[0017] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0018] Currently, female connectors are designed with fewer than six shielded contact points, which can easily lead to electromagnetic compatibility issues when transmitting higher-speed signals; if the number is more than six, there will be problems with excessive insertion force.

[0019] Whether it's electromagnetic compatibility (EMC) issues caused by fewer than six shielded contact points, or excessive insertion force due to more than six, both can have serious negative impacts on electronic devices. EMC problems can lead to signal instability and data transmission errors. Excessive insertion force not only increases production costs but also shortens the device's lifespan due to operational inconvenience and increased risk of connector damage during daily use.

[0020] Therefore, how to ensure stable signal transmission while avoiding excessive insertion force has become an urgent problem to be solved.

[0021] In view of this, embodiments of this application provide a female connector to solve at least part of the above-mentioned technical problems.

[0022] According to a first aspect of this application, an embodiment of this application provides a female connector. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 This female connector includes a housing 100, an insulating sleeve 200, and bus terminals 300. The housing 100 includes a housing body 110 and a plurality of shielding springs 120 spaced circumferentially along the housing body 110. The shielding springs 120 are located on one side of the housing body 110 in a first direction X and are connected to the housing body 110. At least two shielding springs 120 have different dimensions in the first direction X. The housing 100 also has a first inner cavity 130 that extends through the housing body 110 in the first direction X. The insulating sleeve 200 is housed within the first inner cavity 130 and has a second inner cavity 210 that extends through the insulating sleeve 200 in the first direction X. The bus terminals 300 extend along the first direction X and are housed within the second inner cavity 210.

[0023] It should be noted that this female connector is connected to the male connector. A shielding spring 120 is disposed at the end of the housing body 110 facing the male connector, and the shielding spring 120 extends along the first direction X. When the female connector and the male connector are assembled together, the multiple shielding springs 120 on the female connector contact the mating points in the male connector. Regarding the fact that at least two shielding springs 120 have different dimensions in the first direction X, it can be understood that the multiple shielding springs 120 are at least divided into two batches, mating with the male connector at two different times. This solves the problem of excessive insertion force caused by simultaneous insertion of all shielding springs 120, making the mating process smoother.

[0024] It should be noted that the outer casing 100 is made of metal, such as iron. The outer casing 100 serves to block external interference from entering its interior and prevent internal signal leakage. The insulating sleeve 200 prevents direct contact between the outer casing 100 and the bus terminal 300, avoiding short-circuit faults. The bus terminal 300 enables reliable power / high-current transmission and connection. As the core carrier of current conduction, the bus terminal supports power transmission between the power source (such as a power battery or generator) and the load (such as a motor, electronic control unit, or high-voltage electrical appliance).

[0025] It is understood that the first inner cavity 130 penetrates the shell body 110 along the first direction X, meaning that the outer shell 100 is a hollow structure. The insulating sleeve 200 is installed inside the hollow outer shell 100 and is at least partially in contact with the inner wall of the outer shell 100. The second inner cavity 210 inside the insulating sleeve 200 is used to accommodate the bus terminal 300. It should be noted that the second inner cavity 210 is structurally adapted to the bus terminal 300, and the bus terminal 300 contacts and abuts against the insulating sleeve 200. The number of second inner cavities 210 is the same as the number of bus terminals 300, and the second inner cavities 210 are spaced apart from each other. When the female connector and the male connector are assembled together, the insulating sleeve 200 is completely accommodated in the first inner cavity 130, and the second inner cavity 210 is in communication with the external environment.

[0026] It should be noted that the two ends of the bus terminal 300 are a wiring terminal and a plug-in terminal, respectively. The plug-in terminal faces the male connector and is used to connect with the terminals inside the male connector; the wiring terminal connects to the wire 500 (described below), thereby enabling the signal on the wire 500 to be transmitted to the bus terminal 300 and then to the male connector. In this embodiment, the bus terminal 300 is made of metal.

[0027] As can be seen from the above technical solution, this embodiment sets the multiple shielding springs 120 on the outer shell 100 into at least two structures with different sizes in the first direction X, so that the shielding springs 120 contact the male connector in batches, effectively reducing the insertion force during assembly and making the mating process of the female connector and the male connector smoother; at the same time, the metal outer shell 100 can block external interference and prevent internal signal leakage, the insulating sleeve 200 can prevent the outer shell 100 from short-circuiting with the bus terminal 300, and the bus terminal 300 ensures reliable power / high current transmission. Overall, it achieves multiple technical effects such as low insertion force assembly, stable transmission, anti-interference, and short circuit prevention.

