Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for winding and wiring a high-frequency coil using a split-wound hollow bobbin having a terminal plate portion with a plurality of terminal pins embedded therein and a plurality of winding grooves. be.

Traditionally, when a bobbin with multiple flanges and multiple winding grooves is installed on the rotating shaft of a winding machine, and the bobbin is rotated to wind the wire, the winding and wiring must be done manually. I had to do it.
In other words, this kind of winding groove is usually narrow, about twice the width of the wire diameter or less, so it takes a skilled worker to guide the wire to a desired winding groove or to move from one winding groove to the next. If the wire is not dexterously handled by a worker, the wire often comes off from the desired winding groove, and it is extremely difficult to have a machine automatically perform these tasks.

The present invention provides a bobbin structure and method that make this possible. This will be explained according to the drawings. FIG. 1 is a perspective view showing the gist of the present invention, and FIG. 2 is a cross-sectional view of its main parts. In the figure, 1 is a terminal plate portion, 2 is a terminal pin planted on the bottom surface, and 3 is a cut groove for wiring provided on the side surface thereof. Reference numeral 4 denotes a hollow bobbin portion of divided winding, which is provided with a plurality of flanges 5 and thereby has a large number of winding grooves 6. Further, a notch 7 is provided on the outer periphery of the collar 5 for guiding the conductive wire to the terminal plate portion 1, and protrusions 8 are formed at both ends of the notch 7. The bobbin part 4, in which these parts are molded as one body, is made of thermoplastic resin, and its protrusions 8
is a slender prismatic or cylindrical piece with dimensions that make it relatively elastic. A hollow portion of the bobbin portion 4 having such a structure is installed on a rotating shaft (not shown) of a winding machine. 9 is the winding wire material and 10
is a nozzle that leads out the wire and guides the winding. Next, the winding and wiring method of the present invention will be explained. First, the nozzle 10 from which the wire 9 is drawn out is placed in a horizontal position, and the terminal pin 2 is rotated around the terminal pin 2.
Wire the wires. Next, the nozzle 10 is placed in a vertical position and moved along the wiring groove 3, passing through the notch 7 of the bobbin portion 4 and leading to the position of the prescribed winding groove 6. Next, the nozzle 10 approaches the bobbin portion 4, turns at a right angle, faces in a direction parallel to the winding groove 6, and is forcibly inserted between the protrusions 8 on both sides to make them expand. This situation is illustrated in FIG. At this time, the protrusion 8 serves as a guide for the wire 9 and is guided accurately into the winding groove 6 without slipping off the collar 5. Next, the nozzle 10 stops at a position slightly away from the bobbin portion 4 during winding, and the rotating shaft immediately begins to rotate to perform winding. In addition, when winding the wire in the next winding groove 6, the rotating shaft must be stopped once and the nozzle 1
0 approaches the bobbin part 4 at the position of the notch 7, moves to the next winding groove 6 while expanding the protrusion 8 of the collar 5, and moves away laterally to introduce the wire 9 into the winding groove 6.
Rotate the rotating shaft again and continue winding. Similarly, when pulling out the tap at the end of winding or in the middle of winding, the nozzle 10 is guided to the terminal plate part 1 while expanding the protrusion 8 while the rotating shaft is stopped, and goes around the terminal pin 2 to complete the wiring. I do. Finally, when all of the above-mentioned operations are completed, the protrusion 8 completes its role as a guide, so that it can be cut from near the root or crushed by heat melting, thereby eliminating any hindrance to subsequent work steps.

As described above, according to the present invention, even if a split winding bobbin with a narrow winding groove is used, the wire can be accurately introduced into the winding groove, and through mechanization, the efficiency of productivity can be significantly increased. , the effects of the present invention are significant.

Claims (1)

[Claims] 1 A hollow made of insulating resin, which has a terminal plate part 1 having a plurality of implanted terminal pins 2 and a wiring groove 3 on the side surface, and has a plurality of winding grooves 6 formed by a plurality of flanges 5. In the bobbin part 4, a notch 7 is provided on the outer periphery of the collar 5, and protrusions 8 are formed on both ends facing the notch 7, and this hollow bobbin part 4 is installed on the rotating shaft of a winding machine, After drawing out the wire 9 of the winding wire and passing the nozzle 10 for guiding the winding wire around the terminal pin 2 and connecting it to the terminal pin 2, the tip of the nozzle 10 moves along the wiring groove 3,
Pass through the notch 7 of the bobbin part 4 and guide the nozzle 10 to the specified winding groove 6 position, bring the nozzle 10 close to the bobbin 4, and forcefully expand between the protrusions 8 of the collar 5 while parallel to the winding groove 6. After moving and introducing the wire 9 into the winding groove 6 and separating the tip of the nozzle 10 from the bobbin part 4, the rotating shaft is rotated to wind the wire, and when transferring the winding to the adjacent winding groove 6. stops the rotating shaft, brings the nozzle 10 closer to the bobbin part 4 again, expands the protrusion 8 at the position of the notch 7, moves to the adjacent winding groove 6, and then moves away laterally to accurately wind the wire 9. The wire is dropped into the groove 6 and the rotating shaft is rotated again to continue winding. At the end of the winding, do the same thing as above, while the rotating shaft is stopped, expand the protrusion 8, guide it accurately into the notch 7, reach the terminal plate part 1, and wire the terminal pin 2 in the same way as above. 8 is a coil winding wire characterized in that the wire rod 9 is prevented from slipping out of the winding groove when moving the winding groove, and is prevented from being introduced into or out of the winding groove during terminal wiring, and winding and wiring can be performed accurately by an automatic machine. , how to wire.
