Description

Technical Field

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

[0002] To ensure good assemblability and maintainability of electronic devices such as mobile phones, tablets, and laptops, modular designs are typically employed. Taking a camera module as an example, a modular camera connects to the motherboard or other modules via a BTB (board-to-board) connector. To achieve superior high dynamic range (HDR), the transmission rate of the Mobile Industry Processor Interface (MIPI) needs to be increased. For connector assemblies, good shielding performance is required to prevent interference from the radio frequency antenna on the camera module. However, the size of shielded connector assemblies has reached a bottleneck in its evolution, failing to meet the trend towards product miniaturization. Summary of the Invention

[0003] This application provides a connector assembly and an electronic device. Through structural optimization, the size of the connector assembly can be effectively reduced, thereby reducing the board area occupied.

[0004] A first aspect of this application provides a connector assembly, which includes a first connector and a second connector that are mated together. The first connector includes a first body, a first terminal, and a first shield. The first terminal is fixedly disposed on the first body, and the first shield is located on the outer periphery of the first body. The second connector includes a second body, a second terminal, and a second shield. The second terminal is fixedly disposed on the second body, and the second shield is located on the outer periphery of the first body. The first terminal and the second terminal are both arranged in two rows spaced apart in a first direction. The rows of first terminals are spaced apart in a second direction, and the rows of second terminals are spaced apart in a second direction. The first shield and the second shield are in elastic contact and electrically connected, and the elastic force of the elastic contact is formed along the insertion direction. The first direction and the second direction are different directions that intersect the insertion direction.

[0005] In this way, the first and second shielding components are elastically connected in the insertion direction, and elastically abut against each other based on the elastic force formed along the insertion direction, thereby constructing a reliable shielded grounding link on the outer periphery of the connector assembly. This effectively reduces the space occupied by the shielded grounding link in the first direction. Overall, based on the connector assembly architecture provided in this application embodiment, the size is effectively reduced, thereby enabling reasonable control of the assembly board space occupied by the first connector side and the second connector. While meeting the shielding performance requirements, it also meets the design requirements of the trend towards product miniaturization.

[0006] Based on the first aspect, this application also provides a first implementation of the first aspect: the first body is a frame with a receiving portion, two rows of first terminals are disposed on the frame, the solder feet of the two rows of first terminals overlap with the receiving portion in the insertion direction, and the solder feet of the two rows of first terminals have a first distance in the first direction; the second body includes an outer frame body and an island portion, the island portion is located within the outer frame body, an annular recess is provided between the island portion and the outer frame body, two rows of second terminals are disposed within the annular recess, the solder feet of the two rows of second terminals overlap with the island portion in the insertion direction, and the solder feet of the two rows of second terminals have a second distance in the first direction. The island portion can be inserted into the receiving portion of the first body, and the frame of the first body can be inserted into the annular recess of the second body. In this way, the soldering position formed by the solder feet of the two rows of first terminals on the first connector side tends to be located close to the center of the first body, that is, the solder feet of the two rows of first terminals are soldered inside the first body at a first distance. Compared with the prior art, where the solder feet of the two rows of first terminals require two soldering distances to be soldered outside the first body, this saves one soldering distance and reduces the space occupied by the first connector in the first direction. Similarly, it can also effectively reduce the space occupied by the second connector in the first direction.

[0007] It should be noted that the first spacing between the solder feet of the two rows of first terminals in the first direction and the second spacing between the solder feet of the two rows of second terminals in the first direction are both set to meet the welding process requirements. Ensuring the spacing can avoid welding defects.

[0008] Based on the first embodiment of the first aspect, this application also provides a second embodiment of the first aspect: the first shielding member includes a spring portion and a first welding portion. The first welding portion is disposed around the outer periphery of the first body. The spring portion is connected to the first welding portion and protrudes from the first welding portion toward the second connector side. The second shielding member is fitted onto the outer periphery of the second body and presses against the spring portion to form an elastic force. Here, both the spring portion and the first welding portion are made of metal material to achieve electrical connection between the shielding members on both sides. When the first shielding member and the second shielding member are inserted and mated, they can press against the metal spring portion to produce adaptive deformation. The deformed elastic portion has good structural stability and better electrical connection reliability.

[0009] For example, the first shielding member can be integrally formed by a stamping process, such as, but not limited to, stamping from a sheet of stainless steel.

[0010] Based on the second implementation of the first aspect, this application also provides a third implementation of the first aspect: multiple spring contacts can be configured, with the multiple spring contacts spaced apart from the first welding portion. Overall, the stability and reliability of the grounding shielding circuit are further improved through multi-point interconnection.

[0011] For example, the spring portion extends circumferentially along the first weld portion, and the distance between the extended ends of two adjacent spring portions is 1.2mm-1.5mm.

[0012] Based on the second or third embodiment of the first aspect, this application also provides a fourth embodiment of the first aspect: the first welding portion includes a plurality of protrusions for forming solder feet, the protrusions protruding from the first welding portion in a direction opposite to the second connector, and the plurality of protrusions are spaced apart in the first welding portion. That is, solder feet adapted to the first grounding pad are formed by the protrusions protruding in a direction opposite to the second connector. In this way, as long as the outer surfaces of each protrusion are flush, the overall welding accuracy can be effectively improved and the welding reliability of each solder foot can be guaranteed.

[0013] Based on the second, third, or fourth implementation of the first aspect, this application also provides a fifth implementation of the first aspect: the first connector further includes two first protective fittings, which are respectively disposed at both ends of the first body in a second direction; the first shield is spaced apart from the first protective fittings. With this configuration, based on the separate design architecture of the first shield and the first protective fittings, for different scenarios with the same interconnection function, different structural sizes of the first shield can be configured for the same first body 11 to adapt to board-side routing limitations. Overall, this effectively reduces the assembly cost of devices with the same interconnection function.

