Abstract

A vacuum cleaner of the present invention comprises: a main body having a suction motor for generating suction force; a main PCB capable of generating a control command for the suction motor; a handle part capable of accommodating the main body PCB; and a connector provided at the main body, and to which the main PCB is connected in a process of coupling the handle part to the main body. The main PCB includes a plurality of pads and a slit, and the connector includes: a plurality of connecting pins for making contact with the plurality of pads; and a slit insertion protrusion inserted into the slit.

First claim

The invention claimed is:

1. A cleaner comprising:
a main body comprising a suction motor configured to generate suction force;
a main Printed Circuit Board (PCB) configured to generate a control command of the suction motor;
a handle that accommodates the main PCB and that is configured to couple to the main body in a first direction; and
a connector located at the main body,
wherein the main PCB is configured to connect to the connector in the first direction based on the handle coupling to the main body in the first direction,
wherein the main PCB comprises a plurality of pads and a slit,
wherein the connector comprises a plurality of connecting pins that are configured to contact the plurality of pads and a slit insertion protrusion that is configured to insert into the slit,
wherein the connector is attached to an outer surface of the main body and protrudes outward of the outer surface of the main body, and
wherein the main PCB is configured to couple to the connector based on the handle moving along the outer surface of the main body in the first direction.

2. The cleaner of claim 1 , wherein the slit is disposed between two pads adjacent to each other of the plurality of pads.

3. The cleaner of claim 2 , wherein the plurality of pads comprise:
first and second pads disposed on a first surface of the main PCB and spaced apart from each other; and
third and fourth pads disposed on a second surface, which is a surface opposite to the first surface of the main PCB, and spaced apart from each other, and
wherein the slit is disposed in a region between the first and second pads and a region between the third and fourth pads.

4. The cleaner of claim 3 , wherein the first and third pads face each other, and the second and fourth pads face each other.

5. The cleaner of claim 3 , wherein the plurality of connecting pins comprise:
first and second connecting pins provided on the first connecting body and spaced apart from each other; and
third and fourth connecting pins provided on the second connecting body and spaced apart from each other, and
wherein the slit insertion protrusion is disposed in a region between the first and second connecting pins and a region between the third and fourth connecting pins.

6. The cleaner of claim 5 , wherein the first and third connecting pins face each other, and the second and fourth connecting pins face each other.

7. The cleaner of claim 1 , wherein the connector comprises:
first and second connecting bodies spaced apart from each other;
a bridge body configured to connect the first connecting body to the second connecting body; and
a PCB receiving space defined between the first connecting body and the second connecting body, and
wherein the slit insertion protrusion is disposed in the PCB receiving space.

8. The cleaner of claim 7 , wherein the bridge body connects the first connecting body to a lower portion of the second connecting body, and
wherein the main PCB is accommodated in the PCB receiving space downward from an upper side of the PCB receiving space.

9. The cleaner of claim 7 , wherein the slit insertion protrusion protrudes from the bridge body to the PCB receiving space.

10. The cleaner of claim 7 , wherein the slit insertion protrusion protrudes from one of the first connecting body and the second connecting body to the other one.

11. The cleaner of claim 7 , wherein the slit insertion protrusion connects the first connecting body to the second connecting body.

12. The cleaner of claim 7 , wherein one portion of each of the plurality of connecting pins is disposed in each of the connecting bodies, and another portion protrudes from each of the connecting bodies to the PCB receiving space.

13. The cleaner of claim 7 , wherein each of the plurality of connecting pins is an elastically deformable conductor.

14. The cleaner of claim 1 , wherein the main PCB comprises a first PCB and a second PCB, and
wherein one of the first PCB or the second PCB is connected to the connector.

15. The cleaner of claim 1 , wherein the main PCB is installed to stand up on the handle.

16. The cleaner of claim 1 , wherein the handle is configured to couple to the main body based on the handle moving in the first direction relative to the main body.

17. The cleaner of claim 1 , wherein the plurality of connecting pins are configured to come into contact with the plurality of pads based on the handle moving along the outer surface of the main body in the first direction, and
wherein the slit insertion protrusion is configured to insert into the slit based on the handle moving along the outer surface of the main body in the first direction.

18. The cleaner of claim 1 , wherein the main body comprises a dust separator configured to separate dust from air using a cyclone flow, and
wherein the first direction is parallel to an axis of the cyclonic flow.

19. The cleaner of claim 18 , wherein the suction motor is located above the dust separator.
