[0051] As Figures 1 to 4 shown, this embodiment provides a relay socket, which includes a base assembly 1, a spring piece assembly 2, and an elastic adjustment assembly 3. The spring piece assembly 2 includes a first clip 21 and a second clip 22. The first end of the first clip 21 is fixedly connected to the base assembly 1, the first end of the second clip 22 is connected to the first clip 21, and the second end of the second clip 22 is spaced from the second end of the first clip 21 and is used for clamping the lead of the relay. The elastic adjustment assembly 3 includes a toggling member 31, an adjusting member 32, and a locking member 33. The adjusting member 32 is arranged inside the base assembly 1. The first end of the toggling member 31 penetrates the base assembly 1 and is connected to the adjusting member 32, and the second end of the toggling member 31 is placed outside the base assembly 1 and is connected to the locking member 33. When the second end of the toggling member 31 rotates from the initial position to the locking position, the toggling member 31 drives the adjusting member 32 to rotate and presses the second clip 22, so that the distance between the second end of the second clip 22 and the second end of the first clip 21 is reduced, and the locking member 33 is locked to the base assembly 1.

[0052] In the relay socket provided in the present embodiment, the second end of the second clip 22 of the spring sheet assembly 2 and the second end of the first clip 21 are used to clamp the lead-out pin of the relay. After the relay and the relay socket are plugged in and out for many times, the spring sheet assembly 2 has metal elastic fatigue, and the distance between the second end of the first clip 21 and the second end of the second clip 22 becomes larger. When the first clip 21 and the second clip 22 cannot clamp the lead-out pin of the relay, the second end of the toggle member 31 is rotated, and the adjusting member 32 is linked with the toggle member 31 to make the adjusting member 32 press against the second clip 22, and the distance between the second end of the second clip 22 and the second end of the first clip 21 is reduced, so that the first clip 21 The second clamping piece 22 can clamp the lead-out pin of the relay, ensure the stability of the connection between the relay and the relay socket, and extend the service life of the relay socket. The second end of the toggle member for the operator to operate is placed on the outside of the base assembly 1. There is no need to disassemble the base assembly 1 during adjustment, which is convenient for the operator to adjust. In addition, when the toggle member 31 is rotated from the initial position to the locked position, the locking member 33 is linked with the toggle member 31. When the toggle member 31 is rotated, the locking connection between the locking member 33 and the base assembly 1 is realized, which prevents the toggle member 31 from rotating during use. The locking member 33 and the toggle member 31 have strong linkage, simple operation, and are easy to implement.

[0053] The base assembly 1 is provided with a receiving groove 11, and the adjusting member 32 is arranged in the receiving groove 11. Optionally, the base assembly 1 includes a base 17, a shell 18 and an insulating block 19, the spring sheet assembly 2 is arranged on the insulating block 19, and the receiving groove 11 is arranged on the insulating block 19. The insulating block 19 is mounted on the base 17, and the shell 18 is covered on the outside of the insulating block 19 and connected to the base 17. Specifically, the insulating block 19 is provided with a spring sheet placement groove 191, and the spring sheet placement groove 191 is used to place the spring sheet assembly 2, and the first end of the first clamp 21 is fixedly connected to the spring sheet placement groove 191. According to usage requirements, multiple spring sheet placement grooves 191 are provided, and the multiple spring sheet placement grooves 191 are arranged into multiple columns, and each column is provided with multiple spring sheet placement grooves 191 at intervals. The second clips 22 in two adjacent columns of spring sheet placement grooves 191 are arranged closely, and a receiving groove 11 can be provided between the two columns of spring sheet placement grooves 191. The receiving groove 11 is connected to the spring sheet placement groove 191, and the adjusting member 32 is provided in the receiving groove 11, and the adjusting member 32 can contact with the second clip 22 and can squeeze the second clip 22. By providing an adjusting member 32, the spacing between multiple second clips 22 and the corresponding first clip 21 can be adjusted at the same time, thereby simplifying the structure of the elastic adjustment component 3, and the adjustment of the spacing between the first clip 21 and the second clip 22 is consistent. The upper surface of the housing 18 is provided with a plug hole 181 , which is arranged corresponding to the gap between the first clip 21 and the second clip 22 . The lead pin of the relay passes through the plug hole 181 and is clamped between the first clip 21 and the second clip 22 .