[0014] In practical applications, the thickness of the first shielding component is less than the thickness of the first protective fitting. This design, based on the relatively thin spring section, allows for reasonable control of the positive force generated by the compressive deformation during insertion and fastening, thus achieving low yield.

[0015] Based on the first embodiment of the first aspect, this application also provides a sixth embodiment of the first aspect: the first shielding member includes a flexible conductive material and a first welding portion, the first welding portion is disposed around the outer periphery of the first body, the flexible conductive material is located on the side of the first welding portion facing the second connector, and the second shielding member is fitted onto the outer periphery of the second body and presses against the flexible conductive material to form an elastic force. In this way, based on the ability of the flexible conductive material to continuously form electromagnetic shielding around the outer periphery of the first body, and based on the deformability of the flexible conductive material, the first shielding member and the second shielding member can be elastically matched, constructing a grounding shielding circuit with better isolation, further improving the electromagnetic shielding effect.

[0016] For example, the flexible conductive material can be conductive foam or conductive gel.

[0017] Based on the first embodiment of the first aspect, this application also provides a seventh embodiment of the first aspect: a first shielding member is disposed around the outer periphery of a first body using a flexible conductive material, and a second shielding member is fitted onto the outer periphery of a second body and presses against the flexible conductive material to form an elastic force. Similarly, based on the ability of the flexible conductive material to continuously form electromagnetic shielding around the outer periphery of the first body, and based on the deformability of the flexible conductive material, the first and second shielding members can be elastically matched to construct a grounding shielding circuit with better isolation, further improving the electromagnetic shielding effect.

[0018] For example, the flexible conductive material can be conductive foam or conductive gel.

[0019] Based on the first, second, third, fourth, fifth, sixth, or seventh implementation of the first aspect, this application also provides an eighth implementation of the first aspect: the solder feet of the two rows of first terminals are staggered in the second direction. This facilitates the arrangement of injection molding operations and reduces process implementation costs.

[0020] Based on the eighth implementation of the first aspect, this application also provides a ninth implementation of the first aspect: the two rows of first terminals are staggered in the second direction, and correspondingly, the two rows of second terminals are staggered in the second direction. That is to say, the entire bodies of the two rows of first terminals are staggered, resulting in relatively low design and manufacturing costs.

[0021] Based on the eighth or ninth embodiment of the first aspect, this application also provides a tenth embodiment of the first aspect: the second connector further includes two second protective fittings, which are respectively disposed at both ends of the island in the second direction. This effectively avoids damage during assembly with the first connector side.

[0022] Based on the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth implementations of the first aspect, this application also provides an eleventh implementation of the first aspect: the second body includes multiple process openings that penetrate the second body in the insertion direction, and each process opening corresponds to a second terminal; in the projection plane of the second terminal in the insertion direction, the projection of the solder foot end of the second terminal is located within the projection of the process opening. With this configuration, after the terminal injection molding is completed, it can be cut through the corresponding process openings to form solder foot ends that meet the spacing requirements.

[0023] In practical applications, the size of the process opening corresponds to the size of the corresponding solder pad. For example, the process opening of the solder pad 232 corresponding to the second power terminal is larger than the process opening of the solder pad corresponding to the second signal terminal.

[0024] Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, or the fifth embodiment of the first aspect, or the sixth embodiment of the first aspect, or the seventh embodiment of the first aspect, or the eighth embodiment of the first aspect, or the ninth embodiment of the first aspect, or the tenth embodiment of the first aspect, or the eleventh embodiment of the first aspect, this application also provides a twelfth embodiment of the first aspect: the second shielding member includes an outer shell, a pressing part, and a second welding part. The outer shell is a cylindrical structure including a first end and a second end disposed opposite to each other. The pressing part is connected to the first end of the outer shell to make contact and electrical connection with the first shielding member in the insertion direction. The second welding part is connected to the second end of the outer shell. With this configuration, a reliable electrical connection with the first shielding member in the insertion direction is achieved based on the pressing part located at the first end of the outer shell. Overall, it has good structural stability.

[0025] Based on the twelfth embodiment of the first aspect, this application also provides a thirteenth embodiment of the first aspect: the pressing portion is bent inward from the first end of the housing. While achieving a reliable electrical connection in the insertion direction, the dimensions can be further rationally controlled, effectively reducing the assembly board space occupied by the first connector and the second connector.

[0026] Based on the thirteenth embodiment of the first aspect, this application also provides a fourteenth embodiment of the first aspect: the second shielding member includes two inner covering portions, which are respectively disposed at both ends of the outer frame body of the second body in the second direction. The inner covering portions are bent downward from the inner edge of the pressing portion and can cover the inner wall of the outer frame body. In this way, by having the two inner covering portions correspond one-to-one with the corresponding positions of the outer frame body, the corresponding protective function is provided to avoid damage during assembly with the first connector.

[0027] Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, or the fifth embodiment of the first aspect, or the sixth embodiment of the first aspect, or the seventh embodiment of the first aspect, or the eighth embodiment of the first aspect, or the ninth embodiment of the first aspect, or the tenth embodiment of the first aspect, or the eleventh embodiment of the first aspect, this application also provides a twelfth embodiment of the first aspect: an assembly positioning pair is provided between the second shield and the second body, the assembly positioning pair being used to limit the second shield and the second body in the insertion direction. Based on the assembly positioning pair, relative limiting of the two in the insertion direction can be achieved.

[0028] For example, in the inner covering portion of the second shield and the outer frame body of the second body, a limiting groove is provided on one and a limiting block is provided on the other. The limiting block and the bottom of the limiting groove form an assembly positioning pair. During assembly, when the second shield and the outer frame body are fastened together, the bottom of the limiting groove can abut against the limiting block of the outer frame body, thereby limiting the second shield and the second body in the insertion direction. This improves the operability during assembly, has better assembly processability, and the corresponding structure does not occupy the width dimension space of the second connector.

