Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and more particularly, to a board-to-board connector for connecting two circuit boards. Background Art

[0002] This section provides background information related to the present application but this information does not necessarily constitute prior art.

[0003] An electrical connector is a commonly used connection device for connecting two devices or two electronic components. For example, an electrical connector is required when connecting two printed circuit boards. The electrical connectors commonly used to connect two printed circuit boards are all two-piece plug-in structures, and the two-piece plug-in structures include a male connector and a female connector that fit together. The male connector and the female connector are respectively provided with high-frequency contacts and low-frequency contacts. The high-frequency contacts and the low-frequency contacts are rigidly fixed in the male connector and the female connector, respectively. When two printed circuit boards are connected together through the male connector and the female connector, there is a corresponding relationship between the joint positions of the male connector and the female connector, so the male connector and the female connector can only be joined when the positions are aligned. However, in the actual assembly process, there will be a certain deviation between the male connector and the female connector at the joint position connected to the corresponding circuit board. When this deviation exceeds a certain degree, the contact on the male connector and the corresponding contact on the female connector may no longer be coaxial, affecting the connection reliability.

[0004] Therefore, it is usually required that the male connector and the female connector be aligned with high precision, that is, the relative offset between the male connector and the female connector in the direction perpendicular to the plug-in direction cannot be too large. If the relative offset exceeds the predetermined value, the transmission distance and path between the male connector and the female connector will change, resulting in signal distortion and interference. In addition, the relatively large offset between the male connector and the female connector will also increase the contact area or pressure of the corresponding conductive parts, thereby increasing the friction or pressure between the contact parts, thereby affecting the reliability of the electrical connector.

[0005] Especially in connector applications that require higher precision, such as high-speed transmission and high-frequency signal transmission, it is even more necessary to ensure that the offset of the electrical connector meets the standards.

[0006] Therefore, there is an urgent need for an electrical connector that can achieve more reliable power and signal transmission and at the same time be flexibly connected to accommodate assembly deviations. Utility Model Content

[0088] Next, an exemplary embodiment of the electrical connector according to the present application will be described in detail with reference to the accompanying drawings. For clarity and simplicity of description, a three-dimensional rectangular coordinate system is marked in the figure. Specifically, the electrical connector 1 has a length extending along a first direction Y; a width extending along a second direction X perpendicular to the first direction Y; and a third direction Z perpendicular to both the first direction Y and the second direction X. The first direction Y, the second direction X, and the third direction Z are perpendicular to each other. The first direction Y also refers to the mating direction of the electrical connector with the corresponding mating connector.

[0089] It should be understood that the terms "vertical", "horizontal", "inside", "outside", "front", "back", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0090] According to an exemplary embodiment of the present application, an electrical connector is provided. Figures 1 to 5 As shown, the electrical connector 1 includes: a first shell 10, the first shell 10 is formed to have a cylindrical shape, the first shell has a first opening portion 101 and a second opening portion 102 opposite to the first opening portion 101 in a first direction Y of the first shell; a first interface portion 20, the first interface portion 20 is at least partially arranged in the first shell 10, the first interface portion 20 includes a first conductive element and extends beyond the first opening portion 101 in the first direction; a first support member 30, the first support member 30 is at least partially received in the first shell 10 and positioned close to the first opening portion 101, the first interface portion 20 is fixedly connected to the first support member 30; a first elastic member 40, the first elastic member 40 is arranged between the outer surface of the first support member 30 and the inner surface of the first shell 10, and the first elastic member 40 is deformable to allow the first support member 30 to be offset relative to the first shell 10 in at least one direction of the second direction X and the third direction Z.

[0091] The electrical connector 1 also includes a second interface portion 50, which is at least partially arranged in the first shell 10, and the second interface portion 50 includes a second conductive element and extends beyond the second opening portion 102 in the first direction Y; and a flexible interconnection portion 80, which is arranged between the first interface portion 20 and the second interface portion 50, and electrically connects the first conductive element of the first interface portion 20 with the second conductive element of the second interface portion 50.

