Abstract

The invention relates to an automatic jump connector for a street lamp, and belongs to the technical field of alloy materials. The connector sequentially comprises cylindrical lower end part, middle part and upper end part from bottom to top, wherein the diameter of the lower end part is greater than that of the middle part; the diameter of the middle part is greater than that of the upper end part; a section cutting plane is arranged at the bottom end of the lower end part; the cutting direction of the section cutting plane inclines from the external surface of the lower end part to the center of the lower end part from top to bottom; an urgent surface is a cambered surface; the lower end of the urgent surface is flush with the bottom surface of the lower end part; the connector comprises a ceramic filling part and a metal layer; the metal layer is arranged on an outer layer of the ceramic filling part and is a tin-phosphor bronze layer; and the metal layer is prepared from the following components in percentage by weight: 2.7%-3.3% of Zn, 3.5%-4.5% of Sn, 0.01%-0.03% of P, 0.01%-0.05% of Fe, 0.5%-1% of Ni, 0.05%-0.1% of Si, 0.1%-0.5% of a rare earth element, less than 0.02% of Pb, less than 0.002% of Al, less than 0.002% of Sb, less than 0.002% of Bi and the balance of Cu and inevitable impurity elements. The connector has relatively high conductivity, excellent strength, high-temperature usability, wear-resisting property, thermal fatigue resistance, stress relaxation resistance and the like.

Description

Technical field [0001] The invention relates to a connector, in particular to a street lamp automatic jump connector, belonging to the technical field of alloy materials. Background technique [0002] A connector is a common component in electronic engineering. Its function is very simple: it builds a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. . Connectors are an indispensable part of electronic equipment. Observing along the path of current flow, one or more connectors will always be found. Connector forms and structures are ever-changing. There are various types of connectors depending on the application object, frequency, power, and application environment. For example, the connectors for lighting on the court and the connectors for hard drives, and the connectors for lighting rockets are quite different. But no matter what kind of connector, it is necessar...
