Definitions

  • This invention relates to a connector arrangement having at least two interconnectable casing parts and a lever which facilitates an electrical contact between the casing parts against the possibly substantial plug-in resistance and which if required locks the plugged-in casing parts in their plugged-in position.
  • a connector arrangement according to the preamble of claim 1 is known from WO 94/14212.
  • the range of rotation of the lever of such an arrangement is usually limited to an angle of the order of 90°. This feature limits the length of the plug-in path in which the lever can assist the plug-in movement, as will become clear hereinafter.
  • the shape of the slideway can be described in a polar co-ordinates system centred on the pivot pin as function R ( ⁇ ) of the azimuth angle ⁇ .
  • the term "rise of the slideway” is to be understood as denoting the differentiation dR/d ⁇ from the azimuth angle.
  • Fig. 4 shows the operation of a known lever of this kind.
  • the lever is pivotally connected by way of a pivot pin 7 to a first plug part 1.
  • the slideway 10 engages around a sliding member 4 of the second plug part 2 and contacts the same at a place P.
  • the two connector parts are movable relatively to one another in the plugging direction which corresponds to the direction of the connection between the pivot pin 7 and the sliding member 4.
  • the slideway 10 forms an angle ⁇ with the plugging direction at the place P.
  • the force F applied by the slideway perpendicularly to the sliding member 4 can be broken down into an operative component F ⁇ parallel to the direction of movement and a component F perpendicular to the first-mentioned component. These two components are proportional to cos ⁇ and sin ⁇ respectively.
  • the lever of the connector arrangement according to the invention has no fixed pivot pin. Instead, two slideways are provided engaging one each with the respective sliding member of the first casing part and second casing part.
  • the two slideways of such a construction have the same rise as in Fig. 4 relatively to a common centre of rotation, it will be readily apparent that for a given angle of rotation the movement of the casing parts of the arrangement relatively to one another in an arrangement according to the invention is twice that of the conventional arrangement.
  • the rises of the slideways have remained the same the percentage distribution of the forces between operative forces parallel to the plugging movement and unwanted forces perpendicular thereto are the same as in the conventional arrangement.
  • the rise of the slideways of a connector arrangement according to the invention need be only half as much as in a conventional example so that the distribution of the applied force to the effective force and the unwanted force is improved - i.e., the lever is easier to operate. Mechanical stressing is therefore reduced and so the complete connector arrangement can be of lighter construction.
  • the centre of rotation of the lever is defined by a pivot pin guided in guide means which are preferably in the form of an elongate slot oriented in the plugging direction of the arrangement.
  • the arrangement according to the invention can comprise a number of groups of contacts and a number of levers.
  • the groups of contacts can be, for example, conventional connectors which can be combined to form an arrangement by a clip or in the wall of an appliance.
  • the or each guide means and the or each lever can be disposed on the clip and the first sliding member can be disposed on such wall.
  • two plug-in connectors can be disposed on both sides of the lever or associated guide means so as to be movable into contact by operation of just one lever.
  • Groups of contacts can be disposed between two levers.
  • the guide means are side walls of the first casing part into which the second casing part is plugged.
  • Fig. 1 is a view in side elevation of a contact casing 1, the matching element 2 to be plugged into the casing 1, both of them having sliding members 3, 4 in the form of cylindrical parts which project laterally in the viewing direction, and a lever 5 for drawing the two casing parts 1, 2 together.
  • a web 6 which extends in the viewing direction of Fig. 1 the lever 5 shown is connected to a congruent second lever behind it, the latter lever not being visible in Fig. 1.
  • the web 6 and the two levers 5 form a U-shaped member which can engage around the contact casing 1 on two sides, the pivot pins 7 of the levers engaging in corresponding slots 8 in the casing 1.
  • the pivot pins 7 have a stem part whose diameter and length correspond substantially to the width of the slot 8 and the wall thickness of the casing 1 at the edge of the slot 8 respectively, and a head part which is of greater diameter and which moves inside the casing 1 and prevents the pivot pin 7 from escaping axially when stressed.
  • Each lever 5 has two slideways 9, 10 in the form of spiral grooves disposed diametrically opposite one another on either side of the pivot pin 7.
  • One, 9, of the slideways is closed peripherally and is adapted to receive a projection 3 disposed on casing 1 in prolongation of the slot 8.
  • the pins 7 are introduced into the slots 8 until the projections 3 first force the edge zones 11 of the levers 5 away from the casing 1 resiliently and finally engage in the closed slideways 9.
  • each lever 5 can have near the slideway 9 a chamfer or slight outward bend.
  • the second open slideway 10 is adapted to receive the projection 4 of the companion element 2.
  • the companion member 2 can be introduced freely into the casing 1 until the projections 4 which extend through the slots 8 abut the inside of the slideways 9. This state is shown in Fig. 2.
  • the lever 5 is turned clockwise around the pin 7. During the rotation the pin 7 engages to an increasing depth in the slot 8 so that the centre of rotation is displaced continuously in the plugging direction.
  • the projections 3 In the position shown in Fig. 3 the pivot 7, the projections 3 have reached the end of their paths and the contact is in the closed state.
  • the two casing parts 1, 2 cannot be separated from one another in this position unless the lever is turned again or destroyed.
  • Known latching means can be provided to latch the lever 5 in the closed position.
  • the slideways shown in Figs. 1 - 3 have the shape of archimedean spirals.
  • the rise of archimedean spirals is independent of the angle of rotation so that this shape is particularly suitable if the plug-in resistance of the casing parts is operative substantially over the complete relative travel of the lever.
  • the plug-in resistance may be particularly great in places, for instance, when the contact pins of the connector start to enter the associated bushes. In order that this increased resistance may be readily overcome it may be convenient to combine the shape of the slideways, for example, on a number of archimedean spiral sub-elements having different rises, the rise chosen being less according as the resistance to be overcome is greater in order to even out the force required to close the lever and therefore, the mechanical stressing of the connector.
