Definitions

  • the invention refers to a tool for the contemporary crimping of a plurality of insulated wires in an electrical connector.
  • electrical connectors which are adapted to receive a multiplicity of insulated wires in order to terminate a plurality of electrical contacts. It is further known to establish the connection in that the connectors are provided with U-shaped insulation displacement contacts into which the wires are pressed. The insulation displacement contacts are located in a retaining body into which the individual wires are inserted. A pressing member or cover cooperates with the retaining body in order to press the individual wires contemporaneously into the U-shaped insulation displacement contacts.
  • the invention provides for a tool wherein insulated wires can be pressed into connectors of different height.
  • the pressing member is adapted to be displaced by predetermined steps relative to the splice head independent from the transmission means.
  • the actuation of the manual lever leads to a displacement of the pressing member relative to the splice head.
  • This displacement cannot be used for an adaptation to the height of the connector because a predetermined stroke is necessary in order to press the inserted wires fully into the contacts.
  • a locking means or other means are applied to avoid a further displacement of the pressing member.
  • such a limitation of the stroke is also provided.
  • One embodiment of the invention provides that at least an intermediate member is linked to the rear side of the pressing member rotatable about an axis. In different positions, the intermediate member coacts with a transmission lever actuated by the manual lever, with the pressing member having a different distance from the transmission lever in the individual rotational positions of the intermediate member.
  • the intermediate member can for example be mounted on an eccentric member. The eccentric member can be actuated externally by a lever and for example effect two positions of the pressing member.
  • the intermediate member has a plurality of recesses at the circumference thereof which may be engaged by a trunnion attached to the transmission lever, with the recesses having a different spacing from the rotation axis of the intermediate member.
  • the number of displacement steps of the pressing member corresponds to the number of recesses.
  • the splice head has teeth at opposite sides, and the tool has pivotally supported levers including also a tooth which coacts with the teeth of the splice head.
  • the pitch of the teeth can be selected such that the spacing between two adjacent teeth corresponds to the difference in the height of the two different connectors. For connector combinations between these height values, an adaptation can be carried out by a displacement of the pressing member, e.g. by the described eccentric member.
  • the tool 10 shown in Fig. 1 includes a housing 12 which is depicted partially opened.
  • a first lever 14 is fixedly attached to the housing while a second actuation lever 16 is linked to housing 12 at 18.
  • two parallel spaced extensions 20, 22 are provided which cooperate with a splice head indicated at 24.
  • An accommodation plate 26, or retaining member, of splice head 24 is shown onto which an electrical connector (not shown) can be placed.
  • Plate 26 has recesses 28, 30 at opposite ends which are engaged by lower arms 32, 34 of levers 36, 38 by means of pins 40, 42 thereon in order to attach tool 10 to splice head 24.
  • Fig.lA at the right side of Fig.
  • An elongated pressing member 50 which extends approximately parallel to accommodation plate 26 is linked to two sector-like intermediate members 56, 58 at 52,54.
  • the intermediate member 56,58 can be rotated by a square neck 60, 62, for example by a suitable wrench so that various recesses 64, 68 at the circumference of the intermediate members 56, 58 may be engaged by trunnions 70, 72 of links 74, 76.
  • the links 74, 76 are linked the transmission means, including a rack 82, at 78, 80 displaceably supported in housing 12 parallel to pressing member 50.
  • the levers 74, 76 are further coupled by a connecting lever 84 which is coupled to pressing member 50 through a spring 86.
  • the rack 82 is moved parallel to the pressing member by a ratchet lever 88 having a toothed end linked to actuation lever 16.
  • a spring-biased locking lever 90 also having teeth meshing with the teeth on the rack 82 in each position.
  • the pressing member 50 makes a predetermined stroke while a limitation of the stroke for example can be achieved by stop means cooperating with rack 82. If the crimping operation is finished, stop lever 90 is actuated so that rack 82 is moved back by the spring bias in the position shown in Fig. 1. In order to remove the connector, levers 36, 38 are tilted so that the tool 10 can be released from splice head 24. Thereafter, the connector can be removed from splice head 24.
  • the tool 100 shown in Fig. 2 includes a housing 102, an actuation lever 104 fixedly attached to housing 102 while a further actuation lever 106 is linked to housing 102 at 108.
  • the housing 102 is depicted partially opened in order to more clearly show the transmission mechanism.
  • a splice head 110 has a retaining member in the form of an accommodation plate 112 for the accommodation of a connector not shown.
  • a rack each having parallel teeth 114, 116.
  • Levers 122, 124 are linked to opposite sides of housing 102 at 118, 120.
  • One arm of the levers 122, 124 defines a handle 126, 128 while the other arm 130, 132 is also provided with teeth cooperating with the teeth 114, 116 of splice head 110.
  • a predetermined spacing "h" of the pressing member 134 from the upper side of accommodation plate 112 can be adjusted.
  • the pressing member 134 is U-shaped in cross section and linked to housing 102 by means of an eccentric bolt 136.
  • the housing includes two opposite plates 138, 140.
  • the eccentric bolt 136 is connected with a hand lever 142 so that spacing "h" can be changed by a tilting of lever 142.
  • the eccentric bolt 136 has an extension 144 linked to a gear segment 148 at 146 (see Fig. 2), with the gear segment 148 rotatably supported by housing 102 at 150. It includes a pinion 152 cooperating with a slot 154 of housing 102 indicated by dashed lines.
  • the transmission means for pressing the member 134 against the plate 112 includes a ratchet lever 156 which is linked to actuation lever 106 so that an actuation of lever 106 leads to a rotation of gear segment 148 counter-clockwise.
  • a spring-biased locking lever 158 secures the position of the gear segment 148.
  • a tool 100 is shown in connection with connectors v1 to v4 of different height accommodated by a splice head 110.
  • the connectors v1 and v2 of Figs. 6 and 7 have a difference in height of for example 6 mm.
  • the difference in height between the connectors v3 and v4 of Figs. 7 and 8 amount for example to 1,3 mm.
  • a tilting of hand lever 142 and thus a rotation of the eccentric bolt 136 about 180° results in a displacement of the pressing member 134 about 1,3 mm.
  • Figs. 5 and 6 are 10,1 and 11,4 mm, respectively, and regarding Figs. 7 and 8 16,1 and 17,4 mm.
  • the toothing of levers 122, 124 engages the lowest area of toothing 114, 116 of splice head 110.
  • the engagement is offset about one tooth pitch. This corresponds to a change in the spacing between pressing member 134 and plate 112 in the amount of 6 mm. If lever 142 in Fig. 7 is tilted about 180° according to Fig. 8, pressing member 134 is lowered about 1,3 mm. The lowering of pressing member starts, however from a changed position which is about 6 mm higher that of Figs. 5 and 6.
  • connectors of four different heights can be handled by tool 100. If the toothing 114, 116 of levers 122, 124 engage the toothing of splice head 110 further upwardly, connectors with larger heights can be dealt with also.
  • pressing member 134 is biased by springs 160, 162 towards the eccentric bolt 136 in order to give the pressing member 134 a defined vibration-free position.
