Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrically conductive connection, in particular to a dustproof connection device of a host server. BACKGROUND

[0002] In the process of cable connection of the host server, the cable is prone to poor contact. When the cable connection is not fully contacted, a large resistance will be generated when the current passes, thereby causing a high temperature at the connection point. The continuous high temperature will accelerate the aging of the cable insulation layer and even directly cause the cable to be damaged. In addition, the wires of the cable are prone to inconsistent lengths after being fixedly connected. When the cable is subjected to external tension, the wire with shorter length will bear the entire stress due to being subjected to stress first, and in the long run, the wire is prone to breakage, ultimately causing the cable to fail as a whole. In addition, the elastic contact piece of the cable will gradually lose its elasticity after long-term use, resulting in a decrease in stress, which breaks the stable contact state originally generated by the elastic contact, increases the contact resistance, and causes the current transmission to be blocked, thereby causing the cable to fail and posing a safety hazard to the operation of the equipment.

Those skilled in the art should be able to understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] The following reference Figures 1 to 14 This invention describes a dustproof connection device for a host server.

[0038] This embodiment provides a dustproof connection device for a host server. The dustproof connection device for a host server generally includes: a first connection part 100, a second connection part 200, and a third connection part 300.

[0039] The first connecting part 100 holds the first cable 110. One end of the second connecting part 200 is connected to the first connecting part 100, and a plurality of conductive pins 210 are provided therein. Each pin 210 is connected to a conductive spring piece 211 at the end facing the first connecting part 100, and a rotating shaft 220 passes through the center of the spring piece 211. A baffle 221 is provided on the rotating shaft 220, and the multiple wires 111 of the first cable 110 are respectively clamped between the multiple baffles 221 and the multiple spring pieces 211, and are wound around the rotating shaft 220 as the rotating shaft 220 rotates. The spring piece 211 has a spherical curved surface, and its center protrudes towards the baffle 221. The third connecting part 300 is connected to the other end of the second connecting part 200, and a plurality of socket seats 310 adapted to the pins 210 are provided therein, and the socket seats 310 are connected to the second cable 320.

[0040] In this embodiment, by setting a spring piece 211 and a rotating shaft 220 with a baffle 221, the wire 111 is clamped between the spring piece 211 and the baffle 221. As the rotating shaft 220 rotates, the wire 111 is wrapped around the spring piece 211 in a spiral shape, thereby increasing the contact area between the wire 111 and the spring piece 211 and reducing the contact resistance between the wire 111 and the spring piece 211. This not only improves the current transmission effect of the wire 111, but also avoids high temperature at the contact point between the wire 111 and the spring piece 211, reduces safety risks, and ensures the service life of the device.

[0041] In this embodiment, the spring piece 211 is spherically curved, so that when the baffle 221 and the spring piece 211 press against the wire 111, the wire 111 closer to the inner circle is pressed tighter. When the first cable 110 is pulled by an external force, under the compression of the spring piece 211 and the baffle 221, only the outer circle of the vortex-shaped wire 111 will be pulled and deformed, while the inner circle of the wire 111 can still maintain good contact with the spring piece 211, thereby ensuring the conductivity effect.

[0042] Furthermore, when the first cable 110 is pulled by an external force, the outer ring of conductors 111 tightens around the spring piece 211 under the action of tension, while the inner ring of multi-layer conductors 111 squeezed together will squeeze the spring piece 211 in the vertical direction, increasing the deformation of the spring piece 211 and thus increasing the elasticity of the spring piece 211. This compensates for the elasticity loss that may occur in the spring piece 211 due to long-term use, ensures the contact effect between the conductors 111 and the spring piece 211, and increases the service life.

[0043] In a further embodiment, each rotating shaft 220 has a transmission gear 222 at the end away from the spring piece 211. A first sleeve 120 is fitted onto the end of the first connecting portion 100 near the second connecting portion 200. Multiple racks 121 are spaced apart on the inner wall of the first sleeve 120, with each rack 121 corresponding to one of the transmission gears 222. During the connection process between the first connecting portion 100 and the second connecting portion 200, the first sleeve 120 gradually approaches the second connecting portion 200, causing the racks 121 and transmission gears 222 to mesh, thereby driving the rotating shaft 220 to rotate and causing the wire 111 to wind around the spring piece 211.

