Description

Technical Field

[0001] This utility model relates to the field of relay sockets, and in particular to a locking device for a relay socket and a relay socket. Background Technology

[0002] In existing technology, relays are often fixed to sockets using a snap ring structure, see [link to relevant documentation]. Figure 24 and Figure 25 The snap ring structure engages with the corresponding mounting groove 3 on the socket 2 via a protrusion 1 or a similar structure, utilizing the elastic deformation of the plastic part itself to generate a fixing force. Its working principle is a lever-type design with a pivot 4 as the fulcrum, using a hinged fastener 5 to limit the relay 6 to its mounting position on the socket 2. The core of this structural design lies in achieving rapid fixing and disassembly of the relay through the mechanical cooperation between the snap ring structure and the base, making it widely used in the installation of small relays.

[0003] However, the aforementioned snap ring structure has a significant technical defect: to ensure smooth movement of the snap ring when switching between open and closed states, the engagement force between the protrusion and the mounting groove must be strictly controlled (it cannot be too large). This directly results in a relatively small preload on the relay by the snap ring. When the relay is subjected to an outward pull-out force (such as external impact, vibration, etc.), the relay is prone to outward movement, and may even force the protrusion of the snap ring to detach from the mounting groove and unfasten, causing the relay to loosen or fall off, affecting the operational stability of the equipment. Utility Model Content

[0004] The main purpose of this utility model is to overcome the shortcomings of insufficient pre-tightening force and weak impact and vibration resistance of the existing snap ring structure, and to propose a locking device and relay socket that can provide reliable pre-tightening force, ensure stable fixation of the relay, and is easy to operate.

[0005] The present invention adopts the following technical solution:

[0006] A locking device for a relay socket is installed on an assembly groove in the socket body, the assembly groove being located around the relay mounting position of the socket body. The device includes a slider, which has a connected operating component and a sliding component. The sliding component has a resilient latch, and the operating component has a transmission component that engages with the latch. The operating component can be pushed to cause the sliding component to slide relative to the assembly groove along the length of the slider, so that the sliding component is partially located on or away from the top surface of the relay. The sliding component is locked at a corresponding position by engaging with the side wall of the assembly groove through the latch. The operating component can be pressed to actuate the transmission component, causing the latch to deform along the width of the slider to release the lock on the corresponding position of the sliding component.

[0007] The slider includes two buckles that extend along the length direction and are symmetrically arranged. The two buckles are connected at one end in the length direction of the slider and connected to the operating member. The other end of the two buckles in the length direction of the slider extends obliquely away from the center of the slider along the width direction of the slider.

[0008] The operating component includes two symmetrically arranged transmission parts that extend away from the center of the slider along the width direction of the slider. The ends of the two transmission parts are respectively opposite to the outer sides of the two buckles in the width direction of the slider, and when the operating component is pressed, they contact and engage to drive the buckles to undergo elastic deformation along the width direction of the slider.

[0009] The buckle is provided with a buckle head at one end of the slider away from the connection of the operating component along the length direction. The buckle head is provided with a guide slope on the side opposite to the side wall of the assembly groove. When the slider slides toward the side where the relay is located, the guide slope abuts against the side wall of the assembly groove, forcing the buckle to deform. The side wall of the assembly groove is provided with a first locking groove and a second locking groove that are spaced apart along the length direction of the slider so that the buckle head can be engaged to achieve locking.

[0010] The first end of the operating member is connected to one end of the slider in the length direction of the slider, and the second end of the operating member extends along the length direction of the slider and is inclined upward; the transmission part is disposed between the first end and the second end of the operating member.

[0011] The buckle has a first inclined surface on its outer side in the width direction, and the transmission part has a second inclined surface on the side opposite to the first inclined surface. The first and second inclined surfaces extend from top to bottom and are inclined away from the center of the slider.

[0012] A relay socket includes a socket body and a locking device for the relay socket. The mounting groove is located near the top surface of the relay and extends along the length of the slider to the relay mounting position. The side wall of the mounting groove is provided with a first locking groove and a second locking groove that cooperate with the buckle to achieve locking at the corresponding position.

[0013] The socket body has two side plates on the outer periphery of the relay mounting position near the top surface of the relay, and the two side plates form the mounting groove with an opening at the top; the side plates are provided with a first locking groove and a second locking groove that extend along the width direction of the slider; the top of the operating member is exposed outside the opening of the mounting groove.

