[0031] 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.

[0032] Connectors are used to transmit power and data signals to connect various systems. During operation, connectors need to be resistant to electromagnetic interference to ensure the stable operation of the electronic systems.

[0033] However, the filter capacitor and ferrite ring 500 used to achieve electromagnetic interference suppression are usually separate from the connector, requiring separate wiring and connection of the filter capacitor and ferrite ring 500, which is difficult when the operating space is limited.

[0034] To address the technical challenge of connecting the aforementioned connector to both the filter capacitor and the magnetic ring 500, the first embodiment of this application provides a connector. (See attached...) Figure 1 and Figure 2 The connector includes a housing assembly 100, a first terminal 200, a second terminal 300, a filter assembly 400, and a magnetic ring 500. The first terminal 200 passes through and is connected to the housing assembly 100. The second terminal 300 passes through and is connected to the housing assembly 100, and the first terminal 200 and the second terminal 300 are spaced apart. The filter assembly 400 is connected to the housing assembly 100, and is disposed between the first terminal 200 and the second terminal 300, and connects the first terminal 200 and the second terminal 300. The magnetic ring 500 is connected to the housing assembly 100 and surrounds at least one of the first terminal 200 and the second terminal 300.

[0035] The first terminal 200 and the second terminal 300 are used to connect to another connector for the transmission of power or data signals.

[0036] The filter component 400 is connected to the housing component 100 to achieve fixation and grounding of the filter component 400. In some embodiments, the filter component 400 is connected to the housing component 100 by bolts to achieve a fixed connection between the filter component 400 and the housing component 100; in some embodiments, the filter component 400 is in contact connection with the housing component 100 to achieve grounding of the filter component 400.

[0037] The filter assembly 400 is electrically connected to both the first terminal 200 and the second terminal 300. In some embodiments, the filter assembly 400 is soldered to the first terminal 200 and the second terminal 300 to achieve electrical connection; in other embodiments, the filter assembly 400 is detachably electrically connected to the first terminal 200 and the second terminal 300 by bolts, respectively.

[0038] In some embodiments, the connector includes at least one magnetic ring 500, which surrounds both the first terminal 200 and the second terminal 300; in other embodiments, the connector includes at least two magnetic rings 500, at least one of which surrounds only the first terminal 200 and at least one of which surrounds only the second terminal 300.

[0039] In some embodiments, the magnetic ring 500 is connected to the housing assembly 100 to secure the magnetic ring 500.

[0040] The magnetic ring 500 is used to suppress sudden current changes and can also convert electromagnetic interference into heat and dissipate it, thereby reducing the intensity of electromagnetic interference. The filter assembly 400 is connected to the first terminal 200 and the second terminal 300 and grounded to absorb transient voltage changes, such as surge voltages, between the first terminal 200, the second terminal 300, and the shielding part of the housing assembly 100, to balance the potential difference, thereby reducing the local magnetic field strength, preventing insulation breakdown caused by arc discharge, and improving the reliability of the connector. At the same time, the filter assembly 400 can also guide high-frequency interference from the first terminal 200 or the second terminal 300 to the flat part of the housing assembly 100 to improve the electromagnetic compatibility of the connector.

[0041] Firstly, in the above embodiments, by incorporating the filter component 400 and the magnetic ring 500 into the connector, the connector integrates functions such as suppressing current and voltage surges and resisting electromagnetic interference, making the connector more reliable and effective in power and data signal transmission. Simultaneously, it avoids the need for additional steps to install the magnetic ring 500 and filter capacitor within the confined space of the device, thus reducing the number of components that need to be connected when using the connector. This ensures connector performance while reducing the difficulty of device installation.

[0042] Secondly, it is understandable that, to maintain relative independence, the first terminal 200 and the second terminal 300 need to be spaced apart. In the above embodiment, by placing the filter component 400 between the first terminal 200 and the second terminal 300 to fully utilize the space between them, the impact on the connector's dimensions perpendicular to the connector insertion direction Z caused by accommodating the filter component 400 is reduced. This allows the connector to adapt to even smaller spaces while still providing electromagnetic interference immunity. Especially when this connector is used in an electric vehicle control system, since it integrates the filter component 400 and the magnetic ring 500 and provides electromagnetic interference immunity, it is better suited to the relatively confined space requirements of electric vehicle control systems. The insertion direction Z is the direction indicated by arrow Z in the attached diagram.

