Fitting structure of address unit of fire sensor
First Claim
1. A fire sensor comprising:
- a sensor base mounted and fixed on a predetermined position;
a sensor body including a plurality of pins, and a first fitting member for electrically and mechanically connecting said sensor body with said sensor base, said plurality of pins being formed on a surface of said sensor body and circumferentially arranged on a circle with a predetermined radius, said sensor base having a second fitting member which is electrically and mechanically fitted to said first fitting member; and
an address unit mounted on said sensor base, said address unit including a nonvolatile memory for electrically setting a readable address of said fire sensor, a first slide groove formed on a surface of said address unit along a path of rotational movement of said plurality of pins provided during mating of the address unit on the sensor base with the sensor body, and a plurality of connector members formed along said first slide groove, each of said pins passing through said connector members and electrically connecting to one of said connector members corresponding thereto upon said mating for electrically connecting the address unit and the sensor body to provide a signal path therebetween;
wherein said plurality of pins are received in said first slide groove, and said sensor body is rotated to fit said pins to said connector members, respectively, and said first fitting member to said second fitting member.

Abstract
A fire sensor according to the present invention includes a sensor base, a sensor body and an address unit. The sensor base is mounted and fixed on a predetermined position, for example, a ceiling. The sensor body includes a plurality of pins for electrically connecting the sensor body with the sensor base, and a first fitting member for electrically and mechanically connecting the sensor body with the sensor base. The plurality of pins are formed on a surface of the sensor body connectable to the sensor base and circumferentially arranged on a circle with a predetermined radius. The sensor base has a second fitting member which is electrically and mechanically fitted to the first fitting member. The address unit is mounted on the sensor base, and includes a nonvolatile memory for electrically setting a readable address of the fire sensor, a first slide groove formed along a path of rotation movement of the plurality of pins, and a plurality of connector members formed along the first slide groove, each of the pins passing through the connector members and electrically connecting to each of the connector corresponding thereto. The plurality of pins are inserted in substantially perpendicular into the first slide groove, and then the sensor body is rotated to fit the pins to the connector members, respectively, and the first fitting member to the second member.
