Description

Technical Field

[0001] The utility model relates to the technical field of communication, in particular to a track installation structure for a communication module. Background Art

[0002] DIN rail is the German industrial standard. DIN is a relatively convenient installation method for industrial electrical components. The advantage is that it does not require screws to fix and is relatively easy to repair and disassemble. When electrical components are installed on DIN rails, DIN rail clips are required to fix the electrical components on the DIN rails.

[0003] In the prior art, most of the plastic clips for installing electrical component tracks do not have resilience. During installation, the clip needs to be pulled outward with a screwdriver until the clip is stuck in a fixed position away from the track. After the electrical component is stuck in the track, the clip needs to be pushed toward the track with a screwdriver until the clip is stuck in a position that can fix the DIN track. Since the clip has no resilience, tools are needed to pull the clip outward and return it to a fixed position. Since there is no resilience, the electrical component is easily loosened when it is fixed on the DIN track. Therefore, the market has also introduced some high-strength steel springs and steel clips for use in combination to make the clip have resilience. However, the steel spring is easy to rust, resulting in a decrease in elasticity, and the installation of a small spring in the clip structure undoubtedly increases the difficulty of assembly and reduces production efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1-6As shown, the embodiment of the present application proposes a rail installation structure for a communication module, including: a shell 100 and a DIN rail buckle 200, the shell 100 is provided with a shell body 1 and a first limiting column 2, a second limiting column 3, a limiting clamping column 4, a first limiting clamping wall 5 and a second limiting clamping wall 6 arranged on the shell body 1, the shell body 1 is also provided with a first clamping slot 7, a second clamping slot 8 and a DIN rail clamping slot 9, the first clamping slot 7 and the second clamping slot 8 are respectively located on the left and right sides of the limiting clamping column 4, and the DIN rail clamping slot 9 is located on the upper side of the limiting clamping column 4; the DIN rail buckle 200 is provided with a clamping body 10 and a first elastic rod 11, a second elastic rod 12, a limiting rod 13, a third limiting wall 14, a fourth limiting wall 15, a first slide 16, a second slide 17 and a first foot 18 arranged on the buckle body 10, the buckle body 10 is provided with a through opening 19, the first elastic rod 11, the second elastic rod 12 and the limiting rod 13 are all arranged in the through opening 19, the first slide 16 and the second slide 17 are respectively located on the left and right sides of the limiting rod 13, and the first foot 18 is located at the top of the buckle body 10; wherein the DIN rail buckle 200 is installed on the housing 100, the The first elastic rod 11 and the second elastic rod 12 are arranged in the through hole 19 in a V shape, the first elastic rod 11 is located on the upper side of the first limiting column 2, the second elastic rod 12 is located on the upper side of the second limiting column 3, and the distance between the first limiting column 2 and the second limiting column 3 is smaller than the maximum opening distance of the V shape, so that when the DIN rail buckle 200 moves downward, the first elastic rod 11 and the second elastic rod 12 are elastically deformed and rebound; the limiting clamping column 4 is located at the lower side of the limiting rod 13 and is spaced from the limiting rod 13 to limit the downward movement of the DIN rail buckle 200. The DIN rail buckle 200 slides and separates from the housing 100; the first limit card wall 5 is engaged with the third limit card wall 14, and the second limit card wall 6 is engaged with the fourth limit card wall 15 to limit the DIN rail buckle 200 from sliding upward; the first slide buckle 16 is matched with the first card slot 7, and the second slide buckle 17 is matched with the second card slot 8 to enable the DIN rail buckle 200 to be slidably installed into the housing 100 and to limit the DIN rail buckle 200 from detaching backward from the housing 100; the first clamping foot 18 is located in the DIN rail card slot 9, and is used to clamp the DIN rail.

