Description
Technical Field
[0001] The utility model relates to the technical field of wire protection boxes, in particular to a wire protection box for an automobile engine wiring harness. Background Art
[0002] The engine is the most important part of an automobile. There are many wires connected to the engine. During the use of the engine, a large amount of heat will inevitably be generated. Therefore, a wire protection box is needed to protect the wires and prevent safety accidents caused by overheating of the wires. These wires are of different thicknesses. For some wires with a larger diameter, there are many branch wires on the wires. Due to their greater hardness compared to wires with a smaller size, the reaction force exerted on the wire protection box by the wire fixed on the wire protection box is greater. Therefore, it is very difficult to fix wires with a larger diameter on the wire protection box. In the prior art, the wires are usually fixed on the wire protection box by cable ties. However, the existing wire protection boxes have the following defects: First, due to the limiting grooves of the existing wire protection boxes themselves, the cable ties do not have a good fixing effect on the wiring harness; Second, using cable ties on the existing wire protection boxes takes up a lot of space, and the available space near the automobile engine is very limited, so the space utilization rate must be improved; Third, since the wire protection box needs to be fixed on the cylinder block of the engine, the connection between the wire protection box and the cylinder block not only continuously receives the high heat transmitted from the cylinder block but also bears the weight of the wiring harness. Therefore, the connection between the wire protection box and the cylinder block is prone to aging and breaking. Summary of the Invention
[0003] In order to solve the above problems, the utility model provides a wire protection box for an automobile engine wiring harness with a long service life, good fixing effect on the wiring harness, and capable of improving the space utilization rate. The technical solution of the utility model: A wire protection box for an automobile engine wiring harness, comprising a junction box body, a first mounting block connected to the junction box body, and a second mounting block connected to the junction box body. Mounting holes are provided on both the first mounting block and the second mounting block. A limiting groove for restricting the position of the wiring harness is provided on the junction box body. An inlet, a first outlet, and a plurality of second outlets are further provided on the junction box body. The widths of the first outlet and the inlet are greater than the width of the second outlet. The inlet and the first outlet are respectively used for the main wiring harness to enter and exit, and the second outlet is used for the branch wires on the wiring harness to exit. A plurality of cable tie holes are provided at the bottom of the limiting groove. Every two cable tie holes form a cable tie hole group. The width of the cable tie hole is greater than or equal to the width of the cable tie.
[0004] With the above technical solution, first, the main wire of the wire harness enters through the inlet, then the branch wires on the wire harness are respectively discharged through the second outlet, and finally the main wire exits through the first outlet. In this way, the overall position arrangement of the wire harness can be completed. Then, one end of the cable tie passes through one of the cable tie holes in the cable tie hole group and then passes back into the limit groove through another cable tie hole in the cable tie hole group, so that the cable tie wraps the wire harness. This can not only improve the fixing effect of the cable tie on the wire harness, but also reduce the space occupied by the cable tie, thereby improving the space utilization rate of the junction box body.
[0005] Further setting of the present utility model: A plurality of fixing grooves are provided on the inner wall of the limit groove. The fixing grooves are respectively located on both sides of the limit groove, and the width of the fixing groove is adapted to the width of the cable tie.
[0006] With the above technical solution, since the fixing grooves are respectively located on both sides of the limit groove and the width of the fixing groove is adapted to the width of the cable tie, the junction box body and the wire harness can be wrapped by the cable tie, and the cable tie passes through the fixing groove. In this way, compared with the traditional cable tie fixing method, it can also achieve a certain effect of saving space. At the same time, through the double fixing method, the fixing effect of the cable tie on the position of the wire harness can be further improved.
[0007] Further setting of the present utility model: The positions of the cable tie hole group correspond to the positions of the inlet, the first outlet, and the second outlet respectively.