[0043] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The housing assembly 100 includes a connector 110, a first shield 120, and a second shield 130. A first terminal 200 and a second terminal 300 are respectively disposed through the connector 110. A filter assembly 400 is disposed on one side of the connector 110 and connected to the connector 110. A magnetic ring 500 is disposed on the side of the connector 110 near the filter assembly 400 and connected to the connector 110. A portion of the first shield 120 is disposed on the side of the connector 110 away from the filter assembly 400 and surrounds the first terminal 200. A portion of the first shield 120 is disposed through the connector 110 and connected to the filter assembly 400. A portion of the second shield 130 is disposed on the side of the connector 110 away from the filter assembly 400 and surrounds the second terminal 300. A portion of the second shield 130 is disposed through the connector 110 and connected to the filter assembly 400.

[0044] The first shield 120 and the second shield 130 are grounded after the connector is connected to the matching connector. The portion of the first shield 120 and the second shield 130 surrounding the first terminal 200 and the second terminal 300 is used to form a physical barrier to block the penetration of external electromagnetic fields, while the portion connected to the filter assembly 400 is used to ground the filter assembly 400.

[0045] In some embodiments, the connector 110 is made of plastic.

[0046] In the first aspect, in the above embodiments, since the housing assembly 100 includes a first shield 120 and a second shield 130 for shielding, the material of the plug 110 can be a non-metallic material to reduce the weight of the connector and make the connector have better corrosion resistance and a longer life.

[0047] Secondly, in the above embodiments, the first shield 120 and the second shield 130 are respectively connected to the filter component 400 to provide a grounding path for the filter capacitor, further reducing the number of components in the connector, improving the integration of the connector, and reducing the size of the connector.

[0048] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The connector 110 includes a base 111 and a support 112. A first terminal 200, a second terminal 300, a first shield 120, and a second shield 130 pass through and are connected to the base 111. A magnetic ring 500 is connected to the side of the base 111 near the filter assembly 400. The support 112 is disposed between the base 111 and the filter assembly 400 and connects the base 111 and the filter assembly 400 respectively. The support 112 is disposed between the first terminal 200 and the second terminal 300. A portion of the magnetic ring 500 is located between the filter assembly 400 and the base 111.

[0049] Specifically, the portion of the filter assembly 400 connected to the side of the support 112 away from the base 111 is spaced apart from the base 111, and the portion of the magnetic ring 500 is disposed within the space formed by the spaced apart filter assembly 400 and base 111.

[0050] In the above embodiment, by providing a support portion 112 to increase the distance between the filter component 400 and the base 111 along the insertion direction Z, and forming a space between the filter component 400 and the base 111 for placing the magnetic ring 500, the magnetic ring 500 and the filter component 400 are arranged along the insertion direction Z of the connector, thereby reducing the size of the connector perpendicular to the insertion direction Z, so that the connector can adapt to a smaller space while having anti-electromagnetic interference function.

[0051] In some embodiments, the filter assembly 400 and the support portion 112 are connected by bolts.

[0052] In some embodiments, the support portion 112 and the first terminal 200 are spaced apart so that a portion of the magnetic ring 500 can be disposed between the support portion 112 and the first terminal 200; in some embodiments, the support portion 112 and the second terminal 300 are spaced apart so that a portion of the magnetic ring 500 can be disposed between the support portion 112 and the second terminal 300.

[0053] In some embodiments, please refer to Figure 5 The support portion 112 has a connecting groove 113 on the side opposite to the base portion 111, and the filter assembly 400 covers the connecting groove 113; the first shield 120 includes a first shield portion 121 and a first abutment portion 122. The first shield portion 121 is disposed on the side of the base 111 opposite to the support portion 112 and surrounds the first terminal 200. The first abutment portion 122 is connected to the side of the first shield portion 121 near the base 111 and passes through the base 111 and the support portion 112. A portion of the first abutment portion 122... The second shield 130 is disposed in the connecting groove 113 and abuts against the filter assembly 400; the second shield 130 includes a second shield 131 and a second abutting part 132. The second shield 131 is disposed on the side of the base 111 away from the support part 112 and surrounds the second terminal 300. The second abutting part 132 is connected to the side of the second shield 131 near the base 111 and passes through the base 111 and the support part 112. A portion of the second abutting part 132 is disposed in the connecting groove 113 and abuts against the filter assembly 400.

