Abstract
Abstract A reed relay, the essential novelty of which resides in the provision of a novel and unique bobbin assembly, said assembly comprising a bobbin constructed of electrically insulating material and having a hollow, elongated central core with an outwardly extending circular flange at one end thereof and an enlarged cylindrical body portion at the opposite end, said enlarged body portion having a pair of spaced circumferentially extending recesses therein, each of said recesses having a further recessed portion extending through said enlarged body into communication with the exterior of said core, and a pair of spaced leads extending axially from outside said bobbin through said enlarged body into said recesses, said leads having inner portions bent outwardly with respect to said enlarged body, said outwardly bent portions being diametrically opposed from each other and each being adapted to receive one of the ends of a drive coil that is wound around said central core.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A reed relay bobbin constructed of electrically insulating material and comprising a hollow elongate central core, an outwardly extending marginal flange at one end of said core, an enlarged cylindrical body at the other end thereof, a pair of spaced circumferentially extending recesses in said body located intermediate the ends thereof, each of said recesses having a further recessed portion at one end thereof extending through said body and communicating with the exterior of said core, and a pair of spaced leads extending axially from outside said bobbin through said body into said recesses, one lead extending into one of said recesses and the other lead into the other of said recesses, the inner ends of said leads being bent so as to be positioned in said circumferentially extending recesses, one end of said bobbin having an opening of substantially the same size as the interior of said core, and the other end of said bobbin being substantially closed but having an opening therethrough of substantially smaller size than the interior of said core.
Claim 2
Dependent Claim
174 words
A reed relay bobbin constructed of electrically insulating material and comprising a hollow elongate central core, an outwardly extending marginal flange at one end of said core, an enlarged cylindrical body at the other end thereof, a pair of spaced circumferentially extending recesses in said body located intermediate the ends thereof, each of said recesses having a further recessed portion at one end thereof extending through said body and communicating with the exterior of said core, and a pair of spaced leads extending axially from outside said bobbin through said body into said recesses, one lead extending into one of said recesses and the other lead into the other of said recesses, the inner ends of said leads being bent so as to be positioned in said circumferentially extending recesses, one end of said bobbin having an opening of substantially the same size as the interior of said core, and the other end of said bobbin being substantially closed but having an opening therethrough of substantially smaller size than the interior of said core.
Claim 3
Dependent Claim
68 words
In combination with the bobbin of claim 1, an electrically conductive coil wound around said core, one end of said coil extending through one of said further recessed portions and making electrical connection with one of said lead inner portions, and the other end of said coil extending through the other of said further recessed portions and makiNg electrical contact with the other of said lead inner portions.
Claim 4
Dependent Claim
64 words
The combination of claim 2 further comprising an encapsulated reed switch having wire leads extending from opposite ends of the capsule, said reed switch being positioned within said hollow bobbin core with one of said wire leads extending outwardly through the open end of said bobbin and the other wire lead extending through said smaller opening at the substantially closed end of said bobbin.
Claim 5
Dependent Claim
67 words
The combination of claim 3 further comprising an outer cylindrical shell snugly receiving said bobbin therein, said shell having one open end positioned adjacent the substantially closed end of said bobbin, and a closed end positioned adjacent said bobbin open end, said closed shell end having an opening therethrough of substantially the same size and in general alignment with said smaller opening in said bobbin closed end.
Claim 6
Dependent Claim
20 words
In the combination of claim 5, said shell and said bobbin having cooperating detent means for insuring proper orientation therebetween.
Claim 7
Dependent Claim
25 words
In the combination of claim 2, said leads being bent in the same direction as the direction in which their respective coil end is wound.
