In some embodiments, described riveting process encapsulation side plate, upper cover and lower cover mode press shaping for once.
In some embodiments, described salient point and conductor integrated punching shaping.
In some embodiments, described side plate quantity is two panels, and described two panels side plate adopts symmetric mode to arrange, and the one side that described two panels side plate is relative is provided with the shackle member for setting up described conductor; The two ends up and down of described two panels side plate are provided with hook-like groove, and the outer of each hook-like groove is provided with flange, and the hook-like groove opening of two panels side plate is relative.
As can be seen from above, the novel bus slot device that the utility model provides, adopt the conductor that thickness is less, under the prerequisite ensureing current-carrying cross section, adopt the conductor of suitable width, the faying surface of conductor has carried out salient point process, can effectively improve current-carrying efficiency and machining accuracy, strengthen the reliability of contact, reduce the probability that kelvin effect produces, improve the overall performance of bus, and operation is easy, greatly improves and manufacture efficiency.Described salient point adopts mould one-shot forming.
Further, described novel bus slot device is assembled shell by riveting process, simplifies assembling process, greatly can improve efficiency of assembling.Preferably, it is shaping that described riveted joint can adopt dedicated hydraulic equipment once to press, and utilizes material own tension to realize the fastening of shell; The bus duct shell assembled by adopting new fastening procedure, can be the protection that inner conductor provides solid, good looking appearance, providing good fastening performance while, manufactures and becomes simple, greatly improves and manufactures efficiency.
