[0004] However, when a terminal block such as that described in Patent Document 1 is installed in a distribution board for secondary power transmission of the distribution board, the incoming and outgoing directions of the wiring are restricted. In particular, the wiring for power transmission is thick because it is necessary to transmit a large amount of power, and if the wiring is bent, a large wiring space must be secured. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present invention have made extensive research into this point and have attempted to solve the problem. The problem that the present invention aims to solve is to provide a terminal block with an increased degree of freedom in the wiring direction. [Means for solving the problem]

[0006] In order to solve the above problems, a terminal block is provided which includes a rotation restriction portion which restricts the wiring direction from one side to the terminal portion to within a range of approximately right angles, and a wiring insertion portion through which wiring can be inserted from the other side to the terminal portion, and which has a wiring insertion portion provided so that wiring from the other side to the terminal portion can be inserted from two directions which are approximately perpendicular to each other.

[0007] It is also preferable to provide an upward movement restricting portion capable of restricting the upward movement of the wires passing through the wire insertion portion.

[0008] In addition, it is preferable that the approximately right angle formed between the wiring route from one wiring insertion portion to the terminal portion and the wiring route from the other wiring insertion portion to the terminal portion is formed at a position that is linearly symmetrical with the approximately right angle in the range in which the rotation control portion controls the wiring direction from one side to the terminal portion.

[0009] It is also preferable to have three terminal portions, which are positioned on the same straight line in a planar view, with the terminal portion located in the middle in a planar view being formed higher than the terminal portions located on either side, and to have a wiring insertion portion below a bottom surface formed in one of the two wiring insertion portions through which a wire can be inserted when connecting the wire to the terminal portion located in the middle, through which a wire can be inserted from a direction different from the direction in which the wire is connected to the terminal portion located in the middle when connecting the wire to one of the terminal portions located on the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The following describes an embodiment of the invention. As can be understood from Figs. 1 to 5, the terminal block 1 of this embodiment includes a rotation restriction portion 11 that restricts the wiring direction from one side to the terminal portion 14 within a range of approximately right angles, and a wiring insertion portion 12 through which wiring from the other side to the terminal portion 14 can be inserted. In addition, the terminal block 1 is provided with the wiring insertion portion 12 so that wiring from the other side to the terminal portion 14 can be performed from two directions that are approximately perpendicular to each other. This makes it possible to provide the terminal block 1 with an increased degree of freedom in the wiring direction. Furthermore, the use of this terminal block 1 makes it possible to save space for wiring and optimize wiring to devices arranged in various positions.

[0013] Here, the terminal block 1 of the embodiment will be described. In the following, the terminal block 1 in which the conductive bar 61 and the electric wire 62 are connected to the terminal portion 14 from different directions will be described as an example. The terminal block 1 of the embodiment has a generally triangular shape in a plan view, and is provided with steps so that wiring can be separated in the upper and lower directions of the terminal block 1. The terminal block 1 also includes a terminal portion 14 in which a hole portion 13 that is hexagonal in a plan view and into which a hexagonal nut can be embedded is formed. The lower direction of the terminal block 1 refers to the surface side to which the terminal block 1 is fixed as viewed from the terminal portion 14.

[0014] This terminal block 1 includes a terminal block fixing portion 15 used for fixing the terminal block 1. The terminal block fixing portion 15 in the embodiment is a screw insertion hole for screwing and fixing the terminal block 1. In a plan view, the terminal block fixing portion 15 in the embodiment is provided between the center hole 13 of the three lined up holes 13 and the holes 13 on both ends. After being placed in a location within the board where it is to be fixed, the terminal block 1 in the embodiment can be fixed by tightening the male screw inserted into the terminal block fixing portion 15.

[0015] The terminal block 1 also includes a rotation restriction portion 11 that restricts the wiring direction of the wires from one side within a range of approximately right angles. To make this possible, the ends of the rotation restriction portion 11 are arranged so as to sandwich a hexagonal hole portion 13 in a plan view.

[0016] In the terminal block 1 of the embodiment, the wiring connected to the wiring from one side is connected to the terminal portion 14 from the other side. Exchange In order to make this possible, the terminal block 1 is provided with a plurality of wire insertion portions 12.

[0017] One side of the terminal block 1 in the embodiment is a side in which wiring is applied to the terminal portion 14 so as to straddle the hypotenuse of the right-angled triangle in plan view. The other side is a side in which wiring is applied to the terminal portion 14 so as to straddle the other two sides different from the hypotenuse of the right-angled triangle in plan view. This structure makes it possible to organize the wiring connected to the terminal portion 14.

[0018] In the embodiment, the terminal block 1 is connected to wiring from which electricity flows toward the terminal block 1 and wiring from which electricity flows from the terminal block 1, but it is not generally assumed that these wirings will be wired from the same direction to one terminal portion 14.

