In one embodiment of the present invention, the plastic fastening-free mounting structure of the server chassis mainly includes a PCB board 1, a mounting post 2, a connector 3 and an unlocking member 4.

The PCB 1 is mainly used for mounting various electronic components and plastic parts. The mounting posts 2 are arranged on the surface of the PCB board 1 and are mainly used for providing mounting positioning for mounting of various plastic parts. The outer wall of the plastic part is provided with a connector 3, the connector 3 is mainly used for being matched with the mounting column 2, and when the plastic part is mounted on the PCB 1, the positioning and the fixing of the plastic part can be realized through the insertion and the matching between the connector 3 and the mounting column 2. Meanwhile, an unlocking piece 4 is further arranged on the connector 3, and the unlocking piece 4 is mainly used for releasing the connection through preset operation after the connector 3 and the mounting column 2 form plugging connection, so that the plastic piece can be smoothly detached from the PCB 1.

Therefore, the fastening-free mounting structure for the plastic part of the server case provided by the embodiment can complete the positioning and mounting fastening effects of the plastic part on the PCB board 1 at the same time by only inserting the connector 3 arranged on the plastic part into the mounting column 2 arranged on the surface of the PCB board 1 when the plastic part is mounted on the PCB board 1. Meanwhile, when the plastic part needs to be disassembled, the unlocking piece 4 is operated to release the plugging connection between the mounting column 2 and the connector 3.

Compare in prior art, this embodiment utilizes the erection column 2 that sets up on the PCB board 1 and moulds inserting the cooperation of connecing between the connector 3 of being equipped with on the outer wall, combines the unblock effect of unblock piece 4, realizes improving easy operation nature and convenience to moulding the swift dismouting under the high density framework.

In a preferred embodiment with respect to the mounting post 2, the mounting post 2 essentially comprises a post body 201, a slim rod body 202 and a guide cone 203. The upright column 201 may be erected on the surface of the PCB board 1, and may be disposed perpendicular to the surface of the PCB board 1. The slender rod body 202 is connected to the top end of the upright column 201, and the guide cone 203 is arranged at the top end of the slender rod body 202. Specifically, the diameter of the upright column 201 and the diameter of the bottom surface of the guide cone 203 are both larger than the diameter of the slender rod body 202, and a layer of annular groove is formed in the part, located on the slender rod body 202, of the upright column 201. Since the plastic part often has a certain height, the overall height of the mounting post 2 can be increased by the action of the thin rod body 202 when it is engaged with the connector 3 on the outer wall of the plastic part. The guide cone 203 at the top end is conical as a whole, and the surface of the guide cone is a curved cambered surface, so that the force dispersion effect is better, and when the mounting column 2 and the connector 3 form the inserting and matching process, the guide cone 203 can provide a guide for the inserting and mounting matching process.

Further, considering that the surface of the guide cone 203 inevitably forms a tight friction with the inner wall of the connector 3 when the guide cone 203 forms a mating fit with the connector 3, in order to improve the installation smoothness, the surface of the guide cone 203 is specifically a smooth surface, and may be treated by polishing or the like.

In a preferred embodiment with respect to the connector 3, the connector 3 basically comprises a bayonet ring 301 and a clamping element 302. The inserting ring 301 is connected to the outer wall of the plastic member, and the clamping member 302 is connected to the top surface of the inserting ring 301, and has elasticity, specifically, two elastic sheets are arranged opposite to each other and are closed together. In the natural state of the clamping piece 302 (i.e. when not mounted), the clamping edges on both sides of the clamping piece 302 are closed towards the middle and have a clamping gap which is smaller than the diameter of the base surface of the guide cone 203. In this way, when the inserting ring 301 is inserted and matched with the mounting post 2, the guide cone 203 on the mounting post 2 firstly passes through the inserting ring 301 and then enters the clamping gap of the clamping piece 302, and because the diameter of the clamping gap is smaller than that of the bottom surface of the guide cone 203, the guide cone 203 will continue to pull open the clamping piece 302 which is folded circumferentially, so that the clamping piece 302 is separated and elastically deformed towards two sides. When the fit between the mounting post 2 and the connector 3 is deepened, the bottom surface of the guide cone 203 completely passes through the clamping gap of the clamping member 302, and at this time, the thin rod 202 on the mounting post 2 enters the clamping gap, and the clamping member 302 is folded again under the action of the elastic force because the diameter of the thin rod 202 is smaller than that of the bottom surface of the guide cone 203, so that the thin rod 202 is clamped, and the bottom surface of the guide cone 203 is also pressed on the top surface of the clamping member 302, thereby primarily realizing the fastening of the connector 3.

Further, in order to improve the installation stability of the docking plug-in 3, the embodiment further sets a limiting ring 303 on the outer wall of the plastic part. Specifically, the limiting ring 303 is specifically located at a position above the clamping member 302 by a preset distance, and is mainly used for forming shaft hole matching with the guide cone 203 after the guide cone 203 completely passes through the clamping member 302, so as to fix the guide cone 203 at the current position and prevent the guide cone 203 from moving forward. Of course, the bottom surface of the molding also comes into contact with the surface of the PCB board 1 at this time.

