  • An electrically conducting end portion 22 is provided on the male-contact l8 and is provided with a transverse vent 24 which provides means for tightening the end portion 22 on the male contact 18 with a suitable tightening wrench tool.
  • the vent communicates with the passageway 20 through a passageway 26.
  • the end portion 22 may be threadably secured, as shown in FIG. 5, to the elongated cylindrical male contact l8, and provided thereon with a tapered tip 28 of dielectric material.
  • an external projecting key 30 is electrically secured, as by brazing to the end of the male contact.
  • a generally cylindrical housing 32 has a terminal end 34 and provided with a longitudinal keyway 36 in the cylindrical surface of the housing 32.
  • the keyway 36 terminates in a web portion 38 immediately adjacent to the remaining terminal end 40 of the housing 32.
  • the male contact 18 is assembled internally of the cylindrical housing 32 with the key 30 thereof protruding into and slidably received within the keyway 36. With the key 30 stopped against the web portion 38, inadvertant removal of the male contact 18 from the housing 32 is prevented.
  • the tab 48 registers in the keyway and the elongated fastener 50 protrudes internally of the housing 32 along the longitudinal axis thereof and receives thereover the end portion of the coil spring 42.
  • the coil spring 42 is retained in alignment with the longitudinal axis of the housing 32 and of the male contact 18 bythe fastener 50 and the recess 20 provided in the male contact l8.
  • the terminal end 40 of the housing 32 is formed with pairs of narrow elongated notches, one pair of which is shown at 52. Each pair of notches defines therebetween a relatively rigid finger 54.
  • each finger 54 is formed from a part of the cylindrical surface of the housing 32 and is slightly radially outwardly flared.
  • the terminal ends 56 of each spring finger 54 is recessed from the terminal end 40 of the housing 32.
  • a resilient elongated leaf spring 58 overlies a corresponding finger 54 and is secured thereto by a pair of threaded fasteners 60.
  • the triggering apparatus is indicated generally at 66 and includes a generally rectangular cantilever leaf spring 68 having an upturned marginal edge 70.
  • a dowel 72 is provided with a pair of transverse arcuate surfaced shoulder portions 74 which, as shown more particularly in FIG. 4, register against the upturned margin with a threaded fastener 76 securing the shoulders to the surface of the spring 68.
  • a projecting tapered ear 78 is formed from the central portion of the spring 68 and receives thereover one end of a relatively reduced diameter compressible coil spring 80.
  • a generally annular cap 98 freely receives and guides the male contact 18 through, a central aperture 100 thereof.
  • a generally reduced rectangular aperture 102 freely receives the trigger portion tip 84 therethrough.
  • the cap 98 is mounted in overlying relationship over the terminal end 40 of the housing 32.
  • at least one strand of braided or otherwise flexible electrical conductor material 104 is electrically secured to the protruding key 30 by a weldment 106, for example.
  • the electrical conductor is indicated at 106 and is provided thereover with a layer, of insulation material 108.
  • a connector of any desired type 1 10 is electrically secured, for example by a series of compression crimps 112 to the end of the conductor 106.
  • the remaining end of the conductor 104 is secured to the end of the connector for example by a weldment 114.
  • the connector 1 10 is located in a first cylindrical portion 116 of a shielding housing of generally elbow configuration.
  • the housing 32 and male contact member are located in a second cylindrical portion 118 of the elbow shaped shielding housing.
  • the male contact 18 is first forcibly retracted internally of the housing 32 until the dowel 72 registers within transverse aperture 44. Such retraction is accomplished by use of a specially adapted hand tool or by inserting the connector onto a plugged parking bushing.
  • an operator suitably grasps the loop 14 in the well known manner and registers the tip 28 of the connector in alignment forcibly thrusts the loadbreak connector into mating engagement with the connector 136, with the male contact being received internally of the energized connector and the connector 136 in turn being received internally of the complimentary tapered recess 132.
  • Such engagement of the dowel 72 immediately releases the male contact 18 thereby enabling the compressed coil spring 42 to impel the male contact from a first retracted position to a second extended position and in mating engagement with the connector 136.
  • Such action is accomplished with a speed not heretofore attainable by a static male contact in a loadbreak connector of the prior art.
  • the head 138 of the connector 136 will register against the dielectric cap 98.
  • the vent 24 thereof is substantially internally of the connector 136, such that generated gases which are not dissipated completely in the connector 136, are dissipated through the vent 24 and the passageways 26 and of the male contact into the housing 32 and away from the mating surfaces of the connector 136 and the male contact 18.
  • the spring ends 62 in registration against the collar 64 provide a retaining structure for preventing inadvertant retraction of the male contact from its extended position. More specifically, the annular collar 64 impinges against the spring ends 62, which in turn impinge against the ends 56 of the relatively rigid fingers 54. Such action stiffens the spring ends 62 and prevents inadvertant retraction of the collar 64 past the stiffened spring ends 62. However, when retraction is specifically desired, an operator, by applying a sufficient force, will cause the collar 64 to forcibly bear against the spring ends 62. Such action eventually the collar to pass into the housing 32. The male contact will then be readily retracted into the housing 32 until the dowel 72 registers in the aperture 44 provided in the male contact.
  • the spring ends 62 are not damaged since they are stiffened upon impinging against the ends 56 of the rigid flared fingers 54.
  • the stiffened spring ends 62 will be biased radially outward, and the leaf springs 58 will deform resiliently in cantilever fashion. The extension and retraction cycle of the male contact can be thereby repeated without damage to the retaining structure provided by the springs 58 and spring ends 62.