[0035] Based on the above technical solution, the rail installation structure for the communication module of the present application uses the first elastic rod 11 and the second elastic rod 12 to form a V-shaped structure with good elasticity, and cooperates with the first limiting column 2 and the second limiting column 3. When the DIN rail buckle 200 is subjected to the downward movement force, the V-shaped structure will be squeezed and deformed by the first limiting column 2 and the second limiting column 3, thereby generating a force to make the DIN rail buckle 200 rebound and return to its original position. When the downward movement force disappears, the DIN rail buckle 200 immediately rebounds and returns to its original position, and the limiting column 4 cooperates with the limiting rod 13 to limit the DIN rail buckle 200. The track buckle 200 is separated from the housing 100 downward, and the first limit card wall 5 and the third limit card wall 14, the second limit card wall 6 and the fourth limit card wall 15 cooperate to limit the DIN track buckle 200 from separating upward from the housing 100, and the first slide buckle 16 and the first card slot 7, the second slide buckle 17 and the second card slot 8 cooperate to limit the DIN track buckle 200 from separating backward from the housing 100, so that the first card foot 18 can press the DIN track tightly and fix the communication module tightly on the DIN track, thereby realizing the characteristics of good resilience of the DIN track buckle 200, stable and reliable installation, and convenient and quick disassembly.

[0036] Among them, the first elastic rod 11 and the second elastic rod 12 are preferably curved elastic rods, that is, the first elastic rod 11 and the second elastic rod 12 both have a certain curvature, and the curvature makes the V-shaped opening formed by the first elastic rod 11 and the second elastic rod 12 gradually expand from bottom to top, thereby further increasing the accumulation of resilience when the DIN rail buckle 200 moves downward, so that the DIN rail buckle 200 can rebound better; more preferably, the DIN rail buckle 200 is injection molded with a plastic material with good elasticity, so that the first elastic rod 11, the second elastic rod 12 and the limit rod 13 have good elasticity.

[0037] The first slide buckle 16 and the second slide buckle 17 can slide upward or downward under the guidance of the first card slot 7 and the second card slot 8 respectively, and limit the DIN rail buckle 200 from falling off from the buckle placement structure toward the bottom side direction, that is, limit the DIN rail buckle 200 from separating backward from the shell 100; in the process of sliding the first slide buckle 16 and the second slide buckle 17, when the first limit card wall 5 is engaged with the third limit card wall 14 and the second limit card wall 6 is engaged with the fourth limit card wall 15, the DIN rail buckle 200 can no longer continue to slide upward, that is, limit the DIN rail buckle 200 from separating upward from the shell 100; in the process of sliding the first slide buckle 16 and the second slide buckle 17, when the limit card column 4 is engaged with the limit rod 13, the DIN rail buckle 200 can no longer continue to slide downward, that is, limit the DIN rail buckle 200 from separating downward from the shell 100.

[0038] It should be noted that in order to ensure the flexibility of the installation of the DIN rail buckle 200, when the DIN rail buckle 200 is installed in place on the shell 100, the limit post 4 and the limit rod 13 are not engaged at this time, which leaves a certain rebound space for the installation of the DIN rail buckle 200 and the shell 100. The DIN rail buckle 200 can move downward for a certain distance when subjected to the downward force, but once the force is no longer applied, the DIN rail buckle 200 will rebound due to the elastic force of the first elastic rod 11 and the second elastic rod 12, and if the force is too large, the limit rod 13 will abut against the limit post 4, thereby preventing the DIN rail buckle 200 from detaching under the dual effects of the clamping force and the elastic force.

[0039] In some embodiments of the present application, Figure 1-4 As shown, the housing body 1 includes a bottom housing 101 and a main housing 102, the bottom housing 101 has a first accommodation space 103, the main housing 102 has a second accommodation space 104, the first accommodation space 103 and the second accommodation space 104 are arranged opposite to each other, the first limiting column 2, the second limiting column 3, the limiting clamping column 4, the first limiting clamping wall 5, the second limiting clamping wall 6, the first clamping slot 7, the second clamping slot 8 and the DIN rail clamping slot 9 are all located on the side of the bottom housing 101 away from the first accommodation space 103. The housing body 1 is formed by buckling two parts of the housing, the bottom housing 101 and the main housing 102 respectively open the first accommodation space 103 and the second accommodation space 104, the two are buckled relative to each other to form a space for accommodating structures such as circuit boards, and the bottom housing 101 and the main housing 102 are assembled into a communication module housing 100.

