Description

[Technical field]

[0001] The present invention relates to the technical field of floating board-to-board connections, and in particular to a floating connection conductor, a floating electrical connector, and an on-board electronic device.

[0002] The present invention claims priority based on a Chinese patent application with application number 2021107410134, filed with the China Patent Office on June 30, 2021, the entire contents of which are incorporated herein by reference. [Background technology]

[0003] A board-to-board connector is a miniature coupling plug and socket that can directly connect or communicate power and signals between printed circuit boards by the pins of the connector. With the rapid development of electronic products, board-to-board connectors are widely used in many fields such as consumer, industrial control, automobile, medical, and communication. With the development of miniaturization and integration of electronic devices in these fields, more and more functional modules are integrated into a limited space. Therefore, the application environment of these modules is also becoming more and more complex, often including high temperature, complex vibration environment, large processing error environment, etc. When realizing the interconnection of power or signals through different circuit boards, in a complex application environment, the conductor of the connector is often subjected to a strength and stress that exceeds the strength and stress that the connector material itself can withstand, which may cause an instantaneous interruption of the connector electrical signal or the attenuation or destruction of the performance of the connector material itself. In the technical field of floating board-to-board connection, in addition to the complex changes in application scenarios and the integration of multiple modules, the development trend of electronic products shows that the signals used are evolving toward 10Gbps or even higher frequencies, which places higher requirements on the connector transmission speed in connection scenarios using board-to-board connectors. In other words, the connector transmission speed in connection scenarios using board-to-board connectors is also one of the important factors in whether the system can achieve its functions.

[0004] Conventional board-to-board connectors do not have the ability of stable electrical connection when the deviation of the center of the mutual insertion surface between the plug connector and the socket connector is more than ±0.2mm. Therefore, when using conventional board-to-board connectors in a high vibration environment, or when the corresponding contact area operates in a low temperature environment below -20℃ or a high temperature environment above 85℃, problems such as data transmission failure and even connector damage will occur. In application scenarios such as automobiles traveling at high speed on bumpy roads, CT scans running rapidly, and ultrasonic probes interconnecting between multi-layer boards, it is very easy for the electrical connection of the contact area to be cut off instantly, which poses safety risks and is prone to accidents.

[0005] Therefore, there is a need for continuing improvements in the floating connections employed between plug and socket connectors to provide a stable electrical connection. Summary of the Invention [Problem to be solved by the invention]

[0033] In one embodiment of the present invention, the floating connection conductor includes a welded portion, a base fixing portion, a suspended floating portion, a floating fixing portion, and a contact portion, which are connected in sequence. The welded portion is used for welding to a circuit board. The base fixing portion is used for fixing to a base body. The floating fixing portion is used for fixing to a floating body. The contact portion is used for conductively abutting to a plug connector. The suspended floating portion is located between the base fixing portion and the floating fixing portion, and is used for bending to form a suspended sector. The space occupied by the suspended sector is limited by a predetermined width. According to the above floating connection conductor, on the one hand, it is advantageous to stably connect the base body to the circuit board by fixing the base body by the base fixing portion and welding the circuit board by the welded portion, and on the other hand, it is advantageous to stably connect the plug connector to the floating connection conductor by abutting the plug connector by the contact portion to realize electrical continuity. In addition, the design of the suspended sector allows the suspended floating part to realize the floating connection between the plug connector and the base body and the circuit board, which is advantageous in withstanding mechanical loads in a complex application environment of high frequency vibration environment and high acceleration mechanical shock, so that it can be applied to connectors in application scenes with low rate signals, large currents, and very large floating tolerance capabilities. In addition, the suspended sector occupies a limited space and is suitable for arranging multiple floating connection conductors, so that it achieves an effective vibration damping effect in a vibration environment. In addition, the deformation ability of the suspended floating part and its suspended sector can effectively ensure the effective connection and signal conduction between the conductor structure and the plug conductor when the floating connection conductor is applied to board-to-board connection. In addition, the floating connection conductor has a simple structure, so that it is suitable for operation in a certain low temperature environment and high temperature environment.

[0034] In one embodiment, the floating connection conductor includes some or all of the structures of the following embodiments, i.e., the floating connection conductor includes some or all of the following technical features. In one embodiment, the floating connection conductor includes a welded part, a base fixing part, a suspended floating part, a floating fixing part, and a contact part, which are connected in order. In one embodiment, the welded part and the base fixing part are integrally configured, and / or the floating fixing part and the contact part are integrally configured, or the welded part, the base fixing part, the suspended floating part, the floating fixing part, and the contact part are integrally configured. In one embodiment, the floating connection conductor is manufactured by press punching, i.e., the welded part, the base fixing part, the suspended floating part, the floating fixing part, and the contact part are integrally formed by press punching. With this design, the floating connection conductor can withstand mechanical loads in complex application environments of high frequency vibration and high acceleration mechanical shock, and is especially suitable for connectors in application scenarios with low rate signals, large currents, and very large floating tolerance capabilities.

