Technical Field

[0001] This utility model relates to the field of communication interface technology, and in particular to a protective structure for RS485 communication interfaces. Background Technology

[0002] The RS-485 communication interface is a standard belonging to the physical layer of the OSI model, specifying electrical characteristics for 2-wire, half-duplex, balanced transmission lines for multipoint communication. It was jointly published by the Telecommunications Industry Association (TIA) and the Electronic Industries Alliance (EIA). Digital communication networks implementing this standard can achieve efficient long-distance communication in environments with electronic noise. In a linear multipoint bus configuration, multiple receivers can be located on a single network, making it suitable for industrial environments.

[0003] RS485 communication interfaces come in male and female connectors, with the male connector typically plugged into the female connector for connection. However, neither the male nor female connectors of the RS485 communication interface have external protection, and after plugging them in, some metal is exposed, making them susceptible to water ingress and potential short circuits.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a protective structure for RS485 communication interfaces. Utility Model Content

[0005] The purpose of this invention is to provide a protective structure for RS485 communication interfaces in order to solve the above-mentioned problems.

[0010] Furthermore, the auxiliary docking structure includes a docking rod vertically disposed on the male end face and a docking post vertically disposed on the female end face, wherein the docking post has a socket for inserting the docking rod.

[0011] Furthermore, the sum of the lengths of the mating rod and the mating post is greater than the sum of the lengths of the insertion ends of the male and female heads.

[0012] Furthermore, the sealed protective structure includes an annular plug disposed on the male end face and an annular socket disposed on the female end face, wherein a slot for inserting the annular plug is provided on the end face of the annular socket.

[0013] Furthermore, the inner side of the slot of the ring socket has ring-shaped elastic protrusions on both opposite sides near the edge.

[0014] Furthermore, the annular elastic protrusion has a sloping surface from the outside of the slot to the inside, so that the insertion diameter of the slot gradually decreases from the outside to the inside.

[0015] Furthermore, the annular elastic protrusion is a rubber protrusion.

[0016] In the above technical solution, the protective structure for RS485 communication interface provided by this utility model has the following beneficial effects:

[0017] During the mating process of the male and female connectors of the RS485 communication interface, this device uses an auxiliary mating structure to assist in the mating, making the insertion of the male and female connectors more precise.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 A protective structure for an RS485 communication interface includes a male connector 1 and a female connector 2 of the RS485 communication interface, wherein the male connector 1 and the female connector 2 are plugged into each other and fixedly connected by bolts, and further includes:

[0027] An auxiliary docking structure is installed between male connector 1 and female connector 2. This structure allows for pre-docking before the actual connection between male connector 1 and female connector 2. Since the connectors between male connector 1 and female connector 2 require initial docking before insertion, and a final bolt connection is also needed, inaccurate docking would complicate subsequent bolt tightening. Therefore, by first achieving docking through the auxiliary structure, direct force can be applied for insertion, enabling quick and accurate connection between male connector 1 and female connector 2, aligning the bolt holes, and facilitating installation.

[0028] A sealed protective structure is installed between the male connector 1 and the female connector 2 to form a sealed enclosure between the male connector 1 and the female connector 2 when they are connected, so as to provide dustproof and waterproof protection for the connection part.

[0029] Furthermore, the auxiliary docking structure includes a docking rod 3 vertically set on the end face of the male head 1 and a docking post 4 vertically set on the end face of the female head 2. The docking post 4 has a socket 5 for inserting the docking rod 3. During docking, the docking rod 3 is first inserted into the socket 5 of the docking post 4 for positioning, which also aligns the insertion parts of the male head 1 and the female head 2 and the bolts.

[0030] Furthermore, the sum of the lengths of the mating rod 3 and the mating post 4 is greater than the sum of the lengths of the insertion ends of the male head 1 and the female head 2, so that when the male head 1 and the female head 2 are mated, the mating rod 3 and the mating post 4 will be the first to contact and mate, thus enabling alignment before insertion and connection.

[0031] Furthermore, the sealed protective structure includes an annular plug 6 disposed on the end face of the male connector 1 and an annular socket 7 disposed on the end face of the female connector 2. A slot 8 is provided on the end face of the annular socket 7 for inserting the annular plug 6. The annular plug 6 is inserted into the slot 8 of the annular socket 7 to achieve a seal. Furthermore, the annular plug 6 is pressed against the bottom surface of the slot 8 to achieve a seal.

[0032] Furthermore, on the opposite sides of the inner side of the slot 8 of the ring socket 7 near the edge, there are ring-shaped elastic protrusions 9. The ring-shaped elastic protrusions 9 are equivalent to completely and tightly fitting the side of the ring plug 6 inserted into the slot 8, so that the sealed protective structure can achieve further sealing.

[0033] Furthermore, the annular elastic protrusion 9 has a sloping surface from the outside to the inside of the slot 8, so that the insertion diameter of the slot 8 gradually decreases from the outside to the inside, making it easier to insert the annular plug 6. The gradual decrease in the insertion diameter from the outside to the inside also has the effect of wrapping tightly around the annular plug 6, further enhancing the sealing effect.

[0034] Furthermore, the annular elastic protrusion 9 is made of rubber, which makes it elastic and can enhance the sealing effect through compression under elastic deformation, so as to provide more rigorous sealing protection for the RS485 communication interface connection part.

[0035] In summary, this device uses an auxiliary connection structure to assist in the connection of the male and female connectors of the RS485 communication interface, making the insertion of the male and female connectors more precise. At the same time, the sealed protective structure provides sealing protection for the insertion parts of the male and female connectors, thus protecting the RS485 communication interface and providing dustproof and splashproof functions.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
