Description

Manufacturing Technology of Multi-connector}

The present invention provides several types of units on a printed circuit board interconnecting electrical conductors to enable devices having different standard power and data input / output connection devices to be connected as external devices. A multi-connector having a connector attached thereto is provided. More particularly, the present invention relates to a technology for manufacturing a composite connection device having high reproducibility and productivity by mounting a plurality of unit connection devices on a single printed circuit board, which is easy to carry and use, and connects them with the conductors of the printed circuit board.

Various multimedia devices such as computers, MP3s, PMPs, digital cameras, mobile phones, etc. are appearing, but the standard of the built-in devices for power and data input / output of these devices differs depending on the company and the purpose, and additional devices corresponding to the number of devices All the accessories must be carried, and there is a problem in data input / output and compatibility between devices, and a complex connection device is required for easier data exchange and compatibility.

   However, most of the conversion connectors are 1: 1 conversion connectors manufactured by connecting unit connectors of different standards on both ends of the cable, and in the case of some composite connectors, each electrode terminal is connected by wires or metal pieces. And plastic extrusion or injection molding is used to meet the limitations of manufacturing technology as the size of the connecting device is diversified and the size is smaller.

In the prior art, for power supply, data input / output, and sharing of devices incorporating connection devices of different standards, there must be a device matching the unit connection device according to each built-in standard. Although the connecting devices corresponding to the connecting devices can be connected to each other by wires and connected to each other, a number of conversion connecting devices are required for compatibility due to the miniaturization and diversification of equipment. In other words, various portable devices have emerged, and the necessity for the connection and compatibility between them is increasing, but the size of the connection device is diversified and the size thereof is further miniaturized. There is a need for alternative technology.

The present invention relates to an additional composite connection device manufacturing technology capable of increasing compatibility between devices that are difficult to connect due to differences in power and input / output connection devices built in portable small information electronic devices. To this end, implement a circuit for connecting electrode terminals having the same function to a printed circuit board, and attach a large number of unit connection devices having jacks or plugs having power and input / output pins attached thereto using surface mount technology (SMT). The present invention relates to a multi-connector manufacturing technology capable of increasing connectivity, reliability, and compatibility.

According to the present invention, a unit connection device of a jack or a plug having a power line and a data input / output pin is formed on the printed circuit board to form conductors on the printed circuit board to connect electrode terminals having the same function but different functions to each other. Is a manufacturing technology for composite connecting devices mounted on or around a printed circuit board. In order to prevent physical and environmental damage of a composite connecting device composed of a printed circuit board and a plurality of unit connecting devices attached thereto, a technology for manufacturing a composite connecting device is provided by covering an upper and a lower case. Of course, instead of the upper and lower cases, a printed circuit board mounted with the components of the present invention may be molded by conventional plastic injection or extrusion technology to protect the substrate and related components.

Conventional conversion or complex connection devices use wires or metal pieces to connect multiple power and input / output terminals of different specifications, so the number of connection devices is limited, and in particular, as the connection devices become smaller, three-dimensional wire connection methods are used. It's getting harder to do. Therefore, when using a printed circuit board instead of wires as in the present invention, the connection lead circuits are easily connected and reproducible, and various small terminals can be precisely attached, thereby making it easy to manufacture a compact composite connection device. Therefore, a number of additional connection or connection devices are required depending on the type of device, and thus, the composite connection device of the present invention can be used as a portable device, economical, and compatibility between related devices.
