[0052] The disclosure below provides many different embodiments or examples to realize different structures of the present disclosure. In order to simplify the disclosure of the present disclosure, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present disclosure.

In addition, the present disclosure provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0054] Please also read Figure 1 and Figure 2 , an embodiment of the present disclosure provides a cable connector 100, where the cable is, for example, a power cable, and the power supply can be specifically applied to input and output power supply devices of wireless AAU / RRU, energy, wired, etc. The device to be connected is, for example, a device to be powered, such as a wireless base station. In this case, the cable connector 100 provided in the embodiment of the present disclosure is used as a power cable connector, which is used to electrically connect the power cable to the device to be powered, and specifically can be electrically connected to the circuit board of the device to be powered to meet the power supply requirements. Of course, in actual applications, the cable connector 100 is also applied to other cables, such as data cable cables, and the cable connector 100 can be applicable to cables with a variety of different numbers of core wires and different wire diameters.

[0055] The cable connector 100 includes a plug 2 for electrically connecting the cable 1 to a device to be connected (not shown in the figure), and an adapter 3 for electrically connecting the plug 2 to the device to be connected. It should be noted that, according to specific needs, the plug 2 can be used to directly connect to the device to be connected, and the adapter 3 may not be provided at this time; or, the adapter 3 can also be used to electrically connect the plug 2 to the device to be connected, both of which can realize the electrical connection between the cable 1 and the device to be connected. The adapter 3 is generally suitable for electrically connecting to the circuit board inside the device to be connected. Optionally, the plug 2 and the adapter 3 are connected by plugging.

[0056] Please also read Figures 3 to 5, the plug 2 includes an inner core, which includes an inner core body 21 and a locking wire unit arranged on the inner core body 21, and the locking wire unit is used to lock the end of the cable 1 to the inner core body 21. Specifically, the locking wire unit includes a plurality of locking wire assemblies, and the plurality of locking wire assemblies are used to lock the end of the cable 1 to the inner core body 21 to prevent the cable 1 from escaping from the inner core, so that multiple locking of the cable 1 can be achieved, thereby ensuring the long-term and reliable locking effect. On this basis, the plurality of locking wire assemblies are configured so that a part of the plurality of locking wire assemblies blocks at least one locking wire assembly in another part when not locked in place, so that at least one locking wire assembly in another part cannot lock the end of the cable. In other words, if one or more locking wire assemblies are not locked in place, they will block at least one of the other locking wire assemblies from achieving the locking action.

[0057] The disclosed embodiment adopts multiple locking wire assemblies to lock the end of the cable to the inner core body 21, so as to achieve multiple locking of the cable 1, thereby ensuring that the locking effect is reliable for a long time. On this basis, by making a part of the multiple locking wire assemblies block at least one locking wire assembly in another part when not locked in place, so that at least one locking wire assembly in another part cannot lock the end of the cable 1, it can be ensured that the locking operation of at least one locking assembly in another part can be performed only after a part of the locking assemblies is locked in place, that is, the installation sequence of the connector is restricted, and the effect of fool-proof and error-proof operation is achieved, and the engineering fault tolerance of the cable connector 100 is improved. At the same time, because the probability of operating errors is reduced, the problem of poor assembly of the cable connector 100 can be reduced or even avoided. In the case where the cable connector 100 is applied to a power connector, the risk of severe heating caused by excessive contact resistance inside the connector can be reduced, thereby ensuring the performance and life of the power connector and avoiding serious accidents such as circuit failure or equipment burning.

[0058] It should be noted that the blocking wire locking assembly may be one or more, and the blocked wire locking assembly may be one or more, and the blocking wire locking assembly may block one other wire locking assembly or multiple other wire locking assemblies at the same time. Multiple blocking wire locking assemblies may also block one or more other wire locking assemblies together.

[0059] It should also be noted that the wire locking methods of the multiple wire locking assemblies can be the same method or a combination of multiple different methods.

[0060] In some embodiments, the plurality of wire locking assemblies include at least one first wire locking assembly and at least one second wire locking assembly, and the first wire locking assembly and the second wire locking assembly have different wire locking methods. The following takes the example of one first wire locking assembly and one second wire locking assembly as examples to describe the specific implementation methods of the two in detail. Of course, in practical applications, the specific structures of the first wire locking assembly and the second wire locking assembly are also applicable to the case of other numbers of wire locking assemblies.

[0061] For details, please refer to Figures 3 to 5 The plurality of wire locking assemblies include a first wire locking assembly 211 and a second wire locking assembly 212. The first wire locking assembly 211 and the second wire locking assembly 212 are both used to lock the end of the cable 1 to the inner core body 21 to prevent the cable 1 from escaping from the inner core. The first wire locking assembly 211 and the second wire locking assembly 212 are configured so that the first wire locking assembly 211 blocks the second wire locking assembly 212 when it is not locked in place, so that the second wire locking assembly 212 cannot lock the end of the cable.

