Description

Technical Field

[0001] This application relates to the field of terminal blocks, and more particularly to a terminal block with an integrated double-clamp automatic wiring mechanism. Background Technology

[0002] In the field of electrical connections, terminal blocks, as key components for realizing electrical connections between wires and electrical equipment and lines, are widely used in many scenarios such as industrial control, power systems, instrumentation, and smart homes.

[0003] In related technologies, wires are usually fixed to terminals. When a wire is damaged, the original connection structure needs to be destroyed before the wire can be replaced, which is cumbersome and needs improvement. Summary of the Invention

[0004] To address the problem of cumbersome operation requiring the destruction of the original connection structure and replacement of the wire after damage, this application provides an integrated double-clamp automatic wiring terminal.

[0005] The terminal block provided in this application is an integrated double-clamp automatic wiring terminal, which adopts the following technical solution:

[0006] A terminal block for automatic wiring with integrated double-clamping includes a base with an inlet for inserting wires, a spring, and a handle. The spring is located inside the inlet and includes a connecting part, a clamping part, and a triggering part located on both sides of the connecting part. The clamping part is located on the side of the connecting part closer to the inlet. The triggering part has an inner latch and an outer latch. The inner latch is located on the side of the outer latch closer to the connecting part and is used to clamp the clamping part. A limiting block is provided on the base and is located on the side of the clamping part away from the connecting part. The handle extends between the limiting block and the clamping part and abuts against the clamping part and the limiting block. The outer latch is used to clamp the handle. When the outer latch clamps the handle, the inner latch clamps the clamping part, and the clamping part is used to press the wire against the base.

[0007] By adopting the above technical solution, when it is necessary to connect the wire, the handle is lifted, and the handle squeezes the clamping part, causing the clamping part to bend and approach the inner buckle. At this time, the limit block abuts against the handle, keeping the handle in abutting against the clamping part, preventing the handle from disengaging from the clamping part when lifted. The inner buckle then locks the clamping part to limit its position. At this time, the outer buckle locks the handle to limit its position, and the terminal block is in the triggered state. Then, the wire is inserted into the inlet, and the wire passes over the clamping part and abuts against the triggering part, causing the triggering part to move away from the clamping part. When the triggering part disengages from the clamping part, the clamping part resets under the action of elasticity, pressing the wire against the base to achieve clamping, thereby realizing the installation of the wire on the base.

[0008] When the wire is damaged, press the handle. The handle squeezes the clamping part, causing the clamping part to move away from the wire, thus releasing the wire and allowing it to be removed directly. At this time, the triggering part resets under the action of the spring, causing the inner buckle to lock the clamping part. Then, lift the handle, causing the outer buckle to lock the handle, which will put the terminal block back into the triggering state, so as to facilitate subsequent wire installation. Through the cooperation between the handle and the spring, a detachable connection between the wire and the terminal block can be achieved, and the operation is convenient.

[0009] Optionally, the base includes a base body and a conductive sheet disposed on the base body, and the clamping part is used to press the wire against the conductive sheet.

[0010] By adopting the above technical solution, a complete current path is formed, ensuring stable circuit conduction.

[0011] Optionally, the conductive sheet includes a sheet body and a positioning block disposed on the sheet body, and the connecting portion has a positioning hole for the positioning block to be engaged.

[0012] By adopting the above technical solution, positioning blocks and positioning holes are set. The positioning blocks abut against the inner wall of the positioning holes to achieve positioning between the spring sheet and the conductive sheet. This allows the clamping part to apply stable pressure to the wire, reducing the situation where the pressure is too high (which may damage the wire) or too low (which may cause poor contact) due to positional deviation. It can also reduce unnecessary friction, reduce component wear, and extend the service life of the entire terminal block.

[0013] Optionally, the conductive sheet is provided with anti-slip texture, which is located on the side of the conductive sheet near the clamping part.

[0014] By adopting the above technical solution and setting anti-slip texture, the static friction between the conductive sheet and the wire is increased, reducing the possibility of wire slippage.

[0015] Optionally, a power test hole is provided on the base.

