Abstract

A connector has a shielding structure configured by: a shield shell, which has in the front end a tubular shielding portion that surrounds, accommodates, and fixes a resin housing, in the rear end, a barrel portion that crimps and fixes a sheath of a cable, and, between the shielding portion and the barrel portion, an opening portion that is upwardly opened; and a shield cover, which is attached from the upper side to the opening portion of the shield shell. Stoppers that limit rearward movement of the resin housing by causing a plate surface to be butted against a rear end surface of the resin housing that is fixed at the normal position in the shielding portion are disposed in the shield cover.

Claims

1. A connector including:

metal terminals each having, in a front end, a contacting portion that is to be electrically connected to a fitting counter connector, and, in a rear end, a connecting portion that is to be connected to a core wire of a cable; and

a resin housing that holds the metal terminals,

the connector having a shielding structure configured by;

a shield shell which is formed by sheet-metal working, and which has in a front end a tubular shielding portion that surrounds, accommodates, and fixes the resin housing, in a rear end, a barrel portion that crimps and fixes a sheath of the cable, and, between the shielding portion and the barrel portion, an opening portion that is upwardly opened; and

a shield cover which is formed separately from the shield shell by sheet-metal working, and which is attached from an upper side to the opening portion of the shield shell, wherein

a stopper and a plate surface are provided by the shield cover, said plate surface being provided by said stopper and being formed by bending a part of the shield cover so as to be inwardly directed, said plate surface being positioned to abut against a rear end surface of the resin housing or a rearwardly directed step surface that is formed on an outer wall of the resin housing, to limit rearward movement of the resin housing that is fixed at the normal position in the shielding portion.

2. A connector including:

metal terminals each having, in a front end, a contacting portion that is to be electrically connected to a fitting counter connector, and, in a rear end, a connecting portion that is to be connected to a core wire of a cable; and

a resin housing that holds the metal terminals,

the connector having a shielding structure configured by;

a shield shell which is formed by sheet-metal working, and which has in a front end a tubular shielding portion that surrounds, accommodates, and fixes the resin housing, in a rear end, a barrel portion that crimps and fixes a sheath of the cable, and, between the shielding portion and the barrel portion, an opening portion that is upwardly opened; and

a shield cover which is formed separately from the shield shell by sheet-metal working, and which is attached from an upper side to the opening portion of the shield shell, wherein

stoppers are disposed in the shield cover, and the stoppers limit rearward movement of the resin housing by causing a plate surface to be butted against a rearwardly directed step surface which is formed on a rear end surface or outer wall of the resin housing that is fixed at the normal position in the shielding portion, wherein

the shield cover has;

a cover piece portion which, when the shield cover is attached from the upper side to the opening portion of the shield shell, covers an upper opening surface of the opening portion; and

a pair of attaching piece portions which are downwardly extended from both sides of the cover piece portion, to overlap with outer side parts of side surfaces of the opening portion, respectively,

the stoppers are disposed respectively in the pair of attaching piece portions, each of the pair of stoppers is configured by a metal piece which is forwardly projected from the corresponding attaching piece portion, and which is bent into an L-like shape to direct a tip end to an inner side,

a pair of slits are disposed in both side parts of the shielding portion, tip end portions of the pair of stoppers which are inwardly directed being fitted from the upper side into the slits when the shield cover is attached from the upper side to the opening portion of the shield shell, respectively, thereby causing plate surfaces of the pair of stoppers to be butted against the rearwardly directed step surface which is formed on the rear end surface or outer wall of the resin housing that is accommodated at the normal position in the shielding portion, and,

when the shield cover is to be attached from the upper side to the opening portion of the shield shell, the pair of stoppers function as a guide to the normal attachment position of the shield cover.
