Description

Technical Field

[0001] The utility model relates to an assembly structure of a vehicle device, which is carried in the vehicle and is 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 literature related to FAKRA, for example, the prior art disclosed in Taiwan Announcement No. M611190 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 final product's proper rate. In particular, in this prior art, a plurality of elastic conductive terminals are used to surround the circuit board connected to the vehicle-mounted device (such as a camera lens), and the signal is transmitted through contact with the central conductive component. Since this connection mechanism usually transmits high-frequency signals, when the vehicle passes through bumpy roads or potholes and generates continuous and large vibrations, it is easy to cause instantaneous poor contact and distort the signal, especially the image signal, which may cause driving risks for self-driving cars. Utility Model Content

[0004] The purpose of the utility model is to propose an assembly structure of a vehicle device, which can achieve the practical requirements of the FAKRA connection mechanism with more streamlined components, and can overcome the problem that the signal transmission quality of the connection mechanism is affected when the vehicle vibrates. Its 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 main terminal has a conductive part, and when the insulating body is assembled into the shell, the conductive part is exposed in the chamber; a second connection end, the second connection end has a contact terminal connected to a circuit board, an insulating seat body holding the contact terminal, and a mounting shell seat, the mounting shell seat is extended into the chamber and assembled with the shell of the first connection end; wherein the contact terminal has a conductive end electrically connected to the circuit board and an elastic contact end capable of axial movement, and when the mounting shell seat is extended into the chamber, the contact end is conductively connected to the conductive part of the main terminal.

[0005] At the same time, 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, allowing the main terminal to be docked with the contact terminal 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 errors in the dimensions of each component, thereby improving the proper rate of the final product; more particularly, the contact terminal can absorb the vibration of the vehicle when docking with the main terminal through the elastic contact terminal design, so that the conductive connection relationship between the main terminal and the contact terminal is maintained constant without interruption, thereby ensuring the quality of signal transmission, which is the main purpose of the utility model.

[0006] As another preferred solution and purpose, an inner baffle is provided in the cavity of the shell of the first connecting end, and the mounting shell of the second connecting end includes a base, on which at least one elastic hook is provided, and the base is extended into the cavity so that the hook is deformed by the inner baffle and finally buckled on the inner baffle to complete the convenient assembly of the first connecting end and the second connecting end.

[0007] As other preferred solutions and purposes, the shell also has an outer baffle plate protruding from it, and a buffer spring is provided between the outer baffle plate and the shell and sleeved outside the shell, so that the buffer spring applies pre-pressure to the shell to make the contact between the main terminal and the contact terminal more certain, thereby ensuring the quality of signal transmission.

[0008] Other preferred solutions and purposes include: the housing and the mounting base are both made of metal to shield the signals passing through the main terminals and the contact terminals from external interference.

[0009] As other preferred schemes and purposes, the vehicle device also includes a shell, which is sleeved after the first connection end and the second connection end are assembled, so as to protect the first and second connection ends from external force intervention and damage; because the connection between the first connection end and the second connection end is completed first and then assembled into the shell together during assembly, it is convenient to first detect whether the signal is conductive between the docking relationship of the first and second connection ends, so as to improve the yield of the final product and reduce the occurrence of errors.

DETAILED DESCRIPTION

[0018] 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 elements or elements 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.

[0019] Please also refer to Figures 1 to 4 As disclosed, the vehicle device 1 described in the utility model is, for example, but not limited to, a vehicle-mounted camera device, which mainly includes a housing 2, a first connection end 3, and a second connection end 4. In the order of assembly, the first connection end 3 and the second connection end 4 are connected to each other and then assembled together in the housing 2.

[0020] Preferably, the housing 2 has a neck 20 and an open accommodating space 21 , and the neck 20 and the accommodating space 21 are communicated with each other and with the outside.

[0021] 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 its two axial ends exposed from the insulating body 31 include a connecting portion 300 and a conducting portion 301, the connecting portion 300 is used to connect to an external circuit, and the conducting portion 301 is used to contact and conduct with the second connection end 4. Preferably, the conducting portion 301 has a flat contact surface 301a.

[0022] The insulating body 31 is engaged in the housing 32, and 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 housing 32. The housing 32 has a hollow chamber 320. After the insulating body 31 is assembled into the housing 32, the contact surface 301a of the conductive portion 301 of the main terminal 30 is exposed in the chamber 320. Preferably, the housing 32 is a metal housing to form a better electromagnetic shielding for the signal passing through the main terminal 30 to reduce the interference from external noise.

