[0031] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "a plurality" appears, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for the purpose of illustration and do not represent the only implementation manner.

[0035] Referring to Figures 1 to 3 , Figure 1 shows an axonometric schematic diagram of the mixed plug-in core component provided by an embodiment of the present application, Figure 2 is Figure 1 the top view of the mixed plug-in core component after hiding the housing shown, Figure 3 is Figure 2Explosion schematic diagram of the mixed plug-in core assembly shown. An embodiment of the present application provides a mixed plug-in core assembly 10, and the mixed plug-in core assembly 10 can be used as a conduction part of a connector for transmitting electric energy, electrical signals, optical signals, etc. The mixed plug-in core assembly 10 includes a first ring frame 100, a support structure 200, and terminals 300. The support structure 200 and the terminals 300 are both arranged on the first ring frame 100. The first ring frame 100 is provided with a first installation groove 110, and a plurality of first installation grooves 110 are arranged around the circumferential direction of the first ring frame 100. The area of the plurality of first installation grooves 110 close to the circumferential outer side of the first ring frame 100 has a first opening 111. The support structure 200 includes a second ring frame 210, and the second ring frame 210 is provided with a plurality of second installation grooves 210a. The support structure 200 is installed in the first installation groove 110 through the first opening 111. Some of the terminals 300 are correspondingly installed in the plurality of first installation grooves 110 through the first opening 111, and some of the terminals 300 are installed in the second installation grooves 210a.

[0036] In the above-mentioned mixed plug-in core assembly 10, a plurality of first installation grooves 110 are arranged around the circumferential direction of the first ring frame 100, and the area of the plurality of first installation grooves 110 close to the circumferential outer side of the first ring frame 100 has a first opening 111. Thus, a plurality of terminals 300 can be correspondingly installed in the plurality of first installation grooves 110 through the first opening 111 to complete the assembly, and the assembly is simple and easy to achieve. Further, some of the terminals 300 can also be installed in the second installation grooves 210a of the second ring frame 210 to form an assembly module with the support structure 200. Moreover, the support structure 200 loaded with the terminals 300 (i.e., the above-mentioned assembly module) can also be installed in the first installation groove 110 through the first opening 111, taking into account the space utilization rate of the first ring frame 100 while facilitating the assembly.

[0037] It can be understood that the first installation groove 110 needs to communicate with the outside through the first opening 111 located on the circumferential outer side for the terminal 300 to be inserted. The shape and size of the first installation groove 110 are generally adapted to the terminal 300 to be inserted, so as to position the terminal 300. Therefore, when configuring the first installation groove 110 to communicate with the outside through the first opening 111, it is often necessary to arrange the first installation groove 110 in the relatively outer peripheral area of the first ring frame 100. When the terminal 300 has a relatively large size, the space on the first ring frame 100 can be fully utilized after the terminal 300 is inserted into the first installation groove 110; when the size of the terminal 300 is small, only a partial area of the relatively outer periphery of the first ring frame 100 is utilized after the terminal 300 is inserted into the first installation groove 110. Considering the above problem of space utilization, the present application further provides a bracket structure 200. By using the bracket structure 200, multiple terminals 300 can be carried and inserted into the first installation groove 110 at the same time. The terminals 300 provided on the bracket structure 200 can be fixed relative to the first ring frame 100 through the bracket structure 200. Therefore, the influence of the position of the first installation groove 110 and its first opening 111 on the arrangement position of the terminal 300 is reduced, and the space utilization rate of the first ring frame 100 can be fully improved. In short, such a setting takes into account the space utilization rate of the first ring frame 100 while facilitating assembly.

[0038] Please refer to Figure 4 , in one embodiment, a plurality of second installation grooves 210a are arranged around the circumferential direction of the second ring frame 210. The area of the plurality of second installation grooves 210a close to the circumferential outer side of the second ring frame 210 has a second opening 210b, and the second opening 210b is used for communicating with the outside, so that some terminals 300 can be correspondingly clamped in the plurality of second installation grooves 210a through the second opening 210b. Thus, similar to the first ring frame 100, the terminal 300 can also be conveniently inserted into the second installation groove 210a, and then the whole is inserted into the first installation groove 110 along with the bracket structure 200 and fixed to the first ring frame 100.