[0019] In addition, in the terminal block 1 of the embodiment, One A wiring route from the wiring insertion portion 12 to the terminal portion 14; other The approximate right angle formed by the wiring route from the wiring insertion portion 12 to the terminal portion 14 is formed at a position that is line-symmetrical with the approximate right angle of the range in which the rotation restriction portion 11 restricts the wiring direction from one side to the terminal portion 14. In other words, the rotation restriction portion 11 is One an extension line of the wiring extending linearly from the wiring insertion portion 12 to the terminal portion 14; other The wiring direction from one side to the terminal portion 14 can be restricted within a range of approximately a right angle to the extension line of the wiring extending in a straight line from the wiring insertion portion 12 to the terminal portion 14. In this way, wiring can be performed in a space-saving manner when the same terminal blocks 1 for power supply are arranged adjacent to each other.

[0020] The terminal block 1 of the embodiment includes three terminals 14, which are aligned in the same line in a plan view, but the terminal 14 located in the middle in a plan view is formed higher than the terminals 14 located on both sides. The terminal block 1 includes a wire insertion portion 12 that allows a wire to be inserted from a direction different from the direction of connection of the wire to the terminal 14 located in the middle when connecting the wire to one of the terminals 14 located on the outside, below a bottom surface 17 formed in one of the two wire insertion portions 12 through which a wire can be inserted when connecting the wire to the terminal 14 located in the middle. This makes it possible to avoid interference between the wire connected to the terminal 14 located in the middle in a plan view and the wire connected to the terminal 14 located on the outside in a plan view. Also, it is possible to ensure an insulation distance between the wires.

[0021] 6, a cover member 51 capable of covering the terminal portions 14 and the like may be attached to the terminal block 1. The terminal block 1 of the embodiment is provided with a cover attachment portion 19 so that the cover member 51 can be attached. The cover attachment portion 19 of the embodiment is formed above the wiring insertion portion 12 that can be used as a path for wiring connected to the terminal portions 14 located on both ends of the terminal block 1.

[0022] In addition, the cover mounting portion 19 in this embodiment is located at the intersection of a straight line connecting the terminal portion 14 on one end side and one wiring insertion portion 12 for this terminal portion 14 and a straight line connecting the terminal portion 14 on the other end side and one wiring insertion portion 12 for this terminal portion 14.

[0023] 7 to 9, the terminal block 1 of the embodiment is configured to have an upward movement restriction portion 16 that can restrict the upward movement of the wires passing through the wire insertion portion 12. This makes it difficult for the conductive bar or other wiring to move upward, and the wiring is prevented from floating up from the terminal block 1. of In addition, when the wiring is connected to the screw inserted into the hole 13 of the terminal portion 14 extending in the vertical direction, the wiring can be prevented from falling off the terminal block 1. In the terminal block 1 of the embodiment, a female screw or a male screw is inserted into the hexagonal hole 13, and after the wiring is connected to the female screw or the male screw, the movement of the wiring so as to slip out of the hole 13 can be restricted, so that it is not necessary to firmly fix the female screw or the male screw using a separate member.

[0024] Moreover, the wiring insertion portion 12 provided on the upper side of the terminal block 1 in the embodiment is formed in a through-hole shape. The movement of the wiring inserted into this through-hole-shaped wiring insertion portion 12 is suppressed by a portion that determines the shape of the wiring insertion portion 12. Note that, in the embodiment, the through-hole-shaped wiring insertion portion 12 is shaped so that the conductive bar 61 can be inserted therein, but it may be shaped so that an electric wire 62 equipped with a crimp terminal 63 can be inserted therein.

[0025] 10, the wire insertion portion 12 is provided with an inclined portion 21 so that the tip of the wire inserted into the wire insertion portion 12 can easily and appropriately face the terminal portion 14. This makes it easier to guide the tip of the wire inserted into the wire insertion portion 12 into the terminal portion 14.

[0026] We have explained an example of terminal block 1, but if such a terminal block 1 is incorporated into a board, it can be used as shown in Figure 11 or Figure 12. For example, if a board with the configuration shown in Figure 11 is changed inside to have the configuration shown in Figure 12, the conventional terminal block 1 can be used and wiring can be performed appropriately.

[0027] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be variously modified. For example, the wiring connected to the terminal block does not need to be a combination of a conductive bar and an electric wire. Both may be conductive bars, or both may be electric wires equipped with crimp terminals.

[0028] Furthermore, the incoming and outgoing directions of the wiring may be determined for each terminal portion, and do not need to be standardized to the same direction.

[0029] Furthermore, the terminal block does not have to have a triangular shape in a plan view, and may have, for example, a rectangular shape in a plan view. [Explanation of symbols]
