  • the bracket half-sections 44 are each formed of a generally U-shaped body portion having a pair of legs 52, 54 which are interconnected by means of a base 56. Extending from the leg 54 in a plane parallel thereto, but having a slightly smaller width, is a tongue portion 58.
  • the leg 52 has a raised portion 62 which as can be clearly seen in FIG. 5 allows the tongue 58 of one bracket half-section to be inserted into a groove 64 of the other half-section formed by raised portion 62.
  • the rear portion of the U-shaped members 42 are concentrically mounted within the U-shaped body portion of the halfsections 44 and are soldered or welded thereto as at 65.
  • an interconnecting support 68 Extending rearwardly from the base 56 of the bracket is an interconnecting support 68 which is centrally tapped as at 72.
  • the support 68 may be formed from an integral stamping of the bracket 26 and formed by bending the support back between the legs 52 and 54 of the bracket as shown in FIGS. 3 and 6.
  • the holder 28 is formed of right hand section 82 and a left hand section 84.
  • the sections 82 and 84 contain a pair of parallel positioned rear ends 86, 88 which are joined together at their inner facing surfaces as by soldering or brazing. Extending forward from the rear ends of the holder, each of the sections 82, 84 diverge outwardly as at 92, 94, respectively. Transverse openings 96 are formed at the front end of each of the sections 92, 94, the opening 96 shown more clearly in cross section in FIG. 9.
  • the section 102 has a height one-half the height of the section 92, the reduced height being formed by the bottom half of the wall being removed, while the section 104 has its top half removed so as to allow the sections 102, 104 to intersect and cross each other.
  • the diverging sections 102, 104 are once again at their full height as at 106, 108, respectively.
  • the sections 82, 84 extend as forward portions 112, 114 in parallel planes. Near the front end of the portions 112, 114 an opening is provided for set screw 116 which secures one of the holder sections to each of the brackets 26 at the tap 72.
  • a first transverse knurled portion 122 is provided, extending from the top surface of the portion 114 towards the portion 112.
  • a second transverse knurled portion 124 is mounted approximately in the center of the section 112 and extends towards the front portion 114.
  • the front end of the knurled portion 122 is adjacent the rear of the knurled portion 124.
  • Each of the knurled portions 122, 124 is formed integral with the top surface of the respective portions 112, 114, respectively.
  • the tip protector 32 is normally formed from molded rubber and has a pair of strap portions 134 which have a gripping surface 136 formed on the front outer surface thereof.
  • a tit 138 extends transversely from the front inner end of each of the strap portions 134 and allow the straps to be fastened to the holders 28 with the tit 138 extending through the opening 96 of the holder.
  • the rear end of the tip protector is formed of a generally enlarged semincylindrical portion 142, with the rear ends of the straps 134 integral with the outer surface of portion 142.
  • the end 144 of the portion 142 which is adjacent the straps 134 contains a slotted portion 146 having a central circular opening 148 whose diameter is greater than the width of the slotted portion 146.
  • the tip protector is pivotable about the tits 138 and allows the portion 142 to be mounted over the ends 86, 88 of the rear part of the holder 28 when the tool is in operation as depicted in FIGS. 1 and 2. In this position, ends 82 are secured in the slot 146. Further, as can be clearly seen in FIG. 7, when the tool is not in use, the tip protector can be rotated so that the front end of the nose portions 34 are mounted in the circular opening 148.
  • FIGS. 13 there is shown an electrical connector member 150 having an insulator 152 mounted therein.
  • the insulator 152 has a plurality of passageways 154 extending therethrough. Each of the passageways may contact a contact retention clip 156 therein of the type depicted in US. Pat. No. 3,158,424.
  • the clips 156 contain a plurality of inwardly extending tines 158.
  • An electrical contact 162 having a front contacting portion 164 is secured at its rear end to a barrel portion 166.
  • the rear end of the barrel portion 166 is secured to a flange member 168.
  • Extending rearwardly from the flange member is a crimp or solder body portion 172 to which the bared portion of a conductor 174 is secured.
  • the contact 162 is normally mounted in the insulator 152 in such a manner that the front surface of the flange member 168 abuts a rearward facing shoulder 176 of the insulator and the rear face of the shoulder abuts the tines 158, thus preventing the contact from moving axially in the insulator.
  • the front end of the tool is separated, as shown by the dotted lines.
  • the tool is made of a spring-like material so that a spring insert is not necessary.
  • a spring member could be inserted, most likely between the tits 138 so as to allow the tool to remain nonnally closed in the position shown in FIG. 1.
  • the tip 24 and bracket 26 may be replaced by removing the bracket and tip by means of the set screw 116.
  • An insert tip is identical to the extraction tip, the only difference being that for a given size contact and connector the thickness of the tip 34 is reduced a sufficient amount so that the outer diameter of the tip is less than the outer diameter of the flange member.
  • the tool and contact are substantially identical to that shown in FIG. 13.
  • the tines 158 will abut the rear surface of the flange 168. Withdrawal of the tool will then allow the contact to be in the position as shown in FIG. 11.
  • a contact insertion-extraction tool comprising:
  • each of said portions haying a rear end, the rear end of each of said portions being secured to a bracket, means on each bracket for providing alignment of said portions when said portions are in a first position which defines said cylinder;
