Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a wire harness and an electrical system. Background Art

[0002] Currently, during the installation of wire harnesses, cable ties are usually used to tie the wire harnesses. However, when the cable ties are used to tie the wire harnesses, multiple wire harnesses are tied into a circular bundle, which causes heat to accumulate in the wire harnesses and prevents rapid heat dissipation. It also occupies space inside the box. At the same time, once tied, the cable ties cannot be disassembled and need to be disassembled with sharp tools, which can easily damage the insulation layer of the wire harness.

[0054] The utility model provides a cable tie 1 for binding a connecting line 2. The cable tie 1 includes a first body 10 and a second body 12. The first body 10 and the second body 12 are rotatably connected, and the first buckle 102 on the first body 10 and the second buckle 122 on the second body 12 can be engaged or disengaged, making the installation process of the cable tie 1 and the connecting line 2 more convenient and quick.

At the same time, multiple connecting wires 2 are arranged side by side in the cable trough 14, so that the multiple connecting wires 2 are arranged neatly, reducing the space occupied by the multiple connecting wires 2, and also increasing the heat dissipation area of ​​the multiple connecting wires 2, thereby reducing safety hazards. Figure 5 As shown, when the first clip 102 and the second clip 122 are separated, the connecting wire 2 in the cable trough 14 can be maintained without destructive treatment of the cable harness 1, so that the cable harness 1 can be reused. At the same time, it can also avoid damaging the insulation layer of the connecting wire 2 when the cable harness 1 is destructively treated, thereby improving the safety performance of the connecting wire 2 during production, installation and maintenance.

[0055] It is understood that the plurality of connecting wires 2 are arranged in a row from one end of the first body 10 to the other end of the first body 10. Optionally, when the plurality of connecting wires 2 are bound in the cable duct 14, the plurality of connecting wires 2 are arranged in a row. Of course, the plurality of connecting wires 2 can also be arranged in multiple rows.

[0056] Optionally, at least one of the first body 10 and the second body 12 includes a strip-shaped plate structure, so that after the first body 10 and the second body 12 are snapped together, the connecting line 2 can be pressed side by side. At the same time, the first body 10 and the second body 12 also have a certain width, increasing the restraint area and improving the fixing effect.

[0057] like Figure 3 As shown, in some embodiments, optionally, at least one of the first body 10 and the second body 12 includes a plurality of limiting grooves 124, and the plurality of limiting grooves 124 are distributed in sequence from one end to the other end of the first body 10 or the second body 12; wherein, the limiting grooves 124 are connected to the wiring groove 14, and any limiting groove 124 is used to clamp at least one connecting wire 2.

[0058] In this embodiment, at least one of the first body 10 and the second body 12 includes a plurality of limiting grooves 124, which are connected to the wire harness groove 14, and any limiting groove 124 is used to clamp at least one connecting wire 2, thereby fixing the connecting wire 2 in the limiting groove 124, avoiding the movement of the connecting wire 2, and making the multiple connecting wires 2 arranged more neatly. At the same time, the setting of the limiting groove 124 increases the space that the wire harness 1 can accommodate the connecting wire 2, realizes the bundling of thicker connecting wires 2, and can effectively limit the thicker connecting wires 2.

[0059] Optionally, when the limiting groove 124 is provided on the first body 10, the limiting groove 124 is provided on the side of the first body 10 facing the second body 12, and the plurality of limiting grooves 124 are distributed sequentially from one end of the first body 10 to the other end of the first body 10; when the limiting groove 124 is provided on the second body 12, the limiting groove 124 is provided on the side of the second body 12 facing the first body 10, and the plurality of limiting grooves 124 are distributed sequentially from one end of the second body 12 to the other end of the second body 12. When the limiting grooves 124 are provided on both the first body 10 and the second body 12, the limiting grooves 124 on the first body 10 are arranged opposite to the limiting grooves 124 on the second body 12, or the limiting grooves 124 on the first body 10 and the limiting grooves 124 on the second body 12 are staggered from one end of the first body 10 to the other end of the first body 10, thereby further increasing the gap between adjacent connecting wires 2 and improving the heat dissipation effect of the connecting wires 2.

