Description

Technical Field

[0001] This application relates to the field of terminal blocks, and more particularly to a terminal block and its connector. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections, and are classified as connectors in industry. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually rising.

[0003] In some small electrical appliances, due to the limited internal installation space, smaller-sized terminals are usually required. In order to hold the thin wires, these terminals usually need to have clamping slots. However, in the actual processing, because the size of these terminals is too small, if a punch press is used to directly stamp the clamping slots, the small size of the clamping slots places very demanding requirements on the processing accuracy of the punch press. The punch press may even be unable to successfully stamp the clamping slots. Summary of the Invention

[0004] To reduce the processing difficulty of the aforementioned wiring terminals, this application provides a wire terminal and its connector.

[0005] This application provides a wire terminal and its connector, which adopts the following technical solution: A terminal block includes a main body, on which a clamping part is provided, the clamping parts being arranged opposite each other and located at the same end of the main body; a clamping opening for inserting a power supply line is formed between the oppositely arranged clamping parts, and a clearance hole is formed around the oppositely arranged clamping parts and the main body together, the clearance hole communicating with the clamping opening.

[0006] By adopting the above technical solution, there is no need to use a punch press to press the clamping opening during processing. When processing the raw material, it is only necessary to press the two clamping parts on both sides towards each other and control the distance between the two clamping parts on both sides to a specified width. At this time, the forming work of the clamping opening is completed. The setting of the clearance hole can provide clearance space for the pressing work of the clamping parts, so that the two clamping parts on both sides can bend more smoothly towards each other. This application reduces the processing difficulty of the clamping opening and improves the pass rate of product processing.

[0007] Optionally, the clamping part is provided with reinforcing ribs, which are located on the inner wall of the relief hole; the reinforcing ribs located in the relief hole are arranged opposite to each other; and the main body part has a through-hole for fixing wires.

[0008] By adopting the above technical solution, when the two clamping parts are pressed towards each other, the reinforcing ribs formed on the inner wall of the relief hole can enhance the structural strength of the clamping part, so that the clamping part is not easy to break when it is pressed, thus ensuring the smooth progress of the pressing work; while the wire fixing hole is used for the power supply wire to pass through and realize the connection and fixation of the wire to the main body.

[0009] This application also provides a connector for connecting the aforementioned terminals, including a main body, on which a plurality of mounting members are provided, the mounting members being arranged circumferentially around the outer circumferential surface of the main body; the mounting members are provided with slots for placing the main body, and the mounting members are also provided with wire fixing components for fixing wires to the main body.

[0010] By adopting the above technical solution, some electrical components may require the simultaneous use of multiple of the above-mentioned terminals. The connector disclosed in this application can meet the installation needs of a large number of terminals by installing multiple mounting parts on the outer circumferential surface of the main body. When installing the main body, simply insert the main body into the corresponding slot, and the main body will be initially positioned on the mounting part. When wiring is required, the wire is further connected and fixed to the main body by the wire fixing assembly, which ensures the reliability of the connection between the wire and the main body.

[0011] Optionally, a wire-passing hole is provided on the central axis of the main body, and a wire-fixing seat coaxial with the wire-passing hole is also provided on the main body, and a plurality of wire-fixing grooves are provided on the wire-fixing seat.

[0012] By adopting the above technical solution, the main cable with an outer insulating layer can be passed through the wire hole onto the main body. Then, each main cable is respectively clamped into the corresponding wire fixing groove. At this time, under the joint action of the wire fixing seat and the wire fixing groove, the position of each main cable can be limited and fixed, realizing the connection and fixation between the main cable and the main body. This facilitates the subsequent connection of the wires inside the main cable to the main body, ensuring the reliability of the connection between the wires and the main body.

[0013] Optionally, the wire fixing assembly includes a limiting rod slidably disposed on the mounting component, the limiting rod being directly opposite the wire fixing hole, the wire fixing hole being located on the sliding path of the limiting rod, and the wire fixing hole being able to allow the limiting rod to be inserted; a wire retaining groove is provided on the outer wall of the limiting rod.

