Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a combined floating limit block connection structure. Background Art

[0002] Existing electrical devices usually need to be connected to each other with multiple power terminals and signal terminals. Therefore, there are two main existing electrical connection methods. One is to lead out multiple electrical leads on the same end face or different end faces and connect them to each other through electrical leads. However, this method has messy wire output and often causes problems of misalignment of connections between different terminals. To solve the problem of misalignment, another existing connection method is to set terminals at fixed positions, which cannot move relative to each other. Two electrical devices are connected to each other through multiple fixed terminals, thereby avoiding the misalignment problem. However, the hard connection formed by this method is prone to poor contact. During contact, due to the uneven force of each terminal, most of the effective electrical connection area of ​​each terminal can only be a line or a point, and full contact cannot be guaranteed. There are problems of high resistance and severe heat at the connection. Summary of the Invention

[0003] In response to the above-mentioned technical problems, the present invention provides a combined floating limit block connection structure to solve the problem of uneven force and inability to fully contact in the existing fixed terminal electrical connection. A combined floating limit block connection structure is designed. The combined floating limit block connection structure is suitable for modular assembly of external electrical connections to ensure full contact of the connection terminals.

[0005] Furthermore, the first connecting portion is a plate-like structure, the middle portion is a plate-like structure, the second connecting portion is a J-shaped structure, and the middle portion connects the first connecting portion and the second connecting portion to form a Z-shaped structure.

[0006] Furthermore, the limiting hole is a strip-shaped hole, and the cross-section of the middle portion is adapted to the limiting hole.

[0007] Furthermore, a first limiting portion and a second limiting portion extending along the Z-axis direction are provided on both sides of the first connecting portion, and the first limiting portion and the second limiting portion are respectively in contact with the side walls of the nut on both sides.

[0008] Furthermore, limiting blocks are provided on both sides of the middle portion, and the limiting blocks are located inside the limiting hole.

[0009] Furthermore, the nut is a rectangular structure, and the connecting end plate is provided with a plurality of guide grooves for accommodating a plurality of the nuts, and the plurality of guide grooves are spaced apart from the plurality of limiting holes.

[0010] Furthermore, the connecting end plate includes an inner plate and an outer plate, a plurality of protrusions are provided on the outer side of the inner plate, the inner plate is a hollow structure on the side of the protrusions, the outer plate covers the inner plate, and the outer plate is provided with a plurality of avoidance holes at positions corresponding to the plurality of protrusions, and the avoidance holes are provided with a plurality of connecting grooves at parts corresponding to the hollow structure, and the connecting grooves and the protrusions are surrounded to form the limiting holes.

Since the electrical connection conductor and the nut are designed to float, the problem of uneven force caused by the different flatness of the external terminal can be avoided. Even if the flatness of the external terminal is different, the force problem can be offset by the floating adaptation of the electrical connection conductor and the nut, thereby ensuring that the connection between each electrical connection conductor and the external terminal is fully in contact, thereby solving the problem of gapless fit between the connection surface of the first connection part and the external electrical connection. At the same time, due to the existence of floating space during connection, the problem of poor contact caused by the uneven connection surface of the first connection part and the connection surface of the external terminal can be solved.
