Description

Technical Field

[0001] This invention relates to a connector, belonging to the field of connector technology. Background Technology

[0002] In the technology of insulated electrical connection, the electrical connection is set in a closed environment. This ensures that the electrical connection is absolutely isolated from the external environment, whether in a conventional application environment or in water, thus achieving both power supply and insulation.

[0003] In related technologies, connectors include a plug portion and a socket portion. The socket portion has a jack, and the plug portion has a plug end. The plug end is inserted into the jack and makes electrical contact with the conductor of the socket portion and is insulated from the inner wall of the jack, thereby achieving electrical connection between the socket portion and the plug portion.

[0004] However, existing connectors require inlet sealing, resulting in a longer assembly time. Summary of the Invention

[0015] The connector has a disconnected state and a plugged state. When the connector is in the disconnected state, the filler post fills the socket, and the second insulating member is sealed to the socket housing to isolate the filler conductor and the second conductor member from the external environment outside the socket.

[0032] In one possible implementation, the connector further includes an auxiliary mechanism comprising a insertion post and a pull-out post;

[0033] One end of the insert is fastened to the first conductor, and the second end of the insert is used to engage with the first end of the puller.

[0034] The socket housing also has a second through hole penetrating the socket housing, and the pull member is movably inserted into the second through hole. The second end of the pull member is fastened to the end of the filling post away from the plug.

[0035] In one possible implementation, the insert includes a first fixing plate and an insert rod, the first conductor is detachably mounted on the first fixing plate, one end of the insert rod is fastened to the first fixing plate, and the other end of the insert rod is used to engage with the first end of the puller.

[0036] In one possible implementation, the pull member includes a second fixing plate, a claw, and a pull post. One end of the pull post is fastened to the claw, and the other end of the pull post is fastened to the second fixing plate. The end of the filling post away from the plug is detachably connected to the second fixing plate, and the claw is used to engage with the second end of the insert member.

[0037] In one possible implementation, the connector further includes a first mating device, the first mating device including a rack and a first gear drive;

[0038] The plug includes a plug housing, and the first conductor is fastened to the plug housing;

[0039] One of the rack and the first gear drive is disposed on the plug housing, and the other is disposed on the socket housing;

[0040] When the connector switches between a disconnected state and a plugged state, the rack and the first gear drive engage with each other to bring the plug and the socket closer or further apart.

[0041] In one possible implementation, the connector further includes a second mating device, the second mating device including a first toothed seat, a second toothed seat, and a second gear drive;

[0042] The second gear drive member meshes with the first gear seat and the second gear seat respectively. The second gear drive member is used to drive the first gear seat to move relative to the second gear seat, and is also used to drive the second gear seat to move relative to the first gear seat.

[0043] The first conductor is mounted on the first toothed seat, and the filler post is mounted on the second toothed seat.

[0044] In one possible implementation, the second gear drive includes a base, a second gear, and a third gear;

[0045] The second gear and the third gear are respectively rotatably connected to the base;

[0048] The connector provided by this invention includes a plug and a socket; the plug includes a first conductor, which includes a plug conductor and a first insulator; a first end of the plug conductor is used for electrical connection with a plug wire; the first insulator is used to seal the connection between the plug conductor and the plug wire, and for sealing connection with the socket housing; the socket includes a filler post, a socket housing, and a second conductor, the filler post including a second insulator and a filler conductor; the socket housing has a through-hole; the second conductor is installed inside the socket housing; a second end of the filler conductor is used for connection with a socket wire; the second insulator is used to seal the connection between the filler conductor and the socket wire, and for sealing connection with the socket housing; the connection... The connector has a detached state and a plugged state. When the connector is in the detached state, the filler post fills the socket, and the second insulating member is sealed to the socket housing to isolate the filler conductor and the second conductor from the external environment outside the socket. When the connector is in the plugged state, the first conductor fills part of the socket, the filler post fills part of the socket, and the second conductor is in electrical contact with the plug conductor and the charging conductor, respectively. The filler conductor, the second conductor, and the plug conductor are isolated from the external environment outside the socket. During the process of switching the connector from the detached state to the plugged state, the first conductor and the filler post move in the same direction within the socket, and the first and second insulating members are sealed to the socket housing. Since the socket penetrates the socket housing, as the first conductor is inserted into the socket, the filler post moves in a direction away from the first conductor, so that part of the socket is replaced by the first conductor instead of the filler post. Therefore, the plugging and socket connection is not affected by water pressure, and the connector can switch between the plugged and detached states regardless of the water depth. In addition, since the plug wire is insulated from and electrically connected to the first conductor, and the socket wire is insulated from and electrically connected to the filler post, the connector does not need to be sealed at the inlet during field assembly, which helps to reduce the connector assembly time.

