Description

Technical Field

[0001] The present invention relates to the field of communication interfaces, and in particular to an ultra-low-latency wired communication interface structure for the Internet of Things. Background Art

[0002] Ultra-low latency wired communication of the Internet of Things refers to communication technology that achieves data transmission latency lower than that of traditional wired communication methods through efficient channel coding and modulation technology, high-speed switching technology and optimized network protocols. At present, the wired communication of the Internet of Things includes Ethernet, RS-232, RS-485, CAN bus and other communication methods. Among them, when RS-232, RS-485 and CAN bus are connected to wired communication devices, the end plug of the data communication transmission line is usually docked at the communication interface position of the device, and then the two sets of bolts of the plug are screwed into the threaded holes on both sides of the communication interface of the device to lock the plug at the end of the transmission line with the communication interface.

[0003] However, the traditional wired communication interface uses two sets of bolts to connect two sets of threaded holes for screwing and fixing, which is rather cumbersome. The disassembly and assembly of the data cable at the communication interface requires screwing two sets of bolts to complete, and the plugging and unplugging operation of the data transmission cable connector is inefficient. In addition, the structure between the data transmission cable connector and the device communication interface is relatively exposed, and the plug-in part does not have a shielding protection structure, so external pollutants can easily invade the connection part of the communication interface. Summary of the Invention

[0004] The purpose of the present invention is to provide an ultra-low latency wired communication interface structure for the Internet of Things to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the inventors provide an ultra-low latency wired communication interface structure for the Internet of Things, comprising:

[0006] The interface mounting panel is provided with a through hole on the front side of the interface mounting panel, and a fixing bolt is inserted into the through hole of the interface mounting panel, and the outer side of the fixing bolt is engaged with the fixing nut; it also includes a data line connector device and a communication interface device; the data line connector device includes a sheath, a locking seat, a locking rod, a plug connector, a connector housing, a ring plate, a knob, a guide rod and a push spring; the outer side of the plug connector is bonded with a locking seat, the outer side of the locking seat is bonded with the connector housing, and the outer side of the connector housing is welded with a ring plate; the outer side of the locking rod is rotatably connected to the connector housing, the outer side of the connector housing is slidably connected to the sheath, the rear end of the sheath is welded with a push spring, and the front side of the locking rod is installed with a knob; the front and rear ends of the guide rod are welded to the connector housing; the communication interface device includes a plug connector, a button, an interface housing, a lock plate, a return spring and a support rod; the lock plate is bonded to the button, and the lock plate is welded to the return spring; the outer side of the plug connector is bonded to the interface housing, the inner side of the interface housing is welded with a support rod, and the outer side of the support rod is slidably connected to the lock plate.

[0007] Furthermore, there are two groups of lock tongue plates, which are symmetrically distributed on the left and right. The lock tongue plates are L-shaped structures, and the front side surfaces of the lock tongue plates are inclined structures. The upper side surfaces and the lower side surfaces of each group of lock tongue plates are provided with convex plates, and each group of convex plates of the lock tongue plates is provided with two groups of through-hole structures that pass through the left and right. The support rods are inserted into the through holes of the lock tongue plates, and the support rods support the two groups of lock tongue plates to move in a directional manner left and right.

[0008] Furthermore, convex plates are provided on the left and right sides of the locking seat near the rear end, and each set of the convex plates is provided with a through groove structure that passes through the front and back. When the L-shaped structure of the lock tongue plate is inserted into the through groove structure of the locking seat, the rear end edge of the through groove structure of the locking seat squeezes the inclined structure of the lock tongue plate.

[0009] Furthermore, the sheath is a rectangular cylindrical structure that passes through from front to back, a rubber gasket is bonded to the rear end of the cylindrical structure of the sheath, two groups of protrusions are provided on the inner side surface of the sheath near the front end, the protrusions are symmetrically distributed on the left and right, a through-hole structure that passes through from front to back is provided at the center position of the left protrusion of the sheath, an opening groove that passes through from front to back is provided on the inner side surface of the through-hole of the left protrusion of the sheath, the locking rod is inserted into the through-hole of the left protrusion of the sheath, a through-hole that passes through from front to back is provided at the center position of the right protrusion of the sheath, the guide rod is inserted into the through-hole of the right protrusion of the sheath, and the guide rod and the locking rod support the sheath to slide in a directional manner on the outside of the joint shell.

