Description

Technical Field

[0001] This invention relates to the field of terminal fixture technology, and in particular to a terminal fixing device. Background Technology

[0002] Currently, most wires in the charging vehicle wiring harness are typically crimped with individual tubular terminals, ring terminals, or other single terminals, rather than integrated connectors. Furthermore, they need to be processed independently for different circuits before being connected to the final assembly line. In traditional production methods, these individual wires are manually attached one by one to the assembly plate, relying on workers for assembly. However, this manual method results in low overall production efficiency and high labor costs. Additionally, after final assembly, two people must work together to use a multimeter to check continuity, requiring a high degree of cooperation from the workers.

[0003] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a terminal fixing device that can be used for the insertion of different types of terminals and converts the output of different types of terminals into a unified interface to facilitate continuity testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A terminal fixing device includes an insertion base and a fixture body. The bottom of the fixture body is provided with a fixture base, which is magnetically connected to the insertion base. The fixture body is provided with a plurality of clamping components, and each clamping component is provided with an openable slot for clamping a terminal. The output end of the clamping component is electrically connected to the fixture base.

[0006] In the terminal fixing device, at least one magnet is provided at the bottom of the fixture base, and the magnet is magnetically connected to the insertion base.

[0007] In the terminal fixing device, the fixture base is provided with a positioning groove, the insertion base is provided with a positioning protrusion that cooperates with the positioning groove, the positioning groove is provided with a positioning pin, and the positioning protrusion is provided with a pin hole that cooperates with the positioning pin.

[0008] In the terminal fixing device, the fixture body is provided with a first mounting area and a second mounting area, which are separated and connected by an adjustment component. The adjustment component is movably connected to the fixture body. Both the first mounting area and the second mounting area are provided with multiple mounting slots. The clamping component is disposed in the mounting slot and is kinetically connected to the adjustment component. The slot is located between the clamping component and the adjustment component. The adjustment component is used to adjust the opening and closing state of the slot.

[0009] In the terminal fixing device, the clamping assembly includes an end spring piece. Both the first mounting area and the second mounting area are provided with spring plate pressure plates on the side away from the adjusting assembly. The end spring piece is connected to the spring plate pressure plates by a connecting pin. One side of the end spring piece abuts against the adjusting assembly. The slot is located between the end spring piece and the adjusting assembly.

[0010] In the terminal fixing device, the terminal bullet includes a first pressure plate and a second pressure plate. One end of the first pressure plate and the second pressure plate are connected by an electrical connecting piece. A compression opening is formed between the other ends of the first pressure plate and the second pressure plate. The second pressure plate abuts against the adjusting component, and the slot is located between the second pressure plate and the adjusting component.

[0011] In the terminal fixing device, the first pressure plate extends a slanted card towards the slot, the slanted card abuts against the spring plate, and the end of the spring plate near the slanted card is provided with a slanted wall adapted to the slanted card.

[0012] In the terminal fixing device, the fixture body is provided with a first insertion hole corresponding to the position of each electrical connection piece, and the fixture base is provided with a second insertion hole corresponding to the position of the first insertion hole.

[0013] In the terminal fixing device, the adjusting component includes a locking tongue, which is located between two upper and lower second pressure plates. The bottom of the locking tongue is connected to the fixture body via at least one spring. Guide grooves are provided on both sides of the locking tongue. A locking pin is provided on the fixture body corresponding to the position of the guide groove. The guide groove and the locking pin are slidably connected.

[0014] In the terminal fixing device, the second pressure plate has an arc-shaped portion at one end near the slot, and the locking tongue has a release slope corresponding to the position of the arc-shaped portion.

[0015] Beneficial effects: This invention provides a terminal fixing device in which the fixture base and the insertion base are connected by magnetism. The attraction and repulsion of the magnets achieve connection and fixation, making the connection operation more convenient. In actual operation, when installing or removing the fixture body, no complicated tools are needed; the connection and separation can be completed quickly solely by magnetic attraction. This not only improves operational efficiency but also ensures the stability of the connection and reduces the occurrence of loosening problems.

[0016] The fixture body contains multiple clamping components, which are rationally distributed to secure terminals of different models. Each clamping component is equipped with an openable and closable slot. When securing a terminal, inserting the terminal into the slot and closing the slot keeps the terminal stable and prevents displacement or detachment.

[0017] The output end of the clamping component is electrically connected to the fixture base, which can transmit the electrical signal of the terminal to the fixture base, providing a signal channel for operations such as continuity testing, and converting the output of different types of terminals into a unified interface, making it convenient for testing equipment to perform testing.

