Description

Technical Field

[0001] This invention relates to the field of electronic control cascade devices, and in particular to an electronic control cascade device for rail-mounted instruments. Background Technology

[0002] Currently, the automatic connection and disconnection cascading methods for rail-mounted instruments are mainly divided into two types: One type is the side-to-side insertion of the pins, which requires alignment during installation. This is not very convenient, and the pins will protrude beyond the original product dimensions. Packaging, transportation, and on-site installation can easily cause the pins to become crooked.

[0003] Another type is the post-installation cascade accessory, which is generally a very small accessory. It needs to be aligned during installation, and when it needs to be disconnected in the field, it needs to be pried out with a tool, which makes it easy to be damaged or lost.

[0004] Utility model patent CN203633010U discloses a locking structure for cascaded modules. The locking structure includes a sliding hook, a locking block, and guide rails. The guide rails are respectively disposed on the housing surfaces of two adjacent modules, with recesses B and C at their respective ends. The sliding hook is designed as a semi-enclosed shape and is snapped onto the housing. This patent directly connects the module housings, making the connection between cascaded modules firm and reliable, and ensuring that the performance of the circuit board is not affected. It is used for locking multiple modules used side-by-side; however, both locking and unlocking processes require manual operation, resulting in a low degree of automation.

[0005] Therefore, improving the automation of the locking or unlocking process is an urgent problem to be solved. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electronic control cascade device for rail-mounted instruments.

[0007] The objective of this invention can be achieved through the following technical solutions: According to one aspect of the present invention, an electronically controlled cascade device for a rail-mounted instrument is provided for connecting adjacent onboard components, comprising a control unit, an onboard telescopic unit, a connecting rod, and a cascade component with a double row of pins. The onboard telescopic unit is disposed on the onboard component, the connecting rod is disposed in the onboard telescopic unit and connected to the onboard telescopic unit and the cascade component respectively, the double row of pins is inserted into the onboard component, and the control unit is communicatively connected to the onboard telescopic unit. The control unit controls the start and stop of the onboard telescopic unit to complete the fixing and disassembly of the cascaded components.

[0008] As a preferred technical solution, the onboard telescopic unit includes an excitation winding, a return spring, and an armature. The armature is mounted on a connecting rod, and the return spring is connected to both the excitation winding and the armature. The excitation winding is communicatively connected to the control unit.

[0009] As a preferred technical solution, the excitation winding, reset spring, armature and connecting rod are all coaxial.

[0010] As a preferred technical solution, the connecting rod is made of stainless steel.

[0011] As a preferred technical solution, the connecting rods are located on both sides of the cascade.

[0012] As a preferred technical solution, the cascaded component includes a top shell and a bottom shell, the bottom shell is installed in the fixed shell, the double row of pins is located between the top shell and the bottom shell and passes through the bottom shell, and the connecting rod is connected to the top shell.

[0013] As a preferred technical solution, the double-row pins include a connecting base plate and two pins. The two pins are vertically arranged on the connecting base plate and extend out of the bottom shell. The connecting base plate is respectively in contact with and fixed to the shell and the bottom shell.

[0014] As a preferred technical solution, the onboard unit includes sockets, and adjacent sockets located on different onboard units are connected by a double row of pins.

[0015] As a preferred technical solution, the sockets on different boards are located on the same straight line.

[0016] As a preferred technical solution, the plate also includes a through hole, and the connecting rod is installed in the through hole.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a control unit to drive an onboard telescopic unit in conjunction with a connecting rod to move a cascaded component with double rows of pins, thereby realizing the electrical connection and disconnection of adjacent onboard components. It eliminates the need for manual plugging and unplugging of wiring and mechanical locking, and can complete the electrical connection and mechanical cascade fixation of multiple onboard components. The installation and disassembly are efficient and convenient, and the overall system realizes the automation, standardization and convenient assembly and maintenance of cascaded rail-mounted instrument panels.

[0018] 2. The present invention uses a stainless steel connecting rod, which is non-magnetic and non-magnetic. The connecting rod only transmits the action, does not conduct magnetism, and does not interfere with the magnetic field. The magnetic field basically only travels between the armatures and will not be diverted by the connecting rod or attracted by the electromagnet, ensuring clean action, smooth reset, rust prevention, wear resistance, high strength, and is not easy to rust or deform during long-term operation.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] Example 1 like Figure 1 , Figure 2 and Figure 3 As shown, an electronically controlled cascade device for a rail-mounted instrument is used to connect adjacent onboard components 6. It includes a control unit, an onboard telescopic unit 1, a connecting rod 2, and a cascade component 3 with double-row pins 4. The onboard telescopic unit 1 is mounted on the onboard component 6. The connecting rod 2 is mounted in the onboard telescopic unit 1 and is connected to both the onboard telescopic unit 1 and the cascade component 3. The double-row pins 4 are inserted into the onboard component 6. The control unit is communicatively connected to the onboard telescopic unit 1. The control unit controls the start and stop of the onboard telescopic unit 1 to complete the fixing and disassembly of the cascaded component 3.

