The present disclosure relates generally to a connector and a connector assembly, and in particular, to a connector and a connector assembly for mating with a mating connector.
A connector assembly is generally used to connect a cable 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.
In one aspect, the present disclosure provides a connector assembly configured to mate with a mating connector along a mating direction. The connector assembly includes a circuit board including a plurality of conductive front pads disposed on opposing major upper surfaces and lower surfaces of the circuit board at a mating end thereof. The circuit board further includes a plurality of conductive rear pads disposed on at least one of the major upper and lower surfaces of the circuit board at a cable end thereof opposite to the mating end. The rear pads are electrically connected to the front pads. The connector assembly further includes at least one cable including a plurality of conductors, front ends of which terminate at the rear pads. The connector assembly further includes an insulative housing tightly overmolded around at least the cable end of the circuit board, the front ends of the conductors, and the rear pads. The mating end of the circuit board extends forwardly from a mating face of the housing along the mating direction and is configured to be inserted into a front opening of the mating connector. The connector assembly further includes an electrically conductive unitary shield including a top wall extending between back and front ends thereof. The shield further includes a front wall extending downwardly from the front end of the top wall and opposing side walls extending downwardly from opposite side edges of the top wall. The shield is rotatably attached to the housing near the back end of the top wall and is configured to rotate about a laterally oriented first axis that passes through the housing behind the circuit board, between an open position and a closed position. The connector assembly further includes a pull tab rotatably attached to the shield near the front end of the top wall and configured to rotate about a laterally oriented second axis substantially parallel to the first axis. The connector assembly is configured to mate with the mating connector when the shield is in the open position. When the connector assembly is fully mated with the mating connector, the shield is configured to rotate from the open position to the closed position. The rotation of the shield from the open position to the closed position results in the top wall covering and shielding the housing, the circuit board, and the mating connector. The rotation of the shield from the open position to the closed position further results in the front wall being disposed at, and covering and shielding at least a portion of, a back side of the mating connector. The rotation of the shield from the open position to the closed position further results in the opposing side walls being disposed at, and covering and shielding at least portions of, opposing sides of the mating connector. The rotation of the shield from the open position to the closed position further results in a retention feature of the shield engaging a corresponding retention feature of the mating connector to prevent the connector assembly from unmating from the mating connector.
In another aspect, the present disclosure provides a connector configured to mate with a mating connector along a mating direction. The mating connector includes a mating insulative housing including a mating side defining a front opening therein. The mating insulative housing further includes an opposite back side, and opposing lateral sides extending between and connecting the mating and back sides. The connector includes a circuit board including a plurality of conductive pads. The connector further includes an insulative housing tightly overmolded around at least a portion of the circuit board. A mating end of the circuit board extends forwardly from a mating face of the housing along the mating direction and configured to be inserted into the front opening of the mating side of the mating insulative housing. The connector further includes an electrically conductive unitary shield including opposing side wings rotatably attached to corresponding lateral sides and near a rear face, opposite the mating face, of the housing. The shield is configured to rotate about a laterally oriented first axis that passes through the side wings between an open position and a closed position. Upon a full mating between the connector and the mating connector, the shield is configured to rotate from the open position to the closed position so that the shield covers substantially entire top and lateral sides, and at least a portion of the back side, of the mating insulative housing, and opposing retention features of the shield engage corresponding retention features of the mating connector on opposite lateral sides of the mating connector to prevent the connector from unmating from the mating connector.
Exemplary embodiments disclosed herein may be more completely understood in consideration of the following detailed description in connection with the following figures. The figures are not necessarily drawn to scale. Like numerals used in the figures refer to like components. When pluralities of similar elements are present, a single reference numeral may be assigned to each plurality of similar elements with a small letter designation referring to specific elements. When referring to the elements collectively or to a non-specific one or more of the elements, the small letter designation may be eliminated. However, it will be understood that the use of a numeral to refer to a component in a given figure is not intended to limit the component in another figure labeled with the same number.
