Abstract
Various connectors are disclosed. The connectors include a sealing assembly for providing a seal around a cable extending through the connector. The sealing assembly can include a moveable shuttle, a sleeve, a stop component and a sealing boot. The sealing boot can be compressed between the sleeve and the shuttle as the shuttle moves towards the stop component. The sealing boot can be configured to change shape (e.g., buckle) around the cable in response to movement of the shuttle. The change in shape of the sealing boot can facilitate sealing around the cable. The connector can be configured to inhibit or prevent the sealing boot from being extruded of out of position in response to a pressure gradient between first and second ends of the connector.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
(24) The various features and advantages of the systems, devices, and methods of the connectors described herein will become more fully apparent from the following description of the several specific embodiments illustrated in the figures. These embodiments are intended to illustrate the principles of this disclosure, and this disclosure should not be limited to merely the illustrated examples. The features of illustrated embodiments can be modified, combined, removed, and/or substituted as will be apparent to those of ordinary skill in the art upon consideration of the principles disclosed herein.
(25) Overview (
(26)
(27) In some instances, the connector 100 can be used in harsh environments. As one example, in the oil and gas industry, the connector 100 can be used to connect to equipment (such as an electric submersible pump (ESP)) within a well. The connector 100 can be used for delivery of power and/or data to the ESP. The downhole environment of a well can be particularly harsh, experiencing high and/or low temperatures and pressures, large fluctuations in temperature and pressure, exposure to fluids (including corrosive fluids), and exposure to abrasive particles.
(28) The connector 100 includes a housing 400. The housing 400 can be substantially or generally cylindrical, although other shapes are possible. The housing 400 extends between a first end 402 and a second end 404. The housing 400 is shown in greater detail in
(29) A cable bundle 20 can extend into the interior of the housing 400 through the first end 402 of the housing 400 at the first end 102 of the connector 100. In certain embodiments, the cable bundle 20 can include a first cable 22, a second cable 24, and a third cable 26, as shown, for example, in
(30) The connector 100 includes a receptacle assembly 900. The receptacle assembly 900 can be positioned at the second end 104 of the connector 100. As shown, a portion of the receptacle assembly 900 extends outwardly from the second end 404 of the housing 400. The receptacle assembly 900 includes a socket 902. The socket 902 can be external to the housing 400. In the illustrated embodiment, the socket 902 includes three holes 904. Each hole 904 can be configured to receive a pin or plug on a corresponding connector (not shown). In some embodiments, each hole 904 corresponds to one of the first cable 22, the second cable 24, and the third cable 26 such that an electrical connection can be established with the first cable 22, the second cable 24, and the third cable 26 through the corresponding hole 904. The receptacle assembly 900 and the socket 902 are configured to allow the connector 100 to connect to a corresponding connector or other structure. Although the receptacle assembly 900 is illustrated with a female socket 902, other structures can also be used. For example, the receptacle assembly 900 can include a male plug. In some embodiments, the connector 100 includes a cap (not shown) that can be installed over the exposed end of the receptacle assembly 900. The cap can protect the receptacle assembly 900 when the receptacle assembly 900 is not connected to another connector. The receptacle assembly 900 is described in greater detail with reference to
(31) Although not shown in
(32) As shown in
(33) Within the interior of the housing 400, the cables 22, 24, 26 extend through the sealing assembly 300. The sealing assembly 300 can be positioned between the receptacle assembly 900 and the first end 402 of the housing 400. As will become more apparent from the following description, the sealing assembly 300 can be configured to create a seal around each of the cables 22, 24, 26. The seal can be a liquid seal or a pressure seal. In some embodiment, the seal prevents, substantially prevents, reduces, substantially reduces, limits, or substantially limits the movement of liquid, gases, particles, debris, dust, or other things, across the seal and/or through the connector 100.
(34) As illustrated, the sealing assembly 300 can include a biasing member, such as a spring 150. The spring 150 can be positioned between the first end 402 of the housing 400 and the shuttle 500. The spring 150 can be configured to bias the shuttle 500 toward the stop component 800. The spring 150 can be a linear coil spring, although other types of springs are possible. In some embodiments, the spring 150 comprises a plurality of springs. In some embodiments, the spring 150 can be positioned between the shuttle 500 and the stop component 800. The spring 150 can be configured to encourage the shuttle 500 in the direction of the stop component 800 and/or the sleeve 700. For example, the spring 150 can provide a compressive force that pushes, or a tensile force that pulls, the shuttle 500 towards the stop component 800 and/or the sleeve 700.
