Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector. Background Technology

[0002] In existing technologies, terminal structures are typically designed with a uniform width for each terminal. However, applications supporting fast charging require power and ground terminals to handle larger currents. This is especially true in connector structures with double-layer arrangements, where the space between the upper and lower sets of terminals can be compressed, increasing the risk of electrical short circuits. Furthermore, excessively small terminals can affect insulation performance and assembly precision, making it difficult to achieve stable high-current transmission while ensuring safe insulation, thus limiting the connector's performance improvement in high-power applications. Utility Model Content

[0003] The main purpose of this invention is to provide an electrical connector that improves the current carrying capacity and heat dissipation performance of the terminals.

[0004] To achieve the above objectives, this utility model proposes an electrical connector, comprising:

[0005] An insulating body, wherein the insulating body extends along a first direction;

[0006] A terminal group is provided on the insulating body. The terminal group includes a power terminal and a ground terminal. The power terminal has a first connection portion and a second connection portion connected to the first connection portion. Both the first connection portion and the second connection portion extend along the first direction.

[0007] The grounding terminal has a third connecting portion and a fourth connecting portion connected to the third connecting portion, and both the third connecting portion and the fourth connecting portion extend along the first direction;

[0008] Wherein, the width of the second connecting portion extending in the second direction is greater than the width of the first connecting portion extending in the second direction; and / or

[0009] The width of the fourth connecting portion extending along the second direction is greater than the width of the third connecting portion extending along the second direction.

[0010] The first direction and the second direction are intersecting.

[0011] In one embodiment, the number of terminal groups is two, and the two terminal groups are respectively disposed on both sides of the insulating body.

[0012] In one embodiment, the electrical connector further includes a shielding structure, which includes two first shielding sheets and a second shielding sheet. The two first shielding sheets and the second shielding sheet are both disposed between the two sets of terminal groups, and the two first shielding sheets are symmetrically arranged relative to the second shielding sheet.

[0013] The terminal group also includes a first high-frequency terminal, a signal terminal, and a second high-frequency terminal;

[0014] The grounding terminal includes a first grounding terminal and a second grounding terminal, which are disposed on both sides of the insulating body along the second direction. The power terminal includes a first power terminal and a second power terminal, which are located between the first grounding terminal and the second grounding terminal. The first high-frequency terminal is located between the first power terminal and the first grounding terminal, and the second high-frequency terminal is located between the second power terminal and the second grounding terminal. The signal terminal is located between the first power terminal and the second power terminal.

[0015] The two first grounding terminals are electrically connected to one of the two first shielding sheets, the two second grounding terminals are electrically connected to the other of the two first shielding sheets, and the two first power supply terminals and the two second power supply terminals are electrically connected to the second shielding sheets respectively.

[0016] In one embodiment, the electrical connector further includes a conductive element disposed on the shielding structure and located at the first connection portion, wherein the shielding structure is connected to the grounding terminal through the conductive element.

[0017] In one embodiment, the conductive element includes a first conductive portion and a second conductive portion. The first conductive portion is provided on both sides of the two first shielding sheets, and the second conductive portion is provided on both sides of the second shielding sheet. The two first grounding terminals and the two second grounding terminals are electrically connected to the two first shielding sheets through the first conductive portion, and the two first power supply terminals and the two second power supply terminals are electrically connected to the second shielding sheet through the second conductive portion.

[0018] In one embodiment, the first conductive portion is a protruding structure provided on the first shielding sheet;

[0019] The second conductive part is a protruding structure provided on the second shielding sheet.

[0020] In one embodiment, the terminal group further includes an insulator, with two sets of the terminal group disposed on both sides of the insulator.

[0021] In one embodiment, both the first grounding terminal and the second grounding terminal have the fourth connecting portion, and one end of the two fourth connecting portions away from the third connecting portion is bent and extended along the vertical direction to form a wiring portion;

[0022] The shielding structure has a first abutting arm and a second abutting arm, which are located on both sides of the terminal group and are arranged along the vertical direction.

