Description

Technical Field

[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a capacitor fixing device. Background Technology

[0002] Surface mount capacitors are widely used in consumer electronics, communication products, computers and peripherals, new energy, automation control, automotive industry, optoelectronic products, high-speed rail and aviation and military equipment, etc.

[0003] With the development of new energy vehicles, many surface mount capacitors have been applied to them. Given the complex usage scenarios and safety considerations of automobiles, the installation requirements for surface mount capacitors used in automobiles are relatively high. It is necessary to ensure that the surface mount capacitors can be stably installed and fixed, and will not shake due to the vibration of the vehicle during long-term use, so as to avoid poor contact or loosening of contacts caused by shaking, which could lead to circuit failure.

[0004] However, the surface mount capacitors currently used in new energy vehicles do not adequately consider the installation and fixing issues. They are simply soldered to the circuit board with the positive and negative terminals. During long-term use of the vehicle, the capacitor is prone to shaking due to the bumps and vibrations of the car. Over time, this shaking will eventually cause the positive and negative terminals to loosen or be damaged, thus affecting the lifespan of the capacitor product.

[0005] Therefore, it is necessary to conduct research and development on the existing technologies to provide a solution that allows capacitors to be stably and securely mounted on circuit boards to adapt to complex application environments with various bumps and vibrations.

[0033] Reference Figures 1-3 As shown in the figure, as an embodiment of the present invention, a capacitor fixing device 300 is provided for mounting and fixing a capacitor 100. The capacitor fixing device 300 includes: a base 30, a plurality of support blocks perpendicular to the inner surface of the base 30 at the periphery of the inner surface of the base 30, and a welding piece 31 mounted on the base 30; wherein, the inner sides of the plurality of support blocks enclose a receiving space 301 for receiving the capacitor; the welding piece 31 is mounted on the bottom surface of the base 30 for welding to a circuit board, thereby fixing the capacitor fixing device 300 to the circuit board, and thus stably mounting the capacitor 100 on the circuit board.

[0034] Reference Figure 3 , Figure 4 , Figure 6 As shown, the base 30 has a mounting hole 302 at one end near the bottom surface of the base for mounting the welding piece 31; the mounting hole 302 penetrates the inner surface and outer surface of the base 30, and after the welding piece 31 is mounted in the mounting hole 302, one side of the welding piece 31 is exposed on the inner surface of the base 30; one end of the capacitor cover plate is defined as the top end and the other end opposite the top end is defined as the bottom end, and the bottom end of the capacitor 100 is placed in the receiving space 301 of the capacitor fixing device 300, closely fitting the inner surface of the base 30 and contacting the welding piece 31.

[0035] Reference Figure 4 , Figure 5As shown, the welding piece 31 includes a mounting portion 310 and a welding portion 311 bent perpendicular to the mounting portion 310. In some embodiments, the mounting portion 310 is mounted at the mounting hole 302 of the base, and a retaining piece 3101 is provided at the end of the mounting portion 310, which is held in place by the retaining piece 3101 on the inner surface of the base. The welding portion 311 is attached to the bottom surface of the base and protrudes from the bottom surface of the base. In some embodiments, the welding portion 311 is fixedly connected to the bottom surface of the base, thereby making the capacitor fixing device more stable when mounted on the circuit board. It should be noted that in some embodiments, the welding piece 31 can also be fixed to the base 30 by adhesive application or other methods, such as by opening a mounting groove on the bottom surface of the base, and installing the welding portion of the welding piece in the mounting groove.

[0036] Refer to Figure 1 , Figures 3-5 As shown, the base 30 is also provided with a slot 32 that penetrates the inner surface and the outer surface of the base; the bottom surface of the base 30 is set as a flat plane for mounting and fixing the capacitor fixing device on the circuit board.

[0037] Reference Figure 1 As shown, the inner sides of the plurality of support blocks are provided with arc-shaped surfaces, so that the inner sides of the plurality of support blocks enclose a cylindrical cavity to fit a circular capacitor. It should be noted that in some other embodiments, the inner sides of the plurality of support blocks can also be provided with other shapes, such as being provided with planes, and the inner sides of multiple support blocks enclose a square cavity to fit a square capacitor.

[0038] Reference Figure 1 As shown, in one embodiment, the plurality of support blocks includes a first support block 33, a second support block 34, a third support block 35, and a fourth support block 36; wherein the first support block 33, the second support block 34, and the third support block 35 are located on one half of the base, and the fourth support block 36 is located on the other half of the base; slots 32 are respectively provided between the second support block 34 and the first support block 33 and the third support block 35. A groove 37 is provided between the first support block 33 and the fourth support block 36, and correspondingly, a groove 37 is also provided between the third support block 35 and the fourth support block 36; the groove 37 is higher than the inner surface of the base. (Refer to...) Figure 3 As shown, in some embodiments, the inner side of the fourth support block 36 is L-shaped at the position corresponding to the mounting hole 302 of the seat. With this design, the inner surface of the receiving space 301 for mounting the capacitor is not completely arc-shaped, thereby increasing the friction between the receiving space 301 and the surface of the capacitor and preventing the capacitor 100 from rotating. In addition, by hollowing out, the material can be reduced and the weight of the capacitor fixing device can be reduced.

[0039] Reference Figure 3 As shown, there are two mounting holes 302, which are respectively located at the two corners of the fourth support block 36 near the bottom surface of the base; corresponding to the mounting holes 302, there are two welding pieces 31, which are respectively installed at the two mounting holes.

[0040] Reference Figures 3-5 As shown, the slots 32 are symmetrically arranged around the centerline of the outer surface of the base, and the outer surface of the base also has channels 38 communicating with the slots 32. When installing and fixing the capacitor, the base 30 mainly bears the weight on the half where the fourth support block 36 is located. Therefore, this design balances the structural strength and overall weight of the capacitor fixing device. By setting slots and grooves, materials can be reduced and weight can be decreased without affecting the overall strength of the capacitor fixing device. At the same time, it can also increase the exposed area of ​​the capacitor, thereby improving the heat dissipation effect.

[0041] In some embodiments, the base 30 is further provided with a groove 39, which is configured to divide the capacitor fixing device into two halves; in some embodiments, the groove 39 connects the second support block 34, the outer surface of the base and the fourth support block 36.
