The suspending arm ends of the contacts are kept at a distance to the supporter, so as to allow the test LED to be received therein. The two contacts are both connected with wires fitted inside the supporter. The wires are directed out of the fixture to ensure the test signals to be sent to a measurement apparatus.
Description
Technical field
The utility model relates to a kind of measured material of electronic devices and components, specifically is the anchor clamps that adopt when measuring large-power light-emitting diodes.
Background technology
Along with development of modern science, the use of large-power light-emitting diodes is more and more general.And large-power light-emitting diodes all need be measured before dispatching from the factory or selecting for use.Present large-power light-emitting diodes is because aluminium base need all be equipped with in heat radiation, and electrode contacts and luminous point are in again with on the one side; Because do not have unit clamp when measuring, thereby can only be flat on diode on the table top, two route levers of the hand-held survey instrument of operating personnel are aimed at and are connected two of diode and touch the utmost point then, and then draw measurement data.This kind mode inefficiency, inconvenience be easy to generate measuring error, and test process is comparatively loaded down with trivial details to tested large-power light-emitting diodes location.
The utility model content
The purpose of this utility model provides a kind of High-power luminescent diode measurement clamp, these anchor clamps should be able to overcome the deficiency of above-mentioned background technology, have positioning requirements simple in structure, as to be easy to adapt to various measurements, measure the characteristics that quality is good, efficiency of measurement is high, easy and simple to handle.
The technical scheme that the utility model proposes is:
High-power luminescent diode measurement clamp is provided with a track in its support, and is equipped with the motion block that can slide along this orientation of orbit, and other has a spring to be located between motion block and the support and forces in motion block and support respectively; The both sides of described support also be respectively equipped with one be used to be electrically connected touch the utmost point, these two cantilever ends that touch the utmost point are overhung at the top of motion block and extend to the other side mutually, and two are touched the utmost point and keep some distances to realize well contacting with two electrodes of large-power light-emitting diodes and being convenient to the clamping measured diode; The described cantilever end that touches the utmost point also keeps suitable spacing with support so that the putting into of measured diode; Described two are touched the utmost point and connect the lead be located in the support again respectively, and this lead is drawn the anchor clamps outside again, so that surveying instrument is delivered in measured signal.
Track on the described support is an inner cylinder face, and motion block then is shaped on its matched external cylindrical surface and contacts with the good of potential electrode with the orientation slip of realization motion block and two electrodes of light emitting diode.
Described motion block adopts the metal material that is easy to dispel the heat to make.
The lower end of described support also can be made into the step shape of being convenient to test position fix.
Adopt the utility model, the surveying work of light emitting diode just becomes, and very simple-only with hand presses down motion block-will touch the cantilever end of the utmost point slightly and the space between the support is vacateed, insert tested light emitting diode then and keep it and touch being electrically connected of the utmost point, loosing one's grip afterwards gets final product; Spring force can firmly be clamped in light emitting diode two and touch between extreme and the motion block, and measured signal is then delivered to surveying instrument by touching the utmost point, and measurement data can obtain.In addition, the motion block of metal material making also has heat sinking function; The step shape of anchor clamps lower end can make it be positioned easily on the testing tool again, and to adapt to the positioning requirements of various measurements, not only operation is very easy, and efficiency of measurement significantly improves, and is difficult for producing measuring error, has guaranteed the measurement quality effectively; In addition, the structure of these anchor clamps is also very simple, easy to manufacture, with low cost.

Fig. 3 is a user mode synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, High-power luminescent diode measurement clamp has support 5, and a track is set in the support, and is equipped with the motion block 4 that can slide along this orientation of orbit.Among the figure as can be known: the inner cylinder face of a rule is arranged, the outer circumference surface of motion block and its fit in the support; The face of cylinder is the required track of motion block slippage.Obviously, described track also can adopt other multiple structure (as rectangular cylinder or polygon cylinder), as long as motion block has the linear slide one degree of freedom, can realize the directed slip application of force of motion block, thereby two electrodes of realizing large-power light-emitting diodes are realized well contacting with potential electrode.
Among the figure also as can be known: the bottom of motion block is shaped on inner concavity, and other has a spring 3 to be embedded in wherein, and forces in the bottom of motion block and the end of support inner cylinder face respectively, the potential energy that motion block is had move up.This motion block also can adopt metal material (as aluminium or copper) to make, and contacts with the aluminium base radiating surface of tested light emitting diode when test, also plays heat sinking function when motion block is played the role of positioning.
The both sides of described support also be respectively equipped with one be used for measuring electrical connection touch the utmost point 1 (figure is fixing with screw 2), these two are touched the top that the utmost point is overhung at motion block, two cantilever end 1-1 that touch the utmost point also extend near some distances to the other side mutually, this distance should adapt with two electrode distances of large-power light-emitting diodes, contacts with the good of electrode so that keep touching the utmost point; Guarantee that again measured diode can be gripped reliably by cantilever end and motion block; Two cantilever end 1-1 that touch the utmost point keep suitable spacing with support again, and this spacing should be greater than the thickness of measured diode, so that the insertion of measured diode.The described utmost point that touches is also connected the lead of being located in the support 7, and this lead extends to the bottom of support again, so that measured signal causes surveying instrument.
In addition, the lower end 6 of support 5 also can be made into suitable step shape, works so that be positioned on the needed testing tool.