[0035] In order to make full use of materials and not waste them, in one embodiment, the floating connection conductors are entirely located within a rectangle or a circle before being folded to form the suspended sectors.Furthermore, in one embodiment, the floating connection conductors are entirely located within a square before being folded to form the suspended sectors, that is, the area occupied by each floating connection conductor is covered by one square.This design is favorable for full use of materials, and a large number of floating connection conductors can be regularly arranged and then produced by press punching, which avoids waste of materials and improves production efficiency.

[0036] In order to improve the vibration resistance performance, in one embodiment, the area occupied by the suspended floating part is greater than 23% of the total area of ​​the floating connection conductor. In one embodiment, the area occupied by the suspended floating part is greater than 30% of the total area of ​​the floating connection conductor. In one embodiment, the area occupied by the suspended floating part is greater than 40% of the total area of ​​the floating connection conductor. In one embodiment, the area occupied by the suspended floating part is greater than 50% of the total area of ​​the floating connection conductor. In one embodiment, the area occupied by the suspended floating part is adjusted according to the number of folding shapes, and the more folding shapes there are in the same area area, the larger the area occupied by the suspended floating part. This is a design to match the press punching molding, and it is understood that the larger the suspended floating part is, the larger the suspended sector is, which is favorable to improving the vibration energy damping effect, and ensures that the vibration resistance performance is improved and has sufficient vibration damping effect in a vibration environment. In one embodiment, the floating connection conductor is formed by press punching and is manufactured by at least one folding. In one embodiment, the suspended floating section is folded to form the suspended sector. In one embodiment, the floating connection conductor is formed by press punching and is manufactured by two or more folding. This design simplifies the production process of the floating connection conductor, greatly improves the production efficiency of the floating connection conductor, and also ensures the vibration damping effect.

[0037] In order to facilitate the mounting and fixing of the floating connection conductor, in one embodiment, the welded portion is used for welding to a circuit board. In one embodiment, the welded portion includes a connection region and a welding region that are connected, and the connection region and the welding region are configured to be folded and connected to the connection region and the base fixing portion. Furthermore, in one embodiment, the connection region is perpendicular to the welding region, and the welding region is parallel to the circuit board, i.e., a first folding line, which is a folding line of the connection region and the welding region, is parallel to the circuit board. Furthermore, in one embodiment, a folding region, i.e., a first folding region, is formed at the folding point of the connection region and the welding region. Such a design is advantageous for stably connecting the floating connection conductor to the circuit board.

[0038] In order to facilitate the installation and fixing of the base body of the socket connector, in one embodiment, the base fixing part is fixed to the base body. In one embodiment, the base fixing part is inserted into and fixed to the base body, or is interference-fitted, so that the base body is fixed to the circuit board by the floating connection conductor. Furthermore, in one embodiment, the base fixing part is perpendicular to the welding area. Such a design is advantageous for fixing the base body of the socket connector to the circuit board.

[0039] In order to facilitate the realization of floating connection and the connection and conduction of the plug connector, in one embodiment, the floating fixing part is fixed to the floating body, and the contact part is used to abut conductively with the plug connector. In one embodiment, the contact part is removably inserted into the plug connector and is used to abut conductively with the plug connector. Furthermore, in one embodiment, in order to enhance the stability of the fixation, a shape-changing part is provided on the base fixing part and / or the floating fixing part. In one embodiment, the shape-changing part has a concave-convex structure, a screw structure, or a step structure to improve the stability of the installation. With such a design, the contact part abuts the plug connector to realize conduction, which is advantageous for stably connecting the plug connector to the floating connection conductor, and the fixation of the floating body is completely dependent on the floating fixing part, so that the plug connector abuts and conducts with the contact part under the restriction of the floating body.

[0040] In order to realize the damping of vibration energy, in one embodiment, the suspended floating part is located between the base fixing part and the floating fixing part, and is used to bend to form a suspended sector, and the space occupied by the suspended sector is limited by a predetermined width. In one embodiment, the suspended floating part is bent to form the suspended sector. Furthermore, in one embodiment, the suspended sector is in a floating state, i.e., does not contact, especially does not make hard contact with other parts. In one embodiment, the predetermined width is 0.5mm to 3.5mm. Furthermore, in one embodiment, the predetermined width is determined according to the design standard of the socket connector or the floating connection conductor set, or the predetermined width is set and adjusted according to the requirements of the signal transmission of the floating connection. With such a design, the suspended sector realizes the floating connection between the plug connector and the base body and the circuit board through the suspended floating part, so that it has an effective vibration damping effect in a vibration environment. In addition, the deformation ability of the suspended floating part and its suspended sectors can effectively ensure the effective connection and signal conduction between the conductor structure and the plug conductor when the floating connection conductor is applied to board-to-board connection. In a specific application, a plurality of the floating connection conductors together usually form a floating connection conductor set, so if the space occupied by the suspended sectors is too large, it will directly affect the volume of the floating connection conductor set, and the adjacent floating connection conductors are likely to contact each other and cause signal errors, and in serious cases, it will lead to traffic accidents or production accidents, and material losses and even affect the safety of human life. In each embodiment of the present invention, the space occupied by the suspended sectors is cleverly limited by a predetermined width to ensure that the floating state and vibration section of the suspended floating part, especially the suspended sector, is limited, and does not interfere with other suspended floating parts or their suspended sectors, so as to strongly guarantee the accurate and high-speed transmission of large amounts of data. In addition, such a floating connection conductor has a simple structure and is suitable for operation in a certain low temperature environment and high temperature environment.

