Description

Technical Field

[0001] This utility model relates to the field of charging harnesses, and in particular to a connector, a harness, and an electric vehicle charging harness. Background Technology

[0002] Electric vehicle charging harnesses are high-voltage cable assemblies used to connect charging equipment to the vehicle's power battery or on-board charger. They undertake the core functions of power transmission, control signal interaction, and safety protection. As a key component of the electric vehicle's high-voltage system, the charging harness uses components such as copper core wires, connectors, and insulation materials to realize the power transmission between the charging pile (or charging gun) and the vehicle battery, and simultaneously transmits signals such as charging status and fault diagnosis. Electric vehicle charging harnesses are high-voltage electrical components that integrate power transmission, signal control, and safety protection functions. Their design and performance directly affect charging efficiency and vehicle operation safety.

[0003] Because the connectors of existing charging harnesses need to be frequently connected to the charging port and exposed to the outside air, dust and impurities are easily trapped inside the connectors, affecting the safety of the interface.

[0004] Therefore, it is necessary to propose a connector, wiring harness, and electric vehicle charging wiring harness to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a connector, wire harness, and electric vehicle charging wire harness to solve the problem that the connectors of existing charging wire harnesses are prone to dust and impurities clogging the inside of the connectors due to frequent connection to the charging port and contact with the outside air, which affects the safety of the interface.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connector, including a charging head, a hand guard fixed at the lower end of the charging head, a charging interface at one end of the charging head, a first airbag fixed on the lower surface of the charging head, the first airbag being disposed inside the hand guard, a plurality of dust exhaust ports being provided inside the charging interface, and a pipe connecting the first airbag and the corresponding dust exhaust ports.

[0007] Preferably, a second airbag is fixed to one side of the top of the charging head, and a flexible tube is connected between the second airbag and the corresponding dust outlet.

[0008] Preferably, the charging interface has multiple slots on its outer side.

[0009] This utility model also discloses an electric vehicle charging harness, including a cable. The cable includes a cable sheath and a core. The core is disposed inside the cable sheath. Multiple inner cores are arranged around the outside of the core. Elastic isolation pads are disposed on the outside of the multiple inner cores. The elastic isolation pads are disposed between the inner cores and the core.

[0010] Preferably, a filler is provided between the cable sheath and the intermediate core, and between the multiple inner cores.

[0011] This utility model also discloses a wire harness, including a wear-resistant layer, which is disposed on the outer side of the cable sheath, and wear-resistant strips are fixed on the outer side of the wear-resistant layer, and multiple wear-resistant strips are provided.

[0012] Preferably, multiple wear-resistant strips are distributed along the length of the cable sheath, and a gap is left between two adjacent wear-resistant strips.

[0013] Preferably, the wear-resistant elongated cross section is configured as an isosceles trapezoid, and the lower base of the isosceles trapezoid is fixed to the cable sheath.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. A second airbag is fixed to one side of the top of the charging head. There is a flexible tube between the second airbag and the corresponding dust exhaust port. In actual operation of this utility model, the first and second airbags can be installed at the optimal position for the person to hold the charging head. When the person holds the charging head, the hand will squeeze the first and second airbags. The gas generated by the compression of the first and second airbags can be discharged from the dust exhaust port, thereby blowing and cleaning the inside of the charging interface, removing the dust inside the charging interface and preventing the dust from clogging the inside.

[0016] 2. At the same time, since the first and second airbags are elastic, they can provide a certain degree of comfort when the person holds and presses them. Furthermore, since the first and second airbags are raised, the contact area can be increased, the friction can be improved, and the hand can be prevented from slipping.

[0017] 3. In the actual operation of this utility model, by setting an elastic isolation pad, the inner core and intermediate core inside the cable sheath can be prevented from tangling with each other, thus playing an isolation role. Moreover, since the elastic isolation pad itself is elastic, even if the inner core and intermediate core are tangled to a certain extent, it can still isolate the inner core and intermediate core, preventing breakage and improving service life.

