[0033] Embodiment 1:

[0034] In order to solve the problems that the connector is fixed on the steering wheel 1 foam body, with unreliable fixation and easy generation of abnormal noises, this embodiment provides a connector fixing clip. The connector is snap-connected to the connector fixing clip 30 to ensure the connection reliability and stability of the connector.

[0035] In this embodiment, the connector fixing clip 30 is a plastic part as a whole, meeting the lightweight requirement and not causing excessive weight gain due to the addition of the connector; as Figure 3 and Figure 4 shown, the connector fixing clip 30 includes a fixing main body, a first limiting part 32, and a second limiting part 33. In the installed state, the fixing main body is horizontally arranged; the fixing main body is a plate part, and its shape is adjusted according to the installation space.

[0036] According to Figure 3 and Figure 4 the view directions shown, both the first limiting part 32 and the second limiting part 33 are arranged on the upper surface of the fixing main body. The two together realize the snap connection of the connector and play a role in limiting the connector in the Z direction. Specifically, the first limiting part 32 is arranged near one end of the fixing main body, the second limiting part 33 is arranged near the other end of the fixing main body, and the distance between the first limiting part 32 and the second limiting part 33 is determined according to the length of the male end of the connector. Moreover, there are two first limiting parts 32 and two second limiting parts 33 respectively. The two first limiting parts 32 are symmetrically arranged with respect to the fixing main body. Similarly, the two second limiting parts 33 are symmetrically arranged with respect to the fixing main body.

[0037] After the male end and female end of the connector are docked, they are snap-connected to the connector fixing clip 30. The first limiting part 32 and the second limiting part 33 play a role in limiting the combined connector in the X direction and Z direction. Among them, the length direction of the fixing main body is the X direction, and the vertical direction is the Z direction. In order to meet the Z-direction limiting requirement, Z-direction limiting protrusions are provided at the tops of the first limiting part 32 and the second limiting part 33, and the top surface of the connector is clamped by the Z-direction limiting protrusions.

[0038] As Figures 3 - 6As shown in the figure, on one side of the Z-direction limiting protrusion of the first limiting portion 32, there is an X-direction limiting protrusion. The X-direction limiting protrusion is located on the side of the first limiting portion 32 away from the second limiting portion 33. The X-direction limiting protrusion and the Z-direction limiting protrusion are connected to form an inverted L-shaped structure, so that a groove structure is formed inside the first limiting portion 32. This groove structure is used to block the end face of the male connector; among them, the contact surface of the X-direction limiting protrusion with the male connector is the positioning surface A, and the left end face of the male connector (taking the Figure 5 direction shown as a reference) is the positioning surface A''; the positioning surface A and the positioning surface A'' contact to form X-direction limiting, and the Z-direction limiting protrusion contacts the top surface of the male connector to form Z-direction limiting. Moreover, the two first limiting portions 32 cooperate to perform Y-direction limiting on the connector.

[0039] Since the top end of the second limiting portion 33 is also provided with a Z-direction limiting protrusion, the longitudinal section of the second limiting portion 33 is in an inverted L-shaped structure; the side surface of the second limiting portion 33 facing the first limiting portion 32 is the positioning surface B. As Figure 6 shown, a U-shaped groove structure is provided at the top of the male connector. The right end face of the U-shaped groove structure is the positioning surface B'', and the positioning surface B and the positioning surface B'' contact to form X-direction limiting on the right end of the connector. The two second limiting portions 33 cooperate to perform Y-direction limiting on the right end of the connector.

[0040] Therefore, the two first limiting portions 32 and the two second limiting portions 33 are used to simultaneously limit the X-direction, Y-direction, and Z-direction of the connector, ensuring the stability of the entire connector and making it not easy to loosen even under the action of vibration and impact.

[0041] As Figure 3 and Figure 4 shown, the fixing body is provided with a fixing hole 34, and the connection with the steering wheel skeleton 11 is realized by arranging a connecting piece in the fixing hole 34. In this embodiment, a convex platform structure is provided on the bottom surface of the fixing body, and the fixing hole 34 penetrates through the center of the convex platform structure, so that the convex platform structure forms a snap fit with the steering wheel skeleton 11, and then is fixed by the connecting piece to make the connection more firm and reliable.

