Abstract

PROBLEM TO BE SOLVED: To provide a connection method in which plural real wiring harnesses can be connected to a connection means provided with plural connection terminals of a narrow pitch, and in which wire breakage of the real wiring harnesses can be prevented at the time of removing connection. SOLUTION: To a real wiring connection terminal 11 in a connector socket 10 provided with plural connection terminals mounted in a narrow place in an electronic device at a narrow pitch, a real wiring connector pin 15 of a real wiring harness 13 is inserted to be connected. In the meanwhile, a dummy harness 14 and a connector pin 16 which are not used for real wiring are inserted to be connected to an empty connection terminal 12. In removing connection of the harness 13, 14 from the connector socket 10, as the whole body of the harness is pulled by hand around a binding part 17, pulling force is dispersed, so excessive force is not applied to the real wiring harness 13, thereby breakage of the real wiring harness 13 can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable connecting method for connecting a cable such as a parallel cable or a harness to a connecting means mounted on a circuit board mounted on an electronic device and an electronic device adopting this connecting method.

[0002]

2. Description of the Related Art As an electrical connection method in an electronic device, a cable such as a harness or a parallel cable formed by bundling a plurality of connection lines insulated from each other and a connection such as a connector socket mounted on a circuit board mounted in the electronic device It is known to connect using means.

For example, when connecting a plurality of harnesses for actual wiring to a connecting means having a plurality of connecting terminals such as a connector socket mounted on a circuit board of an electronic device,
As shown in FIG. 2, the connector pins 2 of the harness 1 for actual wiring are respectively inserted into the connection terminals 4 of the connector socket 3 to be connected, and the entire harness is bound by the binding portion 5 as necessary. Further, the other end of the harness 1 is provided with other connecting means such as a clip 8. In addition,
The other connection terminal 4a of the connector socket is an empty connection terminal to which the harness is not connected.

[0004]

When disconnecting the harness 1 from the connector socket 3, normally, the lead portion of the connector pin 2 is pressed with a fingertip and pulled out to remove, but the connection terminal 4 of the connector socket 3 is removed. As the pitch becomes narrower, it becomes difficult to pull out the connector pin 2 from the connection terminal 4 with a fingertip. Also,
Due to the structure of the electronic device, if the connector socket 3 is provided at a place where the fingertip cannot reach the connector socket 3, it becomes more difficult to pull out and remove.

Therefore, the entire harness connected to the connector socket 3 must be pulled by hand in the vicinity of the binding portion 5 to pull out the connector pin 2 from the connection terminal 4.
At this time, if the number of harnesses 1 to be used is small, an unreasonable pulling force is applied to the harnesses 1 and disconnection 7 may occur at the lead portions 6 of the connector pins 2.

The present invention provides a cable connecting method capable of preventing disconnection of the cable when the cable such as the harness 1 is pulled by hand and disconnected from the connecting means such as the connector socket 3, and an electronic device adopting the cable connecting method. There is a point to do.

[0007]

According to the present invention, when a plurality of cables are connected to a connecting means having a plurality of connecting terminals, a dummy cable is connected to an empty connecting terminal among the plurality of connecting terminals of the connecting means. Connecting.

Since the dummy cable is connected to the empty connection terminal, even if the actual wiring cable is pulled together with the dummy cable by hand, the pulling force is dispersed to the dummy cable. No force is applied.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A cable connecting method of the present invention will be described below with reference to FIG. In addition to the connection terminals 11 for actual wiring, a connecting means such as a connector socket 10 having an empty connection terminal 12 not used for actual wiring is mounted on a circuit board of an electronic device (not shown).

On the other hand, the actual wiring harness 1 is used as a harness.
In addition to 3, the dummy harness 14 that is not used for actual wiring is prepared, and the actual wiring harness 13 and the dummy harness 14 that is not used for actual wiring are bound by the binding portion 17 as necessary.

A connection method using the actual wiring harness 13, the dummy harness 14, and the connector socket 10 will be described below. Insert and connect the connector pin 15 of the actual wiring harness 13 to the actual wiring connection terminal 11 of the connector socket 10 mounted on a circuit board or the like of an electronic device (not shown), and connect the empty space of the connector socket 10. The connector pin 16 of the dummy harness 14 is inserted into the terminal 12 and connected. At this time, the other end 14a of the dummy harness 14 is preferably electrically insulated and floated.

As described above, when the dummy harness 14 is connected to the connector socket 10 together with the actual wiring harness 13, even if a pulling force is applied to the entire harness when the harness is removed from the connector socket 10, The pulling force is distributed to the dummy harness 14, the excessive pulling force is not applied to the actual wiring harness 13, and the disconnection of the actual wiring harness 13 can be prevented.

The connection method of the present invention is a particularly effective connection method when the number of actual wiring harnesses 13 connected to a connection means such as a connector socket is small.

[0014]

According to the present invention, in addition to the cable for actual wiring, the dummy cable is connected to the connecting means.
Even if the entire cable is pulled when the connection between the cable and the connecting means is disconnected, the cable can be prevented from being broken.