[0071] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0073] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0074] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0077] The connectors used in related technologies are mainly divided into two types: dry connectors and wet-mating connectors. The first type: On land, the plug and socket of a dry connector are assembled together by a threaded connection to form a sealed cavity. The cable connection is placed inside the sealed cavity, and then the connected connector is placed in water. However, when using dry connectors in deep-sea environments, it is difficult to place the connectors in such environments. Furthermore, due to the sealed cavity, the high water pressure in the deep sea could damage the components inside. Otherwise, the wall thickness of the entire dry connector would need to be very thick, increasing the cost. The second type: Wet-mating connectors are used for insertion and removal underwater. Since insertion and removal underwater is affected by water pressure, the socket part of the wet-mating connector has an oil-filled pressure balancing structure. When the plug conductor is inserted into the socket, the plug conductor pushes an insulating piston inside the socket, which in turn pushes insulating oil to transfer, thus balancing the pressure. The plug conductor contacts the second conductor inside the socket for conductivity and is sealed to the socket by a sealing ring. Therefore, while dry connectors are unaffected by water pressure during insertion and removal, their deployment is difficult and their structural stability is easily affected by water pressure, making them unsuitable for deep-sea environments. Wet-plug connectors, although applicable to deep-sea environments, require an additional pressure balancing structure to ensure the pressure inside the socket is the same as or close to the external pressure, allowing for insertion and removal of the plug and socket. However, as the water depth increases, the water pressure also rises, weakening the pressure balancing effect of the structure and increasing the difficulty of inserting wet-plug connectors.

[0078] In addition, to ensure the proper functioning of the connector, the connector inlet needs to be sealed to prevent water from entering through the corresponding inlets at the connections between the plug conductors and plug wires, and between the socket conductors and socket wires, thus preventing connector leakage. One sealing method in related technologies is potting technology, which mainly involves injecting liquid potting material, such as resin, into the inlet. After the potting material cures, it forms a seal that seals the inlet. However, this method is cumbersome and time-consuming. Another sealing method in related technologies uses pressurized rubber material to seal the inlet; however, this method leaves a cavity in the connector, which can damage the connector in deep water.

[0079] In view of this, the present disclosure provides a connector comprising a plug and a socket. The socket has a through-hole that communicates with the environment surrounding the socket, so that the internal pressure of the through-hole is equal to the water pressure around the socket, thus eliminating a pressure difference. When the socket and plug are inserted, the movement of the first conductor and the filler post is similar to the first conductor pushing the filler post, in other words, similar to the replacement of internal substances, thus eliminating a pressure difference and eliminating the need for an additional pressure balancing structure, which helps simplify the connector structure and reduce costs. Furthermore, by adopting a modular design approach, the socket wires and filler post form a module, and the plug wires and first conductor form a module, thus eliminating the inlet port found in related technologies. Therefore, during field assembly of the connector, sealing of the inlet port is no longer required, which helps reduce assembly time.

[0080] The connector provided by the present invention will be described in detail below with reference to specific embodiments.

[0081] Figure 1 This is a cross-sectional view of the first type of connector in a separated state provided in this embodiment. Figure 2 This is a cross-sectional view of the first type of connector in the mating process provided in this embodiment. Figure 3 This is a cross-sectional view of the first type of connector in the plugged-in state provided in this embodiment. Figures 1-3 As shown, the connector 10 provided in this embodiment includes a plug 20 and a socket 30. The plug 20 and the socket 30 can be plugged into or detached from each other, so that the connector 10 has a disconnected state or a plugged-in state. When the connector 10 is in the plugged-in state, the plug 20 and the socket 30 are electrically connected, so that the plug wire 71 and the socket wire 72 are electrically connected. When the connector 10 is in the disconnected state, the plug 20 and the socket 30 are disconnected, so that the plug wire 71 and the socket wire 72 are disconnected.

