PV-HBE4x laser-weld series · PV-HBE4x laser-weld module junction-box series
Zhejiang CHINT Xinhui Photovoltaic ↗A three-box module junction box built around a laser zone and a reserved solder zone on each copper terminal. The instruction gives 25A and 30A subtypes; ask CHINT Xinhui for a controlled specification before quoting the 35A shown on the webpage.
Covers the PV-HBE4x laser-weld branch. The marine, 2000V, modular and quarter-cell boxes share the label and have entries of their own. The fifteen-page instruction spans a narrower electrical and material range than the webpage.
General illustration of module assembly equipment, not a photograph of this model. Ask the manufacturer for current photographs and layout drawings of the configuration offered.
START WITH YOUR PRODUCTION TASK
Ask CHINT Xinhui which document revision governs, choose the x subtype and diode, then trial ribbon joining, attachment and filling on your own module with current certificate annexes in hand.

What the box design changes at your assembly station
A barrier that shields the sealing wall
A plastic barrier stands 2.4mm above the copper terminal so weld slag and heat stay off the inner wall. After your joining trials, inspect the wall and the seal on real samples.
Laser zone plus solder zone
The terminal carries one zone for laser joining and a second zone held back for solder. CHINT Xinhui describes using solder when a laser joint is abnormal or when a replacement leaves a short ribbon. Agree the rework rules and limits with the factory before you plan module repairs.
Cable welding kept apart
The cable is resistance welded in a bent region set away from the laser area. Ultrasonic locking fixes the cable exit to the body and base. Each of these steps needs its own settings.
Room for air and adhesive
An inclined outlet cavity gives trapped air a path out over the filling plane, and the terminal support is hollow so adhesive can reach the base and module cavity. Set a fill inspection and cure conditions so voids show up in your trials.

Sizes and materials listed in the instruction
| Interface | Listed entry | What to request |
|---|---|---|
| Outside boxes | 72×25.78×17.1mm each | Controlled drawing with tolerances and cable clearance. |
| Centre box | 75.8×25.78×17.1mm | Its own drawing, since it is longer than the outer two. |

Attachment adhesive and internal filling are two steps
Bond at the shaded areas
A special attachment adhesive goes on the shaded areas, about 11.5mL in total. Ask CHINT Xinhui for the material, the dose tolerance and the surface preparation for your module.
Thread and join the ribbons
Pass each ribbon through its opening and onto the six copper positions in the drawing. Keep them clean and free of adhesive. Get the validated laser or solder procedure and the joint acceptance criteria from the factory.
Fill up to the marked plane
Internal potting must stay below the arrowed plane, which is a separate limit from the attachment dose. Request the potting material, total internal dose, air-release check and full cure schedule.
Snap the lid in the right direction
Seat the unmarked side in the latch first, then press the arrow side until it clicks, with the protrusions lined up. Check full engagement using an agreed inspection method.
Approve the finished module
Before repeat orders, run the electrical, sealing and module tests you need with real component lots and process settings. Ask for certificate annexes that match the standards the manual lists.

Handling rules for your work instruction
Keep connectors free of silicone
The manual forbids silicone or potting material touching the connector body. Keep the mating faces clean during box filling.
Protect the ribbon joint
Ribbons must be clean and free of adhesive, and the attachment adhesive must be spread evenly. Write both checks into your station instruction.
Never mate a set's own positive and negative
The manual warns against joining the positive and negative connectors of one set during installation. Mark polarity and module wiring clearly.
Watch chemicals and cable strain
Alkane solvents, strong acids or alkalis and pulling or hanging loads on the cables are excluded. Ask the factory to approve any new cleaner or fixture first.
Leave live work to qualified staff
Plugging or unplugging under load is forbidden, and outdoor maintenance is for professionals. The IP68 rating covers sealing; electrical isolation rules still apply.

Questions to settle before the quote
Can I order 35A from this instruction?
The instruction has 25A and 30A subtypes. For the 35A on the webpage, ask for a current 35A drawing, BOM and certificate annex.
Does the 50A reverse-current figure mean a higher working current?
No. It is a reverse-current parameter. The rated subtypes are 25A and 30A.
Is the 11.5mL dose the full potting amount?
No. It covers the shaded bonding areas. Internal filling has its own plane limit, so ask for the total dose and cure instructions.
Is the 2000V box the same product?
No. It sits in another catalogue branch under the same family label. The laser-weld subtypes run at 1000 V or 1500 V.
Will the solder zone always allow a repair?
CHINT Xinhui designed it as a rework option. Agree when repair is allowed, how often, and how it is accepted within your qualified assembly procedure.
