Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power interruption device used when retrofitting optional electric components to an automobile. Here, retrofitting means that a user or the like later attaches electrical components other than the existing electrical components, which are standard equipment to the automobile after factory shipment.

[0002]

2. Description of the Related Art Among such retrofitting options, those which are used temporarily in a vehicle cabin can secure a power supply using a cigarette lighter, but those which are installed outside the vehicle cabin or are permanently installed require the use of a cigarette lighter. Inappropriate, it is necessary to connect to the vehicle power supply by another means.
For example, when an optional electric corner pole is used by being mounted near a bumper, an interrupt connection is made in advance to a coupler of an existing electrical component wiring provided inside the instrument panel.

[0003]

In the case where the coupler is interrupted inside the instrument panel, a lot of trouble such as removing the instrument panel during connection work is required. Also, in the interrupt connection to the coupler, the interrupt coupler must be configured to match the coupler of the interrupt partner, so if the number of terminals in the coupler of the interrupt partner increases, the number of coupler terminals on the interrupt side will increase accordingly And the number of terminals is usually considerably large, so that the cost is high. Therefore, an object of the present invention is to make interrupt connection inexpensive and easy to operate.

In the following description, an electrical component to be retrofitted will be referred to as an interrupt electrical component, and an existing electrical component to be interrupt-connected will be referred to as an interrupted electrical component. Are connected to the power supply side as an interrupt circuit and an interrupted circuit, respectively.

[0005]

According to a first aspect of the present invention, a vehicle power supply interrupter is connected to an on-vehicle power supply via a fuse box provided in an engine room. In a power interruption device for interrupting connection of an electrical component for retrofit to an existing electrical component, a fuse box side connector to be attached to a fuse box instead of a fuse connecting between an electrical component of an interrupt partner and a power source, and And a fuse mounting part formed separately and connected and connected via a spacing holding wire, and the fuse counterpart fuse and the interrupt side fuse that are connected in parallel to the power supply side are attached to and detached from the fuse mounting part. Freely mounted, the interrupt partner fuse connects the power supply and the interrupt partner electrical equipment,
The interrupt side fuse connects a power supply and the retrofitting electrical component.

According to a second aspect of the present invention, in the first aspect, the interrupt partner fuse is a fuse which has been removed in advance when the fuse box side connector is attached to the fuse box.

According to a third aspect of the present invention, in the first aspect, a backflow preventing means for interrupting each current to the interrupt partner fuse and the interrupt side fuse when the fuse box side connector is reversely connected to the fuse box. Is provided.

According to a fourth aspect of the present invention, in the first aspect, an operation switch for controlling the retrofitting electrical component is provided, and the operation switch is provided near the driver's seat. And shared.

[0009]

According to the first aspect of the present invention, the fuse for connecting the electrical equipment on the other end of the fuse attached to the fuse box to the power supply is removed, and the connector for the fuse box is attached to the fuse box instead. Attach the fuse on the other side of the fuse and the fuse on the interrupt side so that they are connected in parallel to the power supply side, connect the fuse on the interrupt side with the electrical equipment on the interrupt side, and connect the fuse on the interrupt side with the electrical equipment for retrofitting. Connecting.

[0010] In this way, the electrical component for retrofitting can be interrupt-connected to the electrical component on the other side of the interrupt by the fuse box, and the fuses on the interrupting component side and the interrupt side are connected in parallel to the power supply. The current flowing through the electrical equipment on the other side of the interrupt and the current flowing through the electrical equipment on the other side of the interrupt are respectively equal to or less than the rated current of each fuse on the other side of the interrupt.

As described above, when the electrical components for retrofitting are interrupt-connected by the fuse box, the fuse box is originally designed to facilitate the work of replacing the fuse in the engine room. Unlike locations where it is relatively difficult to work, such as inside, interrupt connections can be made easily and quickly.

In addition, since the positional relationship between the fuse box side connector and the fuse mounting portion can be freely adjusted by deforming the separation holding conductor, it can be accommodated and accommodated in the internal space of the fuse box. In addition, since it is not necessary to wire the electrical components for retrofitting to the coupler in the instrument panel as in the past, it is not necessary to remove the instrument panel,
The work for interrupt connection is further facilitated, and the wiring can be shortened.

