Description

Technical Field

[0001] The utility model belongs to the technical field of potting tooling, and in particular relates to a capacitor potting fixing tooling. Background Art

[0002] Potting is the process of mechanically or manually pouring liquid compounds into devices containing electronic components and circuits, and solidifying them at room temperature or under heating conditions to become thermosetting polymer insulating materials with excellent performance. It is used to strengthen the integrity of electronic devices and improve their resistance to external impact and vibration; improve the insulation between internal components and circuits, which is conducive to the miniaturization and lightweight of devices; avoid direct exposure of components and circuits, improve the waterproof and moisture-proof properties of devices, and improve performance and stability parameters.

[0003] At present, the potting and fixing tooling of capacitors is to surround and fix the outside of the capacitor through the combination of column baffles and bolts. Since the tooling design can usually only be adapted for the shell of the same specification, it is difficult to meet the fixing requirements when the size of the capacitor shell changes. As a result, even if there are some dimensional changes in capacitors of different specifications, different tooling needs to be reset and manufactured to meet the requirements of potting stability of capacitors of different sizes. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a capacitor potting and fixing tooling to solve the problem that the potting tooling has poor adaptability to capacitors of different specifications.

Multiple limiting plates rest around the capacitor to limit and fix it. At the same time, due to the elastic deformation of the limiting plates, capacitors of different sizes placed in the clamping space can be well clamped.

[0032] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0033] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0034] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0036] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] like Figure 1-2 As shown, the utility model provides a capacitor potting and fixing tool, which includes: a base, four telescopic rods, a first top frame, and four limiting plates.

[0038] Four telescopic rods are vertically arranged on the base, located at the four corners of the base, and a first top frame is arranged on the top of the telescopic rods. The first top frame is a frame-type structure, and four limit plates are fixed on the inner wall of the frame-type structure. Specifically, the top of the limit plate is connected to the inner wall of the first top frame, and the bottom extends obliquely downward and inward. The limit plate is used to abut against the outer wall of the capacitor after generating elastic deformation. The four limit plates are surrounded to form a clamping space for clamping the capacitor. Since the limit plate is elastic, the clamping space can adapt to capacitors of different sizes through elastic deformation.

[0039] A clamping space for clamping the capacitor is formed by fixing multiple limiting plates on the inner side of the first top frame. After the capacitor is placed in the clamping space, the bottom of the limiting plate is a free end, so after elastic deformation, the bottom of the limiting plate rests on the outer wall of the capacitor. Multiple limiting plates rest around the capacitor to limit and fix it. At the same time, due to the elastic deformation of the limiting plates, capacitors of different sizes placed in the clamping space can be well clamped.

[0040] This embodiment also includes a second top frame and two pairs of pressing plates, wherein a pair of pressing plates is composed of two pressing plates arranged opposite to each other, and a total of four pressing plates are fixed on the four sides of the first top frame.

[0041] The second top frame is crimped and fixed to the top of the first top frame, and the pressure plate is clamped between the first top frame and the second top frame and fixed. The pressure plate is used to be crimped to the top edge of the capacitor to ensure that the capacitor confined in the clamping space remains more stable.

[0042] A sliding groove pointing to the center of the clamping space is opened on the top of the first top frame, and the pressure plate is slidably clamped in the sliding groove. The clamping plate slidingly set in the sliding groove can reciprocate along the direction toward the center of the clamping space. When the clamping plate is pushed inward, the inner end of the pressure plate can be pressed on the top end edge of the smaller capacitor. When the clamping plate is pulled outward, the inner end of the pressure plate can be pressed on the top end edge of the slightly larger capacitor. The position of the pressure plate can be adapted and adjusted according to capacitors of different sizes.

[0043] The outer end of the pressing plate is folded to form a limiting end, which not only facilitates the push-pull operation, but also prevents the clamping plate from sliding too far inward and out of the sliding groove.

[0044] In this embodiment, the telescopic rod includes: a bottom sleeve, a shaft sleeve and a stud.

[0045] The bottom sleeve is arranged on the base. The bottom sleeve is a hollow tubular structure and is vertically fixed on the base. The shaft sleeve is rotatably connected to the top opening of the bottom sleeve. The shaft sleeve and the bottom sleeve are circumferentially rotatably connected, and the two are axially limited. The inner wall of the shaft sleeve is provided with an internal thread. The stud is screwed into the shaft sleeve. The top of the stud is connected to the first top frame. By rotating the shaft sleeve, the stud can be driven to rotate up and down in the shaft sleeve, thereby adjusting the length of the telescopic rod to meet the needs of capacitors of different heights.

[0046] A convex stop is provided at the top of the first top frame, and a concave stop matching the convex stop is provided at the bottom of the second top frame. The convex stop is provided at the four corners of the top of the first top frame, and the concave stop is provided at the four corners of the bottom of the second top frame, so that the first top frame and the second top frame can be better positioned and matched, and the four corners of the first top frame and the second top frame are fastened and connected by bolts to clamp the pressure plate.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
