BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber connector with a carrier tape which is improved so that it can be automatically supplied to an assembly machine for electronic devices.

[0002]

2. Description of the Related Art As electronic devices have become more complex in recent years, the number of built-in IC substrates has increased dramatically, which has spurred miniaturization. For connecting the terminal electrodes of the small IC substrate, for example, a zebra-type bar-shaped rubber connector (hereinafter referred to as a single unit) in which conductive rubber members and insulating rubber members are alternately and multiply laminated and integrated.
Rubber connector) is used. This rubber connector can be stored separately in a plastic bag, for example
As shown in, the rubber connector 1, attached by pressure sensitive adhesive 4 to one side 2 not pressed against the terminal electrodes of the wiring board to mount 3 which is surface treated with a parting agent, holding the opposite surface 5 of the side surface The film 6 is attached and taken out from the bag as required, or peeled off from the mount 3 and used.

[Problems to be Solved by the Invention] However, in the former case, it is time-consuming to check the quantity of delivery, and because the rubber connector is small and has elasticity, it is equivalent to the worker to determine the conductive direction between the terminal electrodes and attach them in the correct direction. This will result in the burden of On the other hand, the latter has solved these disadvantages to some extent, but the burden on the operator for properly setting a large number of rubber connectors has not been alleviated. Therefore, the appearance of a device that can automatically supply a rubber connector to an assembling machine has been struggling, but especially in the case of a module with a relatively large dot size (0.4 mm or more) for calculators, watches, remote controllers, etc. There is a great demand for automation.

[0004]

SUMMARY OF THE INVENTION The present invention solves these conventional problems by providing a plurality of bar-shaped rubber connectors in which conductive rubber members and insulating rubber members are alternately laminated and integrated. One surface that is not involved in connection is the pasting surface
In addition, the adhesive surface of the carrier tape having a front surface having adhesiveness and a back surface having releasability so that they are arranged in parallel adjacent to each other.
The gist is a rubber connector with a carrier tape, which is characterized by being attached to the surface .

The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a rubber connector with a carrier tape of the present invention wound on a reel 7, in which the rubber connector 1 has an adhesive surface,
A carrier tape whose back surface is releasable (hereinafter simply referred to as carrier tape
Parallel adjacent in a row through the pressure sensitive adhesive 4 to the referred to flop) 8
And is attached. At this time, the adhesive surface of the rubber connector should be the pressure contact surface that contacts the terminal electrode when connecting the wiring board.
In order not to be contaminated , one surface other than the pressure contact surface , in other words, one surface not involved in the connection is used.

By setting this on the reel 7 in the winding and assembling machine, the rubber connector 1 can be supplied very easily. As shown in FIG. 2, the reel 7 has a side plate 10 pressure-bonded to a paper tube 9 and is fixed by a side plate retainer 11. Adhesion of the rubber connector 1 to the carrier tape 8 is wound outside when wound on the reel. That is, the sticking surface of the rubber connector may face outward or, on the contrary, may be wound inside. Carrier tape 8 is rubber connector 1
The surface for affixing the pressure-sensitive adhesive 4, the back surface is coated with a parting agent. But more is better outside winding to avoid the rubber connector 1 each other of the pressure-sensitive adhesive.

The carrier tape base material is a plastic film such as fluororesin, paper, natural fiber cloth, synthetic fiber cloth,
Examples include glass fiber cloth, paper in which a plastic film is laminated, and paper or cloth in which synthetic resin is impregnated or coated. Considering handleability, kraft paper and polyester film are preferable. The thickness of the carrier tape base is 0.1 m considering workability and handling.
About m to 0.5 mm is desirable.

As the pressure-sensitive adhesive, conventionally known ones such as epoxy resin-based and acrylic resin-based adhesives and pressure-sensitive adhesives are used. The adhesive force between the pressure-sensitive adhesive 4 and the rubber connector 1 needs to be appropriately determined so that it is intentionally peeled off when peeled off and not peeled off during transfer. Specifically, when the rubber connector 1 is made of silicone rubber, It is preferable to adjust the adhesive strength to be 100 g to 200 g with a width of 5 mm.

[Example] As a carrier tape, Nitto Craft Tape No. 718 (trade name, manufactured by Nitto Denko Corporation) and polyester film No. 646S (Teraoka Seisakusho Co., Ltd., trade name) was equipped with. It is adjacent to the parallel longitudinal direction of each rubber connectors to each and contact the rubber connector
Adhere one side that is not involved in the continuation to the carrier tape,
Then, each reel was wound on the outside. These were set in individual automatic assembly machines, but the rubber connectors were supplied very smoothly.

[0010]

EFFECT OF THE INVENTION Since the rubber connectors are adhered in parallel to each other and one surface not involved in the connection, they can be automatically supplied to the assembly machine in the correct direction, and
Since the connecting surface is free of contamination, it has a remarkable effect on improving efficiency and yield.
