DETAILED DESCRIPTION

[0038] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0039] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to "inside" and "outside" relative to the contour of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have sequentiality and importance; the "first direction" is the axial direction of the limiting cavity. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0040] The limiting member and the connector plug in the exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0041] like Figures 1 to 9 As shown, in the first aspect of the present disclosure, a limiting member of a connector plug is provided, the limiting member is used to be arranged between the sealing ring 11 and the end cover 12 of the connector plug, the limiting member includes a body 1, the body 1 includes a limiting cavity 2 for allowing the cable 18 to pass through, and at least part of the inner side wall of the limiting cavity 2 is used to fit with the cable 18. When the cable 18 is connected to the connector plug, it will pass through the limiting cavity 2. When the cable 18 outside the connector plug deflects or bends, since the inner side wall of the limiting cavity 2 will fit with the cable 18, it can limit the radial movement distance of the cable 18 inside the connector plug to a certain extent, and even avoid the radial movement of the cable 18 inside the connector plug. Therefore, the limiting member can reduce at least part of the external force exerted by the cable 18 on the sealing ring 11, thereby preventing the sealing ring 11 from being dislocated due to the external force caused by the deviation or bending of the cable, thereby ensuring the sealing of the connector plug.

[0042] In some embodiments of the present disclosure, Figures 1 to 3 As shown, the body 1 includes a first body 101 and a second body 102, and the second body 102 is detachably connected to the first body 101 to enclose the first body 101 together with the first body 101 to form a limiting cavity 2. The body 1 adopts a split design, and the limiting member can be directly set between the sealing ring 11 and the end cover 12 or removed from between the sealing ring 11 and the end cover 12 by assembling or disassembling the first body 101 and the second body 102, without considering the installation order, so as to facilitate the disassembly and assembly of the limiting member.

[0043] Among them, Figures 1 to 3 As shown, the first body 101 and the second body 102 can both be constructed as a semicircular ring structure, that is, the structures of the first body 101 and the second body 102 can be the same. This can facilitate the manufacture of the first body 101 and the second body 102 on the one hand, and on the other hand, it can also facilitate the assembly of the two, saving manufacturing costs while improving the disassembly and assembly efficiency of the limit parts.

[0044] Of course, the structures of the first body 101 and the second body 102 may also be different. For example, the first body 101 may be a three-quarter ring, and the second body 102 may be a quarter ring. As long as the two can be sleeved on the outer side of the cable 18 after being connected, the present disclosure does not limit this.

[0045] In some embodiments not shown, the body 1 may also be constructed as an integrally formed annular structure, whereby the body 1 may be moved on the cable 18 by being passed through the outer circumference of the cable 18 to move to a suitable installation position.

[0046] In some embodiments, Figures 1 to 3 As shown, the stopper may further include a first connection matching structure 4 for plug-in matching of the first body 101 and the second body 102, and / or include a second connection matching structure 5 for snap-in matching of the first body 101 and the second body 102. That is, the first body 101 and the second body 102 may be connected together by plug-in or snap-in, or, in order to ensure the stability after the two are connected, a plug-in and snap-in joint matching connection method may also be adopted, thereby improving the disassembly and assembly efficiency of the first body 101 and the second body 102.

[0047] Among them, Figures 1 to 3As shown, the first connection matching structure 4 includes a first connection part 41 and a first matching part 42 that can be plugged and matched with the first connection part 41; the first body 101 is provided with one of the first connection part 41 and the first matching part 42, and the second body 102 is provided with the other of the first connection part 41 and the first matching part 42; for example, the first body 101 can be provided with the first connection part 41 at both ends, and correspondingly, the second body 102 can be provided with the first matching part 42 at both ends. When the first body 101 and the second body 102 need to be connected, the first connection parts 41 at both ends of the first body 101 and the first matching parts 42 at both ends of the second body 102 can be connected correspondingly. Alternatively, both the first body 101 and the second body 102 are provided with the first connection part 41 and the first matching part 42, and the first connection part 41 on the first body 101 and the first matching part 42 on the second body 102 are provided correspondingly, and the first matching part 42 on the first body 101 and the first connection part 41 on the second body 102 are provided correspondingly. For example, a first connecting portion 41 is provided at one end of the first body 101 and a first matching portion 42 is provided at the other end. When the first body 101 and the second body 102 are connected to each other, the end of the first body 101 having the first connecting portion 41 can be correspondingly connected to the end of the second body 102 having the first matching portion 42, and the end of the first body 101 having the first matching portion 42 can be correspondingly connected to the end of the second body 102 having the first connecting portion 41, so that the first body 101 and the second body 102 can be stably connected.

