Description of material scheme of AC charging gun and charging socket

With the emerging of electric vehicle industry, charging pile Charging gun And other new markets and opportunities are also rising. Charging is divided into DC charging and AC charging Charging gun It is a common charging equipment at present, and the AC charging socket has the requirements of flame retardant, weather resistance and high temperature resistance in material selection. Therefore, pet and PA66 meet the requirements.

1、 Communication Charging gun Choice of

1. High CTI (leakage trace index): 400gti ≥ 250V to ensure no leakage and power safety.

2. Excellent weather resistance, can be used outdoors for a long time.

3. Super low temperature toughness (- 40 ℃ can maintain good impact), which can be used in most domestic climate environments.

4. High quality processing performance and convenient processing;

5. Enough to meet the preparation requirements of various colors, so that the shell of the charging gun has a diversified and personalized appearance.

6. The material has been certified by RoHS, UL yellow card and CQC.

2、 Communication Charging gun Material scheme of charging socket.

Scheme 1: polyester (PET) material scheme.

Material No.: polyester fr1300 (selon)

Note:

1. Check whether the material has passed ROHS and UL yellow card certification.

2. (iec60695-2-13) GWIT temperature: (0.35 mm) 900 ℃.

3. (iec60695-2-12) gwfi (0.35mm) 960 ℃.

4. (CTI / UL grade 3) CTI: 250vcti ≥ 175v.

5. Long term service temperature RTI value: 155 ℃.

6. Flame retardant ul94-v0-0.8mm (1.6mm 5mm)

7. Good dimensional stability and excellent processability.

8. High intensity, can meet the color matching requirements of various colors.

Scheme 2: PA66 material scheme.

PA66 material No.: pa66fr2400 (selon)

Note:

1. First check whether the material has passed ROHS and UL certification.

2. (iec60695-2-13) GWIT temperature: (3.0mm) 850 ℃.

3. (iec60695-2-12) gwfi (0.4mm) 960 ℃.

4. CTI (leakage trace index) 600vcti.

5. Halogen free flame retardant ul94-v0-0.4mm.

6. High temperature resistance and high strength;

7. Good thermal stability.

3、 Use communication Charging gun Precautions for

1. Pay attention to charging power: current and voltage information.

2. Pay attention to the communication protocol: 4-wire system or 5-wire system

3. Pay attention to the protection grade: whether the angle between the charging pile cable and the pile and the hanging gun comply with the drainage principle.

4. Note the overall dimensions:Charging gun The outline dimensions of the shall fully comply with the latest national standard dimensions (most enterprises have the problem of interchangeable dimensions)。

5. Pay attention to the homing structure of the charging gun.

6. If no one is watching, the homing detection of the charging gun shall also be considered. The locking device of the charging gun shall not be touched at will.

7. Pay attention to the service life of the cable.

8. Pay attention to whether the charging gun material can be used outdoors

9. Pay attention to the outer diameter of the charging cable.

To sum up, communication Charging gun The material is required to be used outdoors, so the material should have the following characteristics: weather resistance, high and low temperature resistance, oxidation resistance, UV linear resistance, weather resistance, fire resistance, gasoline contact resistance and power safety.