[0054] In some embodiments, after the first abutting part 122 and the second abutting part 132 are connected to the filter component 400, they elastically deform in the direction away from the filter component 400. Under the action of elastic potential energy, the first abutting part 122 and the second abutting part 132 apply elastic force to the filter component 400 to achieve abutment with the filter component 400.

[0055] Specifically, the filter assembly 400 is bolted to the support portion 112. The filter assembly 400 continuously applies pressure to the first abutment portion 122 and the second abutment portion 132, and the first abutment portion 122 and the second abutment portion 132 continuously apply elastic force to the filter assembly 400, so that the connection between the first abutment portion 122 and the second abutment portion 132 and the filter assembly 400 can be maintained continuously.

[0056] In some embodiments, the first abutting portion 122 and the second abutting portion 132 each have a flange, which is folded into the connecting groove 113 and extends toward the filter assembly 400 in a direction away from the bottom wall of the connecting groove 113, so as to generate elastic deformation under the pressure of the filter assembly 400.

[0057] The first contact portion 122 and the second contact portion 132 are used to connect with the filter assembly 400 so that the filter assembly 400 can be grounded through the first shield 120 and the second shield 130.

[0058] The first shielding portion 121 surrounds the first terminal 200 to serve as a physical barrier to the first terminal 200, and the second shielding portion 131 surrounds the second terminal 300 to serve as a physical barrier to the second terminal 300.

[0059] In some embodiments, please refer to Figure 4 The first shield 120 also includes a first pin portion 123, which is connected to the first abutment portion 122 on the same side of the first shield 121. The first pin portion 123 passes through the base 111 and is partially exposed on the side of the base 111 near the support portion 112. The exposed portion can be used as a contact to connect with the housing of the device to which the connector is applicable, so that the first shield 120 is grounded. Similarly, the second shield 130 also includes a second pin portion 133, which is connected to the second abutment portion 132 on the same side of the second shield 131. The second pin portion 133 passes through the base 111 and is partially exposed on the side of the base 111 near the support portion 112. The exposed portion can be used as a contact to connect with the housing of the device to which the connector is applicable, so that the second shield 130 is grounded.

[0060] In the above embodiment, by providing a first abutting part 122 and abutting part 132 on the first shielding member 120 and the second shielding member 130 respectively, so as to abut against the filter component 400 respectively, the connection between the filter component 400 and the first shielding member 120 and the second shielding member 130 is maintained, making the grounding of the filter component 400 more reliable.

[0061] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 7 The connector also includes a cover plate 800, and a seal 700 is embedded in the plug-in 110. The seal 700 seals the connection between the plug-in 110 and the cover plate 800. The cover plate 800 is connected to the side of the first pin portion 123 and the second pin portion 133 opposite to the base 111. The seal 700 can reduce the possibility of corrosion of the first pin portion 123 and the second pin portion 133, thereby improving the reliability of the connector.

[0062] In some embodiments, please refer to Figure 6 and Figure 10 The connector 110 also includes a first elastic portion 114 and a second elastic portion 115. The first elastic portion 114 is connected to the side of the base 111 near the support portion 112. The first elastic portion 114 can approach the first terminal 200 and generate elastic deformation. The first elastic portion 114 can be disposed between the first terminal 200 and the magnetic ring 500 and abut against the magnetic ring 500. The second elastic portion 115 is connected to the side of the base 111 near the support portion 112. The second elastic portion 115 can approach the second terminal 300 and generate elastic deformation. The second elastic portion 115 can be disposed between the second terminal 300 and the magnetic ring 500 and abut against the magnetic ring 500.

