Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electric fender pole, and particularly aims to improve the electrical connection performance between the inner cable and the winding drum that winds the inner cable. This is about an electric fender pole.

[Background of the invention] The structure of the conventional electric fender pole is as follows.
There are structures as shown in FIGS. 5 to 10. This consists of a winding drum 2 that can be rotated forward or reverse by the driving force of a motor 1, a wire 3 whose one end is locked to the winding drum 2, and a wire 3 attached to the other end of the wire 3. , a telescoping fender pole 5 that expands and contracts on the bumper 4 by the movement of the wire 3, a pole case 6 that internally holds the fender pole 5, and a light emitting indicator light attached to the tip of the pole 5. 7
and an electric conductor 8 connected to the light-emitting indicator lamp 7 and inserted into the wire 3, and the connection between the drum side end of the wire 3 and the drum 2 is as follows: As shown in FIGS. 8 and 9, a wide diameter groove 10 is provided in a part of the wire storage groove 9 provided in the drum 2, and a conductive wire having a square-shaped side surface as shown in FIGS. The contact plate 11 is fixed with a mounting screw 12, and a conductive spherical contact member 13 is loosely fitted in the wide diameter groove 10 at the tip of the wire guided in the wire storage groove 9. are connected and fixed. The contact member 13 is electrically connected to the tip of the conductive wire 8 . Further, a pair of blade pieces 14 extending in the diametrical direction are formed on the pole case 6, and the pair of blade pieces 14 are passed through from above a notch 15 provided in the bumper 4, and then the pole case 6 is opened. After rotating approximately 90 degrees, bumper 4
The pole case 6 is attached to the bumper 4 by tightening the tightening screw 16 from the back side. Then, drive the motor 1 to move the drum 2 to the 8th drum.
When rotated in the arrow direction A in the figure, the pole 5
is pushed up and extended from the bumper, and at the same time, the contact member 13 comes into contact with the conductive contact plate 11, so that it is electrically connected to a power circuit (not shown), and the light emitting indicator lamp 7 lights up. On the contrary, if the motor 1 is driven and the drum is rotated in the direction opposite to the arrow direction A, the wire 3 is wound around the drum 2, the pole 5 is contracted, and the contact plate 11 and the contact member 13 are When the contact is removed, the light-emitting indicator lamp 7 is turned off.

However, in this conventional structure, the contact plate 1
1 and the contact plate 11 at the time of contact with the contact member 13
Since the contact surface is the edge corner of the contact plate 11 as shown in FIG. 8, the contact member 13 and the contact plate 1
The contact with contact member 1 is close to point contact, and the contact pressure is due to the rotating force of the drum.
3 and the contact plate 11 was unstable, resulting in a problem that the indicator light 7 would not turn on properly. Furthermore, since the contact plate 11 is fitted into the wire storage groove 9 formed in the drum 2, when the pole is extended in the rain, for example, the contact plate 11 is transmitted along the outer circumferential surface of the pole 5 and the circumferential surface of the wire 3. Therefore, rainwater may enter into the groove 9 of the drum 2, and as the rainwater flows in and accumulates in the groove 9, corrosion of the contact plate 11 and the contact member 13 occurs, resulting in poor contact. There were also problems that occurred.

[Purpose of invention]

The present invention has been made by focusing on such conventional problems, and in particular improves the contact performance between the contact plate and the spherical contact member, and provides an electric motor with a structure that can stably and ensure lighting of the indicator light. Our goal is to provide fender poles.