[0041] In order to enhance the vibration damping effect, in one embodiment, the floating fixing part and the suspended floating part are configured to be folded. In one embodiment, the floating fixing part and the welding area form an angle of 75 degrees to 105 degrees. Furthermore, in one embodiment, the floating fixing part is perpendicular to the welding area. With this design, at least three bending areas are formed, that is, there are at least three direction change conductive areas. The vibration force at the contact point between the floating body and the plug connector is damped by at least three direction changes and at least one suspended sector to the contact point between the base body and the circuit board, and the suspended sector in the floating state is advantageous for cushioning and shock absorption in a high vibration environment, and avoids the hard transmission of vibration. In addition, since the entire floating connection conductor is a conductor, it is advantageous to be suitable for a certain vibration environment in a certain low temperature environment and a certain high temperature environment, ensures the accuracy of signal transmission, avoids the problem of packet loss in a large amount of data transmission, and is particularly suitable for high-speed signal transmission. In each embodiment, the vibration frequency of the vibration environment is 2000 Hz or less, and the acceleration is 150 m / s 2 The temperature of the low temperature environment is -55°C or higher. The temperature of the high temperature environment is +125°C or lower. That is, the high and low temperature environments are application environments of -55°C to +125°C, and the operating environment of the floating connection conductor can cover a wide temperature range of -55°C to +125°C. In actual testing, the prototype can achieve a floating of ±1.0mm to ±1.5mm and can transmit multiple 3A DC currents. Therefore, the floating connection conductor according to the embodiment of the present invention can achieve a very large floating tolerance capability within a limited design dimension and space.

[0042] In order to meet the restrictions on the shape of the contact portion or the floating fixed portion, in one embodiment, the space occupied by the suspended sector is limited by the width of the contact portion. In this embodiment, the width of the contact portion is the predetermined width. Furthermore, in one embodiment, the floating fixed portion and the suspended floating portion are configured to be folded and have a folding angle, and the space occupied by the suspended sector is limited by the width of the contact portion and the folding angle. In one embodiment, the floating fixed portion and the suspended floating portion are configured to be folded, the floating fixed portion is perpendicular to the welding area, and the space occupied by the suspended sector is limited by the width of the contact portion. Furthermore, in one embodiment, the space occupied by the suspended sector is limited by the maximum width of the contact portion and the floating fixed portion. That is, the maximum width of the contact portion and the maximum width of the floating fixed portion is set to the maximum width of the space occupied by the suspended sector, whichever is larger, to prevent the suspended sector from contacting other floating connection conductors during operation, e.g. vibration. In one embodiment, the space occupied by the bent areas where the suspended floating portion is bent to form the suspended sector is also limited by the width of the contact portion, or the space occupied by the floating sectors of the suspended floating portion and the suspended sectors is limited by the width of the contact portion and also by the sum of the lengths of the contact portion and the floating fixed portion. In one embodiment, the space occupied by the bent region where the suspended floating part is bent to form the suspended sector is also limited by the maximum width of the contact part and the floating fixed part, or the space occupied by the floating sector of the suspended floating part and the suspended sector is limited by the maximum width of the contact part and the floating fixed part, and also limited by the sum of the length of the contact part and the floating fixed part. With this design, the space occupied by the suspended sector is cleverly limited by the contact part and the floating fixed part together, so that the vibration space is reasonably formed, and the multiple floating connection conductors do not interfere with each other during operation, which is favorable to guarantee the high-speed transmission of a large amount of data, and the floating connection conductor is suitable for a vibration environment, especially a low-speed vibration environment.