[0039] Please refer to Figure 3 and Figure 4 , in one embodiment, a plurality of first installation grooves 110 are arranged at intervals around the circumferential direction of the first ring frame 100. A plurality of second installation grooves 210a are arranged at intervals around the circumferential direction of the second ring frame 210.

[0040] Please refer to Figure 3 and Figure 4, in one embodiment, the terminal 300 can be divided into a first terminal and a second terminal. The first terminal is directly installed in the first installation groove 110; after the second terminal is installed in the second installation groove 210a, it is then installed in the first installation groove 110 together with the bracket structure 200. At this time, the second terminal is integrally arranged on the bracket structure 200 and is spaced from the first terminal. That is to say, the hybrid ferrule assembly 10 provided in this application can also achieve the zonal arrangement of the terminals 300. As an example, the first terminal and the second terminal can be terminals 300 with different transmission media. The first terminal can be used to transmit electrical energy or electrical signals, and the second terminal is used to transmit optical signals. Configuring the second terminal to be integrally arranged relative to the first terminal can reduce the risk that the static electricity and leakage that may occur in each first terminal affect the transmission stability of the second terminal. For another example, the first terminal and the second terminal can be terminals 300 with different electrical characteristics. The first terminal can be used to transmit electrical energy (strong electricity), and the second terminal can be used to transmit electrical signals (weak electricity). Therefore, configuring the second terminal to be integrally arranged relative to the first terminal can separate the strong electricity from the weak electricity and improve the transmission stability.

[0041] Please refer to Figure 6 , in conjunction with Figure 4 and Figure 5 , in one embodiment, the bracket structure 200 further includes a shielding sleeve 220 and an insulating sleeve 230. The shielding sleeve 220 is sleeved outside the second ring bracket 210, and the insulating sleeve 230 is sleeved outside the second ring bracket 210 and is located inside the shielding sleeve 220.

[0042] The shielding sleeve 220 has conductivity, that is, the shielding sleeve 220 can conduct electricity. The shielding sleeve 220 is sleeved outside the second ring bracket 210 to form electromagnetic interference protection for the terminals 300 installed on the second ring bracket 210, reduce the influence of static electricity that may be generated externally on the terminals 300 inside, and at the same time, the shielding sleeve 220 can also reduce signal radiation and play the role of preventing internal interference from leaking out.

[0043] Furthermore, the shielding sleeve 220 is used to be inserted into the shielding sleeve 220 of another terminal structure (which can also be configured as the hybrid ferrule assembly 10) to enclose the second ring bracket 210. That is to say, the shielding sleeves 220 of the two mating hybrid ferrule assemblies 10 can also be inserted into each other to wrap outside the terminals 300 to form a Faraday cage effect and block the interference of external electromagnetic fields (such as radio waves and power supply noise) on internal signals.

[0044] Please refer to Figure 5 , in conjunction with Figure 1 and Figure 2, in one embodiment, the hybrid ferrule assembly 10 further includes a housing 400 sleeved outside the first ring frame 100. The housing 400 is provided with a communication hole 411 for the bracket structure 200 to be exposed to the outside. That is, when the hybrid ferrule assembly 10 is plugged into another terminal structure, the terminal 300 carried by the bracket structure 200 is connected to the terminal 300 of the other terminal structure through the communication hole 411.

[0045] The shielding sleeve 220 includes a connecting tongue 221, a sleeve body 222 and a sliding tongue 223. The sleeve body 222 is sleeved outside the insulating sleeve 230. The connecting tongue 221 is connected to the end of the sleeve body 222, and the connecting tongue 221 penetrates through the communication hole 411. The connecting tongue 221 is spaced from the hole wall of the communication hole 411 on its outer side, and / or the connecting tongue 221 is spaced from the insulating sleeve 230 on its inner side to form a slot 224. The slot 224 is used for plugging and electrically conducting with the connecting tongue 221 of the other terminal structure. Thus, the shielding sleeves 220 of the hybrid ferrule assembly 10 with two pairs of plugs can be stably plugged together to wrap around the terminal 300 and reduce the interference received by the terminal 300.

