Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, and in particular to a shock-resistant shielded automotive connector structure. Background Technology

[0002] During operation, automobiles encounter complex and ever-changing road conditions, generating continuous and intense vibrations. Simultaneously, the numerous electronic devices within a vehicle create a highly complex electromagnetic environment. Under these circumstances, automotive connectors not only need to stably transmit electrical signals and data but also require excellent shock resistance and electromagnetic shielding performance.

[0003] Traditional automotive connectors have shortcomings in shock resistance. Their internal contacts and terminals are prone to loosening and displacement under prolonged vibration, leading to poor contact, affecting signal transmission stability, and in severe cases, even causing open circuits. Regarding shielding performance, the shielding layers of ordinary connectors are insufficient to effectively block interference from strong electromagnetic sources such as automotive engines and motors, causing signal distortion and delays, affecting the normal operation of automotive electronic systems. With the increasing intelligence and electrification of automobiles, the requirements for the shock resistance and shielding performance of connectors are becoming increasingly stringent. Therefore, this application proposes a stable, shock-resistant, shielded automotive connector structure. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a stable, shock-resistant, shielded automotive connector structure.

[0005] The technical solution of this utility model is: a shock-resistant shielded automotive connector structure, the connector including a first connector and a second connector, the connection part of the first connector and the second connector is respectively provided with a connection end and a contact end, and the connection end and the contact end are further provided with a first shielding layer and a second shielding layer for electromagnetic shielding;

[0006] A fastening connection part for auxiliary fastening connection between the first connector and the second connector is also provided. The fastening connection part includes a connecting arm connected to the upper surface of the second connector and a second hook head connected to one side of the first connector. A limit post and a spring are also elastically provided between the connecting arm and the second hook head.

[0007] Optionally, the fastening connection includes two sets of fixing seats that are fixedly connected to the upper surface of the second connector, and a fixing shaft is fixedly connected between the two sets of fixing seats. The connecting arm is sleeved and installed on the outer ring of the fixing shaft.

[0008] Optionally, torsion springs connected to two sets of fixed seats are respectively connected to both sides of the connecting arm.

[0009] Optionally, one end of the connecting arm is provided with a first hook head, and one end of the second hook head is provided with a hook portion. Both the first hook head and the hook portion are hook-shaped and are fitted together.

[0010] Optionally, a limiting groove is provided on the first hook head, and a locking hole is provided on the hook portion, and the limiting post is locked with the limiting groove.

[0011] Optionally, one end of the limiting post is also connected to a connecting rod, the spring is sleeved on the outer ring of the connecting rod, and one end of the spring is connected to the limiting post, while the other end is connected to one side of the mounting hole.

[0012] Optionally, a limiting plate larger than the diameter of the mounting hole is fixedly connected to one end of the connecting rod that passes through the mounting hole.

[0013] Optionally, a handle is also fixedly connected to the upper surface of the connecting arm.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model achieves the assembly and connection of the first connector and the second connector by setting a connection end and a contact end at the connection part of the first connector and the second connector, and utilizes the synergistic effect of the first shielding layer and the second shielding layer to form a multi-layer shielding structure, which can effectively block the interference of complex electromagnetic environment inside the car, ensure stable transmission of electrical signals, avoid signal distortion and delay, and improve the reliability of the car electronic system.

[0016] Furthermore, by using the elastically set limiting post and spring in the fastening connection part, in conjunction with the hook-shaped adapter and locking structure of the connecting arm and the second hook head, the connector can absorb and buffer external force when it is subjected to vibration, prevent the first connecting part and the second connecting part from loosening and shifting, ensure the stable connection of the internal contact parts, and extend the service life of the connector.

[0017] Furthermore, the two sets of fixed seats, fixed shafts, connecting arms and other components in the fastening connection part of this utility model cooperate with each other to form a solid auxiliary fastening structure, which not only enhances the connection strength between the first connector and the second connector, but also further optimizes the force distribution of the handle on the connecting arm, ensuring that the connector always maintains a tight connection in the bumpy environment of the car and reducing the risk of failure.

[0018] In summary, this utility model achieves efficient electromagnetic shielding by relying on the elastic components and hook-locking structure in the fastening connection part for shock resistance, and by using multiple components in the fastening connection part for secure connection, it comprehensively ensures stable signal transmission and reliable connection.

[0027] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments.

[0028] The components of the embodiments of this disclosure, which are typically described and shown in the accompanying drawings, can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of embodiments of this disclosure provided in the drawings is not intended to limit the scope of the claimed disclosure, but merely to illustrate selected embodiments of the disclosure.

[0029] Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

Therefore, they should not be construed as limitations on this disclosure.

