Definitions

  • ABSTRACT A low cost sealed electrical connector in which the mating plug and receptacle connector members are each formed of a unitary body of elastic pliant molded material in which mating contacts are mounted in aligned contact passages.
  • the receptacle connector member is formed with a resiliently radially expandable sleeve which slidably receives a forwardly extending annular section of the plug connector member.
  • Such annular section defines a cavity which slidably receives a central projection formed on the receptacle connector member.
  • Either a deformable lip or a plu rality of ribs are formed on the outer surface of the plug annular section which have an interference fit with the inner surface of the sleeve thereby providing a primary interfacial seal therebetween.
  • the projection on the receptacle provides mechanical support for the plug annular section and also is in sealing engagement therewith so as to provide a secondary seal.
  • a lip seal or sealing ribs are formed on the wall of each contact passage to provide a rear seal for the insulated wire which is connected to the contact mounted in the passage.
  • sealed refers to the ability of a connector, that is, the mated plug and receptacle members, to prevent the intrusion of moisture or other contaminants into the area of the connector containing the electrical contacts.
  • a sealed connector In another form of a sealed connector.
  • the entire body of the connector is formed of a plastic material.
  • the central or interfacial seal for the connec tor is provided by the sealing engagement of a forward cylindrical portion of the plug with a cylindrical recess formed in the forward end of the receptacle connector member of the connector.
  • the rear seal that is, the seal between the contact passage and the contact, is provided simply by an interference fit between the mating cylindrical surfaces of the parts.
  • a connector of this particular form is described in U.S. Pat. No. 3,60l,760. Such a connector however is not capable of entirely preventing the intrusion of moisture or other contaminants over a wide variety of temperature and environmental conditions as encountered in automotive vehicles.
  • the interfacial or central seal for this connector is provided separately for each contact pair in the form ofa projection having ribs thereon which have an interference fit with the walls of a recess formed in the mating connector member. While all the aforementioned techniques have been known and utilized, still no connector has yet been devised which adequately prevents the intrusion of moisture or other contaminants into the interior thereof and which is sufficiently low in cost to be practical from an economic standpoint for use on automotive vehicles. It is the purpose of the present invention to provide such a connector.
  • a low cost sealed electrical connector in which the mating plug and receptacle connector members each comprises a unitary body of elastic pliant material with electrical contacts mounted in aligned passages in the bodies.
  • the receptacle connector member embodies a resiliently radially expandable forwardly extending sleeve portion which slidably receives an annular section which extends forwardly from the plug connector member.
  • Annular sealing means is integrally formed on one of the connector members extending radially between the sleeve portion of the receptacle connector member and the annular section of the plug connector member.
  • a projection is formed on the receptacle connector member which extends into the cavity defined by the annular section of the plug connector member.
  • This projection provides a relatively rigid mechanical support for such annular section thus assuring that an effective primary interfacial seal is provided between the mated parts.
  • the projection on the receptacle connector member is in sealing engagement with the wall of the cavity in the plug connector member so that a secondary seal is formed in series with the primary seal. thereby assur ing that contaminants and moisture external ofthe connector will not intrude into the central interior area of the connector containing the electrical contacts.
  • Rear seals for the insulated wires connected to the contacts are provided by either a plurality of ribs or a radially extending lip integrally formed on the wall of each contact passage.
  • a connector embodying the aforementioned interfacial and rear seals has been found to be air and moisture tight over a wide variety oftemperature and environmental conditions.
  • the connector bodies may be molded as unitary parts thereby minimizing manufacturing and assembly costs.
  • FIG. 1 is a partial longitudinal sectional view taken along line l] of FIG. 2 showing mated receptacle and plug members of a connector embodying the features of the present invention
  • FIG. 2 is an end view of the plug connector member illustrated in FIG. I;
  • FIG. 3 is a fragmentary sectional view showing a modified form of the interfacial seal of the invention.
  • FIG. 4 is a fragmentary sectional view showing another alternative form of the interfacial seal of the invention.