[0054] In some embodiments, Figures 3 to 5 As shown, the adjusting member 32 includes a first adjusting rod 321, and the two ends of the first adjusting rod 321 are coaxially connected to the second adjusting rod 322, one of the second adjusting rods 322 is connected to the first end of the toggle member 31, and the other second adjusting rod 322 is rotatably connected to the base assembly 1. Optionally, the second adjusting rod 322 is rotatably connected to the groove wall of the above-mentioned accommodating groove 11. The first adjusting rod 321 includes a first rod portion 3211, the first rod portion 3211 is elliptical, and the second rod portion 3212 is provided in the middle of one side of the first rod portion 3211 along the short axis direction, and the second rod portion 3212 is smoothly transitionally connected to the first rod portion 3211. When the toggle member 31 is placed in the initial position, the second rod 3212 is placed below the first rod 3211 in the short axis direction, and the end of the first rod 3211 along the long axis direction contacts the first position of the second clip 22; when the toggle member 31 is placed in the locking position, the second rod 3212 is placed above the first rod 3211 in the short axis direction, and the end of the first rod 3211 along the long axis direction presses the second position of the second clip 22, and the second position is placed below the first position along the short axis direction. By rotating the adjustment member 32, the end of the first adjustment rod 321 along the long axis direction contacts different positions of the second clip 22, thereby realizing the adjustment of the spacing between the second clip 22 and the first clip 21, and the structure of the adjustment member 32 is simple. The second end of the first clamp 21 and the second end of the second clamp 22 are combined into an X shape, and the spacing between the second clamp 22 and the end of the first adjustment rod 321 along the long axis direction is different. The first adjustment rod 321 contacts the first position of the second clamp 22, and the first adjustment rod 321 presses against the second position of the second clamp 22.

[0055] In some other embodiments, the adjusting member includes a first rod portion, the first rod portion is a circular rod, and the first rod portion is symmetrically provided with a first ridge and a second ridge relative to the center of the circle, and the first ridge and the second ridge are used to contact the second clip 22, or the first ridge and the second ridge are used to squeeze the second clip 22. In order to ensure smooth rotation of the adjusting member, the surfaces of the first ridge and the second ridge are both in arc shape.

[0056] like Figure 2 , Figure 4 and Figure 6As shown, in order to realize that the toggle member 31 drives the adjusting member 32 to rotate, the toggle member 31 needs to be rotatable relative to the base assembly 1, and the base assembly 1 provides support for the installation of the toggle member 31. Optionally, a mounting hole 12 is provided on the groove wall of the accommodating groove 11, and the toggle member 31 includes a toggle block 313. A plurality of clamping plates 314 are provided on one side of the toggle block 313 along the circumference of the toggle block 313. A clamping block 315 is provided at the end of the clamping plate 314. The clamping plate 314 is elastically deformed to penetrate the mounting hole 12. The clamping block 315 is against the groove wall of the accommodating groove 11, and the locking member 33 is in contact with the outer wall of the base assembly 1. The locking member 33 cooperates with the clamping block 315 to enable the toggle member 31 to be rotatably arranged on the base assembly 1. When installing, a second adjusting rod 322 of the adjusting member 32 is connected to one side of the toggle block 313 provided with a clamping plate 314, and the clamping plate 314 is arranged around the second adjusting rod 322. A sleeve is provided on the groove wall opposite to the mounting hole 12 in the accommodating groove 11, and the sleeve is coaxially arranged with the mounting hole 12. The two second adjusting rods 322 and the first adjusting rod 321 are successively passed through the mounting holes 12, and the clamping block 315 abuts against the hole wall of the mounting hole 12. The hole wall of the mounting hole 12 squeezes the clamping block 315 to make the clamping plate 314 shrink inwardly. When the clamping block 315 passes through the mounting hole 12, the clamping plate 314 is reset, and the clamping block 315 abuts against the groove wall of the accommodating groove 11. The second adjusting rod 322 arranged opposite to the clamping block 315 is inserted into the sleeve, thereby realizing the installation of the adjusting member 32 and the toggle member 31.

