Description

TECHNICAL FIELD

[0001] The present application relates to a splicing method of a joint cable, particularly a high-voltage shield joint cable, and a cable, particularly a high-voltage shield cable. BACKGROUND

[0002] A shielded electric wire, that is, a shielded cable is a cable having one or more insulated conductors surrounded by a common shield layer. The shield layer is configured to shield electromagnetic noise from each insulated conductor. In particular, by the shield layer, it is possible to suppress the influence of electromagnetic noise that not only affects a signal but also interferes with a machine and a device electrically connected to the cable. The shield layer can also be a braided tube having a plurality of braided wires formed of copper, copper alloy, aluminum, or aluminum alloy. Alternatively, the shield layer can be a non-braided spiral winding of a copper tape or a layer of a conductive polymer. The shield layer is usually covered with an outer sheath corresponding to the outermost layer of the shielded electric wire.

[0003] The shielded electric wire is generally used in a high-voltage harness of a vehicle in order to suppress the influence of electromagnetic noise. In order to simplify the circuit structure, a cable joint is formed in many cases. The cable joint forms a branch in a high-voltage circuit. However, the shielded electric wire having at least one conductor and a conductive shield layer cannot form a joint cable having a high-voltage shield cable, particularly using a conventional cable joint connection technique, because it has a layered structure. In fact, in the conventional joint connection technique, only the conductors of a non-shielded electric wire can be connected.

[0004] However, one technique for splicing a high-voltage shield cable is known. According to the known technique, a rigid metal housing is used in order to electrically connect the shield layer. Generally, the rigid metal housing formed by drawing processing or die casting processing is provided to be separated and cover the electrically connected conductors. By the rigid metal housing, it is possible to form an electrical connection between the shield layers of the shielded cables in the joint. In addition, the rigid metal housing is mechanically connected to the shielded cable by a crimp connector. Furthermore, a plastic housing is generally provided under the rigid metal housing in order to surround each conductor and electrically separate it from the shield layer. Finally, a waterproof member for covering the metal housing is provided to waterproof the joint cable. The waterproof member is sometimes connected to the metal housing by a rubber seal.

[0005] The above-mentioned conventional joint connection technique has a disadvantage associated with the rigid metal housing used for electrically connecting the shield layer in the joint cable. Since the metal housing is rigid in structure, the shape of the joint connection is determined by the shape of the metal housing. In other words, the rigid metal housing cannot be used for the joint connection of a cable configured in a different configuration from the design and / or shape of the metal housing. For example, the metal housing cannot be used for the joint connection of a cable configured in a manner to form a different angle, for example, 60°, in the case of a joint connection of three cables specially designed to be configured in a manner that two of the three cables form an angle of 30° therebetween. In summary, the rigid metal housing used in the conventional joint connection technique cannot easily be adapted to the joint connection of a shielded cable having a configuration different from the design and / or shape of the metal housing.

[0006] A further disadvantage of the conventional joint connection technique is associated with the plurality of components used for the joint connection of the shielded cable. According to the above-mentioned technique, first, the conductors are electrically connected. Then, a first plastic housing is provided in order to surround each conductor and electrically separate it from the shield layer. The plastic housing is typically formed by a pair of complementary housings connected to each other by an adhesive material such as paste or a mechanical means such as a screw. Next, a rigid metal housing is provided in order to cover the isolated and electrically connected conductors and the plastic housing. The rigid metal housing is connected to the shield layer by a crimp connector. Finally, a waterproof member is provided in a manner to cover the rigid metal housing. Obviously, in the above-mentioned known joint connection technique, the joint connection of the shielded cable requires many assembly components and processes. SUMMARY

[0051] With reference to the above-described figures, a joint cable 1 according to an embodiment of the present application, in particular a high-voltage joint cable, is described herein. In particular, the joint cable 1 is particularly suitable for use in connection with a Y-type distribution (or splitter) unit having one input line and two (or more) output lines. In the present description, the term "high-voltage" particularly refers to a voltage value substantially higher than about 40 volts (e.g. about 48 V) and / or a direct current voltage of about 900 V. Further, a typical joint cable acting as a splitter unit is capable of distributing electrical power of e.g. about 5 A to about 300 A to several high-voltage components.

[0052] Thus, the joint cable 1 according to the embodiment is a joint cable suitable for use in a circuit having a voltage value substantially higher than about 40 volts.

[0053] With reference to Figures 1-4 , the joint cable 1 is shown in an assembled state. The joint cable 1 comprises a first shielded electrical line 2a, a second shielded electrical line 2b and a third shielded electrical line 2c. As shown in Figure 1 and Figure 2 , the first shielded electrical line 2a is arranged at a first side 100a of the joint cable 1, and the second shielded electrical line 2b and the third shielded electrical line 2c are substantially arranged at a second side 100b of the joint cable 1. The first side 100a of the joint cable 1 is substantially opposite to the second side 100b of the joint cable 1. In particular, the second shielded electrical line 2b and the third shielded electrical line 2c can also be arranged substantially adjacent to each other and / or substantially parallel to each other. Preferably, the second shielded electrical line 2b and the third shielded electrical line 2c can also be substantially parallel to each other for a certain (pre-determined or pre-determinable) distance, e.g. substantially parallel to each other in a region where the shielded electrical lines are connected to each other.

