Abstract

A connector includes: a card edge connector; a first cable drawn out from the card edge connector in a first direction; a first terminal disposed in the card edge connector and connected to the first cable; a receptacle into and from which the card edge connector is inserted and extracted; a second cable drawn out from the receptacle in a second direction; and a second terminal disposed in the receptacle and connected to the second cable. Insertion/extraction directions of the card edge connector are substantially perpendicular to at least one of the first direction and the second direction. The card edge connector includes a first end face which is substantially parallel to the insertion/extraction directions, and the receptacle includes a first wall face which is substantially parallel to the insertion/extraction directions. In a state where the card edge connector and the receptacle are coupled to each other, the first end face and the first wall face are in contact with each other.

Claims

1. A connector comprising:

a card edge connector;

a first cable which is drawn out from the card edge connector in a first direction;

a first terminal which is disposed in the card edge connector and which is connected to the first cable;

a receptacle into and from which the card edge connector is inserted and extracted;

a second cable which is drawn out from the receptacle in a second direction that is opposite or substantially opposite the first direction; and

a second terminal which is disposed in the receptacle and which is connected to the second cable,

wherein

when the card edge connector is inserted into the receptacle, the first terminal is electrically connected to the second terminal,

insertion/extraction directions of the card edge connector are substantially perpendicular to at least one of the first direction and the second direction,

the card edge connector includes a first end face which is substantially parallel to the insertion/extraction directions,

the receptacle includes a first wall face which is substantially parallel to the insertion/extraction directions, and

in a state where the card edge connector and the receptacle are coupled to each other, the first end face and the first wall face are in contact with each other so as to receive at least one of a pulling force of the first cable in the first direction and a pulling force of the second cable in the second direction, and wherein the pulling force of the first cable and the pulling force of the second cable are in opposing directions along substantially a same line.

2. The connector according to claim 1, wherein

the card edge connector includes a second end face which is substantially parallel to the insertion/extraction directions,

the receptacle includes a second wall face which is substantially parallel to the insertion/extraction directions, and

in the state where the card edge connector and the receptacle are coupled to each other, the second end face and the second wall face are in contact with each other so as to receive at least one of a pushing-in force of the first cable in a direction opposite to the first direction and a pushing-in force of the second cable in a direction opposite to the second direction.

3. The connector according to claim 1, wherein

the card edge connector includes a third end face which is substantially perpendicular to the insertion/extraction directions,

the receptacle includes a third wall face which is substantially perpendicular to the insertion/extraction directions, and

in the state where the card edge connector and the receptacle are coupled to each other, the third end face and the third wall face are in contact with each other.

4. The connector according to claim 1, wherein

the card edge connector includes a fourth end face which is substantially parallel to the insertion/extraction directions,

the receptacle includes a fourth wall face which is substantially parallel to the insertion/extraction directions, and

in the state where the card edge connector and the receptacle are coupled to each other, the fourth end face and the fourth wall face are in contact with each other so as to receive at least one of a pushing-in force of the first cable in a direction opposite to the first direction and a pushing-in force of the second cable in a direction opposite to the second direction.

5. The connector according to claim 2, wherein

one of concave and convex portions which are fitted to each other in the state where the card edge connector and the receptacle are coupled to each other is formed in the second end face and the other of the concave and convex portions is formed in the second wall face.

6. The connector according to claim 1, wherein

the first terminal includes a terminal for current use and an extension terminal.

7. The connector according to claim 1, wherein

the first cable is formed by a wiring pattern of a flexible printed circuit board and is connected to a sensor,

the first terminal is formed by exposing the wiring pattern of the flexible printed circuit board in a tip end portion on an insertion side of the insertion/extraction directions of the card edge connector, and

the card edge connector is formed by the flexible printed circuit board and a reinforcing plate which are overlaid and bonded with each other.

8. The connector according to claim 1, wherein

with respect to a line which passes through a drawn-out portion of the second cable and which is perpendicular to the insertion/extraction directions, a drawn-out portion of the first cable is positioned on a side of the insertion direction of the card edge connector.

9. The connector according to claim 1, wherein

with respect to a line which passes through a drawn-out portion of the first cable and which is perpendicular to the insertion/extraction directions, a drawn-out portion of the second cable is positioned on a side of the extraction direction of the card edge connector.

10. A card edge connector to be used in the connector according to claim 1.

11. A sensor using the card edge connector according to claim 10.
