Screw connection with tension sleeve

The screw connection is maintenance-free and, with the multi-conductor connection, enables a high level of flexibility and a high load-carrying capacity. Connections with a wire guard are particularly well-suited for semi-industrial applications in building automation, safety technology, and telecommunications. With connections via tension sleeve, you can ideally connect industrial applications with high demands on contact reliability. The front screw connection is suitable for narrow device fronts and PCB racks.

Example figure of a lever Push-in connection

In the field of spring connections, Phoenix Contact offers you connection technologies with Push-in spring connection, lever Push-in connection, spring-cage connection, SUNXCLIX spring connection, and the T-LOX knee-lever connection. The easy operation of this connection method saves device manufacturers time during installation. The connections are also vibration-free due to the spring contact elements.

Example figure of an IDC displacement connection

The IDC insulation displacement connection is a particularly time-saving connection technology that does not require conductor pretreatment. With this connection method, the cutting metal cuts through the insulation and establishes a reliable connection to the conductor.

Mounting types

PCB terminal blocks can be mounted on the PCB through a variety of methods. These methods include wave soldering, THR soldering (Through Hole Reflow), and SMT soldering (Surface Mount Technology). This means that you can assemble PCBs efficiently and process them reliably.

Example illustration of a wave soldering process

Wave soldering is the classic soldering process for manufacturing electronic modules that are predominantly assembled with through-hole components. The soldering contact inserted through the PCB and the soldering on the bottom of the PCB are characteristic of this soldering process.

Example illustration of surface mount technology

Surface mount technology (SMT) is used for surface mounting components. The components are assembled on the PCB surface in solder paste and soldered using the reflow soldering process. This method requires special components with corresponding surface contacts.

Example illustration of through-hole reflow soldering

Through-hole reflow soldering (THR) enables the integration of through-hole components made from high-temperature material into the SMT reflow process. During this process, the through-hole contacts are inserted into the holes filled with soldering paste and soldered using the reflow soldering process.
