Description

Technical Field

[0001] The utility model relates to the field of electronic equipment interface protection, in particular to a safety protection interface device for electronic equipment. Background Art

[0002] A safety protection interface device for electronic equipment is a protective device used to protect electronic equipment when plugging and unplugging cables at the wiring port. It can prevent cables such as cables from being forcibly pulled out when suddenly encountering strong external forces, thereby causing network disconnection, or serious problems such as data transmission failure and loss, which can easily cause serious economic losses.

[0003] At present, switches or other electronic devices with many ports usually do not have safety protection interface devices for electronic devices. Usually, switches contain many ports and are connected to a large number of cables, making it difficult to provide a stable limit for the plugging and unplugging of cables on each port. The anti-drop-off electronic devices disclosed in the prior art have the defects of complex structure and inconvenient operation. For example, CN202021206953.0 discloses a switch for information technology with an anti-drop-off structure, which adopts a first card plate, a first spring, a card block, a stop block, a first card slot, a plug rod, a jack, a handle, and a second spring to achieve an anti-drop-off structure. The structure is complex and inconvenient to operate. Therefore, we urgently need to design a protective device that can be quickly assembled on a switch, is easy to operate, and can provide a stable limit and stop for cables on multiple ports, and can effectively prevent them from being pulled out violently.

[0009] Preferably, the card block and the card slot are respectively provided with mutually matching pin holes; after the card block is embedded in the card slot, a T-shaped pin is inserted into the two penetrating pin holes to fix the support frame.

[0010] Preferably, the number of the hanging rings is multiple, specifically two rows distributed vertically and arranged inversely to each other.

[0011] Preferably, two sliding rods are transversely fixedly arranged inside the support frame; an extension plate is integrally arranged at the rear end of the hanging ring; a sleeve is arranged at the rear end of the extension plate; and the sleeve is sleeved on the sliding rod to form a rotatable connection.

[0012] Preferably, the inner diameter of the hanging ring is larger than the harness portion of the cable and smaller than the end portion of the cable.

[0013] Preferably, the middle part of the L-shaped plate is elastically rotatably arranged on one side of the open end of the hanging ring; a second hinge seat is integrally arranged on one of the cross-sections of the open end of the hanging ring; a second pin rod is integrally arranged in the middle part of the L-shaped plate; the second pin rod is wound around a torsion spring and then sleeved in the second hinge seat, thereby realizing an elastic rotational connection.

[0024] Figure 1-5 An implementation form of the utility model is shown, including:

[0025] A support frame 1 is rotatably arranged outside the cabinet compartment 10; a stopper 20 is arranged in the middle of the support frame 1;

[0026] The hanging ring 2, whose rear end can be rotatably arranged on the supporting frame 1; the front end of the hanging ring 2 is an open end 21;

[0027] The L-shaped plate 3 is elastically rotatably arranged on one side of the open end 21 of the hanging ring 2; the shorter end of the L-shaped plate 3 abuts against the open end 21 of the hanging ring 2; the longer end of the L-shaped plate abuts against the blocking rod 20 laterally to form a limit.

[0028] Working principle: The equipment manager first pushes the switch 101 (or other electronic equipment with multiple ports 102) into one of the compartments 10 of the cabinet to place it stably, and then inserts the cables 103 into the multiple ports 102 on the back of the switch 101. At this time, the rear end of the switch 101 is close to the side of the support frame 1, and then manually flips the hanging ring 2 downward, first pulls the shorter end of the L-shaped plate 3 apart to expose the open end 21 of the hanging ring 2, and then inserts the rear end of the cable 103 from the open end of the hanging ring 2, so that the cable part 104 of the entire cable 103 can be completely inserted into the inner circle of the hanging ring 2, and the cable 103 is fixed. After installation, release the L-shaped plate 3, the L-shaped plate 3 will elastically recover, and its shorter end will abut and block the open end 21 of the hanging ring 2, while the longer end of the L-shaped plate 3 will rotate downward again and abut against the blocking rod 20 to achieve limiting. In this design, since the entire hanging ring has already sleeved the cable 103 in the inner ring, so that the open end of the hanging ring 2 is blocked by the shorter end of the L-shaped plate, if an excessively large external force occurs to drag the cable 103, the end portion 105 of the cable 103 can still be stably abutted and limited in the port 102, and will not be forcibly dragged and directly pulled out, thereby playing an anti-drag protection role.

[0029] In the above technical solution, a first hinge seat 11 is provided on one side of the cabinet compartment 10; a first pin rod 12 matching the first hinge seat 11 is provided on the inner side of the support frame 1; the first pin rod 12 is sleeved in the first hinge seat 11 to form a rotatable connection; a card block 13 is provided on the outer side of the support frame 1; and a card slot 14 matching the card block 13 is provided on the other side of the cabinet compartment 10.