[0040] In some embodiments of the present application, Figure 1 , 2 As shown, the housing 100 is further provided with a second clamping pin 20, the second clamping pin 20 is located at the upper side of the housing 100, the DIN rail clamping slot 9 is located in the middle of the housing 100, and the first clamping pin 18 is located at the lower side of the housing 100. The second clamping pin 20 is arranged in cooperation with the first clamping pin 18, and clamps the DIN rail from both the upper and lower sides, so that the communication module is tightly clamped on the DIN rail.

[0041] Specifically, Figure 1 , 4 As shown in FIG. 6, the first clamping foot 18 and the second clamping foot 20 are both provided with a sliding angle 21, and the surface opposite to the sliding angle 21 is provided with a step-shaped drop. The sliding angle 21 plays a guiding role, which can make the DIN rail enter the DIN rail slot 9 more easily, and the step-shaped drop allows the first clamping foot 18 and the second clamping foot 20 to better press the DIN rail to prevent it from loosening or shaking.

[0042] In some embodiments of the present application, Figure 1-4 As shown, the first limiting column 2 is located between the limiting column 4 and the first slot 7, the second limiting column 3 is located between the limiting column 4 and the second slot 8, and the limiting column 4 is located at the lower side of the first limiting column 2 and the second limiting column 3. The limiting column 4 is located in the middle position, the first limiting column 2 and the second limiting column 3 are respectively arranged on both sides of the limiting column 4, the first slot 7 and the second slot 8 are also arranged on both sides of the limiting column 4 and are located at a more outer position relative to the first limiting column 2 and the second limiting column 3, which ensures that the various structures do not interfere with each other after installation, and the limiting column 4 is arranged at the lower side of the first limiting column 2, which can ensure that the DIN rail buckle 200 has a certain rebound distance, avoiding the problem that the upward and downward positions are both stuck, resulting in the DIN rail buckle 200 being unable to move within a limited distance.

[0043] In some embodiments of the present application, Figure 2 , 4 As shown, the lower side of the limit post 4 is inclined, and the lower side of the limit post 4 is connected to the housing 100 at an obtuse angle. The oblique angle serves as a guide, facilitating the smooth installation of the DIN rail buckle 200 into the corresponding installation position of the housing 100.

[0044] Specifically, Figure 1 , 5 As shown in Figures 6, the limiting rod 13 is connected to the middle position of the upper side of the buckle body 10, the limiting rod 13 is tilted, the upper side of the limiting rod 13 is thin and the lower side is thick, and the lower end of the limiting rod 13 is suspended. The connection position of the limit rod 13 corresponds to the limit post 4 on the shell 100, and the limit rod 13 is thin at the top and thick at the bottom with the lower end suspended. This allows the DIN rail buckle 200 to be installed. As the slider slides upward in the slot, the limit rod 13 is lifted toward the rear side of the shell 100 under the abutment of the limit post 4 until the lower end of the limit rod 13 exceeds the limit post 4. The limit rod 13 returns to the initial state under the action of elasticity. At this time, the bottom end of the limit rod 13 and the top end of the limit post 4 form a clamping position, thereby limiting the DIN rail buckle 200 from detaching from the shell 100 from the bottom; preferably, the front side surface of the limit rod 13 is almost flush with the front side surface of the DIN rail buckle 200, and the rear side surface of the limit rod 13 is recessed forward compared with the rear side surface of the DIN rail buckle 200.

