The first structure 60b and the second structure 65b are a combination of a protrusion and a recess (hole), but the implementation is not limited thereto. Here, the first structure 60b is taken as a protruding hook, and the second structure 65a is taken as a hole.

The operating member 62 is operatively connected to the latch member 60, and the operating member 62 has an operating portion 63 disposed adjacent to the second portion 54b of the connecting device 54. Preferably, the operating portion 63 extends a distance beyond the second portion 54b of the connecting device 54 in a direction away from the first portion 54a of the connecting device 54 (e.g., the second direction D2). Preferably, the connecting device 54 is arranged on the at least one support 48 by a base 66. The base 66 includes a base portion 66a and a wall portion 66 b. The base portion 66a is connected to an end 48a adjacent to the at least one support member 48, and the wall portion 66b is disposed upright relative to the base portion 66 a. The connecting means 54 is arranged at the wall portion 66 b. For example, the connecting device 54 is pivotally connected to the wall portion 66b via a first shaft 68.

Wherein, the axle center of the first axle element 68 passes through a part of the first longitudinal long hole 72a and is pivoted with the first seat part 64a of the mounting seat 64; on the other hand, the axis of a second shaft 74 passes through a part of the second longitudinal long hole 72b and connects with the second seat 64b of the mounting seat 64. Preferably, one of the operating element 62 and the latch element 60 has a guiding structure, and here, the operating element 62 and the latch element 60 respectively have a first guiding structure 76 and a second guiding structure 78 that are matched with each other, and the first guiding structure 76 and the second guiding structure 78 are inclined planes or arc surfaces, for example.

As shown in fig. 8 and 9, the carrier 38 is folded into the rack 22 relative to the first rail 30 by the second rails 32 of the first rail assembly 28a and the second rail assembly 28 b. Wherein a space S between the connection device 54 and the first wall 24 of the rack 22 is generally limited (or constricted); alternatively, sometimes the space S may be obstructed by other related members 80 due to different requirements; alternatively, as shown in fig. 2, sometimes a rack system is arranged with a plurality of sets of rail assemblies from top to bottom, and these rail assemblies usually have a predetermined specification height therebetween, so that the specification height also forms a spatial limitation to some extent. However, the operation of the connecting device 54 of the present embodiment is not affected in these situations.

Further, when the first portion 54a (e.g., the front portion) of the connecting device 54 is connected to the connecting section 65 of the first rail 30 of the second slide rail assembly 28b, if the at least one supporting member 48 is to be detached from the connecting section 65 of the first rail 30 of the second slide rail assembly 28b, the user can operate the first portion 54a to detach from the connecting section 65 of the first rail 30 of the second slide rail assembly 28b from the position of the second portion 54b (e.g., the rear portion) of the connecting device 54.

As shown in fig. 9, the first portion 54a of the connecting device 54 can be clamped to the second structure 65a of the connecting section 65 of the first rail 30 of the second slide rail assembly 28b by the first structure 60b of the clamping member 60; on the other hand, the operating member 62 is in a first predetermined position P1 relative to the mounting seat 64. As shown in fig. 10 and 11, a user can apply a force F to the operating portion 63 to longitudinally displace the operating member 62 relative to the mounting seat 64 from the first predetermined position P1 (fig. 9) to a second predetermined position P2 (fig. 11), so that the latch 60 generates a force by the first guide structure 76 contacting the second guide structure 78, and the first structure 60b of the latch 60 can be released from the second structure 65a of the connecting section 65 of the first rail 30 of the second rail assembly 28b by the elastic portion 60 a.

It can be seen that the connection device 54 of the present embodiment provides a user to operate the first portion 54a (e.g., the front portion) from the position of the second portion 54b (e.g., the rear portion). Thus, the coupling device 54 can provide for a user to manipulate the first portion 54a from a position of the second portion 54b (e.g., the rear portion) to detach from a target object (e.g., the first rail 30 of the second slide assembly 28 b). Alternatively, when the cable management assembly 40 is applied to the frame 22, a user standing behind the frame 22 may manipulate the first portion 54a (e.g., the front portion) to be detached from the first rail 30 of the second slide rail assembly 28b directly from the position of the second portion 54b (e.g., the rear portion).

Fig. 12 shows another embodiment of the connecting device 54 according to the present embodiment. Specifically, unlike the first embodiment in which the connecting device 54 is disposed on at least one support 48, this embodiment of the connecting device 54 is applied to the wire management arm 200 (e.g., the first wire management arm or the second wire management arm). Specifically, the attachment device 54 may replace the mounting member (e.g., the first mounting member 56 or the second mounting member 58). Therefore, the wire management arm 200 can be connected to the object (e.g., a slide rail) through the connecting device 54. According to this arrangement, the coupling device 54 also provides for a user to manipulate the first portion 54a (e.g., the front portion) from the position of the second portion 54b (e.g., the rear portion) to detach from a target object (e.g., the first rail 30 of the first track assembly 28a) when the wire organizing arm 200 is to be detached from the target object (e.g., a track).

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

(1) a user may be provided to manipulate the first portion 54a from a position at the second portion 54b (e.g., the rear) of the attachment device 54.

(2) Unlike the prior art shown in fig. 1 in which the user's hand is inconveniently pressed from the side of the connecting mechanism 114 due to the limited or narrow space D, the connecting device 54 of this embodiment can provide the user to operate the first portion 54a from the position of the second portion 54b (e.g., the rear portion) to detach the object (e.g., the first rail 30 of the slide rail assembly) from the object.

(3) When the cable management assembly is applied to the rack 22, a user standing behind the rack 22 may manipulate the first portion 54a of the connection device 54 to detach from an object directly from the location of the second portion 54b (e.g., the rear portion) of the connection device 54 in the event that some space of the rack 22 is restricted or too constricted.

Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
