Description

Technical Field

[0001] This utility model relates to the field of power connection equipment, and in particular to a terminal block. Background Technology

[0002] Terminal blocks (also known as terminal blocks or terminal strips) are a basic component that plays a key role in the centralized management, fixation and distribution of electrical circuits, aiming to achieve high reliability of electrical signal or power transmission. In existing conventional designs, terminal blocks are installed by opening terminal slots, and then plastic sleeves are fitted onto the terminals. The terminals are then fixed by interference fit between the plastic sleeves and the terminal slots. However, in practice, fixing with plastic sleeves has obvious limitations. During daily operation, the terminals are prone to slight movement. Therefore, the industry generally uses additional locking clips (such as terminal fixing pieces or secondary locking clips) for reinforcement, or applies adhesive to fix the terminals. However, using existing technology to fix terminals with clips or glue is extremely inconvenient during maintenance and disassembly, and may even cause damage to the entire terminal block due to violent disassembly, significantly increasing maintenance costs. In addition, when installing the terminal block to the equipment base plate, it usually requires the use of bolts for mechanical fixation. During daily operation, the screws on the terminal block are prone to slight rotation, which can loosen them and cause friction. At the same time, temperature changes and mechanical vibrations can cause fretting friction between the terminals and conductors. Furthermore, friction can also occur between the metal tools and the bolts during tightening or subsequent maintenance. Bolts are prone to generating static electricity during friction. This static electricity can couple to adjacent terminals through arc discharge, forming an electrostatic arc, which can eventually break down sensitive electronic equipment connected to the back end, causing irreversible damage.

[0018] This utility model embodiment provides a terminal block.

[0019] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.

[0020] A terminal block includes a mounting base 100, a power transmission assembly 200, a cover 300, a flexible locking member 400, and a grounding spring 500. The mounting base 100 has a mounting cavity on one side and a plurality of mounting slots 101, in which a power transmission component 200 is disposed. The mounting base 100 is provided with a plurality of slots 102, and the slots 102 are located between two adjacent mounting slots 101 and communicate with the corresponding two mounting slots 101. A disassembly hole 102a communicating with the slot 102 is provided on one side of the slot 102. The elastic locking member 400 is disposed in the slot 102 and is engaged between two adjacent power transmission components 200. At least two protrusions 41 are provided on one side of the elastic locking member 400, and the protrusions 41 abut against the power transmission components 200 to fix the power transmission components 200. The elastic locking component 400 is provided with a disassembly groove 42 and a force application groove 43.

[0021] In daily operation, the screws securing the terminals in terminal blocks are prone to slight rotation, leading to loosening. Furthermore, temperature changes and mechanical vibrations can cause fretting wear between the terminals and conductors, resulting in increased contact resistance and decreased connection reliability. Existing technologies use additional locking clips (such as terminal fixing pieces or secondary locking clips) for reinforcement, or apply adhesive to fix the terminals. However, the existing technology of locking the terminals or fixing them with glue is extremely inconvenient during maintenance and disassembly, and may even cause damage to the entire terminal block and render it unusable due to violent disassembly. Therefore, this device is equipped with a flexible locking component 400. Specifically, during assembly, several power transmission components 200 are first inserted into the corresponding mounting slots 101, and then the power transmission components 200 are fixed to the mounting base 100. After all the power transmission components 200 are fixed, like Figure 7 As shown, the elastic locking member 400 is installed into the slot 102. During the installation process, the inclined surface of the protrusion 41 contacts and presses against the power transmission component 200. At this time, the locking member 400 is subjected to force as a whole. Because the elastic locking member 400 is provided with a disassembly groove 42, At this point, the two sides of the locking component 400 will move towards the disassembly groove 42, so that the plane of the protrusion 41 can abut against the power transmission component 200. The flat surface of the protrusion 41 then presses against the power transmission component 200, causing the power transmission component 200 to abut against the side of the mounting groove 101. This achieves the limiting and fixing of the power transmission component 200, preventing wear caused by slight movements of the power transmission component 200. When maintenance is required on this device, such as Figure 8As shown, the worker applies force to the retaining member 400 through the disassembly hole 102a. Due to the disassembly groove 42, the protrusion 41 can disengage from its contact with the power transmission component 200. The worker then uses a tool through the force application groove 43 to release force on the retaining member 400, allowing it to be removed from the slot 102, thus completing the disassembly of the retaining member 400. This avoids the problems associated with existing technologies that use clips or adhesive to fix terminals, which are extremely inconvenient for maintenance and disassembly, and may even cause damage to the entire terminal block due to violent disassembly.

[0022] Preferably, the power transmission component 200 is provided with a fixed notch 21a; The fixing notches 21a of two adjacent power transmission components 200 can form a fixing channel. The elastic locking member 400 passes through the fixing channel and uses the protrusion 41 to push the power transmission component 200 against the side wall of the mounting groove 101 to fix the power transmission component 200.

[0023] Example 2, Based on the above embodiment 1, as follows Figures 2-4 As shown; Preferably, the cover 300 is connected to the mounting base 100 via a fixing assembly 301. The cover 300 can cover the mounting cavity of the mounting base 100; The fixing component 301 is inserted with the grounding spring 500, and the fixing component 301 abuts the grounding spring 500 against the mounting base 100.

