Referring to fig. 3 in conjunction with fig. 2, fig. 3 is a schematic structural diagram of the wire frame 10 shown in fig. 2 at another angle. The wire frame 10 includes a first side plate 11, a second side plate 12, a third side plate 13, and a top plate 14. The first side plate 11 is disposed opposite to the third side plate 13. The second side panel 12 is connected between the first side panel 11 and the third side panel 13. The top plate 14 is connected between the first side plate 11 and the third side plate 13. The top plate 14 is spaced from the second side plate 12. The top plate 14, the first side plate 11, the second side plate 12, and the third side plate 13 enclose the inside of the wire frame 10, that is, the accommodating space 101.

In the present embodiment, the wire frame 10 is an integrally formed structural member, that is, the wire frame 10 is an integral structural member. In another embodiment, the wire frame 10 may be a structural member formed by welding or bonding the first side plate 11, the second side plate 12, the third side plate 13, and the top plate 14.

Referring to fig. 5 again, the wire pressing portion 22 includes a wire pressing surface 221. The pressing surface 221 is a surface of the pressing portion 22 facing away from the urging portion 23. A part or the whole of the crimping surface 221 is wavy. Thus, the roughness of the wire pressing surface 221 of the present embodiment is larger than that of the planar wire pressing surface 221. In other embodiments, a part or all of the pressing surface 221 may have a curved surface shape, a step shape, or another shape.

For example, the pressing surface 221 may also be provided with a plurality of bumps (not shown) arranged at intervals, or a plurality of grooves (not shown) arranged at intervals. Thus, the roughness of the crimping surface 221 can be further improved.

Referring to fig. 6 again, as shown in fig. 5, the force application portion 23 includes a first surface 231, and a second surface 232 and a third surface 233 oppositely disposed. The first face 231 is connected between the second face 232 and the third face 233. In another embodiment, the first surface 231, the second surface 232, and the third surface 233 of the biasing portion 23 may be a single curved surface.

Referring to fig. 5 and 6 again, in the Y-axis direction, the width of the line pressing portion 22 is the first width L1. The width of the urging portion 23 in the Y axis direction is the second width L2. The second width L2 is smaller than the first width L1. In other embodiments, the width of the line pressing portion 22 and the width of the urging portion 23 are not particularly limited.

Referring to fig. 7 to 9, fig. 7 is an assembly view of the wire frame 10 and the press block 20 shown in fig. 2 at an angle. Fig. 8 is an assembly view of the wire frame 10 and the press block 20 shown in fig. 7 at another angle. Fig. 9 isbase:Sub>A sectional view of the wire frame 10 and the compact 20 shown in fig. 7 at the linebase:Sub>A-base:Sub>A. The pressing block 20 is movably connected to the wire frame 10. It is understood that the pressing piece 20 may be connected to the wire frame 10 by rotating, sliding, rolling, or the like. The present embodiment will be described by taking an example in which the pressing piece 20 is rotatably connected to the wire frame 10.

In the present embodiment, the wire pressing portion 22 and the urging portion 23 of the press piece 20 are both located in the accommodating space 101 of the wire frame 10. A part of the urging portion 23 of the presser 20 is located at the bottom of the top plate 14. In fig. 9, the rotating shaft portion 21, the pressing line portion 22, and the urging portion 23 of the press block 20 are schematically illustrated by broken lines.

Further, one end of the rotating shaft portion 21 of the pressure piece 20 is disposed in the first rotating shaft groove 111 of the first side plate 11, and the other end of the rotating shaft portion 21 is disposed in the second rotating shaft groove 131 of the third side plate 13. The rotary shaft portion 21 of the pressure piece 20 is rotatable with respect to the groove wall of the first rotary shaft groove 111 and the groove wall of the second rotary shaft groove 131. Among them, groove walls of the first and second rotation shaft grooves 111 and 131 can restrict the rotation shaft portion 21 from sliding in the X-axis direction. In other embodiments, the rotating shaft portion 21 of the pressure piece 20 may be provided at other positions of the wire frame 10.

Referring to fig. 9 again, the wire pressing surface 221 of the wire pressing portion 22 is disposed toward the second side plate 12 of the wire frame 10. The first surface 231 of the biasing portion 23 is disposed toward the top plate 14 of the wire frame 10.