[0092] By providing the deformable first elastic member 40, the first supporting member 30 fixedly connected to the first interface portion 20 is allowed to be moved relative to the first housing 10 in the second direction X (eg Figure 5 There is a certain amount of offset (floating) in at least one of the left and right directions (shown in ) and the third direction Z. That is to say, when the first interface portion 20 of the electrical connector 1 is inserted into the corresponding mating connector that mates with the electrical connector 1, in the case where there is a certain position deviation between the electrical connector 1 and the mating connector, the first elastic member 40 can automatically perform position compensation through elastic deformation, and still ensure the good mechanical connection and electrical connection between the electrical connector 1 and the mating connector. The first elastic member realizes a flexible connection and has a certain position compensation and buffering effect during the connection process, thereby improving the connection accuracy and stability between the electrical connector 1 and the mating connector, and at the same time extending the service life of the electrical connector. Therefore, compared with the conventional male connector and the female connector that require high-precision alignment to achieve interconnection, the electrical connector according to the present application uses a flexible connection method to adapt to more complex installation environments.

[0093] The flexible interconnection part 80 of the present application has good bending performance and flexibility, is not easily damaged, and can better withstand vibration and stress. In addition, the flexible interconnection part can provide compensation for the position deviation between the first interface part 20 and the second interface part 50 in at least one of the first direction Y, the second direction X, and the third direction Z, thereby providing a reliable connection and flexible layout design between the first interface part 20 and the second interface part 50, and providing greater flexibility and reliability for the design and manufacture of the electrical connector.

[0094] According to the exemplary embodiment of the present application, Figure 2 As shown, the electrical connector 1 also includes a second support member 60, which is at least partially received in the first shell 10 and positioned close to the second opening portion 102, and the second interface portion 50 is fixedly connected to the second support member 60; and a second elastic member 70, which is arranged between the outer surface of the second support member 60 and the inner surface of the first shell 10, and the second elastic member 70 is deformable to allow the second support member 60 to be offset relative to the first shell 10 in at least one of the second direction X and the third direction Z.

[0095] The second elastic member 70 disposed between the outer surface of the second supporting member 60 and the inner surface of the first shell 10 has substantially the same function as the first elastic member 40.

That is to say, when the second interface portion 50 of the electrical connector 1 is inserted into the corresponding mating connector that mates with the electrical connector 1, in the case where there is a certain position deviation between the electrical connector 1 and the mating connector, the second elastic member 70 can automatically compensate for the position through elastic deformation, and still ensure a good mechanical connection and electrical connection between the electrical connector 1 and the mating connector.

[0115] According to some exemplary embodiments of the present application, a board-end connector 2 is also provided. Fig.10 As shown, the board connector 2 is configured as a female connector and is configured to be connected to a circuit board. The board connector 2 has a height extending along a first direction Y; a width extending along a second direction X perpendicular to the first direction Y; and a thickness extending along a third direction Z perpendicular to both the first direction Y and the second direction X.

[0117] like Figures 11 to 13As shown, a plurality of conductive sub-assemblies may be arranged side by side in a manner spaced apart from each other in the second direction X. Each conductive sub-assembly in the plurality of conductive sub-assemblies may include a pair of first elongated conductive elements 204 facing each other in the third direction Z; and a pair of second elongated conductive elements 206 facing each other in the third direction Z. The dimension of the first elongated conductive element 204 in the first direction Y is greater than the dimension of the second elongated conductive element 206 in the first direction Y, and the proximal end of the first elongated conductive element 204 is formed at the insertion interface of the slot.

[0118] Optionally, each conductive subassembly of the plurality of conductive subassemblies may be identical.

[0119] In this application Fig.12 In the exemplary embodiment shown, four of the plurality of conductive sub-components are formed as power transmission terminals, and the remaining conductive sub-components of the plurality of conductive sub-components are formed as signal transmission terminals.

[0120] It should be understood that the number and arrangement of the power transmission terminals and the signal transmission terminals are not limited to the exemplary embodiments described herein, but may be adjusted according to actual conditions.

[0121] In some exemplary embodiments, Fig.10 As shown, the second housing 201 includes a first protrusion 203 and a second protrusion 205 disposed on opposite sides of the second housing 201 in the second direction X, the dimension of each of the first protrusion 203 and the second protrusion 205 in the first direction Y is smaller than the dimension of the first elongated conductive element in the first direction Y, and each of the first protrusion 203 and the second protrusion 205 is formed with an aperture 207. In the case where the board-end connector 2 is connected to the circuit board through the connecting device, the connecting device will extend through the aperture.

