Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A holder for a modular circuit board comprising a guide element having an elongated body with a plurality of electrical contact clips located therein, a circuit board having a lower edge provided with electrical contact clips engaged with the electrical contact clips of the elongated body, an upstanding tubular element at each opposite end of the elongated body, a metallic insert in each tubular element, the upper ends of the metallic inserts being screw-threaded; a casing fitting over the circuit board and the tubular elements and having a top, side and end walls; said top wall having captive screw-threaded elements engaging with the screw-threaded upper ends of the inserts detachably to secure the casing to the guide element, means detachably securing the circuit board to the casing, and a second side wall detachably secured to the casing whereby the circuit board is completely enclosed within said casing and the guide element.
Claim 2
Dependent Claim
151 words
A holder for a modular circuit board comprising a guide element having an elongated body with a plurality of electrical contact clips located therein, a circuit board having a lower edge provided with electrical contact clips engaged with the electrical contact clips of the elongated body, an upstanding tubular element at each opposite end of the elongated body, a metallic insert in each tubular element, the upper ends of the metallic inserts being screw-threaded; a casing fitting over the circuit board and the tubular elements and having a top, side and end walls; said top wall having captive screw-threaded elements engaging with the screw-threaded upper ends of the inserts detachably to secure the casing to the guide element, means detachably securing the circuit board to the casing, and a second side wall detachably secured to the casing whereby the circuit board is completely enclosed within said casing and the guide element.
Claim 3
Dependent Claim
46 words
A holder as claimed in claim 1 and including a chassis board extending beneath the guide element, said metallic inserts having screw-threaded lower ends, and screw-threaded elements cooperating with the screw-threaded lower ends of the metallic inserts to secure the guide element to the chassis board.
Claim 4
Dependent Claim
26 words
A holder as claimed in claim 3 in which said tubular elements having opposing guideways formed thereon to receive marginal side edges of the circUit board.
Claim 5
Dependent Claim
18 words
A holder as claimed in claim 4 in which said inserts are non-rotatably received in the tubular elements.
Claim 6
Dependent Claim
216 words
A holder for a modular circuit board comprising a guide element having an elongated body with a plurality of electrical contact clips located therein, a circuit board having a lower edge provided with electrical contact clips engaged with the electrical contact clips of the elongated body, an upstanding tubular element at each opposite end of the elongated body, said tubular elements having opposing guideways formed thereon to receiving marginal side edges of the circuit board, a metallic insert non-rotatably mounted in each tubular element, the upper and lower ends of the metallic inserts being screw-threaded; a casing fitting over the circuit board and the tubular elements and having top, side and end walls; said top wall having captive screw-threaded elements engaging with the screw-threaded upper ends of the inserts detachably to secure the casing to the guide element, means detachably securing the circuit board to the side wall of the casing with the marginal edges of said board entered into the guideways, a second side wall detachably secured to the casing whereby the circuit board is completely enclosed within said casing and the guide element, and a chassis board extending beneath the guide element, and screw-threaded elements co-operating with the screw-threaded lower ends of the metallic inserts to secure the guide element to the chassis board.