[0063] In some embodiments, please refer to Figure 6 The connector 110 includes a plurality of first elastic portions 114. Parts of the plurality of first elastic portions 114 are disposed on the side of the first terminal 200 away from the second terminal 300, and parts of the plurality of first elastic portions 114 are disposed between the first terminal 200 and the second terminal 300. The first elastic portions 114 can deform toward the first terminal 200 and generate elastic potential energy.

[0064] When installing the magnetic ring 500, the first elastic portion 114 can move closer to the first terminal 200 so that the first elastic portion 114 and the first terminal 200 can be simultaneously inserted into the magnetic ring 500. After the magnetic ring 500 is installed in place, under the action of elastic potential energy, the first elastic portion 114 deforms in a direction away from the first terminal 200 to abut against the inner surface of the magnetic ring 500, thereby limiting the displacement of the magnetic ring 500 in the deformation direction of the first elastic portion 114. At the same time, the static friction force generated by the abutment between the first elastic portion 114 and the magnetic ring 500 can limit the displacement of the magnetic ring 500 in the direction perpendicular to the deformation direction of the first elastic portion 114.

[0065] Firstly, in some embodiments, please refer to Figure 5 The connector 110 includes a plurality of second elastic portions 115. Parts of the plurality of second elastic portions 115 are disposed on the side of the second terminal 300 away from the first terminal 200. Parts of the plurality of second elastic portions 115 are disposed between the second terminal 300 and the first terminal 200. The second elastic portions 115 can deform toward the second terminal 300 and generate elastic potential energy.

[0066] When installing the magnetic ring 500, the second elastic portion 115 can move closer to the second terminal 300 so that the second elastic portion 115 and the second terminal 300 can be simultaneously inserted into the magnetic ring 500. After the magnetic ring 500 is installed in place, under the action of elastic potential energy, the second elastic portion 115 deforms in a direction away from the second terminal 300 to abut against the inner surface of the magnetic ring 500, thereby limiting the displacement of the magnetic ring 500 in the deformation direction of the second elastic portion 115. At the same time, the static friction force generated by the abutment between the second elastic portion 115 and the magnetic ring 500 can limit the displacement of the magnetic ring 500 in the direction perpendicular to the deformation direction of the second elastic portion 115.

[0067] In the above embodiments, by providing the first elastic part 114 and the second elastic part 115, the displacement of the magnetic ring 500 in the direction perpendicular to the connector insertion direction Z can be limited, so as to fix the magnetic ring 500, reduce the possibility of the magnetic ring 500 loosening when the connector is in a vibration environment, and improve the connection reliability of the connector.

[0068] In some embodiments, please refer to Figure 6 and Figure 10 The connector 110 further includes a first limiting portion 116, a third elastic portion 117, a second limiting portion 118, and a fourth elastic portion 119. The first limiting portion 116 is connected to the side of the first elastic portion 114 opposite to the base 111, and the first limiting portion 116 can connect to the side of the magnetic ring 500 opposite to the base 111, thus limiting the magnetic ring 500. The third elastic portion 117 is connected to the base 111 and is spaced apart from the first limiting portion 116. The magnetic ring 500 is disposed between the first limiting portion 116 and the third elastic portion 117, and the side of the magnetic ring 500 facing the base 111 can connect to the third elastic portion 117. Part 117 can push the magnetic ring 500 toward the first limiting part 116; the second limiting part 118 is connected to the side of the second elastic part 115 away from the base 111, and the second limiting part 118 can be connected to the side of the magnetic ring 500 away from the base 111 and limit the magnetic ring 500; the fourth elastic part 119 is connected to the base 111, and the fourth elastic part 119 is spaced apart from the second limiting part 118. The magnetic ring 500 is disposed between the second limiting part 118 and the fourth elastic part 119, and the side of the magnetic ring 500 facing the base 111 can be connected to the fourth elastic part 119. The fourth elastic part 119 can push the magnetic ring 500 toward the second limiting part 118.

[0069] In the first aspect, in the above embodiment, by providing the first limiting part 116 and the second limiting part 118, after the magnetic ring 500 is installed in place, the maximum displacement of the magnetic ring 500 in the connector insertion direction Z can be limited by contacting the surface of the magnetic ring 500 away from the base 111.

