Abstract

The invention discloses a moving contact component and a startup relay. The moving contact component comprises a moving iron core, a locating rod, an insulated jacket sleeved on the locating rod and a moving contact piece and a buffer spring sleeved on the insulated jacket, wherein the moving contact piece and the buffer spring are arranged in turn in a direction far away from the moving iron core; the insulated jacket is provided with a sliding area; and the moving contact piece can move to and fro within the sliding area under the action of outside force and the restore elastic force of the buffer spring. The startup relay comprises a shell, a coil component, a moving contact component of the structure, a fixed contact component and a restore spring providing the restore elastic force for the moving contact component. The moving contact piece and two fixed contact pieces can be closed in the process that the moving contact piece moves along with the moving iron core. The moving contact component and the startup relay have the advantages that the moving contact piece is directly arranged on the moving iron core, so that the overall structure is integrated and the installation and the maintenance is convenient; and the buffer spring effectively reduces abrasion caused by collision when the moving contact piece and the fixed contact pieces are closed, and ensures the service life of the moving contact piece.

Description

technical field [0001] The invention belongs to the technical field of relay structure design, and in particular relates to a moving contact assembly and a starting relay. Background technique [0002] The control circuit of the starter motor of a diesel locomotive often uses a starter relay (also called an intermediate relay), which is used to control the on-off of a large-current circuit with a small current. [0003] Patent document CN201126795Y discloses an automobile starter motor intermediate relay, which includes a coil magnetic circuit mechanism arranged in the casing, an actuator driven by the coil magnetic circuit mechanism, and a pair of connecting bolts fixed on the switch cover; Head pillar, one end of which is fixedly connected to the iron core in the coil magnetic circuit mechanism, the other end passes through the yoke plate in the coil magnetic circuit mechanism and installs the moving contact, and is connected to the switch cover through a reset compression...
