And a connection method for connecting terminals of an electronic circuit to each other.

  Conventionally, a flexible insulating material (for example, cloth, resin, string, or the like) in which a linear conductor (for example, a conductive line, conductive yarn, copper film, or the like) is incorporated has been used. In addition, a light emitter (for example, LED, light bulb, etc.) is connected to the linear conductor incorporated in the insulating material in this way, and the light emitter is caused to emit light by the electric power supplied through the linear conductor. Such a technique has been devised.

  For example, in Patent Document 1 below, a light-emitting string is constructed by incorporating a small light-emitting diode inside a string in which conductive fiber or conductive yarn is incorporated, and connecting the small light-emitting diode to the conductive fiber or conductive thread. Techniques to do this are disclosed.

  Patent Document 2 below discloses a belt-like light emitter including a linear or belt-like lead, a belt-like covering for covering the lead, and a light emitting lamp attached to the belt-like covering and connected to the lead. ing.

Utility Model Registration No. 3132323 Japanese Utility Model Publication No. 5-43184 Japanese Utility Model Publication No. 5-16400

  In the light-emitting string described in Patent Document 1, in order to connect the small light-emitting diode to the conductive yarn, the conductive thread woven into the string is cut, and a chip of the small light-emitting diode is inserted into the cut portion. The electrode must be secured to the conductive yarn by soldering or adhesive. For this reason, the light-emitting string described in Patent Document 1 cannot easily connect the chip to the conductive yarn.

  Moreover, in the strip | belt-shaped light-emitting body of the said patent document 2, the structure which inserts the lead terminal of the socket of a miniature light bulb through the resin surface of a strip | belt-shaped covering body, and is made to contact is employ | adopted. However, in Patent Document 2, the lead terminal is not fixed to the lead. Therefore, the lead terminal cannot be reliably connected to the lead, and there is a risk of poor contact of the lead terminal.

  Further, in the belt-like light emitter described in Patent Document 3, in order to connect the light emitter to the two conductors, the light emitter must be connected between the two conductors by soldering or the like. Moreover, in order to add a light-emitting body, you have to peel off the insulating sheet which coat | covers two conducting wires, and must expose two conducting wires. Therefore, the light emitters cannot be easily connected.

  Thus, in the prior art, there has been a problem that the light emitter cannot be easily and reliably connected to the linear conductor incorporated in the insulating material having flexibility.

  The present invention has been made to solve such problems, and can easily and reliably connect an electronic circuit to a linear conductor incorporated in an insulating material having flexibility. The purpose is to do so.

  In order to solve the above-described problems, an electronic device according to the present invention is mounted on a surface of an insulating material having a flexible sheet-like insulating material in which a plurality of linear conductors are arranged in parallel. And an electronic circuit having a plurality of terminals on the substrate. In particular, in the electronic device according to the present invention, each of the plurality of terminals is aligned with the connection-destination linear conductor, and the conductive metal is caulked through the terminal and the connection-destination linear conductor. The grommet made of material is connected to the connected linear conductor so as to be able to conduct each other.

  According to the electronic device of the present invention configured as described above, the eyelet is placed between the linear conductor incorporated in the flexible sheet-like insulating material and the terminal formed on the substrate of the electronic circuit. The terminal and the linear conductor can be connected to each other so as to be conductive only by performing a simple operation such as penetrating and crimping the eyelet. In particular, since the terminal and the linear conductor are connected with relatively strong strength by the crimped eyelet, the connection between the two is not released, and there is no contact failure between the two. . For this reason, according to the electronic device of the present invention, it is possible to easily and reliably connect the electronic circuit to the linear conductor incorporated in the flexible insulating material.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[Configuration of Light Emitting Device 10]
First, with reference to FIG. 1, the structure of the light-emitting device 10 which concerns on one Embodiment of the electronic device by this invention is demonstrated. FIG. 1 is a plan view showing an overall configuration of a light emitting device 10 according to the present embodiment. As shown in FIG. 1, the light emitting device 10 includes a light emitting unit 100 and a power supply unit 150.