[0043] In one embodiment, the connection region and the welding region are configured to be folded to have a first folding line, the floating fixing part and the suspended floating part are configured to be folded to have a second folding line, and the second folding line and the first folding line form an angle of 75 degrees to 105 degrees. In order to facilitate control of the folding direction and to avoid the occurrence of unnecessary extrusion protrusions, in one embodiment, the floating connection conductor has a first folding opening left in advance at a portion close to the suspended floating part at the folding point between the connection region and the welding region, and / or the floating connection conductor has a second folding opening left in advance at a portion close to the contact part at the folding point between the floating fixing part and the suspended floating part. In one embodiment, the welding portion includes a connected connection region and a welding region, the connection region and the welding region are configured to be folded, the connection region is connected to the base fixing portion, the floating fixing portion and the suspended floating portion are configured to be folded, the base fixing portion is inserted into and connected to a base body of the socket connector and fixed thereto or is interference-fitted, the contact portion is removably inserted into the plug connector and is used to abut electrically conductively against the plug connector, the floating fixing portion and the contact portion are integrally configured, or the welding portion, the base fixing portion, the suspended floating portion, the floating fixing portion, and the contact portion are integrally configured. Here, the connection region and the welding region are configured to be folded to have a first folding line, the floating fixing part and the suspended floating part are configured to be folded to have a second folding line, and the second folding line and the first folding line form an angle of 75 degrees to 105 degrees. The floating connection conductor has a first folding opening left in advance at a portion close to the suspended floating part at the folding point between the connection region and the welding region, and the floating connection conductor has a second folding opening left in advance at a portion close to the contact part at the folding point between the floating fixing part and the suspended floating part. Other embodiments are similar, so the description thereof will not be repeated.

[0044] 1, the floating connection conductor includes a welding part 100, a base fixing part 200, a suspended floating part 300, a floating fixing part 400, and a contact part 500, which are connected in sequence. Furthermore, in this embodiment, the floating connection conductor is fixed to the base body by the base fixing part 200, so that a gap 210 is formed between the base fixing part 200 and the suspended floating part 300.

[0045] In one embodiment, the floating connection conductor or its suspended floating part is formed by a press punching process and a folding process. Specifically, a punching area is formed by a combination of a circular arc and a straight line by press punching. Among the adjacent straight line segments in the punching area, there is at least one part where the angle between the adjacent straight line segments is greater than 0 degrees and less than 90 degrees. After punching, the punching area is folded and shaped by at least one folding, and the terminal in the punching area is folded into a spring-like structure to achieve vibration damping. The folding can be to the same side or in both forward and reverse directions. That is, the method of realizing the floating connection conductor is punching + folding, and the folding direction includes but is not limited to simultaneous up, simultaneous down, and up + down, and includes various punching and folding for terminals of other shapes.

[0046] In one embodiment, the suspended floating part includes at least one arc segment and at least one straight line segment. At least one of the arc segments is folded on itself to form at least one suspended sector, and / or at least one of the straight line segments is folded on itself to form at least one suspended sector, and / or at least one of the arc segments and at least one of the straight line segments are folded together to form at least one suspended sector. Here, the arc segment and the straight line segment form an angle of 0 degrees to 150 degrees, or the suspended floating part includes at least two of the straight line segments, and two adjacent straight line segments form an angle of 0 degrees to 90 degrees. As shown in FIG. 1, the suspended floating part 300 includes a first straight line segment 340, an arc segment 350, and a second straight line segment 360 connected in sequence. The extension direction of the first straight segment 340 and the extension direction of the second straight segment 360 form an acute angle. In use, the first straight segment 340 and the second straight segment 360 can be folded together to form a suspended sector including a portion of the first straight segment 340, the entire arc segment 350, and a portion of the second straight segment 360. That is, in this embodiment, one arc segment and two straight segments are folded together to form one suspended sector, and the two straight segments form an acute angle.

[0047] The design of the suspended sector is to minimize vibration energy and avoid the two fixed ends from pulling each other with force. In one embodiment, the number of the suspended sector is at least one. It is understood that in each embodiment, the number of the suspended sector may be greater than one, even more, provided that the structural strength requirements are met. This enhances the vibration energy damping action and improves the vibration damping effect. In one embodiment, the suspended floating part includes a first connection segment, a floating sector, and a second connection segment, which are connected in sequence. The first connection segment is connected to the base fixed part, the second connection segment is connected to the floating fixed part, and the floating sector is folded by itself to form the suspended sector, and / or the floating sector and the first connection segment are folded together to form the suspended sector, and / or the floating sector and the second connection segment are folded together to form the suspended sector. In one embodiment, the floating connection conductor is as shown in Fig. 2, where the suspended floating part 300 includes a first connection segment 310, a floating sector 320, and a second connection segment 330, which are connected in sequence. The first connection segment 310 is connected to the base fixing part 200, and the second connection segment 330 is connected to the floating fixing part 400. In addition, the suspended floating part 300 has a bending position 311 at the connection point between the first connection segment 310 and the floating sector 320, which effectively controls the bending position according to the bending. The floating sector 320 includes a first floating segment 321 and a second floating segment 322 connected to each other, and a circular edge 303 is formed at the connection point between the two, thereby reducing safety risks and avoiding injury to the operator. The first floating segment 321 is connected to the first connecting segment 310, and the second floating segment 322 is connected to the second connecting segment 330. The first floating segment 321 and the second floating segment 322 form a first included angle α, which is an acute angle.

