JP2001088058A - Dripproof structure of power tool - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a dripproof structure of a power tool capable of providing a sufficient dripproof effect even when a plurality types of power cables of different outside diameters are used for an existing cable holder. SOLUTION: A dripproof member is provided between an outside diameter part of a power cable 3 connected to a body housing 1 of a power tool and an inside diameter part of the cable holder 3 holding the power cable 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a drip-proof structure for a power tool.

[0002]

2. Description of the Related Art Some power tools need to prevent water from entering the inside of a main body housing. A special power tool requiring such drip-proof is a power cord connected to the main body housing. It is necessary to prevent a gap from being generated between the outer diameter portion of the cord holder and the inner diameter portion of the cord holder holding the power cord.

[0003]

However, if one cord holder is to be shared in response to the use of several types of power cords having different outer diameters for different destinations, the outer diameter portion of the power cord and the cord are not used. Since a gap is formed between the holder and the inner diameter of the holder, a problem arises in that the holder cannot be used for a special power tool requiring drip-proof.

It is an object of the present invention to apply an existing cord holder to several types of power cords having different outer diameters.
An object of the present invention is to provide a drip-proof structure of an electric power tool capable of obtaining a sufficient drip-proof effect.

[0005]

In order to achieve the above-mentioned object, a drip-proof structure of a power tool according to the present invention comprises an outer diameter portion of a power cord connected to a main body housing and a cord holder for holding the power cord. It is characterized in that a drip-proof member is interposed between the inner diameter portion.

[0006]

An embodiment of the present invention will be described below with reference to FIG. In the power tool, the cord drawer has a two-part main body housing. As shown in FIG. 1, the power cord 3 is fixed to one of the two main body housings 1 by a fixing bracket 5 and two screws 6. Have been. A cord holder 2 made of an elastic member is accommodated in a cord holder accommodating portion 1 a formed in the main body housing 1, and a power cord 3 penetrates an inner diameter portion of the cord holder 2. A plug (not shown) is connected to one end of the power cord 3, and a switch (not shown) housed inside the main body housing 1 is connected to the other end. Further, an O-ring 4 as a drip-proof member is provided between an outer diameter portion of the power cord 3 and an inner diameter portion of the cord holder 2. The O-ring 4 is for eliminating a gap generated between the outer diameter portion of the power cord 3 and the inner diameter portion of the cord holder 2, and water enters the inside of the main housing 1 of the power tool from outside. To prevent The O-ring 4 to be used may be selected according to the outer diameter of the power cord 3.

Next, a method of installing the O-ring 4 between the outer diameter of the power cord 3 and the inner diameter of the cord holder 2 will be described. First, place the O
Install the ring 4. Next, one end of the power cord 3 connected to the switch unit is inserted into the inner diameter of the cord holder 2, and the tip of the cord holder 2 is moved to a position where the O-ring 4 is installed. When the cord holder 2 is further moved, the O-ring 4 is located between the inner diameter part of the cord holder 2 and the outer diameter part of the power cord 3 as shown in FIG.

Next, a method of fixing the cord holder 2 to the main housing will be described. After the O-ring 4 is installed on the outer diameter portion of the power cord 3 and the inner diameter portion of the cord holder 2, one end of the power cord 3 is attached while the cord holder 2 is accommodated in the cord holder-accommodating portion 1 a of the main housing 1. The power cord 3 is connected to the switch unit, and the power cord 3 is fixed to the main body housing 1 by the fixing bracket 5 and the two screws 6. The other two main body housings (not shown) are combined with the main body housing 1, and the code holder 2 is also housed in a code holder housing (not shown) formed in the other main body housing. In this state, if the two-part body housing is connected by screws (not shown) in the screw insertion holes 7, the cord holder 2 is fixed to the body housing of the power tool.

In the embodiment, the present invention has been described as applied to the main housing of the power tool. However, the present invention is not limited to this.
The same effect can be obtained even when applied to a main body housing such as an intermediate switch used with an electric tool.

[0010]

According to the present invention, since the drip-proof member is interposed between the outer diameter portion of the power cord and the inner diameter portion of the cord holder, several types of power cords having different outer diameters are provided in the existing cord holder. It is possible to apply