  • FIG. 5 is a fragmentary sectional view showing still a further form of the interfacial seal of the invention.
  • FIG. 6 is a fragmentary sectional view showing an alternative form of a rear seal which may be utilized in the connector of the invention.
  • FIG. 7 is a fragmentary sectional view illustrating a modified form of a contact retention element in accordance with the present invention.
  • FIGS. 1 and 2 illustrate a preferred form of the electrical connector of the present invention generally indicated 10.
  • the connector comprises mated receptacle and plug members 12 and 14, respec tively. Except for the contacts mounted therein.
  • each connector member consists of a unitary mass of molded elastic pliant material which is chemically resistant to hostile environments and varying temperature conditions.
  • thermoplastic elastomer such as polyurethane polyester.
  • polyurethane polyester for example could be utilized as the material of the plug and receptacle connector members. It will be appreciated. however, that other elastomers could be utilized if they possess the required characteristics of resiliency, flexibility and softness to produce cffective seals when configured in accordance with the present invention, as will be described later herein.
  • the receptacle connector member 12 is formed with a resiliently radially expandable forwardly extending cylindrical sleeve 16.
  • a central forwardly extending projection 18 is also formed on the receptacle connector member 12 inside the sleeve 16.
  • the outer surface 20 of the projection i8 is spaced from the inner cylindrical surface 22 of the sleeve to define therebetween an annular recess 24.
  • the plug connector member 14 is formed with a forwardly extending annular section 26 which provides a central cavity 28.
  • the projection 18 is slidable received within the cavity 28 and the annular section 26 is slidably received in the annular recess 24.
  • An interfacial seal is provided between the cylindrical inner surface 22 of the sleeve 16 and the cylindrical outer surface 32 of the annular section 26 of the plug connector member.
  • the interfacial seal comprises a plurality of annular ribs 34 integrally formed on the annular section 26 ofthe piug connector member.
  • the ribs extend from the cylindrical outer surface 32 of the plug radially toward the cylindrical inner surface 22 of the sleeve 16.
  • the ribs are dimen sioned so as to have an interference fit with the sleeve 16. Compressive deformation of the ribs, in intimate contact with the smooth cylindrical inner surface of 22 of the sleeve 16, causes an elastic deformation of the sleeve.
  • the outer surface 20 of the projection 18 has a frustoconical configuration which mates with the wall 38 of the cavity 28 in the plug connector member that has a like frusto-conical configuration.
  • the mating frustoconical surfaces 20 and 38 tend to create a wedging action between the annular section 26 and the projection 18 when the plug connector member is mated with the receptacle connector member thereby enhancing the sealing engagement of the ribs 34 with the inner surface 22 of the sleeve 16.
  • the engagement of the mating frusto-conical surfaces 20 and 38 produces a secondary seal in series with the primary seal provided by the ribs 34 thus assuring that air, moisture or other contaminants do not enter the interior of the connector.
  • Latching means. generally designated 40 is integrally formed on the two connector members for releasable holding the same together.
  • Such latching means comprises an integral, radially inwardly extending flange 42 formed on the sleeve 16 adjacent to its outer end.
  • the sleeve is beveled at its inner surface to provide a frusto conical lead surface 44 which facilitates insertion of the annular section 26 of the plug connector member into the receptacle connector member.
  • a radially outwardly extending flange 46 is formed on the plug connector member. This flange is positioned behind the flange 42 when the connector members are mated.
  • the flange 42 provides a rearwardly facing inclined surface 48.
  • a similarly inclined rearwardly facing surface 50 is formed on the flange 46 adjacent to the surface 48. Since the sleeve 16 is resiliently radially expandable. when the plug connector member is initially mated with the receptacle connector member. the flange 42 will ride over the surface of the ribs 38 and the flange 46 until it passes the inclined surface 50 whereupon the flange will contract thereby latching the two connector members together. To separate the connector members. the members are pulled axially apart whereupon the flange 42 will expand radially outwardly due to the engagement of the inclined surface 48 on flange 42 with the inclined surface 50 on flange 46 whereby the latching means is uncoupled thus allowing full disengagement of the connector members. It will be appreciated that due to the resiliency of the sleeve 16, the ribs 34 may be shifted axially with respect thereto during the engaging and disengaging of the connector members.
