Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a lever of a lever-type connector, and more particularly, to a lever-type connector that is coupled by using a lever attached to a first connector of a first connector and a second connector that are mated with each other. The lever can be easily rotated from the temporary locking position where the lever is stopped and held before the start.

[0002]

[Prior Art]

 Conventionally, when a male-female connector such as a 20-pole or more is mated with a male / female, a large coupling force is required. Therefore, it is possible to easily couple by applying a relatively small force using a lever that utilizes the lever principle. A lever type connector is provided.

In this type of lever connector, as shown in FIG. 5, a lever 2 is freely rotatable via a support shaft 3 on an outer surface of a first connector 1 of one female connector which is mated with each other. And a locking hole 4 is bored in the lever 2, while a locking pin 5 that is locked at the time of fitting in the locking hole 4 is projectingly provided on the second connector 6 composed of the other male connector. There is.

Before the connector is fitted, the lever 2 is prevented from rotating in the arrow X direction by a stopper 7 provided on the connector 1, and the inner surface of the lever 2 faces the outer surface of the first connector 1. A stopper (not shown) is provided on the surface for locking the protrusions and recesses to prevent rotation in the direction of the arrow Y (the direction in which the lever is rotated) for temporary locking.

In the lever-type connector, when mated, the second connector 6 is pushed into the opening 8 provided in the first connector 1 as shown by the arrow, and the locking pin 5 is provided on the outer wall of the first connector 1. The lever 2 is inserted through the insertion hole 9, and is inserted into the locking hole 4 through the recess 10 that is cut out on the inner surface of the lever 2. After the locking pin 5 is inserted into the locking hole 4 by the above-mentioned pushing, the lever 2 is rotated in the arrow Y direction to move the locking pin 5 according to the movement of the locking hole 4. The second connector 6 is pulled up to the bottom surface side of the opening 8 of the first connector 1 to be joined.

[0006]

[Problems to be solved by the device]

 In the above-mentioned conventional lever, as shown in the figure, the shape of the locking hole 4 is such that the tip 4a is opened horizontally in the inserting direction of the locking pin 5, and the guide portion 4b continuous from the tip 4a in the horizontal direction. The guide portion 4c is curved upward. In addition, an arcuate portion 4d into which the locking pin 5 is fitted is formed at a continuous point with the lower surface side of the guide portion 4c rising from the lower surface side of the horizontal guide portion 4b in a curved shape.

Since the locking hole 4 has the above-described shape, the pressed locking pin 5 fits into the arc portion 4d as shown in FIG. 6, and the lever 2 moves to the stopper as described above. Due to the provisionally locked state in which the protrusions and recesses are fitted together, it is not possible to smoothly perform the rotation operation after releasing the temporarily locked state of the lever 2, and there is a drawback that the operability is not good. That is, it is necessary to rotate the locking pin 5 while adjusting the angle of the lever so that the locking pin 5 comes out of the arc portion 4d of the locking hole 4, or to manually adjust the position of the locking pin 5. It is necessary to apply a force to rotate over the concave and convex fitting of the stopper.

The present invention is intended to solve the above-mentioned drawbacks, and the mutual relationship between the pushed locking pin and the locking hole is set so as not to make a positional relationship that makes it difficult to rotate the lever. By pushing the locking pin into the locking hole, the lever is released from the temporarily locked state and automatically rises in the direction of rotational operation to improve the operability of the lever.

[0009]

[Means for Solving the Problems]

 That is, according to the present invention, of the first connector and the second connector which are fitted to each other, the lever is rotatably supported on the first connector and the locking pin is projectingly provided on the second connector. A locking hole into which the locking pin is inserted at the time of fitting is provided in the lever, and the lever is rotated to move the locking hole to pull the second connector toward the first connector through the locking pin. In the mating lever type connector, the shape of the locking hole is set so that the lever is automatically raised in the rotational operation direction at the position where the locking pin is inserted into the tip of the locking hole. A characteristic lever-type connector is provided.

More specifically, in the shape of the locking hole, the tip opens in the horizontal direction, which is the inserting direction of the locking pin, and the upper and lower guide surfaces continuous with the opening end curve upward, When the locking pin inserted from above contacts the upper and lower guide surfaces, the curvature of the upper and lower guide surfaces is set so that the lever automatically rotates about the fulcrum in the rotation operation direction by the set angle. There is.

[0011]

[Action]

 By setting the shape of the locking hole provided on the lever as described above, when the connector is fitted, the connector with the locking pin is pushed into the connector with the lever and the locking pin is engaged. Simply inserting it into the stop hole, the lever will rotate in the direction of rotation by only a set angle, for example, 10 degrees, and the temporary locking of the stopper fitted in the concavo-convex will be released, and it will automatically rise. Therefore, the subsequent rotation operation can be easily performed.