[0030] Working principle: In this design, the entire support frame 1 can be similar to a door-shaped switch structure, so that it is more convenient to fit the switch 101 placed in the cabinet compartment, and the switch pulling operation is more convenient; secondly, by embedding the card block 13 on the outside of the support frame 1 in the card slot 14, it is ensured that the support frame 1 can fit more stably on the cabinet compartment 10 after being buckled and closed.

[0031] In the above technical solution, the block 13 and the slot 14 are respectively provided with mutually matching pin holes 134 ; after the block 13 is embedded in the slot 14 , a T-shaped pin 15 is inserted into the two penetrating pin holes 134 , thereby fixing the support frame 1 .

[0032] Working principle: After the T-shaped pin 15 is inserted into the two pin holes 134, it ensures that the entire support frame 1 can be stably fixed on the outside of the cabinet compartment 10. At the same time, the T-shaped pin 15 is easy to pull out, which facilitates the opening of the entire support frame 1 and improves the applicability of the device.

[0033] In the above technical solution, the number of the hanging rings 2 is multiple, specifically two rows distributed vertically and arranged inversely to each other.

[0034] Working principle: In this design, since the wiring ports 102 of the rear panel of most switches 101 are arranged in two rows inverted, multiple hanging rings 2 are also arranged in two rows inverted, which can be consistent with the ports 102 on the rear end of the switch 101, making it more convenient to connect the connected cables 103, ensuring that the overall device is more stable.

[0035] In the above technical solution, two sliding rods 16 are fixedly arranged transversely inside the support frame 1; an extension plate 21 is integrally arranged at the rear end of the hanging ring 2; a sleeve 22 is arranged at the rear end of the extension plate 21; the sleeve 22 is sleeved on the sliding rod 16 to form a rotatable connection.

[0036] Working principle: In this design, when the entire hanging ring 2 is clipped onto the cable 103, the shorter end of the L-shaped plate can be pulled apart first, and then the entire hanging ring 2 can be rotated from the outside to the inside, and then the cable 103 can be clipped in through the open end 21 below the hanging ring 2. This assembly method is more convenient. At the same time, the lateral spacing of multiple ports 12 at the rear end of different types of switches 101 is different. Through the sleeve 22 and the slide rod 16, multiple hanging rings 2 can also be slid laterally, and the spacing can be fine-tuned to ensure alignment with the wiring ports 12 at different spacings, which significantly improves the applicability of the device.

[0037] In the above technical solution, the inner diameter of the hanging ring 2 is larger than the wire harness portion 104 of the cable 103 and smaller than the end portion 105 of the cable.

[0038] Working principle: In this design, since the inner diameter of the hanging ring 2 is larger than the wiring harness part 104 of the cable 103, when the shorter end of the L-shaped plate 3 is pulled apart, the cable can be stably inserted into the inner circle of the hanging ring 2. At the same time, since the inner diameter of the hanging ring 2 is larger than the end part 105 of the cable, the cable 103 can be stably restricted from being forcibly pulled out, thereby playing a protective role.

[0039] In the above technical solution, the middle part of the L-shaped plate 3 is elastically rotatably arranged on one side of the open end 21 of the hanging ring 2; a second hinge seat 31 is integrally arranged on one of the cross sections of the open end 21 of the hanging ring 2; a second pin rod 32 is integrally arranged in the middle part of the L-shaped plate 3; the second pin rod 32 is wound with a torsion spring and then sleeved in the second hinge seat 31, thereby realizing an elastic rotation connection.

[0040] Working principle: In this design, due to the elastic force of the torsion spring, the shorter end of the L-shaped plate 3 will always fit and seal on the open end 21 of the hanging ring 2. When the cable 103 needs to be inserted or removed, the shorter end of the L-shaped plate 3 only needs to be moved and pulled open. After letting go, the shorter end of the L-shaped plate 3 will elastically fit onto the open end 21 of the hanging ring 2 again to achieve sealing. This makes the operation more convenient and quick, and improves the efficiency of the clamping and assembly of the cable 103.

[0041] In the above technical solution, strip grooves 201 are provided on the upper and lower sides of the blocking rod 20; the longer end of the L-shaped plate 3 is laterally embedded in the strip groove 201 to form a blocking limit.

[0042] Working principle: In this design, due to the elasticity of the torsion spring, the longer end of the L-shaped plate 3 will be directly embedded in the strip groove 201 laterally at the beginning, thereby forming a limiting state for the entire L-shaped plate together with the hanging ring 2. When the cable 103 encounters external force dragging, the end part 105 of the cable 103 can be stably clamped and restricted in the hanging ring 2, thereby achieving the limiting effect; at the same time, when the cable 103 needs to be taken out, it is only necessary to rotate the L-shaped plate 3 to make the longer end of the L-shaped plate 3 disengage from the entire strip groove 201. At the same time, the shorter end of the L-shaped plate 3 also disengages from the open end 21 of the hanging ring 2. After the entire hanging ring 2 is flipped up, the cable 103 can be taken out. The operation is convenient and the cable 103 is easy to assemble.