[0082] Figure 4 for Figure 1 A cross-sectional view of a partial structure of the connector in the illustrated embodiment. Figure 5 for Figure 3 A cross-sectional view of a portion of the connector structure in the illustrated embodiment. (As shown...) Figure 4 and Figure 5As shown, the plug 20 may include a first conductor 21, which includes a plug conductor 211 and a first insulator 212. A first end of the plug conductor 211 is used for electrical connection with one end of the plug wire 71. A portion of the first insulator 212 is sleeved on the plug conductor 211, and another portion is sleeved on the plug wire 71, thereby sealing the connection between the plug conductor 211 and the plug wire 71. The second end of the plug conductor 211 is not covered by the first insulator 212, ensuring that the plug conductor 211 can make electrical contact with the second conductor 33.

[0083] like Figure 1 As shown, the socket 30 may include a filler post 31, a socket housing 32, and a second conductor 33. The socket housing 32 has a through-hole 34 for inserting the filler post 31 and / or the first conductor 21 to achieve electrical connection between the plug 20 and the socket 30. The second conductor 33 is installed inside the socket housing 32. When the connector 10 is in the plugged-in state, the first and second ends of the second conductor 33 make electrical contact with the second end of the plug conductor 211 and the first end of the filler conductor 311, respectively, to achieve electrical connection between the socket 30 and the plug 20. Figure 4 and Figure 5 As shown, the filler post 31 may include a second insulator 312 and a filler conductor 311. A second end of the filler conductor 311 is electrically connected to one end of the socket wire 72. A portion of the second insulator 312 is disposed on the filler conductor 311, and another portion of the second insulator 312 is disposed on the socket wire 72, and the connection between the filler conductor 311 and the socket wire 72 is sealed by the second insulator 312.

[0084] When connector 10 is in the detached state, such as Figure 1 and Figure 4 As shown, the electricity within the plug 20 is isolated between the plug wire 71 and the plug conductor 211, with the second end of the plug conductor 211 exposed. Figure 1 and Figure 4 As shown, the filling post 31 partially fills the socket 34, the second insulating member 312 is sealed to the socket housing 32, and the filling conductor 311 does not contact the second conductor 33. Because the socket housing 32 and the second insulating member 312 are sealed together, the filling conductor 311 and the second conductor 33 are always isolated from the external environment outside the socket 30. Water outside the socket 30 will not come into contact with the filling conductor 311 and the second conductor 33, ensuring that the electricity within the socket wire 72 is isolated within the socket housing 32.

[0085] It should be noted that, in the separated state, the second conductor 33 can also make electrical contact with the filler conductor 311.

[0086] When connector 10 is in the plugged-in state, such as Figure 1 and Figure 5 As shown, the first conductor 21 fills a portion of the socket 34, and the filling post 31 also fills a portion of the socket 34. The first end of the second conductor 33 is in electrical contact with the second end of the plug conductor 211, and the second end of the second conductor 33 is in electrical contact with the first end of the filling conductor 311, thus achieving an electrical connection between the filling conductor 311 and the plug conductor 211. Consequently, the plug wire 71 can be electrically connected to the socket wire 72. Furthermore, since the first insulating member 212 and the second insulating member 312 are sealed together with the socket housing 32, the connection points between the filling conductor 311 and the plug conductor 211 and the second conductor 33 are sealed, thereby isolating them from the external environment outside the socket 30. This ensures that the electricity at the electrical connection point between the socket 30 and the plug 20 is isolated within the socket housing 32.

[0087] During the process of connector 10 switching from a disconnected state to a plugged state, the first conductor 21 and the filler post 31 move in the same direction within the socket 34, such as... Figure 2 As shown, when the first conductor 21 is inserted into the socket 34 from left to right, the filling post 31 moves from left to right within the socket 34. Specifically, when the length of the first conductor 21 inserted into the socket 34 is a first length, the distance the filling post 31 moves to the right is also a first length. In other words, the filling post 31 moves the same amount as the first conductor 21 is inserted, until the second conductor 33 makes electrical contact with both the filling conductor 311 and the plug conductor 211. Furthermore, during the insertion of the first conductor 21 into the socket 34, the first insulating member 212 and the second insulating member 312 are simultaneously sealed to the socket housing 32, ensuring that the plug conductor 211, the second conductor 33, and the filling conductor 311 are always isolated from the external environment outside the socket 30.