[0029] A second aspect of this application provides an electronic device including a circuit board and a device module. The device module is connected to the circuit board via a connector assembly, which is the connector assembly described above. Based on this connector assembly, while meeting good shielding requirements, the assembly space occupied by the connector can be reasonably controlled, meeting the design requirements of product miniaturization.

[0030] For example, electronic devices can be mobile phones, tablets, laptops, etc. Attached Figure Description

[0050] This application provides a connector assembly implementation scheme that can effectively reduce the board area occupied, and provides good technical support for meeting the trend of product miniaturization design requirements while meeting the shielding performance requirements.

[0051] In the architectural design of electronic devices such as mobile phones, tablets, and laptops, modular design can achieve good assemblability and maintainability. Examples include, but are not limited to, battery modules and camera modules. As the demand for product miniaturization increases, the integration of component layouts also increases, leading to more significant shielding interference between components. For connector assemblies, it is necessary to balance good shielding performance with reasonable size control.

[0052] Taking a camera module as an example, modular cameras connect to the motherboard or other modules via BTB connectors. To achieve higher dynamic range and HDR capabilities, the MIPI transmission rate needs to be increased. When the signal frequency overlaps with the operating frequency band of the RF antenna, signal reception and processing will be affected by RF signal interference. However, the shielding of the two mating connectors abuts laterally, resulting in a large width dimension, which creates a bottleneck in the size evolution of connector components and cannot meet the trend of product miniaturization.

[0053] In addition, due to the limitations of the shielding structure configuration, the spacing between the solder feet of the two rows of terminals and the corresponding outer peripheral shielding parts must meet the welding process requirements, which also occupies the width dimension.

[0054] Based on this, embodiments of this application provide a connector assembly, including a first connector and a second connector that are mated together, both having terminals fixedly disposed on their insulating bodies. After mating, the contact portion of the first terminal on the first connector side abuts and mates with the contact portion of the second terminal on the second connector side, establishing a corresponding communication relationship. Based on the mating assembly relationship, one can be a plug connector, and the other can be a socket connector.

[0055] In this embodiment, the first connector includes a first body, a first terminal, and a first shield. The first terminal is fixedly disposed on the first body, which is made of insulating material, and the first shield is located on the outer periphery of the first body. The second connector includes a second body, a second terminal, and a second shield. The second terminal is fixedly disposed on the second body, which is made of insulating material, and the second shield is located on the outer periphery of the second body. The mating terminals (first terminal and second terminal) on the first connector and the second connector are arranged in two rows spaced apart in a first direction, and each row of terminals is spaced apart in a second direction. Here, the first direction and the second direction are different directions within a plane intersecting the insertion direction.

[0056] The solder feet of the first terminal are located on the surface of the first body opposite to the second connector in the insertion direction. Two rows of solder feet of the first terminal extend towards each other and have a first spacing in the first direction. The solder feet of the second terminal are located on the surface of the second body opposite to the first connector in the insertion direction. Two rows of solder feet of the second terminal extend towards each other and have a second spacing in the first direction.

[0057] The first and second shielding components are in elastic contact and electrically connected, and the elastic force forming the elastic contact is along the insertion direction. Here, "insertion direction" refers to the direction in which the first connector and the second connector are inserted and mated, and is limited to a single insertion direction; that is, it includes both the direction in which the first shielding component is inserted and mated towards the second shielding component and the direction in which the second shielding component is inserted and mated towards the first shielding component.

[0058] In this way, the first and second shielding components are elastically connected in the insertion direction, and achieve elastic abutment adaptation based on the elastic force formed along the insertion direction, so as to build a reliable shielded grounding link on the outer periphery of the connector assembly, which can effectively reduce the space occupation of the shielded grounding link in the first direction. Overall, based on the connector assembly architecture provided by the embodiments of this application, the size can be effectively reduced, thereby reasonably controlling the assembly board space occupied by the first and second connectors, and meeting the design requirements of product miniaturization while meeting the shielding performance requirements.

[0059] To better understand the technical solution and effects of this application, specific embodiments will be described in detail below with reference to the accompanying drawings. Please refer to... Figure 1A , Figure 1B , Figure 2A and Figure 2B ,in, Figure 1A This is a schematic diagram illustrating the assembly relationship of a connector assembly provided in an embodiment of this application. Figure 1B This is a schematic diagram of a connector assembly provided in an embodiment of this application. Figure 2A for Figure 1AAA section view, Figure 2B for Figure 1B BB cross-sectional view.

[0060] The connector assembly 100 includes a mating first connector 10 and a mating second connector 20. The first connector 10 and the second connector 20 are respectively disposed on two devices to be connected for mating; for example, but not limited to, the first connector 10 is connected to a camera module, and the second connector 20 is connected to a motherboard. Figure 1A As shown, along the direction indicated by the arrow, the first connector 10 can be inserted into and fitted onto the second connector 20, forming as shown in the figure. Figure 1B The connector assembly 100 shown.

[0061] When the first connector 10 and the second connector 20 are inserted and fitted together, electrical and signal connections can be achieved between the two devices to be connected. Figure 2A As shown, along the direction indicated by the arrow, the contact portions of each first terminal on the first connector 10 side (contact portion 121 of the first signal terminal and contact portion 131 of the first power terminal) respectively abut and mate with the contact portions of each second terminal on the second connector 20 side (contact portion 221 of the second signal terminal and contact portion 231 of the second power terminal), forming as shown in the figure. Figure 2B The electrical connections shown are as follows. Without loss of generality, the first connector 10 here is a plug connector, and the corresponding second connector 20 is a socket connector. The first connector 10 and the second connector 20 are in the form of interlocking strips, and the specific length, width and proportions can be adjusted adaptively according to the actual product configuration.