[0010] Furthermore, a sheath is welded to the rear end of the push spring, and a joint shell is welded to the front end of the push spring. The push spring pushes the sheath to slide backward along the length direction of the sheath through its own elastic force, so that the sheath squeezes the rubber gasket.

[0011] Furthermore, a square protrusion is provided on the outer side of the locking rod, and the square protrusion driven by the locking rod rotates synchronously. The square protrusion of the locking rod is inserted into the opening groove of the protrusion through hole on the left side of the sheath. When the square protrusion driven by the locking rod is relative to the rear side of the opening groove of the sheath protrusion through hole, the locking rod unlocks the forward and backward movement of the sheath, and the sheath moves forward and backward along the locking rod arbitrarily. When the square protrusion driven by the locking rod is staggered with the rear side of the opening groove of the sheath protrusion through hole, the locking rod locks the forward and backward movement of the sheath to prevent the push spring from driving the sheath to pop out automatically.

[0012] Furthermore, there are four groups of return springs, which are nested in the outer side of the support rod. The left and right ends of each group of return springs are welded with lock tongue plates. The return springs push the two groups of lock tongue plates to move apart in opposite directions along the support rod through their own elastic force. When the front end of the L-shaped structure of the locking seat passes through the through slot of the locking seat, the bent part of the L-shaped structure of the lock tongue plate automatically fits into the front edge of the through slot of the locking seat.

[0013] Furthermore, ear plates are provided on the left and right sides of the interface shell near the rear end, and the front side of each group of the ear plates is provided with a circular ear plate through hole, the fixing bolts are inserted into the ear plate through holes of the interface shell, and the ear plate through holes of the interface shell are opposite to the through holes of the interface mounting panel front and back, and the fixing bolts cooperate with the fixing nuts screwed on the outer side to fix the interface shell on the front side of the through holes of the interface mounting panel, and the left and right sides of the interface shell are provided with rectangular through grooves, and buttons are inserted in the rectangular through grooves of the interface shell, and the two groups of buttons are pressed towards each other to synchronously drive the lock tongue plate to move towards the left and right, so that the L-shaped structure bending part of the lock tongue plate quickly disengages from the front edge of the through groove of the locking seat to complete the unlocking work.

[0014] Furthermore, the contact surface between the plug connector and the plug interface is provided with a gold-plated layer, and the thickness of the gold-plated layer is 0.5-1.2 microns.

[0015] Furthermore, an electromagnetic shielding layer is provided inside the interface shell, and the electromagnetic shielding layer is made of copper foil material with a thickness of 0.1-0.3 mm. A conductive rubber sealing ring is provided at the junction of the sheath and the connector shell to form a continuous electromagnetic shielding path.

[0016] Different from the existing technology, the above technical solution has the following advantages: in the present invention, on the one hand, the elastic force of the return spring itself is used to drive the L-shaped lock tongue plate to squeeze and fit into the notch position on the front side of the locking seat slot, so that a nested and interlaced limiting locking structure is formed between the locking seat and the lock tongue plate, which realizes the rapid plug-in and locking of the plug connector and the plug interface; on the other hand, by manually pressing the button, the two groups of lock tongue plates are driven to move toward each other left and right, so that the lock tongue plates are quickly separated from the notch position on the front side of the locking seat slot, thereby realizing the rapid removal and unlocking operation of the plug connector and the plug interface, avoiding the operation process of multiple twisting of two groups of bolts in the threaded holes in the traditional interface, improving the plug-in and unplugging speed of the data cable connector and the equipment communication interface, and the plug-in and unplugging operation is simple and fast.

