[0042] The embodiments of the present application provide a cable connection structure, which can be used in high-voltage cable connection.

[0043] Referring to FIGS. 1-7, the cable connection structure 100 includes a shielding body 1, a first compression ring 31, and a second compression ring 32. The shielding body 1 has at least one axial through accommodating cavity 11 for passing the cable 001. The first compression ring 31 and the second compression ring 32 have a gap for clamping the shielding layer 0013 of the cable 001. One of the first compression ring 31 and the second compression ring 32 is connected with the outer insulation layer 0014 of the cable 001, and the other of the first compression ring 31 and the second compression ring 32 abuts against the shielding body 1.

[0044] The cable 001 has, from inside to outside, a conductor layer 0011, an inner insulation layer 0012, a shielding layer 0013, and an outer insulation layer 0014, and has a connector 0015 at one end for electrical connection with a power device.

[0045] As shown in FIGS. 1, 2, and 7, the shielding body 1 is usually made of metal material to ensure good electromagnetic shielding effect. The shielding body 1 has an axial through accommodating cavity 11 formed inside for passing the cable 001, which can shield the cable 001 while protecting the cable 001 by the accommodating cavity 11, and improve the quality and stability of signal transmission of the cable 001.

[0046] As shown in FIGS. 2, 3, and 7, the shielding body 1 and the shielding layer 0013 of the cable 001 can be connected by the compression assembly 3. Since the compression assembly 3 can tightly abut against the shielding body 1 and fix the shielding layer 0013 of the cable 001, it can effectively prevent the cable 001 from loosening or falling off during connection, thereby ensuring the stable connection between the cable 001 and the shielding body 1 and improving the stability of the entire cable connection structure.

[0047] Moreover, an accommodating groove can be formed in the compression assembly 3 to fix the shielding layer 0013 of the cable 001. This allows the compression assembly 3 to improve the integrity and continuity of the shielding layer 0013 of the cable 001, reduce electromagnetic radiation leakage, and help protect the signal quality transmitted by the cable 001 and reduce the influence of electromagnetic interference on signal transmission. The compression assembly 3 can be an elastic metal, which can be used to connect the shielding body 1 and the outer insulation layer 0014 of the cable 001 by virtue of its elastic deformation capability, and is also convenient for quick installation.

[0048] As shown in FIGS. 2 and 7, the compression assembly 3 can include the first compression ring 31 and the second compression ring 32. Along the radial direction of the cable connection structure 100, the first compression ring 31 and the second compression ring 32 have a gap for clamping the shielding layer 0013 of the cable 001, thereby achieving the connection of the cable 001.

[0049] The first compression ring 31 and the second compression ring 32 are designed to enable the compression assembly 3 to provide uniform and stable compression force to the cable 001, ensuring tight contact between the shielding layer 0013 and the shielding body 1, preventing abnormalities such as loosening or falling off of the cable 001 at the connection. Moreover, since the shielding layer 0013 is clamped between the first compression ring 31 and the second compression ring 32, the risk of loosening and deformation of the shielding layer 0013 is also reduced, thereby ensuring the continuity and integrity of the shielding layer 0013, helping to reduce the leakage of electromagnetic radiation, improve the electromagnetic shielding performance of the cable 001, and ensure the stability and reliability of signal transmission, and also improve the installation convenience.

[0050] In addition, by tightly connecting with the outer insulation layer 0014 of the cable 001 and the shielding body 1, the compression assembly 3 not only fixes the cable 001, but also enhances the stability and integrity of the entire cable connection structure, prolonging the service life of the cable connection structure.

[0051] In another embodiment, the compression assembly 3 can also be provided as an integrally formed structure, that is, the first compression ring 31 and the second compression ring 32 are integrally formed, and a receiving groove is formed between the first compression ring 31 and the second compression ring 32, which is used to connect and fix the shielding layer 0013 of the cable 001.

[0052] In some embodiments, the first compression ring 31 is sleeved outside the outer insulation layer 0014 of the cable 001, and the second compression ring 32 abuts against the shielding body 1.

