Abstract

A golf ball head includes a head unit and an insertion unit. The insertion unit includes a housing body, an intelligent unit and an encapsulant. The housing body is threaded into an installation hole of the head unit, defines a receiving space, and has a base wall, a surrounding wall, an external thread for threadedly engaging the internal thread, and a recess formed in the base wall. The intelligent unit is received in the receiving space, and includes a circuit board, two charging electrodes disposed on the first circuit board, and a capacitor connected to the first circuit board and the charging electrodes. The encapsulant is received in the receiving space and exposes the charging electrodes.

Claims

1. A golf club head comprising:

a head unit including a main body, an installation hole formed in said main body, and an internal thread formed on an inner wall surface of said main body and defining said installation hole; and

an insertion unit including

a housing body that defines a receiving space having an opening, and that has a base wall, a surrounding wall extending from a periphery of said base wall, an external thread formed on an outer surface of said surrounding wall for threadedly engaging said internal thread of said head unit so that said insertion unit is detachably received in said installation hole, and a recess formed in said base wall and adapted to permit a tool to be engaged and rotated therein so as to rotate said housing body relative to said head unit,

an intelligent unit that is received in said receiving space, and that includes a first circuit board disposed in said opening of said receiving space, two charging electrodes disposed on said first circuit board, and a capacitor electrically connected to said first circuit board and said charging electrodes, and

an encapsulant that is received in said receiving space, that at least partially covers said first circuit board of said intelligent unit, and that fixes said intelligent unit in said receiving space, said charging electrodes being exposed from said encapsulant.

2. The golf club head as claimed in claim 1, wherein said insertion unit further includes a holding unit that is received in said receiving space, said intelligent unit extending through and being fixed to said holding unit.

3. The golf club head as claimed in claim 2, wherein said holding unit has a base plate formed with a through hole through which said intelligent unit extends, a plurality of first extending portions extending from said base plate in a direction away from said base wall, and a plurality of second extending portions extending from said base plate in a direction toward said base wall, any two adjacent ones of said first extending portions cooperatively defining a first encapsulant-receiving space therebetween, in which a portion of said encapsulant is filled, any two adjacent ones of said second extending portions cooperatively defining a second encapsulant-receiving space therebetween, in which another portion of said encapsulant is filled, said first extending portions and said base plate cooperatively defining a board-receiving space that receives said first circuit board of said intelligent unit, said second extending portions and said base plate cooperatively defining a capacitor-receiving space (304) that receives said capacitor of said intelligent unit.

4. The golf club head as claimed in claim 1, wherein said base wall of said housing body has a protrusion portion that extends away from said receiving space, said recess being formed in said protrusion portion.

5. The golf club head as claimed in claim 1, wherein said intelligent unit of said insertion unit further includes a second circuit board that is spaced apart from said first circuit board, said capacitor being further electrically connected to said second circuit board.
