ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING THE SAME
Disclosed is an electronic component comprising at least a conductive member, wherein corrosion is prevented or suppressed and high connection reliability is achieved by providing an adequate layer between the conductive member and a main plating layer formed on top of the conductive member. A method for manufacturing the electronic component is also disclosed. The electronic component comprising at least a conductive member is provided, on the surface of the conductive member, with a base plating layer and a main plating layer formed on the base plating layer, and is characterized in that the base plating layer is an electrolytic Ni-P plating layer.
An electrical connector consists of a plug connector and a receptacle connector to be fitted. An insulator is supported only by plug contacts each provided between second and third fixed portions with an elastic portion having at least one snaked portion so as to be floating in a housing. The shape of the second contact portion of each of the plug contacts is substantially in the form of a plate-shaped piece so that the second contact portion of the plug contact and the first contact portion of a receptacle contact are caused to contact each other in line contact at one location, and the elastic portion is arranged within a range from a position below the second contact portion to a position below the insulator. The electrical connector thus constructed is superior in resistance to vibration, and achieves space-saving and floating of the insulator.

A microcontact according to the invention is less than 10 mm in length and composed of a conductive basis material, a base surface treatment layer formed thereon, and an upper surface treatment layer, and includes a contact portion, a terminal portion, and an intermediate portion formed over its entire circumference with exposed oxide surfaces of the base surface treatment layer. The exposed oxide surfaces are formed by irradiating the front and rear surfaces of the contact with laser beams at respective predetermined inclined angles to remove the upper surface treatment layer and simultaneously to oxidize the narrow base surface treatment layer exposed by the removal of the upper surface treatment layer. In this manner, the exposed oxide surfaces can be formed with a high accuracy in a simple manner for stopping solder rise at a predetermined position when the terminal portion of the microcontact is jointed to a substrate by soldering.

A connector to be detachably fitted with a connecting object, includes a required number of contacts, a housing, and a pivoting member acting upon the contacts to bring them into contact with a connecting object. In case of having many contacts, at least one contact is provided with an extended portion at a tip of its pressure receiving portion to extend toward its connection portion, and instead of a pushing portion of the pivoting member acting upon the contact, the pivoting member is provided with an engaging rod to engage the extending portion of the contact. The contact is arranged at an optional position so as to prevent the pivoting member from being warped. The contacts are arranged in a single row, or alternately arranged to be staggered. With the connector thus constructed, the pivoting member is not damaged when pivotally moving after the connecting object has been inserted to achieve a stable electrical connection even with very small pitches of contacts and very thin walls of the housing.
This invention provides a process for producing an electronic component, which can suppress an external force-type whisker without diffusion of component atoms constituting a material (70) and a substrate layer (72) into a tin-containing material layer (74), and an electronic component produced by the process. In the production process, the material (70) is subjected to surface treatment. The production process comprises the step of providing the substrate layer (72) on the surface of the material (70) to surface treat the material (70), and the step of providing a tin-containing material layer (74) above the substrate layer (72) to surface treat the substrate layer (72). The production process further comprises the step of, before the provision of the tin-containing material layer (74), providing a barrier intermediate layer (76) for preventing the component atoms constituting the material (70) and the substrate layer (72) from being diffused into the tin-containing material layer (74) to suppress the occurrence of external force-type whiskers upon the application of external force to the surface of the tin-containing material layer (74).

A grounding structure is provided in an electrical connector, which includes contacts, a housing, a shell, and a ground terminal or a ground lug. The shell has a through-hole communicating with a fitting groove, an installing groove, and a connection portion groove, and the through-hole has an inserting groove into which the ground terminal is inserted, a screw portion for holding the ground terminal, a spacing groove for avoiding any interference with the ground lug integrally mounted on the housing, and an engaging portion to engage a locking portion of the housing. Both the ground lug and the ground terminal are constructed to become electrically conductive with the same shell, respectively, so that grounding is effected by either of the ground lug integrally mounted on the housing and the separately provided ground terminal. It is thus possible to select one contact or the separate ground terminal with respect to the same shell for grounding.
The invention provides an electrical connector achieving a reduced overall height and being capable of preventing an oblique fitting of a plug and a receptacle connector. The plug connector 20 includes contacts 24 and a block 22. The contacts are arranged on both sides of the block to be opposite to each other in the width direction, and the block 22 is formed at longitudinal ends with projection walls 32 higher than upper surfaces 38 of the contacts 24 and provided between the opposite contacts 24 with anchoring recess 34 engaging receptacle connector 50. The receptacle connector 50 includes contacts 54 and a housing 52. The contacts 54 are arranged on both sides of the block to be opposite to each other in the width direction, and the housing 52 is provided with engaging protrusions 64 engaging the anchoring recess 34 and at longitudinal ends with protrusion walls 68 higher than upper surfaces 70 of elastic portions of the contacts 54 and engaging grooves 66 for receiving the projection walls 32. The housing is further provided between the contacts longitudinally arranged with side walls A 69 higher than upper surfaces 70 of elastic portions of the contacts and with side walls B 71 continuous with the side walls A 69 and higher than upper surfaces 73 of contact portions of the contacts.
In a connector, a holding means wherein a pressing section (48) of a turning member (16) can turn is provided between a press-receiving section (34) and a connecting section (36) of an H-shaped contact (14). When the pressing section (48) turns, a rotating shaft (54) shifts to perform small rotation, and a contact section (32) of the contact (14) is brought into contact with a connecting object by turning an operating section (46) in a direction of a fitting port (18) of a housing (12). A notch (82) is arranged on a substrate (80), the connector (10) is connected by having the connector dropped into the notch (82), and fixtures (17) are arranged for fixing to the substrate (80) on the both sides in the longitudinal direction. Protruding pieces (60) which protrude vertically to the substrate (80) are arranged on the side of the connecting section (36) of the fixed contact (14), on the both sides or one side of the connector (10) in the longitudinal direction, integrally with or separate from the fixtures (17). Thus, the rotation angle of the turning member (16) is limited by the protruding pieces (60).

