Problems solved by technology
When the heat generation of the wiring device is too large, the insulation level of the wiring device itself will be reduced until an electrical short circuit accident occurs, which can cause a regenerative fire accident
[0004] In the prior art, regular fastening of wiring devices is usually used to avoid similar accidents. This traditional working method is not only time-consuming and laborious, but also difficult to solve the problem fundamentally.

Embodiment Construction
[0021] Such as figure 1 , 2 As shown, an anti-loose guide part, the guide part 10 is in the shape of a flat sheet or plate, both ends of the guide part 10 are set as connection ends 11, and the two connection ends 11 are self-guiding One side plate of the component 10 faces the other side plate in a bent shape, and the bending directions of the two connecting ends 11 are the same.
[0022] There are many ways to realize that the two connecting ends 11 are bent from one side plate to the other side plate of the flow guiding component 10 , such as V-shaped, W-shaped or wavy bent.
[0023] preferred, such as figure 2 As shown, the two connecting ends 11 are in a smooth arc shape from one side plate surface to the other side plate surface of the flow guide member 10 .
[0024] The arc-shaped transition section will enable the connection end 11 to have a larger contact area with the screw 30, thereby ensuring the fastness of the entire wiring device.
[0025] Further, the two ...

The invention belongs to the field of wiring techniques of electrical equipment, and particularly relates to an anti-loosening diversion component and a large-current anti-loosening wiring device with the same. The diversion component is in the shape of a flat sheet or plate, the two ends of the diversion component are both set as connecting ends, the two connecting ends are bent from one side plate surface to the other side plate surface of the diversion component, and the bending directions of the two connecting ends are same. The wiring device comprises nuts and screws, the two connecting ends of the diversion component are both arranged in the nuts, and the upsides of the two nuts are respectively provided with a screw hole, the screws pass through the screw holes from top to bottom and then are tightly propped against slots on the connecting ends of the diversion component. According to the invention, due to the natural restoration of the bent connecting ends of the diversion component, a high connecting and fastening degree is always kept between the wiring device and a guide line, thereby achieving the purpose of keeping a contact resistance unchanged so as to effectively avoid the occurrence of accidents.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment wiring, and in particular relates to an anti-loosening guide part and a large-current anti-loosening wiring device containing the part. Background technique [0002] At present, high-power electrical equipment is widely used, and the wiring device inside the electrical cabinet that supplies power to the electrical equipment has been widely used. In the prior art, the fastening of each terminal of the wiring device is realized by the thread engagement of the screw and the nut. [0003] In actual use, as the seasons change, the external ambient temperature also changes from hot to cold. The screws and nuts in the wiring device will also expand and contract as the temperature of the external environment changes. Under the action of thermal expansion and contraction, the originally fastened wiring device will gradually loosen, so that the contact resistance between the wire and the wiri...
