Abstract
A male connector (M) has male housings (20A, 20B, 20C) and is connectable with a female connector (F) with female housings (40A, 40B, 40C). Error connection preventing projections (28A, 28B) of the male housings (20A, 20B) are received in receiving portions (47A, 47B) of the female housings (40A, 40B) to connect the two connectors (M, F) properly if the combination of the housings in the male and female connectors (M, F) is correct. However, the error connection preventing projections (28A, 28B) on the male housings (20A, 20B) interfere with opposed the female housings (40B, 40C) and hinder connection of the two connectors (M, F) if the combination of housings is incorrect.
Claims5
A split-type connector assembly, comprising:
- a first connector including a first frame with first accommodating chambers and a plurality of kinds of first auxiliary connector housings accommodated in the respective first accommodating chambers;
- a second connector including a second frame with second accommodating chambers and a plurality of kinds of second auxiliary connector housings accommodated in the respective second accommodating chambers;
- and
- at least one error connection preventing means between the first auxiliary connector housings and the corresponding second auxiliary connector housings and adapted to permit proper connection of the first and second connectors if the auxiliary connector housings of corresponding kinds are opposed to each other, wherein the error connection preventing means comprise error connection preventing projections projecting substantially in a connecting direction from the first auxiliary connector housings and having different shapes depending on the kinds, and corresponding receiving portions formed in the second auxiliary connector housings for receiving only the error connection preventing projections of the first auxiliary connector housings of the corresponding kinds.
A method of assembling a split-type connector assembly, comprising:
- providing a first connector including a first frame formed with accommodating chambers;
- accommodating a plurality of kinds of first auxiliary connector housings in the respective accommodating chambers of the first connector;
- providing a second connector including a second frame formed with accommodating chambers;
- accommodating a plurality of kinds of second auxiliary connector housings in the respective accommodating chambers;
- engaging the first and second connectors with each other;
- and
- detecting if the auxiliary connector housings of uncorresponding kinds are opposed to each other upon connection by means of error connection preventing means between the auxiliary connector housings, wherein the error connection preventing means project substantially in a connecting direction from the first auxiliary connector housings and have different shapes depending on the kinds, and corresponding receiving portions formed in the second auxiliary connector housings for receiving only the error connection preventing projections of the first auxiliary connector housings of the corresponding kinds, and
- wherein proper connection of the two connectors is permitted by the error connection preventing projections being received into the corresponding receiving portions if the auxiliary connector housings of corresponding kinds are opposed to each other while being hindered by the error connection preventing projections interfering with the second auxiliary connector housings if the auxiliary connector housings of uncorresponding kinds are opposed to each other.