[0028] In some embodiments, please refer to Figure 1 and Figure 4 The shell body 110 includes two first sidewalls 1111 and two second sidewalls 1112. The two first sidewalls 1111 are arranged opposite each other along the second direction Y, and the two second sidewalls 1112 are arranged opposite each other along the third direction Z. The two first sidewalls 1111 and the two second sidewalls 1112 are alternately connected to form a hollow structure. The internal space of the hollow structure is part of the first inner cavity 130. That is, the shell body 110 can be a cuboid structure.

[0029] Existing HMTD (High Speed-Modular Twisted-pair Data) connectors on the market only have 6 shielded contact points, which can easily lead to EMC (Electromagnetic Compatibility) problems when transmitting higher-speed signals. To solve this problem, in this embodiment, the first sidewall 1111 is connected to at least three shielding springs 120 on the side facing the first direction X, and the second sidewall 1112 is connected to at least one shielding spring 120 on the side facing the first direction X. That is, the first sidewall 1111 has at least three shielding springs 120 connected to the side facing the male connector, and the second sidewall 1112 has at least one shielding spring 120 connected to the side facing the male connector. In other words, this embodiment provides at least three shielding springs 120 on the first sidewall 1111 and at least one shielding spring 120 on the second sidewall 1112 of the shell body 110, so that the total number of shielding springs 120 reaches at least eight. Compared with similar products on the market with only 6 shielding contact points, this significantly increases the number of shielding contact points, effectively optimizes electromagnetic compatibility, reduces the generation of electromagnetic interference-related problems during high-speed signal transmission, and ensures the stability and reliability of high-speed signal transmission.

[0030] Furthermore, at least two of the shielding springs 120 connected to the first sidewall 1111 have different dimensions in the first direction X. This allows these shielding springs 120 to make contact with the mating points of the male connector in batches. While increasing the number of shielding contact points to optimize electromagnetic compatibility, it further avoids the problem of excessive insertion force caused by the increased number of shielding springs 120, thus balancing the stability of high-speed signal transmission and the smoothness of connector mating.

[0031] In some examples, please refer to Figure 4 The first sidewall 1111 has four shielding springs 120 spaced apart, and the second sidewall 1112 has one shielding spring 120, meaning there are a total of ten shielding springs 120 on this female connector. At least two of the four shielding springs 120 on the first sidewall 1111 have different dimensions in the first direction X. It can be understood that the four shielding springs 120 on the first sidewall 1111 are sequentially designated as the first spring, second spring, third spring, and fourth spring (not marked in the diagram). The first and fourth springs have the same dimensions in the first direction X, the second and third springs have the same dimensions in the first direction X, and the first and second springs have different dimensions. The first spring can be longer than the second spring, or shorter than the second spring. Furthermore, the shielding springs 120 on the two opposing second sidewalls 1112 have the same dimensions in the first direction X, but the dimensions of the shielding springs 120 on the second sidewall 1112 and the shielding springs 120 on the first sidewall 1111 in the first direction X can be different. That is, the shielding spring 120 on the first sidewall 1111 can be longer than the shielding spring 120 on the second sidewall 1112, or the shielding spring 120 on the first sidewall 1111 can be shorter than the shielding spring 120 on the second sidewall 1112.

[0032] This embodiment can further optimize electromagnetic compatibility by significantly increasing the number of shielded contact points, ensuring stable high-speed signal transmission. It can also avoid excessive insertion force by using 120 batches of shielded spring contacts, while taking into account the smoothness of connector mating. This achieves a dual optimization of improved EMC performance and ease of assembly.

[0033] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4The end of the outer shell 100 facing the male connector needs to be inserted into the male connector for mating. To prevent the shielding spring 120 from being deformed during mating, the outer shell 100 in this embodiment also includes a guide 160 and a connector 170. The guide 160 is located on the side of the shielding spring 120 facing away from the shell body 110 and is spaced apart from the multiple shielding springs 120. It is understood that the guide 160 is located on the side of the multiple shielding springs 120 facing the male connector and does not contact the shielding springs 120. When the female connector and male connector are mated, the guide 160 first contacts the male connector, providing guidance for the shielding springs 120 and preventing the shielding springs 120 from entering the male connector at an angle, thereby avoiding deformation of the shielding springs 120.