[0054] As shown in Figure 1 and Figure 2 , the second shielded electrical line 2b and the third shielded electrical line 2c can also be arranged in a substantially branched manner. In other words, the second shielded electrical line 2b and the third shielded electrical line 2c can also be arranged in a manner forming an angle "a" between each other. The angle "a" can preferably be less than 180°, more preferably less than 90°, and further preferably about 45°. With reference to Figure 10 , the first shielded electrical line 2a is electrically connected to the second shielded electrical line 2b and the third shielded electrical line 2c. The shielded electrical lines 2a, 2b and 2c are electrically connected in a middle (in particular central) portion 100c of the joint cable 1. The electrical connection between the shielded electrical lines 2a, 2b, 2c will be described in detail in the following paragraphs.

[0055] Next, reference is made to Figure 5The structure of the first shielded electric wire 2a will be described here. The detailed description of the structure of the shielded electric wire according to the embodiment of the present application is given only for the first shielded electric wire 2a, but the second shielded electric wire 2b and the third shielded electric wire 2c also have structures similar to or substantially the same as the structure described below for the first shielded electric wire 2a. In other words, the first shielded electric wire 2a, the second shielded electric wire 2b, and the third shielded electric wire 2c have substantially the same structure. As shown in FIG. 1, the first shielded electric wire 2a has at least one conductor 7a, at least one insulating layer 8a, at least one first shield layer 3a, and at least one first outer sheath 4a in this order. In particular, the first shielded electric wire 2a can have a single conductor 7a. Alternatively, the first shielded electric wire 2a can have a plurality of conductors 7a twisted or arranged substantially in parallel with each other, in particular. Figure 5

[0056] The conductor 7a can have a single wire and / or a twisted wire made of any material suitable for electric power conduction, such as copper, copper alloy, aluminum, aluminum alloy, or other metal material suitable for electric power conduction. In particular, the conductor 7a can be formed as a round wire having a substantially circular cross section. Alternatively, the conductor 7a can have a substantially polygonal cross section, such as a substantially square, a substantially rectangular, a substantially hexagonal, or the like, for example. The second shielded electric wire 2b and the third shielded electric wire 2c have structures similar to or substantially the same as each other, and / or have at least one conductor 7b and at least one conductor 7c made substantially of the same material as the material of the conductor 7a of the first shielded electric wire 2a, in particular. The at least one conductor 7a, 7b, 7c can have a cross-sectional dimension in the range of about 2.5 mm 2 to about 120 mm 2 , in particular.

[0057] Referring to Figure 5 , the first shielded electric wire 2a has the first insulating layer 8a formed of an electrically insulating material. The first insulating layer 8a is arranged to cover the outer surface of the at least one conductor 7a integrally or as a whole in a manner that the conductor 7a is electrically separated. The first insulating layer 8a can be formed of any material suitable for electrically separating the conductor 7a. For example, the insulating layer 8a can be formed of a thermoplastic polymer material. In particular, the insulating layer 8a can be formed of, or can include, polyvinyl chloride resin (PVC), polyethylene (PE) resin, or polypropylene (PP) resin, or silicone rubber (SiR), for example. The second shielded electric wire 2b and the third shielded electric wire 2c have the second insulating layer 8b and the third insulating layer 8c, respectively. The insulating layers 8b and 8c have substantially similar or identical structures, and / or are formed substantially of the same material as the material of the insulating layer 8a of the first shielded electric wire 2a, in particular.

[0058] Referring next to Figure 5 ​The first shielded electric wire 2a has a first shield layer 3a. The first shield layer 3a is arranged in a manner of integrally or wholly covering the outer surface of the insulating layer 8a. In particular, the first shield layer 3a can also have a cylindrical braided member. More particularly, the cylindrical braided member can also be formed by subjecting a plurality of electric wires formed of an electrically conductive material to a braiding process or a knitting process. For example, the electric wires forming the cylindrical braided member can also be formed of any suitable metal material. In particular, the shield layer 3a can also be formed of a metal material suitable for suppressing electromagnetic noise capable of exerting an influence on the electric wires 2a, 2b and 2c. Preferably, the shield layer 3a can also be formed of copper, a copper alloy, aluminum or an aluminum alloy. The surface of the electric wires of the shield layer 3a can also be subjected to plating with nickel or silver or gold, for example. Alternatively or in addition, the first shield layer 3a can also have a foil shield layer including, in particular, an electrically conductive (e.g., metal) foil or an electrically conductive (e.g., metal) tape. In particular, the shield layer 3a can have both a braided shield layer and a composite foil shield layer (ALU-PET foil or the like) including an electrically conductive component and a non-conductive component, and the electrically conductive component of the composite foil can be in electrical contact with the braided shield layer.