[0048] The suspended floating part 300 is bent to form a suspended sector 302, as shown in FIG. 3. The welded part 100 includes a connection region 110 and a welding region 120 that are connected. The connection region 110 and the welding region 120 are configured to be folded. The connection region 110 is connected to the base fixing part 200. The connection region 110 and the welding region 120 are configured to be folded to have a first folding line RS. The floating fixing part 400 and the suspended floating part 300 are configured to be folded to have a second folding line UV. The second folding line UV and the first folding line RS form an acute angle or a 90 degree included angle. The floating connection conductor has a first folding opening 130 left in advance in a portion of the folding region between the connection region 110 and the welding region 120 near the suspended floating part 300. The floating connection conductor has a second bent opening 410 left in advance in a portion close to the contact portion 500 of the bent region between the floating fixed portion 400 and the suspended floating portion 300 .

[0049] In this embodiment, the connection area 110 and the welding area 120 are folded to form a first folded area 601, the floating fixed part 400 and the suspended floating part 300 are folded to form a second folded area 602. The first connection segment 310 and the first floating segment 321 are folded to form a third folded area 603, and the second floating segment 322 is folded on itself to form a fourth folded area 604. In accordance with the folded suspended sector 302, the welding part 100 is welded to the circuit board to form a first fixed contact, and the contact part 500 and the floating body of the socket connector and the plug connector form a second fixed contact. The force changes its transmission direction after passing through the first bending region 601, the third bending region 603, the suspended sector 302, the fourth bending region 604, and the second bending region 602 between the first fixed contact and the second fixed contact, and the vibration energy is further attenuated by the suspended sector, so that the floating connection conductor of the present invention has an effective vibration attenuation effect in a vibration environment. The floating connection conductor of the present invention can reduce the influence of the vibration of the plug connector on the welding position between the welded portion 100 and the circuit board to an acceptable safety level, which is favorable for ensuring a certain service life in a certain operating environment, so that the floating connection conductor of the present invention is particularly suitable for use in an in-vehicle environment.

[0050] In this embodiment, in order to avoid the extrusion of the solder paste and to leave a position for the solder paste in advance, the welding part 100 is further provided with a pre-deposited groove 140 between the connection area 110 and the welding area 120. This is advantageous for avoiding local protrusions due to bending on the one hand and for accommodating excess solder paste on the other hand.

[0051] 2 and 3 in combination, in this embodiment, the space occupied by the suspended sector 302 is limited by the width W of the contact portion 500, and is also limited by the sum H of the lengths of the contact portion 500 and the floating fixed portion 400. That is, the space occupied by the floating sector 320 and the suspended sector 302 of the suspended floating portion 300 is limited by the width W of the contact portion 500, and is also limited by the sum H of the lengths of the contact portion 500 and the floating fixed portion 400. With this design, after the suspended floating portion 300 is bent, the vibration range of the suspended sector 302 does not exceed the vibration area defined by the width W of the contact portion 500, or does not exceed the area defined by the width W of the contact portion 500 and the interval between each floating connection conductor, thereby avoiding signal transmission errors.

[0052] In one embodiment, the floating connection conductor is as shown in FIG. 4, and the first floating segment 321 and the second floating segment 322 form a second included angle β, which is an acute angle. Furthermore, the difference from the embodiment shown in FIG. 2 is that the first floating segment 321 is parallel to the second connection segment 330, or the included angle between the first floating segment 321 and the second connection segment 330 is less than 5 degrees. On the premise that the structural strength meets the design requirements, in order to increase the length of the suspended sector as much as possible, the first connection segment 310 is provided with a retracted position 312 to avoid the suspended floating part such as the floating sector and / or the second connection segment during press punching, so as to leave as much space as possible for the suspended floating part, so that the suspended floating part occupies a larger area proportion to the total area of ​​the floating connection conductor, thereby improving the vibration resistance performance. Furthermore, the shape of the retracted position 312 is designed according to the shape of the suspended floating part.

[0053] In one embodiment, the line along which the suspended sector is folded is perpendicular, parallel or inclined to the extending direction of the contact portion, and / or the suspended floating portion forms at least one of the suspended sectors by vertical folding, horizontal folding and forward and reverse folding. Furthermore, when the number of suspended sectors is greater than one, two adjacent suspended sectors are spaced apart to avoid the reduction of vibration energy damping effect due to mutual contact. In addition, such a design is advantageous for each floating connection conductor to form vibration damping directions of multiple angles in a three-dimensional space such as a spatial Cartesian coordinate system, and the floating connection conductor can release vibration force in different planes. Therefore, even if an offset amount within a certain range occurs at the center position during board-to-board connection, vibration is released from multiple positions of the floating connection conductor, making it difficult for electrical contact to come off, and effectively ensuring effective connection and conduction between the floating connection conductor and the metal conductive terminal structure. 5, the suspended floating part 300 is folded vertically in both directions to form two suspended sectors, i.e., a portion of the first floating segment 321 is folded together with the second floating segment 322 to form the first suspended sector 306, and the second floating segment 322 is folded together with a portion of the second connecting segment 330 to form the second suspended sector 307. There is a first gap 304 between the first suspended sector 306 and the second suspended sector 307.

