Description

Technical Field

[0001] The present invention belongs to the technical field of electrical connectors, and particularly relates to a connector, a mating connector, and a floating connector assembly. Background Art

[0002] As an important component for data transmission, the use of board-to-board connectors has increased exponentially with the development of digitalization in various industries. Especially in fields such as intelligent driving and robotics, there is a great dependence on high-frequency and high-speed data transmission, and a large number of board-to-board connectors are even more indispensable.

[0003] However, with the continuous deepening of the application fields, the board-to-board connectors installed in electronic devices have also encountered many problems. Among them, as the distance between circuit boards increases, during the movement state, relative displacement may occur between the boards due to sudden changes in the movement state, causing deformation at both ends of the connector insertion. The larger the board spacing, the greater the deformation amount, which easily leads to a decrease in the transmission stability of the connector or the possibility of connector damage. In addition, due to the increase in board spacing, there is also a situation where the installation error of the connector increases. During static installation, it is easy to cause the possibility of local "virtual connection" between terminals.

[0004] In existing solutions, when the board spacing is large, the relevant connectors are often replaced with two wire-to-board connectors and a high-speed data line. However, this solution sacrifices transmission efficiency and limits the data transmission capacity between boards. In current floating board-to-board connectors, the contact distance of the contact terminals is increased to ensure the stability of terminal contact. However, as the board spacing increases, the method of increasing the contact distance obviously far from meets the actual situation. At the same time, during high-frequency and high-speed data transmission, problems such as introducing interference variables, data transmission loss, and terminal coating wear will also occur due to the sliding friction between terminals. Summary of the Invention

[0005] To solve the deficiencies of the above-mentioned prior art, the present invention provides a connector, a mating connector, and a floating connector assembly. The main body is set as a smooth linear structure, and the first terminal is injection-molded in the first housing; then the support arm is elastically connected to the base, and the second terminal is elastically arranged between the first mating housing and the second mating housing. Even when there is a large deviation in the static connection position, or when there is a large offset between the circuit boards during operation, the connector and the mating connector can still perform stable and high-speed data transmission.

[0006] The technical effects to be achieved by the present invention are realized through the following technical aspects:

[0013] In some implementation manners, the main body portion extends along the height direction and is provided with a fixing portion that is thickened in the transverse direction; the end wall is provided with a hollowed-out groove, and the fixing portion is arranged corresponding to the hollowed-out groove.

[0014] In some implementation manners, the fixing portion includes a first fixing block and a second fixing block. In the transverse direction, the width of the first fixing block is the same as the width of the second fixing block;

[0015] In the longitudinal direction, the thickness of the first fixing block is the same as the thickness of the second fixing block;

[0016] In the height direction, the height of the first fixing block is the same as or different from the height of the second fixing block, and the first fixing block and the second fixing block are alternately arranged on the main body portion.

[0017] In some implementation manners, neither the first fixing block nor the second fixing block extends a convex block structure in the transverse direction.

[0018] In some implementation manners, the first housing includes two monomers assembled together; in each monomer, there is a complete end wall; the main body portion is injection molded in the end wall, and further the first terminal and the monomer form an integral structure.

[0019] In a second aspect, the present invention provides a mating connector that is mated and plugged with any one of the above-mentioned connectors. The mating connector includes:

[0020] The first mating housing includes a pair of mating side walls oppositely arranged in the transverse direction, a pair of mating end walls arranged in the longitudinal direction, and a pair of support arms; the mating side walls and the mating end walls jointly enclose to form a third chamber, and the support arms extend from the lower ends of the mating side walls in the transverse and height directions;

[0021] The second mating housing is provided with a base and a receiving groove arranged above the base, the first mating housing is mounted on the receiving groove, and the support arms are elastically connected to the base; and

[0022] The second terminal is an integrally formed elastic metal part, and the second terminals are respectively connected to the first mating housing and the second mating housing.

[0023] In some implementation manners, the second terminal includes a first bent part, a second bent part and a third bent part which are sequentially bent and connected;

[0024] The first bent part is partially located in the first mating housing and partially located in the second mating housing;

[0025] The second bent part is partially located in the second mating housing and partially located in the receiving groove and clamps the first mating housing;

[0026] The third bent part is embedded and connected to the second mating housing.

[0027] In some implementation manners, the first bent part is provided with a second contact part, the second contact part is first bent in a direction away from the third chamber, and then bent in a direction close to the third chamber to form, and the second contact part is connected to the first contact part.