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.
In the following disclosure, the following definitions are adopted.
As recited herein, all numbers should be considered modified by the term “about”. As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably.
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).
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.
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.
Terms such as same, equal, uniform, constant, strictly, and the like, are understood to be within the usual tolerances or measuring error applicable to the particular circumstance rather than requiring absolute precision or a perfect match.
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.
As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B”.
Expansion of data processing and data storage requirements typically causes an increasing demand for facilities (e.g., server rooms) to accommodate growing numbers of servers and supporting equipment. This demand may lead to an emphasis on physical space conservation in the facilities to accommodate more servers and supportive equipment. One or more connector assembly components typically need to conform to applicable industry standards. Further, in some cases, a heat sink may be disposed near conventional connector assemblies. Generally, conventional connector assemblies cannot be arranged below the heat sink which limits utilization of available space. Current or conventional connector assemblies may not support high-speed data processing and data storage functions as required by next generation database servers.
The present disclosure provides a connector assembly configured to mate with a mating connector along a mating direction. The connector assembly includes a circuit board including a plurality of conductive front pads disposed on opposing major upper surfaces and lower surfaces of the circuit board at a mating end thereof. The circuit board further includes a plurality of conductive rear pads disposed on at least one of the major upper and lower surfaces of the circuit board at a cable end thereof opposite to the mating end. The rear pads are electrically connected to the front pads. The connector assembly further includes at least one cable including a plurality of conductors, front ends of which terminate at the rear pads. The connector assembly further includes an insulative housing tightly overmolded around at least the cable end of the circuit board, the front ends of the conductors, and the rear pads. The mating end of the circuit board extends forwardly from a mating face of the housing along the mating direction and is configured to be inserted into a front opening of the mating connector. The connector assembly further includes an electrically conductive unitary shield including a top wall extending between back and front ends thereof. The shield further includes a front wall extending downwardly from the front end of the top wall and opposing side walls extending downwardly from opposite side edges of the top wall. The shield is rotatably attached to the housing near the back end of the top wall and is configured to rotate about a laterally oriented first axis that passes through the housing behind the circuit board, between an open position and a closed position. The connector assembly further includes a pull tab rotatably attached to the shield near the front end of the top wall and configured to rotate about a laterally oriented second axis substantially parallel to the first axis. The connector assembly is configured to mate with the mating connector when the shield is in the open position. When the connector assembly is fully mated with the mating connector, the shield is configured to rotate from the open position to the closed position. The rotation of the shield from the open position to the closed position results in the top wall covering and shielding the insulative housing, the circuit board, and the mating connector. The rotation of the shield from the open position to the closed position further results in the front wall being disposed at, and covering and shielding at least a portion of, a back side of the mating connector. The rotation of the shield from the open position to the closed position further results in the opposing side walls being disposed at, and covering and shielding at least portions of, the opposing sides of the mating connector. The rotation of the shield from the open position to the closed position further results in a retention feature of the shield engaging a corresponding retention feature of the mating connector to prevent the connector assembly from unmating from the mating connector.
The connector assembly of the present disclosure may have a low profile. Implying that the connector assembly of the present disclosure possesses a reduced thickness, breadth/width, length, surface area, and/or potential volume than those of conventional connector assemblies. For example, an integration of the housing and the shield in the connector assembly may result in the low profile of the connector assembly. Therefore, the connector assembly may require less physical space than conventional connector assemblies. Further, the connector assembly may be accommodated in available space that is/was not utilized in conventional connector assemblies, such as below heat sinks. In some cases, the mating connector may be mounted on a circuit board, within the available space between a heat sink and the circuit board. The connector assembly may further allow easy connection of the at least one cable with a mating connector associated with a device or a server (e.g., 1U rack server, blade server, GPU server, etc.). Further, the mating connection between the connector assembly and the mating connector may provide electromagnetic shielding from external devices.
