Description

Technical Field

[0001] The present invention belongs to the technical field of capacitors, and particularly relates to a ring-break type pin protection compensation capacitor. Background Art

[0002] A capacitor is an electronic component used for storing electrical energy, having the ability to store electric charges. It usually consists of two conductors and a dielectric. When a voltage is applied to the two conductors of the capacitor, the capacitor accumulates charges and stores electrical energy. The basic function of the capacitor is to store and release electrical energy, and it is used in a circuit to regulate current, filter, smooth voltage, etc. A capacitor pin is a metal conductor used to connect the electrodes of the capacitor and an external circuit. The structure and material of the capacitor pin can be selected according to different application scenarios and requirements.

[0003] In the prior art, there is a ring-break type pin protection compensation capacitor with the patent publication number CN205303180U. The above patent includes a capacitor housing, in which a capacitor element is arranged. The capacitor element is wrapped with insulating paper, and there is insulating paraffin between the insulating paper and the housing. The capacitor element is connected to a conductive copper sheet below the pin plate through a wire. The conductive copper sheet is fixed on the pin plate by an open rivet. An electrode pin is vertically inserted into the up-turned opening of the open rivet. The bottom end of the electrode pin is welded and fixed to the opening at the bottom end of the open rivet. A ring-shaped groove notch is formed around the middle of the electrode pin... This device changes the force-bearing structure of the electrode pin. When the capacitor is damaged and expands, the electrode pin is broken at the groove, realizing a compensation capacitor structure with rapid open circuit after the component is damaged and improving the safety of the overall circuit. However, there are still the following deficiencies in actual use: In reality, although this device has a ring-shaped groove notch, the strength of such a capacitor pin is relatively low and cannot fully withstand the mechanical stress during operation. It is prone to bending or breaking itself, and cannot ensure the stability and reliability of the capacitor operation.

[0004] Therefore, there is a need for a ring-break type pin protection compensation capacitor to solve the problem of relatively low strength of the existing ring-break type pins in the prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide a ring-break type pin protection compensation capacitor to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A ring-breaking type pin-protecting compensating capacitor, comprising a capacitor body, two pin bases are fixedly connected to the top of the capacitor body, guide pins are threadedly connected to the tops of the two pin bases, annular groove notches are provided on the surfaces of the two guide pins, first mounting plates are fixedly connected to both sides of the capacitor body, connecting columns are fixedly connected to the tops of the two first mounting plates, clamping balls are fixedly connected to the tops of the two connecting columns, a protective cover is arranged on the top of the capacitor body, two clamping mechanisms corresponding to the clamping balls are arranged at the bottom of the protective cover, and a stabilizing mechanism is arranged inside the protective cover.

[0007] It should be noted in the solution that an anti-corrosion layer is coated on the outer wall of the capacitor body.

[0008] Furthermore, it is worth noting that the clamping mechanism includes a second mounting plate fixedly connected to the bottom of the protective cover, a rotating seat is fixedly connected to the bottom of the second mounting plate, two clamping arc plates are rotatably mounted at the bottom of the rotating seat, first springs are fixedly connected to the positions near the front and rear ends of the bottom of the second mounting plate, and baffles are fixedly connected to the bottoms of the two first springs.

[0009] Even further, it should be noted that the outer wall of the clamping ball is in close fit with the inner walls of the two clamping arc plates.

[0010] As a preferred implementation manner, the inner ends of the two baffles are respectively fixedly connected to the bottom positions of the outer ends of the corresponding clamping arc plates.

[0011] As a preferred implementation manner, the stabilizing mechanism includes two through holes opened on the top of the protective cover, support plates are fixedly connected to the positions near the outer sides of the inner walls of the two through holes, first arc plates are fixedly connected to the inner sides of the two support plates, two sliding rods are slidably connected to both sides of the top of the protective cover, pressing plates are fixedly connected to the outer sides of each two corresponding sliding rods, fixing blocks are fixedly connected to the inner sides of the multiple sliding rods, second arc plates are fixedly connected between each two corresponding fixing blocks, and a second spring is fixedly connected between the two second arc plates.

