Description

Technical Field

[0001] This invention relates to the field of electronic equipment protection technology, and in particular to a dustproof device for the interface of electronic communication equipment. Background Technology

[0002] The connection interfaces of existing electronic communication equipment are often directly exposed to the environment when not in use, making it easy for dust to accumulate inside the interfaces, causing poor contact or equipment malfunction. Although some interfaces are equipped with dust covers or baffles, the interfaces are still briefly exposed during the opening and closing of the covering structure, allowing dust to enter. Furthermore, when the cables are kept connected for extended periods, it is difficult to completely prevent dust from seeping into the gaps between the cables and the interfaces, leading to malfunctions caused by dust accumulation after prolonged use. In addition, some existing dustproof methods are inconvenient to operate and cannot simultaneously address dust prevention during insertion and removal and sealing during long-term connection. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that dust easily enters the interface dustproof structure during opening and closing, and dust enters from the gaps during long-term connection, in order to propose a dustproof device for the interface of electronic communication equipment.

The clamping part is slidably disposed on the protruding end of the moving device toward the device interface and is used to clamp the connector of the wire. The drive unit is located on the housing at the position corresponding to the device interface. It is used to push the clamping part to move towards the interface and insert the connector into the interface when the clamping part moves with the moving device to the device interface side.

[0005] In some embodiments, the housing is further provided with a wire groove for the wire connected to the connector to pass through; the wire groove is connected to the inlet.

[0006] In some embodiments, a dustproof structure is provided at the wire trough; the dustproof structure includes two flexible dustproof components disposed on opposite sides of the wire trough, the two flexible dustproof components are in contact with each other in their natural state, and can generate elastic deformation to cover the wire when the wire passes through.

[0007] In some embodiments, the dustproof structure includes two dustproof strips, which are fixed to the two side walls of the trough along the extension direction of the trough, and the opposite sides of the two dustproof strips abut against each other in their natural state.

[0008] In some embodiments, the dustproof structure further includes two brushes, which are fixed to the two side walls of the groove along the extension direction of the groove, and the bristles of the two brushes are arranged alternately.

[0009] In some embodiments, the moving device includes a connecting rod and a sliding groove; a through hole is provided on the housing on the side opposite to the inlet, and the connecting rod slides through the through hole; the sliding groove is fixedly disposed at one end of the connecting rod extending out of the housing; the clamping part is slidably disposed in the sliding groove and can slide in a direction close to or away from the device interface.

[0010] In some embodiments, the device further includes an end cap, which is detachably connected to the through hole of the housing and has a sliding hole through which the connecting rod slides.

[0011] In some embodiments, the clamping part includes a slider, two clamping arms, and a reset member; the slider is slidably fitted in a sliding groove; the two clamping arms are respectively hinged to both sides of the slider, and a gap for clamping the connector is formed between the two clamping arms; the reset member is connected to the clamping arms to drive the front ends of the two clamping arms to move closer to each other.

[0013] In some embodiments, the slider has a mating groove on the side facing the slide rod, and the slide rod has an end plate at its abutting end; when the slider moves with the moving device to the device interface side, the end plate is embedded in the mating groove; pushing and pulling the slide rod can drive the slider to reciprocate along the sliding groove. Compared with the prior art, the present invention provides a dustproof device for the interface of electronic communication equipment, which has the following beneficial effects.

[0014] 1. A dustproof device for an electronic communication equipment interface according to the present invention, by means of a housing covering the outside of the interface, a retractable movable device, and a clamping part slidably disposed on the movable device, the insertion and removal of the connector is carried out under the cover of the housing; when the movable device is retracted, the inside of the housing can be kept relatively closed, effectively shortening the exposure time of the interface and reducing the possibility of dust entering the interface during the insertion and removal process. 2. The present invention provides a dustproof device for an interface of an electronic communication device. By setting a dustproof structure consisting of two flexible dustproof components at the wire groove, the flexible dustproof components undergo elastic deformation and wrap around the wire when the wire passes through, thus filling the gap between the wire and the wire groove. In this way, even when the device is connected to the wire for a long time, it can still continuously prevent dust from entering the housing from the wire groove, solving the problem of long-term dust ingress into the connection gap. Furthermore, by setting the housing as a buffer space, it prevents dust from directly contacting the interface. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1-8This invention provides a dustproof device for an interface of an electronic communication device. Its core concept is to construct a relatively closed protective space by using a shell 1 that covers the outside of the device interface. The insertion and removal of the connector are completed inside the shell 1 through the cooperation of a retractable moving device 2 and an independently sliding clamping part 205, thereby greatly shortening the exposure time of the interface during operation. At the same time, a dustproof structure that can elastically deform and tightly wrap the wire is set on the path through which the wire passes, so that even under the condition of maintaining the wire connection for a long time, dust cannot enter the interior of the interface from the gaps in the wire groove 101.