[0023] In one embodiment, the insulating body includes a base and a tongue plate extending from the base along the first direction, with two sets of terminal groups respectively arranged on both sides of the tongue plate.

[0024] In one embodiment, the electrical connector further includes a shielding housing that covers the insulating body.

[0025] This utility model discloses an electrical connector, including an insulating body and a terminal group. The insulating body is the basic supporting structure of the entire electrical connector, extending along a first direction. This first direction can be understood as the length direction of the connector's main body, such as the insertion direction of a plug or socket or the longitudinal axis direction. The insulating body is made of insulating material, serving to fix the internal metal terminals and prevent short circuits. The terminal group, disposed on the insulating body, is a key component for realizing the electrical connection function. The terminal group includes two main types of terminals: power terminals and ground terminals. Power terminals are used to transmit operating current or voltage, while ground terminals are used to provide a grounding path, ensuring electrical safety and signal integrity. The power terminal consists of two parts: a first connecting part and a second connecting part, both extending along the first direction. That is, the entire power terminal has a linear or near-linear layout, facilitating integration into the insulating body. The first connecting part is located near the front end (contact end) of the connector, used for conductive contact with the mating connector; the second connecting part is located at the rear end (tail end), used for soldering or crimping wires to a circuit board. The ground terminal also includes a third connecting part and a fourth connecting part, both extending along the first direction. This indicates that the overall structure of the grounding terminal is similar to that of the power terminal, featuring a segmented design. The width of the second connection portion in the second direction is greater than that of the first connection portion in the second direction. Here, the second direction should be understood as perpendicular to the first direction, and could be the lateral width direction of the connector. In other words, a portion of the power terminal (which can be understood as the rear end) is wider than the front end. This design increases the cross-sectional area of ​​that portion, thereby improving current carrying capacity, reducing resistance, enhancing heat dissipation, or increasing mechanical strength. Similarly, the width of the fourth connection portion in the second direction is also greater than that of the third connection portion. This indicates that the grounding terminal also employs a variable cross-section design, with the rear end being wider than the front end. Since grounding terminals typically need to carry large transient currents or provide low-impedance loops, widening a specific portion helps improve electromagnetic compatibility (EMC) performance, reduce ground bounce, and enhance overall connection stability. The use of the word "and / or" in the design suggests that these two width variations can coexist, or only one of them can exist. That is, the electrical connector can employ a widened design only on the power terminal, or only on the ground terminal, or both, providing design flexibility to be adjusted according to actual application requirements. This variable-width design is intended to improve the current-carrying capacity and heat dissipation performance of the terminals. When current flows through a terminal, Joule heating is generated. The wider portion has a larger cross-sectional area and lower resistance, thus reducing heat generation and increasing current carrying capacity. Especially in paths requiring high current transmission, such as power supplies and grounding, widening the rear end helps cope with high power demands and prevents material aging or connection failure due to localized overheating.

[0036] This utility model proposes an electrical connector.

[0037] Reference Figures 1-3 In this embodiment of the present invention, an electrical connector includes:

[0038] An insulating body 10 is provided extending along a first direction;

[0039] Terminal group 20 is disposed on the insulating body 10. The terminal group 20 includes a power terminal 21 and a ground terminal 22. The power terminal 21 has a first connection portion 211 and a second connection portion 212 connected to the first connection portion 211. Both the first connection portion 211 and the second connection portion 212 extend along the first direction.

[0040] The grounding terminal 22 has a third connecting portion 221 and a fourth connecting portion 222 connected to the third connecting portion 221, and both the third connecting portion 221 and the fourth connecting portion 222 extend along the first direction;

[0041] Wherein, the width of the second connecting portion 212 extending in the second direction is greater than the width of the first connecting portion 211 extending in the second direction; and / or

[0042] The width of the fourth connecting portion 222 extending along the second direction is greater than the width of the third connecting portion 221 extending along the second direction;

[0043] The first direction and the second direction are intersecting.

