Description

[Technical Field]

[0001] The present invention relates to the technical field of wiring structures, and more particularly to wiring structures having fuse assemblies and methods for manufacturing the same. [Background technology]

[0002] In prior art circuit design, circuit safety is one of the most important considerations, and circuit safety typically requires consideration of circuit protection, circuit control, and the matching of each component in the entire circuit. In the process of vehicle circuit design, fuse capacity must be determined based on the load size and electrical performance characteristics of each vehicle's electrical system, and fuse type must be determined by comprehensively considering the electrical characteristics of each electrical system and the design of the junction box. To ensure that fuses can adequately protect the circuit, circuit design must take into account issues such as the fuse's location in the circuit and the connection strength when the fuse is installed. Summary of the Invention

[0003] SUMMARY OF THE INVENTION Embodiments of the present invention provide a wiring structure with a fuse assembly that solves current fuse installation location and installation connection strength problems.

[0004] In order to solve the above technical problems, the present invention is realized as follows: In a first aspect, a wiring structure having a fuse assembly comprises a wire harness and a fuse assembly, wherein a plurality of conductors extend in parallel within the insulated wire body, and one end of the conductors in the wire harness and the insulated wire body coated on the outer periphery of one end of the conductors are cut and removed, and the fuse assembly comprises a fuse and an insulating sleeve, wherein the fuse is drilled into the insulating sleeve and one end of the fuse is welded to one end of the conductors.

[0005] In one embodiment, after one end of the conductor and the insulating wire body coated on the outer periphery of one end of the conductor are removed, a through hole is formed on the surface of the wire harness, and the one end of the conductor, the insulating wire body coated on the outer periphery of one end of the conductor, and the through hole overlap each other.

[0006] In one embodiment, one end of the conductor and the insulated wire body coated on the outer periphery of the one end of the conductor are bent and extend from one side of the through hole of the wire harness.

[0007] In one embodiment, the positions of the plurality of through holes are offset from one another in a direction perpendicular to the extension paths of the plurality of conductors.

[0008] In one embodiment, the device further comprises an insulating fixing member covering the welded portion between the fuse and the conductor.

[0009] In one embodiment, the device further includes a wiring joint connected to the other ends of the plurality of conductors.

[0010] In one embodiment, the fuse includes a first circuit conductive portion, a second circuit conductive portion, and a circuit protection portion, the circuit protection portion being located between the first circuit conductive portion and the second circuit conductive portion, the first circuit conductive portion and the second circuit conductive portion having a first line width, and the circuit protection portion having a second line width, the first line width being greater than the second line width.

[0011] In one embodiment thereof, the fuse further includes a first circuit connection portion and a second circuit connection portion, the first circuit connection portion being connected between the first circuit conductive portion and the circuit protection portion, the line width of the first circuit connection portion gradually decreasing from the first circuit conductive portion to be connected to the circuit protection portion, and the second circuit connection portion being connected between the second circuit conductive portion and the circuit protection portion, the line width of the second circuit connection portion gradually decreasing from the second circuit conductive portion to be connected to the circuit protection portion.

[0012] In one embodiment thereof, the first circuit connection portion, the second circuit connection portion, the circuit protection portion, the first circuit connection portion, and the second circuit connection portion are integrally molded.

[0013] In one embodiment, the first circuit conductive portion is welded to one end of the wire, and the second circuit conductive portion is used to connect an electronic device.

[0014] In a second aspect, a method for manufacturing a wiring structure having the fuse assembly described in the first aspect includes the steps of: preparing a wire harness in which a plurality of conductors extend in parallel within an insulated wire body; cutting one end of the conductors in the wire harness and the insulated wire body coated on the outer periphery of one end of the conductors; bending and extending one end of the conductors and the insulated wire body coated on the outer periphery of one end of the conductors outward from the wire harness; preparing a fuse assembly in which a fuse is drilled in an insulating sleeve, and welding one end of the fuse to one end of the conductor after cutting.