[0060] In some embodiments, optionally, the inner wall surface of the limiting groove 124 is arc-shaped.

[0061] In this embodiment, the inner wall surface of the limiting groove 124 is arc-shaped to adapt to the shape of the connecting wire 2 and enhance the limiting effect on the connecting wire 2.

[0062] like Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, optionally, the second body 12 includes an arched portion 126 , which arches toward a side away from the first body 10 , and the arched portion 126 encloses a limiting groove 124 on a side wall facing the first body 10 .

[0063] In this embodiment, the second body 12 includes an arched portion 126, which arches toward the side away from the first body 10, and then forms a limiting groove 124 on the side of the arched portion 126 facing the first body 10, thereby reducing the manufacturing difficulty and reducing the material consumption while ensuring the structural strength.

[0064] Optionally, the portion of the first body 10 surrounding the limiting groove 124 is in a flat plate shape.

[0065] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the cable harness 1 further includes: a flexible portion 16 , and the flexible portion 16 is disposed in the limiting groove 124 .

[0066] In this embodiment, a flexible portion 16 is provided in the limiting groove 124, and the flexible portion 16 can produce deformation, so as to adjust the volume of the limiting groove 124 that can accommodate the connecting wire 2, thereby enabling the wire bundle 1 to bind both thinner connecting wires 2 and thicker connecting wires 2, thereby realizing the bundling of connecting wires 2 of different thicknesses and improving the versatility of the wire bundle 1.

[0067] like Figure 4 As shown, in some embodiments, optionally, along the depth direction of the limiting groove 124 , the flexible portion 16 fills at least a portion of the limiting groove 124 .

[0068] In this embodiment, the flexible portion 16 fills at least a portion of the limiting groove 124 in the depth direction, thereby enabling at least a portion of the limiting groove 124 in the depth direction to be adjusted, thereby increasing the wire diameter range of the connecting wire 2 that can be bound by the wire harness 1.

[0069] Optionally, the flexible portion 16 completely fills the limiting groove 124 along its depth direction, thereby achieving a blockage in the entire depth direction of the limiting groove 124, increasing the range of wire diameters that can be bounded by the connecting wire 2. Optionally, when binding a thinner connecting wire 2, the flexible portion 16 and the first body 10 together enclose the wire harness groove 14 to limit the position of the connecting wire 2. Furthermore, the shape of the flexible portion 16 is variable, thereby allowing the space in the limiting groove 124 to accommodate the connecting wire 2 to be adjusted throughout the entire depth range, and the deformation of the flexible portion 16 can also enhance the limiting effect on the connecting wire 2.

[0070] It can be understood that the depth direction of the limiting groove 124 is the direction in which the limiting groove 124 is recessed away from the first body 10 .

[0071] Optionally, the flexible portion 16 includes a rubber member, a silicone member, etc.

[0072] like Figure 3 、 Figure 4 and Figure 5As shown, in some embodiments, optionally, the cable tie 1 further includes: a connecting portion 18 provided on the first body 10 or the second body 12 , and the cable tie 1 is installed on the component to be installed through the connecting portion 18 .

[0073] In this embodiment, the cable tie 1 further includes a connecting portion 18, which is provided on the first body 10 or the second body 12 and is used to fix the cable tie 1 as a whole on the component to be installed to prevent the connecting wire 2 from falling off due to force or sliding back and forth, thereby damaging the insulation layer.

[0074] It is understandable that, when the connecting wire 2 is long, if the wire harness 1 is not fixed on the component to be installed after restraining the connecting wire 2, the connecting wire 2 may fall off due to the long span.

[0075] Optionally, the components to be installed include a circuit board 4 or a box 3 or a housing of the device.

[0076] In some embodiments, optionally, the connecting portion 18 includes a third buckle 180 , and the third buckle 180 is engaged with the component to be installed.

[0077] In this embodiment, the connecting portion 18 includes a third buckle 180 , which is engaged with the component to be installed, thereby simplifying the fixing steps of the cable harness 1 and improving installation efficiency.

