Description

Cable auxiliary installation fixture

The present invention relates to a mounting fixture, and more particularly to a fixture for assisting the installation of wires.

Generally speaking, there is usually an independent open space reserved inside the server so that the cables can be installed directly from top to bottom. However, as the available space inside the chassis has become smaller and smaller in recent years, when there is insufficient space, the cables can only be installed using the odd-shaped spaces between components. This also requires that a simple component be disassembled into several parts, or that the component be forcibly moved during assembly to form a temporary opening due to temporary deformation, so that the cables can be placed in this opening and installed inside the server.

Please refer to the first and second figures. The first figure is a three-dimensional schematic diagram showing a server casing of the prior art; the second figure is an enlarged schematic diagram of circle A in the first figure.

As shown in the first and second figures, the existing server case PA100 is mainly provided with a clip plate PA2 on the side panel PA1, and the clip plate PA2 is mainly fixed to the bottom of the side panel PA1 or the bottom plate PA3 of the server case PA100 in a unilateral fixing manner. Thus, when the user wants to install the wire, the wire can be placed between the clip plate PA2 and the side panel PA1 by pulling the clip plate PA2.

As mentioned above, although the way of pulling the clamping plate PA2 can temporarily form an opening between the clamping plate PA2 and the side plate PA1, in actual production line assembly, in order to avoid the opening being too small and causing the wire to be scratched and damaged by the clamping plate PA2 or the side plate PA1 when inserted, the operator usually maintains the opening at a size that is significantly larger than the wire. The clamping plate PA2 is movable, so it is easy to cause plastic deformation of the clamping plate PA2 due to excessive pulling force. At this time, even if the operator releases the clamping plate PA2, the clamping plate PA2 cannot elastically return to its original position due to the plastic deformation, resulting in the wires arranged between the clamping plate PA2 and the side plate PA1 cannot be fixed by the clamping plate PA2 and the side plate PA1.

In view of the fact that in the prior art, although the existing server case can fix the wires to the side panels inside the server case by setting a clamp, the clamp can easily exceed the elastic deformation range due to excessive pulling, causing the clamp to undergo plastic deformation and be unable to elastically return to its original position; therefore, the main purpose of the present invention is to provide a wire auxiliary installation fixture that allows the clamp to only deform moderately to allow the wires to enter between the clamp and the side panel.

The present invention solves the problems of the prior art by adopting a necessary technical means of providing a wire auxiliary installation fixture, which is used to install a wire between a side plate and a clamping plate close to the side plate, and the clamping plate and the side plate include an initial spacing and a maximum allowable spacing. The wire auxiliary installation fixture includes a supporting plate and an elastic arm.

The supporting plate body includes a top end, a bottom end and a thickness-increasing section, the supporting plate body extends from the top end to the bottom end along a height direction, and the thickness-increasing section is located between the top end and the bottom end. The elastic arm and the supporting plate body form a receiving space for receiving the wire, and include a fixing portion and an elastic arm portion.

The fixing portion is fixed to the top end portion. The elastic arm portion includes a parallel extension section and an extension guide section, wherein the parallel extension section is integrally formed to extend from the fixing portion along the height direction toward the bottom end portion, and the extension guide section is integrally formed to extend from the parallel extension section along an inclined direction toward the bottom end portion, and the inclined direction is inclined to the height direction.

When the wire auxiliary installation fixture is placed at an installation position between the side plate and the clamping plate, the wire pushes against the elastic arm portion to open the elastic arm portion, so that the wire passes through the elastic arm and continues to enter between the clamping plate and the side plate.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the fixing portion is integrally formed and protrudes outward from the top end along a lateral direction, and the lateral direction is roughly perpendicular to the height direction.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the extended guide section further includes an inner guide slope and an outer guide slope, the inner guide slope faces the supporting plate body, and the outer guide slope faces away from the supporting plate body, and the outer guide slope pushes against the side plate to expand the distance between the clip plate and the side plate from the initial distance to an installation distance, wherein the installation distance is smaller than the maximum allowable distance.

