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 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 volume reduction. In addition, the displacement and angle deviation during assembly may affect the final product's reliability. In addition, in this prior art, a plurality of elastic conductive terminals 47 are used to surround the circuit board 1 connected to the vehicle-mounted device (such as a camera lens), and the signal is transmitted through contact with the central conductive component 43. 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 utility model aims to provide an assembly structure of a vehicle device, which can achieve the practical requirements of a 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; a second connection end, the second connection end has a contact terminal connected to a circuit board, a terminal insulating seat body holding the contact terminal, and a mounting shell seat, the contact terminal has a contact portion, the mounting shell seat includes a base sleeved outside the terminal insulating seat body, the base is assembled with the shell of the first connection end, and the contact portion of the contact terminal is connected to the main terminal; wherein, the main terminal has a conducting end, the conducting end is exposed in the chamber when the insulating body is assembled into the shell, the conducting end is outer-mounted with a conducting spring, one end of the conducting spring abuts against the contact portion of the contact terminal, so that the signal of the contact terminal is interconnected with the main terminal via the conducting spring.

[0005] Thus, when the first connection end is connected 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 connected 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; more particularly, a conductive spring is connected to the outer shell of the main terminal, so that the signal of the contact terminal can communicate with the main terminal through the conductive spring, so that the vibration of the vehicle can be absorbed so that the conductive relationship between the main terminal and the contact terminal is maintained constant without interference, so as to ensure 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 chamber of the shell, and at least one elastic hook is provided on the base, so that the base is extended into the chamber so that the hook is deformed by the inner baffle and finally buckled on the inner baffle to complete the assembly of the first connecting end and the second connecting end.

[0007] As another preferred solution and purpose, the contact terminal includes a conducting portion connected to the circuit board and a contact portion in contact with the main terminal, wherein the contact portion is cylindrical and has an opening to allow the conducting end of the main terminal and the conducting spring sleeved on the conducting end to extend into and connect with the contact portion, so as to protect the conducting spring from falling out and being interfered with or damaged by external forces. Moreover, the contact portion with a cylindrical design provides a wider contact surface with no dead angles to connect with the conducting spring to maintain the quality of signal transmission.

[0008] As another preferred scheme and purpose, the two axial ends of the main terminal exposed from the insulating body include a connecting end and a conducting end, the conducting end is used for contacting and conducting with the second connecting end, and the conducting spring is sleeved on the periphery of the conducting end and contacts with the conducting end; in particular, a protrusion is provided on the main terminal and connected to the conducting end, one end of the conducting spring abuts against the protrusion, and the surface of the protrusion is a conical surface that gradually shrinks toward the conducting spring. The design of the conical surface makes the contact surface between the conducting spring and the conducting end wider, and even if the conducting spring is twisted or deformed during operation, it will not affect the contact quality between the conducting spring and the conducting end.

[0009] As another preferred solution and purpose, it also includes: an outer baffle plate protrudes from the outside of the shell, a seat plate extends outward from the bottom edge of the base, and a spring sleeve is abutted between the outer baffle plate and the seat plate and is mounted outside the shell; the elastic effect of the spring configured between the first connecting mechanism and the second connecting mechanism provides a floating contact between the main terminal and the contact terminals, which can absorb the vibration generated by the connecting mechanism when the vehicle is traveling on a bumpy road, thereby ensuring that the quality of the transmitted signal is not affected and is not interrupted.

[0010] 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.

[0011] 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 of 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 of the docking relationship between the first and second connection ends is conductive, so as to improve the yield of the final product and reduce the occurrence of errors.

[0012] As other preferred solutions and purposes, the housing has a neck and an open accommodating space, the neck and the accommodating space are interconnected and communicated with the outside; the housing of the first connecting end has a mounting portion that is matched and assembled with the neck. 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] Please also refer to Figures 1 to 4 As shown, 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 connecting end 3, and a second connecting end 4. In the order of assembly, the first connecting end 3 and the second connecting end 4 are connected to each other and then assembled together in the housing 2.

[0025] 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.

