Definitions

  • the invention relates to a screw terminal for the electrical connection of cables or wires equipped in particular with eyelet-shaped cable lugs, with a housing and a clamping screw which passes through a first clamping plate in the screwing-in direction and a second clamping plate when the clamp is closed, and into a bore when the clamp is open the first clamping plate remains immersed and clears the space between the first and the second clamping plate, the second clamping plate having a bore with a screw thread and the shaft of the clamping screw in an area adjacent to the screw head, the axial length of which is at least the axial length of the engagement of the first Clamping plate in screw threads corresponds to the clamping screw, is reduced to a small diameter.
  • Screw terminals of this type are used, for example, as connecting terminals for switches, electrical devices, such as motors, or also sockets.
  • a clamp has become known from US Pat. No. 4,611,876.
  • the second clamping plate is arranged stationary in the housing, while the first clamping plate is displaceable in the axial direction.
  • the clamping screw is guided in a cage connected to the first clamping plate. This cage is non-rotatable and axially displaceable in the housing with play.
  • this cage with the first clamping plate either falls on the second clamping plate or moves away from it.
  • the free distance between the first and the second clamping plate is therefore not guaranteed when the clamp is open, so that the insertion of the cable or the Cable lug between the first and the second clamping plate is difficult when the clamp is open. This applies in particular if the screw terminal is difficult to access or if it is installed overhead.
  • the formation of the first clamping plate with a cage holding the clamping screw is complex.
  • the first clamping plate is designed to be axially immovable and non-rotatable.
  • the stop for the opening path of the clamping screw can be formed in a simple manner by a wall part of the housing without the need for additional elements.
  • the opening path of the clamping screw is dimensioned so that the clamping screw remains in the open position in the bore of the first clamping plate and does not protrude beyond the clamping surface of the first clamping plate.
  • the second clamping plate which is non-rotatable and displaceable in the axial direction of the clamping screw, is held in the maximum open clamp position by a resistor is, this maximum opening position is guaranteed and the insertion of the cable or the cable lug is facilitated in this position of the screw terminal.
  • the second clamping plate can no longer fall to the first clamping plate by gravity and thus block the insertion of the cable or the cable lug.
  • a resistor also holds the second clamping plate in the maximum open clamp position.
  • This resistance can in a simple manner be a frictional resistance which is sufficient to hold the second clamping plate in its maximum opening position, which is determined by a stop on the housing, but can be easily overcome when the clamping plate is moved.
  • the fiction, contemporary design of the screw terminal consists essentially in that the clamping screw can be screwed into the bore of the first clamping plate.
  • the fact that the dimensions are chosen so that the clamping screw grips the thread of the second clamping plate when screwing in completely through the first clamping plate enables the clamp to be closed.
  • the bore of the first clamping plate is formed without a nut thread and the first clamping plate has inwardly projecting, thread parts forming projections which in places engage in a thread of the clamping screw with play.
  • This has the advantage that the projections allow the clamping screw to be screwed in until the second clamping plate is reached, but nevertheless release such play that the clamping screw can easily grasp the first thread of the nut thread of the second clamping plate.
  • these projections are completely released by the fact that the shaft of the clamping screw is designed to have a smaller diameter in the area of the screw head, so that the complete screwing of the second clamping plate is not hindered.
  • the second clamping plate can have at least one in the axial direction Clamping screw, perpendicular to the clamping surface, have angled tab which is guided between the guide surfaces of the housing lying in the axial direction of the clamping screw and the tab is clamped with frictional engagement between these guide surfaces and in order to limit the friction to a small extent, these guide surfaces can have projections which clamp the rags under friction.
  • resilient claws can be connected to the first clamping plate, the ends of which are curved in the direction of the axis of the clamping screw and overlap the second clamping plate and hold them back elastically in the maximum open position of the clamp. This would hold the second clamping plate more securely in its stop position on the housing and the resistance when moving this clamping plate is easier to set.
