BEST MODE FOR CARRYING OUT THE INVENTION A connection structure for an electric device according to the present invention will be described below with reference to the drawings. 1 to 27 show a first embodiment of the present invention, which is an electric device.
This is an example of a lighting unit 1, and the lighting unit 1 is basically a wiring board 4 on which a base body 2 and an LED 3 which is a light emitting element attached to the base body 2 are mounted, as shown in FIGS. 1 to 5. And a translucent cover 5 that covers the LED 3 and is attached to the base body 2.

The base body 2 is an integrally molded product of synthetic resin and has a substantially elongated box shape. That is, the base body 2 includes a bottom plate portion 11 and a pair of long side surface portions 12 and a pair of short side surface portions 13 that rise substantially vertically from the peripheral portion of the bottom surface portion 11.
And has an opening 14 on the upper side opposite to the bottom plate 11.

A notch 16 is formed in the center of the upper edge of each of the long side surfaces 12, and projecting substrate holders 17 and 18 are provided at both ends with the notch 16 in between. It is formed so as to integrally project. In particular, the protruding substrate holding portion 17 on one end side of the base body 2 has the same thickness as the side surface portions 12 and 13, and is relatively easily elastically displaceable. On the other hand, the protruding substrate holding portion 18 on the other end side of the base body 2
Slightly protrudes inward from the long side surface portion 12. And
Engaging claws 19 and 20 are integrally formed on the inner surfaces of the protruding substrate holding portions 17 and 18 that face each other at the tips thereof so as to integrally project. Engaging claw of the protruding substrate holder 17 on one end side of the base body 2
19 has a relatively small protrusion amount and is substantially triangular, and the engagement claw 20 of the protruding substrate holding portion 18 on the other end side of the base body 2 has a relatively large protrusion amount. There is. In addition, the bottom surface portion 11 of the base body 2 is formed with a through hole 21 or a notch portion 22 that includes the projected shape of the engaging claws 19 and 20 in a direction orthogonal to the bottom surface portion 11. Further, substantially triangular cover holding claws 23 are formed on the outer surfaces of the protruding substrate holding portions 17 and 18, respectively.

Further, the bottom surface portion 11 of the base body 2 has a substantially rectangular bolt through hole 26 at the end portion on the side of the protruding substrate holding portion 18.
Are formed. The bolt through hole 26 has a wide portion 26a on the center side in the longitudinal direction of the bottom surface portion 11 and a narrower portion 26b on the opposite side. The cutout portion 22 faces the narrow portion 26b. In addition, both long side parts 12
In between, an upper shield wall 27 facing the wide portion 26a, and a side shield wall hanging from one side edge of the upper shield wall 27 to the bottom surface portion 11
28 and 28 are formed integrally. The shield walls 27 and 28 shield the bolt through hole 26 from the inside of the base body 2. Further, the bottom portion 1 is continuous with the wide portion 26a.
A harness through hole 29 is formed from 1 through the shielding walls 27 and 28.

Further, substantially semicircular bolt through holes 31 are formed in the upper portions of both the short side surface portions 13. In addition, a pressing wall 33 having a semi-circular cutout portion 32 located coaxially with the bolt through hole 31 is provided at the end portion on the side of the protruding substrate holding portion 17 in the base body 2 and the bottom portion 11 and both. It is integrally formed along the short side surface portion 13. As a result, between the one short side surface portion 13 and the pressing wall 33 and the other short side surface portion
Fixing device built-in portions 34 are formed between 13 and the protruding substrate holding portion 18, respectively. Further, fixing projections 35 and 36 are formed on the outer surfaces of both the short side surface portions 13, respectively. Figure 20
As shown in FIG. 5, the fixing protrusions 35 and 36 of the two short side surface portions 13 are different from each other in radial distance from the central axis of the bolt through hole 31.

Further, on the inner surface of the bottom surface portion 11 of the base body 2, a pair of harness holding projections 37, which serve as wire holding portions,
38 is integrally formed vertically.

When the base body 2 is molded by means such as injection molding, a mold having a fixed mold and a movable mold that opens and closes in a direction orthogonal to the bottom surface portion 11 is used. With respect to the engaging claws 19 and 20 that may become, the through hole 21 and the notch 22 are formed at the corresponding positions on the bottom surface 11 to prevent the undercut shape. The same applies to the bolt through hole 26, the shielding walls 27 and 28, and the harness through hole 29. That is, the base body 2 has a shape that can be formed only by the fixed mold and the movable mold without using a slide core or the like, by appropriately setting the stationary and movable parting lines.

