Description

Technical Field

[0001] The utility model relates to an assembly structure of a vehicle device, which is arranged in the vehicle 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 literature related to FAKRA, a prior art disclosed aims to improve the reliability of the connection between two connecting ends. However, due to the excessive number of components used in the content disclosed in the prior art, it is difficult to assemble under the condition of volume reduction and the manufacturing cost is too high. 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 no appropriate grounding or signal shielding design is provided, signal interference is likely to affect the transmission quality, especially the image signal, which may cause driving hazards for self-driving cars. Utility Model Content

[0004] The purpose of the utility model is to propose a more novel "assembly structure of a vehicle device" design, which can achieve the practical requirements of the FAKRA connection mechanism with more streamlined components.

[0005] The implementation method of the utility model includes a first connection end, the first connection end has a main terminal, an insulating body partially covering the main terminal, and a shell, wherein the shell has a chamber with an arc-shaped longitudinal section, and the main terminal is exposed in the chamber when the insulating body is assembled into the shell; and a second connection end, the second connection end has at least one contact terminal connected to a circuit board, an insulating seat body for fixing the contact terminal, and a mounting shell seat, wherein one end of the mounting shell seat has a spherical surface, and the spherical surface has a through hole for the main terminal to enter, and when the mounting shell seat extends into the chamber of the shell, the contact terminal contacts the main terminal, so that the signal transmitted by the circuit board communicates with the external device.

[0006] Thereby, when the first connection end is docked with the second connection end, the cavity of the shell provides a space for the mounting shell seat to tolerate assembly position errors. In particular, the spherical surface of one end of the mounting shell seat allows the main terminal to be docked with the contact terminals without dead angles in the cavity at the top of the arc even if 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 errors in the dimensions of each component, thereby improving the reliability of the final product.

[0007] As other preferred solutions and purposes, the housing and the mounting shell are both made of metal to shield the signals passing through the main terminals and the contact terminals from external interference. In particular, a grounding area is pre-planned on the circuit board. When the contact terminals are welded to the circuit board, the bottom edge of the mounting shell contacts the grounding area, and the noise can be transmitted to the grounding area of ​​the circuit board.

[0008] As another preferred solution, the vehicle device further includes a housing having a neck and an open accommodating space, wherein the neck communicates with the accommodating space and is in communication with the outside.

[0009] As another preferred solution, the shell of the first connecting end has a mounting portion that matches and is assembled with the neck of the shell, and the shell also has an outer baffle protruding outwardly to abut against the neck.

[0010] As another preferred solution, the contact terminal has a plurality of elastic contact portions surrounding the main terminal, each of which has an elastic contact portion protruding toward the main terminal.

[0011] As another preferred solution, at least one waterproof rubber strip is sleeved on the surface of the mounting portion, and the waterproof rubber strip abuts against the inner surface of the neck.

[0012] As another preferred solution, a plurality of longitudinal grooves are provided on the surface of the insulating base to help the insulating base to be assembled into the mounting housing. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0024] 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.

[0025] 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 outer 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, and the longitudinal section of the top of the chamber 320 is an arc 320a.

[0026] The shell 32 also has a mounting portion 321 that matches and is assembled with the neck 20 of the shell 2. At least one waterproof rubber strip 322 can be sleeved on the surface of the mounting portion 321. Preferably, the 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 fully extending into the neck 20 of the shell 2.

[0027] The second connection end 4 includes at least one contact terminal 40 connected to a circuit board 5, an insulating base 41 for holding the contact terminal 40, and a mounting shell 42 arranged outside the insulating base 41; in actual application, a lens module (not shown) for capturing external images can be configured on the circuit board 5, and the captured image signal can be transmitted through the contact terminal 40. Among them, the insulating seat body 41 is tightly fitted in the mounting shell seat 42 and fixed. Preferably, a plurality of longitudinal grooves 410 are also provided on the surface of the insulating seat body 41 to assist in assembly. The contact terminal 40 surrounds the main terminal 30 and 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 seat 42 is made of metal and serves as a signal shield passing through the contact terminals 40. One end of the mounting shell seat 42 has a spherical surface 42a, and the spherical surface 42a has a through hole 420 for the main terminal 30 to enter.

[0028] 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 .

[0029] After the second connection end 4 is assembled, the mounting shell 42 is extended into the chamber 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.

[0030] 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 housing 42 contacts the grounding area 50 , thereby transmitting noise signals to the grounding area 50 of the circuit board 5 .

[0031] With the above, please also refer to Figure 2 When the first connection end 3 is docked with the second connection end 4, the cavity 320 of the shell 32 provides a space for the mounting shell seat 42 to tolerate assembly position errors. In particular, the spherical surface 42a at one end of the mounting shell seat 42 allows the main terminal 30 to be docked with the contact terminals 40 without dead angles in the cavity 320 at the top of the arc 320a when component position offsets occur in the X-axis, Y-axis and Z-axis directions as shown in the figure. In other words, the FAKRA connection mechanism that requires a small volume can also successfully complete the assembly work within a range of slight errors in the dimensions of each component, thereby improving the reliability of the final product.

[0032] 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. The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by technicians in this technical field on the basis of the present invention are all within the protection scope of the present invention.
