Abstract A new type connector set is provided. Its male connector member includes a male housing having an engaging portion in the form of a nut. The female connector member includes a female housing with an opening to receive said male housing therethrough, a support member fixed within said female housing and having a chamber to receive the engaging portion of the male housing in it and a bolt rotatably extending within said chamber to be screwed into the nut. Said bolt is prevented from moving in an axial direction thereof and has a constricted portion in it.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
A screw type connector set comprising: a first connector member including a first housing, said first housing having an engaging portion in the form of a nut; and a second connector member including a second housing, a support member fixed within said second housing and having a chamber to receive said engaging portion of the first housing therein, and a bolt rotatably extending within said chamber to be screwed into the nut, said bolt having a tapered stepped portion therein, and a stop member engaging said tapered stepped portion to prevent axial movement of said bolt relative to said second connector; and said bolt having a constricted portion therein weaker than said connector members, whereby excessive torison applied to tightening said bolt will cause it to break at said restricted portion and permit disassembly of said first and second connectors.
Claim 2
Dependent Claim
140 words
A screw type connector set comprising: a first connector member including a first housing, said first housing having an engaging portion in the form of a nut; and a second connector member including a second housing, a support member fixed within said second housing and having a chamber to receive said engaging portion of the first housing therein, and a bolt rotatably extending within said chamber to be screwed into the nut, said bolt having a tapered stepped portion therein, and a stop member engaging said tapered stepped portion to prevent axial movement of said bolt relative to said second connector; and said bolt having a constricted portion therein weaker than said connector members, whereby excessive torison applied to tightening said bolt will cause it to break at said restricted portion and permit disassembly of said first and second connectors.
Claim 3
Dependent Claim
20 words
A screw type connector set according to claim 1, wherein said bolt includes a threaded portion and a support portion.
Claim 4
Dependent Claim
44 words
A screw type connector set according to claim 2, wherein said chamber in the support member includes a large diameter section to receive the engaging portion of the first housing and a small diameter section to snugly receive said support portion of the bolt.
Claim 5
Dependent Claim
19 words
A screw type connector set according to claim 3, wherein said constricted portion is formed in said support section.
Claim 6
Dependent Claim
31 words
A screw type connector set according to claim 1, wherein said first housing and said second housing have retention means for temporarily retaining each other to align said bolt and nut.
Claim 7
Dependent Claim
70 words
A screw type connector set according to claim 5, wherein said retention means includes at least one projection provided in an outer surface of said first housing, a slot formed in an inner surface thereof to extend parallel with said bolt and a tapered guide portion formed in an inner rim of said first housing to guide said at least one projection into said slot at the time of engagement.
Claim 8
Dependent Claim
39 words
A screw type connnector set according to claim 1, wherein said engaging portion of the first housing has an irregular shape and said second housing carring a member having a substantially identical shape and orientation to said engaging portion.
Claim 9
Dependent Claim
169 words
A screw type connector set comprising a first connector member including a first housing, said housing having an engaging portion in the form of a nut; and a second connector member including a second housing with an opening to receive said first housing therethrough, support member fixed within said second housing and having a chamber therein to receive said engaging portion of the first housing, and a bolt extending within said chamber to be screwed into the nut, said first housing and said second housing having retention means for temporarily retaining each other to align said bolt and nut, said second connector member having a stop means engagable with a portion of said bolt having a tapered-stepped portion to prevent axial movement of said bolt relative to said second connector, and said bolt having a portion with a constricted diameter weaker than said connecting members, whereby excessive torison applied to tightening said bolt will cause it to break at said restricted portion and allow disassembly of said connector members.
Claim 10
Dependent Claim
169 words
A screw type connector set comprising a first connector member including a first housing, said housing having an engaging portion in the form of a nut; and a second connector member including a second housing with an opening to receive said first housing therethrough, support member fixed within said second housing and having a chamber therein to receive said engaging portion of the first housing, and a bolt extending within said chamber to be screwed into the nut, said first housing and said second housing having retention means for temporarily retaining each other to align said bolt and nut, said second connector member having a stop means engagable with a portion of said bolt having a tapered-stepped portion to prevent axial movement of said bolt relative to said second connector, and said bolt having a portion with a constricted diameter weaker than said connecting members, whereby excessive torison applied to tightening said bolt will cause it to break at said restricted portion and allow disassembly of said connector members.
Claim 11
Dependent Claim
69 words
A screw type connector set according to claim 8, wherein said retention means includes at least one projection provided in an outer surface of said first housing, a slot formed in an inner surface thereof to extend parallel with said bolt and a guide groove formed in an inner rim of said first housing to guide said at least one projection into said slot at the time of engagement.
Claim 12
Dependent Claim
