Description

Technical Field

[0001] The present invention relates to the technical field of interface devices, in particular to a field configuration interface device for communication equipment. Background Art

[0002] Communication equipment includes wired communication equipment and wireless communication equipment suitable for industrial control environments. Among them, wired communication equipment refers to equipment that can perform serial communication, professional bus communication, industrial Ethernet communication, and conversion between various communication protocols in industrial sites. When using communication equipment for communication, interface configuration is required. When the connector of the connecting wire is compatible with the connector of the communication equipment, the connector of the connecting line is directly connected to the connector of the communication equipment; when the connector of the connecting wire is not compatible with the connector of the communication equipment, the connector of the connecting wire needs to be discarded, and then the connecting wire is directly connected to the wiring trough of the communication equipment.

[0003] After the connection between the connecting wire and the communication equipment is completed, the connecting wire needs to be fixed to prevent the connecting wire from falling off. The traditional fixing method is to prevent the connecting wire from falling off by increasing the friction at the joint. Preventing falling off by friction requires a large friction force, which makes it difficult to plug and unplug the joint. In addition, the joints of different connecting wires have certain differences in appearance, which also causes the friction between the two to not necessarily meet the use requirements. In addition, when the connecting wire is directly used to connect to the wiring duct of the communication equipment, the prior art is to clamp the connecting wire with a clamp to prevent it from falling off. Since the clamp is close to the wiring duct, when connecting the connecting wire to the wiring duct, the interference of the clamp makes it difficult to connect the connecting wire to the wiring duct.

[0035] Embodiment:

[0036] Please refer to Figures 1-12 , the present invention provides a technical solution: a field configuration interface device for a communication device, including a communication device 4. In order to prevent the clamp 7 from blocking the display and controller of the communication device 4, the communication device 4 is slightly adjusted in this device. The display and controller of the communication device 4 are arranged on the left side of the communication device 4, and the cable trough and connector of the communication device 4 are arranged on the front side of the communication device 4. An outer frame 1 is sleeved outside the communication device 4. The outer frame 1 is composed of square columns and mainly covers the ridge lines on the boundary of the communication device 4. Such an outer frame 1 will not affect the normal heat dissipation of the communication device 4. A directional sliding plate 8 is movably connected to the front side of the outer frame 1. A transfer bracket 5 is connected to the front side of the directional sliding plate 8. A support bottom plate 6 is arranged above the transfer bracket 5. The support bottom plate 6 has different heights and can select a support bottom plate 6 with a different height according to the use requirements. A clamp 7 is movably connected above the support bottom plate 6. The sliding of the directional sliding plate 8 can drive the clamp 7 to slide, so that the clamp 7 can clamp connection wires at different positions;

[0037] On the front side of the body of the outer frame 1, a guiding gear groove 9 is provided. The guiding gear groove 9 is arranged in a T shape, and a gear surface is provided on one side of the guiding gear groove 9. The directional sliding plate 8 includes a guiding plate 81, which is also arranged in a T shape. The guiding plate 81 is installed inside the guiding gear groove 9. The guiding plate 81 can slide left and right. A return spring 89 is installed in the inner cavity of the guiding plate 81. One end of the return spring 89 is connected with a gear block 84. When pressing the gear block 84, the gear block 84 can be pressed into the inner cavity of the guiding plate 81. After stopping pressing, the return spring 89 will push the gear block 84 to extend out of the guiding plate 81. At this time, the gear surface of the gear block 84 meshes with the gear surface of the guiding gear groove 9;