[0053] As shown in FIGS. 2 and 7, the first compression ring 31 is sleeved outside the outer insulation layer 0014 of the cable 001 and can connect the outer insulation layer 0014 of the cable 001, and the second compression ring 32 abuts against the shielding body 1 and can realize convenient connection of the cable 001 and the shielding body 1.

[0054] In some embodiments, the second compression ring 32 includes a first ring body and a second ring body, and the first ring body and the second ring body have a stepped matching surface therebetween, and the first ring body is located opposite to the first compression ring 31, and the second ring body abuts against the shielding body 1.

[0055] As shown in FIG. 2 and FIG. 7, the first compression ring 31 is located on the inner side, and the second compression ring 32 is located on the outer side. The first ring body and the second ring body of the second compression ring 32 are provided with a stepped matching surface, which can enhance the structural strength and stability of the second compression ring 32. The first ring body and the second ring body are tightly connected through the stepped matching surface to form an integral structure, which also increases the rigidity and anti-deformation ability of the second compression ring 32, so that the second compression ring 32 can better withstand the pressure and tension generated when the cable 001 is connected, ensuring the stability and reliability of the cable 001.

[0056] The first ring body is opposite to the first compression ring 31, and the gap between the first ring body and the first compression ring 31 is used to clamp the shielding layer 0013 of the cable 001, and the second ring body abuts against the shielding body 1, so that the tight fit between the compression assembly 3, the cable 001 and the shielding body 1 can be achieved, the risk of connection failure of the cable 001 caused by gap or looseness can be reduced, and the durability and anti-vibration performance of the cable connection structure can be improved.

[0057] In some embodiments, the second ring body includes a connecting segment and a pressing segment, the connecting segment is connected between the first ring body and the pressing segment, the pressing segment abuts against the shielding body 1, and the connecting segment and the pressing segment have an included angle therebetween.

[0058] As shown in FIG. 2 and FIG. 3, the connecting segment and the pressing segment together form the second ring body, the connecting segment is connected to the first ring body, and the pressing segment abuts against the shielding body 1, so that the connection between the cable 001 and the shielding body 1 can be strengthened by extrusion between the pressing segment and the shielding body 1 during the installation of the cable 001.

[0059] The connecting segment and the pressing segment have an included angle therebetween, for example, a hook-shaped included angle is formed between the connecting segment and the pressing segment in FIG. 3. On the one hand, the compression force between the pressing segment and the shielding body 1 enables the second ring body to form a more tight connection with the shielding body 1, and also reduces the risk of looseness or falling off of the second compression ring 32 when subjected to external force or vibration, thereby enhancing the stability of the entire cable connection structure.

[0060] On the other hand, the design of the included angle between the connecting segment and the pressing segment also ensures that the second compression ring 32 can maintain a stable compression force during long-term use, reduces the risk of failure due to aging or fatigue, and improves the connection reliability of the cable connection structure.

[0061] In another embodiment, the second ring body can also include a first connecting segment, a second connecting segment and a pressing segment, the pressing segment is connected between the first connecting segment and the second connecting segment, the first connecting segment is connected to the first ring body, the pressing segment abuts against the shielding body 1, and the pressing segment and the first connecting segment and the pressing segment and the second connecting segment have an included angle therebetween, as shown in FIG. 3, which can also strengthen the connection between the second ring body and the shielding body 1.

[0062] In some embodiments, a screw connector 21 is further included, a recess 12 is further formed in the shielding body 1, the screw connector 21 is located in the recess 12, one side of the screw connector 21 is connected to the shielding body 1, and the other side of the screw connector 21 is connected to the first compression ring 31 or the second compression ring 32.

[0063] The recess 12 is located in the accommodating cavity 11 and can be used for mounting and fixing the screw connector 21. In the embodiment, one side of the screw connector 21 is connected to the shielding body 1, and the other side of the screw connector 21 is connected to the cable 001 through the first compression ring 31 and the second compression ring 32, so that the two sides of the screw connector 21 can be used to connect and fix the cable 001, and the connection is firm, reliable, simple in process, and convenient for weight reduction and miniaturization. The screw connector 21 can be a metal screw, a conductive plastic screw, a conductive rubber screw or other connection structures.