Furthermore, since the connector on the fuse box side is mounted on the fuse box instead of the fuse, the connection terminals need only be two poles on the power supply side and the load side, and have a multi-terminal structure as in a conventional interrupt coupler. It can be manufactured inexpensively because it does not require.

According to the second aspect of the present invention, the fuse which has been removed in advance when the fuse box side connector is attached to the fuse box is used as the interrupt partner fuse, so that there is no need to provide a special interrupt fuse. I'm done.

According to the third aspect, when the fuse box side connector is connected to the fuse box in the opposite direction, the interrupt side fuse is connected in series to the interrupt side fuse, and as a result, the interrupt side fuse is normally connected. The current on the interrupt side is added to the current flowing through the fuse, and the current flowing through the interrupt-side fuse may exceed its rating.However, the present invention is provided with a backflow prevention means, so that when the connection is made in such a reverse direction, Can also interrupt the current to each of the fuses on the other side and the interrupt side,
Problems at the time of incorrect connection can be prevented.

According to the fourth aspect of the present invention, since the operation switch of the electric component for retrofitting is shared with the operation switch of the electric component on the other side of the interruption near the driver's seat, it is possible to operate comfortably near the driver's seat. An operation switch dedicated to retrofitting electrical components is not required, the number of components can be reduced, and the structure of retrofitting electrical components can be simplified. In addition, since direct wiring from the retrofitting electrical components to the operation switch near the driver's seat can be eliminated, troublesome wiring work to the vehicle interior can be omitted.

This embodiment is an example in which the optional electric component for retrofitting is an electric corner pole.
As shown in FIG. 1, the electric corner pole 1 includes a light emitting section 2, a telescopic pole section 3 and a motor 4, and the motor 4 is mounted inside a corner of a front bumper 5 of the automobile. The light emitting section 2 is a section provided with a light source inside so as to be lit at night or the like, and the pole section 3 is expanded and contracted by a motor 4.

At the end of the front bumper 5 near the motor 4, a position light 6 serving as a parking light and a vehicle width light, which is one of the existing electric components, is connected, and its power supply is connected to a fuse box 7. Power is supplied from a battery 9 which is a vehicle-mounted power supply via the interrupt attachment 8 provided. The power source for driving the light emitting section 2 of the electric corner pole 1 and the motor 4 is also connected to the attachment 8 for interruption.
And from the battery 9 via the fuse box 7.

The position light 6 is turned on or off by a position light switch 11 configured as a handle switch or the like. The operation of the electric corner pole 1, that is, lighting of the light emitting unit 2 and extension of the pole unit 3 or turning off of the light emitting unit 2 and contraction of the pole unit 3 can be performed by a switch (not shown) disposed in the vehicle interior.
However, common operation can be performed using the position light switch 11 as described later. In addition, the code | symbol 1 in a figure
2 is another existing electrical component such as an ignition device, 13 is an engine room, 14 is a hood, and 15 is a handle.

FIG. 3 is a view showing in detail the inside of the fuse box 7 and the appearance of the attachment 8 for interruption.
In the fuse box 7, a position light fuse 16 for connecting the battery 9 and the position light 6 and a plurality of existing electrical component fuses 16a for connecting the battery 9 and other existing electrical components 12 are detachably mounted. (However, in this figure, the position light fuse 1
6 is shown in a removed state).

The fuse 16 for the position light and the fuse 16a for the existing electric component are standardized in the same external form, and the rated current is determined according to each purpose. It is mounted and mounted by inserting it into the mounting hole 30 of the fuse box 7.

The interrupting attachment 8 includes a fuse box side connector 17 mounted on the fuse box 7 and a fuse mounting portion 18 formed separately therefrom.
Are connected by a pair of separation holding conductors 19a and 19b, and a pair of connection terminals including a power supply connection terminal 20a and a load connection terminal 20b project from the fuse box side connector 17. I have.

The attachment 8 for interruption in the present embodiment is used by attaching it to the fuse box 7 instead of the fuse 16 for position light previously attached to the fuse box 7. By inserting the power-supply-side connection terminal 20a and the load-side connection terminal 20b into the inserted mounting holes 30, interruption connection to the fuse circuit of the position light 6 can be made.

The power supply side connection terminal 20a and the load side connection terminal 2
The shape and size of the pair 0b and the distance between the two members are determined by a pair of connection terminals 3 described later in the position light fuse 16.
1a and 31b, and the mounting holes 30 of the fuse box 7 are replaced with the position light fuses 16.
Can be plugged into.

