CONNECTORS

Abstract

A connection apparatus suitable for mounting on a structural element and connection to a port of a system or component in which the connection apparatus comprises a connector, a flange and a compressible biasing means is provided. The connector forms a longitudinally extending conduit having an axis (A) extending along the centre of the conduit, a port end adapted to be engaged with the port of a system or component, and a second end. The connector comprises a shoulder extending around the perimeter of the connector, and the shoulder extends around the perimeter of the connector in a direction substantially perpendicular to the portion of the conduit axis (as) around which the shoulder extends. The biasing means is adapted to at least partially extend around a portion of the connector adjacent to the shoulder.

DETAILED DESCRIPTION

[0053] With reference to FIG. 1, a connection apparatus 2 is connected to a conduit 6 and a system or component 4. The connection apparatus 2 is connected to the system 4 via a system port 10 and suitable connection means 30 (shown in FIG. 2). The system port 10 is the end of one or more system conduits (not shown) located within the system 4. In the embodiment shown in FIG. 1, the system 4 may be a hydraulic pump and the system conduits, connection apparatus 2 and conduit 6 are all part of a hydraulic system. In other embodiments the system 4 has other functions and/or constructions.

[0054] With reference to FIGS. 2 to 4, the connection apparatus 2 comprises connector 14, a flange 12 and a compressible biasing means 16.

[0055] The connector 14 comprises a connection leg 18 and a connection arm 20 with an elbow 22 between and connecting the connection leg 18 and the connection arm 20. The connector 14 defines a substantially tubular void or conduit that extends along the connector 14 and has a port end 26 and a second end 28. A conduit axis A extends along the geometric centre of the conduit. The connector 14 has a circular or approximately circular cross-section in the plane perpendicular to the conduit axis A along the connection leg 18 and connection arm 20.

[0056] A shoulder 26 extends around a portion of the connector leg 18 in a radially outward and circumferential fashion. The shoulder 26 has first and second faces 32, 34 which are facing in an axial direction (in relation to the portion AS of conduit axis A around which shoulder 24 extends). The first and second shoulder faces 32, 34 are substantially parallel to each other.

[0057] Extending between the first and second shoulder faces 32, 34 is a circumferential face 36. A circumferential groove 38 houses a seal 40, for example an O-ring.

[0058] The flange 12 is a split flange comprised of first and second flange elements 12A, 12B. The flange elements 12A, 12B include a number of apertures 42 through which bolts 44 may extend. The first and second flange elements 12A, 12B are each configured to define half of an aperture 46A, 46B through which the portion of the connection leg 18 adjacent the shoulder face 34 may extend. The aperture 46A, 46B may be so dimensioned that the first and second flange elements 12A, 12B are in sliding contact with the contact leg 18 (as shown in FIG. 3), or may be spaced from the contact leg 18.

[0059] The biasing means 16 is a single turn wave spring. In other embodiments the biasing means 16 may be a helical compression spring, a multi-turn wave spring or a nested wave spring.

[0060] With reference to FIGS. 3 to 6, a connection system according to the present disclosure comprises the connection apparatus as described in connection with FIGS. 2 to 4 above, and a structural element 8.

[0061] With reference to FIGS. 5 and 6, the structural element 8 defines an aperture 48, a first recess 52, and a second recess 56.

[0062] The second recess 56 is a recess in the surface 62 of the structural element 8. The second recess 56 is defined by a second recess wall 58 and a second recess base 60. The second recess base 60 is substantially parallel to the surface 62 of the structural element 8 adjacent the second recess 56.

[0063] The second recess 56 is so dimensioned that the flange 12A, 12B can be received into the second recess 56 (as shown in FIGS. 3 and 4). Extending into the structural element 8 through the second recess base 60 are the same number of threaded bores 64 as there are apertures 42 in the first and second flange elements 12A, 12B. The threaded bores 64 are adapted to engage with the bolts 44 which pass through the apertures 42 to fix the flange 12 in the fixed position (shown in FIGS. 3 and 4).

[0064] Also extending into the structural element 8 through the second recess base 60 is the first recess 50. The first recess 50 is defined by a first recess wall 52 and a first recess base 54. The first recess base 54 is substantially parallel to the surface 62 of the structural element 8 adjacent the second recess 56.

[0065] The first recess 50 is so dimensioned that the shoulder 24 and biasing means 16 can be received into the first recess 50 (as shown in FIGS. 3 and 4). The first recess 50 may be so dimensioned that the shoulder 24 is in sliding contact with the first recess wall 52 (as shown in FIGS. 3 and 4). Alternatively, the shoulder 24 may be spaced from the first recess wall 52 to allow a degree of lateral movement of the connector 14 relative to the structural element 8.

[0066] Extending into the structural element 8 through the first recess base 54 is the aperture 48. The aperture 48 is defined by an aperture wall 66 and so dimensioned that the portion of the connection leg 18 between the shoulder 24 and second end 28 can pass through the aperture 48. The aperture 48 may be so dimensioned that the connection leg 18 is spaced from the aperture wall 66 (as shown in FIGS. 3 and 4).

[0067] The intersection of the aperture wall 66 and the first recess base 54 is spaced from the first recess wall 52. The portion of the recess bass 54 between the aperture wall 66 and the first recess wall 52 is of sufficient dimensions for the biasing means 16 to bare against the first recess wall 52 when the flange 12 is in the fixed position.

[0068] With reference to FIGS. 7 to 10, the orientation of the connection arm 20 of the connection system may be altered as required once the biasing means 16 and connector 14, in particular the shoulder 24, are trapped in the structural element 8 by the flange 12 as shown in FIG. 7. The biasing means 16 is partially compressed and is forcing the shoulder against the face 74 of the flange 12.

[0069] To reorient or realign the connection arm a user applies force to the connector 14 in the direction of the arrow 68. That force causes the biasing means 16 to further compress and the shoulder 24 to move away from the face 74 of the flange 12 to create a space 72 as shown in FIG. 8. The user then applies a rotational force shown by arrow 70 to the connector 14. The rotational force causes the connector 14 to rotate around the portion AS of the conduit axis A. this causes the connection arm 20 to become orientated as shown in FIG. 9.

[0070] The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made to the embodiments described without departing from the scope of the invention disclosed. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in light of a review of this disclosure.

[0071] Various aspects of the connection system and connection apparatus disclosed in the embodiment may be used alone, in combination, or in a variety of arrangements not specifically discussed in the embodiment described above. This disclosure is therefore not limited in its application to the details and arrangement of components set forth in the foregoing description or illustrated in the drawings. Although a particular embodiment has been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects. The scope of the following claims should not be limited by the embodiments set forth in the example, but should be given the broadest reasonable interpretation consistent with the description as a whole.