[0034] It should be noted that the shielding spring 120 is bent at one end toward the guide 160, specifically, bent toward the external environment, so as to contact the shielding shell of the male connector. Furthermore, the bent portion of the shielding spring 120 toward the guide 160 needs to be housed within the first inner cavity 130, while the remaining portion can be located in the external environment. In other words, the guide 160 can protect the shielding spring 120 without affecting the contact between the shielding spring 120 and the shielding shell of the male connector.

[0035] The connector 170 extends along the first direction X. One end of the connector 170 is connected to the junction of the first sidewall 1111 and the second sidewall 1112, and the other end of the connector 170 is connected to the guide 160. It is understood that the junction of the first sidewall 1111 and the second sidewall 1112 forms a corner, and the connector 170 connects to the corner, located on the side of the corner facing the male connector, and is connected to the guide 160. That is, the connector 170 connects the guide 160 to the housing body 110, while simultaneously protecting the shielding spring 120 within the area between the guide 160 and the housing body 110. It should be noted that there are at least two connectors 170. When there are two connectors 170, any pair of diagonally opposite corners of the four corners of the shell body 110 can be provided with connectors 170. When there are three connectors 170, any three corners of the shell body 110 can be provided with connectors 170. When there are four connectors 170, all four corners of the shell body 110 are provided with connectors 170.

[0036] To facilitate exposure of the end of the insulating sleeve 200 facing the male connector, an opening 180 is formed in the housing 100. The opening 180 passes through the guide 160 along the first direction X and communicates with the first inner cavity 130. That is, the insulating sleeve 200 can be exposed through the opening 180, while the second inner cavity 210 can communicate with the external environment through the opening 180. It should be noted that the size of the opening 180 is smaller than the size of the end of the insulating sleeve 200 facing the male connector, which prevents the insulating sleeve 200 from detaching from the first inner cavity 130 from the opening 180; it limits the insulating sleeve 200 to entering and exiting only from the end of the housing 100 away from the male connector.

[0037] As can be seen from the above technical solution, this embodiment can provide guidance for the mating process of the female connector through the cooperation of the guide 160 and the connector 170, and can prevent the shielding spring 120 from entering the male connector at an angle, and protect the shielding spring 120 from being deformed by the push; it can also prevent the insulating sleeve 200 from coming out of the first inner cavity 130 from the opening 180.

[0038] In some embodiments, please refer to Figure 1 and Figure 5 The end of the shell body 110 away from the shielding spring 120 and the outer wall of the insulating sheath 200 form a first receiving cavity 140. It is understood that there is a gap between the part of the shell body 110 away from the shielding spring 120 and the outer wall of the insulating sheath 200.

[0039] The female connector also includes an outer rivet ring 400, a portion of which is housed within a first receiving cavity 140 and connected to the housing body 110. The outer rivet ring 400 has a third inner cavity 410 extending through it along a first direction X. The end of the insulating sleeve 200 away from the shielding spring 120 is housed within the third inner cavity 410. It should be noted that the end of the outer rivet ring 400 facing the male connector is looped around the end of the insulating sleeve 200 away from the male connector. In addition, the outer riveting ring 400 has a variable diameter structure. The minimum cross-sectional dimension of the outer riveting ring 400 in the second direction Y is smaller than the minimum cross-sectional dimension of the insulating sleeve 200 in the second direction Y. Thus, the outer riveting ring 400 always presses the insulating sleeve 200 toward the shielding spring 120. Combined with the guide member 160 limiting the insulating sleeve 200, and the connection between the outer riveting ring 400 and the shell body 110, the insulating sleeve 200 is stably housed in the space enclosed by the outer riveting ring 400 and the outer shell 100. This space is part of the first inner cavity 130.

[0040] In some embodiments, please refer to Figure 1 and Figure 4The structure of the shell body 110 is further refined. Specifically, the shell body 110 includes a first connecting portion 111, a transition portion 112, and a second connecting portion 113. The first connecting portion 111 is formed by two alternating first sidewalls 1111 and two second sidewalls 1112. The transition portion 112 is connected to the side of the first connecting portion 111 opposite to the shielding spring 120. The second connecting portion 113 is connected to the side of the transition portion 112 opposite to the first connecting portion 111. In the plane containing the second direction Y and the third direction Z, the cross-sectional area of ​​the second connecting portion 113 is larger than the cross-sectional area of ​​the first connecting portion 111. The transition portion 112 connects the first connecting portion 111 and the second connecting portion 113, which have different cross-sectional areas. The first inner cavity 130 sequentially penetrates the first connecting portion 111, the transition portion 112, and the second connecting portion 113 along the first direction X. It is understandable that the shell body 110 has a variable diameter structure, and the cross-sectional size of the shell body 110 increases from small to large along the direction from the first connecting part 111 to the second connecting part 113; the end of the transition part 112 away from the first connecting part 111 is inclined in the direction away from the first inner cavity 130 so that it can be connected to the periphery of the second connecting part 113.