[0062] In this embodiment, the first connector 10 includes a first body 11, a first signal terminal 12, a first power terminal 13, and a first shielding member 14. Please refer to [other documentation / reference]. Figure 3 and Figure 4 ,in, Figure 3 Figure 1 shows a schematic diagram of the overall structure of the first connector. Figure 4 for Figure 3 A schematic diagram showing the first connector from another perspective. Figure 3 The first connector 10 shown is formed from its mating side with the mating second connector 20 to clearly illustrate the arrangement of the power terminals and signal terminals.

[0063] like Figure 3 As shown, the first body 11 serves as the terminal fixing base structure for the first connector 10 and is made of insulating material. The first signal terminal 12 and the first power terminal 13 are first terminals fixed to the first body 11. Exemplarily, the first terminals can be injection molded integrally with the first body 11. Please refer to [further details omitted]. Figure 5 The image is Figure 3The diagram shows a partial exploded view of the first connector.

[0064] Along the width direction X (first direction) of the first connector 10, two rows of first terminals are spaced apart. Along the length direction Y (second direction) of the first connector 10, rows of first terminals (first signal terminals 12 and first power terminals 13) are arranged sequentially at intervals, with the first power terminals 13 located on both sides of the plurality of first signal terminals 12.

[0065] In a specific implementation, the first signal terminal 12 and the first power terminal 13 are respectively provided with one-to-one correspondence with the second terminals (second signal terminal and second power terminal) on the side of the second connector 20. The number of the first signal terminal 12 and the first power terminal 13 can be determined according to the overall design requirements of the connector assembly, and is not limited in this embodiment.

[0066] In other specific implementations, the first power terminal 13 and the second power terminal can be selectively configured. In other words, for connector assemblies that do not require power supply, only mating signal terminals can be configured; this application embodiment does not impose limitations.

[0067] In this embodiment, the first body 11 has an overall rectangular frame structure to achieve good load-bearing stability. Two rows of first terminals are arranged on the long side of the rectangular first body 11, and a receiving portion 111 is formed in the middle of the frame to adapt to the island portion on the side of the second connector 20. The first signal terminal 12 and the first power terminal 13 are disposed in the frame portions of the first body 21 that are opposite each other in the width direction X.

[0068] Combination Figure 3 and Figure 4 As shown, the first signal terminal 12 includes a contact portion 121 and a solder foot 122 formed by sequential bending and extension. The contact portion 121 of the first signal terminal 12 is U-shaped and protrudes outward toward the second connector 20 side, for abutting and mating with the contact portion of the corresponding second signal terminal on the second connector 20 side. The solder foot 122 of the first signal terminal 12 is located on the surface of the first body 11 opposite to the second connector 20 in the insertion direction, for electrical connection with the circuit board pad on the corresponding side. Please also refer to... Figure 6 , Figure 7 and Figure 8 ,in, Figure 6 for Figure 4 A top view of the first connector shown. Figure 7 for Figure 6 CC section view in Figure 8 This is a schematic diagram illustrating the assembly relationship between a first connector and a first circuit board, provided as an embodiment of this application.

[0069] In this configuration, the solder pads 122 of the two rows of first signal terminals 12 extend towards each other. For example... Figure 6 and Figure 7 As shown, the solder feet 122 of the two rows of first signal terminals 12 overlap with the receiving portion 111 in the insertion direction, and in the width direction X, there is a first spacing L1 between the solder feet 122 of the two rows of first signal terminals 12; in other words, the soldering position formed by the solder feet 122 of the first signal terminals 12 is close to the middle of the first body 11. Figure 8 As shown, the first circuit board 30 includes two rows of first signal pads 31. For example, but not limited to, the first circuit board 30 can be a flexible printed circuit (FPC). In the width direction X, there is a second spacing L2 between the two rows of first signal pads 31, where L2 ≤ L1. The first spacing L1 can be minimized based on welding process requirements. Thus, for welding the two rows of first terminals, only one welding area requirement corresponding to L1 needs to be reasonably controlled. Compared to the traditional method where the spacing between the solder protrusions of the two rows of terminals and the corresponding side peripheral shielding parts must meet welding process requirements, the width dimension of the first connector 10 in this embodiment is effectively reduced.

[0070] Similarly, the first power terminal 13 includes a contact portion 131 and a solder foot 132 formed by sequential bending and extension. The contact portion 131 of the first power terminal 13 is U-shaped and protrudes outward toward the second connector 20 side for abutting and fitting with the contact portion of the corresponding second power terminal on the second connector 20 side. The solder foot 132 of the first power terminal 13 is located on the surface of the first body 11 opposite to the second connector 20 in the insertion direction for electrical connection with the circuit board pad on the corresponding side.

[0071] In this configuration, the solder feet 132 of the two rows of first power terminals 13 extend towards each other. For example... Figure 6 and Figure 7 As shown, in the projection plane of the insertion direction, the projection of the solder feet 132 of the first power terminal 13 does not exceed the projection of the frame of the first body 11. In the width direction X, the spacing between the solder feet 122 of the first signal terminal 12 is consistent with the spacing between the solder feet 132 of the first power terminal 13, that is, both are the first spacing L1 shown in the figure. Figure 8 As shown, the soldering positions formed by the solder feet 132 of the two rows of first power terminals 13 are close to the center of the first body 11; correspondingly, the first circuit board 30 includes first power pads 32, which are arranged in rows at intervals along the length direction Y, and the first power pads 32 are located on both sides of a plurality of first signal pads 31. Similar to the soldering process requirements of the first signal terminals 12, the space occupied by the soldering area of ​​the first power terminals 13 can be limited to the maximum extent while avoiding the influence of solder run.

