Abstract
Abstract Disclosed is a circuit board connector in which stress will not be produced in solder even if there is a change in ambient temperature, and in which it is possible to reduce residual stress, which accompanies hardening of the solder, produced by a difference in heat shrinkage between the circuit board and the connector, thereby making it possible to prevent cracking of the solder and peeling off of circuit patterns. The circuit board connector has a plurality of electrical contacts arranged in a row on a connector body, the connector body including a plurality of holding portions for independently holding respective ones of the plurality of electrical contacts, and deformable portions flexibly interconnecting the plurality of holding portions in such a manner that the holding portions are capable of moving relative to one another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
A circuit board connector in which a plurality of electrical contacts are arranged in a row on a connector body, said connector body comprising: a plurality of holding portions for independently holding one of the plurality of electrical contacts; and deformable portions flexibly interconnecting said plurality of holding portions in such a manner that said holding portions are capable of moving relative to one another, wherein said connector body is formed from a synthetic resin and said deformable portions are integrally molded with said plurality of holding portions, and said deformable portions are formed into fan-shaped ribs, each rib having a first end and a second end, the first ends being connected to one another and the second ends being connected to respective ones of said plurality of holding portions.
Claim 2
Dependent Claim
130 words
A circuit board connector in which a plurality of electrical contacts are arranged in a row on a connector body, said connector body comprising: a plurality of holding portions for independently holding one of the plurality of electrical contacts; and deformable portions flexibly interconnecting said plurality of holding portions in such a manner that said holding portions are capable of moving relative to one another, wherein said connector body is formed from a synthetic resin and said deformable portions are integrally molded with said plurality of holding portions, and said deformable portions are formed into fan-shaped ribs, each rib having a first end and a second end, the first ends being connected to one another and the second ends being connected to respective ones of said plurality of holding portions.
Claim 3
Dependent Claim
152 words
A plurality of circuit board connectors, with each circuit board connector having a plurality of electrical contacts arranged in a row on a connector body, said connector body, comprising: a plurality of holding portions for independently holding one of said plurality of electrical contacts; and deformable portions flexibly interconnecting said plurality of holding portions in such a manner that said holding portions are capable of moving relative to one another, wherein said plurality of electrical contacts are a plurality of contact pins forming male connectors, said plurality of connector pins being passed through respective pattern holes of a circuit board while being held by said connector body and being soldered to the circuit board, and wherein each holding portion of one circuit board connector is inserted between mutually adjacent holding portions of another circuit board connector, in which state mating is achieved with a plurality of connector pins on the circuit boards.
Claim 4
Dependent Claim
152 words
A plurality of circuit board connectors, with each circuit board connector having a plurality of electrical contacts arranged in a row on a connector body, said connector body, comprising: a plurality of holding portions for independently holding one of said plurality of electrical contacts; and deformable portions flexibly interconnecting said plurality of holding portions in such a manner that said holding portions are capable of moving relative to one another, wherein said plurality of electrical contacts are a plurality of contact pins forming male connectors, said plurality of connector pins being passed through respective pattern holes of a circuit board while being held by said connector body and being soldered to the circuit board, and wherein each holding portion of one circuit board connector is inserted between mutually adjacent holding portions of another circuit board connector, in which state mating is achieved with a plurality of connector pins on the circuit boards.
Claim 5
Dependent Claim
123 words
A connector connected to a group of electrical contacts arranged in a curved line on a printed circuit board, comprising: a plurality of holding portions to be connected to the electrical contacts; a flexible loop connecting portion having one end connected to a side surface of a first holding portion and the other end connected to a side surface of an adjacent second holding portion; signal transmission cables for receiving from or transmitting to the printed circuit board a predetermined signal via a connecting portion between each holding portion and the respective electrical contact, wherein said plurality of holding portions can be positioned at and connected to the electrical contacts arranged in the curved line due to flexibility in said loop connecting portion.
Claim 6
Dependent Claim
123 words
A connector connected to a group of electrical contacts arranged in a curved line on a printed circuit board, comprising: a plurality of holding portions to be connected to the electrical contacts; a flexible loop connecting portion having one end connected to a side surface of a first holding portion and the other end connected to a side surface of an adjacent second holding portion; signal transmission cables for receiving from or transmitting to the printed circuit board a predetermined signal via a connecting portion between each holding portion and the respective electrical contact, wherein said plurality of holding portions can be positioned at and connected to the electrical contacts arranged in the curved line due to flexibility in said loop connecting portion.
Claim 7
Dependent Claim
164 words
A connector connected to a plurality of electrical contacts continuously arranged on a printed circuit board, with at least some of the electrical contacts being arranged in a straight line, comprising: a plurality of holding portions to be connected to the plurality of electrical contacts; a flexible loop connecting portion having one end connected to a side surface of a first holding portion and the other end connected to a side surface of an adjacent second holding portion, with said loop connecting portion having a first width at both ends and a second width at a middle portion that is smaller than the first width; a plurality of signal transmission cables for receiving from or transmitting to the printed circuit board a predetermined signal via a connecting portion between each holding portion and the respective electrical contact, wherein said plurality of holding portions can be connected to the electrical contacts arranged on the printed circuit board due to flexibility in said loop connecting portion.
