Guiding System
(See pages 8 to 11)
The 801 and 801CX Series of two part p.c. connectors incorporate a wide choice of polarising and guiding facilities. Since their original introduction these facilities have been extended and improved such that currently the following options are available:
- Hexagonal
l.f. and combined l.f./h.f. connectors with polarised guides which can be orientated to any one of six angular positions of 60°. This permits a choice of 36 positions for each connector. Connectors fitted with 72, 84 or 96 l.f. contacts have an additional central guide, normally plain but a polarised guide may also be fitted which in these sizes provides 216 polarising positions.
Alternatively the complete range of connectors may be fitted with unpolarised guides, jackscrews or quarter turn locking guides, the latter having four preferred polarising positions, namely F6, D2, C5 and A5.
- Quadrangular
Combined l.f./h.f. connectors with polarised guides which can be orientated to any one of four angular positions of 90°. This permits a choice of 16 positions for each connector.
Alternatively the complete range of connectors may be fitted with unpolarised guides or jackscrews.
Connector Styles and Contact Cavity Identification
Style and contact identification is determined by the application of
Fixed or
Free to the connector.
Where option (a) is chosen, i.e., hexagonal guides are used the following definitions are applicable.
A
Fixed connector is rack or motherboard mounted, has
female guides and male or female contacts. The l.f. contact cavity identification is by numbers from
right to left and (where fitted) h.f. contact cavity identification is by numbers from left to right. This applies when viewing the mating face with the reference plane at the base.
A
Free connector is rack or motherboard mounted, has
male guides and male or female contacts. The l.f. contact cavity identification is by numbers from
left to right and (where fitted) h.f. contact cavity identification is by numbers from right to left. This also applies when viewing the mating face with the reference plane at the base.
A
Coupler connector replaces a Fixed connector in a daughter-to-daughter board mounted application has
female guides and male or female contacts. The l.f. contact cavity identification is by numbers from
right to left and (where fitted) h.f. contact identification is by numbers from left to right. This similarly applies when viewing the mating face with the reference plane at the base.
Connectors are supplied with guides polarised at positions A and 1 or quarter turn locking guides polarised at positions F and 6 in the unlocked condition.
The above are the preferred styles but connectors can also be supplied with
male guides in
fixed connectors and
female guides in
free connectors. These are
reverse contact identification and are non-preferred.
Where option (b) is chosen, i.e. quadrangular guides are used in combined l.f./h.f. connectors the following definitions are applicable.
A
Fixed connector is fitted with a
male l.f. and h.f.
contacts and either male or female guides. The l.f. contact cavity identification is by numbers from
right to left and h.f. contact cavity identification is by numbers from left to right. This applies as previously when viewing the mating face with the reference plane at the base.
A
Free connector is fitted with a
female l.f. and h.f.
contacts and either male or female guides. The l.f. contact cavity identification is by numbers from
right to left and h.f. contact cavity identification is by numbers from right to left. This again applies when viewing the mating face with the reference plane at the base.
A
Coupler connector is fitted and marked the same way as a
Fixed connector. Guides are fitted and polarised at positions A and 1.
When combined l.f./h.f. connectors are used all contacts in a connector help should be of the same gender.