[0072] Of course, in other possible implementations, the spacing between the solder pads of the two rows of first terminals can also be different in the width direction X. For example, the spacing between the solder pads 132 of the first power terminal 13 can be greater than the spacing between the solder pads 122 of the first signal terminal 12 (not shown in the figure), and vice versa. The specific spacing can be determined as needed, and this application embodiment does not limit it.

[0073] In addition, to improve the assembly processability of the first terminal and the first body, the solder feet of the two rows of first terminals can be staggered in the length direction Y. For example, as shown... Figure 6 As shown, the two rows of first signal terminals 12 are staggered by the dimensions indicated by mark T, which facilitates the arrangement during injection molding and reduces process implementation costs. In other possible implementations, the contact portions of the first signal terminals 12 and the second signal terminals 13 can be aligned along their length, with only the solder feet of the first signal terminals 12 and the second signal terminals 13 staggered. Comparatively, staggering the entire body of the two rows of first terminals results in relatively lower design and process implementation costs.

[0074] In this embodiment, the first shield 14 is located on the outer periphery of the first body 11 and is used to elastically mate with the pressing portion 242 of the second shield on the second connector 20 side in the insertion direction to form a reliable grounding shield link.

[0075] As shown in Figure 2 and Figure 3 The first shielding component 14 includes a spring-loaded portion 141 and a first soldering portion 142. The first soldering portion 142 is a circumferentially closed rectangular frame to fit the rectangular outline of the first body 11. It is understood that the first soldering portion 142 can be other types of annular closed structures, as long as a reliable shielding link can be established. Multiple spring-loaded portions 141 are provided and spaced apart on the first soldering portion 142. In the insertion direction, the surfaces of the first soldering portion 142 and the solder pads (solder pads 122 and 132) of each first terminal, away from the second connector 20, can be approximately flush to adapt for soldering to the first grounding pad 33 on the side of the first circuit board 30.

[0076] Each spring piece 141 is connected to the first welding part 142 and protrudes from the first welding part 142 toward the second connector 20 so that it is pressed and deformed by the second shield 24 of the second connector 20 in the insertion direction, and the electrical connection between the first shield 14 and the second shield 24 is achieved through elastic mating.

[0077] In a specific implementation, both the spring piece 141 and the first welding part 142 are made of metal to achieve electrical connection between the shielding components on both sides. In a specific implementation, the first shielding component 14 can be integrally formed by a stamping process, for example, but not limited to, stamping from a thin stainless steel sheet. Figure 4 and Figure 6 As shown, the first welding portion 142 is respectively arranged on the two opposite side frames of the first welding portion 142 in the width direction X. Each side frame is provided with five spring clip portions 141, and each spring clip portion 141 extends along the circumference of the first welding portion 142 to make full use of the rectangular frame structure to arrange the spring clip portions 141. In this way, the space occupied by the shielded grounding link in the first direction can be reduced simultaneously.

[0078] Of course, in other possible implementations, the spring piece 141 and the first welding part 142 can also be processed independently and then assembled and welded together, as long as the functional requirement of elastic interlocking in the insertion direction can be met. This application does not limit the embodiments.

[0079] For example, a first grounding pad 33 is arranged on the first circuit board 30. Figure 8 The first grounding pad 33 shown includes multiple pads, which are spaced apart from the rectangular frame of the first welding part 142. That is, the first grounding pads 33 are arranged discontinuously relative to the rectangular frame of the first welding part 142. This allows for reasonable control of welding stress and facilitates the routing layout of the first circuit board 30, providing good adaptability.

[0080] Of course, the structure of the first grounding pad 33 is not limited to the shape shown in the figure, and can be determined according to the overall product design requirements. This application does not limit the specific form.

[0081] In addition, in order to improve the welding accuracy between the first welding part 142 and the first circuit board 30, in the specific implementation, combined with Figure 8 As shown, the first soldering portion 142 includes a plurality of protrusions 1421 protruding toward the first circuit board 30, forming solder feet of the first shield 14. In other words, solder feet adapted to the first grounding pad 33 are formed by the protrusions 1421 protruding toward the side opposite to the second connector. Here, the outer surfaces of each protrusion 1421 are flush to improve the overall soldering accuracy and ensure the soldering reliability of each solder foot.

[0082] To further increase the end strength of the first connector, in a specific implementation, the first connector 10 may also include a first protective fitting, for example... Figure 3 As shown, two first protective fittings 15 are provided, and the two first protective fittings 15 are respectively provided at both ends of the first body 11 in the length direction Y. Figure 5 As shown, the first protective fitting 15 is mounted on the short side of the rectangular first body 11 and the local long side adjacent to both ends of the short side body.

[0083] The first protective fitting 15 includes an outer covering 151 and an inner guide 152. The outer covering 151 covers the outer surface of the first body 11 to prevent damage during assembly with the second shielding component on the second connector 20 side. The inner guide 152 bends inward from the outer covering 151 and covers the short side of the first body 11 to prevent damage during assembly with the island portion on the second connector 20 side. Here, the edge of the outer covering 151 away from the second connector side has a fixing solder pad 153. Correspondingly, a fixing pad 34 is provided on the first circuit board 30. The fixing solder pad 153 and the fixing pad 34 can be soldered and fixed to improve the reliability of the first connector 10 on the board.

[0084] In a specific implementation, the first protective fitting 15 can be made of stainless steel with a thickness of 0.06mm to ensure the strength of the device. For example, but not limited to, it can be manufactured by a drawing process, and the first protective fitting 15 and each first terminal can be integrally injection molded with the first body 11.

[0085] In this embodiment, the first shielding component 14 can be made of stainless steel with a thickness of 0.03mm-0.04mm by stamping. That is to say, the first shielding component 14 and the first body 11 are designed separately. The material thickness of the first shielding component 14 is thinner than that of the first protective fitting 15, so as to reasonably control the positive force formed in the insertion direction and achieve low yield.

