Abstract

The present invention relates to a multiple tube connector (60). The multiple tube connector (60) includes two substantially identical first and second connector housings (62, 64). The first and second connector housings (62, 64) include an aperture (65) coaxially positioned therein. The aperture (65) includes a plurality of inwardly projecting, evenly spaced apart and substantially identical splines (88) defining key ways (90) therebetween. A locking spindle (66) is rotatably mounted in one of the first and second connector housings (62, 64). The locking spindle (66) includes evenly spaced apart, outwardly projecting and substantially identical splines (92) defining key ways (96) therebetween. The locking spindle (66) being rotatable between a released position wherein the splines (92) of the locking spindle (66) are aligned with the key ways (90) of the first and second connector housings (62, 64) such that the first and second connector housings (62, 64) can be placed in an abutting relationship and a locked position wherein the splines ( 92) of the locking spindle (66) are aligned with the splines (88) of the first and second connector housings (62, 64) such that the connector housings (62, 64) are locked in an abutting relationship.

Dependent claims

A multiple tube connector, comprising:

(a) a first cylindrical connector housing having an axially extending, outer rim portion interconnected to a transversely extending wall portion, the wall portion having an aperture substantially coaxial with respect to the rim portion, a plurality of apertures of lesser diameter than the coaxial aperture being disposed in the wall portion circumferentially about a major portion of the coaxial aperture, the coaxial aperture including a plurality of inwardly projecting, evenly spaced apart and substantially identical spline members, the spline members defining a plurality of axially extending keyways therebetween;
(b) a second cylindrical connector housing substantially identical to the first cylindrical connector housing;
(c) a plurality of axially extending hollow male and female inserts removably positioned in at least some of the apertures of lesser diameter, a first end of the female inserts being adapted to receive a first end of the corresponding male inserts when the first and second connector housings are placed in an abutting relationship, a second end of the male and female inserts being configured for insertion into a tube;
and
(d) a cylindrical locking spindle being rotatably retained proximate a first end in the first connector housing, the locking spindle defining proximate a second end a plurality of evenly spaced apart, outwardly projecting and substantially identical spline members, axially extending keyways being defined between the spline members, the locking spindle being interconnected by an elongated radially extending shaft to manually activated switch means for rotating the locking spindle between a first released position and a second locked position, the splines of the locking spindle cooperating with the key ways of the second connector housing to enable partial insertion of the locking spindle through the coaxial aperture of the second connector housing so as to place the first and second connector housings in an abutting relationship when in the first released position, the splines of the locking spindle cooperating with the splines of the second connector housing to lock the first and second connector housings together in an abutting relationship when in the second locked position, the rim portions of the first and second connector housings being cut away along a predetermined circumferential extent and the wall portions of the first and second connector housings being void of the apertures of lesser diameter along a corresponding extent to enable a predetermined amount of pivotal motion of the elongated shaft, the elongated shaft and the splines of the locking spindle cooperating with the first and second connector housings to provide a keying feature whereby proper matching of the respective male and female inserts is assured upon positioning of the first and second connector housings in an abutting relationship.

A multiple tube connector, comprising:

(a) a first connector housing having a plurality of apertures disposed therein;
(b) a second connector housing having a plurality of apertures disposed therein corresponding to the apertures of the first connector housing;
(c) male insert means and female insert means being removable positioned in corresponding ones of the apertures of the first and second connector housings for defining fluid flow paths for the flow of fluid through the first and second connector housings when the first and second connector housings are placed in an abutting relationship such that the male insert means are interconnected to corresponding ones of the female insert means, the first end of the female insert means being configured for interconnection to a first end of the male insert means, a second end of the male insert means and the female insert means being adapted for interconnection to an open end of a tube;
(d) locking spindle means of lesser diameter than the first connector housing and the second connector housing rotatably mounted in the first connector housing, the locking spindle means including spline and keyway means cooperating with spline and keyway means of the second connector housing for locking the first and second connector housings in an abutting relationship when the locking spindle means is in a locked position wherein corresponding ones of the male insert means and the female insert means are interconnected, and for allowing separation of the first and second connector housings when the locking spindle means is in a released position, the male insert means and the female insert means being positioned radially outwardly of the locking spindle means;
and
(e) switch means for rotating the locking spindle means between the locked position and the released position.

3 more elements

A multiple tube connector, comprising:

(a) a first connector housing including a plurality of male insert means for defining fluid flow paths through the first connector housing;
(b) a second connector housing including a plurality of female insert means corresponding to the male insert means, a first end of the female insert means including means for receiving a first end of the male insert means, a second end of the male insert means and the female insert means including means for interconnection to a tube;
(c) locking spindle means rotatably mounted in one of the first and second connector housings and including spline and keyway means of the other of the first and second connector housings for locking the first and second connector housings together when rotated to a locked position wherein corresponding ones of the male insert means and the female insert means are interconnected so as to provide fluid flow paths through the first and second connector housings and for allowing separation of the first and second connector housings when in a relased position, the locking spindle means further including keying means for assuring proper interconnection of the corresponding male insert means and female insert means, the male insert means and the female insert means being circumferentially disposed about the locking spindle means;
and
(d) switch means for rotating the locking spindle means between the locked position and the released position.