[0048] Specifically, Figures 1 to 3 As shown, the first connection portion 41 can be configured as one of a connection column 43 and a connection hole 44 that can be plugged and matched with the connection column 43, and the first matching portion 42 can be configured as the other of the connection column 43 and the connection hole 44. The first body 101 and the second body 102 can be connected together by plugging and matching the connection column 43 and the connection hole 44. When the first body 101 and the second body 102 are separated, the connection column 43 can be directly pulled out from the connection hole 44, which not only ensures the stability of the two after connection, but also ensures the simplicity of disassembly and assembly of the first body 101 and the second body 102, and improves the disassembly and assembly efficiency of the limiter.

[0049] In some embodiments of the present disclosure, Figures 1 to 3As shown, the second connection matching structure 5 may include a second connection portion 51 and a second matching portion 52 that can be snap-fitted with the second connection portion 51; the first body 101 is provided with one of the second connection portion 51 and the second matching portion 52, and the second body 102 is provided with the other of the second connection portion 51 and the second matching portion 52, that is, the first body 101 may be provided with the second connection portion 51, and the second body 102 may be provided with the second matching portion 52. When the first body 101 and the second body 102 are connected, the second connection portion 51 on the first body 101 can be snap-fitted with the second matching portion 52 on the second body 102, so that the limiting member can be sleeved on the outside of the cable 18; or, both the first body 101 and the second body 102 are provided with the second The connecting portion 51 and the second matching portion 52 are provided, and the second connecting portion 51 on the first body 101 and the second matching portion 52 on the second body 102 are provided correspondingly, and the second matching portion 52 on the first body 101 and the second connecting portion 51 on the second body 102 are provided correspondingly. For example, one end of the first body 101 and the second body 102 can be provided with the second connecting portion 51, and the other end can be provided with the second matching portion 52. When the first body 101 and the second body 102 are connected, one end of the first body 101 provided with the second connecting portion 51 is connected to one end of the second body 102 provided with the second matching portion 52, and one end of the second body 102 provided with the second connecting portion 51 is connected to one end of the first body 101 provided with the second matching portion 52.

[0050] Specifically, Figures 1 to 3 As shown, the second connecting portion 51 is configured as one of a block 53 and a slot 54 that can be engaged with the block 53, and the second engaging portion 52 is configured as the other of the block 53 and the slot 54. That is, the first body 101 and the second body 102 can be connected together through the engaging structure of the block 53 and the slot 54.

[0051] like Figures 1 to 3As shown, the present disclosure exemplarily shows the specific structure of the block 53 and the slot 54, the block 53 may include a block body 531 extending along the extension direction of the first body 101 and / or the second body 102 and a snap-in hole 532 arranged on the block body 531; the slot 54 may include a slot body 541 formed on the first body 101 and / or the second body 102 and a protrusion 542 arranged on the slot body 541 and capable of being snapped into the snap-in hole 532, so that at least part of the block body 531 fits into the slot body 541. When the second connecting portion 51 and the second matching portion 52 are connected, the protrusion 542 on the groove body 541 can be inserted into the locking hole 532 of the block body 531, so as to lock the first body 101 and the second body 102 together. The second connecting portion 51 and the second matching portion 52 have a simple structure and are easy to disassemble and assemble. No other connecting parts or fasteners independent of the body 1 are required to achieve a stable connection between the first body 101 and the second body 102, thereby improving the disassembly and assembly efficiency of the limiter.

[0052] like Figures 1 to 3 As shown, the present disclosure exemplarily shows a connection method between the first body 101 and the second body 102 when the first connecting matching structure 4 and the second connecting matching structure 5 are simultaneously provided on the first body 101. The first body 101 can be semi-circular, and one end of the first body 101 can be provided with a groove body 541 and a connecting column 43, wherein the connecting column 43 is protruding from the first body 101 along the extension direction of one end of the first body 101, and the groove body 541 is adjacent to the connecting column 43 and is located on the outside of the first body 101. The other end of the first body 101 can be provided with a connecting hole 44 and a block body 531, and the connecting hole 44 is extended to the inside of the first body 101 so that the connecting column 43 can be inserted into the connecting hole 44, and the block body 531 is provided. 1 is located outside the first body 101 and is arranged along the extension direction of the other end of the first body 101, so that the engaging hole 532 on the engaging block body 531 can engage with the protrusion 542; the structure of the second body 102 is the same as that of the first body 101. When the two need to be connected, only one of the first body 101 and the second body 102 needs to be turned 180°, so that the connecting column 43 on the first body 101 can be inserted into the connecting hole 44 on the second body 102, and the engaging block 53 on the first body 101 is engaged with the engaging groove 54. Based on this, the first body 101 and the second body 102 can be stably connected, and the structures on the first body 101 and the second body 102 can be simplified, thereby improving the disassembly and assembly efficiency of the limiting member.