[0059] In other words, the shield layer 3a is a layer configured to shield the conductor 7a from electromagnetic noise. Alternatively or in addition, the first shield layer 3a can also have a metal foil arranged on the outer surface of the insulating layer 8a in a manner of being formed in a spiral shape. Although not described, the second shielded electric wire 2b and the third shielded electric wire 2c each have a second shield layer 3b and a third shield layer 3c, respectively. The shield layers 3b and 3c have substantially the same structure, configuration, suitability, and / or are substantially formed of the same materials as those described for the first shield layer 3a of the first shielded electric wire 2a.

[0060] Next, with reference to Figure 5 The first shielded electric wire 2a has a first outer sheath 4a. The first outer sheath 4a is arranged in a manner of integrally or wholly covering the outer surface 30a of the shield layer 3a. That is, the outer surface 30a of the first shield layer 3a is integrally or wholly covered by the first outer sheath 4a. As Figure 5The outer sheath 4a is substantially the outermost layer of the first shielded electric wire 2a. Preferably, the outer sheath 4a comprises an electrically insulating material. More preferably, the outer sheath 4a can also be formed of a material configured to electrically separate the first shielded electric wire 2a, and in particular, can also be a water-repellent outer sheath. In particular, the first outer sheath 4a can for example be formed of or comprise a thermoplastic polymer material such as a polyvinyl chloride (PVC) resin, a polyethylene (PE) resin, or a polypropylene (PP) resin, or a silicone rubber (SiR), and the like. Although not specifically illustrated, the second shielded electric wire 2b and the third shielded electric wire 2c each have a second outer sheath 4b and a third outer sheath 4c, respectively. The second outer sheath 4b and the third outer sheath 4c can have substantially the same structure, configuration, suitability, and / or be formed of the same materials as the first outer sheath 4a of the first shielded electric wire 2a.

[0061] In general, the structure, configuration, and materials of the first shielded electric wire 2a described above can substantially correspond to the structure, configuration, and materials of the second shielded electric wire 2b and / or the third shielded electric wire 2c. In other words, the second shielded electric wire 2b and the third shielded electric wire 2c particularly include the same structure, configuration, shape, and materials as the conductor 7a, the insulating layer 8a, the shield layer 3a, and / or the outer sheath 4a of the first shielded electric wire 2a described above. For completeness, as Figures 8-14 illustrated, the second shielded electric wire 2b has a second conductor 7b, a second insulating layer 8b, and a second shield layer 3b, the outer surface 30 of which is covered by a second outer sheath 4b. The third shielded electric wire 2c has a third conductor 7c, a third insulating layer 8c, and a third shield layer 3c, the outer surface 30 of which is covered by a third outer sheath 4c.

[0062] Referring to Figure 7 and Figure 10 In the joint electric cable 1 of one embodiment of the present application, the first conductor 7a of the first shielded electric wire 2a is electrically connected to the second conductor 7b of the second shielded electric wire 2b and the third conductor 7c of the third shielded electric wire 2c. Preferably, the first conductor 7a can be welded to the second conductor 7b and the third conductor 7c as Figure 7 illustrated in detail. More preferably, the first conductor 7a can be ultrasonic-welded, ultrasonic-welding-applied, resistance-welded, magnetic pulse-welded, soldered, brazed, and / or crimped to the second conductor 7b and / or the third conductor 7c. In particular, the end portions of the first conductor 7a, the second conductor 7b, and / or the third conductor 7c can each be arranged substantially parallel to each other, thereby being electrically connected to each other. In particular, as Figure 7 illustrated, the first conductor 7a can be interposed between the second conductor 7b and the third conductor 7c, and electrically connected thereto.

[0063] Referring next toFigure 7 And Figure 11 The joint cable 1 can also have an isolation layer 10 provided in the middle (particularly, the center) portion 100c of the joint cable 1, particularly, in the portion where the conductors 7a, 7b and 7c are electrically connected to each other. Particularly, the isolation layer 10 can be or have a heat shrinkable tubular member and / or an insulating tape (silicone tape or the like) configured to cover the first conductor 7a, the second conductor 7b and the third conductor 7c substantially in the middle (particularly, the center) portion 100c of the joint cable 1, particularly, in the portion where the conductors 7a, 7b and 7c are electrically connected to each other. The isolation layer 10 can also be a layer configured to electrically separate the conductors 7a, 7b and 7c. For example, the isolation layer 10 can include a material suitable for electrically separating the conductors 7a, 7b and 7c. Also, the isolation layer 10 can be formed of a material that shrinks when heated to a temperature higher than a given temperature, or have a shrinkable tubular member including the material, whereby, when heated, the shrinkable tubular member substantially takes the shape of the electrically connected conductors 7a, 7b and 7c located thereunder by shrinking. Particularly, the isolation layer 10 can be a thermoplastic polymer material. Specifically, the isolation layer 10 can be formed of or include any one of various thermoplastics including polyolefin, polyvinyl chloride (PVC), Viton (registered trademark) (particularly, for high-temperature and / or corrosive environments), Neoprene (registered trademark), polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP) and / or Kynar (registered trademark). Further specifically, in addition to these polymers, the isolation layer 10 can include an adhesive liner that promotes adhesion of the isolation layer 10 to a structure located thereunder such as the electrically connected conductors 7a, 7b and 7c, and / or any tape (e.g., silicone tape or the like) provided thereon.

