Technical Field

[0001] This application relates to the field of communication technology, and in particular to a key structure and its communication system. Background Technology

[0002] As the capacity of current communication system equipment continues to expand, more intensive development needs are emerging for the chassis. In this situation, traditional levers occupy a large panel size and a lot of chassis space. The limitations on the number of chassis outlets, the internal space of the chassis, and the number of chassis connectors, which in turn limit the insertion and extraction force, are constantly restricting the development of the chassis's functional characteristics. Moreover, existing levers have force-saving ratios of 1 / 6, 1 / 8, and 1 / 12. As the data capacity of products increases, the number of high-speed connectors required on a single chassis continues to increase, resulting in greater insertion and extraction force per chassis. Current levers cannot meet the usability standards. Utility Model Content

Detailed Implementation

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] See Figures 1 to 9 This application provides a key structure and its communication system, which can solve the problems in related technologies where the key affects the number of outlets on the panel side and cannot meet the requirements of the existing single-panel insertion and extraction force.

[0032] In a first aspect, embodiments of this application provide a key structure, comprising: a support body 3 and a wrench 2. The support body 3 is disposed at the end of a panel structure 6 and located on one side of a panel outlet 60. The wrench 2 is rotatably connected to the support body 3 via a pin 32. The wrench 2 is provided with a force-applying part 20, which extends toward the panel outlet 60. The horizontal plane at the top of the force-applying part 20 is located below the horizontal plane at the bottom of the panel outlet 60. The wrench 2 has a force-applying point and a device mating point 24, which are located on both sides of the pin 32. The ratio of the distance between the device mating point 24 and the pin 32 to the distance between the force-applying point and the pin 32 is greater than or equal to a set threshold.

[0033] In this application, the thickness of the key structure is compressed to the maximum extent. By setting the wrench 2, the top of the force-applying part 20 of the wrench 2 is located below the bottom of the panel outlet 60. Therefore, the force-applying part 20 of the wrench 2 will not occupy the space of the panel outlet 60. Furthermore, the ratio of the distance between the equipment mating point 24 on the wrench 2 and the pin 32 to the distance between the force-applying point and the pin 32 is set to be greater than or equal to a set threshold, so that the key structure can achieve a large force-saving ratio and realize the assisted operation of the large insertion and extraction force plate.

[0034] A key structure is provided on both sides of panel structure 6. The two key structures are symmetrically arranged. The main structure of the key structure is a zinc alloy structural component, and it is designed with a locking and wrench-shaped two-part separation structure.

[0035] Among them, wrench 2 is an assistive structure that uses the lever principle to achieve assisted insertion and extraction. Simultaneously, wrench 2 can rotate relative to support body 3 about pin 32 as its axis. For ease of understanding, in... Figure 1The wrench 2 indicates two mating points 24, and the distance between the mating points 24 and the pin 32 is the same at different locations. The force application points include an insertion force application point 22 and a withdrawal force application point 23, and the distance between the insertion force application point 22 and the pin 32 is the same as the distance between the withdrawal force application point 23 and the pin 32. In this embodiment, a threshold value of 1 / 15 is set, meaning that the ratio of the distance between the mating point 24 and the pin 32 to the distance between the force application point and the pin 32 is greater than or equal to 1 / 15. For example, when the ratio of the distance between the mating point 24 and the pin 32 to the distance between the force application point and the pin 32 is equal to 1 / 15, only 5 kgf of force is needed to apply force to the single-lever key on a 150 kgf high insertion / extraction force machine. Therefore, this setting improves the operability of the lever key structure.

[0036] Therefore, the structural form of this application can be applied to different labor-saving ratio requirements, and can achieve the uniformity of the key style used in different specifications of the machine panel; the horizontal plane at the top of the force-applying part 20 in the key structure is located below the horizontal plane at the bottom of the panel outlet 60, which does not affect the outlet layout of the machine panel, increases the number of physical outlet layouts, and is conducive to improving the cost performance in the market.

