The upper casing member 11t is formed with a receiving hole 11tH1 to which the rotation shaft portion 122 of the rotation knob member 12 is rotatably attached.
On the lower end side of the receiving hole 11tH1, a bottom plate member 11tS having a fan-like shape and a through-hole for introducing a lead wire is formed at the center, and the rotating shaft portion 122 of the rotating knob member 12 is placed on the bottom plate member 11tS. . The portion without the bottom plate member 11tS passes through the upper casing member 11t, and the convex portion 123 of the rotary knob member 12 is disposed in this through portion.
With this configuration, the rotary knob member 12 is rotatably arranged on the upper casing member 11t, and the movement range of the convex portion 123 of the rotary knob member 12 (that is, the rotation angle of the rotary knob member 12) is the bottom plate. It is regulated according to the fan-shaped angle of the member 11tS.
The hole 11tH2 is a hole through which a screw (not shown) for assembling the upper casing member 11t and the lower casing member 11b is inserted. Note that the structure for assembling the upper casing member 11t and the lower casing member 11b is not limited to screwing, and may be appropriately selected from various engagement methods (for example, a structure such as a snap fit).

5A and 5B are diagrams showing the terminal member 13, in which FIG. 5A is a perspective view, FIG. 5B is a side view, FIG. 5C is a top view, and FIG. 5D is a front view. .

The terminal member 13 includes a bent portion 131 that is bent inwardly toward the other side surface portion 13S2 in one side surface portion 13S1 having a substantially U shape. A gap portion 132 is formed between the bent portion 131 and the side surface portion 13S2. The terminal member 13 is electrically connected to the conductive wire by inserting the conductive wire into the gap portion 132.
The bent portion 131 is formed to such a degree that it is in contact with the side surface portion 13S2 or has a slight gap (at least less than the thickness of the conducting wire) in a state where no force is applied to the terminal member 13. That is, the gap portion 132 is normally closed, and when the opening force is applied so that the U-shape of the terminal member 13 is changed to a V-shape, the gap portion 132 is also opened.
The substantially U-shaped side surface portion 13S2 is formed longer than the side surface portion 13S1 in which the bent portion 131 is formed, and the convex portion 123 of the rotary knob member 12 abuts on this portion, and the rotation knob member 12 rotates. When the side surface portion 13S2 is pushed open by the convex portion 123 during the movement, the gap portion 132 is also opened.

The rib 11bC is formed so as to fit inside the U-shape of the terminal member 13 that is substantially U-shaped, and is cut out at a portion located below the gap portion 132 of the terminal member 13 Have The notch shape is for reducing interference with the conductive wire sandwiched between the gap portions 132.
The lower casing member 11b is provided with a wiring structure continuing from the terminal member 13, an external connection terminal, and the like, but illustration and description thereof are omitted for the sake of simplicity.

FIG. 7 is a diagram for explaining the connection of the conductive wire W in the connection terminal device 1. From the viewpoint of visibility, the casing 11 is omitted.
As shown in FIG. 7, the convex portion 123 of the rotary knob member 12 is disposed so as to abut on the inner side of the side surface portion 13S2 of the terminal member 13, The part 13S2 is configured to be pushed open by the convex part 123. Therefore, when the turning knob member 12 is turned, the gap portion 132 of the terminal member 13 is opened, and when the turning knob member 12 is released, the gap portion 132 is closed by the elastic force of the terminal member 13 to be locked.
Further, the conducting wire insertion hole 12H is arranged so as to be substantially in line with the gap portion 132 of the terminal member 13, and the conducting wire W is inserted between the gap portions 132 by inserting the conducting wire W through the conducting wire insertion hole 12H. It has a configuration that can.
The connecting operation of the conducting wire W in the connection terminal device 1 having the above-described configuration is performed by inserting the conducting wire W into the conducting wire insertion hole 12H while turning the turning knob member 12 and passing the conducting wire W between the gaps 132 to turn the turning knob member 12. (This leads to the lead wire W being sandwiched between the gap portions 132).

