[0031] like Figure 1-Figure 5As shown, the utility model provides a terminal block, including an arc plate 20 and at least two wiring terminals 10, the arc plate 20 having an outer arc surface and an inner arc surface. At least two wiring terminals 10 are connected to the arc plate 20 in sequence along the extension direction of the arc plate 20, the wiring part of the wiring terminal 10 is located on one side of the inner arc surface, the angle between the wiring terminal 10 and the tangent direction of the arc plate 20 and the connection point thereof is greater than 45° and less than or equal to 135°, the wire terminal 10 passes through the arc plate 20 along the normal direction of the arc plate 20 and is connected to the arc plate 20, the wiring terminal 10 has a wiring part for connecting with a wire, and the wiring part is located on one side of the inner arc surface.
[0032] It can be understood that the utility model sets the arc plate 20 and the terminal block 10 so that the terminal block 10 passes through the arc plate 20 along the normal direction of the arc plate 20. Since the wire and the terminal block 10 are connected in a perpendicular manner to each other, and the angle between the tangent direction of the terminal block 10 and the arc plate 20 and its connection is greater than 45° and less than or equal to 135°, the wires connected to the terminal block 10 are all tilted upward or vertically upward, avoiding the wires extending in the horizontal direction and interfering with the components around the terminal block. Therefore, there is no need to leave space around the terminal block, and components can be directly arranged around it, thereby improving the space utilization rate in the electrical equipment.
[0033] In some embodiments, only one or more arc-shaped plates 20 may be provided in the terminal row. When multiple arc-shaped plates 20 are provided, the multiple arc-shaped plates 20 are stacked on each other to form a connection mechanism with multiple wiring positions.
[0034] In some embodiments, the terminal block 10 includes a bolt 11, a nut 14, a washer 12, and a pressing plate 13. A through hole is provided on the arc plate 20. The bolt 11 is sequentially inserted into the washer 12, the pressing plate 13, and the arc plate 20. The washer 12, the pressing plate 13, and the head of the bolt 11 are all located on one side of the inner arc surface of the arc plate 20. The threaded section of the bolt 11 passes through the washer 12, the pressing plate 13, and the arc plate 20 and is connected to the nut 14 on one side of the outer arc surface. The washer 12, the pressing plate 13, and the head of the bolt 11 together form a wiring portion, and the wire is crimped between the pressing plate 13 and the arc plate 20.
[0035] In some embodiments, the angle between the tangent direction of the terminal block 10 and the arc plate 20 at their connection is 90°, that is, the tangent of the terminal block 10 and the arc plate 20 at their connection is perpendicular, so that the wires connected to the terminal block 10 are all tilted upward, avoiding the wires extending in the horizontal direction and interfering with the components around the terminal row.
[0036] In some embodiments, the curvature of the curved plate 20 is greater than 0 and less than or equal to π.
[0037] It should be noted that the inner arc surface of the arc plate 20 is set upward, and the outer arc surface of the arc plate 20 is set downward. When the curvature of the arc plate 20 is within the range of greater than 0 and less than or equal to π, the tangent of the arc plate 20 gradually extends upward from the central axis in the direction away from the central axis. At the same time, the terminal 10 penetrates the arc plate 20 along the normal direction of the arc plate 20, and the wire and the terminal 10 are connected in a perpendicular manner to each other, so the wire is parallel to the tangent of the arc plate 20. Therefore, in order to make the wire extend from the central axis direction of the arc plate 20 to the direction away from the central axis in an inclined upward or vertically upward state to both sides of the center of the arc plate after the wire is connected to the wiring part, it is necessary to limit the curvature of the arc plate 20 to a range greater than and less than or equal to π, thereby avoiding the wire interference formed by the tangent direction of the arc plate extending crosswise in the direction toward the center of the arc plate.
[0038] In some embodiments, the terminal block includes a base 100, the base 100 has a plurality of beam layers, and the plurality of beam layers are arranged at intervals so that a gap space for inserting the arc plate is formed between every two adjacent beam layers. A corresponding arc plate 20 is arranged in each gap space, and the connection terminal is located in a part of the plug-in and the beam layer on the outer arc surface of the arc plate 20.
[0039] It should be noted that two adjacent beam layers are spaced apart to form a gap space, which is used for installing the curved plate 20 and also for fixing the curved plate 20 .
[0040] In some embodiments, the beam layer includes at least one beam, and one end of the beam that contacts the inner curved surface and / or the outer curved surface of the arc-shaped plate is a curved surface that corresponds to and fits therewith.
[0041] It can be understood that the end of the beam that contacts the inner and outer curved surfaces of the curved plate presents a curved surface that corresponds to them, with the purpose of making the end of the beam completely fit the curved plate 20, so as to improve the degree of fit between the curved plate and the beam, thereby improving the connection stability between the curved plate 20 and the beam, and preventing the two from loosening due to gaps or poor fit.