  The light emitting unit 100 includes a plurality of LED circuits 110 arranged in parallel on the surface of the ribbon 102. The ribbon 102 is an example of a sheet-like insulating material having flexibility, and is a belt-like cloth made of a fiber material. Inside the ribbon 102, a plurality of conductive yarns 104a to 104d are arranged in parallel. Each LED circuit 110 can be connected to any of the plurality of conductive yarns 104a to 104d. In the example shown in FIG. 1, each LED circuit 110 is connected to a plurality of conductive yarns 104b and 104c.

  A terminal substrate 105 is provided at the end of the ribbon 102. The plurality of conductive yarns 104 a to 104 d are connected to the power supply unit 150 through the terminal substrate 105. Each LED circuit 110 causes the LED mounted on the LED circuit 110 to emit light by the power supplied from the power supply unit 150 via the plurality of conductive yarns 104b and 104c. Since the ribbon 102 has flexibility, it can be bent freely. And the light-emitting device 10 can light-emit several LED installed in the ribbon 102 in the state in which the ribbon 102 was bent by arbitrary shapes.

(Detailed configuration of the ribbon 102)
In the example illustrated in FIG. 1, four conductive yarns 104 a to 104 d that are parallel to the longitudinal direction of the ribbon 102 (the y-axis direction in the drawing) are provided inside the ribbon 102. Each of the conductive yarns 104a to 104d is an example of a linear conductor having conductivity. For each of the conductive yarns 104a to 104d, for example, a conventionally known conductive fiber can be used. The conductive yarns 104a to 104d are all parallel. For this reason, the interval between two conductive yarns adjacent to each other is constant in the longitudinal direction of the ribbon 102 (y-axis direction in the figure).

(Detailed configuration of LED circuit 110)
In the example shown in FIG. 1, four LED circuits 110 are arranged in parallel on the surface of the ribbon 102 along the longitudinal direction (y-axis direction in the drawing) of the ribbon 102. Each LED circuit 110 has two terminals. In each LED circuit 110, one terminal is connected to the conductive yarn 104b, and the other terminal is connected to the conductive yarn 104c. That is, the four LED circuits 110 are electrically connected in parallel to the conductive yarns 104b and 104c. On the other hand, the LED circuit 110 is not connected to the conductive yarns 104a and 104d. Each terminal of the LED circuit 110 is connected to the connection destination conductive yarns 104b and 104c by the eyelet 108. Thereby, the light emitting device 10 of the present embodiment can easily and reliably connect the LED circuit 110 to the conductive yarns 104b and 104c.

(Detailed configuration of terminal board 105)
In order to connect the four conductive yarns 104 a to 104 d to the power supply unit 150, four terminals 106 a to 106 d and four connector pins 107 a to 107 d are arranged in parallel on the surface of the terminal substrate 105. On the terminal board 105, the terminals 106a to 106d are aligned with the corresponding conductive yarns 104a to 104d. And each terminal 106a-106d is connected to the conductive yarn 104a-104d by the eyelet 108 similarly to the connection structure of the terminal 114a, 114b of the LED circuit 110, and the conductive yarn 104b, 104c. Thereby, the light emitting device 10 of the present embodiment can easily and reliably connect the terminal substrate 105 to the conductive yarns 104a to 104d. Corresponding connector pins 107a to 107d are soldered to the terminals 106a to 106d. Each of the connector pins 107a to 107d protrudes outward from the terminal board 105 so as to be inserted into the corresponding insertion ports 156a to 156d of the connector 155 provided in the power supply unit 150.

(Detailed configuration of power supply unit 150)
The power supply unit 150 is a device that is connected to the plurality of conductive yarns 104a to 104d via the terminal substrate 105 and supplies power to each of the plurality of LED circuits 110 via the plurality of conductive yarns 104a to 104d. The power supply unit 150 includes a power supply unit 152, a cord 154, and a connector 155.

  In the power supply unit 152, a secondary battery 152a such as a lithium ion battery is mounted inside a resin casing. A switch 152b is provided on the surface of the housing. The switch 152b switches the supply of power from the secondary battery 152a between on and off. A cord 154 for supplying power is drawn from the power supply unit 152. A connector 155 is provided at the tip of the cord 154. The connector 155 is connected to four connector pins 107 a to 107 d provided at the end of the ribbon 102. For this reason, the connector 155 is provided with four insertion ports 156a to 156d into which four connector pins 107a to 107d can be inserted.

