[0056] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] It should also be understood that the terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0058] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0059] like Figures 1-10 As shown, the present application provides an insulating base 10 , which can be specifically applied to a cable connector 20 .

[0060] like Figure 1As shown, the insulating base 10 includes a first base portion 110 and a plurality of first extension portions 120, wherein the first extension portions 120 are circumferentially arranged around the first base portion 110, that is, the first base portion 110 is radially arranged, and the plurality of first extension portions 120 are spaced apart from each other, so that a receiving groove 130 is formed between two adjacent first extension portions 120 and the first base portion 110.

[0061] Optionally, at least a portion of the first base portion 110 constitutes a bottom wall of the accommodating groove 130 , and at least a portion of the two adjacent first extension portions 120 constitutes two side walls of the accommodating groove 130 .

[0062] In an optional embodiment, the number of the first extension portions 120 may be greater than or equal to 4, and may specifically be 4 or 5, which is not limited here.

[0063] In an alternative embodiment, the first extension portions 120 are evenly distributed along the circumference of the first base portion 110 .

[0064] like Figure 1 and Figure 5 As shown, the insulating base 10 includes a first base subunit 200 and a second base subunit 300 , wherein the first base subunit 200 and the second base subunit 300 are separable from each other, that is, they are two independent parts.

[0065] The first base subunit 200 and the second base subunit 300 can be detachably connected in the axial direction to form the insulating base 10 .

[0066] It should be noted that the detachable connection between the first base sub-unit 200 and the second base sub-unit 300 mentioned in this application means that the first base sub-unit 200 and the second base sub-unit 300 can be disassembled. Regardless of whether they are connected together by bonding, threaded fixation or snap fastening, the first base sub-unit 200 and the second base sub-unit 300 can be separated by corresponding methods.

[0067] In the above embodiment, by setting the first base sub-unit 200 and the second base sub-unit 300 as two independent parts separated from each other, and then connecting them together axially and detachably to form a complete insulating base 10, the axial length of a single base sub-unit (the first base sub-unit 200 or the second base sub-unit 300) can be effectively reduced, thereby reducing the processing difficulty and process requirements.

[0068] like Figure 3 and Figure 4As shown, the first base subunit 200 includes a second base portion 210 and a plurality of second extensions 220 circumferentially disposed around the second base portion 210 . The second base subunit 300 includes a third base portion 310 and a plurality of third extensions 320 circumferentially disposed around the third base portion 310 .

[0069] Optionally, the number of the first extension portions 120 , the number of the second extension portions 220 and the number of the third extension portions 320 are the same.

[0070] Optionally, when the first base sub-unit 200 and the second base sub-unit 300 are connected, the second base portion 210 and the third base portion 310 thereof form the first base portion 110, and each of the plurality of second extension portions 220 and a corresponding third extension portion 330 of the plurality of third extension portions 320 form the first extension portion 120. That is, when the first base sub-unit 200 and the second base sub-unit 300 are connected, for each of the plurality of second extension portions 220, there is a corresponding third extension portion 320 on the second base sub-unit 300, and together they form the first extension portion 120.

[0071] Optionally, a first receiving groove 260 is formed between adjacent second extension portions 220 and the second base portion 210 .

[0072] When the first base sub-unit 200 and the second base sub-unit 300 are connected, at least a portion of the first receiving groove 260 forms at least a portion of the receiving groove 130 .

[0073] In an alternative embodiment, the receiving groove 130 may include all or part of the first receiving groove 260 .

[0074] In an optional embodiment, a second accommodating groove 360 is formed between the adjacent third extending portion 320 and the second base portion 310 , and the first accommodating groove 260 and the second accommodating groove 360 form the accommodating groove 130 .

[0075] In an optional embodiment, the accommodating groove 130 is formed by only a portion of the first accommodating groove 260 , which is not limited here.

[0076] like Figure 3 and Figure 4 As shown, the second base portion 210 is provided with a fixing hole 211, and the third base portion 310 is provided with a matching hole 311. The insulating base 10 also includes a fixing member (not shown in the figure), which can pass through the matching hole 311 and be fixedly matched with the fixing hole 211, thereby connecting the first base sub-unit 200 and the second base sub-unit 300.

