Abstract
Provided are circuit protection devices. In some embodiments, a protection device may include a set of leads extending though a socket body, wherein the socket body includes a first side opposite a second side, and a third side opposite a fourth side, wherein the third and fourth sides extend between the first and second sides, and wherein the third side includes a thermal vent. The protection device may further include a fusible element surrounding a central shaft, wherein the fusible element is connected with the set of leads.
Claims20
A protection device, comprising:
- a set of leads extending though a socket body, wherein the socket body comprises:
- a first side opposite a second side;
- and
- a third side opposite a fourth side, wherein the third and fourth sides extend between the first and second sides, wherein the third side includes a thermal vent, wherein the thermal vent comprises a first flat surface and a second flat surface recessed into the socket body, towards the fourth side, a first curved surface extending from the first flat surface, a second curved surface extending from the second flat surface, wherein the first and second curved surfaces are i-s-recessed farther into the socket body than the first and second flat surfaces, wherein the first and second curved surfaces are connected by a third flat surface, wherein the third flat surface is parallel to the first and second flat surfaces, and wherein the first and second flat surfaces are recessed farther into the socket body than the third flat surface;
- and
- a fusible element surrounding a central shaft, wherein the fusible element is connected with the set of leads.

A fusible device, comprising:
- a set of leads extending though a socket body, wherein the socket body comprises:
- a first side opposite a second side;
- and
- a third side opposite a fourth side, wherein the third and fourth sides extend between the first and second sides, wherein at least one of the third side and the fourth side includes a thermal vent, wherein the thermal vent comprises a first flat surface and a second flat surface recessed into the socket body, towards the fourth side, and a first curved surface extending from the first flat surface, a second curved surface extending from the second flat surface, and wherein the first and second curved surfaces are is recessed farther into the socket body than the first and second flat surfaces, wherein the first and second curved surfaces are connected by a third flat surface, wherein the third flat surface is parallel to the first and second flat surfaces, and wherein the first and second flat surfaces are recessed farther into the socket body than the third flat surface;
- and
- a fusible element wound about a central shaft, wherein the fusible element is electrically connected with the set of leads.