(35) As shown in
(36)
(37) As noted previously, in some embodiments, the connector 100 is exposed to a range of temperatures and/or pressures. The sealing assembly 300 can be configured to provide a seal around the cables 22, 24, 26 over a wide range of temperatures and/or pressures. In some embodiments, the position of the shuttle 500 moves to compensate for changes in temperature and/or pressure (compare, for example, the position of the shuttle 500 in
(38) In some embodiments, movement of the shuttle 500 may be caused by thermal expansion and/or contraction of one or more of the components of the connector 500. For example, a change in temperature may cause the shuttle 500, the sealing boots 600, and the sleeves 700 to expand or contract. Because these components may be made from different materials with different thermal expansion coefficients, the expansion or contraction may occur to different degrees or different rates for each of these components. As one example, the sealing boots 600 may expand more than the shuttle 500. As the sealing boots 600 expand faster than the bores of the shuttle 500 in which they are positioned, the sealing boots 600 may buckle or collapse to different degrees to automatically adjust. As the sealing boots 600 buckle or collapse to different degrees, the shuttle 500 may move longitudinally to accommodate the sealing boots 600.
(39) As another example, the shuttle 500 and the sleeves 700 may expand more than the sealing boots 600. This may cause the inner diameter of the bores within which the sealing boots 600 are positioned to become larger than an outer diameter of the sealing boots 600. The spring 150 can exert a force on the shuttle 500 that biases the shuttle 500 toward the stop component 800. The force of the spring 150 can compress the sealing boots 600 longitudinally between the shuttle 500 and the sleeves 700. As the sealing boots 600 are compressed, they may automatically buckle or collapse to different degrees so as to automatically fill the larger inner diameter of the bores of shuttle 500 caused by the thermal expansion of the components of the connector 100.
(40) In various embodiments, the shuttle 500 can move (e.g., slide) within the housing 400. In some embodiments, movement of the shuttle 500 may be caused by a pressure differential. For example, in some embodiments, the connector 100 can be positioned such that a first pressure acts on a first end of the shuttle 500 (for example, the right end of the shuttle 500 in

(85) In various embodiments, the engagement sleeve 700 inhibits or prevents the sealing boot 600 from being extruded, such as in response to a pressure differential. For example, the engagement sleeve 700 can provide physical stop against which the sealing boot 600 engages and/or is prevented from moving any further toward the second end 104 of the connector 100. In certain situations, such as at high pressures (e.g., about 5000 psi), rubber sealing elements (e.g., boot, o-rings, etc.) may tend to extrude through gaps larger than around 0.005 inches. In certain embodiments, the connector 100 is configured to inhibit or prevent extrusion of the sealing boot 600, such as extrusion between the outside diameter of the sleeve 700 and the inside diameter of the bore 510. In some embodiments, the outside of the shuttle 700 and the inside of the bore 510 are dimensioned and/or toleranced to inhibit extrusion of the sealing boot 600. For example, in some variants, the radial clearance (e.g., gap) between the outside of the shuttle 700 and the inside of the bore 510 is less than or equal to about: 0.001 inches, 0.002 inches, 0.004 inches, or other values.
(86) In several embodiments, the sealing boot 600 expands or collapses (e.g., buckles) in response to movements of the shuttle 500. For example, the sealing boot 600 can collapse in response to the shuttle 500 moving toward the stop 800 and/or can expand in response to the shuttle 500 moving away from the stop 800. The sealing boot 600 can collapse to a degree that is dependent upon the position of the shuttle 500. In some embodiments, the position that the shuttle 500 moves is dependent upon or affected by the degree to which the sealing boot 600 collapses. In some embodiments, the shuttle 500 moves and the sealing boot 600 collapses to different degrees to provide a seal over a range of temperatures and pressures. In some embodiments, the shuttle 500 moves and the sealing boot 600 collapses automatically in response to changes in temperature and pressure.
