The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.
As shown in fig. 1, the present utility model discloses a non-isolated DC-DC converter connection structure, which comprises a case 100, an input terminal connection part 200 and an output terminal connection part 300, wherein the input terminal connection part 200 and the output terminal connection part 300 are disposed at the same side of the case 100.
A non-isolated DC-DC converter connection includes an input connection 200 and an output connection 300. In the buck dc-dc converter, the input end connection portion 200 is a high-voltage input end connection portion, the output end connection portion 300 is a low-voltage output end connection portion, and the input end connection portion 200 and the output end connection portion 300 are disposed at the same side of the converter junction box body 100.
Further preferably, in other embodiments of the present application, the input end connection portion 200 and the output end connection portion 300 may be alternatively fastened to the junction box body 100 directly. A clamping groove is arranged at the lower side of the input end connecting part 200, and similarly, a clamping groove is also arranged at the lower side of the output end connecting part 300, and a clamping part is arranged at the corresponding position of the box body 100 for connecting the input end connecting part 200 and the output end connecting part 300. Through the draw-in groove that sets up in input connecting portion 200 and output connecting portion 300 downside and the joint portion that sets up in box body 100, can directly with input connecting portion 200 and output connecting portion 300 joint on box body 100, and input connecting portion 200 and output connecting portion 300 are the level joint side by side on box body 100. By the aid of the connection mode, the input end connection part 200 and the output end connection part 300 are convenient to mount and dismount, good in connection strength and good in connection reliability.
Further preferably, the input end connection portion 200 may be selectively snapped with the output end connection portion 300 in other embodiments of the present application. The clamping groove is formed in one side of the input end connecting portion 200, the clamping portion is correspondingly formed in one side, connected with the input end connecting portion 200, of the output end connecting portion 300, and the output end connecting portion 300 can be directly clamped at the input end connecting portion 200 through the clamping groove formed in the input end connecting portion 200 and the clamping portion formed in the output end connecting portion 300. By mutually clamping the input end connection part 200 and the output end connection part 300, the connection strength of the input end connection part 300 and the output end connection part 300 is improved.
In other embodiments of the present application, a groove may be optionally disposed on the clamping portion of the output end connecting portion 300 and the input end connecting portion 200, where the groove is disposed at the middle position of the clamping portion, and the groove is disposed such that two connecting surfaces and a groove located in the middle of the two connecting surfaces exist on the clamping portion of the output end connecting portion 300. The clamping portion of the output end connecting portion 300 is set to be two connecting surfaces and a groove, and compared with the clamping portion without the groove, the connecting surface of the clamping groove formed in the input end connecting portion 200 in a connecting mode is reduced, namely, the connection of the clamping portion and the clamping groove is conducted from the portion, which is completely attached to the connecting surface, of the connecting surface to the portion, which is attached to the connecting surface. Because the connection area of the clamping part and the clamping groove is reduced, the connection strength of the input end connection part 200 and the output end connection part 300 is ensured, and the installation and the disassembly of the output end connection part 300 are more convenient.
Further preferably, in other embodiments of the present application, the mounting portion 101 may be optionally provided on the box body 100, one side of the output end connection portion 300 is clamped to the input end connection portion 200, and the other side of the output end connection portion 300 is clamped to the mounting portion 100. The mounting portion 101 of the box body 100 is a portion of the junction box body 100 for mounting and connection. In the buck dc-dc converter, the input terminal connection 200 is a high voltage input terminal and the output terminal connection 300 is a low voltage output terminal. The output terminal connecting portion 300 is disposed beside the mounting portion 101, and since the mounting portion 101 is a portion for mounting and dismounting the junction box, the output terminal connecting portion 200, which is a relatively low-voltage portion, is disposed beside the mounting portion, so that the junction box is safer in mounting or dismounting. Similarly, in the boost dc-dc converter, the input part is low voltage input, and the output part is high voltage output, so that the low voltage input part can be arranged beside the mounting part 101, and the safety is higher when the mounting part 101 is used for mounting the junction box body of the connection converter.
Further preferably, in other embodiments of the present application, the guiding portion 301 may be optionally disposed outside the output end connecting portion 300. The outer side of the output end connection portion 300 refers to a portion located outside the junction box body 100 when the output end connection portion 300 is clamped to the junction box body 100, and the guide portion 301 is specifically configured as a portion with an arc-shaped end. When the output terminal connection part 300 is mounted or dismounted, the arranged arc-shaped guide part 301 facilitates the operation of clamping the output terminal connection part 300 on the junction box body 100 and the operation of dismounting the output terminal connection part 300, compared with the case that the arc-shaped guide part 301 is not arranged. The arc-shaped guide portion 301 disposed outside the output end connection portion 300 has a larger difference in shape between the outside of the output end connection portion 300 and the inside thereof, compared to the case where the guide portion 300 is not disposed inside the output end connection portion 300, so that the outside and the inside of the output end connection portion 300 can be easily distinguished. Therefore, the arc-shaped guiding portion 301 is disposed on the outer side of the output end connecting portion 300, so that when the arc-shaped guiding portion is mounted on the junction box body 100 in a clamped manner, the output end connecting portion 300 is not only convenient to mount, but also has the function of distinguishing the inner side and the outer side of the output end connecting portion 300, and the mounting convenience of the output end connecting portion 300 is further improved.
While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
