In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0057] This embodiment provides a relay socket, which can achieve quick wiring without the aid of tools, is simple to operate, and has high wiring efficiency.

[0058] Specifically, Figure 1-Figure 5 As shown, the relay socket includes a housing 100 , a conductive plate 200 , an elastic member 300 and a push rod 400 .

[0059] The housing 100 is provided with a wiring cavity 111 connected to the outside, and the external wire 10 can extend into the wiring cavity 111. Optionally, in this embodiment, the wiring cavity 111 is connected to the outside through a wiring hole 112, and the external wire 10 can penetrate into the wiring cavity 111 through the wiring hole 112 for wiring.

[0060] One end of the conductive plate 200 is installed in the wiring cavity 111 for electrically connecting to the external wire 10, and the other end of the conductive plate 200 is used to connect to the control circuit 500 or the load circuit 600 of the relay socket. It is worth noting that the conductive plate 200 is a bridge for connecting the external wire 10 with the control circuit 500 or the load circuit 600 inside the relay socket. Since some external wires 10 need to be electrically connected to the control circuit 500, and some external wires 10 need to be electrically connected to the load circuit 600, therefore, generally, a plurality of wiring cavities 111 are provided in the housing 100 for realizing the electrical connection between the control circuit 500 and the load circuit 600 and the external wire 10.

[0061] One end of the elastic member 300 is fixed in the wiring cavity 111 , and the other end has a first position for inserting the external wire 10 between the elastic member 300 and the conductive plate 200 and a second position for pressing the external wire 10 against the conductive plate 200 .

[0062] One end of the push rod 400 is rotatably installed in the wiring cavity 111, the part of the push rod 400 placed in the wiring cavity 111 is connected to the elastic member 300, and the other end of the push rod 400 is placed outside the wiring cavity 111, and can drive the other end of the elastic member 300 to move from the second position to the first position under the driving of external force.

[0063] The specific steps of installing and removing the external wire 10 of the relay socket are as follows:

[0064] When wiring, the operator can manually drive the push rod 400 placed outside the housing 100 to rotate the push rod 400. The rotation of the push rod 400 will drive the elastic member 300 connected thereto to overcome its own elastic force and move in a direction away from the conductive plate 200, that is, the elastic member 300 is moved to the first position, and then the external wire 10 is inserted between the elastic member 300 and the conductive plate 200 through the wiring hole 112. After that, the push rod 400 is released, and the elastic member 300 will move from the first position to the second position under the action of its own elastic restoring force, pressing the external wire 10 against the conductive plate 200 to complete the wiring.

[0065] When removing the wires, the operator can manually drive the push rod 400 that is placed outside the housing 100 to rotate the push rod 400. The rotation of the push rod 400 will drive the elastic member 300 connected thereto to overcome its own elastic force and move in a direction away from the conductive plate 200, that is, the elastic member 300 is moved to the first position, and then the external wire 10 is pulled out. After that, the push rod 400 is released, and the elastic member 300 moves from the first position to the second position under the action of its own elastic restoring force, thereby completing the wire removal.

[0066] The relay socket can realize the quick plug-in connection of soft and hard wires without the aid of tools by arranging the cooperation between the elastic member 300 and the push rod 400, and the operation is simple and the wiring efficiency is high.

[0067] It is worth noting that before the relay is connected to the external wire 10, the other end of the elastic member 300 can be pressed against the conductive plate 200 or there is a small gap between the elastic member 300 and the conductive plate 200 in the absence of external force, but the distance from the conductive plate 200 cannot be too large, so as to ensure that after the external wire 10 is connected, the other end of the elastic member 300 can reliably press the external wire 10 against the conductive plate 200, thereby achieving a reliable electrical connection between the external wire 10 and the conductive plate 200.

[0068] Optionally, continue to see Figure 1 and Figure 2 In this embodiment, the housing 100 includes a base 110 and a top cover 120 , and the base 110 and the top cover 120 are snap-fitted and connected to form a wiring cavity 111 .

[0069] Optionally, continue to see Figure 3-Figure 5 The wiring cavity 111 is provided with a fan-shaped groove 1111, and the part of the push rod 400 placed in the wiring cavity 111 is installed in the fan-shaped groove 1111 and can abut against the groove wall of the fan-shaped groove 1111. A connecting hole 1112 is provided at the central angle of the fan-shaped groove 1111, and a rotating shaft 411 that rotatably cooperates with the connecting hole 1112 is provided at the end of one end of the push rod 400. As shown in the figure, the part of the push rod 400 placed in the wiring cavity 111 will rotate with the center of the fan-shaped groove 1111 as the rotation center, and the rotation angle of the push rod 400 can be limited by the groove wall of the fan-shaped groove 1111. On the one hand, it can prevent the push rod 400 from rotating too much in the direction away from the conductive plate 200, causing the deformation of the elastic member 300 to exceed the bearing limit, thereby protecting the elastic member 300 to a certain extent; on the other hand, it can also prevent the push rod 400 from rotating too much in the direction close to the conductive plate 200 due to accidental touching, resulting in excessive pressure of the elastic member 300 on the external wire 10 or the conductive plate 200, causing damage to the external wire 10 or the conductive plate 200.

