BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case where a printing cable used for electronic equipment is connected to a connector or the like for use.

[0002]

2. Description of the Related Art When a printing cable is attached to a connector of an electronic device, for example, according to the pin arrangement of the connector, if there are two types of signal lines on the same surface of the printing cable, the two types There are times when it is inevitable that the printed cable will be constructed so that signal line crossings occur (impossible answers occur). In such a case, conventionally, as shown in FIG.
A double-sided printing cable, in which different types of signal lines are printed on different surfaces, was used to attach the printing cable to the pins of the connector.

FIG. 5 is a diagram showing a double-sided printing cable. In FIG. 5, 1a and 1b are signal lines, 1a is printed on the back of the print cable, and 1b is printed on the front. 4a, 4
Reference numeral b is a connection hole to a connector corresponding to each of the signal lines 1a and 1b, and reference numeral 5 is a base (board) of the printing cable.

An example of connecting the double-sided printing cable in FIG. 5 to the connector will be described with reference to FIG. FIG. 6 is a cross-sectional view when the double-sided printing cable is connected to the connector 8 in the direction of arrow A. The printed surface 11 of the signal line 1a of the double-sided printing cable of FIG. 5 is directed to the connector body 8 side. Then, the connection hole 4a to the connector is connected to the pin 6a of the connector.

[0005]

Conventionally, the method of connecting the print cable to the connector by printing the signal lines of the print cable on both sides of the print cable according to the arrangement of the pins of the connector has been adopted. According to the method, since the signal lines are printed on both sides, the manufacturing cost of the printing cable itself is twice as high as that for single-sided printing. Further, when the print cable is connected not in the direction of arrow A but in the direction of arrow B, there is a problem that the positional relationship between the connection hole and the pin is opposite and the connection cannot be made.

The present invention has been made to solve the above problems, and an object thereof is to obtain a printing cable which does not require a manufacturing cost and which can be connected to a connector from any direction. There is.

[0007]

A printed cable according to the present invention is configured so that, for example, the printed cable is connected to a connector having two types of pins, a first type and a second type, in a direction in which a signal line of the printed cable extends. In this case, the first connecting portion for connecting to the first pin of the connector and the second connecting portion for connecting to the second pin and the signal line are provided on the same surface of the printing cable, The holes for passing the pins are provided in the direction in which the signal lines of the print cable extend corresponding to the connecting portions,
Further, one or more bent portions are provided between any one of the two connecting portions and the hole thereof.

[0008]

The printed cable according to the present invention is provided with the holes for passing the pins of the connector corresponding to the two kinds of connecting portions on the same surface, and further by providing the bent portion at one or more places, the connector is provided. It is possible to connect to a connector without being restricted by the pin arrangement of.

EXAMPLES Example 1. One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view showing a printed cable according to the present invention, and FIG. 2 is a sectional view in which the printed cable according to the present invention is connected to a connector. In FIG. 1, 1a and 1b are two types of signal lines extending in the direction C,
21, 22 and 23 are holes for passing pins of the connector, 31, 3
Reference numeral 2 is a bent portion, 31 is a valley fold, and 32 is a mountain fold. Reference numerals 4a and 4b are connection holes for connecting two types of signal lines to each of two types of pins of the connector. 5
Is the base of the printed cable.

An example of connecting the print cable of FIG. 1 to the connector according to this embodiment will be described with reference to FIG. Here, the connection hole 4a of the print cable is connected to the pin 6a of the connector.
Next, an example of connecting the connection hole 4b to the connector pin 6b in the direction of the arrow A will be given. First, the configuration of the print cable will be described. In the printed cable of FIG. 1, the holes 21, 22, 23 through which the pins of the connector are inserted, the bent portions 31, 32, and the connection hole 4 are designed in consideration of the distance between the pins 6a, 6b of the connectors to be connected. And That is, the distance L1 between the holes 21 and 22,
The distance L2 between the connection hole 4a and the hole 23 is equal to the distance L3 between the pins 6a and 6b (L1 = L2 = L).
3). Here, the intervals L4 and L5 may be any length that allows the print cable to be bent.

Next, a method of connecting the print cable will be described. Connect the printed surface 9 of the signal line of the cable to the connector body 8
Facing away from the connection hole 4b and the connector pin 6
Solder to b using the land 7b. next,
The bent portion 31 is valley-folded, the pins 6b and 6a of the connector are inserted into the holes 21 and 22, respectively, and the bent portion 32 is mountain-folded. Then, the connecting hole 4a is connected to the pin 6 of the connector.
through the land 7a and solder using the land 7a
Pass the pin 6b of the connector through.

Example 2. In Example 1, the bent portion is 2
Although it is provided in one place, as shown in FIG. 3, the number of bent portions may be any as long as it is one or more. In addition, the bending method of the cable is S-shaped as shown in FIG. 2 in the first embodiment, but the bending method is not the S-shaped shape but the U-shaped shape as shown in FIG. But it's okay.

Embodiment 3. In Example 1, the number of holes on the printed cable through which the pins of the connector pass is determined by the number of holes in the set of connections (4
There are three (21, 22, 23) for a, 4b), but this number may be any number. Further, the position of the hole may be anywhere as long as it is in the direction of the arrow C (FIG. 1) in which the signal line extends.

Example 4. In the first embodiment, an example in which the print cable is connected is limited to the arrangement of the pins of the connector, but as shown in FIG. 3, the print cable cannot be inserted from the direction of arrow D for some reason. The present invention is also effective in the case where the print cable cannot be connected to the connector and the insertion direction of the print cable is restricted.

Example 5. In the third embodiment described above, the example in which the print cable is connected while being restricted in the inserting direction of the print cable has been described. However, as shown in FIG. 4, the connector is installed in a narrow box and the cable is extended in the direction of the broken line. The present invention is effective even in the case where the installation location of the connector is limited, such as when it is not possible.

Example 6. In the first embodiment, an example of a print cable having a structure in which two types of signal lines intersect (impossible solution) occurs in the print cable.
The present invention is also effective for a printed cable in which no kind of signal line crossing occurs.

Embodiment 7. Although the example of using the single-sided printing cable is described in the first embodiment, when focusing on only one side of the double-sided printing cable, a pair of connecting portions and holes are arranged in the extending direction of the signal line. The present invention is also effective for a double-sided printing cable as long as it has a bent portion.
