Definitions

  • a sealed electrical connector comprises a plastic housing having one or more electrical contact terminals mounted therein.
  • the housing is of a hard poly- CCII iii/[229311; meric material which is elastically deformable.
  • the [58] Fie'ld "339/5962 contact terminals are driven into cavities in the hous- 339/153 210 ing and have peripherally extending teeth. The teeth deform the cavities in the walls which elastically bear against the teeth and form an extremely tight seal be- [56] References Cited tween the opposite faces of the housing.
  • This invention relates to sealed electrical connecting devices of the type comprising a housing through which one or more electrical contact terminals extend. Connectors of this type are adapted to be disengageably coupled to complementary connectors to form disengageable connections between conductors to which the terminals are attached.
  • the disclosed embodiments of the invention are directed to the achievement of a hermetically sealed connector and will be described with reference to the requirements of hermetic connectors however, the principles of the invention are applicable to connecting devices having a degree of sealing which is less than hermetic.
  • hermetic connectors comprise a metallic shell and an insulating insert in the shell in which the contact terminals are mounted.
  • glass or other ceramic in the insert and to bond the glass to the contact terminals and the shell.
  • a number of specific designs are available but all require this ceramic-to-metal or glass-to-metal seal between the insert and the terminals.
  • Hermetically sealed connectors as described above present substantial manufacturing difficulties requiring, as they do, a careful selection of the materials from which they are manufactured, painstaking preparation of the surfaces of the metal parts for the bonding processes, and firing at an extremely high temperature to bring about the bonding of the parts. It follows that these hermetic connectors are very expensive and are subject to damage for the reason that they require glass seals. It should also be mentioned that the contact terminals are ordinarily of a ferrous alloy rather than a copper or copper alloy for the reason that the terminals must have a coefficient of thermal expansion which is very nearly the same as that of the glass or ceramic. A ferrous alloy terminal is, of course, much less desirable from an electrical standpoint than a copper or copper alloy terminal and the electrical performance of hermetic connectors is thus less than would be tolerated in ordinary electrical connectors.
  • a sealed connector can be achieved with an all plastic connector housing, the plastic being of a hard material which will elastically deform when stressed.
  • the contact terminals are driven or pushed into cavities in the plastic and have surface portions which deform the cavity walls. After the terminals have been pushed to their fully inserted positions, the cavity walls, which were elastically deformed during the driving process, are resiliently urged against the surfaces of the terminals with a stress which produces an extremely high quality seal.
  • the seal can be hermetic if the parts are properly selected as to their materials and are dimensioned in accordance with the principles of preferred embodiments of the invention as described below.
  • a further object is to provide a low cost electrical connector which is hermetically sealed.
  • a still further object is to provide a hermetically sealed connector having copper or copper alloy contact terminals therein.
  • a further object is to provide an improved seal between a block of plastic insulating material and a contact terminal extending through the block of insulating material.
  • FIG. 1 is a perspective view of one form of multicontact electrical connector in accordance with the invention.
  • FIG. 2 is a fragmentary exploded view showing portions of the two housing sections of the connector of FIG. 1 separated from each other and showing an electrical contact terminal in alignment with the cavities in the sections.
  • FIG. 3 is a view showing the positions of the housing sections and a contact terminal extending through the cavities in the housing sections, this view illustrating the positions of the parts immediately before the sections are assembled to each other and to the terminal.
  • FIG. 4 is a view similar to FIG. 3 but showing the fully assembled connector.
  • FIG. 5 is a fragmentary view on an enlarged scale of the circled area of FIG. 4.
  • FIG. 6 is an overall view of the connector parts and the tooling for assembling the parts to each other.
  • FIG. 7 is a sectional view illustrating the manner in which the connector of view 1 is mounted in a wall or bulkhead.
  • FIG. 8 is a cross-sectional view of an alternative form of connector in accordance with the invention.
  • one form of electrical connecting device 2 in accordance with the invention comprises an insulating housing 4 having a plurality of electrical contact terminals 6 mounted therein and extending beyond the faces l4, 14' thereof.
