Description

Technical Field

[0001] This utility model relates to the field of switch housing technology, specifically a multi-layer protective switch housing for high humidity environments. Background Technology

[0002] With the rapid development of information technology and the popularization of network equipment, switches, as the core equipment for data exchange, are widely used in data centers, communication base stations, industrial environments and other high-requirement places. As electronic devices, switches contain complex circuits and precision electronic components, and are highly sensitive to the external environment. Especially in harsh environments such as vibration, high humidity and dust, the equipment is prone to failure, which affects the normal operation of the network.

[0003] For example, patent CN212752285U discloses a switch housing structure. A heat-conducting sheet absorbs and transfers the heat generated by the switch chip during operation. Fins absorb and transfer the heat from the heat-conducting sheet. Coolant inside the fins improves the efficiency of heat absorption and transfer. A heat sink absorbs the heat from the fins. The heat-conducting sheet, fins, and heat sink are in contact with the air, transferring their own heat to the air. This passive cooling method avoids heat buildup on the switch chip. A spring keeps the heat-conducting sheet firmly attached to the switch chip. A slider can move on a slide rail, allowing the heat-conducting sheet to be adjusted according to the chip positions on different switch motherboards, ensuring maximum heat dissipation efficiency and preventing performance and stability degradation during switch use. However, traditional switches may be accidentally bumped or vibrated during use. These vibrations may be directly transmitted to the inside of the switch, affecting the stability of its electronic components, causing components to loosen, have poor connections or be damaged. In severe cases, it may even cause the switch to malfunction. Furthermore, it is necessary to address the issue of excessive water vapor entering the switch and causing damage in high-temperature and humid working environments.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing switch housing. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-layer protective switch housing for high humidity environments, in order to solve the problem mentioned in the background art that traditional switches may be accidentally bumped and vibrated during use. These vibrations may be directly transmitted to the inside of the switch, thereby affecting the stability of its electronic components, causing components to loosen, have poor connections or be damaged, and in severe cases, even causing the switch to malfunction. It also solves the problem of the switch being damaged due to excessive water vapor entering the inside of the switch in high temperature and humid working environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer protective switch housing for high humidity environments, comprising a first housing and a second housing located inside the first housing, a connecting block fixedly connected to the bottom of the second housing, the connecting block being fixedly connected to the first housing and the second housing, a cavity for placing electronic components of the switch being provided inside the second housing, a rectangular groove being provided inside the first housing, a rectangular plate being engaged with the inner wall of the rectangular groove, the rectangular plate being symmetrically arranged about the axis of the second housing; a shock-absorbing mechanism for reducing vibrations generated by the switch during use is provided between the rectangular plate and the second housing.

[0007] Preferably, the shock absorption mechanism includes a groove formed on the surface of the second housing, a rectangular block slidably connected inside the groove, a connecting plate rotatably connected to the surface of the rectangular block, and a force-bearing block rotatably connected to the end of the connecting plate away from the rectangular block, the force-bearing block pressing against the surface of the rectangular plate.

[0008] Preferably, a telescopic rod is fixedly connected to the side of the force-bearing block, and a first spring is sleeved on the surface of the telescopic rod. The first spring is elastically connected between the force-bearing block and the second housing. The combination of the telescopic rod and the first spring forms a shock-absorbing and damping effect, preventing reverse vibration during the shock absorption process.

[0009] Preferably, the rectangular groove is provided with an assembly mechanism that facilitates the disassembly and installation of the rectangular plate.

[0010] Preferably, the assembly mechanism includes an annular groove formed inside the rectangular groove, and a second spring is disposed inside the annular groove; one end of the second spring is fixedly connected to the inner wall of the groove, and the other end is fixedly connected to a baffle; multiple second springs are symmetrically arranged in the annular groove about the axis of the rectangular plate.

[0011] Preferably, a compression ball is fixedly connected to the side of the baffle, and the compression ball is pressed and adhered to the surface of the rectangular plate.

[0012] Preferably, the rectangular plate has a water-absorbing pad nested inside, which allows the switch to absorb water in a humid environment to maintain the stable operation of the internal components of the second housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the switch housing device reduces the vibration caused by collision during the use of the switch, solves the problem of loose components, poor connection or damage caused by vibration, improves the service life of the switch, maintains the stable operation of the switch, and solves the problem of damage to the switch caused by excessive water vapor entering the switch in the high temperature and humid working environment, ensuring the reliability of the equipment in harsh environments and reducing the failure rate.

[0014] Furthermore, a shock-absorbing mechanism is provided between the rectangular plate and the second housing to reduce the vibration generated by the switch during use. Through the cooperation of components such as the first spring, the force block, and the connecting plate, the force block drives the telescopic rod and the first spring to retract when it is under pressure. Then, the connecting plate rotates and drives the rectangular block to slide inside the groove, avoiding the direct transmission of these vibrations to the components located inside the second housing, thereby improving the service life of the switch and maintaining the stable operation of the switch.

