[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] The following combination Figures 1 to 3 , describing embodiments of the present invention.

[0028] According to an embodiment of the present invention, a connector is provided, comprising: a main body 1, an electrical conductor 2, and a spring 3. A wiring cavity is constructed in the main body 1, and the main body 1 is provided with a wiring hole 4 connected to the wiring cavity. The electrical conductor 2 is fixedly arranged on the side wall of the wiring cavity, and the spring 3 is fixedly arranged in the wiring cavity. The spring 3 has a swing end 5 that cooperates with the conductive contact surface of the electrical conductor 2 to clamp the wire 10 extending from the wiring hole 4 into the wiring cavity. The swing end 5 and the conductive contact surface are constructed to form a wire clamping structure.

[0029] Specifically, a first buckle 6 is provided on the spring piece 3, and a movable button 7 is provided on the main body 1. The button 7 can be moved toward or away from the wiring cavity under external force. A second buckle 8 is provided on the button 7. When the button 7 moves to the specified position, the second buckle 8 is fastened and fixed with the first buckle 6. At the same time, one end of the button 7 abuts against the surface of the swing end 5 to swing it away from the conductive contact surface to open the wire clamping structure so that the wire 10 can be extended into the wiring cavity.

[0030] In this embodiment, Figure 1 and Figure 2 In the figure, the electrical conductor 2 is arranged on the left side wall of the wiring cavity, the conductive contact surface of the electrical conductor 2 faces the wiring cavity, the conductive contact surface is located on the right side of the electrical conductor 2, and the conductive contact surface is arranged in the wiring cavity. The spring piece 3 is arranged on the right side of the wiring cavity, one end of the spring piece 3 is a swing end 5, and the swing end 5 extends toward the conductive contact surface. The wiring hole 4 is arranged on the left side of the main body 1, and the wiring hole 4 is connected to the wiring cavity. The wire 10 can be inserted into the wiring cavity through the wiring hole 4 and contact the conductive contact surface. The button 7 is movably arranged on the right side of the wiring hole 4 and is located at the upper end of the spring piece 3. In the initial state, the end of the swing end 5 abuts the surface of the conductive contact surface, and the lower end of the button 7 lightly touches the surface of the swing end 5. At this time, the first buckle 6 and the second buckle 8 are in a disengaged state; when wiring is required, an external force drives the button 7 to move so that the lower end of the button 7 abuts the surface of the swing end 5. The button 7 pushes the swing end 5 to elastically deform and swing in a direction away from the conductive contact surface. When the button 7 moves to the specified position, the second buckle 8 of the button 7 is buckled and fixed with the first buckle 6 on the spring piece 3.

[0031] It should be noted that, by providing a first buckle 6 on the spring piece 3 and a second buckle 8 on the button 7, when the button 7 moves toward the wiring cavity, it will drive the swing end 5 to move in the direction away from the electrical conductor 2. When it moves to the specified position, the first buckle 6 and the second buckle 8 are engaged to fix the swing end 5, and the wire clamping structure is in an open state. At this time, the wire insertion work can be completed with one hand, and there is no need to use tools or continuously press the button 7 by hand to open the wire clamping structure. Furthermore, the connector of the present invention has a simple structure, simple operation, and is easy to use.

[0032] In some embodiments, the spring piece 3 is provided with an avoidance position 9 for accommodating the swing end 5 .

[0033] In this embodiment, Figures 1 to 3 In the figure, the avoidance position 9 is located on the right side of the swing end 5. When the button 7 moves to the specified position, the second buckle 8 of the button 7 is fastened and fixed with the first buckle 6 on the spring 3. At this time, the swing end 5 is just located in the avoidance position 9. The swing end 5 is fixed in the avoidance position 9 by the force of the button 7, thereby keeping the wire clamping structure in the open state.