  • the housing as will be explained in more detail below, is of a plastic material which is relatively hard but which is capable of undergoing elastic deformation when subjected to a stress.
  • the housing 4 is formed from two identical or substantially identical, sections 8, 8. In the description which follows, only the housing section 8 is described in detail and the same reference numerals, differentiated by prime marks are used to identify corresponding structural features of the two sections.
  • the housing section 8 has a generally cylindrical body portion 10 having a mating side or face 14 and a rearward face 12.
  • a cylindrical hood 16 extends axially beyond the mating face 14 and surrounds and protects the contact terminals mounted in the housing.
  • This hood has helical threads 18 on its external surface of the type described in application Ser. No. 226,689 so that it can be coupled to a complementary connector having a locking unit thereon.
  • a flange 20 extends from the body portion 10 at the rearward side 12 and has openings 19 in its corners to facilitate mounting of the connector in a bulkhead opening.
  • a plurality of contact receiving cavities extend through the body portion 10 from the side 12 thereof to the mating face 14.
  • Each cavity has a portion 22 of uniform diameter d which extends inwardly from the mating face 14 to an intermediate location in the body 10.
  • This portion 22 of the cavity merges, by means of a conical cavity portion 24, with an intermediate enlarged diameter cavity portion 26 which in turn merges with a second conical cavity portion 28.
  • the conical cavity portion 28 extends to a further enlarged cavity portion 30 which extends to the rearward face 12.
  • the contact terminals 6 of this embodiment are in the form of double ended contact pins each of which has contact portions 32, 32 on its ends, the diameter of these contact portions being no greater than, and preferably slightly less than the diameter d of the cavity portions 22, 22'.
  • the inner ends of the contact portions 32 merge with gripping or sealing portions which have plurality of frusto-conical teeth 34. These teeth have inclined sides 36 which are directed towards the contact portions 32 of the terminal and rearwardly or centrally facing sides 38 which advantageously extend normally of the axis of the terminal.
  • the sides 36, 38 and 36', 38' intersect to define edges 40 which extend endlessly around the circumference of the terminal.
  • the central portion 42 of the contact terminal is of an enlarged diameter but fits easily within the intermediate cavity portion 26 as shown in FIG. 3.
  • the contact terminals can be of a hard copper or copper alloy such as cartridge brass and are advantageously manufactured from bar stock by a screw machine operation in order to produce the sharp edges 40 on the teeth.
  • the connector 2 is assembled with the aid of assembly tools 44, 44' which are simple metal dies dimensioned to fit within the hoods 16, 16' and which have openings 46 extending therethrough that receive the ends 32, 32 of the contact terminals,
  • assembly tools 44, 44' which are simple metal dies dimensioned to fit within the hoods 16, 16' and which have openings 46 extending therethrough that receive the ends 32, 32 of the contact terminals.
  • a pin 6 is located between each pair of aligned cavities with the ends 32, 32 extending through the uniform diameter portions 22, 22 of the housing sections.
  • the assembly tools 44, 44' are then positioned against the mating faces 14, 14 and the assembly of the connector parts and the tools are placed between a pair of plates 48, 48 as shown in FIG. 6.
  • the plates are then forced towards each other by means of a suitable press such as a simple arbor press until the sides 12, 12' of the housing sections are against each other as shown in FIG. 4.
  • a suitable press such as a simple arbor press
  • the teeth 34, 34' deform portions of the cavity walls immediately adjacent to the cylindrical cavity portions 24, 24 and because of the fact that the conical surfaces 36, 36 slope away from the ends of the terminal, the plastic material of the cavity walls will be displaced outwardly and somewhat forwardly towards the mating faces 14, 14. When the sides 12, 12' are against each other, further movement of the parts is stopped and the mounting portions or teeth 34, 34 will be located in the uniform diameter portions 22, 22 of the cavities.
  • the plastic material of the cavity walls elastically flows against the surfaces 36, 36 and into the corners 37 (FIG. defined by the intersections of each surface 36 with the next adjacent surface 38 although it does not necessarily fill all of the space in these corners. There will usually remain a slight void defined by a maniscus of the plastic material.
