Detailed Description

In order to make the technical scheme and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

Terms of orientation such as "top", "bottom", "side", etc. in the embodiments of the present disclosure may be referenced with respect to the relative relationship of orientation shown in fig. 2, and are used merely to more clearly describe structures and relationships between structures, and are not intended to describe absolute orientations. The orientation may change when the product is placed in different orientations, e.g. "top", "bottom" may be interchanged.

Electronic devices such as network devices utilize slots to receive a single board that is inserted into a corresponding slot and connected with its connector to a connector inside the slot. Because the network equipment generally adopts the air cooling system to dissipate heat, and the connector arranged in the slot is generally in an air flow area, in this way, in the state of the slot being empty, dust and other foreign matters can be deposited on the connector in the empty slot (i.e. the idle slot) along with the air flow, thereby affecting the electric connection effect of the connector and deteriorating the signal quality so as to affect the performance of the network equipment.

The related art uses a dummy panel inserted into the empty slot to prevent dust on the connector, wherein the dummy panel includes a partition plate integrally sealed to block the connector from the air flow, thereby preventing foreign matters such as dust from depositing on the connector.

However, for an electronic device having at least two stages of veneers in the direction of airflow, for example, fig. 1 illustrates that the electronic device includes a bezel module 200 and a fan module 300, the bezel module 200 including: the first plug frame unit 201 and the second plug frame unit 202 are sequentially arranged along the air flow direction, wherein the empty slot 2010 is located in the first plug frame unit 201, and correspondingly, the connector 2020 corresponding to the empty slot 2010 is located in the second plug frame unit 202. The fan module 300 is configured to provide an airflow such that the airflow flows from the first bezel unit 201 to the second bezel unit 202, i.e., fig. 1 illustrates that the type of duct inside the electronic device is a front-to-back duct.

If the related art dummy panel is used, the partition board thereof cuts off the air flow, so that the connector 2020 cannot contact with the air flow, and the second plug frame unit 202 corresponding to the shielded connector 2020 cannot be ventilated, thereby affecting the smooth heat dissipation.

In view of the technical problems of the related art, an embodiment of the present disclosure provides a connector dust-proof member 100, as shown in fig. 2, the connector dust-proof member 100 includes: the panel portion 1, the bottom plate portion 2, and the dust-proof portion 3 are located at opposite ends of the bottom plate portion 2, respectively, the panel portion 1 and the dust-proof portion 3. Wherein the dust prevention part 3 comprises a dust prevention structure 31 and an air guiding structure 32, the dust prevention structure 31 is configured to shield the connector 2020 to realize dust prevention, and the air guiding structure 32 is configured to guide air flow out of a side area of the connector 2020.

The connector dust guard 100 provided in the embodiments of the present disclosure can be inserted into the empty slot 2010 of the electronic device as a dummy panel module, wherein fig. 3 illustrates the connector dust guard 100 being used in the empty slot 2010 of the plug frame module of the orthogonal architecture, and fig. 4 illustrates the connector dust guard 100 being used in the empty slot 2010 of the plug frame module of the backplane architecture.

The connector dust-proof piece 100 provided by the embodiment of the disclosure can be inserted into the empty slot 2010, and meanwhile, the dust-proof and air guiding effects are achieved. Wherein the panel part 1 provides a dummy panel, the dust-proof part 3 shields the connector 2020 inside the hollow 2010 by the dust-proof structure 31 thereof to realize dust prevention, and the dust-proof part 3 leads the air flow out of the side area of the connector 2020 by the air guiding structure 32 thereof, thus, the air flow is prevented from directly flowing through the connector 2020 to deposit foreign matters such as dust thereon while realizing the air guiding effect. It can be seen that, the connector dust-proof member 100 provided in the embodiment of the present disclosure, on the basis of maintaining a simple structure and convenient operation, can provide a ventilation windage condition similar to that of a real veneer, and guide an air flow to a side region of the connector 2020, so that the pins of the connector 2020 are in a low-speed region, the heat dissipation performance of the electronic device is not affected, and the intrusion of dust, sundries and the like into the pins of the connector 2020 can be effectively prevented. The connector dust-proof member 100 has a stronger adaptability to different air channels, for example, it is suitable for an electronic device having at least two stages of single boards 2011 along the airflow direction and performing cascade heat dissipation.

It will be appreciated that the connector dust-proof member 100 provided in the embodiments of the present disclosure may have dimensions such as height, width, and depth that are consistent with the corresponding dimensions of a conventional veneer to ensure smooth insertion into the empty slot 2010 of the electronic device.

Some suitable implementations of the dust guard 3 are described below exemplarily:

In use, the spacer 311 is opposite the plug end of the connector 2020; further referring to fig. 7 and 8, the air guiding body 321 includes an air guiding cavity 3211 and an air outlet 3212, which are connected, the air guiding body 321 is convexly disposed on the partition board 311 and is located on one side of the connector 2020, the air outlet 3212 is located on one end of the air guiding body 321 far away from the partition board 311, and the air guiding cavity 3211 is formed inside the air guiding body 321.

