Distribution and protection
Connecting cables.
Cable lugs, connectors and terminal blocks.
An on-board installation is only as good as its connections. Firmly crimped cable lugs and butt connectors for permanent connections, waterproof circular connectors for cables that need to be disconnected, and terminal blocks for order in the distribution box. Here you will find what fits where, with cross-sections and protection ratings from the philippi range.

Permanent connections: cable lugs and butt connectors
Connections on board must be mechanically secure, electrically durable and accessible. That means crimping with the right tool instead of soldering or loose clamping. Tinned strand ends in screw terminals loosen over time because the tin creeps under pressure.
- RKS tubular cable lugs: made from E-Cu tube, electro-tinned, in 29 versions from 6 to 120 mm² with hole diameters from 6 to 16 mm, for hexagonal crimping.
- QKS crimp cable lugs: ring terminals for 1.5 to 6 mm² with 4, 5 or 6 mm holes, for example for bus bars and terminals.
- SKS pin cable lugs: for terminals and plug connections, in three sizes from 10 to 95 mm².
- Butt connectors: The SV joins two identical cables from 16 to 50 mm² by crimping, without a soldered joint.
For crimping tubular cable lugs and uninsulated cable connectors, the WW 6/70 crimping tool covers 6 to 70 mm² using the hexagonal crimping method.
Rather not crimp yourself? In the cable configurator you choose cable, length and cable lugs. philippi crimps the lugs on and delivers the cables ready made up, matched to cross-section and fuse.
Sealing and marking
Moisture is the biggest enemy of a cable connection. Heat shrink tubing with an internal hot-melt adhesive seals the joint permanently. The WSR shrinks at a 3:1 ratio and also holds on irregular transitions. The SSK 19 in red and black seals tubular cable lugs and marks the polarity at the same time. The SSB set contains black heat shrink tubing in five diameters.
With the KMS 10 cable marking you mark cables permanently with digits from 0 to 9. That saves time with every later fault-finding.
Detachable and waterproof: circular connectors
Where a cable must be disconnectable, for example at the mast, at navigation lights or at the shore power inlet, waterproof circular connectors are used. The philippi 692 series has a glass-fibre reinforced plastic housing, screw terminals and a threaded locking ring that stays closed even under vibration.
| Connector | Poles | Per contact | Protection | Typical use |
|---|---|---|---|---|
| Series 692 | 2 or 4 | 16 A, up to 2.5 mm² | IP67 | Navigation lights |
| Series 692 | 7 | – | IP67 | Wind instruments |
| Series 692 | 2+PE | 16 A, up to 2.5 mm² | IP67 | Shore power 230 V |
| Series 694 | 4+PE | 20 A, up to 2.5 mm² | IP65 | Shore power 400 V |
| Subminiature 720 | 3 or 5 | – | IP67 | Data cables |
The values are taken from the product information in the shop. Coupling plug and coupling socket connect two cables to each other, flange plug and flange socket are mounted firmly on a wall or housing. Angled housings, surface-mount housings and protective caps complete the 692 series for deck mounting and for unused connections.
Flat plug connections
For switches, loads and devices with flat plug terminals there are flat receptacles with a 6.3 mm tab width. They are crimped and remain detachable, which is practical for maintenance and extensions. The insulated FSI are colour-coded by cable cross-section, so you reach for the right size straight away during installation.
Order in the distribution box: terminal blocks
DIN rail terminal blocks are the central connection point for load and control cables in the fuse and distribution box. Every cable is quickly accessible for service and later additions. philippi offers the RKL 10/20, RKL 16/4 and RKL 30 for on-board networks of different sizes and the RKL 14 for two-pole fused systems.

Frequently asked questions. Answered briefly.
Crimp or solder cables?
On board and in vehicles, connections are crimped. A crimped connection made with the right tool is firm, gas-tight and vibration-proof, without the risk of cold solder joints. Tinned or soldered strand ends in screw terminals, on the other hand, loosen over time because the tin yields under pressure.
Which cable lug fits my cable?
Two dimensions decide: the conductor cross-section and the hole diameter matching the stud. RKS tubular cable lugs are available from 6 to 120 mm² with holes from 6 to 16 mm, QKS crimp cable lugs from 1.5 to 6 mm² with 4, 5 or 6 mm holes. A hole that is too large reduces the contact area.
What protection rating does a connector on deck need?
For permanent use on deck and outdoors, a sealed circular connector is required. The philippi 692 series is protected to IP67, the 694 series to IP65. Close unused connections with the matching protective caps so that moisture and salt cannot reach the contacts.
Coupling or flange: what is the difference?
Coupling plug and coupling socket connect two cables to each other, for example in a cable run to the mast. Flange plug and flange socket are mounted firmly on a wall, a housing or in the deck. For deck mounting, the 692 series offers matching angled housings and surface-mount housings.
What do I need terminal blocks for?
DIN rail terminal blocks bundle load and control cables at a central, labelled point in the distribution box. Instead of searching laboriously for cables, you can reach each one individually during service. Combined with permanent cable marking, the installation remains easy to trace even after many years.
