DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0064] In the description given below of preferred embodiments of the present invention, the same reference signs denote the same or comparable components.

[0065] The figures show various views of a mechanism 1 for securing a connector device in the form of a receiver and a mating connector device in the form of an interchangeable test adapter to one another and releasing them from one another. FIGS. 1 and 2 show the receiver frame 2, into which a plurality of modules with connectors may be releasably inserted. FIGS. 2 and 3 show the frame 3 of the interchangeable test adapter, into which may be inserted a plurality of modules with mating connectors which correspond to the connectors of the receiver. The interchangeable test adapter may be drawn in the plug-in direction towards the receiver and secured thereto using catches 4, which are arranged on the receiver. As a result of this drawing effect, contact may be established between the previously disconnected connectors and corresponding mating connectors.

[0066] To this end, the catches 4 may be moved from an open position, in which the interchangeable test adapter may be released from the receiver, into a locking position, in which the interchangeable test adapter is secured to the receiver, and also back from the locking position into the open position, wherein the catches 4 in each case perform a combined pivoting and translational movement. In FIGS. 1, 2, 4 to 8, 14 and 16 the catches 4 are depicted in their locking position and in FIGS. 9, 10, 13 and 15 in their open position. It is clear therefrom that the pivoting movement of each catch 4 proceeds about a pivot axis which extends substantially perpendicular to the plug-in direction.

[0067] As is clear from FIGS. 1 to 3, both the receiver frame 2 and the frame 3 of the interchangeable test adapter have longer upper 5 and lower 6 edges and shorter side edges. Four pairs of catches 4 are arranged respectively on the upper 5 and lower 6 edges, wherein the claws 7, described in greater detail below, as a rule point in each case towards the opposing edge 5, 6. In an alternative embodiment of the invention, which is not shown, a further row of catches 4, preferably pairs of catches, e.g. 4 pairs of catches, is arranged, preferably around half way, between the upper 5 and lower 6 edges, wherein in each pair of catches one claw 7 preferably points towards the upper edge 5 and another towards the lower edge 6.

[0068] Each row of catches 4 is driven by a shaft which is not shown in the figures, and therefore in FIGS. 1 and 2 one shaft is located in the upper receiver edge 5 and a further shaft in the lower receiver edge 6. By means of a gear unit, these two shafts are jointly driven by an electric motor, which is likewise not shown in the figures, in order to move them from the open position into the locking position and vice versa. In this respect, rotation of the shaft by a quarter of a full revolution moves the catches 4 from the open position into the locking position or vice versa. At holes 8 depicted in FIGS. 1 and 2 in the upper edge of the receiver frame, switches which are not depicted in the figures are arranged for operating the electric motor so that it moves the catches 4 between the open position and the locking position.

[0069] Each catch has one claw 7, with which it may engage a mating catch 9 on the frame of the interchangeable test adapter. The mating catch 9 takes the form of a web, which is formed by a through-hole 10 at the edge of the frame 3 of the interchangeable test adapter. The claw has two fingers 11, one finger 11 of which engages in the through-hole 10, such that the claw 7 may receive the mating catch in a recess 12 between the fingers 11. The recess 12 extends perpendicular to the plug-in direction.

[0070] As is clear from FIGS. 10, 13 and 14, the drive of the catch 4 has a crank drive, for converting the rotation of the shaft into movement of the catch between the open position and the locking position. To this end, the crank drive comprises a bush 13, which is arranged non-rotatably on the shaft, not shown, as a result of having a hexagonal through-hole which corresponds with a hexagonal shaft cross-section. As an alternative to the hexagonal shape, if the shaft is suitably shaped, then a tooth-shaped hole, spline shaft hole or square hole or a hole with a groove for a feather key are also for example feasible for mounting the bush non-rotatably on the shaft.

[0071] A crank arm 14, to which a connecting rod 15 is coupled with a pin, is arranged on the bush 13. The connecting rod 15 drives two catches 4 located on opposing sides of the crank drive, due to being coupled thereto by means of a connecting rod shaft 16 on the catch side. In this way, each of the pairs of catches is driven by a common crank drive.

[0072] Each catch 4 has a first slotted link, which consists of a first elongate hole arranged in curved manner in the catch and acting as first link guide and a journal 18 formed by the bush and acting as first link block. The curvature of the first elongate hole is located in the region of the open position of the catch. A second slotted link is, moreover, provided, the second link guide thereof being formed by second elongate holes 19 in metal sheets which are located in each case at the sides of the catches 4 remote from the crank drive. The metal sheets 20 additionally each have a bearing bore 21, in which the journals 18 formed by the bush 13 rotate. The second link blocks of the second slotted links are formed by extensions of the connecting rod shaft 16 on the catch side, with which the connecting rod 15 is coupled to the catches 4.

[0073] The curvature of the first link guide, together with the linear profile of the second link guide, brings about a pivoting movement of the catches 4 in the vicinity of the open position thereof about an axis running through the second link block. In another embodiment of the invention which is not shown, the second link guide has a curvature at its open position end which is a mirror image of the curvature of the first link guide. Then the catch 4 does not perform a pivoting movement, but rather a translational movement.

[0074] As is clear for example from a comparison of FIGS. 13 and 14, each catch 4 forms a toggle lever, wherein the first lever arm is formed by the section from the claw to the first link block and the second lever arm by the section from the first link block to the second link block. During travel from the open position to the locking position, the position of the first link block relative to the catch shifts such that the ratio between the first and second lever arms diminishes.

[0075] The invention enables an advantageously compact and simple design, which is capable of drawing the mating connector device reliably in and securing it. The large number of catches allows the forces to be uniformly distributed during locking, such that the mating connector device and indeed the mechanism according to the invention may be of less solid and therefore of lighter construction. The mechanism according to the invention is moreover simple to assemble; for instance, the locking unit consisting of pair of catches 4, crank drive and slotted links may be simply pushed onto the shaft and simply positioned at the required point depending on the embodiment of the connector device. Replacement in case of repair is also correspondingly simple.

[0076] The features disclosed in the above description, the claims and the drawings may be of significance for implementation of the invention in its various embodiments either individually or in any desired combination.
