Description

Keyboard lamp hole detects jig

Technical field

The utility model relates to arrive laptop peripheral technologies field, and in particular to a kind of keyboard lamp hole detection jig.

Background technique

It is also most important input equipment that keyboard, which is presently most used, to input text, symbol or number.Not only such as This, as long as the consumer electrical product or the large-sized processing equipment that uses of industry of everyday life contact, all need to be equipped with by Bond structure is as input unit, to operate above-mentioned electronic product and process equipment.

In the production of keyboard of notebook computer, need to carry out translucency inspection to each indicator lamp hole on keyboard of notebook computer It surveys, it is whether qualified to judge keyboard product, but lack a kind of special fixture in the prior art, majority holds keyboard case to be artificial It is detected against intense light source, in this way first is that large labor intensity, detection efficiency is low, for a long time against strong light, fatiguability makes human eye The accuracy for obtaining testing result cannot be guaranteed.

Summary of the invention

In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of keyboard lamp holes to detect jig, can facilitate Realization keyboard lamp hole detection, help to improve the accuracy of production efficiency and testing result.

In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:

A kind of keyboard lamp hole detection jig, key are: including detection plate, offering in the front of the detection plate more A mounting hole, and the position of the mounting hole and keyboard lamp hole to be detected is adapted, and is installed with LED in each mounting hole Lamp bead is further fixed on power connection and limited block in the front of the detection plate, and the limited block is distributed in the detection plate Arbitrary neighborhood two sides, and the LED lamp bead and power connection are located at the medial and lateral that the limited block surrounds region, in institute The back side for stating detection plate offers wiring groove, is laid with conducting wire in the wiring groove, one end of the conducting wire and the power connection It is electrically connected, multiple LED lamp beads are sequentially connected in series by the other end of the conducting wire.

Further, the wiring groove includes set section, linkage section and wire segment, and the set section is described for placing Power connection, for the linkage section for realizing the connection between set section and wire segment, the wire segment is used for device for each LED The concatenated conducting wire of lamp bead.

Further, the wire segment is in L-shaped, junction and the linkage section phase of the lateral part with vertical section Connection.

Further, the middle part on front side of the detection plate is also provided with pickup mouth, and the LED lamp bead is distributed in the pickup The left side of mouth and rear side.

Further, the limited block is distributed in left side and the rear side of the detection plate, and the folder between two limited blocks Angle is right angle.

Further, the conducting wire is tightly attached to the bottom of the wiring groove by bond pad.

The remarkable result of the utility model is: structure is simple, novel in design, by the way that keyboard upper housing is placed in limited block In the region of formation, the power supply of LED lamp bead is connected, light is just appeared from the lamp hole on keyboard, can be examined by human eye at this time Whether the lamp hole surveyed on keyboard is qualified, and easily laborsaving, detection efficiency and accuracy are all very high.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the rearview of the utility model.

Specific embodiment

Specific embodiment of the present utility model and working principle are described in further detail with reference to the accompanying drawing.

As shown in Figures 1 and 2, a kind of keyboard lamp hole detects jig, including detection plate 1, opens in the front of the detection plate 1 Equipped with multiple mounting holes, and the position of the mounting hole and keyboard lamp hole to be detected is adapted, and is filled in each mounting hole Equipped with LED lamp bead 2, it is further fixed on power connection 3 and limited block 4 in the front of the detection plate 1, the limited block 4 is distributed in The arbitrary neighborhood two sides of the detection plate 1, and the LED lamp bead 2 and power connection 3 are located at the limited block 4 and surround area The medial and lateral in domain offer wiring groove 5 at the back side of the detection plate 1, are laid with conducting wire 6 in the wiring groove 5, the conducting wire 6 One end and the power connection 3 be electrically connected, multiple LED lamp beads 2 are sequentially connected in series by the other end of the conducting wire 6, and The conducting wire 6 is tightly attached to the bottom of the wiring groove 5 by bond pad 8.

From figure 2 it can be seen that the wiring groove 5 includes set section 51, linkage section 52 and wire segment 53, the accommodating Section 51 is for placing the power connection 3, and the linkage section 52 is for realizing the connection between set section 51 and wire segment 53, institute It states wire segment 53 and is used for device for the concatenated conducting wire 6 of each LED lamp bead 2.Preferably, the wire segment 53 is in L-shaped, transverse part Divide and is connected with the junction of vertical section and the linkage section 52.Using above-mentioned design, the power supply that can will test 1 back side of plate is connect First 3, conducting wire 6 etc. is all placed in wiring groove 5, so that this detection jig can be a horizontal plane when detecting, from And facilitate observation keyboard lamp hole whether qualified, erroneous detection caused by effectively preventing because of tilt angle problem or false retrieval phenomenon.

It can also be seen that being also provided with pickup mouth 7, the LED at the middle part of 1 front side of detection plate from Fig. 1 and Fig. 2 Lamp bead 2 is distributed in left side and the rear side of the pickup mouth 7, by the pickup mouth 7 facilitate keyboard case before detection after blowing with Feeding, to further accelerate working efficiency.

In the present embodiment, the limited block 4 is distributed in left side and the rear side of the detection plate 1, and between two limited blocks 4 Angle be right angle, to easily be positioned to two right-angle sides of keyboard, it is ensured that the accuracy of testing result.

When being detected using this jig, keyboard top cover shell is placed in detection plate 1 first, and passes through limited block 4 It is positioned, then power supply line is connected with power connection 3, LED lamp bead 2 shines, and passes through each lamp hole of eye-observation keyboard Light transmission situation, to reduce labor intensity, improve detection efficiency you can learn that whether lamp hole qualified.

When detecting, the power supply of LED lamp bead 2 can also be continuously turned on, then continues keyboard being placed in detection plate 1 enterprising Row detection, the power cutoff again after the lasting detection of a batch or a period, so that detection efficiency is further promoted, Also avoid frequently switching on that power cutoff causes LED lamp bead 2 benefits from the lost of life.
