Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The utility model embodiment provides a kind of test probe, and this test probe comprises base, elastic telescopic element and probe, and described probe is arranged on described base by described elastic telescopic element.
Wherein, the cross sectional shape of above-mentioned base can be L shape, as shown in Figure 2, this test probe comprises base 1, elastic telescopic element 3 and the probe 2 that cross sectional shape is L shape, wherein, this cross section is that the base 1 of L shape comprises transverse part 1a and longitudinal part 1b, and one end of this elastic telescopic element 3 is connected to transverse part 1a, and the other end of elastic telescopic element 3 is connected to described probe 2.
Wherein, above-mentioned elastic telescopic element 3 can be spring or other elements made by resilient material, probe 2 is connected with the signal lines 200 of optical device, as shown in Figure 3, before test, can at the test zone coating elargol 300 of liquid crystal display 100, then mobile test probe makes the needle point of probe 3 move to the overlying regions of coating elargol, the needle point of probe penetrates in the elargol of coating under the effect of elastic telescopic element 3, thus completes the connection of optical device and tested liquid crystal display.
Preferably, as shown in Figure 2, when testing, the needle point place 2c of described needle section and the bottom surface 1c of described base 1 is positioned at same level, thus is conducive to when testing, the needle point of probe being penetrated in the test zone of liquid crystal display smoothly.
In addition, penetrate the degree of test zone when testing in order to improve needle point, improve the reliability connected, when testing, probe 2 is contacted with base 1 by the pulling force of elastic telescopic element 3, and namely elastic telescopic element is in when testing the state of being stretched, and when testing, elastic telescopic element 3 is stretched further, thus increases the pulling force suffered by probe, and then improves the degree that needle point penetrates test zone.
Preferably, as shown in Figure 4, probe 2 to be arranged on described base 1, by arranging multiple elastic telescopic element by the plurality of elastic telescopic element 3, pulling force suffered when greatly can improve probe test, thus the degree improving that probe penetrates test zone further.
The test probe that the utility model embodiment provides, only need in advance at the test zone coating elargol of liquid crystal display, and no longer need to make the step such as solder stick, fixing solder stick, therefore the preliminary work before test can not only greatly be simplified, the reliability connected can also be ensured, thus substantially reduce the test duration, improve testing efficiency.
