11、characteristics, the condition for qualification, acceptance and quality assurance for electrical and optical rectangular connectors with single or multiple removable rectangular inserts for use in a temperature range from 65 C to 175 C continuous for electrical contact. This family of connectors is

12、 particularly suitable for aeronautic use in zones of severe environmental conditions on board aircraft, applying EN 2282. Inserts for fiber optic contacts or mixing fiber optic contacts and electrical contacts are described in EN 4639-002. 2 Normative references The following documents, in whole or

The reference planes and axis used in this product standard are listed below: Ap : shell bottoming reference plane on male housi

20、ng. Ar : shell bottoming reference plane on female housing. Bp : vertical axis of male housing Br : vertical axis of female housing Cp : horizontal axis of male housing Cr : horizontal axis of female housing DAC: disconnect aligning housing cavity DNC: disconnect non aligning housing cavity N : extr

21、emity of insert retention clip reference plane P : front face of hard insert R : vertical axis of housing backshell interface RAC: rack rack and panel connectors. The current revision of this standard is describing 2 disconnect panel housing sizes and 3 rack and panel housing sizes. However, it is a

22、lso providing a design rule to extend the current range described. The design rule is based on the description of housing aligning cavities, housing non aligning cavities and a clinging dimension line; see 4.2 and 4.3 for details. These connectors have rectangular housings, removable rectangular ins

23、erts and contacts and can be fitted with rear accessories. Male and female inserts can be fitted either in the male or female housing. Depending on the housing size, the disconnect panel connectors are mated and unmated either by using a centre coupling screw or 2 quarter turn fasteners. The centre

24、coupling mechanism shall provide a total of 12 polarization positions. Housings having the quarter turn fasteners are polarized by using 2 polarizing posts and keys offering a total of 16 polarizing positions. A size 1 housing has 1 insert cavity with 1 keyway, quarter turn fasteners and 2 polarizin

25、g posts or keys. A size 2 housing has 2 insert cavities with one cavity having one keyway and the other having two keyways; a central coupling mechanism provides housing polarization. There are three rack and panel (blind mate) connector housing sizes; it is a size 2, size 3 and size 4 housing which

26、 have respectively 2, 3 and 4 insert cavities all with one keyway, three polarizing posts or keys offering 64 polarizing positions and no locking mechanism. In addition to this rack and panel use, the size 4 male connector can be mated with 2 size 2 female connector in a disconnect application by us

27、ing 2 centre coupling mechanism. These connectors use different types of contacts (signal, power, coaxial, triaxial, quadrax, etc) see EN 3155-002 and optical contacts see EN 4639-002. 4.2 Female housing 4.2.1 General For disconnect application, the following housings are described: size 1 housing h

28、as quarter turn fasteners and 2 polarization keys that can take 4 positions to polarize the housing. Size 1 female housing is panel mount connector. size 2 housing has a central coupling mechanism which can take 12 positions to polarize the housing. Size 2 female housing are either panel mount conne

29、ctor or cable connector. In addition, size 1 and 2 female housings are available with a grounding block (class B and F) or without a grounding block (class A, C and E) allowing grounding of a cable braid with a pigtail. prEN 4644-001:2015 (E) 6 For rack and panel application, the following sizes are

30、 described: size 2 housing has 3 polarization keys, each of them can take 4 positions to prevent mismating between male and female housing. size 3 housing has 3 polarization keys, each of them can take 4 positions to prevent mismating between male and female housing. size 4 housing has 3 polarizatio

31、n keys, each of them can take 4 positions to prevent mismating between male and female housing. Rack and panel female housing shall be installed on the aircraft side and are cable connectors. No grounding block option is available for rack and panel housings. The insert cavities are identified on th

32、e female housing by letters A, B, C, D for size 4, letters A, B, C for size 3 letters, A, B for size 2 and no letter for size 1. The insert cavities are polarized by either one (A polarizing position) or two keyways (B polarizing position) location. Housing size 1, 3 and 4 insert cavities have one k

33、eyway. Housing size 2 insert cavity identified with letter A has one keyway and insert cavity identified with letter B has two keyways. Each insert cavity has 2 insert retaining devices allowing rear insertion and rear release of the insert. Each female housing has a grounding device ensuring electr

34、ical continuity between housings before contact mating. For each female housing, some cavities are aligning cavities and other cavities are non-aligning. Aligning cavities guaranty not only the alignment between male and female housing but also guarantee the shell to shell bottoming. Non-aligning fe

35、male housing cavities have a circular location tolerance. In order to define how alignment of the female and male housing is achieved, a dimension line between the 2 housing aligning cavities is defined. prEN 4644-001:2015 (E) 7 4.2.2 Disconnect panel female housing alignment Key 1 Dimensions for ho

38、ing 4.3.1 General For disconnect application, the following housings are described: size 1 male housing has quarter turn fasteners and 2 polarization post that can take 4 positions to polarize the housing. Size 1 male housing is cable connector. size 2 male housing has a central coupling mechanism w

39、hich can take 12 positions to polarize the housing. Size 2 male housing is panel mount connector or cable connector. Size 1 and 2 male housings are available with (class B and F) or without grounding block (class A, C and E) allowing grounding of a cable braid with a pigtail. For rack and panel appl

40、ication, the following housings are described: size 2 male housing has three polarization posts, each of them can take 4 positions to prevent mismating between male and female housing. size 3 male housing has three polarization posts, each of them can take 4 positions to prevent mismating between ma

41、le and female housing. size 4 male housing has three polarization post, each of them can take 4 positions to prevent mismating between male and female housing. Male housing shall be installed on equipment side and can be connected to PCB or cable harness. No grounding block option is available for r

42、ack and panel housings. The insert cavities are identified on the male housing by letters A, B, C, D for size 4, letters A, B, C for size 3, letters, A, B for size 2 and no letter for size 1. The insert cavities are polarized by either one or two keyways location. Housing size 1, 3 and 4 insert cavi

43、ties have one keyway. Housing size 2 insert cavity identified with letter A has one keyway and insert cavity identified with letter B has two keyways. Each insert cavity has 2 insert retaining devices allowing rear insertion and rear release of the insert. All male housing have a minimum of 1 (for s

44、ingle cavity connectors) and a maximum of 2 aligning housing cavities (see Figure 5 and Figure 7); the remaining housing cavities are non-aligning cavities (see Figure 6 and Figure 8). This principle is not valid for size 4 male housing because it can be mated with 2 size 2 female housings. Aligning

45、 cavities guaranty not only the alignment between male and female housing but also guarantee the shell to shell bottoming. Non-aligning housing cavities have a circular location. In order to define how alignment of the female and male housing is achieved, a clinging dimension line between the 2 hous

46、ing aligning cavities is defined. prEN 4644-001:2015 (E) 12 4.3.2 Disconnect panel male housing Key 1 Dimension for housing size 1 2 Dimension for housing size n (n 1) Figure 5 Disconnect panel male aligning cavity (DAC) prEN 4644-001:2015 (E) 13 Figure 6 Disconnect panel male non-aligning cavity (D

48、omplete with contact retention systems and appropriate seals. The female inserts use female contacts and male inserts use male contacts. These inserts use contacts of size 22, 20, 16, 12, 5 and 8. The inserts are rear release rear removable from the housing. Male and female inserts can be installed

49、either in the male or female housing. There are inserts with one polarizing rib (A polarizing position) and inserts with two polarizing ribs (B polarizing position). This means that there are inserts dedicated to housing cavities with one keyway and inserts dedicated to housing cavities with two keyways.
