## Abstract

The electrical connector with a filter according to the present invention comprises a shield frame, a filter unit having holes, contact elements to be inserted respectively into the holes, and a leaf spring interposed between the shield frame and the filter unit, the filter unit having a filter function corresponding to the holes, and a ground electrode; the ground electrode and the shield frame being electrically connected by the leaf spring; and the filter unit and the shield frame being mechanically secured and held by the leaf spring. Also, the electrical connector with a filter according to the present invention comprises a shield frame, a filter unit having holes, contact elements to be inserted respectively into the holes and each having a stopper, a fixture for allowing the contact elements to be inserted, a leaf spring interposed between the shield frame and the filter unit, and a body, the filter unit having a filter function corresponding to the holes and a ground electrode; the ground electrode and the shield frame being electrically connected by the leaf spring; the filter unit and the shield frame being mechanically secured and held by the leaf spring; and the contact elements being pressed against the filter unit by the fixture through the stoppers.

## Claims

### Claim 1

An electrical connector comprising a shield frame, a filter unit having holes, contact elements to be inserted respectively into said holes, and a leaf spring interposed between said shield frame and said filter unit,
said leaf spring comprising at least one of a convex and a concave portion to create at least one shield frame contact portion and at least one filter unit contact portion, a remaining portion of said leaf spring being substantially planar,
said filter unit having a filter element corresponding to respective ones of said holes, and a ground electrode;
said filter element comprising a conductor and a dielectric substance and/or ferrite, which are formed on an alumina substrate by the thick-film printing technique;
said filter unit allowing said contact elements to be retained and secured therein;
said ground electrode and said shield frame being electrically connected by said leaf spring being electrically conductive; and
said filter unit and said shield frame being mechanically secured and held by said leaf spring.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, further comprising a body, and said shield frame, said filter unit, said leaf spring and said body being secured to one another.

### Claim 3 (depends on 1)

The electrical connector according to claim 1, wherein said dielectric substance comprises at least two compounds selected from the group consisting of Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3, pb(Zn.sub.1/3 Nb.sub.2/3)O.sub.3 and PbTiO.sub.3.