Is formed in a hook shape, and these hook-shaped harness holding protrusions 37, 38 can be integrally formed on the base body 2 only by the fixed type and the movable type, so that the bottom surface portion 11 of the base body 2 can be formed.
Through holes 37b, 38b are formed in the bottom of the harness holding projections 37, 38 in the direction orthogonal to the bottom surface 11 so as to include the projected shapes of the projections 37a, 38a. When the harness holding protrusions 37 and 38 are formed in a hook shape as shown in FIGS. 7 and 8, there is an advantage that the harness 51 described later can be held more reliably. On the other hand, as shown in FIGS. 1 and 2, when the harness holding protrusions 37, 38 are formed in a simple columnar shape, it is necessary to form the through holes 37b, 38b in the bottom surface portion 11 of the base body 2 for molding. There is an advantage that foreign matter can be suppressed from entering the lighting unit 1.

As shown in FIG. 9 and FIG. 10, the wiring board 4 has a substantially rectangular shape, and both long side surface portions of the base body 2.
The width is just enough to cover the 12 leading edges.
In addition, at the four corners of the wiring board 4, fixing notches which are fitted to the protruding board holding portions 17 and 18 of the base body 2, respectively.
41 and 42 are formed. Since the protruding substrate holders 17 and 18 at both ends of the base body 2 have mutually different widths, the fixing notches 41 and 42 at both ends of the wiring board 4 also have mutually different widths. Therefore, the wiring board 4 can be attached to the base body 2 only in a predetermined direction.
Further, notches 43 for harness passage are formed in the central portions on both sides of the wiring board 4, respectively.

A conductive pattern 46 is formed on the back surface of the wiring board 4. The conductive pattern 46 has a positive electrode portion 46a and a negative electrode portion 46b, which extend along both sides of the wiring board 4, respectively.

These electric wires 51a and 51b are connected to the wiring board 4 from the upper side. In addition, 1 is provided between the positive electrode portion 46a and the LED resistance connecting portion 46c.
The two LEDs 3 are connected, the resistor 52 is connected between the LED resistor connecting portion 46c and the resistor LED connecting portion 46d, and the resistor LE is connected.
A reverse connection preventing diode 53 is connected between the D connection portion 46d and the LED diode connection portion 46e, and another LED 3 is connected between the LED diode connection portion 46e and the negative electrode portion 46b. The electric wires 51a, 51b, the LED 3, the resistor 52 and the diode 53 are all on the wiring board 4 below (on the back side) thereof.
It is soldered in, which can reduce the cost. In particular, soldering the wires 51a and 51b on the lower side is
This is made possible by passing these electric wires 51a and 51b through the harness notch 43. In FIG. 5, 54 is a coupler connected to the tip of the harness 51.

FIG. 11 shows a circuit diagram of the wiring board 4. Electrically, the pair of diodes 3, the resistor 52, and the diode 53 are connected in series between the positive electrode 55 and the negative electrode 56.

The above-mentioned conductive pattern 46 is merely an example, and the conductive pattern can have various configurations. Although a jumper wire or the like can be used, it is more cost effective to adopt the configuration without using the jumper wire as in the above embodiment. Further, in this embodiment, two LEDs 3 are mounted on one wiring board 4, but the number of mounted LEDs 3 can be set appropriately.

For example, in FIG. 12, L in the wiring board 4 is shown.
Another example of mounting ED3, resistor 52 and diode 53 is shown. In this example, the harness passage notch 57 is formed only on one side of the wiring board 4, and both wires of the harness 51 are provided on both sides of the harness passage notch 57.
51a and 51b are respectively connected.

Further, FIGS. 18 and 19 show still another example of mounting the LED 3 and the resistor 52 on the wiring board 4.

The translucent cover 5 is made of a synthetic resin integrally molded, and has translucency such as milky white. The translucent cover 5 has a substantially box shape with one surface opened, and the opening side of the translucent cover 5 is fitted to the outside of the long side surface part 12 of the base body 2. It is part 61. Further, on both end surface portions of the fitting portion 61, concave portions 62 into which both the short side surface portions 13 of the base body 2 are fitted are formed. Further, substantially semicircular bolt through holes 63 are formed in these recesses 62, respectively. Also, the fitting part
Engagement holes 64 with which the cover holding claws 23 of the base body 2 are respectively engaged are formed on both side surfaces of 61. Further, a holding rib 65 is formed on each side surface of the end portion of the translucent cover 5. Further, a lens portion 66 including a plurality of R-shaped recesses is formed at the tip of the translucent cover 5.