[0070] Furthermore, in this embodiment, the push rod 400 includes a linkage portion 410 disposed in the wiring cavity 111 , so the linkage portion 410 is installed in the fan-shaped groove 1111 , and the rotating shaft 411 is disposed at one end of the linkage portion 410 .

[0071] It is understandable that the connection holes 1112 can be provided on both the base 110 and the top cover 120, and the rotating shafts 411 can be provided at the opposite ends of the linkage part 410, and the two rotating shafts 411 are rotatably connected to the corresponding connection holes 1112 on the base 110 and the top cover 120. In this way, the linkage part 410 is connected to the base 110 and the top cover 120 at the same time, thereby improving the stability of the installation of the linkage part 410.

[0072] Alternatively, if Figure 4-Figure 6 As shown, connecting arms 412 are provided on opposite sides of the linkage part 410 in the width direction, and the two connecting arms 412 can be elastically moved closer or farther away, and the two connecting arms 412 are used to be clamped with the elastic member 300. The connection between the linkage part 410 and the elastic member 300 is achieved by clamping, which ensures reliable connection and is convenient for installation and disassembly. At the same time, the setting of the connecting arms 412 can also improve the structural strength of the linkage part 410, thereby extending the service life of the push rod 400.

[0073] It can be understood that the width direction of the linkage portion 410 is the same as the thickness direction of the housing 100 .

[0074] Further, see Figure 3-Figure 6 On the housing 100, a first arc surface 130 is provided at the outer edge of the wiring cavity 111. The push rod 400 includes a toggle portion 420 disposed outside the housing 100, the bottom surface of the toggle portion 420 is a second arc surface 421 concave upward, and the second arc surface 421 is slidably attached to the first arc surface 130. Through the cooperation between the first arc surface 130 and the second arc surface 421, the rotation angle of the push rod 400 can be limited, thereby improving the smoothness and reliability of the rotation of the push rod 400, and further improving the reliability of the work of the push rod 400 driving the elastic member 300 to move to the first position.

[0075] Optionally, continue to see Figure 4-Figure 6 The push rod 400 includes a toggle portion 420 disposed outside the housing 100, and a toggle hook 422 is provided on the side of the toggle portion 420 facing away from the housing 100, and the toggle hook 422 is used to be driven by an external force. By providing the toggle hook 422, it is possible to prevent an operator from operating the toggle portion 420, that is, the friction between the operator's hand and the toggle portion 420 is increased, and the risk of slipping when operating the toggle portion 420 is reduced, thereby reducing the difficulty of operating the toggle portion 420.

[0076] Optionally, continue to see Figure 3-Figure 5 A limiting groove 1113 is provided in the wiring cavity 111, one end of the elastic member 300 is bent to form a limiting portion 310, the limiting portion 310 is installed in the limiting groove 1113, and the other end of the elastic member 300 is bent toward the conductive plate 200 to form a pressing portion 320, and the pressing portion 320 is used to press the external wire 10 against the conductive plate 200.

[0077] The elastic member 300 has a simple structure and can be made by bending, which is easy to process. The elastic member 300 is fixed by the cooperation between the limiting portion 310 and the limiting groove 1113, and the structure is reliable and easy to install and disassemble. The external wire 10 is pressed by the pressing portion 320, which can improve the reliability of the elastic member 300 fixing the external wire 10.

[0078] Further, see Figure 3-Figure 5 The housing 100 is also provided with a positioning cavity 140 that connects the wiring cavity 111 and the interior of the housing 100. One end of the conductive plate 200 extends from the positioning cavity 140 into the wiring cavity 111 and is bent upward to be attached to the inner wall of the wiring cavity 111. In this way, the conductive plate 200 can be positioned by bending the positioning cavity 140 and the conductive plate 200, thereby improving the stability of the installation of the conductive plate 200. The structure is simple, and the installation of the conductive plate 200 is convenient.

[0079] Alternatively, if Figure 7 As shown, in this embodiment, the conductive plate 200 includes a first contact portion 210 for electrically connecting to the external wire 10, a second contact portion 230 for electrically connecting to the control circuit 500 or the load circuit 600, and a positioning portion 220 connecting the first contact portion 210 and the second contact portion 230. The first contact portion 210 is attached to the inner wall of the wiring cavity 111, and the first contact portion 210 is positioned by the inner wall of the wiring cavity 111. The positioning portion 220 is installed in the positioning cavity 140 and is positioned by the positioning cavity 140. The second contact portion 230 extends into the interior of the housing 100 and is used to be electrically connected to the corresponding control circuit 500 or the load circuit 600. The conductive plate 200 has a simple structure and is easy to process.

