Abstract

PROBLEM TO BE SOLVED: To provide a sealed contact device free of degradation of the contact making performance. SOLUTION: At the peripheral surface of a movable shaft 4 of its portion located in an insert hole 3b provided in a movable contacting piece 3, a taper 4d is formed having at least an inclining angle not smaller than the tilt angle of the movable shaft 4 driving direction to the axial direction of the shaft 4 and the inclination angle of the movable contacting piece 3 to the direction perpendicular to the shaft 4 axial direction. There is no risk that the movable shaft 4 bites into the movable contacting piece 3 or receives a large friction force from the piece 3 even if the shaft 4 driving direction is tilted to the axial direction of the shaft 4 or if the movable contacting piece 3 is tilted to the direction perpendicular to the shaft 4 axial direction, and thereby a stable contact making performance is established.

Before the excitation of the coil 13 is opposed movable contact 3a is a fixed contact 2a and the contact gap L 1. When the coil 13 is excited, the movable core 8 is attracted to the fixed iron core 7 and moves, so that the movable shaft 4 which is screwed to the movable iron core 8 and then fixed by the adhesive is driven, and the movable contact 4 is moved. 3a is a contact gap L

いということが懸念される。In the above-mentioned conventional sealed contact device, when the movable contacts 3a, 3a of the movable contact 3 come into contact with the fixed contacts 2a, 2a when the contacts are turned on, the movable contact 3 moves. When the movable shaft 4 is further pushed in, the contact pressure spring 6 generates a contact pressure.
However, when the driving direction of the movable shaft 4 (the direction of arrow A in FIG. 12) has an angle α with respect to the axial direction of the movable shaft 4, the movable shaft 4 is further pushed in after the movable contact 3a contacts the fixed contact 2a. As shown in FIGS. 13A and 13B, the portion of the movable shaft 4 that slides with the insertion hole 3b of the movable contact 3 (portions C, D, and E in FIG. It is feared that the contact operation may be hindered by an increase in frictional force upon sliding or an increase in frictional force at the time of sliding, resulting in unstable contact closing performance. When the movable contact 3 has an angle β with respect to a direction perpendicular to the axial direction of the movable shaft 4 (the direction of arrow B in FIG. 12), the movable contact 3a of the movable contact 3 comes into contact with the fixed contact 2a. Sometimes, the inner peripheral surface of the insertion hole 3b of the movable contact 3 may bite with the movable shaft 4, which hinders the closing operation. As a result, there is a concern that the contact closing performance is not stable.

In addition, the movable shaft 4 does not bite into the movable contact 3 or the movable shaft 4 does not receive a large frictional force from the movable contact 3, so that stable contact closing performance can be obtained.
In addition, since a sufficient gap is provided between the movable shaft 4 and the inner peripheral surface of the insertion hole 3b, even if the metal powder of the contact material generated at the time of opening and closing the contact enters the insertion hole 3b, the movable shaft 4 and the movable contact 3 are connected to each other. There is an advantage that the opening / closing performance can be stabilized without being bitten.

In a sealed contact device having a sealing portion in which a return spring that biases the movable iron core in a direction in which the movable contact is separated from the fixed contact is housed, and a driving portion that drives the movable iron core, The gap between the insertion hole of the movable contact and the movable shaft is made larger than at least the amount by which the movable shaft can shift when the movable contact is driven, and the contact pressure spring positioned in the movable contact holder is used. Since the movable contact is positioned, the movable shaft does not contact the inner peripheral surface of the insertion hole of the movable contact, and the driving direction of the movable shaft is inclined with respect to the axial direction of the movable shaft. Even when the movable shaft is inclined with respect to the direction perpendicular to the axial direction of the movable shaft, the movable shaft does not bite into the movable contact, or the movable shaft does not receive a large frictional force from the movable contact, and is stable. With improved contact closing performance There is an effect that that. Moreover, since there is a sufficient gap between the movable shaft and the insertion hole of the movable contact, even if the metal powder of the contact material generated at the time of opening and closing the contact enters the insertion hole, the metal powder may be caught between the movable shaft and the movable contact. Therefore, there is an effect that the opening and closing performance can be stabilized.