[0062] Specifically, the relative position of the first locking wire assembly 211 to the inner core body 21 when locked in place is different from the relative position to the inner core body 21 when not locked in place, and the difference in position can be used to switch the second locking wire assembly 212 between the unblocked and blocked states. Figure 4 When the first locking wire assembly 211 is not locked in place, a portion of it will protrude from the outer surface of the inner core body 21, and the protruding portion can block the second locking wire assembly 212, so that the second locking wire assembly 212 cannot reach the position of locking the cable end. Figure 5 , the second wire locking component 212 can only lock the cable end when it is located flush with or lower than the outer surface of the inner core body 21. Specifically, a space for accommodating the first wire locking component 211 and the second wire locking component 212 is provided inside the inner core body 21. The space has an opening, and the first wire locking component 211 and the second wire locking component 212 can protrude from the outer surface of the inner core body 21 through the opening. Of course, in actual applications, the first wire locking component 211 and the second wire locking component 212 can also adopt other methods to achieve that the first wire locking component 211 blocks the second wire locking component 212 when it is not locked in place, so that the second wire locking component 212 cannot lock the end of the cable, which all belong to the protection scope of the embodiments of the present disclosure.

[0063] The disclosed embodiment adopts two locking wire components, namely the first locking wire component 211 and the second locking wire component 212, to lock the end of the cable to the inner core body 21, so as to achieve double locking of the cable 1, thereby ensuring that the locking effect is reliable for a long time. On this basis, by making the first locking wire component 211 block the second locking wire component 212 when it is not locked in place, so that the second locking wire component 212 cannot lock the end of the cable 1, it can be ensured that the locking operation of the second locking wire component 212 can be performed only after the first locking wire component 211 is locked in place, that is, the installation sequence of the connector is restricted, and the effect of foolproof and error-proof operation is achieved, and the engineering fault tolerance of the cable connector 100 is improved. At the same time, because the probability of operating errors is reduced, the problem of poor assembly of the cable connector 100 can be reduced or even avoided. In the case where the cable connector 100 is applied to a power connector, the risk of severe heating caused by excessive contact resistance inside the connector can be reduced, thereby ensuring the performance and life of the power connector and avoiding serious accidents such as circuit failure or equipment burning.

[0064] In some embodiments, Figure 3 As shown, the plug 2 further includes a sheath 22, in which the inner core (i.e., the inner core body 21) is inserted; the sheath 22 is made of, for example, plastic. The second locking wire assembly 212 is configured to block the inner core body 21 when the end of the cable 1 is not locked, so that the inner core body 21 cannot be inserted into a designated position in the sheath 22.

[0065] Specifically, see Figure 4 When the first locking wire component 211 is not locked in place, a part of it will protrude from the outer surface of the inner core body 21, and the protruding part can block the second locking wire component 212, so that the second locking wire component 212 cannot reach the position of locking the cable end. At this time, the second locking wire component 212 is at least partially tilted relative to the outer surface of the inner core body 21, and the tilted part will block the inner core body 21, so that the inner core body 21 cannot be inserted into the specified position in the sheath 22. Optionally, as Figure 5 As shown, only when the second locking wire assembly 212 is lower than or flush with the outer surface of the inner core body 21 can the inner core body 21 be inserted into the designated position in the sheath 22, for example, the inner core body 21 is completely inserted into the sheath 22. By adopting the above design, on the basis of limiting the installation order of the first locking wire assembly 211 and the second locking wire assembly 212, the installation order of the second locking wire assembly 212 and the sheath 22 can be further limited, thereby further improving the effect of foolproofing and error-proofing the operation, and improving the engineering fault tolerance of the cable connector 100.

[0066] In some embodiments, see Figures 1 to 5In the case where the cable connector 100 further includes an adapter 3, the cable connector 100 further includes an adapter locking assembly 4, which is used to lock the adapter 3 to the sheath 22. With the help of the adapter locking assembly 4, the adapter 3 can be locked to the sheath 22 while preventing the inner core body 21 from coming out of the sheath 22, thereby ensuring a long-term and reliable locking effect. It is understandable that when the inner core body 21 is not inserted into the specified position in the sheath 22, the adapter locking assembly 4 cannot lock the adapter 3 to the sheath 22.

[0067] The adapter locking assembly 4 that realizes the above functions can have various structures, for example, see Figures 1 to 4 The adapter locking assembly 4 includes an adjustable wrench 41, a limiting component 31 and a locking button 42, wherein the limiting component 31 is disposed on the adapter 3, the adjustable wrench 41 is rotatably connected to the sheath 22, for example, by a rotating shaft 43, and the adjustable wrench 41 can be rotated to a closed position (such as a position where the adjustable wrench 41 contacts the outer surface of the sheath 22) Figure 1 , Figure 2 position), or rotate from the closed position in a direction away from the outer surface of the sheath 22 to the expanded position (such as Figure 3 , Figure 4 and, a limiting structure is provided on the movable wrench 41, and when the movable wrench 41 is in the closed position, the limiting structure cooperates with the limiting component 31 to limit and fix the adapter 3 and the sleeve 22; when the movable wrench 41 is in the expanded position, the limiting structure is released from the limiting component 31, and the adapter 3 can be separated from the sleeve 22.

