Abstract: A hinge connects a display to a base of a notebook. The display has two sides and a bottom edge. The hinge has a stationary leaf, a bearing, a bracket and two pivoting leaves. The stationary leaf is mounted on the base. The bearing is formed on and at a relative incline to the stationary leaf. The bracket is parallel with respect to the base, but when the bracket rotates on the bearing, the bracket changes angle relative to the base until the bracket corresponds to the incline of the bearing. This raises an end of the bracket over the base and allows the display to rotate.

Abstract: A hinge has a stationary leaf, at least one barrel, a pivoting leaf and a pivot pin. The at least one barrel is formed on the stationary leaf and each has an inner surface, a pivot pin hole, a gap and an inner lubricant groove. The pivot pin hole is defined coaxially through the at least one barrel. The gap communicates with the pivot pin hole. The inner lubricant groove is defined in the inner surface. The pivot pin is protrudes from the pivoting bracket, is mounted rotatably in the pin hole in each of the at least one barrel and has multiple annular lubricant grooves communicating with the inner lubricant groove in each of the at least one barrel. The inner lubricant groove and the annular lubricant grooves hold sufficient lubricant to provide superior lubrication between the pivot pin hole and pivot pin.

Abstract: A pivotal hinge has a seat and a shaft, and a first end of the shaft is inserted into the seat. A second end of the shaft is inserted into multiple washers, a first and a second positioning ring, multiple elastic rings and a cushion ring in turn. The first positioning ring can be positioned relative to the second positioning ring and with the friction force of the washers, the excellent position effect can be achieved. Hence, a cover of a laptop computer can be positioned to the chassis of the laptop computer at a desired height.

The rotation portion has an extension extending from a bottom of the sleeve to be received in a through hole defined in the circular wall so that the rotation portion is able to be rotatable relative to the fixed portion. The extension has a flange formed thereon and a sectorial block formed on an outer periphery of the flange. The circular wall has a limiting boss formed on a peripheral edge thereof to be selectively connected to the sectorial block so as to limit the rotational movement of the rotation portion relative to the fixed frame.

Abstract: A robust hinge has a redundant positioning capability, is mounted between a cover and a base and has a keyed pivot pin, a rotating leaf, a stationary leaf and a spacer assembly.

The spacer assembly is mounted around the keyed pivot pin and has primary and secondary rotating positioning elements and a secondary stationary positioning element. Each stationary positioning element has a detent. Each rotating positioning element has a protrusion corresponding to the detent. The protrusions engage the detents to provide the redundant positioning capability to keep the cover form hitting the base. Two pairs of protrusions and detents provide the redundant positioning capability.

Abstract: A hinge includes a sleeve and a shank. The shank is composed of an elongated body, a connecting portion and a securing portion. The connecting portion has a diameter smaller than that of the elongated body and larger than a diameter of the securing portion. The sleeve has an inner diameter smaller than that of the connecting portion such that after the connecting portion is received inside the sleeve, an interference fit is existed between the sleeve and the connecting portion of the shank.

Abstract: A hinge mounted between a cover and a base of a notebook has a base bracket having a mounting hole, a cover bracket having a stationary hole, a limiting spacer and a pintle. The limiting spacer is mounted securely on one side of the base bracket and has a mounting hole and a limiting flange. The pintle has a proximal end mounted securely in the stationary hole of the cover bracket, a distal end mounted rotatably through the mounting hole of the limiting spacer and the mounting hole of the base bracket, and a head formed near the proximal end. The head has a limiting protrusion selectively abutting a front end or a rear end of the limiting flange to keep the cover of the notebook in position when the cover being closed or opened and to prevent the base bracket from resulting stress concentration.

Abstract: A pivot hinge for a portable electronic device is disclosed. A base plate with a pivot tube is fixed on the main unit of the portable electronic device, and a locating bracket is fixed on the movable display panel. A shaft is inserted through the pivot tube, exposing the angular section from the other end of the pivot tube. A locking piece, a spring, and a ring are sequentially inserted over the angular section to complete the spring assembly. The interlocking of the tooth and notch enables the movable display panel to be placed in the horizontal direction over the main unit. A middle section of the shaft and the pivot tube are closely mated only when two plain facets respectively formed on the shaft and the pivot tube are matched up in the rotation of the shaft, thus abrasion damage is significantly reduced.

Abstract: A coaxial cable connector includes a transmission tube having four corresponding elastic strips at each of two ends thereof. The four elastic strips are disposed in the transmission tube in a bent manner, and each elastic strip is formed with a projecting plane and inclined planes. Side edges of the four elastic strips are joined to form a clamping end for inserting and connecting an axis of a coaxial cable therein. According to the aforesaid structure, while curling up a metal plate to form a transmission tube, the four strips extended from two ends are bent in the transmission tube in a consecutive manufacturing process. Projecting planes of the four elastic strips are all capable of coming into contact with the axis of the coaxial cable, thereby enlarging contact areas for increasing signal transmission efficiency as well as preventing terminals from damages.

Abstract: A securing device includes a body adapted to securely connect to the primary plate and two arms vertically extending out from two opposite ends of the body. Each of the arms has an assembly hole to adapt to align with opposite ends of a tubular connector of the primary plate so that when the shaft extends into the tubular tube, the two arms are secured to the shaft. When a radial force is acting on the shaft, the force is compromised by the two arms of the securing device such that damping of the screen is minimized.
