Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to an array connector. Background Technology

[0002] With the increasing emphasis placed on deep-sea resource development by the nation, and given the current instability in my country's surrounding waters, there is an urgent need to vigorously develop underwater unmanned equipment. As a key component of underwater unmanned equipment, connectors need to possess excellent waterproof performance and be able to operate stably for extended periods under extreme conditions such as high pressure and low temperature in the deep sea, ensuring continuous signal transmission and power supply. To adapt to the limited space of underwater unmanned equipment, the diameter of watertight connectors must not exceed 20mm, ensuring their installation and use within confined spaces without compromising the overall compactness and flexibility of the equipment. While existing array connectors can operate stably for extended periods under extreme conditions such as high pressure and low temperature in the deep sea, their large diameter and dimensions make them unsuitable for installation and use within the limited space of underwater unmanned equipment.

[0003] Chinese invention patent CN116959794A, published on October 27, 2023, discloses a segmented towed array vibration damping device and method. The device includes an array frame covered by an array sheath, with plug connectors and socket connectors at both ends of the sheath, sealing the sheath to form a closed cavity containing array filler. The array frame comprises a tension segment frame and an elastic segment frame. However, this towed array vibration damping device and its connectors have the following limitations, making it difficult to meet the development needs of next-generation underwater unmanned equipment: 1. The device in this invention patent is a complete functional segment integrating the frame, sheath, and filler. Its connectors, as end components of this large device, are bulky and cannot be miniaturized, making it difficult to meet the extremely compact requirements of key connecting components in underwater unmanned equipment; 2. The connector structure serves the macroscopic array load-bearing and vibration damping system, while also requiring specialized design for efficient electrical contact, multiple seals, tensile locking, and anti-misfit insertion mechanisms, resulting in a complex structure. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a miniaturized towed tensile array connector system, which solves the problem in the prior art that the towed array device has a large diameter and size, making it unsuitable for installation and use in the limited space of underwater unmanned equipment.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A miniaturized drag tensile segment connector system includes a plug connector with a plug mating assembly, a socket connector with a socket mating assembly, a connecting ring, and a tensile support; the plug mating assembly and the socket mating assembly are pluggable; the connecting ring is fastened to the outer periphery of the plug mating assembly and the socket mating assembly after plugging and mating for locking; the tensile support is installed at the tail of the plug mating assembly and / or the socket mating assembly for connecting a tensile cable.

[0007] Furthermore, the plug mating assembly includes a plug housing and a plug contact that is sealed within the plug housing by a glass sealing process; the socket mating assembly includes a socket housing and a socket contact that is sealed within the socket housing by a glass sealing process; the plug contact and the socket contact are electrically connected when the plug housing and the socket housing are plugged in.

[0008] Furthermore, the plug housing includes a coaxially arranged external threaded section of the plug and a male plug, as well as a square connecting seat 1 disposed between the external threaded section of the plug and the male plug; the socket housing includes a coaxially arranged external threaded section of the socket and a female plug, as well as a square connecting seat 2 disposed between the external threaded section of the socket and the female plug; the female plug and the male plug are inserted and mated; the external threaded section of the plug and the external threaded section of the socket are used to connect oil pipes.

[0009] Furthermore, the male plug has a sealing groove on its outer periphery for inserting a sealing ring, and the female plug is fitted onto the outside of the male plug. The inner wall of the female plug is interference-fitted with the sealing ring to achieve radial sealing.

[0010] Furthermore, both sides of the square connector seat one and the square connector seat two are provided with grooves, and the other two sides are provided with connector screw holes; the connecting ring includes two half connecting rings, and the two half connecting rings are provided with bosses that fit with the grooves and connecting ring screw holes that are aligned with the connector screw holes for passing through the screws to achieve fastening.

[0011] Furthermore, a matching anti-misinsertion structure is provided between the plug housing and the socket housing. The anti-misinsertion structure includes a guide pin provided on the mating end face of one of the plug housing and the socket housing and a guide groove provided on the mating end face of the other, with the guide pin and the guide groove engaging in a mating fit.