[0068] Specifically, the limiting structure is, for example, an arc-shaped through hole 411 and a blocking portion (not shown) that are provided on the movable wrench 41. Figure 1 As shown, the above-mentioned limiting component 31 is a limiting protrusion arranged on the outer surface of the adapter 3, and the limiting protrusion is located in the arc-shaped through hole 411, and can move relatively along the extension direction of the arc-shaped through hole 411 when the movable wrench 41 rotates; the blocking part is used to limit the limiting protrusion in the arc-shaped through hole 411 when the movable wrench 41 is in the closed position, so that the limiting protrusion cannot be moved out of the arc-shaped through hole 411, thereby realizing the limiting fixation of the adapter and the sheath 22. The blocking part is, for example, a blocking protrusion formed on one side of the movable wrench 41 adjacent to the limiting component 31. In addition, when the movable wrench 41 is in the unfolded position, the blocking part releases the restriction on the limiting protrusion, and the limiting protrusion can be moved out of the arc-shaped through hole 411, thereby realizing the separation of the adapter 3 and the sheath 22. The movable wrench 41 is also provided with a button matching portion 412. The locking button 42 is movably provided on the sheath 22 and can be moved to a locking position and an unlocking position. When the movable wrench 41 is in the closed position, the locking button 42 is moved to the locking position (such as Figure 2The locking button 42 can be matched with the button matching portion 412 on the movable wrench 41 to limit and fix the movable wrench 41. At this time, the movable wrench 41 cannot be rotated; by moving the locking button 42 to the non-locking position (such as Figure 4 The locking button 42 is in the locking position (such as the locking position), so that the locking button 42 and the button matching portion 412 are released, and the movable wrench 41 can be rotated. The button matching portion 412 is, for example, a slot formed on the movable wrench 41, and the locking button 42 is provided with a clamping member. The clamping member is Figure 2 It should be noted that the above-mentioned limiting structure set on the movable wrench 41 can also adopt other structures, as long as it can achieve the above-mentioned function, it belongs to the protection scope of the embodiment of the present disclosure.

[0069] In some embodiments, please refer to Figures 6 to 8 The inner core body 21 includes an inner core shell 213 and a bearing assembly 214 inserted in the inner core shell 213, and the inner core shell 213 is made of plastic material, for example. The bearing assembly 214 can be at least partially located in the inner core shell 213, and the bearing assembly 214 is used to accommodate the first locking wire assembly 211 and the second locking wire assembly 212, as well as the end of the cable 1. The inner core shell 213 can not only protect the bearing assembly 214 and various parts thereon, but also play a role in limiting and fixing the components on the bearing assembly 214 to prevent these components from escaping from the bearing assembly 214, thereby improving the structural stability and reliability. In addition, an opening is provided on the inner core shell 213 that is connected to the space for accommodating the first locking wire assembly 211 and the second locking wire assembly 212, so that the first locking wire assembly 211 and the second locking wire assembly 212 can protrude from the outer surface of the inner core shell 213 from the opening. In this case, when the first locking wire assembly 211 is not locked in place, it blocks the second locking wire assembly 212, so that the second locking wire assembly 212 cannot reach the position of locking the cable end. At this time, the second locking wire assembly 212 is at least partially tilted relative to the outer surface of the inner core outer shell 213, and the tilted portion blocks the inner core outer shell 213, so that the inner core outer shell 213 cannot be inserted into the specified position in the sheath 22. Only when the second locking wire assembly 212 is lower than or flush with the outer surface of the inner core outer shell 213 can the inner core outer shell 213 be inserted into the specified position in the sheath 22.

[0070] In some embodiments, please refer to Fig. 9 and Fig.10 The first locking wire assembly 211 includes a mounting component 211a and a locking wire component 211b. The mounting component 211a is made of metal, for example. The mounting component 211a is connected to the inner core body 21, and the mounting component 211a has a receiving cavity 2111, which is used to receive the conductive exposed portion 111 of the cable end. Figure 6 As shown, the conductive exposed portion 111 is the conductive portion of the core wire of the cable 1 exposed after the insulation layer is stripped. In the case where the cable 1 is a power cable, the end of the power cable includes a positive branch 11 and a negative branch 12, that is, the positive core wire and the negative core wire of the power cable are forked at the end to form two branches, and the end of each branch is stripped of the insulation layer to form a conductive exposed portion 111. In this case, Fig. 9 As shown, there are two installation components 211 a and two wire locking components 211 b , and the two accommodating cavities 2111 are used to accommodate the conductive exposed parts 111 of the positive branch 11 and the negative branch 12 respectively.

[0071] The wire locking component 211b is connected to the installation component 211a, and is used to lock the conductive exposed portion 111 in the accommodating cavity 2111, and when not locked in place, blocks the second wire locking component 212 so that the second wire locking component 212 cannot lock the conductive exposed portion 111. By using the accommodating cavity 2111 to accommodate the conductive exposed portion 111 at the end of the cable, the conductive exposed portion 111 can be limited. On this basis, the conductive exposed portion 111 is locked in the accommodating cavity 2111 using the locking component 211b, which can improve the locking firmness and reliability, and can also limit the length of the conductive exposed portion 111 at the end of the cable. In actual applications, the operator only needs to strip the insulation layer of the cable according to the size of the accommodating cavity 2111 to obtain the above-mentioned conductive exposed portion 111, thereby avoiding problems such as "the insulation layer of the cable is stripped too short" and "the cables are of uneven length" during operation, thereby achieving the effect of preventing stupidity and error in operation, and improving the engineering fault tolerance of the cable connector 100.