  In the example shown in FIG. 1, a plurality of LED circuits 110 are connected in parallel to the conductive yarns 104b and 104c. On the other hand, the remaining conductive yarns 104a and 104d are not connected to the LED circuit 110 and are in an open state. For this reason, electric power is supplied from the power supply unit 150 only to the insertion ports 156b and 156c corresponding to the conductive yarns 104b and 104c. However, the light emitting device 10 shown in FIG. 1 can similarly connect the LED circuit 110 to the conductive yarns 104a and 104d. In this case, power is also supplied to the insertion ports 156a and 156d corresponding to the conductive yarns 104a and 104d, and the LED circuit 110 connected to the conductive yarns 104a and 104d can be driven. The power supply unit 150 may include a control circuit that controls light emission of the LED. For example, you may control blinking of LED, a brightness | luminance, lighting time, etc. by a control circuit. Further, the power supply unit 150 is not limited to supplying power from the secondary battery, and may be one that supplies power from an AC power supply, for example.

[Detailed configuration of LED substrate and its connection structure]
Next, a detailed configuration of the LED circuit 110 and the connection structure thereof according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating a configuration of the LED circuit 110 according to the present embodiment, and is a partially enlarged view of the light emitting device 10 illustrated in FIG. 1. In particular, FIG. 2A is a plan view showing the configuration of the LED circuit 110. FIG. 2B is a cross-sectional view of the LED circuit 110 shown in FIG. Note that each of the four LED circuits 110 included in the light emitting device 10 has the same configuration as that shown in FIG.

  The LED circuit 110 includes a substrate 112, terminals 114a and 114b, an LED 116, and a constant current diode 118. The substrate 112 is a thin plate member on which other constituent members are arranged. As the substrate 112, for example, a rigid substrate using a hard plate-like insulator as a material or a flexible substrate using a soft film-like insulator as a material is used.

  The LED 116 is a light emitter installed on the surface of the substrate 112. The LED 116 shown in FIG. 2 has two electrodes. Accordingly, a terminal 114 a connected to one electrode of the LED 116 and a terminal 114 b connected to the other electrode of the LED 116 are formed on the surface of the substrate 112. For the terminals 114a and 114b, a thin film conductor such as a copper film is used.

  The constant current diode 118 converts the drive current of the LED 116 to a constant current. For this reason, the constant current diode 118 is electrically connected in series with the LED 116 on the surface of the substrate 112. The constant current here means that a constant current is always supplied even if the voltage applied to the LED 116 or the load resistance changes. In the example shown in FIG. 2, the constant current diode 118 is provided between the LED 116 and the terminal 114a. The constant current diode 118 makes the driving current of the LED 116 constant, so that the LED 116 can emit light with a predetermined luminance.

  The terminals 114 a and 114 b of the LED circuit 110 are connected to the conductive yarns 104 b and 104 c by the eyelet 108. Specifically, as shown in FIG. 2B, the ribbon 108 and the substrate 112 are crimped to each other by crimping the eyelet 108 passing through the conductive yarn 104b and the terminal 114a, and the conductive yarn 104b and the terminal 114a are electrically connected to each other by the eyelet 108. For the eyelet 108, a conductive metal material (eg, copper, aluminum, etc.) is used. For this reason, the conductive yarn 104 and the terminal 114 can be electrically connected to each other via the eyelet 108.

[Method of connecting terminal 114 and conductive yarn 104]
FIG. 3 is a flowchart showing a procedure of a connection method according to an embodiment of the present invention. FIG. 4 is an explanatory view schematically showing a procedure of a connection method according to an embodiment of the present invention. FIG. 5 is an enlarged cross-sectional view illustrating a state of a connection portion of the LED circuit 110 according to the embodiment of the present invention. FIG. 5A shows a state where the eyelet 108 does not penetrate the conductive yarn 104 and the terminal 114. FIG. 5B shows a state where the eyelet 108 penetrates the conductive yarn 104 and the terminal 114. FIG. 5C shows a state where the eyelet 108 penetrating the conductive yarn 104 and the terminal 114 is crimped. Hereinafter, the procedure of a connection method (a method of connecting the terminal 114 and the conductive yarn 104) according to an embodiment of the present invention will be described according to the procedure shown in FIG.