[0028] In some embodiments, the mating connector further includes a U-shaped resilient member, the resilient member includes an integrally formed first elastic part and a second elastic part, the first elastic part is fixed to the bottom of the support arm, and the second elastic part abuts against the base.

[0029] In a third aspect, the present invention further provides a floating connector assembly, including the connector as described in any one of the above and the mating connector as described in any one of the above, the connector is matingly inserted into the mating connector, and the connector can drive the first mating housing to move downward in the height direction relative to the second mating housing.

[0030] In summary, the present invention has at least the following advantages:

[0031] 1. The connector provided by the present invention has a smooth linear structure for the main body, and the first terminal is injection-molded in the first housing in the mold, which improves the manufacturing feasibility; for high-frequency and high-speed inter-board data transmission, it has high stability while reducing signal transmission.

[0032] 2. For the connector provided by the present invention, the first terminal does not require a dedicated mold. During mass production, the raw material length can be selected according to needs to adapt to the requirements of different board spacings. On the premise of ensuring the firm connection between the first terminal and the first housing, the utilization rate of the first terminal production line is improved, and the processing difficulty and production cost of various length models of the connector are reduced.

[0033] 3. For the mating connector provided by the present invention, the independently provided first mating housing and the second mating housing are elastically connected to the base through a support arm, and the second terminal is elastically arranged between the first mating housing and the second mating housing. When there is a large deviation or offset between the first mating housing and the second mating housing in the height direction, the mating connector can still ensure the electrical connection effectiveness and stability of the overall structure within the design range.

[0034] 4. For the floating connector assembly provided by the present invention, after the connector is inserted into the mating connector, since the first mating housing and the second mating housing form a floating connection, even if there is a large error value in the static connection position between the connector and the mating connector, or relative displacement occurs between the circuit boards during the operation of the device, the connector can still maintain a relatively static connection state with the first mating housing, and the connector can drive the first mating housing to move downward relative to the second mating housing in the height direction; the connection positions of the first terminal and the second terminal remain basically unchanged, avoiding the situation of virtual connection or unstable transmission, and improving the safety and service life of data transmission.

[0064] For better understanding of the content of the drawings, necessary explanations are made in advance regarding the three-axis coordinates and directions of the drawings. Among them, the X-axis represents the transverse coordinate, the Y-axis represents the longitudinal coordinate, and the Z-axis represents the height direction coordinate.

[0065] Embodiment 1:

[0066] Please refer to Figures 1 - 2, this embodiment provides a connector 100, which includes a first housing 1, a second housing 2 and a first terminal 3. The first housing 1 is used to fix the first terminal 3, and specifically includes a pair of side walls 11 oppositely arranged in the transverse direction X and a pair of end walls 12 arranged in the longitudinal direction Y. The side walls 11 and the end walls 12 jointly surround to form a first chamber 13. The first chamber 13 is used to provide installation conditions when the connector 100 is electrically connected to a mating connector plugged thereinto. The second housing 2 is used to fix the first housing 1 and the first terminal 3, and forms a fixing structure with a circuit board at one end, providing the main bearing capacity of the connector 100. The second housing 2 is provided with a second chamber 21, and the first housing 1 is installed in the second chamber 21.

[0067] The first terminal 3 is disposed in the first housing 1 through an in-mold injection process. Figures 1 - 2 On this basis, referring to Figure 3 , the first terminal 3 includes a main body portion 31, a first contact portion 32 and a mounting portion 33 provided at both ends of the main body portion 31. The first contact portion 32 is disposed on the inner side surface of the first chamber 13. Through plugging in the first chamber 13, the connector 100 is electrically connected to its mating connector.

[0068] Continuing to refer to Figures 1 - 3 , the mounting portion 33 is bent from the lower end of the main body portion 31 in a direction away from the first chamber 13. An installation groove 121 is provided on the end wall 12 of the first housing 1, and the mounting portion 33 of the first terminal 3 is embedded in the installation groove 121. The mounting portion 33 is bent and embedded in the installation groove 121, so that while ensuring a firm connection with the first housing 1, the mounting portion 33 can be exposed outside the second housing 2, so as to be welded to the electrical contact of the circuit board at one end of the connector 100.

