[0002] In-vehicle Ethernet is widely used between various electronic control units (ECUs), sensors, and entertainment devices within a vehicle, undertaking the important task of high-speed signal transmission and providing a solid communication foundation for the realization of various intelligent functions in automobiles.

[0003] In related technologies, terminals are currently mostly fixed by spot welding. Although this can achieve a stable connection, high temperatures can burn the surface plating of the parts, affecting the product's appearance. Since the plating is crucial for corrosion resistance, damage to it makes the parts susceptible to corrosion in complex environments such as humidity and salt spray, thus affecting the terminal's conductivity and mechanical properties, leading to performance degradation and unstable signal transmission. Furthermore, the terminal design has shortcomings: low strength and susceptibility to deformation affect the stability of the electrical connection. The mating of male and female terminals cannot effectively reduce vibration; vibrations during vehicle operation can cause connection instability and poor contact, affecting the quality of electrical signal transmission.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] In related technologies, terminals are currently mostly fixed by spot welding. Although this can achieve a stable connection, high temperatures can burn the surface plating of the parts, affecting the product's appearance. Since the plating is crucial for corrosion resistance, damage to it makes the parts susceptible to corrosion in complex environments such as humidity and salt spray, thus affecting the terminal's conductivity and mechanical properties, leading to performance degradation and unstable signal transmission. Furthermore, the terminal design has shortcomings: low strength and susceptibility to deformation affect the stability of the electrical connection. The mating of male and female terminals cannot effectively reduce vibration; vibrations during vehicle operation can cause connection instability and poor contact, affecting the quality of electrical signal transmission.

[0024] The following is for reference. Figures 1-4 A plug-in assembly according to an embodiment of the present invention is described.

[0025] like Figures 1-4 As shown, the connector assembly for a vehicle according to the present invention includes a first terminal 11 and a second terminal 12. The first terminal 11 has a connector cavity 1111, within which a connector is formed. The first terminal 11 provides an insertion space for a mating member of the second terminal 12 through the connector cavity 1111. The second terminal 12 is provided with a mating member that can be inserted into the connector cavity 1111 and engage with the connector to establish an electrical path for signal or power transmission.

[0026] The connector assembly also includes a first housing 13 and / or a second housing 14.

[0027] At least a portion of the second housing 14 is inserted into the second terminal 12. The first housing 13 is used to cover the cable connected to the first terminal 11 and can be inserted into the first terminal 11. The first housing 13 can protect the cable, prevent the cable from being damaged by external environmental factors, and extend the service life of the cable; furthermore, the first housing 13, through its insertion connection with the first terminal 11, further enhances the connection stability between the cable and the first terminal 11, ensuring the reliability of electrical signal transmission. At least a portion of the second housing 14 is inserted into the second terminal 12. The second housing 14 is also used to cover the cable connected to the second terminal 12 and can be inserted into the second terminal 12. Its function is similar to that of the first housing 13, providing protection for the cable and enhancing the connection stability between the cable and the second terminal 12, ensuring the normal operation of the electrical connection.

[0028] The first housing 13 and the first terminal 11 are axially limited. A specific limiting connection exists between the first housing 13 and the first terminal 11, ensuring relative positional accuracy by restricting their relative movement in the axial direction, thereby guaranteeing the stability of the electrical connection. Therefore, the connector assembly according to the present invention eliminates the spot welding fixation in related technologies between the first housing 13 and the first terminal 11, adopting an axial limiting connection, which improves the overall quality of the product, reduces the risk of component corrosion, and extends the service life of the connector assembly. The second housing 14 and the second terminal 12 are axially limited. Similar to the connection method between the first housing 13 and the first terminal 11, the second housing 14 and the second terminal 12 are axially limited, also eliminating the need for spot welding fixation between the second housing 14 and the second terminal 12, which helps to extend the overall service life of the connector assembly.

[0029] At least one of the connector and the second terminal 12 is provided with an elastic beam 1121. One end of the elastic beam 1121 is connected to the connector or the second terminal 12, and the other end of the elastic beam 1121 is a free end that can move radially relative to the connector or the second terminal 12. The elastic beams 1121 are configured to be at least two spaced apart in the circumferential direction, and a guide groove is formed between two adjacent elastic beams 1121. By providing the elastic beams 1121, the structural strength of the connector or the second terminal 12 is enhanced. Furthermore, the elastic beams 1121 can provide a certain amount of elastic deformation during the insertion process, making the mating part of the second terminal 12 more smoothly inserted into the insertion cavity 1111 of the first terminal 11, reducing insertion resistance. After the insertion is completed, the elastic force of the elastic beams 1121 can maintain a tight contact between the connector and the mating part, enhancing the stability of the connection, thereby ensuring continuous and reliable electrical or signal transmission.