[0034] It should be noted that by setting the avoidance position 9, when wiring is being carried out, the swing end 5 is driven by the button 7 to swing, and there will be no obstruction problem during the swinging process. The swing end 5 will not stop swinging until the first buckle 6 and the second buckle 8 are fastened and fixed. When the first buckle 6 and the second buckle 8 are fastened, the swing end 5 is just located in the avoidance position 9. At this time, the tension of the wire clamping structure is at its maximum, which can facilitate the wires 10 of different diameters to extend into the wiring cavity and contact the conductive contact surface.

[0035] In some embodiments, a movable unlocking structure 11 is further provided in the wiring cavity. One end of the wire 10 extending into the wiring cavity is connected to the unlocking structure 11 and drives the unlocking structure 11 to move in the extension direction of the wire 10. The movement of the unlocking structure 11 can provide a thrust to the first buckle 6 or the button 7 to disengage the first buckle 6 and the second buckle 8.

[0036] In this embodiment, if Figure 2 As shown, wire 10 extends from wiring hole 4 into the wiring cavity. After wire 10 extends to a certain depth, wire 10 drives unlocking structure 11 to move. Simultaneously, unlocking structure 11 drives first clip 6 toward the conductive contact surface, disengaging first clip 6 from second clip 8. Under the elastic force of swing end 5, button 7 moves away from the wiring cavity and resets. Driven by the elastic force, swing end 5 also resets and cooperates with the conductive contact surface to clamp wire 10, ensuring close contact between wire 10 and the conductive contact surface. The provision of unlocking structure 11 facilitates disengagement of first clip 6 from second clip 8, improving wiring efficiency.

[0037] In other optional embodiments, the wire 10 drives the unlocking structure 11 to move, and while the unlocking structure 11 moves, it drives the button 7 to move away from the first buckle 6 so that the first buckle 6 and the second buckle 8 are disengaged.

[0038] In some embodiments, the unlocking structure 11 includes a pushing arm 111 at one end and a connecting arm 112 at the other end. The pushing arm 111 in the initial state stops on the end of the wire 10 inserted into the wiring cavity through the wiring hole 4 to a set depth. The connecting arm 112 is connected to the first buckle 6. After the pushing arm 111 is subjected to the axial thrust of the wire 10 along the wiring hole 4, it drives the connecting arm 112 to move toward the direction close to the swing end 5. The pushing arm 111 can drive the first buckle 6 to move so that the first buckle 6 is disengaged from the second buckle 8. A first elastic reset member 12 is also provided in the wiring cavity. The first elastic reset member 12 is connected to the swing end 5 to provide an elastic retaining force for resetting the swing end 5.

[0039] In this embodiment, if Figure 2As shown, the left end of the unlocking structure 11 is a push arm 111, and the right end of the unlocking structure 11 is a connecting arm 112. The right side of the connecting arm 112 is connected to the second clip 8. The push arm 111 is set on the travel path of the wire 10. In the initial state, the push arm 111 is set horizontally and the connecting arm 112 is set vertically. When the wire 10 extends into the wiring cavity and abuts against the push arm 111, the wire 10 is driven by an external force to push the push arm 111 to move. At the same time, the push arm 111 drives the connecting arm 112 toward the conductive contact surface. The connecting arm drives the first clip 6 to move, thereby disengaging the first clip 6 from the second clip 8. The swing end 5 is installed in the wiring cavity so that it can swing back and forth. The first elastic return member 12 provides an elastic return force to the swing end 5 along its swinging direction.

[0040] In some embodiments, the first buckle 6 includes a swing arm 601 connected to the connecting arm 112 and a hook 602 fixed on both sides of the swing arm 601. The hook 602 cooperates with the second buckle 8. The hook 602 and the swing arm 601 are constructed into a U-shaped structure. The opening of the U-shaped structure faces the swing end 5, and the groove of the U-shaped structure is the avoidance position 9.

