Embodiment Construction

[0040] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0041] The present invention provides a power distribution box, which can be used, for example, as a printer panel power distribution box in the DCS project of Fuqing Nuclear Power Unit 5 and Unit 6 of Siemens Power Station Automation Co., Ltd. figure 1 A preferred embodiment according to the invention is shown by way of example.

[0042] refer to figure 1 and figure 2 , the power distribution box 100 includes a casing 1 and a power distribution component 2 . The housing 1 has a wall, which defines an inner cavity 11 , and has a plurality of through holes communicating the inner cavity 11 with the outside of the housing 1 . The power distribution part 2 is arranged in the inner cavity 11 of the housing 1, and the power distri...

Abstract

The invention provides a distribution box. The distribution box comprises a distribution component and a shell. The distribution box is configured to enable each of the plurality of cables to pass through each of a plurality of through holes, and one end of each cable is inserted into a wiring terminal of power distribution component so that the cable is electrically connected with the distribution component, and the other end of each cable is located outside the shell; and the axis of each through hole in the plurality of through holes is collinear with the axis of each wiring terminal in the plurality of wiring terminals. According to the distribution box provided by the technical schemes provided by the invention, the axes of the through holes for introducing the cables of the distribution box are collinear with the axes of the wiring terminals in plugging connection with the cables, namely, the through holes directly face the wiring terminals, and the parts, from the through holes to the wiring terminals, of the cables cannot be bent. After the plurality of cables are connected into the distribution box, the cables in all sections in the distribution box are parallel to one another and are not prone to being staggered, the cables are not bent and are not prone to being damaged, and the service life of the cables can be prolonged.

Description

technical field [0001] The invention relates to a power distribution box. Background technique [0002] The distribution box in the existing electric power project is usually a cuboid distribution box, the gap between the distribution terminal in the box body and the box wall is narrow, and the through hole on the box body for introducing cables and the distribution terminal Not facing directly, the cable needs to be bent after being introduced into the box through the through hole of the box before it can be plugged into the power distribution terminal. Especially after the cable enters from the through hole on the wall of the box body, the box cover should be fixed around the screw opening position, where obvious bending usually occurs. This is not conducive to the wiring operation, and it is also easy to damage the cable and affect the service life of the cable. [0003] Therefore, it is necessary to provide a power distribution box to at least partially solve the above...
