Definitions

  • the invention relates to a device for the simultaneous production or release of a plurality of plug contact connections, each consisting of plug pins and plug terminals arranged in a matrix, the one matrix, e.g. B. a module with the connector pins for making contact or solution parallel to the other matrix, z. B. a circuit board with the plug terminals is slidably mounted.
  • connection to the printed circuit is produced by plug pins which penetrate the substrate and are conductively connected to the electrical lines on one side of the substrate and protrude perpendicularly to the plane of the substrate on its opposite side.
  • plug pins which penetrate the substrate and are conductively connected to the electrical lines on one side of the substrate and protrude perpendicularly to the plane of the substrate on its opposite side.
  • a connector connection described in DE-A-2 332 556 has become known, in which the individual connector terminals consist of a U-shaped, resilient yoke with spring arms formed thereon, on which contact pieces of cylinder sector or barrel shape are attached.
  • the contact pieces have beveled contact surfaces on their edges, which facilitate the entry of the plug pin into the space between these surfaces.
  • the shaft of these plug terminals is designed so that they have a certain elastic mobility.
  • the insertion force in the known plug connection is zero. This is achieved by first inserting the connector pins into an area adjacent to the contact pieces of the connector terminal and then inserting the pins between the opposite contact surfaces, parallel to the planes of the matrix of the plate and the module.
  • the shape of the surfaces of the contact pieces and the resilient flexibility of the plug terminals on the other hand, only require low insertion forces when the contact pins are inserted lengthwise between the contact surfaces, the opposite cylindrical or barrel-shaped surfaces performing the same function during insertion of the connector pins as before the beveled flanks of the contact pieces.
  • the opposite contact surfaces establish a clear contact between each terminal and the associated pin. This applies in particular if individual connector pins or connector terminals are not properly aligned or are even bent.
  • a cam drive device for the parallel displacement of the module relative to the circuit board, which, depending on a rotation about a predetermined axis of rotation in a direction between a first and a second angular position, has a linear relative movement between them connecting arrangements up to the engagement of the connector pins, and between the second and a third angular position in the same direction causes a second linear relative movement of the arrangements to be connected in the opposite direction.
  • the invention has for its object to provide a device of the type mentioned above, which has a much simpler structure and can also be produced at a correspondingly lower cost, but is nevertheless able to provide modules with highly integrated circuits and a correspondingly large number in high density arranged Insert or release neter connector pins with reliable contact and damage-free into the associated connector terminal matrix, without canting or torsional forces acting on the module.
  • the particular advantages of the device according to the invention lie in the simple, inexpensive manufacture and ease of use. Another advantage is that the device according to the invention can be used for connector pin arrangements, such as modules, of different heights without the need for adaptation.
  • FIG. A connector is shown, which is particularly suitable for the device according to the invention.
  • This consists of a plug terminal 10 with a U-shaped yoke 11 and a pair of spring arms 12 and 13, which, following the legs of the yoke 11, extend vertically in the longitudinal direction.
  • a shaft 14 projects downward from the central region of the yoke 11.
  • the upper ends of the spring arms 12 and 13 are designed such that they each form a cylindrical-section or barrel-shaped contact piece 15 for producing a reliable contact connection with the plug pin 16.
  • correspondingly designed contact pieces can alternatively also be preformed and on the spring arms 12, 13, z. B. by soldering.
  • the distance between the spring arms 12 and 13 is dimensioned somewhat smaller than the diameter of the plug pin 16.
  • the plug pin 16 is shown as a cylindrical pin, but can also have other shapes, z. B. be designed as a flat pin.
  • a special feature of the connector terminal 10 are their different spring constants. For example, it has a spring constant for alignment in the direction of the straight double arrow on the shaft 14, which is approximately one sixth of the spring constant of each of the spring arms 12, 13. It also has a very low spring constant at its seat in the direction of the curved double arrow, which, for. B. is a twentieth of the spring constant of each of the spring arms 12, 13 and is therefore essentially negligible.