[0045] In some embodiments of the present application, Figure 1 , 2As shown in Figures 5 and 6, the top of the first elastic rod 11 is provided with a first cylinder 22, and the top of the second elastic rod 12 is provided with a second cylinder 23. The cylindrical structure at the top makes the top of the elastic rod have a strong anti-deformation ability, and the section from the cylinder to the root of the elastic rod is thin and elastic, and is easy to deform under force, so that the strength and deformation ability of the first elastic rod 11 and the second elastic rod 12 are taken into account.

[0046] In some embodiments of the present application, Figure 2 , 5 As shown in FIG. 6 , a first U-shaped groove 24 is formed at one side of the bottom end of the first elastic rod 11, and a second U-shaped groove 25 is formed at one side of the bottom end of the second elastic rod 12. The U-shaped grooves leave the roots of the first elastic rod 11 and the second elastic rod 12 hollow, thereby increasing the elasticity of the first elastic rod 11 and the second elastic rod 12.

[0047] In some embodiments of the present application, Figure 1 , 2 As shown in FIGS. 5 and 6, the buckle body 10 includes a mounting portion 1001 and a head portion 1002. The head portion 1002 is connected to the lower side of the mounting portion 1001. The through opening 19 is provided in the mounting portion 1001. The head portion 1002 is provided with a tool insertion slot 1003. The mounting portion 1001 is installed on the housing 100, and the head portion 1002 can assist in disassembly. When the communication module needs to be disassembled from the DIN rail, a flat-blade screwdriver can be inserted into the tool insertion slot 1003 of the head portion 1002, and then the flat-blade screwdriver can be used to lift and pull the DIN rail buckle 200 until the communication module is detached from the DIN rail.

[0048] The following is an explanation of the assembly and disassembly process of this application:

[0049] During assembly, the first slide buckle 16 and the second slide buckle 17 are aligned with the first card slot 7 and the second card slot 8 respectively and pushed forward to a certain depth, and then the first elastic rod 11 and the second elastic rod 12 are squeezed with fingers to make the opening of the V-shaped structure formed by the first elastic rod 11 and the second elastic rod 12 change from large to small, so that the first elastic rod 11 and the second elastic rod 12 can pass through the gap between the first limit column 2 and the limit card column 4 and the gap between the second limit column 3 and the limit card column 4 respectively, and continue to push the first slide buckle 16 and The second slide buckle 17 enters the first slot 7 and the second slot 8 until a click sound is heard. The click sound is caused by the front side of the limit rod 13 sliding over the oblique angle of the limit column 4. When the top of the limit rod 13 passes over the limit column 4, the top of the limit rod 13 falls from a high place to a low place and hits the surface of the shell 100, making a sound. At this time, the limit column 4 blocks the limit rod 13 from sliding downward, and the DIN rail buckle 200 will not be able to fall off from the shell 100, that is, the DIN rail buckle 200 is successfully installed in the shell 100.

[0050] Furthermore, the limit rod 13 in this embodiment has an inclination, and the root of the limit rod 13 connected to the DIN rail buckle 200 is relatively thin, and the root of the limit rod 13 is extended to the lower end of the limit rod 13 and gradually becomes thicker, the lower end is the thickest, and the lower end is suspended. The DIN rail buckle 200 adopts a plastic material with good elasticity, thereby making the limit rod 13 have good elasticity, and the limit column 4 has an oblique angle, so that the limit rod 13 can smoothly pass over the limit column 4 during assembly. When the limit rod 13 passes over the limit column 4, the limit column 4 prevents the limit rod 13 from sliding down, making the assembly process very convenient.

[0051] Furthermore, when the DIN rail buckle 200 is to be separated from the housing 100 , the limiting rod 13 is first tilted slightly higher than the limiting column 4 , and the DIN rail buckle 200 is driven downward by force until the DIN rail buckle 200 is separated from the housing 100 .