Referring to fig. 10, fig. 10 is a cross-sectional view of the wire frame 10 and the press block 20 shown in fig. 8 taken along line B-B. The second surface 232 of the urging portion 23 is provided toward the first side plate 11. The third surface 233 of the biasing portion 23 is provided toward the third side plate 13. The second surface 232 of the urging portion 23 may be provided at a distance from the first side plate 11. The third surface 233 of the urging portion 23 may be provided at a distance from the third side plate 13.

In other embodiments, the second surface 232 of the urging portion 23 may be provided in contact with the first side plate 11. The third surface 233 of the urging portion 23 may be provided in contact with the third side plate 13. Thus, the first side plate 11 and the third side plate 13 can limit the sliding of the pressure block 20 in the Y-axis direction. The connection between the pressing block 20 and the wire frame 10 is more stable. Further, the press block 20 can be prevented from coming off in the Z-axis direction by the frictional force between the urging portion 23 and the first and third side plates 11 and 13. In other embodiments, the press piece 20 is prevented from coming off in the Z-axis direction by setting the dimensional relationship between the press piece 20 and the wire frame 10.

In the present embodiment, since the first side plate 11 is inclined in the direction close to the third side plate 13, the second width L2 (see fig. 6) of the force applying portion 23 is smaller than the first width L1 (see fig. 5) of the wire pressing portion 22, so that the shape of the force applying portion 23 can be largely adapted to the shape of the space between the first side plate 11 and the third side plate 13, and the force applying portion 23 can be ensured to be disposed in the space between the first side plate 11 and the third side plate 13 and can largely occupy the space.

Referring to fig. 11 and 12, fig. 11 is a cross-sectional view of the terminal 100 shown in fig. 1 taken along line C-C. Fig. 12 is a sectional view of the connection terminal 100 shown in fig. 11 in another state. The fastening member 30 may be detachably coupled to the top plate 14 of the wire frame 10 by fastening engagement with the fastening hole 18. Thus, when the fastening member 30 passes through the fastening hole 18 of the wire frame 10, the fastening member 30 can abut against the first surface 231 of the biasing portion 23 of the pressing block 20 and press the first surface 231 to bias the biasing portion 23. The embodiment of the present invention will be described with reference to the fastener 30 shown in fig. 11 and 12, which is a screw. In each of fig. 11 and 12, the rotation shaft portion 21, the pressing line portion 22, and the urging portion 23 of the pressure block 20 are schematically illustrated by broken lines.

In other embodiments, when the fastening hole 18 is provided in the first side plate 11 or the third side plate 13, the fastener 30 may be detachably connected to the first side plate 11 or the third side plate 13. In other embodiments, when the wire frame 10 is not provided with the fastening hole 18, the fastening member 30 may also be directly fastened to the first side plate 11 and the third side plate 13. In other embodiments, the fastener 30 and the wire frame 10 may be non-detachably connected.

It will be appreciated that when the fastener 30 is tightened, the fastener 30 may be moved in the negative direction of the Z-axis and pass through the fastening hole 18, and the fastener 30 may press the force application portion 23 of the pressing block 20 to apply force to the force application portion 23. Thus, the fastener 30 can drive the pressing block 20 to rotate relative to the wire frame 10, and the pressing line part 22 of the pressing block 20 can rotate in the direction close to the second side plate 12. The distance between the pressing face 221 of the pressing portion 22 and the second side plate 12 decreases. When the fastener 30 is loosened, the fastener 30 can move in the positive direction of the Z-axis, the fastener 30 is separated from the force application portion 23 of the pressing piece 20, the pressing piece 20 can rotate relative to the wire frame 10, and the wire pressing portion 22 of the pressing piece 20 can rotate in the direction away from the second side plate 12. The pressing block 20 is returned to the original position.

In one embodiment, the mass 20 may be returned to its original position relatively quickly by positioning the center of gravity of the mass 20 adjacent to the first face 231 relative to the crimping face 221.

In other embodiments, when the fastener 30 is separated from the biasing portion 23 of the press piece 20, the press piece 20 may not rotate relative to the wire frame 10, that is, the state of the press piece 20 may not be changed.

The following describes a process for connecting the terminal 100 to a wire (not shown). It will be appreciated that the fastener 30 of the wire connection terminal 100 may be first separated from the wire frame 10 of the wire connection terminal 100. One end of the wire is then inserted through the wire connecting hole 17 of the wire connecting terminal 100 and positioned between the pressing block 20 and the second side plate 12 of the wire connecting terminal 100. The fastening member 30 of the connection terminal 100 is placed in the fastening hole 18 of the connection terminal 100, and the fastening member 30 is tightened so that the fastening member 30 presses the pressing piece 20 to drive the pressing piece 20 to rotate relative to the connection frame 10, and the wire pressing surface 221 of the pressing piece 20 presses the wire against the second side plate 12.