[0008] With the above technical solution, since the positions of the cable tie hole group correspond to the positions of the inlet, the first outlet, and the second outlet respectively, the wire harness can be fixed in a segmented manner by the cable tie. Especially at the position of the branch wire of the wire harness, since the bending degree of the wire harness is the largest, the position of the wire harness at these positions is the most difficult to fix, and the reaction force of the wire harness on the junction box body is the strongest. Therefore, setting the cable tie hole group at these positions can further improve the fixing effect of the cable tie on the wire harness. Further setting of the present utility model: A plurality of reinforcing ribs are provided on both the first mounting block and the second mounting block, and the reinforcing ribs are evenly distributed around the central axis of the mounting hole. With the above technical solution, since a plurality of reinforcing ribs are provided on both the first mounting block and the second mounting block, the strength of the first mounting block and the second mounting block can be improved, and the phenomenon of fracture at the connection between the cylinder block and the junction box body can be avoided, thereby improving the service life of the junction box.

Detailed implementation mode
[0012] As Figure 1-2 shown, a wire protection box for an automotive engine harness includes a junction box body 1, a first mounting block 2 connected to the junction box body 1, and a second mounting block 3 connected to the junction box body 1. Mounting holes 4 are provided on both the first mounting block 2 and the second mounting block 3. A limiting groove 5 for restricting the position of the wire harness is provided on the junction box body 1. The junction box body 1 is further provided with an inlet port 6, a first outlet port 7, and a plurality of second outlet ports 8. The widths of the first outlet port 7 and the inlet port 6 are greater than the width of the second outlet port 8. The inlet port 6 and the first outlet port 7 are respectively used for the main wire harness to enter and exit, and the second outlet ports 8 are used for the branch wires on the wire harness to exit. A plurality of tie - strap holes 9 are provided at the bottom of the limiting groove 5, and every two tie - strap holes form a tie - strap hole group 10. The width of the tie - strap hole 9 is greater than or equal to the width of the tie - strap.
[0013] First, the main wire of the wire harness enters through the inlet port 6, then the branch wires on the wire harness are respectively discharged through the second outlet ports 8, and finally the main wire exits through the first outlet port 7. In this way, the overall layout of the wire harness can be completed. Then, one end of the tie - strap passes through one of the tie - strap holes 9 in the tie - strap hole group 10 and then passes back into the limiting groove 5 through another tie - strap hole 9 in the tie - strap hole group 10, so that the tie - strap wraps the wire harness. This can not only improve the fixing effect of the tie - strap on the wire harness, but also reduce the space occupied by the tie - strap, thereby improving the space utilization rate of the junction box body 1.
[0014] A plurality of fixed grooves 11 are provided on the inner wall of the limiting groove 5. The fixed grooves 11 are respectively located on both sides of the limiting groove 5, and the width of the fixed groove 11 is adapted to the width of the tie - strap.
[0015] Since the fixed grooves 11 are respectively located on both sides of the limiting groove 5 and the width of the fixed groove 11 is adapted to the width of the tie - strap, the junction box body 1 and the wire harness can be wrapped by the tie - strap and the tie - strap passes through the fixed grooves 11. Compared with the traditional tie - strap fixing method, this can also achieve a certain effect of saving space. At the same time, through the double - fixing method, the fixing effect of the tie - strap on the position of the wire harness can be further improved.
[0016] The positions of the cable tie hole groups 10 respectively correspond to the positions of the inlet port 6, the first outlet port 7, and the second outlet port 8.
[0017] Since the positions of the cable tie hole groups 10 respectively correspond to the positions of the inlet port 6, the first outlet port 7, and the second outlet port 8, the cable tie can be used to fix the wire harness in a segmented manner. Especially at the position of the branch wire of the wire harness, since the bending degree of the wire harness is the largest, the position of the wire harness at these positions is the most difficult to fix, and the reaction force of the wire harness on the junction box body 1 is the strongest. Therefore, setting the cable tie hole groups 10 at these positions can further improve the fixing effect of the cable tie on the wire harness. A plurality of reinforcing ribs 12 are provided on both the first mounting block 2 and the second mounting block 3, and the reinforcing ribs 12 are uniformly distributed around the central axis of the mounting hole 4 in the axial direction.
[0018] Since a plurality of reinforcing ribs 12 are provided on both the first mounting block 2 and the second mounting block 3, the strength of the first mounting block 2 and the second mounting block 3 can be improved, and the phenomenon of fracture at the connection between the cylinder block and the junction box body 1 can be avoided, thereby improving the service life of the junction box.
