EN 4644-001:2017 (E) 6 4 Description 4.1 General This family of connectors is divided into two types of connectors which are the following:  disconnect panel connectors;  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 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 have 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 coupling screw or 2 quarter turn fasteners. The centre 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 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 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 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 using 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 has 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 connector or cable connector.
SIST EN 4644-001:2018



EN 4644-001:2017 (E) 7 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. For rack and panel application, the following sizes are 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 polarization 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 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 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 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. Each female housing has a grounding device ensuring electrical 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 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 aligning cavities is defined. SIST EN 4644-001:2018

EN 4644-001:2017 (E) 12 4.3 Male housing 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 which 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 application, 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 male 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 rack 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 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 2 insert retaining devices allowing rear insertion and rear release of the insert. All male housing have a minimum of 1 (for single 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 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 housing aligning cavities is defined. SIST EN 4644-001:2018

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 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. See Table 1 below. SIST EN 4644-001:2018

A blank insert is installed in a housing cavity where no contact is required. This blank insert has no polarizing rib and the same dimensions as an insert for pin contacts. It can be installed in any male or female housing cavity. This blank insert can mate without causing any interference with an insert for male contacts or with an insert for female contacts. The blank insert does not provide sealing. 4.6 Keying mechanism Keying mechanism for disconnect connectors:
Size 1 housings have a polarizing system using polarizing posts having a L shape cross section and polarizing keys having a L shape cavity to mate with the polarizing posts. Each polarizing post and key provides 4 polarizing positions. Each post and key is retained in the housing by a special shape which allows them to be clipped in the housing. Size 1 housings have 2 polarizing pins offering 16 polarizing positions.
The size 2 housing has either a centre coupling screw or coupling nut which ensures also the polarizing function. The coupling screw has a coding peg and the coupling nut has a coding slot. The centre coupling screw and nut have an hexagonal shoulder which slides in an hexagonal print in the housing, consequently, the coupling screw or nut can take 6 positions. The coding peg on the coupling screw and the slot on the coupling nut can be vertically aligned with an angle or a flat of the hexagonal shoulder. There are 2 types of coupling screw and coupling nut, those having the coding peg or the slot aligned with a flat and those for which it is aligned with an angle of the hexagonal shoulder. These 2 types of coupling screw and nut provide a total of 12 polarizing positions. Keying mechanism for rack and panel connectors: Size 2, 3 and 4 housings have a polarizing system using polarizing posts having a L shape cross section and polarizing keys having a L shape cavity to mate with the polarizing posts. Each polarizing post and key provides 4 polarizing positions. Each post and key is retained in the housing by a special shape which allows them to be clipped in the housing.
