[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0019] like Figure 1-5 The illustrated series terminal block includes a main terminal block 1, a terminal block 2, and a cover plate 3. The main terminal block 1 and the terminal block 2 are provided with opposite side slots 10. The main terminal block 1 is provided with a conductive plate 11, and a connecting plate 12 extends laterally from the conductive plate 11. The terminal block 2 is provided with a tap plate 21. The connecting plate 12 is used to electrically connect the tap plate 21. The terminal block also includes an electrical conductive plate 22 located between at least two tap plates 21 for electrical connection. The electrical conductive plate 22 extends from the side slot 10 and electrically connects two adjacent tap plates 21.

[0020] As a further feature of the above scheme, the tapping plate 21 is provided with a slot 23, and the electrical conduction plate 22 is provided with a block 24 that matches the slot 23. The block 24 is elastically oscillating relative to the electrical conduction plate 22.

[0021] As a further provision of the above scheme, the main cable holder 1 and the outlet cable holder 2 are also provided with a retaining spring 13 and a pressure rod 14. The main cable holder 1 and the outlet cable holder 2 are provided with a cable groove 15 and a tool groove 16. The cable groove 15 is provided in the middle of the contact between the retaining spring 13 and the conductive plate 11 or the tapping plate 21. The conductive plate 11 and the tapping plate 21 are provided with a limiting block 18 opposite to the retaining spring 13. The limiting block 18 is used to abut against the retaining spring 13 to limit its swing angle.

[0022] As a further provision of the above scheme, the main line holder 1 and the outlet holder 2 are provided with mounting grooves 31 and positioning blocks 32 at their bottoms, and also include adapter brackets 33 or fixing bases 34 for fixing the wiring terminals. The adapter bracket 33 is provided with a snap-fit ​​groove 35 at its bottom that matches the external rail. The fixing base 34 is provided with screw holes 36. The adapter bracket 33 or fixing base 34 is provided with a positioning groove 38 that matches the positioning block 32.

[0023] As a further feature of the above scheme, the inner cavity groove 27 of the cable outlet 2 for mounting the tap plate 21 is also provided with a groove 26, and the tap plate 21 is provided with a block 25 that matches the groove 26. The cable outlet 2 is provided with a tap post 28 and a tap groove 29 on both sides respectively.

[0024] The most significant feature of the terminal block in this embodiment, as described above, is that a set of main connectors 1 can hold the conductive cable in place, and then any set of outlet connectors 2 can be reinstalled, thereby achieving a one-in-multiple-out wiring configuration. Furthermore, in use, the terminal block structure allows for quick and convenient addition or removal of outlet connectors 2 as needed. Both the main connectors 1 and outlet connectors 2 employ a cable-clamping design, facilitating cable installation. The cable-clamping structure uses a pressure rod 14, which can be released from the cable clamping structure by applying pressure with a conventional screwdriver or a thin object, allowing for quick cable extraction.

[0025] Furthermore, based on the above, the most basic configuration and usage of the terminal block in this embodiment is a one-in-multiple-out wiring method, which is the basis of the product design of this embodiment. However, the terminal block in this embodiment can also be flexibly used without installing the electrical conduction plate 22 between adjacent outlet terminals 2. When the electrical conduction plate 22 is not installed, no electrical series connection is generated between the terminal blocks, and it can be used as an ordinary terminal block. Furthermore, depending on the usage requirements, the electrical conduction plate 22 can be installed or not, providing a variety of flexible implementation and usage methods.

[0026] like Figure 2 and Figure 3 Each set of outlet sockets 2 shown in this embodiment is independently provided with a housing, a tap plate 21, a retaining spring 13, and a pressure rod 14. The housing has a side slot 10 on its side opposite to the tap plate 21. An electrical conduction plate 22 is also provided between two adjacent outlet sockets 2, such as... Figure 3 As shown, the electrical conduction plate 22 has a locking block 24 at both ends. The locking block 24 is matched and connected with the locking slot 23 on the tapping plate 21. The electrical conduction plate 22 is set between two adjacent outlet sockets 2, thereby realizing the electrical connection between the two outlet sockets 2.

[0027] Furthermore, based on the above, the retaining spring 13 is mounted on the housing in an M-shape, and the pressure rod 14 is positioned directly opposite the retaining spring 13 from the upper tool slot 16. Under the application of external force, the pressure rod 14 drives the retaining spring 13 to deform and create a gap groove with the tap plate 21. This gap groove is directly opposite the cable slot 15. Thus, after the cable is inserted, the external force on the pressure rod 14 is released, and the retaining spring 13 returns to its original shape. This not only resets the pressure rod 14, but the elastic force generated by the deformed retaining spring 13 also acts on the inserted cable, pressing it tightly against the tap plate 21, thus achieving tight contact and conduction between the cable and the tap plate 21.

[0028] refer to Figure 2 As shown, the bottom of the terminal block in this embodiment is also provided with an adapter bracket 33 or a fixing bracket 34 for installation. The adapter bracket 33 and the fixing bracket 34 are the same as the bottom of the main wire socket 1 and the outlet socket 2 of the terminal block, the difference being that the fixing structure relative to the mounting surface is different, such as... Figure 2The adapter bracket 33 shown is mainly configured with a snap-fit ​​groove 35 for snap-fit ​​installation with an external rail, while the bottom of the fixed base 34 is provided with screw holes 36, so that it can be fastened to the mounting surface by screws. In addition, in order to ensure a stable connection between the adapter bracket 33 or the fixed base 34 and the terminal block, a positioning block 32 structure is also provided at the bottom of the main line base 1 and the outlet base 2, and a corresponding positioning groove 38 is provided on the adapter bracket 33 or the fixed base 34, so as to achieve stability during installation and use.

[0029] refer to Figure 2 and Figure 4 As shown, when the terminals in this embodiment are used in series, the connection method includes a certain connection formed simultaneously by the electrical connection of the electrical conduction plate 22. The connection is mainly formed by the tap 28 and tap groove 29 provided on the side of the outlet 2. In addition, an inner cavity groove 27 is provided on the housing of the outlet 2 for the installation of the tap plate 21. The inner cavity groove 27 is also provided with a groove 26 that matches the insert 25 on the tap plate 21 to stably install the tap plate 21.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
