DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] A wiring harness fixing structure of an embodiment of the utility model comprises a fixing card 1, a first limiting member 2 and a second limiting member 3, one end of the first limiting member 2 is connected to the fixing card 1, and the second limiting member 3 is connected to the end of the first limiting member 2 away from the fixing card 1; the fixing card 1 is used to be fixedly connected to an external device, the first limiting member 2 is used to fix the first wiring harness 5, and the second limiting member 3 is used to fix the second wiring harness 6, see Figure 1 .

[0032] In the present application, the wiring harness fixing structure includes a fixing card 1, a first stopper 2 and a second stopper 3. The fixing card 1 is fixedly installed in an external device. In the present embodiment, the external device is a gas water heater. One end of the first stopper 2 is connected to the fixing card 1, and the other end extends in a direction away from the fixing card 1. The second stopper 3 is connected to the end of the first stopper 2 away from the fixing card 1, so that the first stopper 2 and the second stopper 3 are simultaneously arranged on the fixing card 1. The first wire harness 5 is fixed by the first stopper 2, and the second wire harness 6 is fixed by the second stopper 3, so that multiple wire harnesses can be fixedly installed on the fixing card 1 at the same time, so that the fixed installation of multiple wire harnesses in the gas water heater is convenient and quick, which greatly reduces the difficulty of wiring and assembly, and saves space.

[0033] Furthermore, a third stopper 4 is provided on the fixing card 1. One end of the second stopper 3 is connected to the first stopper 2, and the other end extends in a direction away from the first stopper 2. The third stopper 4 is connected to the end of the second stopper 3 away from the first stopper 2. Figure 1 By fixing the first wiring harness 5 with the first stopper 2, fixing the second wiring harness 6 with the second stopper 3, and fixing the third wiring harness 7 with the third stopper 4, the area occupied by the various cables in the horizontal direction can be further reduced, thereby making the fixed installation of the various wiring harnesses convenient and quick, greatly reducing the difficulty of routing and assembly, and making the routing of the various wiring harnesses in the gas water heater more regular, saving space in the gas water heater.

[0034] In actual implementation, the first limiting member 2, the second limiting member 3 and the third limiting member 4 are all arranged on the front side of the fixing card 1, and the back side of the fixing card 1 is provided with a mounting groove 11, see Figure 1 and Figure 2 The fixing card 1 can be fixedly installed in the external device (ie, the gas water heater) through the installation slot 11, thereby realizing the fixed installation of various wiring harnesses in the gas water heater.

[0035] In this embodiment, the first limiting member 2 includes a first bending portion 21 connected to the fixing card 1, and a first limiting groove 22 formed between the first bending portion 21 and the fixing card 1, and the first limiting groove 22 is used to fix the first wiring harness 5. Figure 2 and Figure 3 In the present application, the first limiting member 2 includes a first bending portion 21 and a first limiting groove 22. One end of the first bending portion 21 is connected to the fixing card 1, and the other end is bent in a direction away from the fixing card 1, so that the first limiting groove 22 is formed between the first bending portion 21 and the fixing card 1. When the first wiring harness 5 is fixedly installed, the first wiring harness 5 is installed in the first limiting groove 22, so that the first limiting groove 22 limits the first wiring harness 5, thereby achieving fixed installation of the first wiring harness 5 on the fixing card 1.

[0036] Specifically, in actual implementation, the first bending portion 21 can be a first bending angle with one end connected to the fixing card 1 and the other end bent in a direction away from the fixing card 1. The first limiting groove 22 is a first U-shaped groove formed between the first bending angle and the fixing card 1. The first wiring harness 5 is limited by the first U-shaped groove, thereby achieving fixed installation of the first wiring harness 5 on the fixing card 1.