[0057] In some other embodiments, the toggle member includes a toggle block with a T-shaped structure, a small end of the toggle block is provided with an elastic block protruding along the circumferential direction, a second adjustment rod 322 of the adjustment member 32 is connected to the end surface of the small end of the toggle block, the outer diameter of the elastic block is larger than the aperture of the mounting hole 12, the elastic block can be squeezed over the mounting hole 12, and the elastic block cooperates with the locking member 33 to enable the toggle member to be rotatably arranged on the base assembly 1. The elastic block can be made of rubber material, which is not specifically limited here.

[0058] In some embodiments, Figure 7 and Figure 8As shown, the locking member 33 includes a lever 331 and a clamping member 332. The lever 331 and the clamping member 332 are arranged on opposite sides of the toggling member 31. The outer sidewall of the base assembly 1 is provided with a first limiting portion 4 and a second limiting portion 5 along the long axis direction. The second end of the toggling member 31 is placed between the first limiting portion 4 and the second limiting portion 5. When the toggling member 31 is in the initial position, the toggling member 31 abuts against the first limiting portion 4, and the clamping member 332 abuts against the second limiting portion 5. When the toggling member 31 rotates from the initial position to the locking position, both the lever 331 and the clamping member 332 rotate around the first direction. The clamping member 332 is squeezed by the second limiting portion 5 and crosses over the second limiting portion 5. When the toggling member 31 rotates to the locking position, the clamping member 332 is squeezed by the first limiting portion 4 and crosses over the first limiting portion 4. The clamping member 332 abuts against the first limiting portion 4 around the second direction, and the lever 331 abuts against the second limiting portion 5 around the first direction. When the distance between the second ends of the first clamping piece 21 and the second clamping piece 22 becomes larger, the lever 331 is toggled around the first direction, the toggling member 31 rotates, the adjusting member 32 rotates along with the toggling member 31, and the adjusting member 32 squeezes the second clamping piece 22. When the toggling member 31 rotates to the locking position, the clamping member 332 is blocked by the first limiting portion 4 around the second direction, and the lever 331 is blocked by the second limiting portion 5 around the first direction. Thus, the locking connection between the locking member 33 and the base assembly 1 is realized. The lever 331 cannot rotate around the second direction, and the clamping member 332 cannot rotate around the first direction, preventing the toggling member 31 from rotating during use. The locking member 33 and the toggling member 31 have strong linkage, simple operation, and are easy to implement. Figure 8 The locking member 33 on the left in is in a locked state with the base assembly 1. Figure 8 The locking member 33 on the right in is in an unlocked state with the base assembly 1.

[0059] Optionally, the snap member 332 includes an elastic arm 3321. The first end of the elastic arm 3321 is elastically connected to the toggle member 31. The second end of the elastic arm 3321 is provided with a snap block 3322. When the toggle member 31 is in the initial position, the snap block 3322 abuts against the second limiting portion 5. When the snap member 332 rotates in the first direction, the second limiting portion 5 is used to squeeze the snap block 3322 to elastically deform the elastic arm 3321, so that the snap block 3322 passes over the second limiting portion 5, or the first limiting portion 4 squeezes the snap block 3322 to elastically deform the elastic arm 3321, and the snap block 3322 passes over the first limiting portion 4 and abuts against the first limiting portion 4. The snap block 3322 may be a structure with an arc surface. The arc surface of the snap block 3322 contacts the first limiting portion 4 or the second limiting portion 5, so that the snap block 3322 can smoothly pass over the second limiting portion 5 or the first limiting portion 4. When passing over the first limiting portion 4, the elastic arm 3321 resets, so that the snap block 3322 abuts against the first limiting portion 4. The snap block 3322 may also be a right triangle structure. The inclined surface of the snap block 3322 is used to contact the second limiting portion 5 or the first limiting portion 4. The first limiting portion 4 or the second limiting portion 5 squeezes the snap block 3322, and the elastic arm 3321 deforms, so that the snap block 3322 can pass over the first limiting portion 4 or the second limiting portion 5. After passing over the first limiting portion 4, the right-angle side of the snap block 3322 abuts against the first limiting portion 4.