[0052] Furthermore, in this embodiment, there is only one limiting rod 13, so only the single limiting rod 13 needs to be pulled up to remove the obstacle of the DIN rail buckle 200 being separated from the housing 100, making the disassembly process very convenient.

[0053] Furthermore, when the communication module is installed on the DIN rail, one side of the DIN rail is first inserted into the second clamping pin 20, and then the lower side of the communication module, that is, the side at the bottom where the DIN rail clamping pin 200 is provided, is pressed down with force, and the other side of the DIN rail and the bottom side of the first clamping pin 18 are in contact and squeezed against each other, and the DIN rail clamping pin generates a downward movement force due to the squeezing of the DIN rail. Since the first elastic rod 11 and the second elastic rod 12 are provided on the lower side wall of the square opening 19, the first elastic rod 11 and the second elastic rod 12 are arranged in a V-shaped structure, and the first limiting column 2 and the second limiting column 3 control the opening of the first elastic rod 11 and the second elastic rod 12 to form the V-shaped structure. The size of the opening, when the DIN rail buckle 200 moves downward, the first elastic rod 11 and the second elastic rod 12 will be squeezed by the first limiting column 2 and the second limiting column 3, so that the V-shaped structure is deformed, so that the V-shaped opening is reduced from large to small, thereby condensing the force that makes the DIN rail buckle 200 rebound and return to its original position. When the DIN rail slides through the rail sliding angle 21 and enters the front side of the first clamping foot 18, the downward movement force disappears, and the condensed DIN rail buckle 200 rebounds quickly to its original position. The front side of the first clamping foot 18 will press the DIN rail tightly, so that the communication module does not need to use tools when installing on the DIN rail, and the installation is very convenient.

[0054] Furthermore, in the present embodiment, the top ends of the first elastic rod 11 and the second elastic rod 12 are provided with top cylinders, and the top cylinders make the top end of the curved elastic rod have strong anti-deformation ability, and the section from the top cylinder to the root of the curved elastic rod is thin and elastic, and is easily deformed under force. The DIN rail buckle 200 adopts a plastic material with good elasticity, so the first elastic rod 11 and the second elastic rod 12 have good elasticity and are easy to deform, and the top cylinder has strong anti-deformation ability. When the DIN rail buckle moves downward until the first limiting column 2 and the second limiting column 3 are respectively in close contact with the top cylinder, the DIN rail buckle 200 will gather greater resilience.

[0055] Furthermore, when the communication module is to be removed from the DIN rail, a flat-blade screwdriver may be inserted into the tool insertion slot 1003 of the head 1002, and then the flat-blade screwdriver may be used to lift and pull the DIN rail buckle 200 until the communication module is detached from the DIN rail.

[0056] In summary, the rail installation structure for the communication module of the present application uses the first elastic rod 11 and the second elastic rod 12 to form a V-shaped structure with good elasticity, and cooperates with the first limiting column 2 and the second limiting column 3. When the DIN rail buckle 200 is subjected to a downward movement force, the V-shaped structure will be squeezed and deformed by the first limiting column 2 and the second limiting column 3, thereby generating a force to make the DIN rail buckle 200 rebound and return to its original position. When the downward movement force disappears, the DIN rail buckle 200 immediately rebounds and returns to its original position, and the limiting column 4 cooperates with the limiting rod 13 to limit the DIN rail buckle The buckle 200 is separated from the housing 100 downward, and the first limit card wall 5 and the third limit card wall 14, the second limit card wall 6 and the fourth limit card wall 15 cooperate to limit the DIN rail buckle 200 from separating upward from the housing 100, and the first slide buckle 16 and the first card slot 7, the second slide buckle 17 and the second card slot 8 cooperate to limit the DIN rail buckle 200 from separating backward from the housing 100, so that the first card foot 18 can press the DIN rail tightly and fix the communication module tightly on the DIN rail, thereby achieving the characteristics of good resilience of the DIN rail buckle 200, stable and reliable installation, and convenient and quick disassembly.

[0057] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
