detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present utility model are only relative concepts or refer to the normal use state of the product, and should not be regarded as restrictive of.

The utility model provides an electrical connection structure, which can be applied to electrical control equipment such as an AC system of a substation, an AC-DC integrated power supply system, a control cabinet, a power distribution cabinet, and a distribution box.

As shown in FIGS. 1 to 5 , the electrical connection structure includes a first conductive member 10, a second conductive member 20, and a locking mechanism for locking and electrically connecting the first conductive member 10 and the second conductive member 20. Fastening assembly 30, fastening assembly 30 comprises bolt 31 and the nut 32 that cooperates with bolt 31, and bolt 31 comprises interconnected screw head 311 and screw rod 312, and screw rod 312 and nut 32 screw fit; In this implementation, as shown As shown in 1, the first conductive member 10 is an incoming wire transfer copper bar, and the second wire is a vertical bus bar. In the utility model, the side of the first conductive member 10 is provided with a bayonet 11 for the screw rod 312 to pass through, and the second conductive member 20 is provided with a chute 21 for the screw head 311 to slide in and limit the rotation of the screw head 311. The diameter of the mouth 11 is larger than the diameter of the screw 312 , and the diameter of the bayonet 11 is smaller than the outer diameter of the nut 32 .

Based on this structure, the assembly process is as follows: firstly, the bayonet 11 of the first conductive member 10 is docked with the notch of the chute 21 in the second conductive member, and then the screw head 311 is slid into the sliding slot of the second conductive member 20. Slot 21, slide the screw rod 312 into the bayonet 11 of the first conductive member 10. In this process, it is not necessary to take out the pre-nut 32 from the screw rod 312; secondly, tighten the nut 32 again, so that the first conductive member 10 It is in close contact with the second conductive element 20 and realizes the electrical connection between the first conductive element 10 and the second conductive element 20 .

Therefore, the utility model does not need to take out the nut 32 from the screw rod 312 in advance, at the same time, it also reduces the process of tightening the nut 32 again, saves the process of fully matching the bolt 31 and the nut 32, and improves the electrical connection structure. installation efficiency.