[0060] Further optionally, the toggle member 31 is connected with a support arm 311. The support arm 311 and the elastic arm 3321 both extend along the long axis direction. The elastic arm 3321 is a wavy structure. A connecting arm 312 is connected between the second end of the elastic arm 3321 and the support arm 311, and the connecting arm 312 is elastically connected to the support arm 311. The setting of the support arm 311 provides support for the elastic arm 3321. When the snap block 3322 is squeezed, it avoids the elastic arm 3321 being squeezed and bent, so that the snap block 3322 cannot smoothly pass over the second limiting portion 5 or the first limiting portion 4. The elastic arm 3321 is a wavy structure, and the elastic arm 3321 can be elastically compressed.

[0061] In some other embodiments, the elastic arm is a plate-like structure. The first end of the elastic arm is elastically connected to the toggle member 31. The elastic arm extends along the short axis direction. The second end of the elastic arm is provided with a snap block. As the toggle member 31 is rotated, the snap block is squeezed by the second limiting portion 5 or the first limiting portion 4, and the side of the elastic arm facing the toggle member 31 elastically deforms, so that the snap block passes over the second limiting portion 5 or the first limiting portion 4.

[0062] In some embodiments, the outer wall of the base assembly 1 is provided with a semicircular first guide plate 6, the first guide plate 6 and the outer wall of the base assembly 1 are surrounded to form a semicircular first groove 61, the first end of the first guide plate 6 is connected to the first end of the first limiting portion 4, the second end of the first guide plate 6 is connected to the first end of the second limiting portion 5, the second end of the first limiting portion 4 and the second end of the second limiting portion 5 are both toward the outside of the first groove 61 and extend along the long axis direction, the rotation axis of the toggle member 31 is colinear with the center of the first groove 61, when the clamping block 3322 passes over the second limiting portion 5, the groove wall of the first groove 61 presses the clamping block 3322. When the clamping block 3322 passes over the first limiting portion 4, the clamping block 3322 is no longer squeezed, the elastic arm 3321 is reset and popped open, and the clamping block 3322 presses against the first limiting portion 4. The first guide plate 6 provides a guide for the rotation of the clamping member 332 to prevent the toggle member 31 from shaking during the rotation, thereby ensuring the stability of the adjusting member 32 when squeezing the second clamping piece 22 .

[0063] Further optionally, the outer side wall of the base assembly 1 is provided with a semicircular second guide plate 7, the second guide plate 7 and the outer side wall of the base assembly 1 are surrounded to form a semicircular second groove 71, the diameter of the second groove 71 is greater than the diameter of the first groove 61, the first end of the second guide plate 7 is connected to the second end of the first limit portion 4, the second end of the second guide plate 7 is connected to the second end of the second limit portion 5, when the toggle member 31 rotates from the initial position to the locking position, the lever 331 rotates in the second groove 71 around the first direction. The setting of the second guide plate 7 provides a guide for the rotation of the lever 331, avoids the shaking of the toggle member 31 during the rotation process, and ensures the stability of the adjusting member 32 when squeezing the second clip 22. In addition, the toggle member 31, the lever 331 and the clamping member 332 are placed in the second groove 71 to prevent the toggle member 31 or the lever 331 from being accidentally touched, which plays a protective role and also improves the overall aesthetics of the relay socket.

