Detachable socket electrical connector

The present invention relates to a detachable socket electrical connector, and more particularly to a socket electrical connector that utilizes a detachable combination of a pedestal and a socket electrical connector to reduce the difficulty of soldering the pedestal to the circuit substrate.

The technology continues to advance, and various novel products are successively introduced. The general products are connected to other devices by wired transmission, and connected by various connectors to bridge the signals and connect with the male connectors. The device is connected to the female connector.

Take the Universal Serial Bus (USB) connection interface commonly used today as an example to transmit power and signals, and it is easy to carry and easy to use and plug-and-play. A connection hole of various portable electronic devices such as a mobile communication device and a digital camera, and a corresponding transmission line.

With the electronic device being light and thin, the electrical connector on the electronic device must also reduce the volume occupied. In particular, it is necessary to install a plurality of electrical connectors conforming to different electronic signal transmission specifications for When different plug connectors are plugged in, since each electrical connector needs to occupy a certain volume and needs to space the space of each electrical connector, the space is a waste of space; An all-in-one electrical connector that integrates different electronic signal transmission specifications.

However, the all-in-one electrical connector also has multiple sets of connection terminals, which also enables multiple groups of connections. How to connect the terminal end of the terminal to the predetermined circuit substrate is also a problem to be solved. For example, if the end legs of the plurality of sets of connection terminals are electrically connected to the predetermined circuit substrate by the through-hole soldering method, the multi-layer circuit setting cannot be performed on the perforated position of the circuit substrate, resulting in wasted limited circuit design space. Moreover, for example, when the end legs of the plurality of sets of connection terminals are electrically connected to the predetermined circuit substrate by surface soldering, when the end pins located at the bottom position of the electrical connector are shielded by the electrical connectors, the surface soldering is caused. The difficulty is relatively increased.

In order to solve the problems caused by the prior art, the present invention proposes a detachable socket electrical connector comprising a base and at least one socket electrical connector. The pedestal is disposed on a predetermined circuit substrate, the pedestal is provided with at least one jack and a plurality of first terminals, and the first contact end of the first terminal is located in the jack, and the first soldering end of the first terminal Soldering on the circuit substrate; the socket electrical connector is respectively provided with a first tongue plate and a second tongue plate extending in different directions, and a plurality of third terminals and a third terminal are disposed on the first tongue plate and the second tongue plate One end is provided with a first external connection end on the first tongue plate, and one end of the third terminal is provided at a first internal connection end of the second tongue plate. By separating the base and the socket electrical connector, the base can be set to a small volume, so that the first soldering end of the first terminal provided by the base is not easily shielded, thereby reducing the difficulty of soldering with the circuit substrate; The socket electrical connector is coupled to the socket of the base through the second tongue plate such that the third terminal of the socket electrical connector is electrically connected to the first terminal of the socket, and the socket electrical connector is further transmitted through the first tongue and the outer portion The preset electrical connectors are engaged.

The present invention further provides a detachable socket electrical connector, wherein the receptacle electrical connector can be directly coupled to a predetermined connector receptacle, the receptacle receptacle being formed by a housing of an electronic device. The pedestal can be first placed inside the casing of the electronic device, and the socket of the pedestal Corresponding to the connection port of the electronic device; afterwards, the socket electrical connector is inserted from the outside of the electronic device toward the inside of the connection socket, so that the second tongue of the socket electrical connector is combined with the socket of the base and through the socket The waterproof ring provided by the electrical connector forms a sealed waterproof function between the electrical connector of the socket and the housing of the electronic device.

The present invention further proposes a detachable socket electrical connector, wherein the socket electrical connector can incorporate a housing that is coupled to the receptacle electrical connector and located opposite the first tongue.
