Abstract

PROBLEM TO BE SOLVED: To fit a lever to a side retainer type connector without increasing a size. SOLUTION: A female connector housing 20 is a horizontally flat rectangular parallelopiped, and the upper surface thereof is formed to be suitable for fitting a retainer 40. This retainer 40 slightly projects from the upper surface of the housing 20 at a temporary engagement position, but a relief part 41 is recessed so as to partly cut a part of the projected part. As a result, even when the lever 30 is fitted along a direction for clamping both upper lower sides of the female connector housing 20, the lower end of the lever 30 is housed in the relief part 41, thereby avoiding interference between the lever 30 and the retainer 40. According to this construction, the lever 30 can be fitted in a direction along the length of the female connector housing 20, thereby avoiding an increase in the size of the whole of a connector.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever-type connector provided with a retainer.

[0002]

2. Description of the Related Art As shown in FIG.
There is a configuration including a retainer 1 for secondary locking of a plurality of terminal fittings (not shown) assembled in a primary locking state at a time. The retainer 1 is formed in a lattice shape, and the connector housing 2 is formed in a horizontally long rectangular parallelepiped shape.
To be fitted on the upper surface of the. The retainer 1 is held at a temporary locking position (position shown in FIG. 6) slightly protruding from the upper surface of the connector housing 2 when the terminal fitting is assembled into the cavity 3. After assembling the terminal fitting, the upper surface of the retainer 1 is pushed in, so that the terminal fitting is secondarily locked.

By the way, there is a case where it is desired to attach a gate-shaped lever to the female connector (hereinafter referred to as a side retainer type connector) having the above-mentioned structure, and to operate the lever smoothly to connect the lever. . However, in the side retainer type connector, since the retainer slightly projects from the upper surface at the temporary locking position, the lever is attached in a direction to sandwich the upper and lower sides (both sides including the long side in the mating surface with the mating connector). Then, the lever interferes with the retainer at the temporary locking position.

On the other hand, in order to avoid interference with the retainer, the lever is attached in such a manner that the left and right sides (both sides including the shorter side of the mating surface with the mating connector) are sandwiched while avoiding the side surface to which the retainer is attached. Although it is conceivable, the length of the lever is required to be a certain length in relation to the coupling force, so if the lever is mounted in a direction sandwiching the left and right sides, the lever will protrude greatly from the connector housing, The connector will be enlarged as a whole.

In short, a lever cannot be attached to a side retainer type connector in which a retainer is attached to a surface including a long side of a mating surface with a mating connector unless the size is increased. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a miniaturized side retainer type lever-type connector.

[0006]

In order to achieve the above object, a lever type connector according to the present invention has a connector housing having a flat box-shaped portion having different vertical and horizontal dimensions as viewed from a mating surface with a mating connector housing. And a lever that is mounted with the connector housing sandwiched therebetween, and a side of the outer side surface of the connector housing that includes the long side of the mating surface is located at a position slightly protruding from the side surface at the temporary locking position. A lever-type connector to which a retainer to be held is attached and which displaces both connector housings to a coupling position by a rotation operation of a lever, wherein the lever is oriented so as to sandwich a side surface on which the retainer is attached and a side surface opposed to the side surface. At the same time, the retainer is recessed in the retainer to avoid interference with the lever at the temporary locking position. Characterized in that they are made.

[0007]

According to the present invention, since the escape portion is formed in the retainer in a recessed manner, even if the lever is mounted so that the side where the retainer is mounted and the side opposite to the side are sandwiched, the provisional engagement is possible. At the stop position, the retainer does not interfere with the lever. Therefore, although the connector is a side retainer type connector, the lever can be mounted in a direction sandwiching both side surfaces including the long side in the mating surface with the mating connector housing, thereby avoiding an increase in the size of the connector. It can be a lever type connector.
