This invention relates generally to sealed electrical 1n connector~ and more particularly to an interface sealing arrangement for mating electrical connector bodies.
Electrical systems of automotive vehicles, particu-larly passenger cars, are becoming increasingly complex and sophisticated. This in turn results in increased usage of low current subsystems which, in some instances, require low current electrical connectors in a location exposed to weather conditions, such as at the vehicle underbody. ~or proper functioning, a low current electrical connector must be kept free of contaminants, particularly water and moisture. Yet at such a location, the connector is subjected to road splash, snow accumulation and other harmful weather effects.
The object of this invention is to provide an inter-face sealing arrangement for matable electrical connector bodies which protects internal electrical connections from weather co~ditions expected during operation of an automotive vehicle.
Another object of this invention is to provide a satisfactory interface sealing arrangement for matable electrical connector bodies which have internal low current electrical connections and which are exposed to weather conditions which subject the connector bodies to moisture and water.
" 1138~73 Yet another object of this invention is to provide a satisfactory interface sealing arrangement for matable con-nector bodies which house low current electrical connections and which are located at the underbody of an automotive vehicle~
Still another object of this invention i8 to provide an interfac0 sealing arrangement for mating electrical connector bodies which is substantially waterproof and moi~ture proof when subjected to weather conditions expected during operation of an automotive vehicle.
A ~eature of the invention is that the interface sealing arrangement incorporates a long barrier path guarding against entry of water and moisture without substantially increasing the overall length of the connector bodies.
Another ~eature of the invention i8 that the inter-face sealing arrangement also serves as a guide for mating the terminals carried in the respective electrical connector bodies.

~igure 1 is a longitudinal section of a sealed electrical connector having an interface ~ealing arranqement
-2-~38~73 in accordance with this in~-ention;
Figure 2 is a sectlon taken substantially alsng the line 2-2 of Figure 1 looking in the direction of the arrows;
Figure 3 is a section taken sub~tantially along the line 3-3 of Figure 1 looking in the direction of the arrows;
Figure 4 is a section taken sub~tantially along the line 4-4 of Figure 1 looking in the direction of the arrows:
Fiyure 5 is a section taken sub~tantially along the line 5-5 of Figure 1 looking in the direction of the arrows;
and Figure 6 is an exploded perspective view of the electrical connector shown in Figure 1.
Referring now to the drawing and particularly Figure 1, there is disclosed a sealed electrical connector 10 comprising a plug connector body 12 and a socket connector body 14 each made of a molded dielectric plastic material such as nylon.
The plug connector body 12 has a pair of longitudinal cavities 16 extending through the plug connector body. Each cavity 16 has an enlarged rearward portion 18 of circular outline which is open at the rear of the plug connector body 12 for assembly of a female terminal 20 attached to an insulated lead wire 22.
l'he forward portion 24 of each of the cavities 16 i~
defined by one 4f a pair of laterally spaced longitudinal towers 26 at the forward end of the plug connector body 12.
~ach forward cavity portion 24 has a chamfered opening at the forward end of its associated tower 26 and pilot means com-prising four forward diagonal pads 28 and a rearward annular rib 29 which also serves as a latch shoulder.
~he female terminal 20 comprises a forward elongated ~3~
socket 30 in the form of a split tube which is located in the forward cavity portion 24. The elongated socket 30 is piloted on the diagonal pads 28 and the annular rib 29 and it includes a pair of diametrically opposed latch tangs which cooperate with the rib 29 to retain the female terminal 20 in the cavity 16.
The rearward portion of the female terminal 20 has stop wings 31 and an attachment portion 32. The attachment portion 32 attaches a multiple lip cable seal 34, the lead wire 22 and the female terminal 20 together.
The plug connector body 12 has a hinged flap 36 which is movable to a closed latched position after a female terminal 20 is inserted into each of the cavities 16. In its closed position, the flap 36 cooperates with -the cable seals 34 to retain the female terminals 20 in their respective cavities in the event that the terminal latch tangs are damaged.
The plug connector body ]2 also has an ex-ternal latch projection 38 for locking the socketconnector body 14 in a mated position.