[0041] In this embodiment, if Figures 1 to 3 As shown, the left side of the swing arm 601 is connected to the connecting arm 112, and the hooks 602 are respectively arranged on opposite sides of the connecting arm 112. The two hooks 602 and the swing arm 601 are constructed to form a U-shaped structure in cross section. The open swing end 5 of the U-shaped structure and the groove of the U-shaped structure are the avoidance position 9. In the initial state, the two hooks 602 are arranged vertically. The lower end of the button 7 drives the swing end 5 to move, causing the swing end 5 to move into the avoidance position 9. At this time, the two hooks 602 are fixedly engaged with the second buckle 8, fixing the swing end 5 in the avoidance position 9. When the wire 10 inserted into the wiring cavity contacts the push arm 111 and pushes the push arm 111 to move, the connecting arm 112 drives the swing arm 601 to move, and the hooks 602 move with the swing arm 601, thereby achieving the effect of disengaging the hooks 602 from the second buckle 8. Driven by the elastic force, the swing end 5 extends from the avoidance position 9 and clamps the wire 10.

[0042] Specifically, the hook 602 faces the right side, and the second buckle 8 is arranged at the lower end of the left side of the button 7.

[0043] In some embodiments, a second elastic reset member 13 is further provided in the wiring cavity. The second elastic reset member 13 is connected to the swing arm 601 to provide an elastic retaining force for resetting the swing arm 601 .

[0044] In this embodiment, if Figures 1 to 3As shown, the unlocking structure 11 is installed in the wiring cavity and can swing back and forth in the arrangement direction of the pushing arm 111 and the connecting arm 112, and the first elastic return member 12 provides an elastic return force to the unlocking element along its swinging direction.

[0045] In some embodiments, the unlocking structure 11 is an L-shaped structure, one side wall of the unlocking structure 11 is a pushing arm 111, and the other side wall is a connecting arm 112. The swing arm 601 is an L-shaped structure, one side wall of the swing arm 601 is connected to the connecting arm 112, and the other side wall of the swing arm 601 is connected to the second elastic return member 13. The pushing arm 111, the connecting arm 112, the swing arm 601 and the second elastic return member 13 are constructed as an integrally formed structure.

[0046] In this embodiment, if Figures 1 to 3 As shown, the second elastic reset member 13 is an elastic cantilever structure, one end of which is fixedly positioned on the inner side wall, and the other end is fixedly connected to the swing arm 601 to form an integral structure. The second elastic reset member 13 is connected to the L-shaped structure of the swing arm 601 to form a step structure, so that the push arm 111, the connecting arm 112 and the swing arm 601 swing with the connection point between the swing arm 601 and the second elastic reset member 13 as the fulcrum. Preferably, the first elastic reset member 12 is also an elastic cantilever structure, and the swing end 5 swings with the connection point between the swing end 5 and the first elastic reset member 12 as the fulcrum. In addition to adopting a cantilever structure, the elastic reset member can also be a torsion spring, a compression spring or a tension spring. This is an equivalent replacement structure that can be easily thought of by those skilled in the art based on this application and falls within the scope of protection of this application.

[0047] Preferably, in this embodiment, the connecting arm 112 is connected to the swing arm 601 so that the pushing arm 111, the connecting arm 112 and the swing arm 601 form a step structure, and the pushing arm 111, the connecting arm 112, the swing arm 601 and the second elastic reset member 13 are integrally formed to form a cross-shaped structure.

[0048] In this embodiment, if Figures 1 to 3 As shown, the avoidance position 9 is arranged on the side of the swing end 5 away from the conductive contact surface. The swing end 5 is suitable for swinging in the direction away from the conductive contact surface and toward the avoidance position 9 under the drive of the button 7. When the second buckle 8 is fastened with the first buckle 6, the swing end 5 is located in the avoidance position 9 to expand the wire clamping structure.

[0049] In some embodiments, a button channel 14 communicating with the wiring cavity is provided on the main body 1 , and the button 7 is provided in the button channel 14 to reciprocate along the button channel 14 toward or away from the wiring cavity.

