Description

Technical Field

[0001] This utility model relates to the field of signal isolation equipment technology, and more specifically, to an isolator. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] Isolators, as instruments used for signal isolation, conversion, and transmission, are widely used in industrial control systems. In practical applications, to facilitate high-density, modular installation in distribution cabinets or control cabinets, most isolators are secured to DIN-standard 35mm DIN rails via a specific snap-fit ​​structure on the back of their housing.

[0004] Currently, most mainstream isolators on the market use a snap-fit ​​structure, where the relative positions of the two snaps used to engage the upper and lower edges of the guide rail are usually fixed. While this fixed-pitch design can match standard DIN rails, it also leads to obvious limitations: when the user's guide rail is non-standard or has manufacturing tolerances, the fixed-pitch isolator is difficult to install, or even if forced to install, the housing will be subjected to continuous stress, posing a risk of damage. Therefore, the snap-fit ​​structure used in existing isolators suffers from poor versatility and difficulty in adapting to non-standard or non-ideal guide rails. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide an isolator that at least overcomes the technical problems of poor versatility and difficulty in adapting to non-standard or non-ideal guide rails caused by the snap-fit ​​structure used in existing isolators.

[0006] The objective of this utility model is achieved through the following technical solution: This utility model provides an isolator, including a housing, on which a snap-fit ​​structure for mounting onto a guide rail is provided. The snap-fit ​​structure includes a first snap-fit ​​and a second snap-fit ​​disposed opposite to each other along a first direction. The first snap-fit ​​is fixedly disposed on the housing and adapted to engage with the upper edge of the guide rail. The second snap-fit ​​is adapted to engage with the lower edge of the guide rail. The housing is provided with a movable cavity, and the outer wall of the housing is provided with a clearance opening that communicates with the movable cavity and extends along the first direction; The movable cavity is provided with a screw that extends along the first direction and is rotatable; a movable part is threadedly connected to the screw, and one end of the movable part passes through the clearance opening and is connected to the second buckle.

[0007] Optionally, the bottom of the housing is provided with a mounting port communicating with the movable cavity; The screw is rotatably mounted on a mounting block; the mounting block is detachably mounted at the mounting opening.

[0008] Optionally, the mounting block is provided with a threaded hole; the outer wall of the housing is provided with a connection hole that matches the threaded hole.

[0009] Optionally, the connecting hole is a countersunk hole.

[0010] Optionally, one end of the screw extends outside the housing and is provided with a knob.

[0011] Optionally, the knob is located at the bottom of the housing.

[0012] Optionally, the outer wall of the housing is provided with an indicator mark for indicating the position of the second latch.

[0013] Optionally, the indicator is a scale line extending along the first direction; the second buckle is provided with an indicator portion pointing to the scale line.

[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects: The isolator provided by this utility model, by setting the second buckle to be movable and adding a driving mechanism composed of a screw, a moving part and other components to drive the second buckle to move closer to or away from the first buckle, realizes the adjustment of the distance between the first buckle and the second buckle. This allows the isolator to be installed on guide rails of various widths by means of the buckle structure, effectively overcoming the technical problems of poor versatility and difficulty in adapting to non-standard or non-ideal guide rails that exist in the fixed buckle structure of existing isolators.

[0019] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0020] Please refer to Figures 1 to 7 As shown, an embodiment of the present invention provides an isolator, and more particularly an isolator suitable for mounting on a guide rail 100.

[0021] According to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the isolator includes a housing 10. The housing 10 is provided with a locking structure for mounting onto a guide rail 100.

[0022] The engaging structure includes a first latch 20 and a second latch 30 disposed opposite to each other along a first direction. The first latch 20 is fixedly disposed on the housing 10 and adapted to engage with the upper edge 101 of the guide rail 100. The second latch 30 is adapted to engage with the lower edge 102 of the guide rail 100. In this embodiment of the invention, the first direction refers to the width direction of the guide rail 100, that is, the direction of the line connecting the upper edge 101 and the lower edge 102 of the guide rail 100. Preferably, both the first latch 20 and the second latch 30 are located on the rear side of the housing 10.

[0023] Reference Figure 3 As shown, the housing 10 also has a movable cavity 11, which can extend along a first direction. The outer wall of the housing 10 has a clearance opening 12 that communicates with the movable cavity 11 and extends along the first direction. The movable cavity 11 has a screw 40 that extends along the first direction and is rotatable. A moving part 50 is threadedly connected to the screw 40, and one end of the moving part 50 passes through the clearance opening 12 and is connected to the second latch 30.

