Description
- This application is a continuation of U.S. patent application Ser. No. 15/784,129, filed Oct. 14, 2017, entitled “Connector Assemblies for Connecting Tubulars and Related Methods, which claims priority to U.S. Provisional Patent Application No. 62/408,527, filed Oct. 14, 2016, each which is incorporated herein by reference in its entirety.
- The present invention relates generally to connector assemblies for connecting tubulars (e.g., tubes, pipes, lines, conduits, hoses, and/or the like), and more specifically, but not by way of limitation, to connector assemblies for connecting oil and/or gas well-related tubulars, such as, for example, risers, pipes (e.g., drill, casing, pipeline, and/or the like pipes), lines (e.g., choke, kill, and/or the like lines), and/or the like, to other oil and/or gas well-related tubulars and/or to oil and/or gas well-related structures.
- Tubular connectors, which are used in a variety of industries, allow for the connection of tubulars to other tubulars and/or to structures. As one example, in the oil and gas industry, tubular connectors are often used to connect sections of a tubular (e.g., a riser, drill pipe, and/or the like) when lowering the tubular toward a well.
- Some tubular connectors, such as traditional drill pipe connectors and casing connectors, are threaded. To connect a tubular to such a threaded connector, a thread of the connector is engaged with a corresponding thread of the tubular, and the tubular is rotated relative to the connector. Connecting tubulars using such threaded connectors may be problematic and/or time consuming, as such a threaded connector may be unforgiving of misalignment between a tubular and the connector, require multiple rotations of the tubular relative to the connector, and/or the like.
- Some tubular connectors, such as traditional riser connectors, include flanges through which fasteners (e.g., bolts) can be disposed in order to connect tubulars to other tubulars and/or to structures. In addition to such flange-based connectors being unforgiving of tubular/connector misalignment, connecting tubulars using such flange-based connectors may—at least by involving the use of separate fasteners—be undesirably complex and/or time consuming.
- Some embodiments of the present connector assemblies for connecting a first tubular to a second tubular comprise: a female connector having a sidewall extending between a first end and a second end to define an interior channel, the sidewall having a cylindrical inner surface, the second end configured to be coupled to the first tubular, and a plurality of lugs extending from and disposed circumferentially along the inner surface, and a male connector having a sidewall extending between a first end and a second end to define an interior channel, the sidewall having a cylindrical outer surface, the second end configured to be coupled to the second tubular, and a plurality of lugs extending from and disposed circumferentially along the outer surface, wherein the male connector is configured to be coupled to the female connector such that the sidewall of the male connector is at least partially received within the interior channel of the female connector, and at least one of the lugs of the male connector is disposed between at least one of the lugs of the female connector and the second end of the female connector and in contact with the at least one lug of the female connector.
- In some connector assemblies, the male connector is configured to be coupled to the female connector such that each of the lugs of the male connector is disposed between at least one of the lugs of the female connector and the second end of the female connector and in contact with the at least one lug of the female connector. In some connector assemblies, the male connector is configured to be coupled to the female connector such that each of the lugs of the female connector is disposed between at least one of the lugs of the male connector and the second end of the male connector and in contact with the at least one lug of the male connector.
- In some connector assemblies, the male connector is configured to be coupled to the female connector at least by inserting the first end of the male connector through the first end of the female connector and into the interior channel of the female connector such that at least one of the lugs of the male connector extends longitudinally beyond at least one of the lugs of the female connector, and rotating the male connector relative to the female connector such that the at least one lug of the male connector is disposed between the at least one lug of the female connector and the second end of the female connector and in contact with the at least one lug of the female connector.
- In some connector assemblies, for the female connector, the lugs extend along the inner surface of the sidewall a collective circumferential distance that is approximately 75% of a circumference of the inner surface. In some connector assemblies, for the male connector, the lugs extend along the outer surface of the sidewall a collective circumferential distance that is approximately 75% of a circumference of the outer surface. In some connector assemblies, circumferentially adjacent ones of the lugs of at least one of the female connector and the male connector are longitudinally offset relative to one another.
- In some connector assemblies, for at least one of the female connector and the male connector, a thickness of at least one of the lugs decreases along the lug in a direction from the second end and toward the first end. In some connector assemblies, at least one of the lugs of the female connector has a width, measured along a circumference of the inner surface, and a length, measured in a direction aligned with a longitudinal axis of the female connector, that is smaller than the width. In some connector assemblies, at least one of the lugs of the male connector has a width, measured along a circumference of the outer surface, and a length, measured in a direction aligned with a longitudinal axis of the male connector, that is smaller than the width.
