Abstract
Abstract In a plug and a receptacle of a microstrip line connector, the plug has a rectangular parallelpipedic insulating support block, a signal contact projecting upward from the center of the insulating support block and a pair of L-angle brackets projecting out upward from both ends of the insulating support block, the pair of brackets being connected to opposite ends of a coupling plate portion provided along the side wall surface of the insulating support block. The coupling plate portion has at the center of its lower marginal edge a recess formed astride a signal conductor of a microstrip line provided on a printed circuit board. The receptacle is made up of a rectangular parallelpipedic insulating housing having three contact housing rooms defined by two partition walls, a signal socket contact housed in the central contact housing room, a U-shaped ground socket contact having two contact portions housed in the side contact housing rooms, and a shield cover mounted on the insulating housing in a manner to cover almost all over its back and hold its top and bottom panel portions. The insulating housing has a contact introducing hole in its front panel portion centrally thereof and communicating with the central contact housing room, for receiving the signal contact of the mating plug. The insulating housing has slots in its side panel portions in the front-to-back direction and communicating with the side contact housing rooms, for receiving opposed edges of the pair of L-angle brackets.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A plug of a microstrip line connector comprising: A) a ground contact member including a coupling plate portion disposed astride a signal conductor forming a microstrip line and having a recess formed to avoid its contact with said signal conductor, and a pair of contact piece means projecting out from both ends of said coupling plate portion in a direction substantially perpendicular to the surface of an insulating plate on which said strip line is formed; B) a signal contact member for engaging the microstrip line and including a terminal disposed midway between said pair of contact piece means of said ground contact member, and a signal contact piece bent from said terminal at right angles thereto and extending in parallel to said pair of contact piece means; and C) an insulating support block for supporting said signal contact member and said ground contact member as a unitary structure while insulating them from each other with the ground and signal contact pieces positioned for engagement with terminals of a mating connector.
Claim 2
Dependent Claim
171 words
A plug of a microstrip line connector comprising: A) a ground contact member including a coupling plate portion disposed astride a signal conductor forming a microstrip line and having a recess formed to avoid its contact with said signal conductor, and a pair of contact piece means projecting out from both ends of said coupling plate portion in a direction substantially perpendicular to the surface of an insulating plate on which said strip line is formed; B) a signal contact member for engaging the microstrip line and including a terminal disposed midway between said pair of contact piece means of said ground contact member, and a signal contact piece bent from said terminal at right angles thereto and extending in parallel to said pair of contact piece means; and C) an insulating support block for supporting said signal contact member and said ground contact member as a unitary structure while insulating them from each other with the ground and signal contact pieces positioned for engagement with terminals of a mating connector.
Claim 3
Dependent Claim
139 words
The plug of claim 1 wherein said insulating support block is a substantially rectangular parallelpipedic member, wherein said coupling plate portion of said ground contact member is a plate-like member covering substantially the entire area of one side surface of said insulating support block and holding said insulating support block between its both ends, and wherein said pair of contact piece means is formed by a pair of L-angle brackets including first plate portions coupled together through said coupling plate portion and having faces opposed to each other and second plate portions bent from said first plate portions at right angles thereto toward each other and having their lower end portions received in grooves cut in both sides of said insulating support block, edges of said second plate portions being contacted with a ground contact of the mating plug.
Claim 4
Dependent Claim
45 words
The plug of claim 1 or 2 wherein said coupling plate portion has the central portion of its lower marginal edge removed to form said recess and has its upper marginal portion bent to form a press piece for engagement with said insulating support block.
Claim 5
Dependent Claim
345 words
A receptacle of a microstrip line connector which receives a plug having a pair of contact piece means of a ground contact member and a signal contact disposed midway between said pair of contact piece means and which is mounted on a microstrip printed circuit board, said receptacle comprising: A) a substantially rectangular parallelpipedic insulating housing having formed therein contact housing room means and made up of side panel portions having slots made therein in communication with said contact housing room means for receiving said pair of contact piece means of said ground contact member of said plug, a front panel portion having a contact introducing hole made therein substantially centrally thereof in communication with said contact housing room means, and a top panel portion formed as a unitary structure with said front panel portion and said side panel portions; B) signal socket contact means including contact piece means housed in said contact housing room means of said insulating housing and making elastic contact with said signal contact of said plug on the axis of said contact introducing hole, and an extended piece extended from the base portion of said contact piece means along the inner wall surface of said top panel portion and having a predetermined area; C) ground socket contact means housed in said contact housing room means of said insulating housing and exposed through said slots made in said side panel portions of said insulating housing for contact with said contact piece means of said ground contact member of said plug; and D) a shield cover electrically connected to said ground socket contact means and having at least a top panel portion covering substantially the entire area of the outer wall surface of said top panel portion of said insulating housing and a rear panel portion covering the back of said insulating housing, said shield cover being disposed opposite said extended piece of said signal socket contact means to form an electrostatic capacitance between it and said signal socket contact means and being connected to a ground conductor of a microstrip line.