[0046] Please refer to Figure 6 , in combination with Figure 1 and Figure 2 , in one embodiment, the number of the connecting tongues 221 is multiple. The multiple connecting tongues 221 are divided into a first connecting tongue 221a and a second connecting tongue 221b. In the radial direction of the shielding ring, the second connecting tongue 221b is located in the inner circle relative to the first connecting tongue 221a to fit and support the insulating sleeve 230. The first connecting tongue 221a is spaced from the insulating sleeve 230 to form a first slot 224a, and the second connecting tongue 221b is spaced from the hole wall of the communication hole 411 to form a second slot 224b. When the two hybrid ferrule assemblies 10 are plugged together, the first connecting tongue 221a is plugged into the second slot 224b of the other hybrid ferrule assembly 10, and the second connecting tongue 221b is plugged into the first slot 224a of the other hybrid ferrule assembly 10 to form a stable plug and wrap the terminals 300 carried by the second ring frames 210 of the two hybrid ferrule assemblies 10 inside.

[0047] Please refer to Figure 7 and Figure 8 , in one embodiment, the insulating sleeve 230 includes a first clamping portion 231, and the second ring frame 210 includes a second clamping portion 213. The first clamping portion 231 and the second clamping portion 213 are clamped and limited to fix the second ring frame 210 relative to the insulating sleeve 230.

[0048] Further, the first clamping portion 231 is configured as a clamping groove, and the second clamping portion 213 is configured as a clamping block.

[0049] Please refer to Figure 9 , in combination with Figure 7 and Figure 8, in one embodiment, the second ring frame 210 includes a frame body 211 and guiding fins 212, and the guiding fins 212 are arranged on the frame body 211. The frame body 211 has a first side 211a, a second side 211b, a third side 211c, and a fourth side 211d. In the circumferential direction of the frame body 211, the first side 211a, the second side 211b, the third side 211c, and the fourth side 211d are sequentially distributed, and the third side 211c is disposed opposite to the first side 211a, and the fourth side 211d is disposed opposite to the second side 211b. The guiding fins 212 protrude from the first side 211a, and two second mounting grooves 210a are located on opposite sides of the guiding fins 212, and the second openings 210b of the two second mounting grooves 210a communicate with the outside on the first side 211a. Thus, the two terminals 300 can be loaded into the second mounting grooves 210a together along the guiding fins 212 from the first side 211a, which is convenient for automatic assembly using automated equipment.

[0050] The second engaging portion 213 is disposed on the second side 211b and / or the fourth side 211d. Since the second opening 210b communicates with the outside on the first side 211a, the second engaging portion 213 is disposed on the second side 211b and / or the fourth side 211d, which neither interferes with the assembly of the terminal 300 nor requires sufficient space for arrangement.

[0051] Further, the guiding fins 212 can also protrude from the third side 211c. Another two second mounting grooves 210a are located on opposite sides of the guiding fins 212, and the second openings 210b of the another two second mounting grooves 210a communicate with the outside on the third side 211c. Thus, another two terminals 300 can be loaded into the second mounting grooves 210a together along the guiding fins 212 from the third side 211c, which is convenient for automatic assembly using automated equipment.

[0052] Of course, the above is only an example to illustrate the distribution of the second mounting grooves 210a on the second ring frame 210, and the second mounting grooves 210a can also be set to have other numbers and distributions according to requirements.

[0053] In this embodiment, the guiding fins 212 and the second openings 210b are arranged on the first side 211a and the third side 211c, and the second engaging portion 213 is arranged on the second side 211b and / or the fourth side 211d, which can make full use of the mounting space on the frame body 211, and enable the second ring frame 210 to carry the terminals 300 and be fixedly connected to the insulating sleeve 230 within a limited space.

[0054] Please continue to refer to Figure 9, in one embodiment, the second installation groove 210a includes a first limiting portion 210c, and the first limiting portion 210c is provided on the groove wall of the second installation groove 210a. Some terminals 300 are provided with a second limiting portion 310, and the first limiting portion 210c is in limiting cooperation with the second limiting portion 310, so that the terminal 300 can be stably installed in the second installation groove 210a.

[0055] Please refer to Figure 9 , and in combination with Figure 6 , in one embodiment, the second installation groove 210a includes a snap ring, that is, the first limiting portion 210c can be configured as a snap ring, and the snap ring protrudes from the groove wall of the second installation groove 210a. A ring groove is formed on the outer periphery of some terminals 300, that is, the second limiting portion 310 is configured as a ring groove. The snap ring is in snap-fit with the ring groove and abuts against the groove wall of the ring groove along the axial direction of the terminal 300. Thus, the terminal 300 can be limited by the snap ring, so that the terminal 300 is stably located in the second installation groove 210a.

