Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, specifically a Fakra connector. Background Technology

[0002] With the rapid development of automotive electronic systems, FAKRA connectors, as crucial components for high-frequency signal transmission in vehicles, are receiving increasing attention for their performance and reliability. In practical applications, traditional connectors face numerous technical challenges in reflow soldering processes, high-frequency signal shielding, vibration resistance, and assembly efficiency.

[0003] 1. In the reflow soldering process, due to the high soldering temperature, the electrical terminals of traditional connectors are prone to loosening or displacement due to thermal expansion and contraction or external forces. This instability may lead to soldering defects, such as poor solder joints or cold solder joints, thereby affecting the reliability of the connector.

[0004] 2. The driving environment of a vehicle involves complex vibrations and impacts. Traditional connectors, lacking sufficient support structures, are prone to problems such as loose internal terminals or poor contact. This not only affects the stability of signal transmission but may also lead to a decline in the long-term reliability of the equipment.

[0005] 3. Various sources of electromagnetic interference exist within automobiles, such as the engine and wireless communication modules. This interference can easily lead to distortion or leakage of high-frequency signals. Traditional connectors often lack sufficient shielding integrity in their design, making it difficult to meet the signal transmission requirements in complex electromagnetic environments.

[0006] 4. Traditional connectors have a complex structure, requiring high precision during assembly, which increases the complexity of the production line. Furthermore, repair and replacement are inconvenient during use, increasing maintenance costs.

[0007] 5. During reflow soldering, the high temperature environment can easily cause the electrical terminals to shift or loosen. Traditional connectors lack additional support design, making it difficult to guarantee the quality of the solder joints. Utility Model Content

[0008] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] A FAKRA connector includes an electrical terminal, a housing, a shielding substrate, and an insulating substrate. One end of the insulating substrate has an elastic retaining portion, and one part of the electrical terminal is disposed within the insulating substrate and the other part is snapped into the elastic retaining portion.

[0011] One end of the shielding substrate has a shielding fixing slot that matches the elastic retaining part, and the shielding fixing slot is connected to the other end of the shielding substrate to form a shielding opening. One end of the electrical terminal is installed at the shielding opening through the shielding substrate, and the other end is snapped into the shielding fixing slot through the elastic retaining part.

[0012] The shielding port is covered by the outer shell, and a plug-in position is formed between them.

[0013] Preferably, the electrical terminals are in the form of a line or an L-shape.

[0014] Preferably, the insulating substrate has a straight or L-shaped structure.

[0015] Preferably, the shielding substrate has a straight or L-shaped structure.

[0016] Preferably, the shielding substrate is made of an alloy material.

[0017] Preferably, the outer casing is further provided with at least one snap-fit ​​block.

[0020] Preferably, at least one welded positioning post is formed on the outer side of the shielding fixing slot.

[0021] Preferably, the electrical terminal is a signal terminal.

[0022] In summary, the technical effects and advantages of this utility model are as follows:

[0023] 1. The electrical terminals in this design are doubly secured by the elastic retaining portion within the insulating substrate and the shielding fixing groove in the shielding substrate. This prevents the terminals from loosening or shifting due to thermal expansion and contraction or external interference during the high-temperature reflow soldering process, thus ensuring precise terminal positioning and reliable solder joints. This improves soldering quality and reduces the risk of incomplete soldering and cold solder joints.

[0024] 2. One end of the shielding substrate of this utility model forms a shielding fixing groove, which closely cooperates with the elastic holding part of the insulating substrate to achieve stable support for the electrical terminals, thereby absorbing vibration and impact forces. In the complex driving environment of automobiles, it can effectively improve the shock resistance of the connector and ensure the long-term stability of signal transmission.

[0025] 3. The shielding port of this solution is fixed by injection molding with the outer shell, which not only prevents the influence of external electromagnetic interference (EMI) on the signal, but also effectively prevents the leakage of high-frequency signals, thereby improving the stability of signal transmission and electromagnetic compatibility performance.

[0026] 4. The electrical terminals of this utility model achieve modular assembly through the elastic holding part and the shielding fixing slot of the shielding substrate, which makes the installation of the terminals faster and more efficient, reduces the operational complexity of the production line, and facilitates subsequent maintenance and replacement, further reducing production and use costs.

