In the case of the above-mentioned conventional technique, the terminal formed by punching out the metal frame plate is required to have a length including the portion to be taped. Further connecting frame parts are required. Therefore, the width of the metal frame plate forming these terminals has been relatively wide. Moreover,
The frame portion connecting the terminals became unnecessary after taping and was discarded, resulting in waste of the frame material.

Further, in the punching work of the metal frame plate, if the terminals are long, the rigidity of the terminal row after punching becomes weak, and the terminal row vibrates due to the operation of the punching punch, and the punching rotation speed cannot be increased. There was also a problem.

The present invention has been made in view of the above problems of the prior art, and provides a taping electronic component and a manufacturing method thereof in which the waste of the metal frame plate can be reduced and the punching efficiency can be increased. The purpose is to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The taping electronic component of this embodiment is
As shown in FIGS. 1 and 2, this is a so-called vertical variable resistor 1. In this variable resistor 1, a resistor (not shown) is provided on an insulating substrate 2 made of ceramics or the like, and a slider (not shown) is slidably mounted on the resistor. An adjusting knob 4 that holds the slider is provided so as to rotate integrally with the slider. The knob 4 is formed with a slot 6 for rotation with a driver or the like. Electrodes 8 are formed on both ends of the resistor, and the electrodes 8 are connected to the mounting portions 14 and 16 of the pair of terminals 10 and 12 of the variable resistor 1. The mounting portions 14 and 16 sandwich the edge of the substrate 2 and are in contact with the electrode 8, and are further fixed by soldering together with the electrode 8. Further, on the back side of the insulating substrate 2, a middle terminal 17 is provided so as to project.

Each of the terminals 10 and 12 is, as shown in FIG.
It is formed by punching out a metal frame plate, and is integrally projected on the upper edge of the frame portion 18 at one side edge of the metal frame plate. The terminal 10 located on the left side of FIG. 3 and the terminal 12 located on the right side are paired,
A bridge portion 19 formed by punching out a metal frame plate is integrally provided at the center of each of the terminals 10 and 12. Further, each of the terminals 10 and 12 is provided with a rib 20 convexly formed on the surface side between the bridge portion 19 and the mounting portions 14 and 16. The frame portion 18 has elongated holes 2 on both sides of the extended portion of the terminals 10 and 12, respectively.
1, 22 are provided, and a through hole 24 for positioning is formed between the pair of elongated holes 21 inside the terminals 10, 12.

In the method of assembling a taping electronic component of this embodiment, first, a metal frame plate (not shown) is punched out, and the mounting portions 14, 16 and the like are press-molded to form a terminal row 30 as shown in FIG. . After that, the substrate 2 of the variable resistor 1 is attached and soldered to the attachment portions 14 and 16 of the terminal row 30. Then, when taping is performed, the frame portion 18 is cut by a cutter or the like along the longitudinal direction of the terminals 10 and 12 at a position near the terminals 10 and 12 of the long holes 21 and 22 of the frame portion 18.

By this, a pair of terminals 1 separated from each other
As shown in FIGS. 1 and 2, rectangular frame pieces 26 are formed and left at the tips of 0 and 12. Then, in each variable resistor 1, the tip portions of the terminals 10 and 12 and each frame section 26 of the terminal tip portion of the variable resistor 1 are fixed on the automatic feeding tape 28 by the adhesive tape 30 at regular intervals. Can be installed with. And this automatic feeding tape 2
8 is placed in the feeding part of the automatic assembly machine in a state of being wound into a roll or folded into a zigzag shape,
The variable resistor 1 is attached to a circuit board on which various electronic components are attached.

In mounting the variable resistor by the automatic assembly machine, first, the terminals 10 and 12 are cut at the upper portion of the portion where the rib 20 is formed, and the variable resistor 1 is separated from the automatic feeding tape 20. Then, with the machine hand of the automatic assembly machine, the variable resistor 1 is gripped, the terminals 10 and 12 and the middle terminal 17 are inserted into the terminal insertion holes of the circuit board, and the terminal 1
The mounting is completed by cutting the portion where 0 and 12 are excessively protruding from the back surface of the circuit board.

According to the variable resistor of this embodiment, since the frame portion 18 is used as the taping portion,
The length of the terminals 10 and 12 can be shortened, the amount of the frame plate used can be reduced, and the cost can be reduced. Furthermore, since the terminals 10 and 12 are short and the bridge portion 19 is formed, the rigidity of the terminal row 30 at the time of punching is relatively high, the shake due to punching is small, and the punching rotation speed can be set high.

The electronic component of the present invention is not limited to the variable resistor, but can be used for various electronic components such as switches and capacitors to which terminals are attached.

[0016]

The electronic component of the present invention is cut out so that the frame piece remains integrally at the tip of the terminal and is used as the taping portion. Therefore, the terminal punched out from the metal frame plate is less than the conventional one. It is short. Therefore, the width of the metal frame plate may be relatively narrow, so that the waste of the frame material can be saved and the resource can be saved. Further, vibration of the terminal portion is unlikely to occur during punching, and punching efficiency can be improved.

Further, by bridging the bridge part between the central parts of the pair of terminals, in the step of punching the terminal from the metal frame plate, the vibration of the terminal portion at the time of punching is suppressed, and the punching rotation speed can be further increased. Even after punching, the terminal is prevented from being bent or twisted.