(Step S302: Positioning process)
First, the terminal 114 of the LED circuit 110 is aligned with the conductive yarn 104 to be connected. For example, the terminal 114 and the conductive thread 104 are aligned with each other by adjusting the position and orientation of the LED circuit 110 on the surface of the ribbon 102. Here, in the LED circuit 110, a circular through hole 112a that penetrates the substrate 112 and the terminal 114 is formed in advance so that the eyelet 108 can penetrate the substrate 112 and the terminal 114 (see FIG. 5A). . Therefore, in this step, as shown in FIG. 5A, the center of the through hole 112 a is aligned with the center of the conductive yarn 104 on the surface of the ribbon 102. Thereby, the penetration in the through-hole 112a of eyelet 108 can be smoothly performed in the penetration process mentioned below.

(Step S304: Penetration process)
Next, the eyelet 108 is passed through the terminal 114 and the conductive yarn 104 that are aligned with each other. 4A to 4C show specific examples of a method of penetrating the eyelet 108 using the tool 400. FIG. As shown in FIG. 4A, the eyelet 108 has a cylindrical portion 108a and a flange 108b formed at the rear end of the cylindrical portion 108a. The flange 108b is a flat surface portion that is enlarged outward from the outer peripheral surface of the cylindrical portion 108a. The tool 400 has a round bar-shaped part 410 with a sharp tip. The diameter of the rod-shaped portion 410 is slightly smaller than the inner diameter of the cylindrical portion 108 a of the eyelet 108.

  First, as shown in FIG. 4A, the rod-shaped portion 410 of the tool 400 is inserted into the cylinder of the cylindrical portion 108a of the eyelet 108 from the flange 108 side. As a result, as shown in FIG. 4B, the eyelet 108 is attached to the rod-like portion 410 of the tool 400.

  Then, as shown in FIG. 4C, the conductive thread 104 (ribbon 102) and the through hole 112a (substrate 112 and terminal 114) penetrate from the back side of the ribbon 102 through the rod-like portion 410 to which the eyelet 108 is attached. Let Thereafter, the bar-shaped portion 410 is extracted from the eyelet 108. Thus, the cylindrical portion 108a of the eyelet 108 can be fitted into the through hole 112a in a state where the eyelet 108 penetrates the conductive yarn 104 (ribbon 102) and the through hole 112a (substrate 112 and terminal 114) (FIG. 5). (See (b)).

  In this step, it is preferable to pass the eyelet 108 through the center of the conductive yarn 104 as shown in FIG. As a result, the contact area between the eyelet 108 and the conductive yarn 104 can be increased. Therefore, contact failure between the eyelet 108 and the conductive yarn 104 can be prevented.

(Step S306: connection process)
Then, the terminal 108 and the conductive yarn 104 are slidably connected to each other by caulking the eyelet 108 that has penetrated the terminal 114 and the conductive yarn 104. 4D and 4E show specific examples of a method for caulking the eyelet 108 using the caulking tool 500. FIG.

  As shown in FIG. 4 (d), the eyelet 108 penetrates the conductive yarn 104 (ribbon 102) and the through hole 112a (the substrate 112 and the terminal 114) as shown in FIG. 4 (d). By applying pressure from above to the cylindrical portion 108a of the eyelet 108 using 500, the eyelet 108 is caulked. The operation here is only to push down the pressing portion 502 of the caulking tool 500 downward manually or automatically.

  As a result, the tip of the cylindrical portion 108a of the eyelet 108 is changed from the state of protruding upward from the surface of the terminal 114 (see FIG. 5B) to the state of being crushed and bent outward on the surface of the terminal 114, A flange 108c (a planar portion enlarged outward from the outer peripheral surface of the cylindrical portion 108a) can be formed at the tip of the cylindrical portion 108a of the eyelet 108 (see FIGS. 4E and 5C).