MICROMINIATURE CONTACT AND METHOD FOR MANUFACTURING SAME, AND ELECTRONIC COMPONENT
Provided are a microminiature contact, a method for manufacturing the microminiature contact, and an electronic component, by which an exposed oxide surface which can stop solder piling at a prescribed position can be simply and accurately formed in an intermediate section of the contact, at the time of bonding a terminal section to a substrate by soldering. The contact is composed of a conductive base material, and a base surface treatment layer and an upper surface treatment layer formed on the conductive base material. The contact is composed of a contact section (2), a terminal section (3) and the intermediate section (4). In the intermediate section (4), the exposed oxide surface (5) of a base surface treatment layer is formed over the entire circumference. The exposed oxide surface (5) is formed by irradiating front and rear planes (1a, 1b) of the contact (1) with laser beams at prescribed inclined angles (&thetas;a, &thetas;b), respectively, and removing the upper surface treatment layer and oxidizing a narrow base surface treatment layer exposed by such removal at the same time. Thus, the microminiature contact having a total length of 10mm or less is formed.

A connector includes contacts and an insulator. Each contact includes a contact portion, a first fixed portion, an elastic portion substantially in the form of a crank, a second fixed portion and a connection portion. The insulator includes a fixation block to which the second fixed portions are fixed, and a movable housing to which the first fixed portions are fixed. The movable housing is fixed only to the contacts and held by the elastic portions in a floating condition away from the bottom surface of the fixation block. The fixation block has a wall for preventing short circuit when the connector is being mounted on a substrate. A floating amount of more than 0.7 mm can be achieved with a simple construction without causing short circuit with a substrate when the connector is being fitted with a mating connector and without causing any failed connection.
A connector (14) formed in a roughly H-shape, comprising a first piece (28) having a contact part (32a) and a pressingly receiving part (34), a second piece (30) having a contact part (32b) and a connection part (36), and a connection part (38) connecting them to each other. A holding means allowing the pressing part (48) of a rotating member (16) to rotate is installed between the pressingly receiving part (34) and the connection part (36). Preventive walls (22) preventing a ceiling part (20) from being raised when a connected member is twisted upward are formed in a housing (12) at the ceiling part (20) and at least at both ends of the ceiling part (20). The rotating member (16) comprises an operation part (46), a pressing part (48), and locking holes (50) formed independently of each other. The operation part (46) is rotated in the direction of the fitting port (18) of the housing (12), and the contact parts (32a) and (32b) of the contact (14) are brought into contact with the connected member.
A connector includes a plurality of contacts each having at one end a contact portion adapted to contact a connecting object, at the other end a connection portion to be connected to a substrate or the like, and between the contact and connection portions a fixed portion to be arranged and held in a housing so that the contact portion is displaceable about the fixed portion as a fulcrum in a cantilevered manner relative to the housing arranging and holding the contacts. If the thickness of the housing where the contact portions of the contacts are displaceable is not more than 0.6 to 0.7 mm, the housing is provided with a protrusion formed with a hole to permit the contact portions to be displaceable in the hole, thereby ensuring sufficient contact pressures to obtain stable connection with a mating connector without unintended deformations of the contacts.
A connector includes substantially H-shaped contacts; fixtures fixing the connector to a substrate on longitudinal ends; a housing having a ceiling portion covering contact portions of the contacts, a protection wall at the end of the ceiling portion on the fitting opening side for preventing raising of the ceiling portion on being accidentally forced upward, extension walls at the longitudinal ends for holding the fixtures, and slits each between the extension wall and a bearing for a pivoting member; and the pivoting member having an actuating portion, urging portions, and anchoring holes and mounted on the housing such that between the connection portions and the pressure receiving portions of the contacts the urging portions perform a compact pivotal movement with rotation axis moving. The connector is mounted on one side surface of the substrate to achieve more reduced overall height and superior operationality of the pivoting member.