[0072] The locking wire component 211b can press the conductive exposed portion 111 tightly into the accommodating cavity 2111. The locking wire component 211b that realizes this function can have various structures, for example, Fig.11 As shown, the wire locking component 211b includes a wire locking bracket 2112 and a locking screw 2113. The wire locking bracket 2112 is connected to the mounting component 211a, and a threaded hole 2112a communicating with the accommodating cavity 2111 is provided on the wire locking bracket 2112; the screw head 2113a of the locking screw 2113 is provided on the side of the wire locking bracket 2112 away from the accommodating cavity 2111 (for example, Fig.10 ), such as Fig.10As shown, the stud 2113b of the locking screw 2113 is threadedly matched with the threaded hole 2112a, and one end of the stud 2113b extends into the accommodating cavity 2111, and when the locking screw 2113 is screwed in place, the conductive exposed portion 111 is pressed into the accommodating cavity 2111. In practical applications, locking screws 2113 of different lengths can be selected according to different wire diameters of cables to ensure that the conductive exposed portion 111 is pressed into the accommodating cavity 2111 when the locking screw 2113 is screwed in place, that is, a locking screw 2113 of a specific length is correspondingly locked to a cable of a wire diameter, so that it can be applied to cables of multiple different wire diameters.

[0073] On this basis, the locking screw 2113 can be configured to block the second locking wire assembly 212 when it is not locked in place, so that the second locking wire assembly 212 cannot lock the conductive exposed portion 111. For example, when the locking screw 2113 is locked, if the locking screw 2113 is not tightened due to insufficient locking force, or if the locking screw 2113 is not locked, it is considered that the locking screw 2113 is not locked in place. At this time, the screw head 2113a of the locking screw 2113, for example, protrudes from the outer surface of the inner core shell 213, blocking the second locking wire assembly 212 from pressing down, so that the second locking wire assembly 212 cannot lock the conductive exposed portion 111. Specifically, by designing the position, size and other parameters of the screw head 2113a of the above-mentioned locking screw 2113, as well as the position, structure and size and other parameters of the above-mentioned second locking wire assembly 212, the purpose of enabling the screw head 2113a of the locking screw 2113 to block the second locking wire assembly 212 when it is not locked in place can be achieved.

[0074] In some embodiments, Fig.10 As shown, the above-mentioned installation component 211a includes a first cavity wall 2111a, a second cavity wall 2111b and a third cavity wall 2111c that contain the cavity 2111, and each of the first cavity wall 2111a, the second cavity wall 2111b and the third cavity wall 2111c is connected and perpendicular to each other; wherein the first cavity wall 2111a and the second cavity wall 2111b are both located on the peripheral side of the conductive exposed part 111, and the third cavity wall 2111c is located on the end side of the conductive exposed part 111; the wire locking bracket 2112 includes a frame body, and the first cavity wall 2111a, the second cavity wall 2111b and the conductive exposed part 111 all pass through the frame body; the threaded hole 2112a is set through the frame body, and is located on the side opposite to the first cavity wall 2111a or the second cavity wall 2111b, for example Fig.10As shown, the threaded hole 2112a is located on the side opposite to the second cavity wall 2111b (i.e., the upper side of the frame). The first cavity wall 2111a, the second cavity wall 2111b, and the third cavity wall 2111c are enclosed to form a receiving cavity 2111 for receiving the conductive exposed portion 111. Optionally, when the threaded hole 2112a is located on the opposite side of the second cavity wall 2111b, the present embodiment further uses a fixing member 214j (described in detail later) of the inner core body 21 to enclose the first cavity wall 2111a, the second cavity wall 2111b, and the third cavity wall 2111c on the opposite side of the first cavity wall 2111a to form the receiving cavity 2111.

[0075] It is easy to understand that the accommodating chamber 2111 has an opening on the opposite side of the third chamber wall 2111c, so that the conductive exposed part 111 of the cable can pass through the opening to enter the accommodating chamber 2111, and pass through the space 2112b surrounded by the frame in the process of passing through the accommodating chamber 2111. The accommodating chamber 2111 also has an opening on the opposite side of the second chamber wall 2111b, so that the locking screw 2113 can pass through the threaded hole 2112a and extend into the accommodating chamber 2111, so as to press the conductive exposed part 111 into the accommodating chamber 2111. The wire locking bracket 2112 is not only easy to install, but also can limit the conductive exposed part 111, thereby improving the locking firmness and reliability.

[0076] There are many ways to enable the screw head 2113a of the locking screw 2113 to block the second locking wire assembly 212 when it is not locked in place, for example, Fig. 9 As shown, a through hole 214d is provided at the position of the inner core body 21 corresponding to the threaded hole 2112a, one end of the through hole 214d is connected to the threaded hole 2112a, and the other end is connected to the outer surface of the inner core body 21 (i.e., the outer surface of the inner core shell 213). It is easy to understand that the through hole 214d is formed at the corresponding position of the inner core shell 213 and the bearing assembly 214 inserted in the inner core shell 213. The screw head 2113a is located in the through hole 214d when the locking screw 2113 is screwed in place, and at least partially located outside the through hole 214d when the locking screw 2113 is not screwed in place, so as to block the second locking wire assembly 212 so that the second locking wire assembly 212 cannot lock the cable end.

