The present invention relates to a conversion gender, and more particularly, to a conversion gender for a mobile terminal that allows a charger, a hands-free, and a data cable to be used as they are even though the connectors of the mobile communication terminal are different.

In general, mobile terminals refer to portable electronic devices such as mobile phones, portable computers, palm PCs, PDAs, electronic organizers, digital cameras, camcorders, MP3 players, and PMPs. The trend is miniaturization.

In particular, such a mobile terminal is configured to configure various internal circuits according to manufacturers and models of mobile terminals, and is provided to enable interfacing by installing a plurality of connectors on one side of the mobile terminal housing as an interface for communicating with the outside. .

In particular, the IF connector for data communication or charging and the audio connector for inserting the earphone connector are mostly provided, so the charging is performed with the IF connector and the earphone function is separated to use the audio connector.

However, in recent years, as the mobile terminal, in particular, the cellular phone, has become thinner and lighter, it is not desirable to have a plurality of connectors in the cellular phone for design and application.

Therefore, the mobile phone is extended to the connector to perform charging and data communication at the same time to meet the slimmer of the mobile phone by providing a connector having a pin number of 20 pin (Pin) is configured.

Apart from the connector provided according to the manufacturer's request, a standard connector having 24 pins is adopted in most chargers and data communication cables, in order to prevent waste of resources and increase of economic burden by providing a charger. have.

Therefore, in order to match the number of connector pins according to the mobile phone model owned by the user, an additional connector conversion component called a gender changer is used.

Such genders are widely used as integrally having a male connector portion for matching different pin counts between interfaces.

However, such a conventional gender converts a 24 pin connector so that it can be matched with a 20 pin connector, but there is a problem that other pins, for example, a 24 pin connector cannot simultaneously match with a 20 pin connector and a 10 pin connector. .

In addition, in the conventional gender, for example, when an audio connector or a 10-pin connector is connected to a mobile phone using a 20-pin connector, an excessive electrical connection occurs to the mobile phone composed of 20-pin due to an unreasonable connection configuration to the input circuit part of the mobile phone. There is a problem that, there is a problem that the mobile phone malfunctions.

In addition, a problem arises in that some specific functions cannot be used due to an excessive electrical connection between connectors having different input structures. For example, if a 20-pin connector is normally connected, additional functions such as sending and receiving voice calls, making calls, and ending calls are performed.However, a conversion gender is used to convert 20 pins to 24 pins or 24 pins to 20 pins. In this case, only a voice call is transmitted and received, and additional functions such as call origination and call termination are not performed.