[0044] This utility model discloses an electrical connector, including an insulating body 10 and a terminal group 20. The insulating body 10 is the basic support structure of the entire electrical connector, extending along a first direction. The first direction can be understood as the length direction of the connector body, such as the insertion direction of a plug or socket or the longitudinal axis direction. The insulating body 10 is made of insulating material, serving to fix the internal metal terminals and prevent short circuits. The terminal group 20 is disposed on the insulating body 10 and is a key component for realizing the electrical connection function. The terminal group 20 includes two main types of terminals: power terminals 21 and ground terminals 22. They respectively perform the functions of power transmission and grounding circuit. The power terminals 21 are responsible for introducing external power into the device and typically need to carry a large operating current; while the ground terminals 22 are used to establish a low-impedance reference potential path, which helps to suppress electromagnetic interference, improve signal integrity, and ensure user safety. Both types of terminals are integrated on the insulating body 10, forming a complete conductive path. The power terminals 21 consist of two parts: a first connecting part 211 and a second connecting part 212, both of which extend along the first direction. In other words, the entire power terminal 21 has a linear or near-linear layout, facilitating integration into the insulating body 10. The first connecting portion 211 can be located near the front end (contact end) of the connector for conductive contact with the mating connector; the second connecting portion 212 can be located at the rear end (tail end) for soldering or crimping wires to the circuit board. The ground terminal 22 also includes a third connecting portion 221 and a fourth connecting portion 222, both of which extend along the first direction. This indicates that the overall structure of the ground terminal 22 is similar to that of the power terminal 21, featuring a segmented design. This segmented design suggests that the terminal is not a uniform cross-section but is constructed differently according to the needs of different functional areas. The width of the second connecting portion 212 in the second direction is greater than the width of the first connecting portion 211. The second direction should be understood as the transverse direction perpendicular to the first direction, i.e., the direction of widening of the terminal in cross-section. That is, the power terminal 21 exhibits a stepped or tapered expansion structure that is narrower at the front and wider at the back. Similarly, the fourth connecting portion 222 of the ground terminal 22 is also wider than the third connecting portion 221, exhibiting the same widening trend. The use of "and / or" in the design indicates that this widened design can be applied alone to power terminal 21, alone to ground terminal 22, or both simultaneously, demonstrating design flexibility. Depending on the specific application requirements, engineers can choose to strengthen only the power path, only the ground loop, or optimize both simultaneously to achieve the best cost-effectiveness and performance balance. This variable width design aims to improve the terminal's current-carrying capacity and heat dissipation. Joule heating occurs when current passes through the terminal. The wider portion has a larger cross-sectional area and lower resistance, thus reducing heat generation and increasing current carrying capacity. Especially in paths requiring high current transmission, such as power terminal 21 and ground terminal 22, widening the rear end helps cope with high power demands and prevents material aging or connection failure due to localized overheating.Overall, this solution optimizes the electrical and mechanical properties of the terminals by using connection portions of varying widths in the power terminal 21 and / or ground terminal 22. Wider portions can be used to improve conductivity, enhance structural strength, or improve welding reliability, while narrower portions may be beneficial for saving space, reducing material costs, or facilitating dense arrangement.

[0045] Reference Figures 1-3 In this embodiment of the present invention, there are two sets of terminal groups 20, which are respectively disposed on both sides of the insulating body 10.

[0046] The electrical connector comprises two terminal groups 20, each containing a complete sequence of functional terminals, including power terminals 21 and ground terminals 22. By arranging the terminal groups 20 on both sides, the connector's terminal density and signal transmission capability per unit space are significantly improved. The connector achieves double-sided terminal arrangement on the insulating body 10, fully utilizing the lateral (i.e., plane perpendicular to the first direction) space resources of the insulating body 10 and avoiding the space waste associated with arranging terminals on only one side. As the carrier of the terminal groups 20, the insulating body 10 effectively isolates the electrical connection between adjacent terminals, preventing short circuits, and provides mechanical support, enhancing the terminals' resistance to bending and deformation during insertion and removal.