As described above, according to the connection terminal device 1 of the present embodiment, a tool such as a screwdriver is not required, and the conductors can be connected by a very simple and easy operation.
Further, according to the connection terminal device 1 of the present embodiment, since the direction of attaching and detaching the conductive wire is on the rotation axis of the knob (rotating knob member 12), space saving of the terminal wiring portion of the device mounting this structure is achieved. Can be achieved.
In addition, a conductive wire insertion hole 12H for inserting a conductive wire into the rotary knob member 12 is formed. Recalling the tightening operation of a screw for turning the knob, the locking method is easy to understand, and a hole for wiring (conductive wire insertion hole) 12H) is at the knob, so the wiring location is clear and easy to understand. Therefore, it is possible to understand the operation method intuitively or immediately.
In addition, since the conducting wire insertion hole 12H through which the conducting wire is inserted is formed in the rotating knob member 12, a member for opening between the terminals sandwiching the conducting wire and a member for introducing the conducting wire are used as the turning knob. Since it is constituted by one member, the number of parts can be reduced and the configuration can be simplified, the device can be formed at low cost, and the device can be downsized.
Further, since the conductive wire is inserted into the rotary knob member 12, even when a plurality of connection terminals using a high voltage are provided adjacent to each other, the rotary knob member 12 can take an insulation distance. And the pitch between the terminals can be narrowed (the arrangement efficiency can be increased).

According to the connection terminal device 1 of the present embodiment, the conducting wire insertion hole 12H of the rotary knob member 12 is formed in a tapered shape, and the diameter of the insertion side of the conducting wire is increased, so that the workability of inserting the conducting wire is excellent. When the conducting wire is a stranded wire, the stranded wire may be scattered and the workability of insertion into the hole may be reduced, but this is reduced. In addition, since the stranded wires are connected in a disconnected state, it is possible to prevent the disconnected wires from touching an adjacent terminal or the like and causing a short circuit.
In addition, you may make it form a helical groove | channel or a rib inside the conducting wire penetration hole 12H. Thereby, the conducting wire of a strand wire can be made easier to put.

FIG. 8 shows another example of the rotating knob member. FIG. 8A is a perspective view, and FIG. 8B is a top view.
The rotating knob member 12 'shown in FIG. 8 is the same as the rotating knob member 12 of the embodiment except that a notch 125 is formed.
Since the turning knob member 12 ′ is formed with the notch 125, the conducting wire can be taken in and out of the conducting wire insertion hole 12 H ′ from the notch 125. Thereby, the rotation knob member 12 ′ can be detached from the connection terminal device 1 after the conductor is connected. By removing the rotary knob member 12 ′ after wiring, for example, it is possible to prevent the rotary knob member from rotating due to an object hitting the knob, releasing the lock, and disconnecting the conductor. Further, by removing the rotary knob member 12 ', the appearance is simplified and the design is excellent, and the apparatus is reduced in height.
In addition, although the rotation knob member 12 of embodiment is also a structure which can be attached or detached with respect to the connection terminal device 1, since it does not have the notch part 125, it seems that the other end side of conducting wire has already been connected to other apparatuses. In such a case, the rotary knob member 12 cannot be removed after wiring. Therefore, it is good also as a structure which attaches the rotation knob member 12 with respect to the connection terminal device 1 so that attachment or detachment is impossible.

9 and 10 show another example of the connection terminal device. The connection terminal device shown in FIGS. 9 and 10 is an example in which the rotary knob member is provided so as to be buried in the casing.
In the connection terminal device 1 ′ of FIG. 9, the upper casing member 11t ′ is formed with a recess 11t′R in which the rotary knob member 12 is buried and its upper surface is substantially the same as the upper surface of the upper casing member 11t ′. ing. As a result, the apparatus can have a flat structure with less unevenness, and it is possible to reduce the situation where the knob hits an object, the rotating knob member rotates, the lock is released, and the lead wire comes off. .
Although FIG. 10 is a simplified description, the rotary knob member 12 ″ is formed in a substantially cylindrical shape, and a knob rib is formed on the upper surface side thereof. In this example, the entire casing is buried. Similarly to the connection terminal device 1 ′ in FIG. 9, the device can have a flat structure with less unevenness, and it is possible to further reduce the disconnection of the conducting wire.

In the embodiment, the gap 132 of the terminal member 13 is normally closed, and is opened by the rotation of the rotation knob member 12 (the rotation of the rotation knob member causes the terminal member However, the present invention is not limited to this, and the gap 132 of the terminal member 13 is normally open, and the rotation knob member 12 This may be closed (by closing the gap against the elastic force of the terminal member by turning the turning knob member). In the latter case, the gap portion 132 is closed against the elastic force of the gap portion 132. Therefore, it is preferable to provide a mechanism in which the rotary knob member 12 is locked at the lock position.
