Over the next five years, the industry will shift its focus from simply expanding scale to strengthening its capabilities, with a primary development direction being the promotion of energy-saving vehicles, including new energy vehicles. However, due to the unique operating conditions and limited installation space of automobiles, automotive electrical connectors require compact structures, small sizes, ease of operation, strong resistance to these special operating conditions, reliable and safe electrical connections, and adequate shielding. Because new energy vehicle connectors are small and require consideration of numerous shielding factors, there are currently no mature shielded connectors for small cables used in new energy vehicles in China.

[0003] Furthermore, the high-voltage connectors used in new energy electric vehicles currently have various structural shapes, and in most cases, the cables can rotate or move axially within the product during assembly. To address this issue, various structures and accessories with anti-rotation and anti-reverse functions have been designed, thus increasing the number of assembly parts and assembly steps. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a plastic connector with a shielding structure, suitable for 35mm... 2 ~70mm 2 Both shielded and unshielded cables are available. Furthermore, the connector's housing is made of high-quality plastic material, offering excellent insulation and corrosion resistance, effectively ensuring the safe operation of the circuit. Simultaneously, its compact design, small size, and light weight make it easy to carry and install, reducing the difficulty of installation and significantly improving work efficiency.

[0005] The present invention solves the above problems through the following technical solution:

[0006] A plastic connector including a shielding structure includes: a housing assembly through which a cable is disposed;

[0007] The bottom of the housing assembly is equipped with a rubber-coated sealing ring that mates with the mounting panel of the customer's enclosure;

[0008] The housing assembly has an internal step. One end of the housing assembly that mates with the mounting panel is provided with a waveform shielding spring, an outer shielding ring, and an inner shielding ring. The outer and inner shielding rings abut against the internal step. The waveform shielding spring is inserted into the outer shielding ring and contacts the mounting panel through the waveform shielding spring.

[0009] A tail cap is attached to the other end of the housing assembly.

[0010] As a further improvement, the rubber-coated sealing ring is provided with three lips.

[0011] As a further improvement, a latch is formed on the outer side of the housing assembly away from the rubber sealing ring, and the latch is engaged with the latch of the tail cover.

[0012] As a further improvement, the housing assembly is also provided with a foolproof structure to engage with the slot of the tail cap.

[0013] As a further improvement, a gasket, a sealing body, and a wire clamp are sequentially provided at the other end of the housing assembly. The gasket abuts against the internal step, and the two ends of the sealing body abut against the gasket and the wire clamp, respectively.

[0014] As a further improvement, when the cable is a shielded cable, the shielding layer of the shielded cable is sandwiched and crimped between the outer shielding ring and the inner shielding ring.

[0015] As a further improvement, the housing assembly is made of plastic material.

[0016] As a further improvement, the flanged plane of the outer shielding ring is riveted and fixed to the wave shielding spring.

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.

[0030] Example:

[0031] Combined with appendix Figure 1-5As shown, a plastic connector with a shielding structure includes: a waveform shielding spring 1, a shielding outer ring 2, a shielding inner ring 3, a housing assembly 4, a gasket 5, a wire seal 6, a wire clamp 7, a tail cap 8, and a cable 9. The cable passes through the housing assembly 4. The bottom of the housing assembly 4 has a rubber-coated sealing ring 41 that mates with the mounting panel 10 of the customer's enclosure. The housing assembly 4 has an internal step. At one end of the housing assembly 4 that mates with the mounting panel 10, the waveform shielding spring 1, the shielding outer ring 2, and the shielding inner ring 3 are located. The shielding outer ring 2 and the shielding inner ring 3 abut against the internal step. The waveform shielding spring 1 is inserted into the shielding outer ring 2 and contacts the mounting panel 10 through the waveform shielding spring 1. The other end of the housing assembly 4 has a tail cap 8 that snaps onto it. This connector is compatible with shielded and unshielded cables ranging from 35mm² to 70mm². Furthermore, the housing of this connector assembly is made of high-quality plastic material, possessing excellent insulation performance and corrosion resistance, effectively ensuring the safe operation of the circuit. Meanwhile, its compact structure, small size, and light weight make it easy to carry and install, reducing the difficulty of installation and operation and greatly improving work efficiency.

