Description

This application claims priority to U.S. Patent Application No. 18/138,167, filed on 24 April 2023. The entire contents of said application are incorporated herein by reference and constitute part of this disclosure. This disclosure relates to connectors, particularly electrical connectors. It is known that electrical connectors with contacts are provided. This disclosure provides further details in light of this background. The purpose of this summary is to facilitate understanding of the disclosure. Therefore, this summary presents the concepts and features of the disclosure in a simplified form and looser terminology than the detailed description below, and should not be construed as limiting other parts of the disclosure. Broadly speaking, this disclosure teaches a connector comprising a contact support and an elastic deformation element, the elastic deformation element exerting a force that biases the contact support in the contact direction defined by the connector when deformed. By using the elastic deformation element to assist in the positioning of the contact support, the connector can accommodate larger misalignments without requiring a large range of motion in the connector contacts themselves. This enables the use of shorter connector contacts and allows for the transmission of higher frequency signals through the connector. Broadly speaking, this disclosure further teaches a connector comprising a housing, a contact support, and an elastic deformation element, the elastic deformation element restraining the movement of the contact support from a position where it intersects a reference plane defined by the housing. By using the elastic deformation element to resist the movement of the contact support from the reference plane, the connector can accommodate larger misalignments without requiring a large range of motion in the connector contacts themselves. This allows for the use of shorter connector contacts and enables the transmission of higher frequency signals through the connector. The disclosure also teaches a plurality of contacts having a pitch of less than 0.35 mm (preferably less than 0.3 mm, most preferably less than 0.25 mm or less than 0.2 mm) and/or a bandwidth per unit volume of more than 2.1 Tbps/ cm³ (preferably more than 2.7 Tbps/ cm³ , most preferably more than 3.2 Tbps/ cm³ or more than 6.4 Tbps/ cm³ ). The pitch should preferably be understood as the pitch between at least two contacts of the plurality of contacts, preferably as the pitch between two adjacent signal contacts (i.e., the signal-to-signal pitch), and most preferably as the pitch between signal contacts of a differential signal pair. However, the pitch between a signal contact and a ground contact (signal-to-ground pitch) or the pitch between any other contacts may also be understood as the pitch. The bandwidth per unit volume mentioned can be further increased, for example, depending on the number of contacts per column or set and per row (as defined below for "column," "set," and "row"). In this explanation, wherever the term "contact" is used, it preferably refers to an electrical contact. The features and advantages mentioned for "connectors," "assemblies," or "assemblies" can also be understood as features and advantages applicable to "structures," and vice versa. "Connectors," "assemblies," or "assemblies" and "structures" can even describe the exact same subject; therefore, the terms "connectors," "assemblies," "assemblies," and "structures" are arbitrarily interchangeable. However, connectors, assemblies, or assemblies can also include structures, and vice versa. A preferred application of the present invention is differential signal transmission. Therefore, it is preferable that at least two of the contacts define at least one differential signal pair. Preferably, the signal transmission according to the present invention can be performed at at least 100 Gbps per differential signal pair, most preferably at at least 200 Gbps. According to the present invention, a high-speed cable assembly (preferably a high-speed copper cable assembly) can be provided. Preferably, the signal transmission according to the present invention can use pulse amplitude modulation (PAM), and can conform to standards such as PAM2 (also known as "non-return-to-zero," NRZ) through PAM4, PAM5, PAM6, PAM7, PAM8, or even PAM16. However, any other modulation or signal transmission technique is also applicable. Preferably, the connector, assembly, bundle, or structure can be used for direct mating on a packaging substrate, such as a printed circuit board, the surface of an integrated circuit die, or the surface of a package substrate. However, the present invention can also be used for any other contact application, particularly planar arrangements on surfaces, preferably without requiring external force (such as a compression plate) for mating the contacts with their respective mating contacts. Most preferably, the present invention