[0014] By adopting the above technical solution, when connecting the wire to the main body, the limiting rod is first pushed to insert the end of the limiting rod into the wire fixing hole. Then, the wire is wound around the wire clamping groove. After the wire is wound, the limiting rod is pulled away from the main body. Finally, the wire wound in the wire clamping groove can smoothly pass through the wire fixing hole with the limiting rod, which greatly facilitates the subsequent wire fixing work.

[0015] Optionally, a spring is sleeved on the outside of the limiting rod, and the spring extends and retracts along the sliding direction of the limiting rod; one end of the spring is connected to the limiting rod, and the other end of the spring is connected to the mounting component; the spring is used to push the limiting rod away from the main body.

[0016] By adopting the above technical solution, under normal conditions, the spring will push the limiting rod to remain separated from the wire fixing hole, thus ensuring that the main body can be smoothly inserted into the slot of the mounting part. When it is necessary to connect the wire to the main body, the limiting rod is pressed to overcome the spring force, and the limiting rod can then pass smoothly through the wire fixing hole. After the wire is smoothly wound around the wire-holding groove extending from the wire fixing hole, the user only needs to remove the external force applied to the limiting rod, and the limiting rod will then move away from the main body under the action of the spring force. This ensures that the wire passes smoothly through the wire fixing hole, and the limiting rod can also be locked under the action of the spring.

[0017] Optionally, a first through hole is provided on the outer wall of the limiting rod, and a first limiting member is provided in the first through hole. The first limiting member is slidably disposed in the first through hole along a sliding direction perpendicular to the limiting rod. A screw is threadedly connected to the inside of the limiting rod. The screw is coaxial with the limiting rod, and the first limiting member is located on the moving path of the screw. The screw is used to push the first limiting member out of the opening on the side of the first through hole away from the screw.

[0018] By adopting the above technical solution, after the wire wound in the wire slot passes smoothly through the wire fixing hole along with the limiting rod, the screw is rotated to move it closer to the first through hole. When the screw moves to contact the first limiting member, as the screw rotates further, it can push the first limiting member to extend out from the outer wall of the limiting rod along the first through hole. By pressing the first limiting member against the wire on the main body, the wire can be fixed and the fixing effect can be further improved. When the screw is rotated to move it away from the first limiting member, the screw will finally release the locking of the first limiting member, and the limiting rod can then be smoothly removed from the wire fixing hole.

[0019] Optionally, a second through hole is provided on the outer wall of the limiting rod, and a second limiting member is provided in the second through hole. The second limiting member is also slidably disposed in the second through hole along the sliding direction perpendicular to the limiting rod; and the second limiting member is located on the moving path of the screw; a limiting groove for the insertion of the second limiting member is provided on the inner wall of the mounting component, and the limiting groove is located on the sliding path of the second limiting member.

[0020] By adopting the above technical solution, when the screw moves to contact the second limiting member, one side of the second limiting member will extend out from the outer wall of the limiting rod along the second through hole under the push of the screw. By inserting the extended part of the second limiting member into the limiting groove, the limiting member and the mounting part can be fixed in a limiting manner. The screw will push both the first and second limiting members out from the outer wall of the limiting rod. At this time, under the combined action of the first and second limiting members, the main body and the limiting rod can be stably and reliably limited on the mounting part.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. During processing, there is no need to use a punch press to press the clamping opening. When processing the raw material, you only need to press the two clamping parts on both sides towards each other and control the distance between the two clamping parts on both sides to a specified width. At this time, the forming of the clamping opening is completed. 2. It reduces the processing difficulty of the clamping opening and improves the product qualification rate during processing; 3. Capable of handling the installation of large quantities of terminal blocks. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a wiring terminal block. (Refer to...) Figure 1 The terminal block includes a main body 1 made of conductive copper. One end of the main body 1 is bent to form two clamping parts 2 that are close to each other. The clamping parts 2 are arranged opposite each other and are symmetrical. A clamping opening 20 for inserting the power supply line is formed between the clamping parts 2. The width of the clamping opening 20 gradually increases from the end closer to the main body 1 to the end farther away from the main body 1.