[0041] It should be noted that the guide member 160 is located on the side of the shielding spring 120 opposite to the first connecting part 111, and the connector 170 is connected to the first connecting part 111. There is a gap between the second connecting part 113 and the insulating sleeve 200, forming the aforementioned first receiving cavity 140.

[0042] In the first direction X, the outer rivet ring 400 abuts against the transition portion 112 at one end facing the shielding spring 120. When the female connector and the male connector mate, the outer rivet ring 400 moves into the first receiving cavity 140 against the inner wall of the second connecting portion 113 until it abuts against the transition portion 112 of the housing body 110, thereby defining the relative position of the outer rivet ring 400 and the housing body 110. Correspondingly, a space is formed between the housing body 110 and the outer rivet ring 400, and the insulating sleeve 200 is accommodated in this space. The outer rivet ring 400 applies a force to the insulating sleeve 200 toward the guide member 160, and the guide member 160 prevents the insulating sleeve 200 from detaching from the housing body 110.

[0043] In some examples, multiple laser welding points 150 are provided axially in the second connection portion 113, and the second connection portion 113 of the shell body 110 is connected to the outer riveting ring 400 by welding.

[0044] In some embodiments, please refer to Figure 1 and Figure 5The insulating sleeve 200 includes a sleeve body 220 and a limiting part 230, which can be integrally formed. The sleeve body 220 is housed in the first inner cavity 130, and the end of the sleeve body 220 away from the shielding spring 120 is housed in the third inner cavity 410. Together with the inner walls of the second connecting part 113 and the transition part 112 of the shell body 110, the first receiving cavity 140 provides a stable buffer and positioning space for the engagement of the outer riveting ring 400 and the insulating sleeve 200.

[0045] The limiting part 230 is connected to the outer wall of the sheath body 220 and protrudes in a direction away from the second inner cavity 210. It should be noted that there may be multiple limiting parts 230, which are distributed at intervals along the circumferential direction of the outer peripheral wall of the sheath body 220, or are continuously arranged along the circumferential direction of the outer peripheral wall of the sheath body 220.

[0046] The outer rivet ring 400 has a limiting groove 420 adapted to the structure of the limiting part 230. The limiting groove 420 is formed at one end of the outer rivet ring 400 facing the shielding spring 120, and the limiting groove 420 communicates with the third inner cavity 410. The limiting part 230 can be accommodated in the limiting groove 420. In the first direction X, one end of the limiting part 230 abuts against the transition part 112, and the other end of the limiting part 230 abuts against the bottom of the limiting groove 420. It should be noted that the number of limiting grooves 420 is the same as the number of limiting parts 230. When the insulating sleeve 200 is assembled with the outer rivet ring 400, the limiting part 230 is accommodated in the limiting groove 420 to achieve reliable radial positioning, and in the first direction X, it abuts against the transition part 112 and the bottom of the limiting groove 420 in both directions to form a stable axial limiting.

[0047] As can be seen from the above technical solution, the limiting part 230 can enhance axial positioning and further limit the displacement of the insulating sleeve 200 in the space formed by the shell body 110 and the outer rivet ring 400, so as to avoid vibration or movement during long-term use and ensure the terminal docking accuracy; improve assembly consistency, and reduce manual operation error by using the limiting part 230 to be inserted into the limiting groove 420 as a marker.

[0048] In some embodiments, please refer to Figure 1 and Figure 5 The female connector also includes a wire 500, a portion of which is housed within the third inner cavity 410 and electrically connected to a bus terminal 300 located within the second inner cavity 210. It should be noted that the wire 500 in this embodiment is a twisted-pair cable. Therefore, the female connector in this embodiment includes two bus terminals 300, which are spaced apart and electrically connected to the two cores 510 of the wire 500.

