Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment technology, specifically to a non-standard terminal block for preventing mis-insertion. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They are widely used in power electronic equipment, control systems and other fields. They can connect different wires together in a standardized manner, which facilitates the installation, maintenance and repair of the lines. Irregular terminal blocks are non-standard terminal blocks that break through the regular shape of traditional terminal blocks to adapt to different installation spaces and connection methods. They are usually used to meet special electrical connection requirements.

[0003] The existing technology has the following problems:

[0004] Existing terminals can be quickly connected or disconnected via plugs and sockets, facilitating equipment maintenance and replacement, and offering high connection efficiency. However, they pose a risk of mis-insertion in complex systems, especially in scenarios involving mixed connections of multiple circuits and various wire specifications. Traditional anti-mis-insertion structures are mostly single-slot or coded designs, which are insufficient in terms of reliability and ease of operation when facing high-density wiring and the need for rapid plugging and unplugging. Furthermore, they are assumed to be powered on after wiring, resulting in lower safety. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a non-misconnection shaped terminal block, which solves the problems of error and instantaneous power supply.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: the irregularly shaped terminal block for preventing mis-insertion includes a mounting base, a terminal post is provided at the top of the mounting base, a plurality of wiring interfaces are provided at the rear end of the terminal post, a power-conducting post is provided in front of the wiring interface, and a wiring connector is provided inside the wiring interface.

[0007] Preferably, the terminal block includes a terminal block body fixedly connected to the top of the mounting base, and a U-shaped conductive bar is fixedly connected inside the terminal block body.

[0008] Preferably, the wiring interface includes an insertion port located at the rear end of the connector body. The left and right ends of the inner side of the insertion port are provided with trapezoidal slots, and the upper and lower ends of the inner side of the insertion port are provided with arc-shaped grooves. A contact component is fixedly connected to the front end of the inner side of the insertion port, and a cross-shaped positioning rib is fixedly connected to the inner side of the insertion port. The cross-shaped positioning rib is located in front of the insertion port.

[0009] Preferably, the contact assembly includes a contact block slidably connected to the inside of the insertion port, a return spring fixedly connected to the middle of the front end of the contact block and the inside of the conductive bar, contact arc grooves being provided on the upper and lower sides of the front end of the contact block, and fixing springs fixedly connected to the inner wall of the insertion port being provided on the left and right sides of the contact block.

[0010] Preferably, the energized post includes two contact posts rotatably connected inside the post body. The two contact posts are located on the upper and lower sides of the reset spring, respectively. An insulating layer is fixedly connected to three-quarters of the outer surface of the contact post. The end of the contact post away from the post body extends to the outside of the post body and is fixedly connected to an unlocking knob.

[0011] Preferably, the front side of the contact post is in close contact with the rear end of the conductive busbar, and a quarter of the outer surface of the contact post can enter the contact arc groove and be in close contact with the inner side.

[0012] This utility model provides a wiring interface and a power supply post. Compared with the prior art, it has the following advantages:

[0013] 1. This anti-misplugging irregular-shaped terminal block, through the setting of trapezoidal slots, arc grooves, cross positioning ribs and other structures, can better cope with the needs of high-density wiring and rapid plugging and unplugging compared with the traditional single slot or coding design. In the scenario of mixed connection of multiple circuits and multiple specifications of wires, these special structures work together to position and restrict the plug from multiple dimensions, greatly reducing the risk of misplugging and improving the reliability of anti-misplugging.

[0014] 2. This anti-misconnection irregular-shaped terminal block, through its insulating energized posts and contact components, does not automatically energize during wiring. It only energizes after the contact post contacts the contact block by rotating the unlocking knob, thus avoiding safety accidents caused by misconnection and significantly enhancing the safety of operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1-5 This utility model provides a technical solution: an irregularly shaped terminal block for preventing mis-insertion, including a mounting base 4, a terminal post 1 at the top of the mounting base 4, a plurality of wiring interfaces 2 at the rear end of the terminal post 1, a power-conducting post 3 at the front of the wiring interface 2, and a wiring connector 5 inside the wiring interface 2.

[0023] First, connect the connector 5 to the wire and then insert it into the interface 2. Because the interface 2 has a special structure, it can prevent misinsertion. After insertion, the connector 5 connects to the corresponding internal components of the interface 2. At this time, the line is not energized. You need to rotate the energizing post 3 to energize the line and complete the overall process of wiring and energizing.