[0038] The fixture 7 includes a lower clamping plate 71 and an upper clamping plate 73. V-shaped grooves 75 are provided on the upper side of the body of the lower clamping plate 71 and the lower side of the body of the upper clamping plate 73. The two V-shaped grooves 75 correspond to each other. By approaching the two V-shaped grooves 75, the connecting wire can be squeezed. By increasing the squeezing force, the friction force can be increased, and then the connecting wire can be prevented from falling off by increasing the friction force. A locking hole 76 is provided on the upper side of the body of the lower clamping plate 71. A clamping device 88 is arranged inside the locking hole 76. A gear bar 74 is provided on the lower side of the upper clamping plate 73. The teeth on the gear bar 74 are arranged in a sawtooth shape. The gear bar 74 corresponds to the locking hole 76. The clamping device 88 is used to prevent the gear bar 74 from automatically retracting. The clamping device 88 includes a pressing member 881, a clamping member 882 and a thrust spring 883. The clamping member 882 is hinged to the lower clamping plate 71. A limiting groove is provided in the inner cavity of the locking hole 76, which is used to limit the rotation angle of the clamping member 882. The two ends of the thrust spring 883 are respectively connected with the lower clamping plate 71 and the clamping member 882, and this connection point is located below the hinge point of the clamping member 882. One end of the pressing member 881 is in contact with the clamping member 882, and this contact point is located above the hinge point of the clamping member 882. The other end of the pressing member 881 extends out of the lower clamping plate 71. During the downward movement of the gear bar 74, the clamping member 882 will get stuck in the gap between the teeth of the gear bar 74. However, during the downward movement of the gear bar 74, the clamping member 882 will be squeezed, causing its lower end to rotate towards the side of the thrust spring 883, that is, the clamping member 882 will not interfere with the downward movement of the gear bar 74. When the gear bar 74 moves upward, the gear bar 74 drives the lower end of the clamping member 882 to rotate towards the side away from the thrust spring 883. At this time, the clamping member 882 will be limited by the limiting groove and cannot rotate, thereby preventing the gear bar 74 from moving upward, and thus preventing the lower clamping plate 71 and the upper clamping plate 73 from separating. When it is necessary to remove the upper clamping plate 73, the pressing member 881 can be pressed. At this time, the pressing member 881 pushes the lower end of the clamping member 882 to rotate towards the side close to the thrust spring 883, so that the clamping member 882 is separated from the gear bar 74, so that the gear bar 74 can move upward;

[0039] The support base plate 6 includes an adjustment plate 61. An adjustment groove 62 is formed on the upper side of the body of the adjustment plate 61. A clamping device 88 is also provided inside the adjustment groove 62. The clamping member 882 is hinged to the adjustment plate 61. A limiting groove is also formed inside the adjustment groove 62. Both ends of the thrust spring 883 are connected to the adjustment plate 61 and the clamping member 882 respectively, and this connection point is located at the rear side of the hinge point of the clamping member 882. One end of the pressing member 881 is in contact with the clamping member 882, and this contact point is located at the front side of the hinge point of the clamping member 882. The other end of the pressing member 881 extends out of the adjustment plate 61. A gear plate 72 is provided on the lower side of the lower clamping plate 71. The gear surface of the gear plate 72 is also formed into a serrated shape. The clamping member 882 corresponds to the gear plate 72, and the gear plate 72 corresponds to the adjustment groove 62. When the gear plate 72 moves backward, the clamping member 882 will not interfere with the movement of the gear plate 72. When the gear plate 72 moves forward, the clamping member 882 will be stuck into the gear plate 72, thereby prohibiting the gear plate 72 from moving backward.

[0040] A transfer base 82 is connected to the front side of the guide plate 81. A transfer groove 83 is formed on the front side of the body of the transfer base 82. The transfer groove 83 is formed into a T shape. A clamping device 88 is also installed inside the transfer groove 83. The clamping member 882 is hinged to the transfer base 82. A limiting groove is formed in the inner cavity of the transfer groove 83 for limiting the rotation angle of the clamping member 882. Both ends of the thrust spring 883 are connected to the transfer base 82 and the clamping member 882 respectively, and this connection point is located at the lower side of the hinge point of the clamping member 882. One end of the pressing member 881 is in contact with the clamping member 882, and this contact point is located at the upper side of the hinge point of the clamping member 882. The other end of the pressing member 881 extends out of the transfer base 82. The transfer bracket 5 includes a transfer plate 51. The transfer plate 51 is also formed into a T shape. The transfer plate 51 is adapted to the transfer groove 83. A fixed clamping groove 52 is formed on the outer side of the body of the transfer plate 51. The fixed clamping groove 52 corresponds to the clamping member 882. The transfer plate 51 can be prevented from automatically moving upward by the clamping member 882. Since the connectors on the connecting wires have different shapes, some connectors are longer. The separable connection between the transfer bracket 5 and the directional sliding plate 8 can facilitate the replacement of the transfer bracket 5 with different lengths, thereby facilitating the fixing of the connecting wires with connectors of different lengths.