[0014] The assembly groove has two limiting blocks spaced apart along the length of the slider on its sidewall in the width direction of the slider. The two limiting blocks are located at the top of the assembly groove and extend towards the center along the width direction of the slider. The two limiting blocks form limiting surfaces on opposite sides. The operating member has a protrusion on the side opposite to the sidewall. When the slider is locked, the protrusion abuts against the limiting surfaces of the two limiting blocks respectively.

[0015] The assembly groove has a mounting opening at the end of the slider away from the relay in the length direction for the slider to be inserted. The limiting block near the mounting opening has a third inclined surface, which is located on the side of the limiting block opposite to the mounting opening. The protrusion has a fourth inclined surface on the side of the slider facing the relay in the length direction for cooperating with the third inclined surface to guide the slider to be inserted when it is inserted.

[0016] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0017] 1. In this utility model, the relay is physically locked by the sliding part pressing against the top surface of the relay. Combined with the snap-fit ​​positioning between the buckle and the side wall of the assembly groove, a double fixing structure is formed, which increases the fixing pre-tightening force and effectively prevents the relay from loosening and falling off under vibration or impact.

[0018] 2. In this utility model, the buckle has an outwardly inclined elastic structure at the free end of the slider in the length direction, which gives it a natural elastic pre-tightening tendency. It can reliably abut against the side wall of the assembly groove without the need for additional elastic elements, providing a stable basis for snap-fit ​​locking.

[0019] 3. In this utility model, the operating component and the sliding component are linked by the inclined surface of the transmission part and the buckle part. When the operating component is pressed, the inclined surface converts the pressing force into the deformation driving force of the buckle part along the width direction, so that the buckle part contracts inward synchronously, thereby achieving fast and reliable unlocking.

[0020] 4. In this utility model, the transmission part and the buckle part adopt a symmetrically arranged inclined surface mating structure to ensure that the force is balanced during the pressing action, avoid the action jamming caused by unilateral load, and improve the stability and response consistency of the operation process.

[0021] 5. In this utility model, the side wall of the assembly groove is provided with a first locking groove and a second locking groove that are spaced apart along the length direction. After the buckle slides into place, it can be locked into the corresponding groove to achieve positioning. Combined with the limiting structure of the slider's sliding stroke, it ensures that the slider stays stably in the locked or unlocked position.

[0022] 6. In this utility model, when the slider is installed into the assembly slot through the mounting port, the inclined surfaces of the protrusion and the limiting block, as well as the guide inclined surfaces of the buckle and the side plate end face, work together to achieve adaptive deformation and smooth insertion of the slider during the installation process, avoiding assembly jamming and improving assembly convenience and reliability.

[0023] 7. In this utility model, the operating component is set as a suspended end and tilted upward, with reserved elastic deformation space, which facilitates pressing operation. At the same time, the top of the operating component is exposed outside the assembly slot opening, which improves the convenience and visibility of operation and facilitates the quick completion of locking and unlocking actions.

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0052] The present invention will be further described below through specific embodiments.

[0053] See Figures 1 to 23 A locking device for a relay socket is installed on a mounting groove 20 of the socket body, the mounting groove 20 being located around a relay mounting position 30 on the socket body 29. The relay mounting position 30 is an area for mounting a relay 31, which can be a groove, cavity, or plane, etc. The locking device includes a slider 10, which has a connected operating member 11 and a sliding member 12; the sliding member 12 has a resilient latching portion 13. The end of the operating member 11 away from the sliding member 12 is suspended, allowing the operating member 11 to be pressed. The operating member 11 has a transmission portion 14 that corresponds to and cooperates with the latching portion 13. The operating member 11 can be pushed to cause the sliding member 12 to slide relative to the mounting groove 20 along the length of the slider 10, so that the sliding member 12 slides to a position partially on the top surface of the relay 31 to lock the relay 31, or the sliding member 12 slides away from the top surface of the relay 31 to unlock the relay 31. After the slider 12 slides into place, it locks the corresponding position through the snap-fit ​​engagement between the latch 13 and the side wall of the mounting groove 20. This corresponding position includes the position of the locking relay 31 and the position of the unlocking relay 31. The operating member 11 can be pressed to drive the transmission part 14 to move. The transmission part 14 drives the latch 13 to deform along the width direction of the slider 10, thereby releasing the snap-fit ​​lock between the latch 13 and the mounting groove 20, that is, releasing the latch 13 from locking the corresponding position of the slider 12, providing conditions for the slider 12 to switch positions.