[0064] In addition, the use of the screw connector 21 also enhances the conductive performance of the cable 001 connection, further improves the signal transmission efficiency of the cable 001. The spiral design of the screw connector 21, i.e., the spiral turns can also increase the connection area of the cable 001 and the shielding body 1, facilitate balanced connection, improve the continuity of electrical connection, reduce the connection impedance between the cable 001 and the shielding body 1, facilitate to improve the shielding effect of the cable connection structure, and the production cost is economical and low. In the assembly process of the cable 001, the contact pressure between the cable 001 and the shielding body 1 can also be adjusted by external force, so as to correspondingly adjust the shielding effect.

[0065] In some embodiments, the screw connector 21 is annular, and the two sides of the screw connector 21 abut against the shielding body 1 and the second compression ring 32, respectively.

[0066] As shown in FIGS. 4-6, the helical connecting member 21 is designed as a ring structure, and each outer periphery of the helical connecting member 21 is connected with the shielding body 1 and the second compression ring 32. On the one hand, the contact area between the helical connecting member 21 and the shielding body 1 and the second compression ring 32 can be increased, thereby improving the stability and reliability of the connection, and the cable connection structure can be kept tightly connected even under abnormal conditions such as external force or vibration, thereby reducing the risk of loosening or even falling off of the cable 001.

[0067] On the other hand, the ring-shaped helical connecting member 21 can also provide a more uniform electromagnetic shielding effect, reduce the leakage of electromagnetic radiation, ensure the signal quality of the cable 001 signal transmission, and reduce the connection impedance between the cable 001 and the shielding body 1.

[0068] The two sides of the helical connecting member 21 are arranged to abut against the shielding body 1 and the second compression ring 32, respectively, that is, during the process of threading the cable 001, the cable 001 can extrude the helical connecting member 21 and the shielding body 1, thereby ensuring the tightness of the connection.

[0069] In some embodiments, the helical connecting member 21 is an elastic body, that is, the helical connecting member 21 can be made of an elastic conductive material, such as an elastic metal, an elastic rubber, etc., which can utilize the elastic deformability to improve the connection tightness between the cable 001 and the shielding body 1.

[0070] In addition, the elastic body has the ability of elastic deformation and elastic reset, so that the helical connecting member 21 also has a certain restoring force. The helical connecting member 21 can be elastically deformed during the connection process to improve the reliability and durability of the cable 001 connection, and can be elastically reset after the connection is released, that is, the external force disappears, thereby facilitating the cyclic use of the cable connection structure and improving the service life of the cable connection structure.

[0071] In some embodiments, a ring-shaped elastic member 22 is further included, and the helical connecting member 21 is wound around the outer periphery of the ring-shaped elastic member 22.

[0072] As shown in FIGS. 2-6, the helical connecting member 21 can be wound around the outer periphery of the ring-shaped elastic member 22 to form a connecting assembly, which can enhance the connection stability and reliability of the connecting assembly. The close combination of the helical connecting member 21 and the ring-shaped elastic member 22 can keep the integrity of the connecting assembly when subjected to external force, and the connecting assembly is not prone to loosening or falling off, thereby enhancing the mechanical strength of the cable connection structure and improving the tensile, torsional and fatigue resistance, etc.

[0073] And the annular elastic member 22 makes the connection assembly have certain elasticity and buffering performance. Due to its excellent elasticity and deformation ability, the annular elastic member 22 can effectively absorb the vibration and impact that the cable 001 may generate during the connection process, reduce the stress concentration between the cable 001 and the connection assembly, thereby protecting the cable 001 and the connection assembly and prolonging the service life thereof. And the annular elastic member 22 can also be elastically reset after the connection is released, i.e. the external force disappears, facilitating the recycling of the cable connection structure and also improving the service life of the cable connection structure. The annular elastic member 22 can be made of an elastic material (such as natural rubber, synthetic rubber, silicone rubber, polyurethane, etc.).

