Description

Technical Field

[0001] This utility model relates to the field of communication management hub technology, and in particular to a multi-master communication management hub with interface protection function. Background Technology

[0002] Hubs are purely hardware-based network devices and essentially lack the "intelligent memory" and "learning" capabilities of switches. They also lack the MAC address table found in switches, so they send data in a non-targeted manner, using a broadcast method. That is, when a hub wants to send data to a node, it doesn't send the data directly to the destination node, but rather sends the data packet to all nodes connected to the hub, as shown in the diagram—simple and clear.

[0003] The dust cover of the hub interface provides dual protection through a precisely matched physical shielding and sealing design: it can block foreign objects such as dust and debris, preventing contact oxidation or poor contact; and it can reduce moisture and liquid intrusion through edge sealing, reducing the risk of short circuits or corrosion.

[0004] While the aforementioned technologies achieve dust protection for hub interfaces, the dustproof design of the dust cover often causes significant operational inconvenience when inserting interface devices in actual use. Therefore, a multi-master communication management hub with interface protection function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-master station communication management hub with interface protection function, which aims to solve the problem that the dustproof design of the dust cover in the prior art often brings obvious inconvenience when inserting interface devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-master station communication management hub with interface protection function, including a hub, a support plate fixedly connected to the interface of the hub, a dustproof component inside the support plate, and a heat dissipation support component at the bottom of the hub; The dustproof component includes a movable block, the outer wall of which is fixedly connected to a partition, the inside of which a slot is formed, and the inside of which an arc-shaped groove is formed, and the outer wall of the movable block is elastically connected to the inside of the arc-shaped groove by a spring.

[0007] As a further description of the above technical solution: One end of the spring is fixedly connected to the inside of the arc-shaped groove, and the other end of the spring is fixedly connected to the outer wall of the moving block.

[0008] As a further description of the above technical solution: The movable blocks are provided in multiple sets, and the multiple sets of movable blocks are distributed in a ring along the center of the slot.

[0009] As a further description of the above technical solution: The outer wall of the movable block is slidably connected to the inside of the arc-shaped groove.

[0010] As a further description of the above technical solution: The heat dissipation support assembly includes a bracket, the inner wall of which has a slot, a support block is rotatably connected inside the bracket, the outer wall of which has a groove, and a locking block is elastically connected inside the groove through a return spring.

[0011] As a further description of the above technical solution: One end of the reset spring is fixedly connected to the inside of the groove, and the other end of the reset spring is fixedly connected to the rear wall of the block.

[0012] As a further description of the above technical solution: The outer wall of the card block is engaged with the inside of the card slot, and the top of the card slot is fixedly connected to the bottom of the support plate.

[0013] As a further description of the above technical solution: The card blocks are provided in two sets, and the two sets of card blocks are distributed in a mirror image along the central axis of the support block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a spring, a moving block, and a partition, the data cable is inserted into the interface. The moving block and the partition retract under the action of the spring, which partially blocks the interface when it is not in use, thereby reducing the entry of impurities and avoiding poor contact, short circuits, or performance degradation.

[0015] 2. In this utility model, by setting a reset spring, a locking block, and a locking groove, the support plate is manually rotated. Under the action of external force, the locking block disengages from the locking groove, thereby supporting the rear end of the hub and creating a certain gap between the rear end of the hub and the placement plane, thus improving heat dissipation performance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model is provided: a multi-master station communication management hub with interface protection function, including a hub 1. A support plate 2 is fixedly connected to the interface of the hub 1, which provides a stable installation base for the subsequent dustproof component 3 and enhances the stability of the overall structure. The support plate 2 is provided with a dustproof component 3 that can effectively block external dust from entering the interface of the hub 1 and avoid dust accumulation affecting the normal use of the interface. A heat dissipation support component 4 is provided at the bottom of the hub 1. The dustproof component 3 includes a movable block 31, with a partition 32 fixedly connected to the outer wall of the movable block 31. The support plate 2 has a slot 34 inside that provides a channel for the insertion of the interface device. The slot 34 has an arc-shaped groove 35 inside that provides a trajectory for the sliding of the movable block 31. The outer wall of the movable block 31 is elastically connected to the inside of the arc-shaped groove 35 by a spring 33. The spring 33 provides elastic restoring force to the movable block 31. One end of the spring 33 is fixedly connected to the inside of the arc-shaped groove 35, and the other end of the spring 33 is fixedly connected to the outer wall of the movable block 31. When no interface device is inserted, multiple sets of movable blocks 31 converge towards the center of the slot 34 along the arc-shaped groove 35 under the elastic action of the spring 33, causing the partition 32 fixed to the outer wall to stick together, thereby sealing the slot 34 and achieving dustproof protection for the interface of the hub 1. When an interface device needs to be inserted, the insertion force of the device will push the moving block 31 to overcome the elastic force of the spring 33 and slide along the arc groove 35 in a direction away from the center of the slot 34, so that the partition 32 separates from each other and the slot 34 opens, making it easier for the device to be inserted smoothly.

[0020] Reference Figures 2-4Multiple sets of movable blocks 31 are provided, and these sets of movable blocks 31 are distributed in a ring along the center of the slot 34. The outer wall of the movable block 31 is slidably connected to the inside of the arc-shaped slot 35. The heat dissipation assembly 4 includes a bracket 41, which is the basic frame for supporting the heat dissipation assembly 4 and serves to connect and support other components. The inner wall of the bracket 41 has a slot 42, which cooperates with the locking block 45 to fix the support block 43. The support block 43 is rotatably connected inside the bracket 41. The outer wall of the support block 43 has a groove 46 that provides installation space for the locking block 45 and the return spring 44. The locking block 45 is elastically connected inside the groove 46 through the return spring 44, and one end of the return spring 44 is fixedly connected to the groove 46. Inside, the other end of the return spring 44 is fixedly connected to the rear wall of the locking block 45. The outer wall of the locking block 45 is engaged with the inside of the slot 42. The top of the slot 42 is fixedly connected to the bottom of the support plate 2. There are two sets of locking blocks 45, which are distributed in a mirror image along the central axis of the support block 43. The bracket 41 is fixed to the bottom of the support plate 2 through the slot 42. When the support block 43 is rotated, the locking block 45 is squeezed by the inner wall of the slot 42, which will compress the return spring 44 and retract into the groove 46. This releases the engagement between the locking block 45 and the slot 42. When the support block 43 is retracted, the locking block 45 is rotated back. The locking block 45 will pop out under the elastic force of the return spring 44 and engage in the corresponding slot 42, thus fixing the support block 43.

[0021] Working principle: When in use, without the interface device inserted, multiple sets of moving blocks 31, under the elastic action of spring 33, converge along the arc groove 35 toward the center of the slot 34, causing the partition 32 fixed on the outer wall to stick together, thereby sealing the slot 34 and achieving dust protection for the hub 1 interface. When an interface device needs to be inserted, the insertion force of the device will push the moving block 31 to overcome the elastic force of the spring 33 and slide along the arc groove 35 away from the center of the slot 34, so that the partition 32 separates from each other and the slot 34 opens, making it easy for the device to be inserted smoothly. The bracket 41 is fixed to the bottom of the support plate 2 through the slot 42. When the support block 43 is rotated, the locking block 45 is squeezed by the inner wall of the slot 42, which will compress the return spring 44 and retract into the groove 46; thus releasing the locking of the locking block 45 and the slot 42. When the support block 43 is retracted, the locking block 45 is rotated back, and the locking block 45 will pop out under the elastic force of the return spring 44 and lock into the corresponding slot 42, thereby fixing the support block 43.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
