Connector View Identification

Electrical wiring connectors can he classified according to the type of terminals (such as pin terminals or flat terminals), the number of poles (terminals), whether they are male or female, whether they have a locking device or not, etc... In this Electrical Wiring Manual, connectors will generally be classified as follows:





1. Identification of Terminal Type

Generally, the connectors illustrated with oblique top corners indicate the pin terminal connectors, whereas the connectors illustrated with stepped top corners indicate the flat terminal connectors.

Some connectors with oblique top corners have an X-marked section. These indicate the small-size flat terminal connectors in which the section marked X indicates the position of a guide provided to prevent improper connection.

A blackened section also indicates the position of a guide provided to prevent improper connection.

2. Identification of Number of Poles

The number of sections of a connector represents the number of poles in the connector. If the connector has X-marked or blackened sections, such sections are not counted as poles.

The connector shown in illustration at right has 18 sections. Since the blackened sections are not counted as poles, the number of poles of the connector is 16.





3. Identification of Male and Female Connectors

Connectors illustrated with double outer lines are male, and those with single outer lines are female.

4. Identification of Locking Device

If a flat terminal connector is illustrated with a projection at the top, it indicates that the connector is equipped with a locking device.

NOTES:

1. All pin terminal connectors, small flat terminal connectors and sealed connectors are equipped with locking devices. So no symbol for identification of a locking device is shown in the illustrations.

2. The housing lance lock type connector is a connector with a lance in the connector housing. The lance assures tighter locking of the terminals and prevents the terminals from coming out of position, offering higher reliability.





5. Identification of Sealed Connectors

Identification of round sealed connectors (water-proof pin terminal connectors) used for the igniter (turbo vehicles), pop-up motor, etc... is accomplished by the same method as described above.





6. Identification of Connector Terminals

The color codes of a pair of connectors (male and female), if viewed at their joining surfaces, will appear symmetrical. When the connectors are connected, however, their joining surfaces are put together in the way a book is closed, so the terminals of the identical codes are connected together.

NOTE: The color codes of male and female connectors are not always identical.
