Patent attributes
It is aimed to enable a plurality of device-side connectors and a plurality of holding-side connectors to be collectively connected without enlarging the device-side connectors. Device-side connectors (3) are mounted on respective juxtaposed solenoids (1). Holding-side connectors (7) corresponding to these device-side connectors are mounted on a holder (18) via coupling members (19). A guiding groove (8) including a positioning portion (8A) is formed on the solenoid (1), and a guide portion (9) is formed on the coupling member (19) of the holding-side connector (7). The guide portion (9) corrects the posture of the holding-side connector (7) by the positioning portion (8A), whereby the device-side connector (3) and the holding-side connector (7) are guided to be opposed to each other.