[0070] Secondly, it is understood that the distances between the first limiting portion 116 and the second limiting portion 118 and the base 111 along the insertion direction Z of the connector may be greater than the maximum dimension of the magnetic ring 500 along the insertion direction Z of the connector. In the above embodiment, by providing a third elastic portion 117 spaced apart from the first limiting portion 116 along the insertion direction Z and a fourth elastic portion 119 spaced apart from the second limiting portion 118 along the insertion direction Z in the base 111, the surface of the magnetic ring 500 facing away from the base 111 can always be in contact with the first limiting portion 116 and the second limiting portion 118, thereby limiting the displacement of the magnetic ring 500 in the axial direction, reducing the possibility of the magnetic ring 500 loosening in a vibrating environment of the connector, and improving the connection reliability of the connector.

[0071] Thirdly, in the above embodiment, after the first terminal 200 and the magnetic ring 500 are installed in place, that is, when the first elastic part 114 is located between the first terminal 200 and the magnetic ring 500, the first elastic part 114 is simultaneously limited by the first terminal 200 and the magnetic ring 500 in a direction perpendicular to the insertion direction Z. It loses the deformation space away from the first terminal 200 and becomes a rigid structure. The first limiting part 116 cannot be removed from one side of the magnetic ring 500, thereby further restricting the displacement of the magnetic ring 500 along the insertion direction Z, making the positioning of the magnetic ring 500 more stable. In other words, the first terminal 200 can cooperate with the first elastic part 114 and the first limiting part 116 to participate in limiting the magnetic ring 500 along the insertion direction Z.

[0072] Similarly, when the second terminal 300 and the magnetic ring 500 are installed in place, i.e., the second elastic part 115 is located between the second terminal 300 and the magnetic ring 500, the second elastic part 115 is simultaneously limited by the second terminal 300 and the magnetic ring in a direction perpendicular to the insertion direction Z. It loses the deformation space away from the second terminal 300 and becomes a rigid structure. The second limiting part 118 cannot be removed from one side of the magnetic ring 500, thereby further restricting the displacement of the magnetic ring 500 along the insertion direction Z, making the positioning of the magnetic ring 500 more stable. In other words, the second terminal 300 can cooperate with the second elastic part 115 and the second limiting part 118 to participate in limiting the magnetic ring 500 along the insertion direction Z.

[0073] In some embodiments, the first limiting part 116 and the second limiting part 118 are both provided with guide surfaces on the side away from the base 111. When the magnetic ring 500 moves toward the base 111, after the guide surfaces come into contact with the magnetic ring 500, the magnetic ring 500 can generate a component force perpendicular to the insertion direction Z on the first limiting part 116 and the second limiting part 118, so that the first limiting part 116 can move closer to the first terminal 200, the first elastic part 114 can deform closer to the first terminal 200, the second limiting part 118 can move closer to the second terminal 300, and the second elastic part 115 can deform closer to the second terminal 300, thereby reducing the installation difficulty of the magnetic ring 500.

[0074] In some embodiments, the third elastic portion 117 is a cantilever structure connected to the base 111. One end of the third elastic portion 117 is connected to the base 111, and the other end can elastically deform away from the first limiting portion 116. When the magnetic ring 500 contacts the other end, the other end can release elastic potential energy to push the magnetic ring 500 toward the first limiting portion 116, so that the magnetic ring 500 is connected to the first limiting portion 116.

[0075] In some embodiments, the fourth elastic portion 119 is a cantilever structure connected to the base 111. One end of the fourth elastic portion 119 is connected to the base 111, and the other end can elastically deform away from the second limiting portion 118. When the magnetic ring 500 contacts the other end, the other end can release elastic potential energy to push the magnetic ring 500 toward the second limiting portion 118, so that the magnetic ring 500 is connected to the second limiting portion 118.

