CN-122026167-A - Lever type connector

Abstract

The invention provides a lever type connector, which can inhibit the locking of a locking arm from being released even if an unexpected external force is applied to a lever at an initial position by the locking arm. The lever-type connector (1) is provided with a housing (3), a retainer (5) that accommodates the housing, and a lever (6) that is pivotally supported by the housing and that rotates relative to the housing, the lever having a plate-shaped lever body (61A) that enters between the housing and the retainer, a locking arm (65) that is provided to the lever body so as to be able to be locked with an end edge (57) of the retainer, a displacement restricting portion (66) that restricts displacement of the locking arm, the locking arm having an arm (65A) that is provided by cutting out the lever body, and a locking projection (65B) that is provided so as to protrude from a free end of the arm and that is able to be locked with the end edge of the retainer, the displacement restricting portion having a receiving surface (66A) that is configured to be inclined so as to protrude toward the locking arm as to advance in a direction (Z2) in which the locking projection and the end edge of the retainer are released.

1. 1. A lever type connector, characterized by comprising: A housing; A holder accommodating the housing, and A lever that is pivotally supported to the housing and rotates relative to the housing, wherein, The lever includes a plate-shaped lever body that is interposed between the housing and the holder, a locking arm that is provided to the lever body and that can be locked with an end edge of the holder, and a displacement restricting portion that restricts displacement of the locking arm, The locking arm includes an arm provided by cutting the lever body, and a locking protrusion provided protruding from a free end of the arm and capable of locking with an end edge of the holder, The displacement limiting part is provided with a bearing surface which can be abutted with the locking arm when the locking arm is displaced, The receiving surface is inclined so as to protrude toward the locking arm as it goes in a direction in which the locking of the locking protrusion with the end edge of the retainer is released.

Description

Lever type connector Technical Field The present invention relates to lever type connectors. Background A lever type connector is known in which a lever is rotatably supported on a connector body holding terminals, and a counterpart connector is brought close to the connector body in which the lever rotates and is fitted with the connector body (for example, see patent document 1). Fig. 9 is a front view showing a conventional lever type connector 101. The lever type connector 101 includes a connector body 102 to be fitted to a counterpart connector (not shown) and a lever 103 to be fitted to the counterpart connector by bringing the connector body 102 close to the counterpart connector in response to rotation. The connector body 102 is configured to have an inner housing 104 accommodating a plurality of female terminals and a front cover 105 accommodating the inner housing 104. The lever 103 is configured to have a door-shaped structure including a pair of side plates 103A sandwiching the inner case 104 and a connecting plate (not shown) connecting the pair of side plates 103A. The side plate 103A of the lever 103 is provided with an engagement arm 103D engaged with the opening inner edge 105a of the front cover 105. The locking arm 103D is locked to the opening inner edge 105a of the front cover 105, thereby restricting the rotation of the lever 103 and maintaining the lever 103 at the initial position. In a state where the lever 103 is in the initial position, the lever-type connector 101 is shipped and transported. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2021-125403 Disclosure of Invention Problems to be solved by the invention However, in the conventional lever-type connector 101, when an unexpected external force acts on the lever 103 during conveyance, the locking arm 103D is displaced in response to the rotation of the lever 103, and the amount k of engagement of the locking arm 103D with the opening inner edge 105a is reduced, making it difficult to maintain the lever 103 in the initial position. The invention provides a lever type connector, which can inhibit the locking of a locking arm from being released even if an unexpected external force is applied to a lever at an initial position by the locking arm. Means for solving the problems In order to solve the above-described problems, the lever-type connector according to the present invention includes a housing, a holder that accommodates the housing, and a lever that is pivotally supported by the housing and is rotatable with respect to the housing, wherein the lever includes a plate-shaped lever body that enters between the housing and the holder, a locking arm that is provided to the lever body and is lockable with an end edge of the holder, and a displacement restricting portion that restricts displacement of the locking arm, the locking arm includes an arm that is provided by cutting the lever body, and a locking projection that protrudes from a free end of the arm and is lockable with an end edge of the holder, and the displacement restricting portion includes a receiving surface that is contactable with the locking arm when the locking arm is displaced, the receiving surface being configured to be released from the locking projection in a direction that protrudes forward of the locking projection toward the locking edge of the holder. Effects of the invention According to the first aspect of the invention, even when an unexpected external force is applied to the lever in the initial position through the lock arm, the lock of the lock arm can be suppressed from being released.