[0030] like Figure 1 As shown, the inner walls of the two clamping parts 2 and the main body 1 together form a clearance hole 21. The clearance hole 21 is located on the side of the clamping opening 20 closer to the main body 1, and the clearance hole 21 is interconnected with the clamping opening 20. A reinforcing rib 211 is integrally formed on the inner wall of the clearance hole 21 on the clamping part 2. The reinforcing ribs 211 in the clearance hole 21 are arranged opposite each other and are located on the side wall of the clamping part 2 that is subjected to external pressure during processing. When the two clamping parts 2 are pressed towards each other, the reinforcing ribs 211 formed on the inner wall of the clearance hole 21 enhance the structural strength of the clamping part 2, making it less prone to breakage under external pressure and ensuring smooth pressing operations. A wire-fixing hole 10 is provided at the end of the main body 1 away from the clamping part 2. The wire-fixing hole 10 is used for external wires to pass through for wiring.

[0031] The implementation principle of a terminal block according to this application embodiment is as follows: During processing, there is no need to use a punch press to press the clamping opening 20. When processing the raw material, it is only necessary to press the two clamping parts 2 towards each other, and control the distance between the two clamping parts 2 at a specified width. At this time, the forming work of the clamping opening 20 is completed. The setting of the clearance hole 21 provides clearance space for the pressing work of the clamping parts 2, allowing the two clamping parts 2 to bend more smoothly towards each other. This application reduces the processing difficulty of the clamping opening 20 and improves the product qualification rate during processing.

[0032] This application embodiment also provides a connector for connecting the aforementioned wiring terminals, such as... Figure 2 , Figure 3 As shown, the device includes a frustum-shaped main body 3, which is injection molded from plastic. A collar 30 is rotatably mounted on the outer circumference of the main body 3. The collar 30 is coaxial with the main body 3 and rotates around the central axis of the main body 3. Multiple mounting parts 31 are fixedly mounted on the collar 30, and the mounting parts 31 are arranged at uniform intervals around the outer circumference of the collar 30. The side wall of the mounting parts 31 opposite to the collar 30 has a slot 32 for the main body 1 to be inserted.

[0033] like Figure 2 , Figure 3 As shown, a through-hole 33 for the main cable, which is externally insulated, passes through the central axis of the main body 3. A cable holder 5, coaxial with the through-hole 33, is integrally formed on the main body 3, circumferentially surrounding the through-hole 33. Multiple U-shaped cable grooves 51 are formed along the upper edge of the cable holder 5, arranged at even intervals. The main cable passes through the through-hole 33 onto the main body 3, and then each main cable is secured in its corresponding cable groove 51. The combined action of the cable holder 5 and the cable grooves 51 limits and fixes the position of each main cable, thus achieving a secure connection between the main cable and the main body 3. This facilitates the subsequent connection of the internal wires of the main cable to the main body 1, ensuring the reliability and stability of the connection.

[0034] like Figure 4 , Figure 5 As shown, each mounting component 31 is equipped with a wire-fixing assembly 4 for securing the wire to the main body 1. When wiring is required, the wire-fixing assembly 4 further connects and fixes the wire to the main body 1, ensuring the reliability of the connection. The wire-fixing assembly 4 includes a limiting rod 41 mounted on the mounting component 31. The limiting rod 41 is slidably mounted on the mounting component 31 in a direction perpendicular to the insertion slot 32 of the respective main body 1. When the main body 1 is installed in the designated position of the respective mounting component 31, one end of the limiting rod 41 is directly opposite the corresponding wire-fixing hole 10, and the wire-fixing hole 10 is located on the sliding path of the corresponding limiting rod 41. The end of the limiting rod 41 can pass through the corresponding wire-fixing hole 10.

[0035] like Figure 4 , Figure 5As shown, a wire-holding groove 410 is provided on the outer wall of the limiting rod 41. The wire-holding groove 410 is used for winding the power supply wire and limiting the wire on the limiting rod 41. A spring 411 is sleeved on the outside of the limiting rod 41 and located inside the mounting member 31. The spring 411 extends and retracts along the sliding direction of the limiting rod 41. One end of the spring 411 is connected and fixed to the limiting rod 41, and the other end of the spring 411 is connected and fixed to the inner wall of the mounting member 31. In its natural state, the spring 411 will apply a spring force to the limiting rod 41 in a direction away from the main body 1, causing the end of the limiting rod 41 to retract from the wire-fixing hole 10.

