[0027] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0028] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.
[0029] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).
[0030] For some electronic equipment with harsh working environment, such as underground mine communication base stations, the use environment is often characterized by high humidity and dust. Even if the protection level of the equipment shell reaches IP54, there will still be a lot of fine dust entering the chassis during use, especially when the cover is opened for equipment maintenance, dust is more likely to enter, and the plug-in interface of the electronic connector is the most likely to be damaged by dust.
[0031] In addition, since some electronic devices currently adopt standardized and modular designs, electronic connector interfaces will have design margins and are usually not fully used during use. Dust is more likely to enter the electronic connector interfaces that are not inserted with matching plug-in modules, resulting in poor contact of the interfaces.
[0032] For example, see Figure 1 A PBC board 120 of a mine-used integrated communication base station is provided with 6 electronic connectors 100, which can be plugged with up to 6 plug-in modules. The plug-in modules are connected to the electronic connectors 100 to realize connection with functional modules such as a network interface module, a wireless WIFI module, a language gateway module, a WPLC-CPU main control module, a WPLC-IO digital module, and a WPLC-AD analog module. However, the plug-in modules are usually not fully plugged in during normal use, and some electronic connectors 100 are vacant, which are easily damaged by dust.
[0033] For ease of understanding, the electronic connector 100 or the electronic connector 100 body involved in this application can be understood as a gold finger type electronic connector 100, for example, a PCI-Z interface of Zheyang Company. Of course, this is not a limitation on the electronic connector 100, and the electronic connector 100 can also be understood as a PCI-E interface or other types of electronic connectors 100.
[0034] The electronic connector protective cover provided in the present application, through the joint action of the cover body 200 and the dust shield 300, can close and protect the plug-in interface of the electronic connector 100 when the electronic connector 100 is in an empty state, and provide an insertion port when the plug-in module is inserted into the plug-in interface of the electronic connector 100. In addition, by providing the accommodating cavity 230, it is possible to prevent the dust shield 300 from being brought into the plug-in interface of the electronic connector 100 when the plug-in module is inserted into the electronic connector 100, which helps to ensure smooth plug-in and unplugging of the plug-in module, so that the electronic connector protective cover can provide dust-proof protection for the plug-in interface of the electronic connector 100 throughout its use cycle, thereby protecting the plug-in interface of the electronic connector 100 from dust damage.
[0035] Please refer to Figure 2-4 An embodiment of the present application provides an electronic connector protective cover, including a cover body 200 and a dust shield 300 .
[0036] Please refer to Figure 1 and Figure 2 The sleeve body 200 can be understood as a collection of the basic structural framework and outline of the electronic connector protective sleeve. The sleeve body 200 has a sleeve cavity 210 and a sleeve opening 220. The sleeve cavity 210 is used to accommodate the electronic connector 100. The sleeve opening 220 is arranged on one side of the sleeve cavity 210 and communicates with the sleeve cavity 210. The sleeve opening 220 is used for the electronic connector 100 to enter the sleeve cavity 210.
[0037] Exemplarily, the sleeve 200 is roughly a rectangular parallelepiped structure, and has a sleeve cavity 210 in the sleeve 200 that is structurally compatible with the electronic connector 100. One side of the sleeve cavity 210 passes through the sleeve 200 to form a sleeve opening 220. When in use, the sleeve 200 can be sleeved on the electronic connector 100 through the sleeve opening 220.
[0038] In one embodiment, please refer to Figure 2 and Figure 3 , a protrusion 211 is provided on the cavity wall of the sleeve cavity 210 on the side away from the sleeve opening 220, and the protrusion 211 is used to accommodate the ridge 110 on one side of the electronic connector 100. Exemplarily, the protrusion 211 is a protruding cavity with a cross section that is approximately trapezoidal, and the ridge 110 of the electronic connector 100 is structurally adapted to the protrusion 211, and the material of the sleeve body 200 is an elastic material, so that the sleeve body 200 can not only be sleeved on the electronic connector 100, but also can form a chimeric structure through the protrusion 211 and the ridge 110 to prevent the sleeve body 200 from being loosened or separated from the electronic connector 100 when the plug-in module is pulled out of the electronic connector 100. The elastic material used by the sleeve body 200 in different embodiments can be any one of silicone, polyurethane and ethylene-vinyl acetate copolymer.
