Description

Technical Field

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

[0002] A relay is an automatic electrical control switching device that uses a small current to control a large current. Its core function is to use an input signal to trigger electromagnetic effects or mechanical actions, thereby controlling the connection or disconnection of a high-power circuit. Relays are usually installed and connected to external circuits through a relay base. However, current relays only have pins connected to the terminals on the base, making it very easy for the relay to separate from the base.

[0003] An existing relay socket includes a base and a snap-fit ​​seat disposed on the base. The snap-fit ​​seat is used to fix the relay. Several lifting mechanisms are rotatably disposed on the snap-fit ​​seat. The lifting mechanism includes a fixed rod, a rotating block connected to the fixed rod, and an ejector rod connected to the rotating block. The snap-fit ​​seat has a mounting groove for the relay to extend into. The rotating block is rotatably connected to the snap-fit ​​seat.

[0004] However, when the aforementioned relay socket is used to install a relay, the various fixing rods are prone to relative wobbling, which makes the locking effect of the latch seat on the relay poor. This causes the relay to loosen and separate from the latch seat, resulting in low connection stability between the relay and the socket, which needs to be improved. Utility Model Content

[0005] To improve the connection stability between the relay and the socket, this application provides a relay socket.

[0006] The relay socket provided in this application adopts the following technical solution: A relay socket includes a latching seat, a plurality of springs disposed on the latching seat, and a plurality of lifting mechanisms rotatably disposed on the latching seat. The lifting mechanism includes a fixed rod, a rotating block connected to the fixed rod, and an ejector rod connected to the rotating block. The rotating block is rotatably connected to the latching seat. The latching seat has an installation groove for the relay to extend into. The latching seat has a plurality of limiting structures, which abut against each pair of fixed rods.

[0007] By adopting the above technical solution, the limiting structure can prevent relative wobbling between the fixing rods, thereby making the limiting effect of the buckle seat on the relay stable. This makes it less likely for the relay to loosen when installed in the buckle seat, thus making it less likely for the relay to separate from the socket and improving the connection stability between the relay and the socket.

[0008] Optionally, the end of the fixing rod away from the ejector rod is provided with a hook. When the relay is inserted into the mounting groove, the hook is located on the side of the relay away from the ejector rod. The fixing rod is provided with a limiting member for fixing the fixing rod in a vertical position.

[0009] By adopting the above technical solution, when connecting the relay to the base, simply rotate the fixing rod away from the latching seat, then insert the relay into the mounting slot. As the relay enters the slot, it pushes the ejector rod towards the latching seat, causing the fixing rod to rotate and reset towards the latching seat. This positions the ejector rod on the side of the relay closest to the latching seat, and the hook on the side of the relay furthest from both the ejector rod and the latching seat. At this point, the fixing rod is held vertically by the limiting component, preventing it from rotating relative to the latching seat. This ensures the hook remains on the side of the relay furthest from both the ejector rod and the latching seat, preventing the relay from moving out of the mounting slot. Compared to fixing the relay with a fixing hook, the hook is less likely to move relative to the relay, resulting in a more stable connection between the relay and the socket.

[0010] When it is necessary to separate the relay from the latching seat, simply unlock the limiting piece first, and then rotate the fixing rod away from the latching seat. Rotating the fixing rod away from the latching seat will cause the ejector rod to rotate away from the latching seat, thus pushing the relay away from the latching seat. At this point, the hook is no longer located on the side of the relay away from the latching seat, meaning the hook no longer limits the relay, making it easy to remove the relay from the mounting slot. The operation is simple.

[0011] Optionally, the buckle seat includes a base plate, the limiting structure is disposed on the base plate, the limiting member includes positioning protrusions disposed on two side walls of the fixing rod near the limiting structure, the side walls of the limiting structure are provided with limiting grooves, and when the relay extends into the mounting groove, the positioning protrusions are located in the limiting grooves.

[0012] By adopting the above technical solution, when the relay is installed in the mounting groove, the positioning protrusion will rotate into the limiting groove along with the fixing rod. The groove wall of the limiting groove can prevent the positioning protrusion from moving away from the buckle seat, so that the fixing rod is not easy to rotate away from the buckle seat, thus fixing the fixing rod in the vertical position, thereby fixing the position of the hook, and the hook has a good limiting effect on the relay.

[0013] Optionally, the positioning protrusion is provided with a guide slope, which is inclined towards the fixing rod along the limiting structure.

[0014] By adopting the above technical solution, when the relay is inserted into the mounting slot, the fixing rod will rotate into the space between the limiting structures. The guide slope can guide the fixing rod in the direction of entering the space between the limiting structures, making it easier for the fixing rod to extend into the mounting slot, and at the same time, it facilitates the positioning protrusion to extend into the limiting slot, thereby limiting the fixing rod. When it is necessary to remove the relay from the mounting slot, only a little force is needed to move the positioning protrusion out of the limiting slot, thereby rotating the fixing rod away from the buckle seat.

