Circuit board connector and a board using the same

Claim 2

A circuit board connector comprising: a block member for supporting a plurality of connector pins aligned in a row, the block being made of flexible material; curving portions of the block extending outwardly from a side face of the block member; and grooves formed by cutting the block member from an opposite side face to extend into the curving portion, each groove extending between a different pair of said connector pins along said row.

Claim 3

A circuit board connector in which a plurality of connector pins are arranged in its longitudinal direction and inserted into holes of circuit patterns in a circuit board for a subsequent soldering, said connector comprising: a plurality of independent connector holding portions (20, 20) for holding the plurality of connector pins in a row; and a plurality of connecting portions (4, 4) for resiliently connecting between the plurality of connector holding portions, wherein each connector holding portion and each connecting portion is made of a resin material having resilience, and each connecting portion extends from an outer surface of one of the connector holding portions at one end of the connecting portion to an outer surface of an adjacent one of the connector holding portions at the other end of the connecting portion to form a curved shape having a flexible portion between the one and the adjacent one of the connector holding portions, so that when the connector pins are inserted in the connector holding portions and then into holes of the circuit patterns in the circuit board, stress caused by heat upon soldering of the circuit patterns and the connector pins is absorbed by resilient deformation of the connecting portions having the flexible portions.

Claim 4

A circuit board connector in which a plurality of connector pins are arranged in its longitudinal direction and inserted into holes of circuit patterns in a circuit board for a subsequent soldering, said connector comprising: a plurality of independent connector holding portions (20, 20) for holding the plurality of connector pins in a row; and a plurality of connecting portions (4, 4) for resiliently connecting between the plurality of connector holding portions, wherein each connector holding portion and each connecting portion is made of a resin material having resilience, and each connecting portion extends from an outer surface of one of the connector holding portions at one end of the connecting portion to an outer surface of an adjacent one of the connector holding portions at the other end of the connecting portion to form a curved shape having a flexible portion between the one and the adjacent one of the connector holding portions, so that when the connector pins are inserted in the connector holding portions and then into holes of the circuit patterns in the circuit board, stress caused by heat upon soldering of the circuit patterns and the connector pins is absorbed by resilient deformation of the connecting portions having the flexible portions.

Claim 5

A connector according to claim 2, wherein the connecting portions extend from the same positions relative to an arrangement direction of the connector holding portions.

Claim 6

A connector according to claim 2, wherein the one end of one connecting portion connecting one of the connector holding portions and the other end of an adjacent connecting portion connecting the one connector holding portion are positioned in alternate positions relative to an arrangement direction of the connector holding portions.

Claim 7

A connector according to claim 2, wherein two of the connecting portions extend from opposite positions in the outer surface of one of the connector holding portions, and the curved shape formed by the two connecting portions is substantial symmetrical.

Claim 8

A circuit board connector in which a plurality of connector pins are arranged in its longitudinal direction and inserted into holes of circuit patterns in a circuit board for a subsequent soldering, said connector comprising: a connector block (2) for holding the plurality of connector pins extending in a row, said connector block being made of a resin including a resilient material; the plurality of connector pins being inserted into the connector block (2) at a predetermined distance; groove portions (3, 3) formed in the connector block between each of the connector pins from opposite side faces thereof alternatively; a depth (A1, A2) of each groove from the side face from which it extends being set more than a distance (B1, B2) from that side face to each connector pin; wherein when the connector pin is inserted into each connector holding portion and then into the hole of the circuit patterns in the circuit board, stress caused by heat upon soldering of the circuit pattern and the connector pin is absorbed by movement of pivoting around the bottom portion (2a) of the groove (3).

Claim 9

A circuit board connector in which a plurality of connector pins are arranged in its longitudinal direction and inserted into holes of circuit patterns in a circuit board for a subsequent soldering, said connector comprising: a connector block (2) for holding the plurality of connector pins extending in a row, said connector block being made of a resin including a resilient material; the plurality of connector pins being inserted into the connector block (2) at a predetermined distance; groove portions (3, 3) formed in the connector block between each of the connector pins from opposite side faces thereof alternatively; a depth (A1, A2) of each groove from the side face from which it extends being set more than a distance (B1, B2) from that side face to each connector pin; wherein when the connector pin is inserted into each connector holding portion and then into the hole of the circuit patterns in the circuit board, stress caused by heat upon soldering of the circuit pattern and the connector pin is absorbed by movement of pivoting around the bottom portion (2a) of the groove (3).