[0022] In this embodiment, the rail-mounted instrument can be composed of multiple onboard units 6, each performing a corresponding function. During assembly and use, it is necessary to ensure the secure and reliable connection of each onboard unit, while also enabling communication between the onboard units 6. This device facilitates the connection between different onboard units 6, achieving an automatic connection and disconnection cascade mode. The control unit controls the start and stop of the onboard telescopic unit 1 and unlocks or locks the cascaded unit 3. A remote terminal can be set up, connecting the remote terminal and the control unit wirelessly or via a wired connection, for example, using a Bluetooth module for wireless connection or an RS485 bus for wired connection. The start and stop of the cascaded unit can be controlled by operating the remote terminal.

[0023] When locked, the onboard telescopic unit 1 moves the connecting rod 2 to retract, and the cascade 3, guided by the connecting rod 2, allows the double-row pins 4 to be inserted into two adjacent onboard components 6 to achieve fixation; when unlocked, the onboard telescopic unit 1 pushes out the connecting rod 2, thereby releasing the limit and pushing the cascade 3 to complete the unlocking.

[0024] like Figure 3 and Figure 4 As shown, the onboard telescopic unit 1 includes an excitation winding 11, a return spring 12, and an armature 13. The armature 13 is mounted on the connecting rod 2. The return spring 12 is connected to the excitation winding 11 and the armature 13 respectively. The excitation winding 11 is communicatively connected to the control unit.

[0025] The excitation winding 11, the reset spring 12, the armature 13, and the connecting rod 2 are all coaxial.

[0026] The cascade 3 includes a top shell 31 and a bottom shell 32. The bottom shell 32 is installed in the fixed shell 31. The double row of pins 4 is located between the top shell 31 and the bottom shell 32 and passes through the bottom shell 32. The connecting rod 2 is connected to the top shell 31.

[0027] The double-row pin 4 includes a connecting base plate and two pins. The two pins are vertically arranged on the connecting base plate and extend out of the bottom shell 32. The connecting base plate is in contact with and fixed to the shell 31 and the bottom shell 32 respectively.

[0028] The onboard 6 includes a socket 5, and adjacent sockets 5 located on different onboard 6 are connected by a double row of pins 4.

[0029] The sockets 5 on different onboard boards 6 are located on the same straight line.

[0030] The plate-mounted 6 also includes a through hole, in which the connecting rod 2 is installed.

[0031] In this embodiment, the onboard telescopic unit 1 is specifically an electromagnet, including an excitation winding 11, a return spring 12, and an armature 13. The two ends of the return spring 12 are in contact with the excitation winding 11 and the armature 13, respectively. The armature 13 is fixedly connected to one end of the connecting rod 2, and the size of the armature 13 is larger than the diameter of the return spring 12. Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when the excitation winding 11 is energized, it generates a magnetic field, which attracts the armature 13, causing the armature 13 and connecting rod 2 to move towards the excitation winding 11 and compress the return spring 12. If the excitation winding 11 remains energized, it maintains a strong attraction. The other end of the connecting rod 2 is mounted on the cascade 3, thus locking the cascade 3. The double-row pins 4 are inserted into the socket 5, maintaining the connection for power supply and communication. When disconnection is required, the excitation winding 11 is de-energized, and the force of the return spring 12 pushes out the armature 13 and connecting rod 2, ultimately causing the cascade 3 to pop out and separating the double-row pins 4 from the socket 5, achieving the disconnected state.

[0032] At least one insertion hole 5 is provided on the onboard 6, and preferably two insertion holes 5, to facilitate sequential connection of multiple onboard 6s through this device, with the insertion holes 5 kept on the same straight line. Correspondingly, a through hole is provided on the onboard 6 to facilitate the movement of the connecting rod 2 along the through hole. There are two ways to connect the connecting rod 2 and the cascade 3: one is to make the diameter of the through hole larger than the diameter of the armature 13 and the connecting rod 2, and fix the connecting rod 2 on the cascade 3; the other is to keep the connecting rod 2 in the through hole, and connect and fix the connecting rod 2 to the cascade 3 by a snap or thread, so that the connecting rod 2 can drive the cascade 3. The excitation winding 11, the return spring 12, the armature 13 and the connecting rod 2 are all coaxial to ensure smooth movement.

[0033] The cascade component 3 is divided into a top shell 31 and a bottom shell 32, which are connected as a single unit. A double-row pin 4 is installed between the top shell 31 and the bottom shell 32. The double-row pin 4 includes two pins and a connecting base plate. The two pins extend out of the bottom shell 32 and are inserted into the sockets 5. The two pins are vertically mounted on the connecting base plate, which is fixed by the top shell 31 and the bottom shell 32. A support portion is provided on the bottom shell 32 to support the pins, through which the pins pass. The double-row pin 4 is inserted into the sockets 5 on adjacent onboard components 6 located on different boards, thus connecting two adjacent onboard components 6.

[0034] The connecting rod 2 is made of stainless steel. The connecting rod 2 is located on both sides of the cascade 3.

[0035] In this embodiment, the connecting rod 2 is made of stainless steel, such as 304 stainless steel, which is non-magnetic and non-magnetic. The connecting rod only transmits the action, does not conduct magnetism, and does not interfere with the magnetic field. The magnetic field basically only travels between the armatures and will not be diverted by the connecting rod or attracted by the electromagnet, ensuring clean action, smooth reset, rust prevention, wear resistance, high strength, and that it is not easy to rust or deform during long-term operation.

[0036] Connecting rod 2 is installed on top shell 31. At least two connecting rods 2 are installed and symmetrically arranged on the side of top shell 31. One connecting rod 2 is used for one onboard telescopic unit 1.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
