[0047] The advantages and features of the present application can be more easily understood by those skilled in the art from the preferred embodiments of the present application described in detail below with reference to the drawings, so that the scope of protection of the present application can be more clearly defined.

[0048] In the drawings, left and right, front and back represent two horizontal directions orthogonal to each other, and up and down represent a vertical direction. The first direction is the up and down direction, the second direction is the left and right direction, and the third direction is the front and back direction.

[0049] The dustproof structure is used to protect the network module from dust and other pollutants when the network module is not engaged with the plug (not shown in the figure).

[0050] The network module includes a housing 1 provided with a socket 11, the socket 11 is opened from the end face of the housing 1 in the front and back direction, and the plug can be inserted into the socket 11. Referring to the drawings, Figure 1 The dustproof structure includes a hinge seat 2 located on one side of the socket 11 in the up and down direction and a dustproof cover 3 hinged to the hinge seat 2, the hinge seat 2 is arranged on the housing 1, and the dustproof cover 3 can be flipped up and down along the hinge seat 2 to switch between the first position and the second position, when the dustproof cover 3 is flipped to the first position, it can be fixed with the housing 1 and close the socket 11, at this time, the dustproof cover 3 plays a dustproof role. Referring to the drawings, Figure 9 When the dustproof cover 3 is flipped to the second position, the socket 11 is in an open state, at this time the plug can be inserted into the socket 11. Exemplarily, the dustproof cover 3 is configured to be flipped upward to reach the first position, at this time the hinge seat 2 is located below the socket 11.

[0051] Referring to the drawings, Figure 3 and the drawings, Figure 3 The dustproof cover 3 and the hinge seat 2 are hinged, the dustproof cover 3 includes a pressing part 33 and a cover part 32 arranged in sequence from the side away from the hinge seat 2 to the side close to the hinge seat 2, in the first position, the pressing part 33 is in interference fit with the socket 11 and closes the socket 11 together with the cover part 32. The cover part 32 includes two first side walls 3211 spaced apart in the left and right directions, the two first side walls 3211 can be at least partially embedded in the socket 11, the part of the first side wall 3211 embedded in the socket 11 is provided with a first protrusion 3211a at a position close to the pressing part 33, the first protrusion 3211a is in interference fit with the side wall of the socket 11 to keep the dustproof cover 3 in the first position.

[0052] In this embodiment, the dust cover 3 and the shell 1 are hinged, and the jack 11 is opened and closed by turning up and down. When it is necessary to prevent dust from entering the jack 11, the dust cover 3 is turned up, and the pressing part 33 and the first protrusion 3211a are used to fix the dust cover 3 and the jack 11. At this time, the pressing part 33 and the upper end surface of the jack 11 abut, and the first protrusion 3211a and the side wall of the jack 11 abut. The dust cover 3 is fixed to the jack 11 by the pressing part 33 and the first protrusion 3211a, and the stability of the dust cover 3 in the first position is improved. At this time, when the dust cover 3 is closed, it is not easy to be loosened from the jack 11 due to accidental operation (for example, no force is applied to the pressing part 33, but the shell 1 shakes and applies a slight external force to the dust cover 3), which may cause the dust cover 3 to be opened by mistake. Therefore, the dustproof effect of the dust cover 3 is greatly improved.

[0053] Furthermore, when the dust cover 3 in the first position is opened, an external force needs to be applied to the pressing part 33 to overcome the force when the first protrusion 3211a and the pressing part 33 are inserted into the jack 11. During this process, the pressing part 33 will first separate from the jack 11. After the pressing part 33 and the jack 11 are separated, the first protrusion 3211a is arranged at a position close to the pressing part 33 on the first side wall 3211, and the first protrusion 3211a can be separated from the jack 11 immediately. At this time, the dust cover 3 and the jack 11 are not clamped. When the dustproof mechanism is arranged to open the jack 11 by turning the dust cover 3 downward, no force needs to be applied at this time. Under the action of gravity, the dust cover 3 will swing to the second position. When the dustproof mechanism is arranged to open the jack 11 by turning the dust cover 3 upward, no force needs to be applied at this time. When the plug is inserted into the jack 11, the plug can directly turn the dust cover 3 upward.

[0054] The dust cover 3 further comprises a hinge part 31. The hinge part 31 is arranged on a side of the cover part 32 close to the hinge seat 2, and the hinge part 31 and the hinge seat 2 are hinged to realize the up-and-down swinging of the dust cover 3 relative to the hinge seat 2.