[0030] At least one of the connector and the second terminal 12 is provided with a guide protrusion 1222. The guide protrusion 1222 protrudes from the surface of the connector cavity 1111 or the second terminal 12 and is adapted to mate with a guide groove. The guide groove plays a guiding role during the insertion process. When the mating part of the second terminal 12 is inserted into the connector cavity 1111 of the first terminal 11, the guide protrusion 1222 moves along the guide groove, guiding the mating part to accurately and smoothly mate with the connector, improving the accuracy and efficiency of the insertion. Furthermore, by engaging with the guide groove, and since the guide protrusion 1222 is located between two adjacent elastic beams 1121, it can limit the relative offset between the first terminal 11 and the second terminal 12 during use, ensuring a continuous and reliable electrical or signal connection.

[0031] According to the connector assembly of the present invention, the axial limiting connection between the first housing 13 and the first terminal 11, and between the second housing 14 and the second terminal 12 eliminates the need for spot welding, thereby improving the overall quality of the product, reducing the risk of corrosion of parts, and extending the service life of the assembly. The elastic beam 1121 and the guide protrusion 1222 provided on the connector and the second terminal 12 enhance the structural strength, make the insertion smoother and reduce resistance, and guide accurate insertion, thereby improving accuracy and efficiency. The elasticity of the elastic beam 1121 can keep the connector and the mating part in close contact, enhance the stability of the connection, and limit the relative offset of the terminals, ensuring a continuous and reliable electrical or signal connection.

[0032] Therefore, the connector assembly according to the present invention improves product quality, reduces the risk of component corrosion and extends service life, while enhancing structural strength, making the connection smoother and more accurate and ensuring a reliable connection.

[0033] It should be noted that, according to the plug-in assembly of the present invention, the axial limiting connection form between the first housing 13 and the first terminal 11, and between the second housing 14 and the second terminal 12 is not strictly limited. Suitable fixing methods such as spot riveting can be used to achieve a reliable axial limiting connection between the two. As long as the relevant requirements such as ensuring electrical connection stability, improving product quality and extending service life can be met, they are all within the protection scope of the present invention.

[0034] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first terminal 11 includes a first terminal housing 111 and a first outer conductor terminal 112. The first terminal housing 111 is arranged in a surrounding manner to form a mating cavity 1111. The first terminal housing 111 is arranged in a surrounding shape, and the internal space formed by its surrounding shape is the mating cavity 1111.

[0035] The first outer conductor terminal 112 is housed within the insertion cavity 1111 and fixedly connected to the first terminal housing 111, ensuring the positional stability of the first outer conductor terminal 112 within the insertion cavity 1111. During subsequent insertion operations and use, it will not easily loosen or shift, thus guaranteeing the reliability of the electrical connection. At least two elastic beams 1121 are formed on the outer peripheral surface of the first outer conductor terminal 112. When the mating component is inserted into the insertion cavity 1111 and contacts the first outer conductor terminal 112, the elastic beams 1121 can undergo elastic deformation, generating a certain amount of elastic force, which makes the insertion process smoother, reduces resistance during insertion, and lowers the difficulty of operation. Simultaneously, the arrangement of at least two elastic beams 1121 not only increases structural strength but also provides elastic force and support from multiple directions, further improving the stability and reliability of the structure.

[0036] According to some embodiments of the present invention, the free end of the elastic beam 1121 forms an inclined section that bends radially inward. The elastic beam 1121 itself has a certain degree of elasticity and can undergo elastic deformation when subjected to external force. The free end of the elastic beam 1121 refers to the end of the elastic beam 1121 that is not connected to other fixed structures and can move freely. The inclined section can first contact the outer surface of the mating part during the insertion of the mating part of the second terminal 12 into the insertion cavity 1111 and provide smooth initial guidance, effectively reducing friction and resistance during insertion, making the insertion action easier and smoother. In addition, the inclined section enables the free end of the elastic beam 1121 to produce a softer and more directional elastic deformation when subjected to radial pressure, ensuring a smooth insertion process and accurate alignment, further improving the convenience and reliability of the insertion operation.

[0037] According to some embodiments of the present invention, such as Figure 2 As shown, the first terminal 11 also includes a first insulator 113 and a first inner conductor 114. The first insulator 113 is housed inside the first outer conductor terminal 112, so that the first outer conductor terminal 112 can provide a certain degree of protection for the first insulator 113. At the same time, the first insulator 113 can also effectively isolate the first outer conductor terminal 112 from the first inner conductor 114, ensuring electrical safety. A insertion hole 1131 is formed on the first insulator 113. The shape and size of the insertion hole 1131 are designed according to the connection requirements with the mating parts.

[0038] The first inner conductor 114 is a component used to transmit electrical signals or current. The first inner conductor 114 is housed in the plug hole 1131 and can be plugged into the mating part of the second terminal 12 to establish an electrical path and realize the transmission of signals or power.

[0039] According to some embodiments of the present invention, such as Figure 2As shown, the first housing 13 includes a first front housing 131 and a first middle housing 132, enabling the first housing 13 to better adapt to different installation and functional requirements. The first front housing 131 is inserted into the first outer conductor terminal 112. The first front housing 131 has a first slot 1311, the shape, size, and position of which are designed according to the mating requirements with the first stop member 1122 inside the first outer conductor terminal 112.