[0064] The first limiting portion 4 and the second limiting portion 5 can be limiting plates extending from the end of the first guide plate 6, or can be limiting plates extending from the end of the second guide plate 7. The first limiting portion 4 and the second limiting portion 5 connect the first guide plate 6 and the second guide plate 7, and connect the first groove 61 and the second groove 71 to form a circumferentially closed groove body. The side surface of the limiting plate facing the second groove 71 is used to contact the clamping block 3322.

[0065] The relay is plugged into the relay socket, and the lead pin of the relay is clamped between the first clip 21 and the second clip 22. The relay socket with the relay plugged in is connected to the circuit. The relay socket needs to be provided with a terminal for connecting to the external circuit. Each spring sheet assembly 2 is respectively provided with a terminal, so that the external circuit is electrically connected to the relay, and then the relay is connected to the circuit. Therefore, if Figure 9 andFigure 10 As shown, a wiring groove 13 is provided on the base assembly 1. An inlet hole 14 is provided on the side wall of the wiring groove 13. The inlet hole 14 is used for a power line to pass through and is placed in the wiring groove 13. A spring piece 8 and a driving member 9 are provided in the wiring groove 13. The driving member 9 and the spring piece 8 are respectively rotatably connected to the wiring groove 13. The first end of the driving member 9 is placed outside the wiring groove 13, and the second end of the driving member 9 is connected to the spring piece 8. The first end of the spring piece 8 is connected to the first end of the first clip 21 through a wire. The first end of the driving member 9 is used to be rotated so that the spring piece 8 rotates, and the second end of the spring piece 8 presses against or releases the wire in the wiring groove 13. This structure replaces the traditional structure of fixing the wire by screwing, which is convenient and fast. When wiring, the first end of the driving member 9 is toggled to rotate the driving member 9. The rotation of the driving member 9 causes the spring piece 8 to rotate, increasing the distance between the second end of the spring piece 8 and the bottom of the wiring groove 13 to facilitate the insertion of the wire into the wiring groove 13. After the wire is inserted into the wiring groove 13, the first end of the driving member 9 is toggled to rotate. The rotation direction is opposite to the rotation direction of the driving member 9 during wiring. The driving member 9 causes the spring piece 8 to rotate to reduce the distance between the second end of the spring piece 8 and the bottom of the wiring groove 13. The second end of the spring piece 8 presses against the wire in the wiring groove 13 to fix the wire in the wiring groove 13.

[0066] As Figure 9 、 Figure 10 and Figure 11 shown, the driving member 9 drives the spring piece 8 to rotate. Optionally, a hook block 91 and a pressing portion 92 are provided at the second end of the driving member 9. A clamping hole 81 is provided on the spring piece 8. The hook block 91 is slidably arranged in the clamping hole 81, and the pressing portion 92 presses against one side surface of the spring piece 8 where the clamping hole 81 is provided. When the first end of the driving member 9 is rotated from the first position to the second position, the hook block 91 slides in the clamping hole 81 and abuts against the other side surface of the spring piece 8. The driving member 9 drives the spring piece 8 to rotate through the hook block 91, so that the second end of the spring piece 8 releases the wire placed in the wiring groove 13. Exemplarily, taking Figure 9 as an example, for the driving member 9 placed on the left, when the first end of the driving member 9 is toggled upward, when the driving member 9 rotates from the first position around the second direction to the second position, the spring piece 8 rotates around the first direction to increase the distance between the second end of the spring piece 8 and the bottom of the wiring groove 13, thereby releasing the wire in the wiring groove 13. For the driving member 9 placed on the right, when the driving member 9 is toggled upward, when the driving member 9 rotates from the first position around the first direction to the second position, the spring piece 8 rotates around the second direction to increase the distance between the second end of the spring piece 8 and the bottom of the wiring groove 13, thereby releasing the wire in the wiring groove 13. When the first end of the driving member 9 is rotated from the second position to the first position, the hook block 91 slides in the clamping hole 81 and moves away from the other side surface of the spring piece 8. The pressing portion 92 presses the spring piece 8 to rotate the spring piece 8, and the second end of the spring piece 8 presses against the wire in the wiring groove 13. Exemplarily, taking Figure 9 ​For example, for the driving member 9 disposed on the left side, when the first end of the driving member 9 is toggled downward and the driving member 9 rotates from the second position to the first position around the first direction, the elastic piece 8 rotates around the second direction to reduce the distance between the second end of the elastic piece 8 and the bottom of the wiring groove 13, thereby pressing against the wire in the wiring groove 13. For the driving member 9 disposed on the right side, when the first end of the driving member 9 is toggled downward and the driving member 9 rotates from the second position to the first position around the second direction, the elastic piece 8 rotates around the first direction to reduce the distance between the second end of the elastic piece 8 and the bottom of the wiring groove 13, thereby pressing against the wire in the wiring groove 13.

