Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to a connector and connector assembly. Background Technology

[0002] The electronics industry is undergoing profound transformation amidst the rapid development of 5G communications, portable computing, and wearable devices. Cutting-edge fields such as industrial vision inspection, digital medical imaging, autonomous driving, humanoid robots, drone swarms, and ultra-high-definition display terminals are widely integrating and deeply relying on ultra-high-definition imaging technology, placing stringent demands on both signal transmission rates and device miniaturization. Connectors, as the core interface between high-speed data streams and miniaturized terminal devices, not only need to establish stable, low-loss high-speed transmission channels but also need to provide electromagnetic shielding effectiveness within a limited space.

[0003] To enhance electromagnetic shielding performance, two layers of shielding are installed at the connector wire ends, forming a shielding assembly that surrounds the connector from top to bottom. The overlapping of the upper and lower shielding components presents a challenge. In related technologies, the upper and lower shielding components are typically overlapped using soldering. However, the solder used for soldering is corrosive, and the surface treatment of the workpiece before soldering requires high precision, making it prone to false soldering or detachment, which affects mechanical stability.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0026] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] This application provides a connector and a connector assembly, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0028] According to the first aspect of this application, referring to Figures 1 to 3 One embodiment of this application provides a connector 100 that can be plugged into and mated with a mating connector 200. The connector 100 can be one type of plug connector or receptacle connector, and the mating connector 200 can be the other type of plug connector or receptacle connector. In this embodiment, the connector 100 is a plug connector and the mating connector 200 is a receptacle connector, enabling high-speed signal transmission from cable 51 to a circuit board (not shown).

[0029] Reference Figure 4 and Figure 5The connector 100 may have a first direction X, a second direction Y, and a third direction Z that intersect each other. In this embodiment, the first direction X, the second direction Y, and the third direction Z are mutually perpendicular. The first direction X may be the length direction of the connector 100. The second direction Y may be the width direction of the connector 100. The third direction Z may be the height direction of the connector 100. The connector 100 may include: a first base 1, a first signal terminal 2, a first shield 3, and a second shield 4. The connector 100 may also include a cable assembly 5, which may include at least one cable 51. In this embodiment, there are multiple cables 51, and the multiple cables 51 may be arranged side by side along the first direction X. The cable 51 may include an inner conductor 511, and the inner conductor 511 of the cable 51 may be connected to the first signal terminal 2.

[0030] Specifically, the first base 1 is the insulating main structure of the connector 100. The first base 1 is generally elongated and extends along the first direction X (i.e., the length direction of the connector 100). The first base 1 can be manufactured by processes such as injection molding. The first base 1 can be made of insulating material, such as plastic. Plastics include, for example, liquid crystal polymer (LCP), polyamide (PA), or other high-performance engineering plastics. These materials have excellent heat resistance, dimensional stability, and injection molding performance, meeting the requirements of the connector 100 in high-temperature welding and long-term use environments. The first base 1 is used to support and fix components such as the first signal terminal 2, the first shield 3, and the second shield 4. The first base 1 has opposing upper and lower sides in the third direction Z, as well as peripheral surfaces connecting the upper and lower sides. The first base 1 may also be provided with groove structures and protrusion structures for mating with the first shield 3 and the second shield 4.

[0031] The first signal terminal 2 can be disposed on the first base 1. A portion of the first signal terminal 2 can be encapsulated within the first base 1, i.e., the first signal terminal 2 is encapsulated and fixed within the first base 1 through injection molding, forming an integral structure with the first base 1. One end of the first signal terminal 2 is used to connect to the inner conductor 511 of the cable 51. The first signal terminal 2 and the inner conductor 511 of the cable 51 can be connected by welding, crimping, or other methods. The other end of the first signal terminal 2 can protrude from the first base 1, for elastic contact with the second signal terminal 220 of the mating connector 200 in the mated state, thereby realizing signal transmission.

[0032] The first signal terminal 2 can be made of a conductive material, such as phosphor bronze or beryllium copper alloy, and its surface can be plated with gold or tin to improve conductivity and corrosion resistance. There can be one or more first signal terminals 2. In this embodiment, there are multiple first signal terminals 2, which can be arranged at intervals along the first direction X.