[0078] In some embodiments, optionally, the connecting portion 18 is disposed on a side of the first body 10 facing away from the second body 12 , or on a side of the second body 12 facing away from the first body 10 .

[0079] In this embodiment, the connecting portion 18 is arranged on a side of the first body 10 facing away from the second body 12, or on a side of the second body 12 facing away from the first body 10, so that after the wire harness 1 is installed on the component to be installed, multiple connecting wires 2 can be arranged side by side on the component to be installed, reducing the space occupied by the multiple connecting wires 2.

[0080] In some embodiments, optionally, both the first body 10 and the second body 12 are plate-shaped structures.

[0081] In this embodiment, the first body 10 and the second body 12 are both plate-shaped structures, so that the first body 10 and the second body 12 have a certain length and width, and then the wiring groove 14 enclosed by the first body 10 and the second body 12 can fix multiple connecting wires 2 in a row, increasing the restraining area of ​​the connecting wires 2, avoiding the formation of marks on the surface of the connecting wires 2, and thus avoiding damage to the insulation layer on the surface of the connecting wires 2.

[0082] Optionally, the first body 10 and the second body 12 are both hard plate-shaped structures.

[0083] According to an embodiment of the present invention, an electrical system is provided, comprising: a plurality of connecting wires 2; and at least one wire harness 1 as provided above, wherein the plurality of connecting wires 2 are bound side by side in a wire harness groove 14 of the wire harness 1.

[0084] The electrical system provided by the present invention includes the wire harness 1 provided in any of the above embodiments, and thus has all the beneficial effects of the wire harness 1 .

[0085] Optionally, when there are multiple cable ties 1 , the cable ties 1 can bundle the connecting wires 2 at different positions, or bundle the connecting wires 2 at different positions.

[0086] like Figure 6 、 Figure 7 and Figure 8 As shown, in some embodiments, optionally, the electrical system further includes: a box 3; a circuit board 4, which is arranged in the box 3, the connecting wire 2 is electrically connected to the circuit board 4, and the connecting portion 18 of the wiring harness 1 is clamped with the circuit board 4 or the box 3.

[0087] In this embodiment, the electrical system further includes a housing 3 and a circuit board 4. The circuit board 4 is disposed within the housing 3 to implement electrical control of the electrical system. The connecting wires 2 are electrically connected to the circuit board 4. In addition to the fact that the cable harness 1 can bind multiple connecting wires 2 side by side, the cable harness 1 can also be secured to the circuit board 4 or the housing 3 via a connecting portion 18, thereby reducing drag on the connecting wires 2 and preventing the connecting wires 2 from detaching from the circuit board 4 or from sliding back and forth, which could damage the insulation layer of the connecting wires 2.

[0088] Optionally, at least one of the box body 3 and the circuit board 4 is provided with a mounting hole, and the mounting hole is engaged with the third buckle 180 of the cable harness 1 .

[0089] like Figure 7 and Figure 8 As shown, in some embodiments, optionally, the circuit board 4 includes a first side and a second side arranged opposite to each other, and the connecting wire 2 is electrically connected to the first side; wherein, at least one wire harness 1 is clamped on the first side, and / or the connecting wire 2 is wound from the first side to the second side of the circuit board 4, and at least one wire harness 1 is clamped on the second side.

[0090] In this embodiment, the circuit board 4 includes a first side and a second side that are oppositely disposed. One end of the connecting wire 2 is connected to the first side of the circuit board 4, and the other end of the connecting wire 2 can be connected to a component corresponding to the first side of the circuit board 4 or to a component corresponding to the second side of the circuit board 4. Figure 7 As shown, when the other end of the connecting wire 2 is connected to the component corresponding to the first side of the circuit board 4, the wire harness 1 can be clamped on the first side of the circuit board 4 to achieve the fixation of multiple connecting wires 2; Figure 8As shown, when the other end of the connecting wire 2 is connected to the component corresponding to the second side of the circuit board 4, the connecting wire 2 needs to be wrapped from the first side to the second side of the circuit board 4. At this time, the connecting wire 2 may contact the edge of the circuit board 4. By fixing the wire harness 1 on the second side of the circuit board 4, the situation in which the connecting wire 2 is damaged due to reciprocating friction with the edge of the circuit board 4 can be avoided.

