Description

Technical Field

[0001] This utility model relates to the field of signal isolator technology, and more specifically, it relates to a multi-layer isolation signal isolator protective housing. Background Technology

[0002] Signal isolators are critical devices used in industrial automation systems. Through photoelectric, magnetoelectric, or capacitive isolation technologies, they block ground loops, suppress electromagnetic interference, and ensure the stability and security of signal transmission. They support standard signals such as 4-20mA and 0-10V, and feature high accuracy (±0.1%), high isolation voltage (1kV~3kV), and strong anti-interference capabilities, making them suitable for harsh environments such as power, chemical, and medical industries. Their modular design facilitates installation and maintenance, and some models also include surge protection and fault diagnosis functions, ensuring long-term reliable system operation.

[0003] Signal isolators are often used in close-packed arrays to create multiple layers of isolation. However, this close-packed arrangement can lead to poor heat dissipation at the points where the isolators are in contact with each other, especially in the middle section. This can easily cause heat to accumulate and not dissipate quickly, affecting the performance and lifespan of the signal isolators. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the problems existing in the prior art, this utility model provides a multi-layer isolated signal isolator protective housing to solve the technical problem mentioned in the background art of poor heat dissipation when multi-layer isolated signal isolators are used in densely arranged configurations.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-layer isolated signal isolator protective housing includes a heat dissipation base, on which multiple sets of heat-conducting plates are slidably disposed. A movable adjustment structure is provided between the heat-conducting plates and the heat dissipation base. A limit block is rotatably disposed on the inner side of the heat-conducting plates, and multiple heat dissipation fins are uniformly disposed on the outer side of the heat dissipation base.

[0009] The present invention is further configured such that the heat dissipation base is provided with an installation groove, and the heat conduction plate is provided with an installation slider. The installation slider is slidably located in the installation groove. Through the cooperation of the installation groove and the installation slider, the heat conduction plate can be slidably and adjustablely installed on the heat dissipation base, thereby facilitating the use of the heat conduction base plate with the signal isolator. At the same time, the heat conduction plate can be used with different models of signal isolators.

[0010] The present invention is further configured such that the movable adjustment structure includes a locking groove, the locking groove extending outward from the mounting slide groove, and a locking pin threaded on the mounting slider. The locking pin extends to the outside of the locking groove and is provided with a locking knob. Tightening the locking knob controls the rotation of the locking pin, thereby pressing and fixing the locking knob onto the side wall of the heat dissipation base, thus achieving the locking and fixing of the locking pin in the locking groove, and further achieving the locking and fixing of the mounting slider in the mounting slide groove, thereby achieving the installation and fixing of the heat conduction plate on the heat dissipation base.

[0011] The present invention is further configured such that the limiting block is provided with an installation shaft, the heat-conducting plate is provided with an installation groove, and a bearing is provided between the installation shaft and the installation groove. The limiting block can be rotatably installed on the heat-conducting plate through the cooperation of the installation shaft and the installation groove. The bearing can improve the installation stability of the installation shaft in the installation groove.

[0012] The present invention is further provided that a damping pad is provided in the mounting groove to cooperate with the mounting shaft. The damping pad can increase the rotational friction resistance between the mounting shaft and the mounting groove, so that after the limiting block is adjusted to a suitable position, the limiting block can be kept stable and fixed, and the limiting block can be prevented from rotating randomly under its own weight.

[0013] The present invention is further configured such that the mounting slide extends toward the heat dissipation fins and has an adjustment groove, the mounting shaft extends to the surface of the mounting slider and has an adjustment groove, the adjustment groove is connected to the adjustment slot, so as to facilitate the rotation adjustment of the limiting block from the outside and improve the rotation convenience of the limiting block.

[0014] The present invention is further configured such that an adjustment operation area is provided in the middle of the heat dissipation fin. When the limiting block is rotated and adjusted, adjustment tools such as screwdrivers can be passed through the adjustment operation area and the adjustment groove in sequence and engaged with the adjustment groove, thereby facilitating the control of the rotation of the mounting shaft. The rotation of the mounting shaft can realize the rotation of the limiting block, thereby realizing the limiting connection between the heat conduction plate and each group of signal isolators, and improving the installation stability of the heat conduction plate between two adjacent groups of signal isolators.

