Is mounted in a state where it is positioned at one end opening of the glass tube 30. Then, the fluorescent paint 32
Is applied to the inner peripheral surface of the glass tube 30 in a state where only one of the gaps formed between the strip-shaped aluminum electrodes with connection terminals 35 is opened, thereby improving the illuminance. Is being planned. When the electrodeless lamp is used, a cap (not shown) is fitted into one end of the glass tube 30 so as to cover both connection terminals 35a, and the insulating resin 43 is placed in the cap. It is in a filled state. In the figure, 36 is a connection code.

The strip-shaped aluminum electrode 35 with connection terminals is made of a single piece of aluminum foil, and a rectangular connection terminal 35a is formed from the top (one end) of the strip-shaped aluminum electrode portion 35b. (The width of the connection terminal 35a is narrower than the aluminum electrode portion 35b). Then, the aluminum electrode portion 35b and the base end of the connection terminal 35a are adhered to one surface of the transparent film 34 via a film-side adhesive layer, and the front end of the connection terminal 35a (a part beyond the base end). Project from the outer peripheral portion of the transparent film 34.

In order to automate and simplify the operation for attaching such electrode members 33 to the outer peripheral surface of the glass tube 30, a large number of electrode members 33 as shown in FIG. Utilizing the adhesive force of the layer and the adhesive layer for electrode attachment, a film-like electrode 38 detachably attached to a belt-like separator 37 is mechanically manufactured in a series, and then the electrode members 33 are separated from the separator 37 one by one. It has been proposed to peel it off and attach it to the outer peripheral surface of the glass tube 30.

The film-like electrode 38 can be manufactured, for example, as follows. That is, as shown in FIG. 10, an acrylic pressure-sensitive adhesive is first applied to a portion of one surface of the strip-shaped separator 37 other than a portion corresponding to the tip of the connection terminal 35a by a comma coater or the like, and the electrode is formed. An aluminum electrode substrate 39 (roll-shaped winding) obtained by forming a pressure-sensitive adhesive layer and dry laminating a band-shaped aluminum sheet 39a on one surface of the band-shaped separator 37 from above the electrode-adhesive layer. Prepare body). Then, the aluminum sheet 39a on the surface is half-cut by the half-cutting device 20 while feeding the aluminum electrode base material 39 in a strip shape, thereby forming a strip-shaped aluminum electrode with connection terminals (a protruding portion is provided at one end portion). (The cut portion is indicated by a dotted line L ₁₁₎
). At this time, the rectangular aluminum electrodes 35 each having a pair of connection terminals are arranged side by side at a predetermined interval. The connection terminals 35a are all formed so as to face in the same direction. Next, the unnecessary portion of the aluminum sheet 39 is removed by the unnecessary aluminum removing device 21.
By stripping a sequentially, a pair of strip-shaped aluminum electrodes 35 with connection terminals is formed. In this manner, the electrode-attached film 4 in which the strip-shaped aluminum electrodes 35 with connection terminals are attached to the multi-set separator 37
0 is obtained and wound up in a roll. When the unnecessary aluminum portion is peeled off, the pressure-sensitive adhesive layer for electrode attachment at that portion is removed together with the unnecessary aluminum portion.

On the other hand, a silicone-based pressure-sensitive adhesive is applied to one surface of a strip-shaped transparent film 34 by a comma coater or the like, and a laminated film 41 having a film-side pressure-sensitive adhesive layer formed thereon.
Is prepared (see FIG. 11). The width of the transparent film 34 is smaller than the width of the separator 37,
The tip of the connection terminal 35 a is made to protrude from the outer periphery of the transparent film 34. In addition, the laminated film 41
When a roll-shaped wound body is used for easy transportation and storage, a separator for protecting the pressure-sensitive adhesive layer is attached to the surface of the pressure-sensitive adhesive layer on the film side, and the separator for protecting the pressure-sensitive adhesive layer is used at the time of use. May be peeled off.

As shown in FIG. 11, the electrode-attached film 40 and the laminated film 41 (both in a rolled form) are fed out and passed between the opposing movable rollers 22 so that the electrode-attached film 40 is formed. Surface of the strip-shaped aluminum electrode 35 with connection terminals and the laminated film 4
The film-side pressure-sensitive adhesive layer-forming surface of No. 1 is joined to integrate them. At this time, in the integrated film, the strip-shaped aluminum electrode 35 is covered with the transparent film 34, and the separator 37 side is kept in a flat state.

