Abstract

Provided are a guide-connected contactor and a portable electronic device comprising same. A guide-connected contactor, according to an embodiment of the present invention, comprises: an elastic conductor which comes in contact with a circuit board of an electronic device or a bracket connected to the circuit board; a functional element which is connected to the elastic conductor and has a first electrode and a second electrode on the upper surface and the lower surface, respectively; and a guide which is plate-shaped, has the functional element connected thereto, and is connected to a groove portion provided on a conductive case of the electronic device.

First claim

What is claimed is:

1. A guide-connected contactor comprising:
an elastic conductor configured to come into contact with a circuit board of an electronic device or a bracket coupled to the circuit board;
a functional element connected to the elastic conductor and having a first electrode and a second electrode on upper and lower surfaces thereof, respectively;
a guide having a plate shape, coupled with the functional element, and configured to be connected to a groove portion formed on a conductive case of the electronic device and
an alignment member formed on an upper surface of the guide to surround at least a portion of the functional element so as to align a position of the functional element, wherein the functional element is coupled to the guide through a solder,
wherein the guide is a medium for fixedly coupling the elastic conductor and the functional element, which are integrally formed, to the conductive case.

2. The guide-connected contactor of claim 1 , wherein the alignment member includes one of a photo imageable solder resist (PSR) ink, a heat resistant film, an overglass, and a nonconductive resin.

3. The guide-connected contactor of claim 1 , wherein the alignment member is provided on the upper surface of the guide except for a region on which the elastic conductor is laminated.

4. The guide-connected contactor of claim 1 , wherein the alignment member is integrally formed.

5. The guide-connected contactor of claim 1 , wherein the alignment member includes at least two alignment members symmetrically disposed.

6. The guide-connected contactor of claim 1 , wherein the alignment member is configured as a groove formed in the upper surface of the guide.

7. The guide-connected contactor of claim 1 , wherein the guide further includes a wing portion protruding from only a part of a side surface of the guide, and the wing portion has a shape corresponding to a shape of an opening portion extending outward from one side of an outer periphery of the groove portion.

8. The guide-connected contactor of claim 1 , wherein the guide has a through hole at a center thereof, the functional element is inserted into the through hole, a bonding member is fixedly provided between the functional element and at least a part of the through hole, and the guide includes a barrier portion provided on at least a portion around the through hole to prevent the bonding member from flowing downward.

9. The guide-connected contactor of claim 8 , wherein, when the functional element is inserted, the barrier portion is bent in an insertion direction of the functional element through the through hole.

10. The guide-connected contactor of claim 8 , wherein the barrier portion protrudes inward into the through hole, and a recess portion is formed in a lower surface of the functional element so that the functional element is mounted on the protruded barrier portion.

11. The guide-connected contactor of claim 8 , wherein the barrier portion includes a groove or a stepped portion provided on the upper surface of the guide.

12. The guide-connected contactor of claim 8 , wherein the functional element is fixed to at least a part of the through hole temporarily or permanently by the bonding member provided therebetween.

13. The guide-connected contactor of claim 1 , wherein the guide includes a conductor or a nonconductor, the conductor includes one of stainless steel (SUS), phosphor bronze, aluminum, and nickel silver, and the nonconductor includes one of a printed circuit board (PCB) material including FR4, a polyethylene terephthalate (PET) film, and a plastic.

14. The guide-connected contactor of claim 1 , wherein the guide is coupled to the groove portion by a conductive adhesive layer.

15. The guide-connected contactor of claim 1 , wherein the guide has a shape corresponding to a shape of the groove portion.

16. The guide-connected contactor of claim 1 , wherein the functional element further comprises:
a first test electrode provided on an upper surface of the functional element and electrically connected to the conductive case; and
a second test electrode spaced apart from the first test electrode by a predetermined distance.

17. The guide-connected contactor of claim 1 , wherein the functional element has at least one of an electric shock prevention function for blocking a leakage current of an external power source introduced from a ground of the circuit board of the electronic device, a communication signal transmission function for transmitting a communication signal introduced from the conductive case or the circuit board, and an electrostatic discharge (ESD) protection function for discharging static electricity introduced from the conductive case.

18. A portable electronic device comprising:
a guide-connected contactor according to claim 1 ; and
a conductive case having a groove portion to which the guide-connected contactor is coupled,
wherein the groove portion has a shape corresponding to a shape of the guide, and
the elastic conductor of the guide-connected contactor comes into contact with the circuit board or the conductive bracket provided at one side thereof with the circuit board.