[0077] In some embodiments, Fig.10 and Fig.11As shown, the wire locking component 211b also includes a baffle 2114, which includes two mutually perpendicular flat portions (2114a, 2114b), wherein one of the flat portions 2114a is arranged in the space 2112b enclosed by the frame, and is located between the stud 2113b of the locking screw 2113 and the conductive exposed portion 111, and is used to increase the contact area between the locking screw 2113 and the conductive exposed portion 111, to avoid the locking screw 2113 and the conductive exposed portion 111 being insecurely contacted, thereby improving the locking stability, and at the same time, by arranging the flat portion 2114a between the stud 2113b of the locking screw 2113 and the conductive exposed portion 111, it can be ensured that the conductive exposed portions 111 of cables with a variety of different wire diameters can be locked, thereby being suitable for cables with a variety of different wire diameters. Another flat plate portion 2114b of the baffle 2114 is located outside the space 2112b enclosed by the frame, and is located on the side of the frame away from the third cavity wall 2111c, and is used to block the gap between the stud 2113b and the frame. By using the flat plate portion 2114b located outside the space 2112b enclosed by the frame to block the gap between the stud 2113b and the frame, it is possible to prevent the conductive exposed portion 111 of the cable from being inserted into the gap between the stud 2113b and the frame when passing through the space 2112b enclosed by the frame, thereby causing the locking screw 2113 to fail to press the conductive exposed portion 111, resulting in locking failure. Optionally, when the stud 2113b of the locking screw 2113 is locked in place, it is riveted to the flat plate portion 2114a located between the stud 2113b of the locking screw 2113 and the conductive exposed portion 111, so that the flat plate portion 2114a can be limited and fixed.

[0078] In some embodiments, Fig.10As shown, the mounting component 211a also includes a first power pin 2115, one end of which is located on the side of the third cavity wall 2111c away from the accommodating cavity 2111, and is connected to the third cavity wall 2111c, and is electrically conductive; the first cavity wall 2111a, the second cavity wall 2111b and the third cavity wall 2111c are all electrically conductive with the conductive exposed portion 111, so that the first power pin 2115 can be electrically conductive with the conductive exposed portion 111 through the first cavity wall 2111a, the second cavity wall 2111b and the third cavity wall 2111c, and is used as a lead-out terminal of the cable. Optionally, the first power pin 2115 is connected to the third cavity wall 2111c as a whole. In the case where the cable connector 100 also includes an adapter 3 for electrically connecting the plug 2 to the device to be connected, the adapter 3 includes a second power pin (not shown in the figure), and the other end of the first power pin 2115 is electrically connected to the second power pin. The electrical connection method of the second power pin and the first power pin 2115 is, for example, that one end of the second power pin and the first power pin 2115 is provided with a slot, and the other end is provided with a plug-in component, and the plug-in component matches the slot and is electrically conductive. The matching method of the plug-in component and the slot is, for example, a snap-on connection, a plug-in connection, or an interference fit, etc., as long as a good conductive effect can be achieved, and the embodiments of the present disclosure have no particular restrictions on this. In addition, if Figure 2 As shown, taking cable 1 as a power cable and the device to be connected as a device to be powered as an example, the adapter 3 also includes two jumper pieces 32 for electrically connecting to the circuit board of the device to be powered, and the two jumper pieces 32 are electrically connected to the two second power pins respectively, so as to realize the electrical connection between the second power pins and the circuit board. Optionally, the adapter 3 also includes a flange 33 for fixedly connecting to the mounting panel of the device to be powered, and the mounting panel has a cavity, and the adapter 3 is located Figure 2 The left side portion of the middle flange 33 is arranged in the cavity, located Figure 2 The right side of the middle flange 33 is located outside the cavity, and the flange 33 is fixedly connected to the cavity by bolts or screws.

[0079] In some embodiments, taking the cable as a power cable as an example, Figure 6As shown, the end of the power cable includes a positive branch 11 and a negative branch 12. In this case, there are two mounting components 211a, and the accommodating cavities 2111 on the two mounting components 211a are used to respectively accommodate the conductive exposed portions 111 of the ends of the positive branch 11 and the negative branch 12; there are two locking wire components 211b, and the two locking wire components 211b are respectively connected to the two mounting components 211a, and are used to lock the two conductive exposed portions 111 in the two accommodating cavities 2111; there are two second power pins, and the other ends of the two first power pins 2115 are respectively electrically connected to the two second power pins. Thus, the first power pin 2115 can be electrically connected to the conductive exposed portions 111 of the positive branch 11 and the negative branch 12, respectively, and are used as the positive lead-out terminal and the negative lead-out terminal of the cable, respectively. Of course, in actual applications, the cable may also be other types of cables, such as a data cable, and the end of the cable may not be branched, or may include more than three branches. In this case, the number of mounting components 211a, locking components 211b and second power pins is the same as the number of branches, and they are connected one-to-one.

[0080] In order to enable the first locking wire assembly 211 (for example, the screw head 2113a of the locking screw 2113) to block the second locking wire assembly 212 when it is not locked in place, the second locking wire assembly 212 can have various structures, for example, Fig. 9 and Fig.12 As shown, the second locking wire assembly 212 is movably connected to the inner core body 21 (i.e., the bearing assembly 214), and the second locking wire assembly 212 is provided with a blocked portion 212a and a first matching portion 212b, and the inner core body 21 (i.e., the bearing assembly 214) is provided with a second matching portion 214e; the first matching portion 212b matches with the second matching portion 214e (as shown in FIG. Fig. 9 ), the second locking wire assembly 212 and the inner core body 21 (i.e., the bearing assembly 214) are locked with each other, and the second locking wire assembly 212 locks the cable end; and when the first locking wire assembly 211 is locked in place, the second locking wire assembly 212 can move to a position where the first matching portion 212b matches the second matching portion 214e, for example, to a space on the inner core shell 213 for accommodating the second locking wire assembly 212 (as shown in FIG. Figure 6 As shown in FIG. 2 ), when the first locking wire assembly 211 is not locked in place, the blocked portion 212a is blocked by the first locking wire assembly 211 (ie, the screw head 2113a) (as shown in FIG. 2 ). Figure 4As shown in the figure, the second lock wire assembly 212 cannot move to the position where the first matching portion 212b and the second matching portion 214e match, for example, the blocked portion 212a is tilted relative to the outer surface of the inner core shell 213, and the tilted portion will block the inner core shell 213, so that the inner core shell 213 cannot be inserted into the specified position in the sheath 22. Optionally, one of the first matching portion 212b and the second matching portion 214e is a snap-fit ​​piece, and the other is a slot, and the snap-fit ​​piece and the slot are snap-fitted to achieve the locking of the second lock wire assembly 212 and the inner core body 21. Of course, in actual applications, the first matching portion 212b and the second matching portion 214e can also be matched in other detachable ways, and the embodiments of the present disclosure have no particular restrictions on this.

