DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a connection structure of a plate terminal applied to a mirror unit of a sun visor or the like.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a conventional structure for connecting plate terminals of this type. In these figures, reference numeral 21 denotes a plate terminal made of a thin metal material. The plate terminal 21 includes a base 21 a and a connecting portion 21 c having a chrysanthemum-shaped insertion hole 21 b. The base 21 a is fixed to the unit base 23, and the fitting terminal 24 is formed through a fitting hole 24 formed in the unit base 23. Connection part 21
c is projected outside the unit base 23.

Reference numeral 25 denotes a harness connected to the plate terminal 21. The harness 25 has its core exposed at its distal end 25a and is solidified with solder.
The harness 25 is connected to the plate terminal 21 by inserting the tip 25a into the insertion hole 21b of the connection portion 21c of the plate terminal 21.

[0004]

However, in the conventional connection structure of the plate terminals 21, as shown in FIG. 7, when the tip 25a of the harness 25 is inserted into the insertion hole 21b, the plate terminal 21 bends and the harness 25 is bent. Tip 2
The force for inserting 5a is absorbed. For this reason, it becomes difficult to insert the tip 25a of the harness 25 against the insertion resistance of the plate terminal 21 in the insertion hole 21b. Further, since the distance between the insertion hole 21b of the plate terminal 21 and the unit base 23 is reduced due to the bending of the plate terminal 21, the insertion length of the tip 25a of the harness 25 cannot be sufficiently secured, and the harness 25 is not connected to the plate terminal. After the connection to the harness 25, the harness 25 may be pulled out.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. A plate terminal capable of easily inserting a harness, securing the insertion length of the tip of the harness, and preventing the harness from coming off. The purpose of the present invention is to provide a connection structure.

According to the above configuration, the bending of the plate terminal when the harness is inserted is prevented by the bending preventing portion. For this reason, the force for inserting the tip of the harness is not absorbed by the bending of the plate terminal, and the tip of the harness can be inserted against the insertion resistance in the insertion hole of the plate terminal. Also, since the bending of the plate terminal is prevented,
The insertion length of the distal end of the harness can be ensured without reducing the distance between the insertion hole of the connection portion and the unit base.

Therefore, the harness can be easily inserted, and the harness can be prevented from coming off after being connected to the plate terminal.

According to the first aspect of the present invention, when the tip of the harness is inserted into the insertion hole of the plate terminal, the plate terminal comes into contact with the projection extending from the unit base to connect the plate terminal. The bending of the portion is prevented.

c, 5c, the bases 4a, 5a are fixed in the terminal mounting portion 7 of the unit base 2, and the connecting portions 4c, 5c are projected out of the unit base 2 through the through holes 9 of the unit base 2. It is. The base 4a of the plate terminal 4 is provided with a contact 4d, and the base 5a of the plate terminal 5 is provided with a clip 5d.

At the tip 6a of the harness 6,
The core is exposed and hardened with solder. The harness 6 has connection holes 4b for connecting portions 4c and 5c of the plate terminals 4 and 5,
The tip 6a is inserted into 5b, whereby the tip 6a is connected to the plate terminals 4,5.

Reference numeral 10 denotes a projection (a deflection preventing portion) for preventing the plate terminals 4 and 5 from bending when the tip of the harness 6 is inserted into the insertion holes 4b and 5b of the plate terminals 4 and 5.
These projections 10 are from units based 2, connecting portions 4c of the respective plate terminals 4 and 5, spaced toward 5c

To
Folded tongue piece 4 bent toward unit base 2
e, 5e. Since the other configuration is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and the description thereof will not be repeated.

In the second embodiment, when the tip 6a of the harness 6 is inserted into the insertion holes 4b, 5b, the bent tongue pieces 4e, 5c of the connecting portions 4c, 5c of the plate terminals 4, 5 are used.
"e" comes into contact with the unit base 2, more specifically, the mirror body 3 integrally attached to the unit base 2. This prevents the connection portions 4c and 5c of the plate terminals 4 and 5 from bending.

For this reason, the insertion holes 4 of the plate terminals 4 and 5
b, 5b, against the insertion resistance at the end 6a of the harness 6
Can be inserted. Further, since the bending of the plate terminals 4 and 5 is prevented, the insertion holes 4 of the plate terminals 4 and 5 are formed.
By pushing the end 6a of the harness 6 until the end 6a of the harness 6 comes into contact with the mirror body 3 without narrowing the distance between the b and 5b and the unit base 2, the end 6a of the harness 6 can be pushed sufficiently. The insertion length of the distal end 6a can be sufficiently ensured, and variation in the insertion length of the distal end 6a of the harness 6 can be prevented.

Therefore, the same effects as those of the plate terminal connection structure of the first embodiment can be obtained.
