Abstract: An electrical connector includes: an insulating body; plural conductive terminals disposed in the insulating body, the conductive terminals including two signal terminals and one ground terminal arranged between the two signal terminals; a cable connected with the conductive terminals; and a metal shell disposed outside the insulating body, the metal shell including a top wall, an opening being set on the top wall, the shape of the opening being rectangular, the top wall being provided with elastic pieces protruding inward from the opening to electrically connect with the ground terminal, wherein the opening is sized and configured to achieve better electrical performance of the conductive terminals.

Abstract: A lateral core-pulling mechanism of mold includes a cavity plate, a cavity insert configured in the cavity plate and defining a shaping recess, and a core-pulling body including a first slide module longitudinally movably disposed in the front of the cavity plate, an angular pin, and two second slide modules movably disposed at two sides of the cavity insert. The first slide module defines an inclined hole, a first shaping core inserted into the shaping recess and two first guide surfaces at two side edges thereof. The angular pin has an inclined block inclining forward and movably received in the inclined hole to drive the first slide module to move forward or backward. The second slide module defines a second shaping core inserted into the shaping recess and a second guide surface slidably matching the corresponding first guide surface to drive the second slide module to move sideward.

Abstract: A side core-pulling mechanism of mold includes a slide block, an impacted block and a wobbly block. The bottom of the slide block projects outwards to form a columnar pin. The front surface of the impacted block defines a receiving cavity, a first slot and a second slot. The first slot upright extends downwards to pass through the bottom of the impacted block from the over place of the right end of the receiving cavity and communicates with the right end of the receiving cavity. The second slot extends rightwards and downwards to pass through the bottom of the impacted block from a start end of the first slot. The first and second slots communicate with each other. The columnar pin is movable in the first and second slots. The wobbly block is received in the receiving cavity of the impacted block. The wobbly block is against the bottom wall of the receiving cavity to cut off the first slot at a nature status and rotates upwards in the receiving cavity for making the first slot be in a through status.

Abstract: A mold with a returning apparatus includes a female and a male mold. The male mold has a fix plate with a through bore, a lower eject plate, an upper eject plate, an eject pin fixed to the upper eject plate, and a returning apparatus. The returning apparatus has a pull rod and a returning portion having a gap. The pull rod defines a top at one end thereof, a surrounding portion adjacent to the top, and a compression formed between the top and the surrounding portion. The gap has a first cavity at an upper portion thereof, a second cavity communicating with the first cavity at a lower portion thereof, and a step formed therebetween. The size of the first cavity is bigger than the second cavity. The top is received in the first cavity, the surrounding portion is received in the second cavity, and the compression abuts against the step.

Abstract: A mold for a secondary molding includes a lower mold insert, an upper mold insert coupled to the lower mold insert, and an extraction device loaded in the lower mold insert. The lower mold insert has a lower container, a couple of lower notches adjacent to the two opposite sides of the lower container respectively and a lower cavity with two opposite sides connected to the lower notches respectively. The extraction device has an inserting core. The inserting core includes a body with two molding portions at its opposite sides. The body is inserted into the lower container, the molding portions project into the lower cavities.

Abstract: An apparatus for periodically cooling injection mold has a cavity formed between a cavity insert and a core insert of the injection mold. The bottom of the cavity defines a perforation that extends and passes through a lower pushing plate. An ejector pin is received in the perforation. The bottom end of the ejector pin passes out of the lower pushing plate and is above the top surface of a lower fixed plate. A sensor switch that controls several electric valve actuators is located on the lower fixed plate and is below the ejector pin. The electric valve actuators control cooling liquid to flow into several cooling pipes that are configured in the cavity insert and the core insert respectively. A method for periodically cooling injection mold includes the steps of: closing the injection mold and pouring raw materials into the cavity to form a product; pushing the ejector pin downward along the perforation and the bottom of the ejector pin touching and pressing the sensor switch.

Abstract: A side core-pulling mechanism of mold includes a slide block, an impacted block and a wobbly block. The bottom of the slide block projects outwards to form a columnar pin. The front surface of the impacted block defines a receiving cavity, a first slot and a second slot. The first slot upright extends downwards to pass through the bottom of the impacted block from the over place of the right end of the receiving cavity and communicates with the right end of the receiving cavity. The second slot extends rightwards and downwards to pass through the bottom of the impacted block from a start end of the first slot. The first and second slots communicate with each other. The columnar pin is movable in the first and second slots. The wobbly block is received in the receiving cavity of the impacted block. The wobbly block is against the bottom wall of the receiving cavity to cut off the first slot at a nature status and rotates upwards in the receiving cavity for making the first slot be in a through status.

Abstract: An injection die with an early-returning apparatus includes a lower fixed plate; a plurality of padding blocks located in the lower fixed plate; a male die mounted on the padding blocks; a female die coupled with the male die; an upper fixed plate mounted on the female die; a draw core unit installed in the female die; a shaft seat unit located in a space between the padding blocks and mounted on the lower fixed plate; a restoration unit fixed on a shaft-fixing plate of the shaft seat unit and inserted into the male die and an early-returning apparatus mounted on the shaft seat unit and the upper fixed plate and inserted into the male die and the female die.