[0077] In an optional embodiment, the fixing hole 211 can be a threaded hole, and its matching hole 311 can also be a threaded hole or a sliding hole, and its fixing piece (not shown) can be a threaded piece. By passing through the matching hole 311 and matching with the fixing hole 211, the second base part 210 and the third base part 310 can be fixed together, thereby connecting the first base sub-unit 200 and the second base sub-unit 300.

[0078] In an optional embodiment, the fixing hole 211 may be disposed along the axial direction of the second base portion 210 , and the matching hole 311 thereof may also be disposed along the axial direction of the third base portion 310 .

[0079] In other embodiments, the fixing hole 211 can be arranged along the radial direction of the second base portion 210, and the matching hole 311 can also be arranged along the radial direction of the third base portion 310. Specifically, the second base portion 210 and the third base portion 310 can be nested axially and then fixed using radial fixing members (not shown).

[0080] It should be noted that the fixing member (not shown) may also be located in the matching hole 311 and fixed together with the second base sub-unit 300 , thereby achieving matching between the fixing member (not shown) and the fixing hole 211 .

[0081] In an optional embodiment, the fixing member (not shown) may also be other types such as expansion screws, and the fixing hole 211 and the matching hole 311 may also be compatible structures.

[0082] In an optional embodiment, the first base subunit 200 is provided with a first fastener (not shown), and the second base subunit 300 is provided with a second fastener (not shown), and the first base subunit 200 and the second base subunit 300 are connected by the first fastener and the second fastener.

[0083] In an optional embodiment, the first fastener may be disposed on the second base portion 210 or the second extending portion 220 , and the second fastener may be correspondingly disposed on the third base portion 310 or the third extending portion 320 .

[0084] Optionally, the first fastener and the second fastener may be common fastener structures, which are not limited here.

[0085] In an optional embodiment, the first base subunit 200 is provided with a first bonding surface (not shown in the figure), and the second base subunit 300 is provided with a second bonding surface (not shown in the figure), and the first base subunit 200 and the second base subunit 300 are connected by the bonding cooperation of the first bonding surface and the second bonding surface.

[0086] In an optional implementation, the first bonding surface (not shown) and the second bonding surface (not shown) can be fixed together by glue.

[0087] like Figure 3 and Figure 4 as well as Figure 5 As shown, the first base subunit 200 is provided with a first docking member 230 , and the second base subunit 300 is provided with a second docking member 330 .

[0088] Optionally, the first docking member 230 and the second docking member 330 can be docked and matched, so that the first base subunit 200 and the second base subunit 300 can be nested and matched with each other, which facilitates better docking and fixation of the first base subunit 200 and the second base subunit 300.

[0089] As an option, the first docking member 230 and the second docking member 330 may be docked and matched first, and then the first base sub-unit 200 and the second base sub-unit 300 may be fixed by screwing or snapping.

[0090] In an optional embodiment, the first docking member 230 and the second docking member 300 may be docked and mated to limit the circumferential movement of the first base subunit 230 relative to the second base subunit 300. That is, the first docking member 230 and the second docking member 300 serve as circumferential limiters to limit the relative circumferential movement of the first base subunit 230 and the second base subunit 300.

[0091] In an optional embodiment, the first docking member 230 includes one of a non-circular groove and a non-circular protrusion provided on the second base portion 210 , and the second docking member 330 includes the other of the non-circular groove and the non-circular protrusion provided on the third base portion 310 .

[0092] Specifically, the first docking member 230 may be a pentagonal groove, and the second docking member 330 may be a corresponding pentagonal protrusion, which can achieve not only docking but also circumferential limitation through nesting.

[0093] In other embodiments, the first docking member 230 is a circular groove provided on the second base portion 210 , and the second docking member 330 is a circular protrusion provided on the third base portion 310 , thereby facilitating better docking.

[0094] In an optional embodiment, at least a portion of the fixing hole 211 is disposed on the first docking member 230 , and at least a portion of the matching hole 311 is disposed on the second docking member 330 , thereby effectively saving the volume of the entire insulating base 10 .

[0095] In an optional embodiment, the axes of the fixing hole 211 and the matching hole 311 coincide with the axis of the first base portion 110 , which makes the fixation more stable.

[0096] In an optional embodiment, the first docking member 230 includes one of a docking groove and a docking protrusion provided on the second extension portion 220 , and the second docking member 330 includes the other of the docking groove and the docking protrusion provided on the third extension portion 320 .