The mounting area S of the fuse box side connector 17 indicated by a phantom line is the area of the portion overlapping the fuse box 7 at the time of mounting, and is substantially the same as the area of the similar portion of the position light fuse 16. As a result, it is possible to mount the fuse 16a on the fuse box 7 adjacent to the other existing electrical component fuse 16a.

The fuse mounting portion 18 is larger than the fuse box side connector 17 so that a plurality of fuses (two in this embodiment) can be mounted side by side. 7 is so large that it cannot be mounted because it interferes with another adjacent existing electrical component fuse 16a.

A pair of mounting holes 33 having the same structure as the mounting hole 30 of the fuse box 7 is opened and provided in a portion of the surface of the fuse mounting portion 18 where the position light fuse 16 is mounted. The position light fuse 16 is mounted by inserting the connection terminals 31a and 31b of the position light fuse 16 which has been removed in advance.

In the fuse mounting portion 18, the interrupt side fuse 26 is arranged in line with the position write fuse 16.
(This drawing shows a state in which the interrupt side fuse 26 has already been attached). The interrupt-side fuse 26 is provided between the power-supply-side separating wire 19a and the motorized corner pole 1, and can be attached in the same manner as the position light fuse 16. The number of interrupt-side fuses 26 in the fuse mounting section 18 can be arbitrarily increased or decreased according to the number of interrupt-connected fuses.

An interrupting conductor 27 forming a part of an interrupt circuit extends from the fuse mounting portion 18, and a connector 28 is provided at one end thereof. Here, a conductor 1a on the motorized corner pole 1 side (FIG. 2). Is connected to a connector (not shown).

The separation holding wires 19a and 19b may be any wires as long as the fuse box side connector 17 and the fuse mounting portion 18 can be electrically connected. A well-known insulated coated conductor having flexibility and self-retaining property enough to hold the fuse mounting portion 18 above the connector 17 on the fuse box side in a state where the fuse mounting portion 18 is bent into a predetermined shape in the fuse box 7. It is.

The position write fuse 16 is directly attached to the fuse box 7 when the interrupt attachment 8 is not interrupted.
By inserting a and 31b into the mounting holes 30 of the fuse box 7, the fuses are electrically connected to fuse terminals described later in the fuse box 7 so that the current flows to the position light 6 within a range not exceeding the rating of the position light fuse 16. It has become.

The position light fuse 16 includes a base 32 made of an insulating material into which a fusing portion inserted so as to melt and break when a current larger than the rated current flows, and both ends and one end of the fusing portion. A pair of connection terminals 31a and 31b that are connected by a portion and the other end of which protrudes from the base 32.
And has a size and a shape that can be inserted into the mounting hole 30 of the fuse box 7 or the mounting hole 33 of the attachment 8 for interruption.

The other existing electrical component fuse 16a to which the existing electrical component 12 is connected and the interrupt side fuse 2
6 have the same structure, and the allowable current amount of each fuse, that is, the rated current, is appropriately set according to the load level of the connected position light 6 and other existing electrical components 12 and the like. Displayed on the surface. Further, it is possible to arbitrarily form the known fuses 21 and the interrupt side fuses 26 in different structures.

Next, the internal structure of the interrupt attachment 8 will be described in more detail. As shown in FIG. 1, the fuse box 7 includes a plurality of fuse terminals 10 having a pair of a power supply side fuse terminal 10 a connected to the battery 9 and a load side fuse terminal 10 b connected to a load such as the existing electric component 12. . In one set of the fuse terminals 10, the load side fuse terminal 10 b is connected to the position light 6, and the interrupt attachment 8 or the position write fuse 16 is provided between the fuse terminal 10 and the power supply side fuse terminal 10 a. Are electrically connected.

That is, in the fuse terminal 10 connected to the position light 6, at the time of interrupt connection,
The power supply side connection terminal 20a and the load side connection terminal 20b of the interruption attachment 8 are electrically connected to the power supply side fuse terminal 10a and the load side fuse terminal 10b, respectively. When no interruption occurs, the connection terminals 31a and 31b of the position write fuse 16 are not connected. Are electrically connected to the power supply side fuse terminal 10a and the load side fuse terminal 10b, respectively.

