[Problems to be solved by the device]

 By the way, when mounting the terminal block 20 as described above on a printed circuit board built in an electric / control device, a space for attaching the electric wire to the terminal member 23 is provided between adjacent parts. It is necessary to remember to leave this space in the design, but it may be difficult to install the wire, or the wire cannot be installed, and the printed circuit board must be redesigned. It was

Therefore, an object of the present invention is to provide a terminal block which can surely obtain a space required for attaching an electric wire to the terminal block and prevent a design mistake due to carelessness.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a terminal block including an insulating base and a terminal member provided in a compartment formed in the base, and an electric wire being connected to the terminal member. A projecting part that projects forward under the compartment, and projects to a position where the projecting part forms a space above the projecting part that is wide enough to connect an electric wire to the terminal member. The present invention provides a terminal block characterized in that

[0006]

[Action]

 Since the space for connecting the electric wire to the terminal member is automatically secured by the protruding portion, inadvertent design mistake can be prevented.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of an embodiment of a terminal block according to the present invention. FIG. 1 (A) is a perspective view with a side surface broken, and FIG. 1 (B) is a side view. The terminal base 1 of this embodiment includes a base 2 and a terminal member 3 attached to the base 2.

The base 2 made of synthetic resin or the like has a plurality of compartments 4 arranged adjacent to each other in the lengthwise direction of the base 2 for attaching the terminal member 3, and the compartments 4 above the compartment 4 are the same. A plurality of compartments 5 are formed adjacent to each other in the longitudinal direction of the base 2. The terminal pedestal 6 formed on the base 2, the partition 7 formed so as to stand upright from the terminal pedestal 6, and the terminal pedestal 6 and the vertical wall 8 orthogonal to the partition 7 are the bottom surface, the side surface of the compartment 4, And the rear surface. Further, the terminal pedestal 9 formed on the base 2, the partition 10 formed so as to stand upright from the terminal pedestal 9, and the terminal pedestal 9 and the vertical wall 11 orthogonal to the partition 10 are the bottom surface of the compartment 5, respectively. The side surface and the rear surface are formed.

The base 2 has a protruding portion 12 that is integrally formed with the base 2 and protrudes forward under the compartment 4. The protruding portion 12 has a substantially rectangular parallelepiped shape, and the protruding portion 12 protrudes above the protruding portion 12 to a position forming a space of a sufficient width for connecting an electric wire to the terminal member 3. .

Further, the base 2 has a lid 14 rotatably supported by a shaft 13 on an upper portion thereof, and the lid 14 has a closed position shown by a broken line and an open position shown by a chain double-dashed line. It is designed to rotate between. The lid 14 is moved to the open position when the electric wire is attached to and detached from the terminal member 3, and is kept in the closed position in other cases to prevent foreign matter from entering the compartments 4 and 5. It is like this.

The terminal member 3 includes a terminal fitting 15 embedded in the terminal pedestals 6 and 9, a washer 16 arranged on the terminal fitting 15, and a screw 17 screwed into a screw hole provided in the terminal fitting 15. Has become. The terminal fitting 15 is made of an elongated conductive metal, and has one end bent at a right angle and press-fitted into a slit provided in the terminal pedestals 6 and 9. Further, the other end of the terminal fitting 15 penetrates a slit provided on the rear surface of the compartments 4 and 5, and is electrically connected to a printed circuit board 18 arranged on the back side of the compartment 5.

An indicator (not shown) is provided on the upper surface of the base 2 for confirming the energization of the electric wire connected to the terminal member 3, and the printed circuit board 19 for controlling the indicator is separated. It is housed in the lower side of the chambers 4, 5 ie in the area widened by the protrusion 12.

When the terminal block 1 having the above-mentioned configuration is mounted on a printed circuit board built in an electric / control device or the like, the space required for connecting the electric wire to the terminal member 3 is always obtained by the protrusion 12. Since other parts are placed close to the terminal block 1, there is no problem.

Although the protrusion 12 is formed integrally with the base 2 in this embodiment, the protrusion 12 may be formed of another member and attached to the base 2.

[0015]

[Effect of device]

 As explained above, when the terminal block of the present invention is mounted on a printed circuit board built into electrical / control equipment, the space required for connecting the electric wire to the terminal member is arranged adjacently. Since it is always obtained regardless of the distance to the parts to be used, it is possible to prevent accidental design mistakes. Also, by providing the protrusion integrally with the base, the space for accommodating the printed circuit board and other parts becomes wider, which facilitates the design.
