Description

Technical Field

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

[0002] A relay socket is a specialized base for installing and connecting relays. It plays an important role in electrical control systems. Through its standardized interface design, the relay socket has become an indispensable component in relay applications, balancing flexibility and reliability, and is widely used in various electrical control systems.

[0003] In related technologies, Chinese patent application number CN201910326594.8 discloses a relay socket, including a base, a housing, a spring, a spring, and a hook. The housing surface has a first through hole, the base passes through the first through hole and is connected to the housing via the hook; the hook is located at both ends of the base and is fixedly connected to the base; the base has several slots, the spring is located in the slots and abuts against the inner surface of the first through hole; the housing has several second through holes, with the diameter of the second through hole near the base being larger than the diameter of the second through hole away from the base; the spring is located in the second through hole and abuts against the base, thus achieving reliable contact between the relay pin and the socket spring.

[0004] However, when the aforementioned relay socket is used to install relays, the relay pins are only connected to the base via springs. If the springs are damaged, the relay is prone to detaching from the socket, resulting in poor retention of the relay by the socket and affecting the normal operation of the relay. Therefore, this needs to be improved. Utility Model Content

[0005] To improve the securing effect of the socket on the relay, this application provides a relay socket.

[0006] The relay socket provided in this application adopts the following technical solution:

[0007] A relay socket includes a base and a spring disposed on the base. The base includes a mounting portion and two fixing portions disposed opposite each other on the mounting portion. The mounting portion has a mounting groove for the relay to extend into. A push rod is slidably disposed on one of the fixing portions. A tripping rod is rotatably connected to the push rod. A fixing member is provided at the end of the tripping rod away from the push rod. The fixing member is used to fix one end of the tripping rod to the fixing portion without the push rod. The tripping rod is disposed on the side of the push rod away from the mounting portion.

[0008] By adopting the above technical solution, when installing a relay on a socket, the relay can be first inserted into the mounting slot, then the trip lever can be rotated towards the relay, and finally one end of the trip lever can be fixed to the fixing part by the fixing part. This makes the trip lever located on the side of the relay away from the mounting part. Even if the spring is damaged, the trip lever can prevent the relay from moving out of the mounting slot. The relay is not easy to move out of the mounting slot, which makes the connection between the relay and the socket highly stable and makes the socket have a good fixing effect on the relay.

[0009] Optionally, the fixing member includes a positioning protrusion provided on the release lever, and a positioning hole is provided at the end of the fixing part away from the mounting part. The positioning hole is used for the positioning protrusion to extend into, and the positioning protrusion can undergo elastic deformation.

[0010] By adopting the above technical solution, when one end of the trip lever needs to be fixed to the fixing part, simply rotate the trip lever towards the fixing part so that the positioning protrusion extends into the positioning hole. Once the positioning protrusion elastically deforms and extends into the positioning hole, it is not easily moved out, thus fixing the trip lever to the fixing part. This keeps the trip lever in a position away from the mounting part of the relay, providing good limiting effect for the relay. When it is necessary to move the relay out of the mounting slot, simply rotate the trip lever away from the mounting part so that the positioning protrusion moves out of the positioning hole. The operation is simple, and the structure of the fixing component is also simple.

[0011] Optionally, the fixing part is provided with a sliding hole for sliding the push rod, the mounting part is provided with a mounting cavity, the mounting cavity is connected to the sliding hole, a rocker is rotatably arranged in the mounting cavity, the cavity wall of the mounting cavity is provided with a through hole for one end of the rocker to extend into the mounting groove, and the other end of the rocker is located on the side of the push rod away from the release rod.

[0012] By adopting the above technical solution, when it is necessary to remove the relay from the mounting slot, simply push the push rod towards the rocker arm. This causes the end of the rocker arm near the push rod to rotate away from the fixed part, while the other end extends into the mounting slot. The rocker arm then pushes the relay out of the mounting slot, separating the relay pins from the socket springs. This eliminates the need for manual removal of the relay from the mounting slot, making the operation convenient and saving manpower. When installing the relay, the relay automatically pushes one end of the rocker arm into the mounting cavity, causing the other end of the rocker arm to push the push rod towards the trip lever. This fixes one end of the rocker arm in contact with the push rod and the other end in contact with the relay. This ensures that when the relay needs to be removed next time, pushing the push rod will push one end of the rocker arm into the mounting slot, thus pushing the relay out of the mounting slot. This facilitates the installation and removal of the relay.