[0054] In this embodiment, the sliding member 12 with a latching part 13 and the operating member 11 with a transmission part 14 are integrated on the slider 10. Pushing the operating member 11 causes the sliding member 12 to slide along the assembly groove 20. The sliding member 12 presses against or disengages from the top surface of the relay 31 to lock and unlock the relay 31. After sliding into place, the latching part 13 engages with the assembly groove 20 for positioning. Pressing the operating member 11 drives the latching part 13 to deform and unlock. The structure is simple and the operation is clear. Compared with the traditional snap ring structure, this dual fixing method of sliding member 12 pressing and latching part 13 engaging improves the fixing preload and enhances the resistance to impact and vibration, effectively reducing the risk of the relay 31 loosening and falling off, and ensuring stable operation of the equipment.

[0055] Furthermore, the slider 12 includes two symmetrically arranged latches 13 extending along its length. These latches 13 resemble two elastic arms. One end of each latch 13 is connected to the operating member 11 along the length of the slider 10. This structure ensures balanced force distribution during slider 10 movement, preventing jamming caused by unilateral load, and enhances the overall integrity of the connection between the latches 13, the operating member 11, and the slider 12. The other end of each latch 13 extends obliquely away from the center of the slider 10 along its width, giving the latches an outward elastic pre-tightening tendency. This allows for reliable contact with the sidewall of the mounting groove 20 without the need for additional elastic components, providing a basis for subsequent locking.

[0056] Furthermore, the operating component 11 includes two symmetrically arranged transmission parts 14 extending away from the center of the slider 10 along the width direction of the slider 10. The two transmission parts 14 are located on both sides of the operating component 11 in the width direction. The ends of the two transmission parts 14 are respectively opposite to the outer sides of the two latches 13 in the width direction of the slider 10. When the operating component 11 is pressed, the transmission parts 14 contact and engage with the latches 13, driving the latches 13 to undergo elastic deformation along the width direction of the slider 10, causing the two latches 13 to move closer together, thereby reducing the size of the slider 12 in its width direction and releasing the latches 13 from the side wall of the mounting groove 20. The symmetrical arrangement of the two transmission parts 14 corresponds one-to-one with the symmetrically arranged latches 13, ensuring balanced force when pressing the operating component 11, avoiding action jamming caused by unilateral load, and improving operational stability. Furthermore, the synchronous driving of the two transmission parts 14 to deform the corresponding latches 13 ensures that the unlocking action of the two latches 13 is consistent.

[0057] Specifically, the end of the transmission part 14 and the corresponding side of the buckle 13 are fitted with an inclined surface. The buckle 13 has a first inclined surface 17 on its outer side in the width direction, which is opposite to the side wall of the mounting groove 20. The end of the transmission part 14 has a second inclined surface 18 on the side opposite to the first inclined surface 17. The first inclined surface 17 and the second inclined surface 18 extend from top to bottom and are inclined away from the center of the slider 10. When the operating member 11 is not pressed, the first inclined surface 17 and the second inclined surface 18 do not contact or only partially contact each other. When the operating member 11 is pressed, the force exerted by the transmission part 14 on the buckle 13 is converted into a component force along the width direction of the slider 10 through the inclined surface contact, making the deformation of the buckle 13 more stable.

[0058] In this embodiment, the buckle 13 has a buckle head 15 at the end of the slider 10 away from the connection point of the operating member 11 along the length direction. The buckle head 15 has an outward convex structure relative to the main body of the buckle 13. The buckle head 15 has a guide slope 16 on the side opposite to the side wall of the mounting groove 20. When the slider 10 slides toward the side where the relay 31 is located, the guide slope 16 abuts against the side wall of the mounting groove 20, thereby forcing the buckle 13 to undergo elastic deformation along the width direction of the slider 10, so that the slider 10 can slide smoothly relative to the mounting groove 20; the side wall of the mounting groove 20 is provided with There are first locking grooves 21 and second locking grooves 22 spaced apart along the length of the slider 10. When the buckle 15 reaches the first locking groove 21 or the second locking groove 22, the buckle part 13 resets so that the buckle 15 is engaged in the first locking groove 21 or the second locking groove 22, thereby locking the slider 10 in the corresponding position. That is, when the buckle 15 is engaged in the first locking groove 21, the corresponding slider 10 is in the position of unlocking the relay 31, and when the buckle 15 is engaged in the second locking groove 22, the corresponding slider 10 is in the position of locking the relay 31.