- In some connector assemblies, at least one of the lugs of the female connector includes a mating surface configured to contact at least one of the lugs of the male connector when the male connector is coupled to the female connector, and the mating surface is angularly disposed at a non-perpendicular angle relative to a plane that is perpendicular to a longitudinal axis of the female connector. In some connector assemblies, at least one of the lugs of the male connector includes a mating surface configured to contact at least one of the lugs of the female connector when the male connector is coupled to the female connector, and the mating surface is angularly disposed at a non-perpendicular angle relative to a plane that is perpendicular to a longitudinal axis of the male connector.
- In some connector assemblies, the sidewall of the female connector tapers in thickness at the first end. In some connector assemblies, the sidewall of the male connector tapers in thickness at the first end. In some connector assemblies, the female connector includes a ramp extending from the inner surface of the sidewall, the ramp configured to contact the first end of the male connector when the male connector is coupled to the female connector.
- Some connector assemblies comprise a locking member having one or more tabs, wherein the locking member is configured to be coupled to the female connector or the male connector such that, when the male connector is coupled to the female connector, each of the one or more tabs contacts at least one of the lugs of the female connector and/or at least one of the lugs of the male connector. In some connector assemblies, the female connector or the male connector defines one or more openings configured to receive the one or more tabs of the locking member.
- In some connector assemblies, the female connector is coupled to the first tubular and/or the male connector is coupled to the second tubular. In some connector assemblies, the first tubular and the second tubular each comprise a riser or a drill pipe.
- Some embodiments of the present methods for connecting a first tubular to a second tubular comprise coupling a male connector to a female connector, wherein the female connector comprises a sidewall extending between a first end and a second end to define an interior channel, the sidewall having a cylindrical inner surface, the second end coupled to a first tubular, and a plurality of first lugs extending from and disposed circumferentially along the inner surface, wherein the male connector comprises a sidewall extending between a first end and a second end to define an interior channel, the sidewall having a cylindrical outer surface, the second end coupled to a first tubular, and a plurality of first lugs extending from and disposed circumferentially along the outer surface, and wherein the coupling the male connector to the female connector comprises inserting the first end of the male connector through the first end of the female connector and at least partially into the interior channel of the female connector such that at least one of the first lugs of the male connector extends longitudinally beyond at least one of the first lugs of the female connector, and rotating the male connector relative to the female connector such that the at least one first lug of the male connector is disposed between the at least one first lug of the female connector and the second end of the female connector and in contact with the at least one first lug of the female connector.
- In some methods, the male connector comprises a plurality of second lugs extending from and disposed circumferentially along the outer surface, the second lugs being circumferentially and longitudinally offset relative to the first lugs of the male connector, and the coupling the male connector to the female connector comprises further inserting the male connector into the female connector such that at least one of the second lugs of the male connector extends longitudinally beyond at least one of the first lugs of the female connector, and further rotating the male connector relative to the female connector such that the at least one second lug of the male connector is disposed between the at least one first lug of the female connector and the second end of the female connector and in contact with the at least one first lug of the female connector. In some methods, the female connector comprises a plurality of second lugs extending from and disposed circumferentially along the inner surface, the second lugs being circumferentially and longitudinally offset relative to the first lugs of the female connector, the further inserting is performed such that at least one of the first lugs of the male connector extends longitudinally beyond at least one of the second lugs of the female connector, and the further rotating is performed such that the at least one first lug of the male connector is disposed between the at least one second lug of the female connector and the second end of the female connector and in contact with the at least on second lug of the female connector.
- The term “coupled” is defined as connected, although not necessarily directly, and not necessarily mechanically; two items that are “coupled” may be unitary with each other. The terms “a” and “an” are defined as one or more unless this disclosure explicitly requires otherwise. The term “substantially” is defined as largely but not necessarily wholly what is specified (and includes what is specified; e.g., substantially 90 degrees includes 90 degrees and substantially parallel includes parallel), as understood by a person of ordinary skill in the art. In any disclosed embodiment, the terms “substantially” and “approximately” may be substituted with “within [a percentage] of” what is specified, where the percentage includes 0.1, 1, 5, and 10 percent.