[0069] In this embodiment, the main body portion 31 is a smooth linear structure in the height direction Z. Preferably, the main body portion 31 is a smooth straight structure in the height direction Z. In some other embodiments, the main body portion 31 may also be a smooth curved structure. The specific linear type is selected according to design requirements, and the main body portion 31 with a straight structure has advantages in traditional high-frequency and high-speed data transmission, such as stable transmission, small probability of data loss and error.

[0070] At the same time, the smooth straight structure enables multiple first terminals 3 in the same row to be cut from flat raw materials during production and produced and formed together, greatly reducing the production process difficulty of the first terminals 3 and greatly improving the production efficiency. In addition, if it is necessary to produce the same type of connector 100 with different lengths, only the raw material length of the first terminal 3 and the injection mold of the first housing 1 need to be changed, improving the production feasibility; at the same time, the input cost and production cost of producing different lengths of the connector 100 in the later stage are reduced, and the production line change time of different lengths of the connector 100 is also reduced.

[0071] In some embodiments, as Figure 4 shown, the main body portion 31 extends along the height direction Z and has a constant width in the transverse direction X and a constant thickness in the longitudinal direction Y. That is, at any position perpendicular to the height direction Z, the planar cross-section of the main body portion 31 in the transverse direction X and the longitudinal direction Y is the same, which is a uniform structure. And through in-mold injection into the first housing 1, the periphery of the main body portion 31 of each first terminal 3 is wrapped by the material of the first housing 1. This ensures that the first terminals 3 do not interfere with each other during data transmission, and the data transmission process is stable and controllable. Due to the above settings, compared with the existing fixed structure between the terminal and the housing, the above-mentioned first terminal 3 can be set according to the minimum distance between the terminals, thereby improving the terminal density of the connector and the data transmission ability. It meets the higher frequency and high-speed data transmission requirements of the board-to-board connector.

[0072] In the existing floating connector male terminal products, the assembly terminals and the housing are assembled. The assembly method designs the terminal as a fixed structure with protrusions, but this will cause a large loss of signal transmission. In this embodiment, by using the first terminal with a uniform structure for the main body portion, on the one hand, the manufacturing feasibility is improved, and on the other hand, the signal transmission loss is reduced.

[0073] In some embodiments, in order to meet the requirements of detection, weight reduction, etc., the main body portion 31 extends along the height direction Z and is provided with a fixing portion 310 that is thickened in the transverse direction X. Correspondingly, a hollowed-out groove 122 is provided on the end wall 12, and the fixing portion 310 is arranged corresponding to the hollowed-out groove 122.

[0074] As Figures 1 - 3 shown, on the first housing, the hollowed-out grooves 122 are arranged at regular intervals, which can be used to detect whether each interval of the first terminal 3 in the height direction Z meets the relevant electrical requirements during the production process. When the first terminal 3 and the first housing 1 are in-mold injection molded, setting the hollowed-out grooves 122 also facilitates the better demolding of the first housing 1 and reduces the weight of the first housing 1. At the same time, considering that the electrical properties of metal terminals are different in different environmental media, to ensure that problems such as data transmission distortion occur during the process of crossing different environmental media, the main body portion 31 is provided with a thickened fixing portion 310 corresponding to the position of the hollowed-out groove 122 to solve the above problems.

[0075] Further, the fixing part 310 includes a first fixing block 311 and a second fixing block 312. In the transverse direction X, the width of the first fixing block 311 is the same as that of the second fixing block 312. In the longitudinal direction Y, the thickness of the first fixing block 311 is the same as that of the second fixing block 312. In the height direction Z, the height of the first fixing block 311 may be the same as or different from that of the second fixing block 312, and the first fixing block 311 and the second fixing block 312 are alternately arranged on the main body part 31. The arrangements of the first fixing block 311 and the second fixing block 312 face different situations of the hollow slots 122. In this actual example, the height of the first fixing block 311 is different from that of the second fixing block 312, and the height of the first fixing block 311 is greater than that of the second fixing block 312. Please refer to Figures 1 - 3 on the basis of Figure 5 , when the hollow slot 122 penetrates through the first housing 1, setting the first fixing block 311 at the hollow slot 122 will have a better data transmission effect. When the hollow slot 122 is only arranged on one side of the first chamber 13, the second fixing block 312 with a smaller height can meet the corresponding effect.

[0076] The alternate arrangement of the first fixing block 311 and the second fixing block 312 helps to realize the standardization of the main body part 31 and adapt to the requirements of connectors of the same series with different lengths.

