Abstract
Abstract A cord bushing including a body portion and a lid portion defining a passage for holding a cord and being fittable into a first aperture in an outer panel of an electrical apparatus, flanges provided at one end of the body portion and lid portion and having outer diameters greater than the first aperture, grooves formed in the body portion and the lid portion adjacent to the flanges for locking the body portion and the lid portion in the outer panel, and a falling-off preventing bar in the form of a rod extending from the flange of the body portion substantially in the same direction as the passage and adapted to be inserted into a second aperture when the body portion and lid portion are fitted into the first aperture, the falling-off preventing bar being provided with a check member which prevents the falling-off preventing bar from being extracted once it passes through the second aperture.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A cord bushing comprising: means including a body portion for defining a passage for holding therein a cord and being fittable into a first aperture in an outer panel of an electrical apparatus; flanges provided at one end of said means for defining a passage and having outer diameters greater than said first aperture, one of said flanges forming a part of said body portion; said means for defining a passage including locking means for locking said means for defining a passage in said outer panel adjacent said flanges; and a falling-off preventing bar in the form of a rod extending from said one of said flanges substantially in the same direction as said passage and fittable in a second aperture when the body portion is fitted into said first aperture, said falling-off preventing bar including extraction preventing means in the form of a check member for preventing the falling-off preventing bar from being extracted after passing through said second aperture.
Claim 2
Dependent Claim
161 words
A cord bushing comprising: means including a body portion for defining a passage for holding therein a cord and being fittable into a first aperture in an outer panel of an electrical apparatus; flanges provided at one end of said means for defining a passage and having outer diameters greater than said first aperture, one of said flanges forming a part of said body portion; said means for defining a passage including locking means for locking said means for defining a passage in said outer panel adjacent said flanges; and a falling-off preventing bar in the form of a rod extending from said one of said flanges substantially in the same direction as said passage and fittable in a second aperture when the body portion is fitted into said first aperture, said falling-off preventing bar including extraction preventing means in the form of a check member for preventing the falling-off preventing bar from being extracted after passing through said second aperture.
Claim 3
Dependent Claim
29 words
