CN-122026166-A - Connector unit

Abstract

The invention provides a connector unit which improves the operation efficiency of connector fitting operation and suppresses the bad condition related to the fitting of the counterpart connector. The connector unit (20) is provided with a mating connector (11), a connector body (10), and a lever (6) pivotally supported by the connector body (10), wherein the lever (6) is rotatably provided to an initial position (6A) and a rotation completion position (6B), and has a pair of arm plates (61A, 61B) and a connecting portion (62) connecting the pair of arm plates (61A, 61B) to each other, a locking projection (66C) for locking the mating connector (11) in the rotation completion position is provided on one (61A) of the pair of arm plates (61A, 61B), the connecting portion (62) has an abutment surface (620) for abutting against the mating connector (11) in the rotation completion position, and the abutment surface (620) is configured to be inclined such that a root portion (62B) of the other one (61B) of the pair of arm plates is located farther from the mating connector (11) than a root portion (62A) of the one (61A).

Claims (1)

1. 1. A connector unit, characterized in that, The connector unit includes a mating connector and a connector body that can be fitted to each other, and a lever pivotally supported by the connector body and rotatable relative to the connector body, The lever is provided so as to be rotatable to an initial position and a rotation completion position where the counterpart connector is brought close to the connector body and fitted, The lever has a pair of arm plates disposed opposite to each other and sandwiching the connector body, and a coupling portion coupling the pair of arm plates to each other, A locking portion that locks the counterpart connector at the rotation completion position is provided at one of the pair of arm plates, The connecting portion has an opposing surface capable of opposing and abutting the counterpart connector in the rotation completion position, The opposing surface is configured to have an inclination such that a root portion of the other of the pair of arm plates is located farther from the counterpart connector than the root portion of the one of the pair of arm plates.

Description

Connector unit Technical Field The present invention relates to a connector unit. Background A lever type connector is known in which a lever is rotatably supported by a connector body holding terminals, and a counterpart connector is fitted close to the connector body as the lever rotates (for example, see patent document 1). Fig. 7 is a diagram showing a conventional lever connector 101. The lever type connector 101 includes a connector body 102 that is fitted to a counterpart connector (not shown), a lever 103, and a locking portion 103A that is provided on the lever 103 and that is locked to the counterpart connector when the counterpart connector is fitted to the connector body 102. The lever 103 has a door-shaped structure including a pair of arm portions 103B (only one of the pair of arm portions is shown) facing each other and an operation portion 103C connecting the pair of arm portions 103B, and when the lever 103 is rotated to engage the mating connector with the connector body 102, the engagement portion 103A provided in one of the pair of arm portions 103B engages the mating connector, thereby maintaining the engagement state of the mating connector with the connector body 102. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2023-109418 Disclosure of Invention Technical problem to be solved by the invention However, when the lever 103 is of a door type, the operator may operate the lever 103 by gripping a biased position without gripping a position where the force acts equally on the pair of arm portions 103B. In such a case, the lever 103 is deformed so as to be twisted by the operator's operation force not being uniformly transmitted to the pair of arm portions 103B, and the operation portion 103C interferes with the mating connector before the mating connector is locked by the locking portion 103A provided in one arm portion 103B of the pair of arm portions 103B, so that the mating connector cannot be further pushed in, and the mating connector cannot be locked by the locking portion 103A, that is, the mating connector cannot be maintained in the fitted state with the connector main body 102, that is, a state in which there is a problem associated with the fitting of the mating connector. The invention provides a connector unit which can improve the operation efficiency of the fitting operation of a connector and inhibit the defect related to the fitting of a counterpart connector. Means for solving the problems In order to solve the above-described problems and achieve the object, the invention described in claim 1 is a connector unit including a mating connector and a connector main body that can be fitted to each other, and a lever that is pivotally supported by the connector main body and is rotatable with respect to the connector main body, the lever being provided so as to be rotatable to an initial position and a rotation completion position in which the mating connector is brought close to the connector main body and is fitted, the lever having a pair of arm plates that are provided so as to face each other and sandwich the connector main body, and a connecting portion that connects the pair of arm plates to each other, one of the pair of arm plates being provided with a locking portion that locks the mating connector in the rotation completion position, the connecting portion having an opposing surface that can oppose and abut the mating connector in the rotation completion position, the opposing surface being configured so as to have an inclination in which a root portion of the other of the pair of arm plates is located at a position farther from the mating connector than a root portion of the one of the pair of arm plates. Effects of the invention According to the invention of claim 1, it is possible to improve the work efficiency of the fitting work of the connectors and to suppress the drawbacks associated with the fitting of the mating connector.
