Description

Technical Field

[0001] The present invention relates to a composite harness for vehicles.

[0002] Background Art Conventionally, it has been known that all vehicles usually use wheel speed sensors. A wheel speed sensor is a sensor that measures the rotational speed of a wheel, and its sensor unit (sensor probe) is provided near the wheel. The sensor unit provided near the wheel and the control device (ABS (antilock braking system) electronic control device) provided on the vehicle body side are used for cable connection for the wheel speed sensor.

[0003] In recent years, electric brakes that control brakes using electric power instead of hydraulic pressure have been gradually spreading. Furthermore, an electric parking brake (EPB) in which the parking brake is electrified is widely known. In the electric parking brake, a brake caliper (drive device) provided on the wheel and a control device provided on the vehicle body side are connected using an electric brake cable.

[0004] However, conventionally, the cable for the wheel speed sensor and the cable for the electric brake have been laid separately even if their connection destinations are at almost the same position. Since the wiring space of the vehicle is limited and the wiring work is complicated, improvement is desired. In order to improve such a situation, a composite harness that wraps a plurality of cables using a harness casing has been provided, but the production and manufacturing costs of such a composite harness are high.

[0005] Summary of the Invention An object of the present invention is to provide a composite harness that can easily perform wiring work.

[0006] For this purpose, according to one aspect of the present application, a composite harness is provided, comprising a first cable, a second cable, and a cable fixing component shared by the first and second cables, wherein at least portions of the first and second cables are fixed together in parallel and fixed to a vehicle body, and connectors and / or sensor portions are provided at the ends of the first and second cables, the first cable comprising a first wire covering a first cable fixing sheath of the first wire, the second cable comprising a second wire covering a second cable fixing sheath of the second wire, and the cable fixing component comprising a body and a locking portion, the locking portion being an unsealed ring extending from the body and at least partially surrounding the first and second cables, the end of the locking portion being bent upon external force and then fixingly locking the first and second cables therein.

[0007] The above and other features and advantages of the present invention will be better understood from embodiments of the invention described below with reference to the drawings. [Brief explanation of the drawing]

[Figure 7] This is a partially enlarged schematic diagram of a composite harness according to a further embodiment of the present invention.

[0009] Modes for carrying out the invention A composite harness according to a preferred embodiment of the present invention will be described below with reference to the drawings.

[0010] Referring to Figures 1 and 2, a composite harness 1 according to one embodiment of the present invention includes a first cable 2, a second cable 3, and a cable fixing component 7 shared by the first and second cables 2 and 3, wherein at least a portion of the first cable 2 and the second cable 3 are fixed together in parallel by the cable fixing component 7 and are fixed to the vehicle body of the composite harness 1, and connectors and / or sensor parts are provided at the ends of the first cable 2 and the second cable 3. In this embodiment, the first cable 2 is a wheel speed sensor cable for transmitting signals to the vehicle's anti-lock braking system or vehicle stability control system. The second cable 3 is an electric brake cable and is mainly used as a conductive circuit through which current flows for a mechanism (electric parking brake (EPB) mechanism) that suppresses wheel rotation by pressing a predetermined button after the vehicle has stopped to function. In other embodiments, the first cable 2 and the second cable 3 may be any automotive cables.

[0011] Referring to Figure 2, the first cable 2 includes a first wire 20 and a first cable fixing sheath 21 covering the first wire 20, the first wire 20 including a central conductor (not shown) and an insulating coating (not indicated) covering the central conductor (not shown). The material of the insulating coating may be any rubbery material used for automotive wires. One end of the first cable 2 is connected to a sensor unit (sensor probe) 201, and the other end is connected to a connector 202, which is connected to a connector 202 for connection to a vehicle control unit (not shown).