[0086] Based on the connector assembly described in Figure 1, with the first shield 14 made of stainless steel with a thickness of 0.04 mm, a simulation test of the positive force of the spring part 141 was conducted. The test results regarding the positive force and the displacement of the extended end of the spring part 141 are as follows: Figure 9 As shown. Figure 9 The diagram shows the outgoing and returning curves during the simulation test. The positive force applied to the extended end of the spring piece 141 is shown on the vertical axis, and the displacement of the extended end of the spring piece 141 is shown on the horizontal axis.

[0087] like Figure 9 As shown, when the positive force is 0.12N, the forward displacement of the extended end of the spring piece 141 is 0.057mm, and the return displacement is 0.054mm. Thus, the positive force required to satisfy the reliability of the flexible electrical connection displacement is much smaller than the pull-out force of a typical BTB structure, ensuring a smooth insertion and removal process.

[0088] Here, for the plurality of first shielding members 14 arranged circumferentially extending along the first weld portion 142, such as Figure 6As shown, the distance M between the extended ends of two adjacent spring parts 141 can be 1.2mm-1.5mm. Overall, while achieving a good assembly feel, it can also ensure good isolation. According to the isolation simulation test, the fully shielded link constructed based on the connector assembly provided in this application has an isolation simulation result of -74dB, which shows good electromagnetic shielding effect and can effectively reduce the impact of electromagnetic interference.

[0089] Furthermore, based on the separate design architecture of the first shielding component 14 and the first body 11, for different scenarios with the same interconnection function, the first shielding component with different structural dimensions can be configured for the same first body 11 to adapt to board-side routing limitations. Overall, this can effectively reduce the assembly and implementation cost of devices with the same interconnection function. Of course, for the first shielding component 14 and the first protective fitting 15 made of metal materials, in other specific implementations, the two can also be integrally formed using a drawing process. The specifics can be determined according to the overall product design requirements, and this application embodiment does not limit this.

[0090] For the first shielding member, in addition to the aforementioned elastic electrical connection formed by the spring portion 141 based on the metal first shielding member 14, the spring portion 141, as an elastic electrical connection member, can also adopt other structural forms. Please see Figure 10 The figure is a schematic diagram of another first shielding component provided in an embodiment of this application.

[0091] like Figure 10 As shown, the first shielding member 14a includes a first welding portion 142a and conductive foam 141a. The first welding portion 142a is also a circumferentially closed metal rectangular frame to adapt to the rectangular outline of the first body 11. The conductive foam 141a covers the surface of the first welding portion 142a facing the second connector. Based on the fact that the conductive foam 141a can be deformed by the second shielding member 24 of the second connector 20 in the insertion direction, a reliable electrical connection between the first shielding member 14a and the second shielding member 24 is achieved through elastic mating.

[0092] In a specific implementation, the conductive foam 141a, as a flexible conductive material, can be continuously arranged along the first welded portion 142a to improve the overall shielding capability. Of course, in other implementations, the conductive foam 141a can also be arranged discontinuously, still forming a reliable grounding shielding link. This application does not limit the specific implementation.

[0093] Alternatively, the conductive foam 141a can be replaced with other flexible conductive materials such as conductive gel (not shown in the figure), which can also adaptively form an elastic electrical connection in the insertion direction. That is, by pressing the conductive gel covering the first welding part 142a against the second shield 24 of the second connector 20, an electrical connection is achieved between the first shield 14a and the second shield 24. In a specific implementation, an insertion limiting structure (not shown in the figure) can also be configured between the first connector 10 and the second connector 20 to obtain an insertion stroke that can meet the requirements for achieving an electrical connection based on conductive gel.

[0094] In other possible implementations, the first shielding element can also be formed using conductive foam, compared to Figure 10 The implementation scheme shown can further reduce product realization costs.

[0095] In this embodiment, the second connector 20 includes a second body 21, a second signal terminal 22, a second power terminal 23, and a second shielding member 24. Please refer to [the documentation / reference]. Figure 11 and Figure 12 ,in, Figure 11 Figure 1 shows a schematic diagram of the overall structure of the second connector. Figure 12 for Figure 11 A schematic diagram showing the first connector from another perspective.

[0096] like Figure 11 As shown, the second body 21 serves as the terminal fixing base structure for the second connector 20 and is made of insulating material. The second signal terminal 22 and the second power terminal 23 are first terminals fixed to the second body 21. Exemplarily, the second terminals can be injection molded into an integral structure with the second body 21. Please refer to [further details omitted]. Figure 13 and Figure 14 ,in, Figure 13 for Figure 11 An exploded view of the assembly of the second connector shown in the figure. Figure 14 for Figure 11 A partial exploded view of the first connector.

[0097] Along the width direction X (first direction) of the second connector 20, two rows of second terminals are spaced apart. Along the length direction Y (second direction) of the second connector 20, rows of second terminals (second signal terminals 22 and second power terminals 23) are arranged sequentially at intervals, with the second power terminals 23 located on both sides of the plurality of first signal terminals 22.

[0098] In a specific implementation, the second signal terminal 22 and the second power terminal 23 are respectively provided in a one-to-one correspondence with the first terminals (first signal terminal and first power terminal) on the side of the first connector 10. The number of the second signal terminal 22 and the second power terminal 23 can be determined according to the overall design requirements of the connector assembly, and is not limited in this embodiment.

[0099] In other specific implementations, the second power terminal 23 and the first power terminal can be selectively configured. In other words, for connector assemblies that do not require power supply, only interoperable signal terminals can be configured; this application embodiment does not impose any limitations.