[0091] In some embodiments, optionally, the electrical system includes any one of an inverter, a power distributor, and a battery pack.

[0092] In this embodiment, the electrical system includes any one of an inverter, a power distributor, and a battery pack.

[0093] Optionally, when the electrical system includes an inverter, the inverter includes a household storage inverter all-in-one machine.

[0094] In specific applications, the material of the wire tie bridge (e.g., the wire harness 1) proposed in this application is friendly to the outer insulation layer of the bound wire harness (e.g., the connecting wire 2), the cross-section of the wire tie structure is wide and the stress-bearing surface is large, the bound wire harness is evenly distributed on a horizontal plane without stacking, the buckle fixing form is firm, and it is easy and convenient to disassemble and maintain the wire harness. For some wire harnesses with long spans that cannot be fixed, it is inevitable to be stressed during equipment transportation and handling. The wire tie bridge is firmly fixed to the box 3, the shell, and the PCB (Printed Circuit Board) through the buckles on the back of the wire tie bridge (e.g., the third buckle 180), so that the wire harness has a fixed point, which can prevent the connector from falling off due to stress. When the wire tie bridge is fixed under the PCB board, the wire harness can be restrained to prevent the wire harness from sliding back and forth, and the sharp edge of the PCB board can be prevented from cutting the outer insulation of the wire harness surface. At the same time, the cable tying bridge has also been innovative in structure. The external circular limiting structure (such as the arched portion 126) can effectively limit the thicker power lines. The structure can be processed according to the wire diameter of the power lines. The internal flexible limiting structure (such as the flexible portion 16) can constrain the communication wire harness with a thinner wire diameter, preventing the thinner communication wire harness from sliding into the external circular limiting structure, making the cable tying bridge have better versatility.

[0095] like Figure 1 and Figure 2 As shown, in the related art, the wire harness 2' is bundled with a traditional cable tie 1', and multiple wire harnesses 2' are bundled together, which is not conducive to heat dissipation and also takes up space, and there is no buckle to fix the wire harness 2'. Figure 6 As shown, when the wire harness is bound by the wire tying bridge proposed in this application, the bound wire harness is evenly distributed on a horizontal plane without accumulation, and the heat dissipation space is reasonably utilized. Holes can also be opened on the sheet metal, and the wire tying bridge can fix the wire harness on the sheet metal box 3 through buckles.

[0096] like Figure 7As shown, the wire bridge is fixed on the PCB board (for example, the first side of the circuit board 4). The original binding strap cannot be fixed, and the wire bridge is now used to provide a fixed point for the wire harness. For some wire harnesses with longer spans that cannot be fixed, the connector can be prevented from falling off due to force.

[0097] like Figure 8 As shown, the wire bridge is fixed under the PCB board (for example, the second side of the circuit board 4). The original binding strap cannot be fixed. The wire bridge is now used to provide a fixed point for the wire harness, which restrains the wire harness so that it does not slide back and forth, and prevents the sharp part of the PCB board from cutting the outer insulation of the wire harness surface.

[0098] During later maintenance, the cable tie bridge proposed in this application does not require cutting the cable tie like traditional cable ties. Instead, it only requires unfastening the buckles (e.g., the first buckle 102 and the second buckle 122). In addition, since the cable tie bridge proposed in this application has a wider cross-section, it is friendly to the outer insulation layer of the wiring harness and will not cause strangulation marks. The cable tie bridge proposed in this application can effectively solve problems and hidden dangers in the production, installation, and maintenance of wiring harnesses.

[0099] During the production process, first press the buckle of the wire tie bridge on the mounting hole on the corresponding box 3 according to the path of the wiring harness, then press one end of the buckle, open the wire tie bridge, buckle the wiring harness into it, and press the movable part of the buckle into the fixed part of the buckle; during the maintenance process, first press the buckle of the wire tie bridge, open the wire tie bridge, buckle the wire tie bridge after the wiring harness is maintained, and press the movable part of the buckle into the fixed part of the buckle.
