Description

Technical Field

[0001] This application relates to the technical field of terminal blocks, and in particular to a terminal block and its crimping device. Background Technology

[0002] Terminal blocks, as fundamental components for electrical connections in electronic and electrical equipment and circuits, play a crucial role in modern electrical systems. With the continuous development of electronic and electrical technologies, the application range of various electronic devices and electrical systems is becoming increasingly widespread. From household appliances in daily life to control cabinets in industrial production, and even high-end electronic equipment in aerospace and other fields, all rely on terminal blocks to realize the transmission of electrical energy and signals. The reliability, stability, and convenience of terminal block connections directly affect the safety and performance of the entire circuit system. Their performance is of great significance for ensuring the normal operation of electrical equipment, improving production efficiency, and reducing maintenance costs.

[0003] In traditional wiring processes, the mainstream method for connecting wires to terminals is soldering. In practice, the conductor of the wire is first stripped and tinned. Then, the exposed conductor is inserted into or overlapped onto the pad or pin of the terminal. A soldering iron or similar tool is then used to heat the solder, melting it and filling the gap between the conductor and the terminal. After cooling and solidification, a mechanical and electrical connection is formed. This traditional soldering method has long been widely used in the electronics and electrical fields and is a relatively mature wiring method applied in many areas, including printed circuit boards, distribution boxes, household appliances, and industrial control cabinets.

[0004] However, traditional soldering methods have significant limitations. The amount of solder is difficult to control precisely; too much solder leads to oversized solder joints and irregular protrusions, while too little solder results in poor connection strength and conductivity, making it difficult to guarantee consistency in mass production. Irregular, oversized solder joints can affect subsequent processes. For example, when inserting terminals into plastic housings, they can easily interfere with the housing's slots or latches, causing assembly difficulties or even damage to the housing. When such terminals need to be plugged into circuit boards, non-standard solder joint shapes may not meet the connector's mating tolerances, leading to poor insertion. Furthermore, during insertion and removal, stress can easily concentrate on the brittle solder joints, causing cracking and ultimately affecting the long-term reliability of the connection.

[0008] Optionally, the second metal spring is positioned opposite and offset.

[0009] By adopting the above technical solution, the second metal spring of the terminal block is set opposite and staggered, which can better compress and connect the wire body. This can reduce the possibility of problems such as difficulty in accurately controlling the amount of solder and cumbersome process in traditional tin soldering methods, improve the reliability, stability and convenience of wiring, reduce the dependence on the skills of operators, and ensure the consistency of large-scale production.

[0010] Optionally, after the second metal spring is bent, the end of the second metal spring is adjacent to the opposite side of the connection area between the second metal spring and the terminal body.

[0011] By adopting the above technical solution, the pressure on the wire can be increased by bending the end to the side opposite to the connection area with the terminal body.

[0012] Optionally, the end of the second metal spring is arc-shaped.

[0013] By adopting the above technical solution, the end of the arc-shaped second metal spring can reduce damage to the wire body when it is pressed and electrically connected. It can also better adapt to the shape of the wire body during the pressing process, making the connection tighter and more stable, reducing the possibility of stress concentration leading to wire damage, and improving the connection quality and reliability of the terminal block.

[0014] Optionally, a snap-fit ​​block is provided on the side of the terminal body facing away from the cable.

[0015] By adopting the above technical solution, a snap-fit ​​block is set on the side of the terminal body facing away from the cable, which can achieve more convenient and reliable installation and fixing, reduce the possibility of irregular solder joints affecting assembly and connection reliability in the traditional tin soldering method, and improve the convenience and stability of the terminal block installation on related equipment or components.

