The invention discloses an electric connector. The electric connector comprises an insulation body and a plurality of conductive terminals. The insulation body comprises a base portion and a tongue plate extending forwards from the base portion. The conductive terminals include a row of upper terminals and a row of lower terminals. Each upper terminal comprises an upper fixing portion embedded into the insulation body, an upper contact portion exposed out of the upper surface of the tongue plate and an upper welding portion extending out of the base portion. Each lower terminal comprises a lower fixing portion embedded inside the insulation body, a lower contact portion exposed out of the lower surface of the tongue plate, and a lower welding portion extending out of the base portion. The electric connector further comprises a power supply terminal assembly piece. The power supply terminal assembly piece comprises four power supply contact portions exposed out of the upper and lower surfaces of the tongue plate, a slab portion connected with the four contact portions and a power supply welding portion extending out of the base portion. According to the electric connector, integration of the four power supply terminals can be achieved, and therefore a radiating surface can be increased.

The invention discloses a packaging machine capable of being applied to the sampling industry. The packaging machine comprises a machine frame, wherein a sample inlet mechanism, an automatic cover pressing device, a sample discharge mechanism, a conveying mechanism and a control system are mounted on the machine frame; a plurality of sealable charge buckets are arranged on the conveying mechanism; the motion trails of the charge buckets on the conveying mechanism are connected in series with the sample inlet mechanism, the automatic cover pressing device and the sample discharge mechanism in sequence; and the bucket covers of the charge buckets are pressed to the tops of the charge buckets through the automatic cover pressing device, and mineral samples in the charge buckets are packaged in a sealed way. The packaging machine has the advantages of simple structure, easiness in control process, high running reliability, low fault rate, good sealing property and the like.

The invention relates to a monophase electric optical fiber embedded power cable. The power cable comprises a single-copper-core cable conductor consisting of multiple strands of copper wires, an inner semiconductive wrapping band encircling the single-copper-core cable conductor, a conductor shielding layer wrapping the inner semiconductive wrapping band, an insulting layer coating the conductorshielding layer, a semiconductive water-proof layer wrapping the insulting layer and a sheath positioned outside the semiconductive water-proof layer; two semiconductive water-proof layers are provided; an optical fiber cable laid in a form of a sine wave is arranged between the two semiconductive water-proof layers; and the optical fiber cable comprises a reinforcing core made of fiber-reinforced compound material, a plurality of optical fibers adjacent to the reinforcing core made of the fiber-reinforced compound material, an aramid fiber layer encircling the reinforcing core made of the fiber-reinforced compound material and the plurality of optical fibers and a sheath sheathing the semiconductive water-proof layer. The power cable has the functions of optical fiber sensing and opticalfiber communication, improves the degree of intelligence obviously and provides a powerful technical measure for the failure prewarning, information communication and remote monitoring of the power grid and the like.