Detailed Implementation

[0020] This invention provides a terminal fixing device. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0021] In the description of this invention, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this invention based on the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0022] Please see Figures 1 to 4 This invention provides a terminal fixing device, including an insertion base 1 and a fixture body 2. A fixture base 3 is disposed at the bottom of the fixture body 2, and the fixture base 3 is magnetically connected to the insertion base 1. Multiple clamping components 4 are disposed within the fixture body 2, and each clamping component 4 is provided with an openable and closable slot 5 for clamping a terminal 7. The output end of the clamping component 4 is electrically connected to the fixture base 3. The fixture base 3 and the insertion base 1 cooperate with each other through a magnetic connection, utilizing the attraction and repulsion forces of magnets to achieve connection and fixation, making the connection between the fixture base 3 and the insertion base 1 more convenient. In actual operation, when it is necessary to install or remove the fixture body 2, no other complex tools are needed; the connection and separation can be quickly completed solely by magnetic attraction, greatly improving operational efficiency while ensuring the stability of the connection and reducing various problems that may arise due to loose connections. Multiple clamping components 4 are arranged within the fixture body 2 in a rational layout to effectively fix terminals 7 of different models. Each clamping component 4 is equipped with an openable and closable slot 5. When it is necessary to fix the terminal 7, the terminal 7 is inserted into the slot 5 and the slot 5 is closed, thereby clamping the terminal 7 tightly within it, ensuring that the terminal 7 remains stable during subsequent testing and other operations, and will not shift or fall off. The output end of the clamping component 4 is electrically connected to the fixture base 3, which can transmit the electrical signal on the terminal 7 to the fixture base 3 through the clamping component 4, thereby providing a signal transmission channel for subsequent continuity testing and other operations. This connection method allows the output of different models of terminals 7 to be converted into a unified interface for subsequent testing equipment.

[0023] like Figures 1 to 4As shown, the bottom of the fixture base 3 is provided with at least one magnet part 31, which is magnetically connected to the insertion base 1. It should be noted that the magnet part 31 can be made of existing permanent magnet materials, such as neodymium iron boron magnets, which have a high magnetic energy product and can provide strong magnetic force.

[0024] In this embodiment, the magnet 31 can be a magnet block embedded in the bottom of the fixture base 3, or a groove can be formed in the bottom of the fixture base 3 to attach or snap a magnet piece into the groove. The insertion base 1 is made of a metal material that can be attracted by a magnet, such as iron, cobalt, or nickel, to ensure effective magnetic attraction between it and the magnet 31. This magnetic connection method allows the fixture base 3 to be easily and quickly installed on the insertion base 1. During the use of the device, the operator only needs to bring the fixture base 3 close to the insertion base 1, and the magnetic force of the magnet 31 will quickly and tightly attract the two together, without the need for additional fixing bolts or complex connection structures, greatly improving installation efficiency. At the same time, when it is necessary to replace the fixture body 2 or maintain the device, the fixture base 3 can be easily separated from the insertion base 1, enhancing the operability of the device.

[0025] like Figures 1 to 4 As shown, the fixture base 3 is further provided with a positioning groove 32, and the insertion base 1 is provided with a positioning protrusion 11 that mates with the positioning groove 32. A positioning pin 33 is provided within the positioning groove 32, and a pin hole 12 that mates with the positioning pin 33 is provided on the positioning protrusion 11. In this embodiment, the shapes of the positioning groove 32 and the positioning protrusion 11 can be designed in various forms according to actual needs, such as I-shaped, rectangular, circular, or dovetail-shaped. The engagement of the positioning pin 33 with the pin hole 12 enables more precise positioning. The positioning pin 33 is generally a cylindrical pin, and its material can be high-hardness alloy steel to ensure that it is not easily deformed during frequent insertion and removal. When installing the fixture base 3, first align the positioning protrusion 11 with the positioning groove 32, and then gently press down on the fixture base 3 to insert the positioning pin 33 into the pin hole 12, completing the positioning. The engagement of the positioning groove 32 with the positioning protrusion 11 and the engagement of the positioning pin 33 with the insertion hole 12 can effectively limit the lateral and longitudinal displacement of the fixture base 3 on the insertion base 1, prevent the fixture base 3 from shaking or shifting during use, ensure the stability of the terminal fixing device during operation, and thus improve the accuracy of terminal 7 fixing and testing.

