Japanese Patent No. 3643283 JP 2007-5088 A JP 2004-39342 A

<Problems of conventional devices>
In the invention described in Patent Document 1, the first connector has a lever and a slide member, and the second connector has a structure that cooperates with the lever. It was complicated. Moreover, in the actual insertion work, the connector is often inserted by holding only the electric wire. However, in the connector of Patent Document 1, the mechanism that cooperates with the lever does not work unless the slide member is always pressed. The insertion work was complicated.
Since the invention described in Patent Document 2 has a lever to be pressed when inserting the connector, it is necessary to press the lever in addition to the electric wire when inserting the connector. Met.
The invention described in Patent Document 3 does not have a lever to be pressed at the time of insertion, but requires a complicated cam groove and a large number of rotation fulcrums / pins / holes. The mechanism is complicated and the structure is easily damaged. It was.

<Object of the present invention>
The present invention was made to solve the above-mentioned drawbacks, and in actual connector insertion work, the connector is often inserted by holding the electric wire, but it is not necessary to press a lever or a slider other than the electric wire, And it aims at providing the connector with a built-in lever which does not require a complicated cam groove and many rotation fulcrum, pins, and holes.

The present invention has been made to solve the above problems, and the premise part of the lever built-in connector according to the first invention of the present application comprises a female housing and a male housing having a space for housing the female housing therein. A lever built-in connector, wherein the female housing includes a lever outside the housing, and the male housing presses the lever between the inside of the male housing and the outside of the female housing, and the lever by pressing the pressing member is that it and a pull boss drawn inside the lever.

According to a first aspect of the present invention, the lever includes a pair of L-shaped levers that are pivoted about a pin symmetrically, and a boss at a close distance is disposed at the tip of the L-shaped lever. In other words, a pull-in curved surface is formed to be pulled in .

  According to the first invention, a connector with a built-in lever that does not require pressing a lever or a slider in addition to the connector in an actual connector insertion work, and does not require a complicated cam groove or a large number of pivots, pins, or holes. Is obtained.

Furthermore, according to the first invention, the lever can reliably pull the boss of the male housing inward.

<Configuration of connector with built-in lever according to the present invention>
1 and 2, the lever built-in connector 10 according to the present invention includes only a female housing 20 and a male housing 30 described below.

<Female housing 20>
The female housing 20 contains a large number of connection terminals as in the conventional product, and is provided with a terminal window 2H for this purpose, which is the same as the conventional product.
The female housing 20 according to the present invention is different from the conventional product in that a lever 2L for moving the retracting boss 3B provided on the inner side of the male housing 30 is formed as follows and provided on the outer side of the housing. Is a point.

<< Lever 2L >>
The lever 2L is provided with a pair of L-shaped levers 2L1 and 2L2 that rotate about a pin 2P symmetrically. Retractable curved surfaces 2S1 and 2S2 are formed at the tips of the L-shaped levers 2L1 and 2L2, respectively, and these retracted curved surfaces 2S1 and 2S2 draw the boss 3B that is at a close distance by retracting the retracted curved surfaces 2S1 and 2S2 from each other. 2S1 and 2S2 are arranged at the positions where the curved surfaces are drawn inside and the positions where they become. Since the pair of L-shaped levers 2L1 and 2L2 are in a separated state at the time of provisional fitting, the lead-in curved surfaces 2S1 and 2S2 are also separated from each other.

<Male housing 30>
The male housing 30 is the same as the conventional product in that it has a space for housing the female housing 20 therein. The male housing 30 is different from the conventional product in that a slight gap is provided between the inside of the male housing 30 and the female housing 20, and the lever pressing members 3P1, 3P2 and the lever pressing members 3P1, 3P2 described below are provided in the gap. The retracting boss 3B is provided in the middle.

<< Lever pressing member 3P1, 3P2 >>
In a state where the female housing 20 and the male housing 30 are temporarily fitted (see FIG. 3 (1)), the lever pressing members 3P1 and 3P2 are in light contact with the vicinity of the end portions of the L-shaped levers 2L1 and 2L2 of the female housing 20. Is provided.
When the female housing 20 is pushed into the male housing 30 for fitting, the lever pressing members 3P1 and 3P2 of the male housing 30 push the L-shaped levers 2L1 and 2L2 of the female housing 20 to bring the L-shaped levers 2L1 and 2L2 closer to each other. As a result, the same actions and effects as if the L-shaped levers 2L1 and 2L2 were grasped by hand are obtained.

<< Retraction Boss 3B >>
In a state where the female housing 20 and the male housing 30 are temporarily fitted, the lever pressing members 3P1, 3P2 are in light contact with the vicinity of the end portions of the L-shaped levers 2L1, 2L2 of the female housing 20, and the drawing curved surface 2S1, The tips of 2S2 are still open. The pull-in boss 3B is provided at a position where the pull-in curved surface 2S1 and 2S2 are pulled into the lever side when they come into contact with each other.

<Operation of the connector with a built-in lever according to the present invention>
The connector fitting operation using the female housing 20 and the male housing 30 will be described with reference to FIG. FIGS. 3A and 3B are plan sectional views for explaining the connector fitting operation using the female housing 20 and the male housing 30. (1) is a temporary fitting, (3) is a fitting completion, and (2) is in the middle. FIG.
(1) The female housing 20 is inserted into the male housing 30 and temporarily fitted.
FIG. 3 (1) shows this temporarily fitted state. In this temporarily fitted state, the lever pressing members 3P1, 3P2 are in a state of lightly contacting the vicinity of the end portions of the L-shaped levers 2L1, 2L2 of the female housing 20, and the leading ends of the retracted curved surfaces 2S1, 2S2 are also open. The drawing boss 3B is not yet captured by these drawing curved surfaces 2S1 and 2S2.
(2) When the female housing 20 is further pushed, the L-shaped levers 2L1, 2L2 of the female housing 20 are pressed by the lever pressing members 3P1, 3P2 of the male housing 30, and the distance between the L-shaped levers 2L1, 2L2 is reduced. Therefore, the drawing curved surfaces 2S1 and 2S2 on the opposite side of the pin 2P draw the drawing boss 3B inward. FIG. 3 (2) shows this state.
(3) When the female housing 20 is further pushed, the L-shaped levers 2L1, 2L2 of the female housing 20 are finally pressed by the lever pressing members 3P1, 3P2 of the male housing 30, and the distance between the L-shaped levers 2L1, 2L2 Therefore, the pull-in curved surfaces 2S1 and 2S2 complete the pull-in of the pull-in boss 3B and the fitting is completed.

<Effect of the lever built-in connector according to the present invention>
According to the lever built-in connector according to the present invention, when the female housing 20 is pushed in the fitting direction, the lever pressing members 3P1 and 3P2 in the male housing 30 push the L-shaped levers 2L1 and 2L2 of the female housing 20, thereby The force effect works and the insertion force is reduced. Further, since the L-shaped levers 2L1 and 2L2 are also pushed simply by pushing the female housing 20 in the fitting direction, it is not necessary to push the lever separately, and the boosting effect by the lever acts only by the normal connector fitting operation. become.
In actual connector insertion work, the connector is often inserted by holding the electric wire. However, according to the present invention, it is not necessary to press any lever or slider in addition to the connector, and there are complicated cam grooves and many Since no rotation fulcrum, pin, or hole is required, manufacturing is simplified and it is difficult to break.