[0016] By adopting the above technical solution, it is convenient to insert the test pen into the power test hole for subsequent electrical testing.

[0017] Optionally, the handle is provided with a locking block, the locking block is provided with an inclined surface, the inclined surface is located on the side of the locking block near the clamping part and is inclined towards the clamping part and close to the handle, the base is provided with a mounting groove for the handle to be inserted, the mounting groove is connected to the inlet, when the handle is inserted into the mounting groove, the locking block is used to abut against the inner wall of the inlet.

[0018] By adopting the above technical solution, a locking block and a mounting slot are set. When installing the handle, the handle is inserted into the mounting slot, and the base presses the locking block along the inclined surface, causing the locking block to deform so that it can be inserted into the mounting slot and enter the inlet. Then the locking block returns to its original position and abuts against the inner wall of the inlet, thus achieving the installation and positioning of the handle on the base. No other tools are needed, making the installation of the handle more convenient.

[0019] Optionally, the handle includes a main body and a tail hook disposed on the main body. The outer buckle, inner buckle, and trigger part are spliced ​​together to form a slot, the slot for the tail hook to be inserted into, and the outer buckle for locking the tail hook.

[0020] By adopting the above technical solution and setting a tail hook, a mechanical engagement is formed between the handle and the outer buckle, improving the anti-dislodgement effect of the handle when the terminal is triggered.

[0021] Optionally, the clamping part is provided with a force-receiving protrusion one, and the handle is provided with a force-receiving protrusion two. The handle abuts against the force-receiving protrusion one through the force-receiving protrusion two, thereby abutting against the clamping part.

[0022] By adopting the above technical solution, force-bearing protrusion one and force-bearing protrusion two are set to form a fulcrum, which makes it easy for the clamping part to deform and bend towards the connecting part under the pressure of the handle.

[0023] Optionally, the clamping part and the connecting part are connected by an arc-shaped transition, and the connecting part and the triggering part are connected by an arc-shaped transition.

[0024] By adopting the above technical solution, the stress distribution of the arc transition connection is more uniform, which allows the connection between the clamping part and the connecting part, as well as the connection between the connecting part and the triggering part, to withstand repeated bending at a larger angle. The recovery ability after deformation is stronger, the elastic range is wider, and it is beneficial to extend the service life of the spring.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The detachable connection between the wire and the terminal is achieved through the cooperation between the handle and the spring, and the operation is convenient;

[0027] 2. By setting positioning blocks and positioning holes, the positioning between the spring and the conductive sheet is achieved, so that the clamping part can apply stable pressure to the wire, reducing the situation where the pressure is too high (which may damage the wire) or too low (causing poor contact) due to positional deviation. It can also reduce unnecessary friction, reduce component wear, and extend the service life of the entire terminal block.

[0028] 3. By setting up a locking block and mounting slot, the installation of the handle is made more convenient without the need for other tools. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0039] This application discloses a terminal block for integrated double-clamp automatic wiring. See also... Figures 1-4The terminal block of the integrated double snap-on automatic wiring device includes a base 1, a spring 2 and a handle 3. The base 1 includes a seat body 11 and a conductive sheet 12. Several wire inlets 111 are provided on the outer side wall of the seat body 11. The several wire inlets 111 are located on the same side of the seat body 11 and are evenly spaced along the horizontal direction. The wire inlets 111 are used for wire insertion. In this embodiment, the material of the seat body 11 is nylon (resin), which has a high flame retardant effect.

[0040] See Figures 1-4 The number and position of the conductive plates 12 correspond one-to-one with the number and position of the inlet ports 111. Each conductive plate 12 includes a plate body 121 and a positioning block 122. The plate body 121 is fixed on the base 11 and extends into the corresponding inlet port 111. The positioning block 122 is located in the inlet port 111 and is integrally fixed on the plate body 121. The plate body 121 and the positioning block 122 are both made of copper, which has the function of high-efficiency conductivity.

