Description

Technical Field

[0001] This application relates to the field of relays, and in particular to a relay. Background Technology

[0002] A relay is an electronic component mainly used to implement automatic control and protection functions in circuits. It typically consists of an electromagnet and a set of contacts. When the relay coil is energized, the electromagnet generates magnetic force, attracting the contacts and thus connecting or disconnecting the circuit. The relay contacts can be normally open or normally closed. Normally open contacts are open when not energized and close when energized.

[0003] A relay consists of a coil, armature, contacts, yoke, and housing. A snap-fit ​​block and a spring snap-fit ​​block are fixed to the back of the relay housing. The relay is typically installed in a relay box, which usually contains a support plate for mounting the relay. During installation, the installer pulls up the spring snap-fit ​​block, allowing it and the snap-fit ​​block to pass through the top and bottom of the support plate. The relay then contacts the support plate. After releasing the spring snap-fit ​​block, it locks into place on the support plate in the relay box, thus supporting the relay.

[0004] During the installation of the fixed relay, when the spring clip is released, the spring clip quickly snaps onto the strip plate under the action of the spring. At the same time, the spring clip abuts against the strip plate, causing the retaining block to also abut against the strip plate. During this process, the spring clip and retaining block will be subjected to a large instantaneous impact from the spring, which may affect their service life. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that when the spring-loaded locking block is released, the spring-loaded locking block and the locking block will be subjected to a large instantaneous impact by the spring, which may affect the service life of the spring-loaded locking block and the locking block. This application provides a relay.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A relay includes a relay body, with a plurality of connection contacts installed at both ends of the relay body. The relay body has a plurality of connection sockets. Two symmetrical abutment blocks are disposed on the side of the relay body away from the connection contacts, with the two abutment blocks located at one end of the relay body. Two symmetrical locking blocks are disposed on one side of the two abutment blocks, and the locking blocks are fixedly connected to the relay body. A locking mechanism is disposed at the end of the relay body away from the locking blocks. A heat dissipation mechanism is disposed on the relay body.

[0008] By adopting the above technical solution, the locking block is fastened to the bottom of the strip plate of the relay box, and the contact block is tightly pressed against it. Then, the installer directly pulls the locking mechanism to extend it from the relay body and lock it above the strip plate in the relay box. The locking mechanism and the locking block fix the relay body, thereby ensuring that the relay body can be stably fixed in the relay box. This reduces the possibility of instantaneous impact on the locking block, which could lead to a reduction in service life, when using traditional spring clips for fixing.

[0009] Furthermore, the latching mechanism includes a latching plate disposed on the relay body, with sliding blocks fixed at both ends of the latching plate. A sliding groove is provided on the relay body, and the sliding blocks are located in the sliding groove and slidably connected to the relay body. A movement limiting component is provided between the latching plate and the relay body.

[0010] By adopting the above technical solution, the sliding block is moved by the moving limit component, and the sliding block causes the snap-fit ​​plate to extend from the relay body. The snap-fit ​​plate and snap-fit ​​block fix the relay body, which facilitates the installation of the relay body. At the same time, it can reduce the possibility of instantaneous impact on the snap-fit ​​block when the transmission is installed using spring clips, which may affect the service life.

[0011] Furthermore, the moving limit assembly includes two moving blocks symmetrically arranged on both sides of the relay body. A metal wire is provided between the moving block and the sliding block. The metal wire passes through the relay body, and both ends of the metal wire are fixedly connected to the moving block and the sliding block.

[0012] By adopting the above technical solution, the moving block drives the metal wire, and when the metal wire drives the sliding block, the sliding block can easily drive the snap-on plate to extend out of the relay body.

[0013] Furthermore, support blocks are fixed on both sides of the relay body, and a fixed block 1 is slidably connected to the support block. The fixed block 1 is fixedly connected to the moving block. Two symmetrical fixed blocks 2 are slidably connected to the support block. The snap-fit ​​block abuts against the fixed blocks 2. Snap-fit ​​teeth are provided on both the fixed blocks 1 and 2, and they face opposite directions.

[0014] By adopting the above technical solution, the moving block moves on the support block under the support of the fixed block one. When the fixed block one stops, the fixed block two restricts the fixed block one, so that the snap-fit ​​plate can be kept in the extended state.

[0015] Furthermore, a snap-fit ​​spring is provided between the second fixing block and the support block, and both ends of the snap-fit ​​spring are fixedly connected to the second fixing block and the support block.

[0016] By adopting the above technical solution, the locking spring pushes the second fixing block, so that the locking teeth on the second fixing block can lock into the locking teeth on the first fixing block, thereby making it easy for the second fixing block to lock into the first fixing block.

[0017] Furthermore, a support spring is provided inside the sliding groove, and both ends of the support spring are fixedly connected to the sliding block and the relay body.

[0018] By adopting the above technical solution, the sliding block is supported by a support spring, which allows the sliding block to drive the snap-fit ​​plate into the relay body, reducing the obstruction of installation by the snap-fit ​​plate protruding during installation.