[0050] In this embodiment, if Figure 1 and Figure 2As shown, the main body 1 is provided with a button channel 14 connected to the wiring cavity. The button 7 can be inserted into the button channel 14 so as to slide back and forth. The upper end of the button 7 extends out of the main body 1 through the button channel 14. The lower end of the button 7 is set in the button channel 14 and, in the initial state, lightly touches the surface of the swing end 5. When in use, the upper end of the button 7 is pressed to make its lower end tightly contact with the swing end 5. When pressing the button 7, in order to improve the convenience of operation, a slot structure for facilitating the insertion of a tool can be provided at the upper end of the button 7. When the button 7 is pushed into place, the first clip 6 and the second clip 8 engage and make a snapping sound. At this time, the button 7 is stopped from being pressed to prevent the button 7 from crushing the swing end 5. At the same time, when the button 7 is reset, a limit structure is provided on the inner side wall of the button channel 14. The limit structure can limit the button 7 to slide up and down within a certain range to prevent it from falling off.

[0051] In some embodiments, as Figures 1 to 3 As shown, the swing end 5, the first elastic return member 12, the second elastic return member 13, the first clip 6 and the unlocking structure 11 are an integrated structure formed by bending the two ends of a long elastic sheet into an arc shape. One end of the long elastic sheet is bent to form the swing end 5, and the other end of the long elastic sheet is bent in sequence to form a swing arm 601, a connecting arm 112 and a pushing arm 111.

[0052] In this embodiment, the first elastic return member 12 is located between the swing end 5 and the upper arc-shaped bend, the second elastic return member 13 is located between the first clip 6 and the lower arc-shaped bend, and a fixed end is located between the upper and lower arc-shaped bends. A mating portion that abuts the fixed end is provided in the wiring cavity, and the spring 3 is fixedly disposed in the wiring cavity by abutting the fixed end with the mating portion. In other embodiments, the fixed end and the mating portion can be fixed by riveting or other means. The above structure is simple and easy to assemble. After installation, the integrated structure formed by the unlocking structure 11, the swing end 5, the first clip 6, the first elastic return member 12, and the second elastic return member 13 is positioned and stably in the main body 1.

[0053] In other embodiments, Figure 4As shown, the spring piece 3 is an integrated structure formed by arc-shaped bending at both ends of a long elastic sheet. One end of the long elastic sheet is a swing end 5. The first elastic reset member 12 is located between the swing end 5 and the upper arc-shaped bend. There is also a fixed end between the upper arc-shaped bend and the lower arc-shaped bend. A mating portion that abuts the fixed end is provided in the wiring cavity. After the other end of the long elastic sheet completes the arc-shaped bend at the lower end, it extends horizontally to the travel channel of the wire 10 and is constructed as a pushing arm 111. A swing arm 601 is constructed between the pushing arm 111 and the lower arc-shaped bend. Two hooks 602 are arranged on both sides of the swing arm 601. The second elastic reset member 13 is located between the swing arm 601 and the lower arc-shaped bend. The wire 10 applies thrust to the pushing arm 111, and the pushing arm 111 can rotate and drive the swing arm 601 to rotate. The rotation of the swing arm 601 causes the two hooks 602 to disengage from the second buckle 8.

[0054] In the connector disclosed in this embodiment, the wire 10 extends from the wiring hole 4 into the wiring cavity until it abuts against the pushing arm 111. The pushing arm 111 is pushed by the wire 10, which will drive the connecting arm 112 to move. When the connecting arm 112 moves, it will drive the swing arm 601 to move, and the hook 602 will move with the swing arm 601. The hook 602 will deviate from the second buckle 8 until it is out of the fastening state. At this time, the swing end 5 releases the elastic force and pushes the button 7 to reset. At the same time, the swing end 5 and the conductive contact surface cooperate to clamp the wire 10 inserted into the wiring cavity and complete the wiring action; when it is necessary to take out the wire, press the button 7, and the button 7 pushes the swing end 5 until the second buckle 8 on the button 7 is fastened with the hook 602, thereby fixing the swing end 5 in the avoidance position 9, and then the wire clamping structure is opened and is in the normally open state. At this time, the wire 10 can be taken out to complete the wire taking action.

[0055] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