[0041] See Figures 1-4 The outer wall of the base 11 is also provided with several power test holes 113. The power test holes 113 are located on the side of the base 11 adjacent to the inlet 111, and the number and position of the power test holes 113 correspond one-to-one with the number and position of the inlet 111. The power test holes 113 face the plate 121. In actual use, the power test holes 113 are used for inserting a test pen to perform electrical tests.

[0042] See Figures 1-4 The number and position of the spring pieces 2 correspond one-to-one with the number and position of the wire inlets 111. Each spring piece 2 is located inside the corresponding wire inlet 111 and above the positioning block 122. Each spring piece 2 includes a connecting part 21, a clamping part 22, and a triggering part 23. A positioning hole 211 is provided on the outer wall of the connecting part 21, which vertically penetrates the connecting part 21 and allows the positioning block 122 to be inserted. The clamping part 22 and the triggering part 23 are located on both sides of the connecting part 21, with the clamping part 22 located on the connecting part 21 near the corresponding wire inlet 111. On one side of the inlet 11, the clamping part 22 is inclined away from the inlet 111 and away from the connecting part 21. The connecting part 21, the clamping part 22 and the trigger part 23 are integrally formed. The clamping part 22 and the connecting part 21 are connected by an arc-shaped transition. The connecting part 21 and the trigger part 23 are connected by an arc-shaped transition. The clamping part 22 is used to press the wire against the conductive sheet 12. Each clamping part 22 is bent away from the connecting part 21 to form a force-bearing protrusion 221. In this embodiment, the spring 2 is made of stainless steel and plays a role in repeated rebound.

[0043] See Figures 1-4Anti-slip texture 4 is formed on the outer side wall of the sheet 121. The anti-slip texture 4 is located on the side of the sheet 121 near the clamping part 22 and on the side of the clamping part 22 away from the connecting part 21. The anti-slip texture 4 and the clamping part 22 are arranged opposite to each other.

[0044] See Figures 1-7 The trigger part 23 is bent towards the clamping part 22 at both ends in the horizontal direction. An inner latch 5 and an outer latch 6 are integrally fixed at both ends of the trigger part 23 in the horizontal direction. Both the inner latch 5 and the outer latch 6 are located on the side of the trigger part 23 closest to the clamping part 22, with the inner latch 5 located on the side of the outer latch 6 closest to the connecting part 21. The inner latches 5 at both ends of the trigger part 23 are aligned in the horizontal direction, and the outer latches 6 at both ends of the trigger part 23 are also aligned in the horizontal direction. The inner latch 5 is used to clamp the clamping part 22. The outer wall of the inner buckle 5 of the clamping part 22 is machined with a guide surface. The guide surface is located on the side of the inner buckle 5 away from the connecting part 21, and the guide surface is inclined towards the clamping part 22 in the direction of the connecting part 21. When the clamping part 22 bends close to the inner buckle 5, the clamping part 22 presses against the guide surface, causing the trigger part 23 to bend away from the clamping part 22. This makes it easier for the trigger part 23 to reset after the clamping part 22 passes the inner buckle 5, so that the inner buckle 5 can lock the clamping part 22.

[0045] See Figures 1-7 A limiting block 7 is integrally fixed on the base 11. The number and position of the limiting block 7 correspond one-to-one with the number and position of the inlet 111. Each limiting block 7 is located in the corresponding inlet 111 and is located on the side of the clamping part 22 away from the connecting part 21.

[0046] See Figures 1-7 The number and position of the handles 3 correspond one-to-one with the number and position of the spring pieces 2. The handles 3 are located on the side of the clamping part 22 away from the connecting part 21. The handles 3 include a main body 31 and a tail hook 32. The main body 31 extends between the limiting block 7 and the corresponding clamping part 22 and abuts against the limiting block 7. Each main body 31 has a force-receiving protrusion 211 protruding on its outer side wall in the direction close to the corresponding clamping part 22. The main body 31 abuts against the force-receiving protrusion 1 221 through the force-receiving protrusion 211, thereby abutting against the corresponding clamping part 22.