[0088] It should be noted that in some embodiments, the distance that the filling post 31 moves to the right may also be a second length that is less than the first length. In this case, there is a gap between the first conductor 21 and the filling post 31, but there is communication with the environment outside the socket 34 and the outlet 30. Thus, the pressure in the gap between the first conductor 21 and the filling post 31 can be equal to the pressure outside the outlet 30, and will not affect the insertion of the first conductor 21 into the socket 34.

[0089] like Figure 5As shown, when the first conductor 21 is inserted into the socket 34, the first conductor 21 can abut against the filling post 31, thereby allowing the first conductor 21 to push the filling post 31 to move. This helps reduce the difficulty of moving the filling post 31 and also avoids gaps between the filling post 31 and the first conductor 21. Of course, in some embodiments, the power for moving the filling post 31 may not include the pushing force applied to the filling post 31 by the first conductor 21, which can be achieved by the auxiliary mechanism 40 described below.

[0090] In one possible implementation, such as Figure 5 As shown, the plug conductor 211 may include a first conductor portion 2111 and a second conductor portion 2112. The two ends of the first conductor portion 2111 are electrically connected to the second conductor portion 2112 and the plug wire 71, respectively. The second conductor portion 2112 is used for electrical contact with the second conductor member 33. A portion of the first insulating member 212 covers the first conductor portion 2111, and another portion of the first insulating member 212 covers a portion of the plug wire 71, thereby sealing the connection between the first conductor portion 2111 and the plug wire 71. With this structure, the outer peripheral surface of the first insulating member 212 can be coplanar with the outer peripheral surface of the second conductor portion 2112, preventing a cavity from forming between the first conductor member 21 and the inner wall of the socket 34, which would affect the sealing performance of the first conductor member 21 and the socket housing 32.

[0091] The first conductor portion 2111 has a rod-shaped structure, such as a round rod or a prism rod.

[0092] The second conductor portion 2112 can be a block, plate, or column structure, for example, the second conductor portion 2112 can be a circular plate.

[0093] In one possible implementation, such as Figure 1 As shown, the socket housing 32 may include an insulating elastic element 321 and a socket outer shell 322. The socket outer shell 322 has a first through hole penetrating through it. The insulating elastic element 321 is fastened within the first through hole and forms a socket 34; in other words, the insulating elastic element 321 is a hollow tubular structure. Furthermore, the inner wall of the insulating elastic element 321 is used to make close contact with at least one of the filler post 31 and the first insulating element 212, achieving a sealed connection between the filler post 31 and the first insulating element 212 and the insulating elastic element 321. By interfering with the insulating elastic element 321 with at least one of the filler post 31 and the first insulating element 212, the sealing performance between the socket housing 32 and the filler post 31 and / or the first insulating element 212 can be improved.

[0094] The insulating elastic element 321 is made of insulating materials that can be elastically deformed, such as silicone rubber and polyurethane.

[0095] The socket housing 322 can be used to fix the insulating elastic member 321, thereby avoiding the increased difficulty of the first conductor member 21 moving in the socket 34 due to the deformation of the insulating elastic member 321 when the first conductor member 21 is inserted into the socket 34.

[0096] The specific structure of the socket housing 322 is not limited here. For example, in some embodiments, such as Figure 1 As shown, the socket housing 322 may include a first inner housing portion 3221, a first outer housing portion 3222, and a first annular plate portion 3223. The first inner housing portion 3221 is disposed within the first outer housing portion 3222 and, together with the first outer housing portion 3222, defines at least one through-hole, and the first inner housing portion 3221 also defines a second through-hole for accommodating a pull plate member. The first annular plate portion 3223 is fastened to one end of the first outer housing portion 3222. The socket wire 72 passes through the first annular plate portion 3223 and is spaced apart from it.