  • the connector 2 is used on a bulkhead when it is necessary to maintain the one side of this bulkhead at a different pressure from the pressure on the other side.
  • the need for sealed connectors in bulkheads frequently arises in aircraft construction when it is necessary to lead an electrical cable from the interior of a pressurized compartment to an unpressurized zone of the aircraft.
  • the connector is mounted on the bulkhead 50 by forming a hole in the bulkhead, positioning the flange 20 against the bulkhead with the hood 16 extending through the bulkhead and securing the flange to the bulkhead.
  • the interface 54 between the surfaces 12 and 12' is not necessarily hermetically sealed and the central chambers 56 in the connector which surround the central portions of the contact pins will not be tightly sealed from the atmosphere which exists on the righthand side of the bulkhead.
  • the seals in the connector which effectively seal the righthand side of the bulkhead from the lefthand side are those seals between the lefthand portions of the pins and the housing section 8. If the connector were mounted on the lefthand face or side of the bulkhead 50, the seals on the righthand portions of the terminals would be effective to prevent the passage of gasses between the two chambers or compartments.
  • the plastic material for the housing is an important consideration in the achievement of best results in the practice of the invention.
  • Connectors of the type shown in FIG. 2 must be of a material which is hard and firm, at least in a tactile sense; even the hood 16 must be hard and unyielding in normal handling because of the need to provide screw threads on its external surface and a threaded coupling cannot be provided between soft or rubbery pacts.
  • the plastic material of the housing 4 must be capable of undergoing elastic deformation without fracture when the contact terminals 6, 6' are driven into the cavities so that the plastic will resiliently bear against the teeth 34, 34 as discussed above. Accordingly, a suitable material for the housing can be described as being rigid but substantially elastically deformable.
  • a connector in accordance with the invention and in accordance with the dimensions and material discussed above was found to be hermetically sealed within the requirements of an accepted specification Mil C 26500, section 3.6:18.l in accordance with this specification.
  • a connector can be classified as hermetically sealed if When subjected to a pressure differential of 15 psi they shall not exhibit a leakage rate of greater than 0.01 micron of mercury per cubic foot per hour (1 X 10 standard cc per second at one atmosphere). Connectors in accordance with the invention have been found to exceed this requirement by as much as two orders of magnitude.
  • copper or copper alloy contact terminals can be used in the practice of the invention for the contact terminals rather than the ferrous alloy terminals required, for thermal expansion characteristics, in previously known hermetic connectors having glass to metal seals.
  • the practice of the invention thus permits the achievement of superior electrical permission along with the achievement of lowcost sealing.
  • FIG. 8 shows an alternative form of connector 58 having a one piece housing 60 from which a mounting flange 62 extends.
  • This housing has a mating face 64, a rearward face 66, and a plurality of cavities 68 which extend between the faces.
  • Contact terminal pins 70 are mounted in the cavities adjacent to the mating face 64 and have contact portions which extend beyond the mating face as shown.
  • the contact pins are driven inwardly from the mating face side 64 of the housing and have teeth with conical surfaces which slope towards the rearward face. The seal is then obtained in the same manner as in the previously described embodiment.
  • the righthand ends of the contact pins of this embodiment are formed with circumferential recesses 74 and are adapted to be coupled to electrical contact sockets 76 which are crimped onto the ends of wires 78.
  • These sockets are provided with spring detents 80 which are adapted to cooperate with the recesses 74 to disengageably couple the sockets 76 to the ends 72 of the contact terminals in the housing. It will be noted that the length of the connector is such that the sockets 76 will be completely contained in the cavities when the sockets are coupled to the contact pins.
  • the connector 58 can be used under the same circumstances as the previously described embodiment,
  • FIG. 8 is adapted to be directly coupled to a complementary connector plug containing socket contacts.
  • a housing comprising first and second housing parts
  • each of said parts comprising a cylindrical body portion having a mating face and a rearward face, a plurality of contact receiving cavities extending through each of said housing parts, each of said cavities having an enlarged portion extending inwardly from said rearward face and having a constricted portion adjoining said enlarged portion,
