Television receiver with provision for facilitating serviceability

Claim 2

In electronic apparatus including a cabinet having a front and back for enclosing an electronic chassis, with the chassis being slidably movable through an opening in the front of the cabinet from an operating position within the cabinet to a servicing position extending from the cabinet, and a powerline interlock for interconnecting a powerline cord terminal with the chassis in the operating position and disconnecting the chassis from the powerline cord terminal with the chassis in the servicing position, an improvement including in combination: powerline connector terminal means mounted on the rear of the movable chassis for connection to a powerline for supplying power to the chassis; powerline cord terminal means attached to the back of the cabinet for matingly conductively engaging the powerline connector terminal means on the rear of the chassis with the chassis in an operating position substantially abutting the cabinet back; and the cabinet back having an opening adjacent the powerline cord terminal means with said opening being closed by the rear of the chassis in said operating position, movement of the chassis to said servicing position disconnecting the connector terminal means from the powerline cord terminal means and unblocking the opening to permit attachment of a separate powerline cord to the line connector terminal means through the opening in the cabinet back without removing the cabinet back from the cabinet.

Claim 3

The combination according to claim 1 wherein the opening in the cabinet back is sufficient to permit the passage of a servicing powerline cord through the openings for connection to the powerline connector terminal means on the rear of the movable chassis with the movable chassis in the servicing position.

Claim 4

In a television receiver having a cabinet for enclosing a picture tube and an electronic chassis located alongside the picture tube, the cabinet having a back and having a front with a first opening for the picture tube and a second opening for a control panel mounted on the chassis, the chassis being slidably movable through the second opening in the front of the cabinet from an operating position within the cabinet to a servicing position extending from the front of the cabinet, an improvement including in combination: antenna terminal means mounted on the rear of the movable chassis and adapted for attachment to television antenna leads; powerline connector terminal means spaced from the antenna terminal means and mounted on the rear of the movable chassis for connection to a powerline for supplying power to the chassis; powerline cord terminal means attached to the back of the cabinet for matingly conductively engaging the powerline connector terminal means on the rear of the chassis with the chassis in said operating position substantially abutting the cabinet back; and the cabinet back having an opening opposite the antenna terminal means on the chassis, the opening being blocked by the rear of the movable chassis in the operating position while permitting access to the antenna terminal means, movement of the chassis to the servicing position disconnecting the powerline connector terminal means from the powerline cord terminal means, thereby unblocking the opening in the cabinet back and providing access to the powerline connector terminal means through the unblocked opening.

Claim 5

In a television receiver having a cabinet for enclosing a picture tube and an electronic chassis located alongside the picture tube, the cabinet having a back and having a front with a first opening for the picture tube and a second opening for a control panel mounted on the chassis, the chassis being slidably movable through the second opening in the front of the cabinet from an operating position within the cabinet to a servicing position extending from the front of the cabinet, an improvement including in combination: antenna terminal means mounted on the rear of the movable chassis and adapted for attachment to television antenna leads; powerline connector terminal means spaced from the antenna terminal means and mounted on the rear of the movable chassis for connection to a powerline for supplying power to the chassis; powerline cord terminal means attached to the back of the cabinet for matingly conductively engaging the powerline connector terminal means on the rear of the chassis with the chassis in said operating position substantially abutting the cabinet back; and the cabinet back having an opening opposite the antenna terminal means on the chassis, the opening being blocked by the rear of the movable chassis in the operating position while permitting access to the antenna terminal means, movement of the chassis to the servicing position disconnecting the powerline connector terminal means from the powerline cord terminal means, thereby unblocking the opening in the cabinet back and providing access to the powerline connector terminal means through the unblocked opening.

Claim 6

The combination according to claim 3 wherein the opening in the cabinet back has dimensions sufficient to permit the passage of the hand of a serviceman therethrough with the chassis in the servicing position to enable connection of a powerline cord to the powerline connector terminal means without necessitating removal of the back from the television receiver cabinet.

Claim 7

The combination according to claim 4 further including antenna leads connected with the antenna terminal means, with the length of the antenna leads being sufficient to permit movement of the chassis from the operating position to the servicing position drawing the antenna leads through the opening in the cabinet back.
