Abstract
A reed relay wherein a glass-enclosed switch is inserted into a hollow bobbin and a hinged tab is swung upwardly to provide a support shoulder for a lead projecting through the large opening of the bobbin. A housing has an internal shoulder at each end, the shoulders being engageable respectively with a preformed shoulder at one end of the bobbin and the shoulder provided by the hinged tab at the other end of the bobbin to clamp the leads between the bobbin and the housing. During assembly the hinged tab is forced upwardly by tooling which also provides a support about which the switch leads are bent through an angle of 90.degree..
Claims12
A reed relay comprising,
- a hollow bobbin having a large opening at one end and a small opening at the other end, at least one switch enclosed in a glass envelope and having leads projecting from both ends, said switch being inserted into said bobbin with leads projecting through said openings,
- said small opening including a transverse shoulder upon which said projecting lead rests,
- said bobbin having a tab hinged across said large opening and adapted to swing up into position to provide a shoulder across said large opening upon which said projecting lead rests, said hinged tab thereby permitting a large opening for switch insertion while providing a lead supporting shoulder after said switch has been inserted into said bobbin,
- and a housing for said bobbin.
The method of making a reed relay assembled from a hollow bobbin having a tab hinged across one open end thereof, a switch having leads projecting from each end, and a housing having shoulders at each end, comprising the steps of:
- inserting a switch in said bobbin through said open end,
- swinging said tab across said open end to provide support for a projecting switch lead,
- bending said switch lead downwardly,
- applying said housing to said bobbin to clamp said switch lead between said housing shoulder and said tab.