[0015] In one embodiment, after the step of welding one end of the fuse to one end of the conductor after cutting, an insulating fixing member is coated on the welding point between one end of the fuse assembly and one end of the conductor after cutting.

[0016] The present invention relates to a wiring structure having a fuse assembly and a manufacturing method thereof, in which one end of the conductor in the wire harness and the insulating wire body coated on the outer periphery of one end of the conductor are cut and removed, and then a fuse assembly is welded to one end of the conductor that bends and extends from inside the wire harness to the outside, thereby preventing the welding point between the fuse assembly and the conductor from being located at a position where the fuse assembly and the conductor bend and change direction.

[0017] This prevents the welding points, which have a relatively low connection strength between the fuse assembly and the conductor, from being located at stress concentration positions, reducing the likelihood of the fuse assembly and the conductor being pulled apart.

[0019] The following is a description with accompanying drawings: Several embodiments of the present invention are disclosed below by way of illustration. For clarity of explanation, many details of the implementation are described together, but it should be understood that these details of the implementation are not intended to limit the present invention.

[0020] In other words, in some embodiments of the present invention, these details are not necessarily required. In addition, in order to simplify the diagrams, some common structures and assemblies are simply and schematically shown in the diagrams. In the following embodiments, the same reference numerals indicate the same or similar assemblies.

[0021] Please refer to Figures 1 to 3. Figure 1 is a three-dimensional view of a wiring structure having a fuse assembly of the present invention, Figure 2 is an enlarged view of area A in Figure 1, and Figure 3 is an enlarged view of area B in Figure 1. As shown in the figures, the present invention provides a wiring structure 1 having a fuse assembly, which includes a wire harness 10 and a fuse assembly 20. The wire harness 10 includes a plurality of conductor wires 11 and an insulated wire body 13. The plurality of conductor wires 11 extend parallel to one another within the insulated wire body 13, and one end of the conductor wires 11 in the wire harness 10 and the insulated wire body 13 coated around the outer periphery of the one end of the conductor wire 11 are cut and removed. The fuse assembly 20 includes a fuse 201 and an insulating sleeve 202. The fuse 201 is drilled in the insulating sleeve 202, and one end of the fuse 201 is welded to one end of the conductor wire 11.

[0022] Please refer to Figures 4 and 5 together. Figure 4 is a line cross-sectional view of a wiring structure having a fuse assembly of the present invention, and Figure 5 is another cross-sectional view. As shown in the figures, in this embodiment, one end of the conductor 11 and the insulated wire 13 coated on the outer periphery of the one end of the conductor 11 are cut and removed from the surface of the wire harness 10, and then a through-hole 15 is formed on the surface of the wire harness 10, so that the one end of the conductor 11 and the insulated wire 13 coated on the outer periphery of the one end of the conductor 11 can overlap with the through-hole 15.

[0023] In other words, one end of the conductor 11 and the insulated wire 13 coated on the outer periphery of that end of the conductor 11 are taken out and bent outward from one side of the through-hole 15 of the wire harness 10. The user can set the processing position for cutting and taking out one end of the conductor 11 and the insulated wire 13 coated on the outer periphery of that end of the conductor 11 in the wire harness 10 according to the needs of use, and the through-hole 15 is located in the extension direction corresponding to the conductor 11, for example, the positions of the multiple through-holes 15 are offset from each other in a direction perpendicular to the extension path of the multiple conductors 11 in the wire harness 10 (see FIG. 5). This method makes it possible to prevent adjacent conductors 11 and adjacent fuse assemblies 20 from being affected by being too close to each other.

[0024] In addition, before welding one end of the conductor 11 in the wire harness 10 to one end of the fuse 201 in the fuse assembly 20, it is necessary to remove a portion of the insulating wire body 13 that is coated on the outer periphery of one end of the conductor 11 to expose one end of the conductor 11 outside the insulating wire body 13 (i.e., as shown in Figures 1 and 2). This makes it easier to weld the fuse 201 to one end of the conductor 11.