[0044] In this embodiment, multiple racks 121 opposite to the transmission gear 222 are provided on the first sleeve 120. When the first sleeve 120 gradually approaches the second connecting part 200, the racks 121 mesh with the transmission gear 222 and push the transmission gear 222 to rotate, thereby causing multiple rotating shafts 220 to rotate synchronously, and thus causing the wire 111 to rotate around the rotating shaft 220. This not only has a simple structure, but also operates stably.

[0045] Furthermore, when the conductor 111 is wound under the drive of the rotating shaft 220, the tension applied to the conductor 111 by the rotating shaft 220 is related to the length of the conductor 111. The shorter the length of the conductor 111, the greater the tension applied to the conductor 111 by the rotating shaft 220, which makes the conductor 111 wound more tightly around the rotating shaft 220 (i.e., the winding length of the conductor 111 is negatively correlated with the total length of the conductor 111). Therefore, after the rotating shaft 220 stops rotating, the variance among the remaining lengths of each conductor 111 decreases, so that when the first cable 110 is subjected to external tension, the force on each conductor 111 is more evenly distributed, thereby avoiding individual conductors 111 being subjected to force alone, reducing safety risks, and improving service life.

[0046] like Figure 5 As shown, the axis of the rotating shaft 220 is perpendicular to the axis of the first sleeve 120, and the rotating shaft 220 is also perpendicular to the spring piece 211. This makes the tension applied to the wire 111 more stable when the rotating shaft 220 rotates, thus making the winding of the wire 111 smoother. Multiple rotating shafts 220 are staggered on the second connecting part 200, making the structure more compact.

[0047] In a further embodiment, the rotating shaft 220 is threadedly connected to the second connecting part 200, so that when the rotating shaft 220 rotates and winds the wire 111, it approaches the spring piece 211 along the axial direction.

[0048] like Figure 11 As shown, the side wall of the rotating shaft 220 is provided with external threads. The end of the second connecting portion 200 facing the first connecting portion 100 has a mounting groove 230 for placing the rotating shaft 220, and the area within the mounting groove 230 opposite to the side wall of the rotating shaft 220 is provided with corresponding internal threads. An end cap 240 is also provided at the end of the second connecting portion 200 facing the first connecting portion 100 to close the mounting groove 230 and prevent the rotating shaft 220 from shifting. Similarly, the area on the end cap 240 opposite to the side wall of the rotating shaft 220 is also provided with corresponding internal threads. A clearance groove is also provided on the end cap 240 to allow the rack 121 to pass through the end cap 240 and mesh with the transmission gear 222.

[0049] In this embodiment, the rotating shaft 220 and the second connecting part 200 are threaded together, allowing the rotating shaft 220 to move axially when it rotates. When the rotating shaft 220 rotates and winds the wire 111, it moves axially closer to the spring piece 211, thereby compressing the wire 111 during the winding process. This reduces the contact resistance between the wire 111 and the spring piece 211, ensuring conductivity and service life.

[0050] In a further embodiment, a rotatable first rotating cylinder 250 is sleeved on one end of the second connecting part 200 facing the first connecting part 100, and the first sleeve 120 extends between the first rotating cylinder 250 and the second connecting part 200 and is threadedly connected to the first rotating cylinder 250.

[0051] In this embodiment, a rotatable first rotating cylinder 250 is fitted onto the second connecting part 200, and the first rotating cylinder 250 and the first sleeve 120 are threadedly connected. When the first rotating cylinder 250 rotates, the first sleeve 120 can be pushed to move axially through the threaded connection, so that the first sleeve 120 can be inserted between the first rotating cylinder 250 and the second connecting part 200, thereby engaging the rack 121 and the transmission gear 222. This not only makes the structure simple and stable and easy to operate, but also makes the connection between the first connecting part 100 and the second connecting part 200 tighter and less likely to fall off.

