Description

Adjustable air stop and assembly with same

Technical Field

The present invention relates to a cable management mechanism in an electronic chassis (electronic chassis), and more particularly, to an adjustable air block (adjustable air block) for laying cables in an electronic chassis.

Background

Advances in 5G technology have led to the growth of networks that require interconnection equipment with electronics enclosures to house the cabling. Such an electronic chassis includes electronic components connected to other electronic components, such as a 5G Central Unit (CU), a Distributed Unit (DU), a Remote Radio Unit (RRU), an Active Antenna Unit (AAU), and a Radio Unit (RU), by cables. These cables may have different sizes and different lengths. Without the organized alignment and placement of these cables, clusters (clusters) may form within the electronics chassis as the cables pass through the various electronic components within the electronics chassis, thereby becoming unmanageable. Therefore, there is a need for an in-situ component in an electronic chassis for managing and routing cables connecting different electronic components in the electronic chassis.

FIG. 1A is a perspective view of an adjustable air block 100 mounted on an assembly plate 130 of an electronic chassis. FIG. 1B is an exploded view of the adjustable air block 100 shown in FIG. 1A. Referring to FIG. 1A, an adjustable air block 100 is shown mounted on an assembly plate 130. A plurality of cables 105 are routed through the adjustable air block 100 and arranged in a linear fashion to connect different electronic components. As previously discussed, the adjustable air block 100 is an existing in-situ component on the assembly panel 130 of an electronics chassis that is used to block and redirect airflow in a designated area of the electronics chassis. As shown in fig. 1B, the adjustable air stop 100 includes a housing 150, a first inner plate 140a and a second inner plate 140B. The case 150, the first inner plate 140a, and the second inner plate 140b may be formed of a thermal insulating material. The heat insulating material may be, for example (but not limited to) a plasticized material.

The housing 150 includes a hollow cubic block 170 having a top end 172 and a bottom end 174. The hollow cube 170 also includes a central gate 175 extending between the top end 172 and the bottom end 174. The central gate 175 has a left side edge 176 and a right side edge 178. Although the hollow cube 170 is rectangular in shape in the illustrated embodiment, it is contemplated that in other embodiments, the hollow cube 17 may be spherical, pyramidal, or cylindrical with any polygonal shaped bottom surface. In the present embodiment, the hollow cubic block 170 has a rectangular parallelepiped shape.

The hollow cube 170 includes a left plate 190a and a right plate 190b at the top end 172. The left plate 190a forms an upper surface 192a with grooves (grooved) at the top end 172 of the hollow cubic block 170 to the left of the central gate 175. The left plate 190a has an opening 193a (shown in fig. 3) located on the upper surface 192a, a lower surface 194A (shown in fig. 4A), and a first longitudinal opening 195a located between the upper surface 192a and the lower surface 194A. The left plate 190a further includes a first knob protrusion 198a passing through a leftmost end 196a of the first longitudinal opening 195a and having a knob 199a (shown in fig. 4A).

The top end 172 of the hollow cubic block 170 to the right of the central gate 175 is formed with a grooved upper surface 192b by the right plate 190 b. The right plate 190b has an opening 193b located on the upper surface 192b, a lower surface 194b (as shown in fig. 4A), and a second longitudinal opening 195b located between the upper surface 192b and the lower surface 194 b. The right plate 190b further includes a second knob protrusion 198b passing through a rightmost end 197b of the second longitudinal opening 195b and having a knob 199b (shown in fig. 4A).

In some embodiments, the housing 150 further includes a flat plate 180 connected to the hollow cube 170 at the bottom end 174. The flat plate 180 forms a raised rim (flanged rim)185 around the hollow cube 170. The four corners of the plate 180 each include an opening 182 for allowing the housing 150 to be mounted to the assembly plate 130. In some embodiments, the hollow cubic blocks 170 and the flat plates 180 may be distinct components, while in other embodiments, the hollow cubic blocks 170 and the flat plates 180 may form a single piece (single piece).

The first inner plate 140a is fixed to the top end 172 of the hollow cube 170 by the screw 110 a; and the screw 110a is fixed to the hollow cubic block 170 by the nut 120 a. The first inner plate 140a has a first vertical portion 142a and a first horizontal portion 145 a. The first vertical portion 142a has a first inner surface 141a and a first outer surface 143 a. Wherein the first inner surface 141a is configured to abut the left edge 176 of the central gate 175 when assembled. The first vertical portion 142a is adjustably connected to the left side edge 176 along the first inner surface 141a by a first mechanical spring 160a, as described in detail below. The first outer surface 143a of the first vertical portion 142a has a first flexible buffer layer 144a attached thereto. In some embodiments, the first flexible buffer layer 144a may be made of an elastic material. The elastic material may be, for example, but not limited to, sponge (sponge), foam (foam), or the like.

