Receptacle connector for a battery in the mobile electric device
Provided is a receptacle connector for a battery in a mobile electric device. The receptacle connector includes a contact terminal, a connection terminal, and an extension portion. The contact terminal electrically contacts a plug connector of the mobile electric device. The connection terminal is fit and soldered in a through hole of a battery PCB, and is integrally formed with the contact terminal. The extension portion is bent and extends from a front end of the connection terminal to form a solder receiving space for receiving solder flowing through the through hole of the PCB together with the connection terminal while a soldering operation is performed on the connection terminal. The extension portion together with the connection terminal is fit and soldered in the through hole of the PCB.
1. A receptacle connector for a battery in a mobile electric device, soldered and coupled to a printed circuit board (PCB) of a battery attached to and detached from the mobile electric device, the receptacle connector comprising:
a contact terminal electrically contacting a plug connector of the mobile electric device;
a plurality of connection terminals, wherein each connection terminal being fitted and soldered in a through hole of the battery PCB, each connection terminal being integrally formed with the contact terminal; and an extension portion extended from a front end of each connection terminal, being fitted to be soldered in the through hole of the PCB,
wherein the extension portion is bent in a “U” shape to form a solder receiving space for receiving solder flowing through the through hole of the PCB in the soldering operation of the connection terminal, and further including a solder inflow hole for allowing the solder to flow into the solder receiving space, a seat bent at the end of the extension portion to be supported on the top surface of the PCB, and a hooking portion protruded from the outer surface thereof to be engaged on the bottom surface of the PCB.
