[0048] In order to make the drawings concise, each figure only schematically shows the parts related to the utility model, which do not represent the actual structure of the product.
[0049] Figure 1 is a three-dimensional diagram of a schematic embodiment of a wiring frame of a wiring terminal. The wire can be inserted into the wiring frame of the wiring terminal along the insertion direction S. After the wire is inserted, the wiring frame can be installed in a plastic housing and then installed in the switchgear. Figure 1 As shown, the wiring frame includes a first side plate 10, a bottom plate 20, a second side plate 30, a first top plate 40 and a connecting plate 50 connected in sequence along the circumferential direction C. The circumferential direction C is perpendicular to the wiring direction S of the wiring frame. The first side plate 10, the bottom plate 20, the second side plate 30 and the first top plate 40 are surrounded by a cuboid. It can be understood by those skilled in the art that the cuboid described here does not only refer to the strict definition in geometry, and the corners of the cuboid can also be curved. The first top plate 40 is used to be threadedly connected to the wiring screw of the wiring terminal. The bottom plate 20 is used to clamp the wire inserted into the wiring terminal with the wire pressing plate of the wiring terminal. In a schematic factual manner, the wiring frame includes a blocking plate 70. The blocking plate 70 is connected to the bottom plate 20 and extends in a direction away from the first top plate 40. The blocking plate 70 is used to block the wire from being inserted into the side of the bottom plate 20 away from the first top plate 40 along the wiring direction S.
[0050] Figure 2 for Figure 1 A cross-sectional view of the wiring frame is shown in FIG. Figure 2 As shown, the first side plate 10 has an embedding opening 11 that penetrates along its thickness direction. The connecting plate 50 is embedded in the embedding opening 11 in a coplanar manner with the first side plate 10 to prevent the connecting plate 50 from moving relative to the first side plate 10 in a direction parallel to the plate surface. The first side plate 10 is thinned at the edge around the embedding opening 11 to form a first abutment portion 12. The connecting plate 50 is thinned at its edge to form a second abutment portion 52. The second abutment portion 52 is arranged opposite to the first abutment portion 12 along the thickness direction of the first side plate 10 and contacts each other. In an illustrative embodiment, the second abutment portion 52 is located on the side of the first abutment portion 12 that is away from the second side plate 30, and the connecting plate 50 is embedded in the first side plate 10 from the outside during manufacturing, which is more conducive to manufacturing. By setting the first abutment portion 12 and the second abutment portion 52, the wiring frame provided by the utility model has a greater strength when the torque test of the parts is performed after the riveting process is completed, and deformation such as concave or concave will not occur.
[0051] like Figure 3 As shown, in another schematic embodiment of the wiring frame of the wiring terminal, the wiring frame also includes a second top plate 60. The two ends of the first side plate 10 along the circumferential direction C are respectively connected to the bottom plate 20 and the second top plate 60. The second top plate 60 is stacked in parallel on the side of the first top plate 40 facing the bottom plate 20. The second top plate 60 is used to be threadedly connected with the wiring screw. The plate surface of the first top plate 40 and the second top plate 60 is perpendicular to the height direction H of the wiring frame. The end of the second side plate 30 connected to the first top plate 40 has a limiting surface 31. The limiting surface 31 is perpendicular to the height direction H and faces the plate surface of the second top plate 60 facing away from the first top plate 40. The second top plate 60 has a limiting portion 61 in contact with the limiting surface 31. The limiting surface 31 and the limiting portion 61 further improve the strength of the connection when the second top plate 60 is connected with the screw. In a schematic embodiment, a plurality of grooves 21 are formed on the surface of the bottom plate 20 facing the first top plate 40. The extension direction of the groove 21 is perpendicular to the plugging direction S. A plurality of grooves 21 are arranged along the wire insertion direction S to increase resistance when the bottom plate and the wire pressing plate clamp the wire.
[0052] Figure 4 FIG. 1 is a schematic diagram of a schematic implementation of a wiring terminal. Figure 4As shown, the terminal block includes a wiring frame 10, a wiring screw 91 and a wire pressing plate 92. The structure of the wiring frame 10 is as described above and will not be repeated here. The first top plate 40 has a threaded through hole. The wiring screw 91 is inserted into the through hole of the first top plate 40 and is threadedly connected to the first top plate 40. In an illustrative embodiment, the wiring frame includes two limiting ribs 80. The two limiting ribs 80 are respectively formed at the junction of the bottom plate 20 and the first side plate 10 and at the junction of the bottom plate 20 and the second side plate 30. The cross-section of the limiting rib 80 perpendicular to the wire insertion direction S is a triangle. The wire pressing plate 92 is arranged between the first top plate 40 and the bottom plate 20 and is rotatably connected to the wiring screw 91. The wiring screw 91 rotating relative to the wiring frame can drive the wire pressing plate 92 to move toward the bottom plate 20 and clamp the wire inserted into the terminal block with the bottom plate 20.
[0053] Figure 5 FIG. 1 is a schematic structural diagram of a schematic implementation of a wire clamp in a wiring frame of a wiring terminal. Figure 5 As shown, the wire pressing plate 92 has two notches 921 arranged opposite to each other. The limiting rib 80 is inserted into the notches 921 of the wire pressing plate 92 of the wiring terminal to limit the movement of the wire pressing plate 92 along the wire insertion direction S relative to the wiring frame.
[0054] Figure 6 The schematic diagram of the structure of the plate of the wiring frame of the wiring terminal before bending. In order to facilitate manufacturing, the wiring frame of the utility model can be formed by bending the same plate. Figure 5 The plate in the figure includes, from top to bottom, a second top plate 60 with holes for inserting screws, a first side plate 10 with an insertion opening, a bottom plate 20, a second side plate 30, a first top plate 40, a connecting plate 50, and a second abutting portion 52.
