Abstract

A shield connector has a packing. The packing has a plurality of tubular packing bodies that respectively mates with a plurality of tubular portions that respectively accommodating one or more electric wires connected to terminals in a connector housing, and have inner circumferential surfaces making contact with the tubular portions, and a connecting portion that connects the neighboring packing bodies. Each packing body has a first seal surface connected to an outer circumferential surface of the connecting portion in a connector insertion direction side out of an outer circumferential surface, and a second seal surface formed to extend in a circumferential direction and provided in a connector removal direction side. The first seal surface makes contact with the casing. Each second seal surface makes contact with each of a plurality of shield shells.

First claim

What is claimed is:

1 . A packing having elasticity and partially interposed between a connector housing and a conductive casing while the connector housing has an insertion state into a connector through-hole formed in the casing, the packing comprising:
a plurality of tubular packing bodies that respectively mates with a plurality of tubular portions respectively accommodating one or more electric wires connected to terminals in the connector housing, and have inner circumferential surfaces making contact with the tubular portions; and a connecting portion that connects the neighboring packing bodies, wherein a first seal surface connected to an outer circumferential surface of the connecting portion is provided in a connector insertion direction side out of an outer circumferential surface of each of the packing bodies, a second seal surface extending in a circumferential direction is formed in a connector removal direction side opposite to the connector insertion direction out of the outer circumferential surface of each of the packing bodies, the first seal surface makes contact with the casing, the second seal surface has an end of the connector insertion direction making contact with the casing and a portion buried in the connector housing, and the second seal surface makes contact with each of a plurality of shield shells that encapsulate each electric wire accommodated in each of the tubular portions.

2 . The packing according to claim 1 , wherein
the connecting portion has a cavity, and the cavity is blocked by an insertion member other than the packing.

3 . The packing according to claim 1 , wherein
the connecting portion has at least an opening formed in the connector removal direction, and a cavity is provided to have a portion inserted into the connector housing from the opening in the insertion state.

4 . A shield connector comprising:
two or more electric wires each of which is connected to a terminal; a connector housing provided with at least one or more tubular portions respectively mating with the electric wires to accommodate and hold each of the electric wires; and a plurality of shield shells each of which has an end of a connector insertion direction making contact with a conductive casing and a portion buried in the connector housing, each of the shield shells encapsulating each of the electric wires; and an elastic packing, wherein the packing is partially interposed between the connector housing and the casing while the connector housing has an insertion state into a connector through-hole formed in the casing, the packing has a plurality of tubular packing bodies that respectively mates with the plurality of tubular portions and have inner circumferential surfaces making contact with the tubular portions, and a connecting portion that connects the neighboring packing bodies, a first seal surface connected to an outer circumferential surface of the connecting portion is provided in a connector insertion direction side out of an outer circumferential surface of each of the packing bodies, a second seal surface extending in a circumferential direction is formed in a connector removal direction side opposite to the connector insertion direction out of the outer circumferential surface of each of the packing bodies, the first seal surface makes contact with the casing, and each of the second seal surfaces makes contact with each of the shield shell.
