Specifically, the invention enables the application of grounding terminals with varying numbers of mounting holes to standard DIN rails. A cover that insulates conductive connection points, ensuring safe use on the surface. Rail mounting clip, 10, allows for cable connection, screw tightening, and maintenance without disassembly. locking clip, side mounting holes, cable entry openings, insulated divider, and screwdriver. It relates to an insulated terminal block protective cover and terminal block system containing access holes. State of the Art Manufacturing of electrical panels, fuse boxes, distribution panels and field installation applications. Terminal blocks are widely used for connecting conductors in an orderly, safe and standardized manner. 15 These terminals are used in multiple ways, especially in grounding and power distribution lines. the accumulation of excess conductors on the same junction block and an orderly electrical system within the panel It enables the creation of a connection pattern. Grounding terminals used in current technology are mostly made of brass or similar conductive metal. They are manufactured from alloys and have varying numbers of cable connection holes, with 20 cables per hole. Corresponding mounting screws are included. These terminals are mounted on a standard DIN rail. It can be positioned or fixed to the panel surface. However, conductive metal In most applications, the housing and connecting screws provide the user, maintenance personnel, or assembly team with the necessary support. It can remain open to its staff. Leaving conductive connection points exposed increases the risk of electrical contact during assembly and maintenance. increasing, reducing the level of security inside the panel, and especially in demanding field conditions, the job This can lead to undesirable situations in terms of safety. Furthermore, exposed conductive surfaces... Exposure to dust, moisture, impact, or internal panel movements can affect connection reliability and equipment performance. This can negatively affect long-term performance. In bare terminal block applications without an insulated protective cover, the conductive metal housing and 30 The connecting screws can come into direct contact with the user's hand or the assembly equipment. It remains exposed. This type of exposed structure means that the terminal block is completely exposed while operations are being performed inside the panel. 2 This leads to them being found naked, making the need for isolation technically necessary. It brings. Although some terminal blocks use insulated covers in common applications, these covers are mostly... Sometimes it has to be completely disassembled during maintenance or screw tightening operations. 5 Removing the cover leaves the connection points temporarily exposed, making assembly difficult. this prolongs the process, creates the risk of losing covers or screws, and causes the operator to become entangled in the conductive material. This causes it to work close to surfaces. In current products, the cover structure of the cable entry areas and screwdriver access areas is designed accordingly. The fact that it is not organized together and in a controlled manner is also a significant disadvantage. Cable connection 10 Insufficient access to the cover during the process, preventing the terminal from being removed from the insulated structure. or may require the cover to be removed; this affects both ergonomics and electrical performance. It negatively affects security. Another problem is that terminal blocks are manufactured with variations that have different numbers of connection holes. The problem is that most protective cover designs are dependent on a specific number of holes. 15 This situation necessitates separate and narrow covers for terminals with varying numbers of connection holes. This requires solutions, complicates production and inventory management, and the same technical security This limits the application of its advantage to different terminal sizes. In current applications, the cover, hole pattern, and rail clip geometry must be combined to form a compact housing. The inability to resolve the issue within the system, the product taking up excessive space inside the panel, or requiring additional connections. 20 This can lead to the need for additional parts. Therefore, the hole pattern and cable access... openings, screwdriver access holes and rail snapping / locking clips are integrated and compact. It is important that it is arranged on an insulated cover structure. Furthermore, in DIN rail-mounted systems, the clip geometry ensures retention on the rail. There are situations where it is not sufficient on its own; vibration, cable pulling force, or inside the panel 25 An additional locking mechanism is needed to prevent the product from derailing under impact. It is heard that the side mounting holes are either missing or not functionally positioned. In these solutions, however, it becomes difficult to fix the product to the panel surface with screws. Therefore, it can be used in conjunction with grounding terminals that have different numbers of holes. Tightening screws and cable connections without removing the cover, insulating the conductive connection points. 30 Locking clip that allows for operation, fits on DIN rails, and prevents derailment. a panel containing and, if necessary, can be fixed to the panel surface with screws via side mounting holes. A rail-mounted insulated terminal block protective cover and terminal block system are required. 3 In addition, there are smart sensor terminals, waterproof conical spring cable splice elements, Communication or battery compartment solutions under the terminal cover used in meters and overhead lines. Terminal blocks are also known. However, these structures are used for electronic monitoring and directly connecting cable ends. 5 different problems such as merging, meter module housing or overhead power connection It is intended for and includes grounding terminals with different hole numbers used in switchboards and fuse boxes. the need for protection within an insulated cover and access without removing the cover It does not meet the requirements. In the known state of the art, conductor entries, bridges, junction boxes, springs and connections Terminal structures, which include a cover that acts as a shroud on at least one of their sockets, are also 10 It is known that such structures cover spring cable connection sockets or the spring of the conductor. Designed for connection with force; cable entry openings, screwdriver access holes, DIN Rail mounting clip, locking clip and side mounting holes are all on the same insulated cover body. It does not offer an integrated protection system with a variable number of holes. In the known state of the art, panel-mounted rail terminals also have plastic housings, copper or brass 15 bridge, spring or push-in fittings, serrated nut-bolt arrangement, openable and closable Solutions that include covers, probe holes, foot plastic, or breakable body parts These structures are essentially the internal electrical connections, distribution, testing, or push-in of the rail terminal block. It is intended for cable retention arrangements and the existing connection arrangement of the screw grounding terminal. External isolation without modification, access hole geometry compatible with different hole numbers 20 It does not meet the requirements for creation and assembly / service without removing the cover. In the current state of the art, a housing, busbar, and cable connection can be mounted on a DIN mounting rail. with feet, cable clamping screws, compression springs, metal legs and body cover. Grounding terminals are known. In these designs, the housing cover is the body of the terminal itself. It is arranged as part of the structure; contact with the mounting rail, current busbar and metal feet 25 This is provided via screw grounding with different hole numbers. However, these solutions involve screw grounding with different hole numbers. Externally adaptable to terminal blocks, insulating the bare conductor terminal block, screw-on without removing the cover. Locking clip and side attachment that provides clamping and cable access, and also prevents derailment. an integrated insulated protective cover structure that offers secure mounting through its holes It does not meet the requirements. 30 Brief Description of the Invention The present invention provides electrical panels, fuse boxes, and other components that meet the aforementioned needs.