  • the forward portions of the plug and receptacle connector members are shaped so that the plug connector member fills nearly all the space within the receptacle connector member, namely the annular recess 24.
  • the two halves of the connector are mated. air contained within is caused to be expelled. Displacement of this air within the connector body produces a condition which results in a slightly greater than atmospheric pressure within the connector. This pressure resists ingress of moisture or air into the interior of the connector.
  • the receptacle connector member 12 and plug connector member 14 are provided with a plurality of axially aligned longitudinally extending contact passages 52 and 54, respectively. Three such passages are shown in F107 2 for each connector member by way of example only. Obviously. a greater or smaller number of pas sages could be provided if desired.
  • a socket contact 56 is positioned in each of the passages 52 while a pin contact 58 is positioned in each of the passages 54.
  • one set of aligned passages 52 and 54 are shown without the contacts mounted therein to clarify the disclosure.
  • Each contact terminates an insulated wire 60.
  • the contacts are shown as being of the closed barrel type, the barrel being crimped onto the wire.
  • the contact passages 52 in the receptacle connector member extend through the projection 18 while the contact passages 54 in the plug connector member open into the central cavity 28 of the plug connector member.
  • the pin contacts 58 extend outwardly into the cavity for engagement with the socket contacts 56 when the connector members are mated.
  • the mated contacts are disposed within the interior of the primary interfacial seal 30 and the secondary seal provided by the mating frusto-conical surfaces 20 and 38.
  • Means are integrally formed on the receptacle and plug connector members for retaining their respective contacts therein.
  • Such means comprises a flange 64 which extends radially inwardly from the wall of each contact passage. Said flange is sufficiently resilient and pliant to allow a contact to pass therethrough when it is inserted through the rear of the contact passage.
  • Each contact is formed with an annular recess 66. The depth of the recess 66 and the radial dimension of each flange 64 are such that the flange will have a snug fit in the recess to hold the contact against appreciable longitudinal movement relative to the connector mem her body.
  • a rear seal, generally designated 70, is provided between the rear portion of each contact passage in the connector members and the insulated wire 60 mounted therein.
  • such rear seal comprises a plurality of radially inwardly extending deformable ribs 72 which are integral with the wall of the passage. These ribs are dimensioned so as to have an interference fit with the insulation covering on the wire 60 thereby producing an intimate mechanical contact and labyrinth seal between the insulated wire and the connector member body.
  • the pressure acts on the wire insulation and body material causing the wire insulation to plastically deform and the body elastomer to elastically conform with increasing pressure. This results in a tight seal between the wire insulation and connector body.
  • the outer periphery of the ribs 34 and the inner periphery of the ribs 72 have a convexly curved configuration in longitudinal crosssection.
  • This configuration of the sealing ribs has been found to provide a far more effective sealing engagement than with ribs which have a flat outer or inner perimeter as the case may be.
  • the rear sections 74 of the receptacle and plug connector members are molded so as to have a reduced cross-section as best seen in FIG. 2.
  • the contact passages extend through the rear sections 74 of the connector body.
  • Each such secton is formed with three sides 76 disposed closely as possible to the walls of the passages to minimize the thickness of the body about the passages and thus provide a more resilient wall area around the passages for accommodating different size wires.
  • Longitudinally extending grooves 78 are formed in the walls 76 between the passages to further enhance the flexibility of the material surrounding the passages.
  • unitary connector members which have an interfacial seal, rear seals, latching arrangement and contact retention means all integrally formed thereon.
