Abstract

In a connector that includes a board connector mounted on a board and a cable connector attached to ends of both a shielded cable and a non-shielded cable and connected to the board connector, the cable connector includes contacts connected respectively to the core wires of the shielded cable and the non-shielded cable and a shield shell that surrounds only the contacts connected to the core wires of the shielded cable, and the board connector includes board contacts connected respectively to the contacts of the cable connector and a shield shell that surrounds only the board contacts connected to the contacts surrounded by the shield shell of the cable connector. The connector properly shields the contacts connected to the core wires of the shielded cable in both of the mutually connected connectors and makes it easy to perform impedance matching.

Claims

1. A connector comprising:

a board connector mounted on a board; and

a cable connector attached to ends of both a shielded cable and a non-shielded cable and connected to the board connector;

the cable connector comprising;

contacts connected respectively to core wires of the shielded cable and the non-shielded cable; and

a shield shell surrounding only the contacts connected to the core wires of the shielded cable;

the board connector comprising;

board contacts connected respectively to the contacts of the cable connector; and

a shield shell surrounding only the board contacts connected to the contacts surrounded by the shield shell.

2. A connector according to claim 1, further comprising a housing mounted on the board,

wherein the housing comprises:

a tubular part to which an insertion joint of the cable connector is coupled; and

a window which catches a projection on the cable connector; and

the housing guides the cable connector with respect to the board connector and prevents the cable connector from falling out.

3. A connector according to claim 1, further comprising a housing that is disposed at an opening of a case accommodating the board and that is mounted to the case,

wherein the housing comprises:

a tubular part to which an insertion joint of the cable connector is coupled; and

a window which catches a projection on the cable connector; and

the housing guides the cable connector with respect to the board connector and prevents the cable connector from falling out.

4. A connector according to claim 1, wherein the cable connector and the board connector are connected through a relay connector.

5. A connector according to claim 4,

wherein the relay connector comprises relay contacts, a rear case, and a housing;

the contacts and the board contacts are connected through the relay contacts;

the rear case is disposed at an the opening of a case accommodating the board and is mounted to the case; and

the housing comprises a tubular part to which the insertion joint of the cable connector is coupled and a window which catches a projection on the cable connector and is secured onto the rear case.

6. A connector according to claim 5,

wherein the relay contacts project from the inner bottom of the tubular part, and

the inner bottom of the tubular part is sealed with resin.

7. A connector according to claim 2, wherein the back end of the cable connector from which the shielded cable and the non-shielded cable are led out and the insertion joint are surrounded by respective waterproofing members.

8. A connector according to claim 3, wherein the back end of the cable connector from which the shielded cable and the non-shielded cable are led out and the insertion joint are surrounded by respective waterproofing members.

9. A connector according to claim 5, wherein the back end of the cable connector from which the shielded cable and the non-shielded cable are led out and the insertion joint are surrounded by respective waterproofing members.

10. A connector according to claim 6, wherein the back end of the cable connector from which the shielded cable and the non-shielded cable are led out and the insertion joint are surrounded by respective waterproofing members.

11. A connector according to one of claims 1 to 10, wherein the board connector is surface-mounted on the board.