[0033] The first shielding element 3 can be disposed on one side of the first base 1 in the third direction Z, and the second shielding element 4 can be disposed on the opposite side of the first base 1 in the third direction Z. Both the first shielding element 3 and the second shielding element 4 can be made of conductive material, such as stainless steel plate or copper alloy plate, and their surfaces can be plated with nickel or gold to enhance conductivity and corrosion resistance. The first shielding element 3 and the second shielding element 4 can respectively surround the first base 1 from the top and bottom, forming electromagnetic shielding for the internal signal transmission channel of the connector 100, preventing external electromagnetic interference from intruding and internal signal radiation leakage.

[0034] As an example, the first shielding member 3 may include a first shielding body 31 and a first extension 32. The first shielding body 31 may be a plate-like structure of the main body of the first shielding member 3. The first shielding body 31 may be disposed on the side of the first base 1 in the third direction Z, that is, covering the upper surface of the first base 1 in the third direction Z, and mainly playing the role of electromagnetic shielding from above.

[0035] The second shielding element 4 may include a second shielding body 41 and a second extension 42. The second shielding body 41 may be a plate-like structure of the main body of the second shielding element 4. The second shielding body 41 may be disposed on the opposite side of the first base 1 in the third direction Z, that is, covering the lower surface of the first base 1 in the third direction Z, and mainly playing the role of electromagnetic shielding below.

[0036] The first extension 32 can extend from the first shielding body 31 toward the second shielding body 41, that is, from top to bottom. In this embodiment, the first extension 32 can be a tab structure extending downward from the first shielding body 31, and the first extension 32 can be integrally formed from the plate surface of the first shielding body 31 by stamping and bending processes.

[0037] The second extension 42 can extend from the second shielding body 41 toward the first shielding body 31, that is, from bottom to top. In this embodiment, the second extension 42 can be a tab structure extending upward from the second shielding body 41, and the second extension 42 can be integrally formed from the plate surface of the second shielding body 41 by stamping and bending processes.

[0038] The first extension 32 and the second extension 42 are engaged to connect the first shielding member 3 and the second shielding member 4. As an example, the first extension 32 can extend from top to bottom, and the second extension 42 can extend from bottom to top, allowing them to meet and engage in the area of ​​the first base 1. This engagement method is a purely mechanical elastic connection, eliminating the need for soldering. The contact force generated by elastic deformation achieves a reliable connection between the first shielding member 3 and the second shielding member 4, forming both electrical conductivity and mechanical fixation. Replacing traditional soldering with a purely mechanical elastic engagement eliminates the defects associated with soldering, such as corrosion, false soldering, and detachment.

[0039] In this application, a purely mechanical connection between the first extension 32 of the first shielding member 3 and the second extension 42 of the second shielding member 4 is achieved through a snap-fit ​​engagement, avoiding the use of soldering and thus eliminating the potential risks associated with the corrosiveness of solder. This also reduces the surface treatment requirements for the first and second shielding members 3 and 4, avoiding the risk of false soldering or desoldering, improving the contact reliability and mechanical stability of the connector 100, and ensuring reliable connection of the connector 100 during actual use such as flight and vibration. Furthermore, it avoids the risk of thermal damage to adjacent plastic components and signal terminals caused by high welding temperatures, thereby improving the stability of the connector 100's performance and extending its service life. Moreover, the purely mechanical connection also provides good detachability, facilitating the repair and recycling of the connector 100. The mechanical connection can also connect dissimilar materials such as metal and plastic, making it widely applicable. In addition, the first shielding body 31 and the second shielding body 41 are respectively disposed on opposite sides of the first base 1, forming a top-and-bottom enclosing shielding structure, which helps to enhance the electromagnetic shielding effect.

[0040] In some embodiments, refer to Figures 6 to 8 The first base 1 may be provided with a first groove 11. The first groove 11 may be a gap structure that passes through the upper and lower sides of the first base 1 in the third direction Z. At least a portion of the first extension 32 and at least a portion of the second extension 42 may be located within the first groove 11, so that the first extension 32 and the second extension 42 can meet and engage within the first groove 11. The first groove 11 not only provides space for the engagement of the first extension 32 and the second extension 42, but also limits and guides their positions, thereby improving the accuracy and stability of the engagement. During assembly, the first extension 32 and the second extension 42 can be inserted from the upper and lower sides of the first groove 11 respectively, meet within the first groove 11, and engage.

