Description

[Detailed Description of the Invention] The present invention relates to an insert molded product in which a plurality of wires are fixed in parallel and an electric wire is wound and connected around each wire.

Conventionally, when winding and connecting an electric wire around each wire of an insert molded product in which multiple wires with circular cross sections are fixed so that their axes are parallel, an insulator is used as shown in Figures 1 to 3. A plurality of notches 1 inclined by θ with respect to the axis of the wire 6 are formed on a wire 6 fixed to a wire 5 (for example, synthetic resin, etc.), and an insert molded product 3 is formed so that an electric wire 9 is wound around the notch 1. .

The notch 1 is formed to prevent the electric wire 9 wound around the wire 6 from coming off the wire 6. Usually, after the plurality of wires 6 are fixed with the insulator 5,
A notch 1 is formed in the wire 6 by pressing or the like.

For this reason, when the notch 1 is processed, the wire 6 is bent near its base, as shown in FIG. 4.

Note that this bending occurs for the following reasons.

In other words, when multiple notches are inserted into the wire, the notched portion of the mold receives lateral force from the adjacent notches and at the same time restrains the force that tends to bend the wire. Although the wire does not bend, since there are no adjacent notched portions at the first and last notched portions, the notched portions of the wire cannot be restrained by the mold, and the wire is deformed and bent.

Therefore, in the example shown in FIG. 4, bending occurs near the base of the wire 6.

Now, when the wire 6 of the insert molded product 3 with such bending is to be assembled into a hole drilled in the product, it takes a lot of time to assemble it due to variations in the deviation B of the tip of the wire 6. .

In addition, when the above insert molded products 3 are combined back to back and used as an integral unit, the deviation B of the tip of the wire 6 is 2.
It has the disadvantage that it is difficult to incorporate because it is twice the size.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide an insert molded product that eliminates the displacement of the wire tip caused by the bending of the wire due to notching.

In order to achieve the above object distantly, in the present invention, one or several notches formed at the position closest to the fixed part of the wire are inclined in a direction different from the other notches with respect to the axis of the wire, Prevents wire bending.

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

FIG. 5 shows an embodiment of the present invention. In the figure, 7 is a notch, and a notch is placed at a position closest to the fixed part of the wire 6 fixed to the insulator 5, relative to the axis of the wire 6. It is formed to be inclined at an angle α in a direction different from the notch 1.

In the above configuration, the misalignment of the tip of the wire 6
Connect the notch 7 closest to the fixed part to the other notch 1 and the wire 6.
This problem was solved by forming the structure so that it is inclined by α in a different direction with respect to the axis of the plane.

The depth and number of notches 7 can be adjusted by adjusting the material of the wire 6, the depth and number of notches 1, etc. in order to eliminate the misalignment of the tip of the wire 6 bent by the processing of the notches 1. It is possible to control the misalignment of the tip.

As described above, according to the present invention, one or more notches closest to the fixed part of the wire are formed to be inclined in a direction different from the other notches with respect to the axis of the wire. It is possible to eliminate misalignment of the wire tip caused by bending of the wire due to insertion.

Furthermore, it is possible to eliminate misalignment of the tip of the wire, making it easier to incorporate it into a product.

Claims (1)

[Scope of utility model registration request] A plurality of wires are arranged and fixed on an insulator at predetermined intervals so that the axes of the wires are parallel to each other, and each wire has a plurality of first notches inclined in the same direction at a predetermined angle with respect to the axes of the wires. In the insert molded product, in which an electric wire is wound and connected to the notch forming portion of the wire, at least one second notch is formed in the first notch with respect to the axis of the wire.
The notch is inclined in a direction different from the direction of the first notch, and is formed at the root of the wire near the insulator so as not to overlap with the first notch, thereby correcting misalignment of the tip of the wire. Insert molded products.
