Description

[0002] In the new energy vehicle industry, reliable connections of high-voltage shielded cables are crucial. In after-sales maintenance and wiring harness production scenarios, it is often necessary to perform interconnection operations on high-voltage shielded cables. However, existing high-voltage shielded cable connectors have many drawbacks.

[0003] First, the large outer diameter of high-voltage cables makes it difficult to precisely align broken cables manually. Misaligned cables affect the sealing performance of insulators, reduce tensile strength, and weaken bending capabilities. Second, the lack of effective shielding at the connection point allows electromagnetic signals to interfere with the normal operation of other electrical equipment in the vehicle. Furthermore, traditional connection methods, such as hinged connections between the conductor and shielding layer followed by insulation tape and an insulating shell, or the use of flat-plate crimp connectors, generally suffer from problems such as high installation difficulty, cumbersome operation, poor insulation, unstable contact, overheating, insufficient tensile strength, and inability to guarantee sufficient contact area for current carrying capacity. These issues severely restrict the safe and stable operation of high-voltage circuits in new energy vehicles and fail to meet the industry's development needs. Utility Model Content

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figure 1 , Figure 2 and Figure 3 This utility model embodiment provides a high-voltage shielded cable connector for new energy vehicles, comprising:

[0030] The double-ended terminal block 101 is used to connect the conductors of two high-voltage shielded cables. The double-ended terminal block 101 includes a terminal body 1011 and a locking mechanism 1012. The locking mechanism 1012 includes a locking bolt 10121 and a movable pressure block 10122. The locking bolt 10121 fastens the cable conductor to the terminal body 1011.

[0031] Insulator 102 is installed on the outside of double-ended terminal 101, and insulator 102 is made of ceramic material;

[0032] The shielding component 103 is fitted over the insulator 102 and is used to connect the shielding layer of the cable. The shielding component 103 includes a shielding ring linking mechanism 1031 and a shielding shell 1032. The shielding component 103 is locked to the cable shielding layer by bolts.

[0033] A detachable insulating housing 104 is installed outside the shielding component 103. The detachable insulating housing 104 includes a mating terminal insulating housing 1041 and a shielding layer insulating housing 1042. The mating terminal insulating housing 1041 and the shielding layer insulating housing 1042 are locked together by an embedded snap-fit. The inner wall of the detachable insulating housing 104 is provided with PVC insulating soft rubber.

[0034] See Figure 4 and Figure 5 In this embodiment, the terminal body 1011 of the double-ended terminal 101 is made of copper. Both ends of the terminal body 1011 are provided with wire core observation holes. The locking mechanism 1012 includes eight locking bolts 10121 and two movable pressure blocks 10122. The terminal body 1011 is provided with eight threaded blind holes and four positioning pins. The movable pressure blocks 10122 are provided with two positioning holes and four through holes. The locking bolts 10121 fix the movable pressure blocks 10122 to the terminal body 1011.

[0035] Specifically, the double-ended terminal block 101 is a key component for connecting the conductors of two high-voltage shielded cables. The locking mechanism 1012 includes a locking bolt 10121 and a movable pressure block 10122. The terminal body 1011 is made of copper, which has excellent conductivity, ensuring efficient power transmission. Both ends of the terminal body 1011 are designed with wire core observation holes. During installation, operators can directly check through these holes whether the wire core is accurately placed inside the terminal body 1011, ensuring full contact between the wire core and the terminal body 1011 and preventing increased resistance, overheating, or even safety accidents due to poor contact.

[0036] The locking mechanism 1012 operates on the principle of mechanical fastening. The terminal body 1011 has eight threaded blind holes and four locating pins, while the movable pressure block 10122 has two locating holes and four through holes. During installation, the locating holes of the movable pressure block 10122 are first aligned with the locating pins of the terminal body 1011, quickly achieving initial positioning of the movable pressure block 10122 and ensuring accurate installation. Subsequently, eight locking bolts 10121 are passed through the through holes of the movable pressure block 10122 and screwed into the threaded blind holes of the terminal body 1011. As the bolts tighten, the movable pressure block 10122 gradually presses against the cable conductor, ensuring a tight fit with the terminal body 1011 and achieving a reliable electrical connection. This multi-bolt, multi-locating structure design significantly improves the stability and reliability of the connection, effectively preventing cable conductor loosening and ensuring stable power transmission.

[0037] In this embodiment, the insulator 102 is divided into two parts: a base 1021 and a cover 1022. The base 1021 is provided with a limiting groove 10211. The two lower edges of the cover 1022 are inserted into the limiting groove 10211. The base 1021 and the cover 1022 are engaged by a positioning key 1023 to form a cylindrical structure.