Preferably, the thickness gradual increase section includes a plate guiding slope, the plate guiding slope is spaced from the inner guiding slope by an inner distance, the plate guiding slope is spaced from the outer guiding slope by an outer distance, and the inner distance and the outer distance decrease along the height direction toward the bottom end.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the thickness gradient section further includes an end flange and a snap-on structure, the end flange has an extension surface perpendicular to the height direction, the extension surface is adjacent to the bottom end, and the snap-on structure protrudes from the extension surface along the height direction to be snapped onto the side panel when the wire auxiliary mounting fixture is placed at the mounting position.

In addition, the supporting plate further includes at least one guiding and positioning structure, and the at least one guiding and positioning structure is connected to the end flange and is used to dock with the side plate to guide the wire auxiliary installation fixture to be placed at the installation position.

As described above, the present invention mainly guides the wires to enter between the clamp and the side plate through the inner guiding slope of the elastic arm. When the wires push the elastic arm and enter between the clamp and the side plate, the elastic arm will appropriately push the clamp so that the clamp expands to a degree that allows the wires to enter between the clamp and the side plate, thereby effectively preventing the clamp from plastically deforming due to excessive force applied by the user when manually pulling.

The specific embodiments of the present invention will be further described by the following embodiments and drawings.

Please refer to the third figure, which is a three-dimensional schematic diagram of a wire auxiliary installation fixture of a preferred embodiment of the present invention. As shown in the third figure, the present embodiment provides a wire auxiliary installation fixture 100, which includes a support plate 1 and two elastic arms 2 and 3. The support plate 1 extends from a top end 11 along a height direction D1 to a bottom end 12, and the support plate 1 also includes a thickness gradual increase section 13 and two guide positioning structures 14 and 15.

The thickness-gradient section 13 is located between the top end 11 and the bottom end 12, and the thickness of the thickness-gradient section 13 increases along the height direction D1 to form a plate guiding inclined surface 131. In addition, the thickness-gradient section 13 also has an end flange 132 and two buckle structures 133 and 134, and the end flange 132 has an extension surface 1321 perpendicular to the height direction D1, and the two buckle structures 133 and 134 protrude from the extension surface 1321 along the height direction D1.

The extending surface 1321 is adjacent to the bottom end portion 12 . The buckle structures 133 and 134 protrude from the extending surface 1321 along the height direction D1 , respectively, and are spaced apart from the bottom end portion 12 .

The two guide positioning structures 14 and 15 are integrally formed and extend from the end flange 132 along the height direction D1, and the two guide positioning structures 14 and 15 are spaced from the bottom end 12. In this embodiment, the two guide positioning structures 14 and 15 extend from the outer edge of the end flange 132, so that the distance between the two guide positioning structures 14 and 15 and the bottom end 12 is greater than the distance between the two snap structures 133 and 134 and the bottom end 12.

The elastic arm 2 includes a fixing portion 21 and an elastic arm portion 22. The fixing portion 21 is integrally formed and protrudes outward from the top end portion 11 along a side direction D2 substantially perpendicular to the height direction D1, so as to be fixedly connected to the top end portion 11.

The elastic arm portion 22 extends from the fixing portion 21 toward the bottom end portion 12, and further includes a parallel extension section 221 and an extension guide section 222. The parallel extension section 221 extends from the fixing portion 21 toward the bottom end portion 12 along the height direction D1 in an integral manner, and is thus arranged parallel to the supporting plate 1.

The extended guide section 222 is integrally formed from the end of the parallel extended section 221 and extends toward the bottom end portion 12 along an inclined direction D3 inclined to the height direction D1, and the extended guide section 222 has an outer guide slope 2221 and an inner guide slope 2222 arranged opposite to each other, the outer guide slope 2221 is facing away from the supporting plate 1, and the inner guide slope 2222 is facing the supporting plate 1. The outer guide slope 2221 and the inner guide slope 2222 are respectively separated from the fixing portion 21 by an outer distance d1 and an inner distance d2, and both the outer distance d1 and the inner distance d2 decrease along the height direction D1.

