2. The Related Art
With the development of variety of electronic peripheral devices, the transmission interface is achieved by various means. Therefore, various electrical connectors having different structures and functions are employed widely as transmission interfaces for satisfying various needs of different hardware devices. In general, electrical connectors are mounted individually on the edge of a printed circuit board (PCB) in an electronic device, and arranged in juxtaposed or parallel manner. However, the arrangement of the electrical connectors occupies too much inner space of the electronic device, and brings some hindrance to the miniaturization of the electronic device. Moreover, it is time-consuming and complicated to individually mount more than one electrical connector on the PCB of the electronic device. The existing defects as described above have also been shown in the following specific example.
Generally, a common consuming electronic device is equipped with three types of electrical connectors in which a power jack is provided as a power signal transmission interface, an audio jack is provided as an audio signal transmission interface and a radio frequency jack is provided as a RF signal transmission interface. When the electrical connectors as mentioned above are assembled with a motherboard of the electronic device individually, it should be considered whether the capacity of the electronic device is enough for holding the electrical connectors, together with consideration of fitness between the shapes of the electronic device and the electrical connectors. So, it brings much inconveniences and restrictions to assembly manipulation.

The upper and lower covers 11, 12 are assembled to be the insulation cover 1 by means of ultrasonic soldering. A cutout 15 is defined on the bottom surface of the lower cover 12. The insulation cover 1 further has three cavities 13, 14 formed on one lateral side thereof, in which two cavities 13 are circular and defined respectively as the first cavity and the third cavity, another cavity 14 is square and defined as the second cavity (as shown in FIG. 3). Each of the two circular cavities 13 consists of a pair of semicircular notches 131, 132 disposed respectively on the upper cover 11 and the lower cover 12 and in symmetric configuration. The square cavity 14 consists of a pair of rectangular notches 141, 142 disposed respectively on the upper cover 11 and the lower cover 12 and in symmetric configuration. According to the preferred embodiment, the semicircular notches 131, 132 and the rectangular notches 141, 142 on the same of the upper and lower cover 11, 12 are arranged in a row. According to the preferred embodiment, the three cavities 13, 14 are provided respectively to receive three electrical connectors 3, 4, 5 with different functions, and the detail will be described below.
According to the present invention, the compound electrical connector 10 further comprises a plug connector 2, an audio jack 3, a power jack 4 and a radio frequency jack 5, together with a printed circuit board (PCB) 6 assembled in the insulation cover 1. The plug connector 2 includes a first contacting portion 21 passing through the cutout 15 and extending out from the bottom surface of the insulation cover 1, and a first soldering portion 22 connected with the first contacting portion 21 and soldered on the PCB 6. The audio jack 3 includes a second contacting portion 31 positioned in the first cavity 13 and a second soldering portion 32 connected with the second contacting portion 31.