[0026] like Figures 1 to 4As shown, further, the fixture body 2 is provided with a first mounting area and a second mounting area, which are connected and separated by an adjusting component 6. The adjusting component 6 is movably connected to the fixture body 2. Both the first and second mounting areas are provided with multiple mounting slots 21. The clamping component 4 is disposed in the mounting slot 21 and is kinetically connected to the adjusting component 6. The slot 5 is located between the clamping component 4 and the adjusting component 6. The adjusting component 6 is used to adjust the opening and closing state of the slot 5. Through the above configuration, the adjusting component 6 can move flexibly within the fixture body 2, thereby effectively adjusting the opening and closing state of the slot 5. For example, the adjusting component 6 can adopt a slide rail and slider connection method. A slide rail is provided on the fixture body 2, and a matching slider is installed on the adjusting component 6. In this way, the adjusting component 6 can move smoothly along the slide rail, ensuring stability and accuracy during the adjustment process. When the adjusting component 6 moves, it adjusts the gap between itself and the clamping component 4, thereby adjusting the opening and closing state of the slot 5. Because different types of terminals 7 vary in size and shape, traditional fixing slots 5 cannot meet diverse needs. This application, through the cooperation of adjusting component 6 and clamping component 4, allows for flexible adjustment of the size and shape of the slot 5 according to the actual situation of the terminal 7, achieving effective clamping of different types of terminals 7. Whether it is a small tubular terminal or a large annular terminal, the adjusting component 6 can precisely adapt the slot 5 to the size of the terminal 7, ensuring the stability and reliability of the terminal 7 during the fixing process, greatly improving the versatility and practicality of the terminal fixing device. Furthermore, by dividing the fixture body 2 into sections, it is also convenient for users to insert different terminals 7 in separate sections.

[0027] like Figures 1 to 4 As shown, the clamping assembly 4 further includes an end spring piece 41. Both the first mounting area and the second mounting area have spring plates 22 on their sides away from the adjusting assembly 6. The end spring piece 41 is connected to the spring plate 22 via a connecting pin 42. One side of the end spring piece 41 abuts against the adjusting assembly 6. The slot 5 is located between the end spring piece 41 and the adjusting assembly 6. The connection via the positioning pin 33 provides a certain degree of flexibility to the end spring piece 41, allowing it to adaptively adjust the clamping force according to the shape of different terminals 7. Furthermore, the connection via the connecting pin 42 facilitates the replacement of the end spring piece 41, enabling it to be arranged according to different terminal 7 requirements, satisfying the insertion needs of different terminals 7 such as tubular, annular, and U-shaped terminals 7.

[0028] In one embodiment, an identification layer is provided on the terminal bullet piece 41; the identification layer allows the user to quickly identify the type of terminal 7, effectively reducing the possibility of incorrect terminal 7 installation.

[0029] Specifically, the terminal bullet piece 41 includes a first pressing piece 411 and a second pressing piece 412. One end of the first pressing piece 411 and the second pressing piece 412 are connected by an electrical connector 413. A compression opening is formed between the other ends of the first pressing piece 411 and the second pressing piece 412. The second pressing piece 412 abuts against the adjusting component 6, and the slot 5 is located between the second pressing piece 412 and the adjusting component 6. The electrical connector 413 ensures the electrical connection between the first pressing piece 411 and the second pressing piece 412. When the adjusting component 6 is activated, it pushes the second pressing piece 412, causing the compression opening to deform, thereby opening and closing the slot 5. When the adjusting component 6 moves towards the second pressing piece 412, the second pressing piece 412 is pushed, the compression opening becomes smaller, the slot 5 closes, and the terminal 7 is tightly clamped. Conversely, when the adjusting component 6 moves away from the second pressing piece 412, the compression opening becomes larger, the slot 5 opens, and the terminal 7 can be loaded and unloaded.

[0030] In this embodiment, the first pressure plate 411 extends towards the slot 5 with a slanted card 414. The slanted card 414 abuts against the spring plate 22, and the end of the spring plate 22 near the slanted card 414 is provided with a slanted wall 221 adapted to the slanted card 414. When the end spring plate 41 presses against the terminal 7, the slanted card 414 generates an additional pressure component under the action of the slanted wall 221 of the spring plate 22. This component increases the pressing force of the first pressure plate 411 on the terminal 7, thereby improving the stability of the terminal 7. At the same time, the cooperation between the slanted card 414 and the slanted wall 221 can also play a certain guiding role. During the opening and closing of the slot 5, it guides the movement trajectory of the end spring plate 41, ensuring that the slot 5 can accurately clamp the terminal 7, reducing problems such as the terminal 7 not being securely fixed due to positional deviation, and allowing the end spring plate 41 to deform smoothly under pressure.