[0097] To ensure electrical connection between the filler conductor 311 and the plug conductor 211 via the second conductor 33, the second conductor 33 is mounted on the insulating elastic member 321. The second conductor 33 can be mounted on the inner wall of the socket 34. Alternatively, a portion of the second conductor 33 may be located inside the insulating elastic member 321, with its first and second ends exposed within the socket 34. Therefore, the connection method between the second conductor 33 and the insulating elastic member 321 can be determined based on the structure of the second conductor 33, and is not limited here.

[0098] In one possible implementation, such as Figure 5 As shown, the second conductor 33 may include a connecting portion 331, a first contact portion 332, and a second contact portion 333. The two opposite ends of the connecting portion 331 are electrically connected to the first ends of the first contact portion 332 and the first ends of the second contact portion 333, respectively. The connecting portion 331 is enclosed by the socket housing 32, thus the connecting portion 331 is located within the socket housing 32. The first contact portion 332 and the second contact portion 333 are spaced apart along the axial direction of the socket 34. Both the first contact portion 332 and the second contact portion 333 are embedded in the inner wall of the socket 34, and are exposed within the socket 34. In the plugged-in state, the first contact portion 332 is in electrical contact with the second end of the plug conductor 211, and the second contact portion 333 is in electrical contact with the second end of the filler conductor 311. With this structure, the second conductor 33 can make electrical contact with both the filler conductor 311 and the plug conductor 211, thereby achieving electrical connection between the plug wire 71 and the socket wire 72.

[0099] The structure of the connecting part 331 can be a rod-shaped structure, a sheet-shaped structure, a plate-shaped structure, a hollow tubular structure, etc., and no specific limitation is made here. For example, in some embodiments, the connecting part 331 is a rod-shaped structure extending along the axial direction of the insertion hole 34.

[0100] The first contact portion 332 can be a rod-shaped structure, a sheet-shaped structure, a block-shaped structure, or an arc-shaped structure. For example, in some embodiments, the first contact portion 332 can be a semi-circular ring surrounding the filling column 31. Alternatively, in some embodiments, the first contact portion 332 can be a circular ring surrounding the filling column 31.

[0101] The second contact portion 333 can be a rod-shaped structure, a sheet-shaped structure, a block-shaped structure, or an arc-shaped structure. For example, in some embodiments, the second contact portion 333 can be a semi-circular ring surrounding the filling post 31. Alternatively, in some embodiments, the first contact portion 332 can be a circular ring surrounding the filling post 31.

[0102] It should be noted that when both the first contact portion 332 and the second contact portion 333 are annular, the connecting portion 331 can be a tubular structure surrounding the filling column 31. Alternatively, in some embodiments, the connecting portion 331 may include multiple connectors, which are spaced apart around the filling column 31.

[0103] It is understandable that when the socket housing 32 includes an insulating elastic element 321, the second conductor 33 is embedded in the insulating elastic element 321.

[0104] In one possible implementation, such as Figure 5 As shown, the filler conductor 311 may include a rod-shaped portion 3111 and a mating portion 3112. The mating portion 3112 is disposed in the middle of the rod-shaped portion 3111 and is used for electrical contact with the second contact portion 333 of the second conductor 33. One end of the rod-shaped portion 3111 is electrically connected to the socket wire 72. The rod-shaped portion 3111 and the mating portion 3112 define a stepped surface. The second insulating member 312 encloses the rod-shaped portion 3111, a portion of the socket wire 72, and a portion of the mating portion 3112, thereby sealing the connection between the rod-shaped portion 3111 and the socket wire 72 and ensuring that the mating portion 3112 can make electrical contact with the second contact portion 333 of the second conductor 33. With such a structure, the filler conductor 311 can improve the connection strength between the second insulating member 312 and the filler conductor 311 while ensuring electrical contact between the filler conductor 311 and the second conductor 33.

[0105] Since the rod-shaped portion 3111 and the mating portion 3112 define the stepped surface, the second insulating member 312 can be snapped into the filling conductor 311, thereby improving the connection strength between the second insulating member 312 and the filling conductor 311.

