Watertight welding methods and components
First Claim
1. A method of forming a watertight enclosure for electronic components, comprising:
- providing a first component portion comprising a first groove and a protruding ridge located therein, the first groove including a floor, an inside ridge, and an outside ridge, the inside ridge and the outside each extending from the floor and separated from each other in a first direction, whereinthe protruding ridge comprises a bonding material,the first groove comprises a second groove inside the first groove, andthe second groove and the protruding ridge comprising the bonding material are spaced apart in the first direction;
providing a second component portion comprising a tenon, the tenon shaped to follow a profile of the first groove;
disposing the tenon inside the first groove, such that the tenon contacts the protruding ridge;
applying energy from a power source near the first groove to cause the protruding ridge to melt; and
applying a force to the first component portion relative to the second component portion, such thata portion of the protruding ridge is disposed in a bonding seam formed between an outside surface of the tenon and an inside surface of the first groove,the first component portion and the second component portion are brought together to form the enclosure that is configured to allow one or more electronic components to be disposed therein,a space defined by the second groove is positioned so that the tenon is not disposed within the defined space when the first component portion and the second component portion are brought together to form the enclosure, andat least a portion of excess bonding material flows inside the second groove when the first component portion and the second component portion are brought together to form the enclosure.

Abstract
A method for watertight welding, and components formed using that welding method, wherein the welding method includes providing a first component half with a groove and a protruding ridge located therein, providing a second component half with a tenon shaped to match the profile of the groove, disposing the tenon inside the groove such that the tenon contacts the protruding ridge, applying an ultrasonic power source near the groove to melt the protruding ridge, and applying opposing vertical force to the first component half relative to the second component half, such that the protruding ridge wedges in a bonding seam between an outside surface of the tenon and an inside surface of the groove.

9. A method for bonding a first component portion to a second component portion to form an enclosure for electronic components comprising:
-
providing one or more electronic components; forming a first groove located on a first outer edge of the first component portion, the first groove including a floor, an inside ridge, and an outside ridge, the inside ridge and the outside each extending from the floor and separated from each other in a first direction; forming a protruding ridge located in the first groove, the protruding ridge comprising a bonding material, wherein the first groove comprises a second groove inside the first groove and wherein the second groove and the protruding ridge comprising the bonding material are spaced apart in the first direction; forming a tenon located on a first outer edge of the second component portion, the tenon shaped to follow a profile of the first groove; aligning the first outer edge of the first component portion to the first outer edge of the second component portion, the aligning comprising bringing a first outside lateral edge of the tenon in contact with a first inside lateral edge of the first groove such that the tenon slides inside the first groove and contacts the protruding ridge; maintaining contact between the first outside lateral edge of the tenon and the first inside lateral edge of the first groove while sliding the first component portion towards the second component portion; deforming the protruding ridge by compressing the protruding ridge against the tenon as the first component portion and the second component portion are brought together to form the enclosure for the one or more electronic components, wherein a space defined by the second groove is positioned so that the tenon is not disposed within the defined space when the first component portion and the second component portion are brought together to form the enclosure, and excess bonding material flows inside the second groove when the first component portion and the second component portion are brought together to form the enclosure; applying energy from a power source to each of the tenon, the protruding ridge, and the first groove, such that the bonding material begins to transition to a liquid state and flow into a seam formed between the tenon and the first groove; and cooling the bonding material, such that the bonding material transitions back to a solid state sealing the first component portion to the second component portion that forms the enclosure with the one or more electronic components disposed therein.