- The phrase “and/or” means and or or. To illustrate, A, B, and/or C includes: A alone, B alone, C alone, a combination of A and B, a combination of A and C, a combination of B and C, or a combination of A, B, and C. In other words, “and/or” operates as an inclusive or.
- Further, a device or system that is configured in a certain way is configured in at least that way, but it can also be configured in other ways than those specifically described.
- The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), and “include” (and any form of include, such as “includes” and “including”) are open-ended linking verbs. As a result, an apparatus that “comprises,” “has,” or “includes” one or more elements possesses those one or more elements, but is not limited to possessing only those one or more elements. Likewise, a method that “comprises,” “has,” or “includes” one or more steps possesses those one or more steps, but is not limited to possessing only those one or more steps.
- Any embodiment of any of the apparatuses, systems, and methods can consist of or consist essentially of—rather than comprise/have/include—any of the described steps, elements, and/or features. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.
- The feature or features of one embodiment may be applied to other embodiments, even though not described or illustrated, unless expressly prohibited by this disclosure or the nature of the embodiments.
- Some details associated with the embodiments are described above, and others are described below.
- The following drawings illustrate by way of example and not limitation. For the sake of brevity and clarity, every feature of a given structure is not always labeled in every figure in which that structure appears. Identical reference numbers do not necessarily indicate an identical structure. Rather, the same reference number may be used to indicate a similar feature or a feature with similar functionality, as may non-identical reference numbers. The figures are drawn to scale (unless otherwise noted), meaning the sizes of the depicted elements are accurate relative to each other for at least the embodiment depicted in the figures.

In some embodiments, a connector assembly (e.g., 10) can be configured to couple a tubular (e.g., 22, 26) to a structure; for example, one of a female connector (e.g., 14) and a male connector (e.g., 18) of the connector assembly can be coupled to the structure, and the other of the female connector and the male connector can be coupled to the tubular. Such a structure can include any suitable structure, such as, for example, a blowout preventer, blowout preventer stack, lower marine riser package, diverter, a component thereof, and/or the like.Female connector 14 andmale connector 18 can comprise any suitable material, such as, for example, steel, aluminum, and/or the like. - Referring additionally to
FIGS. 2A-2G , shown isfemale connector 14.Female connector 14 can include asidewall 38 a that extends between afirst end 42 a and asecond end 46 a to define aninterior channel 50 a. As described in more detail below,first end 42 a offemale connector 14 can be coupled tomale connector 18.Second end 46 a offemale connector 14 can be coupled to a tubular (e.g., 22). For example, in this embodiment,second end 46 a offemale connector 14 can be received by the tubular. Atsecond end 46 a, anouter surface 54 a ofsidewall 38 a can have a shape and dimensions that correspond to a shape and dimensions of an inner surface of the tubular. To illustrate,outer surface 54 a ofsidewall 38 a atsecond end 46 a and an inner surface of the tubular can each be cylindrical, with the outer surface of the sidewall having a diameter that is substantially equal to (e.g., but slightly smaller than) a diameter of the inner surface of the tubular.Sidewall 38 a can taper in thickness atsecond end 46 a to, for example, facilitate coupling of the tubular to the female connector. In some instances, the tubular can be secured tofemale connector 14 via, for example, one or more welds (e.g., alongledge 102 a, described below), one or more fasteners (e.g., disposed through the tubular and into the female connector), one or more clamps (e.g., disposed around at least a portion of the tubular), and/or the like. In other embodiments, a female connector (e.g., 14) can have a second end (e.g., 46 a) that is configured to be coupled to a tubular (e.g., 22) by receiving the tubular such that, for example, a portion of the tubular is at least partially surrounded by a sidewall (e.g., 38 a) of the female connector, is disposed within an interior channel (e.g., 50 a) of the female connector, and/or the like. In such embodiments, an inner surface (e.g., 58 a) of the sidewall at the second end can have a shape and dimensions that correspond to a shape and dimensions of an outer surface of the tubular. -
