DETAILED DESCRIPTION

Systems and devices for a connector housing with a retention device are described herein. A connector housing can be used to join electrical terminals and create an electrical circuit between cables, devices, and/or combinations thereof.

In some examples, a connector housing can include conductive terminals that can couple wires or cables to a corresponding conductive terminal of the connector housing. As used herein, the term “connector housing” refers to a device that acts as an enclosure for a connection between a wire or cable and a conductive terminal. The connector housing can be an enclosure coupled to an end of a first cable to connect the first cable to a second cable with a corresponding connector housing. For example, the first cable can include a connector housing with a conductive terminal that is a plug. In this example, the second cable can include a connector housing with a conductive terminal that is a jack that can be correspondingly shaped to receive the plug such that the first cable and the second cable can be electrically connected together when the plug and jack are coupled together. A connection between connector housings can be a non-permanent electrical connection. Since the connection is non-permanent, the connection between the connector housings can be disconnected accidently when the connector housings and/or cables are kicked, pulled, and/or extended causing systems attached to the cables to crash, such as when the cables provide power.

In some examples, a server rack can include a plurality of computing devices that each include a plurality of electrical cables and/or communication cables that can utilize different types of connector housings. In some examples, the connector housings of the server rack can be accidently disconnected and cause failures for the computing devices.

In some examples, a retention device can be utilized to provide a relatively stronger connection in order to prevent accidentally disconnecting a connection between connector housings. In some examples, the retention device can be coupled directly to a first connector housing. In these examples, the retention device can extend from the first connector housing to a cable portion coupled to a second connector housing. In some examples, the retention device can be coupled to the cable portion utilizing an aperture that surrounds a portion of the cable. In this way, the retention device can prevent the first connector housing from being removed from the second connector housing, which can prevent a user from accidentally disconnecting the first connector housing from the second connector housing.

FIG. 1 illustrates an example of a retention device 100 according to the disclosure. The retention device 100 can include an extension shaft 103. In some examples, retention device 100 can include a first end 105 and a second end 107. Each end of retention device 100 can be coupled to a connector housing. Retention device 100 can provide high impact strength, making the connector housing to cable connection, cable to cable connection, and/or connector housing to connector housing connection resilient. Retention device 100 can be connected to a first connector housing by coupling one end to the first connector housing.

In some examples, a first end 105 of retention device 100 can be coupled to a first connector housing (not illustrated in FIG. 1). In other examples, a second end 107 of retention device 100 can be coupled to a second connector housing (not illustrated in FIG. 1). The first end of retention device 100 can pivot about a coupling point of the connector housing. Pivoting allows the second end 107 to be attached to a connector housing adding resilience between retention device and connector housing connection. The coupling point of the connector housing can be the point where retention device 100 is attached to and/or molded into the connector housing. In some examples, the coupling point can lock the retention device with the connector housing.

As illustrated in FIG. 1, first end 105 of retention device 100 can be located at an opposite side of second end 107 of the retention device. First end 105 of retention device 100 can include two opposing pins. As used herein, the term “pin” refers to a pointed or penetrating element used to fasten, support or attach things.

In some examples, the opposing pins can interlock the retention device with a housing connector, as described herein. In some examples, the pins can include sharp tips to penetrate the connector housing and fasten the first end 105 with the connector housing. The opposing pins of retention device 100 can engage with apertures molded into a connector housing. In some examples, opposing pins of retention device 100 at first end 105 can be compressible into apertures molded into the connector housing, as illustrated in FIG. 2.

In some examples, first end 105 of retention device 100 can be coupled to a connector housing. A connector housing can connect a first cable at a first side of the connector housing, as described herein. In some examples, one end of the connector housing can be shaped to receive first end 105 of retention device 100. For instance, apertures can be molded into connector housing adjacent to first side 105 of the connector housing. Apertures on first side of the housing connector can be shaped to receive the opposing pins of retention device 100.

As illustrated in FIG. 1, retention device 100 can have a second end 107. Second end 107 can have an aperture. A cable can be inserted into the aperture of the second end 107 and lock retention device 100 to the cable. In some examples, aperture at second 107 can be coupled to a second connector housing (not illustrated in FIG. 1). Second connector housing can have a second cable connected to the second connector housing. Retention device 100 can be coupled to the second connector housing at one end and first connector housing at another end to strengthen the connection between the first and the second connector housing when the two housings are connected to each other.

