Abstract

A connector is provided that includes a cabinet connector at a cabinet that includes at least one of a power supply device and an information processing device and a device connector at a control object device to be controlled by at least one of the power supply device and the information processing device. The device connector may be separably coupled to the cabinet connector. The device connector may be movable along at least two of an X-axis and a Y-axis defining a plane parallel to a cross section of the cabinet connector and a Z-axis perpendicular to the cross section of the cabinet connector.

Claims

1. A laundry treatment apparatus comprising:

a cabinet having an input opening;

a laundry receptacle configured to store laundry received through the input opening;

a door including a door frame configured to open or close the input opening, a hinge unit configured to rotatably couple the door frame to the cabinet, and a control panel at the door frame to input a control command or to output control information;

a cabinet connector at the cabinet, the cabinet connector being configured to transmit and receive at least one of power and a control signal; and

a door connector separably coupled to the cabinet connector, the door connector being configured to couple the control panel to the cabinet connector,

wherein the door connector is movable along at least two of an X-axis and a Y-axis defining a plane parallel to a cross section of the cabinet connector and a Z-axis perpendicular to the cross section of the cabinet connector,

wherein the cabinet connector includes a cabinet terminal at the cabinet, the cabinet terminal to couple to at least one of a power supply device for supply of power and an information processing device for transmission/reception of a control signal, and

the door connector includes;

a connector body at the hinge unit, the connector body having a receiving recess; and

a panel terminal separably coupled to the cabinet terminal so as to couple the control panel to the cabinet terminal, the panel terminal to move in the receiving recess along at least two of the X-axis, the Y-axis and the Z-axis.

2. The apparatus according to claim 1, wherein the door connector includes:

a first support portion at the receiving recess to elastically support the panel terminal along the Z-axis; and

a second support portion at the receiving recess to support the panel terminal such that the panel terminal is movable along the X-axis or the Y-axis.

3. The apparatus according to claim 2, wherein the cabinet terminal is a socket;

and

the panel terminal is a plug.

4. The apparatus according to claim 2, wherein the door connector further includes a slope formed at an outer circumference of the connector body;

and

the cabinet connector includes;

a cabinet connector body at the cabinet, the cabinet connector body being configured to receive the cabinet terminal; and

a guide formed at the cabinet connector body to couple to the slope so as to guide the panel terminal to the cabinet terminal.

5. The apparatus according to claim 2, wherein the panel terminal includes:

a terminal body at the receiving recess;

a flange at each of both facing ends of the terminal body, and the flange to be supported by the first support portion and the second support portion; and

a terminal fastener at the terminal body to be separably coupled to the cabinet terminal, the terminal fastener to couple to the control panel via a wire.

6. The apparatus according to claim 5, wherein the first support portion includes:

a fixing portion to protrude from a bottom surface of the connector body toward the flange;

a bent portion to extend from a distal end of the fixing portion toward the bottom surface of the connector body; and

an extension portion to extend from a distal end of the bent portion toward the flange to support the flange.

7. The apparatus according to claim 5, wherein the connector body includes a flange guide to protrude from an inner circumference of the receiving recess toward the terminal body along the Z-axis in a depth direction of the receiving recess, and

the second support portion to protrude from the flange guide, and the second support portion has a flange receiving groove configured to receive an upper surface of the flange.

8. The apparatus according to claim 7, wherein the flange receiving groove has a width to allow the flange to be movable along the X-axis in the flange receiving groove, and

the flange receiving groove has a depth to allow the flange to be movable along the Y-axis in the flange receiving groove.

9. An apparatus comprising:

a cabinet having an input opening;

a door frame configured to open or close the input opening;

a hinge unit to rotatably couple the door frame to the cabinet;

a control panel at the door frame;

a cabinet connector at the cabinet to receive power from a power supply device or to transmit a control signal to a processing device; and

a door connector to couple to the cabinet connector, the door connector to couple the control panel to the cabinet connector,

wherein the door connector is movable along at least two of an X-axis and a Y-axis defining a plane parallel to a cross section of the cabinet connector and a Z-axis perpendicular to the cross section of the cabinet connector,

wherein the cabinet connector includes a cabinet terminal to couple to one of the power supply device and the processing device; and

the door connector includes;

a connector body at the hinge unit, the connector body having a receiving recess; and

a panel terminal to couple to the cabinet terminal to couple the control panel to the cabinet terminal, the panel terminal being movable in the receiving recess along at least two of the X-axis, the Y-axis and the Z-axis.

10. The apparatus according to claim 9, wherein the door connector includes:

a first support portion at the receiving recess to support the panel terminal along the Z-axis; and

a second support portion at the receiving recess to support the panel terminal such that the panel terminal is movable along the X-axis or the Y-axis.

11. The apparatus according to claim 10, wherein the door connector includes a slope at a circumference of the connector body;

and

the cabinet connector includes;

a cabinet connector body to receive the cabinet terminal; and

a guide to couple to the slope to guide the panel terminal to the cabinet terminal.

12. The apparatus according to claim 10, wherein the panel terminal includes:

a terminal body at the receiving recess;

a flange at each of both ends of the terminal body, and the flange to be supported by the first support portion and the second support portion; and

a terminal fastener to couple to the cabinet terminal, the terminal fastener to couple to the control panel via a wire.
