Description

Plug socket power line detector

Technical field

The utility model relates to a kind of plug socket detection device, is meant a kind of plug socket power line detector especially.

Background technology

At present, in plug socket assembling process, after power lead is gone up in the core body assembling, need whether connect the polarity of each heart yearn of power lead correctly, and need detect.Because the heart yearn of opposed polarity adopts the crust of different colours, under the normal condition, the red-black green three look heart yearns of triple-pole type plug socket connect positive pole, negative pole and earthing pole respectively.During assembling, heart yearn of all kinds also is to arrange in order, usually check just during detection whether whether the color alignment order consistent with the order of design, unanimity then represents the power lead wiring correct, otherwise wiring error then, this manual detection mode, detection person's labour intensity is big, and easily makes that because of fatigue causes carelessness detection is inaccurate.

And adopt technology that laser distinguishes between colors comparative maturity, its principle is: by generating laser emission laser scanning object under test, and receive the laser reflect, distinguish that by one the look circuit determines the surface color of object under test according to the optical characteristics of the laser that reflects again.Yet, also do not have at present the look technology of distinguishing of this maturation is applied to the device that plug socket power line detects.

The utility model content

Technical problem to be solved in the utility model is: a kind of plug socket power line detector is provided, can reduces and detect labour intensity, and the detection misalignment of avoiding human negligence to cause, and have high-reliability.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of plug socket power line detector is provided, comprises for the fixing half-finished holder of plug socket to be measured, at least two laser probes and testing circuit.Be provided with Laser emission and receiver in each laser probe, distinguish the look circuit; Testing circuit comprises Programmable Logic Controller and is connected to comparator circuit and warning circuit on the Programmable Logic Controller that warning circuit is connected to alarm; Two laser probes scan the positive pole of the semi-manufacture power supply line that is fixed on the holder and the heart yearn of negative pole respectively, record color signal and are transferred to comparator circuit and produce one respectively; Comparator circuit will record Standard Colors default in color signal and the Programmable Logic Controller and compare, and then start warning circuit as difference and report to the police.

The beneficial effects of the utility model are: record Standard Colors default in color signal and the Programmable Logic Controller and compare in proper order by adopting laser probe to distinguish the heart yearn color of plug socket semi-manufacture power supply line and producing one, then can start warning circuit as difference reports to the police with prompting detection person wiring error, realized the mechanization detection, detection person's labour intensity reduces greatly, and the detection misalignment of effectively having avoided human negligence to cause, the fiduciary level height.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of drawings

Fig. 1 is the structural representation of the utility model plug socket power line detector.

Fig. 2 is that the semi-manufacture of the utility model plug socket power line detector are installed on the vertical view on the holder.

Fig. 3 is the circuit theory diagrams of the utility model plug socket power line detector.

Embodiment

In first embodiment as shown in Figure 1 to Figure 3, the utility model provides a kind of plug socket power line detector, comprises for the half-finished holder of fixing plug socket to be measured 1, three laser probes 2 and testing circuits 3.

Wherein, holder 1 is provided with for the fixing installation position of semi-manufacture.

Described three laser probes 2 are located at three sides of installation position on the holder 1 and respectively over against the heart yearn 901,902,903 that is fixed in half-finished power lead 90 positive poles on the holder 1, negative pole, earthing pole, are provided with Laser emission and receiver 21 in each laser probe, distinguish look circuit 22.The technology that laser distinguishes between colors belongs to ripe prior art, at this its structure and principle is seldom described.

As shown in Figure 3, described testing circuit 3 comprises Programmable Logic Controller 31 and is connected to comparator circuit 32 and warning circuit 34 on the Programmable Logic Controller 31 that warning circuit 34 is connected to alarm 341.Described alarm 341 can adopt hummer or loudspeaker or warning lamp.Described testing circuit also can comprise and is connected on the Programmable Logic Controller 31 display screen 35 that detects comparative result to show.

When detecting, established standards color on Programmable Logic Controller 31 in advance, for example, the Standard Colors of setting is for just very white, negative pole are that black, ground connection are very green.Then, start described three laser probes 2 and launch the heart yearn 901,902,903 that positive pole, negative pole and the earthing pole of the semi-manufacture power supply line 90 on the holder 1 are fixed in laser scanning respectively, and respectively by distinguishing that look circuit generation one records color signal and is transferred to comparator circuit 32; Comparator circuit 32 compares the Standard Colors default in color signal and the Programmable Logic Controller 31 that records of each utmost point, then starts warning circuit 33 as difference and reports to the police.

The utility model plug socket power line detector also can comprise a board 4 that supplies above-mentioned each assembly to be mounted thereon.

In addition, in another embodiment of the present utility model, installation position on the described holder 1 is the installation position for installation diarch plugs and sockets, laser probe 2 is then corresponding to change two into, and described two laser probes 2 are located at two sides, installation position of holder 1 respectively and are corresponding with the heart yearn 901,902 at positive and negative the two poles of the earth of diarch plugs and sockets.

The utility model records Standard Colors default in color sequences and the Programmable Logic Controller 31 and compares in proper order by adopting laser probe 3 and distinguish the heart yearn color of the half-finished power lead 90 of plug socket and producing one, then can start warning circuit 34 as difference reports to the police with prompting detection person wiring error, realized the mechanization detection, detection person's labour intensity reduces greatly, and the detection misalignment of effectively having avoided human negligence to cause, the fiduciary level height.
