Description

  The present invention relates to a shielded connector that prevents intrusion and leakage of noise.

In electric vehicles and the like, a shielded wire is used as an electric wire because electromagnetic shielding is considered due to noise problems, and a shield connector is connected to the end of the electric wire. Connected to the connector. By fitting both the connectors, the core wire of the shielded wire and the terminals in the motor-side connector are electrically connected, and the braided shielded wire is electrically connected to the motor-side connector housing via the shield connector. To be shielded. And the following shield connector is known as what was trying to connect reliably and confirming a connection state. That is, in the connection structure of the shield connector in which one of the conductive connector housings and the other conductive connector housing are shield-connected when the two connectors are fitted, either one of the conductive connector housings is turnably conductive. The other connector housing is provided with an engaging portion that engages with the rotating lever and engages the shield connector by rotating the rotating lever, and / or the rotating lever and / or The other connector housing is provided with a conductive elastic contact portion that contacts the other connector housing and / or the rotation lever and elastically deforms when the rotation lever is rotated and the connector is fitted. It is known (see Patent Document 1). In such a conventional example, when the conductive rotation lever is rotated and the connector is fitted, the elastic contact portion contacts the other connector housing and / or the rotation lever and elastically deforms. Since the lever and the other connector housing are connected by elastic contact, the one conductive connector housing and the other conductive connector housing are reliably electrically connected. Further, since the rotation lever and the other connector housing are connected by elastic contact, the rotation lever does not rattle. For this reason, in the case where the rotating lever is provided with an elastic contact portion and in the case where the rotating contact portion is not provided, the rattling state of the rotating lever is different at the time of fitting. The connection state with the connector housing can be confirmed.

  In the above-described conventional example, the size of the rotating lever is considerably large, and thus a work space and a mounting space are required, and further, a signal detection connector for confirming the completion of the operation of the rotating lever is required. Since the lever release prevention portion of the connector prevents the release of the rotating lever, the number of parts is increased and the cost is increased.

  Therefore, the present invention aims to reduce the insertion force when the connectors are fitted to each other, does not use a conventional large lever, reduces the number of parts, saves space, and improves workability and connection reliability. An object is to provide a shielded connector.

  In order to achieve the above object, the present invention provides a shield connector in which both connectors are fitted so as to connect a plurality of terminals of a male connector and a female connector, and both the connectors are covered with a shield case. Protrusions are provided in each housing, and a long hole for rotation is formed in the shield case. A protrusion that moves in the long hole of the shield case and a protrusion of the housing of the female connector are inserted into the hole and the male A lever with a cam groove that engages with the projection of the housing of the connector is housed in a shield case, and the projection of the lever moves in the long hole by fitting the female connector to the male connector, and the hole serves as a fulcrum. The cam groove engages with the protrusion on the male housing, and this protrusion is pulled into the cam groove to insert the female connector into the male connector. It is.

The present invention is a shield connector in which both connectors are fitted so as to connect a plurality of terminals of a male connector and a female connector, and both the connectors are covered with a shield case.
Protrusions are provided in the housings of both connectors, and a long slot for rotation is formed in the shield case, and a protrusion that moves in the long hole of the shield case and a protrusion in the housing of the female connector are inserted to serve as a pivot fulcrum. And a lever with a cam groove that engages with the projection of the housing of the male connector is housed in the shield case. By fitting the female connector into the male connector, the projection of the lever moves through the long hole, thereby opening the hole. It rotates as a fulcrum, the cam groove engages with the protrusion of the male housing, this protrusion is pulled into the cam groove and the female connector is inserted into the male connector, so that the shield case operates in conjunction with the lever, The fitting force (insertion force) between the male connector and the female connector can be reduced, and workability is improved. Also, by sliding the shield case to match the position where it can be mounted on the connector mounting fixed panel and the position where both connectors are fully mated, it is possible to prevent incomplete mating of both connectors and improve connection reliability. Can do. Furthermore, since a large rotating lever is not attached to the outside, space can be saved.

  Preferred embodiments of the present invention will be described below with reference to the drawings.