In some examples, the first connector housing and the second connector housing can connect a first cable and a second cable. In some examples, the first cable and the second cable can include conductive wires that are capable of transmitting electrical power and/or communication signals. In other examples, the first cable can include a protective covering such as a resistive plastic material to protect the conductive wires.

In some examples, retention device 100 can include an extension shaft 103. The extension shaft 103 can alter the length of retention device 100 based on the length of a cable connected to the connector housing. For example, shaft 103 can be elongated if the length of a cable connected to the connector housing has to be extended. In some examples, shaft 103 can be shortened if the length of the cable attached to the connector housing, for example, has to be reduced in length. Extension shaft 103 can be made of thermoplastic and/or metal, among other materials. Extension shaft 103 can include ratchets to extend or shorten the length of the extension shaft 103 based on the length of a cable.

FIG. 2 illustrates an example of a system 200 according to the disclosure. In some examples, system 200 can include a retention device 202, a first connector housing 201, and a second connector housing 211. Retention device 202 can include first end 205 and second end 207. First connector housing 201 can include a first side 201-1, second side 201-2, and can be connected to first cable 209. Second connector housing 211 can be connected to second cable 213. In some examples, the first cable 209 can include conductive wires that are capable of transmitting electrical power and/or communication signals. In some examples, the first cable 209 can include a protective covering such as a resistive plastic material to protect the conductive wires.

The first cable 209 can be coupled to the first connector housing 201. The first connector housing 201 can receive and couple the first cable 209 at a first side 201-1 of the first connector housing 201. In some examples, the first connector housing 201 can include a first conductive terminal that is coupled to a second side 201-2 of the first connector housing 201. The first end of the connector housing 201 and the second end of the connector housing 201 can be at opposite ends of the connector housing 201. In some examples, first connector housing 201 can be coupled to a second connector housing 211.

In some examples, first connector housing 201 can have a second side 201-2, opposite to the side the first conductive terminal is coupled to. The second side 201-2 of the first connector housing 201 can receive and couple a second connector housing 211. In some examples, second connector housing 211 can be removably attached to first connector housing 201. For example, the first connector housing 201 can have an exterior surface, an aperture, an extended portion, a socket, and/or interior groves. The socket and/or interior grooves can be shaped to receive a portion of the second connector housing 211. In some examples, the second connector housing 211 can stay in locked position with the first connector housing 201. The locked position fastens and secures the first connector housing 201 and the second connector housing 211 together, securing the two connector housings. In some examples, second connector housing 211 can be released from the attachable position with first connector housing 201. For example, second connector housing 211, while attached to first connector housing 201, can be pivoted upwards about first end 205 to be released from its attachable position. In some examples, first connector housing 201 and second connector housing 211 can be mounted together.

In some examples, first connector housing 201 can have a first side 201-1 and a second side 201-2. First side 201-1 of connector housing 201 can receive a cable and/or can be connected to another connector housing. Although first connector housing 201 and second connector housing 211 are illustrated in FIG. 2 as being connected to each other, examples of the disclosure are not so limited. For example, multiple connector housings can be connected to each other. For instance, first connector housing 201 can be connected to a third connector housing (e.g., not illustrated in FIG. 2) and/or second connector housing 211 can be connected to a fourth connector housing (e.g., not illustrated in FIG. 2).

In some examples, a first cable 209 can be connected to first side 201-1 of connector housing 201. For example, an aperture can be molded into connector housing 201 adjacent to first side 201-1 where connector housing 201 can receive first cable 209. The cable connecting to first side 201-1 can be determined based on the diameter and shape of the aperture of connector housing 201. Second connector housing 211 can be coupled to the first connector housing.

In some examples, second connector housing 211 can be coupled to second side 201-2 of the first connector housing 201. Second side 201-2 can be on the opposite side of first side 201-1 of first connector housing 201. In some examples, second connector housing 211 can be connected to a second cable 213. Second cable 213 can be coupled to the second connector housing 211 on the opposite side from where second connector housing 211 couples with first connector housing. In some examples, first cable 209 and second cable 213 can be, XLR connectors, 4-pin Mini DIN S-Video cables, power cables, and/or other types of cables.