[0122] In some exemplary embodiments, Fig.12 and Fig.13 As shown, each of the first elongated conductive elements 204 may include a first proximal end 231 adjacent to the plug interface, a first distal end 232 opposite to the first proximal end, and one or more bends disposed between the first proximal end and the first distal end. The paired first elongated conductive elements include a first contact portion 234 and a second contact portion 235 adjacent to the first proximal end and protruding toward the second center axis BB of the board-end connector, and the first contact portion and the second contact portion are exposed in the slot 213.

[0123] Each of the second elongated conductive elements 206 may include: a second distal end 262 flush with the first distal end 232 of the first elongated conductive element; a second proximal end 261 opposite to the second distal end, and one or more bends disposed between the second proximal end and the second distal end. The paired second elongated conductive elements 206 include a third contact portion 264 and a fourth contact portion 265 adjacent to the second proximal end 261 and protruding toward the second center axis BB of the board connector, and the third contact portion and the fourth contact portion are exposed in the slot 213.

[0124] It should be understood that the second central axis BB is a side view of the board end connector 2 (eg Fig.13 ) is a central axis that divides the board-end connector 2 into two halves along the first direction Y. It should be understood that the expression "proximal end" used in the description of this application refers to an end adjacent to the mating end of the board-end connector, and the expression "distal end" refers to the other end opposite to the proximal end and away from the mating end of the board-end connector.

[0125] In some exemplary embodiments, the pair of first elongated conductive elements 204 may be mirrored about the second center axis BB of the board header connector 2. The pair of second elongated conductive elements 206 may be mirrored about the second center axis BB of the board header connector.

[0126] In some exemplary embodiments, the distance between the first contact portion 234 of the first elongated conductive element 204 and the third contact portion 264 of the second elongated conductive element 206 in the first direction Y is in the range of 6 mm to 9 mm. The distance between the first contact portion and the third contact portion for transmitting signals is set within the above range to ensure the desired signal integrity performance, thereby avoiding a large product structure caused by an excessively large spacing or a large signal crosstalk caused by an excessively small spacing.

[0127] For example, in some embodiments, the distance between the first contact point 234 and the third contact point 264 in the first direction Y may be in the range of 7 mm to 8.5 mm. Setting the distance between the first contact point 234 and the third contact point 264 in the range of 7 mm to 8.5 mm can balance the signal transmission quality and the product size. Optionally, the distance between the first contact point 234 and the third contact point 264 may be 6 mm, 7 mm, 8 mm, or 8.5 mm.

[0128] In some exemplary embodiments, the first distal end 232 of each first elongated conductive element 204 extends through the mounting end 210 of the second housing 201 and has an L-shape in a cross section perpendicular to the second direction X (eg, Fig.12 and Fig.13The second distal end 262 of each second elongated conductive element 206 extends through the mounting end 210 of the second housing 201 and has a T-shape in a cross section perpendicular to the second direction X (as shown in FIG. Fig.12 and Fig.13 shown).

[0129] It should be understood that the shapes of the first distal end of the first elongated conductive element 204 and the second distal end of the second elongated conductive element 206 are not limited to the exemplary embodiments described herein, but may be adjusted according to actual conditions.

[0130] In some exemplary embodiments, each of the second elongated conductive elements 206 includes a twisting portion 263 disposed between the second proximal end 261 and the second distal end 262, and the twisting portion 263 connects the first band-shaped portion and the second band-shaped portion disposed at opposite ends of the twisting portion 263, so that the normal direction of the main surface of the first band-shaped portion and the normal direction of the main surface of the second band-shaped portion form a twist angle in the range of 0 to 90 degrees. The twisting portion 263 reduces the rigidity of the second elongated conductive element, thereby reducing the insertion force and retention force of the board terminal connector 2.

[0131] The twist angle is set within the range of 0 to 90 degrees so that the contact portion (contact surface portion) of the second elongated conductive element 206 located above the twist portion 263 in the first direction Y can form line contact with the connector (e.g., card) to be inserted into the slot as much as possible to ensure transmission quality. This prevents point contact between the contact surface of the contact portion and the corresponding connector (e.g., card) (caused by an excessively large or small twist angle) because point contact may affect transmission quality.

[0132] Optionally, the twisting angle of the twisting portion may be about 45 degrees, about 80 degrees, or about 90 degrees. In some examples, each of the first elongated conductive element 204 and the second elongated conductive element 206 may be provided with a corresponding twisting portion.

