Abstract:
An electrical connector includes an insulative housing having a longitude base with a plurality of contacts retained therein in a first direction, a pair of opposite arms extending from ends of the longitude base in the first direction and a shielding shell includes a top plate and a bottom plate covering on the housing. A receiving space is enclosed with the top plate, the bottom plate of the shielding shell and the pair of arms of the insulative housing. An arm-limited means is unitarily formed on the shell to abut against inside face of the pair of arms.
Abstract:
An electrical connector for mounting on a circuit board includes a longitudinal base and a plurality of contacts received therein. The longitudinal base includes a mating face, an assembling face opposite to the mating face for confronting with an edge of the circuit board. Each contact includes a contacting portion exploding to the mating face and a spring tail extending out of the assembling face for elastically pressing against the circuit board in a height direction perpendicular to the longitudinal direction. A retention pad is secured to the housing and comprises a pressing end for elastically pressing against the circuit board to balance prepressure of the spring tails to the circuit board.
Abstract:
A field emission device includes an insulative substrate, an electron pulling electrode, a secondary electron emission layer, a first dielectric layer, a cathode electrode, and an electron emission layer. The electron pulling electrode is located on a surface of the insulative substrate. The secondary electron emission layer is located on a surface of the electron pulling electrode. The cathode electrode is located apart from the electron pulling electrode by the first dielectric layer. The cathode electrode has a surface oriented to the electron pulling electrode and defines a first opening as an electron output portion. The electron emission layer is located on the surface of the cathode electrode and oriented to the electron pulling electrode.
Abstract:
A vacuum packaging system includes a vacuum room, a delivery apparatus, a discharge device, a second heating apparatus. The delivery apparatus transport the pre-packaged container into the vacuum room. The discharge device discharges a sealing material to seal an exhaust through hole of the pre-packaged container. The discharge device includes a vessel configured for containing sealing material, a transport pipeline, a first heating, and a controlling element. The first heating apparatus softens the sealing material into viscous liquid. The second heating apparatus is mounted on the inner wall of the vacuum room between the second hatch and the transport pipeline.
Abstract:
An electrical connector includes an elongated insulative housing and a plurality of terminals retained in the housing. The housing defines a mating face, a rear wall opposite to the mating face, two slots opening to the mating face and arranged side by side. A plurality of terminals are secured in the insulative housing. Each terminal defines a contact portion exposing to the corresponding slot. A latch integrally extends from the rear wall forwardly and is located between the two slots, the latch has two arms separated by a groove thereby providing resiliency.
Abstract:
A pin connector includes an insulating housing defining pin-retaining-holes and connector pins retained in the retaining holes. Each of the connector pin has a header portion with a soldering face thereof and a shank portion extending from the header portion. The header portion defines notches opening through the soldering face.
Abstract:
An electrical connector includes an insulating housing and contacts made from metallic wire. The insulating housing includes a front portion with a mating cavity and a rear portion. Each contact includes a contacting portion, a leg portion and a connecting portion connecting with the contacting portion and the leg portion. Each leg portion includes a linking portion, a first soldering portion and a second soldering portion. The linking portion connects with the connecting portion and the first soldering portion, and the second soldering portion connects with the first soldering portion. Two soldering portions are on a same plane and parallel to each other.

Abstract:
A stand set includes a first component with a tube-shaped element and two first legs, a second component with a ring-shaped element and two second legs, and a third component with two clamping parts and two openings. The tube-shaped element has two locating ears, each provided with a through hole. An object can be inserted into the tube-shaped element for being supported and the first legs are connected to the tube-shaped element. The ring-shaped element and the tube-shaped element telescope with each other, wherein the first legs are engaged in two notches of the ring-shaped element. The second legs connect the ring-shaped element, each provided with a protrusion being inserted into the corresponding through hole. When detaching the second component from the first component, the third component can be assembled with the second component by inserting the protrusions into the openings and clamping the second legs through the clamping parts.
Abstract:
