Description

[0001] ELECTRIC HEATER [0002]

The present invention relates to an electric heating device, and more particularly, to a heat transfer device for heating which has a simple connection structure between electric wires and a heating member and has excellent water tightness to prevent moisture from penetrating.

1 is a schematic view showing a conventional heating apparatus for heating.

As shown in FIG. 1, the electric heating apparatus is installed on the floor of a house, a school, a factory, an airport runway, etc., and includes a plug P for receiving power, And a plurality of heating lines (2) connected in parallel to the two wires (1) and spaced apart at regular intervals. The connection portion between the electric wire and the heating wire is sealed by the connector (4).

The electric wire 1 is composed of a conductor 1a through which a current flows and a shell 1b surrounding the conductor. The heating wire 2 is composed of a heating body 2a and a shell 2b surrounding the heating body 2a. The electrical connection between the electric wire 1 and the heating wire 2 is made by peeling off the sheath 1b of the electric wire and connecting the exposed conductor 1a and the heating wire 2b of the heating wire to the conductive connector 3.

The conductor of the exposed wire for connection to the heating element and the heating element of the heating wire must be sealed by the connector to prevent contact with moisture so as not to cause electric safety problems such as electric leakage.

However, the conventional connector has such a problem that water tightness is not sufficiently ensured and it is exposed to electric safety accidents.

In this way, the conventional connector does not ensure watertightness, and moisture permeates into the inside of the connector because a conventional method in which the connector surrounds the connection portion between the electric wire and the heating wire is used to bond the adhesive to the inside of the connector, 1, a connector made of a synthetic resin is first wrapped around a connection part and then melted and bonded using ultrasonic waves or high frequency waves.

In the method using the adhesive, the adhesive has a limitation in sealing the inlet of the electric wire and the inlet of the heating wire of the connector, and the fusion bonding by the ultrasonic wave or the high frequency is difficult to completely bond the connector to the electric wire or the heating wire. The watertightness of the conventional connector is not ensured.
