Description

[Detailed Description of the Invention] The present invention relates to a device for attaching the conductor portion of a power supply wire in a device such as a vacuum cleaner, and its purpose is to simplify the connection of the power supply wire and prevent loss of tightening screws.

Conventionally, as shown in FIG. 1, a columnar terminal 102 is caulked to a rail 101, and a power supply wire 103 is connected to this so that it can be easily replaced when the conductor of a power supply wire of a device such as a vacuum cleaner is broken. The conductor portion 104 was connected by tightening the screw 105, but if the screw 105 was loosened too much when replacing the power supply wire 103, it often came off from the columnar terminal 102 and was lost.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a lower part of the main body, which is equipped with wheels 2 and 3 for transportation, an intake port 4 for connecting a hose to the front part, and a handle 5 for transportation, and a partition wall 6 is integrally formed inside. 7 is the upper part of the main body, 8 is the lower part of the main body 1
This is the back cover that is fixed with screws etc. Reference numeral 9 denotes a dust collection lid, which has a handle 10 at the front and a hook 11 at the rear, and closes the dust collection section of the lower part 1 of the main body. 1
2 is an electric blower, the front part is connected to the lower part 1 of the main body and the back cover 8 through the buffer bodies 13 and 14, and the rear part is connected to the holder 1.
5 is held in the lower part 1 of the main body. A power wire winding device 16 has a rotating shaft 17 fixed to a partition wall 18, rotates around the rotating shaft 17 in a space constituted by the partition wall 18 and a storage box 19, and winds the power wire 20 around the outer periphery. The storage box 19 is clamped and fixed between the main body upper part 7 and the main body lower part 1.

The power wire winding device 16 mainly includes a rotating drum 21 and a rail stand 22 that is detachably attached to the rotating drum 21. Inside the rail 23 of the current-carrying part is on the rail stand 22.
and the outer rail 24 are fixed by bending the claws 25. A conductive columnar terminal 27 for connecting a conductor portion 26 of a power supply wire 20 is caulked to the inside 23 and outside 24 of the rail. This columnar terminal 27 has an insertion hole 28 for the conductor portion 26,
Screw holes 30 for inserting terminal screws 29 are formed substantially orthogonally. Reference numeral 31 denotes a wall formed on the rail base 22, and is formed so as to come into contact with the head 32 of the terminal screw 30.

The conductor portion 26 of the power supply wire 20 is connected to the columnar terminal 2
7, insert the conductor portion 26 into the insertion hole 28 and tighten the terminal screw 29 to secure it. On the other hand, to remove it, simply loosen the terminal screw 29 and then pull out the conductor part 26, but at this time, the inside of the rail 23
Alternatively, the outer rail 24 deforms as shown by the dashed line in FIG.
1, the terminal screw 29 will not come off from the columnar terminal 27 and will not be lost.

According to the present invention as described above, by caulking the columnar terminal to the rail and bringing the head of the terminal screw into contact with the wall of the rail stand, there is no possibility of losing the terminal screw when replacing the power wire, and the terminal screw can be replaced easily. It has great practical value.
