Abstract
Abstract Fabricating techniques for forming insulated electrical connectors of the type to be subsequently mounted in panel apertures including techniques for simplifying the mold required to form such connectors and improvements in the connector itself and the manner in which that connector grips edges of an aperture in which it is mounted are disclosed. In its preferred form, the insulated electrical connector has a pair of generally flat parallel opposed side walls each provided with staggered notches oppositely extending from opposed side wall edges toward and slightly past one another in an overlapped and interleaved manner to form in the region of notch overlap a pair of slots extending generally parallel to one another and transverse to the notches.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
In a mold for forming insulating material about electrically conductive portions to form an electrical connector, the mold having a pair of mold cavity forming halves separable generally along at least one parting plane for removing formed electrical connectors from the mold, the improvement for forming a pair of generally parallel slots in opposed generally parallel sidewalls of such electrical connectors comprising a plurality of upstanding posts within the cavity halves immediately adjacent opposite connector sidewall forming cavity half sidewalls at least some of which extend beyond the parting plane and into the other cavity half when the halves are closed on one another, the posts of one cavity half directly contacting and overlapping the posts of the other mold half in an interleaved manner near the parting plane with the region of post overlap forming the connector slots.
Claim 2
Dependent Claim
139 words
In a mold for forming insulating material about electrically conductive portions to form an electrical connector, the mold having a pair of mold cavity forming halves separable generally along at least one parting plane for removing formed electrical connectors from the mold, the improvement for forming a pair of generally parallel slots in opposed generally parallel sidewalls of such electrical connectors comprising a plurality of upstanding posts within the cavity halves immediately adjacent opposite connector sidewall forming cavity half sidewalls at least some of which extend beyond the parting plane and into the other cavity half when the halves are closed on one another, the posts of one cavity half directly contacting and overlapping the posts of the other mold half in an interleaved manner near the parting plane with the region of post overlap forming the connector slots.
Claim 3
Dependent Claim
15 words
The improvement of claim 1 wherein each post is generally configured as a rectangular parallelepiped.
Claim 4
Dependent Claim
15 words
The improvement of claim 1 wherein each post extends along a cavity half side wall.
Claim 5
Dependent Claim
20 words
The improvement of claim 3 wherein one cavity half has four posts and the other cavity half has two posts.
Claim 6
Dependent Claim
119 words
In a mold for forming material into a grommet-like structure, the mold having a pair of mold cavity forming halves for forming at least a pair of open slots in sidewalls of the structure, the halves being separable for removing formed structures from the mold, the improvement comprising a plurality of upstanding posts within the cavity halves adjacent sidewalls thereof at least some of which extend into the other cavity half when the halves are closed on one another so that the posts of one cavity half directly contact and overlap the posts of the other cavity half in an interleaved manner with the region of post overlap effectively forming the open slots in the sidewall of the structure.
Claim 7
Dependent Claim
119 words
In a mold for forming material into a grommet-like structure, the mold having a pair of mold cavity forming halves for forming at least a pair of open slots in sidewalls of the structure, the halves being separable for removing formed structures from the mold, the improvement comprising a plurality of upstanding posts within the cavity halves adjacent sidewalls thereof at least some of which extend into the other cavity half when the halves are closed on one another so that the posts of one cavity half directly contact and overlap the posts of the other cavity half in an interleaved manner with the region of post overlap effectively forming the open slots in the sidewall of the structure.
Claim 8
Dependent Claim
15 words
The improvement of claim 5 wherein each post is generally configured as a rectangular parallelepiped.
Claim 9
Dependent Claim
20 words
The improvement of claim 5 wherein one cavity half has four posts and the other cavity half has two posts.