[0024] Please see Figure 2 The terminal block 1 includes a terminal block body 12 fixedly connected to the top of the mounting base 4. A U-shaped conductive busbar 11 is fixedly connected inside the terminal block body 12. The terminal block body 12 provides a stable mounting base. The U-shaped conductive busbar 11 is responsible for distributing and conducting current. Through cooperation with other components, it realizes electrical connection with other lines.

[0025] Please see Figure 2 The wiring interface 2 includes an insertion port 23 located at the rear end of the connector body 12. Trapezoidal slots 24 are provided on the left and right sides of the inner side of the insertion port 23. Arc grooves 25 are provided on the upper and lower sides of the inner side of the insertion port 23. A contact component 21 is fixedly connected to the front end of the inner side of the insertion port 23. A cross positioning rib 22 is fixedly connected to the inner side of the insertion port 23. The cross positioning rib 22 is located in front of the insertion port 23.

[0026] When the connector 5 is inserted into the insertion port 23, the trapezoidal slot 24 and the arc grooves 25 at the upper and lower ends cooperate with the corresponding parts of the connector 5 to position and guide it from multiple directions, ensuring that the connector 5 can be accurately inserted. The cross positioning rib 22 further assists in positioning and prevents the connector 5 from rotating. During the insertion process, the connector 5 pushes the contact component 21, but the line will not be energized before the insertion is completed and subsequent operations are completed.

[0027] Please see Figure 3 The contact assembly 21 includes a contact block 213 that is slidably connected to the inside of the insertion port 23. A return spring 214 is fixedly connected to the middle of the front end of the contact block 213 and the inside of the conductive busbar 11. Contact arc grooves 212 are provided on the upper and lower sides of the front end of the contact block 213. Fixing springs 215 that are fixedly connected to the inner wall of the insertion port 23 are provided on the left and right sides of the contact block 213.

[0028] Please see Figure 4 The energized post 3 includes two contact posts 32 rotatably connected inside the post body 12. The two contact posts 32 are located on the upper and lower sides of the reset spring 214, respectively. An insulating layer 33 is fixedly connected to three-quarters of the outer surface of the contact post 32. The end of the contact post 32 away from the post body 12 extends to the outside of the post body 12 and is fixedly connected to an unlocking knob 31.

[0029] Please see Figures 4-5 The front side of the contact post 32 is tightly attached to the rear end of the conductive busbar 11. A quarter of the outer surface of the contact post 32 can enter the contact arc groove 212 and be tightly attached to the inner side. The wiring connector 5 is inserted into the inner side of the wiring interface 2.

[0030] When connector 5 is inserted into insertion port 23, connector 5 will push contact block 213 to slide within insertion port 23. At this time, reset spring 214 is compressed, generating elastic force. When connector 5 is not fully inserted or no subsequent power-on operation is performed, the circuit is in a non-powered state.

[0031] When not unlocked, the contact block 213 can only contact the insulating layer 33, preventing the two contact posts 32 from connecting the circuit. When the unlocking knob 31 is turned to rotate the contact posts 32, the contact block 213 can continue to move forward and the fixing spring 215 fixes the wiring connector 5. When the outer surfaces of the two contact posts 32 simultaneously enter the contact arc groove 212 and are tightly against the inner side, the contact block 213 connects with the contact posts 32, and the current can pass through the conductive busbar 11, the contact block 213 and other components to form a path and realize power supply.

[0032] If connector 5 is pulled out, the reset spring 214 will push the contact block 213 to reset, the contact block 213 will disengage from the contact post 32, and the circuit will be disconnected.

[0033] Please see Figures 1-5 At work,

[0034] Connect the wire to the connector 5, align it with the insertion port 23 and insert it. The trapezoidal slot 24, arc groove 25 and cross positioning rib 22 of the insertion port 23 work together to ensure that the connector 5 is accurately inserted and does not rotate. During the insertion process, the connector 5 pushes the contact block 213 to slide, and the return spring 214 is compressed. However, the circuit is not energized at this time because the contact block 213 is in contact with the insulation layer 33 of the contact post 32. Turn the unlocking knob 31 to drive the contact post 32 to rotate. When the outer surface of the contact post 32 enters the contact arc groove 212 and is in close contact with the inner side, the current forms a path through the conductive busbar 11 and the contact block 213, and the power is turned on.

[0035] To disconnect the power, unplug the connector 5. The reset spring 214 will push the contact block 213 to reset, and the contact block 213 will disengage from the contact post 32, thus breaking the circuit.
