Conventionally, there is a connection device of this type as shown in FIG. 6 (see Japanese Utility Model Application No. 62-33182).
In the figure, 1 is a male connector, and a terminal plate 4a of a terminal 4 is inserted through a side opening 3 of a housing 2.
An elastic contact piece 4b formed by folding back is exposed. 5 is a male connector, which has a recess 8 formed in a case 7 such as an electrical connection box housing the FPC 6;
An electrical contact portion, which is a part of the circuit conductor 9 of the FPC 6, is bent and placed along the wall surface of the recess 8. When the male connector 1 is inserted into the male connector 5, the elastic contact piece 4b and the circuit conductor 9 come into contact as shown in FIG. 7, and the FPC 6 and the electric wire w crimped to the terminal 4 are electrically connected.

According to the prior art, the stability of the electrical connection between the circuit conductor 9 and the terminal 4 depends on the contact pressure of the elastic contact piece 4b. However, since the elastic contact piece 4b is exposed to the outside, it has the disadvantage that it is easily deformed by external force or the contact resistance is easily changed due to the adhesion of foreign matter such as dust. In addition, if the terminal 4 is made of a highly elastic material such as beryllium copper or phosphor bronze to increase the contact pressure,
It is difficult to mold and has high electrical resistance, making it difficult to obtain a stable electrical connection.