The spacer 311 is opposite to the insertion end (i.e., the free end of the pin) of the connector 2020, so that the connector 2020 can be shielded by the spacer 311 to prevent dust. The air guide body 321 is arranged on the partition board 311 in a protruding manner and extends into one side of the connector 2020, so that air flow is guided out sequentially by the air guide cavity 3211 and the air outlet 3212, and then guided out from one side of the connector 2020, so that insertion pins of the connector 2020 are prevented from being invaded, and a heat dissipation effect is ensured on the premise of ensuring a dust prevention effect.

The number of connectors 2020 in the empty slots 2010 of the electronic device may be plural, and in this case, the number of dustproof structures 31 may be the same as the number of connectors 2020, where fig. 7 illustrates that the number of dustproof structures 31 and air guiding structures 32 are plural, and the dustproof structures 31 and the air guiding structures 32 are alternately arranged in sequence.

In this case, the partition 311 is disposed opposite the insertion end of the connector 2020, and the wind guide 321 protrudes into a side region between any adjacent two connectors 2020.

In some examples, referring to fig. 9, 10, 11, and 12, an end of the air guide body 321 away from the partition 311 and a mating end of the connector 2020 have a first set pitch H1 therebetween, and the first set pitch H1 is configured to prevent air flow from the air outlet 3212 from invading to a pin of the connector 2020.

For example, the first set pitch H1 may be made to range from 3mm to 10mm based on the specifications of the connector 2020 that is currently conventional.

Fig. 10 and 12 also illustrate that the spacing between the spacer 311 and the mating end of the connector 2020 is a third set spacing H3, where the third set spacing H3 satisfies that the spacer 311 can effectively shield the mating end of the connector 2020, and prevent air flow from invading into the pins of the connector 2020 through the gap between the two.

The third set pitch H3 may be designed according to a system tolerance, for example, the third set pitch H3 may be 0.5mm to 3mm.

As for the spacer 311, it may be a flat plate shape, and in some examples, the height of the spacer 311 is made the same as the height of the dummy panel of the panel portion 1, i.e., the top sides of both are made flat.

As for the air guide 321, it may be any cavity structure having a closed sidewall, and the cross-sectional shape of the air guide 321 includes, but is not limited to: regular geometric shapes such as circles, rectangles, squares, ovals, and the like, as well as irregular geometric shapes.

For the structural design of the wind guiding body 321, it is not excluded that according to the internal arrangement of the electronic device, a avoidance groove or a avoidance hole may be provided at a corresponding position of the wind guiding body 321 to prevent interference.

In some examples, as shown in fig. 6, the dust-proof portion 3 further includes a connection plate 33, the connection plate 33 being connected to the bottom side of the partition 311; the dust-proof portion 3 is connected to the bottom plate portion 2 via a connection plate 33.

One end of the connection plate 33 is connected to the bottom side of the partition 311, and the other end of the connection plate 33 extends in a direction approaching the panel portion 1, and a quick and stable connection between the dust-proof portion 3 and the bottom plate portion 2 is achieved by using the connection plate 33.

By providing the baffle 34, the dust-proof effect of the dust-proof part 3 on the connector 2020 is further improved, and fig. 13 illustrates that the interval between the baffle 34 and the adjacent plate inside the adjacent slot above the baffle is Y, and the adjacent plate may be the bottom plate part of the single plate 2011 inside the adjacent slot, or the bottom plate part 2 of the connector dust-proof part 100, or some partition boards of the electronic device.

The distance Y may be in the range of 0.3mm to 1mm to avoid intrusion of air flow from the gap above the baffle 34 into the pins of the connector 2020.

Of course, when the shutter 34 is not present, the spacing between the top side of the partition 311 and the adjacent plate inside the adjacent slot above it may be made Y, which may be the bottom plate portion of the single plate 2011 inside the adjacent slot, or the bottom plate portion 2 of the connector dust-proof member 100, or some partition of the electronic apparatus. The distance Y may be in the range of 0.3mm to 1mm to avoid intrusion of air flow from the gap above the partition 311 into the pins of the connector 2020.

In some examples, for the panel portion 1, the bottom plate portion 2, the dust-proof portion 3, and the optional positioning portion 4 included in the connector dust-proof member 100, they may be independent of each other and joined by subsequent assembly, or two or more of these components may be integral structural members, for example, the panel portion 1 and the bottom plate portion 2 may be made integral structural members and subsequently assembled with the dust-proof portion 3 and the positioning portion 4.

In some examples, for the panel portion 1, the bottom plate portion 2, the dust portion 3, and the optional positioning portion 4 included in the connector dust piece 100, their materials include, but are not limited to: plastics such as Polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (Acrylonitrile Butadiene Styrene, ABS), polypropylene (PP), polystyrene (PS), polyamide (PA), polyvinyl chloride (Polyvinyl Chloride, PVC), polyoxymethylene (POM), rubber, aluminum alloy, zinc alloy, iron alloy, and the like, or a composite thereof.