[0040] A first stop member 1122 is provided inside the first outer conductor terminal 112, and it abuts against the first slot 1311 in the insertion direction. After the first front sleeve 131 is inserted into the first outer conductor terminal 112, the first slot 131 on it and the first stop member 1122 provided inside the first outer conductor terminal 112 form a stop engagement in the insertion direction, which can restrict the movement of the first front sleeve 131 in the insertion direction, ensure the accuracy of the position of the first front sleeve 131 in the first outer conductor terminal 112, and thus ensure the structural stability of the entire connector assembly.

[0041] The first middle section shell 132 is connected to the first front section shell 131 and covers the outer periphery of the first inner conductor 114. The first middle section shell 132 is used to cover the outer periphery of the first inner conductor 114, which can provide physical protection for the first inner conductor 114, prevent external environmental factors from damaging the first inner conductor 114, and also help maintain the electrical performance stability of the first inner conductor 114.

[0042] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the second terminal 12 includes a second terminal housing 121, a second outer conductor terminal 122, and a second insulator 123. The second terminal housing 121 is located on the outermost layer of the second terminal 12, providing space for other internal components, and has certain strength and insulation properties.

[0043] The second outer conductor terminal 122 is housed within the second terminal housing 121 and fixedly connected to the second terminal housing 121, ensuring the stable position of the second outer conductor terminal 122 within the second terminal housing 121. The second outer conductor terminal 122 is arranged around the first terminal 11 to form a mating cavity 1221, which provides space for the insertion and mating of the connector of the first terminal 11. When the connector is inserted into the mating cavity 1111, the mating cavity 1221 of the second outer conductor terminal 122 accommodates the connector to meet the requirements of electrical connection.

[0044] The inner wall of the mating cavity 1221 is provided with a guide protrusion 1222, which is adapted to mate with the guide groove on the first terminal 11 connector. It plays a guiding and alignment role during the insertion process, making the insertion smoother and more accurate, and can limit the relative offset of the two terminals in subsequent use.

[0045] The second insulator 123 is housed in the mating cavity 1221. The second insulator 123 is adapted to mate with the plug to provide a stop, and is used to establish and maintain a stable electrical or signal path to achieve reliable signal or power transmission.

[0046] According to some embodiments of the present invention, the guide protrusion 1222 is constructed as an arc-shaped protrusion. An arc-shaped protrusion is a protrusion structure with a smooth curved surface, its surface free of sharp edges and turns. This prevents scratches, wear, or other damage to the surface of the connector when it comes into contact with the connector, thus better protecting the appearance and performance of the connector. It also helps guide the mating parts to accurately and smoothly enter the predetermined mating position, reducing the difficulty of insertion and the risk of component damage caused by misalignment, thereby improving the convenience, success rate, and overall assembly efficiency of the insertion operation.

[0047] According to some embodiments of the present invention, the guide protrusion 1222 is constructed as a strip protrusion extending in the insertion direction, so that the strip protrusion has a clear guiding direction and can provide a continuous and stable guiding effect for the connector during the insertion process, ensuring that the first terminal 11 and the second terminal 12 are accurately aligned along the axial direction and maintain a consistent mating posture, effectively preventing circumferential rotation and radial offset during the insertion process, thereby improving the accuracy, reliability and structural stability of the insertion after connection.

[0048] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the second terminal 12 also includes a second inner conductor 124. The second inner conductor 124 is conductive and is used to contact the first inner conductor 114 for electrical connection.

[0049] The second inner conductor 124 is inserted into the second insulator 123 and is adapted to contact the first inner conductor 114 for electrical connection after the first terminal 11 and the second terminal 12 are inserted. During the insertion operation of the first terminal 11 and the second terminal 12, the first terminal 11 gradually inserts into the mating cavity 1221 of the second terminal 12. As the insertion process proceeds, the first inner conductor 114 within the first terminal 11 also moves accordingly. When fully inserted, the first inner conductor 114 contacts the second inner conductor 124, thereby establishing an electrical connection channel. At this time, current or signals can be transmitted through the first inner conductor 114 and the second inner conductor 124, realizing electrical communication between the first terminal 11 and the second terminal 12.

[0050] According to some embodiments of the present invention, such as Figure 4As shown, the second housing 14 includes a second front housing 141 and a second middle housing 142. The second front housing 141 is inserted into the second outer conductor terminal 122, connecting it to the second terminal 12. The second front housing 141 has a second slot 1411, the size and position of which are such that it can mate with the second stop member 1223 inside the second outer conductor terminal 122.

[0051] A second stop member 1223 is provided inside the second outer conductor terminal 122. The second stop member 1223 and the second slot 1411 form a stop fit in the insertion direction, so that the position of the second front sleeve 141 in the insertion direction is effectively fixed, thereby ensuring the stability and reliability of the connection between the second sleeve 14 and the second terminal 12, and ensuring the long-term stability of the electrical connection between the cable and the second terminal 12.

[0052] The second middle section housing 142 is connected to the second front section housing 141 and covers the outer periphery of the second inner conductor 124. The second middle section housing 142 provides protection for the second inner conductor 124, preventing external factors from damaging the second inner conductor 124, and also helps to maintain the electrical performance stability of the second inner conductor 124, ensuring the quality of signal or power transmission.
