Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a wiring terminal mechanism for a switch panel. Background Technology

[0002] Switch panels are very common electrical devices used to control lighting equipment.

[0003] Existing switch panels typically use snap-fit ​​terminals to connect wires. This involves rotating a screw to move it, causing the screw head to press the wire into the terminal for secure connection. However, snap-fit ​​terminals are prone to problems such as wire slippage, damage to wire connections, and unstable wire clamping. Therefore, snap-fit ​​terminals are gradually being phased out.

[0004] Furthermore, the existing switch panel back boxes are all relatively large and thick, but the junction boxes on the wall for installing switch panels are all of uniform standard size. The wires inside the junction box are connected to the switch panel, which means that when the switch panel is installed on the junction box, the wires inside the junction box must be pressed tightly in before the back box can be inserted into the junction box, which is very laborious. Moreover, excessive compression of the wires can easily cause safety hazards.

[0005] Therefore, a terminal block mechanism is needed that can stably connect wires while reducing the size of the junction box. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wiring terminal mechanism for a switch panel to solve the above problems.

[0007] The technical solution of this utility model is implemented as follows: a terminal block mechanism for a switch panel, comprising,

[0008] The base box contains multiple wiring terminals, each terminal including a screw, a terminal frame, and a stationary contact piece. A threaded hole is provided on one side of the terminal frame for threaded connection with the screw. The screw is rotatably connected to the base box and does not move relative to the base box. The terminal frame is slidably connected to the base box and does not rotate relative to the base box. The stationary contact piece extends into the terminal frame and is provided with a stationary contact tip.

[0009] A conductive arm, which is rotatably connected inside the base box and cooperates with a stationary contact;

[0010] The bottom box is equipped with a trigger rocker for rotating the conductive arm. The contact point between the trigger rocker and the conductive arm is closer to the back of the bottom box than the stationary contact.

[0011] By adopting the above technical solution, the terminal block adopts a pull-tab form. When the screw is rotated, the screw does not move and drives the terminal frame to move, thereby clamping the wire between the stationary contact piece and one side of the terminal frame, which effectively improves the connection stability of the wire. Moreover, the depth of the concave conductive arm is increased, so that the height of the conductive arm overlaps with that of the trigger rocker. Therefore, when using the pull-tab form of the terminal block, the thickness of the bottom box can also be effectively reduced.

[0012] The present invention is further configured such that: the conductive arm is U-shaped, the conductive arm includes a base plate, connecting arms located at both ends of the base plate and extending upward, and a contact arm located at the top of the connecting arm and extending outward; the contact arm is provided with a moving contact that cooperates with the stationary contact; and the trigger rocker extends between the two connecting arms and contacts the base plate.

[0013] By adopting the above technical solution, the depth of the concave conductive arm can be increased, making it more suitable for pull-tab type terminals and making higher use of the space inside the box.

[0014] The present invention is further configured such that the included angle between the connecting arm and the base plate is set to 90°-110°.

[0015] By adopting the above technical solution, the conductive arm can make full use of the space inside the base box, and effectively break when the conductive arm swings.

[0016] The present invention is further configured such that: limiting ears protrude from both sides of the base plate, and limiting grooves are provided on the base box for moving with the limiting ears.

[0017] By adopting the above technical solution, the displacement of the conductive arm can be effectively limited through the cooperation of the limiting ear and the limiting groove, so that the conductive arm can rotate stably.

[0018] The present invention is further configured such that: the bottom box is provided with three terminals, namely terminal one, terminal two and terminal three, terminal one and terminal two are arranged side by side, a conductive arm is provided between terminal one and terminal three, the conductive arm is connected to the stationary contact of terminal one or to the stationary contact of terminal three, the stationary contact piece of terminal two is connected to a conductive bar, and the conductive bar extends to the bottom of the bottom plate and maintains constant contact with the bottom plate.

[0019] By adopting the above technical solution, the conductive arm can be effectively broken when it swings.

[0020] The present invention is further configured such that: the back of the bottom box is provided with a wiring opening for wires to be inserted and to cooperate with the terminal frame; the stationary contact piece is arranged in an "L" shape; one side of the stationary contact piece extends into the terminal frame and is close to the threaded hole; and the other side is located on the side of the terminal frame away from the wiring opening.

[0021] By adopting the above technical solution, the wire extends from the wiring opening into the terminal frame and is blocked by the stationary contact piece, thus limiting the distance the wire extends.

[0022] The present invention is further configured such that: a protrusion is provided on the inner wall of the terminal frame on the side away from the threaded hole.

