Krone: Disconnection, Block, Connector, and Module

Regardless of the type of module used, the Krone contacts always operate on the same basic premise. Plastic-insulated copper or jumper wires are forced into the contact slot between the contact jaws using the insertion tool S, which is angled 45 degrees away from the wire’s axis.
While twisting and cutting through the insulation, the contact jaws nick the conductor at obliquely opposing sites, the jaws expand axially. Twisting the contacts and applying constant torsion and return force stresses to the contact jaws creates two gas-tight contact surfaces.
Melontel, a TUV certified factory established in 1995, can provide you with a full range of Krone products. At the same time, Melontel also has excellent research and development capabilities. It develops more than 20 new products every year, and provides lifetime after-sales service to provide a strong product guarantee for your FTTH construction.
Molded in plastic clamping ribs protect module contact sites from stress and tensile pressures, as well. In order to keep the insulation and conductors in place, these plastic clamping ribs are used.
When a successful connection is made, the Krone insertion tool emits an audible “click.” Wire is trimmed to the correct length after connection is made using the insertion tool in the same process.

Main Distribution Frame and perfect connectivity products frequently make use of the Krone 10 Pairs Disconnection Module. The IDC (Insulation Displacement Connection) mechanism is used by Krone LSA-PLUS. Flame retardant performance PBT / ABS is used for the Krone LSA’s exterior. The contact pin on the Krone Module is made of phosphor bronze and silver-plated. Connect to something that is sturdy and reliable.

As a result, this module is most frequently used in audio, DC, control, and communication applications. Depending on whether the screen is floating or terminating, this is a good place to terminate unscreened pair connections as well as screen-screened audio cables.

Therefore, it is much faster and easier to maintain than solder tag systems because of the Krone LSA-Plus connection system’s reliability and cost-effectiveness, making it an excellent choice for communications, broadcast, and data wiring installations.

Certainly, standard 10 pair unscreened termination modules and a size-compatible 6 pair + screen module from Krone are the foundations for the company’s extensive connection and wiring system offerings. Accessories include testing, alternate equipment termination, cable distribution, and jumpering.

With Krone’s insulation displacement connection, wire stripping, soldering, or screwing is not necessary. To make connections, the Krone inserter tool is inserted into a module slot. Clamping rings and two 45-degree metal contact arms make up the slot’s design. When these cutters cut through the wire insulation and into the conductor, a spring force keeps the wires in touch. A gas-tight seal is formed between the conductor and contact. The inserter tool accomplishes the process with the correct force.

Also, it cuts the surplus wire off after termination with the same action. All contact resistance, aging, and durability standards, including British Telecom’s D2920 regulation, are met by Krone connections. Anybody can learn the Krone technique in just a few minutes, regardless of their background in engineering. Up to 90% of the installation time can be saved. Wiring adjustments can be accommodated quickly and easily by re-termination.

Krone modules have two rows of contacts: one for permanent connections, and the other for short-term connections. Modules can be connected and disconnected in a variety of ways. Test probes and other accessories can access the equipment through connection modules, which establish a permanent connection between the jumper sides and the equipment. It’s possible to listen and break circuits using a spring contact connection in the disconnection module.

In communications installations, disconnection modules have become standard. Some broadcasters, however, choose to use the connection type for high-quality lines, sacrificing a little flexibility in the process.

There are two wires of equal diameter in each Krone connecting slot. From 0.44 mm to 0.65 mm, the optimal conductor and insulation diameters are (26-22 AWG). Conductors with a diameter of 0.5mm and a single strand are the preferred choice (standard telephone cable size per CW1308 spec). Stranded wire, such as 7/0.15 or 7/0.2, is another option. When using smaller diameter conductors, the insertion of stranded wire may cause some strands to be severed. In a single contact slot, stranded and single-core wires should not be mixed.

All copper connectivity solutions are designed to ensure safe and secure transmission of voice and data through a wide range of mediums, including ISDN, ADSL, VDSL and cable television.

The Krone Disconnection Module, Connection Module, Highland Module, STG Module, Back Mount Frame, and Gas Discharge Tube Protective Unit are all on the market.

All LSA-PLUS back-mount frames are able to support this. Suitable for use on all xDSL and ADSL 2+ connections, dependable telecoms Based on LSA-PLUS connectivity, modular systems can be designed and installed. Flexibility of usage, long-term environmental stability and LSA-PLUS Series 2 accessories are all welcome. By using a single pair of protection (IPM), type Approved against TEC, MDF Specification GR/CTN-01/04 May 2005 and Life durability of 250 cycles.

