Note that the side of the sealing plate 126 is provided with a groove.

Further, one end of the sliding column 123 inserted into the sliding cylinder 122 is designed to be polygonal, and it can be understood that the polygonal sliding column 123 can only slide axially in the sliding cylinder 122 and cannot rotate.

It will be appreciated that when the nut 125 is turned, the spool 123 will be caused to displace axially within the spool 122, which in turn causes the first spring 124 to change resiliency.

Furthermore, a positioning rod 131 is fixedly connected to the positioning plate 130, the positioning rod 131 is symmetrically arranged, and the positioning rod 131 is slidably inserted into the second through hole 116 and the limiting groove 117.

Therefore, when the capacitor with the mounting structure is mounted, firstly, the thin film capacitor 1 is inserted into the frame 110, the pins 13 of the thin film capacitor 1 are inserted into the connecting sleeve 142, because the connecting sleeve 142, the slideway 141 and the fixing pins 143 are all made of conductive materials, the thin film capacitor 1 can be normally powered on for use, the positioning plate 130 is pulled, then the sealing head assembly 120 is inserted into the frame 110, the positioning plate 130 is loosened, the positioning block 132 is slidably inserted into the groove on the side surface of the sealing plate 126, the positioning plate 130 is continuously fixed to the sealing plate 126 through the tensile force of the tension spring 133, then the nut 125 is rotated, because one end of the sliding column 123 inserted into the sliding cylinder 122 is in a polygonal design, it can be understood that the polygonal sliding column 123 only axially slides but cannot rotate in the sliding cylinder 122, then when the nut 125 is rotated, the sliding column 123 axially displaces in the sliding cylinder 122, then the first spring 124 elastically changes, the resisting plate 121 has certain elasticity when the thin film capacitor 1 is abutted against the thin film capacitor 1, so that the thin film capacitor 1 is fixed in the frame 110 while the capacitor is fixedly mounted, and the thin film capacitor 1 can be conveniently mounted on the thin film capacitor, and the thin film capacitor to be mounted, and the capacitor to be conveniently mounted, and the capacitor to be mounted on the thin film capacitor to be mounted.

According to some embodiments of the present application, as shown in fig. 8-10, a parallel mechanism 200 is disposed on the frame 110, the parallel mechanism 200 is symmetrically disposed, the parallel mechanism 200 includes a guide bar 210, a sliding block 220, and a connecting rod 230, the guide bar 210 is U-shaped, the guide bar 210 is embedded in the frame 110, a U-shaped bottom end of the guide bar 210 is fixedly sleeved on the connecting sleeve 142, the sliding block 220 is connected to the sliding groove 113 in a limiting manner, the connecting rod 230 is fixedly connected to the sliding block 220, and the connecting rod 230 is connected to the limiting passage 114 in a limiting manner.

Wherein, two side elevation of the guide bar 210 with U-shaped design are fixedly connected with guide rings 211, and the guide rings 211 are matched with the holes symmetrically arranged on the side elevation of the frame 110.

It should be noted that the guide bar 210 and the guide ring 211 are both made of a conductive material, and the slider 220 is made of an insulating material.

Specifically, the upper end surface of the slider 220 is provided with a sliding cavity 221, and the sliding cavity 221 is matched with the slide 141.

Furthermore, the bottom end of the sliding cavity 221 is communicated with a fixing hole 222, and the fixing hole 222 is matched with the fixing leg 143.

It should be noted that, the fixing leg 143 is in sliding fit with the sliding groove 113, that is, the fixing leg 143 drives the sliding rail 141 to synchronously displace through the sliding of the sliding block 220 in the sliding groove 113, so that the fixing leg 143 displaces at the bottom of the frame 110.

Further, the link 230 is sleeved with a second spring 231, one end of the second spring 231 abuts against the limit channel 114, and the other end of the second spring 231 abuts against one end of the link 230 far away from the slider 220.