[0042] In some embodiments, the terminal row includes at least a plurality of arc plates 20, and the plurality of arc plates 20 include at least a first arc plate 21 and a second arc plate 22, the second arc plate 22 is located on one side of the outer arc surface of the first arc plate 21 and is spaced apart from the first arc plate 21, and each of the wiring terminals 10 on the first arc plate 21 and the second arc plate 22 are staggered.
[0043] It can be understood that each terminal block 10 on the first curved plate 21 and the second curved plate 22 are staggered, that is, the first curved plate 21 must be arranged so as not to cover the terminal block 10 of the second curved plate 22 in the extension direction of the wire, so that all the terminal blocks 10 on the terminal row can be wired normally.
[0044] In some embodiments, two spaced-apart connecting terminals 10 are disposed on each of the first arc-shaped plate 21 and the second arc-shaped plate 22 , and the arc length of the first arc-shaped plate 21 is smaller than the arc length between the two connecting terminals 10 on the second arc-shaped plate 22 .
[0045] That is, by making the arc length of the first arc plate 21 smaller than the arc length between the two connecting terminals 1 of the second arc plate 22, and making the first arc plate 21 located directly above the two connecting terminals 10 of the second arc plate 22, the first arc plate 21 and each connecting terminal 10 on the second arc plate 22 are staggered.
[0046] In some embodiments, the terminal row includes a first curved plate 21, a second curved plate 22, a first beam layer 31, a second beam layer 32 and a third beam layer 33, the first curved plate 21 is arranged between the first beam layer 31 and the second beam layer 32, and the second curved plate 22 is arranged between the second beam layer 32 and the third beam layer 33.
[0047] In some embodiments, the arc plate 20 includes a first arc plate 21, which is located in the gap space between the first beam layer 31 and the second beam layer 32. The first beam layer 31 has one beam, and the beams in the first beam layer 31 are arranged in the middle of the first arc plate 21. That is, the first arc plate 21 is the uppermost arc plate 20 in the terminal row. The number of beams in the second beam layer 32 is the same as the number of connection terminals arranged on the first arc plate 21 along the arc length direction, and each beam is arranged along the width direction of the arc plate 20.
[0048] It should be noted that the width direction and the arc length direction of the arc plate 20 are perpendicular to each other.
[0049] In some embodiments, the terminal row includes a first arc-shaped plate 21, a second arc-shaped plate 22, and a third arc-shaped plate 23. The first arc-shaped plate 21, the second arc-shaped plate 22, and the third arc-shaped plate 23 are stacked, and the center of the first arc-shaped plate 21, the center of the second arc-shaped plate 22, and the center of the third arc-shaped plate 23 coincide with each other.
[0050] In some embodiments, the terminal row includes a first arc plate 21, a second arc plate 22, and a third arc plate 23. The first arc plate 21, the second arc plate 22, and the third arc plate 23 are stacked, and the center of the first arc plate 21 and the center of the second arc plate 22 coincide with each other.
[0051] In some embodiments, the terminal row includes a first arc plate 21, a second arc plate 22, and a third arc plate 23. The first arc plate 21, the second arc plate 22, and the third arc plate 23 are stacked, and the center of the second arc plate 22 and the center of the third arc plate 23 coincide with each other.
[0052] In some embodiments, the terminal row includes a first curved plate 21, a second curved plate 22, and a third curved plate 23, which are stacked and the centers of the first curved plate 21 and the third curved plate 23 coincide with each other.
[0053] In some embodiments, the terminal row includes a first arc plate 21, a second arc plate 22, and a third arc plate 23. The first arc plate 21, the second arc plate 22, and the third arc plate 23 are stacked, and the center of the first arc plate 21, the center of the second arc plate 22, and the center of the third arc plate 23 do not overlap with each other.
[0054] In some embodiments, the terminal row includes a first arc plate 21, a second arc plate 22, and a third arc plate 23. The first arc plate 21, the second arc plate 22, and the third arc plate 23 are stacked, and the arc lengths of the first arc plate 21, the second arc plate 22, and the third arc plate 23 gradually increase.
[0055] Specifically, the arc lengths of the first arc plate 21 , the second arc plate 22 and the third arc plate 23 gradually increase in an arithmetic progression.
[0056] Specifically, the difference in arc length between the first arc plate 21 and the second arc plate 22 is smaller than the difference in arc length between the second arc plate 22 and the third arc plate 23 .
[0057] It can be understood that the arc lengths of the first arc plate 21 , the second arc plate 22 and the third arc plate 23 gradually increase, so that the arc plate 20 located below one arc plate 20 has enough space to avoid interference between the two.
[0058] In some embodiments, the arc plate 20 has a plurality of connection terminals 10 spaced apart along the width direction of the arc plate 20, and the arc plate 20 has a plurality of partitions 40 spaced apart along the width direction of the arc plate 20, each partition 40 is disposed between two adjacent connection terminals 10 along the second direction to separate the plurality of connection terminals 10 in the column of connection terminals 10 respectively.