[0064] As shown in Figure 11 The isolation layer 10 can also be configured to overlap at least the exposed portions of the respective insulating layers 8a, 8b and 8c of the first, second and third shielded electric wires 2a, 2b and 2c, respectively. According to this configuration, the insulating layer 8a of the first shielded electric wire 2a is seamlessly connected to the respective insulating layers 8b and 8c of the second and third shielded electric wires 2b and 2c by the isolation layer 10.

[0065] Next, reference is made to Figures 6-8 and Figure 12The connector cable 1 further includes a flexible shielding tube 5. The shielding tube 5 is formed as a flexible part, that is, the shape of the shielding tube 5 can substantially correspond to the shape of the part surrounded by the shielding tube 5. Therefore, when the flexible shielding tube 5 surrounds a generally straight part, the flexible shielding tube 5 can substantially obtain a generally straight shape that substantially corresponds to the shape of the surrounded part, and when the flexible shielding tube 5 surrounds a generally arc-shaped part, the flexible shielding tube 5 can substantially obtain a corresponding generally arc-shaped shape. The flexible shielding tube 5 may also be configured as a generally cylindrical part that integrally or entirely surrounds the sub-assembly 100d of the connector cable, including at least a portion of the electrically connected conductors 7a, 7b, 7c, the insulation layers 8a, 8b, 8c, the isolation layer 10 surrounding or enclosing the electrically connected conductors 7a, 7b, 7c, and at least a portion of each of the first shielding layer 3a, the second shielding layer 3b, and the third shielding layer 3c.

[0066] The flexible shielding tube 5 has a first portion 50a and a second portion 50b that are adjacent to or separate from each other in the longitudinal direction. Specifically, the first portion 50a of the flexible shielding tube 5 may be a first end of the flexible shielding tube 5, and the second portion 50b of the flexible shielding tube 5 may be a second end of the flexible shielding tube 5 that is substantially opposite to the first end of the flexible shielding tube 5 in the longitudinal direction. Figure 12 As shown, the first portion 50a of the flexible shielding tube 5 is configured to substantially surround or enclose the exposed portion 31a of the first shielding wire 2a, and the second portion 50b of the flexible shielding tube 5 is configured to substantially surround or enclose both the exposed portions 31b of the second shielding wire 2b and the exposed portions 31c of the third shielding wire 2c. In particular, the exposed portions 31a, 31b, and 31c of the first shielding wire 2a, the second shielding wire 2b, and / or the third shielding wire 2c may also be the exposed ends of the first shielding wire 2a, the second shielding wire 2b, and / or the third shielding wire 2c, respectively.

[0067] More specifically, the exposed portions 31a, 31b, and 31c of the first shielded wire 2a, the second shielded wire 2b, and the third shielded wire 2c can also be the exposed portions or exposed ends of the first, second, and third shielding layers 3a, 3b, and 3c, respectively, by peeling off a portion of the first, second, and third outer sheaths 4a, 4b, and 4c.

[0068] Next refer to Figures 6-8 and Figure 12The first portion 50a of the flexible shield tube 5 is a structure for electrically connecting with the first shield layer 3a, and the second portion 50b of the flexible shield tube 5 is a structure for electrically connecting with both the second shield layer 3b and the third shield layer 3c.

[0069] As shown in Figure 7 and Figure 8 The first portion 50a of the flexible shield tube 5 defines a substantially circular first opening 53a of the first shielded electric wire 2a. Therefore, the inner surface 51 of the flexible shield tube 5 can also be configured to substantially abut against the outer surface 30a of the first shield layer 3a in a manner that the flexible shield tube 5 and the first shield layer 3a of the first shielded electric cable 2a can be electrically connected. Likewise, the second portion 50b of the flexible shield tube 5 defines a substantially circular second opening 53b of the second shielded electric wire 2b and the third shielded electric wire 2c. In particular, the inner surface 51 of the flexible shield tube 5 can also be configured to substantially abut against both the outer surface 30b of the second shield layer 3b and the outer surface 30c of the third shield layer 3c in a manner that the flexible shield tube 5 and the second shield layer 3b of the second shielded electric wire 2b, and the flexible shield tube 5 and the third shield layer 3c of the third shielded electric wire 2c can be electrically connected.

[0070] In particular, as shown in Figure 6 and Figure 8 The range of the surface of the first opening 53a in the first portion 50a (cross section B-B) as the area of the first opening can also be smaller than the range of the surface of the second opening 53b in the second portion 50b of the flexible shield tube 5 (cross section D-D) which surrounds the second shielded electric wire 2b and the third shielded electric wire 2c. In other words, the flexible shield tube 5 can also be formed as a tapered tube which substantially has a conical shape.

