[Problems to be solved by the device]

However, this quick-connect terminal device has a drawback that it cannot be stored in a space having a low height because the height H is high as shown in FIG. The reason why the height becomes higher is that the dimension Y of the entire quick-connect terminal in the pressing direction of the locking spring 50 is X <Y as compared with the width dimension X perpendicular to the pressing direction. This is because it is necessary to secure the thicknesses t ₁ and t ₂ of the release button 53 that can withstand the bending load applied at the time of release. Note that a space is also required above the release button 53 to release the release button 53.

When disconnecting the wires, it is necessary to press the center position a of the release button 53 with the driver 60 or the like as shown in FIG. 12 in order to release all the poles at the same time. Since it is easy to push the ends b and c of 53, and in this case the electric wire cannot be detached, the central position a is pressed again, so that the release operation cannot be performed at once. Such an example is likely to occur when releasing the VVF electric wire, for example.

Therefore, an object of the present invention is to provide a quick-connect terminal device which can reduce the height and can surely remove a plurality of electric wires at one time without being restricted to a pushing position.

[0006]

[Means for Solving the Problems]

 The quick-connect terminal device of the present invention has a locking spring for locking the electric wire and a releasing piece at one side thereof so that the electric wire insertion direction is parallel and the pressing direction of the locking spring is the same direction. A plurality of quick-connect terminals arranged in the pressing direction, and a release button having a plurality of engaging portions arranged in the press direction, the engaging portions being provided over the quick-connect terminals and engaging with each of the release pieces. , A release button hole for accommodating each of the quick-connect terminals and having a plurality of wire insertion holes for inserting an electric wire into the quick-connect terminal formed on one side surface and further for slidably inserting the release button therein. And a case formed on one side surface of the wire insertion holes in the direction of arrangement.

[0007]

[Action]

 According to the configuration of this invention, when the electric wire is inserted through the electric wire insertion hole, the electric wire is locked by the locking spring. When the release button is pushed, the release piece engaged with the engaging portion is pushed, so that the locking spring is elastically deformed and the electric wire can be pulled out. In this case, the multiple quick-connect terminals are arranged in the pressing direction so that the wire insertion direction is parallel and the pressing directions of the locking springs are in the same direction, and the release button that spans the multiple quick-connect terminals has the locking spring side. Since the plurality of engaging parts that engage with the release pieces of the part are arranged side by side in the pressing direction, the pressing direction of the quick-connect terminal and the release button can be located in the line direction of the wire insertion direction, so the height is small. Therefore, the whole can be made thin or thin. Moreover, since the release pieces are arranged in the pressing direction of the locking spring, operating the release button across the quick-connect terminals in the pressing direction does not limit the release position of the release button. The lock spring can be reliably released at the same time.

[0008]

Embodiment An embodiment of the present invention will be described with reference to FIGS. That is, this quick connection terminal device has a quick connection terminal 1, a release button 2, and a case 3. The plurality of quick-connect terminals 1 have a locking spring 4 for locking the electric wire 5 and a release piece 6 on one side thereof so that the wire insertion direction A is parallel and the pressing direction B of the locking spring 4 is the same. Are aligned in the pressing direction. As shown in FIG. 4, in the quick-connect terminal 1 of the embodiment, both sides of a flat plate 11 are bent in the same direction to form a conductive piece 12 and a facing piece 13, and one end of the facing piece 13 is placed on the conductive piece 12 side. It is bent to form a locking spring 4, and a release piece 6 is integrally formed on one side thereof. Reference numeral 14 denotes an electric wire locking portion of the locking spring 4, which has a V-shaped groove.

The release button 2 has a plurality of engaging portions 7 arranged over the quick-connect terminals 1 and engaged with each of the release pieces 6 in the pressing direction B. As shown in FIG. 4, the release button 2 of the embodiment is formed in the shape of a rod having a rectangular cross section, the engaging portion 7 is recessed in the side surface thereof, and a recess for escaping the partition wall 16 of the case 3 between the engaging portions 7. 15 and a driver groove 19 is formed on the operation surface at the end.