[0015] The present invention is further configured such that the mounting slider has a threaded groove, and the locking pin is threadedly engaged with the threaded groove. The locking pin passes through the locking groove and is threadedly connected with the threaded groove. Thus, when the heat-conducting plate is in the appropriate position, tightening the locking knob will lock the mounting slider in the mounting groove under the threaded engagement between the locking pin and the threaded groove, thereby achieving the locking and fixing of the heat-conducting plate mounting position.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a multi-layer isolated signal isolator protective housing, which has the following beneficial effects:

[0018] 1. This utility model features a heat dissipation base, a heat-conducting plate, and heat dissipation fins that work together. The heat-conducting plate is positioned between two adjacent signal isolators during use. This allows the heat accumulated due to the dense distribution of the signal isolators to be quickly transferred to the heat dissipation base via the heat-conducting plate, and then dissipated through the heat dissipation fins on the base. This enhances the heat dissipation and protection effect of the multi-layer isolated signal isolator during use, improving its performance and lifespan. The heat-conducting plate, heat dissipation base, and heat dissipation fins are all made of materials with good thermal conductivity and heat dissipation properties, such as aluminum-based, copper, aluminum alloy with anodized surface, alumina ceramic, or thermally conductive silicone, which can be selected according to insulation requirements.

[0019] 2. In this utility model, the heat-conducting plate is slidably and adjustablely mounted on the heat dissipation base through the cooperation of the mounting slider and the mounting groove, so that the mounting slider and the inner wall of the mounting groove slide against each other, thereby ensuring heat dissipation and allowing for flexible adjustment of the position of the heat-conducting plate. This improves the convenience of installing the signal isolator and also facilitates the use of different models of signal isolators.

[0020] 3. This utility model provides a limiting block on the inner side of the heat-conducting plate. After the signal isolator and the heat-conducting plate are installed, screwdrivers and other adjustment tools can be passed through the adjustment operation area and adjustment groove in sequence and engaged with the adjustment groove, thereby facilitating the control of the rotation of the mounting shaft. The rotation of the mounting shaft can realize the rotation of the limiting block, thereby realizing the limiting connection between the heat-conducting plate and each group of signal isolators, improving the installation stability of the heat-conducting plate between two adjacent groups of signal isolators, preventing the heat-conducting plate from arbitrarily detaching from the signal isolator, and improving the overall stability of the protective shell.

[0033] Please see Figures 1-5 As one implementation of the mounting groove 11: a damping pad 13 is provided in the mounting groove 11 to cooperate with the mounting shaft 10. The damping pad 13 can increase the rotational friction resistance between the mounting shaft 10 and the mounting groove 11, so that after the limit block 3 is adjusted to a suitable position, the limit block 3 can be kept stable and fixed, and the limit block 3 can be prevented from rotating randomly under its own gravity.

[0034] Please see Figures 1-5 As one embodiment of the mounting slide 5: the mounting slide 5 extends towards the heat dissipation fins 4 and has an adjustment groove 14.

[0037] In summary:

[0038] This utility model features a heat dissipation base 1, a heat-conducting plate 2, and heat dissipation fins 4 that work together. The heat-conducting plate 2 is attached between two adjacent signal isolators during use. This allows the heat accumulated due to the dense distribution of the signal isolators to be quickly transferred to the heat dissipation base 1 via the heat-conducting plate 2, and then dissipated through the heat dissipation fins 4 on the heat dissipation base 1. This enhances the heat dissipation effect of the multi-layer isolated signal isolator during use, improving its performance and lifespan. The heat-conducting plate 2, heat dissipation base 1, and heat dissipation fins 4 are all made of materials with good thermal conductivity and heat dissipation properties, such as aluminum-based, copper, aluminum alloy with anodized surface, alumina ceramic, or thermally conductive silicone, which can be selected according to insulation requirements.

[0039] In this utility model, the heat-conducting plate 2 is slidably and adjustablely mounted on the heat dissipation base 1 by means of the cooperation of the mounting slider 6 and the mounting groove 5, so that the mounting slider 6 and the inner wall of the mounting groove 5 slide and fit together, thereby ensuring heat dissipation and allowing flexible adjustment of the position of the heat-conducting plate 2. This improves the convenience of the signal isolator during installation and also facilitates the use of different models of signal isolators.

[0040] This invention provides a limiting block 3 on the inner side of the heat-conducting plate 2. After the signal isolator and the heat-conducting plate 2 are installed, screwdrivers and other adjustment tools can be passed through the adjustment operation area 16 and the adjustment groove 14 in sequence and engaged with the adjustment groove 15. This facilitates the control of the rotation of the mounting shaft 10. The rotation of the mounting shaft 10 can realize the rotation of the limiting block 3, thereby achieving a limiting connection between the heat-conducting plate 2 and each group of signal isolators. This improves the installation stability of the heat-conducting plate 2 between two adjacent groups of signal isolators, prevents the heat-conducting plate 2 from detaching from the signal isolator at will, and improves the overall stability of the protective shell.