[0041] In this embodiment, the first extension 32 and the second extension 42 can be arranged side by side in the second direction Y. The first extension 32 can be provided with a first protrusion 321, which protrudes towards the second extension 42, that is, the first protrusion 321 protrudes towards the second extension 42 along the second direction Y. The second extension 42 can be provided with a second protrusion 421 corresponding to the first protrusion 321, which protrudes towards the first extension 32, that is, the second protrusion 421 protrudes towards the first extension 32 along the second direction Y. The first extension 32 and the second extension 42 can be interlocked by the first protrusion 321 and the second protrusion 421. Both the first protrusion 321 and the second protrusion 421 can be structures such as bulges or ribs. The first protrusion 321 and the second protrusion 421 can be integrally formed on the surfaces of the first extension 32 and the second extension 42 by processes such as stamping. When the first extension 32 and the second extension 42 meet in the first groove 11, the first extension 32 and the second extension 42 can undergo elastic deformation so that the first protrusion 321 and the second protrusion 421 form a locking and fixing, thereby realizing the elastic contact and mechanical fixing of the first shielding member 3 and the second shielding member 4.

[0042] When the first extension 32 and the second extension 42 are pressed against each other by the protrusions, they undergo elastic deformation, causing the second protrusion 421 to move above the first protrusion 321 in the third direction Z, thereby engaging the first protrusion 321 and the second protrusion 421. This elastic contact force keeps the first extension 32 and the second extension 42 in a continuous pressed state. Even under the influence of environmental factors such as vibration and temperature changes, the contact force fluctuates but does not disappear, improving the reliability of the connection between the first shielding member 3 and the second shielding member 4. The height and shape of the first protrusion 321 and the second protrusion 421 are designed according to the required contact force. The height of the first protrusion 321 and the second protrusion 421 can be from 0.1 mm to 0.3 mm, etc., to generate sufficient contact force.

[0043] In some embodiments, refer to Figure 4At least one of the first extension 32 and the second extension 42 may also be provided with a third protrusion 422. The third protrusion 422 may be a structure that protrudes outward from the first extension 32 and / or the second extension 42 along a first direction X, with a protrusion amount such that when the first extension 32 and / or the second extension 42 are inserted into the first groove 11, the third protrusion 422 can form an interference fit with the inner wall of the first groove 11. An interference fit is a connection method that uses a slight interference in the dimensions of the mating parts to generate friction and fastening force through the elastic deformation of the material. The interference amount can be from 0.02 mm to 0.1 mm, etc., and the specific value is determined according to the material, size, and required fastening force of the mating parts. The interference fit between the third protrusion 422 and the inner wall of the first groove 11 can increase the friction and fastening force between the first extension 32 and / or the second extension 42 and the first groove 11, further improving the firmness of the connection between the first shield 3 and the second shield 4, and preventing the shield from shifting or falling off under vibration or impact conditions.

[0044] In this application, a first protrusion 321 and a second protrusion 421 are provided on the first extension 32 and the second extension 42 to achieve mutual interlocking. Simultaneously, a third protrusion 422 is provided on the extension to interfere with the inner wall of the first groove 11, forming a double fixing mechanism. This results in high and controllable connection strength between the first shield 3 and the second shield 4. Furthermore, the first extension 32 and the second extension 42 are located within the first groove 11, so the interlocking structure does not occupy additional external space, which is beneficial for the miniaturization of the connector 100.

[0045] In some embodiments, the number of first extensions 32 is the same as the number of second extensions 42, and both the number of first extensions 32 and the number of second extensions 42 are one or more. (Refer to...) Figure 4 When there is only one first extension 32 and one second extension 42, the first extension 32 can be positioned close to the middle of the first shield 3 in the first direction X, and the second extension 42 can be positioned close to the middle of the second shield 4 in the first direction X. Positioning the first extension 32 and the second extension 42 in the middle of the connector 100 in the first direction X allows the first shield 3 and the second shield 4 to obtain a balanced fixing force in the middle region, avoiding insufficient bonding force in the middle region due to the connector 100 being too long. When there are multiple first extensions 32 and multiple second extensions 42, these multiple extensions 32 and 42 can be evenly distributed along the first direction X or positioned at key locations based on force analysis to provide multi-point fixing along the entire length of the connector 100, further enhancing the bonding strength of the first shield 3 and the second shield 4, thereby reducing the risk of separation of the first shield 3 and the second shield 4.