  • all the necessary features required for an effective connector are provided in a pair of unitary bodies of elastic pliant material. These bodies may be formed by conventional molding techniques. Therefore, it can be seen that the connector of the present invention may be manufactured at very low cost and with no assembly procedures required except the insertion of the contact terminated wires into the respective contact passages. Moreover, the latter procedure may be performed without the requirement of a special tool, and the contacts may be withdrawn from the connector members simply by pulling on the insulated wires, again without the requirement of a special tool for releasing the contact retention means.
  • a connector as illustrated in FIGS. 1 and 2 has been tested to determine its ability to withstand various temperatures and climatic conditions.
  • One sample of the connector was temperature cycled 100 times by subjecting it alternately to 40C for l hour followed by heating the connector to I05C for 1 hour.
  • the connector was immersed into water at the end of l l,l 8,80 and I00 cycles and was subjected to external pressurization of 10 psi. No leakage was evidenced at this pressure after this temperature cycling test. Also no electrical failure was observed.
  • Another sample of the connector was immersed in a 6 inch head of 57r salt solution at room temperature for 504 hours. No leakage was evidenced and satisfactory electrical resistance was maintained.
  • the mating surfaces 38 and 20 on the plug connector member annular section 26 and projection 18, respectively, have a cylindrical rather than a frusto conical configuration.
  • the forward inner surface of the annular section 26 is beveled to provide a frustoconical lead surface 80.
  • the outer surface of the projection 18 is also beveled to provide a frusto-conical lead surface 82 which is complementary to the surface 80.
  • the surfaces and 82 cooperate to facilitate insertion of the annular section 26 of the plug connector member into the recess 24 in the receptacle connector member.
  • FIG. 4 shows another embodiment of the invention wherein the interfacial seal 30 is in the form of a lip seal rather than a labyrinth seal.
  • the lip seal comprises a radially extending axially and radially resilient lip 84 integrally formed on the bottom of a recess 85 in the annular section 26 of the plug connector member. The length of this lip is greater than the distance between the bottom of the recess and the cylindrical surface 22 of the sleeve 16.
  • Sealing is effected by intimate mechanical contact and elastic deformation of the lip and the receptacle surfaces.
  • FIG. illustrates a connector having a lip seal 84 like that illustrated in FIG. 4. except that the lip seal is positioned forward of the flange 42 on the sleeve l6 when the connector members are mated.
  • FIG. 6 illustrates a modified form of a rear seal which may be utilized in the present invention.
  • the rear seal comprises an integral inwardly and rearwardly extending resilient lip 86 which terminates in a cylindrical radially expandable sleeve 88 concentrically disposed within the contact passage 52.
  • the sleeve 88 is dimen sioned to have an interference fit with the insulated wire 60 disposed in the passage.
  • the seal effectiveness increases with increasing external pressure acting on the external surface of the sleeve 88 and lip 86. It is noted that the lip 86 must extend rearwardly rather than forwardly inasmuch as with the latter increasing external pressure would overcome the elastic forces causing the seal to leak.
  • the contact 56 in the embodiment illustrated in FIG. 6 is shown as being an open barrel type contact.
  • FIG. 7 illustrates a modified form of a contact retention arrangement which may be utilized in the present invention.
  • a longitudinally extending radially resilient finger 90 is integrally formed with the wall of the contact passage 52.
  • a radially inwardly extending flange element 92 is formed on the end of the finger 90. This flange element extends into the contact recess 66 to limit axial movement of the contact within the passage 52. It will be appreciated that due to the resiliency of the finger 90, the flange element 92 will be forced radially outwardly when the contact 56 is in serted into or withdrawn from the passage 52.
  • interfacial and rear seals disclosed herein may be utilized in the connector of the present invention in any combination.
  • the rear lip seal illustrated in FIG. 6 could be used in place of the rear labyrinth seal in the connector illustrated in FIG. 1.
  • either of the interfacial lip seals illustrated in FIGS. 4 and 5 may be substituted for the interfacial labyrinth seal in the connector illustrated in FIG. I.
