In the printed circuit board test process, how to make things convenient for, reliably with any electrical node on the printed circuit board, draw or inject pumping signal such as the test signal of the via hole of components and parts pad, electrical traces or device pin etc., be puzzlement electrical design and commissioning staff's a problem always.
A kind of solution is to adopt test test pencil or miniature test clip, and the signal of related electric node is drawn.But this solution requires the commissioning staff in test process, keeps the close contact of test test pencil or miniature test clip and tested electrical node with hand, otherwise, will affect test result, also bring inconvenience to debugging work.Simultaneously, because printed circuit board is to high density, large capacity future development, the distance of adjacent electrical node is more and more less, and this method of testing is easy to form electric short circuit.
Another kind of solution is to adopt test probe to make up a kind of equipment of test probe bed, and perhaps by computer control, actuator guiding test probe is drawn the signal of tested electrical node automatically.This solution can well solve the reliable contact problems of electrical node, brings convenience to the commissioning staff, makes up test probe bed complexity but also exist, and is confined to the printed circuit board of single variety is tested; The computer-controlled instrumentation cost is high, is difficult to the shortcoming of popularization and application.And work as tested printed circuit board owing to testing requirement, in the time of can't separating separately test with other parts, above-mentioned solution is just helpless.
Summary of the invention
The purpose of this utility model is: proposing a kind of can the positive and negative two sides of tested printed circuit board be the test plane, make test probe to the detecting electric node can be fast, accurate location, the printed circuit board test probe movable bracket that electric signal is reliably drawn and imported.
Technical solution of the present utility model is: movable bracket comprises symmetrical two supporting plates, two slide plates, slide block, slide bar, two supporting plate symmetries are installed on the platform, the both sides of supporting plate are provided with mounting hole, two slide plates link to each other with supporting plate by the mounting hole on the supporting plate, jointly consist of tested printed circuit board support frame; On the every slide plate slide block is set, slide block is along the left and right movement of slide plate; Slide bar is arranged on the slide block, and slide bar moves up and down; The slide bar top is provided with the test probe jackscrew.
The both sides of described supporting plate are provided with row's mounting hole, and two slide plates link to each other with supporting plate by the arbitrary mounting hole on the supporting plate, make slide plate place the diverse location of supporting plate.
Described slide plate is the slide plate in rectangle or other non-circular shape cross section.
Described slide bar is round section, and slide bar rotates in slide block vertically.
The advantage that the utlity model has and beneficial effect, the utility model adopt side plate and slide plate to make up the mode of printed circuit board outside framework, guarantee take the positive and negative two sides of tested printed circuit board to be to test the plane; Can change the slide plate of upper and lower installation site, guarantee that investigative range can contain whole printed circuit board plate face; Slide block that can left and right movement can upper and lower fine setting and the slide bar of rotation, has guaranteed the accurate location of arbitrary electric measuring point in the test plane; The test probe jackscrew at slide bar top can be controlled stretching out, drawing back of test probe, has guaranteed reliable introducing and the derivation of electric signal, the processing of this device is simple, and accurate positioning is easy to install, easily go fast, and can guarantee the reliable contact of electric signal in the test process.
This device can satisfy the test of the different printed circuit boards of same size; Size by change left and right side supporting plate and slide plate can also satisfy the test of different size printed circuit board.

Embodiment
Movable bracket comprises symmetrical two supporting plates 1 among Fig. 1, two slide plates 2, slide block 3, slide bar 4, two supporting plate 1 symmetries are installed on the platform, the both sides of supporting plate are provided with mounting hole, two slide plates 2 link to each other with supporting plate by the mounting hole on the supporting plate, jointly consist of tested printed circuit board support frame; 2 arrange slide block 3 on the every slide plate, and slide block 3 is along the left and right movement of slide plate; Slide bar 4 is arranged on the slide block 3, and slide bar 4 moves up and down; The slide bar top is provided with the test probe jackscrew.Its design concept is as follows: printed circuit board left and right side supporting plate 1 passes through forward and backward slide plate 2, and with mounting platform 7, jointly consists of tested printed circuit board support frame.When a left side, tested printed circuit board 8 edge, after chute on the right side supporting plate 1 inserts printed circuit board bus hub 6, formation with tested printed circuit board before, test plane centered by the rear plate face, slide plate itself can also be along a left side, on the right side supporting plate 1, lower change installation site (Y-direction), purpose is the investigative range that makes test probe, can contain whole printed circuit board plate face, before, some slide blocks 3 are set on the tail skid 2, slide block 3 can be along slide plate 2 left sides, (directions X) moves right, slide bar 4 is arranged on the slide block 3, the top fixing test probe 5 of slide bar 4, slide bar 4 can more than, lower movement (Y-direction fine setting), the test probe 5 that slide bar 4 tops are fixing, test probe 5 can stretch out, draw back (Z direction), slide bar 4 except can more than, outside the lower movement, can also be along the axial rotation of slide bar 4, make the test probe 5 can vergence direction, namely be not orthogonal to the direction of printed circuit board plate face, survey the electrical node on the printed circuit board plate face.When the 5 common cooperation of two test probes, can survey more closely spaced adjacent two electrical nodes.Left and right when mobile along slide plate 2 for guaranteeing slide block 3, can around slide plate 2 axial rotation, not be specifically designed to the slide plate 2 in rectangle or other non-circular shape cross section.
The principle of work of this device is as follows:
After tested printed circuit board inserted the printed circuit board bus hub along the chute on the left and right side supporting plate, the slide plate that install on the two sides before and after on the upper and lower adjustment left and right side supporting plate, need the point tested on the relatively tested printed circuit board, at a suitable height and position.Then, adjust the left and right position of slide plate top shoe, the last upper and lower position of carefully adjusting the slide block upper slide bar, the point that these needs of test probe accurate contraposition are tested.Carefully adjust the length that the test probe on the slide bar stretches out, make test probe and the some close contact that needs test.Connect the electrical cable of this test probe, enter test procedure.
When needs are tested new electrical node, repeat above-mentioned adjustment process.
Fig. 2 represents: the situation when " printed circuit board test probe movable bracket " device uses: tested printed circuit board 8 inserts the support frame that is made of left and right side supporting plate 1 and upper and lower slide plate 2 along the chute on the left and right side supporting plate 1.Because the spacing of the integrated circuit (IC) chip pin on the tested printed circuit board 8 is less, the slide bar 4 on two slide blocks 3 on the upper slide drives two adjacent chip pins of the oblique contact of test probe respectively around self axial-rotation.Slide bar 4 on the slide block 3 on the lower skateboard drives the vertical tested printed circuit board 8 of test probe, the electrical node that contact is relevant.