[0012] Furthermore, a circumferential groove is provided on the inner wall of the tail of the plug housing or socket housing, and notches are provided on the side of the circumferential groove at at least two opposite positions; the tensile bracket has a connecting plate, which can be inserted into the circumferential groove through the notch and rotated so that the opening on the connecting plate is aligned with the screw hole on the plug housing or socket housing, and fixed by a set screw.

[0013] Furthermore, the tensile support is "A" shaped, and the inner side of the tensile support is provided with an inner arch structure to avoid the wires and soldering cups led out from the tail of the plug docking assembly or socket docking assembly.

[0014] Furthermore, it also includes a separate oil-filled connector, which is connected to the tail of the socket mating assembly via an oil pipe.

[0015] Furthermore, the oil-filled connector includes an oil-filled housing and tensile supports at both ends of the oil-filled housing; the oil-filled housing includes a main cylinder and oil-filled threaded sections at both ends of the main cylinder, and the main cylinder has radial stepped threaded holes for inserting oil-filled screws.

[0016] The beneficial effects of this invention are:

[0017] 1. The plug and socket connector of the present invention optimizes the snap-fit ​​shape structure between the semi-connecting ring and the housing, thereby compressing the axial dimension between the semi-connecting ring and the housing;

[0018] 2. By optimizing the way the half-connecting ring is fixed with a screw, this invention not only increases the axial tensile strength between the plug housing and the socket housing, but also avoids the axial space occupation caused by the through holes and threaded holes required for screw installation on the side of the half-connecting ring.

[0019] 3. By setting up a connector anti-misfit insertion structure, the present invention not only plays a role in preventing misfitting, but also reduces the axial space occupied, and further reduces the radial dimension of the connector.

[0020] 4. This invention saves the axial space occupied by the oil-filled structure by making the oil-filled structure external as an oil-filled connector;

[0021] 5. The present invention, through a special inner arched support structure, allows the wire bonding cup to be located directly at the tail of the housing, avoiding the problem of increased axial dimensions caused by the need to use components such as adapter insulators and tail sleeves due to interference between the support and the wires near the wire bonding cup;

[0022] 6. This invention uses a glass sealing process to solidify the contact and the housing into one piece through a glass tube, thereby achieving the longitudinal watertight function of the connector;

[0023] 7. This invention achieves the cooperation between the tensile Kevlar rope and the support by designing a rope hole at the tail of the support. Furthermore, a semi-circular rounded corner and increased roughness requirements are designed at the rope hole to reduce the friction between the Kevlar rope and the rope hole.

[0024] 8. The present invention uses set screw holes designed on the plug housing, socket housing and oil-filled housing, which cooperate with the double grooves on the corresponding bracket connecting plate to achieve radial anti-torsion during axial tensile process;

[0025] 9. The present invention achieves axial tensile strength between the head and seat mating interfaces by the internal boss of the semi-connecting ring engaging with the grooves of the plug housing and socket housing.

[0026] 10. This invention achieves anti-loosening of the semi-connecting ring by designing connecting ring screw holes on the semi-connecting ring and connector screw holes on the housing, and by fixing the semi-connecting ring with anti-loosening screws, thus preventing the semi-connecting ring from radially loosening during dragging.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The miniaturized drag tensile strength array connector system described in Embodiment 1 of the present invention, such as Figures 1 to 9 As shown, the system is designed to strictly control the maximum outer diameter to within 20mm, thereby achieving the 20mm miniaturization requirement of the connector to meet the installation needs of underwater unmanned equipment or miniaturized towed arrays in extremely space-constrained environments. The connector system mainly includes plug connectors, socket connectors, and optional independent oil-filled connectors.

