Abstract

The connector provided with at least one capacitor comprises: a resin connector housing; a metallic shield casing; and at least one connector terminal formed with, in particular a flexible portion to absorb thermal deformation of the resin connector housing relative to the metallic shield casing due to a difference in thermal expansion coefficient between the two, caused when the connector terminal is soldered to the capacitor or a printed circuit board.

Claims

1. A connector provided with a capacitor, comprising:

(a) a connector housing;

(b) a shield casing engaged with said connector housing;

(c) at least one capacitor having an outer electrode soldered to said shield casing and an inner electrode;

(d) at least one connector terminal passed through said connector housing and said capacitor, including;

(1) a male tab portion;

(2) a middle portion pressure-fitted to said connector housing for terminal support;

(3) a terminal pin portion soldered to the inner electrode of said capacitor at an inner end thereof and to a printed circuit board at an outer end thereof; and

(4) a flexible portion formed between said middle portion and the inner end of said terminal pin portion;

wherein said connector terminal is a strip-shaped terminal formed with a S-shaped bent flexible portion when seen in a plan view.

2. The connector provided with a capacitor of claim 1, wherein a width W of said S-shaped bent flexible portion is narrower than that W of said male tab portion and a thickness t₁ of said S-shaped bent flexible portion is thinner than that t of said male tab portion and said terminal pin portion.

3. The connector provided with a capacitor of claim 1, wherein said terminal pin portion is further formed with a narrower width portion for stress absorption.

4. The connector provided with a capacitor of claim 1, wherein said middle portion is further formed with a pair of stopper portions for locating said connector terminal to said connector housing.

5. A connector provided with a capacitor, comprising:

(a) a connector housing;

(b) a shield casing engaged with said connector housing;

(c) at least one capacitor having an outer electrode soldered to said shield casing and an inner electrode;

(d) at least one connector terminal passed through said connector housing and said capacitor, including;

(1) a male tab portion;

(2) a middle portion pressure-fitted to said connector housing for terminal support;

(3) a terminal pin portion soldered to the inner electrode of said capacitor at an inner end thereof and to a printed circuit board at an outer end thereof; and

(4) a flexible portion formed between said middle portion and the inner end of said terminal pin portion;

wherein said connector terminal is a strip-shaped terminal formed with a S-shaped bent flexible portion when seen in a plane view and into a recessed shape when seen in a side view.

6. The connector provided with a capacitor of claim 5, wherein a width W of said S-shaped bent flexible portion is narrower than that W of said male tab portion and a thickness t₁ of said S-shaped bent flexible portion is thinner than that t of said male tab portion and said terminal pin portion.

7. The connector provided with a capacitor of claim 5, wherein said terminal pin portion is further formed with a narrower width portion for stress absorption.

8. The connector provided with a capacitor of claim 5, wherein said middle portion is further formed with a pair of stopper portions for locating said connector terminal to said connector housing.