[0038] Specifically, the insulator 102 consists of two parts: a base 1021 and a cover 1022. The base 1021 has a limiting groove 10211, and the two lower edges of the cover 1022 are inserted into the limiting groove 10211. The base 1021 and the cover 1022 are engaged by a positioning key 1023. This design not only ensures precise installation of the cover 1022 and the base 1021, but also forms a stable cylindrical structure that tightly wraps around the double-ended terminal block 101. Through this structure, the insulator 102 can provide all-around insulation protection for the double-ended terminal block 101, further improving the insulation performance of the connector and preventing high-voltage leakage.

[0039] The insulator 102 is installed outside the double-ended terminal block 101 and is made of ceramic material. Ceramic can withstand higher voltage and can effectively prevent leakage caused by high voltage breakdown, thus ensuring the safety of personnel and equipment.

[0040] In one possible embodiment, the shielding element 103 is fitted over the insulator 102 and is mainly used as a shielding layer for connecting cables to prevent electromagnetic interference. Its working principle is based on the electromagnetic shielding effect, limiting the electromagnetic signals generated by the cable to a certain range to avoid affecting other electrical equipment in the vehicle.

[0041] In one possible embodiment, the shielding element 103 includes a stainless steel shell 1032 and a copper braided mesh 1032. The stainless steel shell provides basic shielding and mechanical protection, while the copper braided mesh, with its good conductivity and braided structure, can more effectively shield high-frequency electromagnetic waves. The combination of the two significantly improves the shielding effect.

[0042] The shielding component 103 is connected to the cable shielding layer by bolts. When the shielding ring connecting mechanism 1031 of the shielding component 103 is aligned with the cable shielding layer and tightened by bolts, the cable shielding layer becomes conductive, forming a complete circuit in the entire shielding system and effectively shielding electromagnetic signals. In some embodiments, the shielding ring connecting mechanism 1031 and the shielding shell 1032 are integrally formed, and the inner diameter of the shielding ring connecting mechanism 1031 is adapted to the outer diameter of the cable shielding layer. This design further enhances the tightness of the connection and the shielding effect, reducing the possibility of electromagnetic leakage.

[0043] In one possible embodiment, the mating terminal insulating shell 1041 is provided with a locking buckle 10412, and the shielding layer insulating shell 1042 is provided with a locking point 10422; the mating terminal insulating shell 1041 and the shielding layer insulating shell 1042 are connected by an embedded buckle locking method; the inner walls of both the mating terminal insulating shell 1041 and the shielding layer insulating shell 1042 are provided with a PVC insulating soft rubber coating.

[0044] Specifically, the detachable insulating housing 104 is installed outside the shielding component 103, providing dual protection. Firstly, the PVC insulating soft rubber inside, as well as the PVC insulating soft rubber coating on the inner walls of the mating terminal insulating housing 1041 and the shielding layer insulating housing 1042, fills the gaps between components, eliminates air, enhances insulation performance, and prevents leakage. Secondly, it also provides mechanical protection for internal components, preventing external factors from damaging the internal structure.

[0045] The terminal insulating shell 1041 is equipped with a locking buckle 10412, and the shielding layer insulating shell 1042 is equipped with a locking point 10422. They are connected by an embedded buckle locking method. This connection method is simple to operate. During installation, the corresponding locking buckles 10412 and locking points 10422 are simply aligned and fastened. Disassembly is also relatively convenient, and it can ensure the tightness of the connection, so that the entire detachable insulating shell 104 forms a complete protective structure.

[0046] In one possible embodiment, it further includes an outer insulating shell 105, which includes an outer shielding shell cover 1051 and an outer shielding shell 1052. The outer shielding shell cover 1051 and the outer shielding shell 1052 are connected by an embedded snap-locking method. The inner wall of the outer insulating shell 105 is provided with a PVC insulating soft rubber coating. The outer shielding shell cover 1051 is provided with a locking boss, and the outer shielding shell 1052 is provided with a locking buckle 10412.

[0047] Specifically, the outer insulating shell 105 also uses an embedded snap-locking method for connection, consisting of an outer shielding shell cover 1051 and an outer shielding shell 1052. Its inner wall is coated with a PVC insulating soft rubber layer, further enhancing insulation performance. The outer shielding shell cover 1051 has a locking protrusion, and the outer shielding shell 1052 has a locking snap 10412. The two fit tightly together, effectively preventing moisture and dust from entering the connector and providing additional mechanical protection, ensuring stable operation of the connector even in harsh environments.

