Abstract
A protector with a sensor is installed on a sliding door for detecting an alien substance 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 leads joined with a control unit, an insert fills up a space and the terminal part is die molded. Materials of the insert and the die molding material have compatibility with each other.
Claims7
A protector with a sensor comprising:
- an installation base member operatively coupled on a peripheral edge of an opening or closing object for opening or closing an opening of an automobile body, the opening or closing object including a door or a sun roof of an automobile, or on a peripheral edge of said opening;
- and a hollow part integrally molded 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, in which:
- when an alien substance caught between said opening or closing object and said opening presses and crushes said hollow part while closing said opening or closing object, a corresponding change in electric signal detects said alien substance;
- and
- in a terminal part, said core wires drawn out in a longitudinal direction are connected with leads, said leads being joined with a control unit or an electrical component, and one end side of an insert made of a non-conductive material is inserted in and fills up said space, and said terminal part is die molded, wherein:
- materials of said insert and said die molding material have compatibility with each other.