[0040] like Figure 1 As shown, plug connectors and socket connectors are the core electrical and mechanical connection units of the system. Figure 2 As shown, the plug connector mainly includes a plug mating assembly, a circular insulator component 8 disposed within the plug mating assembly, and a plug sealing cap 16 sleeved on the end of the plug mating assembly. A sealing ring 9 is provided between the plug mating assembly and the plug sealing cap 16; in this embodiment, the sealing ring is an O-ring. A semi-connecting ring 1 is provided on the outer side of the plug mating assembly and the plug sealing cap 16. Figure 3 As shown, the socket connector mainly includes a socket mating assembly and a socket sealing cover 13 inserted into the end of the socket mating assembly. A sealing ring 9 is provided between the socket mating assembly and the socket sealing cover 13. In this embodiment, the sealing ring is an O-ring. A semi-connecting ring 1 is provided on the outer side of the socket mating assembly and the socket sealing cover 13.

[0041] Furthermore, such as Figure 2 As shown, the semi-connecting ring 1 is snapped onto the outside of the plug mating assembly and the plug sealing cover 16 to connect the plug mating assembly and the plug sealing cover 16. Furthermore, the semi-connecting ring 1 is provided with a connecting ring screw hole 11, which can be aligned with the screw holes on the plug mating assembly and the plug sealing cover 16, and the connection and fastening of the plug mating assembly and the plug sealing cover 16 can be achieved by screwing in the screw 2.

[0042] Furthermore, such as Figure 3 As shown, the semi-connecting ring 1 is snapped onto the outside of the socket mating assembly and the socket sealing cover 13 to connect the socket mating assembly and the socket sealing cover 13. Furthermore, the semi-connecting ring 1 has a connecting ring screw hole 11 that can be aligned with the screw holes on the socket mating assembly and the socket sealing cover 13, and then the connection between the socket mating assembly and the socket sealing cover 13 is achieved by screwing in the screw 2.

[0043] The plug mating assembly can be inserted and mated with the socket mating assembly. When it is necessary to mate the plug connector with the socket connector, remove the half-connecting ring 1 and the corresponding plug sealing cover 16 and socket sealing cover 13 from the plug connector and socket connector, as shown below. Figure 1 As shown, the socket mating assembly is then inserted into the socket mating assembly. Two half-connecting rings 1 can be fastened to the plug mating assembly after insertion, forming a connecting ring with the outer side of the socket mating assembly, thus connecting the plug connector and the socket connector. The maximum outer diameter of the connector system at the connecting ring is no more than 20mm. Furthermore, both the plug mating assembly and the socket assembly have tensile supports 5 and fixing sleeves 4 at their tails.

[0044] Example 2 differs from Example 1 in that, as Figure 4 As shown, the plug mating assembly includes a plug housing 6 and a plug contact disposed within the plug housing 6. The plug contact is integrally sealed to the plug housing 6 using a glass sealing process. The socket mating assembly includes a socket housing 14 and a socket contact disposed within the socket housing 14. The socket contact is also integrally sealed within the socket housing 14 using a glass sealing process. The glass sealing process not only achieves reliable insulation and fixation between the contact and the housing, but also constitutes a longitudinal watertight barrier for the connector, ensuring no leakage occurs along the contact axis under deep-sea high pressure.

[0045] like Figure 4 As shown, the plug housing 6 consists of a coaxially arranged male plug 61, a square connector 62, and an external threaded section 63. Figure 7 As shown, the socket housing 14 consists of a female plug 141, a square connector 142, and a socket external thread section 143, all coaxially arranged. The square connector 142 connects the male plug 61 and the plug external thread section 63. The square connector 142 connects the female plug 141 and the socket external thread section 143. The female plug 141 and male plug 61 are inserted into each other, meaning the male plug 61 can be inserted into the female plug 141. When the female plug 141 and male plug 61 are inserted, the plug contact and the socket contact are engaged. In this embodiment, the contacts are 22# pinhole contacts, and one of the plug and socket contacts has a 22# open hole to facilitate engagement. The structure of the contact engagement parts is compatible with existing mature product series, ensuring the reliability of the electrical connection. The connection and disconnection of current and signals are achieved through the mating and separation of the contacts.

[0046] The external threaded section 63 of the plug and the external threaded section 143 of the socket are used to connect the oil pipe 2. A fixing sleeve 4 is fitted on the outside of the oil pipe 2 and fixed to the tail of the plug housing 6 and the socket housing 14.