[0012] The first cable fixing sheath 21 is fitted to the outside of the insulating coating of the first electric wire 20. In this embodiment, the first cable fixing sheath 21 is formed on the outside of the insulating coating of the first electric wire 20 using injection molding or extrusion molding, and the first cable fixing sheath 21 is in at least partial contact with the first cable 2, and the first cable fixing sheath 21 is made of a rubber-like material having the same or similar structure as the insulating coating of the first electric wire 20, and when the first cable fixing sheath 21 is formed around the insulating coating of the first electric wire 20, the insulating coating of the first electric wire 20 is melted by heat, thereby at least partially welding the insulating coating of the first electric wire 20 to the first cable fixing sheath 21. Therefore, the first cable fixing sheath 21 can firmly enclose the first electric wire 20 so that the first electric wire 20 does not detach and jump out of the first cable fixing sheath 21 during use. Optionally, a first retaining portion 22 for engaging with a cable fixing component 7 is provided on the first cable fixing sheath 21. In this embodiment, the first retaining portion 22 is a retaining groove formed along the outer circumferential surface of the first cable fixing sheath 21, which is used for engaging with the cable fixing component 7, and first positioning stop walls 23 formed protruding from both sides of the retaining groove are used to restrict the cable fixing component 7 within the retaining groove.

[0013] The second cable 3 includes a second wire 30 and a second cable fixing sheath 31 covering the second wire 30, the second wire 30 including a central conductor (not shown) and an insulating coating covering the central conductor. The insulating coating material may be any insulating coating used for automotive wires. One end of the second cable 3 is connected to a connector 301 and the other end is connected to a connector 302.

[0014] The second cable fixing sheath 31 is fitted to the outside of the insulating coating of the second electric wire 30. In this embodiment, the second cable fixing sheath 31 is formed on the outside of the insulating coating of the second electric wire 30 using injection molding or extrusion molding, and the second cable fixing sheath 31 is in at least partial contact with the first cable 3, and the second cable fixing sheath 31 is made of a rubber-like material having the same or similar structure as the insulating coating of the second electric wire 30, and when the second cable fixing sheath 31 is formed around the insulating coating of the second electric wire 30, the insulating coating of the second electric wire 30 is melted by heat, thereby at least partially welding the insulating coating of the second electric wire 30 to the second cable fixing sheath 31. Therefore, the second cable fixing sheath 31 can firmly surround the second electric wire 30 so that the second electric wire 30 does not detach from the second cable fixing sheath 31 and spring out during use. Optionally, a second retaining portion 32 for engaging with a cable fixing component 7 is provided on the second cable fixing sheath 31. In this embodiment, the second retaining portion 32 is a retaining groove formed along the outer circumferential surface of the second cable fixing sheath 31, which is used for engaging with the cable fixing component 7, and second positioning stop walls 33 formed protruding from both sides of the retaining groove are used to restrict the cable fixing component 7 within the retaining groove.

[0015] Referring to Figures 2 and 3 in combination, the cable fixing component 7 fixes the first cable 2 and the second cable 3 so that the second cable 3 and the first cable 2 are at least partially parallel and are arranged so that the first cable 2 and the second cable 3 are either in contact with each other or not. The cable fixing component 7 is made of a metal piece material and includes a body 70 and a locking portion 71, the locking portion 71 being an unsealed ring extending from the body 70 for at least partially surrounding the first cable 2 and / or the second cable 3, the ends of which, after being subjected to external force to form a curve, fix the first cable 2 and the second cable 3 therein. The locking portion 71 has an arc shape that at least partially corresponds to the outer arc shape of the first cable 2 and / or the second cable 3. The locking portion 71 has a width approximately equal to the width of the fastening portions 22, 32.