[0054] In this embodiment, the line along which the first suspended sector 306 is folded is the same as the line along which the second suspended sector 307 is folded, i.e., both are folded along a straight line HK, which is parallel to the extension direction MN of the contact portion 500. In this embodiment, the straight line HK is perpendicular to the extension direction PQ of the unfolded portion of the first floating segment 321.

[0055] 6, the difference with respect to the embodiment shown in FIG. 5 is that the line along which the first suspended sector 306 and the second suspended sector 307 are folded, i.e. the straight line HK, are inclined in the extension direction MN of the contact part 500. In another embodiment, the suspended floating part forms the two suspended sectors by forward and reverse folding, i.e. the first suspended sector 306 and the second suspended sector 307 are respectively located on either side of the plane formed by the straight line HK and the extension direction PQ of the unfolded part of the first floating segment 321 shown in FIG.

[0056] In one embodiment, the floating connection conductor is as shown in Fig. 7, and the difference with the embodiment shown in Fig. 4 is that the area occupied by the suspended floating part 320 is larger, and the suspended floating part 320 includes a first floating segment 321, a second floating segment 322, a third floating segment 323, and a fourth floating segment 324 connected in sequence. The fourth floating segment 324 is connected to the second connection segment 330, and the extending directions of the first floating segment 321, the second floating segment 322, the third floating segment 323, and the fourth floating segment 324 are parallel to each other, that is, they form an included angle of 0 degrees, that is, the third included angle δ formed by the first floating segment 321 and the second floating segment 322 is 0 degrees.

[0057] 8, the difference from the embodiment shown in FIG. 5 is that the floating connection conductor has four suspended sectors 302, and between the horizontally adjacent suspended sectors 302 there is a first interval 304, and between the vertically adjacent suspended sectors 302 there is a second interval 305. In this embodiment, the connection region 110 and the welding region 120 are folded to form a first folded region 601. The floating fixed part 400 and the suspended floating part 300 are folded to form a second folded region 602. Each floating segment in the floating sector 320 is folded by itself or folded together, or the floating sector 320 and the second connecting segment 330 are folded together to respectively form a third folding region 603, a fourth folding region 604, a fifth folding region 605, a sixth folding region 606, a seventh folding region 607, an eighth folding region 608, a ninth folding region 609, and a tenth folding region 610. With such a design, the floating connecting conductor according to the present invention can additionally block the transmission of vibration in all folding regions, which is favorable for discharging vibration energy, has an effective vibration damping effect in vibration environment, and, together with the self-deformation ability of the suspended floating part and its suspended sector, can effectively ensure the effective connection and signal conduction between the conductor structure and the plug conductor when applied to board-to-board connection.

[0058] In one embodiment, the floating connection conductor is as shown in Fig. 9, and the difference from the embodiment shown in Fig. 7 is that the area occupied by the suspended floating part 320 is smaller, but the angles between the first floating segment 321 and the second floating segment 322, the angles between the second floating segment 322 and the third floating segment 323, and the angles between the third floating segment 323 and the fourth floating segment 324 in the floating sector 320 are all right angles, that is, the fourth angle γ is a right angle. Furthermore, in this embodiment, the floating sector 320 is connected to the first connecting segment 310 and the second connecting segment 330 at right angles, respectively. That is, the angle between the first floating segment 321 and the first connecting segment 310 is a right angle, and the angle between the fourth floating segment 324 and the second connecting segment 330 is a right angle. The other embodiments are similar and therefore will not be described again.

[0059] In one embodiment, the floating electrical connector comprises a plug connector and a socket connector. The socket connector has the floating connection conductor according to any one of the embodiments, and the socket connector further comprises a base body and a floating body. That is, the socket connector has at least two bodies, one being a stationary base body and the other being a movable floating body. The socket connector further comprises a floating connection conductor as a metal conductive connection end. In one embodiment, the socket connector has a floating connection conductor set in which at least three of the floating connection conductors are regularly arranged. The base fixing portion of each of the floating connection conductors in the floating connection conductor set is fixed to the base body, the floating fixing portion is fixed to the floating body, and the contact portion is conductively abutted against the plug connector. With such a design, the base body can be stably attached to the floating connection conductor set without the need for screws or adhesive, which on the one hand facilitates assembly, and on the other hand avoids the interference of screws with high-speed transmission of large amounts of signal data. In addition, the floating body can be stably attached to the floating connection conductor set without the need for screws or adhesives, resulting in an overall easier to assemble and lighter floating electrical connector, which is particularly suitable for the demands of lightweight and compact design in automotive application environments.