[0012] As a preferred implementation manner, anti-slip teeth are provided on the outer sides of the two pressing plates.

[0013] As a preferred implementation manner, protective pads are fixedly connected to the inner sides of the two first arc plates and the inner sides of the two second arc plates.

[0014] Compared with the prior art, the ring-breaking type pin-protecting compensating capacitor provided by the present invention has at least the following beneficial effects:

[0015] (1) By setting up a stabilizing mechanism, under the action of the second spring, the two second arc-shaped plates move inward and cooperate with the two first arc-shaped plates to clamp and stabilize the guide pin. This can effectively reduce the influence of mechanical stress on the guide pin, thereby enhancing the stability and reliability of the guide pin, preventing deformation and fracture of the guide pin. The stabilizing mechanism ensures the stability of the capacitor body in the external environment or during operation, reduces the risk of failures caused by damage to the guide pin, and thus improves the safety of the capacitor body.

[0016] (2) By setting up a clamping mechanism, the protective cover is detachably connected to the top of the capacitor body, making it more convenient when the capacitor body needs to be inspected, maintained, or replaced. Users can quickly operate without additional tools, greatly improving the efficiency of repair and operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further describes the present invention with reference to the embodiments.

[0024] Please refer to Figures 1-5, the present invention provides an annular-break type pin-protected compensating capacitor, which includes a capacitor body 1. Two pin seats 2 are fixedly connected to the top of the capacitor body 1. Guide pins 3 are threadedly connected to the tops of the two pin seats 2. Annular groove notches 4 are formed on the surfaces of the two guide pins 3. First mounting plates 5 are fixedly connected to both sides of the capacitor body 1. Connecting columns 6 are fixedly connected to the tops of the two first mounting plates 5. Snap balls 7 are fixedly connected to the tops of the two connecting columns 6. A protective cover 8 is arranged on the top of the capacitor body 1. Two clamping mechanisms 9 corresponding to the snap balls 7 are arranged at the bottom of the protective cover 8. A stabilizing mechanism 10 is arranged inside the protective cover 8.

[0025] Further, as Figure 1 and Figure 2 shown, it is specifically worth noting that an anti-corrosion layer is coated on the outer wall of the capacitor body 1. The anti-corrosion layer can effectively prevent moisture, salts and other corrosive substances in the air from contacting the surface of the capacitor body 1, thereby reducing oxidation and corrosion phenomena and prolonging the service life of the capacitor body 1.

[0026] Further, as Figure 4 shown, it is specifically worth noting that the clamping mechanism 9 includes a second mounting plate 901 fixedly connected to the bottom of the protective cover 8. A rotating seat 902 is fixedly connected to the bottom of the second mounting plate 901. Two clamping arc plates 903 are rotatably installed at the bottom of the rotating seat 902. First springs 904 are fixedly connected to both the front and rear end positions near the bottom of the second mounting plate 901. Baffles 905 are fixedly connected to the bottoms of the two first springs 904. By setting the clamping mechanism 9, the protective cover 8 is detachably connected to the top of the capacitor body 1, making it more convenient when the capacitor body 1 needs to be inspected, maintained or replaced. Users can quickly operate without additional tools, greatly improving the efficiency of maintenance and operation.

[0027] Further, as Figure 4 shown, it is specifically worth noting that the outer wall of the snap ball 7 is in close fit with the inner walls of the two clamping arc plates 903. The close fit between the snap ball 7 and the clamping arc plates 903 can ensure a more stable connection of the capacitor assembly during installation and use, effectively preventing loosening or detachment of the connection due to vibration, external force or improper operation.

