The current revision of this standard is describing 2 disconnect panel housing sizes

30、and 1 rack and panel housing size. However, it is also 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 h

31、ave rectangular housings, removable rectangular inserts 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 coup

32、ling screw or 2 quarter turn fasteners. The centre coupling screw and coupling nut can be installed either on the male or female housing. The centre coupling mechanism shall provide a total of 12 polarization positions. Housings having the quarter turn fasteners are polarised by using 2 polarizing p

33、osts and keys offering a total of 16 polarizing positions. A size 1 housing has 1 insert cavity with 1 keyway, a quarter turn fastener and 2 polarizing 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 mechani

34、sm provides housing polarization.

35、 3 insert cavities all with one keyway, three polarizing posts or keys offering 64 polarizing positions and no locking mechanism. These connectors use different types of contacts (signal, power, coaxial, triaxial, quadrax, etc.) defined in EN 3155-002 and optical contacts defined in EN 4639-101 and

36、EN 4639-102. 4.2 Female housing 4.2.1 General Size 1 and 3 female housings 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 4 pins, each of which can take 2 positions, to polarise the shell wit

37、h the panel on which it is mounted. Size 2 female housing are either panel mount connector 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 for size 3 lett

38、ers A, B for size 2 and no letter for size 1. The insert cavities are polarizsed by either one (A polarizing position) or two keyways (B polarizing position) location. Housing size 1 and 3 insert cavities have one keyway. Housing size 2 insert cavity identified with letter A has one keyway and inser

39、t 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 electrical continuity between housings before contact mating. In addition, size 1 and 2 fem

40、ale 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. 4.2.2 Disconnect panel female housing All disconnect panel female housing have a minimum of 1 (for single cavity connectors) and a maximum of 2 alig

41、ning housing cavities (see Figure 1); the remaining housing cavities are non aligning cavities (see Figure 2). 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 2 housing a

42、ligning cavities is defined.
