Embodiment Construction

[0072] An electromagnetic relay according to a specific embodiment has a relay contact that is opened or closed by supplying power to an exciting coil, and suppresses an inrush current to the motor circuit by supplying power to the motor circuit through a predetermined resistor when the starter device is activated, and After the specified time has elapsed from the start of power supply, the relay contact is closed to short-circuit the resistor, thereby supplying power to the motor circuit.

[0073] In addition, in the manufacturing method of the electromagnetic relay according to the specific embodiment, the first type and the second type are respectively manufactured by using common components shared by both the first type and the second type, wherein the first type is A type having an IC functioning as a delay unit inside the electromagnetic relay, and the second type is a type having a function as a delay unit outside the electromagnetic relay, and the delay unit is set from...

Abstract

The invention relates to an electromagnetic relay and a method for making the same. During the procedure of assembling the metal members of the auxiliary electromagnetic relay, each terminal of the IC (12) and the metal members (68) are made to be jointed via conduction under the condition of manufacturing the first auxiliary electromagnetic relay, thereby making them integrally formed with the metal members (68). During the procedure of removing the useless part, the useless part to-be-removed is changed according to the condition of making the first auxiliary electromagnetic relay and the second auxiliary electromagnetic relay. Therefore, under the condition of making the first auxiliary electromagnetic relay, the IC (12) is embedded as the delay unit. Therefore, under the condition of building a delay unit inside the auxiliary electromagnetic relay, the heat resistance of the auxiliary electromagnetic relay can be improved. In addition, by employing the common components and reducing the assembling problem of different components, the first and second auxiliary electromagnetic relays can be respectively made, thereby cutting the manufacturing cost.

Description

technical field [0001] The present invention mainly relates to an electromagnetic relay, and particularly relates to an auxiliary electromagnetic relay for suppressing an inrush current generated when power supply to a motor circuit of a vehicle starter is started. Background technique [0002] Conventionally, a starter device for starting an internal combustion engine of a vehicle includes an electromagnetic relay that has a function of pushing a pinion gear toward a ring gear of the internal combustion engine and a function of turning on or off power supply to a motor circuit. [0003] However, when the starter is started, the electromagnetic relay is turned on to supply power to the motor circuit, and a large current called "inrush current" flows from the battery to the motor circuit. There is concern about the phenomenon of so-called "momentary disconnection (momentary interruption)" in which electrical equipment such as measuring instruments and audio equipment stops in...
