Abstract
In some embodiments, an electrical device can include a body having a shape that extends along a longitudinal direction, and a set of electrodes implemented on the body at different locations along the longitudinal direction and configured to allow the electrical device to be positioned and mounted to a surface. The set of electrodes can include first and second electrodes configured to provide first and second engagements with the surface, respectively, and to allow a settling motion when the electrical device is positioned on the surface. The set of electrodes can further include a selected electrode having a side configured to allow the settling motion and an engagement portion configured to stop the settling motion and thereby provide a third engagement with the surface.
Claims19
An electrical device comprising:
- a body having a cylindrical shape with a radius and a longitudinal axis that extends along a longitudinal direction;
- and
- a set of electrodes implemented on the body at different locations along the longitudinal direction and configured to allow the electrical device to be positioned and mounted to a surface, the set of electrodes including first and second electrodes each having a circular perimeter with a radius greater than or equal to the radius of the cylindrical shaped body, the first and second electrodes configured to provide first and second engagements with the surface, respectively, the set of electrodes further including a selected electrode having a polygonal shaped perimeter with sides joined by corners, each side spaced from the longitudinal axis of the body by a dimension that is less than the radius of each of the first and second electrodes, each corner spaced from the longitudinal axis of the body by a dimension greater than the radius of each of the first and second electrodes, such that the selected electrode is configured to provide a third engagement with the surface.
A method for manufacturing an electrical device, the method comprising:
- providing or forming a body such that the body has a cylindrical shape with a radius and a longitudinal axis that extends along a longitudinal direction;
- and
- implementing a set of electrodes on the body at different locations along the longitudinal direction to allow the electrical device to be positioned and mounted to a surface, such that the set of electrodes includes first and second electrodes each having a circular perimeter with a radius greater than or equal to the radius of the cylindrical shaped body, the first and second electrodes configured to provide first and second engagements with the surface, respectively, the set of electrodes further including a selected electrode having a polygonal shaped perimeter with sides joined by corners, each side spaced from the longitudinal axis of the body by a dimension that is less than the radius of each of the first and second electrodes, each corner spaced from the longitudinal axis of the body by a dimension greater than the radius of each of the first and second electrodes, such that the selected electrode is configured to provide a third engagement with the surface.
A surface-mountable circuit protection device comprising:
- a first component implemented between a first end electrode and a middle electrode;
- and
- a second component implemented between the middle electrode and a second end electrode, such that the first and second components define a body having a cylindrical shape with a radius and a longitudinal axis that extends along a longitudinal direction, two of the first end, middle and second end electrodes configured to provide two engagements with a surface with each of the two electrodes having a circular perimeter with a radius greater than or equal to the radius of the cylindrical shaped body, the remaining one of the first end, middle and second end electrodes having a polygonal shaped perimeter with sides joined by corners, each side spaced from the longitudinal axis of the body by a dimension that is less than the radius of each of the two electrodes, each corner spaced from the longitudinal axis of the body by a dimension greater than the radius of each of the two electrodes, such that the remaining electrode is configured to provide a third engagement with the surface.