[0133] In some exemplary embodiments, Fig.13 As shown, each first elongated conductive element 204 includes a support arm 245 and an elastic arm 247 disposed between the first proximal end 231 and the first distal end 232. The support arm 245 is adjacent to the first distal end 232 and connected to the elastic arm 247, and each of the first contact portion 234 and the second contact portion 235 is disposed on the elastic arm 247. The elastic arm 247 is inclined relative to the support arm 245.

[0134] The elastic arm 247 may include a main elastic arm 126 and a secondary elastic arm 127, both of which extend from the position where the elastic arm 247 is connected to the support arm 245 in a direction away from the support arm 245, and the main elastic arm 126 and the secondary elastic arm 127 are spaced apart from each other, and each of the first contact portion 234 and the second contact portion 235 is arranged on a side of the main elastic arm 126 that is away from the secondary elastic arm 127.

[0135] Optionally, the length of the main elastic arm 126 is greater than the length of the secondary elastic arm 127 .

[0136] In some embodiments, either or both of the first elongated conductive element 204 and the second elongated conductive element 206 may include a primary elastic arm and a secondary elastic arm, which may be shaped to provide a desired insertion force or retention force for the corresponding contact portions of the first elongated conductive element 204 and the second elongated conductive element 206.

[0137] The elastic arm of the first elongated conductive element 204 is designed as two separate parts, namely the main elastic arm 126 and the secondary elastic arm 127. In this way, when the corresponding mating connector (such as a card) is inserted into the slot of the board-end connector, the resistance generated by the contact portion of the first elongated conductive element can be reduced. Therefore, the user can easily perform the insertion. In addition, there is a gap between the main elastic arm 126 and the secondary elastic arm 127, and the end at which the main elastic arm 126 and the secondary elastic arm 127 are connected is relatively fixed, and the free ends of the main elastic arm 126 and the secondary elastic arm 127 are independent of each other. When the contact portion provided on the main elastic arm 126 is matched with the corresponding conductive pad of the mating connector, the main elastic arm 126 and the secondary elastic arm 127 are elastically deformed, which can effectively absorb a certain amount of impact force, thereby extending the service life of the board-end connector 2.

[0138] In addition, the present application provides an electronic system.

[0139] As described above, the second housing 201 of the first board-end connector 2 includes a first protrusion 203 and a second protrusion 205 disposed on opposite sides of the second housing 201 in the second direction X. The size of each of the first protrusion 203 and the second protrusion 205 in the first direction Y is smaller than the size of the first elongated conductive element 204 in the first direction Y. Each of the first protrusion 203 and the second protrusion 205 is formed with an orifice 207 (such as Fig.10 shown).

[0140] The first support member 30 is provided with mounting holes 31 , 33 extending along the first direction Y through the first support member 30 .

The first board connector 2 is fixedly connected to the first circuit board through the locking portion 51.

The connecting device 5 includes a second stopper 504 spaced apart from the first stopper in the first direction Y.

Thus, the first board-end connector 2 can be firmly mounted to the first circuit board 3 through the threaded connector. This threaded connection is not easy to loosen, has good anti-seismic performance, can withstand large tensile and shear forces, and is easy to disassemble, and is convenient for maintenance and repair.

[0145] The guide portion 52 of the connecting device 5 can be formed as a high-strength guide column to guide the insertion of the electrical connector 1, and can support blind insertion of the electrical connector 1, reducing assembly time, reducing assembly errors and installation costs, thereby improving assembly efficiency and enhancing the convenience of assembly.

The signal transmission contact portion of the first interface portion 20 is connected to the corresponding contact portion of the signal transmission terminal of the first board-end connector 2 to achieve signal transmission between the electrical connector 1 and the first board-end connector. In this way, a reliable power transmission path and a high-quality signal transmission path can be provided between the electrical connector 1 and the first board-end connector 2, thereby meeting the needs of a wider range of electronic communication systems.

[0150] In some exemplary embodiments, each of the first elongated conductive elements of the first board-end connector 2 includes a first proximal end 231 adjacent to the plug interface, a first distal end 232 opposite to the first proximal end, and one or more bends disposed between the first proximal end and the first distal end.

The second row of conductive pads 283 are closer to the free end of the first interface portion 20 than the first row of conductive pads 281.

[0154] like Fig.16 As shown, when the first interface portion 20 of the electrical connector 1 is fitted to the first board-end connector 2, the first contact portion 234 and the second contact portion 235 of each first elongated conductive element engage with the corresponding conductive pad in the first row of conductive pads 281.