Moreover, the connector assembly of the present disclosure may prevent accidental disconnection of the mating connector. An undesirable relative movement between the connector assembly and the mating connector in the fully mated state may also be prevented to ensure seamless connectivity between the connector assembly and the mating connector. The connector assembly may also be easily mated with the mating connector.

In some embodiments, the housing 30 further includes a stop portion 35 to limit a maximum rotation of the shield 40 from the closed position 40b to the open position 40a to less than about 60 degrees. In some embodiments, the stop portion 35 limits the maximum rotation of the shield 40 from the closed position 40b to the open position 40a to less than about 55 degrees, less than about 50 degrees, or less than about 45 degrees. In some embodiments, the stop portion 35 may include one or more inclined surfaces. In some other embodiments, the stop portion 35 may be curved. The maximum rotation of the shield 40 from the closed position 40b to the open position 40a may depend upon a geometry of the stop portion 35, such as an angle of inclination of the stop portion 35. In the illustrated embodiment of the
In some embodiments, the housing 30 further includes one or more protrusions 56. The shield 40 may engage with the one or more protrusions 56 to rotatably attach with the housing 30. In some cases, the housing 30 includes pair of protrusions 56. Each protrusion 56 may engage with a corresponding opening 54 of the shield 40 to rotatably attach the housing 30 to the shield 40. Specifically, each protrusion 56 may be at least partially received within the corresponding opening 54 to form the rotatable attachment 47 between the shield 40 and the housing 30. In some embodiments, the protrusions 56 are formed on the respective lateral sides 33 of the housing 30. In other words, each lateral side 33 of the housing 30 includes one protrusion 56.

Referring to
The rotation of the shield 40 from the open position 40a to the closed position 40b results in the top wall 41 covering and shielding the housing 30, the circuit board 10, and the mating connector 300. The rotation of the shield 40 from the open position 40a to the closed position 40b further results in the front wall 44 being disposed at, and covering and shielding at least a portion of, the back side 320 of the mating connector 300. The rotation of the shield 40 from the open position 40a to the closed position 40b further results in the opposing side walls 45 being disposed at, and covering and shielding at least portions of, the opposing sides 315 of the mating connector 300. Specifically, the shield 40 is configured to rotate from the open position 40a to the closed position 40b so that the shield 40 covers substantially the entire top and lateral sides 350, 315, and at least a portion of the back side 320 of the mating insulative housing 355.
The rotation of the shield 40 from the open position 40a to the closed position 40b further results in the retention feature 48 of the shield 40 engaging the corresponding retention feature 340 of the mating connector 300 to prevent the connector assembly 200 from unmating from the mating connector 300. Specifically, the opposing retention features 48 of the shield 40 engage the corresponding retention features 340 of the mating connector 300 on the opposite lateral sides 330 of the mating connector 300 to prevent the connector 200 from unmating from the mating connector 300. The opposing retention features 48 of the shield 40 may removably engage the corresponding retention features 340 to facilitate mating and unmating of the connector assembly 200 and the mating connector 300. This may allow servicing and/or replacement of one or more components of the connector assembly 200.
Furthermore, when the connector assembly 200 is fully mated with the mating connector 300, the engagement of the retention feature 48 of the shield 40 with the retention feature 340 of the mating connector 300 prevents the two connectors 200, 300 from moving relative to each other along the mating direction. Therefore, the engagement of the retention feature 48 of the shield 40 with the retention feature 340 of the mating connector 300 may prevent accidental unmating of the mating connection.
The engagement between the retention feature 48 of the shield 40 and the corresponding retention feature 340 prevents the connector assembly 200 from unmating from the mating connector 300. The engagement between the retention feature 48 of the shield 40 and the corresponding retention feature 340 may further prevent the two connectors 200, 300 from moving relative to each other along the mating direction. This may further prevent an undesirable relative movement between the connector assembly 200 and the mating connector 300 in the fully mated state and may ensure seamless connectivity between the connector assembly 200 and the mating connector 300.
