Abstract

[0002] Capacitors are widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, etc. The existing composite capacitors have weak surface compressive strength, so they are prone to deformation or cracking when impacted by external forces, causing the capacitors to be damaged and unable to be used. The traditional one-piece protective housing is connected to the capacitor sleeve and lacks the necessary anti-collision buffer, so once the composite capacitor is hit, it is very easy to be destroyed. In order to extend the service life of the composite capacitor, we propose a composite structure capacitor. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] In this embodiment, refer to Figure 1-4A composite structure capacitor includes a shell 1 and a capacitor body 3. The shell 1 has an installation cavity 2 for accommodating the capacitor body 3 formed inwardly from its bottom surface. An integrally formed protective top plate 5 is provided on the top of the shell 1. A protective bottom plate 6 is threadedly connected to the bottom of the shell 1. A through hole is provided on the protective top plate 5 for the top pin 4 of the capacitor body 3 to pass through.
[0022] After the capacitor body 3 is installed in the housing 1, the protective bottom plate 6 is used to lock the threads, and thread glue can be applied to the threaded joints to ensure that the assembled product has a high degree of sealing, thereby effectively isolating the external environment and ensuring the normal use of the capacitor.
[0023] like Figure 1 or Figure 2 As shown, the housing 1 is a cylindrical structure, and the outer surface of the housing 1 is provided with a plurality of circumferentially distributed mounting grooves 13, in which the mounting grooves 13 are respectively embedded with buffer blocks 7, and the inner surfaces of the buffer blocks 7 are respectively installed in the respective mounting grooves 13 through connecting rods 8. Figure 2 And attached Figure 3 It can be seen that the inner wall of the mounting groove 13 is provided with a plurality of mounting holes 15 which are spaced apart in sequence, and a connecting rod 8 is rotatably installed in each mounting hole 15. The connecting rods 8 are kept parallel to each other and are all set to be tilted downward, and the other end of each connecting rod 8 is rotatably installed on the inner surface of the corresponding buffer block 7.
[0024] As attached Figure 4 As shown, the bottom surface of the protective top plate 5 is provided with circumferentially distributed sliding holes 10, and the protective top plate 5 is provided with radially arranged sliding grooves 9 on the inner side of each sliding hole 10. The position of each sliding hole 10 corresponds to the position of each mounting groove 13. A sliding column 11 is provided on the top of the buffer block 7. The sliding column 11 passes through the sliding hole 10 and extends into the sliding groove 9. The end block 12 arranged at the top end of the sliding column 11 slides radially along the groove of the sliding groove 9.
[0025] In order to improve the anti-collision capability of the entire capacitor product, a gap is reserved between the mounting groove 13 and the buffer block 7, and the gap is pre-filled with a buffer pad 16, and the buffer pad 16 can be first bonded into the mounting groove 13, and then the buffer block 7 is installed. In addition, the bottom groove wall of the mounting groove 13 is designed as a slope 14, and correspondingly, the lower surface of the buffer block 7 is designed as an inclined surface that slides and fits with the slope 14.
[0026] The outer surface of each buffer block 7 is designed to be an arc surface consistent with the outer peripheral surface contour of the housing 1. The buffer block 7 and the housing 1 can form a whole, which can ensure that the finished capacitor has a good appearance. In addition, in the actual application process, since the outer surface of each buffer block 7 protrudes slightly outward, when the capacitor is hit, the first thing to be hit should be the protruding buffer blocks 7. The circumferentially distributed buffer blocks 7 can effectively buffer collisions from all directions.
[0027] Combined with Figure 4 When the finished capacitor is hit in a certain direction, the impact force in that direction will directly act on the corresponding buffer block 7, and the buffer block 7 will be pushed inward. The end block 12 on the top of the buffer block 7 will slide radially along the slide groove 9. At the same time, the buffer block 7 will be moved downward by the connecting rod 8. Here, the slide groove 9 has a certain depth. Figure 4 The distance D in the middle is the depth of the downward movement of the buffer block 7. The buffer block 7 is pushed inward and covers the buffer pad 16, and the buffer pad 16 can be used to buffer the impact force; the buffer block 7 is pushed downward and covers the slope 14 at the bottom of the installation groove 13, and the slope 14 and the lower surface of the buffer block 7 can be used to buffer the impact force. The combination of the above two impact resistance forms can effectively prevent collision and buffer, reduce the impact of collision on the capacitor, and ultimately improve the protection of the capacitor.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
