Abstract

One embodiment of the present invention is a make-break connector for use, for example, with a heat exchanger, which make-break connector includes: (a) two or more connectors; and (b) a make-break mechanism affixed to one of the connectors.

Claims

1. A make-break connector that comprises:

two or more connectors, each of which two or more connectors is adapted to be connected at a first end to a first conduit and at a second end to a second conduit, wherein one of the connectors is a locking connector having an insertion channel therein with an insertion aperture;

a housing having a frontal portion that has;

(a) a front surface disposed in a front surface plane and (b) cutouts that support the connectors so that at least portions of front faces of the connectors are disposed in the front surface plane;

a make-break mechanism disposed in the housing that includes a button mechanism and a spring mechanism that biases the make-break mechanism so that at least a portion of the button mechanism extends through an aperture in the housing;

a latch structure that is affixed to the locking connector

wherein the latch structure includes a tab which tab is connected to the make-break mechanism so that;

(a) when the button mechanism is pushed, the latch structure is driven in a first direction, and (b) when the button mechanism is released, the spring mechanism urges the make-break mechanism so that the latch structure is driven in a second direction which is opposite the first direction;

wherein the latch structure has;

(a) an aperture whose shape and area is substantially the same as a shape and area of the insertion aperture, and (b) a slot; and

a pin that;

(a) rides in a pin channel in the locking connector, which pin channel disposed along a direction into and out of the locking connector, (b) is biased by a pin spring toward a front of the pin channel, (c) has a groove located a predetermined distance from an end of the pin;

whereby;

(a) when the latch structure is driven in the first direction, the pin is releases and the pin spring urges the pin so the groove extends beyond the slot;

(b) when the latch structure is driven in the second direction, the slot surrounds the pin outside the groove and the aperture in the latch structure and the aperture in the locking connector are coincident, allowing a male connecting extension of a mating connector to be inserted into the insertion channel, wherein the mating connector engages the pin as it extends beyond a front surface of the locking connector and urges the pin into the pin channel, and when the groove is lined up with the latch structure, the latch structure is able to move so the slot surrounds the pin at the groove, and so that an edge of the aperture in the latch sturcture inserted into a slot in the mating connector.

2. The make-break connector of claim 1 wherein one or more of the connectors is valved.

3. The make-break connector of claim 1 wherein the locking connector is unvalved.

4. The make-break connector of claim 1 wherein:

(a) the housing includes wells that are disposed behind the front surface of the frontal portion; and

(b) one or more magnets disposed in the wells so that a magnetic field extends from the one or more magnets a predetermined distance from the make-break connector.

5. The make-break connector of claim 4, wherein one magnet identifies a first type of apparatus is to be connected to the make-break connector and a larger number of magnets identifies that other types of apparatus are to be connected to the make-break connector.

6. The make-break connector of claim 4 wherein the one or more magnets are neodymium permanent magnets.

7. The make-break connector of claim 4 which further comprises a mating connector that includes a magnetic reed switch.

8. The make-break connector of claim 7 wherein the magnetic field sensing mechanism includes a magnetic reed switch.

9. The make-break connector of claim 1 wherein the two or more connectors comprise two connectors in addition to the locking connector and wherein a center of the two additional connectors that are spaced apart by a distance in a range from about 20 mm to about 60 mm.

10. The make-break connector of claim 9 wherein a center of the locking connector is disposed between the two additional connectors and is displaced in a direction that is perpendicular to a line joining the centers of the two additional connectors.

11. The make-break connector of claim 1 wherein:

(a) the cutouts are substantially in a shape of a periphery of front faces of the connectors;

(b) the cutout that supports the locking connector is configured so the locking connector is fixed in the front surface plane; and

(c) the cutouts that support the other connectors are configured so the other connectors can move within the front surface plane.

12. The make-break connector of claim 1 wherein:

(a) at least one of the connectors is a valved connector;

(b) the at least one of the connectors includes a male reception structure disposed and movable within a tube in the at least one of the connectors, which tube extends a predetermined distance from a front of the at least one of the connectors to a valve; and

(c) the male reception structure includes a front reception portion having an aperture and a spring mechanism that biases the male reception structure toward a front of the tube at a predetermined distance back from the front of the at least one of the connectors so that the male reception structure is pushed into the tube and the spring mechanism is compressed when a male connecting extension of a mating connector is inserted into the tube.

13. The make-break connector of claim 12 wherein the spring mechanism of the male reception structure has a sufficiently large spring coefficient so that the spring mechanism can drive the male reception structure toward the front of the valved connector so rapidly that the valve is opened for so short a time that there is substantially no leak.

14. The make-break connector of claim 12 wherein the male reception structure includes a leg structure extending into the tube from the front reception portion which is long enough so that when the leg structure is driven by insertion of the male connecting extension into the tube a back of the leg structure causes the valve to open;

and a depth of insertion of the male connecting extension is such that when the male connecting extension has been fully inserted into the valved connector, a front surface of the mating connector is substantially aligned against the front surface of the valved connector.

15. The make-break connector of claim 1 wherein one or more of the connectors includes a hose barb at the second end.

16. The make-break connector of claim 1 wherein each of the connectors is adapted to receive a male connecting extension of a mating connector.

17. The make-break connector of claim 1 wherein a profile of the frontal portion of the housing is recessed from a profile of a back portion of the housing to a depth sufficient to enable a sleeve portion of a mating connector to fit over the frontal portion whenever the mating connector is connected to the make-break connector.

18. The make-break connector of claim 1 wherein the frontal portion of the housing includes one or more indentations that serve as guides and/or support mechanisms for structure disposed in a sleeve portion of a mating connector.

19. The make-break connector of claim 1 wherein:

(a) a back portion of the housing has indented gripping sections;

(b) a rear area of the back portion of the housing is angled to a side, and the arc of the angle flows away from the indented gripping sections; and

(c) the housing has a recessed area which is located toward a front of the housing.

20. The make-break connector of claim 1 wherein:

(a) bosses are disposed in a front of a back portion of the housing and are disposed through apertures in the make-break mechanism so that the make-break mechanism can ride up and down the bosses; and

(b) the bosses support the spring mechanism that biases the make-break mechanism.

21. The make-break connector of claim 1 wherein the latch structure inserted into slots disposed in a frontal portion of the locking connector, which slots are disposed on either side of the insertion aperture of the locking connector.

22. The make-break connector of claim 1 wherein the tab is inserted into a slot in the make-break mechanism.

23. The make-break connector of claim 1 wherein a structure is disposed at a predetermined depth inside the locking connector to provide a stop for insertion of a male connecting extension of a male connector, and a depth of insertion of the male connecting extension is such that, when the male connecting extension is fully inserted into the locking connector, the mating connector substantially abuts a front surface of the locking connector.
