Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a domain controller gigabit Ethernet wire harness. Background Art

[0002] The automotive industry is developing rapidly, and intelligent driving technology in particular is being pursued by many automakers. However, to achieve L0-L4 driving experience, many sensors, computers, and actuators are needed in automotive hardware, which requires a large amount of data feedback, input, output, and calculation. The road conditions faced by cars are diverse, which requires extremely fast data transmission rates. The CAN bus architecture used in previous cars is far from meeting the requirements of modern cars.

[0003] Smart driving requires smart networking. Today's automotive industry is undergoing two transformation initiatives. One is the electrification of automobiles (the transition from traditional fuel vehicles to new energy vehicles), and the other is the intelligence and networking of automobiles. Networked cars have broken through the functions previously limited to GPS, car radios, car Bluetooth and WIFI connections. However, how to better serve passengers, such as parking assistance, lane departure warning, night vision assistance, adaptive cruise control, collision avoidance, blind spot detection, driver fatigue detection and other safety functions are the most important. Therefore, high-definition cameras, lidars and even millimeter-wave radars are needed for monitoring. How to feed back the monitored data to each actuator as quickly as possible and to the "cloud" background for storage requires a wiring harness to connect and transmit feedback signals. The traditional CAN line transmission rate is only 1Mbps, 100Mbps is 100Mbps, and the current DCU (Domain Control Unit domain controller) can be divided into three domains: vehicle control domain, smart cockpit domain, and smart driving domain. In particular, the integration of domain controllers (DCU) requires more and more signal feedback and calculations to be processed, while the transmission capacity of the existing 100M Ethernet harness structure is completely unable to bear the needs of DCU smart driving. The transmission rate is low, and signal frame and packet loss will occur during the transmission process. Therefore, the utility model proposes a domain controller Gigabit Ethernet harness to solve the problems existing in the prior art. Utility Model Content

[0004] In response to the above problems, the present invention proposes a domain controller Gigabit Ethernet harness, which consists of a first connector with six groups of first PIN heads, connecting multiple shielded twisted pair cables of the same length, and a second connector with a single second PIN head at the other end of the shielded twisted pair cables. The first connector can be docked with the DCU board-end connector, and the second connector can be docked with the laser radar. The number of laser radars determines the number of second connectors and shielded twisted pair cables used, thereby increasing the multiple transmission channels and improving the signal transmission rate of the Ethernet harness.

[0005] To achieve the purpose of the utility model, the utility model is implemented through the following technical solutions: a domain controller Gigabit Ethernet harness, comprising a first connector, a shielded twisted pair cable, and a second connector, wherein the shielded twisted pair cable and the second connector are provided in multiple groups, one end of each of the multiple groups of shielded twisted pair cables is connected to the first connector, and the other ends of the multiple groups of shielded twisted pair cables are respectively connected to multiple groups of the second connector;

[0006] The first connector is provided with a first PIN head, and the first PIN head has six groups. The first PIN head has two groups of first contact slots. One group of the first PIN heads is used to connect to one end of a group of the shielded twisted pair cables, and the two groups of wires inside the shielded twisted pair cables are respectively conductively connected to the two groups of first contact slots. The second connector is provided with a second PIN head, and the second PIN head has two groups of second contact slots. The second PIN head is used to connect to one end of a single group of the shielded twisted pair cables, and the two groups of wires inside the shielded twisted pair cables are respectively conductively connected to the two groups of second contact slots.

[0007] A further improvement is that: the shielded twisted pair cables are provided in at least five groups, and the second connectors are provided in at least five groups.

[0008] A further improvement is that a first function label and a product label are provided on one end of the shielded twisted pair cable close to the first connector, and the first function label corresponds to the first connector.

[0009] A further improvement is that: a second function label is provided at one end of each group of the shielded twisted pair cables close to the second connector, and multiple groups of the second function labels correspond to multiple groups of the second connectors respectively.

[0010] A further improvement is that: both ends of the shielded twisted pair are stripped to reveal the conductors, and a shielding metal ring is sleeved at the junction of the stripped ends of the shielded twisted pair.

[0011] A further improvement is that the wire is stripped to expose the copper wire, and a fixed metal block is provided on the copper wire, one end of the fixed metal block is connected to an insertion module, and the insertion module is adapted to the first contact slot and the second contact slot.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model consists of a first connector with six groups of first PIN heads, which connect multiple shielded twisted pair cables of the same length. The other end of the shielded twisted pair cables uses a second connector with a single second PIN head. The first connector can be docked with the DCU board connector, and the second connector can be docked with the laser radar. The number of second connectors and shielded twisted pair cables used determines the number of laser radars. This increases the multiple transmission channels and improves the signal transmission rate of the Ethernet harness. The connection structure based on the Ethernet connector can be universal, which helps the field of intelligent driving.

[0014] 2. According to the functions of the first connector and the second connector at both ends, the utility model can paste the first function label and the second function label on both ends of the shielded twisted pair cable respectively, which is convenient for installation and plays an error-proofing role.

