Abstract

Abstract An electrically conductive terminal having a connecting end and a mating end is affixed to a terminal assembly, the resultant subassembly placed within a housing containing a circuit board. The subassembly is located to effect electrical connection between the connecting end of the terminal and a pad on the circuit board, and to position the mating end externally to the volume to be potted. Connection between the terminal and the pad is reinforced by a solder flow technique. A potting material fills the housing encapsulating the circuit board and terminal assembly.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 93 words
A circuit potted within a housing unit wherein the improvement comprises a subassembly having a terminal and a terminal assembly, the terminal of electrically conductive material and having a connecting end and a mating end, the terminal affixed to the terminal assembly, the subassembly located in the housing via aligning means for positioning the connecting end within the potting material in electrical contating engagement with a selected portion of the circuit and a mating end external to the potting material, whereby electrical connection to the mating end effects electrical contact to the circuit.
Claim 2
Dependent Claim 93 words
A circuit potted within a housing unit wherein the improvement comprises a subassembly having a terminal and a terminal assembly, the terminal of electrically conductive material and having a connecting end and a mating end, the terminal affixed to the terminal assembly, the subassembly located in the housing via aligning means for positioning the connecting end within the potting material in electrical contating engagement with a selected portion of the circuit and a mating end external to the potting material, whereby electrical connection to the mating end effects electrical contact to the circuit.
Claim 3
Dependent Claim 34 words
The unit of claim 1 wherein the circuit includes electrical components affixed to conductors on a ceramic substrate, the substrate provided with conducting pads suitable for connection to the connecting end of the terminal.
Claim 4
Dependent Claim 14 words
The unit of claim 1 wherein the terminal assembly is potted within the housing.
Claim 5
Dependent Claim 15 words
The unit of claim 1 wherein the terminal is ultrasonically welded to the terminal assembly.
Claim 6
Dependent Claim 19 words
The unit of claim 2 wherein the connecting end is affixed to the pad via a solder flow technique.
Claim 7
Dependent Claim 15 words
The unit of claim 1 wherein a conductive member is soldered to the mating end.
Claim 8
Dependent Claim 22 words
The unit of claim 1 wherein the terminal is affixed to the subassembly prior to location of a subassembly within the housing.
Claim 9
Dependent Claim 26 words
The unit of claim 1 further comprising means to predeterminely locate and secure the circuit within the housing prior to locating the subassembly in the housing.
Claim 10
Independent Claim 117 words
A method of providing an electrical connection to a circuit located in a housing and potted therein including the steps of: a. locating the circuit within the housing, b. affixing a conductive terminal connector, having a connecting end and a mating end to a terminal assembly, resulting in a subassembly, c. locating the subassembly within the housing via aligning means for positioning the connecting end to be located within the potting material in contacting engagement with a selected portion of the circuit and positioning the mating end to be located without the potting material, d. forming an electrical connection between the connecting end and the circuit, and e. potting the circuit and terminal assembly in the housing.
Claim 11
Independent Claim 117 words
A method of providing an electrical connection to a circuit located in a housing and potted therein including the steps of: a. locating the circuit within the housing, b. affixing a conductive terminal connector, having a connecting end and a mating end to a terminal assembly, resulting in a subassembly, c. locating the subassembly within the housing via aligning means for positioning the connecting end to be located within the potting material in contacting engagement with a selected portion of the circuit and positioning the mating end to be located without the potting material, d. forming an electrical connection between the connecting end and the circuit, and e. potting the circuit and terminal assembly in the housing.
Claim 12
Dependent Claim 36 words
The method of claim 9 including the further steps of: a. constructing the circuit on the surface of a ceramic substrate, and b. providing a conductive pad on the substrate for connection to the connecting end.
Claim 13
Dependent Claim 18 words
The method of claim 9 wherein the affixing step further includes ultasonically welding the terminal to the subassembly.
Claim 14
Dependent Claim 26 words
The method of claim 10 wherein the forming step includes a. locating the connecting end to contact the pad, and b. solder flowing the ceramic surface.
Claim 15
Dependent Claim 17 words

Claim 16
Dependent Claim 64 words
The method of claim 9 wherein the step of locating the subassembly within the housing via aligning means comprises the steps of: a. providing mounting holes in predetermined locations in the subassembly; and b. forming studs in the housing, the studs adapted for engaging the mounting holes and guiding the subassembly to a predetermined location within the housing for proper register with the circuit.
Claim 17
Dependent Claim 63 words
The method of claim 9 wherein the step of locating the subassembly within the housing via aligning means comprises the step of: forming the subassembly of predetermined dimensions with respect to the housing such that when the subassembly is located within the housing it conforms to the housing walls for proper register of the terminal connector connecting end with the selected circuit portion.
Claim 18
Dependent Claim 64 words
The method of claim 14 wherein the step of locating the subassembly within the housing via aligning means comprises the further step of: forming the subassmbly of predetermined dimensions with respect to the housing such that when the subassembly is located within the housing it conforms to the housing walls for proper register of the terminal connector connecting end with the selected circuit portion.
