  • This invention relates to electrical connectors and more particularly to electric connectors which are rugged in construction and highly reliable in operation under severe environmental conditions, which have a long operating life and which are readily serviceable.
  • the invention was evolved with the general object of providing connectors suitable for use in aircraft, especially supersonic aircraft. In such applications, reliability is extremely important and environmental conditions are severe, particularly with regard to extremes in temperatures, shocks and vibrations and exposure to fuels, oils, solids and other fluids used in aircra. It will be understood, of course, that although the connectors of this invention were designed for such applications, the principles and features of the invention are not limited thereto and may be used in various other applications.
  • connectors ofthe type to which this invention relate include pairs of mating electrical contacts supported in aligned passages in dielectric members which are supported within hollow shells of the connector plug and yits receptacle respectively and adapted to be secured together to bring the mating ends of the contacts together, the opposite ends of the contacts being electrically connected to the ends of wire conductors.
  • One difculty with connectors of the prior art arises with regard to the provision of seals between the dielectric members for the purpose of preventing entry of fluids into the space around the electrical contacts and to prevent failure of the connectors or electrical leakage between the several contacts thereof or between the contacts and the outer conductive shells.
  • An object of this invention is to provide electrical connectors which overcome the disadvantages of prior art connectors and in'which environmental sealing is obtained in a highly reliable manner despite extremes of operating conditions.
  • a more specific object of the invention is to provide electrical connectors wherein the entire dielectric insert of both the plug and the receptacle may be homogenous throughout and characterized by absence of any type of transverse surfaces, or bonding layers other than at the parting line of separation between the plug and the receptacle while at the same time utilizing no elastomers.
  • a further object of the invention is to provide electrical connectors which can be readily serviced and in which contacts can be removed and replaced without destruction of other parts.
  • An important feature of the invention relates to a monodielectric" construction in which each one of a pair of contact-supporting dielectric members is in the form of a single homogeneous member and in which reliable sealing is achieved without the use of separate sealing members bonded to or otherwise associated with the dielectric member.
  • This feature makes possible a simplified and economical construction. It also makes it possible to eliminate the use of elastomers in the connector and eliminates the problems encountered with the use of elastomers.
  • the dielectric members along the parting line between the plug and its receptacle have end surfaces which are held together in pressure engagement when supporting shells are secured together and the contiguration of the end surfaces and the characteristics of the material of the dielectric members are such as to provide a highly reliable fluid seal about aligned contact passages in the dielectric members while at the same time providing rm mechanical support for the contacts.
  • each of the dielectric members is of a substantially homogeneous semihard material, i.e., a material having an elasticity which is less than that of elastomers while being greater than that of ceramic materials, examples of preferred semihard materials being set forth hereinafter.
  • the end surfaces of the dielectric members include planar portions of substantial areas in surrounding relation to the contact passages, such planar portions being firmly engaged when the shells are secured together and being operative to prevent the formation of fluid-entrapping pockets so as to prevent corona discharges.
  • a further specific feature relates to the formation of the end surfaces of one or both of the dielectric members with an integral riser about one end of each pair of aligned contact passages, the riser being adapted to telescope within an end portion of the other passage.
  • an outer surface portion of the riser and an inner surface portion of the other passage are in pressure-sealing engagement.
  • One of the interengaged surface portions is preferably frustoconical in shape to facilitate alignment and sealing.
  • the outer surface of the riser is frustoconical and the riser is surrounded by a planar surface portion, with dimensions such that the highest pressure is applied at the base of the frustoconical surface of the riser while also applying substantial pressure between the interengaged planar surfaces.
  • Another feature relates to a coupling ring and spring assembly for providing the required pressure engagement between the end surfaces of the dielectric members.
  • the coupling ring and one of the shells have stop surfaces of which interengage in a manner to cause the spring means to exert a predetermined engagement force between the end surfaces of the dielectric members.
  • the arrangement serves to maintain a highly reliable seal despite shocks and vibrations and despite expansion and contractions caused by temperature variations.
  • a further important feature of the invention relates to the locking of a contact member in a passage of a dielectric member by means yof a retention member having spring fingers, the retention member being of a hard metal material and the contact being of a soft metal material.
  • the contact can be readily driven out without using special tools and replaced with a new contact. This can be accomplished without destruction of the retention member or the dielectric and it is not necessary to scrap the entire connector.
  • special tools are available, the contacts can be removed without destruction and it is preferable that such special tools be used. In many cases, however, they are not available.

  • the basic polymer structure consists of phenyl and biphenyl units linked by oxygen and sulfone groups.
  • the nonaliphatic character of this structure is responsible for its resistance to oxidative attack at high temperatures while its aromatic nature contributes to strength at high temperature.
  • the flexural modulus of elasticity of the material varies from about 400,000 pounds per square inch at about 70 F. down to about 250,000 pounds per square inch at 500 F. and the tensile modulus and compressive modulus are comparable.
  • the polymer 360 material is particularly suitable where the environmental conditions of operation vary widely and especially where the connector must be operable continuously at relatively high temperatures. If the requirements are not so severe, other materials may be used. For example, a semihard rubber material having a modulus of elasticity on the order of 300,000 pounds per square inch may be used when operation at high temperatures is not required.
  • the surfaces 49 and 50 include planar portions 5l and 52 of substantial area which surround the ends of the contact passages, the planar portions 51 and 52 being brought into tinn pressure engagement when the connector is assembled and being operable to provide a sealing action and also to prevent the formation of fluid-entrapping pockets.