[0106] The structure of the mating part 3112 can be determined according to the structure of the second contact part 333. For example, the mating part 3112 can be a semi-circular ring or a circular ring surrounding the rod-shaped part 3111. When the mating part 3112 is a circular ring, the mating part 3112 can make electrical contact with the second contact part 333 after the filling column 31 rotates at any angle, without the need to position the filling column 31.

[0107] Continue to refer to Figure 5 A serrated portion 3113 may be provided on the outer wall of the end of the rod-shaped portion 3111 away from the socket wire 72. The serrated portion 3113 can improve the connection strength between the rod-shaped portion 3111 and the second insulating member 312. In some embodiments, the serrated portion 3113 may be an external thread. Alternatively, in some embodiments, the serrated portion 3113 may include a plurality of annular segments (not shown in the figure) spaced apart along the axial direction of the rod-shaped portion 3111, each annular segment being sleeved on the rod-shaped portion 3111. Of course, the structure of the serrated portion 3113 is not limited to the two structures described above.

[0108] In one possible implementation, such as Figure 1 As shown, the connector 10 may also include an auxiliary mechanism 40, which is used to move the filler post 31 when the first conductor 21 is inserted into the socket 34, so as to ensure that the first conductor 21 can be inserted into the socket 34 until the second conductor 33 makes electrical contact with the plug conductor 211 and the filler conductor 311 respectively.

[0109] like Figure 1 As shown, the auxiliary mechanism 40 may include a plug 41 and a puller 42. One end of the plug 41 is fastened to the first conductor 21, and the second end of the plug 41 is used to engage with the first end of the puller 42. The socket housing 32 also has a second through hole penetrating the socket housing 32, and the puller 42 is movably inserted into the second through hole. The second end of the puller 42 is fastened to the end of the filler post 31 away from the plug 20.

[0110] like Figure 2 and Figure 3 As shown, during the insertion of the first conductor 21 into the socket 34, due to the engagement between the insertion post 41 and the puller 42, as the first conductor 21 moves to the right, the insertion post 41 also moves to the right, pushing the puller 42 to the right. This, in turn, pulls the filling post 31 to the right until the second conductor 33 makes electrical contact with both the filling conductor 311 and the plug conductor 211. When the first conductor 21 is to be pulled out of the socket 34, as the first conductor 21 moves to the left, the insertion post 41 also moves to the left simultaneously, pulling the puller 42 to the left until the first conductor 21 is pulled out of the socket 34.

[0111] It should be noted that after the first conductor 21 is pulled out of the socket 34, the snap-fit ​​relationship between the plug 41 and the pull-out member 42 is released, which can separate the plug 20 and the socket 30.

[0112] In one possible implementation, such as Figure 1 As shown, the insert member 41 may include a first fixing plate 411 and an insert rod 412. The first conductor member 21 is detachably mounted on the first fixing plate 411, one end of the insert rod 412 is fastened to the first fixing plate 411, and the other end of the insert rod 412 is used to engage with the first end of the pull member 42.

[0113] The insertion rod 412 can be fastened to the first fixing plate 411 by means of threaded connection, snap-fit, etc., and there are no restrictions here.

[0114] The first conductor 21 can be fastened to the first fixing plate 411 by means of snap-fit, threaded connection, etc., and there are no restrictions here.

[0115] In one possible implementation, such as Figure 1 As shown, the plug 412 may include a rod-shaped segment 4121 and a plug segment 4122. The two ends of the rod-shaped segment 4121 are respectively fastened to the plug segment 4122 and the first fixing plate 411.

[0116] In one possible implementation, such as Figure 1 As shown, the pull-out member 42 may include a second fixing plate 421, a claw 422, and a pull-out post 423. One end of the pull-out post 423 is securely connected to the claw 422, and the other end of the pull-out post 423 is securely connected to the second fixing plate 421. The end of the filling post 31 away from the plug 20 is detachably connected to the second fixing plate 421, and the claw 422 is used to engage with the second end of the insertion post 41.

[0117] The 422 claw can be fastened to the pull plate column by means of threaded connection, snap-fit, etc., and there are no restrictions here.

[0118] The pull plate column can be fastened to the second fixing plate 421 by means of threaded connection, snap-fit, etc., and there are no restrictions here.

[0119] The filling column 31 can also be fastened to the second fixing plate 421 by means of threaded connection, snap-fit, etc.