[0024] Based on the above setup, during actual installation of the isolator, first engage the first latch 20 with the upper edge 101 of the guide rail 100. Then, rotate the screw 40. Based on the principle of threaded transmission, the moving part 50 will move along the axial direction (i.e., the first direction) of the screw 40, thereby driving the second latch 30 closer to the first latch 20 until the second latch 30 engages with the lower edge 102 of the guide rail 100. Conversely, when it is necessary to remove the isolator from the guide rail 100, first rotate the screw 40 in the opposite direction, so that the moving part 50 drives the second latch 30 away from the first latch 20 and disengages it from the guide rail 100. Then, disengage the first latch 20 from the guide rail 100.

[0025] The isolator provided in this embodiment of the utility model, by making the second buckle 30 movable and adding a driving mechanism composed of a screw 40, a moving part 50 and other components to drive the second buckle 30 to move closer to or away from the first buckle 20, realizes the adjustment of the distance between the first buckle 20 and the second buckle 30. This allows the isolator to be installed on guide rails 100 of various widths by means of the buckle structure, effectively overcoming the technical problems of poor versatility and difficulty in adapting to non-standard or non-ideal guide rails 100 that exist in the fixed buckle structure of existing isolators.

[0026] Furthermore, the drive mechanism, composed of components such as the screw 40 and the moving part 50, drives the movement of the second latch 30, enabling stepless adjustment of its position. This results in smoother and more precise movement of the second latch 30 and facilitates fine-tuning of its position. Secondly, the self-locking property of the screw 40 transmission allows for locking the second latch 30 at a predetermined position, reducing the risk of the isolator loosening under vibration. Moreover, integrating the screw 40, the moving part 50, and other components within the movable cavity 11 of the housing 10 creates a rational structural layout, allowing the isolator to retain its original compact design.

[0027] In some possible embodiments, refer to Figures 4 to 6 As shown, the bottom of the housing 10 has a mounting port 13 that communicates with the movable cavity 11. The screw 40 is rotatably mounted on a mounting block 60 via a bearing. Furthermore, the mounting block 60 is detachably mounted at the mounting port 13.

[0028] This structural design eliminates the direct connection between the screw 40 and the housing 10, thus facilitating the assembly and disassembly of the screw 40. Specifically, when disassembling the screw 40, first disconnect the mounting block 60 from the housing 10, and then disconnect the threaded connection between the screw 40 and the moving part 50.

[0029] In a preferred embodiment, the mounting block 60 can be connected to the housing 10 by fasteners such as screws 70. Specifically, referring to... Figures 4 to 6 As shown, the mounting block 60 has a threaded hole 61. The outer wall of the housing 10 has a connecting hole 14 that matches the threaded hole 61. During installation, the mounting block 60 is first inserted into the mounting opening 13 so that the threaded hole 61 is aligned with the connecting hole 14. Then, the screw 70 is passed through the connecting hole 14 and threadedly connected to the threaded hole 61, thus fixing the mounting block 60.

[0030] Furthermore, the connecting hole 14 is opened on the rear outer wall of the housing 10, and can be a countersunk hole to prevent the screw 70 from protruding from the outer wall of the housing 10.

[0031] In some possible embodiments, refer to Figure 5 or Figure 6 As shown, one end (specifically the bottom end) of the screw 40 extends to the outside of the housing 10 and is provided with a knob 80. Preferably, the knob 80 can be located at the bottom of the housing 10 to further optimize the structural design of the isolator.

[0032] The knob 80 allows for convenient operation of the screw 40. Preferably, the outer wall of the knob 80 is provided with an anti-slip structure (such as anti-slip texture or anti-slip groove) to prevent the operator from slipping when turning the knob 80.

[0033] In some possible embodiments, refer to Figure 1 As shown, the outer wall of the housing 10 can be provided with an indicator mark 90 for indicating the position of the second latch 30. The indicator mark 90 can help determine the distance between the second latch 30 and the first latch 20, thereby improving the efficiency of installing the isolator. Specifically, during installation, the operator can first adjust the second latch 30 to a suitable position according to the width of the guide rail 100 and the indication of the indicator mark 90, so that the distance between the second latch 30 and the first latch 20 is slightly greater than the width of the guide rail 100; after the first latch 20 is engaged with the upper edge 101 of the guide rail 100, the operator only needs to fine-tune the position of the second latch 30 to make the second latch 30 engage with the lower edge 102 of the guide rail 100.

[0034] In a preferred embodiment of this invention, referring to Figure 7 As shown, the indicator mark 90 is a scale line extending along the first direction. The second latch 30 is provided with an indicator part 91 pointing to the scale line, which helps the operator to clearly know the distance between the second latch 30 and the first latch 20.

[0035] In some possible embodiments, the first buckle 20 and the housing 10 are an integral structure to ensure the integrity of the housing 10 structure and facilitate the manufacturing and processing of the housing 10 and the first buckle 20.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
