Publication number: 20240162663Abstract: A connector for use with high-speed signals. The connector has a housing, which includes conductive elements held in a row by a housing. Each conductive element includes a thinner portion and a thicker portion. The conductive elements are configured to make contact with a mating component at the thicker portions. The thinner portions are closer to mating ends of respective conductive elements than respective thicker portions. The housing is configured to provide voids selectively disposed underneath the conductive elements. Such a configuration increases impedances for the conductive elements at locations that would otherwise have lower impedance and therefore reduces impedance variations along signal transmission paths. Such a configuration can also reduce stub size and therefore reduce insertion loss. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.Type: ApplicationFiled: November 14, 2023Publication date: May 16, 2024Applicant: Amphenol Commercial Products (Chengdu) Co., Ltd.Inventors: Kui Yang, Xiaodong Hu, Yaohua Hou, Lei Liao

Patent number: 11942716Abstract: A configurable electrical connector. The electrical connector includes conductors held by a housing. Contact tails of the conductors extend from a mounting face of the housing therethrough. The mounting face of the housing includes a slot. In some embodiments, the slot exposes portions of ground conductors of the connector and receives a member coupled with the exposed portions of the ground conductors such that the electrical connector can meet high performance requirements. The member may be inserted into or molded in the slot. In some embodiments, the slot may or may not receive a member that is insulative when the electrical connector does not need to meet the high performance requirements. Such a configuration enables the same connector to be compatible with multiple performance protocols.Type: GrantFiled: September 16, 2021Date of Patent: March 26, 2024Assignee: Amphenol Commercial Products (Chengdu) Co., Ltd.Inventors: Bing Liu, Yaohua Hou, Tao Zeng

Publication number: 20240079825Abstract: Connectors for use with high-speed signals. Mating connectors may include interlocking components that control the mated position of the connectors such that wipe distance can be reduced. These components may be compact such that they can be integrated into connectors with standardized exterior dimensions. They may be integrated into mating guides of the mating connectors. For one of the mating connectors, such a component may be a locking member disposed in and curving out of its guide such that the locking member mates with a matching feature of a component in the guide of the other connector. As the connectors are secured by these components, the conductive elements may be shorter than the lengths required by standards, which reduces the stub and therefore increases signal integrity. Such a configuration provides higher signal integrity at higher speeds, while conforming to standards that constrain mating and mounting interfaces.Type: ApplicationFiled: August 31, 2023Publication date: March 7, 2024Applicant: Amphenol Commercial Products (Chengdu) Co., Ltd.Inventors: Kui Yang, Xiaodong Hu, Yaohua Hou

Publication number: 20240072494Abstract: A connector for use with high-speed signals. The connector includes a connector subassembly having conductors disposed in groups and a shielding shell at least partially encircling each group. Each conductor includes a mating end and a mounting end opposite the mating end. The shielding shell includes openings that expose contact surfaces of the conductors at the ends. The shielding shell is formed by attaching a second shell part to a first shell part. The first shell part has plateaus and valleys, and the second shell part is attached to the first shell part at the valleys, such that tubular structures are formed. The shielding shell includes contact surfaces disposed on the same planes with the contact surfaces of the conductors at the ends, respectively. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.Type: ApplicationFiled: July 19, 2023Publication date: February 29, 2024Applicant: Amphenol Commercial Products (Chengdu) Co., Ltd.Inventors: Rui He, Xiaodong Hu, Yaohua Hou, Lei Liao

Publication number: 20230335931Abstract: Card edge connectors that are reliable and robust against impacts by external forces while having narrower widths by industry standards. A connector includes a housing having a body with a slot elongated longitudinally. The housing has a pair of towers extending vertically from opposite ends of the longitudinal slot. Each tower has a slot elongated vertically, and is narrower than the body in a transverse direction. The longitudinal slot and the vertical slots are configured to receive edges of an electronic card. The connector has a pair of reinforcing members. Each reinforcing member is at least partially disposed on a tower and configured to support a joint between the tower and the body of the housing. Such a configuration can increase robustness of the connector at the joints and therefore reduce the risks of deforming or cracking the towers when the connector is impacted by an external force.Type: ApplicationFiled: April 12, 2023Publication date: October 19, 2023Applicant: Amphenol Commercial Products (Chengdu) Co., Ltd.Inventors: Rui He, Xiaodong Hu, Kui Yang, Yaohua Hou