The existing electrical component fuses 16a are also conductively connected between the power supply side fuse terminals 10a and the load side fuse terminals 10b of the other fuse terminals 10, respectively. Current is prevented from flowing beyond the rated current to other existing electrical components 12 connected to 10b.

A power supply side fuse terminal 24a and a load side fuse terminal 24b to which one ends of the separation holding conductors 19a and 19b are connected are built in the fuse mounting portion 18, and these terminals are connected to the fuse box 7 side in advance. After that, the connection terminals 31a and 31b of the position light fuse 16 attached to the fuse attachment portion 18 are inserted into the attachment holes 33 and are electrically connected.

The power-supply-side fuse terminal 24a, the load-side fuse terminal 24b, the position-write fuse 16, the separation holding conductor 19b, and the load-side connection terminal 20
The circuit including b constitutes an interrupted circuit A for supplying power to the position light 6 side.

An interrupt circuit B is further provided in the fuse mounting portion 18 in parallel with the interrupted circuit A.
The interrupt circuit B includes a power supply side fuse terminal 25a connected to the same polarity as the power supply side fuse terminal 24a of the interrupted side circuit A, a load side fuse terminal 25b paired with the power supply side fuse terminal 25a,
Interrupt-side fuse 26 for conducting connection between these two terminals
And an interrupting lead 27.

One end of the interrupting conductor 27 is connected to the fuse terminal 25b on the load side and extends from the fuse mounting portion 18, and the other end is connected to the power supply side of the electric corner pole 1, which is an electric component for retrofitting. The minus sides of the electric corner pole 1, the position light 6 and the other existing electrical components 12 are grounded.

Therefore, the power of the battery 9 is supplied to the fuse box 7, the fuse box side connector 17 of the interrupt attachment 8, and the fuse mounting portion 18 of the interrupt attachment 8 via the separation holding wire 19 a.
The power supply side fuse terminals 24a and 25a in the power supply are supplied to the interrupted side circuit A and the interrupt circuit B in parallel.

That is, the interrupt circuit A is connected to the position write fuse 1 from the power supply side fuse terminal 24a.
6, a current flows to the position light 6, and a current flows from the power supply side fuse terminal 25a to the electric corner pole 1 through the interrupt side fuse 26 to the interrupt circuit B. , Within the range of the rated current respectively defined for the position write fuse 16 and the interrupt side fuse 26 provided in parallel.

In the connector 17 on the fuse box side, the power supply side connection terminal 20a and one of the separation holding conductors 1 are provided.
A short circuit fuse 21 having the same structure as the position light fuse 16 is connected to one end of the lead 9a and a backflow preventing diode is connected between the load side connection terminal 20b and one end of the other separation holding conductor 19b. A surge current absorbing capacitor 23 is provided in parallel with the backflow prevention diode 22.

The conductor short-circuiting fuse 21 is for preventing a short circuit in the event of an accidental conduction between the separation holding conductors 19a and 19b, whereby the separation holding conductors 19a and 19b are connected to the fuse box side. Even when the connector 17 and the fuse mounting portion 18 are connected, the reliability can be improved. Moreover, the mounting area S of the fuse box side connector 17 does not need to be increased by mounting from the side.

The backflow prevention diode 22 constitutes the backflow prevention means in the present invention, and is provided by being inserted into an insulating resin constituting the fuse box side connector 17. It is not necessary to provide, for example, you may make it connect in the middle of the spacing | maintenance conductor 19b.

Next, the operation of this embodiment will be described. When the electric corner pole 1 is retrofitted, the electric corner pole 1 is attached to the front bumper 5 in advance, the motor 4 is housed inside the front bumper, and the conductor 1a of the electric corner pole 1 is wired into the engine room 13. I do.

Further, the hood 14 is opened, the fuse 16 for the position light attached to the position light of the fuse box 7 is pulled out, and the power supply side connection terminal of the connector 17 on the fuse box side constituting the attachment 8 for interruption is used instead. The interruption attachment 8 is attached to the fuse box 7 by inserting the load-side connection terminal 20b into the attachment hole 30.

Subsequently, the mounting hole 33 of the fuse mounting portion 18
The fuse 16 for the position light previously removed from the fuse box 7 is attached, and the fuse 26 on the interruption side is similarly attached to the attachment hole on the interruption circuit side. When a connector (not shown) provided on the side conductor 1a (FIG. 2) is connected, the interrupt connection of the electric corner pole 1 is completed.

