when the film capacitor 1 is used, the film capacitor 1 is inserted into the frame 110, the pins 13 penetrate through the first through holes 111 and are inserted into the connecting sleeves 142, then the end socket assembly 120 is fixed at the top of the frame 110 by utilizing the positioning plate 130 to match with the frame 110, so that the end socket assembly 120 is tightly propped against the film capacitor 1, the film capacitor 1 is prevented from loosening in the frame 110, the pins 13 and the connecting sleeves 142 are prevented from slipping, then the fixing pins 143 are inserted into positions, such as a circuit board, where the film capacitor 1 needs to be installed, and the fixing pins 143 and the installation positions are welded.
In addition, a capacitor with a mounting structure according to an embodiment of the present application has the following additional technical features:
it should be noted that, holes are symmetrically disposed on the side elevation of the frame 110.
The slide ways 141, the connecting sleeves 142 and the fixing pins 143 are made of conductive metal, so that a circuit series connection is formed between the pins 13 and the corresponding slide ways 141, connecting sleeves 142 and fixing pins 143.

Further, the end of the sliding post 123 inserted into the sliding barrel 122 is polygonal, and it is understood that the polygonal sliding post 123 can only slide axially in the sliding barrel 122 and cannot rotate.
It will be appreciated that when the nut 125 is turned, the spool 123 will be axially displaced within the spool 122, which in turn will cause the first spring 124 to change elastically.
Further, the positioning plate 130 is fixedly connected with positioning rods 131, the positioning rods 131 are symmetrically arranged, and the positioning rods 131 are slidably inserted into the second through holes 116 and the limiting grooves 117.
Specifically, a positioning block 132 is fixedly connected to one end of the positioning rod 131, which is far away from the positioning plate 130, and the positioning block 132 is adapted to the limiting groove 117, so as to prevent the positioning plate 130 from sliding out of the frame 110.
It should be noted that the positioning block 132 is matched with a groove formed on a side surface of the sealing plate 126.

Further, 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 slidably engaged with the sliding groove 113, that is, the sliding of the sliding block 220 in the sliding groove 113 drives the sliding way 141 to synchronously displace, so that the fixing leg 143 displaces at the bottom of the frame 110.
Further, the connecting rod 230 is sleeved with a second spring 231, one end of the second spring 231 is abutted against the limiting channel 114, and the other end of the second spring 231 is abutted against one end of the connecting rod 230 far away from the sliding block 220.

Therefore, in the use process of the capacitor with the mounting structure, the other mounting mechanism 100 can be plugged into the guide ring 211 by penetrating the fixing pins 143 on the other mounting mechanism through the holes symmetrically arranged on the side vertical surfaces of the frame 110, wherein the distance-variable design of the fixing pins 143 enables the two capacitors with the mounting structure to be more convenient when being plugged together, then the fixing pins 143 and the guide ring 211 are welded, the two mounting mechanisms 100 are connected in parallel, then the two film capacitors 1 are respectively plugged into the two frames 110, so that the two film capacitors 1 are connected in parallel, and in the same way, the two frames 110 can be simultaneously connected in parallel on two sides of one frame 110, and the two frames 110 connected in parallel can be further connected in parallel according to specific use conditions, and the detachable design between the film capacitors 1 and the frames 110 enables the plurality of film capacitors 1 connected in parallel to be more convenient to replace in the use process.
In the related art, in the use process, once the capacitor is overloaded due to current or voltage, the capacitor is overheated, even the situation of explosion damage occurs, and meanwhile, in the specific use process, when the capacitor is overheated and damaged but the situation of explosion does not occur, a professional tool is often needed to inspect the capacitor respectively, so that the capacitor is damaged, and a general worker cannot easily identify the capacitor, so that the overhaul process is specialized and complicated.
According to some embodiments of the present application, as shown in fig. 11, a protection mechanism 300 is disposed on the frame 110, the protection mechanism 300 includes a first heat-conducting plate 310 and a second heat-conducting plate 320, the first heat-conducting plate 310 and the accommodating cavity 115 are in a sealed sliding fit, a connecting post 311 is fixedly connected to the first heat-conducting plate 310, one end of the connecting post 311 away from the first heat-conducting plate 310 is fixedly connected to the second heat-conducting plate 320, and the second heat-conducting plate 320 is in sliding engagement with the frame 110.
Wherein the portion of the receiving chamber 115 at the bottom side of the first heat conductive plate 310 is filled with oil.
It should be noted that, firstly, oil is an insulating substance, even if leakage occurs, the oil will not have a great influence on the circuit, and secondly, the volume change of the oil after being heated is more obvious than that of solid.
It should be further noted that when the pin 13 on the thin film capacitor 1 is plugged into the connecting sleeve 142, the elastic extrusion force of the sealing plate 126 to the thin film capacitor 1 is adjusted by the rotation of the nut 125, so that the contact length between the pin 13 and the connecting sleeve 142 is within a small range, and when the second heat-conducting plate 320 and the thin film capacitor 1 are driven by the volume change to generate small displacement after the oil is heated, an open circuit is formed between the pin 13 and the connecting sleeve 142, and the specific plugging range depends on the safe bearing range of the specific thin film capacitor 1.
It should be further noted that, detailed scales may be provided on the side wall of the frame 110, so that the control pins 13 are conveniently inserted into the specific lengths of the connecting sleeves 142 during the process of installing the thin film capacitor 1, and meanwhile, the specific displacement of the thin film capacitor 1 after being heated on the frame 110 is conveniently observed, so that the thin film capacitor 1 is conveniently identified manually.
Therefore, it can be understood that, in a specific use process, the thin film capacitor 1 firstly collides against the second heat conducting plate 320, the upper pin 13 passes through the second heat conducting plate 320 and then is inserted into the connecting sleeve 142, after the end socket assembly 120 fixes the thin film capacitor 1, the thin film capacitor 1 and the second heat conducting plate 320 at this time are tightly attached together, and once the thin film capacitor 1 is overloaded with current or voltage in a use process, the temperature of the thin film capacitor 1 can rise, in this process, the second heat conducting plate 320 absorbs heat and transfers the heat to the first heat conducting plate 310 through the connecting post 311, so that the oil liquid contained in the containing cavity 115 is heated and expands, the first heat conducting plate 310 is forced to displace upwards, then the thin film capacitor 1 is pushed upwards by the second heat conducting plate 320 to squeeze the 126, and the upward displacement of the thin film capacitor 1 can lead the upper pin 13 and the connecting sleeve 142 to be separated, thus forming a break, and then the thin film capacitor 1 can avoid damage caused by current or voltage to a certain extent, meanwhile, the second heat conducting plate 320 and the thin film capacitor 1 can only recognize that the fault occurs in the thin film capacitor 1 according to the fault detection process.
