Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 4, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention, and fig. 4 is a schematic view of another view of fig. 1.
In one embodiment of the present invention, the core components of the sliding power transmission structure include a conductive bar 2 and a sliding electrical connector 3.
The conductive bars 2 are disposed on the side wall of the box 1 and distributed along the installation direction of the box 1 (i.e. the push-pull direction of the motherboard during maintenance in the box 1), which is also the length direction of the box 1. The conducting bar 2 is electrically connected with a power supply of the server, electronic components mounted on the conducting bar 2 can be powered by a power supply loop on the mainboard, and a negative electrode electric bar 201 and a positive electrode electric bar 202 are respectively arranged on the surface and the bottom surface of the conducting bar 2 for convenient power supply connection.
The sliding electrical connector 3 is slidably arranged on the conductor bar 2 and can move synchronously therewith when the main board is pushed and pulled by a maintenance person. A first conductive plate 301 and a second conductive plate 302 are respectively disposed on the surface of the sliding electrical connector 3, and are respectively used for being correspondingly connected with the negative electrode electrical bar 201 and the positive electrode electrical bar 202 disposed on the conductive bar 2, and the first conductive plate 301 and the second conductive plate 302 are also respectively connected into the power supply loop of the motherboard at the same time. It is important that the first conductive plate 301 and the second conductive plate 302 can maintain stable electrical connection with the negative electrode row 201 and the positive electrode row 202, respectively, when the sliding electrical connector 3 slides back and forth on the conductive row 2.
Thus, through the electrical connection between the first conductive plate 301 and the second conductive plate 302 on the sliding electrical connector 3 to the negative electrode electrical bar 201 and the positive electrode electrical bar 202 on the electrical bar 2, a current bridge can be formed between the server power supply and the motherboard, so that the server power supply can smoothly supply power to the motherboard through the electrical bar 2 and the sliding electrical connector 3. When the server is maintained, a maintainer can pull out the mainboard from the box body 1, and the sliding electric connector 3 connected with the mainboard synchronously slides on the conductive bar 2 along with the movement of the mainboard, so that the stable electric connection is kept while the mainboard slides, and the stable power supply of the mainboard is further ensured.
Compared with the prior art, the embodiment does not need to use components such as a cable arm or a cable chain with large volume and large weight as a current bridge between the mainboard and the server power supply, so that the occupation of the power supply structure on the space can be greatly reduced, and the influence on the heat dissipation efficiency of the server is avoided.
In a preferred embodiment of the conductor bar 2, the conductor bar 2 may be rectangular, and the cross-sectional shape of the conductor bar 2 may be rectangular, and one side of the conductor bar 2 may be fixedly connected to a side wall of the box 1. Generally, in the same server chassis, only one of the side walls needs to be provided with one conductive bar 2, and certainly, the left and right side walls can be provided with the conductive bars 2 at the same time. Specifically, one side of the conductive bar 2 may be suspended on the sidewall of the box 1 by an adhesive or a fastener, and the negative electrode bar 201 may be erected on the surface thereof along the length direction thereof, while the positive electrode bar 202 may be erected on the bottom surface thereof along the length direction thereof. Of course, the arrangement orientations of the negative electrode row 201 and the positive electrode row 202 on the conductive row 2 can be interchanged.
Further, to improve the conductivity of the conductive bar 2, the negative electrode bar 201 and the positive electrode bar 202 may be both copper bars. Of course, the conductive bar 2 may also be made of other metal materials, such as silver bar. Meanwhile, in order to improve the structural specification and facilitate the reciprocating sliding motion of the sliding electrical connector 3 thereon, in this embodiment, the negative electrode row 201 and the positive electrode row 202 may be disposed over and under the conductive row 2. Of course, it is also possible to arrange the two offset from each other.
In addition, in order to facilitate the electrical connection between the sliding electrical connector 3 and the motherboard, the present embodiment provides a connection cable 306 on both ends of the first conductive plate 301 and the second conductive plate 302. Thus, one end of one of the connection cables 306 is connected to the negative electrode row 201 through the first conductive plate 301, and the other end thereof is connected to a corresponding terminal of the power supply loop on the motherboard; another connection cable 306 has one end connected to the positive electrode row 202 via the second conductive plate 302 and the other end connected to a corresponding terminal of the power supply circuit on the main board.
As shown in fig. 2 and 3, fig. 2 is a schematic diagram showing a specific structure of the sliding electrical connector shown in fig. 1, and fig. 3 is a left side view of fig. 2.