[0052] In other embodiments, the first connecting portion 100 and the second connecting portion 200 may be provided with corresponding slots and blocks. The first connecting portion 100 and the second connecting portion 200 are connected by an operator, so that the rack 121 and the transmission gear 222 mesh, and after driving the rotating shaft 220 to complete rotation, they are directly snapped together.

[0053] In a further embodiment, the second connecting part 200 is provided with a sliding groove 260, and the first sleeve 120 is provided with a corresponding slider 122.

[0054] In this embodiment, by providing a sliding groove 260 on the second connecting part 200 and a corresponding sliding groove 260 on the first sleeve 120, the first connecting part 100, which is threadedly connected to the first rotating drum 250, can move axially along a preset trajectory when the first rotating drum 250 rotates, so as to ensure that the rack 121 and the transmission gear 222 can smoothly contact and mesh.

[0055] In a further embodiment, a positioning groove 223 is provided on the rotating shaft 220. The positioning groove 223 is located between the spring piece 211 and the baffle 221 and is used to place the end of the wire 111.

[0056] In this embodiment, by setting a positioning groove 223 between the spring piece 211 and the baffle 221, and placing the end of the wire 111 in the positioning groove 223, the wire 111 is prevented from falling out between the baffle 221 and the spring piece 211 when the rotating shaft 220 rotates, thus ensuring the contact effect between the wire 111 and the spring piece 211.

[0057] In a further embodiment, a rotatable second rotating cylinder 270 is fitted onto one end of the second connecting portion 200 facing the third connecting portion 300, and the second rotating cylinder 270 and the third connecting portion 300 are threadedly connected. A first sliding plate 271 is provided inside the second connecting portion 200, and a plurality of pins 210 pass through the first sliding plate 271. A first compression spring 272 is provided between the first sliding plate 271 and the second connecting portion 200, and a first locking block 273 is provided on the inner side of the second connecting portion 200 to prevent the first sliding plate 271 from disengaging from the pins 210.

[0058] In this embodiment, a second rotating cylinder 270 is fitted onto one end of the second connecting part 200 facing the third connecting part 300, and the second rotating cylinder 270 and the third connecting part 300 are threadedly connected. This allows the third connecting part 300 to move axially along the second rotating cylinder 270 when the second rotating cylinder 270 rotates, thereby enabling the insertion socket 310 and the insertion pin 210 to smoothly engage.

[0059] Furthermore, in this embodiment, a first sliding plate 271 that can slide along the pin 210 is provided in the second connecting part 200, and a first compression spring 272 is provided between the first sliding plate 271 and the second connecting part 200. This allows the first sliding plate 271 to move to abut against the first locking block 273 when the pin 210 and the socket 310 are not aligned. This prevents external dust from entering the second connecting part 200 without disengaging from the pin 210, thereby avoiding dust accumulation on the pin 210 that could affect conductivity.

[0060] In some embodiments, the inner sides of the first rotating cylinder 250 and the second rotating cylinder 270 may be provided with retaining rings, and the outer sides of the second connecting portion 200 may be provided with corresponding annular grooves, so that the first rotating cylinder 250 and the second rotating cylinder 270 will not detach from the second connecting portion 200 when rotating relative to the second connecting portion 200. Each of the first rotating cylinder 250 and the second rotating cylinder 270 may be composed of two half-cylinders, which are spliced ​​and fitted onto the second connecting portion 200 and then connected together by bolts or other fasteners.

[0061] In a further embodiment, a second sliding plate 330 is provided inside the third connecting portion 300, and a plurality of socket seats 310 pass through the second sliding plate 330. A second compression spring 340 is provided between the second sliding plate 330 and the bottom 131 of the third connecting portion 300. A second locking block 311 is provided on the outer side of the socket seat 310 to prevent the second sliding plate 330 from disengaging from the socket seat 310.

[0062] In this embodiment, a second sliding plate 330 is provided inside the third connecting part 300, and a second compression spring 340 is provided between the second sliding plate 330 and the third connecting part 300. This allows the second sliding plate 330 to move to abut against the second locking block 311 when the pin 210 and the socket 310 are not aligned. This prevents external dust from entering the third connecting part 300 without disengaging from the socket 310, thereby avoiding dust accumulation on the socket 310 that could affect conductivity.

