Description

The present invention relates to connectors.

Conventionally, a known connector includes a housing, terminals housed in the housing, and a retainer as a spacer assembled in the housing and engaged with the terminals to retain the terminals in the housing ( See Patent Document 1). The retainer is attached to the housing so as to be movable between a temporary locking position in which the terminals can be inserted into the housing and a full locking position in which the terminals accommodated in the housing are engaged.

Between the housing and the retainer, a temporary locking protrusion and a locking stepped portion are provided as a temporary locking portion for holding the retainer at the temporary locking position. Further, between the housing and the retainer, a final locking projection and a locking stepped portion are provided as a final locking portion for holding the retainer at the final locking position.

The retainer is held at a temporary locking position with respect to the housing by the engagement between the temporary locking projection and the locking stepped portion and the contact between the final locking projection and the locking stepped portion. When the retainer shifts from the temporary locking position to the final locking position, the final locking projection slides over the locking stepped portion, and the final locking projection climbs over the locking stepped portion to achieve the final locking. A projection is engaged with the locking step. The retainer is held at the final locking position with respect to the housing by the engagement between the final locking projection and the locking stepped portion.

In such a connector 101, the guide portion 41 is elastically deformed by the movement of the spacer 7 from the temporary locking position to the final locking position, and is restored from the elastic deformation to function as an elastic arm that moves the spacer 7. It has a locking arm 33 . Therefore, the spacer 7 can be moved by the elastic deformation force of the temporary locking arm 33, and the main locking projection 35 and the final locking projection 37 can be stably engaged.

Although the present embodiment has been described above, the present embodiment is not limited to these, and various modifications are possible within the scope of the gist of the present embodiment.

For example, the temporary locking arms are elastically deformable, but they do not have to be elastically deformable. In this case, when the spacer is inserted into the spacer accommodating portion and arranged at the temporary locking position, a guiding portion may be provided to move the spacer and engage the projection to be temporarily locked with the projection to be temporarily locked. preferable. In addition, by preventing the main locking arm from elastically deforming, the rigidity of the spacer can be increased, and breakage of the spacer can be suppressed.

Further, the guide surface is an inclined surface, but it is not limited to this, and may be a curved surface or the like. The guide surface may have any shape as long as it can be shaped.
