Description

Technical Field

[0001] This utility model relates to the field of crimping fixture technology, specifically to a crimping tool. Background Technology

[0002] Existing manual crimping fixtures typically include a base with a quick-release clamp for applying force. The quick-release clamp includes a crimping handle, and the crimping plate of the crimping handle is slidably connected to two guide posts. The operator places the PCB board and the crimping components into the base, and uses the crimping handle to move the crimping plate to press the pins of the crimping components onto the components on the PCB board.

[0003] However, in the prior art, the two guide posts are often directly set on the middle of both sides of the crimping plate, such as the wire harness terminal crimping fixture with announcement number CN220291322U. The spacing between the two guide posts limits the size of the PCB board and the crimping components, which makes the existing manual crimping fixture generally unsuitable for large PCB boards and crimping components. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a crimping fixture that solves the problem that the spacing between the two guide posts in the existing manual crimping fixture limits the size of the PCB board and the crimped components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A crimping fixture is provided, including a base, a positioning plate for fixing a PCB board and crimping components is provided on the top surface of the base; two bent plates are symmetrically arranged on both sides of the top surface of the base, each bent plate including an integrally formed vertical plate and an inclined plate; a support plate is provided between the two vertical plates, and two guide posts are symmetrically arranged between the support plate and the base; a fixing plate is vertically arranged between the two inclined plates, and a quick clamp is fixed in the middle of the fixing plate. The quick clamp includes a crimping handle and a crimping plate provided on the crimping handle. The crimping plate has a T-shaped plate structure, and the two sides of the flange of the crimping plate are slidably connected to the two guide posts respectively. At least one crimping block is provided on the bottom of the web of the crimping plate.

[0007] In this solution, by setting the pressing plate as a T-shaped plate structure and sliding two guide posts on the flanges of the pressing plate, the cooperation between the pressing plate and the bending plate fully exposes the space below the web of the pressing plate, without restricting the size of the pressing components and the PCB board. Furthermore, the bending plate provides a mounting distance away from the guide posts for the pressing handle, allowing the pressing handle to be fixed on the web of the pressing plate. This makes the pressing plate more evenly stressed and better drives the pressing block to press the pins on the pressing components into the corresponding positions on the PCB board.

[0008] Furthermore, the tops of both inclined vertical plates are integrally formed with horizontal plates, and the two sides of the fixing plate are bolted to the sides of the two horizontal plates respectively. The horizontal plates further provide an installation distance for the crimping handle away from the guide post.

[0009] Furthermore, the tilt angle of each inclined vertical plate is 45°. This tilt angle of the vertical plates facilitates the transmission of the pressing force.

[0010] Furthermore, sliding bearings are bolted to both sides of the wing plate, with two sliding bearings respectively fitted onto two guide posts. The installation of sliding bearings not only reduces frictional resistance and improves sliding smoothness, but also increases the precision and stability during the pressing process, preventing the pressing plate from shaking or shifting during movement.

[0011] Furthermore, two crimping blocks are symmetrically arranged on the web. This symmetrical design makes the crimping process more uniform, allowing multiple crimping points to be processed simultaneously, thus improving crimping efficiency.

[0012] Furthermore, the positioning plate is fixed to the base with bolts. The positioning plate has a first recess for fixing the PCB board and two second recesses for fixing the crimped components. Each second recess has a crimping pad near the edge of the first recess for placing the crimped component leads. The two crimping pads are located directly below the two crimping blocks. The crimping pads are made of rigid plastic or metal, providing more stable support and guidance, which helps improve the quality and consistency of the crimped products.

[0013] Furthermore, a locating pin is provided on both sides of the base, and locating holes are provided on both pressing blocks. The two locating pins are respectively clearance-fitted into the two locating holes. The locating pins and locating holes ensure the precise positioning of the pressing blocks during movement, further improving the accuracy and stability of the pressing process.

