Description

A server power cord fixing device

technical field

The invention relates to the technical field of server hardware equipment, in particular to a power cord fixing device applied to servers.

Background technique

Servers are large-scale computing equipment used at the company level, and the cable connections are generally long and are generally connected vertically from top to bottom in the computer room. The traditional power cord connection method is that one end of the power cord is connected to the power socket of the server, and the other end of the power cord is directly connected to the socket or copper bar. Because the cables used for servers are usually relatively long, their own weight is very large, while the traditional power cord plugging method is only fixed by the tension force between the power cord socket and the server socket. Therefore, the power cord connected to one end of the server is easy to fall off, causing the server to go down, and there is a risk of data loss.

Detailed ways

For the convenience of description, the coordinate system is now defined as shown in Figure 2.

As shown in FIGS. 1 and 2 , a server power cord fixing device includes a fixing unit 1 and a binding unit 2 .

As shown in Figures 1 and 2, the fixed unit 1 includes a fixed plate 11, the upper side of the fixed plate 11 is provided with a plug connector 12 connected to the chassis body 3 of the server, and the chassis box of the server A round hole for receiving the plug connector 12 is provided on the body 3 at one side of the power socket 4 .

As shown in FIG. 3 , the plug joint 12 includes a vertical plate 121, the left and right sides of the vertical plate 121 are respectively provided with elastic guide plates 122 inclined downwards, and the elastic guide plates 122 are The outer surface (with the side close to the riser 121 as the inner side) and the front and rear sides of the riser 121 jointly form a conical surface with a small diameter at the upper end and a larger diameter at the lower end. Elastic clamping plates 123 are respectively arranged on the lower end surfaces of the elastic guide plates 122 , and the outer surfaces of the elastic clamping plates 123 (with the side close to the vertical plate 121 as the inner side) are circular arc surfaces. The circle defined by the arc surfaces of the two elastic clamping plates 123 is coaxially arranged with the defined conical surfaces of the two elastic guide plates 122, and the arc surfaces of the elastic clamping plates 123 are located The diameter of the circle is smaller than the diameter of the circle where the lower end surface of the elastic guide plate 122 is located. A stepped surface is formed between the elastic guide plate 122 and the elastic clamping plate 123 .

As shown in Figure 9, during installation, the plug connector 12 is inserted into the round hole of the chassis body 3, the elastic guide plates 122 are compressed during the insertion process, and the distance between the two elastic guide plates 122 Decrease until the elastic clamping plate 123 snaps into the circular hole. The freedom of downward movement of the fixing plate 11 is limited by the limited fit between the step surface and the chassis body 3 .

As shown in Figure 9, the left and right ends of the fixing plate 11 are respectively provided with clamping blocks 14 extending obliquely upwards, and the stepped surface is pressed against the chassis body by the clamping blocks 14 3 on the inner side. That is, when the step surface is in contact with the inner surface of the chassis casing 3, the upper end surface of the top tight block 14 is pressed against the outer surface of the chassis casing 3, and the top tight block 14 undergoes a certain elastic deformation.

Preferably, the upper free end of the clamping block 14 is in the shape of a circular arc.

This design mainly serves two purposes. First, to limit the freedom of the fixing plate 11 in the up and down direction, so as to realize the fixing of the fixing unit 1 . Second, in order to facilitate dismounting, when the step surface is in contact with the inner surface of the chassis casing 3, there needs to be a certain distance between the upper side of the fixing plate 11 and the outer surface of the chassis casing 3, so that when When it needs to be disassembled, put your hands between the fixing plate 11 and the chassis body 3, and then pinch the two elastic clamping pieces. By setting the clamping block 14, it is possible to avoid excessive insertion during installation, causing the elastic clamping plate 123 to completely enter the interior of the chassis body 3.

As shown in FIG. 2 , an adjustment belt 13 extending downward is provided on the lower side of the fixing plate 11 , and a binding unit 2 is provided on the adjustment belt 13 .

As shown in Figures 2 and 6, the strapping unit 2 includes a moving plate 21, the rear side of the moving plate 21 is provided with a guide block 22 in the shape of a "door", and the guide block 22 and the moving The plates 21 together form a through hole allowing said adjustment strap 13 to pass through. As shown in Figures 7 and 8, a first elastic plate 221 is arranged inside the guide block 22, the upper end of the first elastic plate 221 is fixedly connected with the web of the guide block 22, and the first elastic The lower end of the plate 221 protrudes from the lower side of the guide block 22 , for convenience of description, the part of the first elastic plate 221 protruding from the lower side of the guide block 22 is defined as a first pressing plate. A side of the adjusting belt 13 facing the guide block 22 is provided with a plurality of first locking teeth 131 , and the plurality of first locking teeth 131 are evenly distributed along the vertical direction. The structure of the first locking tooth 131 is the same as that of the ratchet in the ratchet structure, and will not be repeated here. A positioning block 222 matched with the first engaging teeth 131 is disposed on the front side of the first elastic plate 221 .

As shown in Figure 2, the front side of the moving plate 21 is provided with an arc-shaped strap 23, and one end of the strap 23 is fixedly connected to the moving plate 21, the strap 23 The other end is suspended, and the outer surface of the suspended end of the strap 23 is provided with a plurality of second engaging teeth 231, and the second engaging teeth 231 have the same structure as the ratchet teeth in the ratchet structure, and are not repeated here. repeat. As shown in FIG. 4 , an insertion hole 211 for allowing the strap 23 to be inserted is provided on the moving plate 21 at a position corresponding to the free end of the strap 23 . The moving plate 21 is located on the outside of the jack 211 (with the side away from the fixed end of the strap 23 as the outside) to be provided with a second elastic plate 212, and the suspended end of the second elastic plate 212 is provided with a The positioning plate 213 matched with the above-mentioned second locking tooth 231 , and the outer end of the positioning plate 213 (the end far away from the binding strap 23 is the outer end) protrudes from the outside of the second elastic plate 212 . For the convenience of description, the part of the positioning plate 213 located outside the second elastic plate 212 is now defined as a second pressing plate.

For the convenience of operation, as shown in FIG. 5 , an adjustment push plate 232 is provided on the outer surface of the strap 23 .

Since the strap 23 itself has a certain degree of softness, when the positioning plate 213 is matched with the second engagement teeth 231, the strap 23 is pressed by the positioning plate 213, and it is easy to adapt to the inside. Deformation, which will cause the clamping is not firm. For this reason, as shown in FIG. 4 , the moving plate 21 is located on the inner side of the insertion hole 211 (with the side away from the fixed end of the strap 23 as the outer side) to be provided with an abutment that matches the positioning plate 213 . The leaning plate 214 prevents the binding belt 23 from being adaptively deformed under the action of the positioning plate 213 .

During use, first insert the plug connector 12 into the round hole of the chassis body 3, then pass the plug of the power cord through the strap 23, and connect it to the power socket 4 on the chassis. Then adjust the position of the strapping unit 2 on the adjustment belt 13 according to the actual situation (when moving the strapping unit 2 upwards, it is not necessary to press the first pressing plate; 2 will do). Then the hanging end of the strap 23 is inserted into the jack 211, and the power cord is locked (when the power cord is locked, the second pressing plate is not needed, and when the strap 23 needs to be loosened, press the second pressing plate. Two press the plate, then outwardly twitch the strap 23 to get final product).
