A watchband connection mechanism includes a watchband with a watchband housing and a cam rotatable between a first position where the cam extends from the watchband into a watch ledge in a watch side cavity and a second position where the cam is recessed in the watchband housing. A watch includes a watch housing, a watch cavity in the watch housing for receiving at least a portion of the watchband, and a button coupled to the watch housing and movable with respect to the watch cavity. In operation, the watchband is received in the watch cavity of the watch housing, which enables the cam to rotate into the first position to extend from the band into the watch ledge. The watch housing prevents the watchband from uncoupling with the watch in the first position of the cam due to the cam securing in the watch ledge. The user then depresses the button to move the cam into the second position, which is back within the watchband, to uncouple the watchband from the watch.

The present disclosure may provide a connector, an electronic apparatus, a wearable apparatus and an assembly method. The connector may include: a main body and a mating member connected to the main body. An inclined face may be provided on one end of the mating member away from the main body, and a recess may be defined between the inclined face and the main body. The mating member may be configured to be inserted into a mating site of the electronic apparatus; the inclined face may be configured to push an engaging member of the electronic apparatus to move on the inclined face while the mating member is being inserted into the mating site; when the mating member is inserted into the mating site and arrives at a predefined location, the engaging member may be restored and accommodated in the recess to engage with the connector.

A case middle/horn connection device for a watch, a method for attaching an attachment piece including at least one horn to a case middle and a case middle/horn assembly. The connection device includes an attachment piece including at least one horn having a first connector and a case middle having a second connector, the first connector being configured to cooperate with the second connector to attach the attachment piece to the case middle. The first connector includes a tongue with a recess. The second connector includes a groove with an undercut portion. The undercut portion is configured to lodge inside the recess of the tongue; and the case middle and the attachment are made integral when the undercut portion of the second connector is lodged in the recess of the tongue of the first connector.

A wearable device is provided. The wearable device includes a housing. The housing includes a housing base, a housing hook extending from the housing base, and a locking pin extending from the housing base. The wearable device also includes a cover. The cover includes a cover base having an opening to receive the locking pin and a cover hook extending from the cover base. The cover hook is configured to engage the housing hook for latching the cover onto the housing. The wearable device also includes a strap. The strap includes a connector that has a through hole to receive the locking pin securing the strap to the housing and the cover when the housing and the cover are latched.

A connection assembly includes: a support member including a support body and an accommodating groove in the support body; a first clamping member including a fixing part and a first clamping part, the fixing part and the support member being buckled to form an accommodating space with the accommodating groove, the accommodating space having an opening, and the first clamping part is detachably clamped to a first clamping groove in a to-be-connected body by an external force; a second clamping member including a second clamping part which is at least partially in the accommodating space and can be extended or retracted from the opening of the accommodating space to be clamped into or separated from a second clamping groove in the to-be-connected body; and a clamping face of the first clamping part and a clamping face of the second clamping part that are in different planes.

Attachment systems for attaching a wearable electronic device to a user including a sizing band and a retaining band are disclosed. The sizing band includes at least one sizing eyelet and a band-insertable end. The retaining band includes at least a post for insertion into the sizing eyelet of the sizing band and a concealment aperture configured to receive the band-insertable end of the sizing band. On a bottom surface of the retaining band can be a recessed guide bed configured to guide the band-insertable end along the bottom surface of the retaining band. A wearable electronic device can couple to both the sizing band and the retaining band by accepting an end portion of each band into receiving channels extending into opposite sidewalls of the housing.
