Description

Technical Field

[0001] The present invention relates to the technical field of capacitors, and particularly to an organic film capacitor provided with a protection structure. Background Art

[0002] A film capacitor uses metal foil as electrodes. After overlapping it with plastic films such as polyethylene terephthalate, polystyrene, or polycarbonate from both ends and winding it into a cylindrical structure, it is called a capacitor. Since the uses of capacitors are relatively extensive, requirements have also been put forward for the protection measures and use convenience of capacitors.

[0003] Publication No. CN 218384844 U discloses an organic film capacitor. The organic film capacitor component group is placed inside the protection component group. During transportation, external extrusion and bumps will only affect the outer shell and will not damage the internal organic film capacitor component group. When the organic film capacitor component group needs to be used, by pressing the adjustment block, the movement of the adjustment block drives the connecting plate, and the connecting plate then drives the organic film capacitor component group to move. When the connecting plate moves to the position of the clamping part, since the clamping part is made of soft polyurethane, it will be pressed down by the connecting plate and allow the connecting plate to pass through. When the connecting plate passes through the clamping part, the clamping part will reset without the oppression of the connecting plate, and the clamping part will clamp the connecting plate through the cooperation with the spring. At this time, the pins extend out of the outer shell through the through holes on the outer shell and can be freely connected to the external circuit. The design of this protection component group prevents the pins from being damaged during transportation by placing the organic film capacitor component group inside the outer shell, and when it needs to be used, it can also be quickly extended without affecting the working speed, ultimately reducing material waste and working costs. However, the following problems still exist in the actual use of this patent: Although this organic film capacitor protects the capacitor body by setting the outer shell, the outer shell occupies a certain space. When installing the capacitor body, due to the limited space of the circuit board, there is not enough space to install the capacitor body and the outer shell together on the circuit board, resulting in restrictions on the installation of the capacitor body. At the same time, the pins cannot be disassembled, so when the pins are damaged, they cannot be quickly replaced, thus affecting the normal use of the capacitor.

[0004] Therefore, an organic film capacitor provided with a protection structure is proposed to solve the problems mentioned above. Summary of the Invention

A number of locking blocks 116 are fixedly installed on one side of the first protection housing 101 and the second protection housing 102 away from the connection and fixing brackets 108. By using the feature of the snap-fitting connection between the positioning holes 106 and the positioning insertion rods 107, the rapid connection of the first protection housing 101 and the second protection housing 102 is realized. At the same time, by using the feature of the snap-fitting connection between the first hook 115 and the locking blocks 116, the fixing of the first protection housing 101 and the second protection housing 102 is realized. The protection of the capacitor body 201 and the pin body 218 is realized through the first protection housing 101 and the second protection housing 102, avoiding the deformation or fracture of the pin body 218 caused by external collision or extrusion, thereby causing material waste and increasing the working cost.

When the installation space of the circuit board is limited, the first protective housing 101 and the second protective housing 102 need to be disassembled. By pulling the unlocking sliding plate 110, the locking plug 111 slides inside the connecting fixed bracket 108. When the locking plug 111 is separated from the first rotating rod 114, under the action of the unlocking rotating seat 113, the first rotating rod 114 can be rotated. When the first hook 115 is separated from the locking block 116, the first protective housing 101 and the second protective housing 102 can be quickly disassembled. When the space of the circuit board is large enough, the first protective housing 101, the second protective housing 102 and the capacitor body 201 can be jointly installed on the circuit board. By pushing the second push plate 123, the capacitor body 201 slides inside the first protective housing 101 and the second protective housing 102. When the capacitor body 201 pushes the connecting push plate 121 and the meshing rack 120 to move, taking advantage of the meshing connection between the meshing rack 120 and the rotating gear 117, the rotation of the connecting rotating shaft 118 and the heat dissipation rotating plate 119 can be realized, and the heat dissipation rotating plate 119 can be unfolded to facilitate the heat dissipation of the capacitor body 201. At the same time, heat dissipation fins are arranged inside the first protective housing 101 and the second protective housing 102, which can absorb heat from the capacitor body 201 and transfer it to the outside of the first protective housing 101 and the second protective housing 102, further improving the heat dissipation effect of the capacitor body 201.

A locking wheel disk 132 is fixedly installed at the top of the second rotating rod 131. The locking wheel disk 132 is engaged with the second push plate 123. When the second push plate 123 moves to one side of the locking wheel disk 132, it can drive the second rotating rod 131 and the fixed rotating disk 125 to rotate. By using the characteristic that the locking tooth 129 is engaged with the fixed gear disk 124, the locking wheel disk 132 can only rotate in one direction, so as to fix the second push plate 123. When it is necessary to move the capacitor body 201 into the first protective housing 101 and the second protective housing 102, by sliding the locking slider 127 to drive the connecting spring 128 and the locking tooth 129 to rotate, the rotation of the fixed rotating disk 125 can be realized. By using the spring at the end of the meshing rack 120, the reset of the connecting rotating shaft 118 and the heat dissipation rotating plate 119 can be realized, so that the heat dissipation rotating plates 119 are connected end to end, and the ventilation and heat dissipation window 105 can be closed. By the characteristic that the fixed thread sleeve 104 is threadedly connected to the through hole 103, the through hole 103 can be closed, which is convenient for protecting the capacitor body 201.

