[0011] In the following description, reference is made to the accompanying figures that form a part thereof and in which various embodiments are shown by way of illustration. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.
[0012] In the following disclosure, the following definitions are adopted.
[0013] As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably.
[0014] As used herein as a modifier to a property or attribute, the term “generally,” unless otherwise specifically defined, means that the property or attribute would be readily recognizable by a person of ordinary skill but without requiring absolute precision or a perfect match (e.g., within + / - 20 % for quantifiable properties).
[0015] The term “substantially,” unless otherwise specifically defined, means to a high degree of approximation (e.g., within + / - 10% for quantifiable properties) but again without requiring absolute precision or a perfect match.
[0016] As used herein, all numbers should be considered modified by the term “about.” The term “about,” unless otherwise specifically defined, means to a high degree of approximation (e.g., within + / - 5% for quantifiable properties) but again without requiring absolute precision or a perfect match.
[0017] As used herein, the terms “first” and “second” are used as identifiers. Therefore, such terms should not be construed as limiting of this disclosure. The terms “first” and “second” when used in conjunction with a feature or an element can be interchanged throughout the embodiments of this disclosure.
[0018] As used herein, when a first material is termed as “similar” to a second material, at least 90 weight % of the first and second materials are identical and any variation between the first and second materials comprises less than about 10 weight % of each of the first and second materials.
[0019] As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B.”
[0020] As used herein, the term “between about,” unless otherwise specifically defined, generally refers to an inclusive or a closed range. For example, if a parameter X is between about A and B, then A < X < B.
[0021] An electrical connector assembly is generally used to connect a cable or a cable assembly from one device (e.g., a server, a network switching system, a client device, etc.) to another device (e.g., another server) for various applications, such as data processing, data transmission, and data reception.
[0022] However, different combinations of different configurations of connectors may be required in different applications. Therefore, there may exist a need for a modular electrical connector assembly.
[0023] The present disclosure relates to an electrical connector assembly. The electrical connector assembly includes a plurality of connectors. The plurality of connectors is configured to simultaneously mate with a plurality of corresponding mating portions of a same mating connector along a same mating direction and arranged side-by-side along a lateral direction substantially orthogonal to the mating direction to form a row of the connectors. Each of the connectors includes a housing. The housing includes a mating end for mating with a corresponding mating portion of the mating connector along the mating direction and an opposite cable end for receiving an electric cable. Each of the connectors further includes a circuit board at least partially disposed in the housing. The circuit board includes a plurality of conductive front pads disposed proximate the mating end of the housing, and a plurality of conductive rear pads disposed between the front pads and the cable end of the housing. The rear pads are electrically connected to the front pads. Each of the connectors further includes the electric cable at least partially disposed in the cable end of the housing and terminated at the rear pads. The housing of each of the connectors further includes opposing top and bottom channels formed in respective top and bottom major surfaces of the housing. The top and bottom channels extend along the lateral direction. The top and bottom channels are aligned so as to form opposing substantially aligned respective continuous top and continuous bottom channels of the row of the connectors. For at least one pair of laterally adjacent connectors in the plurality of connectors, the connectors include engaging features that engage each other to prevent the adjacent connectors from sliding relative to each other along the mating direction. The electrical connector assembly further includes a bracket removably assembled to the row of the connectors. The bracket includes opposing top and bottom portions disposed in the respective continuous top and bottom channels of the row of the connectors. Thebracket further includes opposing side portions disposed in side channels formed in opposing respective sides of opposing endmost connectors in the row of the connectors.
[0024] Therefore, the electrical connector assembly of the present disclosure may have a modular design which may enable combining different connectors into multiple configurations for different applications. Specifically, desired connectors may be selected and assembled via the substantially aligned respective continuous top and continuous bottom channels, the engaging features, and the bracket removably assembled to the selected connectors. The engaging features may engage the adjacent connectors to prevent the adjacent connectors from sliding relative to each other. The engaging features may also facilitate alignment of the row of the connectors.
[0025] Further, the electrical connector assembly may reduce a need for manufacturing different electrical connector assemblies for different applications. Further, the electrical connector assembly may reduce a need for replacement of a combined connector assembly specifically manufactured for an application. This may also minimize the repair and maintenance cost. Furthermore, the electrical connector assembly may also enable standalone use of the connectors in various applications, i.e., different connectors of the electrical connector assembly may be individually used or used in different combinations, as per desired application attributes.
