Definitions

  • connection are so constructed that a relatively high unit pressure is required to insert a plug into the female connector. This can occasion a disconnect force of equal or substantially greater magnitude.
  • a connector of this type is set forth in copending application, Serial No. 772,000, filed (now abandoned), in the name of Kenneth J. Arkwright, entitled Helical Disconnect.
  • FIGURE 1 represents a front plan view of a tool embodying the invention herein, showing it in an initial position for connecting or disconnecting an electrical connector;
  • FIGURE 2 s a view similar to FIGURE 1 showing the tool in its final position
  • FIGURE 3 is an exploded perspective view similar to FIGURE 1;
  • FIGURE 4 is a sectional view of the connector shown in FIGURES 1 and 2.
  • the tool includes a pair of bifurcated handles and 12 commonly pivoted by a pin 14.
  • a spring 16 normally urges the handles to open position.
  • the head portion of the handle 10 includes a yoke-like construction defining a pair of arms 18 and 20.
  • the arms taken in combination with handle 10 constitute a Y-shaped member.
  • the other handle 12 has a quadrilateral head 22 which intersects the angle formed by the Y-shaped handle 10.
  • a carriage 24 is pivotally secured to the arm 18 of the handle 10 by means of a pivot pin 26.
  • the carriage 24 comprises a flat plate 25 with an elongated slot 28 in the plate 25, which permits a fixed pin 30 on the head 22 to slide therein to form a lost motion connection.
  • a similar carriage 36 with a plate 37 is secured to the arm 20 of the handle 10 by pivot pin 38.
  • An elongated slot 40 in the plate 37 in the carriage 36 retains a fixed pin 42 secured to the head 22 to provide another lost motion connection.
  • Fingers 44, 44 on the carriage mate with fingers 46, 46' on the head 22 to engage a disconnect type connector (FIGURE 4) for assembling it.
  • the fingers 34 and 46 on the head 22 are at substantially right angles to each other. Each of these fingers cooperate with "ice similar fingers on the respective carriages to provide a straight-line sliding action between them.
  • the fingers 32 and 34' are positioned so that the distance between them is less than the distance between a pair of flanges on the connector, when the tool is in open position.
  • the fingers 44 and 46 are disposed at a distance which is greater than the flanges on the connector when the handles of the tool are in open position.
  • a pair of adjustable stops 48 cooperate with lugs 50 to control longitudinal travel of the carriages.
  • the reference numeral 102 denotes the male or pin section of the connector and the numeral 104, the female or receptacle section.
  • the male section comprises a cylindrical pin portion 106 of substantially uniform diameter along its length and having a tapered nose 108 on its end.
  • the opposite end of pin portion 106 merges with a shoulder 110 defined by a conical collar 112.
  • This conical collar defines the end of a wire receiving portion 116 and a second conical collar 114 is also provided adjacent collar 112 for cooperation with the insulating sleeve used with the connector as described below.
  • the portion 116 of the male section is centrally bored at 118 to a diameter sufficient to receive the wire with which the connector is designed to be used, and the open end is bell-mouthed at 120 to facilitate insertion of the wire which may be crimped therein.
  • the female section 104 comprises a receptacle portion 122 which is internally bored at 124 to receive pin portion 106 and is helically slotted as shown at 128.
  • the open end of bore 124 is enlarged as by a taper shown at 126 to facilitate the alignment of the parts and the insertion of the pin into receptacle portion 122.
  • the wire receiving portion of the female receptacle is similar to that of the male pin and will not be described.
  • the male pin has a surrounding insulating jacket 138 with a flange or collar 141 adapted to cooperate with the fingers on the assembly tool.
  • the insulating jacket telescopes inside the insulating jacket 136 on the female receptacle which also has a flange or collar 154 for cooperation with the fingers of the assembly tool. Since the internal cooperation of the connector is described in the prior-mentioned application, it will not be repeated here.
  • the connectors are positioned with the fingers 32 and 34 between the flanges on the connector.
  • Closing the handles 10 and 12 causes the arm 18 and the head 22 to move relatively away from each other.
  • the arm 18, by means of pin 26, takes the carriage 24 along with it. This movement is permitted by the lost motion connection between pin 30 and slot 28.
  • the handles 10, 12 generate a high mechanical advantage so that the fingers 32 and 34 pry the connector apart.
  • a tool for assembling and disassembling separable connectors including a pair of bifurcated handles, means pivoting said handles together, a yoke-shaped head member rigidly secured to one of said handles, a carriage pivotally secured to one arm of said yoke, means on said carriage adapted to grasp said electrical connector, a second head member disposed on said other handle so as to bisect the angle formed by the yoke, means on the second head member also adapted to grasp a part of said connector, said means on the head member and said means on the carriage being disposed a distance less than the length of the connector in closed position, a second carriage on the other arm of the yoke, means on said second carriage adapted to bear against the connector, a second means on said other head member also capable of bearing against the connector, said second means and said means on said second carriage being normally disposed a distance greater than the length of a connector in open position, whereby the tool is adapted to disassemble the connector When the connector is assembled, or to assemble the connector when the connector
  • the device of claim 1 including means on the second head member having a lost motion connection with the first carriage and also means on a second head member for forming a lost motion connection with said second carriage, whereby the carriages are adapted to travel longitudinally with respect to the head member.
  • a tool of the character described including a pair of bifurcated handles, means pivoting said handles for relative motion, a head member on one end of each of said handles, a first head member on one of said handles having a pair of arms angularly disposed, a second head member on the other of said handles positioned between the arms on the first head member, means on each of said head members for joining or disconnecting a separa-' ble electrical connection, said means comprising a pair of fingers on one arm of the first head member cooperat-' ing with a pair of fingers on the second head member, and a second pair of fingers on the second head member which cooperates with a second pair of fingers on the other arm of the first head member.
