[0022] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] In the description of the utility model, it needs to explain, the term "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and so on indicate the orientation or position relation based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and cannot indicate or imply that the indicated device or element must have a specific orientation, a specific orientation and operation, therefore cannot be understood as the limitation of the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the utility model, it needs to explain, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0025] The utility model discloses a shielding sleeve, such as Figure 1 And Figure 2 As shown, the shielding sleeve includes the pipe body 1. Specifically, the pipe body 1 includes a plurality of metal wires 2 distributed along the warp, a plurality of textile filaments 3 distributed along the weft, and each metal wire 2 and each textile filament 3 are alternately and vertically interlaced to form the pipe body 1. That is, as shown in Figure 1 Each metal wire 2 and each textile filament 3 are cross-interlaced by a horse interlacing machine. Taking the interlacing method between two adjacent metal wires 2 and a single textile filament 3 as an example, the two adjacent metal wires 2 are arranged on both sides of the textile filament 3. The interlacing between two adjacent textile filaments 3 and a single metal wire 2 is the same, and the two adjacent textile filaments 3 are arranged on both sides of the metal wire 2. Therefore, after the plurality of metal wires 2 distributed along the warp and the plurality of textile filaments 3 distributed along the weft are interlaced, a mesh surface is formed, which can be regarded as being composed of a plurality of adjacent cubic blocks, each cubic block is composed of small metal wires 2 and small textile filaments 3, and the positions of the small metal wires 2 and the small textile filaments 3 between two adjacent cubic blocks are opposite. After the two ends of the mesh surface are connected to each other, the pipe body 1 in the form of a circular tube is formed.

[0026] The main improvement of the utility model lies in that the pipe body 1 further includes a grounding wire 4, and the metal wire 2, the textile filament 3 and the grounding wire 4 are interlaced together during the interlacing process of the pipe body 1. Specifically, as shown in Figure 2As shown, the grounding wire 4 passes through each adjacent metal wire 2 and each textile wire 3 in turn. Between each adjacent textile wire 3, when the grounding wire 4 passes through the current textile wire 3, the grounding wire 4 is arranged on the side of the current textile wire 3 away from the metal wire 2, that is, the grounding wire 4 passes through the side of the current textile wire 3 away from the metal wire 2, or the grounding wire 4 is arranged on the side of the current metal wire 2 away from the textile wire 3, that is, the grounding wire 4 passes through the side of the current metal wire 2 away from the textile wire 3; then when the grounding wire 4 passes through the adjacent textile wire 3, the grounding wire 4 is located between the adjacent metal wire 2 and the textile wire 3, that is, the grounding wire 4 passes through between the adjacent metal wire 2 and the textile wire 3.

[0027] The weaving method of the pipe body 1 including the grounding wire 4 can also be that the grounding wire 4 always passes through between each metal wire 2 and each textile wire 3. Compared with the pipe body 1 woven by the above method, the pipe body 1 woven by this method has more closely combined grounding wire 4 and each metal wire 2 and each textile wire 3, but the weaving difficulty is greater than that of the above method.

[0028] The utility model discloses a grounding wire 4 is woven in the metal wire 2 and the textile wire 3, so that the shielding sleeve of the utility model has better electromagnetic shielding performance and flexibility, and the shielding sleeve has better wear resistance, and the grounding wire 4 is not easy to damage.

[0029] The shielding sleeve of the utility model has multiple implementation manners for the structure of the metal wire 2, the structure of the textile wire 3, the structure of the grounding wire 4 and other technical features, and the following will be described in detail for one of the implementation manners of the structure of the grounding wire 4 and other technical features, and the implementation example of the implementation manner is called the present embodiment. The other implementation manners of the multiple features are called other embodiments, and the following will be briefly described for the other embodiments.

[0030] In the present embodiment, as shown in Figure 2 The grounding wire 4 extends out of the end of the pipe body 1, that is, the grounding wire 4 has a grounding wire protruding portion relative to one end of the pipe body 1. The utility model discloses that the grounding wire 4 extends out of the end of the pipe body 1, so that the grounding wire 4 protruding from one end of the pipe body 1 is convenient for connecting with the automobile frame, that is, the grounding wire 4 is convenient for grounding. In other embodiments, a bus ring can also be installed on one end of the pipe body 1, and the grounding wire 4 is electrically connected with the bus ring, and the automobile wire harness enters the pipe body 1 after passing through the bus ring.