[0056] Further, the snap ring can be configured such that the central angle α is greater than 180° to stably snap-fit the terminal 300. The snap ring includes an inlet 210d corresponding to the second opening 210b. In the direction from the outside of the second installation groove 210a to the inside of the second installation groove 210a, the size of the inlet 210d gradually decreases, so as to facilitate guiding the terminal 300 into the second installation groove 210a and restricting the terminal 300 from accidentally coming out of the second installation groove 210a.

[0057] In another embodiment, the first limiting portion 210c and the second limiting portion 310 can also be configured in other limiting ways. For example, one of the first limiting portion 210c and the second limiting portion 310 is configured as a convex portion, and the other is configured as a groove corresponding to the convex portion. The terminal 300 can be stably installed in the second ring frame 210 through the cooperation of the convex portion and the groove.

[0058] Please refer to again Figure 7 and Figure 8 , in one embodiment, a first guide groove 232 and a limiting groove 233 are recessed on the inner wall of the insulating sleeve 230, and the inner wall where the first guide groove 232 is located and the inner wall where the limiting groove 233 is located face each other. A part of the guiding fin 212 further protrudes away from the frame body 211 to form a plate body 212a. Among the plate bodies 212a of the guiding fins 212 on the first side 211a and the plate bodies 212a of the guiding fins 212 on the third side 211c, one extends along the axial direction of the second ring frame 210 and is used for guiding cooperation with the first guide groove 232 to play a guiding role when the second ring frame 210 and the insulating sleeve 230 are axially sleeved; the other is in limiting cooperation with the limiting groove 233, and the plate bodies 212a of the two guiding fins 212 cooperate with each other to limit the circumferential rotation of the second ring frame 210 relative to the insulating sleeve 230.

[0059] Please refer to Figure 6 , in one embodiment, the sliding tongue 223 of the shielding sleeve 220 is provided on the inner wall of the sleeve body 222, and a second guide groove 234 is formed on the outer periphery of the insulating sleeve 230. The sliding tongue 223 is slidably engaged with the second guide groove 234 to play a guiding role when the insulating sleeve 230 and the shielding sleeve 220 are axially sleeved together.

[0060] Please refer to Figure 3 、 Figure 5 and Figure 6 , and in combination with Figure 3 , in one embodiment, a strip groove 222a is formed on the outer periphery of the shielding sleeve 220, and the strip groove 222a extends along the circumferential direction of the shielding sleeve 220. A limiting hook 112 is provided on the groove wall of the first installation groove 110 for installing the bracket structure 200. The limiting hook 112 includes a hook rod 112a and a hook portion 112b. The hook portion 112b is connected to one end of the hook rod 112a close to the first opening 111. The hook rod 112a is in guiding cooperation with the strip groove 222a, and the hook portion 112b is clamped with the shielding sleeve 220 and / or the insulating sleeve 230. Thus, after the bracket structure 200 is inserted into the first installation groove 110, under the clamping action of the hook portion 112b with the shielding sleeve 220 and / or the insulating sleeve 230, it can be stably arranged on the first ring bracket 100.

[0061] Further, the hook portion 112b can be hooked into the second guide groove 234 and clamped with the groove wall of the second guide groove 234, so that the second guide groove 234 is not only used to guide the axial sleeving of the insulating sleeve 230 and the shielding sleeve 220, but also used to cooperate with the hook portion 112b for clamping and limiting. Thus, the structure of the shielding sleeve 220 can be relatively simplified.

[0062] Please refer to Figure 3 and Figure 6 , in one embodiment, the shielding sleeve 220 includes a head end 220a and a tail end 220b. After the insulating sleeve 230 is assembled with the second ring bracket 210, the assembly formed by the two penetrates into the shielding sleeve 220 from the tail end 220b. Correspondingly, the sliding tongue 223 slides in the second guide groove 234 along the direction from the head end 220a to the tail end 220b, and slides to a position where it abuts against the positioning end wall 234a of the second guide groove 234 facing the end where the head end 220a is located. Combining Figure 10 , a positioning portion 113 is further provided on the groove wall of the second installation groove 210a. The positioning portion 113 is provided at a position close to the tail end 220b of the shielding sleeve 220. The positioning portion 113 abuts against one end of the insulating sleeve 230 close to the tail end 220b to cooperate with the sliding tongue 223 to abut against the above-mentioned positioning end wall 234a, and jointly limit the axial position of the insulating sleeve 230. Of course, the axial position of the insulating sleeve 230 relative to the shielding sleeve 220 can also be limited by other means.