In addition, in this embodiment, the outer guiding inclined surface 2221 and the inner guiding inclined surface 2222 are arranged parallel to each other, but this is not limited to this in other embodiments.

The structure of the elastic arm 3 is the same as that of the above-mentioned elastic arm 2. The only difference is that the two are connected to each other at the top end 11 at a distance, so no further explanation is given here.

In this embodiment, since the elastic arms 2 and 3 extend from the top end 11 respectively and bend and extend toward the bottom end 12, the elastic arms 2 and 3 respectively form two accommodating spaces S1 and S2 that are laterally connected to each other with the supporting plate 1.

Please continue to refer to the fourth and fifth figures. The fourth figure is a three-dimensional schematic diagram showing the wire auxiliary installation fixture of the preferred embodiment of the present invention used for wire installation; the fifth figure is a three-dimensional schematic diagram showing the wires arranged in the accommodating space of the wire auxiliary installation fixture of the present invention.

As shown in the third to fifth figures, the two accommodating spaces S1 and S2 are used to temporarily receive the two wires 200a and 200b, and the wires 200a and 200b enter the two accommodating spaces S1 and S2 from the gaps formed by the elastic arms 2 and 3 and the supporting plate 1. Among them, since the wire auxiliary installation fixture 100 of this embodiment has two elastic arms 2 and 3, the two wires 200a and 200b with a certain length can be stably accommodated in the two accommodating spaces S1 and S2, but in other embodiments, even if the wire auxiliary installation fixture 100 has only one elastic arm 2, as long as the width of the elastic arm 2 is long enough, the wires can be effectively accommodated, so it is not limited to setting two elastic arms 2 and 3.

Please continue to refer to Figures 6 to 9. Figure 6 is a three-dimensional exploded schematic diagram showing the wire being installed in the server case through the wire auxiliary installation fixture of the present invention; Figure 7 is a three-dimensional schematic diagram showing the installation position of the wire auxiliary installation fixture of the present invention set in the server case; Figure 8 is a B-B cross-sectional schematic diagram of Figure 7; Figure 9 is a cross-sectional schematic diagram showing the wire passing through the support plate and the elastic arm and entering between the side plate and the clamping plate.

As shown in the third to ninth figures, after the two wires 200a and 200b are placed in the wire auxiliary installation fixture 100, the user can connect them to the side plate 301 through the guidance of the guide positioning structures 14 and 15, so that the two buckle structures 133 and 134 are buckled on the side plate 301 respectively, thereby placing the wire auxiliary installation fixture 100 in an installation position. Among them, since the distance between the two guiding and positioning structures 14 and 15 and the bottom end portion 12 is greater than the distance between the two snap structures 133 and 134 and the bottom end portion 12, the two guiding and positioning structures 14 and 15 mainly utilize the gap formed with the bottom end portion 12 to roughly fit and connect to the side plate 301, so that the two snap structures 133 and 134 are guided and more easily aligned with the side plate 301 and snapped on the side plate 301.

As mentioned above, when the wire auxiliary installation fixture 100 is placed at the installation position, the two elastic arms 2 and 3 will extend into the space between the clamping plate 302 and the side plate 301 respectively, so that the gap formed by the support plate 1 and the two elastic arms 2 and 3 is connected to the sandwich space S3 between the clamping plate 302 and the side plate 301. In this way, the user can push the two wires 200a and 200b into the sandwich space S3 between the clamping plate 302 and the side plate 301 by pushing the two ends of the two wires 200a and 200b extending out of the accommodating spaces S1 and S2.

