Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically a split-type terminal block structure. Background Technology

[0002] Terminal blocks are components used to achieve reliable connections between wires and cables and electrical equipment. They play a crucial role in electrical systems, not only ensuring reliable connections between wires and between wires and electrical equipment, but also guaranteeing stable transmission of current or signals, providing electrical isolation and protection, facilitating maintenance and replacement, adapting to different environmental conditions, improving system flexibility, and complying with various standards and specifications. These functions make terminal blocks an indispensable component of electrical systems.

[0003] Terminal blocks typically consist of multiple metal plates arranged parallel to each other and spaced apart. In high-frequency signal transmission, parasitic capacitance forms between these plates. As the signal frequency increases, the capacitive reactance decreases sharply, and the capacitor exhibits "low impedance" characteristics, significantly impacting signal transmission and causing signal delay, phase shift, and signal attenuation. Utility Model Content

[0004] The purpose of this invention is to provide a split terminal block structure to solve the problem mentioned in the background art where the mechanism arm and signal arm of the multiple metal plates of the terminal block are integrated into one unit. Therefore, when the signal frequency increases, the capacitive reactance of the capacitor decreases sharply, which easily leads to a capacitive effect and affects the transmission of high-frequency signals.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split-type terminal block structure, including a main body, an auxiliary component for reducing terminal capacitance effect is provided on the outside of the main body, the auxiliary component includes a cover plate provided on the top of the main body, a plurality of mounting grooves are provided on the inner wall of the main body, and terminal strips are provided inside the plurality of mounting grooves, one end of the terminal strips is provided with a mechanism end and a signal end;

[0006] The main body has guide grooves at both ends of its inner wall, and fixing plates are provided on the inner walls of both guide grooves. A shielding shell is provided on the top of the main body. A plug is provided at the bottom of both ends of the shielding shell. A locking hole is provided at both ends of the shielding shell. A positioning hole is provided at both ends of the top of the main body. Buckles are provided on both sides of the main body.

[0007] Preferably, the cover plate is located inside the main body, and one end is rotatably connected to the inner wall of the main body. Multiple mounting slots are distributed on the inner wall of the main body, and multiple terminal strips are inserted into the mounting slots.

[0008] Preferably, one end of the mechanism end and one end of the signal end are both on one side of the terminal strip and are arranged in an array on one side of the terminal strip, and the other end of the mechanism end and the signal end are inserted into the mounting groove.

[0009] Preferably, the guide grooves are distributed at both ends of the inner wall of the main body, and one end of the fixing piece can be inserted into the guide groove and slidably connected to the inner wall of the guide groove.

[0010] Preferably, the shielding shell is located on the top of the main body, one end of the plug is connected to both ends of the bottom of the shielding shell, and the other end is inserted into the positioning hole on the top of the main body.

[0011] Preferably, the card hole penetrates through the outer wall of the shielding shell, the buckle is at an inclined angle and corresponds to the card hole on the outer wall of the shielding shell, and the card hole on the outer wall of the shielding shell is connected to the buckle sleeve when the shielding shell is installed with the main body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By designing the terminals as separate structures, the mechanical end and the signal end are disconnected, forming two terminals. This reduces the capacitive effect of integrated terminals and improves high frequency and high speed. At the same time, the double-layer stepped structure of the terminals can realize conversion (converting a single input signal to other devices or extending it to other devices) or splitting (single signal input, splitting into two signal outputs), improving the stability of signal transmission.

[0014] 2. Furthermore, a shielding shell is installed on the top of the main body. The shielding shell can shield the noise on the internal and external FFC and guide the current to the PCB ground, so that the signal terminals are not interfered with, which is conducive to high frequency improvement.

