Definitions

  • Mechanical connectors are often used to connect a conductive wire to devices.
  • a conductive wire carrying direct current (DC) power can be connected to a power supply unit using a mechanical connector.
  • mechanical connectors e.g., friction fit and compression style mechanical connectors
  • a mechanical connector implementation may be dictated by specific needs of certain industries. For example, the
  • telecommunications industry may require a particular type of connector that may be different conventional connector styles.
  • FIG. 1 is a perspective view of an example power supply unit (PSU) including a lug connector;
  • PSU power supply unit
  • FIGS. 2A-2B are perspective views an example lug connector with terminal lugs on the same side of the connector.
  • FIGS. 3A-3B are perspective views of an example lug connector with terminal lugs on opposite sides of the connector.
  • Mechanical connectors can be used to attach direct current (DC) power to a device such as a power supply unit (PSU).
  • Connectors can be designed in different styles that may be dictated by the specific needs of a customer (e.g., companies of a specific industry). For example, a telecommunications customer may reject a friction fit and compression style mechanical connector and prefer a terminal block style connector with lugs. This requirement may necessitate a redesign of the PSU to allow for installation of the terminal block, which could add significant costs. Moreover, as PSUs have become significantly smaller, there may not be enough real estate on the PSU to allow for installation of the terminal blocks.
  • Examples described herein address the above challenges by providing a lug connector that can be adapted for use with existing connectors and devices (e.g., PSUs).
  • the examples describe a terminal block style lug connector that provides a power connection solution that meets telecommunication customer needs, without redesigning the PSU.
  • the described examples provide a positive retention mechanism to secure the lug connector to a corresponding female connector of the PSU, as required.
  • a connector for a power supply unit includes a first terminal lug to couple a first power conductor to the connector and a second terminal lug to couple a second power conductor to the connector.
  • the connector includes a retention mechanism to secure the connector to a corresponding female connector of the PSU.
  • a power supply unit includes a male connector.
  • the male connector includes a terminal portion that includes a first lug and a second lug to attach power conductors.
  • the male connector includes a mating portion to couple with a female connector of the PSU.
  • the male connector also includes a positive retention mechanism to secure the mating portion of the male connector to the female connector.
  • a device in another example, includes a female connector and a male connector.
  • the male connector includes a terminal portion that includes a first terminal lug and a second terminal lug to attach to power conductors, and a mating portion to couple with the female connector.
  • the device also includes a positive retention mechanism to secure the male connector to the female connector.
  • FIG. 1 is a perspective view of an example power supply unit (PSU) including a lug connector.
  • PSU 100 can supply direct current (DC) power to other computing devices.
  • PSU 100 can be installed in a rack to supply power to computing devices such as servers, networking devices, storage devices, etc.
  • PSU 100 can be an inserted component of such computing devices to the devices.
  • PSU 100 can be inserted into a slot of a server device to supply DC power to the server device. The insertion can be via blind mate connection, where the PSU 100 can be slid or snapped into the server without the use of tools.
  • PSU 100 can covert mains alternating current (AC) to low-voltage regulated DC power for the devices.
  • AC mains alternating current
  • PSU 100 can be a hot-plug PSU unit meaning that PSU 100 can be replaced (i.e., inserted or removed) from a system (e.g., a server system) without shutting down the system or significant interruption to the operation of the system.
  • PSU 100 can include a chassis or enclosure 110 to house the various components of the PSU 100 (e.g., fan and other electrical components).
  • the enclosure 110 of the PSU 100 can further include other components like a handle 114 to facilitate insertion or removal of the PSU 100 from a system, and a latching mechanism 114 to secure the PSU 100 to the system when inserted.
  • PSU 100 also includes a female connector 120 and a male connector 130.
  • the female connector 120 is a part of the PSU 100 (i.e., housed within the enclosure 110 of the PSU 100) and the male connector 130 can be removably coupled to the female connector 120.
  • the female connector 120 and the male connector 130 form a single unit of the PSU 100.
  • the male connector 130 can be secured to the female connector 120 via a positive retention mechanism 140. Although the positive retention mechanism 140 is shown as screw in FIG.
  • the positive retention mechanism 140 could be a latch, a notch, a flange, or any other mechanism to firmly secure the male connector 130 to the female connector 120 such that the male connector 130 does not move, wiggle, vibrate, or otherwise loosen, or such that the male connector 130 cannot be removed from the female connector 120 without causing substantial damage (i.e., visible damage) to the PSU 100 or to the male connector 130.
  • retention mechanism 140 can be made of non-conductive materials.
  • Male connector 130 can include a mating portion (not shown) to couple with the female portion 120 in the PSU 100, and a terminal portion 132.
  • Terminal portion 132 includes a first terminal lug 134a and a second terminal lug 134b (collectively referred to as terminal lug 134).
  • Terminal lugs 134 are used to attach power conductors 136a and 136b (collectively referred to as terminal conductors 136).
  • Terminal lugs 134 are secured onto the terminal portion 132 of the male connector 130 using screws 138a and 138b (collectively referred to as screws 138).
  • power conductors 136 can include a return (i.e., ground/earthed) cable and -48V power DC power cable.
  • Connector 130 is described in greater details with reference to FIGS. 2A-2B and 3A-3B.
  • FIGS. 2A-2B are perspective views an example lug connector with terminal lugs on the same side of the connector.
  • FIG. 2A shows a top view of the connector 130 while FIG. 2B shows a bottom view of the connector 130.
  • the terminal lugs 134 will be secured/located on the same side of the connector 130 (i.e., on a top surface of the connector 130).
  • the terminal lugs 134 can be secured to the top surface of the connector 130 using screws 138.
  • Connector 130 includes a terminal portion 132 and a mating portion 220.
  • Mating portion 220 can be a two-prong structure projecting away from the terminal portion 132 for mating with a corresponding female connector 120 of the PSU 100.
  • Mating portion 220 can enclose electrically conducting materials (e.g., metals) housed within the connector 130, and can be made of non-conducting materials (e.g., plastic).
  • Mating portion 220 can include through holes 222a and 222b (collectively referred to as holes 222) through which corresponding electrically conducting materials from the female connector 120 of the PSU 100 can make electrical contact with the conducting materials of the mating portion 220 when connector 130 is coupled to female connector 120.
  • Holes 222 can be of any shape and size (e.g., round, cylindrical, square, triangular, etc.) to permit electrical coupling of the conductive materials of the connector 130 and the female connector 120 of the PSU 100.
  • a positive retention mechanism 140 can be used to secure the connector 130 to the female connector 120.
  • positive retention mechanism 140 can be a screw, a latch, a flange, or any other positive retention mechanism to firmly secure the connector 130 to the female connector 120 such that the connector 130 may not move, wiggle, vibrate, or otherwise loosen away from the female connector 120.

  • positive retention mechanism 140 can be formed of non-conductive material.
  • FIGS. 3A-3B are perspective views of an example lug connector with terminal lugs on opposite sides of the connector.
  • FIG. 3A shows a top view of the connector 130 while FIG. 3B shows a bottom view of the connector 130.

  • another terminal lug 134a will be secured on the bottom surface of the connector 130 via the screw 138a. It may be beneficial to have the terminal lugs 134 located on opposite sides or surfaces of the connector 130 to enhance cable management and/or to further reduce the risk of accidental removal of the power cables and/or connector 130 from the PSU 100.