[0071] In particular, the flexible shield tube 5 can also be a braided tube. Preferably, the braided tube 5 can be formed by braiding or knitting a plurality of electric wires formed of an electrically conductive material. For example, the electric wires forming the flexible shield tube 5 can be formed of an appropriate metal material configured to suppress the influence of electromagnetic noise. The flexible shield tube 5 can be formed of a metal resin composite of copper, copper alloy, aluminum or aluminum alloy, copper and polyester (monofilament or multifilament), aluminum and polyester (monofilament or multifilament), or the like. The surface of the electric wires of the shield tube 5 can be plated with nickel, silver, or gold.

[0072] Therefore, the joint cable 1 electrically connected with the shielded electric wires 2a, 2b and 2c is also able to shield the influence of electromagnetic noise as with each shielded electric wire. Alternatively or additionally, the flexible shielded tube 5 can also have a metal foil (copper / PET foil or aluminum / PET foil or the like) or a metal layer configured to surround a subassembly 100d of the joint cable including the electrically connected conductors 7a, 7b, 7c, the insulating layer 10 surrounding the electrically connected conductors 7a, 7b, 7c, the first shield layer 3a, the second shield layer 3b and the third shield layer 3c.

[0073] Further particularly, the flexible shielded tube 5 can also be provided with an elastically deformable material to impart an elastic property or a spring property to the flexible shielded tube 5 to elastically surround the subassembly 100d. In other words, the flexible shielded tube 5 can also be configured to elastically or springingly adhere to the subassembly 100d in a manner to substantially take the shape of the subassembly 100d located thereunder.

[0074] Particularly, as shown in Figure 6 , Figure 8 and Figure 10 , the exposed portion 31a of the first shielded electric wire 2a can also include a portion of the first shield layer 3a that has been stripped of the first outer sheath 4a in a manner to expose an outer surface 30a of the first shield layer 3a. Preferably, the portion of the first shield layer 3a that has been stripped of the first outer sheath 4a can also be interposed between the pair of portions 310a of the first shield layer 3a that are covered by the first outer sheath 4a. Particularly, the inner surface 51 of the flexible shielded tube 5 can also be configured to substantially abut the outer surface 30a of the first shield layer 3a at the exposed portion 31a between the pair of portions 310a covered by the outer sheath 4a. More preferably, the exposed portion 31a of the first shielded electric wire 2a can also be an exposed end portion of the first shielded electric wire 2a.

[0075] In particular, the exposed portion 31b of the second shielded electric wire layer 2b can also include a portion of the second shield layer 3b that is stripped of the second outer sheath 4b in a manner that the outer surface 30b of the second shield layer 3b is exposed. Preferably, the portion of the second shield layer 3b that is stripped of the second outer sheath 4b can also be interposed between the pair of portions 310b of the second shield layer 3b that are covered by the second outer sheath 4b. In particular, the inner surface 51 of the flexible shield tube 5 can also be configured to substantially abut the outer surface 30b of the second shield layer 3b at the exposed portion 31b interposed between the pair of portions 310b of the second shield layer 3b that are covered by the second outer sheath 4b. More preferably, the exposed portion 31a of the first shielded electric wire 2a can also be a substantially exposed end portion of the first shielded electric wire 2a. In particular, the exposed portion 31c of the third shielded electric wire can also include a portion of the third shield layer 3c that is stripped of the third outer sheath 4c in a manner that the outer surface 30c of the third shield layer 3c is substantially exposed. The exposed portion of the third shield layer 3c that is stripped of the third outer sheath 4c can also be interposed between the pair of portions 310c of the third shield layer 3c that are covered by the third outer sheath 4c. In particular, the inner surface 51 of the flexible shield tube 5 can also be configured to substantially abut the outer surface 30c of the third shield layer 3c at the exposed portion 31c interposed between the pair of portions 310c of the third shield layer 3c that are covered by the third outer sheath 4c. More preferably, the exposed portion 31c of the third shielded electric wire 2c can also be a substantially exposed end portion of the third shielded electric wire 2c.

[0076] Alternatively, the exposed portion 31a of the first shielded electric wire 2a can also include an exposed end portion of the first shield layer 3a that can be interposed between stripped portions of the conductor 7a that are electrically connected to the second conductor 7b, the third conductor 7c, and the portion of the first shield layer 3a that is covered by the other first outer sheath 4a. In other words, according to the present embodiment, the exposed portion of the first shield layer 3a can be interposed between the exposed portion of the conductor 7a and a portion of the first outer sheath 4a. Likewise, the exposed portion 31b of the second shielded electric wire layer 2b and the exposed portion 3c of the third shielded electric wire layer 2c can also have such additional configurations as described for the exposed portion 31a of the first shielded electric wire 2a.

[0077] As shown in Figure 6 , Figure 8 and Figure 10 , the joint cable 1 can further have at least one connecting member 6. The connecting member 6 can be a member configured to mechanically and / or electrically connect the flexible shield tube 5 with the first shielded electric wire 2a, the second shielded electric wire 2b, and the third shielded electric wire 2c.

