A transformer includes a bobbin, an I-bar, the first U-core, and the second U-core. The bobbin in a tube shape is wrapped around by a number of windings of copper coil. An I-bar made of high permeable alloy has a first end and a second end. The I-bar is inserted into the bobbin and the first end and the second end of the I-bar protrude outside the tube of the bobbin respectively. A first U-core made of high permeable alloy is placed on one side of the bobbin and a second U-core made of high permeable alloy is placed on the other side of the bobbin. The two ends of the first U-core and the second U-core connect the I-bar through the films and the sunken parts of the first U-core and the second U-core are in opposition to each other.

A bobbin of a transformer includes a hollow sleeve, a first pin set, a partition, and a second pin set. The hollow sleeve is a hollow polyhedron, and the hollow sleeve is wrapped around by a number of the copper coils. A winding-started point is near the corner of the hollow sleeve. The pin set includes a first pin and a first griding slot, wherein the first pin is for being wrapped around by a starting point of the first copper wire, and the first griding slot is for placing the copper wire segment from the starting point to the winding-started point. The partition is for connecting the hollow sleeve and the first pin set. The corner of the hollow sleeve is an intersection point of a top plane the hollow sleeve, a side plane of the hollow sleeve, and the partition. The transformer bobbin of the invention can prevent the short circuit and raise the yield of the transformer.

A modular power connector includes an insulation main body, at least one conducting element, at least one electricity-delivering element, and at least one engaging element. The conducting element is partially accommodated within the insulation main body, and includes a perforation. The electricity-delivering element has a bare part at an end thereof. The engaging element is fixed on the bare part of the electricity-delivering element, and includes an elastic extension part and a stopping part. The elastic extension part is subject to elastic deformation during the elastic extension part is penetrated through the perforation of the conducting element. The elastic extension part is restored to an original shape after the elastic extension part is penetrated through the perforation, so that the conducting element is clamped between the elastic extension part and the stopping part.
