Technical Field

[0001] The invention relates to a communication controller. Background Art

[0002] A communication controller refers to a communication interface device located between the data circuit and the host in a data communication system and used to control data transmission, referred to as CCU.

[0003] Communications controllers manage the input and output of data to a host or computer network. They can be complex front-end mainframe computer interfaces or simple devices such as multiplexers, bridges, and routers. These devices convert the computer's parallel data into serial data for transmission on the communications line and perform all necessary control functions, error detection, and synchronization.

[0004] The communication controller is usually connected with multiple data lines. During the use of the communication controller, the data line interface may become loose or even detached due to external factors, thus affecting the communication. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 7 As shown, a communication controller 100 includes: a controller body 10. A plurality of data interfaces 11 are provided at the rear end of the controller body 10. The plurality of data interfaces 11 can be interfaces of the same type or interfaces of different types. The data line is inserted into the data interface 11 to realize communication.

[0032] As a preferred embodiment, the communication controller 100 further includes: an outer sliding sleeve 20, a fixed plate 31, a movable plate 32, a data line limiting plate 33, a data line lower clamping block 34, a data line upper clamping block 35 and a reset torsion spring.

[0033] The outer sleeve 20 is slidably mounted on the outer periphery of the controller body 10. The controller body 10 is roughly in the shape of a cube. The inner wall surface of the outer sleeve 20 fits the outer surface of the controller body 10. The outer sleeve 20 is a rectangular sleeve.

[0034] The movable plate 32 is rotationally connected to the controller body 10. The return torsion spring connects the movable plate 32 and the controller body 10. The return torsion spring applies a force that causes the movable plate 32 to rotate relative to the controller body 10.

[0035] The fixed plate 31 is fixed to the controller body 10. Specifically, the movable plate 32 and the fixed plate 31 are both at the rear end of the controller body 10. The data line limit plate 33 and the data line clamping block 34 are fixed to the fixed plate 31. The data line clamping block 35 is slidably connected to the movable plate 32. The data line limit plate 33 arranges and arranges the data lines, and lays the data lines in a row. Since the arrangement of the data interfaces on the controller body 10 is irregular, the data line limit plate 33 can be used to arrange the data lines for easy management of the data lines and to lock the data lines to prevent the data lines from loosening. Specifically, the data line limit plate 33 is formed with a plurality of threading grooves 331 for limiting the position of the data lines. The plurality of threading grooves 331 are arranged in a row of the same height. The notch of the threading groove 331 faces upward. The user inserts the data line from the notch into the threading groove 331.

[0036] The number of the data line limiting plates 33 is 2. The two data line limiting plates 33 are located on both sides of the data line lower clamping block 34 and the threading grooves 331 of the two data line limiting plates 33 are aligned one by one. The data lines are limited by the two data line limiting plates 33, and multiple data lines are laid out in a row in the area between the two data line limiting plates 33.

[0037] The outer sliding sleeve 20 has a locking position and an unlocking position. The outer sliding sleeve 20 slides between the locking position and the unlocking position. The outer sliding sleeve 20 can lock the movable plate 32, thereby maintaining the position of the movable plate 32.

[0038] When the outer sliding sleeve 20 is in the locking position, the outer sliding sleeve 20 contacts the movable plate 32 to prevent the movable plate 32 from rotating away from the fixed plate 31 , and the data line clamping block 35 and the data line lower clamping block 34 clamp the data line from both sides.

[0039] When the outer sleeve 20 is in the unlocking position, the outer sleeve 20 is out of contact with the movable plate 32, the movable plate 32 can rotate away from the fixed plate 31, and the data line clamping block 35 is away from the data line lower clamping block 34 to release the data line.

[0040] Specifically, when the outer sleeve 20 moves from the unlocked position to the locked position (moving rightward in the reference figure), the inner wall surface of the outer sleeve 20 contacts the movable plate 32 to overcome the elastic force of the return torsion spring and push the movable plate 32 to rotate so that the data line clamping block 35 is close to the data line clamping block 34.

[0041] When the outer sleeve 20 moves from the locked position to the unlocked position (moving leftward in the reference figure), the inner wall surface of the outer sleeve 20 breaks away from the contact with the movable plate 32, and the reset torsion spring pushes the movable plate 32 to rotate so that the data line clamping block 35 moves away from the data line clamping block 34.