[0078] As shown in Figure 6 , Figure 8 and Figure 10As shown, the connection member 6 can also have at least one first adhesive tape 6a and / or at least one second adhesive tape 6b. The adhesive tapes 6a, 6b can also be electrically insulating tapes capable of electrically insulating the electrically conductive electric wires. As shown, the first adhesive tape 6a can substantially be configured to surround or cover at least a portion 520a, preferably the end portion, of the outer surface 52 of the flexible shielding tube 5 and at least a portion of the outer surface 40a of the first outer sheath 4a in such a manner as to mechanically and / or electrically connect the flexible shielding tube 5 with the first shielding electric wire 2a. In other words, the adhesive tape 6a can also be wound around the joint electric cable 1 by substantially forming a spiral shape that covers both the at least a portion of the outer surface 52 of the flexible shielding tube 5 and the at least a portion of the outer surface 40a of the first outer sheath 4a. By this configuration, the flexible shielding tube 5 can be seamlessly connected with the first shielding electric wire 2a, particularly the first shielding layer 3a. Figure 13 As shown, the first adhesive tape 6a can substantially be configured to surround or cover at least a portion 520a, preferably the end portion, of the outer surface 52 of the flexible shielding tube 5 and at least a portion of the outer surface 40a of the first outer sheath 4a in such a manner as to mechanically and / or electrically connect the flexible shielding tube 5 with the first shielding electric wire 2a. In other words, the adhesive tape 6a can also be wound around the joint electric cable 1 by substantially forming a spiral shape that covers both the at least a portion of the outer surface 52 of the flexible shielding tube 5 and the at least a portion of the outer surface 40a of the first outer sheath 4a. By this configuration, the flexible shielding tube 5 can be seamlessly connected with the first shielding electric wire 2a, particularly the first shielding layer 3a.

[0079] The second adhesive tape 6b can also be configured to surround or cover at least a portion 520b, preferably the end portion, of the outer surface 52 of the flexible shielding tube 5, at least a portion of the outer surface 40b of the second outer sheath 4b, and at least a portion of the outer surface 40c of the third outer sheath 4c in such a manner as to mechanically and / or electrically connect the flexible shielding tube 5 with the second shielding electric wire 2b and the third shielding electric wire 2c. In other words, the second adhesive tape 6b can also be wound around the joint electric cable 1 by substantially forming a spiral shape that covers both the outer surface 52 of the flexible shielding tube 5 and the outer surfaces 40b and 40c of the second and third outer sheaths 4b and 4c, respectively. By this configuration, the flexible shielding tube 5 can be substantially seamlessly mechanically and / or electrically connected with the second shielding electric wire 2b and the third shielding electric wire 2c, particularly the second shielding layer 3b and the third shielding layer 3c.

[0080] In particular, the at least one connection member 6 can also have at least one first binding tape and at least one second binding tape (not shown in the drawings). The binding tapes can be configured to permanently bind the flexible shielding tube 5 on the underside of the shielding electric wires 2a, 2b, 2c (the portion of the shielding electric wires that is surrounded by the flexible tube 5, i.e., the exposed portions 31a, 31b, 31c of the shielding electric wires 2a, 2b, 2c) when the outer surface 52 of the flexible shielding tube 5 is integrally surrounded and the binding tapes and the flexible shielding tube 5 are connected together. The first binding tape can be configured to bind at least a portion 520a, preferably the end portion, of the outer surface 52 of the flexible shielding tube 5 over the exposed end portion 31a of the first shielding layer 3a of the first shielding electric wire 2a. According to this structure, the flexible shielding tube 5 can be seamlessly (electrically and / or mechanically) connected with the first shielding electric wire 2a, particularly the first shielding layer 3a.

[0081] The second bundle can also be configured to bundle at least a portion 520b, preferably the end, of the outer surface 52 of the flexible shielding tube 5, which is opposed in the longitudinal direction to another portion 520a of the outer surface 52 of the flexible shielding tube 5. Specifically, the second bundle can also be configured to bundle at least a portion 520b of the outer surface 52 of the flexible shielding tube 5 across the exposed portions 31b and 31c below the second shielded wire and the third shielded wire 2b and 2c. According to this structure, the flexible shielding tube 5 can therefore be seamlessly (electrically and / or mechanically) connected to the second shielded wire 2b and the third shielded wire 2c.

[0082] Specifically, although not illustrated in the accompanying drawings, the connecting part 6 may also have a first clamping member or crimp connector and / or a second clamping member or crimp connector. The first clamping member or crimp connector may also be configured to surround or enclose at least a portion 520a of the outer surface 52 of the flexible shielding tube 5, preferably the end portion, and at least a portion of the outer surface 40a of the first outer sheath 4a, in a manner that mechanically and / or electrically connects the flexible shielding tube 5 to the first shielding wire 2a, and integrally crimp them (by deformation). The second clamping member or crimp connector may also be configured to surround or enclose at least a portion 520b of the outer surface 52 of the flexible shielding tube 5, preferably the end portion, at least a portion of the outer surface 40b of the second outer sheath 4b, and at least a portion of the outer surface 40c of the third outer sheath 4c, in a manner that mechanically and / or electrically connects the flexible shielding tube 5 to the second shielding wire 2b and the third shielding wire 2c, and integrally crimp them (by deformation).