[0027] 5. The elastic retaining part of this solution can provide additional support during reflow soldering, ensuring that the terminals will not loosen or shift due to temperature changes or operation during the soldering process, thereby ensuring the quality of the solder joint and enhancing the long-term stability of the terminals.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figures 1-8 As shown, a FAKRA connector includes an electrical terminal 1, a housing 2, a shielding substrate 3, and an insulating substrate 4. One end of the insulating substrate 4 has an elastic retaining portion 41. One part of the electrical terminal 1 is disposed inside the insulating substrate 4, and the other part is snapped into the elastic retaining portion 41. One end of the shielding substrate 3 has a shielding fixing groove 31 that matches the elastic retaining portion 41. The shielding fixing groove 31 is connected to a shielding opening 32 formed at the other end of the shielding substrate 3. One end of the electrical terminal 1 is installed at the shielding opening 32 through the shielding substrate 3, and the other end is snapped into the shielding fixing groove 31 through the elastic retaining portion 41. The housing 2 is fitted over the shielding opening 32, and a plug-in position S is formed between the housing and the housing. In this design, the electrical terminal 1 is doubly secured by the elastic retaining part 41 within the insulating substrate 4 and the shielding fixing groove 31 of the shielding substrate 3. This prevents the terminal from loosening or shifting due to thermal expansion and contraction or external interference during the high-temperature reflow soldering process, thus ensuring precise terminal positioning and the reliability of the solder joint. This improves soldering quality and reduces the risk of incomplete soldering and cold soldering. One end of the shielding substrate 3 forms a shielding fixing groove 31, which fits tightly with the elastic retaining part 41 of the insulating substrate 4, providing stable support for the electrical terminal 1. This absorbs vibration and impact, effectively improving the connector's shock resistance in the complex driving environment of automobiles and ensuring long-term stable signal transmission. The design of the shielding opening 32 being injection molded and fixed to the outer shell 2 not only prevents the influence of external electromagnetic interference (EMI) on the signal but also effectively prevents high-frequency signal leakage, improving the stability of signal transmission and electromagnetic compatibility performance. The electrical terminal 1 is modularly assembled via the elastic retaining part 41 and the shielding fixing slot 31 of the shielding substrate 3. This makes terminal installation faster and more efficient, reducing the operational complexity of the production line. Simultaneously, the modular design facilitates subsequent maintenance and replacement, further reducing production and usage costs. The elastic retaining part 41 provides additional support during reflow soldering, ensuring that the terminal does not loosen or shift due to temperature changes or operation during soldering, thereby guaranteeing solder joint quality and enhancing the long-term stability of the terminal. Specifically, the electrical terminal 1 is a signal terminal.

[0040] Preferably, the electrical terminal 1 is a straight line or an L-shaped structure. A straight line electrical terminal 1 (not shown) is suitable for linear signal transmission, with a simple path that effectively reduces signal reflection and loss, thereby improving the transmission efficiency of high-frequency signals. An L-shaped electrical terminal 1 can adapt to space-constrained installation requirements, optimizing the wiring path through a reversal design while maintaining signal integrity and stability, making it suitable for complex equipment layout scenarios.

[0041] Preferably, the insulating substrate 4 is a straight or L-shaped structure. A straight (not shown) insulating substrate 4 has a simple design, can stably fix the position of electrical terminals in straight wiring scenarios, avoids assembly errors caused by structural complexity, and is suitable for devices with relatively wide spaces. An L-shaped insulating substrate 4 can be used with L-shaped electrical terminals, optimizing space utilization to meet the installation requirements of narrow environments, while providing reliable support and insulation protection for the terminals, preventing signal interference and short-circuit risks.

[0042] Preferably, the shielding substrate 3 is a straight or L-shaped structure. A straight-line shielding substrate 3 (not shown) ensures the integrity of the shielding layer through its linear design, reducing shielding breaks in the signal transmission path and thus improving electromagnetic compatibility performance. An L-shaped shielding substrate 3 can accommodate the layout requirements of L-shaped electrical terminals and the insulating substrate 4, providing effective shielding protection in complex installation scenarios. It also adapts to signal interfaces in different directions, further optimizing the overall layout flexibility and space utilization.

[0043] Preferably, the shielding substrate 3 is made of an alloy material, specifically a zinc alloy, which can significantly improve the shielding effect.

[0044] Preferably, the outer casing 2 is further provided with at least one snap-fit ​​block 21 for snap-fit ​​fixing during assembly with a mating connector (not shown).

[0045] Preferably, the outer shell 2 is further provided with at least one anti-misfit strip 22. This strip serves to prevent mis-insertion during assembly with the mating connector (not shown).

[0046] Preferably, the shielding fixing slot 31 has an L-shaped structure, which facilitates the soldering of the electrical terminal 1 to the PCB (not shown).

[0047] Preferably, at least one welding positioning post 33 is formed on the outer side of the shielding fixing slot 31. This facilitates the positioning of the electrical terminal 1 when welding to the PCB (not shown), achieving the functions of positioning and limiting.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