[0016] Secondly, this application provides a terminal crimping device, which adopts the following technical solution: A terminal crimping device includes a crimping machine body, wherein the crimping machine body is provided with a crimping table; The crimping machine body is provided with a crimping block located directly above the crimping table, and the crimping machine body is provided with a power component that drives the crimping block to slide up and down; The crimping machine body is provided with a feeding section, which transmits a carrier strip carrying the terminal body toward the crimping table. The crimping machine body is also provided with a discharging section that outputs the carrier strip after the terminal body has detached. The crimping machine body is provided with a transmission mechanism, which transmits the cable section between the terminal body and the crimping block, and transmits the crimped terminal body away from the crimping table.

[0017] By adopting the above technical solution, it is possible to crimp the terminals, including the terminal body and the cable part, reducing the possibility of problems such as reliance on operator skills and cumbersome procedures in traditional soldering methods. It can also reduce the possibility of limitations such as difficulty in accurately controlling the amount of solder and irregular solder joints affecting subsequent processes and connection reliability, thus achieving efficient and reliable crimping of the terminals.

[0018] Optionally, the pressing machine body is slidably connected with lifting rollers, the lifting rollers include a first lifting roller and a second lifting roller, the pressing table is located between and adjacent to the first lifting roller and the second lifting roller, the first lifting roller is located on the side closer to the feeding part, and the lifting roller is located below the support bar and is slidably connected. The crimping machine body is rotatably connected to multiple pressing rollers, the lifting roller is located between two adjacent pressing rollers, and the pressing roller is rotatably connected to the top of the support strip; The crimping machine body is equipped with a control component that can control the rise and fall of the relative lifting rollers respectively. The crimping machine body is equipped with a controller, which is electrically connected to the control component. The side wall of the crimping block is equipped with an infrared detection element for detecting the position of the terminal body. The infrared detection element is electrically connected to the controller. When the infrared detector detects that the terminal body is located on the side of the cable section near the feed section, the controller controls the control component to drive the first lifting roller to slide downward and drive the second lifting roller to slide upward. When the infrared detector detects that the terminal body is located on the side of the cable section away from the feed section, the controller controls the control component to drive the first lifting roller to slide upward and drive the second lifting roller to slide downward.

[0019] By adopting the above technical solution, the setting of the first lifting roller and the second lifting roller can provide a certain margin for the bearing strip between the feeding section and the discharging section. When there are debris or other foreign objects generated after the terminal body falls off on the crimping table, the bearing strip will bulge due to the influence of the debris or other foreign objects, affecting the alignment accuracy between the terminal body and the cable section. At this time, by sliding the first lifting roller and the second lifting roller up and down, the bearing strip will slide, and the position of the terminal body will be adjusted to improve the alignment accuracy between the terminal body and the cable section.

[0020] Optionally, the control component includes a control cylinder and a control frame. The control cylinder is disposed on the pressing machine body and located above the support bar. The control cylinder is electrically connected to the controller. The control frame is located at the end of the piston rod of the control cylinder, the lifting roller is rotatably connected to the control frame, and the support bar slides through the control frame.

[0021] By adopting the above technical solution, and utilizing the control assembly consisting of a control cylinder and a control frame, the lifting roller can be precisely driven to rise and fall under the control of the controller.

[0022] Thirdly, this application provides a crimping method for wiring terminals, employing the following technical solution: A method for crimping a terminal block includes the following steps: S1: Feeding: Add a support bar to the feeding section to support the terminal body, and add the cable section to the transmission mechanism; S2: Material feeding, start the crimping machine body so that the feeding part conveys the terminal body to the crimping table, and the transmission mechanism transmits the cable part to the top of the terminal body; S3: Crimping, the power component controls the crimping block to crimp the cable portion to the terminal body; S4: Unloading. The transmission mechanism transports the crimped terminal body away from the support bar, and then the transmission mechanism continues to transport the terminal body to the top of the terminal body.

[0023] By adopting the above technical solution and using terminal crimping equipment, the crimping of terminals can be automated through the steps of feeding, conveying, crimping, and unloading. This reduces the reliance on operator skills associated with traditional soldering methods, solves problems such as difficulty in accurately controlling solder usage and irregular solder joints affecting assembly and insertion, improves the reliability, stability, and convenience of terminal connection, and ensures consistency in large-scale production.

