Abstract
The invention discloses a kind of winding displacement check device.The binding post, electric wire, power supply, indicator lamp；The binding post two ends are respectively arranged with power supply, indicator lamp, and the both positive and negative polarity of the power supply is corresponding with indicator lamp both positive and negative polarity, and the wiring intercolumniation is connected by electric wire；When the both positive and negative polarity of power supply is connected correct with the binding post electric wire of the positive and negative interpolar of indicator lamp, indicator lamp lights, and on the contrary then indicator lamp does not work.The present invention can intuitively judge whether winding displacement connection is correct using indicator lamp, it is to avoid occur because winding displacement mistake causes short circuit so as to damage the situation of chip.
Description
Technical field：
The invention belongs to chip testing technology field, more particularly to a kind of winding displacement check device.
Background technology：
Chip in test process, the wiring error that winding displacement usually occurs cause short circuit situation occur, chip can because
Short circuit and damage, cause unnecessary loss.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention：
It is an object of the invention to provide a kind of winding displacement check device, so as to overcome above-mentioned defect of the prior art.
To achieve the above object, the invention provides a kind of winding displacement check device, including：Binding post, electric wire, power supply, refer to
Show lamp；The binding post two ends are respectively arranged with power supply, indicator lamp, and the both positive and negative polarity of the power supply is relative with indicator lamp both positive and negative polarity
Should, the wiring intercolumniation is connected by electric wire；When the both positive and negative polarity of power supply is connected just with the binding post electric wire of the positive and negative interpolar of indicator lamp
When really, indicator lamp lights, and on the contrary then indicator lamp does not work.
Preferably, in technical scheme, power supply selects 5V power supplys.
Compared with prior art, the present invention has the advantages that：
Can intuitively judge whether winding displacement connection correct using indicator lamp, it is to avoid because winding displacement mistake cause short circuit from
And the situation for damaging chip occurs.
Brief description of the drawings：
Fig. 1 is winding displacement check device structural representation of the present invention；
Reference is：1- binding posts, 2- electric wires, 3- power supplys, 4- indicator lamps.
Embodiment：
The embodiment to the present invention is described in detail below, it is to be understood that protection scope of the present invention is not
Limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, winding displacement check device, including：Binding post 1, electric wire 2,5V power supplys 3, indicator lamp 4；The binding post 1
Two ends are respectively arranged with 5V power supplys 3, indicator lamp 4, and the both positive and negative polarity of the 5V power supplys 3 is corresponding with the both positive and negative polarity of indicator lamp 4, described to connect
Connected between terminal 1 by electric wire 2；When the both positive and negative polarity of 5V power supplys 3 is connected correctly with the electric wire 2 of binding post 1 of the positive and negative interpolar of indicator lamp 4
When, indicator lamp 4 lights, and on the contrary then indicator lamp 4 does not work.It can intuitively judge whether winding displacement connection is correct using indicator lamp 4,
Avoid and occur because winding displacement mistake causes short circuit so as to damage the situation of chip.
It is foregoing to the present invention specific illustrative embodiment description be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles and its reality of the present invention should
With so that those skilled in the art can realize and using the present invention a variety of exemplaries and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
Claims (2)