Sidewall 38 a offemale connector 14 can include afirst portion 70 that is disposed closer tofirst end 42 a than tosecond end 46 a and asecond portion 74 that is disposed closer to the second end than to the first end.First portion 70 can have a first maximum exteriortransverse dimension 78, andsecond portion 74 can have a second maximum exterior transverse dimension 82 that is smaller than the first maximum exterior transverse dimension (FIG. 2G ) (e.g., transverse dimension 82 can be 90% or less of transverse dimension 78). Similarly,first portion 70 can have a first maximum interiortransverse dimension 86, andsecond portion 74 can have a second maximum interiortransverse dimension 90 that is smaller than the first maximum interior transverse dimension (e.g.,transverse dimension 90 can be 90% or less of transverse dimension 86). - Outer surface 54 a of
sidewall 38 a (e.g.,first portion 70 and/or second portion 74) can include cylindrical portion(s); for example, at least a portion of the sidewall can include an outer cross-sectional perimeter that is circular (FIGS. 2C and 2D ). In some embodiments, a female connector (e.g., 14) can have a sidewall (e.g., 38 a), at least a portion of which (e.g., afirst portion 70 and/or a second portion 74) can include an outer cross-sectional perimeter that is elliptical, otherwise rounded, triangular, square, rectangular, and/or otherwise polygonal, whether having sharp or rounded vertices. -
Female connector 14 can include aledge 102 a extending fromouter surface 54 a ofsidewall 38 a (e.g., betweenfirst portion 70 and second portion 74) that can extend at least partially around a circumference of the outer surface.Ledge 102 a can facilitate coupling of a tubular (e.g., 22) tofemale connector 14 by, for example, abutting the tubular whensecond end 46 a ofsidewall 38 a is received within the tubular.Female connector 14 can include one ormore recesses 94 that are defined into and/or one or more protrusions that extend fromouter surface 54 a ofsidewall 38 a (e.g., keyway(s), key(s), spline(s), and/or the like), and the recess(es) and/or protrusion(s) can engage corresponding recess(es) and/or protrusion(s) defined into and/or extending from an inner surface of the tubular (e.g., to restrict rotation of the tubular relative to the female connector when the tubular is coupled to the female connector). - An
inner surface 58 a ofsidewall 38 a (e.g.,first portion 70 and/or second portion 74) can include cylindrical portion(s); for example, at least a portion of the sidewall can include an inner cross-sectional perimeter that is circular (FIGS. 2C and 2D ). In some embodiments, a female connector (e.g., 14) can have a sidewall (e.g., 38 a), at least a portion of which (e.g., afirst portion 70 and/or a second portion 74) can include an inner cross-sectional perimeter that is elliptical, otherwise rounded, triangular, square, rectangular, and/or otherwise polygonal, whether having sharp or round vertices. -
Female connector 14 can include aramp 114 extending frominner surface 58 a ofsidewall 38 a (e.g., betweenfirst portion 70 and second portion 74) that can extend at least partially around a circumference ofinterior volume 50 a.Ramp 114 can include asurface 118 that is inclined along a direction fromfirst end 42 a towardsecond end 46 a and relative to alongitudinal axis 34 a offemale connector 14. For example,surface 118 can be conical. At least a portion ofsurface 118 can be angularly disposed relative tolongitudinal axis 34 a at anangle 122 that is greater than or substantially equal to any one of, or between any two of: 7.5, 10.0, 12.5, 15.0, 17.5, 20.0, 22.5, 25.0, 27.5, 30.0, 32.5, 35.0, 37.5, 40.0, 42.5, 45.0, 50.0, 55.0, 60.0, or more degrees (e.g., approximately 10 degrees). Ramp 114 (e.g.,surface 118 thereof) can be configured to contactfirst end 42 b ofmale connector 18 when the male connector is coupled tofemale connector 14 to, for example, facilitate a seal between the male connector and the female connector (e.g.,surface 118 can be characterized as a tapered sealing surface). -
Female connector 14 can include a plurality oflugs 130 a (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more lugs) extending from and disposed circumferentially alonginner surface 58 a.Lugs 130 a offemale connector 14 can be configured to engage a plurality oflugs 130 b of male connector 18 (described below) when the male connector is coupled to the female connector. For example, each oflugs 130 a offemale connector 14 can include amating surface 134 a configured to contact at least one oflugs 130 b ofmale connector 18 when the male connector is coupled to the female connector.Mating surface 134 a of at least one oflugs 130 a can be inclined relative to a plane that is perpendicular tolongitudinal axis 34 a such that, for example, when the mating surface is in contact with one oflugs 130 b ofmale connector 18, rotation of the male connector relative to the female connector can urge the male connector further intointerior channel 50 a offemale connector 14. For example, at least a portion ofmating surface 134 a of at least one oflugs 130 a can be angularly disposed relative to a plane that is perpendicular tolongitudinal axis 34 a at anangle 138 a that is less than or substantially equal to any one of, or between any two of: 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 18, 20, 25, 30, 35, 40, 45, or more degrees (e.g., approximately 5 degrees). -
