Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a relay also called an electromagnetic relay, and more particularly to a hinge type relay.

[Prior Art] Conventionally, when assembling a hinge-type relay, a bobbin wound with an exciting coil is mounted at a predetermined position of a base, which is a mounting member, and after mounting a yoke, an iron core, a contact terminal, etc., the base is mounted. The terminal of the exciting coil is wound around the coil terminal attached to the base and soldered, or the coil terminal is connected to the terminal of the exciting coil in advance and the bobbin is mounted on the base, and then the terminal of this base is attached. The coil terminal was attached to the attachment hole. In order to ensure insulation between the exciting coil and the magnetic circuit or contact circuit, insulating measures are taken such as winding an insulating tape around the outer circumference of the exciting coil wound around the bobbin or interposing an insulating sheet where necessary. ing.

[Problems to be solved by the invention] However, after the bobbin is mounted on the base, the terminal of the exciting coil is connected to the coil terminal, or the terminal of the exciting coil is pre-connected to the base of the base. The work to attach to the terminal mounting holes had to be done carefully, paying attention to disconnection and short circuit, so the workability was poor. Also, as a measure for insulation, complicated manual work is required when winding a tape around the outer circumference of the exciting coil or providing a sheet at a required position, so in the end, the conventional structure had poor assemblability and automation was difficult. .

The present invention has been made in view of such circumstances, and an object thereof is to provide a relay that is easily assembled.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a coil portion in which a coil terminal, to which a terminal of the exciting coil is connected, is fixed to a part of a bobbin around which the exciting coil is wound, An insulating wall is erected at a predetermined position of the base part, and a contact body is provided outside the insulating wall, a base body, an iron core inserted into a through hole extending in the axial direction of the bobbin, and the iron. A yoke fixed to the core and extending to the outside of the insulating wall; a movable contact contacting and separating from the contact terminal on the free end side; and a leaf spring fixed to the yoke on the base end side; An exciting coil is wound by inserting the coil portion in a direction parallel to the base and having a mounting notch formed in the base portion and cut into a shape corresponding to the fixed portion of the coil terminal. Place the mounted bobbin inside the insulating wall and fix it The bottom of the base body is constituted by the base and the fixed portion by fitting the portion into the mounting notch of the base.

[Operation] According to the above means, the end of the exciting coil is connected to the coil terminal before the coil portion is attached to the base body, the coil portion is inserted into the base body, and the fixed portion of the coil terminal is mounted on the base. If you insert it into the mounting notch of the part, you can obtain a base with an exciting coil and coil terminals, so you can automate this assembly process, and insert the coil inside the insulating wall of the base body. Therefore, complicated work such as winding an insulating tape or interposing an insulating sheet is unnecessary.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 relate to an embodiment of the present invention. FIG. 1 is a horizontal sectional view of a hinge type relay, FIG. 2 is a vertical sectional view of this relay, and FIG. 3 is a bottom view of this relay. is there.

The hinge type relay shown in FIGS. 1 to 3 is roughly divided into a coil portion and a base portion. The coil portion includes an exciting coil 1, a bobbin 2 formed by winding the exciting coil 1 a predetermined number of turns, and a bobbin 2 of the bobbin 2. The coil terminals 3 and 4 are attached to the extending portion, and the winding start end and the winding end end of the exciting coil 1 are connected to the coil terminals 3 and 4, respectively. In addition, the base part has a base body 5 which is a main part of the base by projecting insulating walls 5a and 5b at predetermined positions, and contact terminals 6 and 7 fixed to the base body 5 outside the insulating wall 5a. An iron core 8 inserted into the through hole 2a of the bobbin 2, and a substantially L-shaped yoke 9 fixed to the iron core 8 and extending to the outside of the insulating wall 5b.
And a conductive leaf spring 11 having a movable contact 10 on the free end side and a base end side fixed to the yoke 9, and an armature 12 attached to the leaf spring 11. The movable contact 10 comes into contact with and separates from the contact terminals 6 and 7 in accordance with the movement of.

The hinge type relay configured as described above is assembled by mounting the coil portion on the base portion. That is, the exciting coil 1 is wound around the bobbin 2, and the coil terminal 3,
4 is attached, and the winding start end and the winding end end of the excitation coil 1 are connected to the coil terminals 3 and 4, respectively, so that the coil portion is prepared independently of the base portion, and the coil portion is formed on the base body. 5 is inserted into the insulating walls 5a, 5b from the direction of arrow A in FIG. 1 and fixed. At that time, FIG. 2 and FIG.
The fixed portion of the coil terminal indicated by reference numeral 2b in the drawing is fitted into the mounting notch 5c formed in the base 5 to form the bottom surface of the base 5 main body. Then, on this base 5,
The yoke 9, the iron core 8, the contact terminals 6, 7 and the leaf spring 11 are sequentially incorporated to complete the hinge type relay shown in FIGS.

As described above, in the above embodiment, the terminals of the exciting coil 1 are connected to the coil terminals 3, 4 before the bobbin 2 is mounted on the base 5.
Since the bobbin 2 can be slidably inserted into and fixed to the base body 5, each member can be easily assembled. In addition, the coil part has insulating walls 5a and 5b.
The excitation coil 1 is attached to the inside of the
There is no risk of short-circuiting 6, 7 and the yoke 9 and the like, and when an insulating tape is wound around or an insulating sheet is interposed, troublesome work becomes unnecessary. Therefore, the assembly process of the above embodiment can be automated, and the work efficiency can be dramatically improved.

[Effects of the Invention] As described above, according to the present invention, the coil portion formed by connecting the end of the exciting coil wound around the bobbin to the coil terminal can be handled as a single body, and the coil portion can be used as a base. It is inserted from the side to the main body and positioned inside the insulating wall, and the fixing part is fitted into the mounting notch to form the bottom surface of the base main body, so the assembly of each member is easy, and the tape or sheet There is no need to take complicated insulation measures such as using the above, which enables automatic assembly and greatly improves workability during manufacturing.
