Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a series of electronic components.
The present invention relates to a series of electronic components in which electronic components such as electric double layer capacitors of the same direction with leads are accommodated in a carrier tape.

[Conventional technology]

For example, a large number of electronic components are delivered to customers as a series of electronic components using a carrier tape in order to improve the compatibility with a component mounting automatic machine for a circuit board or the like. FIGS. 3 and 4 show a conventional example in which the electric double layer capacitor 1 of the same lead type is connected to electronic components by a carrier tape 5. First, the structure of the electric double layer capacitor 1 will be schematically described. The capacitor 1 includes a capacitor body 2 in which, for example, a plurality of coin-shaped cells are stacked, and a heat-shrinkable insulating sleeve is placed around the cells. I have. Lead terminals 3a and 3b are attached to the anode surface and the cathode surface of the capacitor body 2 by, for example, welding. In this example, since the capacitor body 2 is mounted laterally on a circuit board (not shown), that is, mounted so that its electrode surface is parallel to the circuit board, both lead terminals 3a and 3
b are bent substantially in an L-shape so as to face in the same direction.

The carrier tape 5 includes the electric double layer capacitor 1 described above.
A large number of component storage recesses 6 are formed at predetermined intervals. In this case, a bottom surface 6a corresponding to the capacitor main body 2 and an annular lead storage groove 6b formed concentrically deeper than the bottom surface 6a are provided around the bottom surface 6a corresponding to the capacitor main body 2 in the component housing concave portion 6.

The capacitor body 2 is accommodated in each of the component accommodating recesses 6 of the carrier tape 5 such that the lead terminals 3a and 3b thereof enter the lead accommodating grooves 6b, and the opening of the component accommodating recess 6 is sealed with a cover tape 7. By stopping the operation, the electric double layer capacitor 1 is connected to electronic components. The cover tape 7 is, for example, heat-fusible, and is easily peeled off from the carrier tape 5 at the time of component collection. Further, feed pitch holes 5a and 5b are formed in the flanges at both ends of the carrier tape 5.

[Problems to be solved by the invention]

By the way, when the electric double-layer capacitor 1 is housed in each of the component housing recesses 6 of the carrier tape 5 to form a series of electronic components as described above, the capacitors are usually housed so that their polarities are aligned. The electric double layer capacitor 1 rotates due to the vibration or shock of the electric field, and in extreme cases, the positions of the lead terminals 3a and 3b may be reversed from the initial state. Further, once the series of electronic components is connected, unless the electric double layer capacitor 1 is taken out from the component storage recess 6, it is not possible to perform a characteristic test on its capacitance, loss tangent, leakage current, and the like. There were drawbacks.

[Means for solving the problem]

In order to solve the above problems, according to the present invention, an electronic component having a pair of lead terminals oriented substantially parallel to each other in the same direction in a component storage recess formed on a carrier tape at a predetermined interval is provided. In a series of electronic components in which the leads are accommodated in the recess so that the leads face the bottom of the recess, and the opening of the recess is sealed with a cover tape, the electronic component body is located in the recess. An electronic component having a corresponding bottom surface, an annular lead storage groove formed concentrically deeper than the bottom surface around the bottom surface, and a pair of lead insertion holes formed in the groove bottom of the lead storage groove; Of the pair of lead terminals in the lead storage groove,
And it is set as the structure pulled out from a pair of lead insertion holes.

[Operation] When the lead terminal is inserted into the lead insertion hole, the lead terminal serves as a stopper to prevent rotation of the capacitor body. Therefore, the polarity is not disturbed even if it is subjected to vibration or impact during transport. Further, since a probe or the like of an inspection device can be contacted with the lead terminal from the outside through the lead insertion hole, it is possible to inspect the characteristics and the like while the electronic component is stored in the carrier tape.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 and FIG. In these figures,
The same reference numerals are given to portions which are the same as or can be regarded as the same as those of the conventional example described above.

Referring to FIGS. 1 and 2, in the component storage recess 6, as described in the description related to FIG.
A bottom surface 6a corresponding to the capacitor body 2 and an annular lead storage groove 6b formed concentrically deeper than the bottom surface 6a are provided around the bottom surface 6a, and a lead terminal 3a is provided at the bottom of the lead storage groove 6b. , 3b are penetrated. That is, the tips of the lead terminals 3a, 3b are pulled out from the lead insertion holes 10, 10, thereby preventing the rotation of the capacitor body 2 and bringing the probe of the inspection device into contact therewith.
In a state where the capacitor 1 is housed in the component housing recess 6 of the carrier tape 5, its characteristics, for example, the capacitance, the tangent of the loss angle, the leakage current, and the like can be inspected.

Although the above embodiment is directed to a case where an electric double layer capacitor is used as a series of electronic components, the series of electronic components is not limited to this, and for example, a coin type in which lead terminals are similarly drawn out in the same direction. It also applies to batteries and the like.

〔The invention's effect〕

As described above, according to the present invention, the electronic components housed in the carrier tape do not rotate due to vibration or impact during transportation, and the electronic parts are housed in the carrier tape. Provided is a series of electronic components capable of inspecting the characteristics and the like of components.