Lugs 130 a offemale connector 14 can extend alonginner surface 58 a a collectivecircumferential distance 142 a that is approximately equal to any one of, or between any two of: 50, 55, 60, 65, 70, 75, 80, or more % (e.g., approximately 75%) of a circumference of the inner surface (e.g., when viewed fromfirst end 42 a) (FIG. 2C ). In at least this way, depending on the configuration oflugs 130 b ofmale connector 18, lugs 130 a offemale connector 14 can support the male connector relative to the female connector along a majority of a circumference of the female connector, provide an increased surface area through which loads can be transferred between the male and female connectors, and/or the like. Circumferentially adjacent ones oflugs 130 a can be circumferentially spaced from one another alonginner surface 58 a to, for example, allow one oflugs 130 b ofmale connector 18 to pass between the adjacent ones of the lugs during coupling of the male connector to the female connector. For example, acircumferential distance 144 a between circumferentially adjacent ones oflugs 130 a can be greater than or substantially equal to awidth 146 b of one oflugs 130 b of male connector 18 (FIG. 2C ). Circumferentially adjacent ones oflugs 130 a can be longitudinally offset (e.g., in a direction aligned withlongitudinal axis 34 a) from one another. Such longitudinally offsetlugs 130 a can, via interaction withlugs 130 b ofmale connector 18, restrict rotation of the male connector relative tofemale connector 14. - At least one of
lugs 130 a can have awidth 146 a (e.g., measured along a circumference ofinner surface 58 a) and alength 150 a (e.g., measured in a direction that is aligned withlongitudinal axis 34 a) that is smaller than the width. For example, for at least one oflugs 130 a,length 150 a can be less than or substantially equal to any one of, or between any two of: 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, or more % ofwidth 146 a (e.g., approximately 40% of the width).Lugs 130 a can be configured to allow for a degree of misalignment betweenmale connector 18 andfemale connector 14 when coupling the male connector to the female connector, whether such misalignment is longitudinal (e.g., in whichlongitudinal axis 34 a offemale connector 14 is angularly disposed and/or offset relative tolongitudinal axis 34 b of male connector 18), rotational (e.g., in which lugs 130 a of the female connector would otherwise interfere withlugs 130 b of the male connector to prevent or frustrate coupling of the male connector to the female connector), and/or the like. For example,length 150 a of at least one oflugs 130 a can decrease in a direction along a circumference ofinner surface 58 a, the lug can taper in length along the circumference of the inner surface, the lug can include chamfered, beveled, and/or the like edge(s), and/or the like. For further example, at least one oflugs 130 a can include athickness 154 a that decreases along the lug in a direction along a circumference ofinner surface 58 a and/or in a direction aligned withlongitudinal axis 34 a. - Referring additionally to
FIGS. 3A-3F , shown ismale connector 18.Male connector 18 can include asidewall 38 b that extends between afirst end 42 b and asecond end 46 b to define aninterior channel 50 b. First end 42 b ofmale connector 18 can be coupled tofemale connector 14. More particularly,first end 42 b ofmale connector 18 can be received byfemale connector 14 such that, for example, the first end of the male connector is at least partially surrounded bysidewall 38 a of the female connector, is disposed withininterior channel 50 a of the female connector, and/or the like. To illustrate, anouter surface 54 b ofmale connector 18 atfirst end 42 b andinner surface 58 a offemale connector 14 atfirst end 42 a can each be cylindrical, with the outer surface of the male connector having a diameter that is substantially equal to (e.g., but slightly smaller than) a diameter of the inner surface of the female connector.Sidewall 38 b ofmale connector 18 can taper in thickness atfirst end 42 b to, for example, facilitate coupling of the male connector tofemale connector 14, define a (e.g., conical) sealingsurface 158 configured to contactsurface 118 oframp 114, and/or the like. Similarly, sidewall 38 a offemale connector 14 can taper in thickness atfirst end 42 a to, for example, facilitate coupling ofmale connector 18 to the female connector. -
