Abstract

A protective sleeve structure for a proximity sensor contains a body made of non-magnetic material, and the body includes a fitting portion arranged on a first end thereof to fit with a sensing end of the proximate sensor, wherein an outer surface of the body is located at a non-sensing area of the proximity sensor, the body also includes a passageway defined on a second end thereof and located at a sensing area of the proximity sensor to pass an inducing element through the passageway, such that the inducing element triggers the proximity sensor. Accordingly, the protective sleeve structure stops metal substances attaching in the sensing area of the proximity sensor by using its body to avoid triggering the proximity sensor unintentionally. Preferably, the protective sleeve structure is simplified greatly and is manufactured easily.

Claims

1. A protective sleeve structure for a proximity sensor comprising a body made of non-magnetic material, and the body including:

a fitting portion arranged on a first end thereof to fit with a sensing end of a proximate sensor, wherein an outer surface of the body is located at a non-sensing area of the proximity sensor;

a passageway defined on a second end thereof and located at a sensing area of the proximity sensor to pass an inducing element through the passageway, such that the sensing end of the proximity sensor is triggered.

2. The protective sleeve structure for the proximity sensor as claimed in claim 1, wherein the body is injection molded from plastic material or rubber material.

3. The protective sleeve structure for the proximity sensor as claimed in claim 1, wherein the fitting portion is a recessed hole.

4. The protective sleeve structure for the proximity sensor as claimed in claim 3, wherein the fitting portion of the body matingly fits with the sensing end of the proximate sensor.

5. The protective sleeve structure for the proximity sensor as claimed in claim 1, wherein the passageway of the body is formed in a slot shape to pass through the inducing element.