(87) In various embodiments, in response to the collapsing of the sealing boot 600, the outside and/or inside diameter of the sealing boot 600 changes. For example, the outside diameter can increase and/or the inside diameter can decrease. The change in outside and/or inside diameter can facilitate sealing the sealing boot 600 against the bore 510 and/or the cable 22. This sealing between the boot 600 and the bore 510 and/or the cable 22 can inhibit or prevent pressure from the first end 102 of the connector (e.g., at well pressure) from being transferred to the second end 104 of the connector 100 (e.g., at approximately atmospheric pressure).
Certain Additional Embodiments (FIGS. 11A-11C)
(88)
(89) The connector 1100 extends between a first end 1102 and a second end 1104. A cable bundle 1120 extends into a housing 1400 through the first end 1102. The cable bundle 1120 can include one or more cables (e.g., insulated electrical wires). For example, the illustrated embodiment has three cables 1122, 1124, 1126. As shown, a receptacle assembly 1900 can be positioned at the second end 1104.
(90) A sealing assembly 1300 can be positioned in the housing 1400. The sealing assembly 1300 can include a shuttle 1500, sealing boot 1600, sleeve 1700, and a stop component 1800. Some variants comprise multiple shuttles 1500, sealing boots 1600, sleeves 1700, and/or stop components 1800. A biasing member, such as spring 1150, can bias the shuttle 1500 toward the stop component 1800. The shuttle 1500 can be configured to move relative to the sleeve 1700 and/or the housing 1400. The sealing boot 1600 can be configured to collapse or buckle, such as in the manner described above. In various embodiments, the sealing boot 1600 moves longitudinally with the shuttle 1500.

(93) Certain Terminology
(94) Although systems, devices, and methods of the connectors have been disclosed in the context of certain embodiments and examples, it will be understood by those skilled in the art that the assemblies extend beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the embodiments and certain modifications and equivalents thereof. Use with any structure is expressly within the scope of this invention. Various features and aspects of the disclosed embodiments can be combined with or substituted for one another in order to form varying modes of the assembly. The scope of this disclosure should not be limited by the particular disclosed embodiments described herein.
(95) Certain features that are described in this disclosure in the context of separate implementations or embodiments can also be implemented in combination in a single implementation or embodiment. Conversely, various features that are described in the context of a single implementation or embodiment can also be implemented in multiple implementations or embodiments separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations, one or more features from a claimed combination can, in some cases, be excised from the combination, and the combination may be claimed as any subcombination or variation of any subcombination.
(96) Terms of orientation used herein, such as top, bottom, proximal, distal, longitudinal, lateral, and end, are used in the context of the illustrated embodiment. However, the present disclosure should not be limited to the illustrated orientation. Indeed, other orientations are possible and are within the scope of this disclosure. Terms relating to circular shapes as used herein, such as diameter or radius, should be understood not to require perfect circular structures, but rather should be applied to any suitable structure with a cross-sectional region that can be measured from side-to-side. Terms relating to shapes generally, such as circular, cylindrical, semi-circular, or semi-cylindrical or any related or similar terms, are not required to conform strictly to the mathematical definitions of circles or cylinders or other structures, but can encompass structures that are reasonably close approximations.
(97) Conditional language, such as can, could, might, or may, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include or do not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments.
(98) Conjunctive language, such as the phrase at least one of X, Y, and Z, unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z. Thus, such conjunctive language is not generally intended to imply that certain embodiments require the presence of at least one of X, at least one of Y, and at least one of Z.
(99) The terms approximately, about, and substantially as used herein represent an amount close to the stated amount that still performs a desired function or achieves a desired result. For example, in some embodiments, as the context may dictate, the terms approximately, about, and substantially, may refer to an amount that is within less than or equal to 10% of the stated amount. The term generally as used herein represents a value, amount, or characteristic that predominantly includes or tends toward a particular value, amount, or characteristic. As an example, in certain embodiments, as the context may dictate, the term generally parallel can refer to something that departs from exactly parallel by less than or equal to 20 degrees.
(100) Some embodiments have been described in connection with the accompanying drawings. The figures may be to scale, but such scale should not be limiting, since dimensions and proportions other than what are shown are contemplated and are within the scope of the disclosed invention. Distances, angles, etc. are merely illustrative and do not necessarily bear an exact relationship to actual dimensions and layout of the devices illustrated.
