Abstract

Disclosed is a micro universal serial bus (USB) connector. The micro USB connector according to the present disclosure may include a receptacle contact including a plurality of pins, a receptacle insulator coupled to one surface of the receptacle contact, a support plate disposed on an opposite side to the receptacle contact across the receptacle insulator, and being clear of a part opposite to a pin as a power terminal of the receptacle contact, and a receptacle shell covering an exterior of the receptacle insulator where the receptacle contact and the support plate are supported.

First claim

What is claimed is:

1. A micro universal serial bus (USB) connector, comprising:
a receptacle insulator;
a receptacle contact including a plurality of pins and coupled to one surface of the receptacle insulator;
a support plate coupled to another surface of the receptacle insulator and being opposite to the receptacle contact across the receptacle insulator; and
a receptacle shell covering an exterior of the receptacle insulator where the receptacle contact and the support plate are supported,
wherein a part of the support plate opposite to a pin as a power terminal of the receptacle contact is removed.

2. The micro USB connector according to claim 1 , wherein the support plate comprises:
a first support plate part disposed on an opposite side to the receptacle contact, and being clear of a part opposite to the pin as a power terminal of the receptacle contact; and
a second support plate part extending in an insertion direction of a plug connector from the first support plate part and having an increase in width.

3. The micro USB connector according to claim 2 , wherein a corner part formed between the first support plate part and the second support plate part has a round shape.

4. The micro USB connector according to claim 2 , wherein a corner part formed between the first support plate part and the second support plate part has a perpendicular shape.

5. The micro USB connector according to claim 2 , wherein a corner part formed between the first support plate part and the second support plate part has an obliquely slanted shape.

6. The micro USB connector according to claim 1 , wherein the pin as a power terminal of the receptacle contact has a shorter length than the other pin.

7. The micro USB connector according to claim 6 , wherein an effective contact length of the pin as a power terminal of the receptacle contact is longer than an effective contact length of a pin serving to transmit data.

8. The micro USB connector according to claim 1 , wherein a non-through hole-type pitch guide is present between a pin serving as a power terminal and a neighbor pin serving to transmit data among the plurality of pins of the receptacle contact.

9. The micro USB connector according to claim 1 , wherein the support plate is made of stainless steel.

10. An electronic device, comprising:
at least one processor;
a memory;
at least one program stored in the memory and configured to be executed by the at least one processor; and
a micro universal serial bus (USB) connector,
wherein the micro USB connector is a micro USB connector according to any one of claims 1 through 9 .

11. An electronic device, comprising:
a battery mounting section;
a charger circuit configured to receive power from a micro universal serial bus (USB) connector and charge a battery mounted in the battery mounting section;
a charge controller configured to perform control to charge the battery mounted in the battery mounting section; and
a micro USB connector connected to an external charger terminal through a micro USB cable to supply power to the battery mounted in the battery mounting section,
wherein the micro USB connector is a micro USB connector according to any one of claims 1 through 9 .

12. The micro USB connector according to claim 1 , wherein the removed part of the support plate exposes an entirety of the pin as a power terminal.

13. The micro USB connector according to claim 1 , wherein the removed part of the support plate exposes an entirety of the pin as a power terminal and a part of a pin adjacent to the pin as a power terminal.

14. The micro USB connector according to claim 1 , wherein the removed part of the support plate exposes an entirety of both the pin as a power terminal and a pin adjacent to the pin as a power terminal.
