Description

Technical Field

[0001] This utility model relates to an electrical connector. Background Technology

[0002] Traditional electrical connectors typically have only a single power interface, thus limiting their application in high-end, high-reliability equipment. This restricts their ability to support parallel power supply to increase total current, master / slave switching for redundancy, and on-demand configuration to adapt to different power levels. Furthermore, the mixed arrangement of power and signal terminals in traditional connectors means that the strong electromagnetic field generated by high current can severely interfere with the integrity of adjacent high-speed signals, leading to an increased data error rate.

[0003] In view of this, it is necessary to improve the existing electrical connectors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an electrical connector that can achieve flexible configuration of power supply modes.

[0005] To achieve the above-mentioned utility model objectives, this utility model provides an electrical connector, which includes an insulating body and conductive terminals fixed within the insulating body. The insulating body has a power transmission section and a signal transmission section arranged side by side in the transverse direction. The conductive terminals include a plurality of power terminals arranged in the power transmission section and a plurality of signal terminals arranged in the signal transmission section. The power transmission section has at least two first insertion cavities arranged in the height direction, and each first insertion cavity contains two rows of power terminals with contact portions facing each other. The signal transmission section has at least one second insertion cavity, and each second insertion cavity contains two rows of signal terminals with contact portions facing each other. The insulating body also has a notch located on the upper side of the signal transmission section, and the notch is located on the side of the uppermost first insertion cavity in the transverse direction.

[0006] As a further improvement of this utility model, each of the power terminals has a retaining portion fixed in the insulating body, a contact arm extending forward from the retaining portion, and a solder leg bent from the rear end of the retaining portion. The connection portion between the solder leg and the retaining portion of the power terminal located in the uppermost first insertion cavity is exposed outward from the notch in the lateral direction.

[0007] As a further improvement of this utility model, the insulating body also has a mounting post protruding from its lower side for mounting on a circuit board. Each power terminal has a retaining part fixed in the insulating body, a contact arm extending forward from the retaining part, and a solder leg bent from the rear end of the retaining part. The solder legs of the power terminal are arranged in four rows in the front-to-back direction, and the solder legs in the front row are located within the extension range of the mounting post in the front-to-back direction.

[0008] As a further improvement of this utility model, each of the power terminals has a retaining part fixed in the insulating body, at least one pair of contact arms extending forward from the retaining part, and a welding leg bent from the rear end of the retaining part. The power transmission part has a plurality of terminal slots that are formed through it in the front-back direction. Each terminal slot is provided with a partition that partially separates it in the lateral direction. The partition separates two adjacent contact arms of the same power terminal.

[0009] As a further improvement of this utility model, the partition has a receiving groove formed by a recess from back to front, the receiving groove passes through the partition in the lateral direction, and the retaining part is inserted into the corresponding receiving groove.

[0010] As a further improvement of this utility model, the power transmission section also has a plurality of partition walls arranged in the transverse direction and a transverse wall extending in the transverse direction. Each first insertion cavity is provided with a transverse wall corresponding to its rear side. The partition is perpendicularly connected to the transverse wall. The terminal slot is provided with a raised part protruding in the direction of its corresponding transverse wall. The raised part is transversely connected to the partition wall.

[0011] As a further improvement of this utility model, within the same terminal slot, one of the slot walls of the receiving slot, which is away from its corresponding transverse wall in the height direction, is coplanar with the raised portion.

[0012] As a further improvement of this utility model, each of the partition walls is provided with a pair of mating grooves recessed on its lateral sides. The mating grooves on each of the partition walls and the raised portion located on the same side of the partition wall and connected to the partition wall are adjacent to each other to jointly position the corresponding power terminal holding portion.

[0013] As a further improvement of this utility model, the extension length of the raised part in the front-to-back direction is greater than the extension length of the mating groove in the front-to-back direction.

[0014] As a further improvement of this utility model, the power transmission section also has a plurality of protrusions extending from the partition wall toward the rear side. The protrusions are located between the holding portions of two adjacent power terminals in the lateral direction, and their extension dimension in the height direction is greater than the thickness of the holding portion of the power terminal in the height direction.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 7 The present invention is shown as a preferred embodiment of the electrical connector 100, which includes an insulating body 1 and conductive terminals 2 fixed within the insulating body 1.

[0024] The insulating body 1 has a power transmission section 12 and a signal transmission section 13 arranged side by side in the lateral direction. The conductive terminal 2 includes a plurality of power terminals 21 arranged in the power transmission section 12 and a plurality of signal terminals 23 arranged in the signal transmission section 13. The power transmission section 12 has at least two first insertion cavities 120 arranged in the height direction. Each first insertion cavity 120 contains two rows of power terminals 21 with their contact portions facing each other. The signal transmission section 13 has at least one second insertion cavity 130. Each second insertion cavity 130 contains two rows of signal terminals 23 with their contact portions facing each other. The insulating body 1 also has a notch 14 located on the upper side of the signal transmission section 13. The notch 14 is located on the side of the uppermost first insertion cavity 120 in the lateral direction.