[0047] Reference Figures 1-3 In this embodiment of the present invention, the electrical connector further includes a shielding structure 30, which includes two first shielding sheets 31 and a second shielding sheet 32. The two first shielding sheets 31 and the second shielding sheet 32 ​​are both disposed between the two sets of terminal groups 20, and the two first shielding sheets 31 are symmetrically arranged relative to the second shielding sheet 32.

[0048] The terminal group also includes a first high-frequency terminal 23, a signal terminal 24, and a second high-frequency terminal 25;

[0049] The grounding terminal 22 includes a first grounding terminal 223 and a second grounding terminal 224, which are disposed on both sides of the insulating body 10 along the second direction. The power terminal 21 includes a first power terminal 213 and a second power terminal 214, which are located between the first grounding terminal 223 and the second grounding terminal 224. The first high-frequency terminal 23 is located between the first power terminal 213 and the first grounding terminal 223. The second high-frequency terminal 25 is located between the second power terminal 214 and the second grounding terminal 224. The signal terminal 24 is located between the first power terminal 213 and the second power terminal 214.

[0050] The two first grounding terminals 223 are electrically connected to one of the two first shielding plates 31, the two second grounding terminals 224 are electrically connected to the other of the two first shielding plates 31, and the two first power supply terminals 213 and the two second power supply terminals 214 are electrically connected to the second shielding plate 32 respectively.

[0051] Specifically, the connector includes an insulating body 10, a terminal group 20 disposed thereon, and a shielding structure 30 formed by connecting two first shielding plates 31 and a second shielding plate 32. The terminal group 20 has a clear functional division in its composition and sequence: the outermost terminals are the first grounding terminal 223 and the second grounding terminal 224, with the first power terminal 213 and the second power terminal 214 disposed between them; a first high-frequency terminal 231 is disposed between the first grounding terminal 223 and the first power terminal 213, and a second high-frequency terminal 25 is disposed between the second power terminal 214 and the second grounding terminal 221; and multiple signal terminals 24 are concentrated between the two power terminals 21. This arrangement forms a structural layout with the power terminals 21 and the signal terminals 24 as the center, the high-frequency terminals as the transition, and the grounding terminals 22 as the boundary. More importantly, the shielding structure 30 achieves specific electrical connections with each functional terminal: the two first grounding terminals 223 are respectively connected to one of the two first shielding plates 31, and the two second grounding terminals 224 are respectively connected to the other of the two first shielding plates 31. That is, each first shielding plate 31 is connected to the system through the grounding terminal 22, playing an active shielding role, which can effectively absorb and discharge electromagnetic noise from adjacent terminal groups 20, especially suppressing crosstalk between adjacent signal pairs. The two first power supply terminals 213 and the two second power supply terminals 214 are electrically connected to the middle second shielding plate 32, so that the second shielding plate 32 can not only provide mechanical support and structural integrity, but also serve as a low-impedance power supply path, supplying power to multiple power supply terminals 21 in parallel, reducing power path impedance, enhancing power integrity, and contributing to the efficient operation of decoupling capacitors.

[0052] Reference Figures 1-3 In this embodiment of the present invention, the electrical connector further includes a conductive element 40, which is disposed on the shielding structure 30 and located at the first connecting portion 211. The shielding structure 30 is connected to the grounding terminal 22 through the conductive element 40.