[0026] The first connection end 3 mainly 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 to the insulating body 31 include a connection end 300 and a conducting end 301, wherein the connection end 300 is used to connect with an external circuit, and the conducting end 301 is used to contact and conduct with the second connection end 4, wherein a conducting spring 302 is sleeved on the periphery of the conducting end 301 and is connected to the conducting end 301. Preferably, the main terminal 30 has a protrusion 30a connected to the conducting end 301, and one end of the conducting spring 302 abuts against the protrusion 30a. Preferably, the surface of the protrusion 30a is a conical surface that gradually shrinks toward the conducting spring 302. The design of the conical surface makes the contact surface between the conducting spring 302 and the conducting end 301 wider, and even if the conducting spring 302 is twisted or deformed during operation, it will not affect the contact quality between the conducting spring 302 and the conducting end 301.

[0027] The insulating body 31 is engaged in the housing 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 housing 32. The housing 32 has a hollow chamber 320. After the insulating body 31 is assembled into the housing 32, the conducting end 301 of the main terminal 30 is exposed in the chamber 320. Preferably, the housing 32 is a metal housing to form an electromagnetic shield for the signal passing through the main terminal 30 to prevent it from external interference.

[0028] The housing 32 also has a mounting portion 321 that matches and assembles with the neck 20 of the housing 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 housing 2 to prevent water stains from entering the accommodating space 21. An outer baffle 323 is protruded from the bottom edge of the mounting portion 321. The outer baffle 323 is used to prevent the housing 32 from fully extending into the neck 20 of the housing 2 and preventing it from slipping out. An inner baffle 324 is provided in the chamber 320 to dock with the second connecting end 4 (to be described in detail later).

[0029] The second connection end 4 includes a contact terminal 40 connected to a circuit board 5, a terminal insulating seat body 41 holding the contact terminal 40, a mounting shell seat 42 arranged outside the terminal insulating seat body 41 and interferingly fixed therewith, and a spring 43; 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. The surface of the terminal insulating seat body 41 is provided with a plurality of interference members 410 interferingly fixed with the mounting shell seat 42. Among them, the contact terminal 40 has a conducting portion 400 connected to the circuit board 5 and a contact portion 401 in contact with the main terminal 30. Preferably, the contact portion 401 is cylindrical and has an opening 402 to allow the conducting end 301 of the main terminal 30 and the conducting spring 302 sleeved outside the conducting end 301 to extend into and connect with the contact portion 401, so as to protect the conducting spring 302 from falling out and being interfered or damaged by external forces. Moreover, the contact portion 401 with a cylindrical design provides a wider and non-dead angle contact surface to connect with the conducting spring 302 to maintain the quality of signal transmission.

[0030] The mounting shell 42 is made of metal and serves as a signal shield for the contact terminal 40. It includes a hollow base 420 and a base plate 421 extending outward from the bottom edge of the base 420. The base 420 is provided with a plurality of elastic hooks 422. The spring 43 is sleeved outside the shell 32 and abuts against the base plate 421 and the outer baffle 323.

[0031] During assembly, the contact terminal 40 is fixed to the terminal insulating seat 41 and welded to the circuit board 5, and then the mounting shell 42 is sleeved on the terminal insulating seat 41 for linkage, and the spring 43 is sleeved on the base 420. 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 422 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 400 of the contact terminal 40 is connected to the main terminal 30 of the first connection end 3, so that the electronic signal on the circuit board 5 can be transmitted through the contact terminal 40 and the main terminal 30, and after 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, so that they are protected by the shell 2 and will not be interfered by foreign objects.

[0032] With the above, please refer to Figure 2 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-axis and Y-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 a range of slight error in the size of each component, thereby improving the reliability of the final product; in particular, the spring 43 disposed between the first connection mechanism 3 and the second connection mechanism 4 can play a role in The elastic effect of the connecting mechanism further provides a floating contact between the main terminal 30 and the contact terminal 40, which can absorb the vibration in the Z-axis direction shown in the figure when the vehicle is traveling on a bumpy road, thereby ensuring that the quality of the transmitted signal is not affected and is not interrupted; in particular, through the design of the conductive spring 302, the signal of the contact terminal 40 can be interconnected with the main terminal 30 via the conductive spring 302, and the vibration of the vehicle can be absorbed so that the conductive relationship between the main terminal 30 and the contact terminal 40 is maintained constant without interference, thereby ensuring the quality of signal transmission.

[0033] 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 end 3 and the second connection end 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 ends 3 and 4, so as to improve the yield of the final product and reduce the occurrence of errors.

[0034] 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. The protection scope of the present utility model shall be subject to the claims.
