Problems solved by technology

[0005] However, in the electromagnetic relay, metal flying powder generated when the movable contact 5 is alternately in contact with or separated from the normally closed fixed contact 8a and the normally open fixed contact 8b falls and accumulates on the base. 9 upper surface
Therefore, there is a problem that the insulation performance between the external connection terminal 11b and the external connection terminal 11c is lowered, and there is a short circuit.

Embodiment Construction

[0078] according to Figure 1A to Figure 16 The drawings illustrate embodiments of the electromagnetic relay of the present invention.

[0079] Such as Figure 1A to Figure 5C especially if Figure 3A , Figure 3B As shown, the electromagnetic relay according to the first embodiment of the present invention has a base 10 , an electromagnet unit 30 , a movable contact unit 40 , and an insulating member 50 .

[0080] The base 10 is a resin molded product having a square shape in plan view, and two normally closed fixed contact terminals 21 and normally open fixed contact terminals 22 are erected as a set at adjacent corners of the upper surface thereof. An insulating member 50 described later is attached to the normally closed fixed contact terminal 21 , while a normally open fixed contact 24 is crimped and fixed to the normally open fixed contact terminal 22 . In addition, on the upper surface of the above-mentioned base 10, a horizontal groove portion 13 is provided betwee...

Abstract

Provided is an electromagnetic relay for moving a movable contact plate (42) by electrically energizing and deenergizing a coil (33) of an electromagnet unit (30) mounted on a base (10), causing a movable contact (45) mounted on a distal end of the movable contact plate (42) to make and break contacts with a pair of stationary contact terminals (21, 22) alternately, the stationary contact terminals being implanted vertically in the base. One of the stationary contact terminals supports a stationary contact (24) and the other of the stationary contact terminals (21) supports an insulating member (50) mounted thereon.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to an insulating structure of the electromagnetic relay. Background technique [0002] In the past, as an insulating structure of an electromagnetic relay, for example, there is an electromagnetic relay, which has an iron core, a coil, a yoke, an electromagnetic block, a base, and an outer cover. The movable spring is formed by engagement, and the base is used to install and fix the electromagnetic block and the fixed contact group abutted by the movable contact, and the movable spring is electrically connected to the armature and the yoke A part of an electric circuit is characterized in that a flexible heat conductor is installed between the yoke and the cover, and the heat conductor brings the yoke and the cover into thermal contact (see Patent Document 1). [0003] In the electromagnetic relay, as shown in FIG. 1, with the excitation or demagnetization of the electromagnetic block 7 ...
