Connection device of cable management arm

摘要

A connection device of a cable management arm (10) includes a fixing frame (16) having a protrusion portion (26), a connection member (18) having a contact portion (32), and a locking member (20) pivotably connected to the connection member (18). The locking member (20) includes a locking portion (40) and a resilient portion (42) which contacts the contact portion (32) of the connection member (18). When the connection member (18) is pivotally connected to the cable management arm (10), the fixing frame (16) is fixed to a rail. When the connection member (18) is connected to the fixing frame (16), the resilient portion (42) provides a force to lock the locking portion (40) to the protrusion portion (26) of the fixing frame (16) so as to securely connect the connection member (18) to the fixing frame (16).