[0060] In one embodiment, the plug connector is provided with a protruding guide post. A recess is provided in the floating body, or the base body and the floating body together form a recess. The shape of the protruding guide post is adapted to the shape of the recess in order to guide the protruding guide post to be inserted into the recess from a predetermined orientation. In one embodiment, the base body is provided with a heat dissipation groove, and the welding portion passes through the heat dissipation groove and is exposed to the outside of the base body. In one embodiment, the socket connector has a floating connection conductor set in which at least three of the floating connection conductors are regularly arranged, and the base fixing portion of each of the floating connection conductors in the floating connection conductor set is fixed to the base body, the floating fixing portion is fixed to the floating body, and the contact portion is conductively abutted against the plug connector. The plug connector is provided with a protruding guide post, and a recess is provided in the floating body, or the base body and the floating body together form a recess. The shape of the protruding guide post is adapted to the shape of the recess so as to guide the protruding guide post to be inserted into the recess from a predetermined direction. The base body is provided with a heat dissipation groove, and the welding portion passes through the heat dissipation groove and is exposed to the outside of the base body. Other embodiments are similar, so the description thereof will not be repeated. In this way, the plug connector and the socket connector are movable relative to each other, and essentially the floating body and the base body are movable relative to each other, that is, they are floatingly and detachably connected, and in the case of a circuit board to which the plug connector and the socket connector are connected, it becomes a floating board-to-board connection. That is, the circuit board connected to the plug connector is independent of the circuit board connected to the socket connector, and the two are connected only by a floating connection conductor set, and the effect of floating board-to-board electrical connection can be realized.

[0061] In addition, in one embodiment, the floating body is further engaged and attached to the base body by an engagement member, or the floating body is further engaged and attached to the base body and the circuit board by an engagement member. This design is advantageous to enhance the mounting stability of the floating body, but reduces the vibration damping effect to a certain extent.

[0062] In one embodiment, the floating electrical connector includes a plug connector 700 and a socket connector 600, as shown in Fig. 10. The plug connector 700 includes a protruding guide post 710, an insulating body 720, and a metal conductive terminal set 730. In this embodiment, the protruding guide post 710 is integral with the insulating body 720, or the protruding guide post 710 is a part of the insulating body 720. The metal conductive terminal set 730 includes at least three regularly arranged metal conductive terminals. The number of the insulating body 720 is one or more.

[0063] 11, the socket connector 600 is provided with a floating connection conductor set 620, a socket weld reinforcement leg 630, a base body 640, and a floating body 650. The floating connection conductor set 620 includes at least three floating connection conductors 621 arranged regularly, that is, the socket connector 600 has a floating connection conductor set 620 configured with at least three floating connection conductors 621 arranged regularly. It is understood that the connection between the plug connector and the socket connector requires a plurality, and therefore a large number of floating connection conductors, and each floating connection conductor exists in a three-dimensional environment formed when the plug connector and the socket connector are connected. Therefore, in order to improve the floating vibration damping effect in the three-dimensional environment and to avoid mutual interference, in this embodiment, the predetermined width is defined according to the arrangement interval between the floating connection conductors 621, thereby avoiding the adjacent floating connection conductors from contacting each other during vibration. In each floating connection conductor 621 in the floating connection conductor set 620, its welding part 100 is welded to the pad 810 of the circuit board 800 to fix the floating connection conductor set 620 to the circuit board 800, its base fixing part 200 is fixed to the base body 640 to fix the base body 640 to the circuit board 800 by the floating connection conductor set 620, its floating fixing part 400 is fixed to the floating body 650, and its contact part 500 is conductively abutted to one metal conductive terminal of the plug connector 700, that is, electric conduction is realized by abutment. In this way, on the one hand, the floating body 650 is fixed to the floating connection conductor set 620, and on the other hand, the floating connection conductor set 620 forms an insertion connection position in accordance with the floating body 650, and is connected to the plug connector 700 by insertion connection, and at the same time, a floating board-to-board conductive connection is realized.

[0064] In this embodiment, the socket connector 600 is provided with two sets of floating connection conductor sets 620. The plug connector 700 is provided with two sets of metal conductive terminal sets 730 correspondingly. In order to avoid interference between the differential pairs, as shown in FIG. 11, the pads 810 are arranged with a misalignment, and further, the two sets of floating connection conductor sets 620 are arranged with a misalignment, and the two sets of metal conductive terminal sets 730 are also arranged with a misalignment correspondingly. Furthermore, in one embodiment, among the two sets of floating connection conductor sets arranged with a misalignment, the misalignment distance L1 between the first floating connection conductor of one set of floating connection conductor sets and the first floating connection conductor of the other set of floating connection conductor sets along the extending direction of the arrangement is equal to or greater than the interval L2 or center distance L3 of the floating connection conductors of the same set. For example. The misalignment distance L1 between the first floating connection conductor of one set of floating connection conductors and the first floating connection conductor of the other set of floating connection conductors is equal to the center distance L3 of the floating connection conductors of the same set, i.e., the first floating connection conductor of one set of floating connection conductors faces the second floating connection conductor of the other set of floating connection conductors. For example, the misalignment distance L1 between the first floating connection conductor of one set of floating connection conductors and the first floating connection conductor of the other set of floating connection conductors is equal to or greater than the center distance L3 of the floating connection conductors of the same set, i.e., in the misaligned arrangement, at least one PIN interval is misaligned. Other embodiments are similar, so the description thereof will not be repeated. With such a design, the floating connecting conductor set and the metal conductive terminal are both arranged with a misalignment, which is advantageous for reducing crosstalk between differential pairs arranged shoulder-to-shoulder in the floating electrical connector, and is also advantageous for reducing crosstalk between differential pairs arranged face-to-face in the floating electrical connector, and can ensure that the electrical performance of the floating electrical connector under large mounting tolerance conditions is in a controllable state, and can guarantee high-speed transmission of large amounts of data.