[0097] As an option, the first docking member 230 includes a docking groove arranged on the second extension portion 220, and the second docking member 330 includes a docking protrusion arranged on the third extension portion 320. Through the cooperation of the docking grooves and the docking protrusions of the second extension portion 220 and the third extension portion 320, not only docking cooperation can be achieved, but also circumferential limitation can be achieved.

[0098] In an alternative embodiment, the first base subunit 200 and the second base subunit 300 may be identical subunits. That is, the first base subunit 200 and the second base subunit 300 may have the same size and shape to complete the same structure, and different lengths of the insulating base 10 can be formed by assembling different numbers of first base subunits 200 (second base subunits 300).

[0099] In an optional embodiment, the second base portion 210 is provided with a first docking member 230 and a second docking member 330 at both ends along the axial direction. In other words, the second base portion 210 of the first base subunit 200 is provided with the first docking member 230 and the second docking member 330, so that it can dock with another first base subunit 200, which can better adapt to the connection of two or more first base subunits 200.

[0100] In an optional embodiment, the number of the plurality of second extensions 220 is five, and the plurality of second extensions 220 are evenly distributed around the second base portion 210. At least one of the five second extensions 220 is provided with a groove, and at least one of the plurality of second extensions 220 is provided with a protrusion that fits the groove. Furthermore, the number of second extensions 220 provided with grooves is greater than or equal to the number of second extensions 220 provided with protrusions.

[0101] Optionally, three of the five second extension portions 220 are provided with grooves, and two of the second extension portions 220 are provided with protrusions, so that when two first base sub-units 200 are docked, the two protrusions of one first base sub-unit 200 cooperate with the two grooves of the other first base sub-unit 200, the two grooves cooperate with the two protrusions of the other first base sub-unit 200, and one groove is empty with one groove of the other first base sub-unit 200.

[0102] Optionally, one of the five second extension portions 220 is provided with a groove, and one second extension portion 220 is provided with a protrusion, then one protrusion of one first base sub-unit 200 cooperates with one groove of another first base sub-unit 200, and one groove cooperates with one protrusion of another first base sub-unit 200.

[0103] In this way, the circumferential limitation of the two first base sub-units 200 can be achieved.

[0104] In an optional embodiment, the axial length ratio of the first base subunit 200 and the second base subunit 300 is greater than 0.7 and less than or equal to 1.4. This ensures that the axial length difference between the first base subunit 200 and the second base subunit 300 is within a certain range, which is beneficial to improving the stability of the entire first base subunit 200 and the second base subunit 300.

[0105] like Figure 6 As shown, the present application further provides a cable connector 20 , which includes the insulating base 10 of any of the above embodiments.

[0106] In an optional embodiment, the cable connector 20 further includes a cable assembly 400 and a fixing member 500 detachably connected to the cable assembly 400 .

[0107] Optionally, the cable assembly 400 can be accommodated in the receiving groove 130 of the insulating base 10 .

[0108] Optionally, the first extension portion 110 abuts against at least a portion of both sides of the cable assembly 400 , thereby limiting the circumferential position of the cable assembly 400 relative to the first base portion 110 .

[0109] The fixing member 500 can be detachably matched with the cable assembly member 400 to electrically connect the main cable and the branch cable, thereby transmitting power from the main cable to the branch cable.

[0110] In an optional implementation, each accommodating groove 130 can correspond to a cable assembly 400. A cable assembly 400 and a fixing part 500 can electrically connect one core of the main cable and one core of the branch cable together. Through multiple cable assemblies 400 and fixing parts 500, the electrical connection of multi-core main cables and branch cables can be achieved.

[0111] In an optional embodiment, a first limit plate 250 is provided on the first base subunit 200, and a second limit plate 350 is provided on the second base subunit 300. When the first base subunit 200 and the second base subunit 300 are connected, the first limit plate 250 and the second limit plate 350 are used to limit the axial movement of the cable assembly 400 of the accommodating groove 130.

[0112] In an optional embodiment, the first limiting plate 250 and the second limiting plate 350 are both perpendicular to the axial direction of the first base portion 110 .

[0113] Specifically, the first limiting plate 250 is perpendicular to the axial direction of the second base portion 210 , and the second limiting plate 350 is perpendicular to the axial direction of the third base portion 310 .