As described herein, first connector housing 201 can be connected to a second connector housing 211. In some examples, an aperture can be molded into first connector housing 201 adjacent to second side 201-2 where connector housing 201 can be connected to a second connector housing 211. First connector housing 201 and second connector housing 211 can be terminal type electrical connectors that connect wires to a single connection point. Other examples of the connectors can be plug and socket connectors, 8P8C connectors, USB connectors, power connectors, D-subminiature electrical connectors, radio frequency connector and/or DC connectors. In some examples, connector housings 201 and 211 can be crimp on connectors.

In an example in which connector housings 201 and 211 are crimp on connectors, to crimp the connector housings, two pieces of connector housings can be joined together by shaping one or both of the connector housing to hold the other. For example, first connector housing 201 can be shaped to have an extended portion and second connector housing 211 can be shaped to have a socket to crimp the first connector housing to the second connector housing. In other examples, connector housings can be crimped, for example, by shaping second connector housing based on the diameter of the first connector housing. For example, second connector housing can be shaped at ¼ inch of the diameter of first connector housing 201 to fit into the first connector housing. Crimping of the connector housings make connections of the connector housings resilient and prevents them to be disconnected unintentionally.

In some examples, system 200 can include a retention device 202. In some examples, retention device 202 can include a first end 205 and a second end 207. Each end 205 and 207 of retention device 202 can be coupled to a connector housing. Retention device 202 can provide high impact strength, making the connector housing to cable connection, cable to cable connection, and/or connector housing to connector housing connection resilient. Retention device 202 can be connected to a first connector housing 201 by coupling first end 205 to the first connector housing 201 and can be connected to the second connector housing 211 by coupling second end 207 to second cable 213 that is coupled to second connector housing 211, as is further described herein.

The first end 205 of retention device 202 can be coupled to a first connector housing 201. In some examples, first end 205 of retention device 202 can include two opposing pins which can fit into molded apertures of first connector housing 201. In some examples, the pins can include sharp tips to penetrate the connector housing and fasten the first end 205 with the connector housing. In some examples, first connector housing 201 can be shaped to receive the first end of 205 of retention device 202. For example, apertures can be molded into first connector housing 201 to receive opposing pins of retention device 202, as described herein. In some examples, apertures can be molded into connector housing 201 between the first side 201-1 and second side 201-2 of first connector housing 201. Retention device 202 can be locked with the connector housing 201 where the connector housing receives first end 205 of retention device 202. The first end 205 of retention device 202 can pivot about the point where it is coupled to the first connector housing 201.

In some examples, first end 205 of retention device 202 can be located at an opposite side of second end 207 of the retention device. In some examples, retention device 202 can have a second end 207. Second end 207 can have an aperture that can be slid over second cable 213 and lock retention device 202 to cable 213. For example, a second cable 213 can be connected to second connector housing 211. Retention device 202 can be coupled to the second connector housing by inserting aperture 207 to second cable 213.

Retention device 202 can be attached to first connector housing 201 at first end 205. Retention device 202 can be attached to second connector housing 211 at second end 207. Retention device 202 can strengthen the connection between the first and the second connector housing when the two housings are connected to each other.

In some examples, retention device 202 can include an extension shaft 203. The extension shaft can alter the length of retention device 202 based on the length of a cable connected to the connector housing retention device 202. For example, shaft 203 can be elongated if the length of the second cable 213 has to be extended. In some examples, shaft 203 can be shortened if the length of the second cable 213 attached to second connector housing 211 has to be reduced in length. Extension shaft 203 can include ratchets to move the retention device up and/or down in direction based on the length of second cable 213.

In some examples, retention device 202 can be molded into the connector housing 201 that attaches to first cable 209. In one example, retention device 202 can be molded into connector housing 201 using a single injection mold. In some examples, using single injection molding, the connector housing and the retention device can be shaped and customized to affix to each other. In some examples, single injection molding can help with getting more details, for example, getting a rectangularly shaped, a rounded shape and/or other shape connector housing to fit into a corresponding connector housing, as described herein. Molding the retention device and the connector housing can enhance the strength of the attachment point.
