The present invention relates to the connections of terminals and, in particular, to creating a mechanism to quickly disconnect a set of terminal.
Many forms of communication transmission and power transmission require physical lines that connect a source terminal to a destination terminal. These physical lines are generally buried in the ground or placed above ground level. In many situations, there is no easy way to access or repair the physical line in the event that the physical line is damaged.
In some applications, such as fiber optics, a stable connection needs to be maintained between terminals. This connection requires that the terminals be properly aligned and held steady during operation. These connections are susceptible to damage caused by sudden motion.
Sudden motion may damage the physical line by pulling, tearing, or breaking the physical line. An example of sudden motion includes a traffic accident that causes the physical line to be dragged from a first location to a second location by a vehicle. In such a case, the physical line may need to be re-laid from the source to the destination. This process is time consuming, labor intensive, and expensive. In order to avoid the damage caused by sudden motion to a physical line, a quick release cable system is needed.
In one embodiment, a method is disclosed that involves creating a connection between two different terminals in a connecter, wherein the first terminal and second terminal are aligned. This method also includes creating a potential energy source that acts on at least one of the two terminals. In this embodiment, an inhibiting force controls the potential energy source. Also in this method, a triggering the potential energy source to separate the first and second terminal by removing the inhibiting force, wherein the potential energy released is sufficient to eject the first terminal from the connecter.
In another embodiment, a system is shown that includes a connector comprising an alignment chamber; a first terminal coupled to a first cable positioned in the alignment chamber, and a second terminal coupled to a second cable positioned in the alignment chamber. The second terminal interface is perpendicular to the alignment chamber and placed where the second terminal interface is facing the first terminal interface. In addition, this system includes an ejection mechanism coupled to the first interface that is positioned to force the first terminal outside of the alignment chamber and an inhibitor that stops the ejection mechanism. A trigger is coupled to the ejection mechanism and removes the inhibitor thereby activating the ejection mechanism.
In yet another embodiment, a fiber optic connection apparatus is disclosed that includes an alignment chamber. In the alignment chamber is a first fiber optic terminal and a second fiber optic terminal coupled to the first fiber optic terminal. In addition, a securing mechanism is placed within the alignment chamber and forces the first fiber optic terminal and second fiber optic terminal together. Also in this embodiment an ejection mechanism is disclosed that ejects the first fiber optic terminal upon the removal of the securing mechanism.
For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, wherein like numbers designate like objects, and in which:
It may be advantageous to set forth definitions of certain words and phrases that may be used throughout this patent document: the terms “include” and “comprise,” as well as derivatives thereof, mean inclusion without limitation; the term “or,” is inclusive, meaning and/or; the phrases “associated with” and “associated therewith,” as well as derivatives thereof, may mean to include, be included within, interconnect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interleave, juxtapose, be proximate to, be bound to or with, have, have a property of, or the like; and the term “controller” means any device, system or part thereof that controls at least one operation, such a device may be implemented in hardware, firmware or software, or some combination of at least two of the same. It should be noted that the functionality associated with any particular controller might be centralized or distributed, whether locally or remotely.
Physical cables may be used to transmit both power and information. These physical cables are generally made up of a plurality of segments connected together through junctions. In many applications, such as fiber optics, at junctions where a first terminal is connected to a second terminal, a rigid connection is required. The advantage of a rigid connection is that it promotes the connection between the first terminal and the second terminal with transmission mediums such as light, waves, or power. The disadvantage of such a connection is that any force applied to the connection may result in damage to the physical cable connected by the junction. In order to avoid damage caused by forces applied to the junction, a quick release mechanism is needed that provides the advantages of a physical connection between the first and second terminal while allowing for a quick release of the first terminal from the second terminal in the event of a force being applied to the junction.
An embodiment 100 of a quick release mechanism is depicted in
In the example shown in
It is, therefore, contemplated that the present disclosure may use three forces. The first force is a potential force created by the compression of the spring 106. The second force is an inhibiting force created by the use of triggering mechanisms 108 and 110. The third force is an ejection force created by the release of the potential force. These forces may be orientated in any way known to one skilled in the art. For instance, in some embodiments, the inhibiting force may be a represented by a vector that is substantially perpendicular to the potential force. The present disclosure is intended to contemplate any quick release mechanism for disconnecting a first terminal from a second terminal that uses a combination of the disclosed potential, inhibiting, and ejection forces when used in the connection of the first terminal 102 to the second terminal 104.
First terminal 102 and second terminal 104 are used to connect a first cable to a second cable. It is contemplated that first terminal 102 and second terminal 104 may be used to connect any kind of cable including, but not limited to, fiber optical cables, communication cables, or power transmission cables. The first terminal 102 and the second terminal 104 may comprise a plurality of alignment pins, wherein the alignment pins allow a single connection alignment of the first terminal 102 and the second terminal 104. It is contemplated that the first terminal 102 and the second terminal 104 may promote an interface between a plurality of fiber optic connections in a single fiber optical cable.
In
Once the potential energy is released from the spring 106, the spring 106 will eject the first terminal 102 from the connector 112. This ejection may prevent damage to the cables 302 and 304, as prior to the cables being pulled, the connection between the first cable 302 and 304 is released. This quick release mechanism will prevent damage to the cables as has been previously discussed.
Although the present invention and its advantages have been described in the foregoing detailed description and illustrated in the accompanying drawings, it will be understood by those skilled in the art that the invention is not limited to the embodiment(s) disclosed but is capable of numerous rearrangements, substitutions and modifications without departing from the spirit and scope of the invention as defined by the appended claims.
