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] Conventional 1: Relatively small connectors of, for example, 10 pins or less, do not require much force to connect and disconnect, so they can be pushed in by hand.
When it comes to multi-pole connectors with approximately 0 or more poles, the frictional resistance between mated connection terminals becomes large, so a large force is required for coupling and disassembly.

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.

[Objective of the Invention] An object of the present invention is to provide a method for easily connecting connectors such as multi-pole connectors, which normally require a large force for connection, by applying a relatively small force using a lever. Our goal is to provide you with a new connector.

[Summary of the Invention] The gist of the present invention for achieving the above-mentioned object is that, of a pair of first and second connectors to be coupled, the first connector has a lever that is rotatable about a fulcrum. a member, the second connector is provided with an engaging part that cooperates with the lever member, and a force is applied to the engaging part by a lever action caused by rotation of the lever member to close the second connector. The lever member is pulled toward the first connector side, and by rotating the lever member in the opposite direction, the lever member comes into contact with a part of the second connector and pushes back the second connector. It is a connector.

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

FIG. 1 shows a separated state of a pair of connectors in a first embodiment of the present invention, and FIG. 1(a) is a plan view;
b) is a side view, FIG. 2 shows the combined state, and (
a) is a plan view, and (b) is a side view, where l indicates a female connector and 2 indicates a male connector.0 These female connectors l and male connectors 2 made of synthetic resin have a large number of connectors. Terminal accommodating holes (not shown) are provided, and connection terminals are accommodated in these terminal accommodating holes. Lever members 3 made of a hard material such as metal are provided on both sides of the male connector 2 and have a shape of "〈" when viewed from the side.
This lever member 3 is connected at both ends thereof, has a substantially U-shape when viewed from above, and is supported so as to be rotatable about 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 prevented by the stoppers 5 provided on both sides of the male connector 2. It's stopped. 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. A plate body part 8 extends from both sides of the male connector 2, and this plate body part 8
is provided with a locking protrusion 9 that fits into the locking hole 7. As shown in FIG. 3, the upper half of the locking protrusion 9 has a sloped surface 9a to facilitate fitting into the locking hole 7 of the lever member 3. It is difficult to remove at times. On the other hand, on the female connector L side,
A hooking shaft portion lO hooked by the hooking portion 6 is provided as an engaging portion that cooperates with the lever member 3, and a flange 11 for attaching the female connector 1 to a panel or the like is further provided. The male connector 2 has a hooking shaft part 1.
An escape groove 12 into which 0 enters is provided.

When connecting the female connector l 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 lO, and the lever member 3 is By continuing to rotate, the female connector 1 is drawn towards the male connector 2 by the lever action of the lever member 3,
Both connectors 1.2 are connected. The force applied at this time is small, and eventually the plate portion 8 on which the locking protrusion 9 is provided bends inward, and the rowing protrusion 9 fits into the locking hole 7, as shown in Fig. 2. The connected state is as shown, and the lever member 3
In order to secure the connection between the female connector 1 and the male connector 2, it plays the role of a locking mechanism provided in a normal connector. In this state, the connection terminals in both connectors 1 and 2 are completely fitted together.

Next, when releasing the connection between the female connector 1 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 female connector 1 is rotated in the direction of the arrow B shown in the figure and the two flange 11 of the female connector 1 are pushed out by the back of the lever member 3, the female connector 1 is pushed back by the lever action and the female connector 1 and the male connector 2 are separated. can do.

In addition, in this embodiment, as shown in FIG.
3, even if the flange 11 is not present, the pressing portion 13 can push the hooking shaft portion 10 to release the connection between the connectors 1.2.

In the above embodiment, the locking protrusion 9 is made of a synthetic resin material and is integrally provided with the male connector 2, but if the lever member 3 is made of a hard material such as metal, the locking hole 7 and the locking protrusion 9 are As the locking projections 9 are repeatedly connected and disconnected, there is a high possibility that the locking protrusions 9 will be scraped off and become useless.

FIGS. 5(a) and 5(b) are a plan view and a side view of a male connector 2 according to a second embodiment in which such countermeasures have been taken.
The locking protrusions 17a and 17b are arranged in parallel in the axial direction. Figures 6(a), (b), and (c) show the locking protrusion 9.
A plan view, a side view, and a front view of a frame-shaped locking member 18 for attaching to the male connector 2 are shown. A total of four long holes 19 are formed, two on the top and two on the top, for attaching the member 18 to the locking protrusions 17a, 17b of the male connector 2.

In use, as shown in FIG.
7a and attach the locking member 18 to the male connector 2. At this time, the lever member 3 is already attached to the male connector 2.
7(a) is a plan view in which the lever member 3 is not shown, and FIG. 7(b) is a side view.

The lock hole 7 of the lever member 3 is formed slightly long, and on one side thereof is provided with a sunken part 20 bulging into a chevron shape through which the locking protrusion 9 passes, and extends outward in line with the sunken part 20. A tongue-shaped warped portion 21 is provided.

Note that 22 is a reinforcing rib.

When connecting the connectors 1 and 2, when the lever member 3 is rotated in the inward direction, the hook portion 6 of the lever member 3 acts to pull the mating female connector 1 (not shown). Lever member 3
When the rotation reaches the final stage, the warped portion 21 engages the locking member 18.
The zero curvature portion 21 that abuts against the locking protrusion 9 rides on the inclined surface 9a of the locking protrusion 9, the plate portion 8 is elastically bent inward, and the locking protrusion 9 is bent as shown in FIGS. 8(a) and 8(b). ), insert the lever member 3 into the lock hole 7 as shown in
can be locked.

In order to release this locked state, Fig. 9(a),
As shown in (b), insert the locking protrusion 9 into the recessed part.

20, that is, the locking member 18 is placed in the locking protrusion 1
The locking protrusion 9 can be easily extracted from the recessed portion 20 by sliding it backward until it is locked in the locking portion 7b and then rotating the lever member in the direction B. As in the first embodiment, the female connector 1 can be pushed out by further rotating the lever member.

In this way, in this second embodiment, when the locking protrusion 9 is engaged with the lock hole 7, the lever member 3 can be inserted into the lock hole 7 by utilizing the deflection of the plate portion 8. Furthermore, since the locking protrusion 9 can be removed from the recessed part 20 when the connection is released, the locking protrusion 9 is almost never damaged by the lever member 3, and even if it is damaged, the locking protrusion 9 is not damaged. Since it is only necessary to replace the stopper member 18, the life of the connector can be maintained for a long time.

In the embodiment 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 bias. In some cases, it may be provided. 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 is capable of applying force in the direction of coupling and disassociating a pair of connectors with each other by utilizing the lever action of the lever member. Multi-pole connectors that require a large amount of force to be joined and separated by methods such as tightening can now be joined and separated just by applying a small force, making the work of joining and separating multi-pole connectors easier and faster. can be done.