[0018] 4. In the actual operation of this utility model, by setting multiple wear-resistant strips, the friction force for personnel to pick up the cable sheath can be increased, avoiding slippage. In addition, because multiple wear-resistant strips with a certain thickness are set, when the cable is charging, it will first come into contact with the wear-resistant strips when it comes into contact with the ground, avoiding direct damage to the cable sheath and causing the inner core to be exposed.

[0023] This utility model provides, for example Figures 1-3 The connector shown includes a charging head 1, a handguard 2 fixed to the lower end of the charging head 1, and a charging interface 13 at one end of the charging head 1. The charging interface 13 can be connected to the charging port of an electric vehicle to fulfill the charging needs.

[0024] The lower surface of the charging head 1 is fixed with a first airbag 3, which is located inside the hand guard 2. The charging interface 13 has multiple dust exhaust ports 6 inside, and a pipe connects the first airbag 3 and the corresponding dust exhaust port 6.

[0025] A second airbag 4 is fixed to one side of the top of the charging head 1. There is a flexible tube between the second airbag 4 and the corresponding dust exhaust port 6. In actual operation of this utility model, the first airbag 3 and the second airbag 4 can be installed at the optimal position for the person to hold the charging head 1. When the person holds the charging head 1, the hand will squeeze the first airbag 3 and the second airbag 4. The gas generated by the squeezing of the first airbag 3 and the second airbag 4 can be discharged from the dust exhaust port 6, thereby blowing and cleaning the inside of the charging interface 13, removing the dust inside the charging interface 13 and preventing the dust from clogging the inside.

[0026] Meanwhile, since the first airbag 3 and the second airbag 4 are elastic, they can provide a certain degree of comfort when the person holds and presses them. Furthermore, since the first airbag 3 and the second airbag 4 are raised, they can increase the contact area, improve friction, and prevent the hand from slipping.

[0027] Multiple slots 5 are provided on the outside of the charging port 13, and some air can be discharged from the slots 5 to prevent dust from clogging the slots 5.

[0028] This utility model also discloses an electric vehicle charging harness, including a cable. The cable includes a cable sheath 7 and a core 10. The core 10 is disposed inside the cable sheath 7. A plurality of inner cores 9 are arranged around the outside of the core 10. An elastic isolation pad 11 is disposed on the outside of the plurality of inner cores 9. The elastic isolation pad 11 is disposed between the inner cores 9 and the core 10.

[0029] In the actual operation of this utility model, by setting the elastic isolation pad 11, the inner core 9 and the middle core 10 inside the cable sheath 7 can be prevented from getting tangled together, thus playing an isolation role. Moreover, since the elastic isolation pad 11 itself is elastic, even if the inner core 9 and the middle core 10 get tangled to a certain extent, the inner core 9 and the middle core 10 can be isolated to prevent breakage and improve service life.

[0030] Filler is provided between the cable outer sheath 7, the middle core 10, and multiple inner cores 9.

[0031] This utility model also discloses a wire harness, including a wear-resistant layer, which is disposed on the outside of the cable sheath 7, and wear-resistant strips 8 are fixed on the outside of the wear-resistant layer, and multiple wear-resistant strips 8 are provided.

[0032] Multiple wear-resistant strips 8 are distributed along the length of the cable sheath 7, and there is a gap between two adjacent wear-resistant strips 8. The cross-section of the wear-resistant strip 8 is set as an isosceles trapezoid, and the lower base of the isosceles trapezoid is fixed to the cable sheath 7.

[0033] In the actual operation of this utility model, by setting multiple wear-resistant strips 8, the friction of personnel picking up the cable sheath 7 can be increased, avoiding slippage. Also, because multiple wear-resistant strips 8 with a certain thickness are set, when the cable is charging, it will first come into contact with the wear-resistant strips 8 when it comes into contact with the ground, avoiding direct damage to the cable sheath 7 and causing the inner core 9 to be exposed.
