Abstract

The utility model relates to a converter-equipped reverse connection-proof plug and plug seat combination in an LED light. Four surface plug holes of a conventional plug seat are arranged as four end points at upper and lower sides of a trapezoid which is provided with a wide upper part and a narrow lower part. Plug pins are also designed as four end points at upper and lower sides of a corresponding trapezoid. Therefore the plug and plug seat matching mode is fixed, and LED reverse polarity connection can be prevented. A converter which can convert the AC12V into a current source or a voltage source is arranged in the plug, an AC12V current enters the inside of the plug from two pins of the upper side or the lower side of the plug trapezoid, and the AC12V current enters the inside of the plug seat from two pins of the lower side or the upper side of the trapezoid and is supplied to the LED after being converted into a current source or voltage source current with polarity.

Description

The anti-reverse plugs and sockets combination of LED

Technical field

The utility model relates to a kind of LED lighting, specifically refers to the anti-reverse plugs and sockets combination of a kind of LED.

Background technology

In the LED light fixture, if change original AC12V power supply into the transducer power supply, output is direct current with polarity, and the plug and socket of conventional arrangement is the plug and socket be used to the alternating current that there is no polarity, so just is easy to occur the phenomenon of LED reverse polarity connection.

Summary of the invention

In view of this, in order to address the above problem, this is novel provides a kind of simple in structure, uses reliable and secure socket and the plug that can prevent again the LED reverse polarity connection with the transducer while.For achieving the above object, the utility model adopts following technical scheme:

Traditional socket table face is changed into wide at the top and narrow at the bottom trapezoidal, 4 jacks of described socket are set to respectively trapezoidal four following end points, and described plug pin also is designed to corresponding trapezoidal four following end points.The mode of plug and socket coupling is fixed like this, just can prevent the LED reverse polarity connection.Plug inside is provided with and AC12V can be converted into the transducer of current source or voltage source, the AC12V electric current from the trapezoidal top of plug or 2 following pins enter plug inside, through being converted into after the current source of polarity or voltage source electric current from trapezoidal below or 2 pins of top enter socket internal feed LED and use.

Preferably, the transducer of plug and back can be coupled together with flexible conductor, just it goes without doing in same cavity for plug and transducer like this, and volume can diminish, and adapts to better the different installation occasion of LED.The pin that simultaneous converter met AV12V originally also can change the ordinary plug that flexible conductor connects into, and the socket of traditional output AC12V coupling.In 4 pins of plug, the pin of being responsible for input current is vacant at this moment.

After adopting technique scheme, in use, can prevent the LED reverse polarity connection with the plug of transducer.Compare with existing product, this is novel, simple in structure, and institute takes up space little, easy to use, has well satisfied the needs of the multiple supply power mode of Novel LED lamp.

Fig. 2 is the schematic diagram of the anti-reverse plugs and sockets combination of a kind of LED of the utility model embodiment 2.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Embodiment 1:

With reference to figure 1, the utility model discloses the anti-reverse plugs and sockets combination of a kind of LED, 4 jacks of described socket form respectively trapezoidal four following end points, and described plug pin also forms trapezoidal four following end points.The mode of plug and socket coupling is fixed like this, just can prevent the LED reverse polarity connection.Plug inside is provided with and AC12V can be converted into the transducer of current source or voltage source, the AC12V electric current from the trapezoidal top of plug or 2 following pins enter plug inside, through being converted into after the current source of polarity or voltage source electric current from trapezoidal below or 2 pins of top enter socket internal feed LED and use.

Embodiment 2:

With reference to figure 2, the transducer of plug and back is coupled together with flexible conductor, just it goes without doing in same cavity for plug and transducer like this, and volume can diminish, and adapts to better the different installation occasion of LED.The pin that simultaneous converter met AV12V originally also can change the ordinary plug that flexible conductor connects into, and the socket of traditional output AC12V coupling.In 4 pins of plug, the pin of being responsible for input current is vacant at this moment.

The above; it is only the better embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.

Claims

1. anti-reverse plugs and sockets combination of LED, it is characterized in that: 4 jacks of described socket are set to respectively trapezoidal four following end points, and described plug pin also is designed to corresponding trapezoidal four following end points, and described plug inside is provided with transducer.

2. the anti-reverse plugs and sockets combination of a kind of LED as claimed in claim 1, it is characterized in that: described plug and transducer are coupled together with flexible conductor, and described transducer connects ordinary plug with flexible conductor.
