Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As depicted in figs. 1 and 2, the ageing test jack of tape insulation frame encapsulation components and parts, comprise the lid 10 and the base 4 that arrange respectively up and down, described base 4 Shang Si limits are axially symmetrically arranged with 80 long and narrow cavitys 17 that bottom has through hole, in described long and narrow cavity 17, be provided with resilient contact 1, 2, 3, resilient contact 1, 2, 3 adopt " bow " type structure, " Gong”Xing upper surface is for contacting with tested device wire, the end of " bow " type passed the through hole on long and narrow cavity 17 and the outside that stretches out in base 4 for connection line plate, on described base 4, be provided with 3 alignment pins 7 corresponding with position, tested device technology hole.
In described base 4, be provided with the locating piece 5 that can move up and down, between described locating piece 5 and base 4, be provided with Compress Spring 6, on the Si Ge angle of described locating piece 5, be provided with 4 boss and form a square container cavity, on described locating piece 5, be provided with and resilient contact 1,2,3 upper ends location notch one to one, on described locating piece 5, be provided with the positioning boss 16 with tested device wire matched in clearance.
In described lid 10 centre position, be provided with the movable holddown 11 of pin joint, stressed even to guarantee in compressing tested device process, in described lid 10 one end, be provided with " fourth " type hook 15 as the locking device of socket, after socket closure, work the effect of being connected and fixed.
Most important parts as ageing test jack; the design of resilient contact 1,2,3 is the most key; resilient contact 1,2,3 in the present embodiment is " bow " type structure; by adjusting the overarm of " bow " type and inclination angle to obtain suitable clamping force; and reduce resilient contact 1,2,3 elastic force under the prerequisite that guarantees good contact resistance as far as possible; thereby the lead-in wire that makes tested device is not crushed, coating is not destroyed, and colleague has also protected the coating of resilient contact 1,2,3 and extended the useful life of ageing test jack itself.Because the lead-in wire pitch of this ageing test jack is only 0.5mm, for the ease of wiring and the making of wiring board, before contact 1,2,3 ends adopt in after the form that is dislocatedly distributed of three rows.
The present embodiment when mounted, first resilient contact 1,2,3 is pressed in the structure inserted base 4 corresponding with tested device lead-out wire, again Compress Spring 6 is put into the middle circular hole of base 4, then by careful the packing in base 4 of locating piece 5, guarantee that all resilient contacts 1,2,3 are in the location notch of locating piece 5, again 3 alignment pins 7 are knocked in the installing hole of base 4 correspondences, completed portion's dress of base 4.Briquetting 11 is packed in lid 10 and with axle 12 pin joints, Compress Spring 13 is being put into the installing hole on lid 10, then pack hook 15 into and use axle 14 pin joints, complete portion's dress of lid 10.The base 4 finally portion being installed and lid 10 are reinstated axle 8 pin joints together with torsion spring 9 one.
Hook 15 in the present embodiment is retaining mechanism, when socket is during in non operating state, at elastic reaction lower cover 10 and the base 4 of torsion spring 9, is the angle that is greater than 90 ° in open configuration.During work, tested device is put into the square container cavity on the locating piece 5 of base 4, then by make lid 10 upset by pressure hook 15 until with base 4 engagements, then in the effect of Compress Spring 13, be issued to the object of locking, after having tested, by making lid 10 separated with base 4 by the inner side of pressure hook 15, and open under the elastic reaction of torsion spring 9, then take out tested device, carry out next round test or ageing work.
This flip structure adds that the design of resilient contact becomes jack design the structure of ZIF, avoided the damage to the coating of tested device, lead format in plug process, simultaneously also can avoid socket wearing and tearing in use itself, thus the technological difficulties that large, the resistance to environment of contact resistance is weak, consistency is poor, useful life is short while thoroughly having solved again high temperature aging and performance test.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of making, within all dropping on protection range of the present utility model.