[0031] like Figures 1 to 4As shown, further, the fixture body 2 is provided with a first connector hole 23 corresponding to the position of each electrical connector 413, and the fixture base 3 is provided with a second connector hole 34 corresponding to the position of the first connector hole 23. When different types of terminals 7 are clamped in the slot 5, the electrical connector 413 of the terminal bullet 41 is electrically connected to the first connector hole 23. This connection method can adopt a common plug-in connection, using the first connector hole 23 and the second connector hole 34 to connect the electrical connector 413 to the pin of the detection connector 8, thereby realizing the transmission of electrical signals. The outputs of different types of terminals 7 are converted into a unified interface through the first connector hole 23, the second connector hole 34, and the intermediate conductive line, which facilitates the detection equipment to perform detection. During continuity testing, the test connector 8 inputs a test signal to the terminal fixing device through the second connector 34. The test signal passes sequentially through the second connector 34, the first connector 23, and the electrical connecting piece 413, and is then transmitted to the terminal 7 via the end spring piece 41. If the connection between the terminal 7 and the end spring piece 41, and between the end spring piece 41 and the electrical connecting piece 413, is normal, and the conductive lines within the fixture body 2 are fault-free, the test signal can be transmitted smoothly, and the testing equipment can detect the corresponding signal feedback, thereby determining whether the continuity between the terminal 7 and the device is good. The setting and effective cooperation of the first connector 23 and the second connector 34 provide a reliable electrical connection channel for realizing the continuity testing function of the terminal fixing device, greatly improving the efficiency and accuracy of the test, and ensuring effective control over the connection quality of the terminal 7 during the production of the charging vehicle wiring harness.

[0032] like Figures 1 to 4 As shown, the adjusting component 6 further includes a locking tongue 61 located between two upper and lower second pressure plates 412. The bottom of the locking tongue 61 is connected to the fixture body 2 via at least one spring 62. Guide grooves 63 are respectively provided on both sides of the locking tongue 61. A locking pin 64 is provided on the fixture body 2 corresponding to the position of the guide groove 63. The guide groove 63 and the locking pin 64 are slidably connected. The guide groove 63 and the locking pin 64 are slidably engaged, allowing the locking tongue 61 to move along the insertion direction of the terminal 7. When an external force is applied to the locking tongue 61, the locking tongue 61 compresses the spring 62 and moves into the fixture body 2, thereby releasing the pressure on the second pressure plate 412 and opening the slot 5 to facilitate the insertion of the terminal 7. After the external force is removed, the spring 62 pushes the locking tongue 61 back to its original position, causing the locking tongue 61 to press against the second pressure plate 412, clamping the terminal 7 between the second pressure plate 412 and the locking tongue 61 (i.e., in the slot 5).

[0033] In this embodiment, the second pressure plate 412 has an arcuate portion 415 at one end near the slot 5, and the locking tongue 61 has a release ramp 611 corresponding to the position of the arcuate portion 415. When the arcuate portion 415 abuts against the body of the locking tongue 61, the slot 5 is in a closed state; when it is necessary to remove the terminal 7, the user presses the locking tongue 61 to make the release ramp 611 reach the position of the arcuate portion 415, making the slot 5 open, and then the user can remove the terminal 7 from the slot 5; by setting the release ramp 611, the removal and installation of the terminal 7 is more convenient and smooth.

[0034] In summary, the fixture base 3 and the insertion base 1 are magnetically connected, utilizing magnetic attraction and repulsion to achieve a secure connection, making the connection more convenient. In actual operation, installing or removing the fixture body 2 requires no complex tools; magnetic attraction alone allows for quick connection and separation, improving operational efficiency, ensuring a stable connection, and reducing loosening issues. Multiple clamping components 4 are arranged within the fixture body 2, rationally distributed to secure different types of terminals 7. Each clamping component 4 has an openable slot 5; when securing the terminal 7, it is inserted into the slot 5 and closed to stabilize the terminal 7, preventing displacement or detachment. The output end of the clamping component 4 is electrically connected to the fixture base 3, transmitting the electrical signal from the terminal 7 to the fixture base 3, providing a signal channel for continuity testing, etc., converting the output of different types of terminals 7 into a unified interface for easy testing by testing equipment.