[0013] Optionally, the rocker has abutment protrusions at both ends, and the abutment protrusions are located on the side of the rocker near the fixing part.

[0014] By adopting the above technical solution, when the two ends of the rocker arm abut against the push rod and the relay respectively, the abutment protrusions can increase the thickness of the two ends of the rocker arm, thereby enhancing the structural strength of the force-bearing points at both ends of the rocker arm, making the rocker arm less prone to damage, and thus improving the abutment and pushing effect between the rocker arm and the relay and push rod. At the same time, it can increase the height at which the rocker arm drives the relay to rise in the mounting groove, further facilitating the removal of the relay.

[0015] Optionally, a limiting block is provided on the wall of the sliding hole, and a limiting groove is provided on the side wall of the push rod for the limiting block to extend into, and the limiting block is slidably disposed in the limiting groove.

[0016] By adopting the above technical solution, when the push rod slides away from the rocker plate in the sliding hole, the limiting block slides in the limiting groove, thereby limiting the maximum sliding distance of the push rod. The limiting block can abut against the groove wall of the limiting groove near the rocker plate, making it difficult for the push rod to slide out of the sliding hole, thus improving the stability of the sliding connection between the push rod and the fixing part. When the push rod slides towards the rocker plate, the limiting block will also abut against the groove wall of the limiting groove away from the rocker plate, thereby limiting the maximum sliding distance of the push rod towards the rocker plate. At this time, the push rod just pushes one end of the rocker plate into the mounting groove, thus preventing the push rod from applying excessive pressure to the rocker plate due to excessive force, thereby preventing damage to the rocker plate and extending the service life of the rocker plate.

[0017] Optionally, an indicator plate may be detachably provided on the side of the trip lever away from the mounting part. When the relay is installed on the socket, the indicator plate is located on the side of the trip lever away from the relay.

[0018] By adopting the above technical solution, when the relay is installed on the socket, the relevant information of the corresponding relay can be written on the label plate. This allows the relay parameter information to be obtained without removing the relay, facilitating understanding of the relay parameters during subsequent use. When the relay installed in the mounting slot is replaced, the label plate can also be replaced simultaneously or the information on the label plate can be rewritten. Simply remove the old label block from the trip lever, and then install the new label block on the trip lever. The operation is simple and facilitates changing the relay parameters.

[0019] Optionally, the mounting part is provided with a light guide hole, and a light guide column is provided in the light guide hole. A clearance groove for the LED indicator light to extend into is opened on the side of the mounting part away from the fixing part, and the clearance groove is connected to the light guide hole.

[0020] By adopting the above technical solution, when the relay is installed on the socket and put into operation, the socket's spring will be connected to the circuit board, and the LED indicator on the circuit board will indicate the working status of the relay. The light guide column can guide the light of the LED indicator to the outside of the socket, making it easier to observe the working status of the relay and making it less likely for the relay socket to block the light of the LED indicator.

[0021] Optionally, splicing grooves are respectively provided on the two opposite outer side walls of the mounting part, and each splicing groove is provided with a splicing block. The cross section of the splicing groove along the direction perpendicular to the direction in which the relay extends into the mounting groove is trapezoidal. The wide sides of the two splicing grooves are close to each other. The groove walls of the two splicing grooves away from the fixing part are open, and the groove walls near the fixing part are closed. The splicing block includes two snap-fit ​​parts. The cross section of the snap-fit ​​parts along the direction perpendicular to the direction in which the relay extends into the mounting groove is trapezoidal. The narrow sides of the two snap-fit ​​parts are connected together.

