Identifying requirements

A new junction box design that is waterproof (IP64) and provides strain relief without potting.

  • Option to change cables is needed
  • Cables are often damaged by sharp edges of metal roofs or rat bites
  • Cables cannot be replaced due to the potting of the junction box
  • Without potting: no waterproof & poor cable tension
Customer Oriented Engineering

To solve the problems we started a design process with our customer.

  • Strain relief protects the cable
  • Strain relief gives the opportunity to replace cables
  • The lid of the box can be opened and closed for repairs without affecting the tightness
  • Specially designed and enlarged rear side avoids errors in the silicone bonding of the box to the module
jbox
  • (A) Waterproof sliding lid without silica glue potting. This can only be opened by trained technicians
  • (B) Strain relief to increase cable pulling force and also with the ability to change the cable
  • (C) Notch, which effectively prevents the glue from overflowing
