Sealed electrical conductor assembly
First Claim
1. A sealed electrical connector assembly for use with electrical contacts attached to wires, the assembly including an electrical connector with a seal having apertures, extending through the seal, through which electrical contacts attached to wires pass when the electrical contacts are inserted into the electrical connector, the seal including sealing glands extending into each aperture, at least one aperture including a core seal gland for sealing around a wire extending therethrough,the electrical connector assembly being characterized by an ingress seal gland deformable during passage of an electrical contact through said aperture into a position between the corresponding core seal gland and the contact to prevent damage to the core seal gland by the contact.

Abstract
An electrical connector assembly 10 includes a seal 20 including sealing apertures 25 that including glands for sealing a wire extending through the aperture. A sealing unit 24 includes a lead in recess 26, a contact ingress seal gland 28, a core seal gland 30 and a contact egress seal gland 29. The core seal gland 30 establishes the primary seal with a wire extending through the seal, and the ingress seal gland 28 is deformable between the core seal gland 30 and the contact during contact insertion to protect the core seal gland 30 from damage. A pattern 40 of stress relieving recesses 42 et seq. surrounds the seal apertures, and include canted webs 43 et seq. The stress relieving recesses aid flexure of the seals and the seal glands. Other stress relieving recesses 56 located between seal apertures including perpendicular webs 57.

1. A sealed electrical connector assembly for use with electrical contacts attached to wires, the assembly including an electrical connector with a seal having apertures, extending through the seal, through which electrical contacts attached to wires pass when the electrical contacts are inserted into the electrical connector, the seal including sealing glands extending into each aperture, at least one aperture including a core seal gland for sealing around a wire extending therethrough,
the electrical connector assembly being characterized by an ingress seal gland deformable during passage of an electrical contact through said aperture into a position between the corresponding core seal gland and the contact to prevent damage to the core seal gland by the contact.

11. A sealed electrical conductor assembly for sealingly receiving an electrical contact terminated to an electrical conductor, said sealed assembly comprising:
-
(a) a seal having a seal surface;
(b) a contact receiving aperture extending into the seal from the seal surface for receiving said contact and said conductor therethrough;
(c) a lead-in recess formed on said seal surface adjacent said contact receiving aperture for receiving said contact;
(d) said contact receiving aperture comprises a plurality of sealing glands including an ingress gland and a core gland;
(e) whereby as said contact is inserted into said contact receiving aperture, said contact is operative to push said ingress gland into engagement with said core gland, whereby said ingress gland is interposed between said core gland and a corner area of said contact, said ingress gland thereby protecting said core gland from tearing as said contact is inserted through said seal. - View Dependent Claims (12, 13)

- 14. A seal for use is sealing wires entering an electrical connector, the seal having a plurality of apertures alignable with cavities in the electrical connector in which electrical contacts are positioned, the electrical contacts being insertable through the seal apertures into the cavities, the seal including sealing glands in each aperture to seal wires extending through the aperture, the seal also including stress relieving recesses adjacent to the apertures, coaxial stress relieving recesses extending inwardly from opposite faces of the seal and being separated by webs located between the opposite faces of the seal, the stress relieving recesses permitting deformation of the seals as the electrical contacts are inserted through the apertures to reduce damage to sealing glands by the electrical contacts.

22. A seal for an electrical connector, comprising an member having a contact receiving aperture with a plurality of sealing glands therethrough, a lead-in recess being formed along an exterior surface of the contact receiving aperture, a frangible gland being disposed adjacent to the exterior surface along the lead-in recess, whereby as an electrical contact is received through the contact receiving aperture, the frangible gland stretches over a forward surface of the contact and protects the sealing glands from engaging the contact and thereby ripping or tearing.
-
23. A seal for an electrical connector, the electrical connector having a plurality of electrical contacts terminated to a plurality of conductors, the seal providing a sealing relationship around the conductors, the seal having a plurality of contact receiving apertures through which the conductors will be received, the seal having a conductor engaging gland along the contact receiving aperture, the contact receiving aperture having a frangible gland along an exterior surface of the aperture, whereby as an electrical contact is received through the contact receiving aperture, the frangible gland stretches over a forward surface of the contact and protects the conductor engaging gland from engagement with the contact and thereby ripping or tearing.