[0014] This utility model discloses a crimping tool, the beneficial effects of which are:

[0015] This invention designs the pressing plate as a T-shaped plate structure and slides two guide posts on the flanges of the pressing plate, thus fully exposing the space below the web of the pressing plate and not restricting the size of the pressing components and PCB board. Simultaneously, the bending plate provides a distance from the guide posts for the pressing handle, resulting in more even force distribution on the pressing plate and better enabling the pressing block to press the pins of the pressing components into the corresponding positions on the PCB board.

Detailed Implementation

[0021] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0022] In the prior art, the two guide posts 31 are usually directly set on the middle of both sides of the pressing plate 52. The distance between the two guide posts 31 limits the size of the PCB board and the pressing components, which makes the existing manual pressing fixture generally unsuitable for large PCB boards and pressing components. In order to solve the problem that the distance between the two guide posts 31 limits the size of the PCB board and pressing components, this application sets the pressing plate 52 as a T-shaped plate structure and slides the two guide posts 31 on the wing plate 521 of the pressing plate 52 respectively. Thus, the cooperation between the pressing plate 52 and the bending plate 200 fully exposes the space under the web plate 522 of the pressing plate 52, and does not limit the size of the pressing components and the PCB board, thus achieving the technical effect of being suitable for large PCB boards and pressing components.

[0023] This application provides a crimping tool, with reference to... Figure 1 and Figure 2The system includes a base 100, on the top surface of which is a positioning plate 11 for fixing a PCB board and crimping components. The positioning plate 11 is fixed to the base 100 by bolts. The positioning plate 11 has a first recess 111 for fixing the PCB board and two second recesses 112 for fixing the crimping components. Each second recess 112 has a crimping pad 113 near the edge of the first recess 111 for placing the pins of the crimping components. The two crimping pads 113 are located directly below the two crimping blocks 523. The crimping pads 113 are made of rigid plastic or metal, providing more stable support and guidance, which helps improve the quality and consistency of the crimped products.

[0024] Two bent plates 200 are symmetrically arranged on both sides of the top surface of the base 100. Each bent plate 200 includes an integrally formed vertical plate 21 and an inclined plate 22. A support plate 300 is arranged between the two vertical plates 21, and two guide posts 31 are symmetrically arranged between the support plate 300 and the base 100. A fixing plate 400 is vertically arranged between the two inclined plates 22. A quick clamp 500 is fixed in the middle of the fixing plate 400. The quick clamp 500 includes a pressing handle 51 and a pressing plate 52 arranged on the pressing handle 51. The pressing plate 52 has a T-shaped plate structure. The two sides of the flange 521 of the pressing plate 52 are slidably connected to the two guide posts 31 respectively. Two pressing blocks 523 are arranged on the bottom of the web plate 522 of the pressing plate 52.

[0025] In this embodiment, the tilt angle of each inclined vertical plate 22 is 45°. This tilt angle of the inclined vertical plate 22 is conducive to the transmission of the pressing force.

[0026] To further increase the installation distance of the crimp handle 51 from the guide post 31, the tops of both inclined vertical plates 22 are integrally formed with horizontal plates 23, and the two sides of the fixing plate 400 are respectively bolted to the sides of the two horizontal plates 23.

[0027] For the specific sliding structure between the pressure plate 52 and the guide post 31, please refer to Figure 3 and Figure 4 Sliding bearings 32 are bolted to both sides of the wing plate 521, and the two sliding bearings 32 are respectively sleeved on the two guide posts 31. The installation of sliding bearings 32 not only reduces frictional resistance and improves the smoothness of sliding, but also increases the accuracy and stability during the pressing process, preventing the pressing plate 52 from shaking or shifting during movement.

[0028] To further improve the accuracy and stability of crimping, refer to Figure 1 and Figure 4 A positioning pin 114 is provided on both sides of the base 100, and positioning holes are provided on both pressing blocks 523. The two positioning pins 114 are respectively fitted with the two positioning holes with clearance.

[0029] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent.
