Description

POWER CORD RETENTION ASSEMBLY
BACKGROUND
[0001] A power source, such as a power distribution unit (PDU) or a power extension bar may provide power to a computing device such as a server computer that is coupled to the power source. A power cord of the computing device may be plugged into a receptacle of the power source so that power can be provided to the computing device.
BRIEF DESCRIPTION OF THE DRAWINGS
[0002] Some examples of the present application are described with respect to the following figures:
[0003] FIG. 1 illustrates an example of a power cord retention assembly; and
[0004] FIG. 2 illustrates another example of a power cord retention assembly.
DETAILED DESCRIPTION
[0005] As described above, a power cord of a computing device such as a server computer, a laptop computer, a tablet computer, a smartphone, a networking device, a storage device, etc. can be plugged into a receptacle of a power supply/source (e.g., a PDU or an extension bar) to provide power to the computing device. For a computing device that is powered by electricity up to 250 volts, a plurality of power cords compliant with the International Electrotechnical Commission (IEC) 60320 standard may be used to provide power to the computing device via corresponding receptacles. For example, under the IEC 60320 standard, a C14 power cord may be used to provide power to a computing device via a C13 receptacle. As another example, a C20 power cord may be used to provide power to a computing device via a CI 9 receptacle. [0006] When a power cord, such as a C 14 power plug, is plugged into to a receptacle, such as a CI 3 receptacle, electricity may flow from a power source to a computing device. However, the power cord may be unplugged from the receptacle inadvertently. For example, the power cord may be unplugged from the receptacle due to loose coupling between the power cord and the receptacle. As another example, the power cord may be unplugged from the receptacle due to external interference, such as when a person runs into the power cord and/or the receptacle thereby uncoupling the power cord from the receptacle. When the power cord is inadvertently unplugged from the receptacle, the computing device may shut down due to loss of power and unsaved data on the computing device may be lost.
[0007] Accordingly, examples described herein address the above challenges of a power cord inadvertently unplugged from a receptacle of a power source by providing a power cord retention assembly to retain (or lock) multiple types of power cords within a receptacle of a power source. For example, a power cord retention assembly may include a receptacle including a plurality of notches to receive a power cord and a retention base. The receptacle may receive a first type of power cord via the retention base, where the retention base includes locking features to couple to the notches of the receptacle, and a retention clip to secure the power cord to the receptacle via the retention base. The receptacle may also receive a second type of power cord that includes a locking feature, where the locking feature of the second type of power cord is to couple to a notch on a bottom side of the receptacle. In this manner, examples described herein may significantly reduce a likelihood of a power cord inadvertently unplugging from a receptacle such as due to an external force or due to loose coupling of the power cord and the receptacle. In addition, one receptacle may be used to achieve better retention of the power cord within the receptacle for multiple different types of power cords.
[0008] In one example, a power cord assembly includes a receptacle including a plurality of notches to receive a power cord and a retention base. The retention base includes locking features to couple to the notches of the receptacle. The power cord retention assembly also includes a retention clip to secure the power cord to the receptacle via the retention base.
[0009] In another example, a power cord retention assembly includes a receptacle including notches on opposite sides of the receptacle and on a bottom side of the receptacle. The receptacle is to receive a first type of power cord via a retention base, where the retention base includes locking features to couple to the notches on opposite sides of the receptacle, and where the retention base includes a retention clip to secure the first type of power cord to the receptacle via the retention base. The receptacle is also to receive a second type of power cord via a locking feature of the second type of power cord, where the locking feature of the second type of power cord is to couple to the notch on the bottom side of the receptacle.