Next, the half-cut device 23 cuts the transparent film 34 of the integrated film so that a pair of strip-shaped aluminum electrodes 35 with connection terminals are covered with the transparent film 34 for each group. put the L _12. The cut L ₁₂ are two between pairs adjacent to each other. After that, the unnecessary portion 34 of the transparent film 34
a is removed, and the film electrode 38 is completed. The film-shaped electrode 38 completed in this manner is wound into a roll and supplied to a production line for an electrodeless lamp.

In the production line of the electrodeless lamp,
First, the film-shaped electrode 38 (roll-shaped wound body) is paid out, and is separated into the electrode member 33 and the separator 37 during the feeding. After this separation, the electrode member 33 is supplied to the glass tube 30 transport line, and is adhered to the outer peripheral surface of each glass tube 30. This sticking is performed such that the two strip-shaped aluminum electrodes 35 with connection terminals of the electrode member 33 face each other with the two connection terminals 35a positioned at one end of the glass tube 30. Will be Thus, the electrodeless lamp is completed.

However, the above-mentioned film with electrode 40,
Inspection, packing,
When the connection terminal 35a is hooked or applied to a hand or a surrounding object when being transported, stored, or the like, or when the film 40 with electrodes and the film-shaped electrode 38, which are roll-shaped winding bodies, are fed out, The connection terminal 35a is bent or bent. This is because the strength of the connection terminal 35a is insufficient because the connection terminal 35a is formed integrally with the aluminum electrode portion using aluminum foil.

Therefore, in order to compensate for the insufficient strength of the connection terminal 35a, another aluminum sheet piece 42 is provided on the top of the connection terminal 35a and the aluminum electrode portion 35b as shown in FIGS. 12 (a) to 12 (c). 13 (a) to 13 (c), as shown in FIGS. 13 (a) to 13 (c), another aluminum sheet piece 42 is bonded to the connection terminal 35a to form a two-layer structure, thereby increasing strength. There is something that aimed at. In this case, the attachment of the aluminum sheet piece 42 may be on the front surface or the back surface of the connection terminal 35a or the like.

In the case of manufacturing such a film-shaped electrode, an acrylic adhesive is applied to one surface of the strip-shaped separator 37 and a strip-shaped aluminum sheet 39a is dry-laminated in the same manner as in the above-mentioned conventional technique. Then, an aluminum tape having an adhesive layer formed on the back surface is adhered to one end (the end on which the connection terminal 35a is formed) to prepare a base material for an aluminum electrode with an aluminum tape. Next, the aluminum sheet with the aluminum tape on the surface is half-cut into a predetermined shape by a rotary cutter or a die cutter while the base material for an aluminum electrode with an aluminum tape is unwound in a strip shape. Thereby, the aluminum sheet piece 42 is placed on top of the connection terminal 35a and the aluminum electrode portion 35b.
Is obtained. After that, a film-like electrode is manufactured through the same steps as in the above-described conventional technique.

[0014]

However, if the connection terminals 35a and the tops of the aluminum electrode portions 35b have a two-layer structure, the aluminum tape is required. For this reason, the material cost and management cost of the aluminum tape and the pressure-sensitive adhesive increase, and the manufacturing cost increases.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a terminal structure for connecting a film-shaped electrode at a low manufacturing cost.

[0016]

In order to achieve the above object, a connection terminal structure for a film-like electrode according to the present invention comprises a plurality of connection terminals made of metal foil on one surface of a transparent film via an adhesive layer. By arranging strip-shaped electrodes with terminals for use side by side, an electrode member is formed, and the electrode member is peelable on one surface of the separator in a state in which at least a part of the connection terminal protrudes from the outer peripheral portion of the transparent film. Attached, said connection terminal is a film-shaped electrode integrally formed of the same material as the strip-shaped electrode, and a reinforcing ridge or a concave stripe is formed on a terminal surface of the connection terminal. Take the configuration.

