As shown in FIGS. 1 to 3, the cable 5 is arranged, for example, behind the ceiling. A plurality of cables 5 are arranged between the main power source and the plurality of electric components 3, electrically connect the main power source and the plurality of electric components 3, and transfer the electric power from the main power source to the plurality of electric components 3. Supply. On both ends of such a cable 5, a cable output unit 11 electrically connected to the cable 5 and a cable input unit 13 are provided.

As shown in FIG. 2, the cable output unit 11 is provided on one end side of the cable 5 and includes a female connector 27 having a female housing 23 and a female terminal 25. In the cable output portion 11, the female housing 23 is formed in a housing shape extending along the outer surface of the electric component 3 so as to have only the fitting portion 31 (see FIG. 3). Further, the female terminal 25 is electrically connected to the terminal portion of the cable 5 and is housed in the female housing 23. The female connector 27 as the cable output unit 11 is fitted to the male connector 21 as the component input unit 7. By this fitting, the female terminal 25 and the male terminal 19 come into contact with each other, and the cable 5 and the electric component 3 are electrically connected.

As shown in FIG. 3, the cable input portion 13 is provided on the other end side of the cable 5 and includes a male connector 21 having a male housing 17 and a male terminal 19. In the cable input portion 13, the male terminal 19 is electrically connected to the terminal portion of the cable 5 and is housed in the male housing 17. The male connector 21 as such a cable input unit 13 is fitted to the female connector 27 as the component output unit 9. By this fitting, the male terminal 19 and the female terminal 25 come into contact with each other, and the cable 5 and the electric component 3 are electrically connected.

In the electrical component wiring structure 1 configured in this way, first, the male connector 21 as the cable input portion 13 of the cable 5 is electrically connected to the main power supply. The connector of the main power supply is generally a female connector 27 in which the female terminal 25 is not exposed to the outside. Therefore, the operator does not come into contact with the female terminal 25 through which electricity from the main power source flows, and does not receive an electric shock.

Next, the female connector 27 as the cable output portion 11 of the cable 5 is fitted to the male connector 21 as the component input portion 7 of the electrical component 3. At this time, the cable output unit 11 through which electricity from the main power supply flows is a female connector 27 in which the female terminal 25 is not exposed to the outside. Therefore, the operator does not come into contact with the female terminal 25 through which electricity from the main power source flows, and does not receive an electric shock.

Next, the male connector 21 as the cable input unit 13 of the cable 5 is fitted to the female connector 27 as the component output unit 9 of the electrical component 3 electrically connected to the main power supply. At this time, the component output unit 9 through which electricity from the main power supply flows is a female connector 27 in which the female terminal 25 is not exposed to the outside. Therefore, the operator does not come into contact with the female terminal 25 through which electricity from the main power source flows, and does not receive an electric shock.

In this way, by making the component output unit 9 and the cable output unit 11 where electricity from the main power supply may flow into the female connector 27 in which the female terminal 25 is not exposed to the outside, the operator can use the female terminal 25. It is possible to prevent electric shock without contacting with. Further, since the electrical connection between the main power supply and the plurality of electric components 3 via the cable 5 is a connector connection, the wiring workability can be improved. In addition, the electrical component 3 and the cable 5 can be handled separately, and the packaging of the electrical component 3 does not become large as in the case where the electrical component 3 and the cable 5 are integrally provided. ..

Here, the fitting of the female connector 27 as the component output unit 9 and the male connector 21 as the cable input unit 13 is performed along the outer surface of the electrical component 3. Further, in the fitting of the female connector 27 and the male connector 21, the fitting portion 31 of the female housing 23 is fitted so as to be accommodated inside the male housing 17. Therefore, when the outer surface of the fitting portion 31 of the female housing 23 is in contact with the outer surface of the electrical component 3, the fitting portion 31 cannot be inserted into the male housing 17, and the female connector 27 and the male connector 21 cannot be inserted. Cannot fit with.