[0012]

【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. Since the first and second connectors themselves for male and female fitting are the same as those of the connectors shown in FIGS. 5 and 6, the same components are designated by the same reference numerals and the description thereof will be omitted.

The first connector 1 made of a female connector and the second connector 6 made of a male connector are multi-pole connectors in which a large number of terminal accommodating chambers (not shown) are arranged in parallel, and as described above, the first connector is used. The second connector 6 is inserted into the inside of the first opening 8 from the edge thereof in the direction indicated by the arrow so that they are fitted to each other.

As shown in FIG. 2, the lever 11 attached to the first connector 1 is U-shaped and integrally molded from synthetic resin, and the left and right side portions 11a and 11b are connected to each other via the central connecting portion 11c. The shape. The left and right side portions 11a and 11b are arranged outside the left and right side surfaces of the first connector 1, respectively, and rotatably support the lever 11 to the first connector 1 via the support shaft 3.

As shown in FIGS. 1 and 3, the left and right side portions 11a, 11b of the lever 11 are formed with penetrating locking holes 12 having a generally upward arc shape. Specifically, the tip 12a opens in the horizontal direction, which is the insertion direction of the locking pin 5, and the upper and lower guide surfaces 12b and 12c continuous with the opening tip 12a are curved upward with a predetermined curvature. I am making it. When the locking pin 5 inserted from the opening tip 12a contacts the upper and lower guide surfaces 12b, 12c, the lever 11 rotates about the support shaft 3 as a center in the Y direction of the operation direction (10 in this embodiment). (Degrees) is set to rotate automatically

In other words, the locking hole 12 is formed with a horizontally oriented circular arc portion into which the pushed locking pin 5 is fitted, as shown in FIGS. 5 and 6 of the conventional example. However, the pushed locking pin 5 is immediately guided by the curved upper and lower guide surfaces 12b and 12c, and the locking hole 5 is forcibly rotated by the horizontally pushed locking pin 5. Is set.

In the lever-type connector having the above structure, when the connector is a single connector before the first connector 1 and the second connector 6 are fitted to each other, the lever 11 rotates in the operating direction with respect to the inner surface of the lever 11 and the first connector. The temporary locking portion (not shown) which is fitted between the outer surface and the outer surface of the first locking member prevents the rotation in the opposite direction by the stopper 7 to maintain the temporary locking state.

When connecting the first connector 1 and the second connector 6, as shown in FIG. 4A, the second connector 6 is pushed into the opening 8 of the first connector 1 from the opening end. The locking pin 5 of the second connector 6 is first inserted through the insertion hole 9 of the first connector 1, inserted into the recess 10 of the lever 11, and then pushed into the opening tip 12a of the locking hole 12.

Since the locking pin 5 is pushed into the locking hole 12 from the horizontal direction and the opening tip 12a is oriented in the horizontal direction, the locking pin 5 can be smoothly pushed into the opening tip 12a. I can. As soon as the locking pin 5 is pushed into the opening tip 12a, it comes into contact with the arc-shaped upper and lower guide surfaces 12b and 12c, and the locking pin 5 moves in the horizontal direction. , As shown in FIG. 4 (b), it rotates a predetermined angle (10 degrees) in the direction of arrow Y.

As described above, the pushing force of the locking pin 5 causes the lever 11 to automatically rise in the rotational operation direction by the set angle. At this time, the temporary locking stopper (not shown) between the inner surface of the lever 11 and the outer surface of the first connector 1 is unlocked, and the lever 11 rotates in the rotational operation direction.

As described above, when the second connector 6 is pushed into the first connector 1 for the first time, the lever 11 releases the temporary lock and automatically rises in the rotational operation direction. The rotation operation can be performed very easily, and the operability of the lever can be improved.

When the fitting of the first connector 1 and the second connector 6 is completed, the locking means (not shown) provided in these connectors are locked to firmly couple them in the fitted state.

[0023]

[Effect of the device]

 As is apparent from the above description, according to the present invention, the locking pin is inserted into the locking hole in the first step of pushing the one connector into the other connector by changing the shape of the locking hole formed in the lever. As a result, the lever is released from the temporarily locked state and automatically rises in the rotational operation direction, so that the operability of the lever can be made extremely excellent.

Further, the present invention has an extremely simple structure and requires only a slight improvement to the conventional product, so that the present invention can be implemented without increasing the cost and has great practical value.