[0055] In an embodiment, in order to improve the convenience of operation, the pressing part 33 is arranged to be able to turn the dust cover 3 by single-finger pressing. As shown in FIG. 6, the pressing part 33 comprises a clamping part 331 and a pressing part 332. The clamping part 331 extends along the upper end surface of the cover part 32 away from the hinge seat 2 to a side away from the hinge seat 2, and the pressing part 332 extends along the outer side surface of the clamping part 331 to the outer side. The outer side surface refers to the surface of the dust cover 3 facing outward when the dust cover 3 is in the first position, and the outer side refers to the outer side of the shell 1. Figure 5

[0056] At this time, the pressing part 332 and the clamping part 331 are perpendicular, and the pressing part 332 protrudes from the clamping part 331, which is convenient for fingers to press.

[0057] In an embodiment, as shown in FIG. 7, the dust cover 3 comprises a plurality of pressing parts 33.​Figure 6 As shown, the outer side of the clamping piece 331 includes an inclined section 3311, which is located on the side of the pressing piece 332 away from the cover portion 32, and the inclined section 3311 is inclined towards the pressing piece 332 from the side away from the cover portion 32 to the side close to the cover portion 32. The outer side of the clamping piece 331 includes a vertical section, which forms an obtuse angle with the inclined section 3311, and the pressing portion 33 is arranged on the vertical section, and at this time, one end of the inclined section 3311 is in abutment with the pressing piece 332, and an obtuse angle is formed between the inclined section 3311 and the pressing piece 332.

[0058] The arrangement of the inclined section 3311 provides space for the insertion of the finger, and compared with only arranging the vertical section, the space for the finger to enter between the shell 1 and the pressing piece 332 is larger, which facilitates one-handed operation. Even if the dustproof structure is arranged in a narrow space, it is not necessary to additionally provide space for the finger to operate, and the arrangement of the inclined section 3311 on the dustproof structure can meet the operation requirements of the finger.

[0059] Referring to FIG. 1, Figure 6 As shown, the upper end surface of the clamping piece 331 is the surface of the clamping piece 331 away from the cover portion 32, and the upper end surface of the clamping piece 331 is also an inclined surface 3312 arranged in an inclined manner, and the inclination direction of the inclined surface 3312 is opposite to that of the inclined section 3311, so as to facilitate the clamping piece 331 to enter the socket 11 and abut against the upper end surface of the socket 11. Because the clamping piece 331 swings into the socket 11, the low end of the inclined upper end surface of the clamping piece 331 facilitates the entry into the socket 11, and the high end abuts against the upper end surface of the socket 11.

[0060] When the dust cover 3 is configured to be flipped upward to the second position, and the finger presses the pressing portion 33 to make the first protrusion 3211a already disengaged from the socket 11, at this time, the dust cover 3 will still have a downward flipping force under the action of its own gravity, and even if there is no external force, the pressing portion 33 and the first protrusion will not be clamped with the socket 11, but when the plug is assembled, it is still necessary to further flip the dust cover 3 upward with one hand, and hold the plug with the other hand to insert it into the socket 11, at this time, two hands are needed for operation, which brings inconvenience to the plug insertion.

[0061] Therefore, in order to overcome this problem, in an embodiment, the part of the first side wall 3211 embedded in the socket 11 is provided with a second protrusion 3211b close to the hinge seat 2, the second protrusion 3211b can abut against the end surface of the shell 1 to leave a gap between the pressing portion 33 and the socket 11 in the front-rear direction, at this time, the dust cover 3 can be limited to the third position by the second protrusion 3211b. However, when an external force is applied, the second protrusion 3211b can enter the socket 11 under the action of the external force and be in interference connection with the side wall of the socket 11 to make the dust cover 3 maintain in the first position.

[0062] The gap does not need to be too large, generally 2mm-3mm, at which time the plug is conveniently flipped upward to flip the dust cover 3, realizing single-handed plug insertion.