[0074] In addition, the spiral connecting member 21, as a conductive material, can effectively shield electromagnetic interference. The introduction of the annular elastic member 22 does not have a negative impact on the shielding effect, and since the annular elastic member 22 can closely fit the cable 001, it can also enhance the shielding effect to some extent, ensuring that the quality of the signal transmission of the cable 001 is stable and reliable.

[0075] In some embodiments, the spiral connecting member 21 is uniformly wound on the outer periphery of the annular elastic member 22.

[0076] On the one hand, since the spiral connecting member 21 is uniformly distributed on the outer periphery of the annular elastic member 22, the spiral connecting member 21 can provide uniform pressure to the cable 001, avoiding abnormal connection loosening or failure due to uneven pressure distribution, and also improving the stability and reliability of the cable 001 connection.

[0077] And the spiral connecting member 21, as a metal material, has high strength and toughness. When the spiral connecting member 21 is uniformly wound on the annular elastic member 22, the spiral connecting member 21 and the annular elastic member 22 can together form a firm connection assembly that can withstand a large pulling force and torsional force. This enables the cable connection structure to maintain a stable connection state in harsh environments, prolonging the service life and application range.

[0078] On the other hand, since the spiral connecting member 21 is a conductive material, it can effectively shield electromagnetic interference. When the spiral connecting member 21 is uniformly wound on the outer periphery of the annular elastic member 22, they form a continuous shielding layer, which can provide more complete and uniform shielding effect, helping to reduce the leakage of electromagnetic radiation and protect the signal quality transmitted by the cable 001 from interference.

[0079] In some embodiments, a waterproof ring 4 is also included, which is located in the accommodating cavity 11, the outer ring of the waterproof ring 4 abuts against the inner wall of the shielding body 1, and the inner ring of the waterproof ring 4 is used to abut against the cable 001.

[0080] As shown in FIG. 2 and FIG. 7, the waterproof ring 4 is arranged in the accommodating cavity 11, and the outer ring is tightly abutted with the inner wall of the shielding body 1, and the inner ring is abutted with the cable 001. That is, the waterproof ring 4 is sleeved on the outer insulation layer 0014 of the cable 001 and is abutted with the inner wall of the shielding body 1, so as to form an effective waterproof barrier. The waterproof ring 4 can prevent external moisture or humidity from entering the connection area, and also reduces the risk of performance degradation or damage of the cable 001 due to moisture or water.

[0081] Secondly, since the waterproof ring 4 is tightly fitted between the shielding body 1 and the cable 001, the waterproof ring 4 can not only prevent moisture from entering, but also enhance the mechanical strength of the connection part, which helps to reduce the risk of connection loosening or breaking caused by external factors (such as vibration, impact, etc.), thereby prolonging the service life of the cable connection structure. The waterproof ring 4 is also a sealing ring.

[0082] In some embodiments, the shielding body 1 has a plurality of accommodating cavities 11, and the plurality of accommodating cavities 11 are arranged at intervals. Each of the accommodating cavities 11 can pass through a cable 001, and the number of the spiral connectors 21 is the same as the number of the accommodating cavities 11.

[0083] As shown in FIG. 7, by arranging a plurality of accommodating cavities 11 in the same shielding body 1, a plurality of cables 001 can be connected at the same time by using the plurality of accommodating cavities 11, without using a plurality of independent connectors, thereby reducing the time and labor cost required for installation and connection, improving the work efficiency and the capacity of the cable connection structure. Moreover, the plurality of accommodating cavities 11 are arranged at intervals, which helps to reduce the interference and cross between the cables 001.

[0084] Each of the accommodating cavities 11 is provided with a spiral connector 21, so that each cable 001 can be independently fixed and compressed, thereby ensuring the connection reliability of the cable connection structure and reducing the risk of performance degradation or failure caused by improper connection.

[0085] The application also provides a vehicle comprising the above-mentioned cable connection structure 100.
