Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figure 1-13 , the present invention provides a technical solution: a microcomputer integrated protection device, including:

[0041] A housing 1, the housing 1 further includes a front plate, a top plate, a bottom plate and two side plates, and the rear end of the housing 1 is an open end;

[0042] A connecting plate 11, a terminal block 12 is fixedly connected to the connecting plate 11, and a printed circuit board 13 is electrically connected to one side of the terminal block 12;

[0043] A patch panel 14, after being connected to a transmission line, the patch panel 14 is inserted into the terminal block 12;

[0044] A connecting component 2, the connecting component 2 is arranged on the upper and lower sides of the patch panel 14, and the connecting component 2 is used for connecting to the connecting plate 11;

[0045] An ejecting component 3, the ejecting component 3 is used for separating the patch panel 14 from the connecting plate 11;

[0046] The driving component 4, when cooperating with the ejecting component 3, can enable the connecting components 2 on both the upper and lower sides of the socket extension 14 to be separated from the connecting plate 11 simultaneously;

[0047] The button component 5 is arranged on the top of the housing 1. By means of the button component 5, the socket extension 14 can be separated from the connecting plate 11 first, which is convenient for maintenance personnel to pull out. Continuing to use the button component 5 can make the connecting plate 11 separated from the rear end of the housing 1, so as to avoid using the screw fixing method. By adopting the step-by-step pressing method, the socket extension 14 can be removed first and then the connecting plate 11 can be pulled out among the intricate wire arrangements, simplifying the operation.

[0048] The connecting component 2 further includes an insertion plate 21, which is fixedly connected to one side of the wire outlet of the socket extension 14. A first fixing block 22 is fixedly connected to the end of the insertion plate 21, and the first fixing block 22 abuts against the surface of the connecting plate 11. A first slot 23 for the insertion plate 21 to insert is provided on the connecting plate 11. When installing the socket extension 14, after installing the transmission line on the socket extension 14 first, then align the insertion plate 21 on the socket extension 14 with the first slot 23 on the connecting plate 11, and gently push the socket extension 14 with a little external force until the first fixing block 22 is clamped with the inner wall of the connecting plate 11 after the insertion plate 21 completely falls in, so as to achieve the purpose of installing and fixing the socket extension 14. By adopting this method, avoiding using bolts can achieve the purpose of fixing the socket extension 14, and the operation is relatively simple.

[0049] The ejecting component 3 further includes an ejecting plate 31, which is arranged above the first fixing block 22 and fits on the surface of the connecting plate 11. A long plate 32 is fixedly connected to one end of the ejecting plate 31. There are two groups of the long plate 32 and the ejecting plate 31 symmetrically arranged about the horizontal center plane of the connecting plate 11. A first sliding slot 33 for the long plate 32 to slide is provided on the connecting plate 11. By driving the long plate 32 to move along the first sliding slot 33 through the driving component 4, the long plate 32 can drive the ejecting plate 31 to separate the first fixing block 22 from the inner wall of the connecting plate 11, thus facilitating the maintenance personnel to remove the socket extension 14.

[0050] The driving component 4 further includes a gear 41. A connecting shaft 42 is fixedly connected between the long plates 32 of the connecting plate 11, and the connecting shaft 42 is rotatably connected to the gear 41. A tooth 43 is connected to the opposite side of the long plate 32, and the long plate 32 is meshed with the gear 41 through the tooth 43. By means of the button component 5, the upper long plate 32 can be moved downward along the first sliding slot 33. Since the tooth 43 on the side wall of the long plate 32 is meshed with the gear 41, the upper long plate 32 will drive the gear 41 to rotate during the movement, and at the same time, the lower long plate 32 will move upward along the first sliding slot 33 driven by the gear 41, so as to achieve the purpose of pushing out the first fixing block 22 from the inner wall of the connecting plate 11 from both the upper and lower sides simultaneously.