The socket connector body 14 has a pair of longitudinal cavities 40 which extend through the socket connector body to provide openings at each end. Each of the cavities 40 has a forward enlarged portion 42, an intermediate reduced portion 44 and an enlarged rearward portion 46. The rearward portion 46 is of circular outline and sized to sealingly engage a cahle seal 48 at-tached to a lead wire 50 by a male terminal ~/ ,, ...~
~3~ 3 52 in the same manner as the female terminal 20.
The male terminal 52 has an intermediate split barrel portion which in this instance is supported on pilot means in the intermediate cavity portion 44 comprisiny four diagonal pads 54 and a rearward annular shoulder 56. The male terminal 52 further comprises an elongated contact 58 at its forward end which fits in the elongated socket 30 of the female terminal 20 in a biased engagement.
The male terminal 52 is retained in the cavity 40 by lock tangs engaging the annular shoulder 56. Substantially the entire elongated contact 58 is located in the enlarged forward cavity portion 42 in a central position spaced radially from the side wall 60 of the enlargedcavity portion 42 which slidably receives an associated tower 26 of the plug connector body 12. The tip of the elong~ted contact 58 is preferably spaced rearwardly of the forward end of the enlarged cavity portion 42 so that the associa-ted tower 26 initially engages the side wall 60 to guide the socket 30 into engagement with the elongated contact 58.
The sliding fit of the towers 26 in the side wall 60 of the enlarged cavity portions 42 forms part of an interface sealing arrangement which further cornprises a longitudinal.ly projecting shroud 62 at the forward end of socket connector ;~~'' :~L13~
body 14 and a seal pad 64. The shroud 62 surroundx the rear-ward e~d portion~ of the towex~ 26 and provides an internal peripheral sealing surface 66 which is forward of and spaced radially outwardly of the enlarged cavity portions 42O The seal pad 64 is made from an elastomeric material. It has a pair of longitudinal apertures 68 extending through its body by means of which the seal pad 64 is mounted on the towers 26.
These aperture3 68 are slightly undersized with respect to the rearward end portion~ of the towers 26 to effect a good seal at the tower surfaces when mounted in the position shown in Figure 1. The seal pad 64 also has a plurality of flexible radial sealing lips 70 which are deformed into sealing engage-ment with the sealing surface 66 of the shroud 62 when the connector bodie~ 12 and 14 are mated.
The seal pad 64 provides the primary barrier against water and moisture entering the cavities 16 and 40 via the interface of the mated connector bodies 12 and 14. The radial spacing of the sealing surface 66 outwardly of the forward enlarged cavity portions 42 i8 a second barrier and the sliding fit between the towers 26 and the enlarged cavity portions 4Z
iR yet a third barrier.
The effectiveness of the interface sealing arrange-ment is enhanced by making the overlap of the mated connector bodies 12 and 14 in the longitudinal direction as long as possible. This is accomplished by placing nearly all of the elongated ~ockets 30 of the female terminals 20 in ~heir respective towers 26 and substantially the entire elongated contacts 58 of the male termi;nal~ 52 into the enlarged cavity portions 42.
While the interface sealing arrangement has been ~hown in connection with a two-way connector, the arrangement ~L~38~73 is applicable to other mul ~iple connectors (three-~ay~ four-way, etc.) and even one-way connector~. The sealing arrange-ment, however, i5 especially suitable for multiple connectors ~two-way, three-way, four-way, etc.) for low current applica-tions to avoid arcing or the bridging of adjacent sets of mated terminals by water or moisture.
Multiple connectors may employ an indexing means to insure mating of the bodies in the proper orientation. In the two-way connector shown in the drawing, this indexing means takes the form of a longitudinal slot 72 in one of he towers 26 and a mating longitudinal rib 74 in the enlarged cavity portion 42 which it slides into when the connector bodies are mated.
The socket connector body 14 also has a hinged flap 76 which is movable to closed latched position to provide a secondary lock for the male terminals 52 and a resilient latch arm 78 which cooperates with the latch projection 38 to lock the connector bodies 12 and 14 in the mated position. These are more or les~ standard features which, per se, do not ~orm a part of this invention which as indicated above is directed to the interface sealing arrangement for the connector bodies 12 and 14.
We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
