Problems solved by technology

[0014] Therefore, if Figure 26 As shown, according to the relationship between the load load of the relay and the coil attraction force, it is necessary to increase from the coil attraction force A to the coil attraction force B, and with this, it is necessary to increase the contact spring load A to the contact spring load B, resulting in consumption The problem of increasing power
In addition, in order to suppress the power consumption of the coil 105A, the load that restricts the contact spring 117, and problems such as separation and heat generation due to the vibration of the contact piece 115 occur.

Abstract

An electromagnetic relay has a mobile contact point attached to a contact member, a fixed contact point, a contact point spring that applies a biasing force on the contact member towards the fixed contact point, a guide that carries the contact member and said contact point spring, a coil that generates a pulling force when excited to move the guide and a returning spring that provides a biasing force for causing the guide to return. A mechanism is provided such that a load is generated on the contact member by the motion of the guide towards the fixed function against the returning spring immediately before the mobile contact point contacts the fixed contact point. This mechanism applies a contact point spring load of the contact point spring and the load as a contact pressure to the contact member for contacting the mobile contact point with the fixed contact point.

Description

technical field [0001] The invention relates to an electromagnetic relay which can be used as a high-capacitance power relay and the like, especially an improved contact mechanism. Background technique [0002] Such as Figure 23 to Figure 26 As shown, the existing electromagnetic relay is composed of an electromagnetic action part 101 and a contact block 102. The structure of the electromagnetic action part 101 is: an electromagnetic member 105 and an iron piece 106 are accommodated in a casing 104, and the coil 105A of the electromagnetic member 105 is excited , so that the magnetic pole portion 107 of the iron core generates an attractive force, and the iron piece 106 swings leftward around the fulcrum portion 106A. [0003] Moreover, the contact block 102 has a base 108, a guide rod 109, a terminal block 110, a return spring 111, such as Figure 25 As shown in (1), the terminal block 110 is provided with a guide bar accommodation part 118 and a contact arrangement part ...