[0032] The bottom of the housing assembly 4 is provided with a rubber-coated sealing ring 41, see Figure 1 As shown; the rubber-coated sealing ring 41 is designed with three lips for waterproof sealing when the connector assembly 11 is installed onto the mounting panel 10 of the customer's enclosure. Figure 2 As shown. A latching platform 42 is formed on the outer side of the housing assembly 4 away from the rubber sealing ring 41. The latching platform 42 is engaged with the latching opening of the tail cover 8. Preferably, the housing assembly 4 is also provided with a foolproof structure 43, which is matched with the slot of the tail cover 8 to ensure that the engagement position of the housing assembly 4 and the tail cover 8 is accurate.

[0033] An internal step is formed inside the housing assembly 4. A gasket 5, a sealing body 6, a wire clamp 7, and a tail cap 8 are sequentially arranged at one end of the housing assembly 4, with the gasket 5 abutting against the internal step. A shielding outer ring 2 and a shielding inner ring 3 are arranged inside the other end of the housing assembly 4 and abut against the other side of the internal step. A waveform shielding spring 1 is inserted into the shielding outer ring 2. A cable passes through the housing assembly 4, the waveform shielding spring 1, the shielding outer ring 2, the shielding inner ring 3, the gasket 5, the sealing body 6, the wire clamp 7, and the tail cap 8 to form a connector assembly. The shielding layer of the shielded cable is clamped and pressed between the shielding outer ring 2 and the shielding inner ring 3.

[0034] Specifically, the tail of the housing assembly 4 is sequentially fitted with a gasket 5, a sealing body 6, a wire clamp 7, and a tail cap 8. The gasket 5 is limited by the internal steps of the housing assembly, such as... Figure 2As shown, the tail cap 8 is fastened to the housing assembly 4 to prevent it from coming off. The two ends of the sealing body 6 abut against the gasket 5 and the wire clamp 7 respectively. The sealing body is clamped and fixed in the middle for waterproof sealing of the connector assembly tail. The housing assembly 4 is provided with a foolproof structure so that after the tail cap 8 is fastened in place, the wire protection part at the rear end of the tail cap 8 supports the cable to prevent the cable from bending excessively and affecting the sealing effect.

[0035] The outer shielding ring 2 is also riveted and fixed to the waveform shielding spring 1. The outer shielding ring 2 and the inner shielding ring 3 clamp and press the shielding layer of the shielded cable within them, forming shielding conduction between the cable and the waveform shielding spring. The bottom shielding spring of the waveform shielding spring 1 contacts the mounting panel 10 of the customer's enclosure, forming shielding conduction between the connector and the customer's enclosure, realizing the conduction of the connector shielding chain. See Figure 3 As shown.

[0036] Anti-rotation and anti-retraction mechanism of the shielding structure: After the outer shielding ring 2 is installed into place from the housing assembly 4, the shielding spring pieces 21 around the outer shielding ring will spring up and lock into the housing groove of the housing assembly 4. The shielding spring pieces 21 of the outer shielding ring 2 are limited on three sides in the housing groove of the housing assembly, preventing the shield from rotating or retracting inside the housing. At this time, the flanged surface 22 of the outer shielding ring 2 will cooperate with the housing to achieve the limiting effect, preventing it from being pushed further into the housing assembly. See Figure 4 As shown.

[0037] The plastic connector with a shielding structure according to this utility model has the following advantages:

[0038] 1) The unique shielding design relies on the shielding of the outer and inner shielding rings, the crimping of the cable, and the cooperation of the shielding spring and the housing to achieve the effects of preventing rotation and backward movement, ensuring the stability and reliability of the connector, and enabling it to withstand greater mechanical stress and vibration, making it suitable for various complex road environments.

[0039] 2) It is compatible with common mounting panels on the market, making the connector more widely applicable.

[0040] 3) The choice of plastic material not only reduces the weight of the connector, but also improves its corrosion resistance and insulation performance, ensuring the normal operation of the vehicle in harsh environments.

[0041] 4) The contact part between the connector and the housing adopts a wave-shaped shielding spring, which improves the contact stability between the connector shielding structure and the housing and ensures the stability of the connector shielding performance.

[0042] 5) The housing assembly has a foolproof structure, which can effectively avoid installation errors and improve the accuracy and safety of operation.

[0043] 6) The connector is compatible with shielded and unshielded cables ranging from 35 to 70 mm², meeting the high current wire diameter requirements of most vehicles.

[0044] 7) This connector has excellent sealing performance, which can effectively prevent the intrusion of moisture and dust, meet the IP68 performance requirements, and further improve the reliability and service life of the connector.
