Spiral connecting cables

Spiral connecting cables are used for the electrical connection between towing vehicles and trailers in the commercial vehicle sector.

Non-insulated crimp connector

Non-insulated crimp connectors are typically used in splash water-protected areas of a vehicle and serve primarily as detachable system elements for electrical and mechanical connections/branches of cables. In the course of time, a number of different contact systems have become established, depending on the application area and vehicle age.

Insulated crimp connectors with shrink-on insulation (Duraseal)

The insulated "Duraseal" crimp connectors have a shrinkable nylon cap with adhesive that can be used to make a waterproof connection between cable and contact. To this end, the nylon cap is heated using a hot-air gun (or other heat source) to approx. 135°C . At this temperature, the cap material firmly encompasses the cable. Other insulation solutions (e.g. heat-shrink tubing/sleeves or insulating tape) are therefore not required.

Insulated crimp connector

Insulated crimp connectors are crimped using an appropriate tool at the coloured end in order to create a safe, rigid contact to the cable. The insulation material is made up either of PVC (max. temperature resistance of 80°C) or of nylon (max. 105°C). The insulating sleeve has a special "easy-entry" funnel shape to ensure better guidance of the cable.

Cable end sleeves

Cable end sleeves avoid the need to fan out single strands of multi-wired copper cables and facilitate the process of guiding them into terminals. For this purpose, the end sleeve is pressed onto the stripped part of the cable. Depending on the tool used, the pressed-on sleeve can have many different shapes. The range corresponds to DIN 46228-4 in terms of design and dimensions.

The material is made of copper with a nickel-plated surface and a plastic sleeve in PVC.

CWT soldering sleeves Soldering connectors in accordance with DIN 46211

In addition to the crimp connections, the solder connectors present an additional option for connecting cables. To this end, the stripped cable end is guided into the connector and then treated with preheated solder fluid. After the soldering material has cooled down, a secure, firmly-bonded connection is established.

Cable connector boxes

If different, multi-core cables are to be linked together, it can be difficult to maintain the overview. For such cases, the HELLA cable connector boxes offer a safe and easy-to-use bundling solution that keeps everything neat and tidy and clear. The lockable, fire-resistant box provides the necessary protection for the individual wires.

"SUPERSEAL" plug connections

"SUPERSEAL" plug connections comply with IEC 529 regulations and also with DIN ISO 40050, and come with protection class IP 67, which offers the maximum level of water and dust proofing. The quality of the "SUPERSEALS" makes them ideal wherever other connecting systems reach their limits because of adverse pressure or humidity conditions.

DEUTSCH "DT series" plug connections

The concept of the DEUTSCH "DT series" plug connections combines high-quality materials with a connecting system characterized by both reliability and easy handling. Thanks to these qualities, the range is particularly suited to applications where maximum output is required but with a low failure rate despite tough environmental conditions.

Cable straps with edge clips

Properly fastening a cable bundle often requires more than the cable tie itself. Our cable ties are weatherproof, flame-resistant and also resistant to diluted organic acids, oils, petrol, salt water, solvents and all kinds of grease. They even offer perfect support for extremely small bundled diameters such that no cable lining or other attachment aids are required.

Cable ties

Cable ties make it possible to quickly fasten and bundle cables, wiring harnesses and a large number of other component parts. The system, which has been around for decades and undergone little change, is just as simple as it is affordable and universal.

Drills, chassis cable clamps, corrugated tubes, spiral tapes

Bundling and fastening cables.

Insulating tapes

Electrically insulating adhesive tape is made of non-conductive material and is suitable for a wide range of applications in the field of vehicle repairs without negatively impacting the vehicle electrical system. Whether it’s a case of bundling, fastening, temporary insulating or colour coding ─ the tried-and-tested all-purpose system always provides reliable results. In the meantime numerous special variants are available that have shown themselves to be particularly suitable for a specific area of application.

Battery terminals

Whether as a spare part or as an original equipment component – HELLA universal clamps provide the best service with their high level of hardness of material and their corrosion resistance. The range is strictly oriented towards the common standards in place for battery terminals.

Ground straps

The highly flexible electrical conductors have been used in a range of electrical vehicle applications for decades. As the name implies, it is all about applications such as discharging/grounding of EMC interference or static charges. In this context, the ground strap must reliably withstand high currents such as those that can occur between the starter and battery. If the electrical system is malfunctioning, a defective or non-existent ground strap can often be the cause.

Hose/pipe clamps

Hose and pipe clamps are typical fastening elements for liquid line mechanisms. Our universal hose clamps are particularly well suited for applications that involve high mechanical loads because of their high tensile strength, high breaking torque and uniform force distribution. All measurements/configurations are available in a selection of alloy variants.

Spring band clamps

Unlike standard hose clamps, spring band clamps (SBCs) have a flexible holding mechanism. This greatly increases their lifetime if there are frequent temperature fluctuations in the application area (e.g. for air or fuel circuits). When the fluid system expands in diameter as a result of elevated temperatures, the SBCs adapt accordingly as they also do for a temperature-induced reduction in cross-section diameter. This, in turn, ensures optimal fixation.

Connector base/plug-in base for bulbs

Plug-in bases for bulbs are used in special applications such as auxiliary headlamps in agricultural and construction machinery.

They are also used to carry out fair-value repair work on headlamps whose base has fused with the bulb or where corrosion has formed and led to contact resistance.

Trailer connection units / voltage transformers

Trailer connection units allow the use of 12 V trailers on vehicles with 24 V operating voltage. The integrated voltage transformer permits operation without a separate charge compensation device. The trailer connection unit has 7 channels for the light function of the trailer. Malfunction of a 12 V trailer’s direction indicator is indicated by the C2 series control lamp.

Product range case

HELLA product ranges include a selection of the most common products in a particular topic area – well laid out and compact in a high-quality, fully mobile concept. Four cases can be integrated in the practical Handy Box that offers not only a handle for easy transporting, but also many options for safe securing of the item.

Basic crimping and releasing tool

The "Basic" crimping tool set allows many different kinds of crimp connections to be created safely. The inserts can be changed quickly and easily and thus offer a time, space and cost-saving alternative to the need for several individual tools. The matching release tool set is the appropriate counterpart for the removal of existing connections.

Professional crimping and release tool

Thanks to its special profile geometries, the "Professional" crimping tool enables very precise radial contacts to be set up. The fixing concept of the patented crimping tool set ensures that the tool inserts are perfectly positioned. Furthermore, the pliers have an extra cutting and stripping unit in the handle which makes the tool set especially versatile. The whole set is rounded off by a modular set of unlocking blades.

"Heavy Duty" tool system

The linear crimping technology of the HELLA "Heavy Duty" tool system offers the highest level of precision finishing. Unlike conventional radial pliers, this concept proves its worth because of the uniform distribution of force during the crimping process. This feature allows it to produce consistently high-quality work results. The system’s modular design allows you to put together your own individual combinations and also to separately exchange basic handles and crimping or release tools.