[0015] This invention uses a separate, double-layered stepped structure for the terminals, forming two independent terminals. This reduces capacitance effects and improves the quality of high-frequency signal transmission. Furthermore, by adding a shielding shell, the signal terminals are protected from interference, which is beneficial for high-frequency enhancement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0023] Please see Figures 1-3 A split-type terminal block structure includes a main body 1. An auxiliary component for reducing terminal capacitance effect is provided on the outside of the main body 1. The auxiliary component includes a cover plate 2 on the top of the main body 1. The cover plate 2 provides electrical insulation and physical protection for the terminal block. Multiple mounting grooves 3 are provided on the inner wall of the main body 1 to position the terminal block. Terminal strips 4 are provided inside the multiple mounting grooves 3, which can arrange the mechanism end 401 and signal end 402 in a strip-like continuous manner. The mechanism end 401 and signal end 402 are provided at one end of the terminal strip 4. The mechanism end 401 and signal end 402 are separate.

[0024] The cover plate 2 is located inside the main body 1, and one end is rotatably connected to the inner wall of the main body 1. Multiple mounting slots 3 are arrayed on the inner wall of the main body 1. Multiple terminal strips 4 are inserted into the mounting slots 3. One end of the mechanism end 401 and the signal end 402 are both on one side of the terminal strip 4 and are arranged in an array on one side of the terminal strip 4. The other end of the mechanism end 401 and the signal end 402 are inserted into the mounting slot 3.

[0025] Specifically: In use, first connect the cover plate 2 to the main body 1, and then use the terminal strip 4 to insert the mechanism end 401 and the signal end 402 into the mounting groove 3 of the main body 1 to install the terminal. The mechanism end 401 and the signal end 402 at one end of the terminal strip 4 can form a double-layer stepped structure, thereby disconnecting the two terminals to form two separate terminals, reducing the capacitance effect of the integrated terminal, and improving high frequency and high speed. At the same time, the double-layer stepped structure can realize conversion (that is, converting a single input signal to other devices or extending it to other devices) or splitting (that is, a single signal input is split into two signal outputs).

[0026] Please see Figures 2-4 The main body 1 has guide grooves 5 at both ends of its inner wall to position the fixing piece 6. The inner walls of the two guide grooves 5 are equipped with fixing pieces 6. The main body 1 has a shielding shell 7 at the top. The shielding shell 7 can be installed on the top of the main body 1. The bottom of both ends of the shielding shell 7 is equipped with plugs 701. The plugs 701 can be inserted into the positioning holes 8 when the shielding shell 7 is installed with the main body 1 to position the angle of the shielding shell 7. The shielding shell 7 has locking holes 702 at both ends. The main body 1 has positioning holes 8 at both ends of its top to guide the position of the shielding shell 7 installed with the main body 1. The main body 1 has buckles 9 on both sides. The buckles 9 can be inserted into the locking holes 702 at both ends of the shielding shell 7 when the shielding shell 7 is fitted on the top of the main body 1 to fix the shielding shell 7.

[0027] The guide grooves 5 are distributed at both ends of the inner wall of the main body 1. One end of the fixing piece 6 can be inserted into the guide groove 5 and slidably connected to the inner wall of the guide groove 5. The shielding shell 7 is located at the top of the main body 1. One end of the plug 701 is connected to both ends of the bottom of the shielding shell 7, and the other end is inserted into the positioning hole 8 at the top of the main body 1. The locking hole 702 penetrates the outer wall of the shielding shell 7. The buckle 9 is at an inclined angle and corresponds to the locking hole 702 on the outer wall of the shielding shell 7. When the shielding shell 7 is installed with the main body 1, the locking hole 702 on the outer wall is connected to the buckle 9.

[0028] Specifically: After the terminals are installed, the fixing piece 6 is inserted and fixed into the main body 1 according to the guide groove 5. Then, the terminal material tape 4 is removed, and the shielding shell 7 is connected to the top of the main body 1 according to the bottom plug 701 and the positioning hole 8 on the top of the main body 1. At the same time, the locking holes 702 at both ends of the shielding shell 7 are fixed on the buckles 9 on both sides of the main body 1. The shielding shell 7 acts to shield the noise inside and outside and on the FFC, and guides the current to the PCB ground, so that the signal terminals are not interfered with, which is conducive to high frequency improvement.