[0016] In this embodiment, the locking portion 71 includes a first hook portion 712 and a second hook portion 713 extending from the main body 70, the first hook portion 712 and the second hook portion 713 being bent in different directions to form semi-ring shapes for locking the first cable (2) and the second cable (3), respectively. For example, the first hook portion 712 extends from the main body 70 in a first direction, and the second hook portion 713 extends from the main body 70 in a second direction opposite to the first direction, the arc shape of the first hook portion 712 corresponds at least partially to the outer arc shape of the first fastening portion 22 of the first cable 2, the end of the first hook portion 712, after being curved, to fix the first cable 2 therein, the width of the first hook portion 712 is approximately equal to the width of the first fastening portion 22, and the first cable 2 is fixed within the first fastening portion 22. The arc shape of the second hook portion 713 corresponds at least partially to the outer arc shape of the second cable 3, and the end of the second hook portion 713, after being curved, securely locks the second cable 3 therein. There are two second hook portions 713, and the distance between the furthest side edges 713a and 713b between the two second hook portions 713 is approximately equal to the width of the second fastening portion 32, and the second cable 3 is fixed within the second fastening portion 32. When the cable fixing component 7 is viewed from above, the two second hook portions 713 and the first hook portion 712 form a three-vertex relationship of a triangle, so as to more firmly fix the cable fixing component 7 on the first cable 2 and the second cable 3, and the plane in which the triangle is located is approximately perpendicular to the plane in which the main body 70 is located. In other embodiments, the plane in which the triangle is located does not have to be perpendicular to the plane in which the main body 70 is located. The number of the first hanging parts 712 and / or the second hanging parts 713 can be increased or decreased as needed.

[0017] Referring to Figures 4 to 6, the differences between the composite harness of this embodiment and the composite harness shown in Figures 1 to 3 lie in the first cable fixing sheath 21, the second cable fixing sheath 31, and the locking portion 71. Specifically, the first cable fixing sheath 21 and the second cable fixing sheath 31 are fitted to the outside of the insulating coatings of the first wire 20 and the second wire 30, respectively, by an attachment method. There are no first fastening portions 22 and second fastening portions 32, and the locking portion 71 provides frictional force by being pushed out to hold the first sheath 21 and the second sheath 31 on the first wire 20 and the second wire 30, respectively. The locking portion 71 includes a continuously formed first arc-shaped portion 714, a second arc-shaped portion 715, and a curved portion 716. The first arc-shaped portion 714 and the second arc-shaped portion 715 are used to prevent the first cable 2 and the second cable 3 from swinging around within the locking portion 71, and the arcs of the first arc-shaped portion 714 and the second arc-shaped portion 715 are oriented in the same direction, the arc of the first arc-shaped portion 714 corresponds at least partially to the outer arc of the first cable fixing sheath 21 after the first cable 2 has been pushed out, and the first cable fixing sheath 21 is used to house the first cable 2 therein, the arc of the second arc-shaped portion 715 corresponds at least partially to the outer arc of the second cable fixing sheath 31 after it has been pushed out, and the second cable fixing sheath 31 is used to house the second cable 3 therein, and the curved portion 716 is located at the end of the locking portion 71 and, after being curved, fixably locks the first cable 2 and the second cable 3 together within the locking portion 71. After the curved portion 716 is curved, it forms at least partially an arc shape, which at least partially corresponds to the outer circumferential arc shape of the first cable fixing sheath 21 and / or the second cable fixing sheath 31.

[0018] To reiterate, although not mentioned in the embodiments described above, it goes without saying that it is also possible to combine wires other than the first cable 2 and the second cable 3 into one. For example, referring to Figure 7, the composite harness 1 includes a third cable 4, and the cable fixing component 7 fixes at least a portion of the first cable 2, the second cable 3, and the third cable 4 together in parallel, and the types of the first cable 2, the second cable 3, and the third cable 4 may or may not be the same.

[0019] Therefore, by using the cable fixing component 7 to combine at least two separately formed cables into one, production costs are reduced, and the wiring space in the vehicle can be used effectively, making wiring and installation work easier.

[0020] While specific embodiments of the present invention have been described, they are merely illustrative and do not limit the scope of the invention. On the contrary, the structures described herein can be embodied in various other forms, and various substitutions and modifications can be made to the structural forms described herein, provided that they do not depart from the spirit and scope of the invention.
