Abstract

PURPOSE:To connect a pair of connectors with only a small force applied and extend the life by utilizing the lever action of a lever member to press a pair of connectors in the connecting direction to each other and providing protective measures of a coupling section for the lever member. CONSTITUTION:When a lever member 3 is rotated in the A direction at the time of connection of connectors, the lever member 3 serves to pull a female connector on the opposite side. At the final stage of rotation, a warp section 21 hits the locking projection 9 of a locking member 18, the warp section 21 rides on the inclined face 9a of the locking projection 9, the plate body section 8 is elastically deflected inward, the locking projection 9 enters a lock hole 7, and the lever member 3 is locked as it is. When this lock state is to be released, the locking member 18 is slid backward until it is hooked on a hooking projection 17b and the lever member is rotated, then the locking projection 9 can be easily released from a submerged section 20. Connectors can be easily connected with a relatively small force applied by utilizing a lever, and durability is improved.

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, in order to connect multi-polar connectors having a considerable number of connection terminals, methods such as tightening PO II/Lφ nuts have been generally adopted, and it is extremely troublesome to tighten or disconnect the connectors. 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.

[Problems to be Solved by the Invention] FIGS. 7 to 10 show a connector that realizes the above-mentioned desire and is a premise of the present invention, and FIG. 7 shows a pair of connectors separated, Figure 7 (a) is a plan view, (b)

) is a plan view, and (b) is a side view, in which 1 indicates a female connector and 2 indicates a male connector.0 These female connectors 1 and male connectors 2, which are made of synthetic resin, have a large number of Terminal accommodating holes (not shown) are provided, and connection terminals are accommodated in these terminal accommodating holes. and,
Lever members 3 made of a hard material such as metal are provided on both sides of the male connector 2 and have a < character shape when viewed from the side. It is approximately U-shaped, with approximately 4 mm diameter around the supporting shafts 4 on both sides.
It is supported so that it can rotate about 5 degrees. 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. 7, 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 with an edge bent inwardly 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. 9, the locking protrusion 9 has an inclined surface 9a on its upper half to facilitate fitting into the locking hole 7 of the lever member 3. It is designed to be difficult to remove.

On the other hand, on the female connector 1 side, there is a hooking shaft portion 1 hooked by the hooking portion 6 as an engaging portion cooperating with the lever member 3.
0, and a flange 11 for attaching the female connector l to a panel or the like. The male connector 2 is provided with an escape groove 12 into which the hooking shaft portion 10 enters.

When connecting the female connector l and the male connector 2, the seventh
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 IO, and the lever member 3 is By continuing to rotate, the female connector l is pulled towards the male connector 2 by the lever action of the lever member 3, and the

The force applied at this time is small, and eventually the plate portion 8 on which the locking protrusion 9 is provided is bent inward, and the locking protrusion 9 is fitted into the locking hole 7, as shown in FIG. It becomes a connected state, and the lever member 3
serves as a locking mechanism provided in a normal connector 1 to ensure the connection between the female connector 1 and the male connector 2. 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 flange 11 of the female connector 1 is pushed out by the back of the lever member 3 by rotating in the direction of arrow B shown in , the female connector 1 can be pushed out by the lever action and the female connector 1 and the male connector 2 can be separated. Can be done.

In addition, in this connector, if the lever member 3 is provided with a pressing part 13 that is bent inward in the same way as the hook part 6, as shown in FIG. The hooking shaft portion 10 can be pushed by the portion 13 to release the connection between the connectors 1.2.

However, in the above-mentioned connector, the locking protrusion 9 is integrally provided with the female connector 12 using a synthetic resin material, but if the lever member 3 is made of a hard material such as metal, the locking protrusion 9 and the locking protrusion 9 As I combined and removed them many times.

There is a high possibility that the locking protrusion 9 will be scraped off and become useless.

9 is formed. In use, as shown in FIG.
The locking member 18 is attached to the male connector 2 by being locked to the male connector 7a. Note that at this time, the lever member 3 has already been attached to the male connector 2;
) is a plan view in which illustration of the lever member 3 is omitted; (b)
is a side view. The lock hole 7 of the lever member 3 is formed to be slightly longer, and on one side of the lock hole 7 there is provided a sunken part 20 which is bulged into a chevron shape for the locking protrusion 9 to pass through.
A tongue-shaped warped portion 21 is provided which is lined up with and spread outward. In addition.

22 is a reinforcing rib.

When the connectors 1 and 2 are connected together, when the lever member 3 is rotated in the direction A, the lever member 3 acts to pull the mating female connector 1 (not shown).

When the lever member 3 reaches its final stage of rotation, the warped portion 21 hits the locking projection 9 of the locking member 18.The warped portion 21 rides on the inclined surface 9a of the locking projection 9, and the plate portion 8 is turned inside. The locking protrusion 9 is elastically bent as shown in FIG. 4(a),
As shown in (b), it can be inserted into the lock hole 7 and the lever member 3 can be locked as it is.

In order to release this locked state, Fig. 5(a),
As shown in (b), slide the locking protrusion 9 backward until it matches the recessed part 20, that is, until the locking member 18 is locked with the locking protrusion 17b, and then rotate the lever member in the direction B. By moving the locking protrusion 9, the locking protrusion 9 can be easily pulled out from the recessed portion 20. As described above, by further rotating the lever member 3, the female connector 1 can be pushed out.

The effects of this second embodiment are almost the same as those of the first embodiment, except that the force of the lever member 3 cannot be used when the connectors 1.2 are separated.

In this way, when the locking protrusion 9 is engaged with the locking hole 7, the lever member 3 can be inserted into the locking hole 7 by utilizing the deflection of the plate portion 8, and when the coupling is released, the lever member 3 can be inserted into the locking hole 7. Since the locking protrusion 9 can be removed from the recessed part 20, the locking protrusion 9 is almost never damaged by the lever member 3. Even if it is damaged, the locking member 18 can be replaced. This allows the connector to have a long service life.

In the above embodiment, the locking protrusion 9 may be provided on the lever member 3 and the locking hole 7 may be provided on the male connector 2, and the male connector 2 may also have an elongated hole 19 that is engaged with the locking member 18. Protrusions 17a and 17b may also be provided.

[Effect of the invention] As explained above, the connector according to the present invention is as follows.

A pair of connectors can be pressed in the direction of joining each other using the lever action of the lever member, so multi-pole connectors, which conventionally require a large amount of force to be joined by methods such as port/nut tightening, can be joined by simply applying a small force. This makes it possible to connect multi-pole connectors, etc., which used to be done using tools, easily and quickly, and also provides protection for the engagement part with the lever member. Therefore, life can be extended.
