Abstract
Abstract A coil is wound about an elongated glass capsule of a reed switch and held between plastic tubes attached to each end of the capsule. The plastic tubes extend over the opposite ends of the capsule and may be glued or fitted thereon. Flanges extend outward from the tubes and the coil is then wrapped on the capsule where it is maintained in position by the flanges. Outward extensions of the tubes protect the leads of the reed switch and correct concentricity tolerances on the glass capsule allowing use of conventional coil winding apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
An improved coil and switch structure comprising in combination: a switch device encapsulated in a generally elongated housing, said switch device including lead means responsive to a change in magnetic field to make and break a circuit, first and second tube member means affixed to opposite ends of said housing, each of said tube member means including an extension with an opening for matched fit receipt of said end of said housing, flange means extending outward from said extension transverse to the longitudinal dimension of said elongated housing, a passage through said tube member means for a lead to the interior of said housing, and a coil wrapped on said housing and maintained thereon by said first and second tube member means.
Claim 2
Dependent Claim
122 words
An improved coil and switch structure comprising in combination: a switch device encapsulated in a generally elongated housing, said switch device including lead means responsive to a change in magnetic field to make and break a circuit, first and second tube member means affixed to opposite ends of said housing, each of said tube member means including an extension with an opening for matched fit receipt of said end of said housing, flange means extending outward from said extension transverse to the longitudinal dimension of said elongated housing, a passage through said tube member means for a lead to the interior of said housing, and a coil wrapped on said housing and maintained thereon by said first and second tube member means.
Claim 3
Dependent Claim
63 words
The improved structure of claim 1 wherein said first and second tube member means each include an additional extension outwardly from said flange means in the direction opposite said extension whereby said opposite extension serves to protect a lead from said housing as well as providing a support for cooperation with a coil winding machine as a coil is wound about said capsule.
Claim 4
Dependent Claim
29 words
The improved structure of claim 1, wherein said housing and first and second tube member means are substantially cylindrical, said switch device comprising a reed switch encapsulated in glass.
Claim 5
Dependent Claim
21 words
The improvement of claim 1 wherein said flange includes a radial slot for receipt of a lead wire from said coil.
Claim 6
Dependent Claim
21 words
The improvement of claim 1 wherein said first and second tube member means are adhered to said housing by an adhesive.
Claim 7
Dependent Claim
32 words
The improvement of claim 1 wherein said first and second tube member means are affixed to said capsule by utilizing a shrinkable plastic material for said extension on said tube member means.
Claim 8
Dependent Claim
83 words
A structure for use in combination with an encapsulated reed switch cooperative to hold a coil in a substantially fixed position on said reed switch, comprising, in combination: a pair of first extension members each of said first extensions connectible to opposite ends of said reed switch including a passage for receipt of one end of said housing and a flange extending at least partially about said extension member and cooperative with said coil to hold said coil on said encapsulated reed switch.
Claim 9
Dependent Claim
83 words
A structure for use in combination with an encapsulated reed switch cooperative to hold a coil in a substantially fixed position on said reed switch, comprising, in combination: a pair of first extension members each of said first extensions connectible to opposite ends of said reed switch including a passage for receipt of one end of said housing and a flange extending at least partially about said extension member and cooperative with said coil to hold said coil on said encapsulated reed switch.
Claim 10
Dependent Claim
47 words
The improved structure of claim 7 wherein each of said first extensions is connected to second extensions extending in the opposite direction from said first extension, each of said first and second connected extensions including a passageway through said extensions for a lead from said reed switch.