[0077] Furthermore, neither the first fixing block 311 nor the second fixing block 312 extends a bump structure in the transverse direction X. In the existing connectors, the terminals often have bump structures on the side walls, such as serrated or conical bumps, so that after the terminals are installed in the housing, the terminals can be more accurately snapped in place. In the present invention, due to the use of the in-mold injection process, the first terminal 3 and the first housing 1 can be firmly connected together without setting bump structures. Moreover, after no bump structures are set, the center distance between the terminals can be set closer, improving the terminal density of the connector 100, thereby increasing the overall data transmission capacity of the connector 100. In addition, after there are no bump structures, the generation of waste during the production of the first terminal 3 is reduced, and the production cost of the connector 100 is lowered.

[0078] In some embodiments, the first housing 1 includes two monomers 14 assembled together. In each monomer 14, there is a complete end wall 12. The main body part 31 is injection-molded in the end wall 12, and then the first terminal 3 and the monomer 14 form an integral structure. Refer to Figures 1 - 5 , the two monomers 14 are symmetrically arranged and form the first chamber 13 at one end by surrounding, and two groups of first terminals 3 are symmetrically arranged in the two end walls 12. Since the two monomers 14 have the same shape or are symmetrical, the molding difficulty of the first housing 1 and the first terminal 3 during production is reduced. At the same time, the terminal density of the connector 100 is doubled.

[0079] In this embodiment, as Figure 6 shown, in the horizontal X direction, the width of the fixing portion 310 is W1, and the distance between two adjacent first terminals 3 is W2, and they have the relationship: W1 > W2. Since the first terminal 3 and the first housing 1 are fixed by in-mold injection molding, the molding material of the first housing 1 will be filled between adjacent first terminals 3. Under the interval of the molding material of the first housing 1, the interference of electrical signals between adjacent first terminals 3 will be greatly reduced. Therefore, the distance between two adjacent first terminals 3 can be set to be less than the width of the fixing portion 310 to improve the data transmission capacity of the connector 100.

[0080] In some embodiments, the first housing 1 can be better installed in the second chamber 21 through a snap structure. Structures such as inserts 22 and jacks 23 can also be provided on both sides of the end where the second housing 2 is connected to the circuit board to achieve the quick connection between the connector 100 and the circuit board.

[0081] In summary, for the connector provided in this embodiment, by setting the main body portion as a smooth linear structure and in-mold injecting the first terminal into the first housing, the manufacturing feasibility is improved; for high-frequency and high-speed inter-board data transmission, the stability of data transmission is more stable than the existing technical solutions.

[0082] Secondly, the first terminal does not require a dedicated mold. During mass production, the raw material length can be selected according to needs to adapt to the requirements of different board spacings. On the premise of ensuring the firm connection between the first terminal and the first housing, the utilization rate of the first terminal production line is improved, and the processing difficulty and production cost of various length models of the connector are reduced.

[0083] Embodiment 2:

[0084] Please refer to Figures 7 - 8 , this embodiment provides a mating connector 200, one end of which is mated and inserted with the connector 100 in Embodiment 1, and the other end is electrically connected to a second circuit board, so as to achieve high-frequency and high-speed data transmission between boards. The mating connector 200 of this embodiment includes a first mating housing 4, a second mating housing 5, and a second terminal 6.

[0085] The first mating housing 4 includes a pair of mating side walls 41 oppositely arranged in the transverse direction X, a pair of mating end walls 42 arranged in the longitudinal direction Y, and a pair of support arms 43. The mating side walls 41 and the mating end walls 42 jointly enclose to form a third chamber 44, and the support arms 43 are formed by extending from the lower ends of the mating side walls 41 in the transverse direction X and the height direction Z. The second mating housing 5 is provided with a base 51 and a receiving groove 52 arranged above the base 51. The first mating housing 4 is mounted on the receiving groove 52, and the support arms 43 are elastically connected to the base 51. The second terminal 6 is an integrally formed elastic metal part, and the second terminal 6 is respectively connected to the first mating housing 4 and the second mating housing 5.

[0086] By elastically connecting the support arms 43 with the base 51 and providing the elastic second terminal 6, an elastic floating structure is formed between the first mating housing 4 and the second mating housing 5. When the first mating housing 4 bears a certain load in the height direction Z and deforms, the connection relationship between the first mating housing 4 and the second mating housing 5 can also be stably maintained, and the second terminal 6 will follow the deformation of the first mating housing 4 to generate displacement, realizing stable electrical connection.