[0037] Based on the above embodiments, in this embodiment, the support body 3 includes a support body 30 and a lock body 31, and the support body 30 is used to be mounted on the panel structure 6.

[0038] See Figure 2 As shown, the support body 30 is fixed to the panel structure 6. Specifically, fixing grooves are provided on both sides of the panel structure 6, and the fixing grooves are able to accommodate the support body 30. The support body 30 is placed in the fixing groove and locked to the panel structure 6 with screws. The wrench 2 is provided on the support body 30 and is located on the front of the panel structure 6.

[0039] It should be noted that the pin 32 is mounted on the support body 30, which has a through hole 37. The pin 32 passes through the through hole 37 and engages with the wrench 2 via interference fit, thus serving as the rotating axis for the lever function. A torsion spring 33 is fitted onto the surface of the pin 32. One end of the torsion spring 33 is connected to the wrench 2, and the other end is connected to the support body 3. In other words, the torsion spring 33 uses the support body 30 as its base, and is pre-compressed during the assembly of the wrench 2 and the support body 3. Figure 8 and Figure 9 ,exist Figure 8 In the middle, torsion spring 33 is in its initial state, that is... Figure 9 State A in the middle Figure 9 In state B, the torsion spring 33 is preloaded to the maximum angle, and the preload of the torsion spring 33 supports the wrench 2 to open to the maximum opening angle in the non-locking state.

[0040] To achieve the automatic locking function of the key mechanism, the wrench 2 is designed with an independent locking hook and a spring-loaded structure to achieve elastic locking: the lock body 31 is mounted on the support body 30, and the wrench 2 is provided with a locking hook assembly 1. In the normal state, the wrench 2 is locked to the lock body 31 through the locking hook assembly 1. It should be noted that in this application, in order to avoid the force-applying part 20 of the wrench 2 occupying the space of the panel outlet 60, the size of the locking hook assembly 1 is also compressed to the maximum extent.

[0041] Specifically, the locking hook assembly 1 is movably connected to the wrench 2. In the normal state, the lock body 31 is located on the moving path of the locking hook assembly 1. When the locking hook assembly 1 and the lock body 31 are locked, the locking tongue of the locking hook assembly 1 abuts against the locking tongue of the lock body 31.

[0042] In other words, the locking hook assembly 1 has a first position and a second position, and the locking hook assembly 1 can move between the first position and the second position. In the normal state, when the locking hook assembly 1 moves from the unlocked second position to the first position, the locking hook assembly 1 can be locked with the lock body 31.

[0043] To achieve this functionality, in this embodiment:

[0044] A mounting groove 21 is provided on the wrench 2, and the locking hook assembly 1 is movably connected inside the mounting groove 21. The locking hook assembly 1 includes a fixing base 11, a compression spring 12, and a locking hook body 10. The fixing base 11 is slidably connected inside the mounting groove 21, serving as the assembly base for connecting the locking hook body 10 and the wrench 2. One end of the compression spring 12 is connected to the fixing base 11, and the other end is connected to one side of the inner wall of the mounting groove 21. In the normal state, the compression spring 12 abuts against the fixing base 11, causing the fixing base 11 to abut against the other side of the inner wall of the mounting groove 21. The locking hook body 10 is disposed on the fixing base 11, and the locking tongue of the locking hook body 10 abuts against the locking tongue of the lock body 31. The compression spring 12 provides preload to the locking hook body 10, ensuring that the locking hook body 10 is in a self-locking state in the normal state. During unlocking, the locking hook body 10 is moved horizontally, pressing the compression spring 12, thereby separating the locking hook body 10 from the lock body 31.

[0045] Based on the above embodiments, in this embodiment, the locking hook body 10 is snapped into the inside of the fixing base 11.