A pin body 218 is fixedly installed on the front face of the wiring terminal 216. By rotating the clamping threaded sleeve 215, due to the threaded connection between the clamping threaded sleeve 215 and the connection terminal 202, the clamping threaded sleeve 215 can be moved on the outside of the connection terminal 202. By the clamping threaded sleeve 215 pressing the third rotating rod 211, the third rotating rod 211 and the connection rotating shaft 206 rotate around the connection turntable 205. At the same time, the connection rotating shaft 206 drives the clamping rotating arm 213 to rotate. Due to the snap-fitting connection between the second hook 214 and the connection groove 217, the installation and fixation of the wiring terminal 216 and the pin body 218 can be realized. When the pin body 218 is damaged, by rotating the clamping threaded sleeve 215 in the reverse direction, when the clamping threaded sleeve 215 is separated from the third rotating rod 211, under the elastic force of the clamping spring 212, the second hook 214 is separated from the connection groove 217, and the wiring terminal 216 and the pin body 218 can be quickly installed and disassembled, facilitating the quick replacement of the pin body 218.

[0023] Working principle: Before using the organic thin film capacitor with a protection structure, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, by utilizing the feature of the snap connection between the positioning hole 106 and the positioning insertion rod 107, the rapid connection of the first protective housing 101 and the second protective housing 102 is achieved. At the same time, by utilizing the feature of the snap connection between the first hook 115 and the locking block 116, the fixation of the first protective housing 101 and the second protective housing 102 is realized. The protection of the capacitor body 201 and the pin body 218 is achieved through the first protective housing 101 and the second protective housing 102, avoiding the phenomenon that the pin body 218 is deformed or broken due to external collision or extrusion, thus causing material waste and an increase in working costs. When the installation space of the circuit board is limited, it is necessary to disassemble the first protective housing 101 and the second protective housing 102. By pulling the unlocking sliding plate 110 to drive the locking insertion rod 111 to slide inside the connection fixing bracket 108, when the locking insertion rod 111 is separated from the first rotating rod 114, under the action of the unlocking rotating seat 113, the first rotating rod 114 can be rotated. When the first hook 115 is separated from the locking block 116, the rapid disassembly of the first protective housing 101 and the second protective housing 102 can be realized.

[0024] Secondly, when the space of the circuit board is large enough, the first protective housing 101, the second protective housing 102 and the capacitor body 201 can be jointly installed on the circuit board. By pushing the second push plate 123, the capacitor body 201 can be driven to slide inside the first protective housing 101 and the second protective housing 102. When the capacitor body 201 pushes the connecting push plate 121 and the meshing rack 120 to move, by using the meshing connection feature between the meshing rack 120 and the rotating gear 117, the rotation of the connecting rotating shaft 118 and the heat dissipation rotating plate 119 can be realized, and the heat dissipation rotating plate 119 can be unfolded to facilitate the heat dissipation of the capacitor body 201. At the same time, heat dissipation fins are provided inside the first protective housing 101 and the second protective housing 102, which can absorb heat from the capacitor body 201 and transfer it to the outside of the first protective housing 101 and the second protective housing 102, further improving the heat dissipation effect of the capacitor body 201. When the second push plate 123 moves to one side of the locking wheel disc 132, it can drive the second rotating rod 131 and the fixed rotating disc 125 to rotate. By using the feature that the locking tooth 129 is engaged with the fixed tooth disc 124, the locking wheel disc 132 can only rotate in one direction, thereby fixing the second push plate 123. When it is necessary to move the capacitor body 201 into the first protective housing 101 and the second protective housing 102, by sliding the locking slider 127 to drive the connecting spring 128 and the locking tooth 129 to rotate, the rotation of the fixed rotating disc 125 can be realized. By using the spring at the end of the meshing rack 120, the reset of the connecting rotating shaft 118 and the heat dissipation rotating plate 119 can be realized, so that the heat dissipation rotating plates 119 are connected end to end, and the ventilation and heat dissipation window 105 can be closed. By using the feature that the fixed threaded sleeve 104 is threadedly connected to the through hole 103, the through hole 103 can be closed to facilitate the protection of the capacitor body 201.

[0025] Finally, by rotating the clamping threaded sleeve 215, by using the feature that the clamping threaded sleeve 215 is threadedly connected to the connecting terminal 202, the clamping threaded sleeve 215 can be driven to move outside the connecting terminal 202. By the clamping threaded sleeve 215 squeezing the third rotating rod 211, the third rotating rod 211 and the connecting rotating shaft 206 can rotate around the connecting turntable 205. At the same time, the connecting rotating shaft 206 drives the clamping rotating arm 213 to rotate. By using the feature that the second hook 214 is engaged with the connecting groove 217, the installation and fixation of the wiring terminal 216 and the pin body 218 can be realized.