[0053] It should be noted that the number of the first connection matching structures 4 and the second connection matching structures 5 can be adaptively adjusted according to specific usage scenarios, as long as the first body 101 and the second body 102 can be stably connected.

[0054] In some embodiments of the present disclosure, Figures 1 to 3 As shown, a limiting protrusion 3 extending toward one side of the axis of the limiting cavity 2 is provided inside the limiting cavity 2, and at least a part of the limiting protrusion 3 can fit with the cable 18. The limiting protrusion 3 can make the connection between the main body 1 and the cable 18 tighter after being sleeved on the outside of the cable 18, so that when the cable 18 deflects or bends, the limiting protrusion 3 can reduce or even prevent the deformation of the cable 18, thereby avoiding the situation where the sealing ring 11 is unevenly stressed and misaligned. The limiting protrusion 3 can be arranged in any manner, for example, the limiting protrusion 3 can be arranged around the inner wall of the limiting cavity 2, or arranged along the extension direction of the limiting cavity 2, or a combination of the two arrangements is adopted, which is not specifically limited in the present disclosure.

[0055] In some embodiments of the present disclosure, Figures 1 to 3 As shown, the body 1 also includes a connection structure 6, which is used to be detachably connected to the housing 8 of the connector plug. When the cable 18 is subjected to axial force, since the housing 8 is relatively fixed and the body 1 of the limiter is connected to both the cable 18 and the housing 8, the body 1 can prevent the cable 18 from axial movement, thereby avoiding poor contact of the connector.

[0056] Among them, Figures 1 to 3 As shown, the connection structure 6 may include a connection groove 61 and a connection block 62 arranged on the outer surface of the main body 1; one end of the connection block 62 is arranged in the connection groove 61, and the other end is extended to the outside of the connection groove 61 until at least part of the projection of the connection block 62 in the first direction A is located outside the connection groove 61; the connection block 62 is configured so that when the other end of the connection block 62 is subjected to an external force toward one side of the connection groove 61, it can move toward the side of the connection groove 61, so that the projection of the connection block 62 on the first side is located in the connection groove 61. That is, the connecting block 62 may include a connecting end connected to the connecting groove 61 and a free end that has no connection relationship with other structures. Generally, the projection of the free end of the connecting block 62 in the first direction A is located outside the connecting groove 61. When the main body 1 needs to be connected to the shell 8, an external force toward the connecting groove 61 can be applied to the free end so that the free end is also located in the connecting groove 61. At this time, the connecting block 62 can be snapped into the matching structure 13 of the shell 8, thereby connecting the main body 1 to the shell 8. The matching structure 13 of the shell 8 can be constructed as, for example, a hole structure that can be snapped into the connecting block 62. In this way, when the external force is stopped being applied to the free end, the free end will move in the direction away from the connecting groove 61 and enter the hole structure, thereby realizing the snap connection between the main body 1 and the shell 8.

[0057] In some embodiments of the present disclosure, Figures 1 to 3As shown, the main body 1 may further include a weight reducing groove 7, which may be disposed at any position of the main body 1 as needed to reduce the mass of the limiting member. For example, the weight reducing groove 7 may be disposed between the inner wall and the outer wall of the main body 1 and along the extension direction of the main body 1, but the present disclosure is not limited thereto.

[0058] In the second aspect of the present disclosure, Figures 4 to 9 As shown, a connector plug is provided, including a shell 8, a terminal cable assembly, an end cover 12 and the above-mentioned limit member, wherein the shell 8 includes a plurality of sockets 9 that pass through the shell 8 and are arranged at intervals; the terminal cable assembly is used to connect the cable 18, including a sealing ring 11 that is sleeved on the outer peripheral side of the cable 18 and abuts against the shell 8, and a plurality of terminal cable assemblies are inserted into the socket 9; the end cover 12 is detachably connected to the shell 8 to shield at least part of the socket 9; the limit member is arranged between the end cover 12 and the sealing ring 11. Specifically, in addition to the sealing ring 11, the terminal cable assembly may also include a terminal 15, a shielding crimping ring 16, and a shielding support ring 17. After the terminal 15 is connected to the cable 18, the shielding support ring 17 will be sleeved on the outer peripheral side of the cable 18, and the shielding crimping ring 16 will be sleeved on the outer peripheral side of the shielding support ring 17 and can be abutted against the inner wall of the shell 8 after the terminal cable assembly is installed into the socket 9 of the shell 8. The sealing ring 11 is sleeved on the outer peripheral side of the cable 18 and abuts against the shell 8 to seal the connector plug, and the sealing ring 11 is located between the shielding support ring 17 and the limit member. Finally, the end cover 12 is connected to the shell 8 to complete the assembly of the connector plug.