  As a result, as shown in FIG. 5C, the ribbon 102 and the substrate 112 are pressed against each other between the flange 108b and the flange 108c of the eyelet 108, and the terminal 114 and the conductive yarn 104 are interposed via the eyelet 108. Connected to each other. In this state, the outer peripheral surface of the cylindrical portion 108 a of the eyelet 108 is in contact with the conductive yarn 104. Further, the flange 108 c of the eyelet 108 is in contact with the terminal 114. Therefore, the conductive thread 104 and the terminal 114 are in a state of being electrically connected to each other by the eyelet 108.

  Similarly, the above-described steps S302 to S306 are executed for each of the plurality of terminals 114 included in the LED circuit 110. Thereby, each of the plurality of terminals 114 can be connected to the conductive yarn 104 easily and reliably.

  As described above, according to the light emitting device 10 of the present embodiment, a simple operation is performed in which the eyelet 108 is passed through the terminal 114 and the conductive thread 104 that are aligned with each other and the eyelet 108 is caulked. Only the terminal 114 and the conductive yarn 104 can be connected to each other so as to be conductive.

  Further, according to the light emitting device 10 of the present embodiment, the terminal 114 and the conductive yarn 104 are connected to each other with a relatively strong strength by the eyelet 108. For this reason, the connection of the connection is not released, and a contact failure does not occur between the two. Therefore, according to the light emitting device 10 of the present embodiment, the LED circuit 110 can be easily and reliably connected to the conductive yarn 104.

  Further, according to the light emitting device 10 of the present embodiment, the LED circuit 110 is crimped to the surface of the ribbon 102 with relatively strong strength at the same time by connecting the plurality of terminals 114 to the conductive yarn 104 by the eyelet 108. The Rukoto. Accordingly, it is not necessary to separately perform an operation for fixing the LED circuit 110 to the ribbon 102 (for example, an operation of fixing with the adhesive). Therefore, the LED circuit 110 can be easily and reliably fixed to the ribbon 102.

  Further, in the light emitting device 10 of this embodiment, the interval between the two conductive yarns 104 adjacent to each other is equal to the interval between the terminal 114 a and the terminal 114 b of the LED circuit 110. For this reason, the light emitting device 10 of the present embodiment has the LED circuit 110 in addition to the conductive yarns 104b and 104c (the conductive yarns 104a and 104b and the conductive yarns 104c and 104d) as long as two conductive yarns 104 are adjacent to each other. It is possible to connect.

  Further, in the light emitting device 10 of the present embodiment, the interval between the two conductive yarns 104 adjacent to each other is constant in the longitudinal direction of the ribbon 102 (y-axis direction in the drawing). For this reason, the light emitting device 10 of the present embodiment can connect the LED circuit 110 to any location in the longitudinal direction of the ribbon 102 (y-axis direction in the drawing).

  Further, in the light emitting device 10 of the present embodiment, the constant current diode 118 makes the drive current of the LED 116 constant, so that the LED 116 can emit light with a predetermined luminance. For example, as shown in FIG. 1, when a plurality of LED circuits 110 are provided in the longitudinal direction of the ribbon 102, the resistance values of the conductive yarns 104 a to 104 d vary depending on the difference in distance from the power supply unit 150. For this reason, the amount of supplied current differs among the plurality of LED circuits 110. Therefore, in each LED circuit 110, the drive current of the LED 116 is made constant. Thereby, the brightness | luminance of several LED116 can be made equal.

[First Modification]
FIG. 6 is a partially enlarged view showing a first modification of the LED circuit 110 according to the present embodiment. In the LED circuit 110a shown in FIG. 6, the interval between the terminals 114a and 114b is enlarged in accordance with the interval between the conductive yarns 104a and 104d. That is, the interval between the terminals 114a and 114b is defined so that when one terminal 114 is aligned with the conductive thread 104a, the other terminal 114 is aligned with the conductive thread 104d.

  With this configuration, as shown in FIG. 6, the LED circuit 110a can connect one terminal 114 to the conductive thread 104a by the eyelet 108 and connect the other terminal 114 to the conductive thread 104d by the eyelet 108. It is possible. That is, the LED circuit 110a can cause the LED 116 to emit light by the power supplied via the conductive yarns 104a and 104d.