[0019] Furthermore, the heat dissipation mechanism includes a first thermally conductive copper sheet fixed on the side of the relay body away from the connection contact point, a third thermally conductive copper sheet disposed on the first thermally conductive copper sheet, and a second thermally conductive copper sheet fixed between the first thermally conductive copper sheet and the third thermally conductive copper sheet.

[0020] By adopting the above technical solution, the heat generated by the relay body is transferred to the first heat-conducting copper sheet, which in turn transfers the heat to the second and third heat-conducting copper sheets, and then the heat is transferred to the air. This reduces the possibility that the relay body may be affected by high temperature and thus affect normal operation.

[0021] Furthermore, the second heat-conducting copper sheet is wavy.

[0022] By adopting the above technical solution, the heat-conducting copper sheet is wavy, which increases the contact area with the air and improves the efficiency of transferring the heat absorbed by the heat-conducting copper sheet into the air.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application, during the installation of the relay body, first places the side of the relay body with the locking block against the strip plate inside the relay box, allowing the locking block to be secured to the bottom of the strip plate under the contact of the contact block. Then, the entire relay body rests against the strip plate. The installer then pulls and moves the moving block, which slides on the support block under the support of the first fixed block. When the moving block moves, it drives the metal wire, which in turn drives the sliding block. As the sliding block moves in the sliding groove, it compresses the support spring. When the sliding block moves, it drives the locking plate, which then locks onto the back of the strip plate. The locking plate and locking block secure the relay body to the strip plate of the relay box. Then, under the push of the locking spring, the second fixed block locks onto the first fixed block, limiting the movement of the first fixed block and keeping the locking plate extended. This achieves the purpose of facilitating the installation of the relay body and reducing the possibility of momentary impact on the locking block during installation using spring clips, which could affect the service life.

[0025] 2. In this application, when the relay body is in normal use, the heat generated by the relay body is transferred to the first heat-conducting copper sheet, which in turn transfers the heat to the second heat-conducting copper sheet. The second heat-conducting copper sheet is wavy, which increases the contact area with the air, allowing the heat absorbed by the second heat-conducting copper sheet to be transferred into the air. At the same time, the third heat-conducting copper sheet further assists in heat dissipation. This also makes the surface of the relay body flat, reducing the possibility of the relay body shifting due to the wavy shape of the second heat-conducting copper sheet during installation. This achieves the purpose of reducing the possibility of the relay body being affected by high temperature during normal operation. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0034] This application discloses a relay.

[0035] Reference Figure 1 , Figure 2 and Figure 3A relay includes a relay body 1, with several connecting contacts 2 installed at both ends of the relay body 1. Several connection sockets 3 are provided on the relay body 1. Two symmetrical abutment blocks 4 are provided on the side of the relay body 1 away from the connecting contacts 2. The two abutment blocks 4 are located at one end of the relay body 1. Two symmetrical locking blocks 5 are provided on one side of the two abutment blocks 4. The locking blocks 5 are fixedly connected to the relay body 1. A locking mechanism 6 is provided on the end of the relay body 1 away from the locking blocks 5. A heat dissipation mechanism 7 is provided on the relay body 1.

[0036] When installing the relay body 1, the side of the relay body 1 with the contact block 4 and the snap-fit ​​block 5 is directly placed into the relay box specifically for installing relays. The relay body 1 is placed against the strip plate of the external relay box, and the snap-fit ​​block 5 is fastened to the bottom of the strip plate. The contact block 4 is then firmly engaged. The installer then pulls the snap-fit ​​mechanism 6, allowing it to extend from the relay body 1 and snap onto the strip plate in the relay box. The snap-fit ​​mechanism 6 and the snap-fit ​​block 5 secure the relay body 1. When the relay body 1 is in use, the heat dissipation mechanism 7 on the relay body 1 assists in heat dissipation. By using the snap-fit ​​block 5 on the relay body 1 to fasten under the strip plate of the relay box, and then having the installer manually pull the snap-fit ​​mechanism 6 to snap onto the strip plate, the relay body 1 can be stably fixed in the relay box. This reduces the possibility of momentary impact on the snap-fit ​​block 5, which could reduce its service life, when using traditional spring clips for fixing.

[0037] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The snap-fit ​​mechanism 6 includes a snap-fit ​​plate 61 disposed on the relay body 1. Sliding blocks 63 are fixed at both ends of the snap-fit ​​plate 61. A sliding groove 62 is provided on the relay body 1. The sliding blocks 63 are located in the sliding groove 62 and are slidably connected to the relay body 1. A moving limit component 64 is provided between the snap-fit ​​plate 61 and the relay body 1.

[0038] In addition, the moving limit assembly 64 includes two moving blocks 642 symmetrically arranged on both sides of the relay body 1. A metal wire 641 is provided between the moving block 642 and the sliding block 63. The metal wire 641 passes through the relay body 1, and both ends of the metal wire 641 are fixedly connected to the moving block 642 and the sliding block 63.

