[0002] Electronic components are the basic building blocks of electronic circuits, used to generate, transmit, process, store, or convert electrical signals. They are the foundation of modern electronic devices; everything from tiny chips to complex systems relies on these components.

[0003] Currently, electronic components with pins generally require the pins to be bent during use. However, there is a lack of fixtures for bending the pins of electronic components, resulting in a lack of precision in manual bending and an inability to control the bending distance. This causes the pins to be unable to be accurately inserted into the corresponding pads, affecting the accuracy and standardization of subsequent installation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bending fixture for electronic components, which can position electronic components and provide measurement and adjustment functions, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a bending fixture for electronic components, including a positioning seat and an electronic component to be bent. The positioning seat is provided with an arc-shaped groove, and clamping plates are provided at both ends of the positioning seat. A bending plate is provided parallel to the clamping plate on the outer side of the clamping plate. The clamping plate and the bending plate are provided with positioning grooves at the positions directly opposite the arc-shaped groove. The outer shell of the electronic component is disposed in the arc-shaped groove, and the pins of the electronic component are disposed through the positioning grooves. An adjustment mechanism for adjusting the distance between the bending plates is installed between the clamping plate and the bending plate.

[0006] As a preferred technical solution, the adjustment mechanism includes a lead screw, a bearing, and a gripping rod. The bearings are all embedded and installed on the outer side of the clamping plate. The bending plate has a lead screw hole opposite to the inner ring of the bearing. The lead screw is threaded into the lead screw hole. One end of the lead screw is installed in the inner ring of the bearing, and the other end is fixedly connected to the gripping rod.

[0007] As a preferred technical solution, the adjustment mechanism also includes a positioning plate. The positioning seat is provided with a first adjustment groove on one side of the arc groove. The clamping plate and the bending plate are provided with a second adjustment groove opposite to the first adjustment groove. One end of the positioning plate is installed in the second adjustment groove of the bending plate, and the other end of the positioning plate extends through the second adjustment groove of the clamping plate to the first adjustment groove of the positioning seat. Sliding grooves are provided on both sides of the first and second adjustment grooves. Sliding strips are formed by protrusions on both sides of the positioning plate. The sliding strips are slidably disposed in the sliding grooves. Scales are provided on the surface of the positioning plate.

[0008] As a preferred technical solution, both ends of the positioning seat are provided with multiple positioning holes, and positioning pins are inserted into the positioning holes. One end of each positioning pin extends to the outside and is installed on the clamping plate. The other end of each positioning pin is equipped with a compression spring, and the other end of each compression spring is installed on the inner wall of the positioning hole. The cross-sections of the positioning holes and positioning pins are both rectangular.

[0009] As a preferred technical solution, a pressure plate is mounted on the surface of the positioning seat via a hinge. The end of the pressure plate away from the hinge forms a "C"-shaped covering. The covering is fitted onto the outer shell of the electronic component and is set to abut against the outer shell of the electronic component. The hinge is a torsion spring hinge.

[0010] As a preferred technical solution, the opposite surfaces of the clamping plates are arranged to abut against the end face of the outer casing of the electronic component.

[0011] As a preferred technical solution, the positioning groove of the bending plate is provided with an arc-shaped guide section.

[0012] The beneficial effects of this utility model are: the structure of this utility model is simple, the shell of the electronic component can be put into the arc-shaped groove, and the clamping plates on both sides can be pulled outward. The return of the compression spring can make the clamping plates abut against the two ends of the shell. Combined with the pressure plate, the electronic component can be positioned. The distance of the bending plate can be adjusted by the adjustment mechanism, and the required bending distance can be known by the scale. After the pin is bent downward with the guide part, it can form a standard U-shaped structure and match the distance of the corresponding solder pad, which increases the standardization and accuracy of subsequent installation.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a bending fixture for electronic components according to this utility model includes a positioning seat 1 and an electronic component 4 to be bent. The positioning seat 1 is provided with an arc-shaped groove 17. The two ends of the positioning seat 1 are provided with clamping plates 2. The outer side of the clamping plates 2 is provided with bending plates 3 arranged parallel to them. The clamping plates 2 and bending plates 3 are provided with positioning grooves 12 opposite to the arc-shaped groove 17. The outer shell of the electronic component 4 is disposed in the arc-shaped groove 17. The pins 5 of the electronic component 4 are all disposed through the positioning grooves 12. An adjustment mechanism for adjusting the distance between the clamping plates 2 and the bending plates 3 is installed between them.

