Description

Technical Field

[0001] This utility model relates to the field of solid-state relay technology, specifically to a solid-state relay with protection function. Background Technology

[0002] When a solid-state relay is installed in a relay socket, vibrations caused by the operation of other electrical components may affect the tightness of the connection between the solid-state relay and the relay socket. In particular, electrical components such as high-power circuit breakers generally vibrate more when they are opening and closing, which may cause the pins on the solid-state relay to become loose in the socket holes, thus affecting the use of the solid-state relay.

[0003] Chinese patent CN218730657U discloses a solid-state relay with protection function. This solid-state relay with protection function is fixed by snapping a snap plate into a slot, realizing the effective connection and fixation of the relay socket and the solid-state relay. Through the cooperation of spring and guide rod, the vibration force from the relay socket or mounting base can be absorbed and buffered, realizing the shock absorption protection function of the solid-state relay and realizing the stable connection between the solid-state relay and the load circuit.

[0004] The aforementioned solid-state relays with protective functions can only buffer vertical vibrations, and since the direction of vibration is not fixed, their damping effect on non-vertical vibrations is poor, resulting in unsatisfactory protection. Utility Model Content

[0005] The purpose of this invention is to provide a solid-state relay with protection functions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid-state relay with protection function, including a solid-state relay and a relay socket, wherein a shock-absorbing mechanism is provided between the solid-state relay and the relay socket;

[0007] The shock absorption mechanism includes a mounting plate, an outer rubber pad, and an inner rubber pad. The top of the mounting plate has an insertion hole. The mounting plate is movably mounted inside the relay socket. Eight rubber pillars are fixedly mounted on the bottom of the mounting plate in a circumferential array. The bottom ends of the rubber pillars are fixedly connected to the inner wall of the bottom of the relay socket. The rubber pillars are inclined. A connecting component is provided on the top of the mounting plate. The outer rubber pad is fixedly mounted on the inner wall of the relay socket. The inner rubber pad is fixedly fitted around the perimeter of the mounting plate. A gap is left between the outer and inner rubber pads. The upper surface of the relay socket is higher than the upper surface of the mounting plate.

[0008] Furthermore, the connecting component includes a slot and an elastic sheet. The slot is formed on the outer wall of the solid-state relay, and the elastic sheet is fixedly installed on the top of the mounting plate. A retaining plate is fixedly installed on the outer wall of the elastic sheet facing the solid-state relay, and the retaining plate is inserted into the slot.

[0009] Furthermore, the inner wall of the slot is fixedly installed with raised dots, and the outer wall of the card plate facing the solid-state relay has a circular groove corresponding to the raised dots. The upper and lower surfaces of the card plate are both inclined surfaces. A top block is provided below the slot. The top block is fixedly installed on the outer wall of the solid-state relay. The upper and lower surfaces of the top block are both inclined surfaces.

[0010] Furthermore, the bottom of the relay socket is provided with heat dissipation holes, and the top of the relay socket is fixedly installed with a top cover. The inner side of the top cover is provided with a clearance groove, which is directly opposite the connecting component. A gap is left between the inner side of the top cover and the mounting plate.

[0011] Furthermore, a second connecting plate is fixedly installed on the outer wall of the relay socket. Four second connecting plates are provided and are located at the four corners of the relay socket. A first connecting plate is fixedly installed on the bottom of the second connecting plate, and one end of the first connecting plate extends into the bottom of the relay socket.

[0012] Furthermore, the top of the connecting plate is provided with a threaded hole, and a rubber ring is fixedly installed on the bottom of the connecting plate. There are two threaded holes and two rubber rings on the same connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Eight inclined rubber columns are set to support the mounting plate. The solid-state relay is fixedly connected to the mounting plate through connecting components. After the vibration is transmitted from the solid-state relay to the mounting plate, the mounting plate will move in a certain direction according to the vibration. At this time, the rubber columns will be pulled to deform. The rubber columns themselves have a shock absorption effect, so they can reduce the vibration of the mounting plate. Because the rubber columns can deform in different directions, they can reduce vibration in different directions.

[0015] 2. The outer and inner rubber pads are designed to prevent collisions between the mounting plate and the inner wall of the relay socket when there is a large vibration. At the same time, when the mounting plate moves and causes the inner rubber pad to move and squeeze the outer rubber pad, the vibration on the mounting plate can be reduced by the shock absorption effect of the outer and inner rubber pads themselves.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a solid-state relay with protection function, including a solid-state relay 1 and a relay socket 2, with a shock-absorbing mechanism 3 provided between the solid-state relay 1 and the relay socket 2;