[0031] In the present embodiment, as shown in Figure 2As shown, the shielding sleeve further comprises a grounding clamp 5, and one end of the grounding wire 4 extending out of the pipe body 1 is connected with the grounding clamp 5. Through the arrangement of the grounding clamp 5, the grounding clamp 5 can be clamped on the automobile frame, and the connection of the grounding wire 4 and the automobile frame is facilitated. In other embodiments, the grounding clamp 5 can be replaced by a grounding magnetic block, and the magnetic block is adsorbed on the steel frame to achieve the effect of connecting the grounding wire 4 and the frame.

[0032] In the embodiment, as shown, Figure 1 The grounding wire 4 is arranged along the axis direction of the pipe body 1. Therefore, the grounding wire 4 has good supportability to the pipe body 1, effectively increases the strength of the pipe body 1, and thus the material of the metal wire 2 and the textile wire 3 can be reduced, that is, the decitex value of the metal wire 2 and the textile wire 3 can be reduced. In other embodiments, the grounding wire 4 can also be spirally arranged around the pipe body 1.

[0033] In the embodiment, two grounding wires 4 are arranged, and each grounding wire 4 is symmetrically arranged relative to the axis of the pipe body 1. The number of the grounding wires 4 is not more the better, and the arrangement of more grounding wires 4 will make the pipe body 1 difficult to bend. The present application takes into account the strength of the pipe body 1 while facilitating the bending of the pipe body 1 through the symmetrically arranged grounding wires 4. In other embodiments, the number of the grounding wires 4 can also be three, and each grounding wire 4 is arranged at equal intervals along the circumference of the pipe body 1.

[0034] In the embodiment, the larger the diameter of the electric wire, the larger the area through which the current passes, and thus the current can more easily pass through the electric wire. Therefore, the grounding wire 4 needs to have good conductivity, and thus the diameter of the grounding wire 4 needs to be greater than the diameter of the metal wire 2. However, if the diameter of the grounding wire 4 is too large, the bending performance of the pipe body 1 will be affected. Specifically, the diameter of the grounding wire 4 is one and a half times to two times the diameter of the metal wire 2. The present application limits the diameter of the grounding wire 4 to ensure the conductivity of the grounding wire 4 while taking into account the bending performance of the pipe body 1. In other embodiments, according to the size of the current during the working process of the automobile wire harness wrapped in the pipe body 1, a grounding wire 4 with a larger diameter or a grounding wire 4 with a smaller diameter can be selected, that is, the diameter of the grounding wire 4 can be more than twice the diameter of the metal wire 2, or the diameter of the grounding wire 4 can be 1.1 times to 1.5 times the diameter of the metal wire 2.

[0035] In the embodiment, the metal wire 2 and the grounding wire 4 are both multifilament, that is, both are twisted from a plurality of metal filaments. Specifically, any one or more of copper-clad aluminum wire, tinned copper wire, nickel-plated copper wire, and silver-plated copper wire can be twisted.

[0036] In the utility model, the textile silk 3 is any one or multiple combinations of PET multifilament, PPS multifilament, PEEK multifilament, PA multifilament and PE multifilament. In the embodiment, the textile silk 3 is PET multifilament, and the PET multifilament is made of twisted polyester monofilament, and the diameter of the polyester monofilament is 0.18-0.38 mm. Specifically, the diameter of the polyester monofilament can be 0.18 mm or 0.20 mm or 0.22 mm or 0.25 mm or 0.38 mm. In other embodiments, the textile silk 3 is PET monofilament.

[0037] In conclusion, the shielding sleeve of the utility model has good electromagnetic shielding performance and bending property, and the grounding wire 4 is not easy to be damaged. The grounding wire 4 is extended out of the end of the pipe body 1, so that the grounding wire 4 is easy to be grounded. The grounding clamp 5 is arranged, so that the grounding wire 4 is easy to be connected with the automobile frame. The grounding wire 4 is arranged along the axis direction of the pipe body 1, so that the strength of the pipe body 1 is effectively increased. The grounding wires 4 are symmetrically arranged, so that the strength of the pipe body 1 is considered, and the pipe body 1 is easy to be bent. The diameter of the grounding wire 4 is limited, so that the conductivity of the grounding wire 4 is ensured, and the bending property of the pipe body 1 is considered.

[0038] It should be emphasized that: the above is only the preferred embodiment of the utility model, and does not limit the utility model in any form, and any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model still belongs to the range of the utility model technical scheme.