Each of the first PIN connectors 4 is used to connect to one end of a shielded twisted pair cable 2, with the two groups of wires within the shielded twisted pair cable 2 electrically conductively connected to the two groups of first contact slots 5. The second connector 3 is internally provided with a second PIN connector 6, which has two groups of second contact slots 7. The second PIN connector 6 is used to connect to one end of a single shielded twisted pair cable 2, with the two groups of wires within the shielded twisted pair cable 2 electrically conductively connected to the two groups of second contact slots 7. In use, the first connector 1, having six groups of first PIN connectors 4, is connected to multiple shielded twisted pair cables 2 of equal length. The second connector 3, having a single second PIN connector 6 at the other end of the shielded twisted pair cables, comprises the first connector 1. The first connector 1 can interface with a DCU board connector, while the second connector 3 can interface with a laser radar. The number of second connectors 3 and shielded twisted pair cables 2 required is determined by the number of laser radars. This increases the number of transmission channels and improves the signal transmission rate of the Ethernet harness. The Ethernet connector's connection structure allows for universal use.

[0024] There are five groups of shielded twisted pair cables 2 and five groups of second connectors 3. The ends of the shielded twisted pair cables 2 near the first connector 1 are provided with a first function label 8 and a product label 9. The first function label 8 corresponds to the first connector 1. Each group of shielded twisted pair cables 2 has a second function label 10 at the end near the second connector 3, and multiple groups of second function labels 10 correspond to multiple groups of second connectors 3. First function labels 8 and second function labels 10 can be affixed to each end of the shielded twisted pair cables 2, depending on the functions of the first and second connectors 1 and 3 at each end, facilitating installation and preventing errors.

[0025] Example 2

[0026] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment provides a domain controller Gigabit Ethernet harness, including a first connector 1, a shielded twisted pair cable 2, and a second connector 3. The shielded twisted pair cable 2 and the second connector 3 are provided in multiple groups, one end of each of the multiple groups of shielded twisted pair cables 2 is connected to the first connector 1, and the other ends of the multiple groups of shielded twisted pair cables 2 are respectively connected to the multiple groups of second connectors 3;

[0027] The first connector 1 is internally provided with a first PIN connector 4, which has six groups. Each of the first PIN connectors 4 has two groups of first contact slots 5. Each of the first PIN connectors 4 is used to connect to one end of a shielded twisted pair cable 2, with the two groups of wires within the shielded twisted pair cable 2 electrically conductively connected to the two groups of first contact slots 5. The second connector 3 is internally provided with a second PIN connector 6, which has two groups of second contact slots 7. The second PIN connector 6 is used to connect to one end of a single shielded twisted pair cable 2, with the two groups of wires within the shielded twisted pair cable 2 electrically conductively connected to the two groups of second contact slots 7. In use, the first connector 1, having six groups of first PIN connectors 4, is connected to multiple shielded twisted pair cables 2 of equal length. The second connector 3, having a single second PIN connector 6 at the other end of the shielded twisted pair cables, comprises the first connector 1. The first connector 1 can interface with a DCU board connector, while the second connector 3 can interface with a laser radar. The number of second connectors 3 and shielded twisted pair cables 2 required is determined by the number of laser radars. This increases the number of transmission channels and improves the signal transmission rate of the Ethernet harness. The Ethernet connector's connection structure allows for universal use.

[0028] The shielded twisted pair 2 has its conductors stripped at both ends, and a shielding metal ring 11 is placed at the junction of the stripped ends. The stripped conductors expose copper wires, which are secured with a fixed metal block 12. One end of the fixed metal block 12 is connected to an insert module 13, which fits into the first and second contact slots 5 and 7. During processing, a rotary stripping machine is used to strip the insulation of the shielded twisted pair cable 2 to expose the copper wire in the wire, and the shielding layer is pre-processed at the same time. The terminal crimping machine is used to crimp the terminal and the shielding metal ring 11, and the crimped terminal is assembled into the insertion module 13. The crimping mold is used again to crimp the fixed metal block 12 first, and finally the crimped semi-finished product is assembled into the contact groove of the connector according to the connector PIN position sequence. According to the function of the connector assembly at both ends, functional labels are affixed to both ends of the wiring harness for easy installation and error prevention. Finally, when the wiring harness is provided to the DCU (domain controller) or laser radar manufacturer, it can be directly installed and used. The 6-PIN first connector 1 is connected to the DCU board-end connector, and the single-PIN second connector 3 is connected to the laser radar (the number of single-PIN connectors used determines the number of laser radars).

[0029] The domain controller Gigabit Ethernet harness consists of a first connector 1 with six groups of first PIN heads 4, connecting multiple shielded twisted pair cables 2 of the same length, and a second connector 3 with a single second PIN head 6 at the other end of the shielded twisted pair cable 2. The first connector 1 can be docked with the DCU board-end connector, and the second connector 3 can be docked with the laser radar. The number of laser radars determines the number of second connectors 3 and shielded twisted pair cables 2 used, thereby increasing the multiple transmission channels and improving the signal transmission rate of the Ethernet harness. The connection structure based on the Ethernet connector can be universal, assisting the field of intelligent driving, and according to the functions of the first connector 1 and the second connector 3 at both ends, the first function label 8 and the second function label 10 can be respectively affixed to both ends of the shielded twisted pair cable 2, which is convenient for installation and has an error-proof effect.
