Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an external connection terminal device for electrical equipment, and is designed to extremely easily assemble the device and replace each external connection terminal component.

In a conventional external connection terminal device, for example, as shown in FIGS. 1 and 2, each external connection terminal component 2 to
6, and then attach the terminal board to the printed circuit board 7.
At the same time, each of the external connection terminal parts 2 to 6 was soldered to electrically connect to a circuit network (not shown) on the printed circuit board 7.

Therefore, in such a configuration, each external connection terminal component is mounted on the printed circuit board with each screwed to the terminal board, so when replacing each external connection terminal component,
When removing the terminal board, all screws had to be removed.

Therefore, replacing each external connection terminal required a great deal of effort and required a large number of parts.

The present invention was developed in consideration of these points, and by making the configuration of the terminal board unique to this invention, it is extremely easy to replace each external connection terminal part, and the number of parts is reduced. The present invention aims to provide an external connection terminal device for electrical equipment.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a schematic side sectional view of the external connection terminal device, FIG. 4 is a schematic side sectional view showing its assembled state, and FIG. 5 is a perspective view of the terminal board.

Reference numeral 8 denotes a printed circuit board on which electrical components (not shown) and a circuit network (not shown) for connecting them are provided.

9, 10.11 are external connection terminal parts having mounting protrusions 12, 13.14, respectively, and the external connection terminal parts 9, 10.
11 are mounted on the printed circuit board 8 at predetermined intervals, and are electrically connected to the circuit network of the printed circuit board 8 (i.e., by soldering, etc.).

Reference numeral 15 denotes a terminal board having a cross-sectional shape, and its upright piece is provided with a plurality of through holes 16, 17, 18 for exposing the front end portions of the external connection terminal parts 9, 10, 11. and the external connection terminal parts 9, 10.
Gap 19 into which each of the mounting protrusions 12, 13, and 14 of 11 fit.
, 20, 21 and a plurality of elastic tongues 22, 23, 24 whose tip edges abut against each of the mounting protrusions, respectively.

Reference numeral 25 denotes a boss provided on a horizontal piece of the terminal board 15, and the terminal board 15 is so constructed that its tip surface sometimes comes into contact with the printed circuit board 8 to position the terminal board 15 when the terminal board 15 is mounted.

The assembly process of the device of the present invention will be briefly explained below.

First, as described above, the external connection terminal parts 9, 10.
11, and connect the printed circuit board 8 to the terminal board 15 as shown in FIG.
Insert from the one end with the (in the direction of arrow A).

With the insertion, the respective mounting protrusions 12, 13.
24 are fitted into the gaps 19, 20, and 21 respectively while pressing in the direction of arrow B (dotted line position), and the terminal board is brought into a state in which they abut against the tip edges of the elastic tongues, respectively. 15 is positioned (that is, held) on the printed circuit board 8 and also positions each external connection terminal component.

Also, at the same time as the above-mentioned fitting, the external connection terminal parts 9, 10° 11
The front ends of the terminal board 15 are exposed to the outer surface of the terminal board 15 through the through holes 16, 17, 18, respectively, and the terminal board 15 Securely position (i.e. hold) on the printed circuit board 8 compatible with external connection terminal parts 9.10.11
be done.

Incidentally, in order to further ensure the positioning (that is, holding) of the terminal board, it is also possible to provide a screw hole on the boss body and the printed circuit board with which it comes into contact, and to screw the boss body onto the chassis.

As described above, according to the device of the present invention, the cross section is formed into an abbreviated shape, and the upright piece is provided with a plurality of through holes for exposing each end of the external connection terminal component, and the horizontal piece is provided with the external connection terminal component. By using a terminal board unique to the present invention that is provided with a plurality of elastic tongues that abut against each mounting protrusion, when the terminal board is attached to a printed circuit board with an external connection terminal component attached to one end, The tip edges of the elastic tongues maintain abutment with each mounting protrusion of the external connection terminal component fitted into each gap, and this abutment allows the terminal board itself to be mounted and positioned, as well as the printed circuit board. The external connection terminal parts, which are installed independently at a predetermined interval at one end and therefore have uneven openings, are also positioned, and each end of the external connection terminal parts is exposed at a certain level. This has the effect of exposing the outer surface of the terminal board through each through hole at the same time.

Furthermore, since the board is attached only by fitting using elastic tongues instead of screwing as in the conventional case,
It has the advantage of reducing the number of parts and making it easy to replace each external connection terminal part, so it has extremely high practical value.
