Description

Technical Field

[0001] The utility model relates to a shielding mechanism for a vehicle device. The vehicle device is mainly carried in a vehicle to capture images and transmit signals. Background Art

[0002] FAKRA (FAchKReis Automobile) is a common connection mechanism for automotive devices, mainly used for signal transmission of vehicle-mounted equipment. It must have the characteristics of small size, light weight, and the ability to ensure connection reliability under extreme conditions to meet practical needs.

[0003] Patent documents related to FAKRA, such as Taiwan Publication No. M611190, disclose prior art that aims to improve the reliability of the connection between two connecting ends. However, due to the excessive number of components used in the contents disclosed in these patents, the assembly is difficult and the manufacturing cost is too high under the condition of volume reduction. In addition, the displacement and angle deviation during assembly may affect the reliability of the final product. In addition, the connection mechanism usually transmits high-frequency signals. If there is no appropriate grounding or signal shielding design, it is easy to cause signal interference and affect the transmission quality, especially the image signal, which may cause driving danger to the self-driving car.

[0004] The existing FAKRA vehicle device shielding mechanism is a housing stamped from a metal sheet, and a floating metal sleeve is connected to the housing as a shield for the vehicle device to transmit external signals. However, the floating metal sleeve is small in size, and it is difficult to assemble and position it in the closed space of the housing. In addition, the mechanism grounded to the housing may be damaged due to errors during the assembly process, making it difficult to improve the proper manufacturing rate of the vehicle device. Furthermore, the metal sheet is easily broken when the housing is made through multiple processing stations, cutting, bending, etc., which may cast doubts on the overall effect of signal shielding. Utility Model Content

[0005] The purpose of the utility model is to propose a shielding mechanism for a vehicle device, which expands the shielding range of the vehicle device for signals with a simpler structural relationship, and is easy to assemble and improves the proper rate. Its implementation method includes a metal shell, the metal shell has a hollow part, a mounting hole connected to the hollow part, and at least one mounting groove, the mounting groove is adjacent to the mounting hole and has a channel interconnected with the mounting hole; a metal sleeve, the metal sleeve is inserted into the mounting hole; and at least one grounding terminal, the grounding terminal has a main body portion accommodated in the mounting groove, and an elastic arm extending from the main body portion toward the channel direction into the mounting hole and abutting against the metal sleeve, and the contact between the grounding terminal, the metal sleeve and the metal shell is used to achieve the purpose of expanding the shielding range of the signal and completing the grounding.

[0006] Other preferred schemes and purposes include: the two sides of the main body of the grounding terminal each extend toward the two opposite sides of the installation slot to form a positioning portion to facilitate installation and positioning; and at least one barb is provided on the side edge of the positioning portion to pierce the slot wall of the installation slot for interference fixation.

DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0015] Please also refer to Figures 1 to 4 As disclosed, the vehicle device 1 described in the utility model can be, but is not limited to, a vehicle-mounted camera device, which has at least a housing 2 and a connection terminal 10 for external signal communication. A shielding mechanism 3 is provided in the housing 2. The shielding mechanism 3 includes a metal shell 4, at least one grounding terminal 5, and a metal sleeve 6. After the grounding terminal 5 is assembled into the metal shell 4, it abuts against the metal sleeve 6 and is then assembled together in the housing 2.

[0016] The housing 2 has a neck 20 and an open accommodation space 21 , wherein the neck 20 and the accommodation space 21 are communicated with each other and with the outside.

[0017] The metal shell 4 can be accommodated in the accommodating space 21 of the shell 2. It is integrally formed and has a hollow portion 40 for accommodating the electronic components of the vehicle device 1, a mounting hole 41 connected to the hollow portion 40, and at least one mounting groove 42; wherein the mounting groove 42 is adjacent to the mounting hole 41 and has a channel 43 interconnected with the mounting hole 41. In the preferred embodiment disclosed in the utility model, there are two mounting grooves 42, 42a, which are respectively arranged on two opposite sides of the mounting hole 41.

[0018] The metal sleeve 6 is floated in the mounting hole 41 to serve as a shield for connecting the internal and external signals of the vehicle device 1. Preferably, one end of the metal sleeve 6 is connected to the ground terminal of the vehicle device 1. Since this is the same as the existing vehicle FAKRA connection mechanism, it will not be described in detail here.

[0019] The grounding terminal 5 has a main body 50 accommodated in the installation slot 42, and an elastic arm 51 extending from the main body 50 toward the channel 43 into the installation hole 41 and abutting against the metal sleeve 6, wherein two sides of the main body 50 each extend a positioning portion 52 in the two opposite sides of the installation slot 42 to facilitate the installation and positioning of the grounding terminal 5, and at least one barb 53 is provided on the side edge of the positioning portion 52 to pierce the slot wall of the installation slot 42 for fixing. Preferably, corresponding to the two installation slots 42, 42a, there are two sets of grounding terminals 5, 5a respectively assembled in the two installation slots 42, 42a.

[0020] During assembly, the ground terminal 5 is placed in the mounting groove 42 of the metal shell 4, and then the metal shell 4 is inserted into the accommodating space 21 of the housing 2, and the metal sleeve 6 is aligned with the mounting hole 41 of the metal shell 4 so that the elastic arm 51 of the ground terminal 5 abuts against the metal sleeve 6. It can be found in the process that even if there are slight dimensional errors in the manufacturing of each component, the design of the elastic arm 51 of the ground terminal 5 can improve the fault tolerance rate, and the contact between the metal sleeve 6 and the metal shell 4 can be completed, so that the shielding range of the vehicle device 1 can be expanded and the grounding can be completed, thereby improving the yield of the final product and reducing the occurrence of errors.

[0021] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model.
