Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a connection for electrically connecting a main body of a power tool and a battery in a battery-type power tool such as a driver drill, an impact wrench, and a hammer drill. It is about equipment.

[Background of the Invention] Battery-operated power tools have no cord for supplying power to the main body, and therefore have high mobility in work at a high place or work in a narrow place, and have become widespread in the market mainly for driver drills and the like. However, in recent years, there has been an increasing need for these battery-powered tools to increase power, such as improving work speed and increasing the amount of work per charge, and the battery is inevitably becoming larger. For example, in the case of an impact wrench for bolt fastening, as shown in FIG. 2, a large battery weighing 600 g at a battery voltage of 12 V is attached to the main body of the impact wrench (hereinafter referred to as the main body). On the other hand, the weight of the power tool exceeds 2.5 kg, including the main body, and the total weight of the power tool is heavy. . On the other hand, a technique has been proposed in which the weight felt by the user during use is reduced to about 1.9 kg by separating the main body and the battery as shown in FIG.

However, since the configuration shown in FIG. 3 requires a power tool main body and a power supply unit dedicated to the main body, the configuration cannot be applied to a power tool conventionally used by a user. The versatility was poor.

[Purpose of the invention] The purpose of the invention is to reduce the weight felt by the user during use while taking advantage of the cordless power tool, and to provide a versatile power tool that can be used in conventional products. To provide.

[Summary of the Invention] The object is to provide a battery holster having a holster-side battery insertion port having the same shape as the main-body-side battery insertion port, and an adapter electrically connected to the battery holster. This is achieved by forming a shape corresponding to the battery insertion port.

[Embodiment of the invention] A state in which the battery holster 9 according to the invention is applied to a cordless impact wrench used for fastening a bolt or the like will be described with reference to FIG.

The cordless impact wrench includes a housing 1 containing a motor (not shown), a gear cover 2 containing a reduction mechanism and a striking mechanism, a switch 3 for turning on and off a power supply, and a handle 4 for holding a main body. Has a main body-side battery insertion port 5 and is held by a mounting latch 7 by inserting the plug portion 8 of the battery 6, so that the battery 6 and the main body of the impact wrench can be used with good mobility. The battery holster 9 includes a holster-side battery insertion port 10 capable of holding and connecting the battery 6 and a belt 11 for holding the battery holster 9 on a human body. The battery holster 9 can be connected to a main body via a cord 12. An adapter 14 is provided. The adapter 14 is provided with a plug 13 and a mounting latch 15 having the same shape as the battery 6, and can be easily attached and detached similarly to the battery 6. Therefore, by using the battery holster 9, the battery 6 can be used separately from the main body.

FIG. 4 shows a case where a plurality of batteries 6 can be attached to the battery holster 9, which can be used for a longer time.

Also, as shown in FIG. 5, the same effect as described above can be obtained by providing the power tool main body 16 with a jack 19 different from the main body side battery insertion port 5 and attaching the cord 12 of the battery holster 9 to the jack 19. be able to.

[Effects of the Invention] The present invention includes a holster having a holster-side battery insertion port having the same shape as the main-body-side battery insertion port, and an adapter electrically connected to the holster. By making the shape compatible with the mouth, while taking advantage of the cordless type power tool, the weight felt by the user at the time of use is reduced, and a versatile power tool that can be used with conventional products is provided can do.
