Description

Technical Field

[0001] This disclosure relates to the field of automotive wiring harness technology, and in particular to an integrated automotive power and audio transmission structure and an automotive transmission wiring harness. Background Technology

[0002] As the "nerves" of the automotive electrical system, the vehicle power harness is important in several key aspects, directly affecting the vehicle's safety, reliability, and functionality.

[0003] Current automotive power wiring harnesses use multi-pin connectors, automotive power supply lines, and power terminals to connect the battery to the vehicle's central control system. Typically, a single power supply line is divided into multiple conductors for power distribution to meet the power needs of various components within the vehicle. Some companies also integrate the power supply and audio components into a single transmission harness; similarly, the power supply section in this harness also divides a single power supply line into multiple conductors.

[0004] However, when a single power supply line is divided into multiple conductors, if the multiple conductors are not on the same horizontal plane, that is, if the multiple conductors are not linearly arranged in cross-section, it will lead to a messy wiring harness layout. Furthermore, if multiple conductors are bundled together, there will be friction between multiple conductors near the shunt terminal, which will cause wear on the insulation layer of the conductors, affect the service life of the conductors, and consequently lead to unstable power supply to various components in the vehicle's central control system. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an integrated vehicle power audio transmission structure and vehicle transmission harness that enables the conductors to be linearly distributed in cross-section and effectively reduces the friction between multiple conductors.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] An integrated vehicle power and audio transmission structure includes a power plug, a power supply cable assembly, and an audio power supply cable assembly. Both the power supply cable assembly and the audio power supply cable assembly are electrically connected to the power plug. The power supply cable assembly includes a positive power supply component, a power supply grounding component, and a power supply terminal. The positive power supply component includes a positive power supply line, a positive branching component, and X positive wires. The positive branching component includes a positive electrode coating block, a positive electrode shunt terminal, a positive electrode coating film, and X-1 positive electrode branching pieces. The positive electrode shunt terminal is electrically connected to the positive power supply line and the X positive wires, respectively. The X positive wires and X-1 positive electrode branching pieces are alternately arranged. The positive electrode coating film covers the positive electrode shunt terminal, the X positive wires, and the X-1 positive electrode branching pieces, so that the X positive wires and X-1 positive electrode branching pieces are arranged in a straight line in cross-section. The positive electrode coating... The positive electrode coating film is covered by a block; the power supply grounding component includes a negative electrode wire, a negative electrode branching component, and Y negative electrode wires. The negative electrode branching component includes a negative electrode coated block, a negative electrode shunt terminal, a negative electrode coating film, and Y-1 negative electrode branching pieces. The negative electrode shunt terminal is electrically connected to the negative electrode wire and the Y negative electrode wires respectively. The Y negative electrode wires and the Y-1 negative electrode wires and the Y-1 negative electrode branching pieces are alternately arranged. The negative electrode coating film covers the positive electrode coating film. The device comprises a negative shunt terminal, Y negative wires, and Y-1 negative wire dividers, such that the Y negative wires and Y-1 negative wire dividers are arranged in a straight line in cross-section. The negative electrode coating block covers the negative electrode coating film. The positive power supply line and the negative wire are both electrically connected to the power supply plug. X positive wires and Y negative wires are both electrically connected to the power supply terminal, where X and Y are natural numbers, and X≥2, Y≥2.

[0008] In one embodiment, the number of positive conductors is equal to the number of negative conductors.

[0009] In one embodiment, the number of positive electrode separators is equal to the number of negative electrode separators.

[0010] In one embodiment, the power supply positive terminal component further includes a fuse, which is disposed on the positive power supply line so that the fuse is electrically conductive when the power supply line assembly is energized.

[0011] In one embodiment, the fuse includes a mounting base, a fuse terminal, and a fuse pin. The mounting base is sleeved on the outside of the positive power supply line. The mounting base has a power receiving groove. The fuse terminal is located in the power receiving groove and is electrically connected to the positive power supply line. The fuse pin is electrically connected to the fuse terminal.

[0012] In one embodiment, the mounting base is an insulating rubber mounting base.

[0013] In one embodiment, the audio power supply cable assembly includes an audio power terminal and a plurality of audio wires, one end of each of the plurality of audio wires being electrically connected to the power supply plug, and the other end of each of the plurality of audio wires being electrically connected to the audio power terminal.

[0014] In one embodiment, the length of the audio cable is 40cm-42cm.

[0015] In one embodiment, the power plug is a one-piece molded structure.

