Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing devices, in particular to a right-angle bent wire harness fixing device for an automobile engine. Background Art

[0002] The engine is an important component in an automobile. In an automobile engine, there are many wire harnesses connected to other components. If the wire harnesses are allowed to be arranged randomly, it is very easy to cause safety accidents. Therefore, it is necessary to fix the positions of the wire harnesses. Since the space inside the vehicle is limited, it is necessary to arrange the wire harnesses as reasonably as possible to save space. For this purpose, some wire harnesses need to be bent at a certain arc, and even some wire harnesses may need to be bent into a right-angle bend. The existing wire harness fixing devices have the following problems when fixing the right-angle bend of the wire harness: First, one end of the wire harness is connected to a circuit board. The existing fixing devices can only be fixed on the wire harness, and cannot ensure the relative position stability between the fixing device and the circuit board while fixing the wire harness. Second, the existing wire harness fixing devices usually include two fixing shells, and the two fixing shells are snap-connected together. Since there are many on-site components during assembly, users need to find two matching fixing shells and install them together, which is very time-consuming and affects the operation of the staff. Third, since the two fixing shells in the existing fixing device are snap-connected, it is easy to have the problem of unstable installation. Once the two fixing shells are separated, it is easy to cause the wire harness to be scattered. Therefore, a new type of fixing device is needed. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a right-angle bent wire harness fixing device for an automobile engine with stable installation structure, capable of ensuring the stable position of the wire harness and convenient installation.

[0004] The technical solution of the utility model: A right-angle bent wire harness fixing device for an automobile engine, including a first fixing shell and a second fixing shell. The first fixing shell is provided with a first wire inlet and a first wire outlet. The second fixing shell is provided with a second wire inlet and a second wire outlet. The opening directions of the first wire inlet and the second wire inlet are respectively perpendicular to the opening directions of the first wire outlet and the second wire outlet. The first fixing shell is provided with a plurality of first clamping blocks, and the second fixing shell is provided with a plurality of first clamping grooves. The number of the first clamping blocks is the same as that of the first clamping grooves. When the first fixing shell and the second fixing shell are assembled together, the positions of the first clamping blocks respectively correspond to the positions of the first clamping grooves. The first clamping blocks can be clamped into the first clamping grooves. A plurality of first pressing blocks fixedly connected to the first fixing shell are further arranged on the first wire inlet. When the wire harness is installed between the first fixing shell and the second fixing shell, the circuit board connected to the wire harness will be pressed between the first pressing blocks and the second fixing shell.

[0005] With the above technical solution, first, place the wire harness between the first fixed housing and the second fixed housing. The wire harness enters through the first inlet and the second inlet, and then exits through the first inlet and the second inlet. At the same time, align the position of the circuit board between the first inlet and the second inlet. Then, respectively snap the first clamping blocks into the first clamping grooves to fix the first fixed housing and the second fixed housing together. The circuit board will be pressed between the first pressing block and the second fixed housing, thereby ensuring the relative position stability among the first fixed housing, the second fixed housing, and the circuit board, and further ensuring the position stability of the wire harness.

[0006] Further setting of the present utility model: A plurality of second pressing blocks fixedly connected to the first fixed housing are further provided on the first inlet. When the wire harness is installed between the first fixed housing and the second fixed housing, the wire harness will be pressed between the second pressing blocks and the second fixed housing.

[0007] With the above technical solution, when the first fixed housing and the second fixed housing are connected together, the wire harness will be pressed between the second pressing blocks and the second fixed housing. Since the wire harness will exert a rebound force on the first fixed housing and the second fixed housing when being pressed tightly, therefore, the second pressing blocks pressing the wire harness tightly will reduce the rebound force received by the first pressing block, thereby further ensuring that the first fixed housing and the second fixed housing can be stably connected to the circuit board, and further ensuring the relative position stability between the wire harness and the wire harness fixing device.

[0008] Further setting of the present utility model: A plurality of connecting ribs are provided between the first fixed housing and the second fixed housing, and the connecting ribs have a certain elasticity.

[0009] With the above technical solution, since a plurality of connecting ribs are provided between the first fixed housing and the second fixed housing, and the connecting ribs have a certain elasticity, therefore, when installing the first fixed housing and the second fixed housing, only need to align the positions of the wire harness with the first inlet and the first outlet respectively, and then flip the second fixed housing to press the wire harness between the first fixed housing and the second fixed housing, which can greatly improve the assembly efficiency.

[0010] Further setting of the present utility model: Second clamping blocks are provided on both the left and right sides of the first inlet, second clamping grooves are provided on both the left and right sides of the second inlet, the positions of the second clamping blocks and the second clamping grooves correspond to each other, and the second clamping blocks can be snapped into the second clamping grooves.