[0024] Preferably, the fixing component 301 includes an anti-loosening screw 32, a plastic sealing nut 33, and a fixing screw 34; the cover 300 is rotatably connected to the mounting base 100; The anti-loosening screw 32 is screwed onto the mounting base 100 via the plastic sealing nut 33, and the anti-loosening screw 32 passes through the cover 300 to fix the cover 300. The fixing screw 34 is screwed onto the plastic-sealed nut 33, and the grounding spring 500 is connected to the fixing screw 34.

[0025] Specifically, in order to quickly and easily install the power transmission component 200 into the mounting slot 101, the mounting base 100 needs to have one side of the mounting cavity set as an open surface. To prevent dust, moisture, and other impurities from adhering to the power transmission component 200 installed in the mounting base 100 during operation, this device is equipped with a cover 300. The cover 300 covers the mounting cavity of the mounting base 100 and is rotatably connected to the mounting base 100. Furthermore, to ensure the stability of the cover 300 during operation of this device, it is necessary to fix the cover 300 in place using a fixing assembly 301 consisting of anti-loosening screws 32, plastic sealing nuts 33, and fixing screws 34. Specifically, before the power transmission component 200 is installed in the mounting slot 101, the cover 300 is in the position of... Figure 4 The "open state" is shown. After installation, the cover 300 is pushed to cover the mounting cavity of the mounting base 100. In order to ensure the stability of the cover 300, the anti-loosening screw 32 is passed through the fixing hole of the cover 300. Then, the plastic sealing nut 33 and the fixing screw 34 work together with the anti-loosening screw 32 to stably fix the cover 300. Furthermore, since this device typically requires bolts for fixing during actual installation, the screws on the terminal block are prone to slight rotation during daily operation, leading to loosening and friction. Simultaneously, temperature changes and mechanical vibrations can cause fretting friction between the terminals and conductors. Additionally, friction also occurs between the metal tools and bolts during tightening or subsequent maintenance. Bolts are prone to generating static electricity during friction. This static electricity can be connected to the power transmission component 200 through arc discharge, forming an electrostatic arc, which can eventually break down the electronic equipment connected to the power transmission component 200, causing irreversible damage. Therefore, the device is also equipped with a grounding spring 500. When the device is used and installed, the grounding spring 500 is connected to the preset grounding component. Then, when the anti-loosening screw 32 and the fixing screw 34 rub against each other, the static electricity generated will be transmitted to the preset grounding component through the grounding spring 500. This avoids the problem of static electricity being generated in the prior art, which can form an electrostatic arc and damage electronic equipment.

[0026] Example 3, Based on the above embodiment 2, such as Figures 5-10 As shown; Preferably, the power transmission component 200 includes a power terminal 21 and a connection component 22. The power terminal 21 is inserted into the mounting slot 101, and one end of the power terminal 21 passes through the mounting base 100 and protrudes from the mounting base 100; The fixed notch 21a is provided on the power terminal 21; The connecting component 22 is connected to the mounting base 100, and the connecting component 22 passes through the power terminal 21 to fix the power terminal 21.

[0027] Preferably, the connecting assembly 22 includes a combination screw 221, a square nut 222, and a connecting terminal 223; the power terminal 21 is provided with a bent portion 211; The combined screw 221 passes through the bent portion 211 and is screwed to the mounting base 100. The combined screw 221 is connected to the connecting terminal 223, and the connecting terminal 223 abuts against the bent portion 211. The square nut 222 is fitted onto the combined screw 221 and abuts against the bent portion 211, and one side of the square nut 222 abuts against the mounting base 100.

[0028] Preferably, the bent portion 211 is provided with at least two opposing limiting protrusions 211a, and the bent portion 211 abuts against the square nut 222 through the limiting protrusions 211a.

[0029] Specifically, before installing the power terminal 21 into the mounting slot 101, the square nut 222 is pushed into the bending portion 211 so that the bending portion 211 can wrap around the square nut 222. Then, the connecting terminal 223 is fitted onto the combination screw 221, and then the combination screw 221 is passed through the bending portion 211 and the square nut 222 in sequence. Then insert the power terminal 21 into the mounting slot 101, and align the combination screw 221 with the preset threaded groove of the mounting base 100. Then rotate the combination screw 221 until the connection terminal 223 can stably abut against the bent part 211. This achieves the installation of the connection terminal 223, and at this time, the combination screw 221 also locks the power terminal 21 through the square nut 222, thereby achieving auxiliary fixation of the power terminal 21 and further ensuring the stability of the power terminal 21. Furthermore, in actual operation, the square nut 222 is prone to rolling, making it impossible for the combination screw 221 to pass quickly and simultaneously through the square nut 222 and the bent portion 211 of the power terminal 21. Therefore, the bending portion 211 is provided with a limiting protrusion 211a. When the square nut 222 is pushed into the bending portion 211, the limiting protrusion 211a can limit and compress the square nut 222, so that the square nut 222 will not easily detach from the bending portion 211. This facilitates the installation of the combination screw 221. Furthermore, when it is necessary to disassemble the power terminal 21, the square nut 222 will not detach from the bent part 211 without external force.