[0081] Specifically, the screw head 2113a of the locking screw 2113 is located in the above-mentioned through hole 214d when the locking screw 2113 is tightened into place. At this time, the screw head 2113a will not block the second locking wire assembly 212 (i.e., the blocked portion 212a). The second locking wire assembly 212 can move to a position where the first matching portion 212b matches the second matching portion 214e, thereby locking the second locking wire assembly 212 and the inner core body 21 (i.e., the load-bearing assembly 214) with each other, and the second locking wire assembly 212 locks the cable end. When the locking screw 2113 is not screwed into place, at least part of it is located outside the through hole 214d. At this time, the part of the screw head 2113a located outside the through hole 214d will block the second locking wire assembly 212 (i.e., the blocked portion 212a), so that the second locking wire assembly 212 cannot move to the position where the first matching portion 212b matches the second matching portion 214e, so that the second locking wire assembly 212 and the inner core body 21 cannot be locked, and the second locking wire assembly 212 cannot lock the cable end. In practical applications, the position, structure, size and other parameters of the blocked portion 212a can be designed to achieve the purpose of enabling the screw head 2113a of the locking screw 2113 to block the blocked portion 212a when it is not locked into place.

[0082] Further optionally, the blocked portion 212a abuts against the first wire locking assembly 211 (i.e., the screw head 2113a), and when the first wire locking assembly 211 (i.e., the locking screw 2113) is screwed into place, the blocked portion 212a is lower than or flush with the outer surface of the inner core outer shell 213, and when the first wire locking assembly 211 (i.e., the locking screw 2113) is not screwed into place, the blocked portion 212a protrudes from the outer surface of the inner core outer shell 213. In this way, when the first wire locking assembly 211 is screwed into place, by making the blocked portion 212a lower than or flush with the outer surface of the inner core outer shell 213, the inner core outer shell 213 can be smoothly inserted into the designated position in the sheath 22. When the first locking wire assembly 211 (i.e., the locking screw 2113) is not tightened into place, since the blocked portion 212a protrudes from the outer surface of the inner core outer shell 213, the blocked portion 212a will block the inner core body 21 from being inserted into the designated position in the sheath 22. This can further restrict the installation sequence of the second locking wire assembly 212 and the sheath 22 on the basis of restricting the installation sequence of the first locking wire assembly 211 and the second locking wire assembly 212, thereby further improving the effect of preventing foolishness and errors in operation and enhancing the engineering fault tolerance of the cable connector 100.

[0083] The second locking wire assembly 212 can have various structures for locking the cable end, for example, Fig. 9 and Fig.12 As shown, a wire pressing elastic member 214a is provided on the inner core body 21 (i.e., the bearing assembly 214). When the first matching portion 212b matches with the second matching portion 214e, the second wire locking assembly 212 is configured to apply pressure to the wire pressing elastic member 214a. The wire pressing elastic member 214a is used to generate elastic deformation when subjected to the pressure applied by the second wire locking assembly 212, so as to compress the conductive exposed portion 111 at the end of the cable. Specifically, the second wire locking assembly 212, for example, includes a movable body 212c, one end of which is movably connected to the inner core body 21 (i.e., the bearing assembly 214), and the other end is provided with a blocked portion 212a and a first matching portion 212b. In the case where the cable is a power cable, the blocked portion 212a is two, and is respectively provided corresponding to the screw heads 2113a of the two locking screws 2113, and the wire pressing elastic member 214a is two, which is used to compress the two conductive exposed portions 111 respectively. Optionally, the first matching portion 212b is a slot formed on the movable body 212c, and correspondingly, the second matching portion 214e is a snap-fitting member formed on the inner core body 21, such as a snap-fitting member.

[0084] Alternatively, if Fig.12As shown, a side of the movable body 212c adjacent to the line pressing elastic member 214a is also provided with a pressing protrusion 212d, and the pressing protrusion 212d is used to apply pressure to the line pressing elastic member 214a. In practical applications, the position, shape and size parameters of the above-mentioned pressing protrusion 212d can be designed to achieve the purpose of locking the cable end by the line pressing elastic member 214a when the movable body 212c moves to the position where the first matching portion 212b and the second matching portion 214e are matched. The way in which one end of the movable body 212c is movably connected to the inner core body 21 (i.e., the bearing assembly 214) is, for example, a rotating shaft 214c is rotatably provided on the inner core body 21 (i.e., the bearing assembly 214), and the movable body 212c is connected to the rotating shaft 214c and can rotate around the rotating shaft 214c.

