[0004] The utility model solves the technical problems of:

[0005] The existing wireless lamp wiring switch has no protection device, and is easy to cause high temperature and fire due to excessive current.

[0006] To solve the above technical problems, the utility model provides a technical scheme of a new type side by side wiring terminal. The wiring terminal comprises a wiring seat and an upper cover. The wiring seat is detachably clamped on the upper cover. A bimetallic sheet static contact piece assembly and a moving contact piece assembly are clamped between the wiring seat and the upper cover. The moving contact piece assembly is arranged in a J shape. The bimetallic sheet static contact piece assembly is arranged in a shape of a spring piece with the middle part raised and the two ends collapsed. The moving contact piece assembly is partially arranged on the upper side of the bimetallic sheet static contact piece assembly. A manual reset button is slidably arranged on one side of the wiring seat. The manual reset button is arranged on one end of the bimetallic sheet static contact piece assembly. The bimetallic sheet static contact piece assembly is welded and connected with the L pole output end of the conductive spring piece and the pull buckle terminal assembly.

[0007] Further, riveting contact points are arranged on the moving contact piece assembly and the bimetallic sheet static contact piece assembly respectively. The two groups of contact points are tightly attached together.

[0008] Further, a large gear wheel is movably arranged on the wiring seat. The large gear wheel is arranged outside a small gear wheel. The small gear wheel is connected with a key spring and the moving contact piece assembly. The key spring abuts against the moving contact piece assembly. A lamp plate is arranged on the upper side of the large gear wheel. A lamp plate fixing plate is arranged outside the lamp plate. A switch cap is arranged outside the lamp plate fixing plate.

[0009] Further, an N pole conductive spring is arranged in the wiring seat. One end of the N pole conductive spring is connected with the pull buckle terminal assembly. The other end of the N pole conductive spring is connected with a conductive piece. The conductive piece is boltedly connected and arranged on the wiring seat. A spring cover plate is arranged between the N pole conductive spring and the conductive piece.

[0011] Furthermore, a switch reset spring is provided between the lamp board fixing plate and the moving contact assembly.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] Protective current control is achieved by connecting a bimetallic strip in series with the L (live) wire of the switch. If the current is too high, the temperature rises to the maximum limit of the bimetallic strip. As the temperature rises, the bimetallic strip will deform, and the manual reset button will automatically pop up, the contacts will open, and the power indicator light will turn off, cutting off the power supply and preventing fires caused by excessive current and overheating. When the temperature drops, pressing the manual reset button will close the contacts and resume operation. This cycle repeats, thus protecting the safety of electrical appliances and preventing loss of life and property. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figs. 1-3 As shown, this utility model proposes a novel parallel terminal block, including a terminal block 17 and a top cover 18. The terminal block 17 is detachably snapped onto the top cover 18. A bimetallic stationary contact assembly 16 and a moving contact assembly 15 are snapped between the terminal block 17 and the top cover 18. The moving contact assembly 15 is J-shaped, and the bimetallic stationary contact assembly 16 is a spring-shaped assembly with a raised middle and lower ends. The moving contact assembly 15 is partially disposed on the upper side of the bimetallic stationary contact assembly 16. A manual reset button 10 is slidably provided on one side of the terminal block 17. The manual reset button 10 is mounted on one end of the bimetallic stationary contact assembly 16. The bimetallic stationary contact assembly 16 is welded to the L-terminal output terminal of the pull-tab terminal assembly 9 through a conductive spring 6. The moving contact assembly 15 and the bimetallic stationary contact assembly 16 are electrically connected, forming a circuit. The system begins operation by using the bimetallic strip as a support for contact 19. The bimetallic strip stationary contact assembly 16 and the conductive spring 6 are spot-welded together. Utilizing the rocker principle, when the power of the electrical appliance exceeds its rated current, the temperature rises due to the excessive current. The bimetallic strip stationary contact assembly 16 deforms due to the heat, causing contact 19 to dip downwards and contact 19 on the moving contact assembly 15 to spring open, thereby cutting off the external power input. At the same time, the manual reset button is automatically popped up by the edge of the bimetallic strip stationary contact assembly 16. Pressing the manual reset button connects the two contacts, restarting the operation. A lamp board conductive spring 12 is provided between the lamp board fixing plate 2 and the conductive sheet 7, and a switch reset spring 14 is provided between the lamp board fixing plate 2 and the moving contact assembly 15.

[0021] like Figs. 1-3 As shown, contact points 19 are riveted on the moving contact assembly 15 and the bimetallic stationary contact assembly 16 respectively. In use, the two sets of contacts 19 are tightly pressed together. If there is no protection device, under overheating conditions, if the usage time is too long, a fire will occur when the temperature reaches the ignition temperature of the appliance's casing. Now, with this overload protection device, when the temperature reaches the maximum temperature limit of the protection device, the power supply will be automatically cut off.

[0022] like Figs. 1-3As shown, in order to achieve normal switch operation, a large gear 4 is movably mounted on the terminal block 17. The large gear 4 is sleeved on the outside of the small gear 5. The small gear 5 is connected to the moving contact assembly 15 through the button spring 13. The button spring 13 abuts against the moving contact assembly 15. A lamp plate 3 is provided on the upper side of the large gear 4. A lamp plate fixing plate 2 is sleeved on the outside of the lamp plate 3. A switch cap 1 is provided on the outside of the lamp plate fixing plate 2. When the switch cap 1 is pressed, the large gear 4 is under pressure, and the button spring 13 is pressed down to push the moving contact assembly 15. The moving contact assembly 15 and the bimetallic stationary contact assembly 16 form a conductive connection.

[0023] like Figs. 1-3 As shown, in order to maintain the normal use of the lamp board 3, the terminal block 17 is provided with an N-pole conductive spring 11. One end of the N-pole conductive spring 11 is connected to the pull-button terminal assembly 9, and the other end is connected to the conductive sheet 7. The conductive sheet 7 is bolted and installed on the terminal block 17. A spring cover plate 8 is provided between the N-pole conductive spring 11 and the conductive sheet 7.
