Abstract: A thin type battery is provided, including a shell body, a soft packaging cell, and an electric connector. The soft packaging cell is disposed in the shell body and includes a battery body and a top sealing area. The electric connector is connected electrically to the soft packaging cell. The electric connector can be plugged by a joint connector in a first direction or a second direction, so that by disposing the joint connector on a mobile electronic device, the thin type battery can be plugged into the mobile electronic device through the electric connector in the first direction or the second direction, supplying power.

Abstract: A combination of a thin type battery and a circuit board is provided, including a thin type battery, a circuit board, and a joint connector. The thin type battery includes a shell body, a soft packaging cell, and an electric connector. The joint connector is disposed at the circuit board and connected electrically to a circuit of the circuit board. The soft packaging cell of the thin type battery is disposed in the shell body and includes a battery body and a top sealing area. The electric connector is connected electrically to the soft packaging cell. The electric connector can be plugged into the joint connector in a first direction or a second direction, so that the thin type battery can be plugged into the mobile electronic device through the electric connector in the first direction or second direction, to supply power.

Abstract: An electric connector is provided, including a first insulating body and a plurality of conductive terminals. The first insulating body includes two positioning grooves and a plurality of terminal grooves. Each positioning groove has a first socket and a second socket. A concave portion, a first guiding groove, and a second guiding groove are disposed at a groove wall of each positioning groove. The first guiding groove extends from the first socket in a first direction to the concave portion. The second guiding groove extends from the second socket in a second direction to the concave portion. The terminal grooves are disposed at an interval between the two positioning grooves. Each terminal groove has a third socket and a fourth socket. The conductive terminals are disposed individually in the terminal grooves. A joint connector is capable of being plugged into the electric connector in the first or second direction.

Abstract: An encapsulation structure of a thin type battery for encapsulating a battery is provided. The battery includes a battery body and a top sealing area having a thickness smaller than that of the battery body. The encapsulation structure of a thin type battery includes a frame body and an extending wall. The frame body includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall. Two ends of the third sidewall are connected to the first sidewall and the second sidewall, respectively. The fourth sidewall is opposite the third sidewall. Two ends of the fourth sidewall are connected to the first sidewall and the second sidewall, respectively. The extending wall is connected to one side of the first sidewall and clamped at the third sidewall and the fourth sidewall. In addition, a thin type battery is also provided.