[0028] Further, as Figure 4 shown, it is specifically worth noting that the inner ends of the two baffles 905 are respectively fixedly connected to the bottom positions of the outer ends of the corresponding clamping arc plates 903, ensuring that the two first springs 904 exert a thrust on the two baffles 905, thereby transmitting the thrust to the two clamping arc plates 903, causing the two clamping arc plates 903 to reset and clamp and fix the snap ball 7.

[0029] According to the above working process, it can be seen that by setting the clamping mechanism 9, the protective cover 8 is detachably connected to the top of the capacitor body 1, making it more convenient when the capacitor body 1 needs to be inspected, maintained or replaced. Users can quickly operate without additional tools, greatly improving the efficiency of maintenance and operation.

[0030] Furthermore, as Figure 5 shown, it is worth specifically stating that the stabilizing mechanism 10 includes two through holes 1001 opened on the top of the protective cover 8. On the inner wall of each of the two through holes 1001 near the outer side, a support plate 1002 is fixedly connected. On the inner side of each of the two support plates 1002, a first arc plate 1003 is fixedly connected. On both sides of the top of the protective cover 8, two sliding rods 1004 are slidably connected. On the outer side of each pair of corresponding sliding rods 1004, a pressing plate 1005 is fixedly connected. On the inner side of each of the multiple sliding rods 1004, a fixing block 1006 is fixedly connected. Between each pair of corresponding fixing blocks 1006, a second arc plate 1007 is fixedly connected. A second spring 1008 is fixedly connected between the two second arc plates 1007. By setting the stabilizing mechanism 10 to clamp and stabilize the guide pin 3, it can effectively reduce the influence of mechanical stress on the guide pin 3, thereby enhancing the stability and reliability of the guide pin 3, preventing the deformation and fracture of the guide pin 3. The stabilizing mechanism 10 ensures the stability of the capacitor body 1 in the external environment or during the operation process, reduces the risk of failure caused by the damage of the guide pin 3, and thus improves the safety of the capacitor body 1.

[0031] Furthermore, as Figure 5 shown, it is worth specifically stating that anti-slip teeth are provided on the outer side of each of the two pressing plates 1005. The anti-slip teeth can effectively increase the friction between the pressing plate 1005 and the hand, thereby preventing slipping during the operation process.

[0032] Furthermore, as Figure 5 shown, it is worth specifically stating that protective pads are fixedly connected to the inner sides of the two first arc plates 1003 and the inner sides of the two second arc plates 1007. The protective pads can effectively reduce the direct contact between the guide pin 3 and the arc plates, avoid damage to the surface of the guide pin 3 caused by friction or impact, and extend the service life of the capacitor body 1.

[0033] This solution has the following working process: In actual use, install the two guide pins 3 on the tops of the two pin sockets 2. Press the two pressing plates 1005 inward to pass the two guide pins 3 through the through holes 1001. Press the protective cover 8 downward to engage the clamping balls 7 on the inner walls of the two clamping arc plates 903. The two first springs 904 exert a thrust on the two clamping arc plates 903, causing the two clamping arc plates 903 to reset and clamp and fix the clamping balls 7, thus completing the installation of the protective cover 8. At this time, release the two pressing plates 1005. Under the action of the second spring 1008, the two second arc-shaped plates 1007 move inward and cooperate with the two first arc-shaped plates 1003 to clamp and stabilize the guide pins 3.

[0034] In summary: By setting the clamping mechanism 9, the protective cover 8 is detachably connected to the top of the capacitor body 1, making it more convenient when the capacitor body 1 needs to be inspected, maintained or replaced. Users can quickly operate without additional tools, greatly improving the efficiency of maintenance and operation. By setting the stabilizing mechanism 10 to clamp and stabilize the guide pins 3, it can effectively reduce the influence of mechanical stress on the guide pins 3, thereby enhancing the stability and reliability of the guide pins 3, preventing deformation and fracture of the guide pins 3. The stabilizing mechanism 10 ensures the stability of the capacitor body 1 in the external environment or during the operation process, reducing the risk of failures caused by damage to the guide pins 3, thus enhancing the safety of the capacitor body 1.
