The utility model discloses can concentrate the signal of 2 sensors to an M12 interface, reduce the wiring, also save the precast cable. The device can be placed nearby the sensor, and wiring and line checking are convenient. The waterproof and moistureproof device can be placed in a noisy field environment, and can be used for quickly connecting a plurality of sensors, so that the connection strength is reduced, the length of a sensor precast cable is shortened, and the cost is saved.

Description

Quick termination of sensor

Technical Field

The utility model relates to a termination, a quick termination of sensor specifically says so.

Background

The sensor is widely applied to the field of automatic control, and is the primary link for realizing automatic detection and automatic control. Many sensors currently interface electrically with an M12 connector.

The connection modes of the sensors which are widely applied at present are as follows: each sensor is plugged into the input module of the controller via a single-ended pre-cast cable with an M12 receptacle at one end. The precast cable is generally a four-core or five-core cable, and each sensor needs to be connected with a power line and a signal line. On the one hand, when the sensor is more, insert the cable in the master control cabinet also a lot, can make the wiring more complicated like this, master control cabinet internal wiring more, more in disorder. On the other hand, the sensor far away from the controller needs a long precast cable, so that the phenomenon of mixed connection is easy to occur, the cost and the wiring complexity are increased, and the overhauling difficulty is increased.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide a quick wiring device of sensor.

The utility model discloses a realize above-mentioned purpose, an electric quick termination, including shell and M12 joint, glass optical fiber reinforcement PA6 shell, sturdy and durable, grease proofing waterproof.

The M12 joint comprises a locking brass nickel-plated nut and 5 brass gold-plated contact pins, and the contact pins are placed on a TPU needle holder.

The label is attached right above each M12 joint, so that a user can conveniently mark the label.

LED lamps are arranged at the upper left and the upper right of each M12 joint and used as indicator lamps for judging whether sensor signals are connected or not.

The cable is a 19-core cable with a cross-sectional area of 0.5mm2 KVV. Wherein the 18 cores are cables with black and white numerical numbers on the inner core, and the numbers are 1-18. The other core is a yellow-green double-color wire which is used as a grounding wire. One end of the cable is connected to the terminal, and the other end of the cable is led out through the wire outlet.

The locking sealing joint is positioned at one end of the device and is used as a wire outlet hole of the cable. Its characteristics are a sealed coupling of area locking cable function, can lock the cable on the one hand, prevent that the cable is not hard up or even drops, and on the other hand can play dampproofing and waterproofing's effect.

The utility model has the advantages that: the utility model discloses can concentrate the signal of 2 sensors to an M12 interface, reduce the wiring, also save the precast cable. The device can be placed nearby the sensor, and wiring and line checking are convenient. The waterproof and moistureproof device can be placed in a noisy field environment, and can be used for quickly connecting a plurality of sensors, so that the connection strength is reduced, the length of a sensor precast cable is shortened, and the cost is saved. The LED indicating lamp is arranged, whether a signal exists in the sensor can be visually displayed, and the line can be more conveniently checked when abnormality occurs.

To sum up, the utility model has the advantages of simple structure, wiring convenience, easily check the line, dampproofing and waterproofing.

Drawings

The present invention will now be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, a quick termination of sensor, including shell 1, 8M 12 joint 2, 8 joints divide into two rows about, and 4 symmetric distributions in every row, bilateral symmetry distribute, 16 green LED pilot lamps 3, 21 binding post 4, 19 core cables 5, 8 labels 6.

In the above structure, the housing 1 is made of glass fiber reinforced PA6 housing. The M12 connector 2 and the LED indicator lamp are embedded on the shell. The label 6 is label paper and is attached to the shell 1, so that a user can record information conveniently. The wiring terminal 4 is arranged inside the shell 1, one end of the cable 5 is connected to the terminal, and the other end of the cable passes through the locking head 7 of the wire outlet and is led out.

+ V is the positive connection of the power supply, -1V is the negative connection of the power supply, and PE is the ground wire. No. 1 pin of each M12 interface is in short circuit with a + V pin, and a No. 3 pin is in short circuit with a-V pin, and 24V power is provided for the sensor. No. 5 contact pin and PE contact pin short circuit, be the earth connection. No. 2 contact pin and No. 4 contact pin are the signal line access point, can insert two sensor signals. An LED indicator lamp is connected between the No. 2 contact pin and the No. 3 contact pin of each M12 interface, an LED indicator lamp is connected between the No. 4 contact pin and the No. 3 contact pin, when the No. 2 contact pin is connected with a sensor, the corresponding LED lamp connected between the No. 2 and the No. 3 can be lightened as a signal connection indicator lamp. Similarly, when the No. 4 contact pin is connected with a sensor, the corresponding LED lamp connected between No. 4 and No. 3 can be lightened.

The above are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