In assembly, the first horizontal portion 145a of the first inner plate 140a is formed above the first vertical portion 142a to form an L-shaped bracket (L-shaped cradle) extending to the left side at the top end 172 of the hollow cubic block 170. Thus, when the first inner plate 140a is connected to the left side edge 176 of the central gate 175, the first horizontal portion 145a is configured to extend leftward along the top end 172 of the hollow cubic block 170. The first horizontal portion 145a has a first bottom surface 146a (as shown in fig. 2A), and the first bottom surface 146a includes a third knob protrusion 148a with a knob 149a (as shown in fig. 4A). The first horizontal portion 145a further includes one or more apertures 147a for receiving the screws 110a and nuts 120a for connecting the first inner plate 140a to the hollow cube 170. Although the first horizontal portion 145a includes two apertures 147a in the illustrated embodiment, it is contemplated that the first horizontal portion 145a may have a greater or lesser number of apertures 147 a.

The second inner plate 140b is fixed to the top end 172 of the hollow cube 170 by the screw 110 b; and the screw 110b is fixed to the hollow cubic block 170 by the nut 120 b. The second inner plate 140b has a second vertical portion 142b and a second horizontal portion 145 b. The second vertical portion 142b has a second inner surface 141b and a second outer surface 143 b. Wherein the second inner surface 141b is configured to abut the right side edge 178 of the central gate 175 when assembled. The second vertical portion 142b is adjustably connected to the right side edge 178 along the second inner surface 141b by a second mechanical spring 160b, as described in detail below. The second outer surface 143b of the second vertical portion 142a has a second flexible buffer layer 144b attached thereto. In some embodiments, the second flexible buffer layer 144b can be made of an elastic material. The elastic material may be, for example, but not limited to, sponge (sponge), foam (foam), or the like.

In assembly, the second horizontal portion 145b of the second inner plate 140b is formed above the second vertical portion 142b to form an L-shaped bracket extending to the right at the top end 172 of the hollow cubic block 170. Thus, when the second inner plate 140b is connected to the right side edge 178 of the central gate 175, the second horizontal portion 145b is configured to extend rightward along the top end 172 of the hollow cube 170. The second horizontal portion 145b has a second bottom surface 146b (as shown in fig. 3), and the second bottom surface 146b includes a fourth knob protrusion 148b having a knob 149b (as shown in fig. 4A). The second horizontal portion 145b further includes one or more openings 147b for receiving the screw 110b and the nut 120b for connecting the second inner plate 140b to the hollow cubic block 170. Although the second horizontal portion 145b includes two apertures 147b in the illustrated embodiment, it is contemplated that the second horizontal portion 145b may have a greater or lesser number of apertures 147 b.

The third knob protrusion 148a in the first horizontal portion 145a of the first inner plate 140a is insertably inserted through the first longitudinal opening 195a of the left plate 190a of the hollow cubic block 170. This may allow the third knob protrusion 148a to be aligned in height with the first knob protrusion 198a on the left plate 190a when assembled so that the knobs 149a and 199a may face each other. The first mechanical spring 160a is then adjustably disposed in the first longitudinal opening 195a between the knob 199a of the first knob protrusion 198a and the knob 149a of the third knob protrusion 148 a.

Similarly, the fourth knob protrusion 148b in the second horizontal portion 145b of the second inner plate 140b is insertably inserted through the second longitudinal opening 195b of the right plate 190b of the hollow cube 170. This may allow the fourth knob protrusion 148b to be aligned in height with the second knob protrusion 198b on the right plate 190b when assembled so that the knobs 149b and 199b may face each other. Thereafter, a second mechanical spring 160b is adjustably disposed in the second longitudinal opening 195b and between the knob 199b of the second knob protrusion 198b and the knob 149b of the fourth knob protrusion 148.

The first mechanical spring 160a is fixedly attached within the first longitudinal opening 195a such that the first inner plate 140a is adjustably connected to the left edge 176 of the central gate 175 of the hollow cube 170. Similarly, a second mechanical spring 160b is fixedly attached within the second longitudinal opening 195b such that the second inner plate 140b is adjustably connected to the right edge 178 of the central gate 175 of the hollow cube 170. Thus, the compression or relaxation of the first and second mechanical springs 160a and 160b, respectively, enables the first and second inner plates 140a and 140b to move away from or approach each other.

Fig. 2A, 2B, 3, 4A, 4B and 5 illustrate the steps of assembling the adjustable air stop 100. Fig. 2A-2B are perspective views illustrating a process of assembling the first inner plate 140a and the flexible buffer layer 144a to form the adjustable air block 100. The first flexible buffer layer 144a may be attached (attached) to the first inner panel 140a by applying a pressure P to the first outer surface 143a of the first vertical portion 142a of the first inner panel 140 a. When attached, a top surface of the first flexible buffer layer 144a is flush with a first bottom surface 146a of the first horizontal portion 145a of the first inner plate 140 a. Although not shown in fig. 2A through 2B, the second inner panel 140B may also be assembled with the second flexible buffer layer 144B in a similar manner.