[0047] Example 3 differs from Example 2 in that, as Figure 4 As shown, a sealing groove 611 is provided on the outer periphery of the male plug 61 for installing the sealing ring 9. Figure 1 As shown, when the female plug 141 is fitted onto the outside of the male plug 61, the inner wall of the female plug 141 is press-fitted with the sealing ring, that is, the inner wall of the female plug 141 presses against the sealing ring 9 to achieve radial sealing.

[0048] Example 4 differs from Example 2 in that, as Figure 2 As shown, the inner wall of the end of the male plug 61 is provided with an annular groove surrounding its axis, and a retaining spring 10 is provided in the annular groove.

[0049] Example 5 differs from Example 2 in that the locking and axial tensile functions of the plug and socket mating components are achieved through two semi-connecting rings 1. Figure 5 As shown, each half-connecting ring 1 is approximately U-shaped. After the openings of the two half-connecting rings 1 are joined, the outer surface has a cylindrical profile, while the inner surface is a rectangular space. The square connector seat 62 of the plug housing 6 has grooves on both sides and connector screw holes on the other two sides. The square connector seat 142 of the socket housing 14 has corresponding grooves on both sides and connector screw holes on the other two sides. Each half-connecting ring 1 has a boss 12 on one side of each of the two ends along the connector axial direction, which respectively mates with the grooves on the square connector seat 62 and the square connector seat 142. When the half-connecting rings 1 are engaged, the two bosses 12 of each half-connecting ring 1 respectively engage with the grooves on the square connector seat 62 and the square connector seat 142, achieving axial tensile strength. At least one connecting ring screw hole 11 is provided on each of the other two sides of each half-connecting ring 1. The connecting ring screw holes 11 are aligned with the connector screw holes on the square connector seat 62 and the square connector seat 142, respectively. The Narrow screw 2 is screwed into the connecting ring screw hole 11 and the corresponding connector screw hole on the half connecting ring 1 from the side of the square connecting seat and tightened to form a three-body locking structure of half connecting ring, screw and housing, which saves radial and axial space.

[0050] Furthermore, the outer edge of the groove on the square connector 62, i.e., the edge outside the half-connecting ring 1, has a protruding edge extending radially along the connector, which abuts against the end face of the half-connecting ring 1. The edge of the protruding edge is arc-shaped and flush with the outer peripheral surface of the half-connecting ring 1. Similarly, the outer edge of the groove on the square connector 142, i.e., the edge outside the half-connecting ring 1, has a protruding edge extending radially along the connector, which abuts against the other end face of the half-connecting ring 1. The edge of the protruding edge is arc-shaped and flush with the outer peripheral surface of the half-connecting ring 1. Additionally, as... Figure 7As shown, the outer contour of the female plug 141 is a rectangular cylindrical body. The two sides of the square connector seat 142 with connector screw holes are flush with the outer side of the female plug 141. The other two sides of the square connector seat 142 with grooves close to the female plug 141 are flush with the outer side of the female plug 141.

[0051] Example 6 differs from Example 5 in that, to achieve miniaturization and prevent incorrect insertion, a guide pin extending along the connector axis is provided on the square connecting seat 62 of the plug housing 6, and a guide groove is provided at the corresponding position of the female plug 141 of the socket housing 14. The guide pin and guide groove are respectively located on one side of the plug housing 6 and the socket housing 14. Normal insertion can only be achieved when the guide pin and guide groove are aligned, thus preventing incorrect insertion.

