18、n The connectors defined by this standard are suitable for use on board of commercial and military aircraft for both disconnect panel and rack and panel applications in severe environmental conditions. 1 Scope This European Standard specifies the required characteristics, the condition for qualifica

19、tion, 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 particularly suitable for aeronautic use in

20、 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 in part, are normatively referenced in this

27、 for 2)3 Terms and definitions For the purposes of this document, the definitions given in EN 2591-100 apply. The reference planes and axis used in this product standard are listed below: Ap : shell bottoming reference plane on male housing. Ar : shell bottoming reference plane on female housing. Bp

28、 : 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 : extremity of insert retention clip reference plane P : front face

29、of hard insert R : vertical axis of housing backshell interface RAC: rack rack and panel connectors. The current revision of this standard is describing two disconnect panel housing sizes and one rack and panel housing size. However, it is also providing a design rule to extend the current range des

30、cribed. 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 inserts and contacts and can be fitted with rear accessories.

31、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 two quarter turn fasteners. The centre coupling screw and coupling nut can be installed either o

32、n the male or female housing. The centre coupling mechanism shall provide a total of 12 polarization positions. Housings having the quarter turn fasteners are polarized by using two polarizing posts and keys offering a total of 16 polarizing positions. A size 1 housing has one insert cavity with one

33、 keyway, a quarter turn fastener and two polarizing posts or keys. A size 2 housing has two insert cavities with one cavity having one keyway and the other having two keyways; a central coupling mechanism provides housing polarization. There is two rack and panel (blind mate) connector housing sizes

34、; it is a size three housing and a size four housing which have respectively three and four 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 four male connector can be mated

35、 with two size 2 female connectors in a disconnect application by using two centre coupling mechanisms. These connectors use different types of contacts (signal, power, coaxial, triaxial, quadrax, etc.) see EN 3155-002 and optical contacts see EN 4639-002. BS EN 4644-001:2012EN 4644-001:2012 (E) 7 4

36、.2 Female housing 4.2.1 General Size 1 and 3 female housing shall be attached by rectangular flange with two mounting holes, size 3 housing has floating eyelet mounting holes or through holes. The size 3 housing has four pins, each of which can take two positions, to polarize the shell with the pane

37、l on which it is mounted. Size 4 female housing shall be attached by rectangular flange with two or three mounting holes, Size 4 housing has four pins, each of which can take two positions, to polarize the shell with the panel on which it is mounted. Size 2 female housing are either panel mount conn

38、ector or cable connector. Panel mount receptacle connector shall be attached by rectangular flange with two mounting holes. The insert cavities are identified on the 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 ins

39、ert 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 keyway. Housing size 2 insert cavity identified with letter A has one keyway and insert cavity identified with letter B has two keyways.

40、Each insert cavity has two insert retaining devices allowing rear insertion and rear release of the insert. Each female housing has a grounding device ensuring electrical continuity between housings before contact mating. In addition, size 1 and 2 female housings are available with a grounding block

41、 (classes B and F) or without a grounding block (classes A, C and E) allowing grounding of a cable braid with a pigtail. 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

42、 but also guarantee the shell to shell bottoming. Non aligning female 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 two housing aligning cavities is defined. BS EN 4644-001:2012EN 4644-001

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 cav

47、ities are polarized by either one or two keyways location. Housing size 1, 3 and 4 insert cavities 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 two insert retaining devices all

48、owing rear insertion and rear release of the insert. Size 1 and 2 male housings are available with (classes B and F) or without a grounding block (classes A, C and E) allowing grounding of a cable braid with a pigtail. All male housing have a minimum of one (for single cavity connectors) and a maxim

49、um of two aligning housing cavities (see Figure 5 and Figure 7); the remaining housing cavities are non aligning cavities (see Figure 6 and Figure 8). Aligning 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 two h