[0053] Specifically, the electrical connector also includes a conductive element 40 disposed on the shielding structure 30. This conductive element 40 is located in the area corresponding to the first connection portion 211 of the power terminal 21, and its core function is to achieve a conductive connection between the shielding structure 30 and the grounding terminal 22, thereby achieving a conductive connection between the grounding terminals 22 of the two sets of terminal groups 20. In other words, although the shielding structure 30 itself already has a partial electrical connection with the first grounding terminal 223 and the second grounding terminal 224 through two first shielding sheets 31, this solution adds the conductive element 40 to establish an additional low-impedance grounding path at a specific location on the shielding structure 30 (such as near the first connection portion 211), enabling the entire shielding structure 30 to form a more stable and reliable electrical connection with the grounding terminal 22. The main purpose of this design is to solve the common problem of unstable shielding effectiveness in high-speed, high-frequency connectors: under high-frequency operating conditions, electromagnetic interference energy is strong. If the grounding path of the shielding structure 30 has excessively high impedance or poor contact, it can easily lead to a decrease in shielding effectiveness, causing signal radiation or crosstalk. By setting independent conductive elements 40, it is possible to ensure that the shielding structure 30 maintains a good connection with the system ground (i.e., grounding terminal 22) at multiple points, forming a multi-point grounding or enhanced grounding loop, thereby significantly reducing the overall grounding impedance of the shielding system and improving its ability to discharge electromagnetic interference. Furthermore, the conductive elements 40 are typically made of a metal material with good conductivity and elasticity, which can maintain stable contact pressure during connector insertion and removal, preventing contact failure due to vibration or thermal expansion and contraction, and improving the long-term reliability of the product. At the same time, placing the conductive elements 40 near the first connection portion 211 also helps to build a local shielding closed loop around the power terminal 21, a potential noise source, suppressing the coupling of power supply noise to the signal area.

[0054] Reference Figures 1-3 In this embodiment of the present invention, the conductive member 40 includes a first conductive part 41 and a second conductive part 42. The first conductive part 41 is provided on both sides of the two first shielding plates 31, and the second conductive part 42 is provided on both sides of the second shielding plate 32. The two first grounding terminals 223 and the two second grounding terminals 224 are electrically connected to the two first shielding plates 31 through the first conductive part 41, and the two first power terminals 211 and the two second power terminals 212 are electrically connected to the second shielding plate 32 through the second conductive part 42.

[0055] Specifically, the conductive element 40 includes a first conductive portion 41 and a second conductive portion 42. The first conductive portion 41 is disposed on the first shielding plate 31 and ensures a reliable electrical connection between the first shielding plate 31 and the grounding terminal 22; the second conductive portion 42 is disposed on the second shielding plate 32 and ensures effective conductivity between the second shielding plate 32 and the power terminal 21. This design allows both ends of the shielding plate structure 30 to be connected to their respective grounding terminals 22 and power terminals 21 through dedicated conductive components, significantly reducing the overall grounding impedance of the shielding plate and improving its discharge efficiency for high-frequency electromagnetic interference, thereby enhancing electromagnetic shielding performance. Secondly, since electrical connectors may be affected by temperature changes, mechanical vibrations, or insertion and extraction stress during operation, a single grounding connection point is prone to shielding failure due to loose contact or deformation. The dual conductive portion design provides redundant grounding paths, improving the reliability and stability of the electrical connection.

[0056] Reference Figures 1-3 In this embodiment of the present invention, the first conductive part 41 is a protruding structure provided on the first shielding sheet 31;

[0057] The second conductive part 42 is a protruding structure provided on the second shielding sheet 32.

[0058] Specifically, the first conductive part 41 is a protruding structure disposed on the first shielding plate 31, and the second conductive part 42 is a protruding structure disposed on the second shielding plate 32. When the connector is assembled or mated with other components, these protruding structures can directly contact the corresponding grounding terminal 22 and power terminal 21 and maintain a certain elastic pressure, thereby ensuring a stable, low-impedance electrical connection path between the shielding plate structure 30 and the grounding terminal 22. The main purpose of this design is to improve the electromagnetic shielding performance, structural integration, and long-term reliability of the electrical connector. Using protruding structures as conductive parts allows for the integral molding of conductive contacts from the shielding plate structure 30 without adding additional independent parts, simplifying the structural design, reducing the number of parts and assembly complexity, and facilitating miniaturization and high-density layout. Furthermore, protruding structures typically possess a certain degree of elasticity and deformation capability, generating continuous contact pressure when in contact with other terminals, effectively preventing loosening of the contact due to vibration, thermal expansion and contraction, or repeated insertion and removal, ensuring a durable and reliable grounding connection.

[0059] Reference Figures 1-3 In this embodiment of the present invention, the terminal group further includes an insulator 26, and the two terminal groups 20 are disposed on both sides of the insulator 26.

