[0001] The invention relates to the technical field of electronic components, and in particular to an electronic component fixing foot with a barbed structure. Background Art

[0002] In the current era of electronic products, PCB (printed circuit board) is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use printed circuit boards to make electrical interconnections between various electronic components. Therefore, there are multiple connectors for transmitting current and signals, and multiple structural parts for fixing the printed circuit board to pull or support other electronic components. However, these electronic components such as connectors and structural parts need to be stably plugged into the openings of the printed circuit board through fixing feet.

[0003] The fixing feet of existing electronic components are generally used for fixing openings. This type of fixing feet is mostly fixed and cannot be adjusted. Each electronic component has its own matching fixing feet and openings. When installing electronic components with very different sizes, we can replace the fixing feet. However, many small electronic components have small differences in size. If the fixing feet are replaced when installing and fixing them, it will greatly waste installation and fixing time, reduce work efficiency, and the operation process is also cumbersome.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. An electronic component fixing foot with a barbed structure. When the electronic component is to be fixed, the fixing rod is first inserted into the opening through the triangular plate. When the opening is smaller than the original fixing foot specification, the four groups of fixing rods are simultaneously contracted inward by the opening. At this time, the fixing rod squeezes the first spring and reduces the diameter until it can be fixed through the opening. When the fixing rod contracts, it drives the moving plate to move. When the moving plate contacts the top rod, the moving plate is resisted by the top rod and no longer moves inward. At this time, the moving plate and the anti-slip plate together play a role of reinforcement and stability, so that the fixing foot can adapt to more openings, while ensuring the stability of the fixing foot.

[0019] 2. This kind of electronic component fixing foot with a barbed structure, when the electronic component needs to be fixed, press the barbed plate to make the fixing rod pass through the opening, and then release the barbed plate. The barbed plate will pop out under the elastic force of the torsion spring. At this time, the barbed plate and the spike cone jointly play a limiting role to prevent the fixing rod from sliding out, making the structure more stable. BRIEF DESCRIPTION OF THE DRAWINGS

A first slot 11 is provided on one side of the fixed rod 5. One end of the top rod 10 extending to the inside of the fixed rod 5 penetrates the inside of the first slot 11. Second T-shaped slots 12 are provided on both sides of the inner cavity of the first slot 11. A movable plate 13 is provided in the inner cavity of the second T-shaped slot 12. The surface of the movable plate 13 contacts the inner cavity of the second T-shaped slot 12. A transverse plate 14 is fixedly connected to the surface of the movable plate 13. The surface of the transverse plate 14 An anti-skid plate 15 is fixedly connected, and second T-shaped sliders 16 are fixedly connected on both sides of the movable plate 13. The surface of the second T-shaped slider 16 is slidably connected to the inner cavity of the second T-shaped slide groove 12. A second spring 17 is fixedly connected to the inner side of the movable plate 13, and one end of the second spring 17 is fixedly connected to the inner wall of the first empty groove 11. The anti-skid plate 15 is made of rubber material to prevent sliding. A docking plate 22 is fixedly connected to the movable plate 13, and a docking hole 23 compatible with the top rod 10 is opened on the surface of the docking plate 22.

[0037] The electronic component fixing foot in this embodiment is suitable for openings of normal size or smaller than normal size. The second spring 17 is initially contracted, so the push rod 10 will only contact the moving plate 13 when the four sets of fixing rods 5 are contracted to a very small diameter. At this time, the diameter of the four sets of fixing rods 5 is small, and the elastic force of the first spring 8 is not enough to provide stability, so the push rod 10 is required to push out the moving plate 13 for reinforcement. When the four sets of fixing rods 5 are contracted to a very small diameter, the push rod 10 contacts the moving plate 13 and pushes the moving plate 13 outward. At this time, the moving plate 13 drives the anti-slip plate 15 to move, providing a The outward force reinforces the fixed foot to make its fixation more stable. When the electronic component is to be fixed, the fixing rod 5 is first inserted into the opening through the triangular plate 25. When the opening is smaller than the original fixed foot specification, the four groups of fixing rods 5 are affected by the opening and shrink inward at the same time. At this time, the fixing rod 5 squeezes the first spring 8 and reduces the diameter until it can be fixed through the opening. When the fixing rod 5 shrinks, it drives the moving plate 13 to move. When the moving plate 13 contacts the top rod 10, the moving plate 13 is resisted by the top rod 10 and no longer moves inward. At this time, the moving plate 13 and the anti-slip plate 15 together play a role of reinforcement and stability.

[0038] See also Figure 3 and Fig. 9 As shown, a second slot 18 is provided on the surface of the fixing rod 5, a torsion spring 19 is fixedly connected to the inner cavity of the second slot 18, a barb plate 20 is rotatably connected to the inner cavity of the second slot 18 and is located above the torsion spring 19, the inner side of the barb plate 20 is fixedly connected to one end of the torsion spring 19, and a spike cone 21 is fixedly connected to the barb plate 20.

[0039] When the electronic component needs to be fixed, the barb plate 20 is pressed down to allow the fixing rod 5 to pass through the opening, and then the barb plate 20 is released. The barb plate 20 pops out under the elastic force of the torsion spring 19. At this time, the barb plate 20 and the spike cone 21 jointly play a limiting role to prevent the fixing rod 5 from sliding out, making the structure more stable.

[0040] Working principle: when the electronic component needs to be fixed, the barbed plate 20 is pressed to allow the fixing rod 5 to pass through the opening. When the opening is smaller than the original fixed foot specification, the four groups of fixing rods 5 are affected by the opening and shrink inward at the same time. At this time, the fixing rod 5 squeezes the first spring 8 and reduces the diameter until it can be fixed through the opening. When the fixing rod 5 shrinks, it drives the moving plate 13 to move. When the moving plate 13 contacts the push rod 10, the moving plate 13 is resisted by the push rod 10 and no longer moves inward. At this time, the moving plate 13 and the anti-slip plate 15 play a role of reinforcement and stability together. Then the barbed plate 20 is released, and the barbed plate 20 pops out under the elastic force of the torsion spring 19. At this time, the barbed plate 20 and the spike cone 21 play a role of limiting together.