[0015] Optionally, the buckle seat has several receiving grooves for accommodating the rotating block. The two groove walls of the receiving grooves are connected along the rotation direction of the rotating block. The rotating block has rotating rings on two opposite side walls. The rotating rings are disposed on the two side walls of the rotating block near the groove wall of the receiving groove. The groove wall of the receiving groove has positioning holes for the rotating rings to rotate within.

[0016] By adopting the above technical solution, the rotating block achieves rotation relative to the buckle seat by rotating the rotating ring in the positioning hole, which makes the structure of the rotating block and the buckle seat simple and eliminates the need for other rotating connection devices, making it easy to process.

[0017] Optionally, each of the rotating rings is provided with a positioning mark, the positioning mark is connected to the rotating block, and the maximum distance between the positioning mark and the rotating block is less than the maximum distance between the rotating ring and the rotating block. The limiting groove is connected to the receiving groove, and the positioning mark extends into the limiting groove.

[0018] By adopting the above technical solution, when the rotating ring rotates in the positioning hole, the positioning mark will rotate in the limiting groove. The groove wall of the limiting groove can limit the positioning mark, so that the positioning mark can only rotate at a certain angle, thereby limiting the rotation angle of the rotating ring. This keeps the rotation angle of the fixing rod and the ejector rod within a fixed range, so that the relay is not unable to be limited due to the excessive rotation angle of the fixing rod and the ejector rod. It also eliminates the need to manually adjust the rotation angle of the fixing rod and the ejector rod, thereby improving the stability of the lifting mechanism and the convenience of using the relay socket.

[0019] Optionally, the limiting structure is provided with positioning ribs on the side near the ejector rod.

[0020] By adopting the above technical solution, a socket typically houses multiple relays, with the relay pins extending into the mounting socket. When the relay is inserted into the mounting groove, the positioning ribs limit its movement, preventing displacement and thus reducing the risk of pin bending or damage. When the relay is installed in the socket, the positioning ribs are spaced between each relay, fixing its position on the mounting socket and making the relay more stable when installed.

[0021] Optionally, the buckle seat further includes a plurality of limiting pieces disposed on the base plate. The number of the limiting pieces is equal to the number of the limiting structures and they correspond one-to-one. When the relay is installed on the buckle seat, the limiting pieces are located on both sides of each relay.

[0022] By adopting the above technical solution, when the relay is installed on the socket, not only are the positioning ribs used to limit the position of each relay, but the limiting plates can also fix the position of the relay, further improving the stability of the relay when it is installed on the socket.

[0023] Optionally, it also includes a base connected to the buckle seat, the base having a placement groove for the buckle seat to extend into, the base being used to connect an external circuit and a relay, the fixing rod including a relief block disposed at the end of the fixing rod away from the ejector rod, the hook being disposed on the side of the relief block near the ejector rod, the relief block having a relief slope, the relief slope being inclined along the relief block toward the hook.

[0024] By adopting the above technical solution, when it is necessary to remove the relay from the mounting slot, the fixing rod can be rotated directly away from the buckle seat. The inclined surface allows the fixing rod to rotate a larger angle away from the buckle seat, ensuring that the wall of the mounting slot does not obstruct the rotation of the fixing rod. This ensures that the hook can be moved outside the trajectory for the relay to enter and exit the mounting slot, allowing the relay to enter and exit the mounting slot normally. At the same time, it allows the ejector rod to be raised to a larger angle, resulting in a better lifting effect on the relay and facilitating the installation and removal of the relay.

[0025] In summary, this application includes at least one of the following beneficial technical effects: By providing a limiting structure on the buckle seat, the fixing rod is not easy to shake when the relay is installed in the socket, thus improving the connection stability between the relay and the socket; When it is necessary to separate the relay from the latch seat, simply rotate the fixing rod; the operation is simple. 3. The rotation angle of the lifting mechanism is limited by the positioning marks and positioning protrusions, the socket has a good fixing effect on the relay, and the socket is easy to use.

[0034] The following is in conjunction with the appendix Figure 1-7 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 snap-fit ​​base 1, a plurality of springs 2 disposed on the snap-fit ​​base 1, and a base 3 connected to the snap-fit ​​base 1. The base 3 has a placement groove 31 for the snap-fit ​​base 1 to extend into. The base 3 is used to connect an external circuit and a relay. When the relay is installed on the socket, the relay pins extend into the snap-fit ​​base 1, and the springs 2 of the snap-fit ​​base 1 extend into the base 3.

[0037] Reference Figure 3 The latching base 1 includes a base plate 11, a plurality of limiting structures 12 disposed on the base plate 11, and a plurality of limiting pieces 13 disposed on the base plate 11. The latching base 1 has a mounting groove 14 for the relay to extend into. In this embodiment, the number of limiting structures 12 is preferably four; however, the specific number of limiting structures 12 can be selected according to customer requirements in other cases. In this embodiment, the limiting structure 12 is preferably a limiting block; however, other limiting structures 12 can be selected according to customer requirements in other cases, and their shapes are not limited.