In order to fit the female connector 27 and the male connector 21, it is conceivable that the fitting portion 31 is projected from the outer surface of the electric component 3 and the fitting portion 31 is fitted in the male housing 17. However, in this fitting structure, the female connector 27 protrudes from the electric component 3, and the electric component 3 becomes large. Further, the female connector 27 protruding from the electric component 3 may interfere with the peripheral member, and the female connector 27 may be damaged.

On the other hand, in order to fit the female connector 27 and the male connector 21, a spacer or the like is interposed between the outer surface of the fitting portion 31 and the outer surface of the electric component 3, and the outer surface of the fitting portion 31 and the electric component 3 are fitted with a spacer or the like. It is conceivable to form a gap with the outer surface. However, in this fitting structure, it is necessary to fix the spacer or the like and the female connector 27, which increases the number of parts and the man-hours for fixing work.

Therefore, as described above, the female housing 23 of the component output unit 9 is formed of a fixing portion 29 fixed to the electrical component 3 and a member continuous with the fixing portion 29, and is formed in the male housing 17 of the cable input unit 13. It has a fitting portion 31 that can be fitted. Then, a gap S into which the male housing 17 of the cable input portion 13 can be inserted is formed between the outer surface of the electric component 3 and the outer surface of the fitting portion 31. This gap S is set to be equivalent to the wall thickness of the male housing 17. The gap S may be set so as to have a slight gap between the outer surface of the male housing 17 and the outer surface of the electric component 3 so as not to increase the fitting force due to friction or the like. In this case, it is preferable not to insert the cable 5 or the like into a slight gap.

By forming the gap S in this way, the female connector 27 and the male connector 21 can be fitted without causing the fitting portion 31 of the female housing 23 to project from the outer surface of the electrical component 3. Further, it is not necessary to use a separate member such as a spacer, and the number of parts and the work man-hours do not increase.

In such an electrical component wiring structure 1, the component input unit 7 and the cable input unit 13 are housed in a male housing 17 having an opening 15 and a male housed in the male housing 17 and arranged so as to project toward the opening 15. It consists of a male connector 21 having a terminal 19. Further, the component output unit 9 and the cable output unit 11 have a female housing 23 that can be fitted into the male housing 17 from the opening 15. Further, it is composed of a female connector 27 having a female terminal 25 housed in the female housing 23 and having a male terminal 19 inserted therein and electrically connected to the male terminal 19.

Therefore, by making the component output unit 9 and the cable output unit 11 where electricity from the main power supply may flow into the female connector 27 in which the female terminal 25 is not exposed to the outside, the operator can use the female terminal 25. It is possible to prevent electric shock without contacting with. Further, since the electrical connection between the main power supply and the plurality of electric components 3 via the cable 5 is a connector connection, the wiring workability can be improved. Therefore, in such an electric component wiring structure 1, wiring workability can be improved without electric shock.

Further, the female housing 23 of the component output unit 9 is formed of a fixing portion 29 fixed to the electrical component 3 and a member continuous with the fixing portion 29, and can be fitted into the male housing 17 of the cable input portion 13. It has a joint portion 31 and. A gap S into which the male housing 17 of the cable input portion 13 can be inserted is formed between the outer surface of the electric component 3 and the outer surface of the fitting portion 31.

Therefore, the female connector 27 and the male connector 21 can be fitted without projecting the fitting portion 31 of the female housing 23 from the outer surface of the electric component 3, thereby suppressing the increase in size of the electric component 3. Can be done. In addition, interference between the female connector 27 and peripheral members can be suppressed, and damage to the female connector 27 can be suppressed. Further, since the fixing portion 29 is formed of one member continuous with the fitting portion 31, the number of parts and the work man-hours do not increase.

Although the present embodiment has been described above, the present embodiment is not limited to these, and various modifications can be made within the scope of the gist of the present embodiment.

For example, the fitting of the connector is performed in the direction along the outer surface of the electric component, but the fitting is not limited to this, and the fitting of the connector may be performed in the direction close to the electric component.
