Description

Technical Field

[0001] The utility model relates to the technical field of converters, in particular to a multi-communication protocol converter. Background Art

[0002] Protocol converter is abbreviated as protocol converter, also called interface converter. It enables hosts using different high-level protocols on the communication network to cooperate with each other and complete various distributed applications. It works at the transport layer or higher. The interface protocol converter can generally be completed with an ASIC chip, which is low-cost and small in size. It can convert between the Ethernet or V.35 data interface of the IEEE802.3 protocol and the 2M interface of the standard G.703 protocol, and can also convert between 232 / 485 / 422 serial ports and E1, CAN interfaces and 2M interfaces.

[0003] When using a data cable to connect to an interface on a protocol converter, the connector of the data cable is usually directly slid and plugged into the connector on the protocol converter, so that the data cable is collided and pulled, which will cause the data cable to separate from the protocol converter. In order to ensure the stability of the data cable installation, two connecting bolts are slid and inserted on both sides of the data cable connector. However, when using bolts to connect, the efficiency of its disassembly and installation will be reduced, thereby reducing its practical performance.

[0004] Therefore, it is necessary to design a multi-communication protocol converter with strong practicality and more stable connector when plugged in. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-communication protocol converter to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-communication protocol converter, comprising a protocol converter body, a connector for connecting an external device is plugged into the protocol converter body, a connecting block is fixedly connected to the outer wall of the protocol converter body, a jack is penetrated through the side wall of the connecting block, the connecting head is slidably connected in the jack, an upper baffle and a lower baffle are hingedly connected to the side wall of the connecting block, a fixed block is fixedly connected to the side wall of the lower baffle, a curved head is provided on the end face of the fixed block, an active cavity is provided on the side wall of the connecting block, the fixed block is movably connected to the active cavity, a positioning rod is slidably connected to the lower end face of the connecting block, a positioning hole is penetrated through the surface of the fixed block, the upper end of the positioning rod is slidably connected to the positioning hole, and the upper end of the positioning rod is provided with an inclined surface, the lower end face of the positioning rod is fixedly connected to an end head, a reset spring is fixedly connected between the end head and the surface of the connecting block, and the reset spring is sleeved on the outer side of the positioning rod, and the side walls of the upper baffle and the lower baffle are penetrated with a threading hole for accommodating a data line at the tail of the connector.

[0007] According to the above technical solution, the side wall of the insertion hole is provided with an expansion slope.

[0008] According to the above technical solution, the side walls of the upper baffle plate and the lower baffle plate are symmetrically fixedly connected with dustproof pads.

[0009] According to the above technical solution, the side walls of the upper baffle plate and the lower baffle plate are staggered and provided with splicing parts.

[0010] According to the above technical solution, a protruding block is fixedly connected to the side wall of the upper baffle.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model is provided with a protocol converter body, and a plug interface for plugging a connector is provided on the protocol converter body. When a staff member plugs the connector into the protocol converter body through the plug interface, the external device can be connected to the protocol converter body. The connection block is arranged on the outside of the connector. When the connector passes through the jack and is plugged into the protocol converter body, the connection block can protect the connector. The upper baffle and the lower baffle are respectively arranged at the upper and lower ends of the same side of the connector. The position of the active cavity corresponds to the fixed block. When the staff member flips the lower baffle upwards, the fixed block will enter the active cavity. The positioning rod can slide vertically in the connection block. When the fixed block enters the active cavity, the positioning rod will be inserted into the fixed cavity. The positioning hole completes the positioning of the fixed block, so that the position of the lower baffle is fixed. When the fixed block enters the active cavity, the inclined surface will contact the curved head, and the curved head will squeeze the inclined surface and move the positioning rod downward. At this time, the reset spring is stretched. When the reset spring shrinks and resets, the positioning rod is reset upward through the end head and inserted into the positioning hole. The threading hole is a semicircular through hole, which is arranged on the side walls opposite to the upper baffle and the lower baffle. By inserting the connector into the jack, the connecting block protects the connector. The connector is limited by flipping the upper baffle and the lower baffle to prevent the connector from being unstable in connection, which is easy to separate from the protocol converter body. The fixed block is positioned in the active cavity by the positioning rod, so that the lower baffle is fixed. The curved head and the inclined surface make the device more convenient to use.

[0012] The expansion bevel used can make one end of the jack wider, making it easier for workers to plug in the connector.

[0013] The dustproof pad is arranged between the upper baffle, the lower baffle and the connecting block, which can play a dustproof role and prevent dust from entering the connecting block through the jack when the upper baffle and the lower baffle are buckled, thereby affecting the connection between the connector and the protocol converter body.

[0014] The splicing part is arranged on the two side walls adjacent to the upper baffle and the lower baffle. When the upper baffle and the lower baffle are buckled, the two splicing parts are spliced ​​together. The upper baffle can be limited by the lower baffle, and the contact area between the upper baffle and the lower baffle can be increased to achieve better dustproof effect.

[0015] The protruding block is arranged on one side of the upper baffle plate. When the positioning rod slides out of the positioning hole and the limit on the fixed block is cancelled, the staff can flip the upper baffle plate and the lower baffle plate through the protruding block.