[0076] In some embodiments, please refer to Figure 8 , Figure 9 and Figure 11 The filter assembly 400 includes a circuit board 410, a first filter capacitor 420, and a second filter capacitor 430. The circuit board 410 includes a body 411, a first contact 412, a second contact 413, and a third contact 414. The body 411 is connected to the housing assembly 100. The first contact 412 is disposed on the body 411 and connected to the first terminal 200. The second contact 413 is disposed on the body 411 and connected to the second terminal 300. The third contact 414 is disposed on the body 411 and connected to the housing assembly 100. One end of the first filter capacitor 420 is connected to the first contact 412, and the other end of the first filter capacitor 420 is connected to the third contact 414. One end of the second filter capacitor 430 is connected to the second contact 413, and the other end of the second filter capacitor 430 is connected to the third contact 414.

[0077] Specifically, the third contact 414 is used for grounding.

[0078] In some embodiments, the third contact 414 is connected to the first abutting portion 122 of the first shield 120 and the second abutting portion 132 of the second shield 130, so that the first filter capacitor 420 and the second filter capacitor 430 can be grounded through the third contact 414.

[0079] In some embodiments, at least one bolt passes through the third contact 414 and connects to the support portion 112.

[0080] Firstly, in the above embodiments, by setting up the circuit board 410 and connecting the first filter capacitor 420, the second filter capacitor 430 and the circuit board 410 in advance, when assembling the connector, it is only necessary to connect the filter component 400 to the first terminal 200, the second terminal 300, the first shield 120 and the second shield 130 respectively, without having to connect the first filter capacitor 420 and the second filter capacitor 430 separately, thus simplifying the assembly difficulty of the connector.

[0081] Secondly, in the above embodiments, by setting the circuit board 410, the structure of the filter component 400 can be made more reasonable and the integration is higher, so that it has a smaller size, thereby enabling the filter component 400 to be set between the first terminal 200 and the second terminal 300, thereby reducing the size of the connector in the direction perpendicular to the insertion direction Z.

[0082] In some embodiments, please refer to Figure 11 The filter assembly 400 also includes a third filter capacitor 440, the two ends of which are connected to the first contact 412 and the second contact 413 respectively.

[0083] In the above embodiment, by setting a third filter capacitor 440 and connecting the third filter capacitor 440 to the first contact 412 and the second contact 413 respectively, so that the two ends of the third filter capacitor 440 are connected to the first terminal 200 and the second terminal 300 respectively, the filter component 400 can not only suppress common-mode interference but also suppress differential-mode interference, thereby further improving the reliability of the connector.

[0084] In some embodiments, please refer to Figure 6 and Figure 8 The filter assembly 400 also includes a first connector 450 and a second connector 460. The first connector 450 connects the first contact 412 and the first terminal 200, and at least one magnetic ring 500 is disposed between the first connector 450 and the housing assembly 100. The second connector 460 connects the second contact 413 and the second terminal 300, and at least one magnetic ring 500 is disposed between the second connector 460 and the housing assembly 100.

[0085] Specifically, the first connector 450 is disposed on the side of the magnetic ring 500 away from the base 111, and the second connector 460 is disposed on the side of the magnetic ring 500 away from the base 111.

[0086] In some embodiments, the first connector 450 is riveted to the first terminal 200, and a bolt in the connector passes through the first connector 450 to connect the bolt and the first contact 412, so that the first filter capacitor 420 can be electrically connected to the first terminal 200 through the first connector 450; the second connector 460 is riveted to the second terminal 300, and a bolt in the connector passes through the second connector 460 to connect the bolt and the second contact 413, so that the second filter capacitor 430 can be electrically connected to the second terminal 300 through the second connector 460.

[0087] Firstly, in the above embodiments, by setting the first connector 450 and the second connector 460, the filter component 400 is electrically connected to the first terminal 200 and the second terminal 300 respectively, thereby reducing the assembly difficulty of the connector.

[0088] Secondly, in the above embodiments, by defining the positional relationship between the first connector 450, the second connector 460 and the magnetic ring 500, the filter capacitor and the magnetic ring 500 can be arranged along the insertion direction Z, thereby reducing the impact on the size of the connector perpendicular to the connector insertion direction Z caused by setting the filter component 400 and the magnetic ring 500, so that the connector can adapt to a smaller space while having anti-electromagnetic interference function.