In the same regard, the present embodiment also provides an abutment plate 304 on the end face of the clamping member 302. Specifically, the abutting plates 304 can be connected to both sides of the end face of the clamping member 302, and the surfaces thereof are flat surfaces, and are mainly used for abutting against the bottom surface of the guide cone 203 to support the guide cone 203 after the guide cone 203 is matched with the limiting ring 303.

Further, the present embodiment further provides a mounting seat 305 on the outer wall of the plastic member. Specifically, the mounting seat 305 may extend outward to a certain distance from the outer wall of the plastic part, and the inserting ring 301 is disposed on the mounting seat 305, so that the extending distance of the mounting seat 305 on the outer wall of the plastic part may cause the position of the inserting ring 301 on the outer wall to have a certain distance from the surface of the outer wall of the plastic part, that is, a certain reserved space exists between the whole connector 3 and the surface of the outer wall of the plastic part, and the reserved space is mainly used for reserving a movement space for the unlocking operation of the unlocking part 4.

In a preferred embodiment with respect to the unlocking member 4, the unlocking member 4 mainly includes a sliding plate 401, a compression ring 402, and a wing plate 403. The sliding plate 401 is slidably disposed on the rear side wall of the clamping member 302, and typically, a sliding groove is formed in the rear side wall of the clamping member 302 along the height (or length) direction thereof, and the sliding plate 401 is slidably mounted in the sliding groove. Considering that the limiting ring 303 above the clamping member 302 is connected to the outer wall of the plastic member, in order to facilitate the installation of the clamping member 302 and the connector 3 and the unlocking operation of the mating connector 3, in this embodiment, the sliding plate 401 may be a split structure, a gap is formed in the middle portion of the sliding plate 401 along the height direction, and the sliding plate 401 is formed into a type II structure with the left and right sides facing each other through the gap. A clamp ring 402 is provided at an upper position of the slide plate 401, while wing plates 403 are provided at both side positions of the slide plate 401.

Specifically, the compression ring 402 is mainly used to compress the top surface of the retainer ring 303 when the sliding plate 401 is mounted on the sliding groove, so as to limit and position the mounting depth of the unlocking member 4 on the connector 3. The wing plates 403 are triangular as a whole, have a width gradually increasing from top to bottom, and are similar to the shape of an airplane tail wing, and when the wing plates are arranged on both sides of the sliding plate 401, the width of the wing plates is gradually increased for the sliding plate 401.

To be engaged with the wing plate 403, driven posts 306 are provided at both side positions of the abutment plate 304. Specifically, the driven posts 306 can be fixed on both side edges of the abutting plate 304, and the driven posts 306 are generally horizontally disposed and extend toward the surface of the plastic member, such as the surface of the plastic member. Importantly, the driven post 306 is of such a length that it extends over the wings 403 on either side of the slide plate 401 and can abut and press against the inclined surfaces of the wings 403.

Thus, when the plug-in unit 3 needs to be unlocked, an operator only needs to pull the unlocking unit 4 upwards to slide the sliding plate 401 upwards in the sliding slot on the plug-in unit 3, in the sliding process of the sliding plate 401, due to the shape structure change of the wing plate 403, the whole width of the sliding plate 401 increases along with the ascending distance, and when the width increases to a certain extent, the inclined surface of the wing plate 403 abuts against the driven posts 306 arranged on the two sides of the abutting plate 304 and presses each other. Then the sliding plate 401 continues to rise, the inclined surface of the wing plate 403 will generate thrust towards the left and right sides to the driven column 306, so as to poke the driven column 306, the driven column 306 is arranged on the abutting plate 304, the abutting plate 304 is arranged on the clamping piece 302, therefore, in the continuous rising stroke of the sliding plate 401, the clamping piece 302 in the connector 3 can be poked by the thrust of the wing plate 403 to the driven column 306, so that the abutting plate 304 is no longer supported on the bottom surface of the guide cone 203, so that the bottom surface of the guide cone 203 is emptied, then the unlocking piece 4 continues to be lifted, so as to drive the connector 3 to be completely separated from the guide cone 203, and thus the fastening connection between the plastic piece and the mounting column 2 is released.

Further, in consideration of the necessity of an operator to pull up the slide plate 401 during unlocking by the unlocking member 4, the present embodiment is provided with an operation plate 404 at the top end position of the slide plate 401 for the convenience of operation. Specifically, the operating plate 404 may be a bent plate, which is convenient for an operator to hook the operating plate with fingers to apply force upwards. Meanwhile, in order to facilitate the operator to smoothly butt the plug-in unit 3 to generate an upward lifting force when the unlocking unit 4 is lifted, the inward extending edge 405 is disposed at the bottom end of the middle gap of the sliding plate 401 in the present embodiment. Specifically, the inwardly extending edge 405 extends to a certain distance toward the middle of the gap, and after the sliding plate 401 is lifted to a certain distance, the inwardly extending edge 405 can abut against the bottom surface of the retainer ring 303, so that the connector 3 can be pulled out from the mounting post 2 through the abutting point.

The embodiment further provides a server chassis, which mainly includes a box body and a plastic part fastening-free mounting structure disposed in the box body, wherein specific contents of the plastic part fastening-free mounting structure are the same as those of the above-mentioned related contents, 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.