[0059] In some embodiments of the present disclosure, Figure 6 As shown, a matching structure 13 can be provided on the outer peripheral side of the socket 9 to engage the limit member, so that no other separate connecting parts are needed when connecting the limit member and the socket 9 of the shell 8. This facilitates the disassembly of the limit member and the shell 8, thereby improving the disassembly and assembly efficiency and maintenance efficiency of the connector shell 8.

[0060] The matching structure 13 may be configured as a first positioning hole 1301 , so that the connection block 62 of the connection structure 6 of the limiting member may be inserted into the first positioning hole 1301 , thereby achieving connection between the limiting member and the housing 8 .

[0061] In some embodiments, Figure 6 As shown, a positioning protrusion 14 is also provided on the outer peripheral side of the socket 9; the end cover 12 includes a second positioning hole 1201, and the end cover 12 is sleeved on at least part of the outer peripheral side of the housing 8 so that the positioning protrusion 14 is snapped into the second positioning hole 1201. That is, the end cover 12 and the socket 9 of the housing 8 can also be connected by snapping, which is convenient for the disassembly and assembly of the two.

[0062] It should be noted that the end cover 12 can be an integrated end cover, that is, one end cover 12 can directly cover multiple sockets 9 and be snap-fitted with the sockets 9 to achieve sealing of one end of the connector plug, or, as Figure 7 As shown, the end cover 12 can also be a split end cover, that is, each end cover 12 can be individually connected to each socket 9, and each end cover 12 can be provided with a notch to avoid mutual interference between the end covers 12, so as to achieve sealing operation on one end of the connector plug. In this way, the end cover 12 can be installed on the outer peripheral side of the cable 18 first, or it can be installed after the terminal cable assembly is connected to the shell 8. Compared with the integrated end cover, the split end cover does not need to be installed on the cable 18 first, which improves the flexibility of the connector plug when disassembling and assembling.

[0063] In addition, the inner wall of the socket 9 can be configured as a stepped hole to facilitate the insertion of the terminal cable assembly and the stopper into the socket 9, thereby ensuring the stability of the connection.

[0064] In some embodiments, at least a portion of the outer wall of the main body 1 abuts against the inner surface of the socket 9, so that when the cable 18 deflects or bends, the shell 8 can prevent the limiter from moving radially with the cable 18, thereby further ensuring the stability of the cable 18 and the sealing ring 11 in the shell 8, and ensuring the sealing of the sealing ring 11.

[0065] The third aspect of the present disclosure provides a connector, including a plug and a socket, wherein the plug adopts the above connector plug. It should be noted that the connector has all the beneficial effects of the above connector plug, and the present disclosure is no longer limited here.

[0066] A fourth aspect of the present disclosure provides a vehicle, comprising the above connector. It should be noted that the vehicle has all the beneficial effects of the above connector, and the present disclosure is no longer limited thereto.

[0067] In summary, the present disclosure exemplarily illustrates the assembly and use process of the limiter and the connector plug.

[0068] The end of the cable 18 can be first connected to the terminal 15, and then the shielding support ring 17 is sleeved on the outer peripheral side of the cable 18, and the shielding crimping ring 16 is sleeved on the outer peripheral side of the shielding support ring 17, so that after the terminal cable assembly is inserted into the socket 9 of the shell 8, the outer wall of the shielding crimping ring 16 can be against the inner wall of the socket 9. At this time, the first body 101 and the second body 102 can be sleeved on both sides of the cable 18, and are connected together through the plug-in method of the connecting hole 44 and the connecting column 43 and / or the card block 53 and the card slot 54 to form the body 1. As a result, the cable 18 will pass through the limiting cavity 2 of the body 1, and the outer side wall of the body 1 will be against the inner surface of the socket 9 and pass through the connection. The connecting block 62 is inserted into the first positioning hole 1301, and finally the end cover 12 can also be engaged with the positioning protrusion 14 on the socket 9 through the second positioning hole 1201 to complete the assembly of the connector plug. In this way, when the cable 18 outside the connector plug is deflected or bent, the limiter can limit the radial movement distance of the cable 18 inside the connector plug to a certain extent, and can even avoid the radial movement of the cable 18 inside the connector plug. Therefore, the limiter can reduce at least part of the external force exerted by the cable 18 on the sealing ring 11, thereby preventing the sealing ring 11 from being dislocated due to the external force generated by the displacement or bending of the cable 18, thereby ensuring the sealing of the connector plug.

[0069] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0071] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
