Abstract

As shown in the cross-sectional view of Figure 1b is a cross-shaped c-shaped open in the direction of the centrifugal force of the circle, as shown in Figure 1a is characterized in that the outlet is formed to withdraw the coil end on one side, the fixed pin is formed Form of bobbin.

Description

BOBBIN FOR SHOT COIL 1}

In using the short coil to remove the electromagnetic wave induced in the signal line and flowing into the electronic product, by installing the short coil near the lead terminal of the signal line, the effect of absorbing and removing the electromagnetic wave induced in the line from the short coil is eliminated. You can get it. It relates to a bobbin for making this short coil easy to manufacture and use and easy to handle. In the conventional short coil, as shown in FIG. 2, both ends of the coil end of the short coil are electrically shorted to dissipate the induced electromagnetic current. 2 is a structure in which a wire having excellent conductivity such as copper and the like is closely contacted with a concentric circle and wound several times, and both ends thereof are shorted to be in an electrically connected state. In the case of manufacturing the short coil using only the wire rod as shown in FIG. 2, the shape of the coil may be deformed and the coil may be shortened when the end of the wire is soldered. If the wire is thick, the wire is easily dislodged without deformation, but if the wire is thin, the wire is easily deformed and not easily pulled out. In order to short-circuit, the end of the coil is precipitated in the lead bath and the coating of the coil is peeled off and soldered simultaneously. In addition, there is a problem that the coil is easily deformed or damaged during handling after the short coil is completed, and the storage method is difficult.

It is designed to make the short coil easy and not to be deformed after manufacturing, and to devise a method of preventing the coil from shorting even when soldering the end of the wire and various types of bobbins with fixed pins.

In order to realize this object, the first configuration of the present invention is characterized by having a c-shaped cross section open in the direction of the centrifugal force of the circle as shown in the cross-sectional view of FIG. 1b and drawing the coil end on one side as shown in the perspective view of FIG. It is characterized in that the outlet is formed so that. Figure 1c is a cross-sectional view showing the shape of the wire wound on the bobbin of the present invention. The second configuration is characterized in that the cross-section as shown in the cross-sectional view of Figure 3b is a c-shaped open in the direction of the centrifugal force of the circle and the outlet is formed to draw the coil end on one side as shown in the perspective view of Figure 3a and can fix the bobbin The fixing pin is formed in the horizontal direction so as to form the bobbin surface. The third configuration is characterized in that the cross section is a c-shaped cross section open in the direction of the centrifugal force of the circle as shown in the cross-sectional view of FIG. The outlet is formed to withdraw the end of the coil is characterized in that the fixing pin is formed in a direction perpendicular to the bobbin surface to fix the bobbin. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. As an example, when the coil is wound around the bobbin of 1a, the bobbin is mounted on the jig of the winding machine, and the end of the wire is connected to the inside of the bobbin through the outlet. After winding several times, pull out the end part of wire rod through the outlet and take out the bobbin from the winding machine jig, and the winding is completed. The coil inside the bobbin can be prevented from being soldered. The bobbin of FIG. 1A is manufactured only by the coil function, and is suitable for fabricating a structure that can be used in combination with other components or can be fixed by molding. In the second embodiment, when the coil is wound around the bobbin of 3a, the bobbin is mounted on the jig of the winding machine, the end of the wire is inserted into the bobbin through the outlet, the wire is wound several times, and the end of the wire is pulled out through the outlet. When the bobbin is removed from the winding machine jig, the winding is completed, and by twisting the ends of each wire and depositing only the bobbin surface in the solder bath, soldering only the lead wire and the coil inside the bobbin can be prevented from being soldered. Since the fixing pin is formed in the horizontal direction with the bobbin surface so as to fix the bobbin, it is suitable for mounting the short coil vertically on a circuit board or the like. In the third embodiment, when winding the coil on the bobbin of 4a, the bobbin is mounted on the jig of the winding machine, the end of the wire is inserted into the bobbin through the outlet, and after winding several times, the end of the wire is pulled out through the outlet. When the bobbin is pulled out from the winding machine jig, the winding is completed, and by twisting the ends of each wire and depositing only the bobbin surface in the solder bath, soldering only the lead wire and the coil inside the bobbin can be prevented from being soldered. Since the fixing pin is formed in the direction perpendicular to the bobbin surface so as to fix the bobbin, it is suitable for mounting the short coil horizontally on a circuit board or the like.

By using the bobbin of the present invention, the wire is wound close to the wire, even if the wire is thin wire rod is wound on the bobbin can be easily and safely removed from the winding machine. In addition, in order to shorten both ends of the coil in which the winding is completed in the winding machine, the coil ends are precipitated in the solder bath so that the coating of the coils is peeled off and soldered at the same time. The coil body is not soldered at the same time as the coil tip. In addition, since the coil is protected by bobbins during handling after the short coil is completed, there is no deformation or damage to the coil, and thus it is easy to handle.