[0039] Please refer to Figure 1 and Figure 2 In one embodiment, the dust shield 300 is arranged on the side of the sleeve 200 away from the sleeve opening 220, and the dust shield 300 is arranged in pairs, and the two dust shields 300 in the pair each have a fixed side 310 fixed to the sleeve 200 and a cantilevered movable side 320; the dust shield 300 is made of elastic material, and the movable sides 320 of the two dust shields 300 have a closed state of natural abutment, and also have an open state separated by being squeezed by the plug-in module adapted to the electronic connector 100, and an insertion port is formed between the dust shields 300 in the open state, and the insertion port is connected to the sleeve cavity 210, so as to allow the plug-in module adapted to the electronic connector 100 to enter the sleeve cavity 210. The elastic material used by the dust shield 300 can also be any one of silicone, polyurethane and ethylene-vinyl acetate copolymer in different embodiments.
[0040] For example, a "H"-shaped gap is provided on the side of the sleeve 200 away from the sleeve opening 220, and the gap penetrates the side wall of the sleeve 200 and communicates with the sleeve cavity 210. A pair of dust shields 300 integrally provided with the sleeve 200 can be formed on both sides of the gap, and the opposite side of the two dust shields 300 is the movable side 320, and the opposite side is the fixed side 310. The movable sides 320 of the two dust shields 300 naturally abut in a natural state, and because of the use of elastic material, they can be tightly sealed to achieve a dustproof effect; they can also be pressed and pushed away by the plug-in module when the plug-in module is inserted, and automatically rebound and reset after the plug-in module is pulled out, so as to provide full dustproof protection for the electronic connector 100.
[0041] In one embodiment, please refer to Figure 2 There is also a accommodating cavity 230 between the dust shield 300 and the sleeve cavity 210. When the dust shield 300 is in an open state, the accommodating cavity 230 is used to provide a receiving space for the dust shield 300 to prevent the dust shield 300 from entering the plug-in interface of the electronic connector 100 when the plug-in module is inserted, which helps to ensure that the plug-in module can be freely plugged in and out and is not affected by the protective cover of the electronic connector.
[0042] Exemplarily, a thinning process is performed on the side of the dust shield 300 close to the sleeve cavity 210 , so that a gap is formed between the dust shield 300 and the sleeve cavity 210 , and the gap can serve as the accommodating cavity 230 .
[0043] In another embodiment, please refer to Figure 1 and Figure 2The sleeve body 200 has an insertion slot 240, which is arranged on the side of the sleeve body 200 away from the sleeve opening 220 and communicated with the sleeve cavity 210, and the fixed side 310 of the dust shield 300 is fixed to the slot wall of the insertion slot 240. Exemplarily, the fixed side 310 of the dust shield 300 is fixed to the slot wall of the insertion slot 240, and is fixed to the slot wall of the insertion slot 240 away from the sleeve cavity 210, so that the part of the insertion slot 240 between the dust shield 300 and the sleeve cavity 210 can be used as the accommodating cavity 230. The insertion slot 240 can be used as a plug-in and unplug channel for the plug-in module, and can also be used as an installation space for the dust shield 300, and the accommodating cavity 230 can also be set in the insertion slot 240.
[0044] In one embodiment, please refer to Figure 2 The thickness of the dust shield 300 gradually decreases from the fixed side 310 to the movable side 320. That is, the thickness of the movable side 320 of the dust shield 300 is thinner, which helps to reduce the stretching of the dust shield 300 when it is pressed, and further prevents the dust shield 300 from entering the plug-in interface of the electronic connector 100 when the plug-in module is inserted.
[0045] In a specific embodiment, please refer to Figure 2 The side surface of the dust shield 300 facing away from the sleeve cavity 210 is a slope 330, and the slope 330 gradually approaches the sleeve cavity 210 from the fixed side 310 to the movable side 320. In different embodiments, the slope 330 can be set to an inclined surface or an arc surface to achieve the effect of reducing the thickness of the movable side 320 of the dust shield 300. In addition, the cooperation of the slopes 330 of the two dust shields 300 also facilitates the operator to accurately locate the gap between the two dust shields 300, which helps to accurately insert the plug-in module into the plug-in interface of the electronic connector 100.
