Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector used for connecting a large number of electric wires.

[Prior Art] Conventionally, for example, relatively small connectors with about 10 pins or less do not require much force to be connected, so they can be pushed in manually by humans, but multi-pole connectors with about 20 pins or more When it comes to connectors, the frictional resistance between mating connection terminals increases, so a large amount of force is required for connection.

Therefore, in the past, methods such as port-and-nut tightening have generally been used to connect multi-pole connectors having a considerable number of connection terminals, and it is extremely troublesome to connect or disconnect them. In addition, as a special example, a multi-pole connector has been proposed in which the structure is devised so that it can be connected with a small force by using gears, etc., but this type of connector is not suitable for the structure of the connector. It has the disadvantage of being subject to certain restrictions.

[Object of the Invention] An object of the present invention is to enable connectors that normally require a large force to be connected, such as multi-pole connectors, to be easily connected by applying a relatively small force using a lever. Our goal is to provide connectors.

[Summary of the invention] The gist of the present invention is to achieve the above objects.

Of a pair of first and second connectors to be coupled, the first connector is provided with a lever member that is rotatable around a fulcrum, and the second connector is provided with a locking member that cooperates with the lever member. A connector characterized in that a mating portion is provided, and a force is applied to the engaging portion by a lever action caused by rotation of the lever member, thereby drawing the second connector toward the first connector side. It is.

[Embodiments of the invention] The present invention will be explained in detail based on illustrated embodiments.

J shows a separated state of a pair of connectors in the first embodiment of the present invention, FIG. 1(a) is a plan view, FIG. 1(b) is a side view, and FIG. 2 shows a coupled state. , (a) is a plan view, and (b) is a side view, where l indicates a female connector and 2 indicates a male connector. These female connectors l and male connectors 2, which are made of synthetic resin, include:
A large number of terminal accommodating holes (not shown) are provided, and connection terminals are accommodated in these terminal accommodating holes.

A lever member 3 made of a hard material such as a lever-shaped metal is provided on both sides of the male connector 2.
is connected at both ends thereof, and is formed into a substantially U-shape when viewed from above, and is supported so as to be able to rotate approximately 45 degrees around support shafts 4 on both sides. A spring (not shown) is attached to the support shaft 4, and the lever member 3 is biased to the rotational state shown in FIG. 1, but the rotation is stopped by the stopper 5. Further, a hook portion 6 whose edge is bent inward is provided near the support shaft 4 of the lever member 3, and a lock hole 7 is further provided in the intermediate portion of the lever member 3.

Plate portions 8 extend from both sides of the male connector 2, and the plate portions 8 are provided with locking protrusions 9 that fit into the lock holes 7. In addition.

As shown in FIG. 3, the upper half of the locking protrusion 9 has an inclined surface 9a so that it can be easily fitted into the lock hole 7 of the lever member 3, and once fitted, it is difficult to accidentally come off. It looks like this. Further, on the female connector 1 side, a hooking shaft portion 10 is provided as an engaging portion that cooperates with the lever member 3, and is hooked by the hooking portion 6, and furthermore, a flange 11 for attaching the female connector l to a panel or the like is provided. It is provided. And, the male connector 2 has a relief of 17g into which the hooking shaft portion 10 enters! 12 are provided.

When connecting the female connector 1 and the male connector 2, the first
After the male connector 2 is slightly fitted to the female connector 1 in the state shown in the figure, when the lever member 3 is rotated in the direction of arrow A, the hook part 6 is caught on the hook shaft part 10, and the lever member 3 is By continuing to rotate, the female connector 1 is drawn toward the male connector 2 by the lever action of the lever member 3,
Both connectors 1.2 are connected. The force used at this time is small, and at the final stage of rotation of the lever member 3, the plate portion 8 provided with the locking protrusion 9 is bent inward.

The locking protrusion 9 fits into the locking hole 7, resulting in a coupled state as shown in FIG. This will serve as a locking mechanism. In this state, the connection terminals in the single connector 1.2 are completely fitted together.

Next, when releasing the connection between the female connector l and the male connector 2, the plate part 8 is bent inward to remove the lock hole 7 from the lock protrusion 9, and then the lever member 3 is removed as shown in FIG. If the flange 11 of the female connector 1 is pushed out by the back of the lever member 3 after rotating in the direction of arrow B shown in FIG.
The female connector 1 is pushed out by the lever action, and the female connector 1
and the male connector 2 can be separated.

4 and 5 show a second embodiment, in which the lever member 3 is attached to the female connector 1, and the hook portion 6 is formed as a part of the hook portion 13 provided on the lever member 3. . Further, the male connector 2 is provided with an escape groove 14 into which the support shaft 4 of the lever member 3 enters when coupled.

In this case as well, if the lever member 3 is rotated in the A direction after the hooking shaft portion 10 is engaged with the hooking portion 6, the male connector 2 will be drawn toward the female connector 1.

In this embodiment, in order to separate the connectors 1 and 2, it is necessary to remove the locking protrusion 9 from the lock hole 7, but the lever action of the lever member 3 cannot be utilized.

In the third embodiment shown in FIGS. 6 and 7, the lever member 3 is attached to the flange 11 of the female connector 1 via a bearing 15 so as to be rotatable about the support shaft 4. The operation in this embodiment is almost the same as that in the second embodiment, but since the support shaft 4 is directly attached to the flange 11, there is an escape IJ 14 for the support shaft 4 to enter the male housing 2. There is no need to provide

Furthermore, in the fourth embodiment shown in FIGS. 8 and 9,
The lever members 3 are attached to the male connector 2, and the directions of rotation of the lever members 3 are different. That is, in the connected state, the lever member 3 is parallel to the flange 11 of the female connector 1, as shown in FIG.
The position of the locking protrusion 9 is also provided on the front side of the male connector 2, and the direction of the inclined surface 9a is also 90 degrees different from that of the previous embodiment. When connecting, the lever member 3 is rotated in the direction of arrow B to connect the connectors 1 and 2 together.

Furthermore, FIGS. 10 and 11 show a fifth embodiment, in which the lever member 3 has a bearing 15 above the flange 11 of the female connector l.
, is rotatably attached via a support shaft 4, and a lever member 3
The hooking shaft portion 10 of the male connector 2 is locked by the circular arc portion 16 provided in the holder 1, and the male connector 2 is pushed into the female connector 1. Further, the locking projection 9 is locked by the back of the lever member 3 without providing the lock hole 7 in the lever member 3.

In the embodiments described above, the hooking portion 6 and the hooking shaft portion 10 may have a reverse relationship, that is, the hooking shaft portion 10 may be provided on the lever member 3, and conversely, the hooking portion 6 may be provided on the female connector l or the male connector l. It may also be provided on the connector 2 side. Further, the locking protrusion 9 may be provided on the lever member 3, and conversely, the locking hole 7 may be provided on the male connector 2 or female connector 1.

[Effects of the Invention] As explained above, the connector according to the present invention can press a pair of connectors in the direction of joining each other using the lever action of the lever member. Multi-pole connectors that previously required a large amount of force can now be joined by only applying a small force, and the work of joining multi-pole connectors, etc. can be performed easily and quickly.