[0037] In this embodiment, the top of the first limiting groove 22 is provided with a first opening 221 for the first wiring harness 5 to enter, and the bottom of the first limiting groove 22 is provided with a first mating surface 222 that matches the outer surface of the first wiring harness 5. The width of the first opening 221 is less than or equal to the diameter of the first mating surface 222. Figure 3 A first opening 221 is provided at the top of the first limiting groove 22 formed between the first bending portion 21 and the fixing card 1, so that the first wiring harness 5 can be installed in the first limiting groove 22 through the first opening 221. A first mating surface 222 is provided at the bottom of the first limiting groove 22, and the first mating surface 222 is mated with the outer surface of the first wiring harness 5, so that the installation of the first wiring harness 5 in the first limiting groove 22 is more stable.

[0038] The width of the first opening 221 is set to be smaller than or equal to the diameter of the first mating surface 222, that is, the width of the first opening 221 is smaller than or equal to the diameter of the first wire harness 5. When the width of the first opening 221 is equal to the diameter of the first wire harness 5, the first wire harness 5 can enter the first limiting groove 22 through the first opening 221, and the first mating surface 222 at the bottom of the first limiting groove 22 is matched with the outer surface of the first wire harness 5, so as to limit the first wire harness 5 and realize the installation of the first wire harness 5 on the fixing card 1.

[0039] When the width of the first opening 221 is smaller than the diameter of the first wiring harness 5, when the first wiring harness 5 is fixedly installed, the first opening 221 must be opened first, and then the first wiring harness 5 enters the first limiting groove 22 through the first opening 221 and cooperates with the first mating surface 222 at the bottom of the first limiting groove 22, and then the first opening 221 is retracted to its original state. Since the width of the first opening 221 is smaller than the diameter of the first wiring harness 5 at this time, the first wiring harness 5 cannot freely enter and exit the first limiting groove 22 through the first opening 221, thereby making the installation of the first wiring harness 5 in the first limiting groove 22 more stable.

[0040] It is foreseeable that: in the present application, the first stopper 2 can be made of a material with a certain elasticity, such as plastic, so that the first opening 221 can be opened under the action of an external force, so that the first wire harness 5 can enter the first stopper groove 22 through the first opening 221. When the force applied to the first opening 221 is released, the first opening 221 can automatically retract to the original state through the elasticity of the first stopper 2 itself, thereby limiting the first wire harness 5 located in the first stopper groove 22.

[0041] In this embodiment, the second stopper 3 includes a second bent portion 31 connected to an end of the first stopper 2 away from the fixing card 1, and a second stopper groove 32 formed between the second bent portion 31 and the first stopper 2, and the second stopper groove 32 is used to fix the second wiring harness 6, see Figure 2 and Figure 3 In the present application, the second limiting member 3 includes a second bending portion 31 and a second limiting groove 32. One end of the second bending portion 31 is connected to the end of the first bending portion 21 away from the fixing card 1, and the other end is bent in a direction away from the first bending portion 21, so that a second limiting groove 32 is formed between the second bending portion 31 and the first bending portion 21. When the second wiring harness 6 is fixedly installed, the second wiring harness 6 is installed in the second limiting groove 32, so that the second limiting groove 32 limits the second wiring harness 6, thereby achieving fixed installation of the second wiring harness 6 on the fixing card 1.

[0042] Specifically, in actual implementation, the second bending portion 31 can be a second bending angle with one end connected to the end of the first bending angle away from the fixing card 1, and the other end bent in the direction away from the first bending angle. The second limiting groove 32 is a second U-shaped groove formed between the second bending angle and the first bending angle. The second wiring harness 6 is limited by the second U-shaped groove, thereby achieving fixed installation of the second wiring harness 6 on the fixing card 1.

[0043] In this embodiment, the top of the second limiting groove 32 is provided with a second mating surface 322 that matches the outer surface of the second wiring harness 6, and the bottom of the second limiting groove 32 is provided with a second opening 321 for the second wiring harness 6 to enter, and the width of the second opening 321 is less than or equal to the diameter of the second mating surface 322, see Figure 3 A second opening 321 is provided at the bottom of the second limiting groove 32 formed between the second bending portion 31 and the first bending portion 21, so that the second wire harness 6 can be installed in the second limiting groove 32 through the second opening 321. A second mating surface 322 is provided at the top of the second limiting groove 32, and the second mating surface 322 is mated with the outer surface of the second wire harness 6, so that the installation of the second wire harness 6 in the second limiting groove 32 is more stable.

