Abstract
Abstract A straddle connector avoids scraping off the solder from the conductive pads by the connection sections of electrical contacts during the connection of the connector to a circuit board. The straddle connector 10 comprises a housing 20 having an opening 21, and a separator 30 which is pushed by an edge 52 of the circuit board 50 when the latter is inserted in the opening 21. Connection sections 41 of the contacts 40 arranged in two rows along the inner walls of the opening 21 of the housing 20 are in contact with cam surfaces 31, 32 of the separator 30 which establishes a gap between opposing connection sections 41 during the insertion of the circuit board 50. After the insertion is completed, the gap between the connection sections 41 becomes smaller than the thickness of the circuit board 50, and the connection sections are applied to the solder-coated conductive pads 51 located on the surfaces of the circuit board at an appropriate pressure without scrapping solder from the conductive pads 51. Therefore, highly reliable SMT soldered connections are obtained when the solder is heated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A straddle connector for connection to solder-coated conductive pads on both surfaces of a circuit board when inserted into the connector, comprising: an insulated housing having an opening; rows of electrical contacts secured in said housing and having connection sections extending along opposed walls of said opening; a dielectric separator disposed in said opening between said connection sections maintaining said connection sections in a biased condition and spaced apart a distance greater than the thickness of the circuit board; and guide means on the housing within said opening and on said separator for guiding said separator into said opening upon engagement of the circuit board with the separator when the circuit board is inserted into said opening between the connection sections so that when the separator is moved free of the connection sections under the insertion force of the circuit board into the opening, the connection sections engage the solder-coated conductive pads on both surfaces of said circuit board for solder connections thereto.
Claim 2
Dependent Claim
163 words
A straddle connector for connection to solder-coated conductive pads on both surfaces of a circuit board when inserted into the connector, comprising: an insulated housing having an opening; rows of electrical contacts secured in said housing and having connection sections extending along opposed walls of said opening; a dielectric separator disposed in said opening between said connection sections maintaining said connection sections in a biased condition and spaced apart a distance greater than the thickness of the circuit board; and guide means on the housing within said opening and on said separator for guiding said separator into said opening upon engagement of the circuit board with the separator when the circuit board is inserted into said opening between the connection sections so that when the separator is moved free of the connection sections under the insertion force of the circuit board into the opening, the connection sections engage the solder-coated conductive pads on both surfaces of said circuit board for solder connections thereto.
Claim 3
Dependent Claim
35 words
A straddle connector as claimed in claim 1, wherein the guide means comprise guide channels in side walls of said opening and wedge-shaped members on the ends of said separator disposed in said guide channels.
Claim 4
Dependent Claim
34 words
A straddle connector as claimed in claim 2, wherein said wedge-shaped members include a flat surface and resilient levers mounted onto said housing engage said flat surface thereby maintaining said separator within said opening.
Claim 5
Dependent Claim
16 words
A straddle connector as claimed in claim 1, wherein said connection sections have outwardly-directed front ends.
Claim 6
Dependent Claim
142 words
An electrical connector for connection to solder-coated conductive pads on a surface of a circuit board when inserted into the connector; comprising: an insulated housing having an opening; electrical contacts secured in said housing and having connection sections extending along a wall of said opening; a dielectric separator disposed in said opening engaging said connection sections thereby maintaining said connection sections in a biased condition; and guide means on the housing within the opening and on said separator for guiding said separator into said opening upon engagement of the circuit board with said separator when the circuit board is inserted into said opening so that said separator is moved free of said connection sections under the insertion force of the circuit board into said opening whereby the connection sections engage the solder-coated conductive pads on said circuit board for solder connections thereto.
Claim 7
Dependent Claim
142 words
An electrical connector for connection to solder-coated conductive pads on a surface of a circuit board when inserted into the connector; comprising: an insulated housing having an opening; electrical contacts secured in said housing and having connection sections extending along a wall of said opening; a dielectric separator disposed in said opening engaging said connection sections thereby maintaining said connection sections in a biased condition; and guide means on the housing within the opening and on said separator for guiding said separator into said opening upon engagement of the circuit board with said separator when the circuit board is inserted into said opening so that said separator is moved free of said connection sections under the insertion force of the circuit board into said opening whereby the connection sections engage the solder-coated conductive pads on said circuit board for solder connections thereto.
Claim 8
Dependent Claim
51 words
An electrical connector as claimed in claim 5 wherein other electrical contacts are secured in said housing and having other connection sections extending along another wall of said opening so that said connection sections are opposed and spaced from each other whereby said separator is positioned between the opposed connection sections.
Claim 9
Dependent Claim
35 words
An electrical connector as claimed in claim 5, wherein said guide means comprise guide channels in side walls of said opening and wedge-shaped members at the ends of said separator disposed in said guide channels.
