Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector,
More specifically, the present invention relates to a connector connected to a detector such as a photomicrosensor.

[0002]

2. Description of the Related Art In many cases, an optical ON / OFF sensor, for example, a photomicrosensor, selectively uses an output mode that is turned on when light is blocked and an output mode that is turned on when light is incident, depending on the logical configuration during use. It is configured so that one photomicrosensor can cope with the two output modes.

[0003] As the photo-microsensor to accommodate two such output forms, for example, as shown in FIG. 16, a power source + (plus) terminal 15 _1, the output switching terminal 1
5 _2, and the output terminal 15 _3, power - (minus) terminal 15
With four terminals and _4, usually the output switching terminal 15 ₂ is open, the output mode of ON during the light-shielding, light incident by shorting power + terminal 15 ₁ and the output switching terminal 15 ₂ First type photomicrosensor 16 configured to be switched to an output mode that is turned on at the time
Comprises four terminals of the terminal 17 ₄ - When, as shown in FIG. 17, a power supply + terminal 17 _1, and the output terminal 17 ₂ to ON at the time of light incidence, and the output terminal 17 ₃ to ON at the time of light blocking, power There is a second type of photomicrosensor 18.

On the other hand, these photomicrosensors 16,
18 conventional connector 20 which is connected, as shown in FIG. 18, has four terminals 19 ₁ to 19 ₄ corresponding respectively to the four terminals of the photo micro sensor 16, 18. There is also a type in which four lead wires are drawn out of the main body of the connector 20 instead of the terminals 19 _{1 to} 19 ₄ .

[0005]

In the actual use state of the photomicrosensor, as described above, the photomicrosensor is used in one of the output states of ON at the time of light blocking and ON at the time of light input. When connecting the photo micro sensor connector and, in order to obtain a desired output form, connection or selected according to the terminal 19 ₁ to 19 ₄ or leads the alternative connector 20 of the type of the photo microsensor I do.

Namely, in the first type of photo micro sensor 16 of FIG. 16, in order to output form to ON when light incident, it is necessary to short-circuit the power supply + terminal 15 ₁ and the output switching terminal 15 ₂ The connector 20 to do so
It is necessary to short-circuit the terminals 19 ₁ and 19 ₂ or to replace the ends of the lead wires instead. On the other hand, in order to set the output mode to be ON when light is blocked,
Since the output switching terminal 15 ₂ is required to be opened,
So as not to touch accidentally the tip of the terminal 19 ₂ or its substitute lead connector 20 to the power supply line or the like which are necessary processing such as covering the insulating cover. When the conventional connector 20 is used, these processes are troublesome. Also, in the case of a connector of a type from which a lead wire is drawn out, although the photomicrosensor is used while being fixed to one of the output forms,
A lead wire having a length of several meters is used only for determining the output form, which is not preferable from the viewpoint of effective utilization of resources.

[0007] In the second type of photo micro sensor 18 of FIG. 17, since there are both the output of the light-shielding time of ON and Incident ON, use of the terminals 19 ₂ and 19 ₃ of the connector 20 corresponding to these It is necessary to cover the terminal which is not to be used or the tip of the lead wire which is to be replaced with an insulating cover. When the conventional connector 20 is used, this process is troublesome. Also, in the case of a connector with a lead wire drawn out, the unused output wire can be cut off at the portion close to the connector body and discarded, or simply fixed at an appropriate place without cutting it. It was a waste of resources.

[0008] The above situation is the same for a photoelectric sensor, a proximity sensor, and other connectors used in connection with other detectors whose output form can be selected in the same manner as the photomicrosensor described here.
