Abstract
An improved magnetic latching reed relay construction includes a hollow bobbin having an integrally formed flange and a base portion on each end. The bobbin is formed in one piece from a thermoplastic material. At least one reed switch is disposed within the bobbin. Mechanical support and electrical connections to the reed switch are provided by terminals disposed through each base portion so that they extend above the base portions. A plurality of terminals disposed through each base portion extend downwards therefrom to provide electrical connections to control coils wound about the bobbin.
Claims9
A reed relay comprising:
- an insulative bobbin having a longitudinal channel therein, a first circumferential flange formed at a first end of the bobbin, a second circumferential flange formed at a second end of the bobbin, a first base portion formed at the first circumferential flange, a second base portion formed at the second circumferential flange, and a circumferential spacer formed at the substantial midpoint of the bobbin, the circumferential spacer and the first circumferential flange serving to define a first coil receiving bobbin portion and the circumferential spacer and the second circumferential flange serving to define a second coil receiving bobbin portion;
- a first electrically conductive terminal disposed through the first base portion and extending from a first end at the top of the first base portion and from a second end at the bottom of the base portion;
- a second electrically conductive terminal disposed through the second base portion and extending from a first end at the top of the second base portion and extending from a second end at the bottom of the second base portion;
- an encapsulated reed switch disposed in the longitudinal channel having a first electrical lead connected to the first end of the first electrically conductive terminal and a second electrical lead connected to the first end of the second electrically conductive terminal;
- a plurality of coils wound about the bobbin including at least a first coil disposed about the first coil receiving bobbin portion;
- and
- means for connecting the coils.
A reed relay according to claim 2 wherein said means for connecting the coils includes a first plurality of terminals disposed through the first base portion and extending downward therefrom;
- and at least one third terminal disposed through the second base portion and extending downward therefrom.
A reed relay comprising:
- an insulative bobbin formed of a thermoplastic material having a longitudinal channel therein and including a first circumferential flange formed at a first end of the bobbin, a second circumferential flange formed at a second end of the bobbin, a first base portion formed at the first circumferential flange, a second base portion formed at the second circumferential flange, and a circumferential spacer formed at the substantial midpoint of the bobbin;
- an encapsulated reed switch disposed in the longitudinal channel having a first electrical lead extending over the first base portion and a second electrical lead extending over the second base portion;
- a first plurality of terminals disposed through the first base portion, each extending from one end at the bottom of the first base portion, and at least one of the first plurality of terminals extending from its other end at the top of the first base portion and connected to the first electrical lead;
- a second plurality of terminals disposed through the second base portion, each extending from one end at the bottom of the second base portion, and at least one of the second plurality of terminals extending from its other end at the top of the second base portion and connected to the second electrical lead;
- a plurality of control windings disposed about the bobbin, said control windings being connected to selected ones of the first and second plurality of terminals, and said plurality of control windings including a first winding disposed between the first circumferential flange and the circumferential spacer, and second and third windings disposed between the second circumferential flange and the circumferential spacer.
