In addition, the first connector is coupled to the second connector provided in the wire connected to the electric component, and the PCB controls the electric component.

However, the connector mounting structure of the washing machine according to the related art configured as described above has a pushing force or a pulling force of the second connector when the second connector is mounted or removed from the first connector. There is a problem that the transfer is directly transmitted to the terminal pin, such that the terminal pin is bent, such as a breakage, thereby causing a malfunction or breakage of the PCB.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object thereof is to provide a connector mounting structure of a washing machine, which prevents the pins of the connector fitted into the PCB from being bent or broken.

Connector mounting structure of the washing machine according to the present invention for solving the above problems is a PCB with a pin insertion hole formed; A first connector provided in the terminal pin inserted into the pin insertion hole; A second connector coupled to the first connector and connected to an electric wire; And supporting means for supporting the first connector to the PCB so that external force is not transmitted to the terminal pin when the first connector and the second connector are mounted or removed.

Here, the support means includes a support rib protruding from the lower portion of the first connector, and a rib insertion hole formed in the PCB to insert the support rib.

The plurality of support ribs and the rib insertion holes are formed to be spaced apart from each other.

The first connector may include a PCB mounting portion provided with the terminal pin and a connector mounting portion for detaching the second connector, and the support ribs may be disposed at the lower portion of the PCB mounting portion in the same line as the detaching direction of the second connector. Is formed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 or 2, the washing machine according to the present invention includes a cabinet 50 forming an appearance, a tub 55 installed inside the cabinet 50 and receiving wash water, and the tub ( A drum 60 installed inside 55 to accommodate laundry, a motor 65 for rotating the drum 60, a detergent box 70 for storing detergent, and a water supply device for supplying laundry water ( 75) and a drainage device 80 for draining the wash water.

In addition, a top plate 90 is mounted on the cabinet 50.

In addition, a laundry input hole (h) is formed on the front surface of the cabinet (50) so that laundry is introduced into the drum (60), and a door (95) for opening and closing the laundry input hole (h) is rotatably mounted. do.

In addition, a control panel 100 for controlling and displaying the operation of the washing machine is mounted on the front upper side of the cabinet 50.

Some cutaway side views of the mounting structure are shown.

As shown in Figure 3 to 5, the connector mounting structure of the washing machine according to the present invention is mounted on the inside of the washing machine PCB 105 to control the electrical components of the washing machine, and the plurality of sandwiching the PCB 105 A first connector 115 having a terminal pin 110 provided at one side thereof, a second connector 125 coupled to the other side of the first connector 115 and connected with a wire 120 from the electric component, When the first connector 115 and the second connector 125 are mounted or removed, a pushing force p or a pulling force a of the second connector 125 is directly transmitted to the terminal pin 110. It comprises a support means 130 for supporting the first connector 115 to the PCB 105 so that it is prevented.

In addition, the PCB 105 is provided with a plurality of pin insertion holes 135 into which the plurality of terminal pins 110 are inserted.

The plurality of terminal pins 110 are bent downward from one side of the first connector 115.

The first connector 115 includes a PCB mounting portion 115a having the terminal pin 110 and a connector mounting portion 115b on which the second connector 125 is mounted.

The support means 130 includes a support rib 130a protruding from the bottom of the PCB mounting portion 115a and a rib insertion hole 130b formed in the PCB 105 so that the support rib 130b is inserted. Is done.

Here, the support means may be formed so that the support rib is protruded to the PCB, the rib insertion hole is recessed in the lower portion of the PCB mounting portion.

The support ribs 130 are spaced apart from each other in front of the terminal pin 110 of the lower portion of the PCB mounting portion 115a to protrude downward, and the rib insertion holes 130b are formed on the respective support ribs. A plurality is formed to correspond to 130a.

Here, the support ribs 130 form the same line as that of the detachable direction of the second connector 125 that is detached from the connector mounting portion 115b.

Hereinafter, the operation of the connector mounting structure of the washing machine according to the present invention configured as described above is as follows.

First, the plurality of terminal pins 110 formed in the PCB mounting portion 115a of the first connector 115 are inserted into the plurality of pin insertion holes 135 of the PCB 105, respectively. A plurality of support ribs (130a) protruding in the) is inserted into the plurality of rib insertion holes (130b), respectively.

Subsequently, the second connector 125 is inserted into and coupled to the connector mounting portion 115b of the first connector 115, and electrical components connected to the wire 120 are controlled by the PCB 105.

At this time, when the second connector 125 is mounted, the pushing force p of the second connector 125 is transmitted to the support rib 130 so that the first connector 115 moves toward the PCB 105. Since it prevents the movement, the terminal pin 110 is prevented from being damaged due to the movement of the first connector 115.

Likewise, when the second connector 125 is removed, the pulling force a from the second connector 125 is transmitted to the support rib 130 so that the first connector 115 is connected to the second connector 125. It prevents the movement in the direction, thereby preventing damage to the terminal pin 110 due to the movement of the first connector (115).

The connector mounting structure of the washing machine according to the present invention configured as described above is provided with a terminal pin is fixed to the first connector by a support rib inserted into the PCB to the first connector fitted to the PCB, the first connector Since the movement of the first connector due to the pushing force or the pulling force of the second connector is suppressed when the second connector is mounted or removed, the terminal pin is prevented from being bent or broken.

In addition, the connector mounting structure of the washing machine according to the present invention is prevented from damage to the terminal pin, there is an advantage to prevent the malfunction or breakage of the PCB.
