Description

[Detailed explanation of the idea] [Application field] The present invention relates to a terminal device for connecting electric wires.

[Background technology]

In this type of terminal device, as shown in FIG. 4, the terminal screw 23 screwed into the upper plate 22 of the terminal fitting 21 is operated to press the stopper 24 downward and placed on the lower plate 25 of the terminal fitting 21. The electric wire 27 is pressed against the terminal plate 26 to connect the electric wire 27. This terminal device is housed in a cover 28 and a device stand 29, and the cover 28 has a stopper portion 30 formed at the rear of the terminal fitting 21 so that when the electric wire 27 is inserted into the terminal fitting 21, it does not come into contact with other electrical components at the rear. ing.

Therefore, if the above is the case, the stopper part 3
0 is made of synthetic resin, so there is a risk of damage if the electric wire 27 is firmly inserted, and if the stopper part 30 is formed integrally with the cover 28, the rear end of the terminal fitting 21 and It is difficult to reduce the gap t between the stopper part 30 and the gap t.
There was a fear that dirt and foreign matter from the outside could enter and adversely affect the internal parts.

[Purpose of invention]

The object of the present invention is to provide a terminal device which has a sufficient stopper function for insertion of electric wires and which reduces the intrusion of dust, foreign matter, etc. from the outside.

[Disclosure of invention]

Therefore, the terminal device of the present invention includes a box-shaped terminal fitting comprising a terminal screw, an upper plate into which the terminal screw is screwed, a lower plate opposite to the upper plate, and left and right side plates connecting the upper and lower plates; A terminal board placed on a lower plate of a terminal metal fitting, a device stand on which the terminal plate is placed, which has a recess for mounting the lower plate of the terminal metal fitting and is located behind the terminal metal fitting, and the terminal metal fitting. A stopper fitting consisting of a vertical plate that presses against the rear ends of the upper plate and the left and right side plates, and a horizontal plate located on the terminal plate, and a fixing that penetrates the horizontal plate of the stopper fitting and the terminal plate and bites into the device base. By using the studs, it is possible to stop the insertion of the electric wire without damaging the vertical plate of the stopper metal fitting, and to reduce the intrusion of dust and foreign matter from the outside.

Embodiment The present invention will be explained based on FIGS. 1 to 3 showing an embodiment of the present invention. Reference numeral 1 indicates a terminal screw, and 2 indicates a terminal fitting into which the terminal screw 1 is screwed. An upper plate 4 provided with screw holes 3 for screwing together, a lower plate 5 facing the upper plate 4, and left and right side plates 6, 6 connecting the upper and lower plates 4, 5 form a box shape with front and rear openings. Reference numeral 7 denotes a terminal plate, the front part of which is placed on the lower plate 5 of the terminal fitting 2, and the rear part extending from the rear end of the terminal fitting 2 and having a fixed contact 8 attached to its tip. Reference numeral 9 denotes a stopper, which is formed by bending the horizontal plate 10 located between the terminal plate 7 and the upper plate 4 of the terminal fitting 2 and the front end of the horizontal plate 10 upward to form the front part of the upper plate 4 of the terminal fitting 2. A front vertical plate 11 disposed on the front vertical plate 11 and a guide piece 1 located in front of the right side plates 6, 6 of the terminal fitting 2 provided on both sides of the front vertical plate 11.
It consists of 2 and 12. Reference numeral 13 denotes a device stand, which has a recess 14 in which the lower plate 5 of the terminal fitting 2 is mounted, and a terminal plate 7 located behind the terminal fitting 2 is placed thereon. 15 is a cover that covers the table 13;
It surrounds the terminal screw 1, the terminal fitting 2, the terminal plate 7, and the stopper 9. Reference numeral 16 denotes a stopper fitting, which includes a vertical plate 17 that presses against the rear end of the upper plate 4 and left and right side plates 6, 6 of the terminal fitting 2 to close the rear opening of the terminal fitting 2, and a horizontal plate 18 located on the terminal plate 7. configured. In addition, vertical plate 17
To press the terminal fitting 2, before attaching the stopper fitting 16, form an obtuse angle between the vertical plate 17 and the horizontal plate 18, and apply force in a direction to bend this angle at right angles. It is obtained by positioning and mounting the plate 18 on the terminal plate 7. Reference numeral 19 denotes a fixing stud which penetrates through the horizontal plate 18 of the stopper metal fitting 16 and the terminal plate 7 and bites into the device base 13 so that both 16 and 7 are fixed.
is fixed to the table 13.

[Effect of idea]

In the above configuration, the vertical plate of the stopper fitting closes the rear opening of the terminal fitting, so since it is made of metal, it stops the electric wire inserted from the front without damaging it and prevents it from entering the inside. Moreover, since the vertical plate of the stopper metal fitting is pressed into contact with the terminal metal fitting, the gap between them is minimized, reducing the intrusion of dust and foreign matter, and the stopper metal fitting can be installed on the instrument stand at the same time as the terminal plate, simplifying assembly. Furthermore, due to the elastic force of the stopper metal fittings pressing against the terminal metal fittings, the reaction force acts on the horizontal plate as well, which has the effect of preventing the fixing rivets from coming off.
