Abstract
Abstract A circuit assembly comprises a planar substrate 10 supporting, on a surface 11, connectors 14 and modules 12, the connector pieces of the connectors, and the module leads, both extending at least substantially parallel to said one major substrate surface, and the modules are clamped to the substrate in a readily releasable manner by means 40, so that a module can be replaced readily, for example, when faulty, and there may be a resilient part 48 of the clamping means between each module and a rigid part 41 of the clamping means, so that the module is not damaged by the clamping action; possibly the resilient part being provided by a composite structure of the resilient part and insulating sleeves 13' for module leads; and the clamping means including at least part of the connectors, so that the required clamping action is at least partially between the substrate and the connectors.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
214 words
A circuit assembly comprising an at least substantially planar substrate, on at least one major surface of which substrate is supported at least one component with leads extending therefrom, and there is also supported on said one major surface of the substrate at least one connector connected to said at least one component, the connector having a plurality of electrically conducting connector pieces, each connector piece extending parallel to and co-operating with a lead of the component, and providing a terminal of the circuit assembly, the plurality of connector pieces are secured to a block of electrical insulating material of the connector, and the arrangement is such that said at least one component is secured within the circuit assembly in a readily detachable manner by readily releasable clamping means provided in the circuit assembly, the required clamping action being between the substrate and the clamping means, the clamping means for said at least one component including at least part of the connector, the required clamping action being at least partially between the substrate and the connector by a cooperating flange and lip hyphen-shaped portion provided by the clamping means and the connector, the leads extending from said at least one component substantially in one plane parallel to said one major surface of the substrate.
Claim 2
Dependent Claim
214 words
A circuit assembly comprising an at least substantially planar substrate, on at least one major surface of which substrate is supported at least one component with leads extending therefrom, and there is also supported on said one major surface of the substrate at least one connector connected to said at least one component, the connector having a plurality of electrically conducting connector pieces, each connector piece extending parallel to and co-operating with a lead of the component, and providing a terminal of the circuit assembly, the plurality of connector pieces are secured to a block of electrical insulating material of the connector, and the arrangement is such that said at least one component is secured within the circuit assembly in a readily detachable manner by readily releasable clamping means provided in the circuit assembly, the required clamping action being between the substrate and the clamping means, the clamping means for said at least one component including at least part of the connector, the required clamping action being at least partially between the substrate and the connector by a cooperating flange and lip hyphen-shaped portion provided by the clamping means and the connector, the leads extending from said at least one component substantially in one plane parallel to said one major surface of the substrate.