[0023] The shell 32 also has a mounting portion 321 that matches and assembles with the neck 20 of the shell 2. At least one waterproof rubber strip 322 is sleeved on the surface of the mounting portion 321. Preferably, the waterproof rubber strip 322 abuts against the inner surface of the neck 20 of the shell 2 to prevent water stains from entering the accommodating space 21. An outer baffle 323 is also protruded 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 and prevent it from slipping out. In addition, an inner baffle 324 is also provided in the chamber 320 to dock with the second connecting end 4 (detailed description later); preferably, a buffer spring 325 is also provided between the outer baffle 323 and the shell 2 and sleeved on the outside of the shell 32 to absorb shock and apply a pre-pressure to the shell 32.

[0024] The second connection end 4 includes a 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; preferably, a lens module (not shown) for capturing external images is arranged on the circuit board 5, and the captured image signal is transmitted through the contact terminal 40.

[0025] The contact terminal 40 has a conducting end 400 electrically connected to the circuit board 5 and a contact end 401 with elasticity. Preferably, the conducting end 400 is cylindrical and has an opening 402 to allow the contact end 401 to be placed therein and expose a contact portion 403. A spring 404 is provided inside the cylindrical conducting end 400 to support the axial movement of the contact end 401, and under normal circumstances, the contact portion 403 is maintained in a conductive state with the contact surface 301a of the main terminal 30.

[0026] The mounting housing 42 is made of metal and serves as a signal shield for the contact terminal 40 . The mounting housing 42 includes a hollow base 420 . The base 420 is provided with at least one elastic hook 421 for buckling against the inner baffle 324 of the housing 32 of the first connection end 3 .

[0027] During assembly, the conducting end 400 of the contact terminal 40 is fixed to the insulating seat 41 and welded to the circuit board 5, and then the mounting shell 42 is sleeved with the insulating seat 41. After the second connection end 4 is assembled, the mounting shell 42 is inserted into the chamber 320 of the shell 32 of the first connection end 3, and the elastic hook 421 on the base 420 is deformed when passing through the inner baffle 324 of the chamber 320, and can be buckled on the inner baffle 324 without falling outward, and at the same time, the contact portion 403 of the contact terminal 40 is connected to the contact surface 301a of the main terminal 30, so that the electronic signal on the circuit board 5 can be transmitted through the contact terminal 40 and the main terminal 30, and the first connection end 3 and the second connection end 4 are assembled and fixed in the neck 20 of the shell 2 with the mounting portion 321 of the shell 32 after assembly, so that they are protected by the shell 2 and will not be interfered by foreign objects.

[0028] With the above, please also refer to Figure 2 and Figure 5 When the first connection end 3 and the second connection end 4 are connected, the cavity 320 of the housing 32 provides a space for the mounting housing seat 42 to allow the main terminal 30 to be connected with the contact terminal 40 even when the position of the components is offset in the X, Y and Z axis directions shown in the figure. In other words, the FAKRA connection mechanism with a small volume requirement can also successfully complete the assembly work within the range of a slight error in the size of each component, thereby improving the reliability of the final product. In addition, the buffer spring 325 disposed at the first connection end 3 provides the main terminal The floating contact between the main terminal 30 and the contact terminal 40 can absorb the vibration generated by the connection mechanism when the vehicle is traveling on a bumpy road; in particular, the contact terminal 40 is designed with an elastic contact end 401, which can absorb the vibration of the vehicle when docking with the main terminal 30 so that the conductive relationship between the main terminal 30 and the contact terminal 40 remains constant without interruption, and the pre-pressure applied to the shell 32 by the buffer spring 325 makes the contact between the main terminal 30 and the contact terminal 40 more certain, thereby ensuring the quality of signal transmission.

[0029] 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. In particular, during assembly, the first connection terminal 3 and the second connection terminal 4 are connected first and then assembled into the housing 2, so that it is convenient to first detect whether the signal is conductive at the docking relationship between the first and second connection terminals 3 and 4, so as to improve the yield of the final product and reduce the occurrence of errors. This is truly an excellent and progressive utility model, and a patent application is filed in accordance with the law.
