  However, in Patent Document 1, since the screw hole 107 provided in the protruding piece 105 is a long hole that is long in the width direction of the connector housing 104, the moving direction is only the width direction of the connector housing 104. Therefore, since the connector housing 104 can be moved only in one direction after the circuit board connecting portion 102 of the connector terminal 103 is connected to the circuit board by soldering or the like, the connector housing 104 is moved in the other direction. When the necessity arises, there is a possibility that not only a load is applied to the circuit board connection 102 of the connector terminal 103 connected to the circuit board, but a crack or the like may occur in the soldered portion.

As a result, the connector terminal connected to the circuit board is not subjected to a load when the base plate is fixed to the circuit board. Is done. Therefore, reliable joining can be performed without applying a load to the soldered portion.

  2) Further, the connector structure according to the present invention is the connector structure according to (1), wherein the circuit board positioning means of the base plate is a boss inserted into a boss hole provided in the circuit board, The boss is used for positioning and fixing.

  According to the invention described in the above 2), the base plate is simpler than that provided with screw holes or the like because the boss is inserted into the boss hole of the circuit board and positioned on the circuit board. Workability can be improved by performing the assembly work. If the boss of the base plate is inserted into the boss hole of the circuit board and then fixed with fixing means such as a screw, the positioning and fixing can be performed.