[0016] An in-vehicle transmission harness includes an integrated in-vehicle power and audio transmission structure as described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] The current from the positive power supply line is shunted after passing through the positive shunt terminal and then flows through multiple positive wires. When assembling the positive power supply component, adjacent positive wires are separated by a positive wire divider to alternate between the positive wires and the positive wire divider, reducing friction between adjacent wires and ensuring the lifespan of subsequent products. The positive shunt terminal, positive wires, and positive wire divider are then covered with a positive coating film, making the positive wires and positive wire divider linearly distributed in cross-section. Finally, after injection molding, a positive coated block is formed. At this point, the multiple positive wires are linearly distributed, appearing orderly and neat, without interference or friction between adjacent wires. Similarly, the same effect is used when assembling the power supply grounding component. After assembly, the multiple negative wires are also linearly distributed, ensuring that the vehicle's central control system can be powered normally. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] Please see Figure 1 The vehicle-mounted power and audio integrated transmission structure 10, which is an embodiment of the present utility model, includes a power plug 100, a power supply line assembly 200 and an audio power supply line assembly 300, and the power supply line assembly 200 and the audio power supply line assembly 300 are electrically connected to the power plug 100.

[0034] like Figures 2 to 4 As shown, the power supply cable assembly 200 includes a positive power supply component 210, a power supply grounding component 220, and a power supply terminal 230. The positive power supply component 210 includes a positive power supply line 211, a positive branching component 212, and X positive wires 213. The positive branching component 212 includes a positive coating block 2121, a positive shunt terminal 2122, a positive coating film 2123, and X-1 positive branching pieces 2124. The shunt terminal 2122 is electrically connected to the positive power supply line 211 and X positive wires 213 respectively. The X positive wires 213 and X-1 positive branch plates 2124 are alternately arranged. The positive coating film 2123 covers the positive shunt terminal 2122, the X positive wires 213 and X-1 positive branch plates 2124, so that the X positive wires 213 and X-1 positive branch plates 2124 are arranged in a straight line in cross-section. The effect diagram is shown below. Figure 5 As shown, the positive electrode coating block 2121 covers the positive electrode coating film 2123. Specifically, the positive electrode coating film 2123 covers the portion of X positive electrode wires 213 adjacent to the positive electrode shunt terminal 2122.

[0035] like Figure 2 , Figure 6 and Figure 7As shown, the power supply grounding component 220 includes a negative wire 221, a negative wire splitter 222, and Y negative wires 223. The negative wire splitter 222 includes a negative insulated block 2221, a negative shunt terminal 2222, a negative coating film 2223, and Y-1 negative wire split pieces 2224. The negative shunt terminal 2222 is electrically connected to the negative wire 221 and the Y negative wires 223 respectively. The Y negative wires 223 and the Y-1 negative wires 223 and the Y-1 negative wire split pieces 2224 are alternately arranged. The negative coating film 2223 covers the negative shunt terminal 2222, the Y negative wires 223, and the Y-1 negative wire split pieces 2224 so that the Y negative wires 223 and the Y-1 negative wire split pieces 2224 are arranged in a straight line in cross-section. The effect is shown in the figure below. Figure 8 As shown, the negative electrode coating block 2221 covers the negative electrode coating film 2223. Specifically, the negative electrode coating film 2223 covers the portion of Y negative electrode wires 223 adjacent to the negative electrode shunt terminal 2222. The positive electrode power supply line 211 and the negative electrode line 221 are both electrically connected to the power supply plug 100. X positive electrode wires 213 and Y negative electrode wires 223 are both electrically connected to the power supply terminal 230, where X and Y are natural numbers, and X≥2 and Y≥2.

[0036] It can be understood that a positive electrode splitter 2124 is added between two adjacent positive electrode conductors 213, and so on, forming a row with X positive electrode conductors 213 and X-1 positive electrode splitter 2124. For example, when X=5, a row of structures forms 5 positive electrode conductors 213 and 4 positive electrode splitter 2124, and the positive electrode conductors 213 and positive electrode splitter 2124 are arranged alternately. Similarly, a negative electrode splitter 2224 is added between two adjacent negative electrode conductors 223, forming a row with Y negative electrode conductors 223 and Y-1 negative electrode splitter 2224. For example, when Y=5, a row of structures forms 5 negative electrode conductors 223 and 4 negative electrode splitter 2224, and the negative electrode conductors 223 and negative electrode splitter 2224 are arranged alternately.

[0037] In another embodiment, the positive electrode separator 2124 and the negative electrode separator 2224 are made of insulating materials, such as rubber or nylon; the positive electrode coating film 2123 and the negative electrode coating film 2223 are both made of insulating materials, such as polypropylene.

