[0020] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. In this process, the size or shape of components illustrated in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, terms specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intent or convention of the user or operator. The definitions of such terms should be based on the content throughout this specification.

[0021] FIG. 1 is a perspective view of a terminal block according to one embodiment of the present invention, FIG. 2 is an exploded perspective view of a terminal block according to one embodiment of the present invention, and FIG. 3 is a side view of a terminal block according to one embodiment of the present invention.

[0022] Referring to FIGS. 1 to 3, a terminal block according to one embodiment of the present invention includes a terminal block housing (10) and an integrated terminal (20) that is inserted into and assembled in the terminal block housing (10).

[0023] The terminal block housing (10) includes a main body (12) to which a power input cable is connected on one side and a plurality of power output cables are connected on the other side, a support part (14) formed on both edges of the main body (12) and formed to be higher than the upper surface of the main body (12), a top plate part (16) formed at a certain distance from the upper surface of the main body (12) and having both ends connected to the support part (14), and an insertion passage part (46) formed between the main body (12) and the top plate part (16) to which an integrated terminal (20) is inserted.

[0024] The integrated terminal (20) is structured such that assembly to the terminal housing (10) is completed when it is inserted into the insertion passage (46) in the lateral direction of the terminal housing (10), and includes a terminal body part (22) having the same length as the insertion passage (46), a first connection terminal part (24) that extends forward from the center of one side of the terminal body part (22) to which a power input side cable is connected, and a second connection terminal part (26) that extends backward from the other side of the terminal body part (22) and is formed in multiple numbers at regular intervals to which a plurality of power output side cables are connected.

[0025] Since such an integrated terminal (20) is formed as a single body and assembly is completed by inserting it into the insertion passage (46) in the lateral direction of the terminal block housing (10), assembly is easy and convenient. That is, in the case of conventional methods, since multiple terminals must be assembled one by one into the terminal block housing (10) corresponding to the number of power output cables, assembly time is long and manufacturing costs increase. However, according to the present embodiment, assembly is completed by inserting the integrated terminal into the terminal block housing, making assembly easy and reducing manufacturing costs.

[0026] Here, the first connection terminal part (24) is formed as a structure with two parts in the drawing, but it is also possible to form only one part.

[0027] The main body (12) of the terminal block housing (10) has a first terminal mounting part (30) formed on one side where a first connection terminal part (24) is located, and a plurality of second terminal mounting parts (32) formed on the other side where a plurality of second connection terminal parts (26) are located. The first terminal mounting part (30) has a first bolt groove part (40) into which a bolt is inserted when the first connection terminal part (24) and the power input side cable are bolted together, and the second terminal mounting part (32) has a second bolt groove part (42) into which a bolt is inserted when the second connection terminal part (26) and the power output side cable are bolted together.

[0028] A partition plate (34) is vertically formed on the other edge of the main body (12) to divide and insulate between a plurality of second connection terminal parts (26), and a catch portion (36) is formed on the other side of the main body (12) so as to prevent the integrated terminal (20) from coming off by causing the integrated terminal (20) to be caught when the integrated terminal (20) is inserted into the insertion passage (46).

[0029] The top plate (16) forms an insertion passage (46) into which the integrated terminal (20) is inserted, and also serves to cover the terminal body (22) of the integrated terminal (20).

[0030] The length (L1) of the first connection terminal part (24) of the integrated terminal (20) is formed to be shorter than the length (L2) of the second connection terminal part (26), and the top plate part (16) is removed from the upper surface portion of the terminal body part (22) to which the first connection terminal part (24) is connected, so that a part of the terminal body part (22) acts as the first connection terminal part (24).

[0031] Therefore, when the integrated terminal (20) is assembled to the terminal block housing (10), the length of the first connection terminal part (24) and the length of the second connection terminal part (26) are the same, so that the power input side cable and the power output side cable are connected in the same way.

[0032] FIG. 4 is a perspective view showing a terminal block assembled in two stages according to one embodiment of the present invention, and FIG. 5 is a perspective view of a part of a terminal block according to one embodiment of the present invention.

[0033] A terminal block connection part is formed in the support part (14) for assembling terminal blocks in multiple stages. That is, since only one integrated terminal is installed in the terminal block, when connecting the positive power and the negative power during power connection, two terminal blocks are assembled in the vertical direction to connect the positive power and the negative power. In addition, the number of terminal blocks can be increased by stacking multiple terminal blocks in multiple stages.

[0034] The terminal block connection part includes a stepped portion (50) formed on one side of the support portion (14) and formed to be lower in height than the support portion (14), a fitting groove portion (56) formed on the lower surface of the stepped portion (50), a fitting projection portion (52) protruding from the upper surface of the support portion (14) and fitted into the fitting groove portion (56), a position alignment plate portion (54) protruding vertically from the side of the support portion (14) to align the position when assembling a plurality of terminal blocks, and a position alignment slot portion (60) formed in a concave shape on the lower surface of the support portion (14) into which the position alignment plate portion (54) is inserted.

[0035] When assembling terminal blocks in two stages, the device includes a lower terminal block (100) located at the bottom and an upper terminal block (110) assembled on the upper surface of the lower terminal block (100). Of course, it is also possible to form multiple stages by assembling additional terminal blocks on top of the upper terminal block (110).

[0036] The support portion (14) is formed at both ends of the first terminal mounting portion (30) of the main body portion (12), and the step portion (50) is formed at both ends of the second terminal mounting portion (32). At this time, when the upper terminal block (110) is assembled to the upper surface of the lower terminal block (100), the fitting groove portion (56) formed on the lower surface of the step portion (50) of the upper terminal block (110) is inserted into the fitting projection portion (52) formed on the support portion (14) of the lower terminal block (100) and assembled together. That is, the second terminal mounting portion (32) of the upper terminal block (110) is assembled so as to be stacked on the upper surface of the first terminal mounting portion (30) of the lower terminal block (100). Accordingly, when the upper terminal block (110) is assembled on the upper surface of the lower terminal block (100), the second terminal mounting portion (32) of the lower terminal block (100) is positioned in a protruding and exposed manner.

[0037] Therefore, even if the terminal blocks are stacked in multiple layers, the second terminal mounting portion (32) of the lower terminal block (100) is exposed, making it easy to connect multiple power output side cables to the multiple second connection terminal portions (26) formed in multiple layers.

[0038] Since assembly is completed by fitting another terminal block onto the upper surface of one terminal block, such a terminal block connection is easy and allows for the formation of multiple terminal blocks.

[0039] Although the present invention has been illustrated and described above with reference to specific preferred embodiments, the present invention is not limited to the above-mentioned embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit of the invention.
