General overview of the multipole connector product range
for railway applications
Tests
In 2006, we carried out laboratory tests approved by the French Railways SNCF, according to the above mentioned French standardsNF F 16-101
andNF F 16-102, the material we use in our connectors, which has been found to belong to class F1(Index FuméeI.F.(cid:148)20) as well as a toxicity
index (Index Toxicité Fumée)I.T.C. = 20.
Both these values meet the requirements set out by the French standards and by the Italian standard UNI CEI 11170-3 schedule 2, which relates to
electrical connectors.
We have also commissioned a qualified North American laboratory to carry out tests compliant with American standards, which have confirmed complian-
ce with the requirements set out by the US Federal Transit Administration “Recommended Fire Safety Practices for Rail Transit Material Selection” for
methods ASTM E 662 (NFPA258) (fume specific optical density), ASTM E 162 (ASTM D3635) (surface inflammability(cid:2)flame propagation index) and
Bombardier Transportation SMP800-C (fumes and gases toxicity).
Test reports are available on request (please contact our Sales Offices).
All requirements have been met.
Our connectors work under AC as well as DC current.
HOODS
IP68
The hoods with IP68 protection rating are particularly suitable for applications in the railway industry and
any application requiring high resistance to pressure, impact and corrosion.
They also ensure a good screening for electromagnetic compatibility, resistance to vibrations in complian-
ce with EN 61373 standard and to pressurised water.
STANDARD
Alarge number of enclosure versions are available with different combinations of component materials,
each one suitable to a specific installation: normal environmental conditions, high temperature environ-
ments, aggressive environments and environments that require electromagnetic compatibility. The coupling
stability and protection against accidental opening are assured by single or double closing devices compri-
sing levers, springs and pegs in stainless steel or entirely in plastic (CK and MK series). Sealing is assured
by special gaskets that protect the contact groups inside the enclosures against dust and aggressive
agents. In general, the coupled enclosures with the appropriate connections guarantee an IP66 (CEI EN
60529) degree of protection. Furthermore, the majority ofenclosures successfully complete the high pres-
sure hot water jet test required by standard DIN 40050 - 9 with IP69Kclassification.
Enclosures for applications with aggressive external agents (e.g. salt atmospheres or ambient pollutant) are
available - green or black (upon request) coated.
ACCESSORIES FOR MULTIPOLE CONNECTORS
The CR..FS Series anchorages are designed for use with connector inserts (normal or MIXO
modular) without enclosures and enable securing cables with clamps to prevent transmitting fric-
tion forces to contacts.
CR..SS anchorages (with grip to facilitate detachment) are used for earth connecting several con-
ductors and/or of the screen of shielded cables.INSERTS
MIXO 100A and MIXO 200A
Advantages of the crimping solution compared with traditional screw contacts:
- Greater resistance to mechanical stresssuch as vibrations and cable traction;
- Greater resistance to corrosion (gastight);
- Greater speed of connectionandconstancy of execution(independent of operator intervention);
- Improved electrical efficiencyof the connection (less current drop).
The contacts may be disassembled with a simple screwdriver,without the need for specific tools.
The crimping process is carried out rapidly and successfully due to the specific oil-pressure tool,
pre-fitted with the necessary positioner and with the die (upon request).

Spring terminal connections CKS,CSE,CSS,CSH
This type of connection offers the following advantages:
- no special wire preparation (other than stripping);
- no cable tool is necessary (series CSH). Ascrewdriver is the only tool required to remove the wire from the contact;
- it offers an excellent fastening solution and a great resistance to strong vibrations;
- allows rigid and flexible wires with cross-sections between 0.14 and 2.5 mm2(26 - 14 AWG) to be used.

軌道交通應(yīng)用連接器是專為軌道交通系統(tǒng)設(shè)計的一種特殊類型的電氣連接設(shè)備。它主要用于列車、地鐵車輛以及其他軌道交通設(shè)施之間的信號傳輸、電力供應(yīng)、通信網(wǎng)絡(luò)以及各類機(jī)械設(shè)備的接口連接。這些連接器通常要求具有高度可靠、耐磨損、抗振動、防腐蝕、低能耗、高環(huán)境適應(yīng)性等特點，以確保在高速移動及嚴(yán)苛工作條件下的穩(wěn)定、安全和高效運(yùn)行。 軌道交通應(yīng)用連接器可能包括各種類型，如鐵路車輛間的MVB（多功能車輛總線）連接器、供電系統(tǒng)的AC/DC電源插座、車鉤電路連接器、列車控制系統(tǒng)與地面設(shè)備的數(shù)據(jù)接口等。其設(shè)計需符合國際或行業(yè)標(biāo)準(zhǔn)，如IEC 62263（鐵路車輛連接器）、EN 50155（火車車輛電子設(shè)備通用要求）等，以確保整個軌道交通系統(tǒng)的互聯(lián)互通性和安全性。