[0046] In another specific embodiment, please refer to Figure 2 , the side of the dust shield 300 close to the sleeve cavity 210 can also be set as an arched surface 340 or an inclined surface to achieve the effect of reducing the thickness of the movable side 320 of the dust shield 300. Of course, according to design and use requirements, the side of the dust shield 300 away from the sleeve cavity 210 can also be set as a slope 330, and the side of the dust shield 300 close to the sleeve cavity 210 can be set as an arched surface 340 or an inclined surface.
[0047] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4, and further includes a fixing foot 400, which is disposed on the sleeve 200 and is used to be fixed on a mounting member (such as a PBC board 120) on which the electronic connector 100 is mounted. The sleeve 200 can be fixed on the mounting member by the fixing foot 400, and the sleeve 200 is further fixed, which helps to prevent the sleeve 200 from being loosened or separated from the electronic connector 100 due to the plug-in module.
[0048] Exemplarily, the electronic connector 100 is installed on the PBC board 120, and the PBC board 120 is provided with protective cover fixing holes 121 on both sides of the electronic connector 100, and two fixing feet 400 are provided on both sides of the sleeve body 200. The two fixing feet 400 are specifically arranged on both sides of the sleeve opening 220, and the two fixing feet 400 are each clamped in a protective cover fixing hole 121 to achieve connection with the PBC board 120.
[0049] In one embodiment, please refer to Figure 3 and Figure 4 The fixing foot 400 includes a connecting portion 410 and a clamping portion 420. The connecting portion 410 is connected between the sleeve 200 and the clamping portion 420. The connecting portion 410 has a length direction. The projection of the clamping portion 420 in the length direction of the connecting portion 410 protrudes from the connecting portion 410. The materials of the connecting portion 410 and the clamping portion 420 are both elastic materials. During installation, the clamping portion 420 can be passed through the fixing hole 121 of the protective sleeve so that the clamping portion 420 is clamped on the back of the PBC board 120, which helps to improve the fixing effect of the sleeve 200. The elastic material used in the connecting portion 410 and the clamping portion 420 can be one of silicone, polyurethane and ethylene-vinyl acetate copolymer in different embodiments.
[0050] In one embodiment, please refer to Figure 1 and Figure 2 , the projections of the two opposite sides of the clamping part 420 in the length direction of the connecting part 410 protrude from the connecting part 410, so that it is convenient for the clamping part 420 to pass through the protective cover fixing hole 121, and the clamping part 420 can be clamped on the back of the PBC board 120 after passing through the protective cover fixing hole 121. In addition, in order to make it easier for the clamping part 420 to pass through the protective cover fixing hole 121, in some embodiments, a chamfer is provided on one side of the clamping part 420 away from the connecting part 410.
[0051] In one embodiment, please refer to Figure 1 and Figure 2The fixing foot 400 also includes an operating part 430, which is arranged on the side of the clamping part 420 away from the connecting part 410, and the projection of the operating part 430 in the axial direction of the connecting part 410 coincides with the projection of the connecting part 410. The arrangement of the operating part 430 makes it possible to first pass the operating part 430 through the protective cover fixing hole 121 when the clamping part 420 needs to be clamped on the back of the PBC board 120, and then pull the clamping part 420 through the protective cover fixing hole 121 by pulling the operating part 430, so as to facilitate the installation of the electronic connector protective cover.
[0052] Exemplarily, the operating part 430 and the connecting part 410 are concentrically arranged with equal diameters, and the diameters of the operating part 430 and the connecting part 410 are no larger than the diameter of the protective cover fixing hole 121 . A chamfer is provided at one end of the operating part 430 away from the clamping part 420 so that the operating part 430 can be inserted into the protective cover fixing hole 121 .
[0053] In one embodiment, please refer to Figure 1 and Figure 2 The housing 200 and the dust shield 300 are integrally provided. The housing 200 and the dust shield 300 are both made of elastic material. In different embodiments, the elastic material can be any one of silicone, polyurethane and ethylene-vinyl acetate copolymer. In addition, in some embodiments, the fixing foot 400 can also be integrally provided with the housing 200.
[0054] Exemplarily, the sleeve body 200, the dust shield 300 and the fixing foot 400 are all integrally arranged, and the materials used are all silicone materials, so that the electronic connector protective cover has the characteristics of wear resistance, wide temperature adaptability range, long life, good elasticity and low cost.
