20 providing the driving force. The axial direction of the coil assembly 21 in the magnetic drive part 20 is the X direction. The direction of opening or closing of the moving contact group 32 and the stationary contact group 31 in the contact part 30 is the X direction. When installing the moving contact group 32, the push card 41 and the carding member 42 in the push part 40 have a card groove 413 extending in the Z direction on the push card 41, and the card groove 413 extends to the edge of the push card 41. Thus, when the moving contact group 32 is installed on the push card 41 by the carding member 42, the carding member 42 slides along the edge of the push card 41 and into the card groove 413 in the Z direction. The moving contact group 32 can be installed quickly without the need for external force to drive the carding member 42 to deform, thus facilitating the installation of the moving contact group 32.

[0043] Please refer to Figures 1 to 4 The housing 10 of this embodiment includes a detachably connected bottom shell 11 and a top cover 12. The bottom shell 11 is equipped with a magnetic drive system 20, a contact portion 30, and a pushing portion 40. The top cover 12 is placed on top of the bottom shell 11 along the Z direction to seal the installation space inside the bottom shell 11.

[0044] Please refer to Figure 2 , Figure 7 and Figure 8The coil assembly 21 includes a frame 211, a coil 212 wound around the frame 211, and an iron core 213 inserted into the frame 211. The yoke assembly 22 includes two pairs of yokes 221, each yoke 221 being located at one end of the axial direction of the coil 212 and fixed to the iron core 213, and each yoke 221 protruding relative to the coil 212 to have a driving end. The armature assembly 23 includes two spaced armatures 231 and a permanent magnet 232 sandwiched between the two armatures 231, each armature 231 being U-shaped, and one armature 231 surrounding the other armature 231, so that when the coil 212 is energized, the two armatures 231 and the two yokes 221 can be alternately disconnected or attracted, so as to realize the disconnection or attraction between the moving contact group 32 and the stationary contact group 31.

[0045] Please refer to Figure 4 and Figure 5 The push card 41 includes a push part 411 and a mounting part 412 arranged perpendicular to the push part 411. During the alternating engagement of the armature 231 and the yoke 221 in the X direction, the push part 411 will move in the X direction. In order to ensure the stability of the push card 41 driving the contact group 32 in the X direction, at least one pair of limiting posts 13 is provided on the inner wall of the housing 10. Two of the limiting posts 13 in each pair of limiting posts 13 are separated in the Y direction and are located on opposite sides of the push part 411 of the push card 41. The push part 411 is slidably arranged relative to the limiting posts 13. Multiple pairs of limiting posts 13 are separated in the X direction so as to limit the movement of the push part 411 in the X direction by setting the limiting posts 13, thereby ensuring the stability of the movement of the push card 41 in the X direction.

[0046] In this embodiment, since the bottom shell 11 is equipped with the aforementioned drive system, contact portion 30, and pushing portion 40, when the limiting post 13 is set, the limiting post 13 is set on the bottom shell 11, thereby making it easy to determine the setting position of the limiting post 13 according to the installation position of the pushing portion 411; in other embodiments, the limiting post 13 can also be set on the top cover 12 and extend toward the bottom shell 11, which can also achieve the limiting effect on the pushing portion 411.

[0047] Specifically, in this embodiment, a pair of limiting posts 13 are provided, which not only ensures the limiting of the pushing part 411, but also reduces the molding difficulty of the limiting posts 13 and reduces costs.

[0048] Please see Figures 2 to 4 as well as Figures 6 to 10In one embodiment of the present invention, the pushing part 411 extends along the X direction and the mounting part 412 extends along the Y direction. The pushing part 411 is used to mount the armature 231, and the mounting part 412 is provided with the above-mentioned slot 413 for mounting the moving contact group 32. Thus, when the two armatures 231 move along the X direction, they can drive the moving contact group 32 and the stationary contact group 31 to close or open with each other.

