Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a taped electronic component in which an electronic component is held on a tape.

[Conventional technology]

As shown in FIG. 2, in the conventional taped electronic component, leads 4a, 4b of an electrolytic capacitor or the like are placed on a support tape 2, and an adhesive tape 6 is applied over the leads 4a and 4b.
is attached to hold the electronic component 8.
Note that 10 is a sprocket hole.

[Problem that the invention attempts to solve]

By the way, the leads 4a and 4b of the electronic component 8 are thin and the bonding area with the adhesive tape 6 is extremely small, so if the holding strength of the electronic component 8 is low, the electronic component 8 may fall off from the support tape 2 during handling. Sometimes.

In particular, as the electronic component 8 becomes smaller, the lead 4 becomes smaller.
As leads a and 4b become thinner, the gap between them also becomes narrower, so the adhesive tape 6 rises within the gap between the leads 4a and 4b, making it impossible to adhere to the support tape 2 and reducing the holding strength of the electronic component 8. . The adhesive tape 6 holds the electronic component 8 and is pressed down by a pressure means such as a roller.
If the distance between the leads 4a and 4b is narrow, pressure from a pressure means such as a roller cannot be applied within that distance.

For this reason, in the past, as shown in Utility Model Publication No. 57-23918 "Electronic Components Series", methods such as increasing the holding strength by bending the leads to widen the gap and preventing the adhesive tape from lifting have been proposed. Efforts have been made.

However, in the part where the adhesive is held, the electronic component 8
In the child component 8 as well, the leads 4a and 4b are bent in different directions, which actually impedes the adhesive strength and has disadvantages such as poor workability.

Furthermore, since the taped electronic component held by the adhesive tape 6 is heavy on the component body side, when force is applied to the component body side, the leads 4a and 4b bend due to the adhesive force of the adhesive tape 6. There were inconveniences such as deterioration of workability during wiring.

Therefore, this invention prevents the adhesive strength from decreasing, improves the possibility of electronic components falling off, and prevents the leads from bending.

[Means for solving problems]

The taped electronic component of this invention includes an electronic component 8 in which at least two leads 4a, 4b protruding from the end of a component body with a constant interval, and a constant width of the leads in accordance with the interval between the leads. Protrusions 12 to be maintained at intervals of 2 are bonded to a support tape 2 formed at intervals that can support the component main body in a non-contact state, and are adhered to the support tape to hold the leads of the electronic component on the support tape. It is equipped with an adhesive tape 6 to hold it in place.

[Effect]

With this configuration, since the protrusions 12 provided on the support tape 2 are interposed between the leads 4a and 4b and the leads 4a and 4b are held by the adhesive tape 6, the protrusions 12 allow the leads 4a and 4b is reinforced and sufficient holding strength is obtained.

Furthermore, since the leads 4a and 4b are reinforced by the protrusions 12, deformation of the leads 4 is prevented even if force is applied to the component body.

〔Example〕

FIG. 1 shows an embodiment of the taped electronic component of this invention.

Projections 12 are provided on the surface of the support tape 2 at regular intervals in accordance with the interval between at least two leads 4a, 4b drawn out at regular intervals on the end face of the component body of an electronic component 8 such as an electrolytic capacitor. The height of the protrusion 12 is, for example, the height of the installed lead 4.
The surfaces of a and 4b are exposed from the surface of the protrusion 12.

When the leads 4a and 4b of the electronic component 8 are arranged on both sides of the protrusion 12 of the support tape 2 and the adhesive tape 6 is attached, the leads 4a and 4b of the electronic component 8 are
b is positioned on both wall surfaces of the protrusion 12, and
It is restrained and held by the adhesive tape 6. In particular, since the adhesive tape 6 is attached from the upper surface of the protrusion 12 along the protruding portion made up of the leads 4a and 4b, the adhesive strength of the adhesive tape 6 is not hindered, and sufficient holding strength can be obtained.

Since the leads 4a and 4b are reinforced by the protrusion 12, even if force is applied to the component body,
Deformation such as bending of the leads 4a and 4b can be prevented, and workability during wiring will not be deteriorated.

[Effect of idea]

As explained above, according to this invention, the protrusions have a width corresponding to the spacing between at least two leads drawn out to the end face of the component body, and are spaced apart enough to support the component body in a non-contact state. By forming the lead on the support tape, the lead of the electronic component can be placed on the support tape with this protrusion in between, and the adhesive tape can be glued on top of it, increasing the strength of holding the lead and preventing the lead from moving or electronic components. Inconveniences such as parts falling out, deformation of leads, and changes in lead spacing can be prevented, and automatic insertion into printed wiring boards etc. can be performed accurately, contributing to increased efficiency of automatic mounting.
