Abstract

There is described a connector assembly having a first connector part and a second connector part. At least one of the first connector part and the second connector part comprises at least one magnet for providing an attractive force between the first connector part and the second connector part to align the first connector part and the second connector part in a connected state. The first connector part comprises a guide track and the second connector part comprises a follower, the guide track being shaped to guide movement of the follower, under the influence of said attractive force, to a retaining position in which the follower engages an abutment surface on the first connector part to provide a retaining mechanism for retaining the first connector part and the second connector part in the connected state.

Claims

1. A connector assembly comprising a first connector part and a second connector part, at least one of the first connector part and the second connector part comprising at least one magnet for providing an attractive force between the first connector part and the second connector part to align the first connector part and the second connector part in a connected state,

wherein the first connector part comprises a guide track and the second connector part comprises a follower, the guide track being shaped to guide movement of the follower, under the influence of said attractive force, to a retaining position in which the follower engages an abutment surface on the first connector part without any deformation or flexing of the first connector part or the second connector part, to provide a retaining mechanism for retaining the first connector part and the second connector part in the connected state.

2. The connector assembly of claim 1, wherein the guide track comprises a lip portion overhanging a portion of a recess in the first connector par, the lip portion having an outer surface and an inner surface facing the recess, and the follower comprises a lug portion, wherein the lip portion and the lug portion are shaped to guide movement of the lug portion, under the influence of said attractive force, around the outer surface of the lip portion and into the recess to provide the retaining mechanism.

3. The connector assembly of claim 2, wherein the lip portion is arranged to guide the lug portion into the recess via a first passage, and wherein the recess further comprises a second passage for egress of debris.

4. The connector assembly of claim 3, wherein the recess is shaped such that a magnetic force associated with said at least one magnet attracts ferrous debris out of the recess via the second passage.

5. The connector assembly of claim 2, the first connector part comprising a first planar connection surface and the second connector part comprising a second planar connection surface,

wherein the first planar connection surface is aligned adjacent to the second planar connection surface in the connected state by said attractive force.

6. The connector assembly of claim 5, wherein the lip portion has a first surface and a second surface interconnected at an edge, the first surface facing away from the first connector part and the second surface facing into the first connector part, the first surface being angled with respect to the first planar connection surface to provide a reaction force on the lug portion of the second connector part having a component in the plane of the first planar connection surface to guide the second connector part to said edge.

7. The connector assembly of claim 6, wherein said attractive force has a component in the plane of the first connection surface to guide the lug portion of the second connector part from the edge in a direction along the second surface of the lip portion.

8. The connector assembly of claim 6, wherein the second surface of the lip portion is substantially parallel to the plane of the first planar connection surface, wherein in the connected state the second surface inhibits movement of the second connector part away from the first connector part in a direction perpendicular to the first planar connection surface.

9. The connector assembly of claim 1, wherein the first connector part comprises two linear lip portions arranged parallel to each other, and wherein the second connector part comprises two linear lug portions arranged parallel to each other and configured to engage respective different ones of the two linear lip portions.

10. The connector assembly of claim 5, wherein the first connector part has a first magnet having a first magnetic axis aligned parallel to the plane of the first planar connection surface and the second connector part has a second magnet having a second magnetic axis aligned parallel to the second planar connection surface,

wherein when the first magnetic axis and the second magnetic axis are aligned in opposite directions the first magnet and the second magnet are attracted to each other and wherein when the first magnetic axis and the second magnetic axis are aligned in the same direction the first magnet and the second magnet are repelled from each other.

11. A textile electrical component comprising a connector part as claimed in claim 1.

12. A textile electrical component as claimed in claim 11, wherein the textile electrical component is wearable.

13. A textile electrical component as claimed in claim 11, wherein the textile electrical component comprises a wire loom.
