Description

  The technology disclosed in this specification relates to a connector.

  In connectors used in wire harnesses for automobiles, etc., in order to maintain the connection stability between the female terminal and the male terminal, the elastic contact piece of the female terminal comes into contact with the male terminal with a predetermined contact pressure. Designed to. Conventionally, the male terminal has been inserted so as to spread the elastic contact piece of the female terminal, so that when the connector is fitted, insertion resistance due to friction with the elastic contact piece acts on the male terminal. There has been a concern that the fitting operation becomes difficult due to the insertion resistance.

  Thus, for example, Patent Document 1 below describes a connector that can insert a male terminal with a small operating force by pressing down an elastic contact piece when the male terminal is inserted. In this connector, the elastic contact piece of the female terminal is connected by a connecting piece at the rear end portion, and a pressed portion is provided at the center of the connecting piece. On the other hand, the spacer that is inserted into the connector housing from the side perpendicular to the insertion direction of the female terminal is provided with a pressing portion that presses the pressed portion of the female terminal. Then, by inserting the spacer into the connector housing, the pressing portion comes into surface contact with the pressed portion, and the elastic contact piece is pressed down. Since the male terminal is inserted into the female terminal in this state, the male terminal can be inserted with a small operating force with almost no contact with the elastic contact piece. Then, by moving the spacer after the male terminal is completely inserted, the pressing to the pressed part by the pressing part is released, the elastic contact piece is elastically restored and contacts the male terminal, and the female terminal and the male terminal The contact pressure between the two can be ensured.

JP 2002-8797 A

  However, in the connector as in Patent Document 1, the number of parts such as spacers and connecting pieces increases, and the number of work steps also increases.

  The technology disclosed in the present specification has been completed based on the above circumstances, and an object thereof is to provide a connector with a simple configuration in which a male terminal can be inserted into a female terminal with a small force.

  The connector disclosed in this specification is a connector including a male connector having a male terminal and a female connector having a female terminal into which the male terminal can be inserted, the male terminal being connected to the female terminal. The female terminal has two contact pieces that can be brought into contact with the tab piece and at least one of which can be elastically deformed, and the elastic contact piece in the initial state as another contact piece. A locking piece that is elastically deformed so as to be separated from the contact piece, and the male connector presses the locking piece when the tab piece reaches the contact position. A pressing piece for releasing the locking of the elastic contact piece is provided, and the two contact pieces contact the tab piece in a state where the tab piece reaches the contact position.

According to the above configuration, the tab piece is inserted in a state (initial state) in which at least one of the two contact pieces of the female terminal is locked to the locking piece and the interval between the contact pieces is widened. Therefore, the operating force when inserting the male terminal can be reduced. When the tab piece is inserted and reaches a predetermined contact position, the elastic contact piece is unlocked and elastically restored to bring the male terminal tab piece and the female terminal contact piece into contact with each other with a predetermined contact pressure. be able to. In other words, in this specification, the contact position refers to a position where the engagement between the engagement piece and the elastic deformation piece is released, and the contact piece of the female terminal contacts the tab piece of the male terminal. Means the state before the tab piece is inserted and the contact position is reached. The contact position can be adjusted to an arbitrary position by changing the dimensional shape of the tab piece, the contact piece, the locking piece, the pressing piece, and the like.
In addition, according to the above configuration, the unlocking operation of the elastic contact piece and the locking piece is performed by the pressing piece, not the tab piece that is electrically connected to the female terminal. Etc. can be suppressed and the occurrence of poor connection can be suppressed.

  The connector which this specification discloses WHEREIN: The said elastic contact piece may be latched in the said initial state, leaving a space | interval larger than the thickness dimension of the said tab piece between the said other contact pieces.

  According to the above configuration, when inserting the male terminal, it is possible to insert the tab piece between the two contact pieces with almost no contact with the two contact pieces, thereby extremely reducing the operating force when inserting the male terminal. be able to.

  Further, in the connector disclosed in the present specification, the locking piece includes a locking portion that locks the elastic contact piece, and a displacement portion that is pressed by the pressing piece to displace the locking portion. A release portion that releases the locking of the contact piece may be formed.

  According to the said structure, latching with an elastic contact piece and a latching piece can be cancelled | released reliably. Here, since the pressing piece is configured to press the release portion, not the locking portion that holds the elastic contact piece in the locking piece, the elastic contact piece that is in electrical contact with the male terminal is the pressing piece. And the deformation of the elastic contact piece due to the releasing operation is suppressed, and the occurrence of poor connection can be suppressed.

  In the connector disclosed in this specification, only one of the two contact pieces may be the elastic contact piece.

  According to the said structure, since the conventional structure can be utilized as the other fixed contact piece, a connector with a small operating force when inserting a male terminal can be obtained with a simple structure. For example, in a conventional female terminal including a portion formed in a cylindrical shape or the like, a part of the side wall portion may be another contact piece that faces the elastic contact piece.

  Moreover, the connector which this specification discloses WHEREIN: The two said contact pieces may be made into the said elastic contact piece which both can elastically deform.

  According to the above configuration, after the male terminal is inserted, both the two contact pieces are elastically restored and elastically contact the tab piece, so that the male terminal and the female terminal are brought into contact with each other with a larger contact pressure. In addition, a connector having excellent connection stability can be obtained.

  Further, in the connector disclosed in the present specification, the elastic contact piece is formed with a movable contact portion that protrudes to a side in contact with the tab piece, and the tab piece reaches the contact position. In this state, a concave portion is formed at a position corresponding to the movable contact portion, and the movable contact portion of the elastic contact piece has the tab piece within the concave portion when the tab piece reaches the contact position. May be configured to come into contact.

  According to the said structure, when the latching of an elastic contact piece is cancelled | released, a movable contact part will be displaced with the elastic restoration of an elastic contact piece, and will contact a tab piece. At this time, since the movable contact portion is fitted in the recess and contacts the tab piece, positional displacement and the like are prevented, and a connector having excellent connection stability can be obtained.

  In the connector disclosed in the present specification, the male connector may include a male connector housing that holds the male terminal, and the pressing piece may be provided in the male connector housing.

  According to the above configuration, by providing the pressing piece in a predetermined position of the male connector housing in advance, it is not necessary to align the pressing piece when inserting the male terminal, and it is elastic only by moving the male connector toward the female connector. The locking of the contact piece can be released, and the workability is improved. Further, since the pressing piece can be provided in the male connector housing together with the male terminal, the situation where the male terminal and the pressing piece interfere with other members and the like is suppressed, and the occurrence of problems due to deformation and the like can be reduced.

  Further, in the connector disclosed in the present specification, the male connector includes a retainer that is attached from the side inserted into the female terminal and fixes the male terminal, and the pressing piece is provided on the retainer. May be.

  According to the said structure, this technique is applicable also to the connector which attached the retainer.

  ADVANTAGE OF THE INVENTION According to this invention, the connector which can insert a male terminal in a female terminal with a small force can be provided.
