PROTECTOR WITH SENSOR AND METHOD OF MOLDING END PART OF THE SAME
First Claim
1. A protector with a sensor comprising:
- an installation base member operatively coupled on a peripheral edge of an opening/closing panel which moves between at least two positions to open and close an opening of an automobile body or on a peripheral edge of said opening of the automobile body, the opening/closing panel including a door and a sun roof of an automobile; and
a hollow part unified with the installation base member, the hollow part having two core wires and a space provided therein, the space being positioned between the two core wires;
said installation base member and said hollow part forming an extrusion molded part made of a rubber like elastic body which is extrusion molded, in which;
when an object is disposed between said opening/closing panel and said opening and makes contact with said hollow part when said opening/closing panel is moved towards a closed position, a corresponding change in electric signal detects said object; and
in a terminal part of said extrusion molded part, said core wires drawn out in a longitudinal direction are connected with two leads, said two leads being joined with a control unit or an electrical component, and a side of one end of an insert made of a non-conductive material is inserted in and fills up said space, and said terminal part of said extrusion molded part is die molded, wherein;
the terminal part of said extrusion molded part which is extrusion molded has a primary sealing layer and a secondary sealing layer formed thereon by means of injection molding respectively, said primary sealing layer covering wire connection parts of said core wires and said leads and a side of another end of said insert while also covering a ground part on a surface of said hollow part of the terminal part of said extrusion molded part, and said secondary sealing layer being piled on and covering the primary sealing layer, and said secondary sealing layer forming an external shape of a product.

Abstract
A protector with a sensor is installed on a sliding door for detecting an object by touch between two core wires in a hollow part. In a terminal part of the protector with the sensor, the core wires drawn out are connected with legs of a resistor. A primary seal is formed by grinding a surface of the hollow part of the terminal part of an extrusion molded part, positioning a ground part on a die and covering wire connection parts and a side of another end of an insert while also covering the ground part by means of injection molding. A secondary seal is formed by means of the injection molding for coating a part formed with the primary seal for forming an external shape of a product.