[Second Modification]
FIG. 7 is a partially enlarged view showing a second modification of the LED circuit 110 according to the present embodiment. The LED circuit 110b shown in FIG. The LED unit 700 includes three LEDs 116 (an LED 116R that emits red light, an LED 116G that emits green light, and an LED 116B that emits blue light). Accordingly, the LED unit 700 can synthesize and output three colors of light (red light, green light, and blue light) by causing the three LEDs 116 to emit light simultaneously. Moreover, the LED unit 700 can output monochromatic light (any one of red light, green light, and blue light) by causing only one LED 116 to emit light.

  Accordingly, the LED circuit 110b is provided with four terminals 114a to 114d. The terminal 114a is for the + electrode of the LED 116R and is connected to the conductive yarn 104a. The terminal 114b is for the + electrode of the LED 116G and is connected to the conductive yarn 104b. The terminal 114c is for the + electrode of the LED 116B and is connected to the conductive yarn 104c. The terminal 114d is for the negative electrodes of the LEDs 116R, G, and B, and is connected to the conductive yarn 104d. Each of the terminals 114a to 114d is aligned with the conductive yarn 104 to be connected.

  With such a configuration, in this modification, the luminance of each of the LEDs 116R, 116G, and 116B can be controlled by controlling the amount of current supplied to the terminals 114a to 114c. Therefore, the color of light output from the LED unit 700 can be variously changed.

[Third to fifth modifications]
FIG. 8 is a partially enlarged view showing a third modification of the LED circuit 110 according to the present embodiment. FIG. 9 is a partially enlarged view showing a fourth modification of the LED circuit 110 according to the present embodiment. FIG. 10 is a partially enlarged view showing a fifth modification of the LED circuit 110 according to the present embodiment.

  An LED circuit 110c shown in FIG. 8 is a modification of the LED circuit 110 shown in FIG. In the LED circuit 110c, a plurality of terminals 114a and 114b are provided on the surface of the substrate 112 (corresponding to a first surface in the claims). On the other hand, in the LED circuit 110c, the LED 116 and the constant current diode 118 are provided on the back surface of the substrate 112 (corresponding to the second surface in the claims). In the LED circuit 110c, the plurality of terminals 114a and 114b and the LED 116 are electrically connected to each other through a through hole 109 (corresponding to a conductive portion in the claims) penetrating the substrate 112.

  Moreover, the LED circuit 110d shown in FIG. 9 is a modification of the LED circuit 110a shown in FIG. In the LED circuit 110 d, a plurality of terminals 114 a and 114 b are provided on the surface of the substrate 112. On the other hand, in the LED circuit 110 d, the LED 116 and the constant current diode 118 are provided on the back surface of the substrate 112. In the LED circuit 110 d, the plurality of terminals 114 a and 114 b and the LED 116 are electrically connected to each other through a through hole 109 that penetrates the substrate 112.

  An LED circuit 110e shown in FIG. 10 is a modification of the LED circuit 110b shown in FIG. In the LED circuit 110 e, a plurality of terminals 114 a to 114 d are provided on the surface of the substrate 112. On the other hand, in the LED circuit 110 e, the LED unit 700 and the constant current diode 118 are provided on the back surface of the substrate 112. In the LED circuit 110e, the plurality of terminals 114a to 114d and the LED unit 700 are electrically connected to each other through a through hole 109 that penetrates the substrate 112.

  As a result, as shown in FIGS. 8B, 9B, and 10B, the LED circuits 110c to 110e have the back surface of the substrate 112 (the installation surface of the LED 116 or the LED unit 700) of the ribbon 102. It can be mounted on the surface of the ribbon 102 while facing the surface. By attaching the LED circuits 110c to 110e in this way, light emitted from the LED 116 or the LED unit 700 can be transmitted through the ribbon 102 and emitted from the back surface of the ribbon 102. For this reason, the ribbon 102 is transparent to the light emitted from the LED 116 or the LED unit 700. Thereby, the light emitted from the LED 116 or the LED unit 700 can be diffused by the ribbon 102 or the intensity can be reduced by the ribbon 102. Further, the LED circuits 110c to 110e can be configured not to protrude from the light emission surface of the ribbon 102.

  In any of the first to fifth modifications, the terminal 114 and the conductive yarn 104 are connected to each other by the eyelet 108 so as to be conductive. Therefore, the connection of the terminal 114 to the conductive yarn 104 can be performed easily and reliably.
