Abstract
Abstract The present invention provides a crack-free electrical connection structure between electrical components and a circuit board in a connector device by soldering electrical wires to through-holes of the circuit board. Retention members (40) formed integrally with the connector device have slots (36) and channels (58, 62) intersecting inside the slots (36). Projections (54) are located at an exit of each channel (58). Ends of electrical wires (90) are stripped to expose core conductors (92) and they are bent in a generally L-shape to be disposed in the respective channels (58, 62) of slots 36. The projections (54) keep the exposed core conductors (92) in position, thereby simplifying electrical connection with through-holes in the circuit board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
An electrical connection structure for electrical components and for positioning exposed end portions of electrical wires of the electrical components for insertion into through-holes of a circuit board, comprising a housing having component-receiving areas along an upper surface for receiving the electrical components and holes through which the electrical wires of the electrical components extend; a wire-accommodation area along a bottom surface of the housing; and retention members extending outwardly from the bottom surface in which ends of the electrical wires are retained with the exposed end portions being oriented for insertion into the through-holes of the circuit board, wherein the retention members have a slot provided with a horizontal channel and a vertical channel so that the electrical wires retained therein assume an L-shape with the exposed end portions extending outwardly therefrom.
Claim 2
Dependent Claim
133 words
An electrical connection structure for electrical components and for positioning exposed end portions of electrical wires of the electrical components for insertion into through-holes of a circuit board, comprising a housing having component-receiving areas along an upper surface for receiving the electrical components and holes through which the electrical wires of the electrical components extend; a wire-accommodation area along a bottom surface of the housing; and retention members extending outwardly from the bottom surface in which ends of the electrical wires are retained with the exposed end portions being oriented for insertion into the through-holes of the circuit board, wherein the retention members have a slot provided with a horizontal channel and a vertical channel so that the electrical wires retained therein assume an L-shape with the exposed end portions extending outwardly therefrom.
Claim 3
Dependent Claim
41 words
An electrical connection structure as claimed in claim 1, wherein the vertical channel includes positioning projections between which the exposed end portions are disposed as they extend outwardly from the retention members and against which insulation of the electrical wires engage.
Claim 4
Dependent Claim
24 words
An electrical connection structure as claimed in claim 1, wherein board-mounting members extend outwardly from the bottom surface for mounting the circuit board thereon.
Claim 5
Dependent Claim
23 words
An electrical connection structure as claimed in claim 1, wherein posts extend outwardly from the upper surface for mounting a hold-down plate thereon.
Claim 6
Dependent Claim
27 words
An electrical connection structure as claimed in claim 1, wherein the housing has an extension on which an electrical connector having rows of electrical contacts is located.
Claim 7
Dependent Claim
34 words
An electrical connection structure as claimed in claim 1, wherein walls extend outwardly from the bottom surface surrounding the holes, and channels are located in the walls in which the electrical wires are positioned.
Claim 8
Dependent Claim
31 words
An electrical connection structure as claimed in claim 6, wherein clamp portions extend outwardly from the bottom surface between the walls and the retention members for clamping the electrical wires therein.
