Abstract

The invention relates to a connector, especially relates to the connector used for a lawn mower and belongs to the alloy material technology field. The connector comprises a main shaft. An end surface of a main shaft top end is an arc surface. An end surface of a main shaft bottom end is a plane. A central section of the main shaft is outwardly extended to form one cylindrical ring along a radial direction. The main shaft is provided with a conical ring. The conical ring is located between the main shaft bottom end and the cylindrical ring. An external diameter of the conical ring is gradually increased from the main shaft bottom end to the main shaft top end. The connector is made of a three-dimensional braided carbon fiber / tin phosphor bronze composite material. The composite material comprises a three-dimensional braided carbon fiber with a 5-10% volume percent content and tin phosphor bronze with a 90-95% volume percent content. The connector of the invention simultaneously possesses advantages of two materials of the carbon fiber and the tin phosphor bronze. Through a proportion of the two and a specific manufacturing method, conductivity of the connector is not reduced, simultaneously mechanical properties of intensity, hardness and the like of the connector, and wear resistance, thermal fatigue resistance, stress relaxation resistance and the like are increased. Working efficiency and a service life of the connector are improved and prolonged.

Description

technical field [0001] The invention relates to a connector, in particular to a connector for a lawn mower, and belongs to the technical field of alloy materials. Background technique [0002] A connector is a common component in electronic engineering. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the intended function. . Connectors are an indispensable part of electronic equipment. If you follow the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing, and there are various forms of connectors depending on the application object, frequency, power, application environment, etc. For example, there is a big difference between the light connector on the field and the hard drive connector and the rocket connector. But no matter what kind of connector, it is necessary to ensure that...