[0083] Specifically, the flexible shielding tube 5, the first outer sheath 4a, the second outer sheath 4b, and the third outer sheath 4c can also have substantially equal thicknesses. Preferably, the thickness of the flexible shielding tube 5 can also be thinner than the thicknesses of the first outer sheath 4a, the second outer sheath 4b, and the third outer sheath 4c. Advantageously, by constructing the flexible shielding tube 5 with a thickness thinner than that of the first, second, and third outer sheaths 4a, 4b, and 4c, height differences at the locations where the adhesive tape is wrapped can be avoided.

[0084] In particular, such as Figures 7-9 and Figure 14 As shown, the connector cable 1 may further include a waterproof component or a housing 9. The waterproof component 9 may also be configured such that the flexible shielding tube 5 substantially surrounds the central portion 100c of the connector cable 1 in a manner that imparts waterproofness to the connector cable 1. The waterproof component 9 may also be, for example, a waterproof molded part. The waterproof component 9 may also be a thermoplastic polymer or a thermosetting polymer. Preferably, the waterproof component 9 may also be formed of polyvinyl chloride resin, polyethylene resin, polypropylene resin, or polyurethane resin (PUR).

[0085] In particular, the waterproof part 9 may also have two complementary connectable shells configured to surround the central part 100c, which is electrically connected to the conductors 7a, 7b, 7c in the connector cable 1, the flexible shielding tube 5, the adhesive tapes 6a, 6b and other connecting parts 6.

[0086] Connector cable 1 can also be part of a circuit, particularly a high-voltage circuit. In other words, connector cable 1 can also be a branch of a circuit, particularly a high-voltage circuit. The circuit can be, for example, the circuit of a hybrid vehicle, an electric vehicle, etc. As an example of application, circuits that provide power to motors, charging units, energy storage units, high-voltage (HV) units, air conditioning compressors and / or positive temperature coefficient (PTC) auxiliary heaters and / or connections from the charging socket to the charging unit can be listed. Connector cable 1 can also be used in automotive interiors, such as in sensor cables, control cables, and / or power cables in the engine compartment. Alternatively, or on this basis, connector cable 1 can be associated with general power lines and can also be used in the telecommunications field. In particular, connector cable 1 can be used specifically as a splitter unit, and more specifically as a Y-type power distribution (or splitter) unit having one input line and two (or more) output lines.

[0087] Next refer to Figures 10-14 Hereinafter, a cable connector connection method according to an embodiment of the present invention will be described.

[0088] Therefore, the connector of the first shielded cable 2a is connected to the second shielded cable 3a and the third shielded cable 4a.

[0089] like Figure 10 As shown, a first shielded wire 2a, a second shielded wire 2b, and a third shielded wire 2c are installed according to a specific first process. The first shielded wire 2a has a first conductor 7a and a first shielding layer 3a whose outer surface 30a is covered by a first outer sheath 4a. The second shielded wire 2b has a second conductor 7b and a second shielding layer 3b whose outer surface 30b is covered by a second outer sheath 4b. The third shielded wire 2c has a third conductor 7c and a third shielding layer 3c whose outer surface 30c is covered by a third outer sheath 4c.

[0090] like Figure 10As shown, according to a specific second step, the first conductor 7a is electrically connected to at least the second conductor 7b and / or the third conductor 7b. To electrically connect conductors 7a, 7b, and 7c, the outer sheaths 4a, 4b, 4c, shielding layers 3a, 3b, 3c, and insulation layers 8a, 8b, 8c of each shielded wire 2a, 2b, 2c are stripped so that at least partially exposed portions of each conductor 7a, 7b, and 7c (particularly their ends). Next, the first conductor 7a is electrically connected to the second conductor 7b and the third conductor 7c. For example, conductors 7a, 7b, and 7c can also be electrically connected by solid-state bonding, preferably by ultrasonic welding. Alternatively, the conductors can be soft-soldered to each other. Alternatively, conductors 7a, 7b, and 7c can be configured to be substantially in contact with each other in a way that forms an electrical connection between them. Preferably, conductors 7a, 7b, and 7c can also be mechanically connected to each other in a way that maintains the electrical connection between them (e.g., by molding, etc.).

[0091] In particular, the first conductor 7a can be positioned between the second conductor 7b and the third conductor 7c, and electrically connected to both the second conductor 7b on the first side and the third conductor 7c on the second side.

[0092] like Figure 11 As shown, the insulating layer 10 can also be provided in a specific third (arbitrary) step of the connector connection method. Specifically, the insulating layer 10 can also be a cylindrical part suitable for surrounding and covering the first conductor 7a, the second conductor 7b, and the third conductor 7c in the central portion 100c where conductors 7a, 7b, and 7c are electrically connected in the connector cable 1. The insulating layer 10 can also be a layer configured to electrically separate conductors 7a, 7b, and 7c as described above. Specifically, the insulating layer 10 can also contain a material suitable for electrically separating conductors 7a, 7b, and 7c.