[0049] Please refer to Figure 7 , Figure 8 , Figures 10 to 11 When the snap-fit ​​component 42 and the mounting part 412 are installed, the snap-fit ​​component 42 includes a snap-fit ​​bracket 421 and a blocking bracket 422 that are detachably connected. The moving contact group 32 is disposed between the snap-fit ​​bracket 421 and the blocking bracket 422. The snap-fit ​​bracket 421 includes a main body 4211 and a snap-fit ​​block 4212 disposed on the main body 4211. The main body 4211 is connected to the moving contact group 32. The snap-fit ​​block 4212 is used to snap into the slot 413. Thus, by setting the snap-fit ​​component 42 to be detachably connected to the snap-fit ​​bracket 421 and the blocking bracket 422, when installing the moving contact group 32, the moving contact group 32 can be connected to the snap-fit ​​bracket 421, and then the blocking bracket 422 and the snap-fit ​​bracket 421 can be installed. After the snap-fit ​​bracket 421 is snapped into the mounting part 412, the installation of the moving contact group 32 can be realized. Furthermore, the magnetic conductor 323 on the moving contact assembly 32 can be installed by setting the blocking bracket 422.

[0050] Specifically, when engaging via the engaging block 4212 and the push card 41, the engaging block 4212 includes an extension section 4213 and an engaging section 4214 arranged perpendicularly. The extension section 4213 is connected to the main body 4211 and extends in the X direction away from the moving contact group 32. The engaging section 4214 extends in the Y direction away from the main body 4211. Correspondingly, the card slot 413 includes a first engaging portion 4131 and a second engaging portion 4132 that are interconnected. The first engaging portion 4131 is used to receive the engaging section 4214, and the second engaging portion 4132 is used for the extension section 4213 to pass through. Thus, when the engaging block 4212 is engaged in the card slot 413, the extension section 4213 passes through the second engaging portion 4132. For example... Figure 6 As shown, the entire snap-fit ​​block 4212 is snapped into the slot 413 by the cooperation of the snap-fit ​​section 4214 and the slot wall of the slot 413.

[0051] Further, please refer to Figure 10In order to facilitate the insertion of the locking segment 4214 into the first locking part 4131, the groove wall of the first locking part 4131 facing the moving contact group 32 is provided with a notch 4133. The notch 4133 is connected to the first locking part 4131 and the second locking part 4132 respectively, so that when the locking block 4212 is locked in through the notch 4133, the locking segment 4214 can quickly lock into the first locking part 4131 through the notch 4133.

[0052] Understandably, in order to ensure the stability of the moving contact group 32 installed on the push card 41 by the snap-fit ​​component 42, a snap-fit ​​block 4212 is provided on each of the opposite sides of the main body 4211 along the Y direction. The two snap-fit ​​blocks and the two slots 413 on the push card 41 are snapped together to ensure the installation stability of the moving contact group 32.

[0053] Please refer to Figure 12 When the snap-fit ​​bracket 421 and the blocking bracket 422 are detachably installed, the snap-fit ​​bracket 421 is provided with a plug-in block 4215 and the blocking bracket 422 is provided with a plug-in groove 4221. The plug-in block 4215 is inserted into the plug-in groove 4221. In this way, the detachable installation between the snap-fit ​​bracket 421 and the blocking bracket 422 can be quickly achieved by inserting and pulling the plug-in block 4215 into the plug-in groove 4221.

[0054] Please see Figures 7 to 9 , Figure 11 as well as Figure 12 This is a schematic diagram of the moving contact assembly 32 according to an embodiment of the present invention. The moving contact 322 module includes at least two current bridges 321, two moving contacts 322 disposed on each current bridge 321, and at least two spring contacts 33. The at least two current bridges 321 are arranged along the Z direction, and one spring contact 33 is connected to one current bridge 321. Each spring contact 33 is connected to a snap-fit ​​member 42. That is, the two moving contacts 322 are respectively disposed at one end of the current bridge 321 along the Y direction, and the current flows from one of the moving contacts 321. 2. The flow moves towards another moving contact 322. The spring 33 is used to store energy when the moving contact 322 and the stationary contact in the stationary contact group 31 are closed, and to release energy when the moving contact 322 and the stationary contact are disconnected. By setting one spring 33 for each flow bridge 321, compared to the method of connecting multiple flow bridges 321 through an elastic sheet, the structure of each spring 33 in this embodiment is simpler and easier to form, and it is also convenient to install with the corresponding flow bridge 321.

[0055] Specifically, the moving contact group 32 in this embodiment includes two overcurrent bridges 321 and two springs 33, with one overcurrent bridge 321 connected to one spring 33.