[0085] The conductive exposed portion 111 is compressed by the elastic force applied by the wire pressing elastic member 214a, that is, the wire pressing elastic member 214a and the conductive exposed portion 111 are elastically connected, which can ensure that the conductive exposed portions 111 of cables with various wire diameters can be locked, thereby being suitable for cables with various wire diameters. The wire pressing elastic member 214a is, for example, folded from a metal sheet to form two spring sheets, which are sleeved on the first mounting axis 214f ​​on the inner core body 21, and a metal sheet close to the conductive exposed portion 111 is bent to form an approximate "S" shape, and is abutted against the second mounting axis 214g on the inner core body 21 on the side away from the conductive exposed portion 111. In this way, the first mounting axis 214f ​​and the second mounting axis 214g can play a role in limiting and fixing the wire pressing elastic member 214a. At the same time, the first mounting axis 214f ​​can also serve as the rotating axis of the wire pressing elastic member 214a. When the wire pressing elastic member 214a (that is, the other metal sheet away from the conductive exposed portion 111) is subjected to pressure applied by the second wire locking assembly 212, it can rotate around the first mounting axis 214f ​​to compress the conductive exposed portion 111 at the end of the cable.

[0086] In some embodiments, Fig.12As shown, a reset elastic member 214h is provided on the inner core body 21. When the first matching portion 212b matches with the second matching portion 214e, the second lock wire assembly 212 (for example, the above-mentioned pressing protrusion 212d) is configured to apply pressure to the reset elastic member 214h. When the first matching portion 212b and the second matching portion 214e are released from the matching, the reset elastic member 214h is used to apply elastic force to the second lock wire assembly 212 to make the first matching portion 212b away from the second matching portion 214e. In this way, when the first matching portion 212b and the second matching portion 214e are released from the matching, the second lock wire assembly 212 (for example, the movable body 212c) can be automatically opened under the elastic force of the reset elastic member 214h. In the case where the cable is a power cable, there are two reset elastic members 214h. In addition, the structure of the reset elastic member 214h is similar to that of the wire pressing elastic member 214a. For example, a metal sheet is folded to form two spring sheets, but the bending direction of the two spring sheets is different from that of the wire pressing elastic member 214a. Moreover, the two spring sheets of the reset elastic member 214h are also sleeved on the first mounting axis 214f ​​on the inner core body 21, and a metal sheet close to the conductive exposed portion 111 is bent to form an approximate "S" shape, and the second mounting axis 214g on the inner core body 21 is abutted against the second mounting axis 214g on the side away from the conductive exposed portion 111. In this way, the first mounting axis 214f ​​and the second mounting axis 214g can play a role in limiting and fixing the reset elastic member 214h.

[0087] In some embodiments, the second locking wire assembly 212 is further provided with an operating portion 212e, which is used to drive the second locking wire assembly 212 to move when subjected to a driving force. The operating portion 212e is, for example, a handle connected to the movable body 212c, and an operator can drive the second locking wire assembly 212 (i.e., the movable body 212c) to rotate through the handle.

[0088] In some embodiments, Fig. 9 and Fig.12As shown, the bearing assembly 214 includes a rotating shaft 214c, a bearing part 214b and two fixing parts 214j. The rotating shaft 214c is rotatably arranged on the bearing part 214b and the second locking wire assembly 212 (i.e., the movable body 212c) so that the movable body 212c can rotate around the rotating shaft 214c; the two fixing parts 214j are relatively arranged on the bearing part 214b and are rotatably connected to the two ends of the rotating shaft 214c respectively, so as to play the role of limiting and fixing the rotating shaft 214c. In addition, the two fixing parts 214j are also respectively limited and fixed to the two ends of the first installation shaft 214f ​​and the second installation shaft 214g. In addition, the two fixing parts 214j and the bearing part 214b together form a accommodating space 214p for accommodating the first locking wire assembly 211. In this way, the first locking wire assembly 211 (including the mounting component 211a and the locking wire component 211b) can be fixed in the above-mentioned accommodating space 214p, thereby improving the compactness of the inner core structure. Fig.10 As shown, after the two fixing members 214j are connected to the bearing member 214b, the fixing members 214j are on the opposite side of the first cavity wall 2111a of the mounting member 211a, together with the first cavity wall 2111a, the second cavity wall 2111b and the third cavity wall 2111c to form the above-mentioned accommodating cavity 2111, thereby better limiting and fixing the conductive exposed portion 111 at the end of the cable.

[0089] Specifically, Fig.13 As shown, the fixing member 214j includes a fixing wall 2141 and a supporting wall 2142, which are connected as one body and perpendicular to each other, wherein the fixing wall 2141 and the first cavity wall 2111a, the second cavity wall 2111b and the third cavity wall 2111c enclose the above-mentioned accommodating cavity 2111, and a first shaft hole 2143 and two second shaft holes 2144 are formed on the surface of the fixing wall 2141 facing the bearing member 214b, wherein the first shaft hole 2143 is rotatably connected to one end of the rotating shaft 214c, that is, one end of the rotating shaft 214c is inserted into the first shaft hole 2143, and is used to play a role of limiting and fixing the rotating shaft 214c together with another fixing member 214j. The two second shaft holes 2144 are respectively connected to one end of the first installation shaft 214f ​​and the second installation shaft 214g, that is, one end of the first installation shaft 214f ​​and the second installation shaft 214g is respectively inserted into the two second shaft holes 2144.

