Coupler for cable trough
Couplers for a cable trough system including a terminal end sized to receive a terminal end of a trough member along a longitudinal direction of the body. A spring may be coupled to the body for securing the terminal end of the trough member to the coupler, the spring including first and second spring arms extending generally in opposition to one another in a plane generally parallel to the longitudinal direction. The spring may be received in a slot formed by the trough member. Also included may be a spring release mechanism coupled to the body, the spring release mechanism sliding in the longitudinal direction between a locked position, such that the first and second spring arms engage the terminal end of the trough, and an unlocked position, such that the first and second fingers release the first and second arms of the spring.
1. A cable trough system comprising:
a trough member having a terminal end and including opposing longitudinally-extending first and second sidewalls coupled to a bottom wall generally forming a trough, an exterior surface of the first sidewall of the trough member including opposing longitudinally-extending channel walls projecting outwardly from the exterior surface, extending along a longitudinal direction of the trough member, and defining a slot therebetween, wherein the slot extends from the terminal end to an opposing terminal end of the trough member;
a coupler including a body including a bottom wall and two opposing longitudinally-extending side walls defining a trough, the body having a body terminal end defining an overlap region, the overlap region being sized to slideably receive the terminal end of the trough member along a longitudinal direction of the body; and
a spring comprising at least one resilient spring arm coupled to an outer surface of one of the two side walls of the coupler;
wherein the entirety of the spring is received between the opposing channel walls in the slot when the trough member is inserted into the coupler; and
wherein the spring is biased to resiliently expand in a plane parallel to the first sidewall such that the spring engages at least one of the opposing channel walls within the slot to couple the trough member to the coupler.
2. The system of claim 1 , wherein an exterior surface of the second sidewall of the trough member defines a second slot, and the system further comprises a second spring coupled to the outer surface of the coupler to be received in the second slot.
3. The system of claim 1 , wherein the slot of the trough member is a T-slot.
4. The system of claim 1 , further comprising a spring release mechanism coupled to the coupler body, wherein the spring release mechanism releases engagement of the spring with the trough member when the spring release mechanism is slid in the longitudinal direction of the first sidewall to compress the spring.