Second end 46 b ofmale connector 18 can be coupled to a tubular (e.g., 26). For example, in this embodiment,second end 46 b ofmale connector 18 can be received by the tubular. Atsecond end 46 b,outer surface 54 b ofsidewall 38 b can have a shape and dimensions that correspond to a shape and dimensions of an inner surface of the tubular; to illustrate, the outer surface of the sidewall and the inner surface of the tubular can each be cylindrical, with the outer surface of the sidewall having a diameter that is substantially equal to (e.g., but slightly smaller than) a diameter of the inner surface of the tubular.Sidewall 38 b can taper in thickness atsecond end 46 b to, for example, facilitate coupling of the tubular to the male connector. In some instances, the tubular can be secured tomale connector 18 via, for example, one or more welds (e.g., alongledge 102 b, described below), one or more fasteners (e.g., disposed through the tubular and into the male connector), one or more clamps (e.g., disposed around at least a portion of the tubular), and/or the like. In other embodiments, a male connector (e.g., 18) can have a second end (e.g., 46 b) that is configured to be coupled to a tubular (e.g., 26) by receiving the tubular such that, for example, a portion of the tubular is at least partially surrounded by a sidewall (e.g., 38 b) of the male connector, is disposed within an interior channel (e.g., 50 b) of the male connector, and/or the like. In such embodiments, an inner surface (e.g., 58 b) of the sidewall at the second end can have a shape and dimensions that correspond to a shape and dimensions of an outer surface of the tubular. -
Outer surface 54 b ofsidewall 38 b can include cylindrical portion(s); for example, at least a portion of the sidewall can include an outer cross-sectional perimeter that is circular (FIGS. 3C and 3D ). In some embodiments, a male connector (e.g., 18) can have a sidewall (e.g., 38 b), at least a portion of which can include an outer cross-sectional perimeter that is elliptical, otherwise rounded, triangular, square, rectangular, and/or otherwise polygonal, whether having sharp or rounded vertices. -
Male connector 18 can include aledge 102 b extending fromouter surface 54 b ofsidewall 38 b that can extend at least partially around a circumference of the outer surface.Ledge 102 b can facilitate coupling of a tubular (e.g., 26) tomale connector 18 by, for example, abutting the tubular whensecond end 46 b ofsidewall 38 b is received within the tubular. Similarly tofemale connector 14,male connector 18 can include one or more recesses that are defined into and/or one or more protrusions that extend fromouter surface 54 b ofsidewall 38 b that can restrict rotation of the tubular relative to the male connector when the tubular is coupled to the male connector. -
Inner surface 58 b ofsidewall 38 b can include cylindrical portion(s); for example, at least a portion of the sidewall can include an inner cross-sectional perimeter that is circular (FIGS. 3C and 3D ). In some embodiments, a male connector (e.g., 18) can have a sidewall (e.g., 38 b), at least a portion of which can include an inner cross-sectional perimeter that is elliptical, otherwise rounded, triangular, square, rectangular, and/or otherwise polygonal, whether having sharp or round vertices. -
Male connector 18 can include a plurality oflugs 130 b (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more lugs) extending from and disposed circumferentially alongouter surface 54 b.Lugs 130 b ofmale connector 18 can be configured to engagelugs 130 a offemale connector 14 when the male connector is coupled to the female connector. For example, each oflugs 130 b ofmale connector 18 can include amating surface 134 b configured to contact at least one oflugs 130 a offemale connector 14 when the male connector is coupled to the female connector (FIG. 3E ).Mating surface 134 b of at least one oflugs 130 b can be inclined relative to a plane that is perpendicular tolongitudinal axis 34 b such that, for example, when the mating surface is in contact with one oflugs 130 a offemale connector 14, rotation ofmale connector 18 relative to the female connector can urge the male connector further intointerior channel 50 a of the female connector. For example, at least a portion ofmating surface 134 b of at least one oflugs 130 b can be angularly disposed relative to a plane that is perpendicular tolongitudinal axis 34 b at anangle 138 b that is less than or substantially equal to any one of, or between any two of: 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 45, or more degrees (e.g., approximately 5 degrees). -
Lugs 130 b ofmale connector 18 can extend alongouter surface 54 b a collectivecircumferential distance 142 b that is approximately equal to any one of, or between any two of: 50, 55, 60, 65, 70, 75, 80, or more % (e.g., approximately 75%) of a circumference of the outer surface (e.g., when viewed fromfirst end 42 b) (FIG. 3C ). In at least this way, depending on the configuration oflugs 130 a offemale connector 14, lugs 130 b ofmale connector 18 can support the female connector relative to the male connector along a majority of a circumference of the male connector, provide an increased surface area through which loads can be transferred between the male and female connectors, and/or the like. Circumferentially adjacent ones oflugs 130 b can be circumferentially spaced from one another alongouter surface 54 b to, for example, allow one oflugs 130 a offemale connector 14 to pass between the adjacent ones of the lugs during coupling of the male connector to the female connector. For example, acircumferential distance 144 b between circumferentially adjacent ones oflugs 130 b can be greater than or substantially equal to awidth 146 a of one oflugs 130 a of female connector 14 (FIG. 3C ). Circumferentially adjacent ones oflugs 130 b can be longitudinally offset (e.g., in a direction aligned withlongitudinal axis 34 b) from one another. Such longitudinally offsetlugs 130 b can, via interaction withlugs 130 a offemale connector 14, restrict rotation ofmale connector 18 relative tofemale connector 14. - At least one of
