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 casing 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 casing through the through grooves on the outer casing 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 casing, 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:

[0004] Although the organic film capacitor protects the capacitor body by setting the outer casing, the outer casing 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 casing 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.

[0005] Therefore, an organic film capacitor provided with a protection structure is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The object of the present invention is to provide an organic thin-film capacitor with a protection structure, so as to solve the problems raised in the above background technology. Although the organic thin-film capacitor protects the capacitor body by setting an outer casing, the outer casing 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 casing together on the circuit board, resulting in limited installation of the capacitor body.

At the same time, by utilizing the characteristic of the snap-fitting connection between the first hook and the locking block, the fixation of the first protection housing and the second protection housing is realized. By squeezing the third rotating rod with the clamping threaded sleeve, the third rotating rod and the connecting rotating shaft rotate around the connecting turntable. At the same time, the connecting rotating shaft drives the clamping rotating arm to rotate. By utilizing the characteristic of the snap-fitting connection between the second hook and the connecting groove, the installation and fixation of the wiring terminal and the pin body can be realized. The specific content is as follows:

[0022] 1. By setting up a protection mechanism, not only can the quick connection of the first protection housing and the second protection housing be achieved by utilizing the feature of the positioning hole being snap-fitted with the positioning insertion rod, but also the fixation of the first protection housing and the second protection housing can be realized by using the feature of the snap-fitting connection between the first hook and the locking block. The protection of the capacitor body and the pin body is achieved through the first protection housing and the second protection housing, avoiding the deformation or fracture of the pin body caused by external collision or extrusion, which may result in material waste and an increase in working costs. When the installation space of the circuit board is limited, the first protection housing and the second protection housing need to be disassembled. By pulling the unlocking sliding plate to drive the locking insertion rod to slide inside the connecting and fixing bracket, when the locking insertion rod separates from the first rotating rod, under the action of the unlocking rotating seat, the first rotating rod can be rotated. When the first hook separates from the locking block, the quick disassembly of the first protection housing and the second protection housing can be achieved. When the space of the circuit board is large enough, the first protection housing, the second protection housing, and the capacitor body can be jointly installed on the circuit board. By pushing the second push plate to drive the capacitor body to slide inside the first protection housing and the second protection housing, when the capacitor body pushes the connecting push plate and the meshing rack to move, by using the feature of the meshing connection between the meshing rack and the rotating gear, the rotation of the connecting rotating shaft and the heat dissipation rotating plate can be realized, and the heat dissipation rotating plate can be unfolded to facilitate the heat dissipation of the capacitor body. At the same time, heat dissipation fins are provided inside the first protection housing and the second protection housing, which can absorb heat from the capacitor body and transfer it to the outside of the first protection housing and the second protection housing, further improving the heat dissipation effect of the capacitor body. When the second push plate moves to one side of the locking wheel disc, it can drive the second rotating rod and the fixed rotating disc to rotate. By using the feature of the snap-fitting connection between the locking teeth and the fixed tooth disc, the locking wheel disc can only rotate in one direction, thereby fixing the second push plate. When it is necessary to move the capacitor body into the first protection housing and the second protection housing, by sliding the locking slider to drive the connecting spring and the locking teeth to rotate, the rotation of the fixed rotating disc can be realized. By using the spring at the end of the meshing rack, the reset of the connecting rotating shaft and the heat dissipation rotating plate can be achieved, so that the heat dissipation rotating plates are connected end to end, and the ventilation and heat dissipation window can be closed. By using the feature of the fixed threaded sleeve being threadedly connected to the through hole, the through hole can be closed, facilitating the protection of the capacitor body;

[0023] 2. By setting up the pin connection mechanism, the clamping threaded sleeve can be rotated. Utilizing the characteristic of the threaded connection between the clamping threaded sleeve and the connection terminal, the clamping threaded sleeve can move on the outside of the connection terminal. By squeezing the third rotating rod with the clamping threaded sleeve, the third rotating rod and the connection rotating shaft can rotate around the connection turntable. At the same time, the connection rotating shaft drives the clamping rotating arm to rotate. Utilizing the characteristic of the engagement connection between the second hook and the connection slot, the installation and fixation of the wiring terminal and the pin body can be achieved. When the pin body is damaged, by rotating the clamping threaded sleeve in the reverse direction, when the clamping threaded sleeve is separated from the third rotating rod, under the elastic force of the clamping spring, the second hook is separated from the connection slot, enabling the rapid installation and disassembly of the wiring terminal and the pin body, facilitating the rapid replacement of the pin body.