[0048] In one possible embodiment, the shielding ring linking mechanism 1031 of the shielding component 103 and the shielding shell 1032 are integrally formed, and the inner diameter of the shielding ring linking mechanism 1031 is adapted to the outer diameter of the cable shielding layer. This design further enhances the tightness of the connection and the shielding effect, reducing the possibility of electromagnetic leakage.

[0049] In one possible embodiment, the double-ended terminal block 101 is further covered with a heat-shrink tubing 106, which is heat-shrinked onto the terminal body 1011 by a hot air chamber. The heat-shrink tubing 106 is made of silicone, with an outer wall of silicone heat-shrinkable material and an inner wall of high-temperature hot melt adhesive, capable of withstanding temperatures up to 125°C. It is used to cover the double-ended terminal block and the shielding shell, providing insulation and waterproofing. The hot melt adhesive on the inner wall melts and covers the workpiece surface during heat shrinking, further contributing to waterproofing.

[0050] In one possible embodiment, the insulator 102 is further covered with an insulator heat shrink tubing 107; the insulator heat shrink tubing 107 is heat-shrinkable onto the insulator 102 by hot air blowing. The insulator heat shrink tubing 107 is made of silicone, with an outer wall of silicone heat shrinkable material and an inner wall of high-temperature hot melt adhesive, capable of withstanding temperatures up to 125°C. It is used to cover the outside of the insulator 102, providing insulation and waterproofing. The hot melt adhesive on the inner wall melts and covers the surface of the workpiece during heat shrinking, thus providing waterproofing.

[0051] The assembly process of this utility model is as follows:

[0052] First, install the double-ended terminal block 101: Insert the pre-treated cable conductors into the wiring cavities at both ends of the double-ended terminal block 101, aligning the wire cores with the wire core inspection holes to check the installation status. Then, align the positioning holes of the movable pressure block 10122 with the positioning pins of the terminal body 1011, ensuring the movable pressure block 10122 is accurately positioned. Using a tool, pass the eight locking bolts 10121 sequentially through the through holes of the movable pressure block 10122, screw them into the threaded blind holes of the terminal body 1011, and gradually tighten them until the movable pressure block 10122 firmly presses the cable conductors onto the terminal body 1011.

[0053] Second, insulator 102 installation: Place the assembled double-ended terminal block 101 in place, and fit the base 1021 of the insulator 102 onto the outside of the double-ended terminal block 101, ensuring that the base 1021 fits tightly against the terminal body 1011. Next, align the cover 1022 of the insulator 102 with the limiting groove 10211 and the positioning key 1023 of the base 1021, and slowly insert it so that the two lower edges of the cover 1022 are fully embedded in the limiting groove 10211, forming a stable cylindrical structure, thus completing the installation of the insulator 102.

[0054] Third, installation of shielding component 103: First, slip shielding component 103 onto one section of the cable, paying attention to the orientation of the shielding ring connecting mechanism 1031. Align the cable's shielding layer with the shielding ring connecting mechanism 1031 of shielding component 103, and use bolts to tighten the connection, achieving conductivity of the cable's shielding layer. Then, slip shielding component 103 onto the outside of insulator 102, ensuring its accurate positioning.

[0055] Fourth, installation of the detachable insulating housing 104: The terminal insulating housing 1041 and the shielding layer insulating housing 1042 are installed on the outside of the shielding component 103 using an insert-type snap-locking method. First, align the locking snap 10412 of the terminal insulating housing 1041 with the locking point 10422 of the shielding layer insulating housing 1042 and snap them together to complete the installation of the shielding layer insulating housing 1042 and the terminal insulating housing 1041. Then, install the entire assembly on the outside of the shielding component 103. Ensure that the PVC insulating soft rubber on the inner wall of the detachable insulating housing 104 is in full contact with the internal components, filling gaps and enhancing insulation and protection performance.

[0056] Fifth, installation of the outer insulating shell 105 (if applicable): If the connector includes an outer insulating shell 105, align the locking protrusion of the outer shielding shell cover 1051 with the locking latch 10412 of the outer shielding shell 1052, and install the outer shielding shell cover 1051 and the outer shielding shell 1052 onto the outside of the removable insulating shell 104 using an insert-type latch locking method. Ensure that the PVC insulating soft rubber coating on the inner wall of the outer insulating shell 105 is tightly adhered to the internal components to further enhance the insulation and protection effect.
