Description

TECHNICAL FIELD

[0001] The present invention relates to a quick release plastic connector, in particular, a quick release plastic connector for electronic equipment, such as a server. BACKGROUND

[0002] It is well known to use connectors, such as screws, to join two items together so that the items do not separate. Please refer to Figures 1 to Figure 4 which show a cover 30, such as a dust cover, attached to an electronic equipment 20, such as a server housing, using a plurality of existing connectors 10, such as silicone pull pins.

[0003] As shown in Figure 2 , the server housing 20 includes at least one storage device, such as a mechanical hard drive or a solid state hard drive (not shown), inside. In order to achieve the heat dissipation effect of the at least one storage device, a plurality of fans 201 arranged in a row are usually provided at an entrance position of the server housing 20, and each fan 201 is locked to a fixed plate 203 inside the server housing 20 using at least two screws 202. In order to avoid dust or foreign matter being sucked into the inside of the server housing 20 by the fans 201, the dust cover 30 is usually installed at the entrance position.

[0004] The dust cover 30 is attached to the entrance position of the server housing 20 by passing each of the plurality of silicone pull pins 10 through a predetermined plate hole 301 and being buckled into a positioning hole 204 provided in the corresponding fan 201.

[0005] As shown in Figure 1a and Figure 1b , one end of each of the plurality of silicone pull pins 10 is provided with a plurality of undulating stepped rods 101, and a conical disc 102 with a first abutting edge 103 is formed behind the stepped rods 101. The conical disc 102 is further connected to a smaller and equal diameter rod column 104 and at least one inclined wing 105 with a second abutting edge 106, which is larger in size than the rod column 104. The number of the at least one inclined wing 105 is a pair, and the end of the at least one inclined wing 105 is a largest rod cap 107.

[0006] As shown in Figures 2 to 4As shown, during assembly, the tapered disc 102 of each silicone pull pin 10 is first inserted into the plate hole 301 of the dust cover 30 and the positioning hole 204 of the fan 20. Then, using a clamping tool, such as a needle-nose plier, the tapered disc 102 is clamped and pulled inward until the tapered disc 102 deforms through the plate hole 301 and the positioning hole 204, the first abutting edge 103 abuts against the outer edge of the positioning hole 204, and the at least one slanted fin 105 deforms through the plate hole 301, the second abutting edge 106 abuts against the outer edge of the plate hole 301, and the rod cap 107 jointly clamps the plate hole 301.

[0007] This allows the dust cover 30 to be firmly combined with one side of the fans 201. However, the existing connecting member 10, such as the silicone pull pin, has the following disadvantages. First, the material of the silicone pull pin is not heat-resistant and is easily deformed after being heated. Second, the working space of the fans 20 is limited, making it difficult to pull the silicone pull pin 10. Third, the tapered disc 102 of the silicone pull pin 10 has a function of preventing the dust cover 30 from being removed after being installed in the server cabinet 20, which makes it difficult to clean the dust cover 30. In other words, the silicone pull pin 10 is a one-time product and cannot be reused, which is a common problem faced by related industries and needs to be improved. SUMMARY

[0008] The main purpose of the present application is to provide a quick-release plastic connecting member that is combined with a connected object, such as a cover, such as a dust cover, in an electronic device, such as a server cabinet, and has the functions of easy installation and removal, and is a reusable product, thereby increasing the convenience of use.

[0009] To achieve the above-mentioned purpose, the technical means adopted by the present application is to provide a quick-release plastic connecting member, comprising a geometrically shaped shaft, the outer surface of the shaft radially extending a plurality of flexible protrusions arranged in a regular or irregular manner, and the top of the shaft being integrally connected to a cap through a connecting column; and the top of the shaft further extending a pair of slanted fins, and a buckle being arranged between each slanted fin and the cap.

[0010] In an embodiment, the quick-release plastic connecting member is made of nylon and is integrally injection molded.

[0011] In an embodiment, the outer surface of the shaft is axially formed with at least two cutting surfaces, and each cutting surface radially extends a plurality of flexible protrusions arranged in a row.

[0012] In an embodiment, the shape of each protrusion is fin-shaped.

[0013] In one embodiment, the shaft further comprises a tapered end with a tapered bottom.