[0025] In this embodiment, the wiring structure 1 having the fuse assembly is constructed by cutting and removing one end of the conductor 11 in the wire harness 10 and the insulated wire body 13 coated around the outer periphery of that end of the conductor 11, and then welding the fuse assembly 20 to one end of the conductor 11 that bends and extends from inside to outside the wire harness 10, thereby preventing the welded point E between the fuse assembly 20 and the conductor 11 from being located at a position where the fuse assembly 20 and the conductor 11 bend and change direction. This prevents the welded point E, where the connection strength between the fuse assembly 20 and the conductor 11 is relatively low, from being located at a stress concentration position, and reduces the likelihood of the welded point E between the fuse assembly 20 and the conductor 11 being pulled apart.

[0026] 2 and 3, one end of a fuse 201 of the fuse assembly 20 is welded to one end of the conductive wire 11 exposed outside the through-hole 15. The fuse 201 has a first circuit conductive portion 2011, a second circuit conductive portion 2012, and a circuit protection portion 2013, the circuit protection portion 2013 being located between the first circuit conductive portion 2011 and the second circuit conductive portion 2012, the first circuit conductive portion 2011 and the second circuit conductive portion 2012 having a first line width W1, and the circuit protection portion 2013 having a second line width W2, the first line width W1 being larger than the second line width W2.

[0027] Furthermore, the fuse 201 further comprises a first circuit connecting portion 2014 and a second circuit connecting portion 2015, the first circuit connecting portion 2014 being connected between the first circuit conductive portion 2011 and the circuit protection portion 2013, with the line width of the first circuit connecting portion 2014 tapering from the first circuit conductive portion 2011 to connect to the circuit protection portion 2013, and the second circuit connecting portion 2015 being connected between the second circuit conductive portion 2012 and the circuit protection portion 2013, with the line width of the second circuit connecting portion 2015 tapering from the second circuit conductive portion 2012 to connect to the circuit protection portion 2013.

[0028] Among them, the first circuit conductive part 2011, the second circuit conductive part 2012, the circuit protection part 2013, the first circuit connecting part 2014 and the second circuit connecting part 2015 are integrally molded. The first circuit conductive part 2011 of the fuse 201 is welded to one end of the wire 11, and the second circuit conductive part 2012 of the fuse 201 is used to connect an electronic device (not shown).

[0029] See Fig. 6. In this embodiment, the wiring structure 1 having the fuse assembly further includes an insulating fastening member 17, which is coated on the welding point E between the first circuit conductive portion 2011 of the fuse 201 and the conductive wire 11.

[0030] Furthermore, since the insulating fixing member 17 can completely cover one end of the conductor 11 and one end of the fuse 201, no part of the one end of the conductor 11 or the one end of the fuse 201 is exposed to the outside, and the insulating fixing member 17 can further strengthen the connection strength of the welding point E between the fuse assembly 20 and the conductor 11. Alternatively, the insulating fixing member 17 can cover the welding point at one end of an electric wire for connecting the second circuit conductive part 2012 of the fuse 201 to an electronic device.

[0031] In addition, the wiring structure 1 with the fuse assembly further includes a wiring joint 19, which is connected to the other ends of the plurality of conductors 11. The wiring joint 19 is used to connect to a power supply device, such as an automobile power supply, and is thus used to transmit power within the conductors 11.

[0032] One end of each of the plurality of conductive wires 11 is welded to one end of a fuse assembly 20, and the other end of each of the fuse assemblies 20 is connected to an electronic device, such as a display or an automotive audio device, via an electric wire. In this way, the wiring structure 1 having the fuse assembly serves as a power supply protection structure that protects the electronic device via the fuse assembly 20. If the current strength becomes too strong, the circuit protection portion 2013 of the fuse 201 of the fuse assembly 20 cannot withstand the overcurrent and is melted by the high temperature and heat generated by the overcurrent, thus interrupting the current transmission path from the conductive wires 11 to the electronic device.

