For allowing above-mentioned purpose of the present invention, feature and advantage become apparent, preferred embodiment of the present invention cited below particularly, and conjunction with figs. are described in detail below:
Please also refer to Fig. 1 and Fig. 2 A, Fig. 1 is the exploded perspective view of test head of press key tester preferred embodiment of the present invention; Fig. 2 A is the assembled sectional view of test head of press key tester preferred embodiment of the present invention; Test head of press key tester of the present invention comprises a holder 10, a screwed pipe 20, a reference test bar 30, a briquetting 40, an adjustment nut 50 and a hold-doun nut 60.Holder 10 1 sides are provided with a joint portion 11, and joint portion 11 is in order to combine with the movement arm (not illustrating) of a key testing machine, and movement arm drives reciprocating by key testing machine; Joint portion 11 can form C type groove or other combinative structure such as dovetail groove as shown in the figure, holder 10 tops are provided with a fixed orifice 15 and are communicated with joint portion 11, when joint portion 11 is combined in movement arm, is screwed into fixed orifice 15 by a fixed screw 16 and shores movement arm and make and become firm combination.
Screwed pipe 20 outsides have screw thread 21, and the center is provided with the through hole 22 that connects screwed pipe 20, and through hole 22 is inserted for a reference test bar 30 and a spring 25, and there is a lower surface 26 bottom of screwed pipe 20.The upper/lower terminal of through hole 22 is fixed a head bearing 23, a lower bearing 24 with wringing fit or gummed mode respectively, and reference test bar 30 can slide in through hole 22 smoothly by the support of upper and lower bearing 23,24.Upper and lower bearing 23,24 can be that stone mill, copper, plastics, pottery or the materials such as alloy with pore are made.
The combined hole 41 that reference test bar 30 is provided with first end 31, second end, 32, the first ends 31 and a briquetting 40 is to screw togather or mode such as gummed combines, and briquetting 40 is made for rubber-like materials such as rubber, silica gel, its in order to be tested by key contacts.Be provided with a bulge loop 33 between first end 31 and second end 32, reference test bar 30 is provided with screw thread 321 near the periphery of second end 32, screw thread 321 combines with screw thread 51 and the hold-doun nut 60 of adjusting nut 50, adjust between nut 50 and the screwed pipe 20 and be provided with liner 52, packing ring 52 can play buffering and the effect that reduces noise in test is carried out.The outside surface of reference test bar 30 is provided with scale 34, and position the best of scale 34 is between the bulge loop 33 and first end 31.
Please refer to the assembled sectional view of Fig. 2 A test head of press key tester preferred embodiment of the present invention.Spring 25 is placed in the through hole 22 of screwed pipe 20, and the upper end stays on head bearing 23, the bulge loop 33 of lower end pushing and pressing reference test bar 30, and when spring 25 was upheld fully, bulge loop 33 relied on lower bearing 24, made reference test bar 30 can not break away from screwed pipe 20.Test head of press key tester of the present invention utilizes joint portion 11 to be installed in the movement arm (not illustrating) of a key testing machine, and fixed screw 16 is screwed into fixed orifice 15 and packing movement arm, makes holder 10 firm being combined on the movement arm.
Please refer to Fig. 2 B, Fig. 2 B is the action synoptic diagram of Fig. 2 A.Test is the below that electronic goods to be measured is placed test machine when carrying out, with the test head of press key tester adjustment in alignment with directly over the electronic goods button to be measured, start after the test machine, movement arm drives whole test head of press key tester and pumps, and makes quality and the life-span of briquetting 40 continuous repeated presses buttons 70 with the test button.The contact that repeats when briquetting 40 and push button 70 when testing, briquetting 40 pushing tow reference test bars 30 upwards, and by bulge loop 33 compression springs 25, by the response force that compression spring 25 is accumulated, the strength size of its pressing keys also is same as the response force of spring 25; Drive whole test head of press key tester and move up when movement arm moves up, briquetting 40 is left button 70, and reference test bar 30 moves down by spring 25 restoring force pushing tows,
The pressing force that please refer to Fig. 3 test head of press key tester preferred embodiment of the present invention is adjusted synoptic diagram.Different electronic goods checks have different pressing force requirements, when desire is adjusted pressing force, unclamp hold-doun nut 60 earlier adjustment nut 50 can be rotated with respect to reference test bar 30, and make adjustment nut 50 produce axial displacement at reference test bar 30 by the relative motion of screw thread 51 and screw thread 321.Because scale 34 is to portray on reference test bar 30 outside surfaces by prior accurate correction, therefore, when rotation adjustment nut 50 makes reference test bar 30 up mobile, bulge loop 33 is with compression spring 25, and then the pressing force of increase reference test bar 30, can inspect corresponding scale 34 readings by the lower surface 26 of screwed pipe 20 simultaneously, can show adjusted pressing force, and need not measure with other pressure measuring instrument.
After the pressing force adjustment was finished, nut 50 was adjusted in 60 packings of rotation hold-doun nut, made to adjust not reference test bar 30 generation displacements relatively again of nut 50.
Please refer to the height control synoptic diagram of Fig. 4 test head of press key tester preferred embodiment of the present invention.Because different electronic products has different button height, or the different key of identical product also may have differing heights, when desire is adjusted test head of press key tester of the present invention compared to the height of button to be measured, loosen fixed screw 14 earlier, then rotating screwed pipe 20 makes screwed pipe 20 with respect to holder 10 up or move down, because reference test bar 30 all moves with screwed pipe 20 with spring 25 assemblies such as grade, therefore the pressing force of adjusting can not change; Again fixed screw 14 is tightened compressing screwed pipe 20 after to be adjusted the finishing, screwed pipe 20 can not moved with respect to holder 10 again.
Test head of press key tester of the present invention utilizes the joint portion 11 of holder 10 to be combined in one to have on the test machine of power, drives measuring head by test machine and pumps, and the button of pushing electronic product to be tested carries out the test of life-span or quality.When needs are tested a plurality of button simultaneously, can simultaneously a plurality of test head of press key tester of the present invention be fixed on the test machine, adjust different height at individual other button, can also adjust the size of pressing force, and directly by the adjusted pressure value of scale 34 interpretations, in the process of carrying out different product tests, it is the time that can shorten adjustment in a large number.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
