Fixation clips offer you a reliable solution for fixation and guidance of cables in vehicles and on profiles. WKK provides high-quality fixation clips developed by our subsidiary WKK Automotive. We supply edge clips (also for corrugated tubing), clips with fir tree or with arrowhead and solar clips. The products are available, with and without cable ties, for various profile thicknesses and hole diameters.

Own production and quality

Our subsidiary WKK Automotive has its own production facility for the development and production of high-quality fixation clips. The clips are made of plastic (polyamide 6.6: heat, weather and impact resistant). You can expect the products to have good impact resistance, heat resistance and tensile strength (if cable ties are supplied). If desired, you can also have custom made clips, developed by us, that meet your specific requirements.

WKK supplies the following fixation clips:

• Edge clips
• Edge clips for corrugated tubing
• Clips with fir tree or with arrowhead
• Solar clips
  
  

Edge clips with cable ties and/or corrugated tubing

An edge clip is a small plastic fixation clip with a metal clamp, which you can mount on a plastic or metal profile. The product is often used in the automotive industry. Nevertheless, you can use the product wherever you have to deal with cables or corrugated tubing that you want to attach and guide along profiles in an easy way.

The main advantages of edge clips are ease of use (no drilling, welding or gluing needed) and the robustness of the product.

WKK also supplies, if required, the complementary cable ties and corrugated tubing.

Clips with fir tree or with arrowhead

In addition to edge clips, we also have a wide range of clips with fir tree or with arrowhead. These fixation clips are specially designed for mounting of the clip in a drill hole.

Solar clips

Are you looking for mounting clips for applications in the solar industry? WKK has various high-quality solar clips. These fixation clips are often used with cable ties, corrugated tubing and/or cables.
 

Many sizes available from stock

Our mounting clips are available for various profile thicknesses and hole diameters. The size range is determined, so you will almost certainly find a clip that is suitable for your intended application.

Crimp terminals ensure a safe electrical connection between a cable and a connection piece. They are also used to connect two power cables. Crimp terminals are popular in electrical engineering, automotive and industrial environments, among others. WKK supplies various types, sizes and colors of crimp terminals. We also sell various crimp terminal accessories, such as crimp terminal assortments and crimp tools.

When to use a crimp terminal?

You use crimp terminals when you want to safely connect or disconnect cables to electrical appliances, power or control panels, junction boxes or machines. In addition, they are also used to merge power cables. The product protects devices, cables and people. In most cases, crimp terminals are used for temporary connections, which are easy to disconnect or replace. Permanent installations are also possible but less common.

How does a crimp terminal work?

Crimp terminals offer one of the safest and most commonly used methods for ‘closing’ cables. The product is developed to make cable termination and removal for maintenance or repair very easy.

The electrical cable transfers electrical power to, for example, an electrical device or control panel. The crimp terminal ensures a secure connection. It is important that the cable size and electrical capacity of the connector are correct. If the connection or current capacity is incorrect, a short circuit or a leak may occur. This may result in damage to a machine, device or even endanger the technician.

Crimp terminals and bootlace ferrules are not the same. In principle, both product groups have the same global goals (protection and guidance). However, the applications are different. A crimp terminal connects cables to other cables or devices in order to safely extend the electrical connection between various ends. A bootlace ferrule, on the other hand, is used for cables that reach a final destination (screw terminals, such as a terminal block or automatic circuit breaker). In addition, the connector of a bootlace ferrule is crimped, in case of a crimp terminal it is the insulation sleeve.

Different types: uninsulated and insulated crimp terminals

WKK supplies different types of crimp terminals: uninsulated and insulated. In a limited environment or in a system where cables are close together, you should use insulated crimp terminals. Otherwise there is a risk of a short circuit between the cables.

Uninsulated crimp terminals are used for locations where there is a lot of space or when a large ‘area’ needs to be supplied with electricity or an electrical signal. Uninsulated crimp terminals are a cheaper solution than insulated variants. You can also insulate uninsulated crimp terminals afterwards (watertight) with heat shrink tubing.

Material of the connector

A crimp terminal has a connector with an optional (full) insulation piece. WKK supplies connectors in copper and brass. The insulation material consists of PVC, nylon or polyolefin.

The connector material selection depends on your specific application. Copper, for example, is a better electrical conductor than brass. Brass, on the other hand, is more resistant to corrosion than copper.

Insulation options

PVC insulated crimp terminals are the most common and protect against short circuits. The PVC and the copper connector are shrunk to make the connection to a wire.

The nylon insulated option is shrunk on the wire and on the wire insulation. This results in an improved pull-out strength of the crimp terminal. This variant is ideal for heavy industrial applications, because the shrinkage ensures extra protection.

The polyolefin insulated variant uses plastic and adhesive which insulates the connection. After shrinking or soldering the connection, a heat gun is used to shrink the insulation around the wire. The adhesive provides a water-tight and moisture-tight seal. This method is ideal for applications where dust and moisture can endanger the connection.

Colors and sizes

The WKK assortment consists of three colors that correspond to a certain size. You will also find the colors on the crimp tools. WKK supplies crimp tools in the colors:

• Red: wire range 0.5 ~ 1.5 mm2, AWG 22 ~ 16
• Blue: wire range 1.5 ~ 2.5 mm2, AWG 16 ~ 14
• Yellow: wire range 4.0 ~ 6.0 mm2, AWG 12 ~ 10
  
  

Useful crimp terminal accessories

In addition to the main product, WKK also supplies various useful accessories. You can think of crimp tools for crimp terminals and crimp terminal assortments. We also sell quick splice connectors and fuseholders.

Highlighted types and applications

Frequently sold crimp terminal types are ring, spade and pin terminals. Below you will find the most commonly used application per type:

Ring terminals and spade terminals are often used with a screw (e.g. on a battery). Ring terminals are often used in the automotive industry and are ideal for connecting a mechanical relay or for connecting contactors to engines or other car circuits. A spade terminal is ideal for applications where the ring does not fit around the screw due to an obstacle. A pin terminal is used for applications with a plug connection.

Available in almost all types, sizes and colors. WKK is official distributor of ABB/Thomas & Betts and supplies also cable ties of the brands Ty-Rap®, Ty-Fast® and Ty-Met™.