[0010] Referring now to the figures, FIG. 1 illustrates an example of a power cord retention assembly. Power cord retention assembly 100 includes a receptacle 120. Receptacle 120 can be any type of inlet receptacle that is used to couple to a corresponding power cord, such as power cord 130. For example, receptacle 120 may be an inlet receptacle that is compliant with the International Electrotechnical Commission (IEC) 60320 standard, such as a C 13 receptacle, a CI 5 receptacle, a C17 receptacle, a CI 9 receptacle, a C21 receptacle, or the like. Receptacle 120 can include a plurality of notches 122. Notches 122 can be located on either sides of the receptacle 120 and at a bottom side of the receptacle 120. For example, a notch 122 can be located on a left side, on a right side, and on the bottom side of the receptacle 120. Notches 122 can be in the form of a hole, a slot, or an indent on the receptacle 120 for locking with a corresponding locking feature/mechanism.
[0011] The assembly 100 also includes a retention base 140. Retention base 140 can include locking features 142 to couple to the notches of the receptacle 120. For example, locking features 142 can mate with the notches 122 of the receptacle 120 when the retention base 140 is inserted into the receptacle 120. Locking features 142 may be any design features used to increase an amount of force needed to remove the retention base (including the power cord 130) from the receptacle 120. For example, locking features 142 may be a retaining tab extending from a body portion 144 of the retention base 140. Locking features 142 can be located on opposite sides of the body portion 144 of the retention base 140.
[0012] The body portion 144 of the retention base 140 is configured to receive the portion of the power cord 130 that is insertable into the receptacle 120 (i.e., the plug portion of the power cord 130). Thus, the plug of the power cord 130 can sit on the body portion 144 of the retention base and both can be inserted into the receptacle 120, whereby the locking features 142 of the retention base 140 can be coupled to the notches 122 of the receptacle 120.
[0013] When the power cord 130 and the retention base 140 are inserted together into the receptacle, retention clip 150 can be used to secure the power cord 130 to the receptacle 120. To secure and retain the power cord 130 in the receptacle 120, the retention clip 150 is attached to the power cord 130 and adjusted till it reaches the base of the plug portion of the power cord 130 (i.e., the over-mold of the plug).
Retention clip 150 locks onto grooves on an elongated portion 146 of the retention base 140 to secure the power cord 130. To remove or disengage the power cord 130 from the receptacle 120, the retention clip 150 can be squeezed to enable the retention base to be released from the notches 122 of the receptacle 120 and enable removal of the power cord 130.
[0014] In some examples, the receptacle 120 can receive a second type of power cord having a different configuration from the power cord 120. For example, the second type of power cord can include a locking feature to couple to a notch 122 of the receptacle 120 when the second type of power cord is inserted into the receptacle 120. In such an example, the second type of power cord can be inserted into the receptacle 120 without the retention base 140 and the retention clip 150. The locking feature of the second type of power cord can be located, for example, at a bottom (or base) of the plug portion of the second type of power cord such that when the second type of power cord is inserted into the receptacle 120, the locking feature engages with the bottom notch 122 of the receptacle to increase an amount of force needed to remove the second type of power cord from the receptacle. Such a locking feature of the second type of power cord may be a retaining tab extending or protruding from a base or bottom portion of the plug of the second type of power cord. It should be noted that receptacle 120 may include additional notches 122 such as another notch on a top portion or side of the receptacle 120 to engage with other types of power cords that may have locking features on a top portion of the plug.
[0015] FIG. 2 illustrates another example of a power cord retention assembly. The power cord retention assembly 100 shows the power cord 120 and the retention base 140 inserted in the receptacle 120. In the example of FIG. 2, the locking features 142 of the retention base are engaged with the notches 122 of the receptacle. Further, retention clip 150 is engaged to secure the power cord 130 in the receptacle to prevent accidental removal of the power cord 130 from the receptacle 120. To remove the power cord 130 (and the retention base 140) from the receptacle, the retention clip can be squeezed to release or disengage the locking features 142 of the retention base from the notches of the receptacle 120. The example of FIG. 2 also shows a notch 122 on a base of the receptacle for use with a second type of power cord that includes locking features that can engage with the notch 122.