[0011] With the above technical solution, since the second clamping blocks are provided on both the left and right sides of the first wire inlet, and the second clamping grooves are provided on both the left and right sides of the second wire inlet, when the second clamping blocks are clamped into the second clamping grooves, the connection stability of the first fixing housing and the second fixing housing at the positions of the first wire inlet and the second wire inlet can be further improved, the rebounding force received by the first pressing block can be reduced, so as to further ensure that the first fixing housing and the second fixing housing can be stably connected to the circuit board, and further ensure the relative position stability between the wire harness and the wire harness fixing device.

Detailed Embodiment

[0015] As Figure 1-2 shown, a right-angle bend wire harness fixing device for an automobile engine includes a first fixing housing 1 and a second fixing housing 2. The first fixing housing 1 is provided with a first wire inlet 3 and a first wire outlet 4, and the second fixing housing 2 is provided with a second wire inlet 5 and a second wire outlet 6. The opening directions of the first wire inlet 3 and the second wire inlet 5 are perpendicular to the opening directions of the first wire outlet 4 and the second wire outlet 6 respectively. The first fixing housing 1 is provided with a plurality of first clamping blocks 7, and the second fixing housing 2 is provided with a plurality of first clamping grooves 8. The number of the first clamping blocks 7 is the same as that of the first clamping grooves 8, and when the first fixing housing 1 and the second fixing housing 2 are assembled together, the positions of the first clamping blocks 7 correspond to the positions of the first clamping grooves 8 respectively. The first clamping blocks 7 can be clamped into the first clamping grooves 8. A plurality of first pressing blocks 9 fixedly connected to the first fixing housing 1 are further provided on the first wire inlet 3. When the wire harness is installed between the first fixing housing 1 and the second fixing housing 2, the circuit board connected to the wire harness will be pressed between the first pressing blocks 9 and the second fixing housing 2.

[0016] First, place the wire harness between the first fixed housing 1 and the second fixed housing 2. Insert the wire harness through the first inlet 3 and the second inlet 5, and then let it out from the first inlet 3 and the second inlet 5. At the same time, align the position of the circuit board between the first inlet 3 and the second inlet 5. Then, respectively snap the first clamping blocks 7 into the first clamping grooves 8 to fix the first fixed housing 1 and the second fixed housing 2 together. The circuit board will be pressed tightly between the first pressing block 9 and the second fixed housing 2, thereby ensuring the relative position stability among the first fixed housing 1, the second fixed housing 2, and the circuit board, and further ensuring the position stability of the wire harness. There are also several second pressing blocks 10 fixedly connected to the first fixed housing 1 on the first inlet. When the wire harness is installed between the first fixed housing 1 and the second fixed housing 2, the wire harness will be pressed between the second pressing block 10 and the second fixed housing 2.

[0017] When the first fixed housing 1 and the second fixed housing 2 are connected together, the wire harness will be pressed between the second pressing block 10 and the second fixed housing 2. Since the wire harness will exert a rebound force on the first fixed housing 1 and the second fixed housing 2 when it is pressed tightly, therefore, pressing the wire harness by the second pressing block 10 will reduce the rebound force received by the first pressing block 9, thereby further ensuring that the first fixed housing 1 and the second fixed housing 2 can be stably connected to the circuit board, and further ensuring the relative position stability between the wire harness and the wire harness fixing device.

[0018] There are several connecting ribs 11 between the first fixed housing 1 and the second fixed housing 2, and the connecting ribs 11 have a certain elasticity.

[0019] Since there are several connecting ribs 11 between the first fixed housing 1 and the second fixed housing 2, and the connecting ribs 11 have a certain elasticity, therefore, when installing the first fixed housing 1 and the second fixed housing 2, only need to align the position of the wire harness with the first inlet and the first outlet respectively, and then flip the second fixed housing 2 to press the wire harness tightly between the first fixed housing 1 and the second fixed housing 2, which can greatly improve the assembly efficiency.

[0020] Second clamping blocks 12 are provided on both the left and right sides of the first inlet 3, and second clamping grooves 13 are provided on both the left and right sides of the second inlet 5. The positions of the second clamping blocks 12 and the second clamping grooves 13 correspond to each other, and the second clamping blocks 12 can be snapped into the second clamping grooves 13.

[0021] Since the second clamping blocks 12 are provided on both the left and right sides of the first inlet 3, and the second clamping grooves 13 are provided on both the left and right sides of the second inlet 5, when the second clamping blocks 12 are clamped into the second clamping grooves 13, the connection stability of the first fixed housing 1 and the second fixed housing 2 at the positions of the first inlet 3 and the second inlet 5 can be further improved, the rebounding force received by the first pressing block 9 can be reduced, so as to further ensure that the first fixed housing 1 and the second fixed housing 2 can be stably connected to the circuit board, and further ensure the relative position stability between the wire harness and the wire harness fixing device.