[0059] The first end of the operating member 11 is connected to one end of the sliding member 12 along the length of the slider 10, with the connection point located at the junction of the two latches 13. The second end of the operating member 11 is a suspended end, extending along the length of the sliding member 12 and inclined upward. The transmission part 14 is disposed between the first and second ends of the operating member 11, also located between the two ends of the sliding member 12 along its length, and the end of the transmission part 14 extends downward to the outside of the latch 13.

[0060] In this embodiment, the first end of the operating member 11 is fixed, while the second end is suspended and tilted upwards, providing a certain amount of elastic deformation space for the operating member 11 to meet the needs of pressing actions. The second end of the operating member 11 is located above the transmission part 14, which facilitates the sliding of the slider 10 or makes it easy to be pressed.

[0061] The latching device of this embodiment is adapted for use with a relay socket and is assembled in the mounting groove 20 of the socket body 29. It is used to cooperate with the mounting groove 20 to realize the locking or unlocking operation of the relay 31 installed on the relay mounting position 30: by pushing the operating member 11, the sliding member 12 is driven to slide, so that the sliding member 12 presses against or disengages from the top surface of the relay 31, and the latching part 13 is engaged with the locking groove of the mounting groove 20 to complete the locking; pressing the operating member 11 drives the latching part 13 to deform and release the lock through the transmission part 14, which can meet the needs of stable fixation after the relay 31 is installed and subsequent disassembly.

[0062] Based on this, this embodiment also proposes a relay socket, including a socket body 29 and the aforementioned locking device for a relay socket. An assembly groove 20 is located near the top surface of the relay 31 and extends along the length of the slider 10 to the relay mounting position 30. The side wall of the assembly groove 20 is provided with a first locking groove 21 and a second locking groove 22 that cooperate with the buckle 15 of the buckle 13, thereby achieving locking at the corresponding position. The layout of the assembly groove 20 being located near the top surface of the relay 31 and extending to the mounting position 30 adapts to the sliding trajectory of the slider 10, ensuring that the slider 12 can accurately press against or disengage from the top surface of the relay 31, thus ensuring the effective realization of the locking and unlocking functions.

[0063] In this embodiment, the socket body 29 has two side plates 28 on the outer periphery of the relay mounting position 30 near the top surface of the relay 31. The side plates 28 form mounting grooves 20 with openings at the top. The mounting grooves 20 provide a stable sliding guide space for the slider 10 and also limit the slider 10. The side plates 28 are provided with a first locking groove 21 and a second locking groove 22 that extend along the width direction of the slider 10, adapting to the elastic deformation and snapping action of the buckle 13. The number of the first locking grooves 21 and the second locking grooves 22 corresponds to the buckle head 15 of the buckle 13. For a slider 12 with two buckles 13 and two buckles 15, the side plates 28 are respectively provided with the first locking grooves 21 and the second locking grooves 22. The top of the operating member 11 is exposed outside the opening of the mounting groove 20, improving the ease of operation.

[0064] The assembly groove 20 has two limiting blocks 23 spaced apart along the length of the slider 10 on the inner wall of the side plate 28 in the width direction of the slider 10. The two limiting blocks 23 are located at the top of the assembly groove 20 and extend towards the center in the width direction of the slider 10. That is, the limiting blocks 23 are protruding structures relative to the side wall of the assembly groove 20, and the opposite sides of the two limiting blocks 23 form limiting surfaces 24. The operating member 11 has a protrusion 19 on the opposite side of the side wall. When the slider 10 is locked in the corresponding position, the protrusion 19 abuts against the limiting surfaces 24 of the two limiting blocks 23.