[0090] In some embodiments, Figure 6 and Figure 7 As shown, one end of the inner core shell 213 ( Figure 7The inner core further comprises a shielding member 215 and a clamping member 216. The shielding member 215 comprises an annular portion 215a and an extending portion 215b. The annular portion 215a is disposed around the outer periphery of the inner core outer shell 213 and is located at one end of the inner core outer shell 213 away from the insertion port ( Figure 7 one end of the extension portion 215b is connected to the annular portion 215a, and the other end extends to the side where the insertion port of the inner core housing 213 is located, that is, Figure 7 The right side of the inner core shell 213 passes through the clamping assembly 216 and the protective cover of the cable, and is in electrical contact with the shielding layer covering the core wire. Specifically, the conductor of the core wire is covered with an insulating layer on the outside, the insulating layer is covered with a conductive shielding layer on the outside, and the shielding layer is covered with an insulating protective cover on the outside. The extension 215b passes through the protective cover and is in electrical contact with the shielding layer. The clamping assembly 216 is connected to the extension 215b, and the cable 1 is clamped and fixed. Specifically, two connecting columns 215c are provided at one end of the extension 215b close to the insertion port, and the connecting columns 215c are used to pass through the clamping assembly 216 and the protective cover of the cable core wire, and are in electrical contact with the shielding layer of the core wire. The above-mentioned shielding member 215 is used to be electrically connected with another shielding member (not shown in the figure) in the adapter 3, and the other shielding member in the adapter 3 is grounded through a grounding member (not shown in the figure), so as to achieve a shielding effect against lightning strikes. On this basis, by connecting the connecting column 215c and the shielding layer of the core wire in electrical contact, the cable can also be shielded against lightning strikes, and the cable 1 can be clamped and fixed by the clamping assembly 216, which can further improve the stability and reliability of the locked cable. Optionally, in the case where the cable is a power cable, the clamping assembly 216 is used to clamp the unbranched part of the power cable.

[0091] In some embodiments, Figure 7As shown, the bearing assembly 214 also includes a supporting member 214q, which is connected to the bearing member 214b and is located outside the inner core shell 213 and adjacent to the insertion port. The supporting member 214q has a receiving slot for allowing the cable to pass through and support the cable. Taking the cable as a power cable as an example, the receiving slot is used to support the positive branch 11 and the negative branch 12, and an isolation protrusion 2147 is provided at one end of the receiving slot close to the bearing member 214b to separate the positive branch 11 from the negative branch 12. A hollow portion 2146 is provided at the bottom of the receiving slot and at one end away from the bearing member 214b. The other end of the extension portion 215b extends to the position of the hollow portion 2146. The clamping assembly 216 is provided in the receiving slot and connected to the extension portion 215b through the hollow portion 2146. By supporting the cable with the accommodating groove of the above-mentioned supporting component 214q, the stability and reliability of locking the cable can be further improved. On this basis, by arranging the clamping component 216 in the hollow portion 2146 in the accommodating groove, the compactness of the inner core structure can be further improved.

[0092] In some embodiments, the inner core body 21 is further provided with a plurality of windows, each of which corresponds to the position of the ends of the cables locked by the plurality of locking wire assemblies. Specifically, for example, the plurality of locking wire assemblies include a first locking wire assembly and a second locking wire assembly. Figure 7 As shown, there are two viewing windows, namely, the first viewing window and the second viewing window, wherein the first viewing window includes a first sub-window 213b provided on the inner core outer shell 213 and a second sub-window 2148 provided on the bearing component 214b corresponding to the first sub-window 213b, and the first viewing window corresponds to the position where the first locking wire assembly 211 locks the end of the cable, that is, the area where the locking screw 2113 is located. The second viewing window includes a third sub-window 213c provided on the inner core outer shell 213 and a fourth sub-window 2145 provided on the fixing member 214j corresponding to the third sub-window 213c, and the second viewing window corresponds to the position where the second locking wire assembly 212 locks the end of the cable, that is, the area where the pressing wire elastic member 214a is located. With the help of the first viewing window and the second viewing window, after the first locking wire assembly 211 and the second locking wire assembly 212 have completed the locking wire respectively, the internal locking wire situation can be visually observed through the first viewing window and the second viewing window to determine whether the cable is crimped normally, thereby improving the usability of the project.

[0093] As another technical solution, an embodiment of the present disclosure further provides a power supply device, including a power supply and a cable connector, wherein the cable of the power supply is electrically connected to a circuit board of a device to be powered via the cable connector, and the cable connector adopts the above-mentioned cable connector 100 provided in an embodiment of the present disclosure.

[0094] The power supply device provided by the embodiment of the present disclosure can realize multiple locking of the cable 1 by adopting the above-mentioned cable connector 100 provided by the embodiment of the present disclosure, thereby ensuring that the locking effect is reliable for a long time. On this basis, by making a part of the multiple locking wire components block at least one locking wire component in another part when not locked in place, so that at least one locking wire component in another part cannot lock the end of the cable 1, it can be ensured that the locking operation of at least one locking component in another part can be performed only after a part of the locking components is locked in place, that is, the installation sequence of the connector is restricted, and the effect of fool-proof and error-proof operation is achieved, and the engineering fault tolerance of the cable connector 100 is improved. At the same time, because the probability of operation error is reduced, the problem of poor assembly of the cable connector 100 can be reduced or even avoided. In the case where the cable connector 100 is applied to the power connector, the risk of severe heating caused by excessively high contact resistance inside the connector can be reduced, thereby ensuring the performance and life of the power connector and avoiding serious accidents such as circuit failure or equipment burning.