[0046] Specifically, the surface of the locking hook body 10 is provided with a groove 100; the fixing base 11 is provided with an elastic arm 110, wherein, see Figure 6As shown, one end of the elastic arm 110 is connected to the fixed base 11, and the other end extends into the fixed base 11, forming a snap-fit ​​structure that can elastically deform, and engaging the elastic arm 110 with the groove 100. In this embodiment, the fixed base 11 utilizes its inherent feature: the elastic arm 110, which engages with the groove 100 on the hook body 10 for fastening. No additional screws or other fasteners are required. The wrench 2 and the hook assembly 1 can be assembled without screws simply by the tight fit between the elastic arm 110 and the groove 100 of the hook body 10. This effectively reduces the safety hazards caused by loose or missing screws and ensures the stability and durability of the entire hook assembly 1.

[0047] Furthermore, to enhance the locking force between the hook body 10 and the fixed base 11, multiple elastic arms 110 are provided inside the fixed base 11. Each elastic arm 110 extends into the fixed base 11 and engages with different positions on the hook body 10, ensuring that each elastic arm 110 maintains sufficient elasticity to meet the locking requirements. Therefore, when the hook body 10 moves, it will cause the fixed base 11 to move along with it.

[0048] Based on the above embodiments, in this embodiment, the toggle switch structure further includes: a cover plate 4 and a micro switch body 5. The two ends of the cover plate 4 are snapped together with the support body 3 via buckles 35, and a micro switch mounting position 34 is formed between the cover plate 4 and the support body 3. The micro switch body 5 is disposed within the micro switch mounting position 34 and abuts against the cover plate 4 and the support body 3, and the micro switch body 5 is used to be mounted on the back of the panel structure 6. Therefore, this application can simultaneously achieve locking, assisted insertion / removal, and micro switch positioning and fixation.

[0049] The cover plate 4 is an auxiliary structure for mounting the micro switch body 5. It is used in conjunction with the micro switch body 5 and is not needed when the micro switch function is not required.

[0050] A microswitch mounting position 34 is provided on the support body 3. In this application, the layout of the I / O outlets on the panel side is not affected, thus accommodating both scenarios with and without microswitches. When a microswitch is required: using the support body 3 as a base, the cover plate 4 and the microswitch body 5 are installed at the microswitch mounting position 34 on the support body 3 for snap-fit ​​fixation. The locking hook assembly 1, the wrench 2, and the support body 3 are then assembled into a single unit to obtain the lever structure of this application. When a microswitch is not required: the locking hook assembly 1, the wrench 2, and the support body 3 are then assembled into a single unit to obtain the lever structure of this application.

[0051] After installation, the micro switch body 5 is located on the back of the panel structure 6, isolating the unlocking structure from the assisting structure. This prevents the lever structure from directly opening and accidentally triggering the micro switch function when the assisting wrench 2 is accidentally activated. A through groove 36 is provided on the support body 30, and a buckle 35 is fixed in the through groove 36. (See attached image) Figure 5As shown, a slot 40 is provided on the cover plate 4, and the buckle 35 is engaged with the slot 40. In order to achieve the stability of the connection between the cover plate 4 and the support body 30, a buckle 35 is also fixed at the relative position of the through slot 36 on the support body 30. The two buckles 35 fix the two sides of the cover plate 4 to fix the micro switch body 5 between the cover plate 4 and the support body 30.

[0052] Secondly, embodiments of this application provide a communication system, which includes a key structure and a panel structure 6 provided in any of the above embodiments of this application, with the key structure disposed on the panel structure 6.

[0053] In this application, the thickness of the key structure is compressed to the maximum extent. By setting the wrench 2, the top of the force-applying part 20 of the wrench 2 is located below the bottom of the panel outlet 60. Therefore, the force-applying part 20 of the wrench 2 will not occupy the space of the panel outlet 60. Furthermore, the ratio of the distance between the equipment mating point 24 on the wrench 2 and the pin 32 to the distance between the force-applying point and the pin 32 is set to be greater than or equal to a set threshold, so that the key structure can achieve a large force-saving ratio and realize the assisted operation of the large insertion and extraction force plate.
