Description

Technical Field

[0001] The invention relates to the technical field of electronic component insulation fixing, and in particular to an electronic component insulation fixing device. Background Art

[0002] Electronic components are components of electronic elements and small machines and instruments. They are often composed of several parts and can be used in similar products. They often refer to certain parts in industries such as electrical appliances, radios, and instruments. They are a general term for electronic devices such as capacitors, transistors, hairsprings, and springs. In complex electronic equipment, various electronic components need to be precisely fixed on circuit boards or other structures inside the equipment to ensure that they can work properly and connect with each other.

[0003] Most of the current electronic components are soldered on the circuit board using pins, such as capacitors. However, the pins of capacitors are thin, the support stability is poor, and they are easy to break, so that the electronic components are easy to fall off the circuit board, affecting normal operation. In order to avoid these situations, most of them use insulating fixing devices to provide stable support and insulation isolation for electronic components to prevent short circuits or electrical interference between components. However, most of the existing insulating fixing devices can only fix and support the electronic components after welding is completed, and cannot position the electronic components when they are welded. Therefore, during welding, it is necessary to constantly adjust the verticality of the electronic components and pins, which can easily cause the electronic components and pins to be skewed. The pins will break after a long time, affecting the fixing effect; secondly, when fixing, most of them use clamping plates to fix and support the outer wall of the electronic components. The contact area between the clamping plate and the electronic components is large, which will reduce the contact area between the electronic components and the air, indirectly reduce the heat dissipation area of ​​the electronic components, and affect the ventilation and heat dissipation effect. Therefore, we propose an insulating fixing device for electronic components. Summary of the invention

[0004] In order to solve the problem that most existing insulating fixing devices can only fix and support electronic components after welding is completed, but cannot position the electronic components when welding, so that the verticality of the electronic components and pins needs to be constantly adjusted during welding, which easily causes the electronic components and pins to be skewed, and the pins to break after a long time, affecting the fixing effect; the purpose of the present invention is to provide an insulating fixing device for electronic components.

[0043] Working principle: When the capacitor pins are welded on the circuit board 1, the positioning mechanism 2 of the fixing device of the present invention is used to position them, and then the fixing mechanism 3 is used to firmly support them, and then welding is performed to ensure the verticality of the electronic components and pins. Because the top is heavy and the feet are light, the electronic components need to be supported;

[0044] First, the staff places the electronic components on the outside of the mounting ring 308 and the mounting plate 302, and uses the adjustable bracket 4 to support the mounting plate 302. Then the staff rotates the handle 214 to drive the third rotating shaft 215 and the first active bevel gear 203 to rotate, the first active bevel gear 203 drives the first bevel gear 200 to rotate, the first bevel gear 200 drives the first rotating shaft 201 to rotate, the first rotating shaft 201 drives the driving pulley 204 to rotate, the driving pulley 204 drives the driven pulley 205 and the driven pulley 206 to rotate, the driven pulley 206 drives the second rotating shaft 207 to rotate, and the second rotating shaft 207 drives the disc 208 to rotate. The disc 208 drives the three groups of connecting rods 209 to make circular motion, the connecting rods 209 drive the positioning plate 210 and the positioning rod 211 to move, the positioning rod 211 moves close to each other in the guide groove 213, and the positioning rod 212 can position the outer wall of the electronic component. At this time, the electronic component and the pin are in a vertical state. After the positioning is completed, the staff rotates the rotating plate 316 to drive the second active bevel gear 314 to rotate, the second active bevel gear 314 drives the second bevel gear 300 to rotate, the second bevel gear 300 drives the fifth shaft 312 and the second gear 313 to rotate, the second gear 313 drives the teeth 303 to rotate, and the teeth 303 drives the rotating frame 304 to rotate. The rotating frame 304 drives the rack 305 to rotate, the rack 305 drives the first gear 301 and the fourth rotating shaft 306 to rotate, the fourth rotating shaft 306 drives the slide bar 307 to rotate, the slide bar 307 moves in the fixed sleeve 310, and the fixed sleeve 310 rotates at the same time, so that the slide bar 307 drives the fixed wheel 311 to rotate and clamp the outer wall of the capacitor, so as to fix and support the capacitor, and use the locking bolt 317 to lock and fix the rotating plate 316, and use the screw to fix the adjustable bracket 4 on the circuit board 1, and then weld the pins. After welding, the staff loosens the fixing bolt 13, and then pulls the vertical plate 216 upward to insert the plug 1 1 is pulled out from the slot 12, so that the positioning mechanism 2 can be removed, the volume of the overall fixing mechanism 3 is reduced, and the fixing mechanism 3 is left to firmly support the electronic components. With the cooperation of the inclined ventilation slot 5, ventilation can be carried out to improve the ventilation effect of the capacitor. At the same time, the contact area between the fixing wheel 311 and the capacitor is small, which can ensure the ventilation effect of the capacitor. The thermal conductive insulating layer 7 can prevent the current from flowing between components with different potentials to avoid the occurrence of short circuit accidents. At the same time, the heat generated by the capacitor can be conducted. The capacitor can be dissipated under the action of the heat dissipation ring 8. At the same time, the first heat dissipation hole 9 and the second heat dissipation hole 10 can improve the heat dissipation effect.

[0045] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