[0023] By adopting the above technical solution, the clamping stability of the wire can be effectively improved, resulting in a better connection effect. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-5 As shown, this utility model discloses a wiring terminal mechanism for a switch panel, comprising,

[0032] The base box 1 is provided with multiple wiring terminals, each including a screw 20, a terminal frame 21, and a stationary contact piece 22. A threaded hole 210 for threaded connection with the screw 20 is provided on one side of the terminal frame 21. The screw 20 is rotatably connected to the base box 1 and does not move relative to the base box 1. The terminal frame 21 is slidably connected to the base box 1 and does not rotate relative to the base box 1. The stationary contact piece 22 extends into the terminal frame 21 and is provided with a stationary contact 220.

[0033] Conductive arm 3, which is rotatably connected inside the base box 1 and cooperates with the stationary contact 220;

[0034] The bottom box 1 is provided with a trigger rocker plate 4 for driving the conductive arm 3 to rotate. The contact point between the trigger rocker plate 4 and the conductive arm 3 is closer to the back of the bottom box 1 than the stationary contact 220.

[0035] By adopting the above technical solution, the wiring terminal adopts a pull-tab form. When the screw 20 is rotated, the screw 20 remains stationary and drives the terminal frame 21 to move, thereby clamping the wire between the stationary contact piece 22 and one side of the terminal frame 21, which effectively improves the connection stability of the wire. Moreover, the depth of the concave conductive arm 3 is increased, so that the height of the conductive arm 3 overlaps with that of the trigger rocker 4. Therefore, when using the pull-tab form of the wiring terminal, the thickness of the bottom box 1 can also be effectively reduced.

[0036] In this embodiment of the utility model, the conductive arm 3 is arranged in a "U" shape. The conductive arm 3 includes a base plate 30, connecting arms 31 located at both ends of the base plate 30 and extending upward, and a contact arm 32 located at the top of the connecting arm 31 and extending outward. The contact arm 32 is provided with a moving contact 33 that cooperates with the stationary contact 220. The trigger rocker plate 4 extends between the two connecting arms 31 and contacts the base plate 30.

[0037] By adopting the above technical solution, the depth of the concave conductive arm 3 can be increased, making it more compatible with pull-tab type wiring terminals and making higher use of the space inside the bottom box 1.

[0038] In this embodiment of the utility model, the angle between the connecting arm 31 and the base plate 30 is set to 90°-110°.

[0039] By adopting the above technical solution, the conductive arm 3 can make full use of the space inside the base box 1, and the conductive arm 3 can effectively break when it swings.

[0040] In this embodiment of the utility model, the bottom plate 30 has protruding limiting ears 34 on both sides, and the bottom box 1 has a limiting groove 10 for moving with the limiting ears 34.

[0041] By adopting the above technical solution, the cooperation between the limiting ear 34 and the limiting groove 10 can effectively limit the displacement of the conductive arm 3, so that the conductive arm 3 can rotate stably.

[0042] In this embodiment of the utility model, the bottom box 1 is provided with three terminals, namely terminal 1 7, terminal 2 5 and terminal 3 6. Terminal 1 7 and terminal 2 5 are arranged side by side. The conductive arm 3 is located between terminal 1 7 and terminal 3 6. The conductive arm 3 is connected to the stationary contact 220 of terminal 1 7 or to the stationary contact 220 of terminal 3 6. The stationary contact piece 22 of terminal 2 5 is connected to a conductive busbar 50. The conductive busbar 50 extends to the bottom of the bottom plate 30 and maintains constant contact with the bottom plate 30.

[0043] By adopting the above technical solution, the conductive arm 3 can be effectively broken when it swings.

[0044] In this embodiment of the utility model, the back of the bottom box 1 is provided with a wiring opening 11 for wires to be inserted and to cooperate with the terminal frame 21. The stationary contact piece 22 is arranged in an "L" shape. One side of the stationary contact piece 22 extends into the terminal frame 21 and is close to the threaded hole 210, while the other side is located on the side of the terminal frame 21 away from the wiring opening 11.

[0045] By adopting the above technical solution, the wire extends from the wiring opening 11 into the terminal frame 21 and is blocked by the stationary contact piece 22, thus limiting the distance the wire extends.

[0046] In this embodiment of the present invention, a protrusion is provided on the inner wall of the terminal frame 21 on the side away from the threaded hole 210.

[0047] By adopting the above technical solution, the clamping stability of the wire can be effectively improved, resulting in a better connection effect.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