[0046] In some embodiments, refer to Figure 4 , Figure 9 and Figure 10 The first shielding member 3 may further include a third extension 33. The second shielding member 4 may further include a fourth extension 43. The number of third extensions 33 and fourth extensions 43 can both be one or more. In this embodiment, the number of third extensions 33 and fourth extensions 43 are both two. The third extensions 33 and fourth extensions 43 can be located at both ends of the connector 100 in the first direction X, near the outer side of the cable assembly 5 in the first direction X. The third extension 33 can be a tab structure extending downward from both ends of the first shielding body 31 near the cable 51. The fourth extension 43 can be a tab structure disposed from both ends of the second shielding body 41 near the cable 51.

[0047] In one embodiment, at least one third extension 33 may be provided with a first slot 331, which may be a square hole (i.e., a through hole), a blind hole, or the like. At least one fourth extension 43 may be provided with a first engaging portion 431 corresponding to the first slot 331, which may be a barb or the like extending obliquely downward from the fourth extension 43. The end of the first engaging portion 431 away from the fourth extension 43 can be inserted into or pass through the first slot 331 and engaged therein, thereby connecting the third extension 33 and the fourth extension 43.

[0048] In another embodiment, at least one third extension 33 may be provided with a first engaging portion 431, which may be a barb or other structure extending obliquely upward from the third extension 33. At least one fourth extension 43 may be provided with a first slot 331 corresponding to the first engaging portion 431, which may be a square hole (i.e., a through hole), a blind hole, or other structure. The end of the first engaging portion 431 away from the third extension 33 can be inserted into or pass through the first slot 331 and engaged therein, thereby connecting the third extension 33 and the fourth extension 43.

[0049] In this application, the first shielding member 3 and the second shielding member 4 are engaged in the middle region in the first direction X by a first extension 32 and a second extension 42, and their end regions in the first direction X are engaged by a third extension 33 and a fourth extension 43. Thus, the connector 100 forms a multi-point connection between the first shielding member 3 and the second shielding member 4 in the first direction X. Even if the connector 100 is long, the bonding strength between the first shielding member 3 and the second shielding member 4 can be ensured, preventing the first shielding member 3 and the second shielding member 4 from separating from the first base 1 and falling off.

[0050] In some embodiments, refer to Figure 4 , Figure 11 and Figure 12 The first shielding member 3 may further include a fifth extension 34. The fifth extension 34 may be a tab structure extending downward from the first shielding body 31. The first base 1 may be provided with a second groove 12. The second groove 12 may be formed on the upper surface of the first base 1, corresponding to the position of the fifth extension 34. At least a portion of the fifth extension 34 may be inserted into the second groove 12, thereby restricting the position of the first shielding member 3 in the first direction X.

[0051] The fifth extension 34 may be provided with a fourth protrusion 341, which can be interference-fitted with the inner wall of the second groove 12. The fourth protrusion 341 can be a structure that protrudes outward from the surface of the fifth extension 34. When the fifth extension 34 is inserted into the second groove 12, the fourth protrusion 341 forms an interference fit with the inner wall of the second groove 12, generating friction and fastening force, and firmly fixing the first shielding member 3 to the first base 1. This fixing method does not require additional fasteners; reliable fixing can be achieved by the interference fit between the fourth protrusion 341 and the inner wall of the second groove 12, further reducing the risk of the first shielding member 3 falling off the first base 1 and realizing the overall structural stability of the connector 100.

[0052] In some embodiments, the number of fifth extensions 34 can be one or more. When there are multiple fifth extensions 34, at least two fifth extensions 34 can be located at both ends of the first shield 3 in the first direction X. By providing fifth extensions 34 at both ends and inserting them into the corresponding second grooves 12 to form an interference fit, the first shield 3 can be securely fixed to the first base 1, thus constraining both ends of the first shield 3 and further improving the reliability of the fixation. This reduces the risk of the first shield 3 falling off the first base 1 due to vibration or impact during the use of the connector 100.

[0053] In some embodiments, refer to Figure 4 and Figure 5 The first shielding member 3 may further include a sixth extension 35. The sixth extension 35 is located on the outer periphery of the first base 1, that is, the sixth extension 35 may extend outward from the edge of the first shielding body 31 and surround the outer periphery of the first base 1. In this embodiment, the sixth extension 35 may be located on at least one side of the first shielding body 31 in the second direction Y.