Next, the assembly of the lighting unit 1 will be described. First, attachment of the wiring board 4 to the base body 2 will be described. The wiring board 4 has LEDs 3,
The resistor 52, the diode 53 and the harness 51 are connected in advance. Then, as shown by an arrow A in FIG. 17, first, one end portion of the wiring board 4 is provided with a pair of protruding substrate holding portions of the base body 2.
Insert between 18 under the engaging claw 20. Then, as shown by the arrow B in FIG. 17, the other end of the wiring board 4 is pressed against the base body 2 to be inserted between the pair of protruding board holding portions 17. Along with this, the wiring board 4 pushes the two protruding board holding portions.
17 is elastically displaced in the direction away from each other, and the wiring board 4
Rides over the engaging claw 19. Finally, the wiring board 4 is placed on the upper edges of both long side surface portions 12 of the base body 2, and the engaging claws 19 and 20 of the protruding board holding portions 17 and 18 are engaged with the wiring board 4 from above. By doing so, the vertical movement of the wiring board 4 with respect to the base body 2 is restricted. Further, the protrusion-shaped substrate holding portions 17 and 18 engage with the fixing notches 41 and 42 at the four corners of the wiring board 4, respectively, whereby movement of the wiring board 4 in the front-rear and left-right directions with respect to the base body 2 is restricted. It This allows
The wiring board 4 is securely fixed to the base body 2. Moreover,
No separate component such as a screw is required for mounting the wiring board 4.

Next, the wiring of the harness 51 when the wiring board 4 is mounted on the base body 2 will be described. Electric wire 5 connected to the positive electrode portion 46a of the wiring board 4
1a is led to the back side of the wiring board 4 through the harness passing notch 43 near the connecting portion 47, and the electric wire 51b connected to the negative electrode portion 46b is the harness passing notch near the connecting portion 47. It leads to the back side of wiring board 4 through 43. In particular, as shown in FIG. 13, the electric wires 51a and 51b are hooked around the harness holding projection 37 on the opposite side of the harness through hole 29 in the base body 2, and then around the other harness holding projection 38, and the harness is further bent.

The electric wires 51a and 51b are pushed by the wiring board 4 as the electric wires 51a and 51b are attached, and are attached to the harness holding projections 37 and 38 in the predetermined winding state.

Since the harness 51 is wound around the harness holding projections 37 and 38 as described above, even if the harness 51 is pulled outward, the tension is received by the harness holding projection 37, so that the wiring board 4 No direct load is applied to.

FIG. 14 shows another example of the wiring of the harness 51. In this example, the wiring board 4 shown in FIG.
In this case, both the electric wires 51a and 51b connected to one side of the wiring board 4 are inserted into one harness passing notch portion 57 of the wiring board 4 and hung around the harness holding projections 37 and 38. Then, it is led out of the base body 2 through the harness through hole 29. Even if a pulling load is applied to the harness 51, the tension is received by the harness holding projections 37, so that the wiring substrate 4 and the connecting portion between the wiring substrate 4 and the electric wires 51a and 51b can be protected against the pulling load. .

FIG. 15 shows an example in which the harness 51 is laterally extended. That is, this is an example in which the harness 51 is led out from the bolt through hole 31 of the one short side surface portion 11 of the base body 2. This can be utilized especially when a plurality of lighting units 1 are horizontally connected as described later. Even when the harness 51 is laid out sideways, the harness 51 is hung around the pair of harness holding protrusions 37 and 38, respectively.

Next, a structure for assembling the bolt 71 or the nut 72 for mounting the lighting unit 1 on the mounting portion will be described. The bolt 71 can be assembled to the base body 2 so as to project from the bottom surface portion 11 to the back side (lower side), or the bolt 71 can be assembled so as to project from the short side surface portion 13.

Basically, it has a pair of side plate portions 77 along the outer surfaces of both short side surface portions 13 of the base body 2, and a connecting portion 78 that connects these side plate portions 77. Then, the side plate 77 has a threaded portion 71b of the bolt 71.
Alternatively, through holes 80 through which the screws 79 are inserted are formed. As shown in FIG. 21, these through holes 80 have a diameter such that the fixing projections 35 and 36 on the outer surface of the base body 2 can be inserted therein. Further, as shown in FIG. 22, the material thickness t1 of the bracket 76 is, for example, 0.5 mm, whereas the protruding amount t2 of the fixing projections 35 and 36 is, for example, about 1 mm, which is larger than the material thickness of the bracket 76. The fixing protrusions 35 and 36 are configured to further project outward from the side plate portion 77 of the bracket 76. Further, the connecting portion 78 of the bracket 76 is formed with a through hole 81 through which the bolt 71 attached to the base body 2 while protruding from the bottom surface portion 11 thereof is inserted.

The lighting unit 1 can be used in various ways. This will be described below. The lighting unit 1 can of course be used alone, but FIG.
