19として画成される。 Generally, many electromagnetic contactors have built-in normally open and normally closed auxiliary switches. FIGS. 1 and 2 show an example of such a conventional electromagnetic contactor. The structure of this electromagnetic contactor will be described approximately in the order of assembly. First, the movable contact support 1 and the movable iron core 2 are connected by a pin 3. A contact spring 4 is attached to the window 1a of the movable contact support 1, an auxiliary normally closed movable contact 5, an auxiliary normally open movable contact 5, 6, and a contact spring 7 are attached to the window 1b, and both auxiliary contacts 5, 6 are attached to the window 1b. Insert the contact spring 7 in between. After inserting the movable part assembled in this way from the bottom (left end in the figure) of the case 9 to which the main fixed contact 8 is attached, the main fixed contact 8 is inserted into the window 1a of the movable contact support 1 protruding to the right side of the case 9. Insert the main movable contactor 10 and contact spring 4 corresponding to the main movable contactor 10 and the contact spring 4. Subsequently, the auxiliary normally closed fixed contact 11 and the auxiliary normally open fixed contact 12 are attached in correspondence with both the auxiliary movable contacts 5 and 6, respectively. The auxiliary normally closed fixed contact 11 may be attached when the main fixed contact 8 is attached, but the auxiliary normally open fixed contact 12 must be attached after the movable contact support 1 is inserted, so it is usually done like this. do. Next, if the base 15 on which the fixed core 14 around which the electromagnetic coil 13 is wound is installed is attached to the bottom of the case 9 with screws 16 so as to cover it, the fixed core 14 corresponds to the movable core 2. Finally, cover 17, which has partition wall 17a inside, is placed over the parts of main contacts 8 and 10 exposed to the right and fixed with screws 18, and the inside of cover 17 is defined as arc extinguishing chamber 19. .

is pressed to the right side of the . Electromagnetic coil 13
When energized, the movable core 2 is attracted to the fixed core 14 against the return spring, moving the movable contact support 1 to close the main contacts 8 and 10 and open both auxiliary normally closed contacts 5 and 11. , both auxiliary normally open contacts 6, 12 close. When the power is turned off, it returns to its original state due to the bias of the return spring.

多い欠点がある。 By the way, the assembly work for this device is mainly done using case 9.
This is done through the opening on the left side of the At this time, since the auxiliary normally-closed fixed contact 11 is attached after the movable part is inserted into the case 9, it is attached opposite the auxiliary normally-open movable contact 6 and the auxiliary normally-closed movable contact 5. Therefore, these auxiliary movable contacts become an obstacle to the assembly work, and sometimes the tip of the auxiliary normally closed fixed contact to be installed may cause the already installed auxiliary movable contact to fall out of the window or tilt. Sometimes. Furthermore, when it becomes necessary to replace the movable iron core, the movable contact support, etc. and the movable part is removed from the case, the auxiliary normally open fixed contact must be removed along with the main movable contact, which has the disadvantage of requiring a large number of man-hours.
本考案は上述の欠点を除去し、組立てと分解が

記組体に装備することにより達せられる。 The purpose of this is to provide an electromagnetic contactor in which an assembly of a movable contact support and a movable iron core is inserted into a box-shaped case with a main fixed contact on the top surface and an opening at the bottom and assembled through the bottom opening. In the case where the auxiliary switch is incorporated into the case, the case is divided into upper and lower halves, an upper case and a lower case that can be connected to and separated from each other, and the normally closed fixed contact of the auxiliary switch is inserted into the upper case. This is achieved by fixing the normally open fixed contacts of the auxiliary switch to the lower case side, respectively, and equipping the assembly with the movable contact of the auxiliary switch.

16により結合してもよい。 Next, the present invention will be explained in detail based on drawings according to embodiments. As shown in FIGS. 3 and 4, the electromagnetic contactor according to the present invention has a case 9 divided into two parts: an upper case 9a that is about the right half, and a lower case 9b that is about the left half that closes the bottom of the left end in the figure. The configuration is exactly the same as the conventional one except that it is divided. This will be explained approximately in accordance with the assembly order. First, the movable contact support 1 and the movable iron core 2 are connected by the pin 3. A contact spring 4 is attached to the window 1a of the movable contact support 1, and an auxiliary normally closed movable contact 5, an auxiliary normally open movable contact 6, and a contact spring 7 are attached to the window 1b. Insert 7 in between. The movable part thus assembled is inserted from the left end of the upper case 9a to which the main fixed contact 8 and the auxiliary normally closed fixed contact 11 are attached. Then, the auxiliary normally closed movable contact 5 comes into contact with the auxiliary normally closed fixed contact 11. Next, the main movable contact 10 corresponding to the main fixed contact 8 and the contact spring 4 are inserted into the window 1a of the movable contact support 1 protruding to the right side of the upper case 9a. Next, attach the auxiliary normally open fixed contact 12 to a predetermined position, and then overlap the right end surface of the lower case 9b, on which the fixed iron core 14 wound with the electromagnetic coil 13 is installed at the bottom, on the left end surface of the upper case 9a. Open fixed contact 1
2 corresponds to the auxiliary normally open movable contact 6, and the fixed core 14 corresponds to the movable core 2. Then, the upper case 9a and the lower case 9b are connected using screws 20. Finally, cover 17, which has partition wall 17a inside, is placed over the parts of main contacts 8 and 10 exposed to the right, and is fixed with screws 18, so that the inside of cover 17 is defined as arc extinguishing chamber 19. . In the structure of the electromagnetic contactor according to the present invention, the auxiliary normally closed movable contact is inserted from the left side of the upper case where the auxiliary normally closed fixed contact is attached, and is attached to the left side of the auxiliary normally closed fixed contact. Further, the auxiliary normally open fixed contact is inserted from the left side of the auxiliary normally open movable contact after the auxiliary normally open movable contact is attached, and is attached to the left side. That is, each of the auxiliary contacts is attached sequentially from the inside of the case to the outside. Therefore, the auxiliary contacts do not interfere with each other during installation. Furthermore, when disassembling the electromagnetic contactor to replace the movable core, movable contact support, etc., the outer auxiliary contacts can be removed in sequence.
Therefore, the auxiliary contacts do not interfere with each other during removal. Also, since each case is shallow, it is easy to assemble parts inside. In the embodiment, the lower case, which is divided into upper and lower halves, has been described as a box having a lower bottom. However, this is made into a cylindrical shape, and a base 15 as shown in the bottom of FIGS. 1 and 2 is attached to the lower end of the lower case. and this base 1
A fixed iron core 14 having an electromagnetic coil 13 wound thereon and a normally open fixed contact 12 of the auxiliary switch may be fixed to the base 15, and the base 15 may be connected to the lower case 9b with screws 16 at the end of assembly.
本考案による電磁接触器の動作は、従来のもの
と全く同様であるから説明は省略する。 The operation of the electromagnetic contactor according to the present invention is exactly the same as that of the conventional one, so a description thereof will be omitted.
