Description of drawings
Fig. 1 is the composition structural representation of flexible flat cable test jack of the present invention.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the composition structural representation of flexible flat cable test jack of the present invention, as shown in Figure 1, flexible flat cable test jack of the present invention comprises first jack body 10, second jack body 11, power supply 12 and pilot lamp 13, wherein, be provided with the jack/plug corresponding with the plug/jack of described flexible flat cable on described first jack body 10 and second jack body 11; In this example, the jack/plug on first jack body 10 and second jack body 11 is 8, and the plug/jack on the corresponding flexible flat cable also is 8.Need to prove that Fig. 1 only is synoptic diagram, is not for limiting technical scheme of the present invention.It will be appreciated by those skilled in the art that when the plug/jack number on the flexible flat cable to be tested changes corresponding adjustment of first jack body 10 in the test jack among the present invention and the number of the jack/plug on second jack body 11 gets final product.
As shown in Figure 1, by cable jack/plug correspondence is separately connected between first jack body 10 and second jack body 11, be serially connected with pilot lamp 13 on the jack/plug connection cable between first jack body 10 and second jack body 11; Power supply 12 is connected between the jack/plug of first jack body 10 and second jack body 11.
Concrete, n jack/plug on first jack body 10 is connected by cable with n+2 jack/plug on second jack body 11, m jack/plug on first jack body 10 is connected by cable with m-2 jack/plug on second jack body 11, wherein, n is odd number, and m is the even number greater than 2.
When the total jack/plug on the jack body (first jack body 10 and second jack body 11) was counted p and is even number, p-1 jack/plug on first jack body 10 was connected by cable with p jack/plug on second jack body 11; When the total jack/plug on the jack body was counted p and is odd number, p jack/plug on first jack body 10 was connected by cable with p-1 jack/plug on second jack body 11.
The 1st jack/plug of first jack body 10 and the 3rd jack/plug of second jack body 11 link to each other, the 3rd jack/plug of first jack body 10 and the 5th jack/plug of second jack body 11 link to each other, the 5th jack/plug of first jack body 10 and the 7th jack/plug of second jack body 11 link to each other, and the 7th jack/plug of first jack body 10 and the 8th jack/plug of second jack body 11 link to each other.
The 2nd jack/plug of first jack body 10 and the 4th jack/plug of second jack body 11 link to each other, the 4th jack/plug of first jack body 10 and the 6th jack/plug of second jack body 11 link to each other, and the 6th jack/plug of first jack body 10 and the 8th jack/plug of second jack body 11 link to each other.
And power supply 12 is connected between the 1st jack/plug of the 2nd jack/plug of first jack body 10 and second jack body 11.
Why flexible flat cable test jack of the present invention adopts this connected mode, the characteristics of having considered flexible flat cable design, opening circuit of cable may appear on each plug/jack in the flexible flat cable, but short circuit only may appear on the line between two adjacent plug/jack, between plug/ jack 1,2, between the plug/ jack 2,3 etc.Use intersection winding design circuit as shown in Figure 1, can determine the line fault situation of flexible flat cable quickly.
As shown in Figure 1, flexible flat cable test jack of the present invention also comprises current-limiting resistance 14, is serially connected with in the cable that connects power supply 12.Current-limiting resistance 14 among the present invention can also be avoided causing in the test jack of the present invention electric current excessive owing to power supply 12 both positive and negative polarities directly are connected, thereby avoid flexible flat cable and test jack of the present invention are burnt when flexible flat cable short circuit to be measured.Pilot lamp 13 among the present invention, as shown in the figure, on last jack/plug that is serially connected with first jack body 10 and the connecting line of second jack body, 11 corresponding jack/plug.
Need to prove that first jack body 10 among the present invention and the structure of second jack body 11 all are identical, just be the needs of interest of clarity, just set " first " and reached " second "; The sortord of the jack/plug shown in the figure also can be the order from " 8 " to " 1 ".
Below based on flexible flat cable test jack shown in Figure 1, further illustrate the method for testing of flexible flat cable of the present invention.
As shown in Figure 1, the plug/jack at the two ends of flexible flat cable to be tested is inserted into respectively in the corresponding jack/plug in first jack body 10 and second jack body 11.When the plug/jack at flexible flat cable two ends is inserted in the corresponding jack/plug in first jack body 10 and second jack body 11 respectively, flexible flat cable is with first jack body 10 and identical corresponding connection of plug/jack of second jack body, 11 numberings, link to each other as the plug/jack of first jack body 10 and the plug/jack of second jack body 11, like this, at first jack body 10 and second jack body 11, namely constituted multiple ring between the flexible flat cable, whether luminous by the pilot lamp that arranges on the cable, can determine flexible flat cable and whether have short circuit or open circuit fault.
Why flexible flat cable test jack of the present invention adopts this connected mode, the characteristics of having considered flexible flat cable design, opening circuit of cable may appear on each plug/jack in the flexible flat cable, but short circuit only may appear on the line between two adjacent plug/jack, between plug/ jack 1,2, between the plug/ jack 2,3 etc.Use intersection winding design circuit as shown in Figure 1, can determine the line fault situation of flexible flat cable quickly.
Start power supply 12, whether determine on the connection cable between the jack/plug on first jack body 10 and second jack body 11 pilot lamp 13 to be set luminous, if all luminous, illustrate then not have short circuit or breaking phenomena in the flexible flat cable to be tested that flexible flat cable to be tested is specification product; Otherwise, namely illustrate to have short circuit between the winding displacement in the flexible flat cable to be tested or open circuit, do not meet the standard of dispatching from the factory.
For example: the plug/ jack 4,5 of flexible flat cable has caused short circuit in manufacturing process.The flexible flat cable two ends are inserted in respectively in the accompanying drawing 1 on first jack body 10 and second jack body 11, because plug/ jack 4,5 is connected on "+" and "-" two ends of power supply respectively, the plug/jack that can cause the back so i.e. short circuit between the plug/ jack 6,7,8 of first jack body 10 and second jack body 11, causes the pilot lamp 13 shown in the figure can be not luminous.
If open circuit between any plug/jack of flexible flat cable, because entire circuit is connected in series, entire circuit will open circuit, and pilot lamp also can be not luminous.
The above is preferred embodiment of the present invention only, is not for limiting protection scope of the present invention.
