Coupler for cable trough

A coupler for a cable trough system, the coupler comprising:

• a body including walls defining a bottom wall and two side walls defining a trough, the body having a body terminal end defining an overlap region extending toward a mid-point of the body, the overlap region being sized to slideably receive a terminal end of a trough member along a longitudinal direction of the body;
• and
• a locking element coupled to the body and including a main body, a spring, and a spring release mechanism, the spring including first and second spring arms with free ends aligned in a plane extending in a direction non-transverse with respect to an adjacent one of the bottom wall or two side walls, wherein the first and second spring are are located to engage the terminal end of the trough member in the overlap region, and the spring release mechanism including first and second fingers configured to slide in the longitudinal direction along the main body of the locking element between a locked position, wherein the first and second spring arms engage the terminal end of the trough member, and an unlocked position, wherein the first and second fingers disengage the first and second spring arms from the terminal end of the trough member, and the main body including a T-shaped detent positioned to engage an edge of the spring release mechanism to hold the spring release mechanism in the unlocked position.

A coupler for a cable trough system including a trough member having a terminal end, the coupler comprising:

• a body having an open end and including first and second guiding surfaces defining a spacing, the spacing being sized to receive the terminal end, with the first guiding surface slideably engageable with an internal wall surface of the terminal end and with the second guiding surface slideably engageable with an external wall surface of the terminal end;
• the spring including first and second spring anus aligued in a plane generally parallel to the first and second guiding surfaces;
• and
• the spring release mechanism including a spring release, wherein, when the terminal end of the trough member is inserted into the coupler body, the first and second spring arms engage opposing portions of the trough member defining a slot, and wherein the spring release releases the first and second arms from engagement with the opposing portions when the spring release is slid along the main body of the locking element in a direction parallel to the first and second guiding surfaces, and the main body including a T-shaped detent positioned to engage an edge of the spring release mechanism to hold the spring release mechanism in engagement with the first and second arms of the spring.

A coupler for a cable trough system, the coupler comprising:

• a spring including first and second spring arms extending at an angle with respect to one another;
• and
• a locking element coupled to the body and including a main body with a railway on which a spring release mechanism slides, the locking element including an unlocked position, in which the spring release mechanism is held by a T-shaped detent of the main body of the locking element in engagement with the spring, and a locked position, in which the spring release mechanism slides along the railway of the main body of the locking element in the longitudinal direction to release the spring.