  • projections can be formed, for example, on projections on the threadless bore wall of the first clamping plate or by a burr which is cut by the clamping screw.
  • the arrangement is such that the projections engaging in a thread of the clamping screw are formed on an elastic disk connected to the first clamping plate, preferably made of spring plate, which is provided with a bore whose diameter is less than the outer diameter and larger than the core diameter of the screw thread of the clamping screw, from which some radial slots originate, which subdivide the inner region of the disk into tongues which engage in at least one screw thread of the clamping screw.
  • This elastic disc is preferably attached to a surface of the first clamping plate, for example by spot welding.
  • Hiebei can be attached to the clamping surface of the first clamping plate according to the invention and it can be the resilient claws which the second Grip over the clamping plate in its fully open position, consist of one piece with the spring washer.
  • This resilient disc can preferably consist of beryllium bronze, which has good electrical conductivity and good elasticity.
  • Hiebei is expedient that the edge of the bore in the first clamping plate on the side facing the elastic washer is rounded or provided with a conical countersink in order to allow the tongues formed on the washer to deflect into the thread of the clamping screw.
  • the distance of the stop limiting the opening movement of the clamping screw, formed by a wall part of the housing, from the first clamping plate is dimensioned such that in the stop position the clamping screw plunges into the bore of the first clamping plate, but at least not significantly protrudes the clamping surface of the first clamping plate.
  • the clamping screw can be screwed into the projections of the bore of the first clamping plate until the clamping screw engages the second clamping plate.
  • the housing in the axis of the clamping screw can have an opening for the passage of a screwdriver, the smallest dimension of which is smaller than the diameter of the head of the clamping screw, so that the edge of this opening itself forms the stop for the opening path of the clamping screw.
  • the advantage is achieved that the clamping screw is captive and is protected via this counterbore.
  • the axial length of the threaded part of the clamping screw is greater than the axial distance of the clamping surface of the second clamping plate from the ridge or the inwardly projecting projections or the elastic disc of the first clamping plate or with the clamp open to the maximum Clamping screw with security through the Opening of the first clamping plate can be screwed in until the second clamping plate is gripped at the maximum open position of the clamp.
  • the free end of the shaft of the screw is designed as a threadless centering pin, so that the detection of the thread of the second clamping plate is secured.
  • the bore of the second clamping plate is designed with a normal screw thread.
  • the play between the rigid projections or the burr of the first clamping plate and the thread of the clamping screw is expediently dimensioned such that the projections or the engaging burr engaging in a thread turn of the screw lie on a clear diameter which is preferably at least 30% 40 to 70%, the difference between the core diameter and the outer diameter of the screw is greater than the core diameter of the screw.
  • FIG. 1 shows a switching plane of a packet switch equipped with screw terminals according to the invention in cross section
  • FIG. 2 shows a radially slotted spring plate disk for forming projections engaging in a thread of a clamping screw in plan view according to arrow II in FIG. 1.
  • 3, 4 and 5 show a modified embodiment of the screw clamp, wherein FIG. 3 shows the screw clamp in the open position and FIG. 4 in the closed position and FIG. 5 shows the resilient disk according to FIGS. 3 and 4 in a view from below.
  • 6, 7 and 8 show yet another embodiment of the clamp, wherein FIG. 6 shows a section along line VI-VI in FIG. 7, FIG. 7 shows a section along line VII-VII in FIG. 6 and FIG shows a perspective view of the first clamping plate according to FIG. 6 from below.
  • a packet switch of which a switching level is shown in cross section in FIG. 1, has a number of cams 1 which can be actuated by means of a common shaft and which actuate spring-loaded contact bridges 4, 5 via plungers 2, 3.
  • the fixed contacts 6 and 7 assigned to the contact bridge 4 are provided with screw terminals.
  • Each screw terminal essentially consists of a clamping screw 8 as well as a first clamping plate 9 connected to the fixed contact 7 and a second clamping plate 11 which is displaceably and non-rotatably guided in the housing 10 of the switching plane.