[0065] The base body 640 of the socket connector is provided with a heat dissipation groove 641, a reinforcing leg mounting groove 642, and a mounting area 643. Referring to FIG. 12, FIG. 13, and FIG. 14, the mounting area 643 is used to accommodate the floating body 650 and the floating connection conductor 621 other than the welding part 100. The reinforcing leg mounting groove 642 is used to mount the socket weld reinforcing leg 630. The socket weld reinforcing leg 630 is further welded to the circuit board 800 and is used to enhance the connection stability between the base body 640 and the circuit board 800. In one embodiment, the socket connector is provided with two socket weld reinforcing legs, and one socket weld reinforcing leg is provided at each end of the base body, and the socket weld reinforcing leg is engaged and fixed with the floating body. The welding part 100 of the floating connection conductor 621 passes through the heat dissipation groove 641 and is exposed to the outside of the base body 640. The heat dissipation groove 641 is provided in the welding area of ​​the base body of the socket connector. The design of the heat dissipation groove 641 is favorable to improve the heat dissipation effect inside the base body 640, and a heat dissipation path is formed between the base body of the socket connector and the welding circuit board, which can facilitate the dissipation of heat generated during the docking operation of the floating electrical connector, and can improve the temperature rise of the floating connector.

[0066] Corresponding to the protruding guide post 710 of the plug connector 700, the floating body 650 is provided with a recess 651, or the base body 640 and the floating body 650 together form the recess 651. The shape of the protruding guide post 710 is adapted to the shape of the recess 651 so as to guide the protruding guide post 710 to be inserted into the recess 651 from a predetermined direction. In practical application, referring to Figs. 15, 16 and 17 together, a guide angle is further provided at the end of the protruding guide post 710, and a corresponding guide angle is also provided in the recess 651, so as to control the insertion direction in accordance with each other. The height of the protruding guide post 710 is higher than the height of the insulating body 720, i.e., higher than the height of the tongue portion 740 of the insulating body 720. In order to avoid insertion deviation, the floating body 650 is further provided with a guide protrusion 652 adjacent to the recess 651. The plug connector 700 is provided with a guide groove 741 corresponding to the guide protrusion 652, and the guide groove 741 is located between the protruding guide post 710 and the tongue portion 740. When the plug connector is inserted in a misaligned manner, the design of the protruding guide post 710 and the recess 651, as shown in Figures 18 and 19, on the one hand, makes it difficult for the plug connector to be caught and pulled out, or to cause structural deformation or damage, and on the other hand, is advantageous in guiding the accurate insertion of the plug connector. This design is advantageous on the one hand to ensure accurate docking of the plug connector and the socket connector, and on the other hand, when transmitting a large amount of data at high speed in a vibration environment, even if an offset amount occurs within a certain range at the center position during board-to-board connection, the speed and accuracy of data transmission can be guaranteed.

[0067] In one embodiment, the floating electrical connector is provided with one or two protruding guide posts at both ends of the insulating body of the plug connector. The upper end surface of the protruding guide post is higher than the end surface of the tongue, and a guide angle is provided on the protruding guide post, and a guide groove is provided between the tongue and the protruding guide post. When the plug connector and the socket connector are inserted into each other, the groove is fitted with the guide protrusion structure of the socket connector, so that the final mutual insertion position of the plug connector and the socket connector can be accurately determined. In addition, the guide protrusion is further provided with a guide angle, and a recess is provided at both ends of the floating body of the socket connector. In the process of inserting the plug connector into the socket connector, if the plug connector is inserted out of alignment, the guide design of the plug connector and the socket connector (i.e., the guide groove and the guide protrusion, the protruding guide post and the recess) can guide the plug connector to the correct insertion position, preventing the PIN from being misaligned or displaced during docking. When the plug connector is pulled diagonally, the recesses and guide protrusions at both ends of the floating body of the socket connector, and the protruding guide posts and guide grooves of the plug connector can be separated without interfering with each other, effectively preventing jamming when pulled diagonally.