[0093] Furthermore, the insulating layer 10 may also (e.g., in the form of a tubular component) contain a material that shrinks when heated to a temperature above a given temperature depending on the material of the insulating layer itself. Thus, when heated to a temperature above a given temperature, the insulating layer 10 shrinks over the conductors and takes the shape of the conductors 7a, 7b, and 7c of the electrical connections located thereunder.

[0094] like Figure 11 As shown, the insulating layer 10 can first be introduced onto the connector cable 1 in a manner that covers the central portion 100c, in particular, the electrical connection of conductors 7a, 7b, and 7c in the connector cable 1. Then, a heating element (in...) can also be used... Figure 11 (Not shown in the figure) The insulating layer 10 is heated to shrink over conductors 7a, 7b and 7c and embed them. Alternatively, the insulating layer 10 can be wrapped around or secured to the connector cable 1, particularly to the electrically connected conductors 7a, 7b and 7c.

[0095] Next refer toFigure 12 The flexible shield tube 5 is provided according to a specific 4th process of the above-described method. The flexible shield tube 5 has a 1st portion 50a and a 2nd portion 50b which is opposite to the 1st portion 50a in the length direction, the 1st portion 50a of the flexible shield tube 5 is configured to substantially surround the exposed portion 31a of the 1st shielded electric wire 2a, and the 2nd portion 50b of the flexible shield tube 5 is configured to substantially surround both of the exposed portion 31b of the 2nd shielded electric wire 2b and the exposed portion 31c of the 3rd shielded electric wire 2c. As shown in Figure 12 The flexible shield tube 5 can also be introduced to the joint electric cable 1 in a manner of substantially surrounding the exposed portion 31a of the 1st shielded electric wire 2a, the exposed portion 31b of the 2nd shielded electric wire 2b, and the exposed portion 31c of the 3rd shielded electric wire 2c.

[0096] Next, the 1st portion 50a of the flexible shield tube 5 is electrically (directly or indirectly) connected to the 1st shield layer 3a, and / or the 2nd portion 50b of the flexible shield tube 5 is electrically connected to both of the 2nd shield layer 3b and the 3rd shield layer 3c. Thereby, in particular, the shielding function of the flexible shield tube 5 can be achieved.

[0097] In this regard, as shown in Figure 13 According to a specific 5th process of the joint connecting method, at least one connecting member 6 is provided, the connecting member 6 is configured to mechanically and / or electrically connect the flexible shield tube 5 to the 1st shielded electric wire 2a, the 2nd shielded electric wire 2b, and / or the 3rd shielded electric wire 2c. As described above, the connecting member 6 can also have at least one 1st adhesive tape 6a and / or at least one 2nd adhesive tape 6b and / or at least one 1st binding tape and / or at least one 2nd binding tape, and / or at least one 1st clamping member and / or at least one 2nd clamping member. Figure 13 The connecting member 6 having the 1st adhesive tape 6a and the 2nd adhesive tape 6b is shown, but in the case where the connecting member 6 has a binding tape and / or a clamping member, the same steps as those described in the present specification for the adhesive tape can be used.

[0098] As shown in Figure 13 The 1st adhesive tape 6a can also be wound around at least a portion 520a of the outer surface 52 of the flexible shield tube 5 and at least a portion of the outer surface 40a of the 1st outer sheath 4a in a manner of connecting the flexible shield tube 5 to the 1st shielded electric wire 2a. In other words, by winding the adhesive tape 6a around the flexible shield tube 5 and the 1st outer sheath 4a, the flexible shield tube 5 can be connected to the 1st shielded electric wire 2a.

[0099] The second adhesive tape 6b can also be wound around at least a portion 520b of the outer surface 52 of the flexible shield tube 5, at least a portion of the outer surface 40b of the second outer jacket 4b, and at least a portion of the outer surface 40c of the third outer jacket 4c. Thus, by winding the second adhesive tape 6b around the above-mentioned portions of the joint cable 1, the flexible shield tube 5 can be mechanically connected to the second shielded electric wire 2b and the third shielded electric wire 2c.

[0100] Finally, as shown in FIG. 9, the waterproof member 9 can also be provided in accordance with a specific sixth (arbitrary) procedure of the above-mentioned joint connecting method. The waterproof member 9 can also be configured to substantially integrally surround or enclose the flexible shield tube 5 at the central portion 100c of the joint cable 1 in a manner to impart waterproofness to the joint cable 1. Figure 14

[0101] Specifically, the waterproof member 1 can also be a waterproof molded member. The waterproof member 9 can also be formed of a thermoplastic polymer or a thermosetting polymer. For example, the waterproof member 9 can also be formed of a polyvinyl chloride resin, a polyethylene resin, or a polypropylene resin, or a polyurethane resin (PUR). In particular, the waterproof member can have two or more complementary connectable shells configured to substantially surround the central portion in which the conductors of the joint cable 1 are electrically connected. As shown in FIG. 9, the two complementary connectable shells can also cover the flexible shield tube 5 that surrounds the flexible shield tube 5. Once surrounded by the waterproof member 9, the joint cable 1 is substantially waterproof. Figure 14
