Abstract

PURPOSE:To detect easily the abnormal fitting condition by using at least one conductor for connecting electricity which a connector and a cable have and forming a circuit for confirming the fitting condition of the connector and the cable. CONSTITUTION:An LED 7 is provided through a resistance 6 connected to an electric power source on a printing circuit plate 2. The LED 7 is connected through a printing conductor to a connecting conductor 8 in a cable 3,and earthed through a printing conductor on a printing circuit plate 1. Consequently, when connectors 4 and 5, and the cable 3 are ordinarily fitted, the LED 7 is emitted. On the other hand, when the connectors 4 and 5, or a cable 3 is not ordinarily fitted, the LED is not emitted.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to electrical devices (including electronic devices) using a plurality of connectors and cables, and particularly to a method for checking that these connectors and cables are properly attached. This invention relates to a method of configuring electrical equipment with connectors and cables having means for verifying.

[Conventional technology]

It is obvious that conventionally, many electrical devices are constructed using connectors and cables, but it is necessary to check whether these connectors and cables are properly attached and whether they have not come loose. and there was no means to detect it.

[Problems to be solved]

The above-mentioned conventional methods of configuring electrical equipment using connectors and cables do not have a means to detect disconnection or disconnection of cables or connectors, disconnection of cables, etc. due to vibration during transportation, human recreational operations, mistakes during repair, etc. There is a problem.

# In large electronic devices, such as computers and communication devices, the entire device is constructed by connecting multiple printed wiring boards and multiple devices with multiple connectors and cables. Therefore, it is difficult to easily detect disconnection or disconnection of cables and connectors. usually,
Such troubles are recognized as abnormalities in the entire electronic device, and in many cases are caused by built-in components (transistors, ice, etc.).
The problem is that it often takes a lot of time to discover the problem because it is mistakenly thought to be caused by a disorder.

[Means for solving problems]

The present invention has solved the above problem and is a round product, which uses at least one of the plurality of connecting conductors of the connector and cable to configure a circuit for checking the attachment state of the connector and cable, The circuit is used to confirm whether the mounting state is normal or not.

〔Example〕

Next, the example is shown in Figures 1 to 4 as a Kit! ! I will clarify.

Figures 1 and 2 are circuit diagrams of circuits to which the electrical device configuration method using connectors and cables according to the present invention is applied and the second embodiment, respectively, and Figures 3 and 4 are circuit diagrams of the electrical device configuration method described above, respectively. FIG. 4 is a circuit diagram of a circuit to which the third and fourth embodiments of the invention are applied.

In FIG. 1, 1 and 2 are printed circuit boards on which components such as an IC and a Ranjistau relay are mounted. 4 and 5 are connectors connected to each printed circuit board, and 3 is a cable connecting these connectors.

On the printed circuit board 2 there is a light emitting diode 7 via a resistor 6 connected to a +5 port voltage.

The light-emitting diode 7 is followed by a connecting conductor 8 in the cable via a printed conductor and is grounded via the printed conductor on the printed circuit board l). Therefore, if the connectors and cables 3 to 5 are properly attached, the light emitting diode 7 emits light. If the connector 4.5 or the cable 3 is not properly attached, the light emitting diode 7 will not emit light because the ground on the light emitting diode 7 and the printed circuit board l will be disconnected. In this embodiment, one electrical conductor is used: the connector 3 and the cable 4.5.

Next, the embodiment shown in FIG. 2 will be explained. Reference numerals 10 and 11 denote printed circuit boards, and both of these boards 10 and 11 are connected through connectors 13 and 14 and cables 12 and K. The current from +5 volts is connected to the connecting conductor 16 in the resistance 15° cable.
．． The light emission of the 0 light emitting diode 19 flowing through the connecting conductor 18 and the light emitting diode 19 in the printed conductor 17° cable indicates that these connectors 13, 14 and the cable 12 are correctly attached.

Next, the embodiment shown in Fig. 8g3 will be explained. In this example,
It is used in relatively large devices made up of multiple printed circuit boards. In the figure, backboard 20
There is a wiring bin 31 in the back connector 21.22 attached to the back connector 21.22.

Wires 100 and 105 are placed on the backboard 20 by wiring between the wiring bins 31 by soldering or wrapping electrical conductors.

Make 109 etc. Such wiring 100.

105 and 109 are connected to a plurality of printed circuit boards 23 and 2
It is already well known that a large device can be constructed by using a large number of devices within 4 hours. printed circuit board 23.24

28 can be inserted and removed, and both printed circuit boards 23 and 24 are connected through front cables 29 and 30 IC. A +5 volt power supply supplied from the outside passes through a wiring 100 to a resistor 101 in a printed circuit board 23, a light emitting diode 102, and so on. Connecting conductor 103 in front cable 29 Printed conductor 104 in printed circuit board 24. Wiring 105. Printed conductor 106 within printed circuit board 23. Front cable connection conductor 107 in the front cable 30. Printed conductor 108 within printed circuit board 24. It is grounded via wiring 109. Therefore, the pack connectors 21, 22° front connectors 25, 26, 27, 28, front cables 29, 30 are tightened and the printed circuit board 23.
24, the light emitting diode 102 emits light. If any one of these becomes disconnected, the light emitting diode 102 will not emit light.

Next, the embodiment shown in FIG. 4 will be explained. In this example,
This book shows when the configuration of the device changes depending on its application. In the figure, a printed circuit board 200 is always required for a certain application, and a printed circuit board 202 is required for another application. Therefore, depending on the type of application, connectors 203-206 and cables 207
, the printed circuit board connected from 2081C changes. This embodiment shows a case where a printed circuit board 201 is required but a printed circuit board 202 is not required.

Preset switches 252 and 257 are provided so that the circuits shown in other embodiments can function depending on whether or not a printed circuit board is connected.

In this embodiment, since the printed circuit board 201 is required, the preset switch 252 is an oven.
7 is closed. Therefore, the current from +5 volts flows through resistor 2509, light emitting diode 251, and cable 207.

It is obvious that a light emitting diode may be placed on each printed circuit board. Furthermore, it is self-evident that detection means and circuits other than one light emitting diode may be used. Although this embodiment uses a printed circuit board, it is obvious that this embodiment can also be applied to connectors and cables that connect a plurality of devices.