[0038] Reference Figure 3Multiple relays are typically mounted on a single latching base 1. To prevent the relays from shifting during insertion into the mounting slot 14, positioning ribs 121 are provided on the side of the limiting structure 12 near the relays, with the positioning ribs 121 located on both sides of each relay. Limiting plates 13 are also located on both sides of each relay, further enhancing the stability of the relays when mounted on the latching base 1. The number of limiting structures 12, limiting plates 13, and positioning ribs 121 are equal and correspond one-to-one.

[0039] Reference Figure 3 and Figure 4 The latching seat 1 is rotatably equipped with several lifting mechanisms 4. Each lifting mechanism 4 includes a fixed rod 41, a rotating block 42 connected to the fixed rod 41, and an ejector rod 43 connected to the rotating block 42. The fixed rod 41 includes a relief block 411 located at the end of the fixed rod 41 away from the ejector rod 43. The fixed rod 41 is positioned between every two limiting structures 12, which prevent the fixed rod 41 from shaking, thus enhancing the latching seat 1's fixing effect on the relay. The relief block 411 has a relief slope 412, and a hook 413 is provided on the side of the relief block 411 near the ejector rod 43.

[0040] Reference Figure 3 and Figure 4 With the above configuration, when the relay is inserted into the mounting slot 14, the hook 413 is located on the side of the relay away from the ejector rod 43. The hook 413 can prevent the relay from moving out of the mounting slot 14, making the relay installation more secure. The clearance slope 412 is inclined along the clearance block 411 towards the hook 413. This configuration allows the fixing rod 41 to rotate a larger angle away from the latch seat 1, thereby improving the lifting effect of the lifting mechanism 4 on the relay.

[0041] Reference Figure 3 and Figure 5 The buckle seat 1 has several receiving grooves 15 for accommodating the rotating block 42 and several fixing grooves 16 for accommodating the ejector rod 43. The rotating block 42 is rotatably connected to the groove wall of the receiving groove 15, and the two groove walls of the receiving groove 15 are connected along the rotation direction of the rotating block 42.

[0042] Reference Figure 4 and Figure 6The rotating block 42 has rotating rings 421 on two opposite side walls, and the rotating rings 421 are located on the two side walls of the rotating block 42 near the wall of the receiving groove 15. The wall of the receiving groove 15 has positioning holes 151 for the rotating rings 421 to rotate within. Each rotating ring 421 is fixed with a positioning mark 422, which is connected to the rotating block 42. The maximum distance between the positioning mark 422 and the rotating block 42 is less than the maximum distance between the rotating rings 421 and the rotating block 42. The side wall of the limiting structure 12 has a limiting groove 122, which communicates with the receiving groove 15. The positioning mark 422 extends into the limiting groove 122.

[0043] Reference Figure 4 and Figure 6 With the above configuration, when the rotating ring 421 rotates in the positioning hole 151, it will drive the rotating block 42 to rotate, thereby driving the fixed rod 41 and the ejector rod 43 to rotate. The groove wall of the limiting groove 122 can limit the rotation angle of the positioning mark 422, thereby limiting the rotation of the rotating ring 421, thus limiting the maximum rotation angle of the rotating block 42, the fixed rod 41, and the ejector rod 43. This makes it difficult for the ejector rod 43 to rotate out of the buckle seat 1, reducing the possibility of needing to manually adjust the position of the fixed rod 41 and the ejector rod 43, and improving the ease of use when using the socket.

[0044] Reference Figure 7 The fixing rod 41 is provided with a limiting member 5 for fixing the fixing rod 41 in a vertical position. The limiting member 5 includes positioning protrusions 51 provided on two side walls of the fixing rod 41 near the limiting structure 12, and the positioning protrusions 51 are provided with guide slopes 52. The guide slopes 52 are inclined along the limiting structure 12 toward the fixing rod 41. When the relay is inserted into the mounting groove 14, the positioning protrusions 51 are located in the limiting groove 122. The groove wall of the limiting groove 122 can prevent the positioning protrusions 51 from moving out of the limiting groove 122, thereby limiting the position of the fixing rod 41.

[0045] The implementation principle of a relay socket according to an embodiment of this application is as follows: When the relay needs to be installed on the socket, simply rotate the fixing rod 41 away from the latching seat 1, so that the hook 413 moves out of the latching seat 1. Then, insert the relay into the mounting groove 14. The relay will push the ejector rod 43 into the fixing groove 16, thereby causing the fixing rod 41 to rotate closer to the latching seat 1. Finally, the positioning protrusion 51 is located in the limiting groove 122. At this time, the hook 413 is located on the side of the relay away from the latching seat 1, so the hook 413 can prevent the relay from moving out of the mounting groove 14, thus improving the connection stability between the relay and the socket. Moreover, the limiting structure 12 abuts between every two fixing rods 41, making the fixing rod 41 less prone to shaking, thereby making the relay less prone to loosening.

[0046] When it is necessary to remove the relay from the mounting slot 14, simply rotate the fixing rod 41 away from the buckle seat 1. The fixing rod 41 will drive the ejector rod 43 to eject the relay from the mounting slot 14, thereby achieving quick installation and removal of the relay. The operation is simple.

[0047] 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.