[0024] In summary, this application includes at least one of the following beneficial effects: 1.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses a terminal block.

[0029] This application mainly adopts terminal blocks and crimping equipment and methods to solve the limitations of traditional soldering, thereby avoiding the limitations of traditional soldering and improving the reliability and convenience of wiring. The following is a further detailed description of this application.

[0030] Example 1 See Figure 1 and Figure 2 The terminal block provided in this application includes a terminal body 1 and a cable portion 2, wherein the cable portion 2 passes through the terminal body 1, realizing the connection between the cable portion 2 and the terminal body 1. This achieves the effect of replacing the traditional soldering method, reducing the limitations of soldering, and improving connection reliability and convenience. This is because traditional soldering has problems such as difficulty in controlling the amount of solder used and irregular solder joints affecting subsequent processes and connection reliability. This structure reduces the possibility of these problems occurring through mechanical fixing.

[0031] Specifically, the cable section 2 includes a housing 21 and a conductor 22. The conductor 22 passes through the housing 21, with a portion protruding beyond the housing 21. The housing 21 is typically made of insulating material, such as rubber, and is generally tubular in shape to protect the conductor 22 and reduce the possibility of damage from external factors. The conductor 22 is the conductor used to transmit electrical energy or signals and can be made of metals such as copper or aluminum. In practical applications, the housing 21 can also be made of insulating materials with a certain degree of elasticity, such as plastic, to better adapt to different usage environments. The material of the conductor 22 can also be selected according to specific usage requirements; for example, in applications requiring high conductivity, higher purity copper can be used.

[0032] The horizontal cross-section of the terminal body 1 is convex ("U"), and a wire groove is provided on the terminal body 1 for mounting the outer casing 21 and the wire 22. The terminal body 1 includes a first fixing structure and a second fixing structure. The first fixing structure and the second fixing structure cooperate with each other to ensure a stable connection between the cable part 2 and the terminal body 1. Specifically, the first fixing structure is used to fix the outer casing 21, and the second fixing structure is used to fix the wire 22.

[0033] The first fixing structure includes multiple first metal springs 3, which are used to press and fix the cable by bending. The first metal springs 3 are typically made of a metal material with a certain degree of elasticity, such as stainless steel. The shape of the first metal springs 3 can be sheet-like. In the initial state, the first metal springs 3 are in a relatively extended state. When the cable portion 2 is inserted into the terminal body 1, the first metal springs 3 face the outer shell 21. Then, the first metal springs 3 are bent, pressing the outer shell 21 against the terminal body 1, thus fixing the cable. In some special cases, the first metal springs 3 can also be made of materials such as copper alloys to improve their conductivity and elasticity. The arrangement of multiple first metal springs 3 can fix the cable from different directions, enhancing the stability of the fixation.

[0034] The second fixing structure includes multiple second metal springs 4, which are used to bend, compress, and electrically connect the wire 22. The second metal springs 4 are also made of a metal material with good conductivity and elasticity, such as copper. The second metal springs 4 are also sheet-shaped. When the wire 22 is inserted into the terminal body 1, bending the second metal springs 4 compresses and fixes the wire 22 to the terminal body 1, thus not only fixing the wire 22 but also establishing a good electrical connection. In practical applications, the surface of the second metal springs 4 can be treated with silver plating or other methods to further improve its conductivity. The arrangement of multiple second metal springs 4 increases the contact area with the wire 22 and improves the stability of the electrical connection.

[0035] The second metal springs 4 are arranged opposite each other and offset. After being bent, the ends of the second metal springs 4 are adjacent to the opposite side of the connection area between the second metal springs 4 and the terminal body 1. This arrangement allows the second metal springs 4 to apply pressure more evenly when pressing the wire 22, and the adjacent second metal springs 4 cooperate with each other to form an interlocking structure, improving the fixing and electrical connection effect. For example, when the wire 22 is thick, the opposite and offset second metal springs 4 can better adapt to the shape of the wire 22 and press the wire 22 from different angles.

