線は不可能であった。(Explanation) Conventional technology Conventionally, this type of chip coil is made by punching out a strip of metal with a die, forming a plurality of terminal pieces toward the center of a rod-shaped frame at regular intervals, and then forming a composite including the tips of the terminal pieces. It was impossible to wire the coils unless the frame was molded with resin to form a heel and a drum core or bobbin was glued to its top surface, and then all the connecting parts of the frame were cut and separated. In other words, winding and wiring are performed by rotating and moving the wire discharge vibrator of the automatic winding machine, so if the connection part of the frame remains, the wire discharge pipe cannot be moved around the terminal and wiring to the terminal is impossible. Met.

FIG. 4 is a side sectional view after assembly. In the figure, reference numeral 1 denotes a band-shaped metal material, which is punched out using a die to form a plurality of windows, thereby forming connecting portions 2 and 2' and a pair of L-shaped portions 3 and 3'.

端子６部分を被覆するため全体を樹脂成形１０を行う。An inverted trapezoidal projection 7 is formed on the outer mIJ of the connecting portion 2' on one side. This is shown in FIG. Next, a base portion 4 made of synthetic resin is shaped to a certain extent in a space including the northward portions of the pair of L-shaped portions 3, 3'. A boppin 5 like a drum core is placed on the upper surface of the base part 4. Next, cut off one end of each L-shaped part 3, 3' that connects to the connecting part 2' on one side, bend it upwards from the base, and then bend it laterally to create a step slightly below the horizontal line. Let's call it terminal 6. Next, to wind the wire on the bobbin 6, the wire discharge vibrator of the automatic winding machine passes through the back side of the inverted trapezoidal protrusion 7, bends toward the bobbin 5, passes over the top surface of the wiring terminal 6, reaches the bobbin 5, and wraps around the bobbin 5. Rotate to perform winding. The end of the winding passes over the top surface of another wiring terminal 6 and goes around the reverse side of the inverted trapezoidal projection 7 again to lead to the next section. 11 is a wire rod, and l2 is a winding portion. These are shown in FIG. 2 as a top view A and a side view B. After winding the wire one after another in this way,
The wire on the upper surface of the wiring terminal 6 is spot welded 8 or soldered onto the upper surface of the wiring terminal 6. After this, the connecting portion 3 including the surplus portion of the wiring terminal 6 and the portion of the inverted trapezoidal protrusion 7
After cutting out the parts, the entire body is molded with resin 10 to cover the base portion 4, bobbin 5, and wiring terminal 6 portions.

At this time, most of the other end of the L-shaped part 3 is exposed from the coating resin as an external terminal 9, and the connecting part 2, etc. is cut off (the dotted line in Fig. 3 indicates the cut-off part) to form individual coils. This external terminal 9 is bent along the outer periphery of the coating resin 10 and placed on the side and bottom surfaces to form an external connection terminal. This is the fourth
Shown in side sectional view in the figure.

る。(e) Functions and Effects Since the present invention employs such a manufacturing method, the base portion on which the bobbin is placed does not come apart individually, which would cause inconvenience in the subsequent process, as in the conventional work process. Particularly in the manufacturing process of ultra-small inductors, the disadvantage of being extremely difficult to handle because individual parts cannot be picked up with one's fingers has been solved, and the present invention has the advantage that it is possible to work on multiple parts simultaneously at the same time. There is something very big about it.