[0026] Specifically, the dustproof device mainly consists of a housing 1, a moving device 2, a clamping part 205, and a driving part 3. The housing 1 is used to fix the interface of the electronic communication equipment. It has a hollow cavity inside to accommodate the interface and connector. The rear side of the housing 1 near the interface is open, so that the opening covers the outside of the interface, which is used to completely cover the interface inside the housing 1 and prevent the equipment interface from directly contacting the external environment. A cable inlet 102 is provided on one side of the housing 1. The cable inlet 102 serves as a channel for the moving device 2 to carry the connector and also for the cable connected to the connector to enter the housing 1. The cable inlet 102 is preferably located at the bottom of the housing 1, so that dust is difficult to move upward from the bottom of the housing 1 and enter the housing 1 under the action of gravity. The movable device 2 is slidably installed inside the housing 1 and can extend or retract vertically at the inlet 102. A clamping part 205 is slidably provided on the protruding end facing the device interface. The clamping part 205 is used to clamp the connector of the wire, and can reciprocate relative to the movable device 2 in a direction closer to or further away from the device interface. The driving part 3 is located on the front side wall of the housing 1 directly opposite the device interface. When the movable device 2 moves the clamping part 205 to the side aligned with the device interface, the driving part 3 can form a separable transmission connection with the clamping part 205, thereby pushing the clamping part 205, along with the connector, to accurately insert into the device interface or pull it out of the interface, thus realizing the connection and disconnection of the connector.

[0027] like Figure 2 As shown, in one embodiment, the housing 1 is generally rectangular, with its bottom side open as a cable inlet 102. The rear opening of the housing 1 faces the side of the device interface. A cable groove 101 connecting the inner and outer sides of the housing 1 is also provided on the side of the housing 1 away from the device interface. One end of the cable groove 101 is connected to the cable inlet 102, and the other end extends to the opposite side of the device interface. When the connector is placed inside the housing 1, it allows the cable at the end of the connector to pass through. The extension direction of the cable groove 101 is perpendicular to the insertion / removal direction of the connector, so that the cable can be smoothly led out from the front of the housing 1 without excessive bending.

[0028] Specifically, to further prevent dust from entering the housing 1 from the inlet 102, a sealing door 103 is provided at the inlet 102 that can be opened and closed. Preferably, there are two sealing doors 103, which are respectively hinged to the two sides of the inlet 102. At the same time, a reset member is also provided at the hinge of the sealing door 103. When the clamping part 205 extends from the inlet 102, the clamping part 205 pushes the sealing door 103 outward to open the inlet 102. When the clamping part 205 retracts into the housing 1 and the sealing door 103 is in a free state, the reset member drives the sealing door 103 to abut against the edge of the inlet 102, so that the adjacent edges of the two sealing doors 103 move closer to each other to close the inlet 102.

[0029] like Figure 5 As shown, in one embodiment, a dustproof structure is provided on the inner wall of the housing 1 at the wire groove 101. This dustproof structure includes two flexible dustproof components disposed on both sides of the wire groove 101. In a preferred implementation, the flexible dustproof component is a dustproof strip 104 arranged along the extension direction of the groove wall, preferably made of elastic materials such as rubber or silicone. In its natural state, the opposite sides of the two dustproof strips 104 abut against each other, sealing the inner channel of the wire groove 101, preventing external dust from entering the housing 1. When the wire passes through the wire groove 101, it squeezes between the two dustproof strips 104. The dustproof strips 104 are compressed and undergo elastic deformation, opening to both sides. Simultaneously, they elastically and tightly wrap around the outer periphery of the wire, ensuring that the channel of the wire groove 101 is essentially filled by the wire and the flexible dustproof component, leaving no gaps for dust to pass through. To further enhance the dustproof effect, the dustproof structure may also include two brushes 105. The two brushes 105 are fixed to the inner walls of the housing 1 on both sides of the wire groove 101 along its extension direction, with the bristles of the two brushes 105 arranged in an alternating pattern. The bristles of the brushes 105 are fine and soft. When the wire passes through, the bristles bend and fill the smaller gaps between the wire and the groove wall, providing multiple sealing effects. Furthermore, when the wire is dragged, the bristles can scrape off dust adhering to the wire surface, achieving a self-cleaning effect. Thus, whether the wire is in a stationary connected state or moving during insertion and removal, the wire groove 101 maintains excellent dustproof capability, preventing dust from entering the housing 1 and reaching the interface area through the wire groove 101.