Through holes 103 are formed on the front surfaces of both the first protection shell 101 and the second protection shell 102. The fixed thread sleeve 104 is threadedly connected to the first protection shell 101 and the second protection shell 102 through the through holes 103. Among them, ventilation and heat dissipation windows 105 are formed on one side inside both the first protection shell 101 and the second protection shell 102. Positioning holes 106 are symmetrically formed on the sides of both the first protection shell 101 and the second protection shell 102. Among them, positioning insertion rods 107 are symmetrically installed on one side of the first protection shell 101 and the second protection shell 102 away from the positioning holes 106.

Unlocking springs 109 are symmetrically installed on one side of the connection and fixing brackets 108 up and down. The ends of the two unlocking springs 109 are fixedly connected to an unlocking sliding plate 110. A locking insertion rod 111 is fixedly connected to one side of the unlocking sliding plate 110 close to the unlocking spring 109. A locking inclined groove 112 is formed at the end of the locking insertion rod 111. Unlocking rotating seats 113 are fixedly installed on one side of the first protection shell 101 and the second protection shell 102 close to the connection and fixing brackets 108. A first rotating rod 114 is rotatably connected inside the unlocking rotating seats 113. A first hook 115 is fixedly installed at the end of the first rotating rod 114. A number of locking blocks 116 are fixedly installed on one side of the first protection shell 101 and the second protection shell 102 away from the connection and fixing brackets 108. By using the feature of the engagement between the positioning holes 106 and the positioning insertion rods 107, the rapid connection of the first protection shell 101 and the second protection shell 102 is realized. At the same time, by using the feature of the engagement between the first hook 115 and the locking blocks 116, the fixation of the first protection shell 101 and the second protection shell 102 is realized. The protection of the capacitor body 201 and the pin body 218 is achieved through the first protection shell 101 and the second protection shell 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.

[0038] The locking block 116 is engaged and connected with the first hook 115. A plurality of rotating gears 117 are rotatably connected to the top and bottom of the ventilation and heat dissipation window 105. A connecting rotating shaft 118 is fixedly connected between the upper and lower rotating gears 117. A heat dissipation rotating plate 119 is fixedly installed on one side of the connecting rotating shaft 118. One side of the upper and lower rotating gears 117 is engaged with a meshing rack 120 respectively. A connecting push plate 121 is fixedly connected between the upper and lower meshing racks 120. 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, 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, by utilizing 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.

[0039] A pushing chute 122 is provided on the inner side of the top of both the first protective housing 101 and the second protective housing 102.

A limiting stop 130 is fixedly installed at the end of the fixed gear disk 124 close to the locking tooth 129. The locking tooth 129 is engaged with the fixed gear disk 124. A second rotating rod 131 is fixedly connected to the center position of the top of the fixed rotating disk 125. 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 pushing plate 123. When the second pushing 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, thereby fixing the second pushing 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 is 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 threaded 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.

[0040] The pin connection mechanism 2 includes a capacitor body 201. Connection terminals 202 are symmetrically installed on the front surface of the capacitor body 201. Connection holes 203 are formed on the front surfaces of the connection terminals 202. Second fixing brackets 204 are fixedly installed around the inside of the connection terminals 202.

A second hook 214 is fixedly installed at the end of the clamping rotating arm 213. A clamping threaded sleeve 215 is threadedly connected to the outside of the connection terminal 202. A wiring terminal 216 is snap-fitted to the connection hole 203. Connection grooves 217 are formed around the outside of the wiring terminal 216. A pin body 218 is fixedly installed on the front surface of the wiring terminal 216. By rotating the clamping threaded sleeve 215 and using the feature that the clamping threaded sleeve 215 is threadedly connected to 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 squeezing 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. By using the feature that the second hook 214 is snap-fitted to the connection groove 217, the installation and fixation of the wiring terminal 216 and the pin body 218 can be achieved. When the pin body 218 is damaged, by reversely rotating the clamping threaded sleeve 215, 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.

[0041] Working principle: Before using the organic thin film capacitor with a protection structure, it is necessary to first check the overall condition of the device to determine that it can work properly. According to Figure 1 - Figure 11As shown in the figure, first, by using 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 realized. At the same time, by using 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 deformation or fracture of the pin body 218 caused by external collision or extrusion, thus resulting in material waste and increased 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, the locking insertion rod 111 is driven 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.

[0042] 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 connection push plate 121 and the meshing rack 120 to move, by using 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. 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 engagement connection between the locking teeth 129 and 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 teeth 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 threaded connection between the fixed threaded sleeve 104 and the through hole 103, the through hole 103 can be closed to facilitate the protection of the capacitor body 201.

[0043] Finally, by rotating the clamping threaded sleeve 215, by using the threaded connection between the clamping threaded sleeve 215 and the connection terminal 202, the clamping threaded sleeve 215 can be driven to move outside the connection 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 engagement 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 reversely rotating the clamping threaded sleeve 215, 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.