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the connection terminal structure of the film electrode 1 of the present invention. In this embodiment, the film-shaped electrode 1 is arranged in parallel with a separator 2 made of a PET band-shaped sheet having one surface subjected to a release treatment, and on one surface of the separator 2 in a state orthogonal to the longitudinal direction. And a plurality of sets of electrode members 3. The electrode member 3 includes a transparent film 4 made of PET,
The transparent film 4 includes a pair of strip-shaped aluminum electrodes 5 with connection terminals arranged side by side on one surface. The transparent film 4 and the strip-shaped aluminum electrode 5 with both connection terminals are adhered by a film-side pressure-sensitive adhesive layer 6 (consisting of a silicone-based pressure-sensitive adhesive layer) formed on the entire surface of the transparent film 4. On the exposed surface of the strip-shaped aluminum electrode 5 with connection terminals (the surface opposite to the surface to which the transparent film 4 is adhered), an acrylic adhesive is applied to the exposed surface excluding the tip of the connection terminal 5a to be described later. An electrode-applied pressure-sensitive adhesive layer 7 composed of a layer is formed. Each electrode member 3 is detachably attached to one surface of the separator 2 by utilizing the adhesive force between the film-side pressure-sensitive adhesive layer 6 and the electrode sticking pressure-sensitive adhesive layer 7.

The strip-shaped aluminum electrode 5 with connection terminals is made of one piece of aluminum foil, and is formed from the top (one end) of the strip-shaped aluminum electrode portion 5b.
The connection terminal 5a formed in a rectangular shape (the connection terminal 5a
Is narrower than the aluminum electrode portion 5b). On the terminal surface of the connection terminal 5a, one ridge 8 is formed long along the longitudinal direction of the connection terminal 5a. And the aluminum electrode part 5
b and the base end of the connection terminal 5a are adhered to one surface of the transparent film 4 via the film-side adhesive layer 6, and the connection terminal 5a
Of the transparent film 4 protrudes from the outer peripheral portion of the transparent film 4. In addition, the aluminum electrode portion 5b and the base end of the connection terminal 5a are detachably attached to one surface of the separator 2 via the electrode sticking adhesive layer 7, as described above.

The film electrode 1 can be manufactured, for example, as follows. That is, first, an acrylic pressure-sensitive adhesive is applied to a portion of one surface of the strip-shaped separator 2 other than the portion corresponding to the tip of the connection terminal 5a using a comma coater, a lip coater, a reverse coater, a fauten coater, a gravure coater, or the like. To form a pressure-sensitive adhesive layer 7 for electrode application, and a band-shaped aluminum sheet 9a is dry-laminated on one surface of the band-shaped separator 2 from above the pressure-sensitive adhesive layer 7 for electrode application. A base material 9 (roll-shaped wound body) is prepared. Next, as shown in FIG. 4, while the aluminum electrode base material 9 is being unwound in a strip shape, the aluminum sheet 9a on the surface is cut by a rotary cutter (not shown, an outer peripheral surface of the rotary cutter is connected to a half cutter 20). A half-cut is performed with a cutter portion having a shape corresponding to the aluminum electrode 5 with a terminal), and the electrode shape of the strip-shaped aluminum electrode 5 with a connection terminal (a strip shape having a protruding portion at one end). to express (indicating the cut portion by a dotted line L _1). At this time, the two rectangular aluminum electrodes 5 with connection terminals are arranged side by side at a predetermined interval. The connection terminals 5a are all formed so as to face in the same direction. Next, the unnecessary aluminum sheet 9a is sequentially peeled off by the unnecessary aluminum removing device 21 to form a pair of strip-shaped aluminum electrodes 5 with connection terminals. Next, the ridges 8 are formed on the terminal surfaces of the connection terminals 5a by the ridge forming press device 24. The ridge 8 is formed by the ridge forming press device 24 by pressing the ridge member against the separator 2 corresponding to the lower part of the terminal surface of the connection terminal 5a. For this reason, as shown in FIGS. 3A to 3C, the back surface corresponding to the protruding ridge 8 of the terminal surface is a concave ridge 10. In this way, a plurality of sets of strip-shaped aluminum electrodes 5 with connection terminals are obtained, and the film 11 with electrodes attached to the strip-shaped separator 2 via the pressure-sensitive adhesive layer 7 for electrode attachment is obtained and wound into a roll. When the unnecessary aluminum portion is peeled off, the pressure-sensitive adhesive layer 7 for attaching the electrode at that portion is removed together with the unnecessary aluminum portion.