[0060] The insulator 26 serves as the carrier of the terminal group 20, effectively isolating the electrical connection between adjacent terminals, preventing short circuits, and providing mechanical support to enhance the terminals' resistance to bending and deformation during insertion and removal. Furthermore, the insulator 26 is integrally formed with the terminal group 20.

[0061] Reference Figures 1-3 In this embodiment of the present invention, both the first grounding terminal 223 and the second grounding terminal 224 have the fourth connecting portion 222, and one end of the two fourth connecting portions 222 away from the third connecting portion 221 is bent and extended along the vertical direction to form a wiring portion 225;

[0062] The shielding structure 30 has a first abutting arm 34 and abutting arm 35, the first abutting arm 34 and the second abutting arm 35 are respectively located on both sides of the terminal group 20 and are arranged along the vertical direction.

[0063] Specifically, both the first grounding terminal 223 and the second grounding terminal 224 include a fourth connecting portion 222. This fourth connecting portion 222 has a large lateral width (to enhance conductivity and structural strength), and its end away from the third connecting portion 223 is bent vertically to form a dedicated connection portion 225. This connection portion 225 typically extends in an L-shape or U-shape and protrudes vertically. This connection portion 225 serves as an external or connection interface for the grounding terminal 22, and can be used for soldering or crimping with external circuits (such as grounding pads on a PCB). It also provides a transition for internal connections with the shielding structure 30. Because it extends vertically, this structure can adapt to the spatial layout requirements of the connector in the vertical direction. For example, in board-end connectors, it allows for downward grounding, facilitating connection with the motherboard ground layer, while avoiding the space occupation problems caused by horizontal extension. Meanwhile, the shielding structure 30 is provided with a first abutting arm 33 and a second abutting arm 33. These two abutting arms are located on both sides of the terminal group 20 and extend in the vertical direction, corresponding to the wiring portion 225 of the grounding terminals 22 on both sides.

[0064] Reference Figures 1-3 In this embodiment of the present invention, the insulating body 10 includes a base 11 and a tongue plate 12 extending from the base 11 along the first direction, and two sets of terminal groups 20 are respectively arranged on both sides of the tongue plate 12.

[0065] The insulating body 10 serves as the supporting framework of the entire connector, undertaking the core functions of fixing the metal terminals, providing insulation protection, and guiding the mating connection. It is divided into two areas: the base 11 and the tongue plate 12. The base 11, located at the rear, primarily accommodates the soldering or crimping areas of the terminals and connects to external circuitry (such as a PCB). The tongue plate 12, located at the front, is the part inserted into the mating connector and directly participates in the contact conduction process. The tongue plate 12 is a thin, sheet-like insulating structure protruding from the base 11 along a first direction. Its shape can be a flat, elongated strip, with its thickness much smaller than its length and width. This slender, extended design allows it to be smoothly inserted into the cavity of the mating connector, achieving precise mating. More importantly, the upper and lower surfaces of the tongue plate 12 serve as mounting platforms, supporting two sets of terminal groups 20, forming a double-layered conductive array. One set of terminal groups 20 is arranged on the upper surface of the tongue plate 12, and the other set is arranged on the lower surface. The two sets are vertically isolated from each other by the tongue plate 12 as an intermediate medium. This double-sided arrangement greatly increases the number of terminals per unit volume, achieving high-density integration.

[0066] Reference Figures 1-3 In this embodiment of the present invention, the electrical connector further includes a shielding shell 50, which covers the insulating body 10.

[0067] The shielding shell 50 is typically made of a conductive metal material (such as copper alloy, stainless steel, or plated steel), possessing good conductivity and mechanical strength. It completely or partially encloses the insulating body 10 and its internal terminal group 20 from the outside. When the connector is in operation, electromagnetic interference from the external environment (such as radio frequency noise, electrostatic pulses, etc.) is reflected or absorbed by the shielding shell 50 and conducted to the ground wire through a grounding path, preventing it from intruding into the internal circuitry. At the same time, electromagnetic radiation generated by high-speed signals or high-current operation inside the connector is also confined within the shielding shell 50, avoiding interference to the outside world.

[0068] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