[0030] like Figure 6 and 7As shown, in one embodiment, the moving device 2 is used to move the clamping part 205 holding the connector from inside the housing 1 to the side of the device interface. It mainly consists of a connecting rod 202 and a sliding groove 204. A through hole is provided on the side wall of the housing 1 opposite to the inlet 102. The connecting rod 202 slides through the through hole. The end of the connecting rod 202 outside the housing 1 is provided with an operating end 203 for the user to push and pull. The end of the connecting rod 202 extending into the housing 1 is fixedly connected to the sliding groove 204. The sliding groove 204 is an n-shaped groove with a guide slide inside. The extension direction of the slide is perpendicular to the axis of the connecting rod 202, so that the clamping part 205 can slide in the insertion and removal direction. When the connecting rod 202 slides along the through hole, the sliding groove 204 moves as a whole, causing the clamping part 205 to move closer to or away from the device interface.

[0031] Specifically, to facilitate the disassembly of the mobile device 2 and allow for the replacement of different types of clamping parts 205 to adapt to different equipment interfaces, as well as to protect the sealing of the through hole, an end cap 201 can be detachably installed at the location of the through hole in the housing 1. The end cap 201 has a central sliding hole through which the connecting rod 202 slides. The end cap 201 covers the through hole, and a seal is provided between the sliding hole of the end cap 201 and the connecting rod 202 to effectively prevent dust from seeping into the housing 1 from the assembly gap of the mobile device 2. To fix the relative position of the mobile device 2, magnetic attraction devices are provided on the contact surfaces of the end cap 201 and the sliding groove 204. When the sliding groove 204 moves with the connecting rod 202 to the equipment interface side, the top surface of the sliding groove 204 contacts the bottom surface of the end cap 201 and completes the magnetic attraction fixation.

[0032] Specifically, in order to prevent the connecting rod 202 from rotating and shifting during sliding, the connecting rod 202 is preferably rectangular columnar, and the sliding hole of the end cap 201 is set as a rectangular hole so that the connecting rod 202 can only move axially when sliding along the sliding hole.

[0033] like Figure 7As shown, in one embodiment, the clamping part 205 specifically includes a slider 2051, two clamping arms 2052, and a reset member. The slider 2051 is slidably engaged within the slide rail of the sliding groove 204, and can move smoothly in the direction of approaching or moving away from the device interface. Preferably, the inner sidewall of the slide rail of the sliding groove 204 is provided with a guide strip, and a guide groove is provided on the corresponding sidewall of the slider 2051, so that the guide strip is slidably disposed in the guide groove, preventing the slider 2051 from deviating when moving, and when the slider 2051 slides along the slide rail of the sliding groove 204, its sliding limit position is always kept within the slide rail, preventing the slider 2051 from disengaging from the slide rail. The two clamping arms 2052 are respectively mounted on both sides of the slider 2051 through hinge shafts, and the front ends of the two clamping arms 2052 extend forward and bend towards each other to form a gap for clamping the connector. The reset element provides an elastic driving force to bring the front ends of the clamping arms 2052 closer together. The reset element is preferably a torsion spring, mounted on the hinge shaft of the clamping arms 2052. The two ends of the torsion spring act on the two clamping arms 2052 and the slider 2051, respectively. In its natural state, the elastic force of the torsion spring causes the front ends of the two clamping arms 2052 to tend to abut each other. Specifically, to facilitate connector installation, the front end of the clamping arm 2052 is designed in an arc shape, forming a guide surface. When the front ends of the two clamping arms 2052 abut against each other, the connector can be inserted between the arc-shaped front ends, allowing the connector to abut against the arc-shaped guide surface. This pushes the two clamping arms 2052 outward, so that the connector is subjected to a corresponding force, completing the clamping or disengaging action. When the connector needs to be installed, the operator pinches the connector and presses it into the gap between the clamping arms 2052. The restoring force of the torsion spring drives the front end of the clamping arm 2052 to reliably clamp the connector, thereby fixing the connector to the clamping part 205. Since the clamping arm 2052 can swing around the hinge axis, it can adapt to connectors with certain differences in shape and size, ensuring stable clamping.

[0034] Specifically, to prevent the connector from slipping between the clamping arms 2052 when the drive unit 3 pushes the clamping part 205 to move for connector insertion, a baffle 2054 is provided on the side of the slider 2051 away from the device interface. The baffle 2054 is semi-circular with a notch in the center for the wire to pass through. Since the diameter of a typical connector is larger than the diameter of the wire, the connector is clamped inside the clamping arms 2052, and the baffle 2054 is placed at the end of the connector closest to the wire, with the wire passing through the notch. When the drive unit 3 pushes the clamping part 205 to move for connector insertion, the baffle 2054 moves against one end of the connector, reducing the risk of the connector slipping between the clamping arms 2052.