[0036] The end of the second metal spring 4 is arc-shaped. This arc shape reduces damage to the wire 22 when it is pressed, and also allows for better contact with the surface of the wire 22, improving the stability of the electrical connection. In actual manufacturing, the radius of the arc shape can be adjusted according to factors such as the diameter of the wire 22.

[0037] A snap-fit ​​block 11 is provided on the side of the terminal body 1 facing away from the cable. The snap-fit ​​block 11 is usually made of the same material as the terminal body 1. The snap-fit ​​block 11 can be hook-shaped and used to snap-fit ​​with other components to facilitate the installation and fixation of the terminal block, such as a power strip.

[0038] The implementation principle of a terminal block in Embodiment 1 of this application is as follows: In this embodiment, the terminal block uses a first fixing structure and a second fixing structure to fix and electrically connect the outer shell 21 and the wire 22 of the cable section 2, respectively, reducing the limitations of traditional soldering methods. The arrangement of the first metal spring 3 and the second metal spring 4 makes the fixing and electrical connection more reliable and the operation relatively simple, improving production efficiency. At the same time, the relative and staggered arrangement of the second metal spring 4 and the arc-shaped structure at the end further optimize the effect of fixing and electrical connection. The snap-fit ​​block 11 facilitates the installation of the terminal block, making it more convenient in practical applications. Compared with traditional soldering methods, this terminal block can ensure the consistency of connection in large-scale production, improving the safety and performance of the entire circuit system. Furthermore, after soldering the plug-in board, the solder connects the wire and the metal terminal together, maintaining low contact resistance and stable connection under mechanical vibration and high and low temperature environments, avoiding problems with poor contact.

[0039] Example 2 See Figure 3 and Figure 4 The terminal crimping equipment provided in this application includes a crimping machine body 5, wherein the components of the crimping machine body 5 cooperate with each other to realize the automated crimping of the terminal blocks, thereby improving production efficiency and crimping quality.

[0040] Specifically, the crimping machine body 5 is equipped with a crimping table 51. The crimping table 51 is usually made of a sturdy metal material, such as steel, and its top surface is flat and smooth, used to place the terminals to be crimped. The size and shape of the crimping table 51 can be designed according to the specific size of the terminals. In some cases, the surface of the crimping table 51 can also be specially treated, such as nickel plating, to improve its wear resistance and corrosion resistance.

[0041] The crimping machine body 5 is equipped with a crimping block 58, which is located directly above the crimping table 51. The crimping machine body 5 is equipped with a power component 52 for driving the crimping block 58 to slide up and down. The crimping block 58 is made of a high-hardness metal material, such as mold steel, and its shape matches the crimping part of the terminal. The power component 52 can be a cylinder, electric push rod, hydraulic cylinder, etc. Driven by the power component 52, the crimping block 58 can accurately crimp the cable part 2 and the terminal body 1, causing the first metal spring 3 to bend and press the outer shell 21 tightly onto the terminal body 1, and the second metal spring 4 to bend and press the wire 22 tightly onto the terminal body 1. Upon completion of the crimping, the terminal body 1 detaches from the support strip. In practical applications, the type of power component 52 can be selected according to the crimping force and speed requirements. In this embodiment, the crimping process of the crimping block 58 and the crimping table 51 to achieve the crimping of the terminal body 1 and the cable part 2 is prior art and will not be described in detail here.

[0042] The crimping machine body 5 is equipped with a feeding section 53, which conveys the carrier strip carrying the terminal body 1 to the crimping table 51. The crimping machine body 5 is also equipped with a discharging section 54, through which the carrier strip after the terminal body 1 has detached is output. The feeding section 53 typically employs a conveying mechanism 55 such as a feeding roller to stably transport the carrier strip to the crimping table 51. The carrier strip is generally made of flexible metal material, allowing it to deform according to the conveying conditions. The carrier strip is used to support multiple terminal bodies 1, ensuring that the spacing between the terminal bodies 1 remains equal, facilitating mass production. During the feeding process, the feeding section 53 can be equipped with sensors or other devices to ensure accurate delivery of the carrier strip. When the feeding section 53 conveys the terminal body 1 to directly below the crimping block 58, the feeding section 53 stops conveying the terminal body 1. When the terminal body 1 is crimped with the cable section 2, the feeding section 53 resumes conveying the terminal body 1.

