Description

[Detailed Description of the Invention] The present invention relates to an improvement of a terminal device for electrical components such as switches and sockets.

Conventionally, the terminals of these electrical components were attached by caulking with rivets inserted through rivet insertion holes provided in the base, but the terminals and rivets, which are caulked to maintain contact, are exposed to outside air due to use over time. It has the disadvantage that corrosion progresses when touched, increasing contact resistance.

Furthermore, since this location is not a location where external lead wires are connected, it is important to insulate this location in order to reduce the exposed portion of the live part as much as possible.

Furthermore, when soldering the lead wire to the terminal portion, flux flows and enters between the terminal portion and the rivet, which deteriorates the contact therebetween, which is a significant drawback.

The present invention is a terminal device for electrical components that eliminates the above-mentioned drawbacks.
An example of this will be described below.

FIG. 1 is a side cross section of the terminal device, showing a recess 2 provided in the base 1 of the electrical component, a rivet insertion hole 3 provided in this recess 2,
A terminal 4 that is fitted into the recess 2 and has one end bent to protrude outside, and this terminal.

4, a rivet 5 inserted through the rivet insertion hole and caulked, and an insulating agent 6 filled in the recess 2.

I is a lead wire soldered to one end of the terminal 4.

FIG. 2 shows the operation of dropping the insulating agent 6.

Based on the above configuration, in the present invention, when the insulating agent 6 is dropped, the insulating agent can be satisfactorily filled into the recess 2 without the insulating agent protruding from the recess 2.

Therefore, the dripping operation proceeds smoothly and the contact portion between the rivet 5 and the terminal 4 does not come into contact with the outside air, so that the contact resistance hardly increases over time.

In addition, since the positioning of the terminal 4 is easy, the insertion of the rivet 5 becomes easy and the caulking work becomes smooth, and since the terminal 4 can be prevented from rotating, the contact area between the rivet 5 and the terminal 4 is It never loosens.

Furthermore, the flux that flows out when the lead wire T is soldered to one end of the terminal 4 does not enter the contact area between the rivet 5 and the terminal 4, and good contact between this area can be maintained.

Next, another embodiment of the present invention will be described.

As shown in FIGS. 3 and 4, by providing the convex peripheral edge part 8 on the base 1, the concave part 2 is formed and the convex peripheral edge part 8 is formed.
An insulating cap 9 is fitted to the outer peripheral edge of the terminal 4, and a lead wire 7 connected to the terminal 4 is drawn out through the insulating cap 9.

The insulating cap 9 may be simply fitted onto the convex peripheral portion 8, but may also be fixed by adhesive.

Therefore, in this embodiment, the live parts can be completely insulated and protected.

As described above, the terminal device for electrical components of the present invention can prevent corrosion at the contact area between the rivet and the terminal, and can also cover the live part at this point with a simple configuration. Since the flux that flows out when soldering to one end of the rivet does not enter the contact area between the rivet and the terminal, it has the remarkable effect that the contact in this area is not deteriorated at all.