[0035] like Figure 3-7As shown, in one embodiment, the drive unit 3 is used to perform insertion and extraction drive actions after the clamping unit 205 reaches the interface side. The drive unit 3 includes a slide rod 301. A mounting hole 106 is provided on the side wall of the housing 1 facing the device interface. A sliding sleeve 304 is fixedly installed at the mounting hole 106, and the slide rod 301 slides through the sliding sleeve 304. An end plate 303 is provided at the end of the slide rod 301 that extends into the housing 1. The lateral dimension of the end plate 303 is larger than that of the slide rod 301 body. A handle 302 is provided at the end of the slide rod 301 that extends out of the housing 1 for easy gripping and operation by the operator. The sliding sleeve 304 provides support and guidance for the slide rod 301. A sealing element can also be provided between the slide rod 301 and the sliding sleeve 304 to ensure the dustproof performance of the drive unit 3 mounting location.

[0036] Specifically, in order to enable the drive unit 3 to move the clamping unit 205 back and forth, a docking groove 2053 is provided on the side of the slider 2051 of the clamping unit 205 facing the slide rod 301. The docking groove 2053 has an opening facing the through hole at the top of the housing 1, and a clearance groove connected to the opening is provided on the side near the slide rod 301 for the slide rod 301 to enter. The interior of the docking groove 2053 is a groove structure with a width slightly larger than that of the end plate 303. When the moving device 2 pushes the sliding groove 204 together with the slider 2051 to a predetermined position, so that the slider 2051 is at the device interface, the end plate 303 at the end of the slide rod 301 can just fall into the docking groove 2053 of the slider 2051, and at the same time the slide rod 301 enters the clearance groove. At this time, the end plate 303 and the docking groove 2053 form an embedded connection. In this state, pushing the slide bar 301 towards the housing 1 causes the slide bar 301 to push the slider 2051 along the sliding groove 204 towards the device interface via the end plate 303. The connector held by the clamping arm 2052 is then smoothly pushed into the interface, achieving electrical connection. To disconnect, pull the slide bar 301 outwards. The slide bar 301, through the embedded connection formed by the end plate 303 and the mating groove 2053, pulls the slider 2051 to slide in the opposite direction, removing the connector from the device interface. Throughout the entire insertion and removal process, the interface only experiences relative movement for a very short period when the slider 2051 drives the connector to insert or remove. The interface area remains under the protection of the housing 1, making it difficult for external dust to enter. This fundamentally avoids the drawback of traditional flip-top dustproof structures where a large amount of dust enters the interface during opening and closing.

[0037] Specifically, in order to ensure that after the connector is pulled outward, the slider 2051 can be stably and accurately positioned in its original position within the slide rail of the sliding groove 204, such as... Figure 8As shown, a contact platform 305 is also provided on the slide rod 301. It is located on the side of the end plate 303 near the slide rod 301. Its diameter is smaller than that of the end plate 303 and larger than that of the slide rod 301. This allows the contact platform 305 to be embedded in the clearance groove of the mating groove 2053. When the joint is pulled outward, the slide rod 301 moves outward accordingly, so that one end of the contact platform 305 abuts against the sliding sleeve 304 and blocks the slider 2051 from continuing to move, thereby completing the precise positioning of the slider 2051.

[0038] The present invention discloses a dustproof device for an interface of an electronic communication device, the working principle of which is as follows: In non-use mode, the moving device 2 retracts into the housing 1, and the connector held by the clamping part 205 is also located inside the housing 1. The wire passes through the wire groove 101 and is tightly wrapped by the dustproof strip 104 and the brush 105. The wire inlet 102 of the housing 1 and the dustproof structure at the wire groove 101 together form a closed barrier, keeping the equipment interface in a dust-free isolated environment. When it is necessary to connect the equipment, the operator pushes the connecting rod 202 to extend the moving device 2. The clamping part 205 carries the connector to the side of the equipment interface. At the same time, the mating groove 2053 on the slider 2051 automatically aligns and engages with the end plate 303 at the end of the slide rod 301. Then, the slide rod 301 is pushed, and the slide rod 301 drives the slider 2051 and the connector to be smoothly inserted into the equipment interface along the sliding groove 204 to complete the wiring connection. During this process, the wire moves along the wire groove 101, and the dustproof strip 104 and the brush 105 are always elastically deformed and wrapped around the wire, preventing dust from entering the gap due to the dragging of the wire.

[0039] When disconnection is required, pull the cable outward to disengage the connector from the interface. Then, press down on the connecting rod 202 to move the moving device 2 downward, separating the end plate 303 from the mating groove 2053. The clamping part 205 and the connector extend out of the housing 1, allowing the cable and connector to be removed. Afterward, retract the connecting rod 202 into the housing 1, and the sealing door 103 closes the inlet 102, restoring the dustproof structure to a sealed state. The entire insertion, removal, and connection process is carried out under the protection of the housing 1, making operation convenient and smooth. This effectively solves the problems of easy dust ingress when opening and closing the interface dustproof structure, dust seepage through gaps during long-term connection, and inconvenience in operation in the prior art, significantly improving the dustproof reliability and durability of electronic communication equipment interfaces.