[0042] Among them, as Figure 7 shown, the fixing hole 34 forms a counterbore in the convex platform structure, and the connecting piece is a screw 12. After assembly, the whole screw 12 is arranged in the fixing hole 34 to prevent the screw 12 from protruding from the surface of the fixing body and affecting the installation of the connector.

[0043] In this embodiment, the convex platform structure has two platforms, and gradually shrinks from the side close to the fixing body to the other side, which is convenient for forming a limiting fit with the steering wheel skeleton 11.

[0044] The bottom surface of the fixed body is also provided with a positioning protrusion 31, which is inserted and matched with the steering wheel skeleton 11 through the positioning protrusion 31. The positioning protrusion 31 can be a pin. The positioning protrusion 31 can play a positioning role with the steering wheel skeleton 11, facilitating the cooperation between the boss structure and the steering wheel skeleton 11 and ensuring the installation accuracy.

[0045] The connector fixing clip 30 of this embodiment realizes the precise positioning of the connector fixing clip 30 by setting the positioning protrusion 31; after the male end 21 of the wire harness connector and the female end 22 of the connector are plugged in, they are fixed to the connector fixing clip 30 through snap connection; the installation stability is ensured through the connection and snap connection cooperation, avoiding the problem of the connector coming out.

[0046] The connector fixing clip 30 of this embodiment can effectively fix the connector, and at the same time can match the connectors of the same model, and can be fixed at other positions, meeting the requirements of platformized connector layout, and avoiding the risk of the connector loosening due to unreliable fixing; since the connector is effectively restricted in the X, Y, and Z directions, no abnormal noise will occur.

[0047] Embodiment 2:

[0048] This embodiment provides a steering wheel, as Figure 1 and Figure 2 shown. The steering wheel 1 includes a steering wheel skeleton 11, a sub-part skeleton 10, a clock spring 20, etc. The clock spring 20 is installed on the sub-part skeleton 10, and a wire harness is led out from the inside of the clock spring 20. The wire harness is connected to the male end 21 of the connector, and the male end 21 of the connector is inserted and matched with the female end 22 of the connector to form a connector; the connector is snap-connected to the connector fixing clip 30 described in Embodiment 1. Among them, after the connector fixing clip 30 is fixed to the steering wheel skeleton 11 through the screw 12, the connector is then matched with the connector fixing clip 30.

[0049] As Figure 7 shown, the positioning protrusion 31 of the connector fixing clip 30 corresponds to the jack of the steering wheel skeleton 11 to achieve positioning. The positioning protrusion 31 and the boss structure are simultaneously inserted into the steering wheel skeleton 11 until the bottom surface of the fixed body is attached to the steering wheel skeleton 11; then the screw 12 is passed through the fixing hole 34 and connected to the steering wheel skeleton 11. As Figure 8 shown, the docked connector is engaged with the first limiting portion 32 and the second limiting portion 33 of the connector fixing clip 30 to realize the installation of the connector.

[0050] In this embodiment, since the connector fixing card 30 is designed with a boss structure having a fixing hole 34 and a positioning protrusion 31, effective positioning and limiting with the steering wheel skeleton 11 are formed; the male end 21 of the connector and the female end of the connector are snap-connected to the connector fixing card 30 after being plugged; the Z-direction limiting of the connector is achieved by the snap connection of the first limiting portion 32 and the second limiting portion 33 with the connector; at the same time, the two first limiting portions 32 and the two second limiting portions 33 achieve Y-direction limiting of the connector; the X-direction limiting of the connector is achieved by the cooperation of the positioning surface A” and the positioning surface B” on the connector with the corresponding positioning surface A and positioning surface B of the connector fixing card 30, so as to ensure that the connector is firmly fixed to the steering wheel 1.

[0051] For the same connector, the connector fixing card 30 can achieve platform sharing for different steering wheel 1 shapes and different positions of the steering wheel skeleton 11, and realize generalization application.

[0052] Embodiment 3:

[0053] This embodiment provides a vehicle equipped with the steering wheel 1 described in Embodiment 2.
