An mlcc support capacitor welding protection fixture

Abstract

This utility model discloses a welding protection fixture for MLCC (Multi-Layer Ceramic Capacitor) brackets, including an upper clamping plate and a lower clamping plate. The upper and lower clamping plates are arranged vertically opposite each other, and positioning grooves are equidistantly spaced at the center of the inner side of the lower clamping plate. The surfaces of the upper and lower clamping plates are uniformly coated with a Teflon layer. This utility model, by applying a Teflon coating to the surfaces of the upper and lower clamping plates, forms a fixture with a thermal stress buffer layer, thereby releasing thermal stress during the welding process of MLCC products, reducing the risk of damage to the ceramic body, and thus reducing usage costs. Furthermore, the locking between the upper and lower clamping plates is achieved through a threaded tube and a threaded rod connected by threads. If the threaded rod breaks off inside the threaded tube, the threaded tube can be directly disassembled. Compared to breaking off inside the threaded holes on the upper and lower clamping plates, only a smaller threaded tube structure needs to be replaced, further reducing costs.

Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a welding protection clamp for MLCC bracket capacitors. Background Technology

[0002] MLCC bracket capacitors are composite electronic devices that use multilayer ceramic capacitors (MLCCs) as the core component and achieve electrical connection and mechanical fixation through a special bracket structure. Welding is one of the processing techniques for this capacitor, and during the welding process, a fixture is usually used for positioning.

[0003] Currently, the fixtures used in the welding of MLCC capacitors are mainly made of mold steel or stainless steel. When using them, the assembled capacitors are placed in the fixtures to maintain the stability of the state and structure during the welding process. However, this process cannot release thermal stress, which can damage the ceramic body and increase costs. Therefore, there is a need to provide a protective fixture that can solve the above-mentioned drawbacks and improve the effect. Utility Model Content

[0004] The purpose of this utility model is to provide a welding protection clamp for MLCC (Multi-Layer Ceramic Capacitor) brackets, thereby solving the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a welding protection clamp for MLCC bracket capacitors, comprising:

[0006] The upper clamping plate and the lower clamping plate are arranged opposite each other, and the lower clamping plate has positioning grooves at equal intervals at the center of its inner side. The surfaces of the upper clamping plate and the lower clamping plate are uniformly coated with Teflon.

[0007] Furthermore, the upper clamping plate has a through hole extending to the end of the lower clamping plate, and a threaded tube is provided in the through hole, with a threaded rod threadedly connected inside the threaded tube.

[0008] Furthermore, the upper and lower ends of the threaded tube are threadedly connected to threaded rings, and the inner sides of the threaded rings extend into the upper and lower clamping plates respectively.

[0009] Furthermore, the top of the threaded rod is provided with a top head, and the inner side of the top head abuts against the upper clamping plate.

[0010] Furthermore, the lower part of the threaded rod is threaded with a wing nut, and the inner side of the wing nut abuts against the lower clamping plate.

[0011] Furthermore, positioning holes are equidistantly provided in the middle of the upper clamping plate.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes upper and lower clamping plates to position MLCC capacitors to be welded in conjunction with positioning grooves.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-3 As shown, this utility model is a welding protection clamp for MLCC bracket capacitors, comprising:

[0023] The upper clamping plate 11 and the lower clamping plate 12 are arranged opposite each other, and the lower clamping plate 12 has a positioning groove 13 equidistantly opened in the center of the inner side. The surfaces of the upper clamping plate 11 and the lower clamping plate 12 are uniformly provided with a Teflon coating 14.

[0024] Positioning holes 15 are equidistantly provided in the middle of the upper clamping plate 11;

[0025] The positioning holes 15 and positioning grooves 13 support the MLCC bracket capacitor. The upper clamping plate 11 and lower clamping plate 12, after being locked, exert force on the MLCC bracket capacitor to fix the structure during the welding process. The Teflon coating 14 forms a tooling fixture with a thermal stress buffer layer to release the thermal stress during the welding process of the MLCC product, reduce the risk of ceramic body damage, and thus reduce the cost of use.

[0026] The upper clamping plate 11 has a through hole 16 extending to the end of the lower clamping plate 12, and a threaded tube 17 is provided in the through hole 16, and a threaded rod 19 is threadedly connected in the threaded tube 17.

[0027] The through hole 16 is used to support the threaded tube 17. The threaded connection between the threaded tube 17 and the threaded rod 19 can be used to lock the upper clamping plate 11 and the lower clamping plate 12. The threaded connection can also be used to adjust the distance between the upper clamping plate 11 and the lower clamping plate 12 to meet the needs of fixing the MLCC bracket capacitor.

[0028] The upper and lower ends of the threaded tube 17 are threadedly connected to threaded rings 18, and the inner sides of the threaded rings 18 extend into the upper clamping plate 11 and the lower clamping plate 12 respectively.

[0029] The threaded ring 18 connects the threaded tube 17 to the upper clamping plate 11 and the lower clamping plate 12 respectively. The threaded connection allows for easy and convenient disassembly of the threaded tube 17 in the event of breakage of the threaded rod 19, without affecting subsequent use.

[0030] The top of the threaded rod 19 is provided with a top head 111, and the inner side of the top head 111 abuts against the upper clamping plate 11.

[0031] The lower part of the threaded rod 19 is threadedly connected to a wing nut 110, and the inner side of the wing nut 110 abuts against the lower clamping plate 12.

[0032] The contact between the top head 111 and the upper clamping plate 11, and the contact between the wing nut 110 and the lower clamping plate 12, ensure a tight connection between the upper clamping plate 11 and the lower clamping plate 12.

[0033] Working principle: When fixing the MLCC bracket capacitor to be welded, the upper part of the capacitor is inserted into the positioning hole 15, and the lower part is placed in the positioning groove 13. At this time, the threaded tube 17 is installed in the through hole 16 at the end of the upper clamping plate 11 and the lower clamping plate 12 using the threaded ring 18. The threaded rod 19 is then threaded into the threaded tube 17. By utilizing the thread expansion and contraction characteristics, the distance between the upper clamping plate 11 and the lower clamping plate 12 is adjusted to adapt to the capacitor. The contact between the top head 111, the wing nut 110 and the upper clamping plate 11 and the lower clamping plate 12 ensures the stability of the structure of the upper clamping plate 11 and the lower clamping plate 12, thus ensuring the stability of the capacitor structure. Welding processing can then be carried out.

[0034] This solution creates a tooling fixture with a thermal stress buffer layer by applying a Teflon coating 14 to the surfaces of the upper clamping plate 11 and the lower clamping plate 12. This releases the thermal stress during the welding process of MLCC products, reduces the risk of damage to the ceramic body, and thus reduces the cost of use. Furthermore, the locking between the upper clamping plate 11 and the lower clamping plate 12 is accomplished by using a threaded tube 17 and a threaded rod 19 connected by threads. If the threaded rod 19 breaks off inside the threaded tube 17, the threaded tube 17 can be directly disassembled. Compared to breaking off inside the threaded holes on the upper clamping plate 11 and the lower clamping plate 12, only the smaller threaded tube 17 structure needs to be replaced, further reducing costs.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