lugs 130 b can have awidth 146 b (e.g., measured along a circumference ofouter surface 54 b) and alength 150 b (e.g., measured in a direction that is aligned withlongitudinal axis 34 b) that is smaller than the width. For example, for at least one oflugs 130 b,length 150 b can be less than or substantially equal to any one of, or between any two of: 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, or more % ofwidth 146 b (e.g., approximately 40% of the width). Similarly tolugs 130 a, lugs 130 b can be configured to allow for a degree of misalignment betweenmale connector 18 andfemale connector 14 when coupling the male connector to the female connector. For example,length 150 b of at least one oflugs 130 b can decrease in a direction along a circumference ofouter surface 54 b, the lug can taper in length along the circumference of the outer surface, the lug can include chamfered, beveled, and/or the like edge(s), and/or the like. For further example, at least one oflugs 130 b can include athickness 154 b that decreases along the lug in a direction along a circumference ofouter surface 54 b and/or in a direction aligned withlongitudinal axis 34 b. - Referring additionally to
FIGS. 5A and 5B , male connector 18 (represented in dashed lines and as if viewed from inside of the male connector) can be coupled to female connector 14 (represented in solid lines) such thatsidewall 38 b of the male connector is at least partially received withininterior channel 50 a of the female connector. Whenmale connector 18 is coupled to female connector 14 (FIG. 5B ), at least one of (e.g., each of) lugs 130 b of the male connector can be: (1) disposed between at least one oflugs 130 a of the female connector andsecond end 46 a of the female connector (longitudinally between, meaning a distance measured alonglongitudinal axis 34 a between: (1) a plane that is perpendicular to the longitudinal axis and intersects the at least one lug of the male connector; and (2) a plane that is perpendicular to the longitudinal axis and intersects the second end of the female connector is less than a distance measured along the longitudinal axis between: (1) a plane that is perpendicular to the longitudinal axis and intersects the at least one lug of the female connector; and (2) the plane that is perpendicular to the longitudinal axis and intersects the second end of the female connector); and (2) in contact with the at least one lug of the female connector. Similarly, whenmale connector 18 is coupled tofemale connector 14, at least one of (e.g., each of) lugs 130 a of the female connector can be: (1) disposed between at least one oflugs 130 b of the male connector andsecond end 46 b of the male connector (longitudinally between, meaning a distance measured alonglongitudinal axis 34 b between: (1) a plane that is perpendicular to the longitudinal axis and intersects the at least one lug of the female connector; and (2) a plane that is perpendicular to the longitudinal axis and intersects the second end of the male connector is less than a distance measured along the longitudinal axis between: (1) a plane that is perpendicular to the longitudinal axis and intersects the at least one lug of the male connector; and (2) the plane that is perpendicular to the longitudinal axis and intersects the second end of the male connector); and (2) in contact with the at least one lug of the male connector. Thus, lugs 130 a and 130 b can cooperate to physically resist separation ofmale connector 14 andfemale connector 18 when the male connector is coupled to the female connector. -
FIGS. 6A-6E depict an exemplary method for coupling a male connector (e.g., 18, represented in dashed lines and as if viewed from inside of the male connector) to a female connector (e.g., 14, represented in solid lines). The female connector can include a sidewall (e.g., 38 a) extending between a first end (e.g., 42 a) and a second end (e.g., 46 a) to define an interior channel (e.g., 50 a), the sidewall having a cylindrical inner surface (e.g., 58 a), and a plurality of first lugs (e.g., 130 a 1) extending from and disposed circumferentially along the inner surface. The male connector can include a sidewall (e.g., 38 b) extending between a first end (e.g., 42 b) and a second end (e.g., 46 b) to define an interior channel (e.g., 50 b), the sidewall having a cylindrical outer surface (e.g., 54 a), and a plurality of first lugs (e.g., 130 b 1) extending from and disposed circumferentially along the outer surface. - As shown in