[0080] Further, see Figure 3-Figure 5 A limiting protrusion 1114 is provided on the inner wall of the wiring cavity 111, and the limiting protrusion 1114 abuts against the top of the conductive plate 200. By providing the limiting protrusion 1114, the conductive plate 200 can be limited to ensure that the conductive plate 200 can be reliably attached to the inner wall of the wiring cavity 111.

[0089] Furthermore, if Figure 11-13 As shown, the housing 100 is provided with a mounting groove 160 for fixing the relay, an operating rod 800 for ejecting the relay is rotatably installed in the housing 100, a first elastic limiting portion 810 and a second elastic limiting portion 820 are provided on the operating rod 800, and the housing 100 is provided with a first matching limiting portion 170 matching with the first elastic limiting portion 810, and a second matching limiting portion 180 matching with the second elastic limiting portion 820.

[0090] Specifically, the first elastic limiting portion 810 and the first matching limiting portion 170 have a first matching state and a second matching state, and the operating rod 800 rotates to enable the first elastic limiting portion 810 and the first matching limiting portion 170 to switch between the first matching state and the second matching state.

[0091] In the first mating state, one end of the operating rod 800 passes through the bottom of the mounting groove 160 and lifts up the relay. In the second mating state, one end of the operating rod 800 is placed in the housing 100. In the process of the first elastic limiting portion 810 and the first mating limiting portion 170 switching from the second mating state to the first mating state, the second elastic limiting portion 820 presses against the second mating limiting portion 180 and undergoes elastic deformation.

[0092] The specific working process of the operating lever 800 is as follows:

[0093] When there is no need to eject the relay, the first elastic limiting portion 810 and the first matching limiting portion 170 are in the second matching state, and the second elastic limiting portion 820 is away from the second matching limiting portion 180 .

[0094] When the relay needs to be ejected, the operating rod 800 is rotated, and the first elastic limiting portion 810 will be elastically deformed under the action of the rotational force, so that the first elastic limiting portion 810 and the first matching limiting portion 170 are switched from the second matching state to the first matching state. In this process, the second elastic limiting portion 820 will contact the second matching limiting portion 180, and as the operating rod 800 is rotated, it will be pressed against the second matching limiting portion 180 and elastically deformed to buffer the rotation of the operating rod 800.

[0095] The operating rod 800 is provided with a first elastic limiting portion 810 and a second elastic limiting portion 820 so that during the process of ejecting the relay, the first elastic limiting portion 810 and the second elastic limiting portion 820 can buffer the force driving the operating rod 800 to rotate through elastic deformation, so that the relay can be ejected slowly, which is beneficial to protecting the relay.

[0096] Optionally, continue to see Figure 11-13 In this embodiment, a notch 830 can be opened on the operating rod 800. The setting of the notch 830 allows a part of the operating rod 800 to be elastically moved closer to or farther from the rest of the operating rod, thereby forming a second elastic limiting portion 820. Such a setting has a simple structure and is easy to process.

[0097] Furthermore, if Fig. 9 , Fig.14 and Fig.15 As shown, two spaced-apart limiting structures 150 are provided at the bottom of the base 110 , and a slide groove 101 that cooperates with the mounting rail of the relay socket is formed between the two limiting structures 150 .

[0098] At least one limiting structure 150 includes an elastic fence 151, and the elastic fence 151 and the bottom of the base 110 form a hollow hole 152. In the hollow hole 152, a first stop groove 153 close to the slide groove 101 and a second stop groove 154 away from the slide groove 101 are provided on the elastic fence 151. The top cover 120 is snap-fitted with the base 110, and a stop protrusion 122 is provided on the top cover 120. The stop protrusion 122 is installed in the hollow hole 152 and can be snapped into the first stop groove 153 and the second stop groove 154.

[0099] The specific steps for installing the relay socket on the mounting rail are:

[0100] Before installation, bend the elastic fence 151 in the direction away from the slide groove 101 so that the stopping protrusion 122 is engaged with the first stopping groove 153. At this time, the slide groove 101 between the two limiting structures 150 is larger, which is convenient for the connection between the slide groove 101 and the mounting guide rail. After the relay socket is installed in a suitable position on the mounting guide rail, push the elastic fence 151 in the direction close to the slide groove 101 so that the stopping protrusion 122 is engaged with the second stopping groove 154. At this time, the slide groove 101 between the two limiting structures 150 becomes smaller, which enables the limiting structure 150 to firmly clamp the mounting guide rail, and through the cooperation of the stopping protrusion 122 and the second stopping groove 154, the limiting structure 150 can always maintain reliable clamping of the mounting guide rail, thereby improving the reliability of the connection between the relay socket and the mounting guide rail.