  • the low spring constant, in particular in the alignment direction of the shaft 14, makes it possible for it to yield somewhat, depending on forces caused by poor alignment of individual plug pins 16, when these are inserted either laterally or lengthwise into the space between the two opposing contact pieces 15 .
  • This flexibility of the shaft 14 thus ensures that the opposing, cylindrical or barrel-shaped contact pieces 15 make a reliable contact connection with the plug pin 16.
  • the resilience of the shaft 14 and the identical spring constants of the two contact pieces 15 cause the plug terminal 10 to be resilient in the direction of alignment, thereby eliminating some of the cumulative tolerances.
  • the connector terminals 10 are of high density, namely at intervals of approximately 1.25 mm from the center of the connector to the connector can arrange in the middle.
  • a preferred area of application for such plug connections is their use on printed circuit boards.
  • the shaft 14 of the plug terminal 10 is in holes 17 of the board 18 of a printed circuit board, e.g. B. by soldering, attached and electrically connected to corresponding circuit patterns and / or internal signal levels and / or a neutral level of the plate.
  • the plug pins 16 form the other half of the plug connection and serve, for example, as input / output pins of a component of an integrated circuit, a module or the like, which is electrically connected to the board.
  • the device shown there for inserting and removing modules contains a frame 19 which is attached to a plate 18 of a printed circuit, e.g. B. is glued or soldered to this.
  • the plate 18 contains a stiffening frame, and the frame 19 is in turn provided with a cutout 21 for receiving a matrix 22 of plug terminals 10, in the manner as previously described with reference to FIG. 5.
  • the spring housing 24 contains a plate 26 with a matrix 27 of openings 28 which are aligned with the connector terminals 10 protruding from the plate 18 of the printed circuit.
  • FIG. 6 shows such an opening 28.
  • each of the openings 28 consists of a part 29 for receiving the spring arms 12 and 13 and the contact pieces 15 of the associated plug terminal 10 and also a further part 30 for the plug pin 16 of the module.
  • pairs of guide grooves 32, 33 are provided for receiving and guiding a module 34, and between these guide grooves there is a groove 35 for receiving the ends of an actuating rocker 36.
  • the latch 26 is U-shaped, and two locking arms 37 of the actuating rocker 36 each have a locking part 38 at their ends. In parallel to each of the locking arms 37, a retaining lug 39 is provided, the purpose of which will be described later.
  • the actuating rocker 36 is U-shaped with arms 40 on both sides, each of the arms 40 being L-shaped. Pins 41 are attached to the outside of the free ends of the arms, while one pin 42 is attached to the inside. A handle 43 is located on the upper part of the actuating rocker 36.
  • the actuating rocker 36 is rotatably mounted on the spring housing 24 by means of the pins 41 projecting into bores 44 in the sides 31, the free ends of the arms 40 and the pins 42 being guided in the grooves 35 are.
  • the pivot bearing of the actuating rocker 36 is arranged essentially in the center of the module 34 and the spring housing 24, whereby any manufacturing tolerances are shared.
  • a cooling plate 45 with a plurality of cooling pins 46 is arranged on the upper surface of the module 34.
  • the connector pins 16 protrude from the opposite base plate of the module 34 in a matrix-like arrangement. 3 and 4, two guide pins 47 are provided on the base plate of the module 34, which facilitate the precise insertion of the module.
  • a plate 50 is further attached, on which guide lugs 51, 52 and actuating lugs 53, 54 are located.
  • Fig. 3 the device described is shown before inserting a module.
  • the actuating rocker 36 is shown here in its counterclockwise pivoted position, in which the arms 40 rest on outwardly inclined surfaces of the locking parts 38 on the locking arms 37 of the locking bar 25.