[0014] In one embodiment, the connecting post is in the shape of a flat post with a trapezoidal piece connecting between a pair of upright sections. BRIEF DESCRIPTION OF DRAWINGS

[0050] As shown in Figure 5a and Figure 5b , basically, the quick release plastic connector 4 of the present application, such as a quick release plastic rivet, is integrally formed, for example, by Nylon injection molding, and has the effect of being resistant to heat and not easily deformed by heat. Therefore, the quick release plastic connector 4 includes a geometrically shaped shaft 41, and the outer circumferential surface of the shaft 41 radially extends a plurality of protrusions 42 arranged in a regular or irregular manner and having flexibility. In an embodiment, the outer surface of the shaft 41 is axially formed with at least two cutting surfaces 411, for example, four cutting surfaces 411, and each cutting surface 411 radially extends a plurality of protrusions 42 arranged in a column and having flexibility, wherein each protrusion 42 is in the shape of a fin.

[0051] The shaft 41 further comprises a tapered end 412 at the bottom, and a largest size cap 43 at the top which is integrally connected by a connecting column 413; wherein the connecting column 413 is shaped as a flat column with a trapezoidal piece connecting between a pair of upright sections. In addition, the top of the shaft 41 further extends a pair of inclined wings 414, and each of the inclined wings 414 is provided with a buckle 415 between the cap 43.

[0052] Please refer to Figures 6 to 9 , which shows a diagram of the quick release plastic connector 4 and the connected object, such as a server case 20 and a cover 30, such as a dust cover, being quickly installed. As mentioned above, the server case 20 inside includes at least one storage device, such as a mechanical hard drive or a solid state hard drive (not shown in the figure), in order to achieve the heat dissipation effect of the at least one storage device, a plurality of fans 201 arranged in a row are usually arranged at an entrance position of the server case 20, and each fan 201 is locked on a fixed plate 203 inside the server case 20 by at least two screws 202. In order to avoid dust or foreign matter being sucked into the inside of the server case 20 by these fans 201, the dust cover 30 is usually installed at the entrance position.

[0053] Please refer to Figure 6 , when the dust cover 30 is pre-installed on the server case 20, first, the tapered end 412 of each quick release plastic connector 4 is inserted into each plate hole 301 of the dust cover 30, so that the shaft 41 and the protrusions 42 pass through the plate hole 301, until the pair of upright sections of the connecting column 413 are accommodated in the plate hole 301 (shown in Figure 9 ), and the buckle 415 is buckled in the plate hole 301 (shown in Figure 8 ), so as to achieve the effect that they are not easy to fall off, and the cap 43 abuts against the outer periphery of the plate hole 301, and the shaft 41 and the protrusions 42 extend from the inner surface of the dust cover 30.

[0054] Please refer to Figure 7 , then the shaft 41 of each quick release plastic connector 4 is aligned with and inserted into a positioning hole 204 corresponding to each fan 201. Since the protrusions 42 are flexible, when entering each positioning hole 204 with a smaller diameter, the protrusions 42 will be inclined and deformed in the direction of travel (shown in Figure 8 and Figure 9 ), so that the protrusions 42 form an interference anti-falling mode in the positioning hole 204, so that the dust cover 30 is connected to the entrance position of the server case 20.

[0055] Conversely, if the dust cover 30 is to be detached from the server casing 20, the user only needs to hold the dust cover 30 and pull it out, at which time the protrusions 42 on the shaft 41 will be tilted and deformed in the pulling direction until they are disengaged from the positioning holes 204, thereby removing the interference and allowing the quick-release plastic connector 4 to be reused in an environmentally friendly manner.

[0056] Therefore, through the implementation of the present application, the quick-release plastic connector and the connected object have the functions of easy installation and detachment. In particular, the quick-release plastic connector is made of nylon, which has the effects of heat resistance and resistance to deformation due to heat. In addition, the flexible design of the protrusions makes the quick-release plastic connector a reusable product, which is an unprecedented preferred structure for similar products.

[0057] The present application discloses a preferred embodiment. Any partial changes or modifications that are derived from the technical ideas of the present application and are easily understood by those skilled in the art do not deviate from the scope of protection of the present application.
