Description

Electrical connector

The present invention relates to an electrical connector, especially an electrical connector that can be connected to at least two different external terminal blocks of different specifications.

At present, the most popular signal transmission specifications for display devices such as televisions or computer screens on the market are the High Definition Multimedia Interface (HDMI) and Display Port interfaces, among which the HDMI interface has nineteen terminals. The Display port interface has twenty terminals. The width of the tongue plate of the above two interface sockets and the position and spacing of the nineteen terminal pins of the lower surface of the tongue and the board are the same, and only one terminal pin is provided in the Display port interface. In addition, the display port interface plug width is larger than the HDMI interface plug. In order to meet the needs of today's electronic products, some manufacturers have designed sockets that can be plugged into HDMI and Display port plugs at the same time.

Both the HDMI plug connector and the Display port plug connector must be plugged into the integrated receptacle electrical connector in a specific orientation. However, since the side length of the interface port connector to the interface is larger than the side length of the HDMI plug connector to the interface, in the conventional integrated socket electrical connector, the side length of the interface is connected by a Display port plug. The pair interface of the device is the reference. That is, for the user, the appearance of the interface of the integrated socket electrical connector can only judge the insertion direction of the Display port plug connector, but the insertion direction of the HDMI plug connector cannot be determined, and further, in the conventional Butt joint tongue in integrated socket electrical connector It adopts the same configuration as the tongue of the traditional HDMI socket connector, and has two right angles under the two oblique angles. Therefore, when the HDMI plug connector is inserted into the integrated socket electrical connector, the socket is electrically connected. The tongue inside the connector is easily damaged by impact.

In addition, at present, the insulating base of the electrical connector and the circuit board are all closed, which is inconvenient for inspection and maintenance of the process.

Inside, extending to the rear of the body and extending a second distance from the upper bend, bending backward and extending a distance, then bending a distance, and resting behind the body, the second wiring group is generally a plurality of Two consecutive L-shaped second-order bodies that are flush with each other, and the second distance is greater than the first distance, and the first wiring group is received and supported by the receiving slots of the insulating base body and the body The second wiring group is disposed on the upper surface of the tongue plate and extends toward the rear of the body, and the second wiring group is disposed on the lower surface of the tongue plate and extends toward the rear of the body. A wiring group is interleaved with the second wiring group and arranged in a coplanar manner behind the body. The electrical connector can be connected to a circuit board, and the insulating base body is further provided with a plurality of protruding posts, the protruding pillars are connected to the circuit board, so that the insulating base body forms at least one near the circuit board. Opening, through which the first wiring group and the second wiring group can be observed to facilitate inspection and maintenance of the process.

The electrical connector of the present invention can achieve the process of connecting the external terminal block multiple times, reducing the damage rate of the electrical connector, improving the convenience of process inspection and maintenance, as well as improving the strength and safety and prolonging the service life of the electrical connector. .

The reason is that this creation is to study the above problems. After a long period of design and development, the "electrical connector" of this case is completed to solve the problem that the conventional electrical connector fails to achieve.