[0052] Example 7 differs from Example 2 in that, as Figure 2 and Figure 3 As shown, the tensile support 5 is connected to the tail of the plug external thread section 63 and the socket external thread section 143. (As indicated...) Figure 4 As shown, a circumferential groove is provided on the inner wall of the end of the external thread section 63 of the plug housing 6, and the opening of the circumferential groove faces the axis of the connector. Two notches distributed at 180 degrees are provided on the outer edge of the circumferential groove, near the end of the external thread section 63 of the plug, and screw holes are provided at 180 degrees at a certain distance from the notches. Corresponding screw holes are also provided on the other side edge of the circumferential groove. Two connecting plates are symmetrically provided at the end of the tensile support 5. After the two connecting plates are axially moved from the notches and inserted into the circumferential groove and rotated approximately 90 degrees, the connecting plates enter the circumferential groove so that the openings on the connecting plates are aligned with the screw holes of the circumferential groove. Set screws 7 are then used to fix the plates through the screw holes and openings, thereby achieving axial tensile strength and radial anti-rotation. Furthermore, this connection method of the tensile support 5 does not affect the connection of the oil pipe to the outer side of the external thread section 63 of the plug and the external thread section 143 of the socket.

[0053] Furthermore, in this embodiment, as Figure 6 As shown, the tensile support 5, as a key tensile structural component, is in the shape of an "A". Connecting plates are symmetrically arranged at the lower end of the "A"-shaped structure. The inner side of the "A"-shaped tensile support 5 has an inner arched structure to avoid the conductors near the soldering condenser.

[0054] Example 8, based on Example 7, focuses on how the independent design of the oil-filled connector can further optimize the axial dimensions.

[0055] like Figure 1 and Figure 8 As shown, to further reduce the axial dimension of the connector system, this embodiment externalizes the oil-filled structure as a separate oil-filled connector. This oil-filled connector is connected to the tail of the socket connector via an oil pipe 2.

[0056] The oil-filled connector mainly consists of an oil-filled housing 3, an oil-filled screw 15, and a fixing sleeve. The oil-filled housing 3 is the main structural component, with a central channel for the wire to pass through. It has oil-filled threaded sections at both ends and a radially stepped threaded hole 31 in the middle for installing the oil-filled screw 15 to achieve oil or glue filling. A sealing ring 9, or O-ring, is provided on the stepped surface of the stepped threaded hole, which is pressed together after the oil-filled screw 15 is tightened. The oil-filled threaded sections are used to connect to the oil pipe 2. A fixing sleeve 4 is fitted over the outside of the oil pipe 2. A tensile support 5 is connected to the oil-filled threaded section. The connection method between the tensile support 5 and the oil-filled threaded section is the same as the connection method between the tensile support 5 and the plug external threaded section 63 and the socket external threaded section 143.

[0057] By externalizing the oil-filling module, the axial space that would have been needed to accommodate the oil-filling structure in the plug and socket mating parts is effectively saved, making the overall layout of the connector system more compact and minimizing the length of the rigid section.

[0058] Example 9 illustrates the assembly, operation, and technical effects of the connector system described above.

[0059] When connection is required, remove the sealing caps from both the plug and socket connectors. Align the guide pins and guide grooves of the plug housing 6 and socket housing 14, then insert the male plug 63 into the female plug 143. Simultaneously, ensure reliable mating between the socket contact and the plug contact, achieving axial engagement of the plug and socket mating assemblies. Ensure the sealing ring 9 on the outer side of the male plug 63 is pressurized for sealing. Then, fasten the two semi-connecting rings 1 onto the outer periphery of the square connector, ensuring the boss 12 engages with the groove. Finally, screw in the Nappa screw 2 to lock it in place. An independent oil-filled connector can be pre-connected to the socket tail via the oil pipe 2.

[0060] During operation, the drag force is transmitted to the tensile support 5 via the Kevlar rope, and then through the boss-groove structure of the housing and semi-connecting ring 1, forming a reliable tensile path. The glass sealing structure ensures longitudinal watertightness, while the radial sealing ring ensures lateral watertightness. The guide pin-guide groove structure prevents mis-insertion. The external oil-filled connector achieves pressure balance while avoiding the accumulation of axial dimensions.

[0061] Ultimately, this system successfully integrates a connector with complete electrical connection, high reliability, watertightness, high tensile strength, and anti-misfit functions into a compact space with an outer diameter of no more than 20mm and an axial length (excluding the tail bracket) of approximately 30.7mm, perfectly solving the core problem that existing technologies cannot adapt to the limited installation space of underwater unmanned equipment.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
