Abstract

This paper relates to a computer signal cable that connects a computer monitor and a computer main body. In the related art, three lead wire connection terminals for grounding inserted into a D-sub connector are conventionally grounded. Only one lead wire connection terminal for earth) is used, and instead, three hole pins of the D-sub connector into which the lead wire connection terminal is inserted are grounded in common. Thus, the grounding lead connection terminal D is inserted. If multiple hole pins of the -sub connector are grounded in common, the entire manufacturing process is much simpler than the conventional one because only one lead wire connection terminal is inserted and welded.

Description

Computer signal cable

This paper is about the computer signal cable connecting the computer monitor and the computer body. The same effect can be achieved by inserting and welding only one ground lead wire (Ground pin) inserted and welded to the D-sub connector. The D-sub connector is improved.

The computer signal cable is a connection cable that connects the VGA card of the computer to the monitor and outputs various signals (including color signals) from the computer to the computer monitor. Three coaxial cables (Red, Green, Blue color signal cables) and leadwires 3- D-sub connector is fastened to both ends of four composite coaxial cables.

As a method of fastening the D-sub connector 21 to both ends of the cable, peel off the sheath of the composite coaxial cable and each cable, and then branch and make 9-10 stranded wires (helix). After crimping the dog, it is inserted into the pinhole (pin) of the D-sub connector terminal to complete the signal cable for the computer. The lead wire is not a single line but is composed of several thin wires united together to form a single wire. Usually, seven thin wires 2 constitute a single twisted wire together. The same goes for the lead wires that follow.

The D-sub connector terminal that is fastened to both ends of the cable is usually called the A connector terminal that is fastened to the computer. It has 15 pinholes (pins), and 9 or 12 when using a coaxial cable with 10 strands. , Pinhole of No. 15 has a terminal with no terminal (pin) inserted. In addition, in the case of using a composite coaxial cable composed of 9 strands, the pinholes of Nos. 5, 9, 12, and 15 have a terminal without inserting a terminal.

Meanwhile, the D-sub connector terminal connected to the monitor side is called a B connector terminal, and a D-sub connector terminal having a 15-pin hole can be used in the same way as the A connector terminal, and nine connection pins are provided according to the type of computer monitor. D-sub connector terminals with (holes) or 10 connecting pins (holes) can be attached.

For reference, the functions of the pins inserted into each of the D-sub connector terminals (A connector terminals) having 15 pinholes and the color of the cable connected thereto will be described below.

The D-sub connector terminals shown in Table 1 above may change the positions of pins inserted into each pinhole according to the manufacturer of the computer and the monitor, and the color of the cable may be changed. As shown in Table 1, the conventional cable inserted into the connector terminal uses a composite coaxial cable composed of three coaxial cables (RGB cable) 25 and four lead wires 26, as shown in FIG. The ground lead wire of the wire should be stripped of the coating of each conductor end as shown in Fig. 2, and then crimped with each connection terminal 31, 31 ', 31 ", and then the D-sub connector terminal. The pins inserted in pinhole numbers 4, 10, and 11 of (21) are pins (terminals) for grounding connected in common to each other, while pinhole numbers 9, 12, and 15 are Pin is not inserted satin (see Fig. 5).

As such, the lead wires 26 connected to the pinholes Nos. 4, 10, and 11 of the conventional D-sub connector terminal have two conductive wires 32 connected to one connection terminal as shown in FIGS. 2 and 3. ) (33) overlapped and then crimped and connected, so the thickness of the crimped part (spiral part and sheathed part) becomes thicker, making it difficult to insert into the narrow pinhole of the D-sub connector terminal 21. There was a fear of disconnection and short circuit with other connection terminals around it.

Particularly, the first connection terminal 31 among the three connection terminals 31, 31 'and 31 "must be inserted into pin 10 of the D-sub contactor terminal to obtain a clear resolution on the monitor. The remaining two terminals 31 ′ and 31 ″ must also be correctly inserted into pinholes 4 and 11, respectively, making assembly difficult and time consuming for welding.

In particular, since each pinhole diameter is only about 0.7 mm, it is not only time-consuming but also very difficult to insert multiple terminals into each of these small holes and weld them.

Conventionally, after grounding three lead wires (Ground pins) to each other in common, the three terminals are inserted into the hole pins 4, 10, and 11 of the D-sub connector, respectively. Is composed of one connection terminal, and the 4th, 10th, and 11th hole pins of the D-sub connector are common to each other, and then only the other 10 hole pins of the holes are inserted. Hole pins may be left as hole pins.

That is, in the related art, since the lead wires are commonly grounded, three connection terminals are configured. However, in this paper, only one connection terminal is configured, and the 4, 10, and 11 hole pins of the D-sub connector are commonly grounded. The same effect can be obtained by inserting only two terminals.

In this proposal, in a general computer signal cable configured by inserting a plurality of lead wire terminals into a D-sub connector 21, three earth hole pins inserted into the back surface of the D-sub connector 21 by three The connecting piece 1 is integrally connected by the connecting piece 1 having the insertion recess 1 ", and the connecting piece 1 is made of copper material, silver material and brass material with low electrical resistance.

