Description

A kind of hard bus connection structure

Technical field

The utility model relates to technical field of electricity, especially a kind of hard bus connection structure.

Background technique

Hard bus is one of the main installation elements produced in power distribution cabinet, and hard bus is in addition to that should have enough contact surfaces Outside, the connection between bus should ensure that enough and lasting contact pressures and not make to generate permanent deformation, its quality is straight Connect the electric property for influencing equipment.

Since the assembly rework rate of domestic hard bus is high, certain economic loss can be caused to production and operation, and drop Low power supply reliability.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of hard bus connection structures, can be improved hard bus company The reliability connect.

A kind of hard bus connection structure that in order to solve the above technical problems, the technical scheme adopted by the utility model is:, packet Include the first hard bus and the second hard bus, the faying surface of the first hard bus and the second hard bus is embossing face, the first hard bus with Second hard bus is equipped with through-hole, and bolt is equipped in through-hole, and one end of bolt is equipped with nut, and longitudinal open is equipped between through-hole Slot.

Preferably, the lateral surface of first hard bus and the second hard bus is equipped with zinc coat.

Preferably, conductive paste is coated on the embossing face.

Preferably, the both ends of the bolt are respectively equipped with gasket, and washer is additionally provided between gasket and nut.

Preferably, the width of the fluting is 1mm to 2mm.

The utility model provides a kind of hard bus connection structure, when hard bus faying surface it is more smooth, contact surface is more, The resistance of hard bus faying surface is reduced, while making the connection of hard bus stronger, is unlikely to deform.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and examples:

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the side view of the utility model hard bus.

Specific embodiment

As shown in Figs. 1-2, a kind of hard bus connection structure, including the first hard bus 1 and the second hard bus 2, first is hard female Line 1 and the faying surface of the second hard bus 2 are embossing face 3, the first hard bus 1 and the second hard bus 2 equipped with through-hole 4, in through-hole 4 Equipped with bolt 5, one end of bolt 5 is equipped with nut 6, and longitudinal fluting 7 is equipped between through-hole 4.Using embossing face overlap joint first is that Contact surface is smoothed, second is that increasing the contact points of contact surface, to achieve the purpose that reduce contact resistance.Make faying surface simultaneously Temperature also reduces.When bolt, nut apply biggish pressure to hard bus, hard bus is existing since mechanical stress can generate warpage As, prevent hard bus from fitting closely increase resistance, using the method for fluting, in the case where not influencing the preceding topic of bus current carrying area, Overcome warping phenomenon.

Preferably, the lateral surface of first hard bus 1 and the second hard bus 2 is equipped with zinc coat 8.Zinc coat can be placed The lateral surface of hard bus is not corroded.

Preferably, conductive paste is coated on the embossing face 3.Being coated with conductive paste further reduces resistance.

Preferably, the both ends of the bolt 5 are respectively equipped with gasket 9, and washer 10 is additionally provided between gasket 9 and nut 6.

Preferably, the width of the fluting is 1mm to 2mm.

When the utility model is used, embossing face is coated with conductive paste now, then two embossing faces are in contact, alignment is logical Hole compresses, and is then fastened using bolt.

The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the technical solution that the protection scope of the utility model should be recorded with claim, the technical solution recorded including claim The equivalents of middle technical characteristic are protection scope.Equivalent replacement i.e. within this range is improved, also in the utility model Protection scope within.
