Description

[Detailed Description of the Invention] The present invention relates to a polarized relay having a contact portion for remote control.

As shown in FIG. 3, in the conventional relay of this kind, the main circuit opening/closing contact part A and the remote control contact part B were arranged on both sides of the armature 4, so both the contact parts A, B
Although it is possible to provide a sufficient insulation distance between the armatures, there is a drawback that the number of main circuits is limited because the main circuit contact section A can only be provided on one side of the armature.

Furthermore, the conventional example shown in FIG. 3 has the disadvantage that the diodes 14a and 14b used in the operating circuit cannot be fixed.

The present invention was developed in view of the above points, so the main circuit opening/closing contacts are provided on both sides of the armature to create a multi-contact configuration.
The purpose of this is to provide a partition wall between the adjacent main circuit switching contact section and the remote control contact section to ensure insulation distance, and to use the partition wall to form a storage space for the diode. .

The present invention will be described in detail below with reference to the drawings. In Figs. 1 and 2, the central part of two parallel magnetic plates 1 and 2 is magnetized in a direction perpendicular to both magnetic plates 1 and 2. The center part of an armature 4 bridged by a permanent magnet 3 is rotatably supported, and both end pieces a and 6b of a U-shaped yoke 6, which has an excitation coil 5 wound around the center part, are connected to both end parts of the armature. The main circuit opening/closing contact part A protrudes between both magnetic plates 1 and 2 and is arranged by the armature 4 on both sides of the armature.
A2 is driven to open/close, and one main circuit open/close contact part A
A remote control contact part B is provided on the outside of the case 10, and includes a contact spring 7 having a fixed central part 7a, and fixed contact terminals 8 and 9 facing each other at both ends of the contact spring 7. The case 10 is
Recesses 12 are formed in two corners of the remote control contact portion B to separate both ends of the remote control contact portion B, and diodes 14a and 1 are installed in the narrowed portions 13 formed in the deep portions of each recess 12.
The opposite poles of both diodes 14a and 14b are connected to the corresponding fixed contacts 8 and 9 of the remote control contact section, and the other pole of each diode 14 is connected to the same end of the excitation coil 5. The other end of the excitation coil 5 and the central fixed portion 7a of the remote control contact spring 7 are respectively connected to remote control input terminals 15 and 16.

17 is a molded body that holds the amateur block together;
It is pivotally supported at the center by a shaft 18, and card portions 19 and 20 for driving the main circuit contacts are integrally provided in a protruding manner.

21 is a card section for driving operation contacts, 23 is a base, 24
is a groove for inserting a diode.

Now in FIG. 2, when the remote control switch 22 is reversed to side a, current flows through the forward direction diode 14a to the exciting coil 5, and by reversing the armature 4, the contacts A□, A2 are turned on. At the same time as closing, contact portion B is reversed to open contact 8 and close contact 9.

Therefore, the excitation current flowing through the excitation coil 5 is instantaneously interrupted by the diode 14b in the opposite direction, and the armature 4 is attracted and held by the permanent magnet 3.

Next, when the remote control switch 22 is reversed to the b side, an excitation current flows instantaneously in the same way as above, reversing the armature 4, and contact A1. Open A2.

In this way, the bistable polarized relay is remotely controlled.

The present invention is constructed as described above, and includes the main circuit switching contact portion A1. A2 is provided on both sides of the armature 4, and the remote control contact part B is provided on the outside of one main circuit opening/closing contact part A□, so the number of main circuits to be controlled can be increased. 11, the main circuit opening/closing contact part A
1 and the remote control contact part B, and each recess 12 formed by the partition wall 11
Since the storage space for the diodes 14a and 14b is provided in the narrow part 13 at the back of the housing, there is an advantage that the diodes can be inserted and fixed.
