The KRONE “LSA-PLUS®” stands for a technically and economically superior quick connection system for all modern communication networks.
- L (Lötfrei): no solder
- S (Schraubfrei): no use of screw
- A (Abisolierfrei): no wire stripping
- P (Preiswert): cost-effective
- L (Leicht zu handhaben): easy to use
- U (Universell anwendbar): universal application
- S (Sicher und schnell): secure and fast connection system
Somewhat more comprehensive meaning is the “IDC”:
- I: Insulation
- D: Displacement
- T: Technology
The LSA-PLUS® System, with the LSA-PLUS® contact as its smallest functional element, is used for connecting, disconnecting, switching and earthing connections in telecommunications and data applications.
The patented LSA-PLUS® contact ensures the highest degree of contact safety under the most severe conditions even after years of use. A durable, gas tight connection is formed between contact and wire – resistant to corrosion and mechanical stress. These connections are made with a single action, with an audible indication, using the LSA-PLUS® insertion tool. The KRONE LSA-PLUS® contacts always function according to the same basic principle irrespective of the type of module used.
Using the LSA-PLUS® insertion tool S, the plastic insulated copper or jumper wires (4) are pressed into the contact slot (2) between the contact jaws (3), these being arranged at a 45° angle to the axis of the wire.
The contact jaws open in axial direction while at the same time twisting, cutting through the insulation of the wires and notching the conductor at obliquely opposite points. The twisting of the contacts together with constant torsion (5) and return force pressures (6) of the contact jaws create two gas tight contact surfaces.
The plastic clamping ribs (1) which are molded into the guide slot of the modules provide additional protection of the contact points against shock and tensile forces.
The insulation and conductor are firmly gripped by these plastic clamping ribs preventing any movement of the connection in the contact area.
A correct connection is signaled by an audible “click” of the LSA-PLUS® insertion tool.
In the course of the same action, the LSA-PLUS insertion tool trims the wire to the correct length after connection.
MODULE TYPES
1. Connection module (housing colour: grey)
The wires are connected to the opposite contacts at the system cable and at the jumper sides. Separate access contacts are located at the center of each pair; e.g. for monitoring, measuring and testing work, for switching using switching adapters or for connecting overvoltage protection magazines (3-point protection with overvoltage arresters or semiconductor components).
2. Disconnection module (housing colour: white)
Compared to the connection modules, the LSA-PLUS® disconnection modules feature additional functions, because the circuit can be disconnected using plugs or cords when required.
This feature provides a wide range of possibilities, for example the implementation of an “intelligent” protection systems, measuring and testing in two directions, connecting via cords or “looping in” of functional elements (e.g. attenuation plugs).
3. Switching module (housing colour: brown)
The individual contacts and hence the circuits of the LSA-PLUS switching module are disconnected when idle. By inserting plugs or cords, the circuits can be connected when necessary. It is also possible to install 5-point or graded protection.
4. Earth module (housing colour: red)
Depending on the version, the LSA-PLUS® earth modules (connection contacts) permit the routing of up to 36 cable wires to one common electrical potential. Via a permanently connected, flexible earth line, the back mount frame or an earth terminal is connected to earth potential.
5. Overvoltage Protection
The trend towards increasing investments in technical equipment for data processing and other communication systems at the workplace can result in substantial losses when this equipment is destroyed as a result of overvoltage (e.g.atmospheric discharges, lightning).
Apart from the material loss, the network downtime may cost many times the amount of the direct damage. In addition plant and network operators also face the danger to life and health. Too late – if no precautions have been taken.
Properly dimensioned overvoltage protection ensures the reliable lifetime usage of installations.