[0054] The first base 1 may be provided with a fifth protrusion 13, which may be a structure that protrudes outward from the outer periphery of the first base 1. In this embodiment, the fifth protrusion 13 may be located on one side of the first base 1 in the second direction Y, and there are two fifth protrusions 13, which may be distributed at intervals along the first direction X. The sixth extension 35 may be provided with a second snap-fit ​​portion 351, which extends obliquely from the sixth extension 35 toward the first shielding body 31, forming a structure such as barbs that are obliquely inward.

[0055] When the sixth extension 35 is installed onto the first base 1, the second snap-fit ​​portion 351 engages with the fifth protrusion 13 to circumferentially fix the first shield 3 to the first base 1. This snap-fit ​​structure prevents the first shield 3 from detaching from the first base 1 in the third direction Z, thus limiting the first shield 3 in multiple directions and further enhancing the reliability of the connection between the first shield 3 and the first base 1.

[0056] In some embodiments, refer to Figure 4 The second shielding member 4 may further include a seventh extension 44. The number of seventh extensions 44 may be one or more. When there are multiple seventh extensions 44, at least two seventh extensions 44 are located at opposite ends of the second shielding body 41 in the first direction X. The seventh extension 44 may include a first bend 441 and a second bend 442. The first bend 441 extends from the second shielding body 41 towards the first shielding body 31 in the third direction Z, i.e., it bends upwards. The second bend 442 extends from the first bend 441 in the first direction X to the side of the first base 1 facing away from the second shielding body 41, i.e., the second bend 442 continues to bend from the first bend 441 and extends to the upper surface of the first base 1. Through this double-bending structure, the seventh extension 44 can extend from the lower side around the side of the first base 1 to the upper side, forming a covering over the first base 1. This strengthens the circumferential restraint on the second shield 4, further improving the bonding strength between the second shield 4 and the first base 1, and preventing the second shield 4 from falling off the first base 1.

[0057] In this application, the first shielding member 3 and the second shielding member 4 are not only engaged in the middle region by the first extension 32 and the second extension 42, but also engaged in the end region by the third extension 33 and the fourth extension 43; a double fixing mechanism is formed by the engagement of the first protrusion 321 and the second protrusion 421 and the interference fit between the third protrusion 422 and the inner wall of the first groove 11; lateral fixing is formed by the side engagement of the sixth extension 35 and the fifth protrusion 13; and back fixing is formed by the wrapping of the base by the seventh extension 44. The above multiple fixing structures work together to form a three-dimensional fixing network with multiple points, multiple regions, and multiple directions, which greatly improves the overall structural strength of the connector 100.

[0058] In some embodiments, refer to Figure 4 and Figure 5 The cable 51 can be a coaxial cable, etc., and can include, from the inside out, an inner conductor 511, an insulation layer 512, a shielding layer 513, and an outer sheath 514. The inner conductor 511 is the core conductor for signal transmission and can be made of copper or copper alloys. The insulation layer 512 can be arranged around the inner conductor 511 and can be made of a low dielectric constant material such as polytetrafluoroethylene (PTFE). The shielding layer 513 can be a metal braided layer or a metal foil layer arranged around the insulation layer 512, which serves as electromagnetic shielding. The outer sheath 514 is the outermost insulating protective layer.

[0059] The first signal terminal 2 can be electrically connected to the inner conductor 511 through methods such as crimping or soldering. Before connection, the outer sheath 514, shielding layer 513, and insulation layer 512 at the end of the cable 51 need to be peeled off to expose the inner conductor 511, and then the inner conductor 511 is connected to one end of the first signal terminal 2. The other end of the first signal terminal 2 can be exposed from the first base 1, and is used to make elastic contact with the second signal terminal 220 of the mating connector 200 in the mated state to realize the signal transmission path. The signal transmission path can be from the inner conductor 511 of the cable 51 to the first signal terminal 2, then to the second signal terminal 220, and finally to the circuit board.