In addition, in forming the connecting piece 1, it is also possible to implement the wire 10 having elasticity having a plurality of (3) insertion grooves 10 'instead of forming a piece.

The D-sub connector has a structure in which a plurality of connection pins protrude from the front surface and a plurality of hole pins 22 into which a plurality of lead wire terminals are inserted into the rear surface thereof. The terminal corresponding to the earth line of (22) is connected to one connection piece (1) or wire rod (10) to connect three earth terminals integrally.

Therefore, when three hole pins of the D-sub connector are commonly grounded, the effect is the same as that of three conventional lead wire connection terminals in common, and the lead wire terminals inserted therein are You don't have to configure three, just one.

The present invention will be described in more detail with reference to the following examples.

Example 1 When the hole pin is anchored with the connecting piece 1 (see Fig. 7)

In the original D-sub connector terminal, the position of the pin inserted into each pinhole can be changed according to the manufacturer of the computer and the monitor, and the color of the cable can be changed. Therefore, the ground (earth) leadwire terminal inserted into the hole pin of the D-sub connector terminal does not necessarily need to be inserted only into the hole pins 4, 10, and 11, and can be inserted into other hole pins.

In this case, however, the pinhole of another D-sub connector terminal attached to the other side of the cable may be changed to match this. Therefore, the present invention does not constitute hole pins into which the ground lead wire terminals are inserted as hole pins 4, 10, and 11, but consists of hole pins 5, 10, and 15, and then connects the hole pins to the connecting pieces ( After common grounding in 1), ground lead wire terminal 11 is inserted only in hole pin 10 (see Fig. 7).

In this way, if the grounding of the three hole pins 5, 10, and 15, the same effect as the three grounding lead wires can be obtained. Therefore, the grounding lead wire terminal 11 is composed of one (seven thin wires). ) Can be configured only.

In the figure, 21 is a D-sub connector, 22 is a hole pin 23 is an inserted pin.

On the other hand, the connection piece 1 used in this paper in order to common ground 5 hole pin, 10 hole pin, 15 hole pin can be used, such as silver, aluminum, brass with good conductivity. In addition, when the plated connecting piece is plated with rust, it can be used for a long time without rusting, and by using the hole 1 'formed on one side, it is possible to easily ground three hole pins 5, 10 and 15 times. If you insert the hole 1 'with a pin and push it into the hole pin, the ground is easily made. When inserted by the insertion recess 1 "formed on the ground surface, the ground around the three hole pins is elastically wrapped. It will not fall.

Example 2 When the hole pin is to be anchored with a thin wire (10) (see Fig. 10)

In Example 1, the hole pins of the D-sub connector into which the earth lead wire terminals are inserted are not changed into hole pins 4, 10, and 11, but are changed to hole pins 5, 10, and 15, and then the connecting pieces (1). In Example 2, the ground pins of the D-sub connector into which the earth lead wire terminals are inserted are not changed. To form a thin wire 10 as shown in Figure 9 to the earth to the hole pin (4, 10, 11) integrally. (See Fig. 10)

In the above, the slender wire 10 having a plurality of insertion grooves 10 '(about 3 in the present state) has a thickness of about 0.3-0.4 mm, and if it is an elastic material having good conductivity, brass, silver, aluminum, etc. Any metal can be used.

In this way, if the ground wire (10, 4, 10, 11) of the D-sub connector is grounded with a thin wire (10) with good conductivity, the existing D without the need to change the hole pin position of the D-sub connector. -sub connector can be used as it is, it can be applied to conventional products as it is.

In addition, when the earth hole pin for the D-sub connector is ground with a thin wire 10, the same effect as that of three conventional lead wire connection terminals in common as in Example 1 is obtained. Only one lead wire terminal needs to be configured.

Conventionally, there should be three lead wire terminals for the ground pin, and it is thought that a clean image can be obtained only when the ground is common. Therefore, we have also developed a common grounding method for ground pin lead wires (Preliminary Registration No. 111861) that can make common grounding of the ground lead wires effective and obtain much easier and cleaner images than before. It was.

In the end, however, since the connection terminals consisted of three terminals, it was time-consuming and difficult to insert and connect three connection terminals to the D-sub connector. Moreover, the pinhole diameter was only about 0.7mm, which made the task even more difficult.

However, if the ground pin of the D-sub connector where the ground lead wire terminal is inserted as in this paper is grounded in common, the same effect can be obtained even if only one connection terminal is inserted. . That is, in the past, since three lead wires had to be configured, the manufacturing cost was expensive, the manufacturing process was complicated, and the thick three connection terminals had to be inserted into the small pinholes of the D-sub connectors and welded together. This work took a long time, and the work was very difficult, but this paper solved this problem. Only one lead wire connection terminal for the ground pin was manufactured (previously three), and only one of them was inserted into the connector. Since all the inserted pins are integrally connected, the same effect as that of inserting three conventional inserts can be obtained, and since only one inserted is welded, the welding is easy and the effect is very excellent in the overall process.
