Claim 3

A connector according to claim 1, wherein the elastic pushing portion is only provided at the second lock groove of the elastic portion.

Claim 4

A connector according to claim 1, wherein the elastic portion is formed by a pair of longitudinal slits formed in the housing and extending substantially along a direction extending between the ends of the housing, each of the longitudinal slits having a first end between the jaw portion and the first end of the housing and a second end between the jaw portion and the second end of the housing, said elastic portion further being formed by a transverse slit extending between the first ends of the longitudinal slits, the elastic portion having a first end formed by the transverse slit, the projected portion of the elastic portion including a tapered guide surface tapered outwardly and extending from the transverse slit to the second lock groove, portions of the tapered guide surface adjacent the transverse slit substantially conforming to the cross-section of the outer surfaces adjacent the transverse slit for facilitating insertion of the first end of the housing into the mount hole.

Claim 5

A connector according to claim 1, wherein the elastic pushing portion has a free end, the projected portion of the elastic portion and the projection each extending from the outer surfaces of the housing further than the free end of the elastic pushing portion.

Claim 6

A connector according to claim 4, wherein the at least one elastic pushing portion comprises first and second elastic pushing portions disposed respectively on opposite respective sides of said elastic portion.

Claim 7

A connector according to claim 1, wherein the at least one elastic pushing portion is formed unitarily with the jaw portion.

Claim 8

A connector according to claim 6, wherein at least one hole is formed at a location aligned with the at least one elastic pushing portion, and wherein the at least one elastic pushing portion is formed in its unbiased condition to project substantially obliquely into the corresponding lock groove.

Claim 9

A connector according to claim 5, wherein the at least one projection comprises a pair of spaced apart projections, the connector further comprising a third elastic pushing portion disposed to engage said panel at a location substantially symmetrically between locations on the panel engaged by the projections.

Claim 10

A connector according to claim 8, wherein the first end of the housing defines a substantially continuous peripheral edge, said elastic portion being disposed between said continuous peripheral edge and said jaw portion.

Claim 11

A connector for mounting to a panel, said panel having opposed first and second panel surfaces defining a panel thickness and a mount hole extending through said panel from said first panel surface to said second panel surface, said mount hole having a specified size and shape, said connector comprising: a housing having opposite first and second ends and a plurality of housing walls extending between said first and second ends, portions of said walls adjacent said first end defining a substantially continuous edge extending around said housing, at least one jaw portion projecting outwardly from said side walls of said housing at a location spaced from said first end, said jaw portion defining a cross-section larger than said mount hole, said walls of said housing defining a plurality of outer surfaces between said first end and said jaw portion, said outer surfaces defining a cross-section smaller than the mount hole for permitting portions of said housing between said jaw portion and said first end to be inserted into said mount hole, at least one projection extending from at least one of said outer surfaces at a location between said jaw portion and said first end of said connector housing to define a first lock groove with a maximum width not less than the panel thickness, an elastic portion formed on said housing at a location spaced from said first and second ends, said elastic portion having a projected portion between said first end of said connector housing and said jaw portion to define a second lock groove with a maximum width not less than the panel thickness, said elastic portion being deflectable inwardly to a position where the projected portion lies within the cross-section defined by the outer surfaces, at least first and second elastic pushing portions formed on said jaw portion and projecting obliquely inwardly toward at least one of said outer surfaces of said housing and respectively into said first and second lock grooves, said elastic pushing portions, in unbiased conditions, defining an effective groove width that is less than the panel thickness and being sufficiently deflectable toward said jaw portion to define an actual groove thickness substantially equal to the panel thickness, whereby said elastic pushing portions enable secure gripping of said connector to said panel at said mount hole.

Claim 12

A connector for mounting to a panel, said panel having opposed first and second panel surfaces defining a panel thickness and a mount hole extending through said panel from said first panel surface to said second panel surface, said mount hole having a specified size and shape, said connector comprising: a housing having opposite first and second ends and a plurality of housing walls extending between said first and second ends, portions of said walls adjacent said first end defining a substantially continuous edge extending around said housing, at least one jaw portion projecting outwardly from said side walls of said housing at a location spaced from said first end, said jaw portion defining a cross-section larger than said mount hole, said walls of said housing defining a plurality of outer surfaces between said first end and said jaw portion, said outer surfaces defining a cross-section smaller than the mount hole for permitting portions of said housing between said jaw portion and said first end to be inserted into said mount hole, at least one projection extending from at least one of said outer surfaces at a location between said jaw portion and said first end of said connector housing to define a first lock groove with a maximum width not less than the panel thickness, an elastic portion formed on said housing at a location spaced from said first and second ends, said elastic portion having a projected portion between said first end of said connector housing and said jaw portion to define a second lock groove with a maximum width not less than the panel thickness, said elastic portion being deflectable inwardly to a position where the projected portion lies within the cross-section defined by the outer surfaces, at least first and second elastic pushing portions formed on said jaw portion and projecting obliquely inwardly toward at least one of said outer surfaces of said housing and respectively into said first and second lock grooves, said elastic pushing portions, in unbiased conditions, defining an effective groove width that is less than the panel thickness and being sufficiently deflectable toward said jaw portion to define an actual groove thickness substantially equal to the panel thickness, whereby said elastic pushing portions enable secure gripping of said connector to said panel at said mount hole.

Claim 13

A connector according to claim 10, wherein said first elastic pushing portion is disposed to engage said panel at a location in proximity to said at least one projection, said first elastic pushing portion having a free end, said projection projecting from said outer surfaces further than the free end of the first elastic pushing portion.

Claim 14

A connector according to claim 10, further comprising a third elastic pushing portion, said second and third elastic pushing portions being disposed respectively on opposite sides of said elastic portion.

Claim 15

A connector according to claim 12, wherein the elastic pushing portion has a free end, the projected portion of the elastic portion projecting from the outer surfaces of the housing beyond the free end of the elastic pushing portion.