[0100] In this embodiment, the second body 21 is generally rectangular and includes an outer frame body 211 and an island portion 212. The island portion 212 is located inside the outer frame body 211, and an annular recess 213 is formed between the two for insertion and fitting with the first connector 10. The island portion 212 can also be inserted and fitted with the receiving portion 111 on the side of the first connector 10. Two rows of second terminals are arranged in the long side recesses of the annular recess 213, and the contact portion of each second terminal is exposed on the opposing wall surfaces of the outer frame body 211 and the island portion 212 to abut and mate with the first terminal on the side of the first connector 10.

[0101] The second signal terminal 22 includes a contact portion 221 formed by sequential bending and extension, and a solder foot 222, which can be seen together. Figure 15 and Figure 16 ,in, Figure 15 for Figure 12 Top view of the second connector shown. Figure 16 for Figure 15 DD section view in the image.

[0102] The contact portion 221 of the second signal terminal 22 is U-shaped and recessed towards the first connector 10, for abutting and mating with the contact portion of the corresponding first signal terminal on the first connector 10 side; the solder feet 222 of the second signal terminal 22 are located on the surface of the second body 21 opposite to the first connector 10 in the insertion direction, for electrical connection with the circuit board pads on the corresponding side. Please refer to [further details omitted]. Figure 17 The figure is a schematic diagram of the assembly relationship between a second connector and a second circuit board provided in an embodiment of this application.

[0103] In this configuration, the solder pads 222 of the two rows of second signal terminals 22 extend towards each other. For example... Figure 15 and Figure 16As shown, in the projection plane of the insertion direction, the projection of the solder feet 222 of the second signal terminal 22 does not exceed the projection of the frame of the second body 21. In the width direction X, there is a first spacing L1 between the solder feet 222 of the two rows of second signal terminals 22; in other words, the soldering position formed by the solder feet 222 of the second signal terminal 22 tends to be located close to the middle of the second body 21. Figure 17 As shown, the second circuit board 40 includes two rows of second signal pads 41. For example, but not limited to, the second circuit board 40 can be a circuit board. The two rows of second signal pads 41 are respectively disposed corresponding to two rows of second signal terminals 22. In the width direction X, there is a second distance L2 between the two rows of second signal pads 41, where L2 ≤ L1. The first distance L1 can be minimized based on the welding process requirements. In this way, for the welding of the two rows of second terminals, the welding area requirements of L1 can be reasonably controlled. Compared with the traditional two rows of terminals where the distance between the solder feet and the corresponding side outer peripheral shielding needs to meet the welding process requirements, the width dimension of the second connector 20 in this embodiment is effectively reduced.

[0104] Similarly, the second power terminal 23 includes a contact portion 231 and a solder foot 232 formed by sequential bending and extension. The contact portion 231 of the second power terminal 23 is U-shaped and recessed away from the first connector 10, for abutting and fitting with the contact portion of the corresponding first power terminal on the side of the first connector 10. The solder foot 232 of the second power terminal 23 is located on the surface of the second body 21 opposite to the first connector 10 in the insertion direction, so as to electrically connect with the circuit board pad on the corresponding side.

[0105] In this configuration, the solder feet 232 of the two rows of second power terminals 23 extend towards each other. For example... Figure 15 As shown, in the projection plane of the insertion direction, the projection of the solder feet 232 of the second power terminal 23 does not exceed the projection of the frame of the second body 21. In the width direction X, the spacing between the solder feet 222 of the second signal terminal 22 is consistent with the spacing between the solder feet 232 of the second power terminal 23, that is, both are the first spacing L1 shown in the figure; in other words, the soldering position formed by the solder feet 232 of the second power terminal 23 tends to be set close to the middle of the second body 21. Figure 17 As shown, the second circuit board 40 includes a second power pad 42. Along the length Y direction, the pads are arranged in rows at intervals, and the second power pad 42 is located on both sides of a plurality of second signal pads 41. Similar to the soldering process requirements of the second signal terminal 22, the space occupied by the required soldering area for the second power terminal 23 can be minimized while avoiding the effects of solder run-through.

[0106] Of course, in other possible implementations, the spacing between the solder pads of the two rows of second terminals in the width direction X can also be different. For example, the spacing between the solder pads 232 of the second power terminal 23 can be greater than the spacing between the solder pads 222 of the second signal terminal 22 (not shown in the figure), and vice versa. The specific spacing can be determined as needed, and this application embodiment does not limit it.

[0107] Furthermore, the second body 21 has a process opening for cutting and forming the solder feet of the second terminal. Combined with... Figure 10 , Figure 14 and Figure 15 As shown, the island portion 212 of the second body 21 has multiple process openings 2121, which penetrate the second body 21 in the insertion direction. Each process opening 2121 corresponds to a second terminal (second signal terminal 22 and second power terminal 23). In the projection plane in the insertion direction (see...), Figure 15 The projections of the solder feet (solder feet 222 and 232) of the second terminal are located within the projection of the corresponding process opening 2121. In this way, after the terminal injection molding is completed, it can be cut through the corresponding process opening 2121 to form solder foot ends that meet the spacing requirements.

[0108] It is understood that the size of the process opening 2121 corresponds to the size of the corresponding solder pad. For example, as shown in the figure, the process opening 2121 corresponding to the solder pad 232 of the second power terminal 23 is larger than the process opening 2121 corresponding to the solder pad 222 of the second signal terminal 22. The specific size can be determined according to the overall product design requirements, and this application embodiment does not limit it.

[0109] In addition, to improve the assembly processability of the second terminal and the second body, the two rows of second terminals can be staggered in the length direction Y, for example, as follows: Figure 15 As shown, the two rows of second signal terminals 22 are arranged in a staggered manner with the dimensions indicated by the mark T. It should be understood that, in the length direction Y, the second signal terminals 22 of the second connector 20 are arranged in a one-to-one correspondence with the first signal terminals 12 of the first connector 10.

