Charger with hub
View Patent ↗A charger includes a charging unit and a hub unit. The charging unit includes an enclosure, a charging circuit and two wires. The enclosure defines a matching groove. Opposite sidewalls of the matching groove separately define a limiting groove. The hub unit includes a foundation, a circuit unit, a locking protrusion, a pair of bolts and a pair of hook assemblies. The foundation defines a holder. The locking protrusion, the bolts and the latching members are all received in the holder. One end of each of the two wires is electrically coupled to the charging circuit, and the other end of each of the two wires extends through the matching groove and the receiving groove in that order and electrically couples to the circuit unit.
1. A charger, comprising:
a charger unit comprising an enclosure and a charging circuit received in the enclosure; the enclosure comprising a first surface, a second surface opposite to the first surface and a sidewall connected with the first surface and the second surface, the first surface defining a fitting groove for fitting an electronic device, wherein a matching groove is defined at a connection of the second surface and the sidewall, and a slot is defined in the matching groove; and
a hub unit comprising a foundation, the foundation comprising a first side, a second side opposite to the first side, and a base side connected with the first side and the second side; and
a circuit unit received in the foundation; and
an antenna coupled to the circuit unit for receiving signals;
wherein a holder for receiving the charger unit is concavely located at a connection of the base side and the second side and comprises a locking protrusion, a bolt located at a side of the locking protrusion and a latching member resting against the bolt, and two wires that are electrically coupled to the charger unit and the hub unit.
2. The charger of claim 1 , wherein the matching groove comprises a floor perpendicular to the first surface, a pair of opposite first sidewalls, a second sidewall connected with the first sidewalls, each of the first sidewalls defines the slot through the sidewall of the enclosure and the floor, and the latching member is latched with the slot.
3. The charger of claim 2 , wherein the floor of the matching groove defines a first through hole, the locking protrusion defines a second through hole perpendicular to the first side, and the two wires extend through the first through hole and the second through hole to electrically couple the charging unit and the circuit unit.
4. The charger of claim 1 , wherein the second side of the foundation defines a jack for connecting to a power source.
5. The charger of claim 1 , wherein the holder comprises a bottom parallel to the first side, a pair of first lateral wall, and the locking protrusion is located at a central section of the bottom and extends toward the first side.
6. The charger of claim 5 , wherein the locking protrusion defines a fixing groove located at a side of the locking protrusion, and the slot is received in the fixing groove.
7. The charger of claim 6 , wherein the fixing groove perpendicularly passes through the bottom and the locking protrusion.
8. The charger of claim 6 , wherein the bottom of the holder defines a fixing hole close to the fixing groove, and the latching member is received in the fixing hole.
9. The charger of claim 8 , wherein the latching member comprises a hook latched with the slot and a limiting portion resting against the bolt.
10. The charger of claim 9 , wherein a side of the limiting portion facing the bolt is arc matching with the bolt.