FIG. 6B , the first end of the male connector can be inserted through the first end of the female connector and at least partially into the interior channel of the female connector such that at least one of the first lugs of the male connector extends longitudinally beyond at least one of the first lugs of the female connector (e.g., such that a surface of the at least one first lug of the male connector that faces the second end of the male connector is disposed closer to the second end of the female connector than is a surface of the at least one first lug of the female connector that faces the second end of the female connector). As shown inFIG. 6C , once at least one of the first lugs of the male connector extends longitudinally beyond at least one of the first lugs of the female connector, the male connector can be rotated (e.g., generally in a direction indicated by arrow 160) relative to the female connector such that the at least one first lug of the male connector is: (1) disposed between the at least one first lug of the female connector and the second end of the female connector; and (2) in contact with the at least one first lug of the female connector. - Turning to
FIG. 6D , the male connector can comprise a plurality of second lugs (e.g., 130 b 2) extending from and disposed circumferentially along the outer surface, the second lugs being circumferentially and longitudinally offset relative to the first lugs of the male connector. The male connector can be further inserted into the female connector such that at least one of the second lugs of the male connector extends longitudinally beyond at least one of the first lugs of the female connector. As shown inFIG. 6E , once at least one of the second lugs of the male connector extends longitudinally beyond at least one of the first lugs of the female connector, the male connector can be further rotated (e.g., generally in a direction indicated by arrow 160) relative to the female connector such that the at least one second lug of the male connector is: (1) disposed between the at least one first lug of the female connector and the second end of the female connector; and (2) in contact with the at least one first lug of the female connector. - In some embodiments (e.g., 10), the female connector can include a plurality of second lugs (e.g., 130 a 2) extending from and disposed circumferentially along the inner surface, the second lugs being circumferentially and longitudinally offset relative to the first lugs of the female connector. As shown in
FIGS. 6D and 6E , in such embodiments, the further inserting can be performed such that at least one of the first lugs of the male connector extends longitudinally beyond at least one of the second lugs of the female connector, and the further rotating can be performed such that the at least one first lug of the male connector is: (1) disposed between the at least one second lug of the female connector and the second end of the female connector; and (2) in contact with the at least one second lug of the female connector. - Referring now to
FIGS. 7A-7C ,connector assembly 10 can include a lockingmember 162 configured to be coupled toconnector assembly 10 to resist separation ofmale connector 18 andfemale connector 14 when the male connector is coupled to the female connector. For example, lockingmember 162 can include one ormore tabs 166, each configured to contact at least one oflugs 130 a offemale connector 14 and/or at least one oflugs 130 b ofmale connector 18. Tab(s) 166, via contact with lug(s) 130 a offemale connector 14 and/or lug(s) 130 b ofmale connector 18, can restrict movement of the lugs relative to one another and thus restrict rotation and/or translation of the female connector relative to the male connector. To illustrate, and referring additionally toFIG. 8 , whenmale connector 18 is coupled tofemale connector 14 and lockingmember 162 is coupled toconnector assembly 10, at least one of tab(s) 166 (represented in dotted lines) can be disposed between adjacent ones oflugs 130 b of the male connector, between one of the lugs of the male connector and one oflugs 130 a of the female connector, between adjacent ones of the lugs of the female connector, and/or the like. - In this embodiment,
female connector 14 can define one or more openings 178 (e.g., throughledge 102 a) configured to receive one ormore tabs 166 of lockingmember 162 such that, for example, the tab(s) can extend through the opening(s) and intointerior channel 50 a to contact lug(s) 130 a offemale connector 14 and/or lug(s) 130 b ofmale connector 18. In some embodiments, a male connector (e.g., 18) can define one or more openings (e.g., 178) configured to receive one or more tabs (e.g., 166) of a locking member (e.g., 162). Tab(s) 166 can extend from abody 168.Body 168 of lockingmember 162 can at least partially surround female connector 14 (and/or a tubular 22 coupled to the female connector) and/or male connector 18 (and/or a tubular 26 coupled to the male connector) when the locking member is coupled to connector assembly 10 (e.g., the body can be annular). - Tab(s) 166 can have a shape that corresponds to the relative placement of
