Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic component chain, and more particularly to an electronic component chain in which a plurality of electronic components are connected and attached by tape-forming lead terminals connected to the electronic components.

For example, conventional terminal members used for electronic components such as capacitors, resistors, and hybrid integrated circuits use a conductive metal plate and have two perforations arranged at a constant pitch in a strip 1, as shown in Fig. 1. It has a structure in which a large number of lead terminals 3 are lined up at regular intervals and protrude from the side edge of the band-shaped part 1.As shown in Fig. 2, the lead terminals 3 are used as electrodes for electronic components. An electronic component series is formed by joining the electronic components by soldering and coating the electronic components with an exterior resin.

The above-mentioned electronic component A needs to be subjected to measurement and selection of capacitance etc. in the final process, but as mentioned above, the conventional terminal member
Since each lead terminal 3 is connected by the band-shaped portion 1, measurement cannot be performed as it is, and therefore each lead terminal 3 must be cut to separate the electronic component A individually.

Incidentally, in recent years, there has been a desire to automate the mounting of electronic components onto printed circuit boards, etc. in order to improve efficiency and save labor, but if the electronic components are separated, automatic mounting requires rotation, which slows down shipping. There is also the problem that packaging for the product is also troublesome.

This invention was made to solve the above-mentioned problems, and provides an electronic component series that can be easily attached to a printed circuit board etc. by taping the electronic components, and can be easily packaged for shipping. The purpose is to

The structure of the present invention is such that an electrically insulating tape member having a width wider than the strip portion is fixed to the strip portion of a terminal member having a large number of lead terminals protruding from the strip portion, and between each lead terminal of the strip portion. Separation holes are punched together with the tape member so that each lead terminal is held by the tape member even after being separated, and electronic components are attached to the lead terminals.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 11.

The electronic component series of the present invention includes a terminal member 13 made of a conductive metal plate such as nickel silver, and having a large number of lead terminals 12 arranged at regular intervals and protruding from the side edge along the longitudinal direction of a band-shaped portion 11; The tape member 14 is fixed to the strip portion 11, and separation holes 15 are formed in the strip portion 11 between each lead terminal 12. It is formed by punching together with the tape member 14, so that each electrically independent lead terminal 12 is held by the tape member 14, and an electronic component is attached to each lead terminal 12. .

Various structures can be adopted for the structure of the tape member 14 and for fixing it to the band-shaped portion 11. In the first example shown in FIGS. 3 and 4, the tape member 14 uses a cardboard mount 14a. The fixation to the strip-shaped portion 11 is performed by pasting with an adhesive layer 14b applied to the surface of the mount 14a. After the mount 14a is pasted to the strip-shaped portion 11, a mount is attached on both sides between each lead terminal 12 of the strip-shaped portion 11. Separation hole 15 leaving 14a
Further, feed holes 16 are punched out on the mount 14a at the same time using an automatic press machine, and the lead terminals 12 are made independent by the separation holes 15 and held by the mount 14a. Note that the adhesive layer 14b is the mount 14 in the illustration.
a It is applied to the entire surface, but at least the band-shaped part 1
1 may be applied to the area to be bonded.

In the second example shown in FIGS. 5 and 6, the tape member 14 is connected to a mount 14a wider than the strip portion 11 and an adhesive tape 14c.
In this case, the strip-shaped portion 11 of the terminal member 13 is stacked on the mount 14a, and the strip-shaped portion 11 is sandwiched by laminating both sides of the adhesive tape 14c stacked on the strip-shaped portion 11 to the mount 14a. Separation holes 15 are formed by punching together with the mount 14a and the adhesive tape 14c at positions between the respective lead terminals 12 of the rear band-shaped portion, and feed holes 16 are simultaneously bored in the mount 14a. This feed hole 16 may be formed so as to penetrate both the mount 14a and the adhesive tape 14c.

The third example shown in FIGS. 7 and 8 uses a mount 14a wider than the strip portion 11 for the tape member 14, and the strip portion 1
1 and the mount 14a are fixed using piercing claws 17 provided for each lead terminal 12 on both side edges of the strip-shaped portion 11, and the mount 14a stacked on the strip-shaped portion 11 is fixed downwardly. Bent sharp piercing claw 1
After fixing both by bending the tips of the piercing claws 17 on the back surface of the mount 14a, a separation hole 15 is formed in the band-shaped portion 11 and a feed hole 16 is formed in the mount 14a.

Note that if the mount 14a has a cut in advance into which the stabbing claw 17 can be inserted, the stabbing claw 17 does not need to be particularly sharp.

A fourth example shown in FIGS. 9 and 10 is a case in which the tape member 14 is made of a flexible synthetic resin such as vinyl chloride, and a mold is used to cover the band-shaped portion 11. After integral molding, separation holes 15 and feed holes 16 are bored.

In both examples, the required electronic components Δ are attached to each lead terminal 12 and covered with an exterior material to form an electronic component chain. The number of electronic components used can be freely selected depending on the circuit configuration of the electronic component A, and the feed hole 16 for automatic mounting can be omitted by using the separation hole 15.

Furthermore, the terminal member 13 is not limited to one in which the lead terminal 12 is provided on one side of the band-shaped portion 11, but as shown in FIG. The electronic component A may be connected to the opposing lead terminals 12 on both sides. In this case, one of the tape members shown in the first to fourth examples is attached to the strip portions 11 on both sides, and the separation holes 15 are provided. All you have to do is set up the following.

The electronic component series of the present invention has the above-described configuration, and after the lead terminal 12 of the terminal member 13 is connected to the electronic component A by soldering, a wide tape member 1 is attached to the band-shaped portion 11.
4 is fixed, and a separation hole 15 and a tape member 1 are attached to the strip portion 11.
A feed hole 1G is formed in the tape member 1 to make each lead terminal 12 independent, or the tape member 1 is fixed to the strip portion 11.
4 to make each card terminal 12 independent, electronic component A is soldered to lead terminal 12. The exterior material covering the electronic component is applied by appropriate means such as dipping or molding.

After that, by measuring the characteristics of each electronic component using the lead terminal 12, the series of electronic components held by the tape member 14 is completed, and the tape member 14 is wound into a roll and packaged. The electronic component A can be mounted on a printed circuit board by setting it in an automatic mounting machine in its tape form and feeding it intermittently through the feed hole 16 to cut the lead terminal 12 at a predetermined position. .

As described above, according to the present invention, a wide tape portion (A) is fixed to the strip-shaped portion of the terminal member in which a large number of lead terminals are provided on the strip-shaped portion. Since a separation hole is provided in the , each lead terminal connected to the electronic component by soldering can be made independent and at the same time be held and covered by the tape material, making it possible to measure the performance of the electronic component while it is in the taped state. Depending on the situation, it is possible to automatically attach electronic components to printed circuit boards.

In addition, it becomes possible to ship electronic components by winding them in a tape state, making it easy to package electronic components.