  • the module 34 is inserted through the opening in the actuating rocker 36, the guide lugs 51, 52 and the actuating lugs 53, 54 on the module 34 being inserted into the guide grooves 32, 33 and into the groove 35 in the sides 31 of the spring housing 24.
  • Grooves 55 between the actuating shoulders 53, 54 on the two opposite lateral edges of the module 34 accommodate the pins 42 on the arms 40 of the actuating rocker 36 (cf. FIGS. 3, 4).
  • the lugs 51 to 54 and the associated grooves 32, 33 are designed so that the module 34 can only be used in the orientation shown and inadvertent insertion of the module is prevented in an orientation rotated by 180 °.
  • the pair of guide pins 47 of the module 34 arrives in directional grooves 56 in the plate 26. This results in a fine alignment of the module 34 with respect to the frame 19 after the previous rough alignment, so that the connector pins 16 are now exactly aligned with the openings in the plate.
  • the actuating rocker 36 enables a visual check as to whether the module 34 is inserted correctly. It can be moved freely from its starting position (Fig. 3) on the locking parts 38 of the bolt 25 and the beveled surface of the grooves 35 into their actuated position, the pins 42 reaching the wider area of the groove 55 (Fig. 4).
  • the angled ends of the guide lugs 51, 52 are in such a position that they lie under the corresponding edges in the spring housing 24 slide, which prevents the module. 34 can move upwards (cf. FIGS. 3, 4).
  • the plug pins 16 are arranged adjacent to the contact pieces 15 of the spring arms 12, 13, as shown in FIGS. 6 and 7.
  • the vertical position of the plug pins 16 is determined here by a stop 57 (FIG. 1) at every angle of the plate 26.
  • the handle 43 with the actuating rocker 36 is pivoted clockwise around its pins 41 according to FIGS. 3 and 4.
  • the pins 42 on the arms 40 of the actuating rocker 36 are adjusted to the left and come into engagement with the actuating projections 54 on the module 34, as a result of which the latter is pushed to the left.
  • the locking arms 37 are resilient in the direction transverse to this adjustment movement of the actuating rocker 36, so that when the actuating rocker 36 is actuated in the manner described, the arms 40 act on the outer surfaces of the locking parts 38 and move them inward. As soon as the arms 40 have reached beyond the locking parts 38, the locking arms 37 snap outwards again and lock the arms 40 of the actuating rocker 36. This ensures that the modules 34 have reached their position correctly and the plug pins 16 are in contact with the contact pieces the spring arms 12, 13 are.
  • the latch 25 contains a stop surface 58 which limits the actuation of the actuating rocker 36, which prevents excessive actuation of the rocker 36 and possible breakage of the plug terminals or contact springs.
  • the module 34 moves back with the plug pins 16 until the spring arms 12, 13 and the plug pins 16 are in a balanced position and thereby reach the position according to FIG. 9 to have.
  • the arms 46 of the actuating rocker 36 are each provided with a groove 59, the angle of which corresponds to the angle 60 on the rear flank of the locking parts 38, so that the arms 40 now released move back and rest against the angular surface of the locking part 38.
  • the amount of this movement corresponds to the path which the plug pins 16 initially traveled in the manner described above beyond the end position.
  • the arms 40 are now locked by means of the locking parts 38, as a result of which the module 34 is fixed in its prescribed position.
  • the locking arms 37 for unlocking the actuating rocker 36 are pressed in the direction of one another and at the same time the actuating rocker 36 is pivoted counterclockwise.
  • the pins 42 cooperate with the actuating projections 53, as a result of which the module 34 reaches its position shown in FIG. 3, in which the contacts are separated from one another.
  • the actuating rocker 36 is pivoted counterclockwise until the arms 40 rest against the angled surface 61 of the groove 35 (FIG. 3).
  • the guide lugs 51, 52 detach from the spring housing 24, and the module 34 can now be removed from the device.
  • the retaining lugs 39 limit the aforementioned inward bending of the locking arms 37 in order to prevent them from being overstressed or breaking.