  • the guides arranged in the housing 10 for the axial, non-rotatable displacement of the second Clamping plate 11 are not shown.
  • the shaft of the screw 8 is offset in a region 12 adjacent to the head to a smaller diameter, for example to the core diameter, the axial length of this region of the shaft corresponding at least to the thickness of the first clamping plate 9.
  • a threadless centering pin 13 is formed at the free end of the shaft of the screw 8.
  • inwardly projecting projections 14 are formed in the bore for the screw 8, which engage in a thread of the threaded portion of the screw 8 with play and perform the function of a nut thread.
  • These projections 14 can also be formed by a ridge which is cut by the clamping screw 8.
  • FIG. 2 In the upper left quadrant of FIG. 1 and in FIG. 2, another embodiment of the projections for holding and guiding the screw 8 on the first clamping plate 16 is shown.
  • the first clamping plate 16 is provided for the passage of the screw 8 with a threadless bore 17, the diameter of which allows the threaded portion of the screw 8 to pass with play.
  • a washer 18 made of spring plate is provided here, which bears on the side of the first clamping plate 16 facing away from the second clamping plate 11 and is fixed along its outer edge with a few welding spots 19 on the first clamping plate 16.
  • the clamping screw 8 can also be pressed in a ratchet-like manner between these elastic projections without exerting a rotary movement in the radial direction until the centering pin 13 enters the threaded bore of the second clamping plate 11, after which the screw clamp is then tightened by turning the screw 8.
  • the housing 27 made of insulating material or plastic is formed with a slot 30.
  • the second clamping plate 29 has a vertically angled tab 28, which extends in the axial direction of the clamping screw 8 and dips into the slot 30. In this slot 30, the tab 28 is guided with friction.
  • elevations 31 On the inside of the wall of the slot 30 are elevations 31 which are integral with the housing exist, arranged, between which the tab 28 is guided with friction. These projections 31 make it easier to adjust the amount of friction.
  • the complete opening position of the second clamping plate 29 is determined by a stop 36 formed in the housing.
  • the first clamping plate 32 is again non-rotatable and axially immovable, while the second clamping plate 29 is non-rotatable and axially displaceable by the tab 28.
  • the elastic disk 33 is now arranged on the side of the clamping surface of the first clamping plate 32 and, as shown in FIG. 5, is riveted to the first clamping plate 32 at 35.
  • These rivets 35 can either be designed as continuous rivets or they can be formed by projections of the first clamping plate 32, which are riveted after the elastic washer 33 has been put on.
  • the elastic disk 33 again has a central bore, from which slots 37 extend, which subdivide the edge of the bore into tongues 34.
  • Six tongues 34 are arranged here, and the slots 37 are of such a width that the tongues 34 do not abut one another. This makes it easier to screw in the clamping screw 8, with the tongues 34 being bent.
  • the second clamping plate 43 of the fully open position is held back against the stop of the housing which limits the opening movement not by friction but by resilient claws 40.
  • These resilient claws 40 are on two opposite sides arranged and have at their end an inwardly projecting curvature 41 which overlap the edge of the second clamping plate 43.
  • the housing has recesses 42 in order to allow the ends of the resilient claws 40 to rebound.
  • the resilient claws 40 are formed in one piece with the resilient disk 39.

  • the second clamping plate 43 is shown in plan view, the housing 47 consisting of insulating material or plastic being shown in partial section.
  • the resilient claws 40 are arranged on opposite sides of the second clamping plate 43.
  • projections 45 are also arranged on the clamping plate, which are guided in grooves 46 of the housing 47 running in the axial direction of the clamping screw 8 and ensure that the second clamping plate 43 cannot be rotated. In this way, the cable or the cable lug can be easily inserted in the direction of arrow 44 between the first clamping plate 38 and the second clamping plate 43 when the clamp is open.
