Abstract

Abstract A flexible connector includes a molded body of a soft material integrally molded with a connector body and connecting at least one cable, and locking screws passing through mounting lugs of the molded body and threadedly engaging internal threads of a mating device such as a receptacle. The connector comprises sleeves each fitted in the mounting lug and having an inner diameter larger than an outer diameter of a screw-threaded portion of the locking screw. Each sleeve is formed on its inside with at least one latch protrusion by calking at a location corresponding to a shank of the locking screw having an outer diameter less than the outer diameter of the screw-threaded portion so as to prevent the screw-threaded portion of the locking screw from passing through the sleeve, thereby reliably holding the locking screws in the mounting lug so as to prevent loosening and inadvertent removal of the locking screws, and positively connecting the connector to the receptacle without the possibility of undertightening of the locking screws and without any risk of damage of the mounting lugs.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 158 words
A flexible connector including a molded body of soft material integrally molded with a connector body, said molded body including at least one mounting lug in which a sleeve fitting aperture is formed, at least one locking screw associated with said molded body and threadedly engaging internal threads of a mating device such as a receptacle, said connector comprising, at least one sleeve having an inner diameter larger than the outer diameter of a screw-threaded portion of said locking screw and fitted in said sleeve fitting aperture, said sleeve including on its inner-facing surface at least one latch protrusion extending inwardly at a location corresponding to the shank of said locking screw having an outer diameter less than said outer diameter of said screw-threaded portion so as to prevent said screw-threaded portion of the locking screw from passing through the sleeve, said mounting lug including at least one hole formed therein for facilitating forming of the latch protrusion.
Claim 2
Dependent Claim 158 words
A flexible connector including a molded body of soft material integrally molded with a connector body, said molded body including at least one mounting lug in which a sleeve fitting aperture is formed, at least one locking screw associated with said molded body and threadedly engaging internal threads of a mating device such as a receptacle, said connector comprising, at least one sleeve having an inner diameter larger than the outer diameter of a screw-threaded portion of said locking screw and fitted in said sleeve fitting aperture, said sleeve including on its inner-facing surface at least one latch protrusion extending inwardly at a location corresponding to the shank of said locking screw having an outer diameter less than said outer diameter of said screw-threaded portion so as to prevent said screw-threaded portion of the locking screw from passing through the sleeve, said mounting lug including at least one hole formed therein for facilitating forming of the latch protrusion.
Claim 3
Dependent Claim 29 words
A connector as set forth in claim 1, wherein said hole for facilitating forming of the latch protrusion extends from a surface of the mounting lug to said sleeve.
Claim 4
Dependent Claim 31 words
A connector as set forth in claim 1, wherein said hole for facilitating forming of the latch protrusion extends from a surface of the lug and stops short of the sleeve.
Claim 5
Dependent Claim 25 words
A connector as set forth in claim 1, wherein the number of said mounting lugs is the same as the number of said locking screws.
Claim 6
Dependent Claim 36 words
A connector as set forth in claim 1, wherein said sleeve comprises small flanges at its ends for retaining it in the mounting lug and to form a seat for a head of the locking screw.
Claim 7
Dependent Claim 16 words
A connector as set forth in claim 1, wherein said latch protrusion is formed by calking.
Claim 8
Dependent Claim 23 words
A connector as set forth in claim 1, wherein said sleeve is formed with two latch protrusions in diametrical opposition to each other.