[0065] In this embodiment, two limiting blocks 23 are respectively provided on the top of the two side plates 28. The limiting blocks 23 on the two side plates 28 are symmetrically distributed, which does not interfere with the deformation action of the slider 10 along the width direction, and the limiting blocks 23 are located above the transmission part 14. The abutting cooperation between the protrusion 19 and the limiting block 23 can limit the sliding stroke of the slider 10 along the length direction, avoid the slider 10 from being pushed too much and causing the buckle 13 to be misaligned with the locking groove, and ensure that the slider 10 stays at the target position.

[0066] Furthermore, the two limiting blocks 23 on the side plate 28 are respectively close to both ends of the slider 10 in the length direction. The mounting groove 20 has a mounting opening 27 at the end of the slider 10 away from the relay 31 in the length direction. The mounting opening 27 is used for the slider 10 to be installed. The limiting block 23 near the mounting opening 27 is provided with a third inclined surface 25, which is located on the side of the limiting block 23 opposite to the mounting opening 27. The protrusion 19 has a fourth inclined surface 26 on the side of the slider 10 facing the relay 31 in the length direction.

[0067] In this embodiment, when the slider 10 is inserted into the assembly groove 20 from the mounting port 27, the fourth inclined surface 26 and the third inclined surface 25 contact and cooperate, causing the operating member 11 to deform in the pressing direction. The protrusion 19 can smoothly pass over the limiting block 23 and enter the assembly groove 20. Then the operating member 11 is reset, and the protrusion 19 abuts against the limiting surface 24 of the limiting block 23. At the same time, the guide inclined surface 16 of the buckle 15 contacts the end face of the side plate 28 near the mounting port 27, forcing the buckle 13 to deform inward. After the slider 10 is fully inserted, the buckle 13 elastically resets, and the buckle 15 cooperates with the first locking groove 21 on the side plate 28. The slider 10 is installed in place and is in the unlocking relay 31 position.

[0068] After the relay 31 is installed in the relay mounting position 30 of the socket body 29, the slider 10 is initially in the unlocked position (the buckle 15 is engaged in the first locking groove 21, and the slider 12 is disengaged from the top surface of the relay 31). Pushing the operating member 11 towards the relay 31 causes the operating member 11 to move the slider 12 along the length of the mounting groove 20. During this movement, the guide slope 16 of the buckle 15 remains in contact with the groove wall of the first locking groove 21, forcing the two buckle portions 13 to elastically deform towards the center of the slider 10, ensuring smooth movement of the slider 12; simultaneously, the protrusions 19 on the operating member 11 slide synchronously along the intervals between the limiting blocks 23. When the slider 12 moves to partially press against the top surface of the relay 31, the buckle 15 is just aligned with the second locking groove 22 on the side wall of the assembly groove 20. The buckle 13 loses the pressure from the side wall and elastically resets. The buckle 15 is engaged in the second locking groove 22 to achieve positioning. At this time, the protrusion 19 on the operating member 11 simultaneously abuts against the limiting surface 24 of the limiting block 23 near the relay 31, restricting the slider 10 from continuing to slide. The double positioning ensures that the slider 10 is stably in this position. The slider 12 presses against the top surface of the relay 31 to complete the locking of the relay 31.

[0069] When it is necessary to disassemble the relay 31, press the suspended end of the operating member 11 into the assembly groove 20. The operating member 11 undergoes elastic deformation and drives the two transmission parts 14 on both sides to move down synchronously. The second inclined surface 18 at the end of the transmission part 14 contacts and engages with the first inclined surface 17 on the outer side of the buckle 13, converting the pressing force into a component force along the width direction of the slider 10, driving the two buckles 13 to elastically deform towards the center. The buckle head 15 disengages from the second locking groove 22, releasing the locking and positioning. While maintaining the pressing state, push the operating member 11 away from the relay 31, causing the sliding member 12 to slide in the opposite direction along the assembly groove 20. The sliding member 12 gradually disengages from the top surface of the relay 31. When the slider 12 is completely removed from the top surface of the relay 31, the buckle 15 aligns with the first locking groove 21. The pressing operation 11 is released, the force of the transmission part 14 on the buckle 13 disappears, the buckle 13 elastically resets, and the buckle 15 is inserted into the first locking groove 21. At this time, the protrusion 19 abuts against the limiting surface 24 of the limiting block 23 near the mounting port 27, and the slider 10 is stably in this position, completing the unlocking of the relay 31. The relay 31 can then be directly removed.