[0015] Furthermore, in high-temperature and humid environments, water vapor can easily enter the switch, damaging its normal operation. Therefore, it is necessary to ensure that the internal components of the switch operate under dry conditions. The groove is equipped with an assembly mechanism that facilitates the disassembly and installation of the rectangular plate. Through the cooperation of components such as the second spring, baffle, and extrusion ball, the rectangular plate drives the water-absorbing pad to slide on the inner wall of the groove. This solves the problem of excessive water vapor entering the switch and causing damage in high-temperature and humid working environments, ensuring the reliability of the equipment in harsh environments and reducing the failure rate.

[0023] 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.

[0024] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a multi-layer protective switch housing for high humidity environments, comprising a first housing 1 and a second housing 2 located inside the first housing 1. A connecting block 3 is fixedly connected to the bottom of the second housing 2, and the connecting block 3 is fixedly connected to the first housing 1 and the second housing 2. A cavity 4 for placing electronic components of the switch is provided inside the second housing 2. A rectangular groove 5 is provided inside the first housing 1, and a rectangular plate 6 is engaged with the inner wall of the rectangular groove 5. The rectangular plate 6 is symmetrically arranged about the axis of the second housing 2. A mechanism is provided between the rectangular plate 6 and the second housing 2 to reduce vibration generated by the switch during use. The shock absorption mechanism includes a groove 8 formed on the surface of the second housing 2. A rectangular block 10 is slidably connected inside the groove 8. A connecting plate 11 is rotatably connected to the surface of the rectangular block 10. A force-bearing block 12 is rotatably connected to the end of the connecting plate 11 away from the rectangular block 10. The force-bearing block 12 is pressed against the surface of the rectangular plate 6. A telescopic rod 13 is fixedly connected to the side of the force-bearing block 12. A first spring 14 is sleeved on the surface of the telescopic rod 13. The first spring 14 is elastically connected between the force-bearing block 12 and the second housing 2. The combination of the telescopic rod 13 and the first spring 14 constitutes a shock absorption damping effect, avoiding reverse vibration during the shock absorption process.

[0025] When the switch is subjected to a collision during operation, the first housing 1 vibrates, and the rectangular plate 6 moves closer to the center of the second housing 2 due to the vibration. At this time, the force-bearing block 12 is squeezed and begins to move towards the center of the second housing 2. The telescopic rod 13 fixed on the force-bearing block 12 and the second housing 2 and the first spring 14 sleeved on the telescopic rod 13 begin to contract under force. At this time, the connecting plate 11 connected to the force-bearing block 12 rotates and drives the rectangular block to slide away from the center of the second housing 2 inside the groove 8 of 10. Since the combination of the telescopic rod 13 and the first spring 14 forms a shock-absorbing and damping effect, reverse vibration is avoided during the shock absorption process, and these vibrations are prevented from being directly transmitted to the components located inside the second housing 2, thereby improving the service life of the switch and maintaining the stable operation of the switch.

[0026] Example 2: Based on Example 1, an assembly mechanism is also disclosed, the specific structure of which is as follows: An assembly mechanism is provided inside the rectangular groove 5 to facilitate the disassembly and installation of the rectangular plate 6. The assembly mechanism includes an annular groove 15 opened inside the rectangular groove 5, and a second spring 16 is provided inside the annular groove 15. One end of the second spring 16 is fixedly connected to the inner wall of the groove 8, and the other end is fixedly connected to a baffle 17. Multiple second springs 16 are symmetrically arranged in the annular groove 15 about the axis of the rectangular plate 6. A compression ball 9 is fixedly connected to the side of the baffle 17. The compression ball 9 is pressed and adhered to the surface of the rectangular plate 6. A water-absorbing pad 7 is nested inside the rectangular plate 6 to absorb water in a humid environment to maintain the stable operation of the internal components of the second housing 2.

[0027] In a high-temperature and humid working environment, external water vapor enters the interior of the switch, causing the absorbent pad 7 nested on the rectangular plate 6 to absorb water. However, if the switch is in a high-temperature and humid environment for a long time, the absorbent pad 7 needs to be replaced. When a new absorbent pad 7 is nested on the rectangular plate 6, the rectangular plate 6 is slid into the groove 8. The rectangular plate 6 squeezes the baffle 17 and the squeeze ball 9, causing the second spring 16, which is tightly attached to the baffle 17, to be compressed and contracted inside the annular groove 15. This makes the rectangular plate 6 firmly installed on the inner wall of the first housing 1, reducing the difficulty of disassembling the rectangular plate 6 to replace the internal absorbent pad 7, ensuring the reliability of the equipment in harsh environments, and reducing the failure rate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