[0110] It should be noted that, in the width direction, the solder joint spacing of the first terminal can be the same as that of the corresponding second terminal, i.e., both are the first spacing L1. In other possible implementations, based on different upper board soldering process conditions, the solder joint spacing of the first terminal can also be different from that of the corresponding second terminal. This application does not limit the implementation.

[0111] In this embodiment, the second shield 24 is fitted around the outer periphery of the outer frame body 211 and is used to elastically interlock with the first shield on the first connector 10 side in the insertion direction to form a reliable grounding shield link.

[0112] As shown in Figure 2 and Figure 3 The second shielding member 24 includes an outer shell 241, a pressing part 242, and a second welding part 243. The outer shell 241 is a rectangular cylinder adapted to fit the outer frame body 211. The outer shell 241 includes a first end 241a and a second end 241b disposed opposite to each other. The pressing part 242 is connected to the first end 241a of the outer shell 241 to press and engage with the spring piece part 141 of the first shielding member 14. The second welding part 243 is connected to the second end 241b of the outer shell 241 to be adapted for welding to the second grounding pad 43 on the side of the second circuit board 40.

[0113] For the second grounding pad 43 arranged on the second circuit board 40, exemplarily, Figure 17 The second grounding pad 43 shown includes two U-shaped pad structures and four strip-shaped pad structures. The two U-shaped second grounding pads 43 are positioned corresponding to the short sides of the rectangular second welding portion 243, while the four strip-shaped second grounding pads 43 are positioned corresponding to the long sides of the rectangular second welding portion 243. Adjacent second grounding pads 43 are spaced apart; that is, relative to the rectangular second welding portion 243, the second grounding pads 43 are arranged discontinuously to facilitate the routing layout of the second circuit board 40. This provides good adaptability.

[0114] Of course, the structure of the second grounding pad 43 is not limited to the shape shown in the figure, and can be determined according to the overall product design requirements. This application does not limit the specific form.

[0115] In a specific implementation, the pressing part 242 bends inward from the first end of the outer shell 241, combined with... Figure 13 and Figure 16 As shown, the pressing portion 242 can cover the end face of the outer frame body 211 facing the first connector 10. Thus, the structure for building the shielded link on the second shield 24 side is integrated into the top of the outer frame body 211, without occupying the width dimension space of the second connector 20. Overall, this results in better device integration, providing technical assurance for further reducing the board area occupied by the second connector 20.

[0116] In addition, the second shielding member 24 may also include two inner covering portions 244, which are provided at both ends of the outer frame body 211 in the length direction Y. The inner covering portions 244 are bent downward from the inner edge of the pressing portion 242 and can cover the inner wall of the outer frame body 211 to avoid damage during assembly with the first connector 10. That is, by having the two inner covering portions 244 correspond one-to-one with the short sides of the outer frame body 211, corresponding protective functions are provided.

[0117] Furthermore, to improve the assembly processability of the second shielding component 24, in a specific implementation, an assembly positioning pair is provided between the second shielding component 24 and the second body 21. Based on the assembly positioning pair, the two components can be relatively limited in the insertion direction. In this embodiment, the inner covering portion 244 of the second shielding component 24 is provided with a limiting groove 2441, the opening of the limiting groove 2441 facing the side opposite to the pressing portion 242, and a limiting block 2111 is correspondingly provided on the inner wall surface of the outer frame body 211. During assembly, when the second shielding component 24 is fastened to the outer frame body 211, the bottom of the limiting groove 2441 can abut against the limiting block 2111 of the outer frame body 211, thereby limiting the second shielding component 24 and the second body 21 in the insertion direction. In this way, the operability during the assembly process can be improved, the assembly processability is better, and the corresponding structure does not occupy the width dimension space of the second connector 20.

[0118] In other specific implementations, the corresponding limiting groove and limiting block can also be arranged in reverse. That is, the limiting block is arranged on the side of the second shield 24, and the limiting groove is arranged on the side of the second body 21 (not shown in the figure), which can also achieve the limiting of the second shield 24 and the second body 21 in the insertion direction. The specific arrangement can be determined according to the overall product design requirements, and this application embodiment does not limit it.

[0119] To further increase the end strength of the second connector, in a specific implementation, the second connector 20 may also include a second protective fitting, for example... Figure 10 and Figure 13 As shown, two second protective fittings 25 are provided, and the two second protective fittings 25 are respectively provided at both ends of the island portion 212 in the length direction Y. Figure 13 As shown, the second protective fitting 25 is mounted on the short side body of the rectangular island 212 and the partial long side body adjacent to both ends of the short side body to avoid damage during assembly with the first connector 10.

[0120] In a specific implementation, the second protective fitting 25 can be made of stainless steel, for example, but not limited to, by drawing process or gold-plating stamping process, and the second protective fitting 25 and each second terminal can be integrally injection molded with the second body 21.

[0121] In addition to the aforementioned connector assembly, this application also provides an electronic device, which includes a circuit board and a device module. The device module is connected to the circuit board via the aforementioned connector assembly. Examples include, but are not limited to, mobile phones, tablets, and laptops. The device module connected to the circuit board via the connector assembly can be a camera module or a battery module, etc. Based on this connector assembly, while meeting good shielding requirements, the assembly space occupied by the connector can be reasonably controlled, meeting the design requirements of product miniaturization trends.

[0122] In practical applications, the aforementioned technological advantages are even more pronounced in scenarios involving the assembly of camera modules.

[0123] It should be understood that the other functions of the electronic device are not the core inventive points of this application, and therefore will not be elaborated upon here.

[0124] Furthermore, the ordinal numbers "first" and "second," etc., used herein are only for describing the composition or structure of the same function in the technical solution. It is understood that the use of the aforementioned ordinal numbers does not constitute a limitation on the understanding of the technical solution for which protection is sought in this application.

[0125] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