[0039] Furthermore, support blocks 643 are fixed on both sides of the relay body 1. Fixed blocks 644 are slidably connected to the support blocks 643. Fixed blocks 644 are fixedly connected to the moving blocks 642. Two symmetrical fixed blocks 645 are slidably connected to the support blocks 643. The snap-fit ​​block 5 abuts against the fixed blocks 645. Snap-fit ​​teeth are provided on both the fixed blocks 644 and the fixed blocks 645, and they face opposite directions.

[0040] Furthermore, a snap-fit ​​spring 646 is provided between the fixing block 645 and the support block 643, and both ends of the snap-fit ​​spring 646 are fixedly connected to both the fixing block 645 and the support block 643.

[0041] Furthermore, a support spring 65 is provided inside the sliding groove 62, and both ends of the support spring 65 are fixedly connected to the sliding block 63 and the relay body 1.

[0042] When installing the relay body 1, first place the side of the relay body 1 with the locking block 5 against the strip plate inside the relay box, so that the locking block 5 is secured to the bottom of the strip plate by the contact block 4. Then, let the entire relay body 1 rest against the strip plate. Then, the installer pulls and moves it. The moving block 642 slides on the support block 643 under the support of the fixed block 644. When the moving block 642 moves, it drives the metal wire 641. The metal wire 641 drives the sliding block 63. When the sliding block 63 moves in the sliding groove 62, it compresses the support spring 65. When the sliding block 63 moves, it drives the locking plate 61, so that the locking plate 61 is secured to the strip plate. Behind the relay body 1, the relay body 1 is secured to the strip plate of the relay box using the snap-fit ​​plate 61 and snap-fit ​​block 5. Then, under the push of the snap-fit ​​spring 646, the fixing block 645 is secured to the fixing block 644, limiting the movement of the fixing block 644 and keeping the snap-fit ​​plate 61 extended. The snap-fit ​​block 5 is secured to the bottom of the strip plate in the relay box, and then the installer manually extends the snap-fit ​​plate 61, securing the snap-fit ​​plate 61 and snap-fit ​​block 5 to the strip plate of the relay box. This facilitates the installation of the relay body 1 and reduces the possibility of momentary impact on the snap-fit ​​block 5 when the transmission is installed using the spring snap-fit, which could affect its service life.

[0043] Reference Figure 2 , Figure 3 and Figure 5 The heat dissipation mechanism 7 includes a heat-conducting copper sheet 71 fixed on the side of the relay body 1 away from the contact point 2, a heat-conducting copper sheet 73 disposed on the heat-conducting copper sheet 71, and a heat-conducting copper sheet 72 fixed between the heat-conducting copper sheet 71 and the heat-conducting copper sheet 73.

[0044] In addition, the thermally conductive copper sheet 272 is wavy.

[0045] When the relay body 1 is in normal use, the heat generated by the relay body 1 is transferred to the heat-conducting copper sheet 71. The heat-conducting copper sheet 71 then transfers the heat to the heat-conducting copper sheet 72. The wavy shape of the heat-conducting copper sheet 72 increases the contact area with the air, allowing the heat absorbed by the heat-conducting copper sheet 72 to be transferred into the air. At the same time, the heat-conducting copper sheet 73 further assists in heat dissipation and also makes the surface of the relay body 1 flat, reducing the possibility of the relay body 1 shifting due to the wavy shape of the heat-conducting copper sheet 72 during installation. By using the heat-conducting copper sheet 71 for heat conduction and then using the heat-conducting copper sheet 72 to transfer the heat into the air, the possibility of the relay body 1 being affected by high temperature during normal operation can be reduced.

[0046] Working principle: When installing the relay body 1, the side of the relay body 1 with the contact block 4 and the snap-fit ​​block 5 is directly placed into the relay box specifically for installing relays, so that the relay body 1 abuts against the strip plate of the external relay box, and the snap-fit ​​block 5 is fastened to the bottom of the strip plate of the relay box. Then, the installer pulls and moves it. The moving block 642 slides on the support block 643 under the support of the fixed block 644. When the moving block 642 moves, it drives the metal wire 641. The metal wire 641 drives the sliding block 63. When the sliding block 63 moves in the sliding groove 62, it compresses the support spring 65. When the sliding block 63 moves, it drives the snap-fit ​​plate 61, so that the snap-fit ​​plate 61 is fastened to the back of the strip plate. The snap-fit ​​plate 61 and the snap-fit ​​block 5 are used to fasten the relay body 1 to the relay box. On the strip plate, under the push of the snap-fit ​​spring 646, the second fixing block 645 is snapped onto the first fixing block 644, which limits the movement of the first fixing block 644 and keeps the snap-fit ​​plate 61 in the extended state, thus completing the installation and fixing of the relay body 1. When the relay body 1 is in normal use, the heat generated by the relay body 1 is transferred to the first heat-conducting copper sheet 71, which in turn transfers the heat to the second heat-conducting copper sheet 72. The second heat-conducting copper sheet 72 is wavy, which increases the contact area with the air, allowing the heat absorbed by the second heat-conducting copper sheet 72 to be transferred into the air. At the same time, the third heat-conducting copper sheet 73 further assists in heat dissipation and also makes the surface of the relay body 1 flat, reducing the possibility of the relay body 1 shifting due to the wavy heat-conducting copper sheet 72 during installation.