[0020] In this embodiment, the adjustment mechanism includes a lead screw 10, a bearing, and a gripping rod 11. The bearings are embedded on the outer side of the clamping plate 2. The bending plate 3 has a lead screw hole opposite to the inner ring of the bearing. The lead screw 10 is threaded into the lead screw hole. One end of the lead screw 10 is installed in the inner ring of the bearing, and the other end is fixedly connected to the gripping rod 11.

[0021] In this embodiment, the adjustment mechanism also includes a positioning plate 6. The positioning seat 1 is provided with a first adjustment groove 14 on one side of the arc groove 17. The clamping plate 2 and the bending plate 3 are provided with a second adjustment groove 8 opposite to the first adjustment groove 14. One end of the positioning plate 6 is installed in the second adjustment groove 8 of the bending plate 3. The other end of the positioning plate 6 extends through the second adjustment groove 8 on the clamping plate 2 to the first adjustment groove 14 of the positioning seat 1. Slide grooves are provided on both sides of the first adjustment groove 14 and the second adjustment groove 8. Slide strips 15 are protruded on both sides of the positioning plate 6. The slide strips 15 are slidably disposed in the slide grooves. Scales are provided on the surface of the positioning plate 6.

[0022] In this embodiment, both ends of the positioning base 1 are provided with multiple positioning holes 16, and positioning pins 9 are inserted into each positioning hole 16. One end of each positioning pin 9 extends to the outside and is installed on the clamping plate 2. The other end of each positioning pin 9 is installed with a compression spring. The other end of each compression spring is installed on the inner wall surface of the positioning hole 16. The cross-section of the positioning hole 16 and the positioning pin is rectangular. The positioning hole is a countersunk hole, so it does not penetrate the positioning base, so that the other end of the compression spring can be smoothly fixed on the inner wall surface at the deepest part of the positioning hole.

[0023] In this embodiment, a pressure plate 7 is mounted on the surface of the positioning base 1 via a hinge. The end of the pressure plate 7 away from the hinge forms a "C"-shaped covering. The covering is fitted onto the outer shell of the electronic component 4 and is set to abut against the outer shell of the electronic component 4. The hinge is a torsion spring hinge. The torsion of the torsion spring hinge can cause the pressure plate to rotate toward the positioning base until it presses against the outer shell of the electronic component.

[0024] In this embodiment, the opposite surfaces of the clamping plate 2 are both in contact with the end face of the outer shell of the electronic component 4, so that the outer shell can be clamped and fixed inward by the clamping plate.

[0025] In this embodiment, the positioning groove 12 of the bending plate 3 is provided with an arc-shaped guide portion 13, so that the pin can be bent downward with the guide portion as the center.

[0026] In use, pull the clamping plate outward and open the pressure plate to place the electronic component's casing into the arc-shaped groove. After releasing the pressure plate, the torsion of the torsion spring hinge causes the pressure plate to rotate in the opposite direction until the cover rests against the casing, thereby pressing the electronic component's casing firmly onto the positioning seat. After releasing the clamping plate, the return of the compression spring pushes the clamping plate inward, causing the opposite surfaces of the clamping plate to press against both ends of the casing, thereby positioning the electronic component. The pins on the electronic components pass through the positioning grooves, and the bending distance can be adjusted according to the distance between the subsequent pads. During adjustment, the screw is rotated by holding the lever, and the rotation of the screw drives the bending plate, which moves along the first adjustment groove. Combined with the position on the positioning plate, the distance between the bending point and the outer shell can be known to ensure that the bent pin can be accurately inserted into the corresponding pad. When bending, the pin is pressed down by the finger, so that the pin bends downward around the guide part to ensure the quality of the bending.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
