Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical device configured with a housing divided into parts, which simplifies the wiring of the electrical circuit and facilitates the installation of parts.

In conventional electrical equipment, all electrical components are connected by soldering or the like using J-wires.

There are also devices that use printed wiring boards to remove lead wires, but even in these devices, electrical components are attached by methods such as soldering and caulking.

Accordingly, these methods increase the number of man-hours required for soldering, caulking, etc., and pose problems in terms of maintenance.

The present invention aims to eliminate these conventional drawbacks, simplify the assembly work, and facilitate the replacement of parts.

First, an embodiment of the present invention will be described based on the drawings.

FIG. 1 shows the present invention applied to a hair dryer.

Reference numeral 1 denotes a dryer housing formed into two parts in the vertical direction, and is made of synthetic resin.

This housing 1 is provided with an air discharge port 2 in the front direction and an air suction port 3 in the rear direction.

Reference numeral 4 denotes a groove provided in a predetermined pattern in the housing 1, and within this groove 4, a conductive wiring bar 5 made of a brass plate or the like is provided.

Each end of this wiring bar 5 has a protruding contact portion 6,
6 are integrally formed.

Switches 7 and 7 are indicated by dotted lines in FIG.
These are a motor with a fan 8 and a heat generating plate 9.

2 to 4 show each of these parts, each of which is provided with a recess 10 as a contact part that fits the contact parts 6, 6 of the wiring bar 5. It is.

The state in which these parts 7, 8, and 9 are fixed to the casing will be explained using FIG. 5 as an example of a motor with a fan.

First, the contact portion 6 of the wiring bar 5 provided at a predetermined position on the housing.
.

Thereafter, by tightening the cases together by a known means such as screw tightening, not only the motor 8 is fixed, but also the contact parts 6, 6 and the recess 10 of the motor 8 are completely fixed, and the electrical connection is completed.

Other parts can be electrically connected and fixed within the main body in the same manner.

Further, in order to achieve a complete electrical connection, the contact portions 6, 6 and the recess 10 may be constructed so as to have a wedge effect between them, and additional soldering may be performed as the case requires.

In the above description, the case is divided into two parts, but the case is not limited to this, and it may be divided into two or more parts depending on the configuration of the device.

Furthermore, the method of connecting the electric component and the wiring bar is not limited to the above embodiment, and the relationship between the concave and convex portions may be reversed, and the length of the protrusion may be appropriately selected to provide a positioning effect.

As explained above, in this invention, the electrical components themselves are provided with contact points, so the electrical connection of the components and fixation to the main body can be easily performed using the split casing without the need for special components. This makes it easier to replace parts during after-sales service, and also simplifies the number of manufacturing steps.
