Definitions

  • a preferred embodiment of the present invention utilizes a Mil-C-26500 type electrical connectors having an improved environment resisting rubber grommet, hard dielectric face socket insert and user friendly contact retention clips and ground wave springs on the receptacle connector.
  • the present invention significantly lowers cost in the assembly of connectors and greatly improves the interconnection between the plug and receptacle connectors thereby avoiding discontinuities.
  • Another object of the invention is to maintain Mil-C-26500 connector environment resistivity.
  • a further object of the invention is to ensure proper mating or coupling on the electrical pin and socket contacts when splayed or bent contacts are affected.
  • Yet another object of the invention is to eliminate manufacturers variation on the construction of the contact retention clips and institute ease of assembly or disassembly of the electrical contacts.
  • a still further object of the invention is to provide a set of straight wave spring that becomes effective to assist the connector mounting screws in maintaining a secure ground path on the aircraft connectors that requires electrical bonding.
  • the present invention provides Mil-C-26500 type electrical connectors with improved wire sealing webs, provision of a hard dielectric face socket insert to detect splayed or bent electrical contacts, user friendly retention clips which enhances insertion and removal of contacts resulting to elimination of damaged or push back retention clips and ground wave springs to assure protection against lightning strike and continued system protection against high intensity radio frequency (HIRF).
  • HIRF high intensity radio frequency
  • a connector of this type comprises a rigid shell 1 containing a rubber grommet 2 having formed inside a seal webbing 5, a rigid dielectric contact retainer 3 and a rubber insert 4. These members all being fixedly retained in the shell 1. Also, pictured is an electrical pin contact 6 crimped to a wire 7 with a shrinkable sleeve 8 used to build up diameter of wire 7. The several members 2-5 encompass and hold in place any preferred number of contacts 6, the precise number depending upon the number of wires 7 to be electrically connected.
  • the seal webbing 5 in the rubber grommet 2 ensures an environmentally resistant property of the connector.
  • the existing seal webbing 5 is constructed to accommodate size 20 contact 6,15 on wire 7 with diameter range of 0.040 to 0.090 in.
  • Fig. 2 is illustrative of the present invention environment resisting rubber grommet 2 having seal webbing 5 with a wire seal range of 0.035 to 0.090 in.
  • the shape and size of the seal webbing 5 construction in which the smaller diameter 9 of the seal webbing 5 is now 0.021 to 0.0215 in. but still within the molding elasticity of the rubber grommet 2. Equally important is the addition of a 0.025 to 0.030 in. flat radius 10 on each of the three seal webbings convolutions 11-13, thus securing a much more reliable wire seal.
  • FIG. 3 Another feature of the invention is shown in Fig. 3.
  • conventional connector of this type uses a rubber insert 4 on both the plug 16 and receptacle 17 connectors.
  • a plug 16 connector having socket contact 15 coupled to a receptacle 17 connector having a pin contact 6 can result in improperly mated pin 6 and socket 15 contacts. This condition exists when splayed or bent contacts are mated whereby the pin contact 6 is laying outside or alongside the socket contact 15.
  • Performing a very critical role in the practicing of the invention is a specially configured hard dielectric face insert 14. The hard dielectric face insert 14 is physically added to the existing rubber insert 4.
  • the layer of hard dielectric 14 is substituted to the removed portion of the rubber insert 4.
  • a layer of the hard dielectric 14 is bonded to the rubber insert 4 when the plug connector 16 or receptacle connector 17 has socket contacts 15.
  • the socket contact hole opening 18 in the hard dielectric 14 has a diameter that chamfers down to another contact hole diameter 19 which is smaller in size than the combined diameter of the front ends 27 of the pin -16 and socket 15 contacts. Owing to these dimensional configurations, the inadvertent mating of splayed or bent contacts is eliminated.
  • Figs. 4 and 5 The advantages to be derived from incorporating standardized, user friendly contact retention clips 20 on the Mil-C-26500 connector is graphically illustrated on Figs. 4 and 5. It shall be observed that the contact retention clips 20 hole opening 28 is at the receiving end of a series of predetermined diameters 21-23 designed to lead in pin 6 and socket 15 contacts without interference. Also, attention is called to the positioning 24 and hole opening 25 of the retention clip tines 27. It can be discerned that this construction permits contacts 6,15 extraction with ease.
  • the advantages can be understood as (1) less critical assembly or bonding of the rubber grommet 2 towards alignment with the rigid dielectric contact retainer 3 whereby each component halves or parts 2,3 has plurality of contact holes 29, (2) insertion and removal of contacts 6,15 is vastly improved and (3) construction variations and damage to the contact retention clips 20 are eliminated.
  • each receptacle 17 connector mounting hole 32 is a wave spring 31 adjacent to each receptacle 17 connector mounting hole 32.
  • a wave spring 31 For this illustration but not limited to is a 0.005 in thick BeNi wave spring 31 which is held stationary in a configured dimensioned slot 33. Although, the way it is held stationary is relatively unimportant to a practicing of the invention, it is imperative that its properly adjusted positions, height 34 and length 36, be maintained accordingly to the slot 33 depth 35 and length 37.
  • the wave spring 31 is designed to about 60 percent point of compression or deflection when the receptacle 17 connector is mounted to the aircraft panel and/or structure 38 using mounting screws. It can be understood that the wave springs 31 permits a maintainable, reliable and secure ground path to the mounted receptacle 17 connector.