In a preferred embodiment with respect to the sliding electrical connector 3, the sliding electrical connector 3 mainly comprises a sliding frame 303. The sliding frame 303 is a long groove, i.e., has a long sliding groove and two side walls. When the sliding electrical connector 3 is mounted on the conductive bar 2, the conductive bar 2 can be formed into a half-wrapped structure by the sliding frame 303, that is, the conductive bar 2 is inserted into the long sliding slot of the sliding frame 303 along the length direction thereof and slides relatively in the long sliding slot. Meanwhile, the first conductive plate 301 may be connected to a top side wall of the sliding frame 303, and correspondingly, the second conductive plate 302 may be connected to a bottom side wall of the sliding frame 303. In order to ensure that the sliding frame 303 slides relative to the conductive bar 2, the first conductive plate 301 and the second conductive plate 302 can be electrically connected to the corresponding negative electrode electrical bar 201 or the positive electrode electrical bar 202, in this embodiment, the end of the first conductive plate 301 clamps the negative electrode electrical bar 201, and the end of the second conductive plate 302 clamps the positive electrode electrical bar 202, so that the clamping force is utilized to ensure the clamping and the abutting between the two.
Further, in order to improve the connection tightness and stability between the first conductive plate 301 and the second conductive plate 302 and the corresponding negative electrode electrical bar 201 or positive electrode electrical bar 202 when the sliding frame 303 slides relative to the conductive bar 2, in this embodiment, one side of the first conductive plate 301 is connected to the top side wall of the sliding frame 303 in a turnable manner, and correspondingly, one side of the second conductive plate 302 is connected to the bottom side wall of the sliding frame 303 in a turnable manner. Meanwhile, at the connecting positions of the first and second conductive plates 301 and 302 and the sliding frame 303, there are provided coil spring pins 4, and the coil spring pins 4 have spring-like elastic forces in the circumferential direction, and have a structure such that, in a natural state, the first and second conductive plates 301 and 302 maintain elasticity for rotating toward (the long slide groove of) the sliding frame 303. That is, in a natural state, the first conductive plate 301 and the second conductive plate 302 are turned inward by a certain angle and have a tendency to spring back. With this arrangement, when the sliding electrical connector 3 is mounted on the conductive bar 2, the conductive bar 2 is inevitably inserted into the long sliding slot of the sliding frame 303, and in the process, the conductive bar 2 is required to be pushed outward to separate the first conductive plate 301 and the second conductive plate 302, so that the first conductive plate 301 and the second conductive plate 302 maintain the clamping force on the inner conductive bar 2.
Furthermore, in order to ensure the stability of the installation of the conductive bar 2 and the sliding electrical connector 3, an elastic contact plate 304 is further disposed on the bottom surface of the long sliding slot of the sliding frame 303. The elastic contact plate 304 is an elastic structure, and has an elastic force in a direction perpendicular to the bottom surface of the sliding frame 303, when the conductive bar 2 is inserted into the long sliding slot of the sliding electrical connector 3, the side surface of the conductive bar 2 needs to press the elastic contact plate 304 with force, so that the elastic contact plate 304 generates elastic deformation, and accumulates the elastic force, so that after the conductive bar 2 and the sliding electrical connector 3 are installed, the pressing force on the conductive bar 2 is maintained, and the installation stability of the two is ensured. Specifically, the elastic abutting plate 304 is an arc-shaped plate that is bent along the length direction, and has a plurality of arc-shaped bending structures, and it is these arc-shaped bending structures that make the elastic abutting plate 304 generate elasticity. Of course, the specific structure of the elastic abutting plate 304 is not limited to an arc-shaped plate, and a steel plate spring structure can be adopted.
Similarly, in the present embodiment, a sliding abutting plate 305 is further provided on the inner surfaces of the first conductive plate 301 and the second conductive plate 302, and the sliding abutting plate 305 has the same function as the elastic abutting plate 304 described above, and is used to improve the mounting stability. Specifically, the outer surface of the sliding contact plate 305 may be fixed to the inner surfaces of the first conductive plate 301 and the second conductive plate 302 by an adhesive or the like, and meanwhile, the inner surface of the sliding contact plate 305 is smooth and is in contact with the corresponding negative electrode row 201 or positive electrode row 202. The sliding abutting plate 305 itself may have elasticity or not, and because the first conductive plate 301 and the second conductive plate 302 connected thereto are respectively rotatably connected to the sliding frame 303, when the surface of the negative electrode row 201 or the positive electrode row 202 is uneven during the sliding process of the sliding electrical connector 3, the sliding abutting plate 305 can push the first conductive plate 301 or the second conductive plate 302 open in a smooth manner, so that the two rotate at a certain angle and still keep pressing under the action of the coil spring pin 4.
The embodiment further provides a server chassis, which mainly includes a box 1 and a sliding power transmission structure disposed in the box 1, wherein specific contents of the sliding power transmission structure are the same as those described above, and are not described herein again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
