[Means for Solving the Problems]

 The present invention is intended to connect one connector to which a plurality of first electrode members are mounted and the other connector to which a plurality of second electrode members electrically connected to each first electrode member are mounted. In the connector coupling structure, a protrusion is provided on a side surface of each connector, and a positioning member having a through hole for engaging each protrusion is attached to couple the connectors. It is the connecting structure of the connector to be considered.

Further, the present invention is characterized in that an adhesive layer is formed on a surface of the positioning member facing the side surface of each connector.

[0012]

[Action]

 According to the invention, a plurality of first electrode members are attached to one connector and a second electrode member is attached to the other connector. After the first electrode member is electrically connected to the second electrode member, the projection formed on the side surface of each connector is engaged with the through hole formed in the positioning member, thereby positioning the first electrode member. Misalignment is prevented. Thus, the electrical connection between the first electrode member and the second electrode member can be stably ensured with a simple structure in which the positioning member is simply attached, and the positioning member can be easily removed. Therefore, workability is also good when removing the connector.

Further, according to the present invention, since the adhesive layer is formed on the surface of the positioning member facing the side surface of each connector, the connectors are more firmly coupled.