[0043] The crimping machine body 5 is equipped with a transmission mechanism 55, which transmits the cable portion 2 between the terminal body 1 and the crimping block 58. The transmission mechanism 55 also transmits the crimped terminal body 1 away from the crimping table 51. In this embodiment, the transmission mechanism 55 uses a robotic arm, which can accurately transmit the cable portion 2 and the crimped terminal body 1. The robotic arm has high flexibility and precision and can adapt to different production needs, so it will not be described in detail here.

[0044] See Figure 4 and Figure 5The crimping machine body 5 is slidably connected to a lifting roller 6, which includes a first lifting roller 61 and a second lifting roller 62. The crimping table 51 is located between and adjacent to the first lifting roller 61 and the second lifting roller 62. The first lifting roller 61 is located near the feeding section 53, and the lifting roller 6 is located below the support strip and is slidably connected. The lifting roller 6 is usually made of a material with a certain degree of elasticity, such as rubber. The function of the lifting roller 6 is to lift the support strip. The arrangement of the first lifting roller 61 and the second lifting roller 62 allows the support strip between the feeding section 53 and the discharging section 54 to have a certain margin. When there are debris or other foreign objects generated after the terminal body 1 falls off on the crimping table 51, the support strip will bulge due to the influence of the debris or other foreign objects, affecting the alignment accuracy between the terminal body 1 and the cable section 2. At this time, by sliding the first lifting roller 61 and the second lifting roller 62 up and down, the support strip slides, adjusting the position of the terminal body 1 and improving the alignment accuracy between the terminal body 1 and the cable section 2.

[0045] The crimping machine body 5 is rotatably connected to two sets of pressing rollers 7. Each set of pressing rollers 7 corresponds to one lifting roller 6. There are two pressing rollers 7 in each set, arranged symmetrically. Each lifting roller 6 is located between the two pressing rollers 7 in the same set. The pressing rollers 7 are rotatably connected to the top of the support strip. The pressing rollers 7 are also made of materials such as rubber. The function of the pressing rollers 7 is to press the support strip firmly, reducing the possibility of the support strip shaking or shifting during the up and down sliding of the lifting rollers 6.

[0046] The crimping machine body 5 is equipped with a control component 8, which controls the raising and lowering of the relative lifting roller 6 during operation. A controller 56 is fixedly mounted on the crimping machine body 5 and is electrically connected to the control component 8. An infrared detector 57, which detects the position of the terminal body 1, is fixedly mounted on the side wall of the crimping block 58 and is electrically connected to the controller 56. The infrared detector 57 can detect the position of the terminal body 1 in real time and transmit the signal to the controller 56. The controller 56 controls the control component 8 based on the received signal, thereby controlling the raising or lowering of the lifting roller 6.

[0047] When the infrared detector 57 detects the terminal body 1 on the side of the cable section 2 near the feed section 53, the controller 56 controls the control component 8 to drive the first lifting roller 61 to slide downwards and the second lifting roller 62 to slide upwards. When the infrared detector 57 detects the terminal body 1 on the side of the cable section 2 away from the feed section 53, the controller 56 controls the control component 8 to drive the first lifting roller 61 to slide upwards and the second lifting roller 62 to slide downwards. This control method can adjust the state of the lifting rollers 6 in real time according to the position of the terminal body 1, ensuring the smooth transmission of the carrier strip and the smooth progress of the crimping process.