It can be understood that when the sliding block 220 slides in the sliding slot 113, the connecting rod 230 will be driven to synchronously displace in the limiting channel 114, and then the second spring 231 will be pressed, and under the elastic action of the second spring 231, there will be a tendency that two symmetrical fixing feet 143 will approach each other, so that the fixing feet 143 can be relatively stably plugged onto the circuit board before the circuit board is soldered thereto.

Therefore, in the using process of the capacitor with the installation structure, the other installation mechanism 100 can be plugged on the guide ring 211 by enabling the fixing feet 143 on the other installation mechanism 100 to penetrate through the holes symmetrically arranged on the side vertical face of the frame 110, wherein the distance-variable design of the fixing feet 143 enables the two capacitors with the installation structure to be plugged together more conveniently, then the fixing feet 143 and the guide ring 211 are welded to enable the two installation mechanisms 100 to be connected in parallel, then the two film capacitors 1 are respectively plugged into the two frames 110 to enable the two film capacitors 1 to be connected in parallel, and similarly, the design can simultaneously connect the two frames 110 in parallel on two sides of one frame 110, the two frames 110 connected in parallel can be further connected in parallel according to the specific using condition, and the detachable design between the film capacitors 1 and the frames 110 enables the film capacitors 1 connected in parallel to be more convenient to replace in the using process.

Among the correlation technique, this a condenser with mounting structure, in the use, in case because of electric current or voltage overload, will lead to the electric capacity overheated, the condition of "blasting" damage appears even, simultaneously in specific use, the electric capacity is overheated impaired but when the "blasting" condition does not appear, often need professional instrument to examine the electric capacity respectively, just can discern which specific electric capacity damages, and general staff can not discern easily, this is so that the maintenance process is comparatively specialized, and comparatively loaded down with trivial details.

Wherein, the part of the accommodating chamber 115 at the bottom side of the first heat conduction plate 310 is filled with oil.

It should be noted that, oil is an insulating substance, and even if leakage occurs, the oil does not have a large influence on a circuit, and then volume change of the oil after being heated is more obvious than that of a solid.

It should be further noted that, when the pin 13 on the film capacitor 1 is inserted into the connection sleeve 142, the elastic extrusion force of the seal plate 126 on the film capacitor 1 is adjusted by the rotation of the nut 125, so that the contact length between the pin 13 and the connection sleeve 142 is within a small range, and thus an open circuit is formed between the pin 13 and the connection sleeve 142 when the volume change drives the second heat conducting plate 320 and the film capacitor 1 to generate a small-amplitude displacement after the oil is heated, and the specific insertion range is determined according to the specific safe bearing range of the film capacitor 1.

It should be further noted that the sidewall of the frame 110 may be provided with detailed scales, so as to facilitate the control of the specific length of the pin 13 inserted into the connecting sleeve 142 during the process of installing the thin film capacitor 1, and facilitate the observation of the specific displacement of the thin film capacitor 1 after being heated on the frame 110, so as to facilitate manual identification.

Therefore, it can be understood that, in a specific using process, the film capacitor 1 firstly abuts against the second heat conduction plate 320, the pins 13 of the film capacitor pass through the second heat conduction plate 320 and then are inserted into the connection sleeve 142, after the sealing head assembly 120 fixes the film capacitor 1, the film capacitor 1 and the second heat conduction plate 320 are tightly attached together, and once the film capacitor 1 is overloaded with current or voltage in the using process, the temperature of the film capacitor 1 rises, in this process, the second heat conduction plate 320 absorbs heat and transmits the heat to the first heat conduction plate 310 through the connection posts 311, so that the oil contained in the containing cavity 115 is heated and expands, the first heat conduction plate 310 is forced to displace upwards, and then the film capacitor 1 is pushed upwards to press the sealing plate 126 through the second heat conduction plate 320, and the upward displacement of the film capacitor 1 will cause the pins 13 and the connection sleeve 142 to be separated to form an open circuit, and the film capacitor 1 can be prevented from being damaged by the overload current or voltage to some extent, and at the same time, because of the second heat conduction plate 320 and the film capacitor 1 are displaced, and the circuit board 1 is broken, and the circuit board is able to be detected by naked eyes during an inspection process, and the displacement of the film capacitor 1 can be detected.