[0120] In one possible implementation, such as Figure 1 As shown, the connector 10 may further include a first mating device 50, which reduces the difficulty of plugging and unplugging the plug 20 and socket 30. Additionally, the plug 20 includes a plug housing 22, on which the first conductor 21 is securely mounted. Figure 1As shown, the first mating device 50 may include a rack 51 and a first gear drive 52. The rack 51 is disposed on the socket housing 32, and the first gear drive 52 is disposed on the plug housing 22. When the connector 10 switches between the disconnected state and the plugged state, the rack 51 and the first gear drive 52 mesh with each other, thereby more easily overcoming the interference force during the insertion and removal process. This allows the plug 20 and the socket 30 to move closer or further apart, helping to reduce the difficulty of inserting and removing the plug 20 and the socket 30. Here, the interference force refers to the interference force between the filling post 31 and the first conductor 21 and the inner wall of the socket 34.

[0121] Continue to refer to Figure 1 The plug housing 22 may include a hollow plug shell 221 and a support plate 222. The support plate 222 is installed inside the plug shell 221 and is used for fastening to the first conductor 21. The support plate 222 is provided with a through hole for the first conductor 21 to pass through.

[0122] When the auxiliary mechanism 40 is present, the first conductor 21 can be fastened to the support plate 222 via the first fixing plate 411. The first fixing plate 411 is fastened to the support plate 222, and the first conductor 21 passes through the support plate 222.

[0123] The specific structure of the plug housing 221 is not limited here. For example... Figure 1 As shown, the plug housing 221 may include a hollow second housing portion 2211 and a second annular plate portion 2212. The second annular plate portion 2212 is fastened to one end of the second housing portion 2211 and is sleeved on the plug wire 71 and spaced apart from the plug wire 71. A first conductor 21 is installed inside the second housing portion 2211 and fastened to it. The outer wall of the second housing portion 2211 is used for fastening to one of the rack 51 and the first gear drive member 52.

[0124] It is understood that in some embodiments, rack 51 may be mounted on plug housing 22 and first gear drive 52 may be mounted on socket housing 32.

[0125] In some embodiments, such as Figure 1 As shown, the first gear drive 52 may include a first gear 521, a rotating shaft 522, and a bracket 523. The first gear 521 is rotatably connected to the bracket 523 via the rotating shaft 522, and the bracket 523 is fastened to the plug housing 221, thereby the first gear drive 52 is mounted on the plug housing 221.

[0126] like Figure 1As shown, the first gear drive component 52 may also include a rotating rod 524, which is fastened to the rotating shaft 522. Operating the rotating rod 524 can drive the first gear 521 to rotate, thereby reducing the difficulty of using the first gear drive component 52.

[0127] Figure 6 This is a cross-sectional view of the second type of connector in a separated state provided in this embodiment. Figure 7 This is a cross-sectional view of the second type of connector in the mating process provided in this embodiment. Figure 8 This is a cross-sectional view of the second type of connector in the plugging state according to this embodiment. Figure 6 and Figure 1 The difference lies in the structure of the plug housing 22 and the socket housing 322. Figure 6 In this design, the plug housing 22 includes a third outer shell portion 2213 and a mounting plate portion 2214. The third outer shell portion 2213 is a hollow tubular structure. The mounting plate portion 2214 is disposed at one end of the third outer shell portion 2213 and is securely connected to it. The first conductor member 21 is securely connected to the mounting plate portion 2214 via a first fixing plate 411, and the mounting plate portion 2214 has a through hole through which the first conductor member 21 passes. Figure 6 In the socket housing 322, there are a fourth outer housing portion 3224 and a second inner housing portion 3225. The second inner housing portion 3225 is located inside the fourth inner housing portion and together with the fourth inner housing portion defines at least one first through hole, and the inner wall of the second inner housing portion 3225 defines a second through hole.