[0051] A connecting plate 11 is fixedly connected with a guiding column 45 in a first chute 33. A long plate 32 is slidably connected with the guiding column 45. A first spring 44 is arranged on the outer wall of the guiding column 45. One end of the first spring 44 abuts against the long plate 32, and the other end of the first spring 44 abuts against the inner wall of the first chute 33 of the connecting plate 11. The long plate 32 moves more stably under the guidance of the guiding column 45. After being compressed, the elastic potential energy generated by the first spring 44 can drive the long plate 32 to reset.

[0052] The button assembly 5 further includes a pushing part 51. The upper end of the pushing part 51 is fixedly connected with a pressing plate 53. A through groove 52 for the pushing part 51 to slide is formed in the upper side top plate of the housing 1. A second fixing block 54 for inserting into the through groove 52 is fixedly connected to one side of the ejecting plate 31. Before installing the wiring board 14, the connecting plate 11 needs to be inserted into the rear end of the housing 1 first. During the insertion process, the second fixing block 54 drives the long plate 32 to move towards each other under the extrusion of the top plate and the bottom plate. When the connecting plate 11 abuts against the housing 1, under the action of the first spring 44, through the reset of the long plate 32, the second fixing block 54 will be inserted into the through groove 52. At this time, after the connecting plate 11 and the housing 1 are installed and fixed, the wiring board 14 can be inserted.

[0053] Two limiting columns 61 are symmetrically and fixedly connected to the bottom of the pressing plate 53. Limiting grooves 63 for the limiting columns 61 to slide are formed in the top plate of the housing 1. A second spring 62 is arranged on the outer wall of the limiting column 61. The top end of the second spring 62 is fixedly connected to the pressing plate 53, and the bottom end of the second spring 62 is fixedly connected to the inner wall of the top plate of the housing 1. Maintenance personnel can gradually press the pressing plate 53, so that the pressing plate 53 drives the pushing part 51 to move downward along the through groove 52, thereby driving the pushing part 51 to drive the second fixing block 54 to move. During the moving process, the second fixing block 54 drives the ejecting plate 31 to first eject the first fixing block 22. At this time, the maintenance personnel can take out the wiring board 14, and continue to press until the pressing plate 53 drives the pushing part 51 to separate the second fixing block 54 from the housing 1, and finally it is convenient for the maintenance personnel to pull out the connecting plate 11.

[0054] A finger plate 71 is arranged at the front end of the pressing plate 53. Sliding rods 72 are symmetrically and fixedly connected to both sides of the finger plate 71. A second chute 73 for slidably connecting with the sliding rods 72 is formed in the pressing plate 53. A stepped groove 74 is formed in the top plate of the housing 1 at the position of the finger plate 71. When it is necessary to press the pressing plate 53, the finger plate 71 needs to be slid along the direction of the sliding rods 72 first, so that the finger plate 71 is separated from the stepped groove 74. At this time, the pressing plate 53 can be pressed without being blocked by the stepped groove 74. This design can avoid the risk of accidental touch.

[0055] A magnetic block 75 is fixedly connected to the top plate of the casing 1 at the stepped groove 74. The finger plate 71 is made of a magnetic material, specifically an iron material. The finger plate 71 made of iron can be adsorbed by the magnetic block 75, and maintenance personnel need to apply a little external force to separate the finger plate 71 from the stepped groove 74, thus increasing the safety against accidental touch.

[0056] The insertion plate 21 is perpendicular to the wiring board 14, and the first slot 23 is inclined. By designing the first slot 23 to be inclined, during the insertion process of the insertion plate 21, it will shift under the drive of the inclined first slot 23 in the shape of a groove, thus generating a certain elastic potential energy. When the ejector plate 31 ejects the first fixed block 22, maintenance personnel apply a little external force to pull out the wiring board 14 outward. During the process of the insertion plate 21 recovering its deformation, it will drive the wiring board 14 to pop out outward, thus facilitating the maintenance personnel to remove the wiring board 14.

[0057] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0058] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