[0033] Please refer to Figure 7, which is a step diagram of the method for manufacturing a wiring structure having a fuse assembly of the present invention. As shown in the figure, in this embodiment, the steps of the method for manufacturing a wiring structure having a fuse assembly are described as follows: In step S11, a wire harness 10 in which a plurality of conductors 11 extend in parallel inside an insulated wire body 13 is prepared.

[0034] In step S12, one end of the conductor 11 in the wire harness 10 and the insulated wire 13 coated on the outer periphery of the one end of the conductor 11 are cut off. The above processing is to peel or cut off the surface of the wire harness 10 so that the one end of the conductor 11 and the insulated wire 13 coated on the outer periphery of the one end of the conductor 11 are cut off from the surface of the wire harness 10.

[0035] In step S13, one end of the conductor 11 and the insulated wire 13 coated on the outer periphery of one end of the conductor 11 are bent and extended outward from the wire harness 10. A through hole 15 is formed on the surface of the wire harness 10, and the through hole 15 is a hole through which the wire harness 10 is drilled. One end of the conductor 11 and the insulated wire 13 coated on the outer periphery of one end of the conductor 11 are bent and extended outward from one side of the through hole 15. In other words, one end of the conductor 11 bent and extending outward and the insulated wire 13 coated on the outer periphery of one end of the conductor 11 overlap each other within the through hole 15, and the remaining cut conductor 11 remains on the other side of the through hole 15.

[0036] In this embodiment, a portion of the conductor 11 is connected to the wiring joint 19, and this portion of the conductor 11 still has the power transmission function. Another portion of the conductor 11 is a line segment separated from the wiring joint 19, and the other portion of the conductor 11 and the conductor connected to the wiring joint 19 have already been disconnected from each other, so the other portion of the conductor 11 no longer has the power transmission function.

[0037] The cutting position D within the through-hole 15 where the conductor 11 is cut is located away from the wiring joint 19. In other words, a relatively long segment of the conductor 11 connected to the wiring joint 19 is left within the through-hole 15 in advance. This makes it relatively easy to later bend and pull out one end of the cut conductor 11 from within the through-hole 15 (see Figure 4). In other words, the segment of one end of the conductor 11 can be exposed outside the through-hole 15.

[0038] In step S14, a fuse assembly 20 is prepared in which a fuse 201 is inserted into an insulating sleeve 202, and one end of the fuse 201 is welded to one end of the cut conductor 11. By welding the fuse assembly 20 to the conductor 11 extending from inside to outside the wire harness 10, it is possible to prevent the welded point E between the fuse assembly 20 and the conductor 11 from being located at a position where the fuse assembly 20 and the conductor 11 are bent and change direction.

[0039] This prevents the welding point E, which has a relatively low connection strength between the fuse assembly 20 and the conductor 11, from being located at a stress concentration position, thereby reducing the situation in which the welding point E between the fuse assembly 20 and the conductor 11 is pulled apart.

[0040] In addition, step S15 is further executed after step S14. By covering the welding point E between one end of the fuse assembly 20 and one end of the cut conductor 11 with the insulating fixing member 17, the one end of the conductor 11 in the wire harness 10 and one end of the fuse 201 in the fuse assembly 20 can be completely covered with the insulating fixing member 17, and no part of the one end of the conductor 11 or the one end of the fuse 201 is exposed to the outside.

[0041] The insulating fixing member 17 can further protect the connection strength of the welding point E between the fuse assembly 20 and the conductor 11 .

[0042] In summary, the present invention relates to a wiring structure having a fuse assembly and a manufacturing method thereof, in which one end of the conductor in the wire harness and the insulating wire body coated on the outer periphery of one end of the conductor are cut and removed, and then a fuse assembly is welded to one end of the conductor that bends and extends from inside the wire harness to the outside, thereby preventing the weld point between the fuse assembly and the conductor from being located at a position where the fuse assembly and the conductor bend and change direction.

[0043] This prevents the welding points, which have a relatively low connection strength between the fuse assembly and the conductor, from being located at stress concentration positions, and reduces the likelihood of the fuse assembly and the conductor being pulled apart at the welding points.
