The present invention relates to a peripheral device of a computer, and more particularly to an extension slot.

As shown in FIG. 1, the computer basically includes a computer main unit (CPU) for performing all operations and an expansion device thereof, and a keyboard for transmitting user commands to the PC (hereinafter, referred to as PC). It is composed of input devices such as KB) and mouse (MS), and output devices such as monitor (MT) and printer (PR) that the PC delivers the results of the processing board to the user.

For the PC, these peripheral devices are connected through a port to communicate with the PC, which is divided into serial and parallel ports according to the port data transmission method. The printer (PR) is connected to the serial port is connected to the parallel port.

Here, the name of the port is systemic, and the slots S; S1 to S3, which are physically configured with various connectors, may refer not only to the port but also to the connector. Hereinafter, the slots S; S1 to S3 are used interchangeably in the meaning of ports or connectors.

Such a port is installed as slots S; S1 to S4 in a mother board (MB) in which a CPU is installed as shown in FIG. 2, and a daughter is provided in these slots (S; S1 to S3). (daughter) Boards of board-type peripheral devices, commonly known as a card (CD; CD), are inserted into the connection board.

On the other hand, peripheral devices to be connected to the outside of the casing (K) of the PC, such as the printer (PR) or the mouse (MS), have a pin or jack connector (TJ) installed on the outside of the card (CD) and the printer The jack or pin connector (TP) at the tip of the cable (CB) connected to the (PR) or the mouse (MS) is connected to this pin or the jack connector (TJ). At this time, the pin or jack connector (TJ) on the PC side is sometimes referred to as a port or slot, and the pin and jack connectors (TP, TJ) have a pin-jack configuration that engages with each other. -piece) generally termed the connector T2.

Meanwhile, slots S; S1 to S4 to which the card CD is coupled are generally composed of edge connectors EC shown in FIG. 3, which will be described later.

On the other hand, slots S; S1 to S4 provided in the mother board MB basically have three or four spare slots S4 for connection to a sound card or a modem, as well as an input / output device. Depending on the multimedia and networking, a sound card or modem is required, and most CD-ROM drives are provided, so that only one free slot S4 can be used by the user.

However, a general PC such as a 1BM compatible model is provided with an 80-series CPU and can be used as it is for designing, simulating, or experimenting with a control circuit using an 80-series microprocessor.

Such a test circuit TC is generally formed by inserting an IC light component PT on a bread board (BB of FIGS. 1 and 2) and connected to a power supply by jumper wires (JW). It is connected to the controller and the PC.

However, as described above, there is only one free slot (S4) in the PC, and in order to connect the jungfer wire (JW) to the free slot (S4), the casing (K) of the PC is removed and work is performed in a tight space. In general, a slot expansion system as shown in FIG. 2 is used.

Such a slot expansion system plugs a control card CC into a daughter board type into a spare slot S4 of the main board MB, and controls an extension bay XB having a plurality of slots S '. The card CC is connected through a cable CB 'connected to the two-piece connector T2'.

However, since the expansion bay (XB) is originally intended to connect the peripheral devices to complement the lack of free slots (S4) of the PC, the slot (S ') and the slots (S; S1 ~ S4) of the motherboard (MB) Similarly, it is comprised by the edge connector EC in which the card | CD CD 'is inserted.

That is, the edge connector EC is arranged in two rows of elastic contacts 101a and 10lb formed of leaf springs on both sides of the body 100 made of an insulating material, as shown in FIG. 1 to 1 correspond to the connection patterns 102a and 102b formed by patterning copper foils on both surfaces of the CD.

Accordingly, it is very difficult to connect the jumper wires JW to each of the elastic contacts 51a and 51b of the edge connector EC to maintain proper connection. When soldering for connection, the edge connector EC There is a problem that reuse is difficult.

At this time, when the test circuit TC is mounted on the circuit board PCB having the connection patterns 61a and 61b instead of the bread board BB, the test circuit TC is inserted into the slot S 'of the edge connector EC. Although connection is possible, it is practically impossible to configure the mounting circuit individually for the design or experiment of the circuit.

In addition, even if the card (CD) or circuit board connected to the edge connector (EC) is formed by connecting a cable having another connector to which a jumper wire (JW) can be connected, the connector has a large number of connection points. It is also very difficult to find the connection point and connect the jumper wire JW to maintain the connection.

Accordingly, an object of the present invention is to provide an expansion slot that can be easily connected to any connection means such as a jumper wire to communicate with a PC.

In order to achieve the above object, an expansion slot according to the present invention includes a substrate having one end of a connection pattern connected to a spare slot of a PC or a slot connected thereto, and one or a plurality of connection slots installed on the substrate and correspondingly connected to a connection turn turn.
