Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
A casing for enclosing a circuit board therein, comprising: a pair of symmetrical halves interlocked together, each half forming first and second longitudinal sides opposite to each other, a plurality of clipping tabs formed on said first longitudinal side and a plurality of retaining receptacles defined on said second longitudinal side in a manner such that said clipping tabs on one half are aligned with said retaining receptacles on the other half, while said retaining receptacles on said one half are aligned with said clipping tabs on the other half, a pair of positioning frames respectively attaching to the pair of symmetrical halves, each positioning frame including a first and a second sub-frames, each of the second sub-frames defining a plurality of receptacles aligned with said retaining receptacles on the half of the casing to which it is attached; whereby said clipping tabs and said receptacles of the second sub-frames are interlocked together via the engagement of barbs of said clipping tabs with inner walls of said receptacles of the second sub-frames for facilitating the formation of a complete seal along a perimeter of said one and the other halves when said halves are assembled together.
Claim 2
Dependent Claim
196 words
A casing for enclosing a circuit board therein, comprising: a pair of symmetrical halves interlocked together, each half forming first and second longitudinal sides opposite to each other, a plurality of clipping tabs formed on said first longitudinal side and a plurality of retaining receptacles defined on said second longitudinal side in a manner such that said clipping tabs on one half are aligned with said retaining receptacles on the other half, while said retaining receptacles on said one half are aligned with said clipping tabs on the other half, a pair of positioning frames respectively attaching to the pair of symmetrical halves, each positioning frame including a first and a second sub-frames, each of the second sub-frames defining a plurality of receptacles aligned with said retaining receptacles on the half of the casing to which it is attached; whereby said clipping tabs and said receptacles of the second sub-frames are interlocked together via the engagement of barbs of said clipping tabs with inner walls of said receptacles of the second sub-frames for facilitating the formation of a complete seal along a perimeter of said one and the other halves when said halves are assembled together.
Claim 3
Dependent Claim
19 words
A casing as recited in claim 1, wherein said clipping tab further comprises barbs extending from both sides thereof.
Claim 4
Dependent Claim
257 words
A PC card assembly, comprising: a casing having a pair of symmetrical halves interlocked together, each half forming first and second longitudinal sides opposite to each other, a plurality of clipping tabs formed on said first longitudinal side and a plurality of retaining receptacles defined on said second longitudinal side in a manner such that said clipping tabs on one half are aligned with said retaining receptacles on the other half, while said retaining receptacles on said one half are aligned with said clipping tabs on the other half, each of said longitudinal sides defining a retaining groove; a circuit board suitably enclosed within said casing; and a pair of positioning frames supporting the circuit board within the casing, each of the positioning frame including a first and a second separately molded sub-frames, the first and the second sub-frames being respectively retained in corresponding retaining grooves of the first and second longitudinal sides, respectively, of the pair of halves of the casing, each of the second sub-frames defining a plurality of receptacles aligned with said retaining receptacles on the half of the casing to which it is attached; whereby said clipping tabs of the one and the other halves of the casing are respectively inserted through said retaining receptacles of the other and the one halves of the casing and are fixedly interlocked with inner walls of the receptacles of the second sub-frames for facilitating the formation of a complete seal along a perimeter of said one and the other halves when said halves are assembled together.
Claim 5
Dependent Claim
257 words
A PC card assembly, comprising: a casing having a pair of symmetrical halves interlocked together, each half forming first and second longitudinal sides opposite to each other, a plurality of clipping tabs formed on said first longitudinal side and a plurality of retaining receptacles defined on said second longitudinal side in a manner such that said clipping tabs on one half are aligned with said retaining receptacles on the other half, while said retaining receptacles on said one half are aligned with said clipping tabs on the other half, each of said longitudinal sides defining a retaining groove; a circuit board suitably enclosed within said casing; and a pair of positioning frames supporting the circuit board within the casing, each of the positioning frame including a first and a second separately molded sub-frames, the first and the second sub-frames being respectively retained in corresponding retaining grooves of the first and second longitudinal sides, respectively, of the pair of halves of the casing, each of the second sub-frames defining a plurality of receptacles aligned with said retaining receptacles on the half of the casing to which it is attached; whereby said clipping tabs of the one and the other halves of the casing are respectively inserted through said retaining receptacles of the other and the one halves of the casing and are fixedly interlocked with inner walls of the receptacles of the second sub-frames for facilitating the formation of a complete seal along a perimeter of said one and the other halves when said halves are assembled together.
Claim 6
Dependent Claim
21 words
An assembly as recited in claim 3, further comprising an insulating layer arranged between said half and said printed circuit board.
