Embodiment Construction

[0021] figure 1 The contact device 1 is shown enlarged and only schematically. The contact device 1 has four guide elements 2 , 3 , 4 and 5 arranged parallel to each other and spaced apart in the axial direction a, and spacer elements 6 , 7 and 8 arranged between the guide elements. Individually, spacer element 6 is positioned between guide elements 2 and 3 , spacer element 7 is positioned between guide elements 3 and 4 , and spacer element 8 is positioned between guide elements 4 and 5 . The guide elements 2, 3, 4 and 5 are in the form of guide plates 9, 10, 11 and 12, and the spacer elements 6, 7 and 8 are in the form of frames, thereby forming open spaces 13, 14 and 15 inside the contact device. The non-conductive guide plates 9 to 12 each have a number of notches 16, 17, 18 and 19, wherein the notches 16, 18 and 19 are axially aligned with each other and the notches 17 are offset from the alignment in the radial direction r. The contact element 20 is arranged axially dis...

Abstract

The device (1) has guiding elements (2-5) comprising corresponding openings (16-19) e.g. bores, through which contact elements (20) e.g. contact needles, axially run. The contact elements project at a side of the related guiding element (5) allocated to an electrical device under test (25) for contacting the device under test. An adjusting device (28) e.g. pneumatic-, hydraulic- and / or piezo-adjuster, adjusts an axial distance of the guiding elements or an axial length of the guiding element (5) allocated to the device under test for adjusting a projection length (H) of the contact elements. An independent claim is also included for a method for contacting an electrical device under test.

Description

technical field [0001] The invention relates to a contact device for contacting an electronic test element to be tested, in particular a test element provided with tin-plated contacts, with at least two guide elements having a notch through which the said The contact element extends essentially axially, said contact element protruding from the face on which the assigned guide element moves towards said test piece to contact said test piece. Background technique [0002] Contact devices of the kind mentioned at the outset are known. In order to position and hold the strip-shaped contact element, it is placed in recesses in guide elements arranged axially spaced apart from one another. The guide element is made in the form of a guide plate. The notches are preferably made in the form of holes, wherein the guide length and the position of the holes are fixed parameters. The strip-shaped contact becomes a needle, one end of which contacts the detection point of the detection ...