[0063] In this embodiment, a second protrusion 3211b is added, and the second protrusion 3211b is arranged at a position of the first side wall 3211 close to the hinge portion 31. At this time, when the dust cover 3 is flipped, the second protrusion 3211b first abuts against the end face of the shell 1. In this way, without external force, the dust cover 3 is limited from continuing to swing, and the pressing portion 33 and the socket 11 are not attached. The pressing portion 33 and the socket 11 have a gap in the front-rear direction. At this time, as long as the plug is held and pushed upward to flip the dust cover 3, the dust cover 3 can be flipped upward, and the plug can be inserted into the socket 11 by one hand, which is convenient to operate. Meanwhile, when the dust cover 3 is in the first position, the second protrusion 3211b can also be in interference fit with the socket 11 to limit the dust cover 3 in the first position, thereby improving the stability of the dust cover 3 when closing the socket 11.

[0064] Referring to Figs. 1 and 2, Figure 4 and Figs. 3 and 4, Figure 8 As shown, the vertical distance h1 between the mutually distal ends of the second protrusions 3211b on the two first side walls 3211 in the left-right direction is slightly greater than the distance h2 of the corresponding positions of the socket 11 in the left-right direction. In this way, when the second protrusions 3211b abut against the end face of the shell 1, without external force, the second protrusions 3211b do not directly enter the socket 11 but abut against the end face of the shell 1 to play a limiting role. Meanwhile, because of the elasticity of the second protrusions 3211b, under external force, the second protrusions 3211b can be extruded to deform into the socket 11 and abut against the side wall of the socket 11 to realize interference fit, thereby further increasing the stability of the dust cover 3 when in the first position. Slightly greater means that the difference between h1 and h2 is not more than 1.5mm.

[0065] One second protrusion 3211b and one first protrusion 3211a are arranged on each of the two first side walls 3211, that is, the first protrusions 3211a and the second protrusions 3211b are both in pairs, the two second protrusions 3211b are symmetrically arranged, and the two first protrusions 3211a are symmetrically arranged. The first protrusions 3211a and the second protrusions 3211b are located in the same plane, that is, the first protrusions 3211a and the second protrusions 3211b are not staggered in the front-rear direction when in the first position, and the first protrusions 3211a and the second protrusions 3211b are not staggered in the thickness direction of the cover portion, so that when the second protrusions 3211b abut against the shell 1, the first protrusions 3211a have not yet contacted the shell 1.

[0066] In one embodiment, the first protrusion 3211a and the second protrusion 3211b may also be staggered in the thickness direction, but the distance between the two staggered needs to be guaranteed. When the second protrusion 3211b abuts against the housing 1, there is still a gap between the first protrusion 3211a and the socket 11 in the front-back direction.

[0067] Multiple second protrusions 3211b and multiple first protrusions 3211a may also be provided on the first sidewall 3211.

[0068] In one embodiment, the two sidewalls of the socket 11 are arc-shaped structures 111 near their openings. The arc-shaped structures 111 guide the dust cover 3, facilitating the entry of the first protrusion 3211a and the second protrusion 3211b on the dust cover 3 into the socket 11.

[0069] In one embodiment, the cover portion 32 and the pressing portion 33 together form a contoured part with the same shape as the socket 11, thereby improving the dustproof effect when the socket 11 is closed.

[0070] In one embodiment, the cover portion 32 includes an insert 321 and a cover 322 disposed along the thickness direction. The insert 321 can be embedded into the socket 11, and the cover 322 is located outside the insert 321 and can cover the socket 11. In this case, the cover portion 32 is configured as a double-layer structure in the thickness direction. The insert 321 closes the socket 11, and the cover 322 covers the socket 11, providing double dust protection for the socket 11 and improving the dust protection effect.

[0071] The first protrusion 3211a and the second protrusion 3211b are both provided on the insert 321. At this time, the first protrusion 3211a and the second protrusion 3211b can be embedded into the socket 11 and abut against the side wall of the socket 11 to achieve interference fixation.

[0072] The area of ​​the cover 322 is larger than the area of ​​the insert 321. The sidewall of the socket 11 includes a stepped portion with a stepped structure, and both the cover 322 and the insert 321 have the same stepped structure at positions corresponding to the stepped portion. This contoured structure of the cover 32 provides a good sealing effect for the socket 11, greatly improving the dustproof effect.

[0073] In one embodiment, see Appendix Figure 3 As shown, the outer surface 32a of the cover includes a planar segment and an arc segment, wherein the arc segment is located near the hinge 31, and the arc segment achieves a smooth transition from the planar segment to the hinge 31.