[0044] The width of the second opening 321 is set to be smaller than or equal to the diameter of the second mating surface 322, that is, the width of the second opening 321 is smaller than or equal to the diameter of the second wire harness 6. When the width of the second opening 321 is equal to the diameter of the second wire harness 6, the second wire harness 6 can enter the second limiting groove 32 through the second opening 321, and the second mating surface 322 at the top of the second limiting groove 32 is matched with the outer surface of the second wire harness 6, so as to limit the second wire harness 6 and realize the installation of the second wire harness 6 on the fixing card 1.

[0045] When the width of the second opening 321 is smaller than the diameter of the second wiring harness 6, for fixed installation of the second wiring harness 6, the second opening 321 must be opened first, and then the second wiring harness 6 enters the second limiting groove 32 through the second opening 321, and cooperates with the second mating surface 322 at the bottom of the second limiting groove 32, and then the second opening 321 is retracted to its original state. Since the width of the second opening 321 is smaller than the diameter of the second wiring harness 6 at this time, the second wiring harness 6 cannot freely enter and exit the second limiting groove 32 through the second opening 321, thereby making the installation of the second wiring harness 6 in the second limiting groove 32 more stable.

[0046] It is foreseeable that: in the present application, the second stopper 3 can be made of a material with a certain elasticity, such as plastic, so that the second opening 321 can be opened under the action of an external force, so that the second wire harness 6 can enter the second stopper groove 32 through the second opening 321. When the force applied to the second opening 321 is released, the second opening 321 can automatically close to the original state through the elasticity of the second stopper 3 itself, thereby limiting the second wire harness 6 located in the second stopper groove 32.

[0047] In this embodiment, the third limiting member 4 includes a third bending portion 41 connected to an end of the second limiting member 3 away from the first limiting member 2, and a third limiting groove 42 formed between the third bending portion 41 and the second limiting member 3, and the third limiting groove 42 is used to fix the third wiring harness 7, see Figure 2 and Figure 3 In the present application, the third limiting member 4 includes a third bending portion 41 and a third limiting groove 42. One end of the third bending portion 41 is connected to the end of the second bending portion 31 away from the first bending portion 21, and the other end is bent in a direction away from the second bending portion 31, so that a third limiting groove 42 is formed between the third bending portion 41 and the second bending portion 31. When the third wiring harness 7 is fixedly installed, the third wiring harness 7 is installed in the third limiting groove 42, so that the third limiting groove 42 limits the third wiring harness 7, thereby achieving fixed installation of the third wiring harness 7 on the fixing card 1.

[0048] Specifically, in actual implementation, the third bending portion 41 can be a third bending angle with one end connected to one end of the second bending angle away from the first bending angle, and the other end bent in the direction away from the second bending angle. The third limiting groove 42 is a third U-shaped groove formed between the third bending angle and the second bending angle. The third wiring harness 7 is limited by the third U-shaped groove, thereby achieving fixed installation of the third wiring harness 7 on the fixing card 1.

[0049] In this embodiment, the top of the third limiting groove 42 is provided with a third opening 421 for the third wire harness 7 to enter, and the bottom of the third limiting groove 42 is provided with a third mating surface 422 mating with the outer surface of the third wire harness 7, and the width of the third opening 421 is less than or equal to the diameter of the third mating surface 422. The top of the third limiting groove 42 formed between the third bending portion 41 and the second bending portion 31 is provided with a third opening 421, so that the third wire harness 7 can be installed in the third limiting groove 42 through the third opening 421. The bottom of the third limiting groove 42 is provided with a third mating surface 422, and the third mating surface 422 is mated with the outer surface of the third wire harness 7, so that the installation of the third wire harness 7 in the third limiting groove 42 is more stable.

