An XYX cross-connect switching matrix (200) is provided for use in telecommunications apparatus. The matrix (200) comprises first (10), second (20) and third (30) arrays of parallel conductor tracks (11-14, 21-28, 15-18). The parallel conductor tracks (21-28) of the second array (20) are oriented perpendicular to the conductor tracks (11-14) of the first array (10) and to the conductor tracks (15-18) of the third array (30). The first (10), second (20) and third arrays (30) each lie in planes parallel to and spaced from one another, with the second array (20) being located between the first (10) and third (30) arrays. A first set of electrical contact sleds (41) is provided between the first (10) and second (20) arrays, whilst a second set of electrical contact sleds (42) is provided between the second (20) and third (30) arrays. These sleds (41,42) enable any X conductor track (11-18) in the first (10) or third (30) array to be electrically connected to any Y conductor track (21-28) in the second array (20).
A cross-connect switching matrix for use in telecommunications apparatus, comprising:
A cross-connect switching matrix as claimed in any of the preceding claims, wherein the electrical contact sleds are adapted to be driven in a direction parallel to the conductor tracks in an adjacent array.
A cross-connect switching matrix as claimed in any of the preceding claims, wherein the first set of electrical contact sleds are adapted to be driven in a direction parallel to the conductor tracks in the first array, and the second set of electrical contact sleds are adapted to be driven in a direction parallel to the conductor tracks in the third array.
A cross-connect switching matrix as claimed in any of the preceding claims wherein the conductor tracks of the second array are simultaneously presented on both upper and lower faces of the array.
A cross-connect switching matrix as claimed in any of the preceding claims, wherein the contact sleds are adapted to connect multiple conductor tracks on the first and/or third arrays with multiple conductor tracks on the second array.
A cross-connect switching matrix as claimed in any of the preceding claims, further comprising drive means adapted to drive the contact sleds.
A cross-connect switching matrix as claimed in any of the preceding claims, wherein the arrays are printed circuit boards.