[0041] A U-shaped frame 53 is hinged to the front side of the adapter board 51. The U-shaped frame 53 can rotate. When connecting the connecting wire to the communication device 4, the U-shaped frame 53 can be rotated to move the U-shaped frame 53 away from the connector and the wire trough of the communication device 4, thereby avoiding interference with the docking of the connecting wire. After the connecting wire is docked, the U-shaped frame 53 is rotated back to its original position. A support member 54 is hinged to the front side of the adapter board 51. A support groove is provided on the lower side of the body of the U-shaped frame 53. The other end of the support member 54 corresponds to the support groove. The U-shaped frame 53 is supported by the support member 54 to prevent the U-shaped frame 53 from rotating by itself. A reinforcing rod 56 is connected to the inner side of the U-shaped frame 53. The reinforcing rod 56 is used to increase the stability of the U-shaped frame 53. At the same time, the reinforcing rod 56 is also used to support the support base plate 6, and thus can also increase the stability of the support base plate 6. Positioning card slots 55 are provided on the bodies of the U-shaped frame 53 and the reinforcing rod 56. Card plates 63 are provided on the front and rear sides below the adjusting plate 61. A card slot is provided on the body of the card plate 63. The card slot is stuck on the outside of the positioning card slot 55 to prevent the support base plate 6 from moving. A cover plate 64 is hinged to the lower side of the front card plate 63. The upper side of the rear end of the cover plate 64 is connected to the rear card plate 63. Here, it can be connected by a buckle or a bolt, so as to facilitate the disassembly and assembly of the support base plate 6.

[0042] A protruding block 86 is provided on the front side of the gear block 84. A rotatable pressing plate 87 is installed inside the directional slide plate 8. A pressing button 85 is inserted into the body of the directional slide plate 8. One side of the pressing button 85 extending into the directional slide plate 8 is in contact with the pressing plate 87. The other side of the pressing plate 87 is in contact with the protruding block 86. When the pressing button 85 is pressed, the pressing button 85 will press the protruding block 86 through the pressing plate 87, so that the protruding block 86 drives the gear block 84 to move toward the side of the return spring 89. After the gear block 84 is completely retracted into the guide plate 81, the guide plate 81 can slide left and right.

[0043] A protective baffle 3 is hinged to the upper front side of the outer frame 1. A hook 2 is movably connected to the upper side of the outer frame 1. A pull ring is provided on the upper side of the protective baffle 3. The other end of the hook 2 is detachably connected to the pull ring. The protective baffle 3 is pulled by the hook 2 to be located above the fixture 7, so as to prevent foreign objects from hitting the fixture 7 during the falling process.

[0044] A V-shaped anti-slip pad is provided inside the V-shaped groove 75. The V-shaped anti-slip pad is made of rubber material. On the one hand, the V-shaped anti-slip pad can increase the friction force to prevent the connecting wire from falling off. On the other hand, the rubber material is relatively soft and can also prevent the connecting wire from being clamped and damaged.

[0045] Working principle: Insert the adapter plate 51 of the adapter bracket 5 into the adapter slot 83 of the directional slide plate 8 to complete the connection between the adapter bracket 5 and the directional slide plate 8. Then, snap the positioning plate 63 of the support base plate 6 onto the positioning card slot 55 of the adapter bracket 5 and connect the cover plate 64 to the positioning plate 63, thereby completing the connection between the support base plate 6 and the adapter bracket 5. Subsequently, dock the connection wire with the communication device 4. After the docking is completed, move the directional slide plate 8. The directional slide plate 8 drives the support base plate 6 to move through the adapter bracket 5 until the support base plate 6 is located below the connection wire. Then, insert the gear plate 72 of the fixture 7 into the adjustment slot 62 of the support base plate 6. When there is a connector on the connection wire, make the fixture 7 fit with the connector of the connection wire. When there is no connector on the connection wire, make the fixture 7 flush with the support base plate 6. Then, insert the gear bar 74 of the upper clamping plate 73 into the locking hole 76 to complete the clamping of the connection wire.