[0025] Thus, by setting up multiple independent first plug-in cavities 120, it supports flexible selection of modes that are crucial to high-end equipment, such as parallel current amplification and redundancy backup, thereby improving the system's power limit and reliability. At the same time, by partitioning and paralleling the power terminals 21 and signal terminals 23 and designing a unique missing part 14, it takes into account signal integrity, heat dissipation performance and structural adaptability.

[0026] Specifically, by setting up multiple first plug-in cavities 120, voltages from the same or different power supplies can be connected simultaneously. By using them in parallel, the current carrying capacity can be multiplied to meet the ever-increasing power consumption demands of high-performance computing chips such as CPUs, GPUs, and ASICs, thus solving the heat generation bottleneck problem of power connectors in high-current applications. Furthermore, it can adopt a master-slave switching and redundant backup mode to improve the reliability and availability of the system.

[0027] The notch 14 on the upper side of the signal transmission section 13 provides physical clearance for certain protruding components (such as capacitors and heat sinks) on the mating connector or PCB board, allowing for a more compact device design. At the same time, the notch 14 forms a natural heat dissipation channel, which helps air circulation and removes the concentrated heat generated by the large current in the power terminal area, improving the overall heat dissipation performance. In addition, the asymmetrical structural design can prevent mis-mating, ensuring that the mating connector can only be paired in the correct direction, improving operational reliability.

[0028] Each power terminal 21 has a retaining portion 212 fixed within the insulating body 1, a contact arm 213 extending forward from the retaining portion 212, and a solder leg 214 bent from the rear end of the retaining portion 212. The connection portion 215 of the solder leg 214 and the retaining portion 212 of the power terminal 21, located in the uppermost first insertion cavity 120, is exposed laterally outward from the notch 14. Thus, by exposing the connection portion 215 of the solder leg 214 and the retaining portion 212 laterally outward from the notch 14, heat is dissipated outward through the notch 14, further improving heat dissipation performance.

[0029] In this embodiment, the insulating body 1 further has mounting posts 15 protruding from its lower side for mounting on a circuit board (not shown). The solder feet 214 of the power terminals 21 are arranged in four rows in the front-to-back direction, with the solder feet 214 in the front row located within the extension range of the mounting posts 15 in the front-to-back direction. Thus, by placing the solder feet 214 in the front row within the front-to-back extension range of the mounting posts 15, the stability of the solder feet 214 on the circuit board is enhanced, thereby ensuring the reliability of the electrical connection.

[0030] The power transmission section 12 has a plurality of terminal slots 121 that extend through it in the front-to-back direction. Each terminal slot 121 is provided with a partition 1212 that partially separates it in the lateral direction. The partition 1212 separates two adjacent contact arms 213 of the same power terminal 21.

[0031] In some embodiments, the partition 1212 has a receiving groove 1213 formed recessed from back to front, the receiving groove 1213 passing through the partition 1212 in the lateral direction, and the retaining part 212 is inserted into the corresponding receiving groove 1213. Thus, by inserting the retaining part 212 into the receiving groove 1213 formed on the corresponding partition 1212, the retaining part 212 is limited in the height direction.

[0032] Furthermore, the power transmission unit 12 also has a plurality of partition walls 122 arranged in the transverse direction and a transverse wall 123 extending in the transverse direction. Each of the first insertion cavities 120 is provided with a corresponding transverse wall 123 on its rear side. The partition 1212 is perpendicularly connected to the transverse wall 123. The terminal slot 121 is provided with a raised portion 124 protruding toward the corresponding transverse wall 123. The raised portion 124 is transversely connected to the partition wall 122.

[0033] In addition, in some embodiments, within the same terminal slot 121, the receiving slot 1213 is coplanar with the raised portion 124 on a slot wall surface that is away from its corresponding transverse wall 123 in the height direction.

[0034] Each of the partition walls 122 is provided with a pair of mating grooves 1221 recessed on its lateral sides. The mating grooves 1221 on each of the partition walls 122 and the raised portion 124 located on the same side of the partition wall 122 and connected to the partition wall 122 are adjacent to and jointly position the retaining portion 212 of the corresponding power terminal 21. In this way, the reliability and stability of the positioning of the power terminal 21 are ensured, and the problem of poor electrical connection caused by shaking during long-term use is avoided.

[0035] The extension length of the raised portion 124 in the front-to-back direction is greater than the extension length of the mating groove 1221 in the front-to-back direction. This ensures that the retaining portion 212 can be effectively supported and fixed over a wider range in the front-to-back direction.

[0036] The power transmission section 12 also has a plurality of protrusions 125 extending rearward from the spacer wall 122. Each protrusion 125 is located between the retaining portions 212 of two adjacent power terminals 21 in the lateral direction, and its extension dimension in the height direction is greater than the thickness of the retaining portions 212 of the power terminals 21 in the height direction. This increases the arc creep distance between adjacent power terminals 21.

[0037] The electrical connector 100 of this utility model supports flexible selection of modes crucial to high-end equipment, such as parallel current amplification and redundancy backup, by setting multiple independent first insertion cavities 120, thereby improving the power limit and reliability of the system; at the same time, by partitioning and paralleling the power terminals 21 and signal terminals 23 and designing a unique notch 14, it takes into account signal integrity, heat dissipation performance and structural adaptability.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
