What was the connection terminal and single wire connector?
Connection terminals and single wire connectors are conductive elements that connect electrical cables of all kinds with each other and thereby secure a protection against accidental contact. The connections can be permanent or removable. These components consist of an electrically conductive component, which is equipped with mechanical parts in such a way that cables can be connected with each other by screws, clamps or crimping and are protected against accidental release. This means that such connections are also safe for permanent mechanical stress, such as vibrations in vehicles or household appliances. Many terminals and connectors are equipped with strain reliefs, which keep the mechanical tensile stress away from the actual electrical contacts.
There is an insulating sleeve around the actual electrical connection. This may also be a case that meets the requirements of electromagnetic compatibility (EMC) to the shielding and grounding.
Connection terminals and single wire connectors are used wherever cables are branched, extended or shortened or when repairing defective cable sections.
The design and electrical equipment in this category is based on the voltage and current ranges in which these installation elements are used. Many of these connectors are designed so that a connector is suitable for a range of wire cross-sections. Transparent housings allow visual inspection of the connection. Some elements have test openings for measuring devices.
The insulating housings are designed in such a way that they do not impair the insulation of adjacent cables even in confined spaces in branch or socket outlets.
Depending on the number of poles, cables can be clamped together with connection terminals/single wire connectors, either as a connection or as a branch.
The classic is here the so-called luster terminal, which is used for connecting usually more ornate chandeliers decorated with glass prisms or similar. The insulation material of this clamp is made of porcelain and is available from Conrad.
Some connectors are labeled for specific cables in the electrical domestic electrical installation.
Which connection terminals and single wire connectors can you find at Conrad?
The connection terminals and single wire connectors from several manufacturers can be selected in the Conrad shop according to price, novelties & offers (with RoHS), customer evaluation, branch availability and the following criteria:
Cross section flexible or rigid (min./max.)
With these four separate selection options, the selection of the connection terminals and single wire connectors can be adapted very well to an existing electrical installation. Cross-sections from 0.008 to 35 square millimeters are available. In addition, a distinction is made here between rigid and flexible cables that can be connected to each other.
Nominal current
The bandwidth ranges from 2 to 57 amps.
Colour
There are 22 colors or color combinations to choose from.
Category
The "Category" limits the use. This refers to the installation location such as socket, light or branch terminals, the type of connection as quick-connect connectors (in insulation displacement technology), as connectors with integrated fuse holders or as distributor blocks. Some products are also listed here as assortments. Under this menu item you will find the classic design of the so-called luster terminals under "porcelain terminal".
Number of pins:
Describes the maximum number of individual wires to be connected, here from 1 to 12.
For connecting terminals and single wire connectors, larger quantities are also available than low-cost industrial packaging.
FAQ – Frequently asked questions about connection terminals and single wire connectors
What was to be observed when making and disconnecting the connections?
- In case of doubt, consult a specialist to ensure that the correct operation of an electrical system is not endangered.
- Do not loosen or connect these elements when they are energized.
- Secure the system being worked on against accidental re-activation by third parties.
- Before starting work, check that the voltage is free with a suitable electrical test tool. These are also available in the Conrad shop.
- Always connect metallic (conductive) housing parts to the protective conductor system.
- Carefully check the connected cables and connectors before switching them on again.
- Take special care in wet conditions.
- Use only recommended and intact tools. Please refer to the data sheets available for download at the product.
How long do connection clamps and single wire connectors last?
The service life is not explicitly specified. One exception is crimp connections as in insulation displacement technology, which are only suitable for one-time use.
How can ich detect defects on these terminals?
- Heating and associated deformation due to oxidation on the Contact skipped
- Hard-to-operate or no longer-to-operate interlocks due to contamination Or deformation
- Broken housing parts with poor contact protection
- No longer gripping strain reliefs
- Leakage through cracks, allowing media to enter the original sealed housing
What was to be observed when replacing connection terminals and single wire connectors?
Use the same terminals or further developed successor models from the same manufacturer if possible.
If such a replacement is not available, select a product with the same electrical, mechanical and, not to forget, thermal characteristics.
Check the integrity of the cable ends before leaving these cables in the system.