[0087] During the implementation process, in order to ensure that the support arms 43 can be better restricted on the base 51, a locking part 53 is also inserted in the height direction Z of the receiving groove 52. The locking part 53 and the receiving groove 52 surround the support arms 43, restricting the support arms 43 in the receiving groove 52 to prevent the support arms 43 from popping out of the receiving groove 52. Of course, in other embodiments, the end of the locking part 53 can also be provided with an insertion structure to fixedly connect the mating connector 200 with the circuit board, thereby simplifying the mating connector 200.

[0088] In addition, during the static installation process, there will also be a certain deviation between the connector 100 and the mating connector 200, especially in the height direction Z. When the installation error between the two circuit boards is relatively large, the first mating housing 4 can also absorb the installation error between the two to ensure the reliability and stability of the connection.

[0089] On the basis of Figures 7 - 8 , refer to Figure 9 . Specifically, the second terminal 6 includes a first bent part 61, a second bent part 62, and a third bent part 63 that are sequentially bent and connected. The first bent part 61 is partially located in the first mating housing 4 and partially located in the second mating housing 5. The second bent part 62 is partially located in the second mating housing 5 and partially located in the receiving groove 52 and clamps the first mating housing 4. The third bent part 63 is embedded and connected to the second mating housing 5. The second terminal 6 realizes the connection of the second terminal 6 with the first mating housing 4 and the second mating housing 5 respectively through three bent parts formed by two bends. Just as Figure 8As shown, two relatively symmetrically arranged second terminals 6 are provided. The first bending members 61 of both of them press against and abut against the first mating housing 4 and extend into the third chamber 44 to ensure that when the first mating housing 4 and the second mating housing 5 are displaced, the first bending member 61 can move along with the first mating housing 4. The third bending member 63 abuts against and is fixed to the inner side of the second mating housing 5, thereby ensuring the accurate welding between the second terminal 6 and the circuit board. The second bending member 62 is movably arranged between the first bending member 61 and the second bending member 62. When deformation occurs, the bending positions at both ends of the second bending member 62 absorb energy and deform, driving the displacement of the second bending member 62, so that the second terminal 6 closely follows the movement of the first mating housing 5, ensuring stable electrical connection with the first terminal 3.

[0090] In this embodiment, the bending parts between the first bending member 61 and the second bending member 62, and between the second bending member 62 and the third bending member 63 are all large-radius rounded corners. The large-radius rounded corners have a better energy absorption effect compared to the small-radius rounded corners, which is used to disperse the stress during the floating of the terminal, enabling the second terminal 6 to have a greater deformation ability, thereby meeting the large displacement generated by the first mating housing 4. The bending amplitudes of adjacent bending members are all obtuse angles, which further simplifies the elastic structure of the second terminal 6. This enables the production cost of the second terminal 6 to be lower while ensuring that the amount of deformation is large enough.

[0091] In a further embodiment, the first bending member 61 is provided with a second contact portion 611. The second contact portion 611 first bends away from the third chamber 44 and then bends towards the third chamber 44 to form. The second contact portion 611 is connected to the first contact portion 32. The setting of the second contact portion 611 enables, during the connection process of the connector 100 and the mating connector 200, even if there is a certain inclination angle or local deformation between the first contact portion 32 and the second contact portion 611, the second contact portion 611 can stably abut against the surface of the first contact portion 32, ensuring the reliability of the electrical connection.

[0092] As Figure 10 shown, in order to further reduce the production difficulty and reduce the plastic wear generated during floating, the mating connector 200 further includes a U-shaped resilient member 7. The resilient member 7 includes an integrally formed first elastic portion 71 and a second elastic portion 72. The first elastic portion 71 is fixed to the bottom of the support arm 43, and the second elastic portion 72 abuts against the base 51. In this embodiment, during production and assembly, a slot 431 for fixing the resilient member 7 is provided at the bottom of the support arm 43, and the first elastic portion 71 is inserted into the slot 431 to complete the fixation. Generally, a pit 511 for abutting and restricting the second elastic portion 72 is provided on the base 51, and a convex portion 721 matching the pit 511 is provided on the second elastic portion 72. During installation, the convex portion 721 abuts against and sinks into the pit 511, thereby realizing the abutment and limiting of the second elastic portion 72 and the base 51.

