[0030] 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.

[0031] Referring to Figures 1-8 , an OTN device according to the present invention includes an OTN equipment cabinet 1. A plurality of brackets 11 are arranged in the OTN equipment cabinet 1. A circuit board box 2 is slidably mounted on the brackets 11. A wire electrode pin 22 is arranged on the circuit board box 2. A circuit board connection plate 12 is installed at the rear side inside the OTN equipment cabinet 1. A card shaft 21 is arranged below the circuit board box 2. A sliding seat 3 is arranged on the brackets 11. A clamping mechanism for clamping the card shaft 21 is arranged on the sliding seat 3. The clamping mechanism includes a stopper 31 arranged on the sliding seat 3. A movement mechanism for driving the sliding seat 3 to move is arranged on the brackets 11. The movement mechanism includes a slide block 34 installed on the brackets 11. The slide block 34 drives the sliding seat 3 to slide on the brackets 11, driving the wire electrode pin 22 on the circuit board box 2 to fit with the circuit board connection plate 12, and automatically connecting the circuit board box 2 with the circuit on the OTN equipment cabinet 1;

[0032] In the initial state, the circuit board box 2 is installed in the OTN equipment cabinet 1, and the wire pole feet 22 on the circuit board box 2 are in contact with the line connection plate 12. When replacing the circuit board box 2, the old circuit board box 2 is pushed into the OTN equipment cabinet 1, and the motion mechanism drives the sliding seat 3 to slide on the bracket 11 and is pushed out under the action of the motion mechanism. The wire pole feet 22 on the old circuit board box 2 are out of contact with the line connection plate 12, and the old circuit board box 2 is pulled out of the bracket 11, and the card shaft 21 on the new circuit board box 2 is docked with the sliding seat 3. At this time, the block 31 clamps and fixes the card shaft 21, and the OTN equipment cabinet is pushed into place. 1, and stop pushing the circuit board box 2 until a click sound is heard. At this time, the wire pole feet 22 on the circuit board box 2 are in close contact with the line connection plate 12, and the circuit board box 2 is prevented from sliding in the OTN equipment cabinet 1 through the resistance of the stopper 31 and the clamping shaft 21, thereby ensuring the close contact between the wire pole feet 22 and the line connection plate 12, facilitating the connection of the internal lines, and avoiding the trouble of internal wiring and fixing screws and nuts when installing the circuit board. At the same time, the circuit board box 2 is driven to slide on the bracket 11 through the action of the motion mechanism on the sliding seat 3, thereby facilitating the installation and disassembly of the circuit board box 2.

[0033] The clamping mechanism also includes a connecting groove 32 arranged on the sliding seat 3. The connecting groove 32 is an unclosed circular groove. Two relative blocks 31 are installed at the outer opening of the connecting groove 32. There is a certain gap between the two relative blocks 31, which is convenient for the block 31 to resist and produce a certain deformation when the card shaft 21 is driven by an external force. After the card shaft 21 enters the connecting groove 32, the block 31 restores the initial relative state. It should be pointed out that the block 31 is a plastic material. After the card shaft 21 is fitted with the connecting groove 32, the block 31 resists the card shaft 21 to a certain extent to prevent the card shaft 21 from being separated from the connecting groove 32.

[0034] The moving mechanism further includes a sliding groove 33 formed in the bottom surface of the sliding seat 3. A sliding seat 34 is slidably installed in the sliding groove 33.

An installation block 112 having a shape different from that of the return groove A is provided inside the return groove A. A front sharp angle 1121 is provided on the front side of the installation block 112. A rear sharp angle 1122 is provided on the rear side of the installation block 112. A groove 1123 is provided on the right side of the installation block 112. The size of the groove 1123 is adapted to the shape of the sliding shaft 341. A front rounded corner 113 is provided on the front side of the return groove A. A rear rounded corner 114 is provided on the rear side of the return groove A. The front sharp angle 1121 and the front rounded corner 113 are offset by a certain angle in the front-rear direction and the front sharp angle 1121 is biased to the left of the front rounded corner 113. The rear sharp angle 1122 and the rear rounded corner 114 are offset by a certain angle in the front-rear direction and the rear sharp angle 1122 is biased to the right of the rear rounded corner 114. The sliding seat 3 is connected to the rear side surface of the sliding groove 111 through a first elastic member 13. The first elastic member 13 is always in a compressed state. The first elastic member 13 drives the sliding seat 3 to slide forward. The sliding shaft 341 ensures that the sliding seat 3 and the sliding groove 111 are not separated. At the same time, the front sharp angle 1121, the front rounded corner 113, the rear sharp angle 1122, and the rear rounded corner 114 offset by a certain angle ensure that the movement path of the sliding shaft 341 will not rotate. The first elastic member 13 is preferably a spring. When the sliding shaft 341 moves to the rear side and abuts against the groove 1123, the installer can hear a clicking sound. At this time, the wire electrode pin 22 on the circuit board box 2 is in close contact with the circuit connection board 12. When disassembling the circuit board box 2, continue to push the circuit board box 2 backward. The sliding shaft 341 passes over the rear sharp angle 1122 and moves to the frontmost position under the action of the first elastic member 13 pushing the sliding seat 3. Here, the circuit board box 2 can be directly pulled out for disassembly and replacement.

The rear end of the shielding cover 14 is connected to a second elastic member 15, and the second elastic member 15 is an elastic telescopic layer and the elastic telescopic layer is always in In the compressed state, when the shielding cover 14 slides to the frontmost position of the circuit connecting plate 12, the shielding cover 14 just completely covers the electrode sheet above the circuit connecting plate 12. When the circuit board box 2 is installed, the wire pole feet 22 on the circuit board box 2 contact the shielding cover 14 and drive the shielding cover 14 to move backward, so that the wire pole feet 22 fit with the electrode sheet, thereby connecting the circuit. When the circuit board box 2 is disassembled, the shielding cover 14 moves forward along the direction of the shielding groove 121 under the action of the second elastic member 15, shields the electrode sheet, and improves the neatness of the electrode sheet.