It can be understood that, compared to the scheme of fixing and connecting the wires by screws, in the present embodiment, one end of the wire is pressed against the second side plate 12 by the wire pressing surface 221 of the pressing block 20, the connection area between the wire and the connection terminal 100 is large, and the wire is not easily pulled out from the connection terminal 100. The connection terminal 100 of the present embodiment has a high connection capability. In addition, in the present embodiment, the crimping surface 221 is roughened (for example, at least a part of the crimping surface 221 is formed in a wave shape), so that the connection stability between the wire and the terminal 100 is further improved.

Referring to fig. 13 and 14, fig. 13 is a schematic structural diagram of an implementation manner of an electrical apparatus 1000 according to an embodiment of the present disclosure. FIG. 14 is a partial cross-sectional view of the electrical device 1000 shown in FIG. 13 at line D-D. The electrical device 1000 includes a terminal 100 and a housing 200. The electrical device 1000 may be a circuit breaker, a contactor, a relay, or the like.

In the present embodiment, the housing 200 is provided with a first through hole 201, a second through hole 202, a third through hole 203, and a fourth through hole 204, which are provided at intervals. The first through hole 201, the second through hole 202, the third through hole 203, and the fourth through hole 204 communicate with the inside of the housing 200.

In one embodiment, the housing 200 may include a tab (not shown). The first through hole 201, the second through hole 202, the third through hole 203, and the fourth through hole 204 may be disposed around the bump. The bumps can enhance the peripheral strength of the first through hole 201, the second through hole 202, the third through hole 203 and the fourth through hole 204, and prevent the housing 200 from being damaged.

In the present embodiment, the connection terminal 100 includes a first connection terminal 100a and a second connection terminal 100b. The first connection terminal 100a may be used for the connection terminal 100 of the positive electrode. The second connection terminal 100b may be used for the connection terminal 100 of the negative electrode. In other embodiments, the number of the connection terminals 100 of the electric device is not particularly limited.

Illustratively, the first side plate 11 of the first wire terminal 100a is disposed opposite the first side plate 11 of the second wire terminal 100b. It can be understood from fig. 4 and the related contents above that, compared to the rectangular first and second connection terminals 100a and 100b, the first connection terminal 100a of the present embodiment may save a portion of the volume of the first connection terminal 100a, that is, the volume of the side space 102 illustrated in fig. 4, by inclining the first side plate 11 of the first connection terminal 100a in a direction close to the third side plate 13 of the first connection terminal 100 a. Similarly, by tilting the first side plate 11 of the second connection terminal 100b in a direction to approach the third side plate 13 of the second connection terminal 100b, the second connection terminal 100b can save a part of the volume, that is, the volume of the side space 102 illustrated in fig. 4. In this way, when the first and second connection terminals 100a and 100b are disposed inside the housing 200, a portion of the second connection terminal 100b may be disposed in the side space 102 of the first connection terminal 100a, and a portion of the first connection terminal 100a may be disposed in the side space 102 of the second connection terminal 100b. In this way, the arrangement volumes of the first connection terminal 100a and the second connection terminal 100b are smaller, that is, the first connection terminal 100a and the second connection terminal 100b occupy a smaller internal space of the housing 200, and the utilization rate of the internal space of the housing 200 is higher.

In addition, by disposing the first side plate 11 of the first connection terminal 100a to oppose the first side plate 11 of the second connection terminal 100b, the position of the fastener 30 of the first connection terminal 100a may be disposed side by side with the position of the wiring hole 17 of the second connection terminal 100b, and the position of the wiring hole 17 of the first connection terminal 100a may be disposed side by side with the position of the fastener 30 of the second connection terminal 100b. At this time, the wire passing through the wire connection hole 17 of the first wire terminal 100a is distant from the wire passing through the wire connection hole 17 of the second wire terminal 100b, and the two wires are not easily short-circuited.

The housing 200 also illustratively includes a partition 205, the partition 205 being disposed between the first side plate 11 of the first wire terminal 100a and the first side plate 11 of the second wire terminal 100b. The spacer 205 may further prevent a wire passing through the wiring hole 17 of the first wiring terminal 100a from being shorted with a wire passing through the wiring hole 17 of the second wiring terminal 100b. It is understood that a portion of the partition 205 may be disposed in the side space 102 of the first connection terminal 100a and a portion of the partition 205 may be disposed in the side space 102 of the second connection terminal 100b.

