Abstract

PURPOSE:To provide a winding jig where appropriate force is exerted constantly on a winding material when winding a wire on a toroidal core. CONSTITUTION:A hook bar 1, whose top is hook-shaped, is set in the recess 6 opened in the top edge of a bar 3 fitted with a lever, and at the section where it is set, a ball plunger 4 is buried from the side of the bar 3 fitted with lever, and the force of suppressing the hook bar 1 with the ball plunger 4 is adjusted so that it may come off the bar 3 fitted with lever in case that excessive force falls on the hook bar 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding jig for a toroidal coil.

[0002]

2. Description of the Related Art Conventionally, a toroidal coil winding jig of this type has been constituted only by a rod having a hook-shaped tip at one end, as shown by a hook rod 1 in FIG. Therefore, when winding the toroidal core 9, the winding force is determined by the pulling force of the winding person, and it is difficult to always work with a constant force.
Since the toroidal coil winding material 5 uses a copper wire with a film, if the winding force is too strong, the film will break and insulation will be defective.

[0003]

When winding a toroidal coil, an appropriate and constant force is applied during winding so that the winding material 5 is not excessively applied with force and the film of the winding material 5 is not damaged. Adjustable.

[0004]

According to the present invention, in order to eliminate these drawbacks, FIG. 1 (a) shows a conventional hook bar 1 having a recessed hole 6 [FIG. b)] is inserted into the handle bar 3 and is pressed by the ball plunger 4. When the winding force is excessively applied, as shown in FIG. The hook rod 1 is disengaged from the handle rod 3 against the pressing force of the plunger 4, and the operator is made aware that excessive force is applied, so that the occurrence of insulation failure due to film breakage of the winding wire can be prevented. It is possible. That is, according to the present invention, a through hole (7) reaching the concave hole (6) from the outside of a bar (1) having a hook-shaped tip at one end and a shaft (3) having a concave hole (6) on the end surface. And a hook rod (1) inserted into the recessed hole (6) is pressed and fixed by a ball plunger (4) mounted in the through hole (7), toroidal coil winding. A toroidal coil winding jig, characterized in that the hook rod (1) according to claim 1 is provided with a recess (8) for receiving the tip of the ball plunger (4). The toroidal coil winding jig according to 1, wherein the adapter (2) is interposed between the hook bar (1) and the handle bar (3). A recess for receiving the tip of the ball plunger (4) in the adapter (2) according to claim 1. (8) is a toroidal coil winding jig, wherein a provided.

[0005]

The toroidal coil winding jig, which is conventionally only the hook rod 1, is combined with the rod with handle 3, and the force applied to the winding is adjusted by adjusting the pressing force of the ball plunger. It was possible to adjust.

[0006]

EXAMPLE This example will be described with reference to the drawings.

[0007]

[Embodiment 1] As shown in FIG. 1, one end of a toroidal coil winding jig (hook bar) 1 which has been conventionally used is inserted into a recessed hole 6 formed in an upper end surface of a bar 3 with a handle, The ball plunger 4 is attached to the through hole 7 that reaches the recessed hole 6 from the outer surface of the handle rod 3, and the portion of the hook rod 1 inserted into the handle rod 3 is pressed and fixed. When winding is performed using the toroidal coil winding jig composed of the hook rod 1 and the rod with handle 3, when the winding force is excessively applied, as shown in FIG. Is removed from the bar 3 with a handle, so that it is possible to prevent excessive winding force. Further, in order to adjust the force of the winding, the force of pushing the hook rod 1 of the ball plunger 4 can be adjusted by the insertion depth of the ball plunger 4 into the through hole 7.

[0008]

[Embodiment 2] As shown in FIG. 2, one end of the hook rod 1 which is not hooked is inserted into a hook rod receiver (adapter) 2 and fixed with a screw. The adapter 2 is inserted into the recess formed in the upper end surface of the bar 3 with a handle. The ball plunger 4 is attached to the through hole 7 that reaches the recessed hole 6 from the outer surface of the handle rod 3, and the inserted portion of the adapter 2 inserted into the handle rod 3 is pressed,
Fix it. When winding is performed using the toroidal coil winding jig including the hook rod 1, the handle rod 3, and the adapter 2,
When the winding is applied excessively, as shown in FIG. 2B, the adapter 2 comes out of the bar 3 with the handle and the hook rod 1 inserted, so that it is possible to prevent an excessive winding force. or,
In order to adjust the force of the winding, the force of pushing the adapter 2 of the ball plunger 4 can be adjusted by the insertion depth of the ball plunger 4 into the through hole 7. It should be noted that the hook rod 1 of FIG. 1 shows an example in which a recess 8 for receiving the tip of the ball plunger 4 is not provided in a portion where the tip of the ball plunger 4 comes into contact with and presses. The recess 8 may be provided so that the winding force can be easily adjusted depending on the type and winding method. On the other hand, the adapter 2 for receiving the hook rod 1 shown in FIG. 2 is provided with a concave portion 8 for receiving the tip of the ball plunger 4, but the concave portion 8 is formed by the winding force or due to processing. It may not be possible.

[0009]

As described above, according to the present invention, a winding jig which has a simple structure and can be manufactured at low cost can be used even by a beginner to perform winding without causing the insulation failure due to the tear of the coating of the copper wire. It is possible to manufacture a highly reliable toroidal coil.

[Brief description of drawings]

FIG. 1 is a front view of an embodiment of the present invention. FIG. 1 (a) is a view showing a state in which the bar 1 is inserted into the bar 3 with a handle and is fixed by the ball plunger 4, and FIG. 1 (b) shows that the bar 1 has a force of winding from the bar 3 with a handle. The figure which shows the state which came out too much and got out.
