Abstract

Abstract A grommet, to be installed on a wire harness penetrating through two panels, comprising: a first member (11) and a second member (12), wherein the wire portion (21) is inserted into the large-diameter portion (15), the rib (22) is brought into contact with the stepped portion (16), and the cut-out portion (17) is engaged by the locking projections (23, 24) by adjusting the lengthwise and circumferential directions of the wire portions (14) and (21), so as to connect the wire portion (14) of the first member (11) and the wire portion (21) of second member (12) with each other.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 274 words
A grommet, to be installed on a wire harness penetrating through two panels, comprising: a first member and a second member, the first member having: a cylindrical wire portion having a leading end and a second end; a panel-installing portion disposed at the second end of the wire portion; a large-diameter portion disposed at the leading end of the wire portion of the first member; a stepped portion disposed at an end of the large-diameter portion; and a cut-out portion formed axially in a predetermined length from a leading end of the large-diameter portion, the cut-out portion occupying substantially one half of the circumference of the large-diameter portion and having two axially-disposed inner surfaces and a third inner surface, and the second member having: a cylindrical wire portion and a panel-installing portion disposed at an end of the wire portion; a rib disposed on the peripheral surface of the wire portion at the leading end of the second member; and axially-disposed locking projections comprising a pair of first projections adapted to engage the axially-disposed inner surfaces of the cut-out portion, and a second locking projection, extending circumferentially between the first locking projections and adapted to be brought into contact with the third inner surface, in which: the wire portion is adapted to be inserted into the large-diameter portion, the rib is adapted to be brought into contact with the stepped portion, and the cut-out portion is adapted to be engaged by the locking projections by adjusting the lengthwise and circumferential direction of the wire portions, so as to connect the wire portion of the first member and the wire portion of the second member.
Claim 2
Dependent Claim 274 words
A grommet, to be installed on a wire harness penetrating through two panels, comprising: a first member and a second member, the first member having: a cylindrical wire portion having a leading end and a second end; a panel-installing portion disposed at the second end of the wire portion; a large-diameter portion disposed at the leading end of the wire portion of the first member; a stepped portion disposed at an end of the large-diameter portion; and a cut-out portion formed axially in a predetermined length from a leading end of the large-diameter portion, the cut-out portion occupying substantially one half of the circumference of the large-diameter portion and having two axially-disposed inner surfaces and a third inner surface, and the second member having: a cylindrical wire portion and a panel-installing portion disposed at an end of the wire portion; a rib disposed on the peripheral surface of the wire portion at the leading end of the second member; and axially-disposed locking projections comprising a pair of first projections adapted to engage the axially-disposed inner surfaces of the cut-out portion, and a second locking projection, extending circumferentially between the first locking projections and adapted to be brought into contact with the third inner surface, in which: the wire portion is adapted to be inserted into the large-diameter portion, the rib is adapted to be brought into contact with the stepped portion, and the cut-out portion is adapted to be engaged by the locking projections by adjusting the lengthwise and circumferential direction of the wire portions, so as to connect the wire portion of the first member and the wire portion of the second member.
Claim 3
Dependent Claim 33 words
The grommet of claim 1, wherein, the axially-disposed locking projections comprise a first end and a second end and the circumferentially-disposed locking projection extends between the first ends of the axially-disposed locking projections.
Claim 4
Dependent Claim 17 words
The grommet of claim 1 wherein the third inner surface of the cut-out portion is circumferentially disposed.
Claim 5
Dependent Claim 331 words
A grommet, to be installed on a wire harness penetrating through two panels, comprising: a first member and a second member, the first member having: a cylindrical wire portion having a leading end and a second end; a panel-installing portion disposed at the second end of the wire portion; a large-diameter portion disposed at the leading end of the wire portion of the first member, the leading end including a rib projecting circumferentially therefrom; a stepped portion disposed at an end of the large-diameter portion; and a cut-out portion formed axially in a predetermined length from a leading end of the large-diameter portion and having an axially-disposed inner surface; and the second member having: a cylindrical wire portion having a leading end a second end, and a panel-installing portion disposed at the second end of the wire portion; a first rib disposed on the peripheral surface of the wire portion at the leading end of the second member, and a second rib circumferentially disposed on the peripheral surface of the wire portion of the second member and spaced from the first rib such that the distance between the leading end of the wire portion of the second member and the second rib is equal to the length of the large-diameter portion of the first member; the second rib on the wire portion of the second member being adapted to contact the rib extending circumferentially from the leading end of the wire portion of the first member; and axially-disposed locking projections adapted to engage the axially-disposed inner surface of the cut-out portion, in which: the wire portion is adapted to be inserted into the large-diameter portion, the rib is adapted to be brought into contact with the stepped portion, and the cut-out portion is adapted to be engaged by the locking projections by adjusting the lengthwise and circumferential direction of the wire portions, so as to connect the wire portion of the first member and the wire portion of the second member.
Claim 6
Dependent Claim 331 words
A grommet, to be installed on a wire harness penetrating through two panels, comprising: a first member and a second member, the first member having: a cylindrical wire portion having a leading end and a second end; a panel-installing portion disposed at the second end of the wire portion; a large-diameter portion disposed at the leading end of the wire portion of the first member, the leading end including a rib projecting circumferentially therefrom; a stepped portion disposed at an end of the large-diameter portion; and a cut-out portion formed axially in a predetermined length from a leading end of the large-diameter portion and having an axially-disposed inner surface; and the second member having: a cylindrical wire portion having a leading end a second end, and a panel-installing portion disposed at the second end of the wire portion; a first rib disposed on the peripheral surface of the wire portion at the leading end of the second member, and a second rib circumferentially disposed on the peripheral surface of the wire portion of the second member and spaced from the first rib such that the distance between the leading end of the wire portion of the second member and the second rib is equal to the length of the large-diameter portion of the first member; the second rib on the wire portion of the second member being adapted to contact the rib extending circumferentially from the leading end of the wire portion of the first member; and axially-disposed locking projections adapted to engage the axially-disposed inner surface of the cut-out portion, in which: the wire portion is adapted to be inserted into the large-diameter portion, the rib is adapted to be brought into contact with the stepped portion, and the cut-out portion is adapted to be engaged by the locking projections by adjusting the lengthwise and circumferential direction of the wire portions, so as to connect the wire portion of the first member and the wire portion of the second member.