Illustratively, a first stopper (not shown) is disposed on a side of the partition 205 facing the first connection terminal 100 a. The number of the first stoppers may be the same as the number of the first stopper holes 112 (see fig. 2) of the first connection terminals 100 a. When the first connection terminal 100a is assembled in the housing 200, the first stopper may be disposed in the first stopper hole 112 of the first side plate 11 of the first connection terminal 100 a. Thus, the connection between the first connection terminal 100a and the housing 200 is more stable.

For example, the frame of the housing 200 may also be provided with a second stopper (not shown). The number of the second stoppers may be the same as the number of the second stopper holes 132 (see fig. 3) of the first connection terminals 100 a. The second stopper may be disposed in the second stopper hole 132 of the third side plate 13 of the first connection terminal 100a when the first connection terminal 100a is assembled in the housing 200. Thus, the connection between the first connection terminal 100a and the housing 200 is more stable.

Referring to fig. 13 and 14 again, the first through hole 201 of the housing 200 may be disposed opposite to the fastening hole 18 of the first connection terminal 100 a. The third through hole 203 of the case 200 may be disposed opposite to the fastening hole 18 of the second connection terminal 100b. The second through hole 202 of the housing 200 may be disposed opposite to the wire connection hole 17 of the first wire connection terminal 100 a. The fourth through hole 204 of the housing 200 may be disposed opposite to the wire connection hole 17 of the second wire connection terminal 100b. In other embodiments, the positions of the first through hole 201, the second through hole 202, the third through hole 203, and the fourth through hole 204 of the case 200 and the fastening hole 18 and the wire connection hole 17 of the first wire terminal 100a and the fastening hole 18 and the wire connection hole 17 of the second wire terminal 100b are not particularly limited.

The present embodiment will be described by taking an assembly process of the first connection terminal 100a, a wire (not shown), and the housing 200 as an example. It is understood that the fastening member 30 of the first connection terminal 100a may be separated from the terminal frame 10 of the first connection terminal 100a first during the assembly of the first connection terminal 100a, the wire, and the housing 200. The wire frame 10 and the press block 20 of the first wire terminal 100a are fixed inside the housing 200. One end of the wire is inserted through the second through hole 202 of the housing 200 and the wire connection hole 17 of the first wire terminal 100a and positioned between the press piece 20 of the first wire terminal 100a and the second side plate 12 of the first wire terminal 100 a. The fastening member 30 of the first connection terminal 100a passes through the first through-hole 201 of the case 200 and is tightened in the fastening hole 18 of the first connection terminal 100a so that one end of the wire is pinched between the pressing block 20 and the second side plate 12.

The above description specifically describes a specific structure of the connection terminal 100. Another structure of the connection terminal 100 will be described in detail with reference to the accompanying drawings. The same technical contents as those of the terminal 100 described above, such as the arrangement of the pressing block 20 and the urging member 30, will not be described in detail. The following mainly describes the structure of the wire frame 10 of the connection terminal 100.

Referring to fig. 15, fig. 15 is a schematic structural diagram of a connection terminal 100 according to another embodiment of the present application. The wire frame 10 includes a first side plate 11, a second side plate 12 and a third side plate 13, the first side plate 11 and the third side plate 13 are connected by the second side plate 12, the first side plate 11 and the third side plate 13 are arranged oppositely, an angle between the first side plate 11 and the second side plate 12 is a first angle a, and the first angle a is an obtuse angle. At this time, the first side plate 11 is inclined in a direction away from the third side plate 13, and the wire frame 10 is substantially "trapezoidal".

It can be understood that, by inclining the first side plate 11 in the direction away from the third side plate 13, that is, the wiring frame 10 is substantially in a "trapezoid" shape, when the wiring terminal 100 is applied to the electrical apparatus 1000 (please refer to fig. 14), the first side plates 11 of the two wiring terminals 100 can be oppositely disposed, so that the two wiring terminals 100 can mutually utilize the space on one side of the first side plate 11, the arrangement volume of the two wiring terminals 100 is small, and the internal space occupied by the two wiring terminals 100 is small.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and the changes or substitutions should be covered within the scope of the present application; the embodiments and features of the embodiments of the present application may be combined with each other without conflict. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