[0074] In one embodiment, see Appendix Figure 5As shown, the outer side surface 32a of the cover portion is inwardly recessed at the portion close to the hinge portion 31 to form a stepped structure. At this time, the cover portion 32 and the hinge portion 31 are no longer smoothly transitioned, but the outer side surface 32a of the cover portion is provided as a stepped structure. When the network module is fixed on the distribution frame, the outer side surface 32a of the cover portion of this structure, through the inwardly recessed portion, gives way to the distribution frame for mounting the shell 1, ensures that the dust cover 3 does not interfere with the distribution frame when it swings to the second position, and the angle between the dust cover 3 and the opening of the socket 11 in the second position is not less than 90°, facilitating the insertion of the plug.

[0075] Referring to the accompanying drawings Figure 7 As shown, the hinge seat 2 includes a slot 21 vertically arranged and communicated with the socket 11, and the shell 1 is provided with a limiting groove 22 communicated with the slot 21, and the slot 21 is arranged along the left-right direction. Referring to the accompanying drawings Figure 2 As shown, the hinge portion 31 includes an elastic arm 311 extending along the lower end surface of the cover portion 32 towards the side away from the pressing portion 33, and the side of the elastic arm 311 away from the cover portion 32 is provided with a hinge rod 312 which can be inserted into and limited in the limiting groove 22, at this time the dust cover 3 and the shell 1 are hingedly connected and can rotate around the hinge rod 312.

[0076] The slots 21 are arranged in the left-right direction and are spaced apart, and the two slots 21 are not communicated with each other. The elastic arm 311 is arranged corresponding to the slot 21, and the slot 21 can deform the elastic arm 311 by extruding the elastic arm 311 through the hinge rod 312, so that the two elastic arms 311 are close to each other, and when the hinge rod 312 is aligned with the fixing groove, the elastic arm 311 is reset by its own elasticity, and the hinge rod 312 is inserted into the limiting groove. Through this structure, the hinge portion 31 is convenient for processing and assembly.

[0077] In one embodiment, the hinge rod 312 is perpendicular to the elastic arm 311, and the hinge rod 312 includes a first inclined surface 3121, and the side wall of the slot 21 has a second inclined surface 211 matched with the first inclined surface 3121, and during the process of inserting the hinge portion 31 into the hinge seat 2, the two inclined surfaces match with each other, at this time the width of the slot 21 does not need to be too large, and the deformation requirement of the elastic arm 311 can also be met.

[0078] The dust cover 3 is assembled with the hinge seat 2 in the second position, at this time the first inclined surface 3121 and the second inclined surface 211 abut, and the dust cover 3 is pushed in the front-back direction, the elastic arm 311 deforms at the portion close to the limiting groove and resets by its own elasticity after the hinge rod 312 and the slot 21 are aligned, so as to insert the hinge rod 312 into the slot 21, and realize the connection of the hinge portion 31 and the hinge seat 2.

[0079] The slot 21 has a U-shaped structure. The upper end of the slot 21 is directly connected to the socket 11. The bottom wall of the slot 21 acts as a limit. When the spring arm 311 abuts against the bottom wall of the slot 21, the dust cover 3 can no longer swing. The dust cover 3 is in the second position. At this time, the opening of the socket 11 is open, which makes it easy to insert the plug into the socket 11.

[0080] In one embodiment, the dust cover 3 is an integrally molded injection molded part. The injection molding process of the dust cover 3 is convenient, forming an integral structure with high stability. The dust cover 3 utilizes the elasticity of plastic to achieve interference fit and separation between the dust cover 3 and the opening, and is easy to assemble with the hinge seat 2.

[0081] In this embodiment, the dustproof structure features a pressing part 33 that allows for easy application of force with a single finger, facilitating the flipping of the dustproof cover 3. Combined with the first protrusion 3211a, this enhances the fixation between the dustproof cover 3 and the socket 11, thereby improving the dustproof effect. The added second protrusion 3211b, on the one hand, improves the fixation between the dustproof cover 3 and the socket 11 in the first position; on the other hand, the second protrusion 3211b can limit the swing distance of the dustproof cover 3 when no external force is applied, leaving a gap between the pressing part 33 and the socket 11, facilitating one-handed insertion of the plug.

[0082] In one embodiment, see Appendix Figure 10 As shown, a network module in this embodiment includes a housing 1. The housing 1 has inwardly opened sockets 11 on both end faces in the front-rear direction. The aforementioned hinge seat 2 and the aforementioned dust cover 3 are provided below the socket 11 and hinged to the hinge seat 2.