At this time, the fuse box side connector 1
7, the mounting area S of the position light fuse 16 is substantially the same as that of the position light fuse 16.
6, an attachment 8 for interruption can be attached to the fuse box 7. In addition, since the fuse box 7 is originally designed to facilitate the replacement work of the position light fuse 16, the interruption is easily and quickly performed unlike a place where it is relatively difficult to work such as the inside of the conventional instrument panel. This makes it easier to retrofit this type of option.

Further, since the position light fuse 16 previously removed is mounted on the fuse mounting portion 18 of the interrupt attachment 8, the same fuse can be used for both the fuse box 7 and the fuse mounting portion 18. It is not necessary to prepare a special fuse for the device.

Further, since the electric corner pole 1 provided outside the vehicle compartment is connected to the fuse box 7 in the engine room 13, there is no need to wire the electric corner pole 1 to the coupler in the instrument panel. Since there is no need to remove and work, the work of interrupt connection is further facilitated, and the wiring can be shortened.

Further, the interrupt attachment 8 is connected to the power supply side connection terminal 20 a of the fuse box side connector 17.
And the load side connection terminal 20b alone and the power supply side fuse terminal 10a and the load side fuse terminal 10b of the fuse box 7.
Therefore, the number of terminals required for connection to the fuse box 7 is only required for these two poles, and a multi-terminal structure such as a conventional interrupt coupler is not required.

In addition, the separation holding conductors 19a, 19b
Has a flexibility and a self-retaining property, so that the fuse holding portion 18 is bent while bending the separation holding conductors 19a and 19b in accordance with the structure of the fuse box 7.
In this state, it can be held above the fuse box side connector 17 in this state.

As a result, it is possible to easily attach the interrupting attachment 8 into the fuse box 7 with good appearance. However, the holding of the fuse mounting portion 18 does not necessarily have to be performed only by the separation holding wires 19a and 19b. If necessary, the fuse mounting portion 18 is supported on the vehicle body side by appropriate means such as engagement or screwing. This allows for more reliable support.

Further, an attachment 8 for interruption is provided.
Since the reverse current prevention diode 22 is connected near the load side connection terminal 20b of the interrupted side circuit A, it is possible to prevent a problem when the reverse connection is incorrectly made.

That is, as shown in FIG. 4, the power supply side connection terminal 2 of the interrupt attachment 8 is connected at the time of interrupt connection.
0a and the load-side connection terminal 20b are erroneously connected to the load-side fuse terminal 10b and the power-supply-side fuse terminal 10a of the fuse box 7, respectively.
The interrupt circuit B is connected in series to the position write fuse 16, and there is a possibility that a current exceeding the rating flows to the position write fuse 16.

In such a case, however, the current is cut off between the power supply side fuse terminal 10a and the fuse terminal 24b of the fuse box 7 by the backflow prevention diode 22.
Since it is possible to prevent the fuse 16 for position light from being blown and to prevent an excessive current from flowing into the position light 6, it is possible to effectively prevent the occurrence of a malfunction at the time of incorrect connection.

FIG. 5 is a circuit diagram of another embodiment in which the operation switch of the electric corner pole 1 interrupted and connected as in the previous embodiment is shared with the position light 6. In this example, a plurality of interrupt attachments 8A, 8B and 8C are used to interrupt-connect the electric corner pole 1 and a controller 40 for controlling the corner pole.

That is, the interrupt attachment 8A is interrupted by one of the other existing electrical component fuses provided for the other existing electrical component 12 in the fuse box 7, and connected to the controller 40 via the interrupt side fuse 26a. Supply power to this.

Further, an interrupt attachment 8B is interrupt-connected to another existing electrical component fuse connecting the ignition switch 41 and the ignition circuit 42, and the controller 40 is turned on / off to the controller 40 via the interrupt side fuse 26b. Input a signal. In addition, position light switch 1
An interrupt attachment 8C is interrupted between 1 and the position light 6.

This interrupt attachment 8C has a three-circuit structure in which two interrupt-side fuses 26c and 26d can be attached in addition to the position write fuse 16, and the interrupt-side fuse 26c is connected to the controller 40 via the relay 43.

The relay 43 is a position light switch 1
In the present embodiment, the motor drive signal is input to the controller 40 when closed, in conjunction with the ON operation of 1 in this embodiment. However, it is of course possible to generate a drive signal when the relay 43 is opened as a normally closed type.

