Abstract
A circuit-board testing tool comprises a lower press plate. The lower press plate is equipped with a plurality of the first supporting poles and at least one second supporting pole. A first elastic piece and a second elastic piece are respectively covered on the outside of the first supporting pole and the second supporting pole. At least one side of the lower press plate is equipped with a fixing part, and the fixing part fixes the first fixing part with the limiting part on the same side of the lower press plate via the fixing piece. A bearing plate is positioned on the first supporting pole and supported by the first elastic piece, and the bearing plate is equipped with a plurality of fixing poles. An upper press plate is positioned on the second supporting pole and supported by the second elastic piece. The part of the upper press plate which corresponds to the same side of the first clamping part fixedly positioned on the lower press plate is equipped with a second clamping part, and the hook part of the first clamping part faces to the hook part of the second clamping part. Therefore, the distance between the lower press plate and the upper press plate for clamping the circuit board to be detected can be adjusted via adjustment of the location of the first clamping part when the thickness of the circuit board to be detected changes.
Description
Technical field
A kind of testing tool, particularly a kind of testing tool in order to testing circuit board.
Background technology
See also Fig. 1 a, it is in order to show the synoptic diagram of available circuit board test tool construction.As shown in the figure, existing testing tool for circuit board 1, it comprises lower platen 11, this lower platen 11 is provided with four first support columns 111 and two second support columns 112, this first support column 111 is arranged with first elastomeric element 113 and second elastomeric element 114 respectively with these second support column, 112 outsides, the side 11a of this lower platen 11 offers fixed part 115, and this fixed part 115 is fixed in first hook part 117 by fixture 116 this side 11a of this lower platen 11; Loading plate 12, it is set up on this first support column 111, and this loading plate 12 is provided with four fixed legs 121 and three pushbutton switches 122; Top board 13, it is arranged on this second support column 112, this top board 13 is provided with second hook part 131 corresponding to the side 11a that this lower platen 11 is fixed with this first hook part 117, and the end 117a that colludes of this first hook part 117 holds 131a relative with colluding of this second hook part 131.
See also Fig. 1 b, it shows the synoptic diagram of existing testing tool for circuit board when folder is established circuit board to be tested.As shown in the figure, when circuit board 14 to be tested places on the aforementioned existing testing tool for circuit board 1, this top board 13 can be depressed towards these lower platen 11 directions, and the colluding of end 117a and this second hook part 131 of colluding of this first hook part 117 held the mutual trip of 131a, by the reacting force that is produced behind this first elastomeric element 113 and second elastomeric element, 114 pressurizeds, hold the end 131a that colludes of 117a and this second hook part 131 to draw in the opposite direction the colluding of this first hook part 117 of mutual trip, thereby the pressure by this top board 13 should be fixed on this loading plate 12 by circuit board 14 to be tested.
