Power adapter

Abstract

A power adapter includes a body and a plug. The body includes a top plate and a first side plate, a second side plate, and a third side plate sequentially disposed on the top plate. The first side plate, the second side plate, the third side plate, and the top plate form an accommodating space. The first side plate has a top wall extending into the accommodating space. The top wall, the first side plate, and the top plate form a groove. The plug includes a base, a cover, and a first resilient arm. The cover is detachably assembled to the base and is made of a first material. The first resilient arm is made of a second material and has a fixed end and a free end. The fixed end is connected to the base. The free end has a protrusion. The first resilient arm is configured to slide into the groove so that the plug is located within the accommodating space, and the protrusion is located on the side of the first side plate away from the second side plate. The mechanical strength of the second material is greater than that of the first material.

Claims

1. A power adapter, comprising: a body including a top plate and a first side plate, a second side plate and a third side plate sequentially disposed on the top plate, wherein the first side plate, the second side plate, the third side plate and the top plate form an accommodating space, the first side plate having a top wall extending into the accommodating space, and the top wall, the first side plate and the top plate forming a groove; and a plug including: a base; a cover detachably assembled on the base and made of a first material; and a first elastic arm made of a second material and having a fixed end and a free end, wherein the fixed end is connected to the base, the free end having a protrusion, the first elastic arm being configured to slide into the groove so that the plug is located within the accommodating space and the protrusion is located on the side of the first side plate away from the second side plate, wherein the mechanical strength of the second material is greater than the mechanical strength of the first material.

2. The power adapter as claimed in claim 1, wherein a distance between the free end of the first resilient arm and the base is greater than a distance between the fixed end of the first resilient arm and the base.

3. The power adapter as claimed in claim 1 further includes a locking member and a locking slot, wherein the locking member is disposed on one of the first side plate and the first elastic arm, the locking slot is disposed on the other of the first side plate and the first elastic arm, and the locking member is configured to engage with the locking slot.

4. The power adapter as claimed in claim 1, wherein the plug further includes a conductive element, wherein one of the base and the cover has a chamber, and the conductive element is disposed in the chamber.

5. The power adapter as claimed in claim 4, wherein the conductive element comprises a substrate, a first U-shaped element, a second U-shaped element, a third U-shaped element and a fourth U-shaped element, the first U-shaped element and the second U-shaped element extending from two opposite sides of the substrate and bent toward each other in a first direction, the third U-shaped element and the fourth U-shaped element extending from the two opposite sides of the substrate and bent toward each other in a second direction, the first direction being substantially perpendicular to the second direction.

6. The power adapter as claimed in claim 5, wherein the body includes an inner pin disposed on the second side plate, the side wall of the chamber facing the second side plate has an opening, the inner pin is configured to enter the chamber through the opening, and the first U-shaped member and the second U-shaped member are configured to hold the inner pin.

7. The power adapter as claimed in claim 5, wherein the plug further includes an external pin inserted into the cover and partially located within the cavity, and the third U-shaped member and the fourth U-shaped member are configured to hold the external pin.

8. The power adapter as claimed in claim 1, wherein the plug further includes a second resilient arm and a connecting portion, the second resilient arm having a fixed end and a free end, the connecting portion connecting the fixed end of the first resilient arm and the fixed end of the second resilient arm and being detachably disposed on the base.

9. The power adapter as claimed in claim 8, wherein the base includes a limiting portion, and the first resilient arm further includes a hook portion that extends from the protrusion toward the base and hooks the limiting portion in a direction from the base toward the first resilient arm.

10. The power adapter as claimed in claim 1, wherein the mechanical strength is rigidity or abrasion resistance.
