The invention relates to a sealed connector assembly, particularly to a sealed electrical connector assembly suited for hand mating by a human assembly operator.
A connector assembly includes a female connector body, a male connector body defining a shroud configured to receive a forward portion of the female connector body, and a resilient seal axially surrounding the forward portion. The resilient seal is disposed intermediate the forward portion and the shroud and is in compressive contact with the forward portion and the shroud. The forward portion defines a forward retaining ledge on the forward portion. The forward retaining ledge extends inwardly from the forward portion. The resilient seal defines a forward retaining hook that extends outwardly and engages the forward retaining ledge.
In one embodiment, the connector assembly further includes a seal retainer that is attached to the female connector body. In this embodiment the resilient seal defines a seal lip that extends forward of the forward retaining hook. The seal lip is disposed intermediate the forward portion and the seal retainer and is in compressive contact with the forward portion and the seal retainer.
In one embodiment, a cavity is provided rearward of the resilient seal into which a rearward portion of the resilient seal can expand.
In one embodiment, the female connector body defines a retaining wall that circumferentially surrounds the forward portion and is configured to receive a portion of the shroud of the male connector body.
In one embodiment, the retaining ledge forms an acute angle relative to a longitudinal axis of the female connector body. In this embodiment, the retaining hook forms an obtuse angle relative to the longitudinal axis that is a supplementary angle to the acute angle.
In one embodiment, the seal lip and the forward retaining hook are formed integrally with the resilient seal.
In one embodiment, the resilient seal is asymmetrical about a lateral axis of the female connector body.
In one embodiment, the forward portion defines a rearward retaining ledge on a rearward end of the forward portion. The rearward retaining ledge extends outwardly from the forward portion. In this embodiment, the resilient seal defines a rearward retaining hook extending inwardly and engaging the rearward retaining ledge.
In one embodiment, the resilient seal is symmetrical about a lateral axis of the female connector body.
In one embodiment, the rearward retaining hook is formed integrally with the resilient seal.
The present invention will now be described, by way of example with reference to the accompanying drawings, in which:
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
Presented herein is a sealed electrical connector assembly that is suited for robustly, reliably, and safely carrying electrical currents greater than 200 amperes.
As illustrated in
As best shown in
A seal retainer 38 is attached to the female connector body 12 to retain the seal 22 in the proper position on the female connector body 12. The seal 22 defines a seal lip 40 that extends forward of the forward retaining hook 30. When the female connector body 12 is received within the shroud 16 of the male connector body 14, the seal lip 40 is disposed intermediate the forward portion 18 and the seal retainer 38 and is in compressive contact with the forward portion 18 and the seal retainer 38. The seal lip 40 is integrally formed with the seal 22.
As also best shown in
The female connector body 12 defines a retaining wall 44 circumferentially surrounding the forward portion 18 and configured to receive a portion of the shroud 16 of the male connector body 14.
The inventors have discovered that the seal 22 of the assembly does not the exhibit the pinching, bunching, and rolling seen in seals of prior art connector assembles which lack the retaining hook 30 and the cavity 42 rearward of the seal 22. Without subscribing to any particular theory of operation, the retention of the seal 22 by the forward retaining ledge 26 and forward retaining hook 30 and the cavity 42 rearward of the seal 22 cooperate to provide these benefits. The seal 22 also provides a lower engagement force between the seal 22 and the male connector body 14 and less sensitivity to seal gap than prior art seals as shown in Table 1 below. A reduction in engagement force also offers improved ergonomics for hand mating of the connector assembly by a human assembly operator.
While the example presented herein is directed to an electrical connector assembly, other embodiments may be envisioned that are adapted for use with other types of connector assemblies for fiber optic cables, pneumatic tubes, hydraulic tubes, or a hybrid connector assembly including two or more of the items listed above.
While this invention has been described in terms of the preferred embodiments thereof, it is not intended to be so limited, but rather only to the extent set forth in the claims that follow. For example, the above-described embodiments (and/or aspects thereof) may be used in combination with each other. In addition, many modifications may be made to configure a particular situation or material to the teachings of the invention without departing from its scope. Dimensions, types of materials, orientations of the various components, and the number and positions of the various components described herein are intended to define parameters of certain embodiments and are by no means limiting and are merely prototypical embodiments.
Many other embodiments and modifications within the spirit and scope of the claims will be apparent to those of skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference to the following claims, along with the full scope of equivalents to which such claims are entitled.
As used herein, ‘one or more’ includes a function being performed by one element, a function being performed by more than one element, e.g., in a distributed fashion, several functions being performed by one element, several functions being performed by several elements, or any combination of the above.
It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact.
The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