[0049] In some embodiments, please refer to Figure 1 and Figure 5 The aforementioned outer rivet ring 400 includes a first shielding member 430 and a rivet member 440. The first shielding member 430 is circumferentially disposed around the outer periphery of the sheath body 220 and housed within the first receiving cavity 140. The first shielding member 430 is fixedly connected to the shell body 110, and the aforementioned limiting groove 420 is formed on its side facing the limiting portion 230. The rivet member 440 is connected to the end of the first shielding member 430 away from the limiting portion 230 and is fastened to the outer periphery of the wire 500 by riveting, thereby achieving reliable fixation between the wire 500 and the outer rivet ring 400.

[0050] In this embodiment, the electromagnetic shielding effect is enhanced by the first shielding component 430, forming a double anti-interference protection with the metal shell 100. The rivet component 440 is used to fasten the twisted pair cable, preventing the wire 500 from being pulled and causing the terminal connection to loosen. At the same time, the positioning of the limiting groove 420 and the limiting part 230 makes the assembly of the wire 500, bus terminal 300 and insulating sheath 200 more integrated, taking into account shielding stability, connection reliability and structural compactness.

[0051] In some embodiments, please refer to Figure 1 and Figure 5 The conductor 500 employs a multi-layered protective structure. Specifically, the conductor 500 includes a conductor core 510, a first insulating member 520, a second shielding member 530, and a second insulating member 540. The conductor core 510 extends along a first direction X. The first insulating member 520 is arranged around the outer periphery of the conductor core 510. The second shielding member 530 is arranged around the outer periphery of the first insulating member 520, and the second insulating member 540 is arranged around a portion of the outer periphery of the second shielding member 530, with a portion of the second insulating member 540 housed within a third inner cavity 410.

[0052] It should be noted that each wire core 510 is wrapped with an insulation layer to achieve insulation isolation between the wire cores 510 and avoid short circuits. The first insulating component 520 wraps two wire cores 510 together. The second shielding component 530, the outer shell 100, and the first shielding component 430 form triple electromagnetic shielding, which greatly reduces internal and external electromagnetic interference and is suitable for high-speed signal transmission. The second insulating component 540 provides protection for the end of the conductor 500. At the same time, through cooperation with the third inner cavity 410, it ensures the sealing and stability of the assembly of the conductor 500 and the outer rivet ring 400, and reduces the impact of environmental factors on the connection parts.

[0053] In some embodiments, please refer to Figure 1 and Figure 5The second shielding member 530 includes an integrally formed fitting portion 531 and a folded portion 532. The fitting portion 531 is disposed around the outer periphery of the first insulating member 520, forming the shielding base of the conductor 500; the folded portion 532 is accommodated within the third inner cavity 410 and abuts against the inner wall of the outer rivet ring 400. In the first direction X, one end of the folded portion 532 is connected to the end of the fitting portion 531 facing the insulating sheath 200, and the other end of the folded portion 532 extends away from the insulating sheath 200, forming a second receiving cavity 533 between the folded portion 532 and the fitting portion 531. The second insulating member 540 is disposed around the outer periphery of the fitting portion 531, and part of the second insulating member 540 is accommodated within the second receiving cavity 533.

[0054] It should be noted that the contact between the folded part 532 and the inner wall of the outer rivet ring 400 allows the second shielding member 530 to form a seamless connection with the shielding system of the first shielding member 430 and the outer shell 100, thereby strengthening the integrity of the triple shielding. The second receiving cavity 533 provides positioning space for the second insulating member 540, preventing the first insulating member 520 and the wire core 510 from shifting. At the same time, it improves the compactness of the assembly between the wire 500 and the outer rivet ring 400. Combined with the fastening effect of the rivet member 440, it further enhances the tensile strength and sealing performance of the connection part.

[0055] In some embodiments, please refer to Figure 1 and Figure 5 The female connector also includes an inner rivet ring 600, which is housed within the second receiving cavity 533. It should be noted that the inner rivet ring 600 supports the folded portion 532. Furthermore, the rivet member 440 rivets to the folded portion 532 on the outer periphery of the inner rivet ring 600, thereby securing the outer rivet ring 400 to the wire 500. The inner rivet ring 600 protects its internal components, such as the first insulation member 520 and the wire core 510, preventing the rivet member 440 from excessively compressing the wire core 510 and thus avoiding any impact on the transmission performance of the wire 500.

[0056] Specifically, the rivet 440 completely encloses the folded part 532, the fitting part 531, the inner rivet ring 600, part of the first insulating part 520 and part of the wire core 510 in the third inner cavity 410.
