Description

[Detailed Description of the Invention] The present invention relates to a coupler structure used to connect a power cord to a main body of a small portable electric appliance, particularly an electric shaver, etc., which is held in hand and used while moving.

Conventionally, most of the coupler structures for these small portable electrical devices are shown in FIG. The connector 4 on the power cord side is provided with an insertion hole 5 around which the pin 3 of the inlet is inserted and connected with conductivity.

With this coupler structure, when connecting a small portable electrical device such as an electric shaver, the cord is connected to the main body.
The problem is moving the code.

In other words, as shown in FIG. 2, the cord 6 of the connector connected to the inlet of the main body 5 of the small portable electric device is forced to move as shown by the arrow 7 due to the movement of the main body 1, and bends as shown by the dotted line. becomes.

For this reason, when used for a long period of time, the cord may be cut at the bent portion, making it impossible to conduct electricity, and in conventional coupler structures such as this, these problems occurred quite frequently.

The present invention eliminates the above-mentioned drawbacks and provides an ideal structure as a coupler for small portable electric devices, especially electric shavers, which are held in the hand and used on the move.
A detailed explanation will be given next.

FIG. 3 is a cross-sectional view of an embodiment of the present invention, in which a concave groove 8 is provided in the main body 7, and at opposing positions on both sides of the groove 8, the tip is biased inward by the spring force of a spring 9. A spherical pin 10 is provided, and the tips of the pin 10 protrude an appropriate amount from both concave side walls to form an inlet part.

The spring 9 and pin 10 are made of electrical conductors, and a lead wire 11 is electrically connected to the spring 9 to supply power to the internal circuit of the main body.

Also, the pins 1 protruding from both side walls of this concave groove 8
A connector 12 is provided with a recess 11 at a position where it engages with the connector 1.

A connector terminal 13 made of a conductor is provided in the recess 11 of the connector at a position where it contacts the pin 10 of the inlet, and the connector terminal 13 and the power cord 14 are electrically connected and insulated. The connector 12 is formed by molding the material.

In the coupler having the structure explained above, the arrow 15 in FIG.
Move the connector in the direction of and join the inlet and connector.

At this time, when the pin 10 and the connector recess 11 engage, the pin and the connector terminal 13 come into contact and are electrically coupled.

At this time, the connector 12 is an electrical connection, i.e. pin 1
As shown by the arrow 16 in FIG.
There is no need to bend the cord, so there is no need to worry about the cord breaking, which was a drawback with conventional products.

Additionally, as a result, the rotation around the engagement part between the pin 10 and the connector terminal 13 is much smoother compared to the conventional method of operating the device while bending the cord. , which also has the advantage of improved operability.

What has been described above is one embodiment of the present invention,
It can be used for other applications.

As mentioned above, this invention is suitable for all small portable electric devices.
This effect is particularly enhanced when used in electric shavers and the like.