In combination with the structure of the dust-proof part 3 according to the first embodiment, when the connector dust-proof part 100 based on the dust-proof part 3 is used in the empty slot 2010 of the electronic device, the working principle thereof is as follows:

Under the air supply action of the fan module 300, air flow enters the connector dust-proof part 100 from the side surface of the panel part 1 or the electronic equipment, and the air flow entering the connector dust-proof part 100 is led out through the air guide body 321, wherein the air flow is led out through the air outlet 3212 of the air guide body 321, so that the air flow flows out from the side area of the connector 2020, and thus, the air flow is far away from the plug-in end of the connector 2020, and the plug-in end of the connector 2020 is in an extremely low wind speed area, thereby preventing dust carried by the air flow from entering the plug-in end of the connector 2020, and simultaneously, heat dissipation of other parts positioned downstream of the empty slot 2010 is not influenced.

The number of connectors 2020 in the empty slots 2010 of the electronic device may be plural, and in this case, the number of dustproof structures 31 may be the same as the number of connectors 2020, where fig. 14 illustrates that the number of dustproof structures 31 and air guiding structures 32 are plural, and the dustproof structures 31 and the air guiding structures 32 are alternately arranged in sequence.

In this case, the dust caps 312 are covered outside the respective connectors 2020, and the air guide 3220 corresponds to a side region between any adjacent two connectors 2020 so as to guide the air flow out of the side region of the connector 2020.

In some examples, as shown in fig. 16, the dust cap 312 includes a cap 3121 and a cover 3122, the cap 3121 having a first open end and a second open end arranged opposite one another, the cover 3122 connecting and sealing the first open end of the cap 3121 proximate the panel portion 1; as can be seen in fig. 17, the connector 2020 enters the cover 3121 through the second open end, and the plugging end of the connector 2020 is opposite to the cover 3122.

By mating the cover 3122 and the cover 3121, the dust cover 312 can provide a closed protection for the connector 2020, which not only can significantly enhance the dust protection effect, but also can accommodate more air duct types in the electronic device.

In some examples, the sidewalls of housing 3121 may be fully enclosed or semi-enclosed, both of which may provide effective dust protection for connector 2020.

The outer contour of the housing 3121 may be various, and the inner contour shape of the housing 3121 may be matched to the outer contour shape of the connector 2020, for example, when the outer contour of the connector 2020 is rectangular, the housing 3121 may be also designed to be rectangular.

Taking the shape of the housing 3121 as a rectangle, for example, the housing 3121 may include four sidewalls (respectively referred to as opposite upper and lower sidewalls, and opposite left and right sidewalls) connected end to end, such that the housing 3121 is cooperatively connected with the cover 3122, the dust cap 312 is formed to have a cavity feature of five sides closed and one side open (see fig. 16), thereby achieving a totally enclosed protection for the connector 2020, which is particularly advantageous for enhancing the dust-proof effect.

Alternatively, the structure of the housing 3121 may be further simplified according to at least one of the structural features of the connector 2020 and the air channel features, for example, by having the housing 3121 include only an upper side wall and a lower side wall while eliminating a left side wall and a right side wall, or by having the carrier include only a left side wall and a right side wall while eliminating an upper side wall and a lower side wall.

In some examples, as shown in fig. 14, the support 322 includes a top support plate 35 and a bottom support plate 36 connected in sequence; dust cap 312 is connected between top support plate 35 and bottom support plate 36; the air guide 3220 is formed between the top support plate 35 and the bottom support plate 36 and is located at a side of the dust cover 312.

When the dust caps 312 and the air guides 3220 are provided in a plurality of alternately arranged, a gap between two adjacent dust caps 312 may be directly used as the air guides 3220.

In some examples, the support body 322 and the dust cover 312 are manufactured by adopting an integral molding process, that is, the dust cover 3 is an integral structural member, and in this example, the protection of the connectors 2020 can be simultaneously achieved by directly molding the dust covers 312 on the structural member and forming the air guide opening 3220 between two adjacent dust covers 312.

In other examples, the support 322 and the dust cap 312 are each independent, i.e., the plurality of dust caps 312 are each independently mounted to the support 322 such that the plurality of dust caps 312 simultaneously provide protection for the plurality of connectors 2020.

The inner wall of the housing 3121 and the outer wall of the connector 2020 have a second set spacing H2 therebetween, the second set spacing H2 being configured to prevent airflow from entering the connector 2020 through the second open end of the housing 3121.

Taking the shape of the housing 3121 as a rectangle, for example, the housing 3121 may include four sidewalls (respectively referred to as opposite upper and lower sidewalls, and opposite left and right sidewalls) connected in sequence from end to end, then the interval between the upper sidewall of the housing 3121 and the corresponding upper outer wall of the connector 2020, the interval between the lower sidewall of the housing 3121 and the corresponding lower outer wall of the connector 2020, the interval between the left sidewall of the housing 3121 and the corresponding left outer wall of the connector 2020, and the interval between the right sidewall of the housing 3121 and the corresponding right outer wall of the connector 2020 may be regarded as the second set interval described above.

In some examples, the second set pitch H2 has a value in the range of 0.05mm to 1.0mm to form an elongated slit to prevent intrusion of the air flow.