[0114] Optionally, by setting the first limiting plate 250 on the first base sub-unit 200 and setting the second limiting plate 350 on the second base sub-unit 200, it is convenient to first assemble one end of the cable assembly 400 in the first accommodating groove 260 of the first base sub-unit 200 and abut against the first limiting plate 250 during assembly, and then dock the second base sub-unit 300 with the other end of the cable assembly 400, and make the second limiting plate 350 abut against the other end of the cable assembly 400, and then connect the second base sub-unit 300 with the first base sub-unit 200, so that the cable assembly 400 is well restricted in the accommodating groove 130 from both ends, which greatly saves assembly efficiency.

[0115] In an optional embodiment, the first limiting plate 250 includes a first sub-limiting plate 251 arranged on the second base portion 210 and / or a second sub-limiting plate 252 arranged on the second extension portion 220, and the second limiting plate 252 includes a third sub-limiting plate 351 arranged on the third base portion 310 and / or a fourth sub-limiting plate 352 arranged on the third extension portion 320, which can achieve better limiting of the cable assembly 400.

[0116] In an optional embodiment, the first extending portion 120 is provided with a first radial limiting member 121 along the axial direction; and the cable assembly 400 includes a second radial limiting member 410 .

[0117] Among them, the second radial limiter 410 cooperates with the first radial limiter 121 so that the cable assembly 400 can be assembled in the accommodating groove 130, and the second radial limiter 410 and the first radial limiter 121 are further used to radially limit the cable assembly 400 relative to the first base part 110.

[0118] like Figure 10 As shown, when the cable assembly 400 is assembled in the accommodating groove 130, the bottom of the cable assembly 400 contacts the first base portion 110, and the second radial limiting member 410 and the first radial limiting member 121 can limit the cable assembly 400 from moving in a direction away from the first base portion 110.

[0119] Optionally, one of the first radial limiting member 121 and the second radial limiting member 410 is a sliding groove, and the other is a sliding rib.

[0120] In an optional embodiment, the two first extension portions 120 corresponding to each accommodating groove 130 are both provided with a first radial limiting member 121 facing the accommodating groove 130 .

[0121] Optionally, the axial displacement of the cable assembly 400 is limited by the first limiting plate 250 and the second limiting plate 350, the radial displacement of the cable assembly 400 is limited by the second radial limiting member 410 and the first radial limiting member 121, and the circumferential displacement of the cable assembly 400 is limited by the first extension portion 110. By doing so, the cable assembly 400 can be well clamped in the accommodating groove 130, thereby greatly improving its stability.

[0122] In an optional embodiment, the first radial limiting member 121 includes a third radial limiting member 212 disposed on the second extending portion 210 .

[0123] In other embodiments, the first radial limiting member 121 may further include a fourth radial limiting member 312 disposed on the third extending portion 310 .

[0124] like Figure 7-Figure 9As shown, in order to ensure the stability of the cable assembly 400 in the accommodating groove 130, the cable assembly 400 has three-directional limitations (radial, axial and circumferential) in the accommodating groove 130, which will also affect the assembly of the cable assembly 400 in the accommodating groove 130. In this application, the first base sub-unit 200 and the second base sub-unit 300 are separated. During the assembly process, one end of the cable assembly 400 can be first assembled in the first accommodating groove 260 of the first base sub-unit 200, and the second radial limiting member 410 is aligned with the third radial limiting member 212 so as to slide into the first accommodating groove 260 and push to the bottom so as to abut against the first limiting plate 250. , then dock the second base subunit 300 with the other end of the cable assembly 400, align the fourth radial limit member 312 (if any) with the second radial limit member 410 so that the cable assembly 400 slides into the third accommodating groove 360 (if any), and make the second limit plate 350 abut against the other end of the cable assembly 400, and then connect the second base subunit 300 with the first base subunit 200, so that the cable assembly 400 is well restricted in the accommodating groove 130 from both ends, which greatly saves assembly efficiency. In this way, there is no need to independently disassemble and assemble each limit member, which greatly improves the stability of the limit member itself and also improves the stability of its limit.

[0125] Similarly, due to the presence of multiple limiting parts, by splitting it into the first base sub-unit 200 and the second base sub-unit 300, it is also beneficial to the development and use of the mold and reduces its process difficulty.

[0126] like Figure 3 As shown, the first limiting plate 250 can also extend toward the first radial limiting member 121 to form a blocking member of the first radial limiting member 121 to block the second radial limiting member 410, that is, to form a blocking member that blocks one end of the second radial limiting member 410 from further moving axially.