[0067] The pressing portion 92 is a convex block provided on the end surface of the second end of the driving member 9. The surface of the convex block is an arc surface, and the convex block is smoothly connected to the driving member 9 in a smooth transition. The hook block 91 is connected to the arc surface of the convex block and is disposed in the middle of the arc surface. The rest of the arc surface presses against one side surface of the elastic piece 8 provided with the clamping hole 81. During the rotation of the driving member 9, the pressing portion 92 always presses against the elastic piece 8.

[0068] The driving member 9 is rotatably connected to the wiring groove 13. Optionally, a rotating shaft is provided on the groove wall of the wiring groove 13, and the driving member 9 is rotatably connected to the rotating shaft.

[0069] The elastic piece 8 is rotatably connected to the wiring groove 13. Optionally, the elastic piece 8 includes an L-shaped first plate 82 and a U-shaped second plate 83. The first end of the first plate 82 is connected to the first end of the second plate 83. The second end of the first plate 82 is connected to the wire. The second end of the second plate 83 is used to press against the wire. The clamping hole 81 is provided on the first plate 82 and extends along the length direction of the first plate 82. The pressing portion 92 presses against one side surface of the first end of the first plate 82. The hook block 91 can slide to the end of the clamping hole 81 close to the first end of the first plate 82, and the hook block 91 presses against the other side surface of the elastic piece 8 to facilitate applying a force to the elastic piece 8 to make the elastic piece 8 rotate. A positioning post 15 and a limiting block 16 are provided in the wiring groove 13. The middle of the second plate 83 is rotatably disposed between the positioning post 15 and the limiting block 16. The positioning post 15 and the limiting block 16 cooperate to position the elastic piece 8 and enable the elastic piece 8 to rotate.

[0070] Further optionally, the cross section of the positioning post 15 is rectangular, and the edges and corners of the rectangle can provide resistance to the rotation of the elastic piece 8, improving the feel of toggling the driving member 9. In the state where the second end of the elastic piece 8 releases the wire by toggling the first end of the driving member 9, the second end of the second plate 83 can contact the lower surface of the positioning post 15, that is, the lower surface of the positioning post 15 plays a role in limiting the rotation of the elastic piece 8, thereby limiting the rotation range of the driving member 9. In some other embodiments, the cross section of the positioning post 15 is circular, which is not specifically limited herein.

[0071] The surface of the limit block 16 facing the positioning column 15 is an arc-shaped surface, and the arc of the arc-shaped surface is greater than the arc of the second plate 83, so as to provide sufficient space for the rotation of the spring piece 8. When the first end of the driving member 9 is moved to make the second end of the spring piece 8 press against the wire, the second end of the second plate 83 can contact the arc-shaped surface of the limit block 16, that is, the arc-shaped surface plays a role in limiting the rotation of the spring piece 8, thereby limiting the rotation range of the driving member 9.