The interrupt side fuse 26 d is connected to the light emitting section 2 constituting the motorized corner pole 1 via the resistor R, and is turned on or off in conjunction with the position light 6. The light emitting section 2 of the present embodiment is configured by an LED.

The controller 40 is configured as a control device incorporating a logic circuit or a microcomputer or the like. The controller 40 is connected to both poles of the motor 4 constituting the electric corner pole 1 so as to be able to supply current in forward and reverse directions, and to operate an ignition switch. The drive of the motor 4 is controlled based on the operations of the position light switch 41 and the position light switch 11.

That is, when the ignition switch 41 is ON and a motor drive signal is input from the relay 43 every time the position light switch 11 is turned ON, the motor 4 is toggled forward or backward by this signal. When the ignition switch 41 is turned off when the pole section 3 is in the extended state, the motor 4 is reversed by the controller 40.

The controller 40 and the relay 43
Constitutes the corner pole control unit 44 together with the electric corner pole 1 and the position light switch 1
The electric corner pole 1 can be driven and controlled by using the 1 and the ignition switch 41 as a common operation switch.

Next, the operation of this embodiment will be described. First, when it is desired to use only the electric corner pole 1 without turning on the position light 6 such as in the daytime, when the position light switch 11 is turned on and off for a short time while the ignition switch 41 is on, the relay 43 is turned on. , A motor drive signal is input to the controller 40 via the controller 40. Based on this, the controller 40 rotates the motor 4 forward to extend the pole section 3.

When the position light switch 11 is turned on and off once again in a short time, the controller 40 reversely rotates the motor 4 based on the motor drive signal input again from the relay 43 to contract the pole portion 3.

When the electric corner pole 1 is used with the position light 6 turned on at night or the like,
When the position light switch 11 is turned on to turn on the position light 6, the relay 43 is closed at the same time and the motor drive signal is input to the controller 40. extend. At this time, the light emitting unit 2 is also turned on because electric power is supplied through the interrupt side fuse 26d.

Further, when it is desired to use only the electric corner pole 1 while keeping the position light 6 turned on, the position light switch 11 is turned off once and then turned on again. As a result, the relay 43 issues a motor drive signal, and the controller 40 rotates the motor 4 in the reverse direction to contract the pole portion 3. However, the position light 6 and the light emitting section 2 are turned off by the position light switch 11.
The light is turned off only for a short time when it is set to F, but the lighting state can be continued thereafter.

When the ignition switch 41 is turned off in the extended state of the pole section 3 regardless of whether the light emitting section 2 is turned on or off, the controller 40 causes the motor 4 to rotate in the reverse direction so that the pole section 3 contracts.

It is to be noted that, instead of the position light 6, the headlight can be linked with turning on or off, and in this case, the fuse connected to the switch circuit of the headlight is interrupted instead of the position light switch 11.

As described above, by using the plurality of interrupt attachments 8A to 8C and the multiple circuit interrupt attachments 8C, the corner pole control unit 44 can be easily interrupt-connected to the switch box 7, and the position light switch 11 and The ignition switch 41 can be used as a common operation switch.

For this reason, the number of switches can be reduced, and a dedicated switch for operating the electric corner pole 1 does not need to be provided in the vehicle interior. Since the work of wiring the wire harness can be omitted, the work of attaching and detaching the instrument panel and the like is also unnecessary, so that the mounting work can be reduced, the number of components can be reduced, and the apparatus can be inexpensive.

In addition, since the electric corner pole 1 can be controlled by a common switch at the same time as the position light 6 and the ignition circuit 42, the number of switches to be operated is reduced, so that the operability is improved. The structure of the electric corner pole 1, which is an electrical component, can be simplified.

Further, since the electric corner pole 1 can be operated by the position light switch 11 and the ignition switch 41 which are generally arranged near the driver's seat, the operation is further facilitated. In addition, since the light emitting unit 2 and the position light 6 having similar usage conditions can be simultaneously controlled by the same switch, the operability is also improved in this respect.

The present invention is not limited to the above-described embodiment, but can be modified in various ways. For example, the retrofitting electrical components and the existing electrical components are not limited to the motorized corner pole 1 and the position light 6 but may be various existing electrical components. Goods are possible.