[0042] As a specific implementation, the direction in which the clamping block 35 on the data line slides relative to the movable plate 32 is perpendicular to the rotation axis of the movable plate 32 relative to the controller body 10. The sliding direction of the outer sleeve 20 is perpendicular to the rotation axis of the movable plate 32 relative to the controller body 10. When the outer sleeve 20 is in the locked position, the direction in which the clamping block 35 on the data line slides relative to the movable plate 32 is perpendicular to the sliding direction of the outer sleeve 20.

[0043] When in the locked position, the direction of the force exerted by the movable plate 32 on the outer sleeve 20 under the action of the return torsion spring is perpendicular to the sliding direction of the outer sleeve 20, so the outer sleeve 20 will not move from the locked position to the unlocked position under the influence of the force exerted by the return torsion spring on the movable plate 32. The locking can be kept reliable.

[0044] As a preferred embodiment, in order to further maintain the position of being able to stay in the locked position and the unlocked position, the controller body 10 is provided with: a positioning pin 38 and a pin spring 39. The inner wall surface of the outer sleeve 20 is formed with a locking pin hole 381 and an unlocking pin hole 382. The positioning pin 38, the pin spring 39, the locking pin hole 381 and the unlocking pin hole 382 constitute a limiting structure. Specifically, the pin spring 39 applies a force to the positioning pin 38 to push the positioning pin 38 to move. The inner wall surface of the outer sleeve 20 is formed with a locking pin hole 381 and an unlocking pin hole 382 for the positioning pin 38 to be embedded in order to lock the position of the outer sleeve 20. When the positioning pin 38 is located in the locking pin hole 381, the outer sleeve 20 is in the locked position. When the positioning pin 38 is located in the unlocking pin hole 382, ​​the outer sleeve 20 is in the unlocking position. The movement direction of the positioning pin 38 is perpendicular to the sliding direction of the outer sleeve 20. The locking principle of the locked position is the same as that of the unlocked position, and the locked position is used for explanation. When the outer sleeve 20 moves to the locking pin hole 381 to align with the positioning pin 38, the force of the pin spring 39 pushes the end of the positioning pin 38 into the locking pin hole 381. Thereby, the outer sleeve 20 is limited in the locked position. The head of the positioning pin 38 is hemispherical. When the user needs to adjust the position of the outer sleeve 20, the outer sleeve 20 is pulled, and the hole wall of the locking pin hole 381 squeezes the head of the positioning pin 38, and the positioning pin 38 is disengaged from the locking pin hole 381.

[0045] As a preferred embodiment, the communication controller 100 further includes: a reset spring 36. The reset spring 36 is arranged between the clamping block 35 on the data line and the movable plate 32. The movable plate 32 is provided with an upper guide sleeve 37 for guiding the clamping block 35 on the data line to slide. The reset spring 36 is arranged in the upper guide sleeve 37. When in the locked position, the force of the reset spring 36 pushes the clamping block 35 on the data line to move in the direction close to the clamping block 34 on the data line, so that the clamping block 35 on the data line and the clamping block 34 on the data line clamp the data line from both sides to lock the data line and prevent the data line from loosening. As a specific embodiment, the clamping block 34 on the data line is formed with a plurality of grooves for assisting in positioning the data line. The end surface of the clamping block 35 on the data line for contacting the data line is a plane. As an optional embodiment, the end surface of the clamping block on the data line for contacting the data line can also be provided with a groove. Similarly, the top surface of the clamping block 34 on the data line may not be provided with a groove for assisting positioning.

[0046] When the outer sleeve 20 is in the locked position, the outer sleeve 20 surrounds or wraps one end of the data cable interface to provide a certain degree of protection for the data cable interface. The data cable limit plate 33 blocks the sleeve opening of the outer sleeve 20 to a certain extent and also provides a certain degree of protection. A hollow area is formed on the side of the fixed plate 31 close to the controller body 10 to facilitate the connection of the data cable. Specifically, the fixed plate 31 includes a transverse plate portion and two connecting plate portions. The transverse plate portion, the connecting plate portion and the controller body 10 together form a hollow area. The two ends of the transverse plate portion are respectively connected to the controller body 10 through two connecting plate portions. The data cable limit plate 33 and the data cable lower clamping block 34 are fixed to the transverse plate portion. The extension direction of the data cable limit plate 33 and the data cable lower clamping block 34 is parallel to the extension direction of the transverse plate portion.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
