Abstract

The present invention provides a shielded connector that can reduce the entire size thereof while preventing an increase in the number of components. A shielding shell includes a shell body provided to an outer side of a housing, and a thermally conductive holding member that supports an insulating container portion of a fuse, so the heat generated by the fuse is dissipated to outside, thereby reducing the space between the housing and the fuse and reducing the entire size of the shielded connector. Also, the shielding shell functions as both a heat dissipation member and a magnetic shield, thus, an increase in the number of components can be prevented.

Claims

1. A shielded connector including terminals provided to ends of at least a pair of electric wires, and a housing that houses the terminals, the shielded connector comprising:

a protection element which is housed in the housing and connected in series between the two terminals to protect a circuit; and

a shielding shell for shielding magnetism attached to an outer surface of the housing so as to cover the protection element,

wherein the shielding shell includes a thermally conductive holding member which holds the protection element and is separated from the terminals.

2. The shielded connector according to claim 1,

wherein the housing is made of an insulating resin,

wherein the protection element is a fuse including

a pair of terminal portions,

a conductive portion which connects the pair of terminal portions to each other, and

an insulating container portion which houses the conductive portion, and

wherein the holding member includes a support portion which supports the container portion.

3. The shielded connector according to claim 2, wherein the support portion is a grip portion that is made of an elastically deformable member and that has an inner side having a shape that follows a side face of the container portion, and wherein the grip portion is elastically deformed outward by the container portion and grips the container portion by inwardly exerted restoring force.

4. The shielded connector according to claim 2, wherein the support portion includes

a pair of clamping portions having an inner side with a shape that follows a side face of the container portion, and configured to clamp the container portion;

and

a fixing portion that fixes the pair of clamping portions so as to keep the container portion clamped by the pair of clamping portions.
