A track system may include a track assembly and a support assembly. A track assembly may include a toothed portion. The support assembly may include a support member removable from and adjustably connected to the track assembly. The toothed portion may include a plurality of track teeth. The support member may include an adjuster pinion. The adjuster pinion may include a plurality of pinion teeth configured to engage the plurality of track teeth. The adjuster pinion may be adjustable to an engaged position in which the adjuster pinion and the toothed portion are engaged with one another. The adjuster pinion may be adjustable to a disengaged position in which the adjuster pinion and the toothed portion are not engaged with one another.

A support member may be connectable in a removable and adjustable manner to a track assembly. The support member may include an electrical connector, a contact, and a biasing member. The electrical connector may be adjustable to a first position and a second position. The contact may be connected to the electrical connector and configured to engage a conductor of said track assembly. The contact may be engageable with said conductor when the electrical connector is in the first position. The contact may not be engageable with said conductor when the electrical connector is in the second position. The biasing member may be configured to bias the contact into engagement with said conductor when the electrical connector is in the first position.

A housing (10) is formed with a partial locking stopper (21) and a full locking stopper (24). A slide lever (25) (operating member) is formed with a single hook (33) having a partial locking contact surface (35) and a full locking contact surface (36). The partial locking contact surface (35) is at an acute angle to a sliding direction of the slide lever (25) and restricts a movement of the slide lever (25) at the partial locking position in a direction separating from the housing (10) by contacting the partial locking stopper (21). The full locking contact surface (36) is at an obtuse angle to the sliding direction of the slide lever (25) and restricts a movement of the slide lever (25) at the full locking position toward the partial locking position by contacting the full locking stopper (24) in a semi-locked state.

A lever 50 is arranged movably from a partial locking position before connection of both housings 10, 90 and a full locking position after the connection with respect to the housing 10. Entrances 56 of cam grooves 54, 55 of the lever 50 are open in an edge part of the lever 50. The housing 10 includes a lock piece 31 resiliently displaceable in a direction intersecting a moving direction of the lever 50 to the full locking position. The lock piece 31 includes a lock portion 35 arranged at entrances 56 of the cam grooves 54, 55 and facing inner surfaces of the entrances 56 with the lever 50 located at the partial locking position. The lock portion 35 includes a protruding portion 37 projecting from the entrances 56 of the cam grooves 54, 55.

A connector is provided with a rear seal portion to be arranged to face a rear surface of a housing, and a rear wall portion to be arranged to face a rear surface of the rear seal portion. The housing includes a lock piece projecting rearward from the rear surface and the lock piece includes a lock portion on a tip side. The rear seal portion includes a lock-side seal hole to be held in close contact with a base end side of the lock piece and a sealing surface to be held in close contact with a mating housing on an outer peripheral side. The rear wall portion includes a lock receiving portion to be locked by the lock portion on an inner surface of a through hole. Out of an outer part and an inner part, the lock receiving portion is provided on the inner part.

A first housing 10 includes a resiliently deformable lock arm 30. The lock arm 30 has a lock surface 34 to be arranged to contact a front surface of a panel 90 with the first housing 10 arranged in a mounting hole 91 of the panel 90. A second housing 40 includes a space portion 53 into which an arm plate 72 of a lever 70 is arranged, leg portions 57 rising from the side of an outer wall 52 of the space portion 53 while facing each other, and a bridge portion 58 extending between the leg portions 57 facing each other. The bridge portion 58 includes a releasing portion 65 capable of releasing a state where the lock surface 34 is in contact with the front surface of the panel 90.

A first housing 10 is arranged in a mounting hole 91 of a panel 90. The first housing 10 includes a base portion 27, a coupling portion 28 located forward of the base portion 27, a linking portion 29 linking between the base portion 27 and the coupling portion 28, and a lock arm 30 projecting rearward toward the base portion 27 from the coupling portion 28. The lock arm 30 has a lock surface 34 to be arranged to contact a front surface of the panel 90. The lock arm 30 and the linking portion 29 are both shaped to be resiliently deformable.

A connector system with a primary connector and a coupling connector, and a method for connecting a coupling connector and a primary connector. The system provides an insertion aid for mating the connectors. The connector system has a primary connector with a connecting part and a coupling connector with a base unit and a connecting part. The coupling connector has a slider part that moves relative to the base unit to either a preliminary position or a final position. The connecting part of the coupling connector mates with the connecting part of the primary connector. The slider part and the primary connector each have at least one guiding component which both interact to enforce a predefined motion path of the slider part relative to the primary connector when the coupling connector is coupled with the primary connector and the slider part is moved from the preliminary position to the final position.
