Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of E1 switching protection equipment, in particular to an E1 automatic switching protector. Background Art
[0002] In communication transmission networks such as mobile base stations, E1 automatic switching protectors are used to ensure stable communication transmission. The E1 lines are connected to the main E1 interface and backup E1 interface of the E1 automatic switching protector respectively. When the main E1 line fails, the equipment will automatically switch to the backup E1 line for transmission without damage; when the main E1 line is repaired, the equipment will automatically switch back to the main E1 line for transmission without damage.
[0003] Since one communication line is equipped with two lines, the existing E1 automatic switching protector is connected to more lines. After the lines are combined, they are heavier and put more pressure on the line structure. The E1 automatic switching protector will use a horizontal bar to assist in tightening and fixing the line connectors to improve the stability of the line. However, if a line needs to be plugged in or out, the upward movement of the horizontal bar will also relieve the pressure on other line ports at the same time, which is not conducive to the stability of other connectors. The horizontal bar presses on the line port for plugging and unplugging, increasing the pressure of plugging and unplugging. Utility Model Content

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings. Example 1:
[0031] Please refer to Figures 1 to 6 :
[0032] The utility model proposes an E1 automatic switching protector, comprising: a main switching protection module 1, a rear fixed horizontal frame 2 and a rear fixed block 3. The front hinge of the main switching protection module 1 is rotated with a front operating screen 101. The hinge of the front operating screen 101 is provided with a rotation damping. The front operating screen 101 can be stopped at any angle. The front operating screen 101 displays the on-off status of the connection port of the main switching protection module 1. When performing equipment maintenance, the front operating screen 101 is rotated and tilted upward. When the front operating screen 101 is close to a horizontal angle, it is more convenient for personnel to view and operate from above, especially in cabinets that are vertically stacked. Personnel in the vertical direction need to look straight down for convenient viewing, and the tilted upward front operation screen 101 is more convenient for personnel to look down and operate. The front part of the main switching protection module 1 is provided with two communication ports 102, and the two communication ports 102 are connected to two power lines. The front part of the main switching protection module 1 is provided with two power ports 103, and the power ports 103 are electrically connected to the external power supply through the line. The two power ports 103 are two power lines. The rear spaced array of the main switching protection module 1 is provided with E1 connection ports 104, and the E1 connection ports 104 are arranged in groups of two, one for the main and the other for the backup.
[0033] The rear of the main switching protection module 1 is fitted with a rear fixed cross frame 2 for sliding fit up and down. The head and tail ends of the rear fixed cross frame 2 are fixed with a lower connecting slide pipe 201. The upper part of the lower connecting slide pipe 201 is slidably connected to the upper connecting slide column 202. The head and tail ends of the rear fixed cross frame 2 are fixed with a connecting tension spring 203. The lower connecting slide pipe 201 and the rear of the main switching protection module 1 are connected through sliding connection. The upper connecting slide column 202 and the rear of the main switching protection module 1 are connected through sliding connection. The tail end of the connecting tension spring 203 is fixedly connected to the main switching protection module 1. The rear fixed cross frame 2 slides in opposite directions through the upper connecting slide column 202 and the lower connecting slide tube 201. The support spring 206 supports the head end of the side clip 205 to move and protrude to the inside of the middle groove 204. The rear fixed block 3 is on the inside of the middle groove 204. The bottom plane of the side clip 205 is in contact with the top of the rear fixed block 3. The side clip 205 limits the upward movement of the rear fixed block 3. The rear fixed cross frame 2 and the rear fixed block 3 are hinged and rotatably connected. The lower connecting slide tube 201 and the upper connecting slide column 202 are respectively fixedly connected to the upper and lower rear fixed cross frames 2 at the rear of the main switching protection module 1.
[0034] Furthermore, the rear fixed horizontal frame 2 is provided with middle grooves 204 at intervals, and the rear fixed horizontal frame 2 is provided with side buckles 205 for horizontal sliding on one side of the middle groove 204. A support spring 206 is provided between the side buckle 205 and the rear fixed horizontal frame 2. The support spring 206 pulls the rear fixed horizontal frame 2 and the rear fixed block 3 to move close to the E1 connection port 104, and the V-shaped groove 301 of the upper rear fixed block 3 fits and presses the line connector above the E1 connection port 104, and the V-shaped groove 301 of the lower rear fixed block 3 fits and presses the line connector below the E1 connection port 104. The tightening of the rear fixed block 3 prevents the E1 connection port 104 and the line connector from moving loose.
[0035] Furthermore, a V-shaped groove 301 is provided in the middle of the rear fixing block 3. The V-shaped groove 301 is located on the side of the rear fixing block 3 close to the E1 connection port 104. The side buckle 205 moves to the inside of the rear fixing cross frame 2, and the rear fixing cross frame 2 no longer protrudes and is stuck on the top of the rear fixing block 3. The rear fixing block 3 is rotated upward away from the E1 connection port 104, and the position of the rear fixing cross frame 2 is not affected. The rear fixing block 3 no longer presses the line connector of the E1 connection port 104, which facilitates the connection and plugging operation of the line connector of a single E1 connection port 104 and does not increase the plugging and unplugging resistance of the line connector of the E1 connection port 104. At the same time, it does not affect the pressing operation of the line connector of the E1 connection port 104 by the adjacent rear fixing block 3, and avoids the integrated rear fixing cross frame 2 from pressing multiple E1 connection ports 104. The plugging and unplugging of the line connector of one E1 connection port 104 will drive the rear fixing cross frame 2 to move up and down as a whole, affecting the pressing of other E1 connection ports 104. Example 2:
[0036] On the basis of Example 1, a lower connecting slide tube 201 and an upper connecting slide column 202 are arranged in the middle of the upper and lower rear fixed cross frames 2 for opposite sliding connection. The upper and lower rear fixed cross frames 2 enhance the horizontal anti-bending support force through the lower connecting slide tube 201 and the upper connecting slide column 202.
