Modular plugs and sockets

technical field

The invention relates to a plug and socket structure.

Background technique

The terminal or connector structure (terminal/connector) used in today's electronics industry is mostly the basic structure design of various types of male/female body (male/female), and its main purpose is to serve as electrical connection or signal transmission. At present, there are many types of terminal components or connectors used in the industry and consumer electronics. Take the transmission of video signals as an example. According to different video format specifications, the terminal specifications at least include AV terminals (audio/video, audio/video terminals) , S terminal (separate, independent video terminal), component terminal (Component Y/Cr/Cb signal), DVI interface (Digital Visual Interface, digital video interface), and the most popular HDMI interface (High Definition Multimedia Interface, high-definition Multimedia interface); and in the application of printed circuit board (PCB board), various types of connector specifications are too numerous to enumerate, such as electronic components, cable guides and peripheral external hardware devices, all adopt plug-in configuration structure . Take hard disk connection as an example, as shown in FIG. 1 , which is a schematic diagram of a conventional cable connector. Traditional hard disk devices are mostly connected to the computer motherboard with a buswire structure 100. Generally, the buswire structure 100 has its cable plug 102 set on the movable end, which is the two ends of the cable in this example, and the pin header The box 104 is disposed on the fixed end, in this example, on the hard disk end and the motherboard respectively. Use the corresponding plug group of the cable plug and the pin header box, so that the data signal between the two can be conducted and transmitted. As shown in Figure 1, there are two rows of pins (pins) 106 in the pin header box. The pin headers 106 are welded and fixed on the circuit board 107 underneath, and each pin header will correspond to a slot on the cable plug. Each slot corresponds to the wire body 108 to achieve electrical connection when inserted.

The pin header and row seat connection method of the male and female terminal structure has been widely used in the electronics industry, especially in the connection of peripheral devices and devices on the motherboard, such as power lines, data transmission lines, central processing unit sockets (CPU sockets) ), or memory slots, etc. Due to the ever-changing functions of electronic products and the constant evolution of their specifications, a variety of male and female seat structures have been derived. Each seat has its own pin count, pin length, and pin count. Pitch, number of slots, etc. For example, as far as the power transmission source line is concerned, the main power base of the general ATX specification (Advanced Technology Extended) is designed with 24 pins, and the power base of ATX 12 volts is 4-pin pins; for floppy disk hard disk transmission, the floppy disk (Floppy) has 34 pins, and the ATA/IDE (Advanced Technology Attachment/Integrated Device Electronics) specification has 40 pins. The UDMA standard (Ultra DirectMemory Access) cable base has 80 pins. In addition to the change in the number of pins, the layout of the various sockets will also be different. For example, the ATX 12-volt power supply socket above has a two-by-two 4-pin configuration, but the same is 4 pins. However, the power cord of the hard disk drive or CD-ROM is set in a single row of 4-pin pins. It is foreseeable that with the evolution of electronic products in the future, more pin header body specifications will inevitably be proposed.

Contents of the invention

In view of the above, in order to adapt to the changes and new regulations of the cable base body in the future, and to increase the remodelability of the male and female terminal base bodies, the present invention proposes a plug and socket structure that can be assembled. This structure is to combine more than one plug or socket side by side to form male and female seats of various shapes and pin numbers, which is suitable for making connectors of various specifications and interfaces.

The seat structure of the present invention is to connect the plug unit or the socket unit together to form a row of plugs or row seats through the mutual fitting of the convex part and the groove. After assembly, each plug is flush with each slot and has the same height. spacing. Through this connection method, the plug and the socket of the present invention can form male and female sockets with different shapes and numbers of pins, which can be mated correspondingly.

The purpose of the present invention is to provide a plug and socket structure that can be assembled with each other to form any pin number and pin layout; the advantages and spirit of the present invention can be further understood through the following specific implementation methods and drawings.