The case 3 has a storage portion 8 for storing the quick-connect terminals 1, each of which has a plurality of wire insertion holes 9 for inserting the wires 5 into the quick-connect terminals 1 on one side thereof, and further has a release button 2. A release button hole 10 that is slidably inserted is formed on one side surface of the wire insertion hole 9 in the direction of arrangement. The case 3 of the embodiment is composed of a body 17 and a cover 18, which are joined by a known joining means (not shown), and a release button hole 10 is formed at the opening edge of the body 17 and the cover 18.

According to this embodiment, when the electric wire 5 is inserted through the electric wire insertion hole 9, the electric wire 5 is locked by the locking spring 4. When the release button 2 is pushed, the release piece 6 engaged with the engaging portion 7 is pushed, so that the locking spring 4 is elastically deformed and the electric wire 5 can be pulled out. In this case, the plurality of quick-connect terminals 1 are arranged in the pressing direction B so that the wire insertion direction A is parallel and the pressing direction B of the locking spring 4 is the same direction, and the release button 2 straddling the plurality of quick-connect terminals 1 is arranged. Since the plurality of engaging portions 7 that engage with the release pieces 6 on the side portions of the locking spring 4 are formed side by side in the pressing direction B, the pressing direction B of the quick-connect terminal 1 and the release button 2 are inserted into the wire. Since they can be located in the arrangement direction of the direction A, the height can be made small, so that the whole can be made thin or thin.

That is, assuming that the width dimension X and the height dimension Y of the locking spring 4 are X <Y, the overall height H'is Y-X minutes as compared with the height H of the conventional example. Just lower. Further, the thickness t can be made smaller than the thickness t _{1 of the} conventional example because most of the applied load is a compressive load. In addition, no space is required above the top surface of the case 3, and if there is a space in the direction of the release button hole 10 and the wire insertion hole 9 as shown in FIG. It can be inserted and the release button 2 can be operated by the driver 20 or the like. Reference numeral 21 is a mounting plate, and 22 is an obstacle. As shown in FIG. 7, it is possible to use the quick-connect terminal device in a vertical position and use it in a thin shape.

Moreover, since the releasing pieces 6 are arranged in the pressing direction B of the locking spring 4, by operating the releasing button 2 straddling the quick-connect terminal 1 in the pressing direction B, the pushing position of the releasing button 2 is restricted. Without being touched, the plurality of locking springs 4 can be reliably released simultaneously by one operation. That is, as shown in FIG. 1, no matter which position of the center position a and both end positions b 1 and c 2 of the operation surface of the release button 2 is pressed, the release pieces 6 are arranged in the moving direction of the release button 2, so that the respective release pieces 6 6 can be pushed smoothly. Further, since the releasing pieces 6 of the lock spring 4 contact the releasing button 2 at substantially the same positions, the releasing conditions are almost the same.

[Effect of the device]

 According to the quick-connect terminal device of this invention, when the electric wire is inserted through the electric wire insertion hole, the electric wire is locked by the locking spring. When the release button is pushed, the release piece engaged with the engaging portion is pushed, so that the locking spring is elastically deformed and the electric wire can be pulled out. In this case, arrange multiple quick-connect terminals in the pressing direction so that the wire insertion directions are parallel and the pressing directions of the lock springs are the same direction, and the release button that spans multiple quick-connect terminals has the lock spring side. Since a plurality of engaging parts that engage with the release pieces of the part are arranged side by side in the pressing direction, the pressing direction of the quick-connect terminal and the release button can be positioned in the line direction of the wire insertion direction. Therefore, the overall size can be made thin or thin. Moreover, since the release pieces are arranged in the pressing direction of the locking spring, by operating the release button that straddles the quick-connect terminals in the pressing direction, the pressing position of the release button is not limited, and multiple chains can be operated with one operation. There is an effect that the lock springs can be reliably released at the same time.
