  By the way, if you want to remove the terminal fitting from the terminal housing for maintenance reasons, remove the hood from the terminal housing and expose the lance to the outside, then use a jig to It is necessary to remove the terminal fitting by bending the wire. However, for example, when the terminal accommodating portion is pulled out in an oblique direction with respect to the insertion direction in which the contact portion of the terminal fitting is inserted into the insertion hole, the contact portion may be damaged due to strong contact with the inner wall of the insertion hole. .

  As a countermeasure for this, for example, a method of inserting a jig from the hole by providing a hole for inserting a jig in the back wall of the hood instead of removing the hood from the terminal housing may be considered. However, in the connector having the hood portion, when the mating connector enters the hood portion in a tilted posture, the hood portion is formed long so that the mating connector does not contact the contact portion. In addition to making it difficult to insert the tool, the jig may come into contact with the contact portion during insertion, and the contact portion may even be damaged.

  The present invention has been completed based on the above circumstances, and prevents the terminal fitting from being damaged when the lance is bent using a jig to remove the terminal fitting from the terminal accommodating portion. Objective.

And a lance to be held by the connector, the terminal fitting can be released by bending the lance with a jig, and the housing intersects the mating direction with the mating connector. It is characterized in that it is configured to include a rotation mechanism portion that rotates the terminal accommodating portion in the direction so that the lance faces the outside.

  According to such a configuration, the lance can be exposed to the outside by rotating the terminal accommodating portion by the rotation mechanism portion. Thereafter, the terminal fitting can be removed from the terminal accommodating portion by inserting a jig toward the lance and bending the lance with the jig. Moreover, since it is not necessary to insert a jig | tool from the front of a hood part, damage to a terminal metal fitting can be prevented.

The following configuration is preferable as an embodiment of the present invention.
The housing may include a guide portion that guides the terminal accommodating portion in a direction away from the hood portion, and the terminal accommodating portion may be configured to rotate by the rotation mechanism portion after being separated from the hood portion by the guide portion.
For example, when a male terminal having a tab or the like is used as a terminal fitting, it is necessary to rotate the terminal accommodating portion after pulling out the tab from the hood portion. According to said structure, since a terminal accommodating part can be spaced apart from a hood part by a guide part, when rotating a terminal accommodating part by a rotation mechanism part, it can avoid that a terminal metal fitting and a hood part interfere.

A terminal accommodating part is good also as a structure which is guided in the state pinched | interposed from both sides by a pair of guide part, and rotates in the state pivotally supported from both sides by a pair of rotation mechanism part.
According to such a configuration, since the terminal accommodating portion can be sandwiched from both sides by the pair of guide portions, the terminal accommodating portion can be guided in a stable posture. Further, since the terminal accommodating portion can be pivotally supported from both sides by the pair of rotation mechanism portions, the terminal accommodating portion can be stably rotated.

The guide portion is configured to include a guide groove extending in a direction in which the terminal accommodating portion is separated from the hood portion, and an escape groove continuously provided at the end portion of the guide groove, and the rotation mechanism portion is accommodated in the guide groove. It is good also as what is provided with the rotating shaft pivotally supported by the termination | terminus part of the guide groove, and the protrusion accommodated in an escape groove | channel by rotation operation | movement centering on a rotating shaft.
According to such a configuration, the terminal housing portion can be guided in a direction away from the hood portion by the rotation shaft entering the guide groove. Further, when the rotation shaft reaches the end portion of the guide groove, the protrusion enters the escape groove, so that the terminal accommodating portion can be rotated around the rotation shaft.

The guide groove has a configuration in which a first guide groove that accommodates the rotation shaft and a second guide groove that accommodates the protrusion are juxtaposed, and the escape groove is continuously provided at the end portion of the second guide groove. It is good also as a structure.
According to such a configuration, the terminal housing portion can be stably guided in the direction away from the hood portion by causing the rotating shaft to enter the first guide groove and the protrusion to enter the second guide groove. Further, since the second guide groove connected to the escape groove is formed separately from the first guide groove, it is possible to prevent the rotation shaft from entering the escape groove by mistake.

The rotation mechanism is configured to include a holding protrusion that holds the terminal accommodating portion at a predetermined rotation angle by being fitted and locked in the first guide groove by a rotation operation around the rotation axis. Also good.
According to such a configuration, by holding the holding projection in the first guide groove, the terminal accommodating portion can be held at a predetermined rotation angle, and the jig can be easily inserted toward the lance.
