An image forming apparatus, such as a copier and a printer, includes a structure or assembly for electrically connecting a high-voltage circuit board with an electric component of the image forming apparatus such as charger unit, developer unit and image transfer unit. The structure or assembly includes a circuit board attaching member which holds the high-voltage circuit board, and a contact terminal extending through the circuit board attaching member to be in contact with the high-voltage circuit board and the electric component for the electric connection therebetween. The contact terminal may have a rod shape and the circuit board attaching member may be formed with a cylindrical guide member having a through hole through which the contact terminal extends.

A metallic thin film 15 is formed on a mold 11 having protrusions 12 complementary in shape to a conductor pattern to be formed; a substrate 17 having a transfer layer 16 of adherent (or adhesive) material applied to one side surface thereof is provided; and the transfer layer 16 side of the substrate is brought into intimate contact with the metallic thin film 15 laid over the protrusions 12, followed by pulling the transfer layer apart from the mold so as to transfer the metallic thin film 15 covering the protrusions 12 onto the transfer layer 16 to thereby form the conductor pattern 18 on the transfer layer 16. The metal film may include cooper and a weak adherence layer 13 which may be gold.

A contact sheet for providing an electrical connection between two or more electronic devices each having spherical or planar terminals is provided. The contact sheet includes a plurality of insulative elastic substrate sheets having a plurality of through holes formed therethrough and a plurality of conductive elastic contacts each having a first end interposed and fixed between two of the insulative elastic substrate sheets at a fixed point proximate an edge of a respective through hole, and a second end arranged to bend as a cantilever extending from the fixed point. Each contact also includes a centrally located bending portion. The width of the contact continuously varies to be greater at portions of the contact which are subjected to larger stresses and less at positions of the contact which are subjected to smaller stresses when a load is applied to the second end of the contact.

An electrical connector (2) for connecting a land grid array (LGA) chip (3) with a printed circuit board includes a housing (20) and terminals (21) received in the housing. Two cylindrical posts (201, 202) extend upwardly from diagonally opposite corners of the housing. Two recesses (301, 302) are defined in diagonally opposite corners of the LGA chip. The LGA chip is inserted into the LGA connector, with the recesses interferentially receiving the posts. Thus the LGA chip is securely mounted on the housing, with the posts and the recesses cooperating to precisely position the LGA chip on the LGA connector. This ensures that engagement between contact pads (300) of the LGA chip and the terminals is highly accurate and reliable. Further, the posts are sized differently from each other, and the recesses are correspondingly sized differently from each other. Mismating of the LGA chip with the LGA connector is prevented.

An electrical connector housing includes a first shell, the top face of which carries connector mounts, fuse mounts and relay mounts. It further includes a second shell, the bottom face of which carries second connector mounts. The second shell is then fitted to the first shell. The electrical connector housing contains a bus bar stack, first and second flexible printed boards and a printed board. The first and second flexible printed boards are superposed to each other in the electrical connector housing, so that the copper foil patterns contained therein can be electrically connected by welding.

A super mini coaxial microwave connector having a receptacle part and a plug part. The receptacle is a metal connector body associated with an insulator, at the lower end thereof. The insulator extends into the connector body and provides an upper projection end. The projection end at the inner part, engages with a male terminal and the lower end of the male terminal extends outward from the insulator and the connector body. The upper end of the male terminal is a round end. The plug part has a metal casing and the metal casing joins with another insulator. The insulator has a central hollow part to fit with a female terminal. The female terminal at the upper plate thereof has an extending downward stop neck and two downward stop plates extending from both ends of the rear side of the stopper respectively.

An electrical connector (1) comprises an insulating housing (10) defining a number of terminal receiving channels (140) and a first and a second openings (102, 104) in communication with the receiving channels, and a pair of terminal inserts (20, 30) respectively inserted into the first and the second openings. Each terminal insert includes an insulating portion (22, 32) and a number of terminals (24, 34) retained in the insulating portion. Each terminal has a mating portion (240, 340) received in a corresponding terminal receiving channel of the housing.

摘要:
A connector board which interfaces a disk drive head assembly to a test apparatus. The connector board is capable of being separated into segments which facilitate head assembly testing without changing connector boards, wherein test connections may be established supporting differing numbers of head assembly wires. By way of example, the connector board is adapted so that it may be used with either four-wire heads or two-wire heads, and further provides simplified separation should only a two-wire connection be required.