Taking the elastic arm 2 as an example, the elastic arm 2 has an outer guiding slope 2221 and an inner guiding slope 2222, and the outer guiding slope 2221 and the inner guiding slope 2222 are respectively separated from the plate guiding slope 131 by an outer distance d1 and an inner distance d2, and the outer distance d1 and the inner distance d2 both decrease along the height direction D1. Therefore, when the two wires 200a and 200b are operated to move along the height direction D1, the two wires 200a and 200b will abut against the inner guide slope 2222 and the plate guide slope 131, and then be guided by the inner guide slope 2222 and the plate guide slope 131 to move toward the gap between the clamping plate 302 and the side plate 301.

However, since the supporting plate 1 to which the plate guiding slope 131 belongs is a relatively fixed element, when the two wires 200a and 200b abut against the inner guiding slope 2222 and the plate guiding slope 131, the elastic arm 2 absorbs the pushing force and produces elastic deformation, thereby pushing the elastic arm 2 open. At the same time as the elastic arm 2 is pushed, the outer guiding slope 2221 is also pushed. The clamping plate 302 is pressed against the side plate 301, so that the distance between the clamping plate 302 and the side plate 301 is expanded from an initial distance (not shown in the figure, i.e., the shortest distance between the clamping plate 302 and the side plate 301 in the eighth figure) to an installation distance (not shown in the figure, i.e., the shortest distance between the clamping plate 302 and the side plate 301 in the ninth figure), so that the two wires 200a and 200b pass through the elastic arm 2 and slide into the space between the clamping plate 302 and the side plate 301.

Among them, since the wire auxiliary installation fixture 100 of this embodiment is mainly to allow the two wires 200a and 200b to enter between the clamping plate 302 and the side plate 301 through the guidance of the inner guide slope 2222, although the two wires 200a and 200b will push the elastic arm 2 when passing through the elastic arm 2, and the elastic arm 2 pushes the clamping plate 302, thereby expanding the distance between the clamping plate 302 and the side plate 301 from the initial distance to the installation distance, but since this installation distance is the minimum distance required for the two wires 200a and 200b to pass through the elastic arm 2, Therefore, the installation distance will be smaller than the maximum allowable distance when the clamping plate 302 is pushed and opened to a maximum elastic deformation relative to the side plate 301. Therefore, when the two wires 200a and 200b are installed between the clamping plate 302 and the side plate 301 by the wire auxiliary installation fixture 100 of this embodiment, it can be effectively ensured that the deformation of the clamping plate 302 will not exceed the maximum elastic deformation. After the two wires 200a and 200b are installed between the clamping plate 302 and the side plate 301, the clamping plate 302 can return to its original position and be tightly attached to the side plate 301.

In summary, compared with the server case of the prior art, when installing cables, it is easy for the clamping plate to be plastically deformed due to the operator's manual force of pulling the clamping plate too much. The cable auxiliary installation fixture of the present invention mainly guides the cables into the space between the clamping plate and the side plate through the inner guiding slope of the elastic arm, and because the cable auxiliary installation fixture is set at the installation position When the clamp is in the correct position, the elastic arm will extend into the space between the clamp and the side plate. Therefore, when the wire pushes the elastic arm and enters the space between the clamp and the side plate, the elastic arm will appropriately push the clamp so that the clamp expands just enough to allow the wire to enter the space between the clamp and the side plate. This effectively prevents the clamp from plastically deforming due to excessive force applied by the user when manually pulling it.

In addition, since the present invention also uses the inner side guiding slope and the plate body guiding slope to guide the wire to slide between the clamping plate and the side plate, it can also effectively prevent the wire from being scratched when it is placed between the clamping plate and the side plate.

The wire auxiliary installation fixture provided in the preferred embodiment of the present invention can be used, for example, for wire installation in a server host, wherein the server host can be used for artificial intelligence (AI) computing, edge computing, etc., and can also be used as a 5G server, cloud server, or Internet of Vehicles server, etc.

The above detailed description of the preferred specific embodiments is intended to more clearly describe the features and spirit of the present invention, but is not intended to limit the scope of the present invention by the preferred specific embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent application for the present invention.