[0089] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 The magnetic ring 500 includes a first magnetic ring 510 and a second magnetic ring 520, the first magnetic ring 510 surrounding the first terminal 200 and connected to the housing assembly 100, the second magnetic ring 520 surrounding the second terminal 300 and connected to the housing assembly 100; and / or, the magnetic ring 500 includes a third magnetic ring 530, the third magnetic ring 530 surrounding the first terminal 200 and the second terminal 300 and connected to the housing assembly 100.

[0090] Specifically, in some embodiments, please refer to Figure 8 and Figure 12 The magnetic ring 500 includes a first magnetic ring 510 and a second magnetic ring 520. The first magnetic ring 510 surrounds the first terminal 200 and is connected to the housing assembly 100. The second magnetic ring 520 surrounds the second terminal 300 and is connected to the housing assembly 100. That is, the first magnetic ring 510 and the second magnetic ring 520 are differential mode magnetic rings. Figure 8 This is a partial perspective view; the portion of the magnetic ring 500 that is obscured is shown as a dashed line in this view.

[0091] The first magnetic ring 510 abuts against the first elastic portion 114 located on the side of the first terminal 200 away from the second terminal 300 and the first elastic portion 114 located on the side of the first terminal 200 close to the second terminal 300, respectively; the second magnetic ring 520 abuts against the second elastic portion 115 located on the side of the second terminal 300 away from the first terminal 200 and the second elastic portion 115 located on the side of the second terminal 300 close to the first terminal 200, respectively.

[0092] In the above embodiment, by providing differential mode magnetic rings, namely the first magnetic ring 510 and the second magnetic ring 520, respectively for the first terminal 200 and the second terminal 300, differential mode interference is suppressed and the impedance to normal differential mode signals is low, making it more suitable for application scenarios where differential mode interference is the main issue. This can improve the reliability of the connector in application scenarios where differential mode interference is the main issue.

[0093] Specifically, in some embodiments, please refer to Figure 9 and Figure 13 The magnetic ring 500 includes a third magnetic ring 530, which surrounds the first terminal 200 and the second terminal 300 and is connected to the housing assembly 100. That is, the third magnetic ring 530 is a common-mode magnetic ring. Figure 9 This is a partial perspective view; the portion of the magnetic ring 500 that is obscured is shown as a dashed line in this view.

[0094] The third magnetic ring 530 abuts against the first elastic portion 114 on the side of the first terminal 200 away from the second terminal 300 and the second elastic portion 115 on the side of the second terminal 300 away from the first terminal 200.

[0095] In the above embodiment, by setting common-mode magnetic rings, i.e., third magnetic rings 530, for the first terminal 200 and the second terminal 300 respectively, common-mode interference can be suppressed, the common-mode radiation of the line itself can be reduced, the impedance to normal differential-mode signals is lower, and it is more suitable for application scenarios where common-mode interference is the main problem. This can improve the reliability of the connector in application scenarios where common-mode interference is the main problem.

[0096] Specifically, in some embodiments, the connector 110 includes a first magnetic ring 510 and a second magnetic ring 520, as well as a third magnetic ring 530. The third magnetic ring 530 is disposed on one side of the first magnetic ring 510 and the second magnetic ring 520 along the insertion direction Z. That is, the connector 110 includes both differential mode magnetic rings and common mode magnetic rings.

[0097] In the above embodiments, by simultaneously providing differential-mode magnetic rings and common-mode magnetic rings (i.e., first magnetic ring 510, second magnetic ring 520, and third magnetic ring 530) for the first terminal 200 and the second terminal 300, the connector's anti-interference types are made more comprehensive, improving the anti-interference capability of the connector and the entire circuit. This ensures stable transmission of normal signals while effectively reducing the impact of external interference on the device and reducing the device's own electromagnetic radiation, making the connector more adaptable to complex electromagnetic environments and giving it better reliability in such environments.

[0098] In order to suppress common-mode interference, it can reduce the common-mode radiation of the line itself to the outside, and has a lower impedance to normal differential-mode signals, making it more suitable for application scenarios where common-mode interference is the main problem. It can improve the reliability of the connector in application scenarios where common-mode interference is the main problem.

[0099] In some embodiments, please refer to Figure 7 The connector also includes a communication terminal 600, which is inserted into both the filter assembly 400 and the housing assembly 100 through the connector 110.