[0060] The cable assembly 5 also includes a connector 52 for connecting the shielding layer 513 of the cable 51 to the first shielding element 3 and / or the second shielding element 4. At least a portion of the shielding layer 513 of the cable 51 can contact the connector 52, and at least a portion of the connector 52 can contact the first shielding element 3 and / or the second shielding element 4 to form a ground return path. This allows interference signals induced on the shielding layer 513 to return to ground through the connector 52, the first shielding element 3, and the second shielding element 4, thereby suppressing electromagnetic interference and enhancing the electromagnetic shielding performance of the connector 100. Simultaneously, the connector 52, acting as an intermediate bridge, simplifies the connection process between the shielding layer 513 and the shielding elements.

[0061] As an example, connector 52 may include a first conductive layer 521, a sheathing layer 522, and a second conductive layer 523. The first conductive layer 521 may contact the first shielding element 3, and the second conductive layer 523 may contact the second shielding element 4. The first conductive layer 521 and the second conductive layer 523 may be plate-like structures, with the sheathing layer 522 located between the first conductive layer 521 and the second conductive layer 523. A portion of the outer sheath 514 of the cable 51 near the first signal terminal 2 may be removed; this portion may be embedded in the sheathing layer 522, which may be made of, for example, tin, to achieve a reliable electrical connection between the shielding layer 513 and connector 52. Through connector 52, the shielding layer 513 of the cable 51 forms an electrical connection with the first shielding element 3 and / or the second shielding element 4, thereby connecting the shielding layer 513 of the cable 51 to the shielding system of connector 100, forming a complete electromagnetic shielding loop.

[0062] According to the second aspect of this application, referring to Figures 1 to 3 One embodiment of this application provides a connector assembly including a mating connector 200 and a connector 100 as described above. The mating connector 200 is a receptacle connector. The mating connector 200 may include a second base 210, a second signal terminal 220, and a shielding housing 230.

[0063] The second base 210 is the insulating main structure of the mating connector 200. The second base 210 is generally elongated and extends along the first direction X (i.e., the length direction of the mating connector 200). The second base 210 can be manufactured by processes such as injection molding. The second base 210 can be made of an insulating material, such as a plastic. Examples of plastics include liquid crystal polymers (LCP), polyamides (PA), or other high-performance engineering plastics.

[0064] The second signal terminal 220 can be disposed on the second base 210, and one end of the second signal terminal 220 is used to connect to the circuit board. The second signal terminal 220 can be electrically connected to the contact pad of the circuit board by surface mounting, such as soldering or sintering. The other end of the second signal terminal 220 is used to contact the first signal terminal 2 of the connector 100 in the mated state to realize signal transmission.

[0065] The shielding housing 230 can be disposed on the second base 210 and used for connection to the circuit board. The shielding housing 230 can be made of conductive material, such as stainless steel or copper alloy, and covers the outside of the second base 210 to serve as electromagnetic shielding and grounding. The shielding housing 230 can also be provided with solder feet 2304, which are used to solder to the grounding pad on the circuit board to form a grounding path.

[0066] When connector 100 and mating connector 200 are in the mating state, the other end of the second signal terminal 220 contacts the first signal terminal 2, thus establishing the signal transmission channel. Simultaneously, the shielding shell 230 can contact the first shielding element 3 and / or the second shielding element 4, establishing the shielding circuit. Through the contact between the shielding shell 230 and the first shielding element 3 and / or the second shielding element 4, the shielding system of connector 100 and the shielding system of mating connector 200 form a complete grounding circuit, thereby enhancing the overall electromagnetic shielding performance.

[0067] In some embodiments, refer to Figure 2 and Figure 3 The first shielding member 3 may be provided with a second slot 352. The second slot 352 may be provided in the sixth extension 35, and the second slot 352 may be a through hole, blind hole, or other structure. The shielding shell 230 may be provided with a first elastic member 2301. The first elastic member 2301 may be a structure that elastically extends from the wall surface of the shielding shell 230, such as an elastic spring or elastic claw, and may be integrally formed from the wall surface of the shielding shell 230 by a stamping process. The first elastic member 2301 may be provided with a third engaging portion 2302 corresponding to the second slot 352. The third engaging portion 2302 can engage with the second slot 352 to connect the first shielding member 3 to the shielding shell 230. During the insertion process, the first elastic member 2301 of the shielding shell 230 is compressed and undergoes elastic deformation. When it reaches a preset position, the third engaging portion 2302 springs into the second slot 352 to form a snap-fit ​​fixation. This snap-fit ​​method ensures reliable contact in the mating state and provides positioning and holding force to prevent the first shield 3 from accidentally disengaging from the shield housing 230 under vibration conditions.

