高い電磁接触器ではこの構造がとられている。In the electrical contact configured as described above, an insulating film is formed on the contact surface due to dust intrusion or corrosion due to the environment in which the electromagnetic contactor or the electromagnetic relay is used, resulting in a contact resistance. Since the number of contacts increases and the contact is overheated, various measures have been taken. As an example, Japanese Utility Model Publication No. 60-1462 and Japanese Utility Model 1-2.
Japanese Patent No. 9692 proposes a contact structure in which both the movable contact and the fixed contact are slid against each other when the movable contact and the fixed contact are brought into contact with each other to destroy the insulating film. In all of these, the bottom surface of the window of the contact support, that is, the contact surface of the movable contact with the contact base is inclined in a plane perpendicular to the longitudinal direction of the contact base, and the contact base of the contact base moves from the point of contact between the movable contact and the fixed contact. The surface of the fixed contact is slid on the movable contact while the surface is horizontal. In this structure, the inclination angle of the window bottom surface of the contact support is restricted, so the sliding action is not large, but the electromagnetic contactor usually has a high switching frequency, and the growth rate of the insulating film until the next contact time is small. Therefore, this structure is adopted for electromagnetic contactors with high voltage / current level, which are less affected by the insulating film.

意する必要があった。However, since the electromagnetic contactor and the electromagnetic relay are usually housed in a control panel and are often operated in a clean environment, the formation of an insulating film is often negligible. Therefore, in these electromagnetic contactors and electromagnetic relays, those in which the bottom surface of the contact support window is not inclined are used.
Therefore, conventionally, depending on the use environment, it is necessary to use either one of the two types of contact support, one having a horizontal bottom surface and one having an inclined bottom surface, and it is necessary to prepare two types of contact support. It was

用をもたせることができない。In the case of an environment in which the operation frequency is low and the formation of an insulating film must be taken into consideration, such as an ordinary electromagnetic relay, in order to maintain the contact reliability of the contact, for example, a movable contact is used. The child is formed as shown in FIGS. 9 and 10 to increase the number of contact points. This structure
The contact base 13 is divided into two on both sides in the longitudinal direction, and movable contacts are fixedly provided on the respective arms, so that contact reliability is remarkably improved as compared with a movable contactor having a conventional structure. However, in this structure, in order to equalize the contact state at the four contact points, the contact base is made of a thin plate material to keep the contact in a state where the arm is sufficiently curved. When the bottom surface of the contact base window is tilted in order to maintain the contact point, more than half the force of the contact spring is applied to one side of the contact base width direction of the spring seat at the center of the contact base longitudinal direction, and the movable contact becomes a fixed contact. The contact base may be cracked in the process in which the contact base is lifted after the contact is started, and the sliding action cannot be provided.

夫を必要とする。As described above, the contact spring is inserted between the contact base side end surface of the contact spring and the contact base by interposing the spring receiver inclined in the width direction of the contact base so that the contact spring can move the movable / fixed contact in the open state. If it is bent in one of the width directions, the end face of the spring will have a restoring force to return to the horizontal end face, the movable contact will contact the fixed contact, and the contact base will contact the bottom surface of the contact support window. When you start to float from above, the inclined spring end surface begins to become horizontal,
Along with this, the movable contact slides on the surface of the fixed contact. In this way, an electrical contact having a sliding action can be obtained only by adding a spring receiver to the electrical contact having no sliding action. Of course, in this case, since the sliding action appears when the contact base is inclined, one surface of one of the two contacts is made convex and the other is made so that the movable contact and the fixed contact can easily slide. It is necessary to devise such that the surface of is a concave surface or a flat surface having a larger curvature than the convex surface, or both are convex surfaces.

きる。When the inclination of the spring end surface by the spring receiver is realized by providing a protrusion or a ridge on the surface of the contact plate side of the spring receiver, an electric contact having no sliding action can be slid without any structural change. It can be diverted to an electrical contact having a working function. Further, even if the inclination of the spring end surface by the spring receiver is realized by providing a protrusion or a ridge on the surface of the contact base on the spring receiving side, it is not necessary to change the structure of the non-consumable component in the non-sliding type electrical contact. Therefore, all parts of the non-sliding type electric contact can be diverted to the sliding type except for the movable contact.

In addition, if protrusions or ridges are provided on both sides in the width direction of the contact block and the protrusions or ridges on one side are inserted into the notch provided on one side edge in the width direction of the contact block, the contacts of the spring receiver will contact. Positioning of the table becomes easy. Even if the end face of the spring is inclined by providing a protrusion or a ridge on the contact base without using a spring receiver, the non-consumable component of the non-sliding type electric contact can be used as it is for the sliding type. be able to.

わずかに越える。When the movable iron core 7a is attracted to the fixed iron core 7b by energizing the electromagnetic coil 7c (FIG. 3), the contact support 5 connected by the pin 14 moves downward and is held in the contact support window 5a. The movable contact 1 that has been moved also moves downward together with the contact support 5 so that the movable contact 1b ((b) of FIG. 1) becomes the fixed contact 2b.
Touch the top surface of. From this contact time point, the movable contactor 1 starts to float from the bottom surface of the window 5a, and the inclined end surface of the spring ((c) in FIG. 1) starts to return horizontally. As a result, the contact base 1a starts to rotate counterclockwise together with the spring receiver 3, and the contact surface of the movable contact 1a ((a) in FIG. 1) slides on the upper surface of the fixed contact 2b. Since this sliding operation actually has inertia in the rotation of the spring receiver 3 of the contact base 1a, the end point of the rotation of the spring end surface slightly exceeds the horizontal state.