[0038] In the above embodiment, the current passing through the positive power supply line 211 is shunt after passing through the positive shunt terminal 2122 and then through multiple positive wires 213. When assembling the power supply positive component 210, adjacent positive wires 213 are separated by a positive wire divider 2124, so that the positive wires 213 and the positive wire divider 2124 are alternately arranged to reduce the friction between adjacent wires and ensure the service life of subsequent products. Then, the positive shunt terminal 2122 and the positive wires are covered by the positive coating film 2123. The positive conductor 213 and the positive electrode splitter 2124 are covered, so that the positive conductor 213 and the positive electrode splitter 2124 are linearly distributed in cross-section. After injection molding, the positive electrode encapsulated block 2121 is formed. At this time, the multiple positive conductors 213 are linearly distributed, appearing orderly and neat, and there is no interference or friction between adjacent conductors. Similarly, when assembling the power supply grounding component 220, the same effect is adopted. After the assembly is completed, the multiple negative conductors 223 are also linearly distributed, which can ensure that the vehicle central control can be powered normally.

[0039] In this embodiment, the number of positive wires 213 is equal to the number of negative wires 223, so that a circuit can be formed when current passes through a single positive wire 213 and a single negative wire 223, ensuring that the vehicle central control system can operate normally. Furthermore, the number of positive terminal blocks 2124 is equal to the number of negative terminal blocks 2224, so that there is always a positive terminal block 2124 between any two adjacent positive wires 213, and there is always a negative terminal block 2224 between any two adjacent negative wires 223. Given that the number of positive wires 213 is equal to the number of negative wires 223, the number of positive terminal blocks 2124 should also be equal to the number of negative terminal blocks 2224.

[0040] like Figure 2As shown, in one embodiment, the positive power supply component 210 further includes a fuse 214, which is disposed on the positive power supply line 211 so that the fuse 214 is electrically conductive when the power supply line assembly 200 is energized. Further, the fuse 214 includes a mounting base 2141, a fuse terminal (not shown), and a fuse pin 2142. The mounting base 2141 is sleeved on the outside of the positive power supply line 211, and the mounting base 2141 has a contact groove (not shown). The fuse terminal is located in the contact groove and is electrically connected to the positive power supply line 211. The fuse pin 2142 is electrically connected to the fuse terminal. It is understood that when the power plug 100 and power supply terminal 230 are connected, the vehicle central control system can only be powered on when the fuse pin 2142 and the fuse terminal are electrically connected. If the current passing through the fuse pin 2142 is too large, such as in the event of a short circuit, overcurrent, or overvoltage, the temperature of the fuse itself will rise, reaching the condition for melting, thereby immediately disconnecting the vehicle central control system to prevent damage and ensure its safe use. In this embodiment, the mounting base 2141 is an insulating rubber mounting base 2141. Furthermore, the fuse terminal is electrically connected to the conductive part inside the positive power supply line 211.

[0041] like Figure 1 As shown, in one embodiment, the audio power supply cable assembly 300 includes an audio power terminal 320 and a plurality of audio wires 310. One end of each of the plurality of audio wires 310 is electrically connected to the power supply plug 100, and the other end of each of the plurality of audio wires 310 is electrically connected to the audio power terminal 320. When the power supply plug 100 and the audio power terminal 320 are respectively connected to the car battery and the car audio system, the audio signal can be transmitted through each audio wire 310 so that the car audio system can operate normally.

[0042] In one embodiment, the audio cable 310 is 40cm-42cm long. In this embodiment, the audio cable 310 is 40cm long.

[0043] In one embodiment, the power plug 100 is a one-piece molded structure. When manufacturing the power plug 100, the power plug 100 is made according to the shape of the injection mold, and it only needs to be molded once, without the need for secondary processing, thus saving time and cost in producing the power plug 100.

[0044] This disclosure also provides an in-vehicle transmission harness, including the in-vehicle power and audio integrated transmission structure 10 of any of the above embodiments.

[0045] Compared with the prior art, this disclosure has at least the following advantages:

[0046] The current flowing through the positive power supply line 211 is shunt after passing through the positive shunt terminal 2122 and then through multiple positive wires 213. When assembling the power supply positive component 210, adjacent positive wires 213 are separated by a positive wire divider 2124, so that the positive wires 213 and the positive wire divider 2124 are alternately arranged to reduce the friction between adjacent wires and ensure the service life of subsequent products. Then, the positive shunt terminal 2122 and the positive wires 213 are covered by the positive coating film 2123. The positive electrode wire 213 and the positive electrode wire 2124 are covered together, so that the positive electrode wire 213 and the positive electrode wire 2124 are distributed in a straight line in cross-section. Finally, after injection molding, a positive electrode encapsulated block 2121 is formed. At this time, the multiple positive electrode wires 213 are distributed in a straight line, which appears orderly and neat, and there is no interference or friction between adjacent wires. Similarly, when assembling the power supply grounding component 220, the same effect is adopted. After the assembly is completed, the multiple negative electrode wires 223 are also distributed in a straight line, which can ensure that the vehicle central control can be powered normally.

[0047] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