[0047] See Figures 1-7 The tail hook 32 is located on the side of the main body 31 near the trigger part 23 and is fixed integrally with the main body 31. The outer buckle 6, the inner buckle 5 and the trigger part 23 are spliced ​​to form a groove 8, which is for the tail hook 32 to be inserted into. The outer buckle 6 is used to hold the tail hook 32. When the outer buckle 6 holds the tail hook 32, the inner buckle 5 holds the clamping part 22. In this embodiment, the main body 31 and the tail hook 32 are both made of glass fiber reinforced nylon (resin), which can improve the strength and wear resistance of the handle 3.

[0048] See Figures 1-8A groove 9 is provided on the outer wall of the main body 31 near the clamping part 22. Two locking blocks 10 are integrally fixed on the main body 31. Both locking blocks 10 are located in the groove 9 and are located on both sides of the groove 9 respectively. An inclined surface 13 is formed on the outer wall of each locking block 10. The inclined surface 13 is located on the side of the locking block 10 near the clamping part 22 and is inclined towards the main body 31 in the direction of approaching the clamping part 22. That is, the inclined surfaces 13 on the two locking blocks 10 are far away from each other in the direction of approaching the clamping part 22.

[0049] See Figures 1-8 The outer wall of the base 11 near the power test hole 113 is provided with a mounting groove 112 for the main body 31 and the tail hook 32 to be inserted. The mounting groove 112 is located on the side of the power test hole 113 near the inlet 111, and the mounting groove 112 is connected to the inlet 111. When the main body 31 and the tail hook 32 are inserted into the mounting groove 112, the locking block 10 is used to abut against the inner wall of the inlet 111. In this embodiment, the material of the locking block 10 is glass fiber reinforced nylon (resin), which has a certain elasticity and can meet the need for the locking block 10 to be inserted into the mounting groove 112.

[0050] In actual use, when installing the handle 3, the main body 31 and the tail hook 32 are inserted into the mounting groove 112. The base 11 presses the locking block 10 along the inclined surface 13, causing the locking block 10 to deform so that the locking block 10 can be inserted into the mounting groove 112 and enter the cable inlet 111. Then the locking block 10 returns to its original position. By the locking block 10 abutting against the inner wall of the cable inlet 111, the handle 3 can be installed and positioned on the base 11.

[0051] The implementation principle of the wiring terminal of the integrated double-clamp automatic wiring embodiment of this application is as follows:

[0052] When it is necessary to connect the wire, the main body 31 is lifted. The main body 31 presses the first force protrusion 221 through the second force protrusion 311, which in turn presses the clamping part 22, causing the clamping part 22 to bend and approach the inner buckle 5. At this time, the limit block 7 abuts against the main body 31, so that the second force protrusion 311 on the main body 31 remains in the state of abutting against the first force protrusion 221 on the clamping part 22, so as to prevent the second force protrusion 311 from disengaging from the first force protrusion 221 when the main body 31 is lifted, until the inner buckle 5 locks the clamping part 22 and limits the clamping part 22. At this time, the outer buckle 6 locks the tail hook 32 to limit the tail hook 32, and the terminal is in the triggered state.

[0053] Insert the wire into the inlet 111, pass the clamping part 22 and press against the trigger part 23, so that the trigger part 23 moves away from the clamping part 22. When the trigger part 23 disengages from the clamping part 22, the clamping part 22 resets under the action of elasticity and presses the wire against the conductive plate 12 to achieve clamping, thereby realizing the installation of the wire on the base 11.

[0054] When the wire is damaged, press the main body 31. The main body 31, through the force-bearing protrusion 211, squeezes the force-bearing protrusion 221, which in turn squeezes the clamping part 22, causing the clamping part 22 to move away from the wire, thereby releasing the wire and allowing it to be taken out directly. At this time, the trigger part 23 resets under the action of the elastic force, causing the inner buckle 5 to lock the clamping part 22. Then, lift the main body 31, causing the outer buckle 6 to lock the tail hook 32, so that the terminal block is in the trigger state again, which is convenient for subsequent wire installation. Through the cooperation between the handle 3 and the spring piece 2, the detachable connection between the wire and the terminal block is realized, and the operation is convenient.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
