Abstract

PURPOSE:To easily assemble a hinge type relay without plastically deforming a hinge spring when incorporating an armature and stabilizing action characteristics by providing a guide edge section for guiding the incorporation on the window hole of the armature inserted with the hinge spring into the window hole of the armature. CONSTITUTION:A guide edge section 16 is provided on the window hole 15 of an armature 4. The armature 4 is made of a nearly L-shaped magnetic metal body, a middle bent portion is made a hinge section 4b, and a tail section 4a is arranged nearly in parallel with an iron core 7. When the guide edge section 16 is formed, the armature 4 itself serves as a guide and can be easily and smoothly incorporated while a hinge spring 5 is not deformed largely by another pressing means, the hinge spring 5 is not plastically deformed at all, the automatic assembling workability is improved, a proper hinge support pressing force can be secured, and the action stability can be obtained.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to hinged relays.

[Conventional technology]

Conventionally, as shown in FIG. 6, this type of hinge type relay has an electromagnet and a switch block C arranged side by side in a housing a, an armature e having a window hole d in its tail, and a yoke f. It is swingably supported by an integrally attached hinge spring g.

The hinge spring g is inserted through a window hole d of the armature e.

When incorporating this hinge type relay amateur e,
This can be done manually or with an automatic machine, but in order to reliably incorporate the armature e, the free end of the hinge spring g is widened by the pin h in the direction away from the yoke f as shown in FIG. Yoke f and hinge spring g
need to be inserted between.

[Problem to be solved by the invention]

In the hinge type relay described in the conventional example, the armature e is swingably supported on the yoke f with the hinge spring g inserted through the window hole d of the armature e, so external vibrations and shocks are applied to the left and right sides. This also has the advantage of not causing amateurs to miss or float.

However, this hinge type relay greatly deforms the hinge spring g when installing the armature e, so
The present invention focuses on the above-mentioned problems, where plastic deformation is likely to occur, the pressing force of the armature e is small and insufficient, and the armature e is likely to shift and malfunction. The purpose is to create a hinge-type relay that can be easily assembled without plastically deforming the hinge spring when assembling the armature, and has stable operating characteristics that can stably support the armature. It is on offer.

[Means to solve the problem]

In the hinge type relay according to claim (1), a guide edge portion is provided in the window hole of the armature.

In the hinge type relay according to claim (2), the tip of the hinge spring is bent and the armature is supported at two locations.

[Function] The hinge type relay according to claim (1) has a guide edge portion provided in the window hole of the armature, so that when the armature is disposed between the hinge spring and the yoke end, the hinge spring can be easily deformed. The hinge spring can be easily inserted into the armature window hole.

In the hinge type relay according to claim (2), the tip of the hinge spring presses and supports the armature at two positions on both sides of the yoke support point, so that the armature can be stably supported without shifting.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in FIG. 1, the hinge type relay of the present invention includes a housing 1, an electromagnet 2, a switch block 3, an armature 4
The housing 1 is composed of a main body base 1a and a cover 1b.

The electromagnet 2 includes an abbreviated yoke 6 made of a magnetic material,
It consists of an iron core 7 made of a magnetic material, one end of which is connected to one end of the yoke 6, and a coil frame 9 made of a molded material such as synthetic resin, with a coil 8 wound around its outer periphery and the iron core 7 inserted inside. It is configured.

10 is a coil terminal, and 11.12 is a connection terminal.

The switch block 3 includes a movable contact 13 and a fixed contact (not shown), and the movable contact 13 is actuated by a tail portion 4a of an armature 4 (described later) via a card 14.

As shown in FIGS. 1 and 3, the armature 4 is made of an abbreviated magnetic metal body, and the intermediate bent portion is a hinge portion 4.
b, and the tail portion 4a is arranged substantially parallel to the iron core 7.

This tail portion 4a is provided with a window hole 15 for inserting a hinge spring, and a wedge-shaped guide edge portion 16 is formed at the side edge of the hinge portion 4b of the window hole 15.

The hinge spring 5 is formed by bending one end (free end) of a metal strip plate, and its base end is fixed to the outer surface of the yoke 6, and the tip 5a of the free end is opposite to the yoke 6. The armature 4 is curved toward the window hole 15 so that the armature 4 can be easily inserted into the window hole 15.

As shown in FIG. 4, when assembling the armature 4 into the electromagnet 2, insert the tip 5a of the hinge spring 5 into the window hole 15 of the armature 4, position it, and then connect the free end of the hinge spring 5 with the yoke 6. The guide edge portion 16 of the window hole 15 is pushed between the tips of the window hole 15.

At this time, the hinge spring 5 is deformed to the side opposite to the yoke 6 by an amount equal to the thickness of the armature 4, but only a moderate pressing force is applied to the armature, and there is no risk of deformation.

Note that since the operation of the relay is the same as that of the conventional example, a description thereof will be omitted.

FIG. 5 shows the main parts of the second embodiment of the present invention, and the difference from the first embodiment is that the tip 5a of the free end of the hinge spring 5 is
is bent to the yoke 6 side, and then curved so that a cylindrical surface is formed on the side opposite to the yoke 6, and at two places 4c and 4d of the shoulder part of the hinge part 4b of the armature 4. This is the point where the hinge spring 5 is brought into contact.

According to this embodiment, when assembling the armature 4, the curved tip portion 5a of the hinge spring 5 smoothly guides the guide edge portion 16 of the armature 4, and the armature 4 can be easily assembled. Since the hinge spring 5 presses the two positions 4c and 4d of the shoulder part of the part 4b,
The support of the amateur 4 can be made more stable compared to support at one location d.

FIG. 8 shows an example of the marking method on the housing 1, and the markings (trademark, country of manufacture, UL rating, standards, etc.) on the outer surface of the housing 1 of the relay are not limited to the - side. (For example, the trademark T, country of manufacture name N, and UL rating can be provided on the top surface, and the standard S such as C3A, TUV, VDE, etc. can be provided on the side surface, which is convenient for solving the lack of printing space and reducing the size of the relay.) It is.

Furthermore, as shown in Fig. 9, when two sides are not required for stamping, for example, when the stamping surface is large and a composite stamp can be stamped on one side, the trademark T and the name of the country of manufacture N are made common, and the center line L
The UL rating may be stamped on the left side, and the C3A standard S, etc. may be stamped on the right side.

〔Effect of the invention〕

The hinge type relay according to claim (1) has a guide edge portion for guiding the assembly formed in the window hole of the armature, so that the hinge spring can be prevented from being significantly deformed by other pressing means when the armature is assembled as in the past. , the amateur can act as a guide and assemble it easily and smoothly, there is no risk of plastic deformation of the hinge spring, and not only improves automatic assembly workability, but also ensures appropriate hinge support pressure force and improves operation. Stability can be achieved.

In the hinge type relay according to claim (2), since the tip of the hinge spring supports the armature hinge part at two places, the stability of swinging support of the hinge part can be ensured, and stable operating characteristics can be obtained. be able to.
