Abstract

An audio jack includes an insulated base including an upper plate and a lower plate connected to the upper plate, wherein a connecting portion between the upper plate and the lower plate forms a socket for plugging an audio plug, and a slot, formed between facing surfaces of the upper plate and the lower plate, is configured for installing a circuit board in a plugging manner; and a metal contact terminal configured to electrically connect the audio plug plugged into the socket to a corresponding conductive trace on the circuit board installed in the slot.

First claim

What is claimed is:

1. An audio jack, comprising:
an insulated base including an upper plate and a lower plate connected to the upper plate, wherein a connecting portion between the upper plate and the lower plate forms a socket for plugging an audio plug, and a slot, formed between facing surfaces of the upper plate and the lower plate, is configured for installing a circuit board in a plugging manner, the slot including first and second parallel slots and a third slot connecting the first and second parallel slots; and
a metal contact terminal configured to electrically connect the audio plug plugged into the socket to a corresponding conductive trace on the circuit board installed in the slot.

2. The audio jack according to claim 1 , wherein the first and second parallel slots are formed between the facing surfaces of the upper plate and the lower plate; and
the facing surfaces of the upper plate and the lower plate are configured to hold the circuit board after the circuit board is installed.

3. The audio jack according to claim 2 , wherein a central axis line of the socket is parallel to the first and second parallel slots.

4. The audio jack according to claim 1 , wherein a first end of the metal contact terminal forms a contact point in the socket, and a second end of the metal contact terminal forms a contact point in the slot.

5. The audio jack according to claim 4 , wherein the contact point in the slot formed by the second end of the metal contact terminal is an elastic contact point.

6. The audio jack according to claim 1 , further comprising:
a plurality of metal contact terminals insulated from each other.

7. The audio jack according to claim 6 , wherein contact points formed by the plurality of metal contact terminals, respectively, in the slot are evenly arranged in a slot direction of the slot.

8. An electronic device, comprising:
a circuit board; and
an audio jack coupled to the circuit board,
wherein the audio jack includes:
an insulated base including an upper plate and a lower plate connected to the upper plate, wherein a connecting portion between the upper plate and the lower plate forms a socket for plugging an audio plug, and a slot, formed between facing surfaces of the upper plate and the lower plate, is configured for installing the circuit board iii a plugging manner, the slot including first and second parallel slots and a third slot connecting the first and second parallel slots; and
a metal contact terminal configured to electrically connect the audio plug plugged into the socket to a corresponding conductive trace on the circuit board installed in the slot.

9. The electronic device according to claim 8 , wherein the first and second parallel slots are formed between the facing surfaces of the upper plate and the lower plate; and
the facing surfaces of the upper plate and the lower plate are configured to hold the circuit board after the circuit board is installed.

10. The electronic device according to claim 9 , wherein a central axis line of the socket is parallel to the first and second parallel slots.

11. The electronic device according to claim 8 , wherein a first end of the metal contact terminal forms a contact point in the socket, and a second end of the metal contact terminal forms a contact point in the slot.

12. The electronic device according to claim 11 , wherein the contact point in the slot formed by the second end of the metal contact terminal is an elastic contact point.

13. The electronic device according to claim 8 , wherein the audio jack further includes:
a plurality of metal contact terminals insulated from each other.

14. The electronic device according to claim 13 , wherein contact points formed by the plurality of metal contact terminals, respectively, in the slot are evenly arranged in a slot direction of the slot.
