Description

Cable connection terminal and main board comprising same

Technical Field

The disclosure relates to the field of electrical technology, and in particular to a cable connection terminal and a motherboard including the cable connection terminal.

Background

Wire nose (DT) is a standard commonly used in the electrical arts, and fitting manufacturers often make it in standardized fashion. When cables with different specifications are arranged, the wire nose with corresponding size can be selected according to the standard. In order to connect a cable to an electrical device, it is generally necessary to pass through a connection hole of a wire nose with a screw and screw to a connection terminal or the like of the electrical device.

A printed circuit board may be provided in the electrical device and a ground cable and a power input cable may be included in the conventional cable. Problems are encountered in connecting these cables, such as bending and torsional stresses of the cables which can make it difficult to align the wire nose with the terminals of the printed circuit board and thus inconvenient to pass through the screws. When the printed circuit board is horizontally placed, the screw and the screw hole are slightly easy to align; when the printed circuit board is placed obliquely or vertically, the screw is easy to deviate and fall under the action of gravity. When an operator operates, one hand can be occupied by the screwdriver, the other hand needs to hold the cable to ensure the alignment of hole sites, and the placement stability of the screws is difficult to ensure under the condition that both hands are occupied. Once the screw is inclined and falls, repeated operation is needed, trial and error cost is high, operation time is long, and maintenance is inconvenient.

Products with a vertical layout of the main board belong to a relatively conventional layout mode on a hard disk video recorder or a server which relates to a multi-disk machine type, and even the main board with the horizontal layout can be dropped. Some special-shaped rapid wiring designs are now visible, but the structure of the wire nose needs to be modified, and the customized design is difficult and high in cost. In most practical situations, the cable and the wire nose are designed using standard designs, so a fast cable connection manner capable of adapting to the standard wire nose is needed.