[0056] Furthermore, the moving contact assembly 32 in this embodiment also includes at least two magnetic conductors 323, each corresponding to a current-carrying bridge 321, with the magnetic conductor 323 mounted on the current-carrying bridge 321 and passing through the blocking bracket 422. It can be understood that the moving contact assembly 32 in this embodiment includes two current-carrying bridges 321, which also includes two magnetic conductors 323.

[0057] In this embodiment, the magnetic conductor 323 is mounted on the current bridge 321, and the moving contact 322 is also mounted on the current bridge 321. The spring piece 33 is connected to the side of the current bridge 321 away from the side where the moving contact 322 is mounted. The moving contact group 32 can be installed by mounting the spring piece 33 on the snap-fit ​​bracket 421. Therefore, in order to ensure the installation stability of the moving contact group 32, the spring piece 33 and the snap-fit ​​bracket 421 in the snap-fit ​​component 42 are riveted together to achieve stable installation of the entire moving contact group 32 on the snap-fit ​​component 42.

[0058] Specifically, please refer to Figure 12 In this embodiment, when the spring piece 33 is connected to the mounting bracket 421 and the overcurrent bridge 321 respectively, the spring piece 33 includes a first connecting part 331, a deformable part 332, and a second connecting part 333. The first connecting part 331 extends in the Y direction and is used to connect with the mounting bracket 421. The deformable part 332 is formed by bending the end of the first connecting part 331 towards the overcurrent bridge 321. The second connecting part 333 is arranged parallel to the first connecting part 331 and is not collinear, and is used to connect with the overcurrent bridge 321. It can be understood that the deformable part 332 in this embodiment is used to store energy and release energy after deformation. The two non-parallel first connecting parts 331 and second connecting parts 333 respectively realize the installation with the mounting bracket 421 and the overcurrent bridge 321.

[0059] Understandably, corresponding to the number of moving contacts 322, the same number of stationary contacts are also provided in the stationary contact group 31.

[0060] Please see Figure 2 , Figure 7 as well as Figure 8 Since multiple moving contact groups 32 are installed on the mounting part 412 of the push card 41, the mounting part 412 has a certain extension length in the Y direction. In order to ensure the stability of the moving contact group 32 when it moves in the X direction, guide rods 50 are provided at both ends of the mounting part 412 in the Y direction to guide the movement of the mounting part 412 in the X direction. An energy storage spring 60 is also provided so that it is compressed and undergoes elastic deformation to store energy when the moving contact group 32 moves away from the stationary group 31, and can recover its deformation and release energy when the moving contact group 32 moves closer to the stationary group 31.

[0061] Specifically, to minimize the size of the entire relay 100 in this embodiment, the guide rod 50 extends in the X direction and connects to either the housing 10 or the pusher 41, while sliding relative to the other. The energy storage spring 60 and the guide rod 50 are separated in the Y direction and connected to the housing 10. The guide rod 50 is used to undergo elastic deformation under the drive of the moving contact group 32, so that it can apply an elastic force when the moving contact group 32 moves towards the stationary contact group 31. In other words, when the guide rod 50 is in place, it can connect to the housing 10, but it needs to be connected to the pusher 41. The sliding arrangement of the moving card 41 or the guide rod 50 connected to the pushing card 41 and slidably arranged relative to the housing 10 can both achieve the effect of guiding the movement of the moving contact group 32. By separating the energy storage spring 60 and the guide rod 50 along the Y direction, the energy storage spring 60 can avoid the support block that supports the guide rod 50, and the energy storage spring 60 can utilize other spaces on the bottom housing 11 to reduce the length of the entire relay 100 housing 10 along the X direction, while adapting to the arrangement of the coil assembly 21 along the X direction.

[0062] Specifically, the mounting part 412 is provided with a through hole 4134 for the guide rod 50 to pass through.

[0063] In this embodiment, the push card 41 is provided with 3 moving contact groups 32 and 3 stationary contact groups. In other embodiments, 1, 2 or other numbers of moving contact groups 32 can be provided as needed.

[0064] In this embodiment, the relay 100 also includes a current transformer 70 connected to the load terminal 311 of the stationary contact group 31.

[0065] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