The subsequent steps are performed in the same manner as in the above-mentioned conventional technique. That is, to briefly explain, as shown in FIG. 5, the above-mentioned electrode-attached film 11 and the prepared laminated film 12 (both roll-shaped winding bodies) are unwound and passed between opposing movable rollers 22. The two are integrated. Then, it scored L ₂ by a half-cut device 23 to the transparent film 4 of the integrated film, removing unnecessary portions 4a of the transparent film 4, film-like electrode 1 is completed. The film-like electrode 1 completed in this way is wound into a roll and supplied to a production line for an electrodeless lamp. Then, in the production line of the electrodeless lamp, first, the film-shaped electrode 1 (roll-shaped wound body) is fed, and in the middle of the feeding, separated into the electrode member 3 and the separator 2 and the outer peripheral surface of each glass tube. Stick it on In this attachment, the two strip-shaped aluminum electrodes 5 with connection terminals of the electrode member 3 are connected to both connection terminals 5a.

According to the terminal structure for connection of a film-shaped electrode of this embodiment, since the ridges 8 are formed on the terminal surface of the connection terminal 5a, the rigidity of the connection terminal 5a is increased.
The connection terminal 5a has a strength that is not easily broken or bent. Therefore, unlike the related art shown in FIG. 12, it is not necessary to form the connection terminal into a two-layer structure in order to increase the rigidity of the connection terminal 5a. As a result, an aluminum tape for attaching the connection terminal to the two-layer structure and a step of attaching the aluminum tape are unnecessary, and
Manufacturing costs are reduced.

The material of the transparent film 4 is P
Since ET is used, coloring and discoloration do not occur even when an electrodeless lamp is used. Further, since the width of the transparent film 4 is smaller than the width of the separator 2, the film-side pressure-sensitive adhesive layer 6 does not adhere to the movable roller 22 or other rollers.

The film-side pressure-sensitive adhesive layer 6 has a siloxane bond [-(SiO) n-] since a silicone-based pressure-sensitive adhesive is used as a material for forming the film-side pressure-sensitive adhesive layer 6. Excellent in heat resistance, water repellency, electrical insulation (high volume resistivity), chemical resistance and aging resistance. In addition, since this silicone-based pressure-sensitive adhesive is resistant to light and temperature changes, even when used in an electrodeless lamp, its pressure-sensitive adhesive strength is not reduced, and excellent pressure-sensitive adhesive strength can be maintained for a long period of time.

Since an acrylic pressure-sensitive adhesive is used as a material for forming the pressure-sensitive adhesive layer 7 for attaching an electrode, the electrode member 3 can be firmly adhered to a glass tube of an electrodeless lamp and can be obtained at low cost. In addition, since the acrylic pressure-sensitive adhesive is resistant to light and temperature changes, its adhesive strength does not decrease even when used for an electrodeless lamp, and excellent adhesive strength can be maintained for a long period of time.

When the number of cuts L ₂ to be inserted into the transparent film 4 of the integrated film is set to two between adjacent sets, a gap is formed between the _two cuts L _2. The gap facilitates mechanical separation of the electrode member 3 and the separator 2 in the electrodeless lamp production line.

In the manufacturing process of the film electrode 1, the strip-shaped aluminum electrode 5 with connection terminals was attached to the strip-shaped separator 2.
After this, the film with electrodes 11 is wound up in a roll shape, but without being wound up in a roll shape,
After obtaining the above-mentioned electrode-attached film 11, the electrode-attached film 11 and the laminated film 12 in which the film-side pressure-sensitive adhesive layer 6 is formed on one surface of the strip-shaped transparent film 4 may be integrated.

Although a plurality of sets of the electrode members 3 are arranged on one surface of the strip-shaped separator 2, one set of the separators 2 may be detachably attached to each set.

The connection terminal 5a is formed integrally with the top of the aluminum electrode portion 5b. However, the present invention is not limited to this. The connection terminal 5a is formed integrally with the other portion of the aluminum electrode portion 5b. May be done.

The protruding ridges 8 are provided over the portion of the connection terminal 5 a protruding from the transparent film 4 and the portion covered with the transparent film 4, but may be provided only on the portion protruding from the transparent film 4.

Further, the order of the steps of forming the ridges 8 in the above embodiment is not particularly limited, and the steps from the half cutting step of the aluminum sheet 9a on the surface of the separator 2 to the bonding of the electrode member 3 to the glass tube. Any time as long as it is before the wearing step. In addition, a press device 2 for forming a ridge is provided.
The formation of the ridge 8 by 4 may be performed by pressing the ridge member above the terminal surface of the connection terminal 5a.

In the above-described embodiment, a rotary cutter is used for the half-cutting device 20. However, a die cutter which can form the ridge 8 on the terminal surface of the connection terminal 5a when the aluminum sheet 9a is half-cut is used. May be used.