[0024] The shock absorption mechanism 3 includes a mounting plate 301, an outer rubber pad 304, and an inner rubber pad 305. The top of the mounting plate 301 has an insertion hole. The mounting plate 301 is movably mounted inside the relay socket 2. Eight rubber pillars 303 are fixedly mounted on the bottom of the mounting plate 301 in a circumferential array. The bottom ends of the rubber pillars 303 are fixedly connected to the inner wall of the bottom of the relay socket 2. The rubber pillars 303 are inclined. A connecting component 302 is provided on the top of the mounting plate 301. The outer rubber pad 304 is fixedly mounted on the inner wall of the relay socket 2. The inner rubber pad 305 is fixedly fitted around the perimeter of the mounting plate 301. A gap is left between the outer rubber pad 304 and the inner rubber pad 305. The upper surface of the relay socket 2 is higher than the upper surface of the mounting plate 301. The eight inclined rubber pillars 303 provide shock absorption for the mounting plate 301. The solid-state relay 1 is fixedly connected to the mounting plate 301 via the connecting component 302. After vibration is transmitted from the solid-state relay 1 to the mounting plate 301, the mounting plate 301 will move in a certain direction according to the vibration. At this time, the rubber column 303 will be deformed. The rubber column 303 itself has a shock-absorbing effect, so it can reduce the vibration of the mounting plate 301. Because the rubber column 303 can deform in different directions, it can reduce vibration in different directions. The outer rubber pad 304 and the inner rubber pad 305 are set to prevent the mounting plate 301 from colliding with the inner wall of the relay socket 2 when the vibration amplitude is large. At the same time, when the mounting plate 301 moves and drives the inner rubber pad 305 to move and squeeze the outer rubber pad 304, the shock-absorbing effect of the outer rubber pad 304 and the inner rubber pad 305 can be used to reduce the vibration on the mounting plate 301.

[0025] The connecting component 302 includes a slot 3021 and an elastic piece 3022. The slot 3021 is formed on the outer wall of the solid-state relay 1. The elastic piece 3022 is fixedly installed on the top of the mounting plate 301. A card 3023 is fixedly installed on the outer wall of the elastic piece 3022 facing the solid-state relay 1. The card 3023 is inserted into the slot 3021. The solid-state relay 1 is installed by inserting the card 3023 into the slot 3021. The installation is simple and quick. The elastic piece 3022 acts as an elastic element to allow the card 3023 to be inserted into and removed from the slot 3021.

[0026] The inner wall of the slot 3021 is fixedly equipped with a raised dot 7. The outer wall of the card plate 3023 facing the solid-state relay 1 is provided with a circular groove corresponding to the raised dot 7. The raised dot 7 and the corresponding circular groove are provided to strengthen the connection between the card plate 3023 and the slot 3021. The upper and lower surfaces of the card plate 3023 are inclined surfaces. A top block 8 is provided below the slot 3021. The top block 8 is fixedly installed on the outer wall of the solid-state relay 1. The upper and lower surfaces of the top block 8 are inclined surfaces. The top block 8 is provided to push the card plate 3023 during the downward movement of the solid-state relay 1, so that the card plate 3023 pushes the elastic sheet 3022, so that the elastic sheet 3022 deforms, and the card plate 3023 can be better inserted into the slot 3021.

[0027] The relay socket 2 has a heat dissipation hole 5 at the bottom and a top cover 4 fixedly installed on the top of the relay socket 2. The inner side of the top cover 4 has a clearance groove 6, which is directly opposite the connecting part 302. There is a gap between the inner side of the top cover 4 and the mounting plate 301. The heat dissipation hole 5 is provided to dissipate heat from the inside of the relay socket 2. The top cover 4 is provided to cover the top of the relay socket 2, making the overall appearance more aesthetically pleasing.

[0028] A second connecting plate 10 is fixedly installed on the outer wall of the relay socket 2. There are four connecting plates 10, which are located at the four corners of the relay socket 2. A first connecting plate 9 is fixedly installed on the bottom of the second connecting plate 10. One end of the first connecting plate 9 extends into the bottom of the relay socket 2. The first connecting plate 9 is connected to the relay socket 2 through the second connecting plate 10. The first connecting plate 9 supports the relay socket 2, so that the heat dissipation hole 5 at the bottom of the relay socket 2 will not be blocked by the placement surface.

[0029] The top of the connecting plate 9 is provided with a threaded hole 11, and the bottom of the connecting plate 9 is fixedly installed with a rubber ring 12. There are two threaded holes 11 and two rubber rings 12 on the same connecting plate 9. The threaded hole 11 is used to fix the connecting plate 9 to the installation position, and the rubber ring 12 is used to form shock absorption between the connecting plate 9 and the installation position.

[0030] Working principle: In use, the solid-state relay 1 is placed from top to bottom, causing the top block 8 on the solid-state relay 1 to push the retaining plate 3023, which in turn deforms the elastic sheet 3022. After the retaining plate 3023 and the top block 8 are misaligned, the elastic sheet 3022 resets, causing the retaining plate 3023 to move and engage with the retaining slot 3021, completing the installation of the solid-state relay 1. At the same time, the pins of the solid-state relay 1 are inserted into the sockets. After the vibration is transmitted from the solid-state relay 1 to the mounting plate 301, the mounting plate 301 will move in a certain direction according to the vibration, which will pull the rubber column 303 to deform. The rubber column 303 itself has a shock-absorbing effect, thus achieving shock absorption of the mounting plate 301. Because the rubber column 303 can deform in different directions, it can absorb vibrations in different directions. The outer rubber pad 304 and the inner rubber pad 305 are set to prevent the mounting plate 301 from colliding with the inner wall of the relay socket 2 when the vibration amplitude is large. At the same time, when the mounting plate 301 moves and drives the inner rubber pad 305 to move and squeeze the outer rubber pad 304, the shock-absorbing effect of the outer rubber pad 304 and the inner rubber pad 305 can be used to absorb the vibration on the mounting plate 301.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