[0050] The width of the third opening 421 is set to be smaller than or equal to the diameter of the third mating surface 422, that is, the width of the third opening 421 is smaller than or equal to the diameter of the third wire harness 7. When the width of the third opening 421 is equal to the diameter of the third wire harness 7, the third wire harness 7 can enter the third limiting groove 42 through the third opening 421, and the third mating surface 422 at the bottom of the third limiting groove 42 cooperates with the outer surface of the third wire harness 7, thereby limiting the third wire harness 7 and realizing the installation of the third wire harness 7 on the fixing card 1.

[0051] When the width of the third opening 421 is smaller than the diameter of the third wiring harness 7, when the third wiring harness 7 is fixedly installed, the third opening 421 must be opened first, and then the third wiring harness 7 can enter the third limiting groove 42 through the third opening 421 and cooperate with the third matching surface 422 at the bottom of the third limiting groove 42, and then the third opening 421 is retracted to its original state. Since the width of the third opening 421 is smaller than the diameter of the third wiring harness 7 at this time, the third wiring harness 7 cannot freely enter and exit the third limiting groove 42 through the third opening 421, thereby making the installation of the third wiring harness 7 in the third limiting groove 42 more stable.

[0052] Since commonly used wiring harnesses are generally cylindrical, that is, the first wiring harness 5, the second wiring harness 6 and the third wiring harness 7 are cylindrical, in actual implementation, the first mating surface 222 can be an arc surface with a contour similar to the outer surface contour of the first wiring harness 5, so that the first mating surface 222 can better limit the first wiring harness 5; the second mating surface 322 can be an arc surface with a contour similar to the outer surface contour of the second wiring harness 6, so that the second mating surface 322 can better limit the second wiring harness 6; the third mating surface 422 can be an arc surface with a contour similar to the outer surface contour of the third wiring harness 7, so that the third mating surface 422 can better limit the third wiring harness 7.

[0053] Furthermore, since the various wiring harnesses installed in the gas water heater have different actual uses, the types and sizes of the wiring harnesses are also different. Therefore, in the present application, the first wiring harness 5, the second wiring harness 6 and the third wiring harness 7 can be wiring harnesses with different diameters, and the diameter of the first mating surface 222 and the width of the first opening 221 can be designed according to the diameter of the first wiring harness 5, the diameter of the second mating surface 322 and the width of the second opening 321 can be designed according to the diameter of the second wiring harness 6, and the diameter of the third mating surface 422 and the width of the third opening 421 can be designed according to the diameter of the third wiring harness 7, so that the present fixing structure can be suitable for the fixed installation of wiring harnesses of different types and sizes, thereby making the present fixing structure more applicable and more practical.

[0054] Furthermore, according to the above embodiment, the end of the first bending portion 21 away from the fixing card 1 is bent upward, so that the first opening 221 of the first limiting groove 22 faces upward, and the first limiting groove 22 is located at the bottom of the first bending portion 21. The second bending portion 31 is connected to the first bending portion 21 at the first opening 221 of the first limiting groove 22, and the end of the second bending portion 31 away from the first bending portion 21 is bent downward, so that the second opening 321 of the second limiting groove 32 faces downward, and the second limiting groove 32 is located at the top of the second bending portion 31, see Figure 3 Therefore, when the fixing card 1 is fixedly installed in the gas water heater, the height of the second limiting groove 32 in the vertical direction is greater than the height of the first limiting groove 22 in the vertical direction. At the same time, the distance between the first wiring harness 5 and the second wiring harness 6 in the horizontal direction is reduced by the retracted first opening 221, thereby reducing the area occupied by various cables in the horizontal direction and saving space for the gas water heater.

[0055] The third bending portion 41 is connected to the second bending portion 31 at the second opening 321 of the second limiting groove 32, and one end of the third bending portion 41 away from the second bending portion 31 is bent upward so that the third opening 421 of the third limiting groove 42 faces upward, and the third limiting groove 42 is located at the bottom of the third bending portion 41. Figure 3Therefore, when the fixing card 1 is fixedly installed in the gas water heater, the height of the third limiting groove 42 in the vertical direction is greater than the height of the first limiting groove 22 in the vertical direction, and less than the height of the second limiting groove 32 in the vertical direction. At the same time, the distance between the second wiring harness 6 and the third wiring harness 7 in the horizontal direction is reduced by the retracted second opening 321, thereby further reducing the area occupied by various cables in the horizontal direction and saving space in the gas water heater.