[0022] By adopting the above technical solution, when multiple relay sockets need to be connected together, simply slide one locking part of the splicing block into the splicing groove from the side away from the fixed part, so that one locking part is located in the splicing groove, and then extend the other locking part into the splicing groove of another socket. By connecting multiple relay sockets together in this way, the groove wall can prevent the splicing block from moving out of the splicing groove in a direction perpendicular to the direction in which the relays extend into the mounting groove, ensuring a firm connection between the relay sockets and facilitating the centralized arrangement and installation of the relays.

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

[0024] 1. By setting a push rod on the base and rotatably connecting a trip rod to the push rod, the trip rod can prevent the relay from moving out of the mounting slot, thereby improving the fixing effect of the relay socket on the relay;

[0025] 2. A rocker plate is provided in the mounting cavity. The rocker plate is pushed into the mounting slot by a push rod, thereby pushing the relay out of the mounting slot for easy removal of the relay;

[0026] 3. A limiting groove is provided on the side wall of the push rod, and a limiting block is provided on the wall of the sliding hole. The limiting block is slidably set in the limiting hole, thereby limiting the maximum sliding distance of the push rod, making it difficult for the push rod to disengage from the sliding hole or damage the rocker.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a relay socket.

[0036] Reference Figure 1 and Figure 2 A relay socket includes a base 1 and a spring 2 disposed on the base 1, wherein the spring 2 is used to connect relay pins or connect the socket to a circuit board. The base 1 includes a mounting part 11 and two fixing parts 12 disposed opposite to each other on the mounting part 11. The mounting part 11 has a mounting groove 111, and the two fixing parts 12 have fixing grooves 121 that communicate with the mounting groove 111. The mounting groove 111 and the fixing groove 121 communicate with each other, and both the mounting groove 111 and the fixing groove 121 are used for the relay to extend into.

[0037] Reference Figure 2 and Figure 3 The mounting part 11 is provided with a light guide hole 112, and a light guide post 113 is fixed in the light guide hole 112. A clearance groove 114 is provided on the side of the mounting part 11 away from the fixing part 12, and the clearance groove 114 communicates with the light guide hole 112. The circuit board generally has an LED indicator light for indicating the working status of the relay. When the relay socket is connected to the circuit board, the LED indicator light extends into the clearance groove 114, and the light guide post 113 is used to guide the light of the LED indicator light to the outside of the socket, making it easy to observe the working status of the relay.

[0038] Reference Figure 2 and Figure 4 The mounting part 11 has two opposite outer side walls with splicing grooves 115 respectively. Each splicing groove 115 contains a splicing block 116, which includes two snap-fit ​​parts 117. Both the splicing groove 115 and the snap-fit ​​parts 117 have trapezoidal cross-sections in the direction perpendicular to the direction in which the relay extends into the mounting groove 111. The wide sides of the two splicing grooves 115 are close to each other, with the groove wall of the splicing groove 115 away from the fixing part 12 open and the groove wall near the fixing part 12 closed. The narrow sides of the two snap-fit ​​parts 117 are connected together.

[0039] Reference Figure 2 and Figure 4 With the above settings, relays can sometimes be used to control multiple devices to work together. When it is necessary to use relays to centrally control multiple devices, two relay sockets can be connected together by splicing block 116. Simply insert the two snap-fit ​​parts 117 of splicing block 116 into the splicing slots 115 of different sockets. The operation is simple, the connection strength between sockets is high, and the flexibility of using relay sockets is enhanced.

[0040] Reference Figure 3 One of the fixing parts 12 has a sliding hole 122, and a push rod 123 is slidably disposed in the sliding hole 122. A limit groove 124 is provided on the side wall of the push rod 123. A limit block 125 is fixed on the hole wall of the sliding hole 122, and the limit block 125 is slidably disposed in the limit groove 124. The groove wall of the limit groove 124 can abut against the limit block 125, thereby limiting the maximum sliding distance of the push rod 123 and making it difficult for the push rod 123 to move out of the sliding hole 122.