[0031] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly.

[0032] Example 1

[0033] like Figures 1-4 As shown, the present invention proposes a shock-resistant shielded automotive connector structure. The connector includes a first connector 1 and a second connector 2. The connection parts of the first connector 1 and the second connector 2 are respectively provided with a connection end 11 and a contact end 21. The connection end 11 and the contact end 21 are further provided with a first shielding layer 22 and a second shielding layer 23 for electromagnetic shielding.

[0034] In this embodiment, the connection end 11 and contact end 21 of the connection between the first connector 1 and the second connector 2 are made of highly conductive metal material, such as aluminum alloy, to form an initial shielding layer that directly blocks some electromagnetic interference. The first shielding layer 22 and the second shielding layer 23 further enhance the shielding effect. The first shielding layer 22 is a metal braided mesh that reflects and absorbs electromagnetic signals through a dense metal wire structure. The second shielding layer 23 is a ferrite material with high magnetic permeability, which effectively suppresses low-frequency electromagnetic interference. The connection end 11, contact end 21, first shielding layer 22 and second shielding layer 23 are tightly fitted to form a continuous electromagnetic shielding space. When electromagnetic interference signals from inside the car propagate to the connector, an induced current is generated on the surface of these shielding components. The induced current forms a reverse magnetic field that cancels out the interference magnetic field, thereby preventing electromagnetic interference from entering the connector and ensuring stable transmission of electrical signals between the first connector 1 and the second connector 2, avoiding signal distortion or interruption due to electromagnetic interference.

[0035] Example 2

[0036] like Figures 1-4 As shown, based on Embodiment 1, a fastening connection part 3 for auxiliary fastening connection between the first connector 1 and the second connector 2 is also provided. The fastening connection part 3 includes two sets of fixing seats 31 fixedly connected to the upper surface of the second connector 2. A fixing shaft 32 is fixedly connected between the two sets of fixing seats 31. A connecting arm 34 is sleeved and installed on the outer ring of the fixing shaft 32. Torsion springs 33 connected to the two sets of fixing seats 31 are respectively connected to both sides of the connecting arm 34. A handle 35 is also fixedly connected to the upper surface of the connecting arm 34. The connecting arm 34 can be flipped along the fixing shaft 32 at one end by setting the handle 35.

[0037] like Figure 3 and Figure 4 As shown, the fastening connection part 3 includes a connecting arm 34 connected to the upper surface of the second connecting member 2 and a second hook head 36 connected to one side of the first connecting member 1. One end of the connecting arm 34 is provided with a first hook head 341, and one end of the second hook head 36 is provided with a hook portion 361. Both the first hook head 341 and the hook portion 361 are hook-shaped and are fitted together. A limit post 37 and a spring 310 are also elastically provided between the connecting arm 34 and the second hook head 36. A limit groove 342 is provided on a hook head 341, and a locking hole 362 is provided on the hook part 361. A limit plate 39 larger than the diameter of the locking hole 362 is fixedly connected to one end of the connecting rod 38 that passes through the locking hole 362. A limit post 37 is locked with the limit groove 342. One end of the limit post 37 is also connected to the connecting rod 38. A spring 310 is sleeved on the outer ring of the connecting rod 38, and one end of the spring 310 is connected to the limit post 37, and the other end is connected to one side of the locking hole 362.

[0038] In this embodiment, when it is necessary to connect the first connector 1 and the second connector 2, the two sets of fixed seats 31 fixedly connected to the upper surface of the second connector 2 in the fastening connection part 3 and the fixed shaft 32 between them provide basic support for the entire structure. The handle 35 serves as the operating handle. The connecting arm 34 is flipped along the fixed shaft 32. The hook-shaped first hook clamp 341 at one end of the connecting arm 34 and the hook-shaped hook part 361 at one end of the second hook clamp 36 are mutually adapted and clamped. This hook-shaped design increases the stability and reliability of the connection and prevents the connection from loosening due to vibration and other factors during the car's operation.

[0039] When the connector is subjected to vibration, the limiting post 37 and the spring 310 can absorb and buffer the external force. Specifically, during the vibration process, the external force first acts on the connecting arm 34 and the second hook clamp 36. Through the elastic deformation of the limiting post 37 and the spring 310, the vibration energy is converted into elastic potential energy, thereby reducing the vibration impact force transmitted to the connection part of the first connector 1 and the second connector 2. This effectively prevents the loosening and displacement between the first connector 1 and the second connector 2, ensures the stable connection of the internal contacts of the connector, extends the service life of the connector, and ensures that the connector can always maintain a tight connection in the complex environment of vehicle bumps, reducing the risk of failure.

[0040] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