[0017] In addition, in the present invention, the push spring drives the sheath of the cylindrical structure through its own elastic force to squeeze backward along the guide rod and fit onto the front side of the interface mounting panel, so that the plug-in parts of the plug interface and the plug connector are wrapped inside the cylindrical structure of the sheath, thereby achieving the covering and shielding of the plug interface and the plug connector by the sheath, preventing external dust and splashing water from directly invading the connection part between the data transmission line connector and the equipment communication interface.

[0047] In some embodiments, there are two groups of lock tongue plates 304, and the lock tongue plates 304 are symmetrically distributed on the left and right. The lock tongue plates 304 are L-shaped structures, and the front side surfaces of the lock tongue plates 304 are inclined structures. The upper side surfaces and the lower side surfaces of each group of lock tongue plates 304 are provided with convex plates, and each group of convex plates of the lock tongue plates 304 are provided with two groups of through-hole structures that pass through the left and right. The support rods 306 are inserted into the through-holes of the lock tongue plates 304, and the support rods 306 support the two groups of lock tongue plates 304 for directional movement left and right, ensuring that the inclined protrusions at the front end of the lock tongue plates 304 are stably docked with the through slots of the locking seat 202 for insertion or extraction, and avoiding the lock tongue plates 304 from flipping and tilting left and right, causing the lock tongue plates 304 to be stuck in the through slots of the locking seat 202 when being inserted or extracted.

[0048] In some embodiments, convex plates are provided on the left and right sides of the locking seat 202 near the rear end, and each set of convex plates is provided with a through groove structure that passes through the front and back. When the L-shaped structure of the lock tongue plate 304 is inserted into the through groove structure of the locking seat 202, the rear end edge of the through groove structure of the locking seat 202 squeezes the inclined structure of the lock tongue plate 304, so that the two sets of lock tongue plates 304 move closer to each other left and right along the support rod 306, allowing the lock tongue plate 304 to automatically avoid the through groove wall of the locking seat 202 and penetrate into the through groove of the locking seat 202.

[0049] In some embodiments, the sheath 201 is a rectangular cylindrical structure that is through-through from front to back, and a rubber gasket is bonded to the rear end of the cylindrical structure of the sheath 201. Two groups of protrusions are provided on the inner side surface of the sheath 201 near the front end, and the protrusions are symmetrically distributed on the left and right. A through-hole structure that is through-through from front to back is provided at the center position of the left protrusion of the sheath 201, and an opening groove that is through-through from front to back is provided on the inner side surface of the through-hole of the left protrusion of the sheath 201. The locking rod 203 is inserted into the through-hole of the left protrusion of the sheath 201, and a through-hole that is through-through from front to back is provided at the center position of the right protrusion of the sheath 201. The guide rod 208 is inserted into the through-hole of the right protrusion of the sheath 201, and the guide rod 208 and the locking rod 203 support the sheath 201 to slide directionally on the outside of the connector shell 205, so that the sheath 201 is moved to the plug-in position of the data cable connector device 2 and the communication interface device 3 for shielding, thereby preventing external pollutants from directly invading the communication interface structure.

[0050] like Figure 12 As shown, in some embodiments, the rear end of the push spring 209 is welded with a sleeve 201, and the front end of the push spring 209 is welded with a connector housing 205. The push spring 209 pushes the sleeve 201 to slide backward along the length direction of the sleeve 201 through its own elastic force, so that the sleeve 201 squeezes the rubber gasket, ensuring that the rubber gasket bonded to the rear end of the sleeve 201 fits tightly against the front side of the interface mounting panel 1 for contact sealing.

[0051] In some embodiments, a square protrusion is provided on the outer side of the locking rod 203, and the square protrusion driven by the locking rod 203 rotates synchronously. The square protrusion of the locking rod 203 is inserted into the opening groove of the protrusion hole on the left side of the sheath 201. When the square protrusion driven by the locking rod 203 is relative to the rear side of the opening groove of the protrusion hole of the sheath 201, the locking rod 203 unlocks the forward and backward movement of the sheath 201, and the sheath 201 moves forward and backward arbitrarily along the locking rod 203. When the square protrusion driven by the locking rod 203 is staggered with the rear side of the opening groove of the protrusion hole of the sheath 201, the locking rod 203 locks the forward and backward movement of the sheath 201 to prevent the push spring 209 from driving the sheath 201 to pop out automatically.

