Abstract

A connector includes a garment-side connector portion and a module-side connector portion, the garment-side connector portion has a garment-side connector body with a first fitting surface and a lateral wall, first contacts and a locking portion disposed on the first fitting surface, the module-side connector portion has a module-side connector body with a second fitting surface and a lateral surface, second contacts and a portion to be locked disposed in the second fitting surface, an elastically deformable first waterproof member is disposed on one of the lateral wall of the garment-side connector body and the lateral surface of the module-side connector body so as to surround the first fitting surface or the second fitting surface, and the locking portion locks a position of the portion to be locked only when the module-side connector body is fitted with the garment-side connector body in a predetermined orientation.

First claim

What is claimed is:

1. A connector for mounting a module of a wearable device on a garment to establish electrical connection therebetween, the connector comprising:
a garment-side connector portion to be attached to the garment; and
a module-side connector portion to be fitted to the garment-side connector portion,
wherein the garment-side connector portion includes a garment-side connector body having a first fitting surface and a lateral wall surrounding the first fitting surface, one or more first contacts disposed on the first fitting surface of the garment-side connector body, and a locking portion disposed on the first fitting surface of the garment-side connector body,
wherein the module-side connector portion includes a module-side connector body having a second fitting surface that, when the module-side connector portion is fitted with the garment-side connector portion, faces the first fitting surface and also having a lateral surface surrounding the second fitting surface, one or more second contacts disposed in the second fitting surface of the module-side connector body, and a portion to be locked disposed on the second fitting surface of the module-side connector body,
wherein a first waterproof member that is elastically deformable is disposed on one of the lateral wall of the garment-side connector body and the lateral surface of the module-side connector body so as to surround the first fitting surface or the second fitting surface,
wherein the locking portion locks a position of the portion to be locked only when the module-side connector body is fitted with the garment-side connector body in a predetermined orientation, and
wherein the one or more first contacts and the one or more second contacts are electrically connected to each other, the module-side connector portion is fitted with the garment-side connector portion, and the first waterproof member is elastically compressed between the lateral wall of the garment-side connector body and the lateral surface of the module-side connector body, whereby water is prevented from entering the first fitting surface and the second fitting surface.

2. The connector according to claim 1 ,
wherein the garment-side connector body includes a module-side connector accommodating portion of recess shape whose bottom surface surrounded by the lateral wall forms the first fitting surface,
wherein the module-side connector body is accommodated in the module-side connector accommodating portion when the module side connector portion is fitted with the garment-side connector portion, and
wherein the locking portion locks the position of the portion to be locked only when the module-side connector body is accommodated in the module-side connector accommodating portion in the predetermined orientation.

3. The connector according to claim 2 ,
wherein the first waterproof member is disposed on the lateral surface of the module-side connector body so as to surround circumference of the module-side connector body.

4. The connector according to claim 1 ,
wherein the garment-side connector body includes:
a first insulating member having a flat plate shape and forming the first fitting surface;
a second insulating member of frame shape attached to the first insulating member and surrounding the first fitting surface; and
a second waterproof member disposed between the first insulating member and the second insulating member so as to surround the first fitting surface to prevent water from entering the first fitting surface through a gap between the first insulating member and the second insulating member.

5. The connector according to claim 4 ,
wherein the first insulating member includes a projection projecting toward the second insulating member,
wherein the one or more first contacts have one or more outside contacting portions and are fixed in the first insulating member such that the one or more outside contacting portions are disposed on a surface of the projection,
wherein the second insulating member includes a projection accommodating portion of recess shape in which the projection is accommodated, and
wherein, by fitting the projection of the first insulating member into the projection accommodating portion of the second insulating member with a conductive sheet disposed on the garment being sandwiched between the first insulating member and the second insulating member, one or more conductive members of the conductive sheet come into contact and are electrically connected with the one or more outside contacting portions of the one or more first contacts.

6. The connector according to claim 1 ,
wherein the lateral surface of the module-side connector body extends along a rounded polygon having rotational symmetry with respect to a symmetry axis extending vertically to the second fitting surface, and
wherein an outer shape of the module-side connector body including the portion to be locked does not have rotational symmetry with respect to the symmetry axis.

7. The connector according to claim 6 ,
wherein the portion to be locked is disposed away from the symmetry axis,
wherein a second abutment surface facing in a direction opposite from a direction in which the second fitting surface faces is formed at one end of the module-side connector body, the one end being opposed to the portion to be locked across the symmetry axis,
wherein a first abutment surface facing in a direction opposite from a direction in which the first fitting surface faces and corresponding to the second abutment surface is formed in the garment-side connector body, and
wherein the second abutment surface abuts on the first abutment surface when the module-side connector portion is accommodated in the module-side connector accommodating portion of the garment-side connector portion.

8. The connector according to claim 7 ,
wherein the module-side connector portion is fitted to the garment-side connector portion by inserting the one end of the module-side connector body into the module-side connector accommodating portion such that the second fitting surface is inclined to the first fitting surface and the second abutment surface abuts on the first abutment surface, and then pushing the other end of the module-side connector body on an opposite side from the one end toward the first fitting surface.

9. The connector according to claim 7 ,
wherein the second abutment surface is positioned closer to the second fitting surface than the first waterproof member is.

10. The connector according to claim 7 ,
wherein the module-side connector portion includes a plurality of the second contacts aligned in the second fitting surface along a direction from the one end of the module-side connector body toward the other end thereof, and
wherein the garment-side connector portion includes a plurality of the first contacts aligned on the first fitting surface so as to correspond to the plurality of the second contacts.

11. The connector according to claim 1 ,
wherein each of the one or more first contacts is a contact having no spring properties, and
wherein each of the one or more second contacts is a contact having spring properties.

12. The connector according to claim 11 ,
wherein the module-side connector portion includes a substrate disposed on a side opposite from a side on which the second fitting surface of the module-side connector body is situated, and
wherein each of the one or more second contacts includes: a first contact contacting portion positioned at one end thereof to be contacted with a corresponding one of the one or more first contacts; a substrate contacting portion positioned at the other end thereof and
