Abstract

Abstract The invention is an improvement to the female portion of a quick disconnectlectrical connector so that said portion can be easily disassembled for refurbishment. The female portion of the quick disconnect is of the type having concentric sleeves which are slidable with respect to one another. The forward ends of the sleeves are adapted to receive a male portion of the mating electrical connector, and the rearward end of one of the sleeves is connected to an elongated element, such as an electrical cable. An annular space is provided at the rearward end portions of an inner and outer adjacent pair of the sleeves, and a compression spring within the annular space is utilized for urging the adjacent sleeves longitudinally apart with respect to one another. The improvement includes a device located within a rear portion of the annular space and releasably connected to the inner adjacent sleeve for stopping rearward movement of the compression spring. The improvement further includes a device located within a forward portion of the annular space and releasably connected to the outer adjacent sleeve for stopping forward movement of the compression spring. With this arrangement the outer sleeve can be slid forwardly and removed entirely from the inner sleeve after release and removal of the stop devices.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 262 words
In the female portion of a quick disconnect of the type having inner, outer, and middle concentric sleeves which are all slidable with respect to one another, the forward ends of the sleeves being adapted to receive a male portion of the quick disconnect, the rearward end of the middle sleeve being connected to an elongated element, the middle sleeve having a rearwardly reduced diameter to provide an annular space between the middle and outer sleeves, a compression spring within said annular space for urging the outer sleeve forwardly with respect to the middle sleeve, the outer sleeve being counterbored at a forward end to receive balls which are radially slidable in apertures in the middle sleeve, the middle sleeve being counterbored to receive a spring means for urging the inner sleeve forwardly to open and close said apertures and thereby drop the balls inwardly and release the outer sleeve from the middle sleeve when the inner sleeve is pushed rearwardly, the improvement comprising: means located within a rear portion of said annular space and releasably connected to the middle sleeve for stopping rearward movement of the compression spring; means located within a forward portion of the annular space and releasably connected to the outer sleeve for stopping forward movement of the compression spring; and both stop means being removable rearwardly from the annular space when released from their respective sleeves, whereby, after release and removal of the stop means, the outer sleeve can be slid forwardly and removed entirely from the middle and inner sleeves without interference by said elongated element.
Claim 2
Dependent Claim 262 words
In the female portion of a quick disconnect of the type having inner, outer, and middle concentric sleeves which are all slidable with respect to one another, the forward ends of the sleeves being adapted to receive a male portion of the quick disconnect, the rearward end of the middle sleeve being connected to an elongated element, the middle sleeve having a rearwardly reduced diameter to provide an annular space between the middle and outer sleeves, a compression spring within said annular space for urging the outer sleeve forwardly with respect to the middle sleeve, the outer sleeve being counterbored at a forward end to receive balls which are radially slidable in apertures in the middle sleeve, the middle sleeve being counterbored to receive a spring means for urging the inner sleeve forwardly to open and close said apertures and thereby drop the balls inwardly and release the outer sleeve from the middle sleeve when the inner sleeve is pushed rearwardly, the improvement comprising: means located within a rear portion of said annular space and releasably connected to the middle sleeve for stopping rearward movement of the compression spring; means located within a forward portion of the annular space and releasably connected to the outer sleeve for stopping forward movement of the compression spring; and both stop means being removable rearwardly from the annular space when released from their respective sleeves, whereby, after release and removal of the stop means, the outer sleeve can be slid forwardly and removed entirely from the middle and inner sleeves without interference by said elongated element.
Claim 3
Dependent Claim 32 words
The improvement as claimed in claim 1 including: the forward stop means being an internal retainer ring; and the annular space being wide enough for rearwardly removal of the internal retainer ring.
Claim 4
Dependent Claim 23 words
An improvement as claimed in claim 2 including: the quick disconnect being an electrical disconnect; and the elongated element being an electrical cable.
Claim 5
Dependent Claim 170 words
In the female portion of a quick disconnect of the type having concentric sleeves which are slidable with respect to one another, the forward ends of the sleeves being adapted to receive a male portion of the quick disconnect, the rearward end of one of the sleeves being connected to an elongated element, an annular space provided at the rearward end portions of an inner and outer adjacent pair of the sleeves, and a compression spring within the annular space for urging the adjacent sleeves longitudinally with respect to one another, the improvement comprising: means located within a rear portion of said annular space and releasably connected to the inner adjacent sleeve for stopping rearward movement of the compression spring; and means located within a forward portion of the annular space and releasably connected to the outer adjacent sleeve for stopping forward movement of the compression spring whereby, after release and removal of the stop means, the outer sleeve can be slid forwardly and removed entirely from the inner sleeve.
Claim 6
Dependent Claim 170 words
In the female portion of a quick disconnect of the type having concentric sleeves which are slidable with respect to one another, the forward ends of the sleeves being adapted to receive a male portion of the quick disconnect, the rearward end of one of the sleeves being connected to an elongated element, an annular space provided at the rearward end portions of an inner and outer adjacent pair of the sleeves, and a compression spring within the annular space for urging the adjacent sleeves longitudinally with respect to one another, the improvement comprising: means located within a rear portion of said annular space and releasably connected to the inner adjacent sleeve for stopping rearward movement of the compression spring; and means located within a forward portion of the annular space and releasably connected to the outer adjacent sleeve for stopping forward movement of the compression spring whereby, after release and removal of the stop means, the outer sleeve can be slid forwardly and removed entirely from the inner sleeve.
Claim 7
Dependent Claim 46 words
The improvement as claimed in claim 4 including: the quick disconnect being an electrical disconnect; the elongated element being an electrical cable; the forward stop means being an internal retainer ring; and the annular space being wide enough for rearwardly removal of the internal retainer ring.