[0036] In its natural state, the spring 411 will push the limiting rod 41 to remain separated from the wire-fixing hole 10, ensuring that the main body 1 can be smoothly inserted into the slot 32 of the mounting part 31. When it is necessary to connect the wire to the main body 1, the limiting rod 41 is pressed to overcome the elastic force of the spring 411, allowing the limiting rod 41 to pass smoothly through the wire-fixing hole 10. After the wire is smoothly wound around the wire-holding groove 410 extending from the wire-fixing hole 10, the user only needs to remove the external force applied to the limiting rod 41. At this time, the limiting rod 41 will move away from the main body 1 under the elastic force of the spring 411. This ensures that the wire passes smoothly through the wire-fixing hole 10, and the limiting rod 41 is also locked under the action of the spring 411.

[0037] like Figure 4 , Figure 5 As shown, a first through hole 42 is provided on the outer wall of the limiting rod 41, and the first through hole 42 is located on the side of the wire-locking groove 410 away from the spring 411. A spherical first limiting member 420 is provided in the first through hole 42, and the first limiting member 420 is slidably disposed in the first through hole 42 along the sliding direction perpendicular to the limiting rod 41. One side opening of the first through hole 42 communicates with the interior of the limiting rod 41, and the other side opening of the first through hole 42 is located on the outer wall of the limiting rod 41. A screw 43 is threadedly connected to the inside of the limiting rod 41, and the screw 43 is coaxial with the limiting rod 41. By rotating the screw 43, the screw 43 will slide within the limiting rod 41 along the length direction of the limiting rod 41. A guide plate 412 located in the mounting member 31 is fixedly installed on the outer wall of the limiting rod 41, and a guide groove 310 for the insertion of the guide plate 412 is provided on the inner wall of the mounting member 31, and the guide groove 310 extends along the sliding direction of the limiting rod 41. The guide plate 412 is inserted into the guide groove 310, and the guide plate 412 slides along the length of the guide groove 310.

[0038] like Figure 4 , Figure 5As shown, the first limiting member 420 is located on the moving path of the screw 43. When the screw 43 moves to contact the first limiting member 420, as the screw 43 moves further, it will push one side of the first limiting member 420 out of the opening of the first through hole 42 on the outer wall of the limiting rod 41. At this time, by pressing the first limiting member 420 against the wire on the main body 1, the wire can be limited and fixed, further improving the fixing effect of the wire. When the screw 43 is rotated to move away from the first limiting member 420, the screw 43 will finally release the lock on the first limiting member 420, and the limiting rod 41 can then be smoothly removed from the wire fixing hole 10.

[0039] like Figure 4 , Figure 5 As shown, a second through hole 44 is also provided on the outer wall of the limiting rod 41. One side opening of the second through hole 44 communicates with the interior of the limiting rod 41, and the other side opening of the second through hole 44 is located on the outer wall of the limiting rod 41. The second through hole 44 is located on the side of the wire clamping groove 410 near the spring 411. A spherical second limiting member 45 is also provided in the second through hole 44. The second limiting member 45 is also slidably disposed in the second through hole 44 along the sliding direction perpendicular to the limiting rod 41. The second limiting member 45 is also located on the moving path of the screw 43. A limiting groove 34 for the insertion of the second limiting member 45 is provided on the inner wall of the mounting part 31. The limiting groove 34 is arc-shaped and located on the sliding path of the second limiting member 45.

[0040] The implementation principle of a connector in this application embodiment is as follows: by installing multiple mounting parts 31 on the outer circumferential surface of the main body 3, the installation of a large number of terminals can be achieved. When installing the main body 1, simply insert the main body 1 into the corresponding slot 32, at which point the main body 1 is initially positioned on the mounting part 31. When wiring is required, the wire is further connected and fixed to the main body 1 by the wire fixing assembly 4, thus ensuring the reliability of the connection between the wire and the main body 1. After the wire wound in the wire clamping groove 410 passes smoothly through the wire fixing hole 10 with the limiting rod 41, the screw 43 is rotated to move towards the first through hole 42. When the screw 43 moves to contact the first limiting part 420, with the further rotation of the screw 43, the screw 43 can push the first limiting part 420 to extend out from the outer wall of the limiting rod 41 along the first through hole 42. At this time, the wire can be pressed tightly onto the main body 1 by the first limiting part 420.

[0041] 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.