[0063] Please refer toFigure 6 In one embodiment, the bracket structure 200 further includes a wire sleeve 240. The wire sleeve 240 abuts against one end of the insulating sleeve 230 near the tail end 220b and is inserted into the shielding sleeve 220. In this embodiment, the positioning portion 113 can indirectly abut against the insulating sleeve 230 by abutting against the wire sleeve 240.

[0064] Please refer to Figure 6 In one embodiment, a through hole 235 is formed at one end of the insulating sleeve 230 near the head end 220a. The through hole 235 allows the terminals 300 carried by the second ring bracket 210 to be exposed, facilitating insertion. The number and distribution position of the through holes 235 correspond to the number and distribution position of the terminals 300 carried by the second ring bracket 210.

[0065] Please refer to Figure 3 In one embodiment, the number of the limiting hooks 112 is at least two. The two limiting hooks 112 are arranged facing each other to cooperate to clamp the bracket structure 200 together. The limiting hook 112 further includes a bump 112c. The bump 112c is provided on a side of the hook rod 112a facing away from the groove wall of the first installation groove 110. The bump 112c is used to contact the bracket structure 200, increasing the resistance to relative movement between the two and reducing the probability of the bracket structure 200 disengaging from the first installation groove 110.

[0066] Please refer to again Figure 11 In one embodiment, the housing 400 includes a housing body 410 and a plurality of cylinders 420. The housing body 410 is sleeved outside the first ring bracket 100. A communication hole 411 is formed in the housing body 410 and is aligned with the bracket structure 200. The plurality of cylinders 420 are provided on the housing body 410 and are aligned with a plurality of terminals 300 directly provided in the first installation groove 110 (i.e., aligned with the first terminals), for the terminals 300 to pass through. The cylinders 420 can support the terminals 300, improving the insertion stability of the terminals 300.

[0067] Please refer to Figure 3 In one embodiment, an installation hole 120 may further be formed in the central area of the first ring bracket 100. A terminal 300 passes through the installation hole 120. Thereby, the space utilization rate of the first ring bracket 100 is further improved.

[0068] Please refer to Figure 11 and Figure 12 In one embodiment, a fixing groove 412 is formed on the inner wall of the housing body 410. The mixed plug-in core assembly 10 further includes a grounding piece. The grounding piece (not shown in the figure, the same below) is installed in the fixing groove 412 and connected to the grounding circuit, so as to be located between the first ring bracket 100 and the housing 400 after the mixed plug-in core assembly 10 is assembled, that is, distributed between the respective terminals 300, for conducting possible leakage current, static electricity, etc. of the terminals 300 to the grounding circuit.

[0069] Please refer to again Figure 3 In one embodiment, part of the terminal 300 can be clamped in the first installation groove 110 through the first opening 111. The first installation groove 110 includes a third limiting portion 114 which is provided on the groove wall of the first installation groove 110. Part of the terminal 300 is provided with a fourth limiting portion (not shown in the figure, the same below). The third limiting portion 114 and the fourth limiting portion are in limiting cooperation, so that the terminal 300 can be stably installed in the first installation groove 110.

[0070] The third limiting portion 114 can be configured as a clamping ring similar to the shape of a snap ring, and the fourth limiting portion can be configured as an annular groove similar to the shape of a ring groove. The clamping ring is clamped with the annular groove, so that the terminal 300 can be stably installed in the first installation groove 110.

[0071] In one embodiment, the mixed mounting ferrule assembly 10 may further include a housing (not shown in the figure, the same below), and the housing is sleeved outside the sleeve 400.

[0072] An embodiment of the present application further provides a connector. The connector includes the mixed mounting ferrule assembly 10 as described in each embodiment. Therefore, the connector also has all the technical effects of the mixed mounting ferrule assembly 10 as described in each embodiment. Moreover, the connector can be used for plugging with another connector including the mixed mounting ferrule assembly 10.
