摘要:
A zero force electrical connector is adapted for terminating a flat cable. The connector includes a dielectric housing mounting a plurality of conductive terminals. The housing has a first end adapted for receiving the flat cable in engagement with the terminals, a rear end and opposite sides. An actuator is mounted to the housing for movement between a first position allowing free insertion of the cable into engagement with the terminals and a second position biasing the cable against the terminals. Complementary interengaging stops are provided between the housing and the actuator near the rear end of the housing for limiting rotation of the actuator relative to the housing in a first direction. Complementary interengaging latches are provided between the housing and the actuator near the front end of the housing for preventing rotation of the actuator relative to the housing in a second direction opposite the first direction.

An electrical connector is provided for terminating a flat cable. The connector includes a housing mounting a plurality of terminals in a generally parallel array. The housing has opposite sides and a front end, with an opening between the sides for receiving an end of the flat cable in engagement with contact portions of the terminals. A pressure member is rotatably mounted on the housing for movement between a first position allowing insertion of the flat cable into the opening and a second position pressing conductors of the flat cable against the contact portions of the terminals. Overhanging extensions project inwardly from the opposite sides of the housing to prevent release of the flat cable from the connector in the event undesired external forces are applied to the cable which would tend to bias the pressure member toward its first position.

Disclosed is an improved board-surface mounting type electric connector whose pin terminals are designed to be soldered to a printed circuit pattern by their tail sections. Each tail section is composed of a soldering portion, an intermediate stepwise joint and a non-soldering portion. The soldering portion of the tail section is laid on the printed board, and the non-soldering portion is laid on an isolation wall at a level higher than the printed board, thus leaving space between the printed board and the non-soldering portion available for printing desired circuit patterns. Connector housing may have at least one stopper to abut on the upper surface of each soldering portion for preventing it from rising, thereby keeping each soldering portion stable in position.

An electrical connector is disclosed for connecting a flat cable. The connector includes a dielectric housing mounting a plurality of conductive terminals. The housing has a front end adapted for receiving the flat cable in engagement with the terminals, a rear end and opposite sides. An actuator is pivotally mounted on the housing for pivotal movement between a first position allowing insertion of the flat cable into engagement with the terminals and a second position biasing the cable against the terminals. An independent engagement part is mounted on the housing and includes a pivot about which the actuator is pivotable between said positions.

A piezoelectric speaker includes: a piezoelectric vibrator including a piezoelectric body formed of a piezoelectric element and a plate-shaped body which has a larger diameter than the piezoelectric body and which is attached to a surface of the piezoelectric body in a concentric form; and a film-shaped body that is provided around the piezoelectric vibrator so as to elastically hold the piezoelectric vibrator. The film-shaped body includes a coarse and dense portion in a circumferential direction thereof, which has a physically coarse portion which can become a mountain portion or a valley portion or both, and which is disposed so as to correspond to a natural frequency of an in-phase mode in which antinodes and nodes are formed in a concentric form. The piezoelectric vibrator and the film-shaped body form a sound producing body.

The mapping data include a substituting element describing area, a repeat number describing area, and a repeat element describing area. In the substituting element describing area, it is described that the input data is set to which tag in the XML file. In the repeat number describing area, the repeat number specified in the repeat number specifying area is described. In the repeat element describing area, it is described that the tag name of the tag output repeatedly in the XML file. The hierarchy structure data generating system outputs the repeat tag to belong to the same rank as the tag of the repeat element describing area. On putting out the repeat tag, the hierarchy structure data generating system outputs it repeatedly the same number of times as the number of the value of the repeat number describing area.

Disclosed is a board-to-board electric connector using terminals whose width is same in size as the thickness of metal sheet from which terminals are stamped out, thereby permitting reduction of terminal pitch to possible minimum simply by selecting the metal sheet.

Disclosed is an electrical connector comprising a multi-terminal plug and multi-terminal socket in which each female terminal is composed of a contact section, a solder tail section and intermediate curved joint integrally connected to the contact section and the soldering tail section. The curved joint of each female terminal will be yieldingly bent when an external force is applied to push the male terminal in the female terminal, thereby absorbing the external force and preventing deformation of the solder tail section, and hence peeling-off or cracking of solder at the solder tail. The intermediate curved section will also permit the contact section to float in order to compensate for the misalignment of the contact section relative to its mating pin.

An electrical contact is disclosed for use in an electrical connector to be surface mounted to a printed circuit board. The contact includes an inverted U-shaped portion defining a pair of depending legs. One of the legs has a foot portion for electrical connection to an appropriate circuit trace on the printed circuit board. A terminal portion is turned upwardly from a distal end of the other leg for termination with an appropriate mating terminal. The contact is in the form of a one-piece metal component. In the preferred embodiment, the terminal portion of the contact is in the form of a terminal pin, with the pin and the legs of the inverted U-shaped portion of the contact all being generally parallel.
摘要:
An electrical connector used for interconnecting one or more conductors on the same or different printed circuit boards comprising two mold members having terminal bodies with each end inserted into the mold members until they protrude from the bottom and with a bent portion between the mold members maintaining a distance greater than the distance required to insert the mold members and terminal bodies into through holes of a printed circuit board. The connector is used in conjunction with a pair of chuck members and a stop member to place the connector mold members in alignment so that the protruding terminal portions can be accurately inserted into through holes of a printed circuit board with the use of automatic robot means.