[0128] Figure 9 This is a cross-sectional view of the filling post of the third type of connector provided in this embodiment, showing the unfilled socket. Figure 10 A cross-sectional view of the process of filling the socket with the filling post of the third type of connector provided in this embodiment. Figure 11 This is a cross-sectional view of the third type of connector in a separated state provided in this embodiment. Figure 12 This is a cross-sectional view of the third type of connector in the mating process provided in this embodiment. Figure 13 This is a cross-sectional view of the third type of connector in the plugging state provided in this embodiment. Figure 9 and Figure 1 The difference lies in replacing the first docking device 50 with the second docking device 60. For example... Figure 9As shown, the second docking device 60 may include a first gear seat 61, a second gear seat 62, and a second gear drive member 63. The second gear drive member 63 meshes with both the first gear seat 61 and the second gear seat 62, and is used to drive the first gear seat 61 to move relative to the second gear seat 62, and also to drive the second gear seat 62 to move relative to the first gear seat 61. A first conductor member 21 is mounted on the first gear seat 61, and a filling post 31 is mounted on the second gear seat 62. The second docking device 60 can fill the socket 34 with the filling post 31 and drive the filling post 31 to move within the socket 34, and can also insert the first conductor member 21 into the socket 34, enabling the plug 20 and the socket 30 to be inserted and removed.

[0129] The working principle of the second docking device 60 is as follows: The socket housing 32 is fixed, and while the second gear drive 63 drives the second gear seat 62 to move to the left, the filling column 31 also moves to the left until it is inserted into the socket 34 (e.g., ...). Figures 9 to 11 As shown). Figures 12 to 13 As shown, when it is necessary to connect the plug 20 and the socket 30, the second driving member drives the first toothed seat 61 and the second toothed seat 62 to move to the right synchronously, thereby causing the filling post 31 and the first conductor 21 to move to the right synchronously until the second conductor 33 makes electrical contact with the filling conductor 311 and the plug conductor 211 respectively.

[0130] Continue to refer to Figure 9 The second gear drive component 63 may include a base 631, a second gear 632, and a third gear 633. The second gear 632 and the third gear 633 are rotatably connected to the base 631. Since the second gear 632 meshes with the first gear seat 61, its rotation causes the first gear seat 61 to move, allowing the first gear seat 61 to move relative to the second gear seat 62, enabling the first conductor 21 to be inserted into or removed from the socket 34. Similarly, since the third gear 633 meshes with the second gear seat 62, its rotation causes the second gear seat 62 to move, allowing the second gear seat 62 to move relative to the first gear seat 61, enabling the filling post 31 to be inserted into or move within the socket 34.

[0131] Continue to refer to Figure 9 The first gear seat 61 may include a first rack 51 and a first connecting seat 612. The first rack 51 is used to mesh with the second gear 632. The first connecting seat 612 is mounted on the first rack 51 and is fastened to the first fixing plate 411, thereby achieving a fast connection between the first gear seat 61 and the first conductor 21.

[0132] Of course, in some embodiments, the first conductor 21 may also be securely connected to the first connecting seat 612.

[0133] Continue to refer to Figure 9The second gear seat 62 may include a second rack 51 and a second connecting seat 623. The second rack 51 is used to mesh with the third gear 633. The second connecting seat 623 is mounted on the second rack 51 and is fastened to the second fixing plate 421, thereby achieving a fast connection between the second gear seat 62 and the second conductor 33.

[0134] Of course, in some embodiments, the second conductor 33 may also be securely connected to the second connecting seat 623.

[0135] It should be noted that since the first conductor 21 can be inserted into the socket 34 through the second docking device 60, the plug housing 22 is removed.

[0136] It should also be noted that, in order to ensure that the filling post 31 is inserted into or moves within the socket 34 under the action of the second docking device 60, the socket housing 32 and the second docking device 60 must not interfere with each other. Therefore, in some embodiments, the socket housing 32 can be as follows: Figure 6 The socket housing 32 in the middle.

[0137] It should be noted that when the connection between the second mating device 60 and the first conductor 21 and the filler post 31 is detachable, the second mating device 60 can be removed after the first conductor 21 is inserted into the socket 34. Since the filler post 31 can be filled into the socket 34 through the second mating device 60, if at least one of the filler post 31, the second conductor 33, and the first conductor 12 is damaged, the damaged component can be removed through the second mating device 60, thus eliminating the need to replace the entire connector 10 and reducing the maintenance cost of the connector 10.

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions 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.
