DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-6 As shown, it includes a communication module 10, a card plug-in assembly and a contact assembly, both of which are located inside the communication module 10, wherein the card plug-in assembly is detachable, and the contact assembly is fixedly installed, the interior of the communication module 10 is hollow, a slide groove 12 is provided on one side end face of the communication module 10, and a limiting groove 11 is also provided inside the communication module 10, and the limiting groove 11 passes through the slide groove 12.

[0027] The card insertion assembly includes a card tray 20 that slides in the communication module 10, and two card slots are provided on one end face of the card tray 20. The card tray 20 is also provided with a protective slide 25, a main abutment block 24 and a limit plate 21, wherein the protective slide 25 slides in the communication module 10, and one end face of the main abutment block 24 is arc-shaped. A protective cavity 23 is provided inside the card tray 20, and the protective slide 25 slides in the protective cavity 23. The limit plate 21 and the main abutment block 24 are respectively fixed at both ends of the protective slide 25, wherein the limit plate 21 slides in the limit groove 11, and the card insertion assembly can be limited by the limit plate 21 in the limit groove 11 to prevent it from falling. A shift block 22 is fixed on the end face of the limit plate 21 away from the card tray 20, and a plurality of serrations are provided on the end face of the shift block 22. The serrations can conveniently push the shift block 22 to drive the protective slide 25 to slide.

[0028] At least three grooves are provided on one end face of the protection slide plate 25, and at least five positioning protrusions 27 are fixed on the inner wall of the protection cavity 23. The distance between two adjacent grooves is equal to the distance between two adjacent positioning protrusions 27. When the protection slide plate 25 is moved, the protection slide plate 25 can be kept stationary in a fixed position by limiting the position between the grooves and the positioning protrusions 27, thereby avoiding the phenomenon of its resetting. Moreover, the current position of the protection slide plate 25 can be judged by the damping feeling between the positioning protrusions 27 and the grooves.

[0029] One side end face of the card tray 20 is provided with two symmetrically arranged card slots, in which a communication card 40 is detachably installed. A plurality of card slot protrusions 26 are fixed on the inner wall of one side of the card slot, and the card slot protrusions 26 can make the communication card 40 more stably installed and not easy to fall off.

[0030] The contact assembly includes a card insertion box 30, and the card insertion box 30 is provided with two rotatably connected rotating shafts 31 inside, and at least two contact pins 32 are fixed on the rotating shaft 31, and a secondary abutment block 33 is fixed to the end face of each contact pin 32 away from the rotating shaft 31. A torsion spring is installed on each rotating shaft 31, and the torsion spring enables the contact pin 32 to be more tightly connected to the interface of the communication card, and after the secondary abutment block 33 is not restricted, the contact pin 32 can be reset under the action of the torsion spring, and one end face of the secondary abutment block 33 is also arc-shaped, and the materials of the secondary abutment block 33 and the main abutment block 24 are both insulating materials. Through the arc surface setting of the secondary abutment block 33 and the main abutment block 24, the dial block 22 can be pushed to make the arc surface of the main abutment block 24 contact the arc surface of the secondary abutment block 33, thereby abutting the secondary abutment block 33 to drive the corresponding contact pin 32 to rotate to the side away from the card tray 20, and the contact can be disconnected at this time. The connection between the contact pin 32 and the communication card 40 can achieve the effect of direct mechanical card removal, which can quickly respond in more urgent situations. When the emergency situation is resolved, it is only necessary to push the dial block 22 to disengage the main abutment block 24 from the abutment against the secondary abutment block 33, so that the contact pin 32 can be connected to the communication card 40 again. A cavity is provided inside the card box 30, and two groups of movable holes 35 are provided on the end face of the card box 30 away from the card tray 20. The movable holes 35 correspond to the contact pins 32 one by one. A wire 34 is fixed to one end face of each contact pin 32, and the wire 34 moves in the movable hole 35, and the other end of the wire 34 is connected to other electronic components in the communication module 10. Through the movable wire 34, the contact pin 32 will not be affected during the rotation process, and all corresponding contact pins 32 are connected through the secondary abutment block 33, so that the contact pins 32 can rotate synchronously.

[0031] Working principle: When in use, the two communication cards 40 can be placed in the card slots of the card tray 20 first, and then the card assembly can be inserted into the card box 30 until the limit plate 21 is in the limit slot 11. At this time, the connection port on the communication card 40 can contact the corresponding contact pin 32, and the communication card 40 can be used normally. In case of emergency (such as the communication device is invaded or the communication device has a short circuit), the protection slide plate 25 can be driven by the dial block 22 to move the main abutment block 24. The movement of the main abutment block 24 will abut one of the secondary abutment blocks 33, so that the current contact pin 32 is disconnected from the communication card 40 to protect the corresponding communication card 40, which greatly reduces the loss. When the emergency is resolved, the dial block 22 can be dialed again to reset it, so that the protected communication card 40 can be connected again so that it can work directly.

[0032] When the card assembly needs to be removed, the shifting block 22 needs to be shifted to the middle position of the slide slot 12 , and then the entire card assembly is pulled out by pulling the shifting block 22 , and the communication card 40 therein is replaced.

[0033] In summary, the dual-mode communication module with topology recognition can push the dial block 22 through the arc surface setting of the secondary abutment block 33 and the main abutment block 24 to make the arc surface of the main abutment block 24 contact the arc surface of the secondary abutment block 33, thereby abutting the secondary abutment block 33 to drive the corresponding contact pin 32 to rotate to the side away from the card tray 20. At this time, the connection between the contact pin 32 and the communication card 40 can be disconnected, thereby achieving the effect of direct mechanical card removal, and can respond quickly in more urgent situations. When the emergency situation is resolved, the dial block 22 can be dialed again to reset it, and the protected communication card 40 can be connected again, so that it can work directly and quickly; the protection slide plate 25 can be kept stationary in a fixed position through the limit between the groove and the positioning protrusion 27, thereby avoiding its reset phenomenon, and the current position of the protection slide plate 25 can be judged through the damping feeling between the positioning protrusion 27 and the groove.