[0093] Of course, in some other embodiments, the first elastic part 72 can also be fixed to the base 51, and the first elastic part 71 is in contact with the support arm 43, which can also achieve the floating connection effect between the first mating housing 4 and the second mating housing 5. The rebounding member 7 is generally an elastic metal sheet bent to form an elastic U-shaped structure, and this structure has a better energy absorption effect.

[0094] It should be noted that when the connector 100 of Embodiment 1 is adopted, the width of the fixing part 310 is greater than the spacing width between adjacent first terminals 3. Correspondingly, the second terminals 6 in the mating connector 200 also have corresponding dimensional relationships, that is, the width of the second terminals 6 is greater than the spacing width between adjacent second terminals 6 to ensure the consistency of electrical connection. And since there may be no corresponding insulating substance provided between adjacent second terminals 6. Therefore, attention should be paid to the spacing width between adjacent second terminals 6 to avoid problems such as signal interference during data transmission.

[0095] In summary, for the mating connector provided in this embodiment, the independently provided first mating housing and second mating housing are elastically connected to the base through the support arm, and the second terminals are elastically arranged between the first mating housing and the second mating housing. When the first mating housing and the second mating housing have a large deviation or offset in the height direction, the mating connector can still ensure the effectiveness of the overall structure and the stability of electrical connection within the allowable design range.

[0096] Embodiment 3:

[0097] Please refer to Figures 1 - 10 on the basis of Figure 11 . This embodiment provides a floating connector assembly 300, which includes the connector 100 in Embodiment 1 and the mating connector 200 in Embodiment 2, and the connector 100 is inserted into the mating connector 200 in a mating manner. As Figures 12 - 13 shown, a structural insert core 441 is provided in the middle of the third chamber 44, and the second contact portion 611 is arranged on the periphery of the structural insert core 441. When the connector 100 is inserted into the first mating housing 4, one end of the connector 100 is inserted into the third chamber 44, and the structural insert core 441 extends into the first chamber 13. Thus, the second contact portion 611 abuts against the first contact portion 32 to achieve the electrical connection between the connector 100 and the mating connector 200.

[0098] When there is a certain offset in the height direction Z between the connector 100 and the mating connector 100, or when there is a positional offset between the circuit boards connected to the two, the connector 100 can drive the first mating housing 4 to move downward relative to the second mating housing 5 in the height direction Z. At this time, the connector 100 and the first mating housing 4 form a relatively stationary state. The first contact portion 32 and the second contact portion 611 do not produce relative sliding, or the sliding distance is negligible, effectively reducing the plating wear at the contact positions of the first terminal 3 and the second terminal 6, thereby improving the service life of the connector assembly. During the high-frequency and high-speed data transmission process, the reduced displacement amount between the first contact portion 32 and the second contact portion 611 can improve the stability and effectiveness during the transmission process. Data transmission problems caused by the positional floating between circuit boards, such as signal interference and signal loss, will be significantly suppressed.

[0099] Since the support arm 43 is elastically connected to the base 51, the two ends of the elastic second terminal 6 are respectively arranged between the first mating housing 4 and the second mating housing 5. The off-load generated by the relatively stationary connector 100 and the first mating housing 4 is elastically absorbed, and the second terminal 6 can better follow after deformation, so that the connection between the connector 100 and the mating connector 200 remains effective.

[0100] In some other embodiments, there is also a longitudinal gap 45 between the first mating housing 4 and the second mating housing 5 in the longitudinal direction Y. After the connector 100 is inserted into the first mating housing 4, if there is an offset in the longitudinal direction Y, the first mating housing 4 can also generate a certain deformation in the longitudinal direction Y to absorb the error and variable load generated in this direction.

[0101] In summary, for the floating connector assembly provided by the present invention, after the connector is inserted into the mating connector, since the first mating housing and the second mating housing form a floating connection, even if there is a large error value in the static connection position between the connector and the mating connector, or there is relative displacement between the circuit boards during the operation of the device, the connector can still maintain a relatively stationary connection state with the first mating housing, and the connection positions of the first terminal and the second terminal remain basically unchanged, avoiding the situation of virtual connection or unstable transmission, and improving the safety and service life of data transmission.

[0102] The above content is only an example and illustration of the structure of the present invention. Its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these obvious replacement forms all belong to the protection scope of the present invention.