Voice and data are commonly distributed via distributors at the entrances of buildings, in-floor distributors, and PABXs. Cross-connection cabinets and terminating boxes are two other options.

As ‘Audio over IP’ becomes more common, Krone is becoming less necessary. However, if you have an abundance of analog gear, connecting it all straight to the mixer can be a hassle. Reconfiguring your connections is a cinch when everything is hooked into the krone frame. Instead of spending hours soldering new cables, you simply move the jumpers.
Furthermore, Krone is a valuable tool in larger multi-studio environments as well. All of your studios are connected to a huge krone frame by multicore wires that begin in each of your mini krone frames. As a result, wiring signals from one part of the building to another is a breeze.
In a busy facility with several radio stations and continuously changing technical requirements, you would be regularly shifting jumpers around.
If you have more than one room filled with equipment, Krone may not seem like much of a benefit at first.
A “state of the art” facility would likely use a “audio over IP” technique, as well. There is no need for jumpering or patching since conventional networking hardware replaces the krone frames and enormous analog multicore cables.
Krone blocks are my current preferred means of landing cables, and they exceed everything else that is out there in terms of their advantages, which include:

• The connections from trunk cables to individual cables are established on an “inside” and an “outside” row on both the left and right sides of the block.
• Solid or stranded wire can be used.
• You can double-punch on either row.
• To bridge or break the circuit leading to the outside row, a “shoe” can be inserted in a specific spot.
• From DC to category 5, Krones can handle everything (and perhaps beyond).
• They’re cheap and widely available.
• Efficient in terms of the space they consume.

The Krone Group, a German telecommunications company based in Berlin, founded Krone in the 1970s. Tyco Electronics purchased Krone from Tyco Electronics in 2010 after ADC Telecommunications purchased it in 2004. ADC/Krone Telecom Solutions was bought by CommScope Inc. in 2015.
Krone LSA-PLUS (or just Krone) is a well-known moniker for a telecommunications insulation-displacement connector. The 110 blocks have a unique European incarnation. Audio interconnections and the control systems that accompany them are regulated by Krone wiring in broadcast systems when Krone wiring is employed in the Krone LSA-PLUS system. Multi-pair audio cables have been produced specifically for the system by organizations like the BBC.
To add, Krone connector as a variant is a type of connection system component presently available from TUK Ltd and Commscope (USA). The original Krone corporation no longer functions. Products from both firms are interchangeable and are effectively identical. The product type codes, such. 237A, British Telecom references who originally were the bulk users of this type of connection system and selected the blocks and accessories.
In comparison to 110, Krone has contact slots that are angled 45 degrees from the wire. When using stranded conductors, Krone connectors are preferable to IDC punch blocks in the 66 and 110 styles. Wire insertion into the connections requires a Krone-specific punch down tool, which is made of silver to prevent corrosion. There are Krone blocks that can withstand frequencies far higher than ordinary blocks.

The 8- and 10-pair Krone disconnecting modules are available for use in telecommunications and data communication networks. Modules for disconnection feature two-piece contacts that are normally closed, and they can be disconnected.
Individual pair disconnection and four-wire test access are also included in this package. It is possible to monitor access and overvoltage with connection modules because they have a single-piece contact that links permanent wiring and jumper wiring.
Moreover, cross-connect modules for high-speed data and voice. Available in 8 and 10-pair disconnect models. High-speed LAN and WAN systems benefit significantly from these modules’ extra transmission capacity. We utilize the silver-plated LSA Plus contact concept. Over 60 countries have adopted this technology as the industry standard. The gas-tight connections offer a solid and long-lasting connection. These modules can be patched, jumpered, or utilized in a patch by exception configuration.
Hence, high-performance cross-connection technology allows users to jump and patch on the same module. Installing and maintaining this system is a breeze. Two four-pair UTP wires are terminated. When adding, moving, or changing components, the system is recommended to be hardwired, and patch cables (which override the installed connections) be used. Individual date circuits can be tested through the center port using modules, which reduces network downtime. These 10-pair LSA-PLUS Series 2 modules have identical dimensions to utilize standard mounting hardware. Dedicated frames are also available -see the frames, racks, and cabinets section.
LSA-Plus disconnection module can be used to detach the LSA-Plus disconnection module from the LSA-Plus disconnection module. In order to construct various measuring and testing circuits, patch and test cables can be used. The disconnection module technique has a substantial impact on high-quality protection systems.
Thus, compared to the connection modules, the LSA-PLUS separation modules have extra functionality because the circuit can be severed via plugs or cables when required. Incorporating “intelligent” protection, measuring and testing in two ways, connecting via cables, or “looping in” functional aspects are just a few of the many possibilities made possible by this feature.