[0052] In some embodiments, there are four groups of return springs 305, and the return springs 305 are nested on the outer side of the support rod 306. The left and right ends of each group of return springs 305 are welded with lock tongue plates 304. The return springs 305 push the two groups of lock tongue plates 304 to move apart in opposite directions along the support rod 306 through their own elastic force. When the front end of the L-shaped structure of the locking seat 202 passes through the through slot of the locking seat 202, the bent part of the L-shaped structure of the lock tongue plate 304 automatically fits into the front edge of the through slot of the locking seat 202, and the lock tongue plate 304 moves forward and backward to limit and lock the locking seat 202, thereby realizing the plug-in locking of the data cable connector device 2 and the communication interface device 3.

[0053] In some embodiments, ear plates are provided on the left and right sides of the interface shell 303 near the rear end, and the front side of each group of ear plates is provided with a circular ear plate through hole, and the fixing bolts 5 are inserted into the ear plate through holes of the interface shell 303. The ear plate through holes of the interface shell 303 are opposite to the through holes of the interface mounting panel 1 front and back, and the fixing bolts 5 cooperate with the fixing nuts 4 screwed on the outer side to fix the interface shell 303 on the front side of the through holes of the interface mounting panel 1. The left and right sides of the interface shell 303 are provided with rectangular through grooves, and buttons 302 are inserted in the rectangular through grooves of the interface shell 303. By squeezing and pressing the two groups of buttons 302 in opposite directions, the lock tongue plate 304 is synchronously driven to move toward each other left and right, so that the L-shaped structure bending part of the lock tongue plate 304 quickly disengages from the front edge of the through groove of the locking seat 202 to complete the unlocking work, and the unlocking operation is simple and fast.

[0054] In some embodiments, the contact surface between the plug connector and the plug interface is provided with a gold-plated layer, and the thickness of the gold-plated layer is 0.5-1.2 microns.

[0055] In some embodiments, an electromagnetic shielding layer is provided inside the interface shell. The electromagnetic shielding layer is made of copper foil material with a thickness of 0.1-0.3 mm. A conductive rubber sealing ring is provided at the joint between the sheath and the connector shell to form a continuous electromagnetic shielding path.

[0056] The specific usage and function of this embodiment are as follows:

[0057] When the data line connector device 2 and the communication interface device 3 are plugged and locked, the plug connector 204 is docked at the front side of the plug interface 301 and inserted. At this time, the rear edge of the through slot of the locking seat 202 is fitted with the inclined structure of the front side of the lock tongue plate 304. The edge of the notch on the rear side of the two groups of through slots of the locking seat 202 synchronously squeezes the lock tongue plate 304. The lock tongue plate 304 moves toward each other along the support rod 306. The lock tongue plate 304 goes deep into the through slot of the lock tongue plate 304. When the L-shaped bent part of the lock tongue plate 304 passes through the through slot of the lock tongue plate 304, the return spring 305 is elastically pressed When the locking cam 201 is unlocked, the locking cam 202 is unlocked, and the locking cam 202 is unlocked, so that the locking cam 202 can be unlocked. 209 drives the sheath 201 to move backward along the guide rod 208 until the rubber gasket bonded to the rear end of the sheath 201 fits against the front side of the interface installation panel 1. The sheath 201 covers and shields the plug connector 204 and the plug interface 301. When unlocking and unplugging the data cable connector device 2 and the communication interface device 3, the sheath 201 is manually pulled forward, and the square protrusion of the locking rod 203 passes through the through-hole groove of the protrusion on the left side of the sheath 201 and penetrates into the inner side of the sheath 201. Then, the knob 207 is turned, and the knob 207 drives the square protrusion on the outer side of the locking rod 203 to rotate. When the square protrusion of the locking rod 203 and the sheath are unlocked, the locking rod 203 and the sheath are unlocked. When the through-hole grooves of the left protrusion on the inner side of 201 are staggered, the locking rod 203 moves forward and backward to lock the sheath 201, and then the two sets of buttons 302 are manually pressed, and the two sets of buttons 302 respectively push the two sets of locking tongue plates 304 to move left and right towards each other. At this time, the L-shaped bending part of the locking tongue plate 304 is separated from the edge of the notch on the front side of the through slot of the locking seat 202, and then the other hand pinches the connector shell 205 and moves forward, the plug connector 204 is separated from the plug interface 301 forward, and the L-shaped bending part of the locking tongue plate 304 is separated from the through slot of the locking seat 202, thereby completing the unlocking and unplugging of the data cable connector device 2 and the communication interface device 3.

