Description

Technical Field

[0001] The utility model relates to a vehicle device, in particular to an assembly structure of a vehicle device which is carried in a vehicle and used for capturing images and transmitting 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] In the patent documents related to FAKRA, for example, the prior art disclosed in Taiwan Publication No. M611190 aims to improve the reliability of the connection between two connection 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 a limited volume. 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, signal interference is likely to occur, affecting the quality of transmission, especially image signals, which may cause driving hazards for self-driving cars. Utility Model Content

[0004] The utility model aims to solve the problems in the above-mentioned prior art, and proposes a more novel assembly structure design of a vehicle device to achieve the practical requirements of the FAKRA connection mechanism with more streamlined components. The implementation method includes a first connection end, the first connection end has a main terminal, an insulating body partially covering the main terminal, and a shell, the shell has a chamber, the insulating body is assembled into the shell, and the main terminal is exposed in the chamber; and a second connection end, the second connection end has at least one contact terminal connected to a circuit board, an insulating seat body holding the contact terminal, and a mounting shell seat, wherein the mounting shell seat includes a base sleeved outside the insulating seat body, and the base is extended into the chamber of the shell to make the contact terminal contact with the main terminal, so that the signal transmitted by the circuit board communicates with the external device.

[0005] Thereby, when the first connection end is docked with the second connection end, the cavity of the shell provides a margin space for the mounting shell seat to allow the main terminal to be docked with the contact terminals even when the position of the component is offset. In other words, the FAKRA connection mechanism with a small volume requirement can also successfully complete the assembly work within a range of slight error in the size of each component, thereby improving the reliability of the final product, which is the main purpose of the present invention.

[0006] As other preferred solutions and purposes, the housing and the mounting housing are both made of metal to produce an electromagnetic shielding effect on the signals passing through the main terminal and the contact terminal to prevent external interference. In particular, the mounting housing also includes a seat plate extending outward from the base and abutting against the housing. In addition, a grounding area is pre-planned on the circuit board. When the contact terminal is welded to the circuit board, the bottom edge of the mounting housing contacts the grounding area. Thus, after the first connection end and the second connection end are assembled, the mounting housing contacts the housing with the seat plate, and noise can be transmitted to the grounding area of ​​the circuit board.

[0037] The following is a detailed description of an embodiment of the present invention, and the schematic diagrams of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions; the embodiments described with reference to the accompanying drawings are merely exemplary and are intended to explain one of the implementation methods of the present invention, rather than to limit the present invention.

[0038] 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 mainly includes a housing 2, a first connecting end 3, and a second connecting end 4. After the first connecting end 3 is assembled into the housing 2, the second connecting end 4 is connected to the first connecting end 3.

[0039] Preferably, the housing 2 has a neck 20 and an open accommodating space 21 , wherein the neck 20 and the accommodating space 21 are communicated with each other and with the outside.

[0040] The first connection end 3 includes a main terminal 30, an insulating body 31, and a shell 32, wherein the main terminal 30 is partially enclosed and fixed in the insulating body 31, and the insulating body 31 is engaged in the shell 32. Preferably, a plurality of barbs 310 are provided on the surface of the insulating body 31 to stably hold the insulating body 31 in the shell 32. The shell 32 has a hollow chamber 320. After the insulating body 31 is assembled into the shell 32, the main terminal 30 is exposed in the chamber 320. Preferably, the shell 32 is made of metal to produce an electromagnetic shielding effect on the signal passing through the main terminal 30 to prevent interference.

[0041] The shell 32 also has a mounting portion 321 that matches and assembles with the neck 20 of the shell 2. At least one first waterproof rubber strip 322 can be sleeved on the surface of the mounting portion 321. Preferably, the first waterproof rubber strip 322 just abuts against the inner surface of the neck 20 of the shell 2 to prevent water stains from entering the accommodating space 21. In addition, an outer baffle 323 protrudes from the bottom edge of the mounting portion 321. The outer baffle 323 is used to prevent the shell 32 from completely extending into the neck 20 of the shell 2. Preferably, at least one second waterproof rubber strip 324 is sleeved between the outer baffle 323 and the shell 2 to achieve a better waterproof effect.

[0042] The second connection end 4 includes at least one contact terminal 40 connected to a circuit board 5, an insulating seat 41 for holding the contact terminal 40, and a mounting shell 42 arranged outside the insulating seat 41; in actual application, a lens module (not shown) for capturing external images can be arranged on the circuit board 5, and the captured image signal is transmitted through the contact terminal 40. The insulating seat 41 is tightly fitted in the mounting shell 42 and fixed. Preferably, a plurality of longitudinal grooves 410 are provided on the surface of the insulating seat 41 to help assembly. At least one of the contact terminals 40 surrounds the main terminal 30. The contact terminal 40 has an elastic contact portion 400 protruding toward the main terminal 30, and is connected to the main terminal 30 through the contact portion 400; the mounting shell 42 is made of metal and serves as a signal shield for the contact terminals 40. It includes a hollow base 420 and a seat plate 421 extending outward from the base 420.

[0043] During assembly, the housing 32 of the first connection end 3 is first assembled into the neck 20 of the housing 2 with its mounting portion 321 and then the contact terminals 40 are fixed to the insulating base 41 and welded to a circuit board 5 , and the mounting housing 42 is sleeved on the outside of the insulating base 41 .

[0044] After the second connection end 4 is assembled, the mounting shell base 42 is extended into the cavity 320 of the shell 32 of the first connection end 3, and the contact terminals 40 are connected to the main terminals 30 of the first connection end 3 in a clamping manner, so that the electronic signals on the circuit board 5 can be transmitted through the contact terminals 40 and the main terminals 30; wherein, the seat plate 421 is pressed against the shell 32 of the first connection end 3 to play a limiting role, thereby preventing the mounting shell base 42 from excessively entering the shell 32.

[0045] Preferably, a grounding area 50 is pre-planned on the circuit board 5. When the contact terminals 40 are soldered to the circuit board 5, the bottom edge of the mounting shell 42 contacts the grounding area 50. Thus, after the first connection end 3 and the second connection end 4 are assembled, the mounting shell 42 contacts the housing 32 through the base plate 421, so that noise can be transmitted to the grounding area 50 of the circuit board 5.

[0046] Please also refer to Figure 2 When the first connection end 3 and the second connection end 4 are docked, the cavity 320 of the shell 32 provides a tolerant space for the mounting shell seat 42, allowing the main terminal 30 to be docked with the contact terminals 40 even when the component position is offset in the X-axis and Y-axis directions as shown in the figure. In other words, the FAKRA connection mechanism with a small volume requirement can also successfully complete the assembly work within a slight error range of the component size, thereby improving the reliability of the final product.

[0047] Since the number of components used in the present invention is much less than that of the prior art, the manufacturing cost can be greatly reduced, and the yield of the final product can be improved to reduce the occurrence of errors. It is truly a novel and progressive idea creation, and a patent application is filed in accordance with the law; it is stated in advance that the above-mentioned embodiments and drawings are not limited to the product form and style of the present invention, and any equivalent changes or modified designs made by ordinary technicians in the relevant technical field should still be deemed to be within the scope of the patent request of the present invention.