[0063] In a further embodiment, friction stripes 280 are provided on the outer sides of both the first rotating drum 250 and the second rotating drum 270.

[0064] In this embodiment, friction stripes 280 are provided on the outer sides of the first rotating drum 250 and the second rotating drum 270, thereby increasing the coefficient of friction of the outer walls of the first rotating drum 250 and the second rotating drum 270, which reduces the force required for the operator to rotate the first rotating drum 250 and the second rotating drum 270, and thus reduces the difficulty of operation.

[0065] In a further embodiment, a second sleeve 130 is fitted onto the end of the first connecting portion 100 away from the second connecting portion 200. The bottom 131 of the second sleeve 130 is conical, and the end wall of the first connecting portion 100 abuts against the bottom 131 of the second sleeve 130. An annular groove 140 is formed at the end of the first connecting portion 100 near the second sleeve 130, and a friction ring 141 is disposed within the annular groove 140, which is fitted onto the first cable 110. A plurality of through grooves 150 are spaced apart on the groove wall of the annular groove 140.

[0066] In this embodiment, a second sleeve 130 is fitted onto the first connecting part 100. The conical bottom 131 of the second sleeve 130 abuts against the end wall of the first connecting part 100, causing the end wall of the first connecting part 100 to be squeezed inward. This causes the friction ring 141 placed in the annular groove 140 to be squeezed, thereby causing the first cable 110 to be clamped by the friction ring 141.

[0067] In some preferred embodiments, the second sleeve 130 is threadedly connected to the first sleeve 120, allowing the second sleeve 130 to move axially closer to or further away from the first connecting portion 100 when rotating relative to the first sleeve 120. The end wall of the first connecting portion 100 abuts against or disengages from the tapered bottom 131 of the second sleeve 130, causing the friction ring 141 to be compressed or relaxed. This ensures the clamping effect on the first cable 110 while allowing the length of the first cable 110 to be adjusted. The outer side of the second sleeve 130 may also be provided with stripes to increase friction and reduce operational difficulty.

[0068] The specific working process of the dustproof connection device for the host server provided by the present invention will be described in conjunction with the above embodiments:

[0069] First, the first cable 110 is passed through the first connector 100 and the friction ring 141.

[0070] Then, the second sleeve 130 is controlled to rotate and connect with the first sleeve 120, so that the conical bottom 131 of the second sleeve 130 presses against the end wall of the first connecting part 100, so that the friction ring 141 is squeezed, thereby pressing the first cable 110.

[0071] Next, each wire 111 of the first cable 110 is passed through the end cap 240 and inserted into the positioning groove 223 on the corresponding rotating shaft 220. After the second connecting part 200 is closed with the end cap 240, the first rotating drum 250 is controlled to rotate and connect with the first sleeve 120, so that the first sleeve 120 approaches the second connecting part 200 axially.

[0072] As the first sleeve 120 approaches the second connecting part 200, the rack 121 on the first sleeve 120 meshes with the transmission gear 222 on the rotating shaft 220, driving the transmission gear 222 to rotate, thereby causing the rotating shaft 220 to rotate and causing the wire 111 to wind around the spring piece 211. Simultaneously, as the rotating shaft 220 rotates, it moves axially closer to the spring piece 211, pressing the wire 111 tightly between the baffle 221 and the spring piece 211, thus ensuring electrical conductivity.

[0073] Subsequently, the second rotating drum 270 is controlled to rotate and connect with the third connecting part 300, causing the third connecting part 300 to move axially closer to the second connecting part 200, thereby allowing the pin 210 to be inserted into the socket 310. During the process of the pin 210 being inserted into the socket 310, the first sliding plate 271 and the second sliding plate 330 are pressed and slid by the socket 310 and the pin 210, respectively, until the pin 210 and the socket 310 are fully engaged.

[0074] Furthermore, by rotating the second rotating drum 270 and the first rotating drum 250 in the opposite direction, the first connecting part 100, the second connecting part 200 and the third connecting part 300 can be disconnected.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