[0048] The control assembly 8 includes a control cylinder 81 and a control frame 82. The control cylinder 81 is mounted and fixed to the pressing machine body 5 and located directly above the support strip. The control cylinder 81 is electrically connected to the controller 56. The control frame 82 is fixedly connected to the end of the piston rod of the control cylinder 81. The lifting roller 6 is rotatably connected to the control frame 82, and the support strip slides through the control frame 82. The control cylinder 81, controlled by the controller 56, extends and retracts the piston rod, thereby driving the control frame 82 and the lifting roller 6 to rise and fall. The control frame 82 is generally inverted "U" shaped, providing stable support for the lifting roller 6.

[0049] The implementation principle of a terminal crimping device according to Embodiment 2 of this application is as follows: The terminal crimping equipment in this embodiment achieves automated crimping of terminals through the coordinated operation of its components. The feeding section 53 and the transmission mechanism 55 ensure accurate transport of the terminal body 1 and the cable section 2, while the crimping block 58 and the power unit 52 complete the crimping operation. The lifting roller 6, the pressing roller 7, and the control component 8 ensure smooth transport of the carrier strip, and the cooperation of the infrared detector 57 and the controller 56 enables precise control of the crimping process. Compared with traditional manual crimping methods, this improves production efficiency and crimping quality, reduces errors caused by manual operation, and ensures product consistency.

[0050] Example 3 See Figure 6 The crimping method for the wiring terminals provided in this application includes the following steps: Step 1: Loading. The operator replenishes the feeding section 53 with carrier strips carrying the terminal bodies 1 and the transmission mechanism 55 with cable sections 2. In this step, the operator places the carrier strips carrying multiple terminal bodies 1 onto the feeding section 53 and simultaneously places the cable sections 2 onto the transmission mechanism 55. The feeding section 53 can be in the form of a feeding roller or hopper to facilitate the storage and replenishment of carrier strips. The transmission mechanism 55 can be equipped with a dedicated storage area for storing the cable sections 2. When replenishing the carrier strips and cable sections 2, it is necessary to ensure their accurate placement for subsequent conveying and crimping operations.

[0051] Step Two: Material Feeding. Start the crimping machine 5, causing the feeding unit 53 to feed the terminal body 1 to the crimping table 51. The transmission mechanism 55 then transmits the cable part 2 above the terminal body 1. The feeding unit 53 transports the carrier strip to the crimping table 51 via a conveyor belt or similar means, while the transmission mechanism 55 accurately places the cable part 2 above the terminal body 1 using a robotic arm or similar means. During the conveying process, it is necessary to ensure the speed and stability of the conveying to reduce the possibility of the terminal body 1 or the cable part 2 shifting or falling off.

[0052] Step 3: Crimping. The power unit 52 controls the crimping block 58 to crimp the cable portion 2 to the terminal body 1. When a crimping command is received, the power unit 52 drives the crimping block 58 to move downwards, crimping the cable portion 2 and the terminal body 1. During the crimping process, it is necessary to control the crimping force and time to ensure the quality of the crimping. The crimping force can be monitored in real time by setting up devices such as pressure sensors.

[0053] Step 4: Unloading. The transmission mechanism 55 transports the crimped terminal body 1 away from the carrier bar, and then continues to transport the terminal body 1 above it. The transmission mechanism 55 conveys the crimped terminal body 1 that has detached from the carrier bar to a designated location for collection or subsequent processing. Then, the transmission mechanism 55 transports the new cable part 2 above the terminal body 1 again, ready for the next crimping operation. During the unloading process, care must be taken to avoid damaging the crimped terminal body 1.

[0054] The implementation principle of the crimping method for a terminal block in Embodiment 3 of this application is as follows: This embodiment of the terminal crimping method automates the terminal crimping process through four steps: loading, conveying, crimping, and unloading. Each step works in tandem to form a complete production flow. Compared to traditional manual crimping methods, this method improves production efficiency, reduces human error, and ensures consistent crimping quality. Furthermore, this method can be adjusted to meet different production needs, exhibiting strong adaptability and flexibility.

[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.