[0056] Furthermore, in the present application, the fixing card 1, the first stopper 2, the second stopper 3 and the third stopper 4 can adopt an integrated structure, so that the entire wiring harness fixing structure is made of a material with a certain elasticity such as plastic, so that the first wiring harness 5 can enter the first stopper groove 22 through the first opening 221, the second wiring harness 6 can enter the second stopper groove 32 through the second opening 321, and the third wiring harness 7 can enter the third stopper groove 42 through the third opening 421, and the stability of the wiring harness fixing structure can be improved. It can be foreseen that: in actual implementation, the wiring harness structure can also be provided with a fourth stopper, a fifth stopper, a sixth stopper, etc., for fixing more types of wiring harnesses, which can be determined according to actual production conditions.

[0057] In this embodiment, the first limiting member 2 also includes a first fixing hole 23 that connects the first limiting groove 22 with the outside world, the second limiting member 3 also includes a second fixing hole 33 that connects the second limiting groove 32 with the outside world, and the third limiting member 4 also includes a third fixing hole 43 that connects the third limiting groove 42 with the outside world. The first fixing hole 23, the second fixing hole 33 and the third fixing hole 43 are respectively used to bind the first wiring harness 5, the second wiring harness 6 and the third wiring harness 7. Figure 2 In the present application, the first limiting member 2 also includes a first fixing hole 23, and the first fixing hole 23 connects the two sides of the first limiting groove 22 with the outside world. Therefore, when the first wiring harness 5 is installed in the first limiting groove 22, the first wiring harness 5 can be tied to the bottom of the first bending portion 21 after the binding belt passes through the first fixing hole 23, so that the first wiring harness 5 is fixed in the first limiting groove 22 more stably.

[0058] Similarly, the second limiting member 3 is also provided with a second fixing hole 33, which connects the two sides of the second limiting groove 32 with the outside world. Therefore, when the second wiring harness 6 is installed in the second limiting groove 32, the second wiring harness 6 can be tied to the top of the second bending portion 31 after the binding tape passes through the second fixing hole 33, so that the second wiring harness 6 is fixed in the second limiting groove 32 more stably; the third limiting member also includes a third fixing hole 43, which connects the two sides of the third limiting groove 42 with the outside world. Therefore, when the third wiring harness 7 is installed in the third limiting groove 42, the third wiring harness 7 can be tied to the bottom of the third bending portion 41 after the binding tape passes through the third fixing hole 43, so that the third wiring harness 7 is fixed in the third limiting groove 42 more stably.

[0059] In this embodiment, the third stopper 4 further includes an anti-pressure tail hook 44 disposed at one end of the third bending portion 41 away from the second stopper 3, and the anti-pressure tail hook 44 is used to support the external device when the external device squeezes the third bending portion 41. In the present application, the third stopper 4 further includes an anti-pressure tail hook 44, which is disposed at one end of the third bending portion 41 away from the second bending portion 31, and the anti-pressure tail hook 44 extends horizontally for a distance and then bends downward.

[0060] Since there are many parts in the gas water heater, when the fixing card 1 is fixedly installed in the gas water heater, the first wire harness 5, the second wire harness 6 and the third wire harness 7 are fixedly installed on the fixing card 1. In actual use, the parts in the gas water heater may squeeze the third bending part 41 on the fixing card 1, which not only affects the use of this fixed structure, but also may cause damage to the wire harness, affecting the use of the wire harness. Therefore, in this application, an anti-pressure tail hook 44 is provided at one end of the third bending part 41 away from the second bending part 31. When the parts in the gas water heater squeeze the third bending part 41, the anti-pressure tail hook 44 supports the parts, thereby preventing the parts from excessively squeezing the third bending part 41, thereby improving the stability and reliability of this fixed structure.

[0061] This embodiment also provides a gas water heater, comprising the above-mentioned wiring harness fixing structure.