Fig. 3 is a perspective view showing a structure of connecting the first and second inner plates 140a and 140b to the hollow cubic block 170. The first and second inner plates 140a and 140b are aligned such that the first and second flexibility bumpers 144a and 144b face each other. The first and second inner plates 140a and 140b are then placed into the central gate 175. When placed, the first inner surface 141a of the first vertical portion 142a of the first inner plate 140a is aligned with the left side edge 176 of the central gate 175, and the first bottom surface 146a of the first horizontal portion 145a is placed on the upper surface 192a of the left plate 190a of the hollow cubic block 170. Similarly, when placed, the second inner surface 141b of the second vertical portion 142b of the second inner plate 140b is aligned with the right edge 178 of the central gate 175, and the second bottom surface 146b of the second horizontal portion 145b is placed on the upper surface 192b of the right plate 190b of the hollow cubic block 170.

The first inner plate 140a is then bonded to the hollow cubic block 170 by passing the screws 110a through the holes 147a in the first horizontal portion 145a of the first inner plate 140a and through the holes 193a in the upper surface 192a of the left plate 190a on the hollow cubic block 170. Similarly, the second inner plate 140b is coupled to the hollow cube 170 by passing the screws 110b through the holes 147b in the second horizontal portion 145b of the second inner plate 140b and through the holes 193b in the upper surface 192b of the right plate 190 b.

Fig. 4A to 4B respectively show a bottom perspective view and a bottom view of a cut-away structure in which the first mechanical spring 160a and the second mechanical spring 160B are provided in the hollow cubic block 170. As previously described, the first mechanical spring 160a is adjustably disposed in the first longitudinal opening 195a and between the knob 199a of the first knob protrusion 198a and the knob 149a of the third knob protrusion 148 a. Similarly, a second mechanical spring 160b is adjustably disposed in the second longitudinal opening 195b between the knob 199b in the second knob protrusion 195b and the knob 149b of the fourth knob protrusion 148 b. Thereby forming the adjustable air stop 100. The compression and relaxation of the first mechanical spring 160a within the first longitudinal opening 195a and the second mechanical spring 160b within the second longitudinal opening 195b enables the first and second inner plates 140a and 140b, respectively, to move away from or approach each other. Thus, the central gate 175 of the hollow cube 170 is adjustably opened and closed to accommodate a plurality of electrical cables 105 having different sizes and lengths.

FIG. 5 is a perspective view of the adjustable air block 100 mounted to the assembly plate 130. Screws 184 are inserted through openings 182 in raised rim 185 of plate 180. Screws 184 are secured through the bottom surface of plate 180 by nuts 186, thereby attaching adjustable air block 100 to assembly plate 130.

FIGS. 6A-6B show bottom perspective and bottom views, respectively, of the structure of the adjustable air block 100 before cables 105 have been routed through it. By applying the stress Q at the intersection of the first horizontal portion 145a of the first inner plate 140a and the second horizontal portion 145b of the second inner plate 140b, the electric cable 105 can be pressed down for routing. The application of the stress Q will separate the first and second horizontal portions 145a, 145b and slightly open the central gate 175 of the hollow cube 170 between the first and second compliant buffers 144a, 144 b. Further application of stress Q will spread the first and second flexible buffer layers 144a, 144b apart.

FIGS. 7A-7B show bottom perspective and bottom views, respectively, of the cable routing through the adjustable air block. The two oppositely directed horizontal components + M and-M of the stress Q will sufficiently distract the first and second flexible bumpers 144a, 144b such that the first and second vertical portions 142a, 142b of the first and second inner plates 140a, 140b will also move in opposite directions along the plane of the flat plate 180. As a result, the first mechanical spring 160a is compressed inside the first longitudinal opening 195a and the second mechanical spring 160b is compressed inside the second longitudinal opening 195b, thereby accommodating the electrical cable 105 between the first and second flexible buffer layers 144a and 144 b. Once the cable 105 is inserted, the stress Q is removed, causing the first and second mechanical springs 160a and 160b to again relax, thereby closing the central gate 175. The adjustable air stops 100 function as air stops. Thus, a plurality of cables 105 can be accommodated in the adjustable air block 100.

As described herein, the adjustable air stops reduce the use of cable clamps (cable clips) and provide flexible space for accommodating and routing cables of different sizes without any openings in the structure. This design allows the adjustable air stops to continue to block airflow and redirect airflow to other designated areas of the electronics chassis. The cable can be installed without threading and will be automatically clamped by the adjustable air stop after the cable is laid. This helps to optimize the number of mechanical structures in the electronics chassis.
