Detailed Description
Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 to 2 are schematic diagrams of a capacitor case with a novel welding structure before welding. The capacitor case having the novel soldering structure includes a case 10, a cover 20 connected to the case 10, and a plurality of solders 30 soldered between the case 10 and the cover 20. It is conceivable that the capacitor case having the novel welding structure further includes other functional modules, such as connection terminals provided on the case 10, fixing members provided on the case 10, etc., which are known to those skilled in the art, and will not be described herein.
The case 10 includes a channel 11, an L-shaped member 12 welded to the channel 11, and a case connecting edge 13 provided on the channel 11 and the L-shaped member 12 and welded to the case cover 20. The channel 11 and the L-shaped member 12 may be formed by a bending process. The case 20 may be made of a metal material, and preferably, the case is made of an aluminum material. The channel 11 has a first connecting edge 111 for welding with the L-shaped member 12, and the L-shaped member 12 has a second connecting edge 121 for welding with the first connecting edge 111.
One of the first connection side 111 or the second connection side 121 is provided with a first L-shaped groove 1111. The first L-shaped groove 1111 may be provided only on the first connection edge 111. When the first L-shaped groove 1111 overlaps the second overlap edge 121, a step is formed between the first and second overlap edges 111, 121. The step may be used to fill the solder 30 so that the strength of the connection between the first and second connection edges 111, 121 may be improved after the soldering is completed. It is conceivable that only the second connecting edge 121 may be provided with a first L-shaped groove. The depth of the first L-shaped slot 1111 is less than the thickness of the L-shaped member 12. The working principle of the first L-shaped groove provided on the second connecting edge 121 is the same as the working principle of the first L-shaped groove provided on the first connecting edge 111, and will not be described herein.
The case connecting edge 13 is used to connect the case cover 20, and thus will be explained below in conjunction with the case cover 20 for convenience of explanation.
The cover 20 is arranged to cover the cavity formed by the channel 11 and the L-shaped member 12 and has a cover attachment edge 21. The cover 20 is made of a metal material, and preferably, the cover 20 is made of an aluminum material.
One of the lid-engaging edge 21 or the case-lid-engaging edge 13 is provided with a second L-shaped groove 211. The second L-shaped groove 211 may be provided only on the cover overlap edge 21. The depth of the second L-shaped groove 211 is smaller than the thickness of the case 10 so that a step is formed between the cover connecting edge 21 and the case connecting edge 13 when the second L-shaped groove 211 is overlapped on the case connecting edge 13. The step can be used to fill the solder 30 so that the strength of the connection between the lid connecting edge 21 and the case connecting edge 13 can be improved after the soldering is completed.
It is conceivable that the second L-shaped groove can also be provided as far as the connecting edge 13 of the tank. The working principle of the second L-shaped groove on the case connecting edge 13 is the same as the working principle of the second L-shaped groove on the case cover connecting edge 12, and will not be described again.
The solder 30 is a solder formed when two members are welded using a solder wire, and is filled between the two members while melting the two members, thereby achieving the purpose of connecting the two members, which is well known to those skilled in the art, and will not be described herein. As is apparent from the above description, the solder 30 is filled on the step between the first and second connecting sides 111, 121 and the step between the cover connecting side 21 and the case connecting side 13.
It is conceivable that the welding mode may be filler welding or self-fluxing welding at the time of welding. The welding is performed in a seal continuous welding manner, so as to achieve the sealing purpose as much as possible, which is a technique well known to those skilled in the art, and will not be described in detail herein.
Compared with the prior art, the capacitor shell with the novel welding structure provided by the utility model fully utilizes the lap welding structure of the case shell 10 and the case cover 20, thereby not only facilitating welding, but also improving welding strength. Specifically, one of the first and second connecting sides 111 and 121 is provided with a first L-shaped groove 1111. When the first L-shaped groove 1111 is overlapped on the first and second connecting sides 111, 121, a step is formed between the first and second overlapping sides 111, 121, and the step is used to fill the solder 30, so that the connection strength between the channel member 11 and the L-shaped member 12 can be improved after the welding is completed. A second L-shaped groove 211 is provided in one of the case lid connecting side 21 and the case lid connecting side 13, and when the second L-shaped groove 211 is overlapped on the case lid connecting side 13 or the case lid connecting side 21, a step is formed between the case lid connecting side 13 and the case lid connecting side 21, which step can be used to fill the solder 30, so that the connection strength between the case lid 20 and the case 10 can be improved after the welding is completed. The utility model makes full use of the structure that the groove 11 and the L-shaped member 12 and the case shell 10 and the case cover 20 are respectively welded by the first L-shaped groove 1111 and the second L-shaped groove 211, thereby not only facilitating the welding, but also improving the welding strength.
The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