[0058] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.

Two groups of protrusions are provided on the inner side surface of the sheath near the front end, and the protrusions are symmetrically distributed on the left and right. A through-hole structure that passes through from front to back is provided at the center position of the left protrusion of the sheath, and an opening groove that passes through from front to back is provided on the inner side surface of the through-hole of the left protrusion of the sheath. The locking rod is inserted into the through-hole of the left protrusion of the sheath, and a through-hole that passes through from front to back is provided at the center position of the right protrusion of the sheath. The guide rod is inserted into the through-hole of the right protrusion of the sheath, and the guide rod and the locking rod support the sheath to slide directionally on the outside of the joint shell.

5. The ultra-low latency wired communication interface structure according to claim 1, wherein: A sheath is welded to the rear end of the push spring, and a joint shell is welded to the front end of the push spring. The push spring pushes the sheath to slide backward along the length direction of the sheath through its own elastic force, so that the sheath squeezes the rubber gasket.

6. The ultra-low latency wired communication interface structure according to claim 1, wherein: The outer side surface of the locking rod is provided with a square protrusion, and the square protrusion driven by the locking rod rotates synchronously. The square protrusion of the locking rod is inserted into the opening groove of the protrusion through hole on the left side of the sheath. When the square protrusion driven by the locking rod is relative to the rear side of the opening groove of the sheath protrusion through hole, the locking rod unlocks the forward and backward movement of the sheath, and the sheath moves forward and backward along the locking rod arbitrarily. When the square protrusion driven by the locking rod is staggered with the rear side of the opening groove of the sheath protrusion through hole, the locking rod locks the forward and backward movement of the sheath to prevent the push spring from driving the sheath to pop out automatically.

7. The ultra-low latency wired communication interface structure according to claim 1, wherein: There are four groups of return springs, which are nested in the outer side of the support rod. A lock tongue plate is welded to the left and right ends of each group of return springs. The return springs push the two groups of lock tongue plates to move apart in opposite directions along the support rod through their own elastic force. When the front end of the L-shaped structure of the locking seat passes through the through slot of the locking seat, the bent part of the L-shaped structure of the lock tongue plate automatically fits into the front edge of the through slot of the locking seat.

8. The ultra-low latency wired communication interface structure according to claim 1, wherein: The left and right sides of the interface shell are provided with ear plates near the rear end, and the front side of each group of the ear plates is provided with a circular ear plate through hole, the fixing bolts are inserted into the ear plate through holes of the interface shell, and the ear plate through holes of the interface shell are opposite to the through holes of the interface mounting panel front and back, and the fixing bolts cooperate with the fixing nuts screwed on the outer sides to fix the interface shell on the front side of the through holes of the interface mounting panel, and the left and right sides of the interface shell are provided with rectangular through grooves, and buttons are inserted in the rectangular through grooves of the interface shell, and the two groups of buttons are pressed towards each other to synchronously drive the lock tongue plate to move towards the left and right, so that the L-shaped structure bending part of the lock tongue plate quickly disengages from the front edge of the through groove of the locking seat to complete the unlocking work.