[0068] The number of second slots 352 can be one or more. In this embodiment, the number of second slots 352 is multiple. The first shielding member 3 is provided with two second slots 352 at both ends in the first direction X, and the two second slots 352 located at the same end can be distributed at intervals along the second direction Y. Correspondingly, the shielding shell 230 is provided with two first elastic members 2301 at both ends in the first direction X, and the two first elastic members 2301 located at the same end can be distributed at intervals along the second direction Y.

[0069] In some embodiments, refer to Figure 2 and Figure 3The first shielding member 3 may be provided with a sixth protrusion 353, which may be disposed on the sixth extension 35. The shielding shell 230 may be provided with a second elastic member 2303 corresponding to the sixth protrusion 353. The second elastic member 2303 may be a structure that elastically extends from the wall surface of the shielding shell 230, such as an elastic spring or elastic claw, and may be integrally formed from the wall surface of the shielding shell 230 by a stamping process. The first shielding member 3 and the shielding shell 230 may be elastically connected through the sixth protrusion 353 and the second elastic member 2303. In the inserted state, the sixth protrusion 353 may press against the second elastic member 2303, causing the second elastic member 2303 to undergo elastic deformation, thereby forming an elastic contact force and achieving reliable electrical contact between the two.

[0070] The number of sixth protrusions 353 can be one or more. In this embodiment, the number of sixth protrusions 353 is multiple. The multiple sixth protrusions 353 can be spaced apart along the first direction X. Correspondingly, the multiple second elastic members 2303 are spaced apart along the first direction X.

[0071] The snap-fitting method between the second slot 352 and the third snap-fitting part 2302, and the elastic connection method between the sixth protrusion 353 and the second elastic member 2303, can be used individually or in combination. When used in combination, they can provide double elastic contact, further improving the connection reliability of the shielding system.

[0072] As an example, the working principle of the connector assembly in this application embodiment is as follows.

[0073] When connector 100 and mating connector 200 are in a separated state, the first signal terminal 2 of connector 100 is exposed from the first base 1, and the second signal terminal 220 of mating connector 200 is also exposed from the second base 210.

[0074] When it is necessary to mate connector 100 with mating connector 200, align the mating end of connector 100 with the mating end of mating connector 200, and then push connector 100 into mating connector 200 in the mating direction.

[0075] During the mating process, the first signal terminal 2 of connector 100 contacts the second signal terminal 220 of mating connector 200. The second signal terminal 220 can undergo elastic deformation to form an elastic contact, thereby establishing a signal transmission path. Simultaneously, the first shield 3 of connector 100 contacts the shield shell 230 of mating connector 200. Specifically, the third snap-fit ​​portion 2302 of the first elastic member 2301 of shield shell 230 snaps into the second slot 352 of the first shield 3, achieving a snap-fit ​​connection. The second elastic member 2303 of shield shell 230 elastically abuts against the sixth protrusion 353 of the first shield 3, achieving an elastic connection.

[0076] Once connector 100 and mating connector 200 are fully engaged, the signal is transmitted from the inner conductor 511 of cable 51 through the first signal terminal 2 to the second signal terminal 220, and then to the circuit board. Simultaneously, interference signals on the shielding layer 513 of cable 51 are transmitted via connector 52 to the first shielding component 3 and the second shielding component 4, and then via the shielding shell 230 to the ground of the circuit board, achieving effective electromagnetic shielding and grounding return.

[0077] When it is necessary to separate connector 100 from mating connector 200, pull connector 100 in the opposite direction to the mating direction to disengage the first signal terminal 2 from the second signal terminal 220, and at the same time disengage the first shield 3 from the shielding shell 230.

[0078] Throughout the entire mating and disassembly process, mechanical connections (clamping or interference fit) are used between the first shielding component 3 and the second shielding component 4, between the first shielding component 3 and the first base 1, between the second shielding component 4 and the first base 1, and between the first shielding component 3 and the shielding shell 230, instead of soldering. Therefore, connection failures due to poor soldering will not occur. Furthermore, the mechanical connection method gives the connector 100 good detachability, facilitating maintenance and recycling.