[0041] Reference Figure 3 The mounting part 11 has a mounting cavity 118, which communicates with the sliding hole 122. A rocker plate 3 is rotatably mounted in the mounting cavity 118. Both ends of the rocker plate 3 have abutment protrusions 31, which are located on the side of the rocker plate 3 near the fixing part 12. The cavity wall of the mounting cavity 118 near the fixing part 12 has a through hole 119 for the rocker plate 3 to extend into the mounting groove 111. One end of the rocker plate 3 is located on the side of the push rod 123 away from the fixing part 12.

[0042] Reference Figure 3 and Figure 5With the above configuration, when the push rod 123 slides towards the rocker plate 3, the other end of the rocker plate 3 extends into the mounting groove 111, thereby pushing the relay out of the mounting groove 111. When the relay extends into the mounting groove 111, the relay will push the rocker plate 3 to automatically reset, facilitating the next removal of the relay. The two abutting protrusions 31 abut against the relay and the push rod 123 respectively, increasing the thickness of the rocker plate 3. Therefore, the abutting protrusions 31 can increase the lifting height of the rocker plate 3 on the relay.

[0043] Reference Figure 2 A release lever 4 is rotatably connected to the push rod 123. The release lever 4 is located at the end of the push rod 123 away from the rocker arm 3. A fixing member 41 is fixed to the end of the release lever 4 away from the push rod 123. The fixing member 41 includes a positioning protrusion 411 on the release lever 4. The positioning protrusion 411 is capable of elastic deformation. In this embodiment, the material of the positioning protrusion 411 is preferably plastic. In other cases, other materials capable of elastic deformation can be selected according to customer needs. The positioning protrusion 411 is located on two opposite side walls of the release lever 4. The end of the release lever 4 away from the push rod 123 extends into the fixing groove 121. Two positioning holes 126 are opened on the two opposite groove walls of the fixing groove 121. The positioning holes 126 are used for the positioning protrusion 411 to extend into. The positioning holes 126 are located at the end of the fixing part 12 away from the mounting part 11.

[0044] Reference Figure 2 With the above settings, when the trip lever 4 extends into the fixing groove 121, the positioning protrusion 411 will extend into the positioning hole 126, thereby limiting the trip lever 4. At this time, the trip lever 4 can prevent the relay from moving out of the mounting groove 111, so that the relay is securely installed.

[0045] Reference Figure 1 A label plate 42 is detachably mounted on the side of the trip lever 4 away from the mounting part 11. In this embodiment, the label plate 42 is preferably inserted into the trip lever 4. In other cases, other detachable connection methods can be selected according to customer needs, such as snap-fit ​​connection, etc. Any method that can connect and detach the label plate 42 and the trip lever 4 is acceptable. The label plate 42 shows the parameter information of the installed relay. When the relay is installed on the socket, the label plate 42 is located on the side of the trip lever 4 away from the relay, making it easy to observe the basic information of the relay.

[0046] The implementation principle of a relay socket according to an embodiment of this application is as follows: When it is necessary to install the relay on the socket, simply insert the relay into the mounting groove 111 so that the relay pins extend into the socket spring 2. At the same time, one end of the rocker 3 enters the mounting cavity 118, and the other end pushes the push rod 123 away from the mounting part 11. This causes the rotating connecting shaft of the trip lever 4 and the push rod 123 to rise to a position higher than the relay. Then, the trip lever 4 is rotated towards the positioning hole 126 so that the positioning protrusion 411 enters the positioning hole 126. The trip lever 4 can prevent the relay from moving out of the mounting groove 111.

[0047] When it is necessary to remove the relay from the mounting slot 111, the trip lever 4 can be rotated away from the positioning hole 126 first, so that the positioning protrusion 411 moves out of the positioning hole 126. Then, continue to rotate until the trip lever 4 is parallel to the push rod 123. Then, push the trip lever 4 towards the mounting part 11, so that the push rod 123 pushes the rocker 3 to rotate, so that one end of the rocker 3 extends into the mounting slot 111, thereby pushing the relay out of the mounting slot 111, which facilitates the installation and removal of the relay, and at the same time strengthens the fixing effect of the relay socket on the relay.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
