BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal cap, and more specifically, covers a terminal at a portion where a plate-shaped terminal connected to the tip of a wire harness for an automobile is attached to a male screw terminal by a nut.
The present invention relates to a terminal cap for preventing a connection portion between the terminal and an electric device from coming into contact with other parts and protecting the terminal from moisture, dust and the like.

[0002]

2. Description of the Related Art As this type of terminal cap, for example, a terminal cap shown in FIGS. 7 and 8 has been proposed. In the terminal cap 1 shown in FIG. 7, a connection side arrangement portion 3 which is formed of a cylindrical body having upper and lower ends open in the figure and accommodates the connection portion 2 a of the terminal 2,
The base-side arrangement portion 4 for accommodating the base 2c of the terminal 2 provided with b is provided continuously. In addition, the terminal cap 1 includes first and second lids 5 and 6 for closing upper sides of the connection side arrangement part 3 and the base side arrangement part 4 in the drawing. In the figure, reference numeral 7 denotes a connection terminal of the electric device 8.

When the terminal 2 is covered with the terminal cap 1, the connecting portion 2a of the terminal 2 is first arranged in the connecting side arrangement portion 3, and the base 2c and the end 9a of the electric wire 9 are arranged on the base side. After the arrangement in the part 4, the second lid part 6 is closed. Next, the connection side arrangement portion 3 is placed on the connection terminal 7 from above in the figure, and the bolt portion 1 of the connection terminal 7 is placed.
0 is inserted into the through hole 2d of the connection portion 2a. further,
The nut 12 is screwed into the bolt part 10 to fasten the connection part 2 a to the connection terminal 7, and then the opening 3 a of the connection side arrangement part 3 is closed with the first lid 5.

The terminal cap 1 shown in FIG. 8 has a first lid 5 hinged to a second lid 6 hinged to the base side arrangement portion 4.

[0005]

In the conventional terminal caps 1 described above, the accommodation space formed by the connection side arrangement portion 3 and the first lid portion 5 which covers the connection side arrangement portion 3 is one terminal. And the connection side arrangement portion 3 and the first lid portion 5.
, The structure is such that only one terminal 2 can be attached to one terminal cap 1. Therefore, when it is necessary to attach a plurality of terminals 2 to one connection terminal 7, there is a problem that the terminal cap 1 cannot be used. Further, when the terminal cap 1 must be mounted, the connection terminals 7 and the terminal caps 1 are required as many as the number of the terminals 2, resulting in a problem that the cost is increased and the workability of the mounting is poor.

The present invention has been made to solve the above problem, and has as its object to provide a terminal cap capable of attaching a plurality of terminals to one connection terminal.

[0007]

And a base portion 21d having an electric wire caulking portion 21c for caulking the end portion 22a.

With the above configuration, the terminal cap 2
In order to cover the terminal 17 and another terminal 21 with 0, first, the connecting portion 17c of the terminal 17 is arranged in the connecting side arrangement portion 20a, and the base 17e and the end 18a of the electric wire 18 are connected to the base side arrangement portion 20b. After that, the second lid portion 20c is closed by the hinge portion 20d to close the base side arrangement portion 20b, and the lock hole 20e and the lock claw 2 are closed.
At 0f, the second lid portion 20c is locked to the base side arrangement portion 20b.

Next, the connection side arrangement portion 20a of the terminal cap 20 is put on the connection terminal 16 from above, and the bolt portion 16a of the connection terminal 16 is connected to the connection portion 1a of the terminal 17 above.
7c is inserted into the through hole 17a.
The detent claw 17b is engaged with 6b.

Thereafter, the through hole 21b of the connecting portion 21a of the terminal 21 is inserted into the bolt portion 16a, and is superposed on the connecting portion 17c of the terminal 17 described above. At this time, the wire connecting side of the connecting portion 21a of the terminal 21 passes through the slit 20j.

Next, the nut 23 is screwed into the bolt portion 16a, and the connecting portions 17c and 21a of the terminals 17 and 21 are tightened and fixed to the connecting terminals 16. After that, the first lid portion 20g is closed by the hinge portion 20h, and the connection side arrangement portion 20 is closed.
a is closed, and the first lid 20 is locked with the lock claw 20i and the lock hole.
g is locked to the connection side arrangement part 20a.

The terminal 21 is connected to the slit 20
It can be installed from the required direction in the range S of j.
(See the two-dot chain line in FIG. 2). The base 2 of the terminal 21
1d is covered and protected by a heat-shrinkable tube.

In the above embodiment, another terminal 21 is 1
However, if the height of the slit 20j is increased, several other terminals 21 can be further overlapped and attached.

[0025]

As is apparent from the above description, the terminal cap of the present invention penetrates the slit formed between the connection side arrangement portion of the terminal cap and both outer peripheral walls of the first lid portion, and allows the terminal cap to pass through. A connection portion of a terminal different from the terminal protected by the cap is inserted so as to overlap with a connection portion of the previous terminal. Therefore, a plurality of terminals can be attached to one connection terminal in a state protected by the terminal cap, so that the number of parts is reduced, the cost is reduced, and the assemblability is improved.
