Abstract: A receptacle that can detect the insertion and extraction of a plug includes: a receptacle shell having formed therein a plug insertion port into which the plug is inserted and from which the plug is extracted; a receptacle body provided inside the receptacle shell; a movable contact that is installed at a base portion of the receptacle body, the base portion faces a distal end of the plug inserted into the plug insertion port, and that is deformed elastically when pushed by the plug; and an immovable contact that is installed at the base portion, is normally spaced from the movable contact, and comes into contact with the movable contact when the movable contact is pushed by the plug and elastically deformed. The receptacle that can conform to the HDMI standard can be realized without adding any modification to main components relating to mating with a plug.

Abstract: The object of the present invention is to provide a locking structure of a flexible board, which combines a reliable locking of and a smooth removal of the flexible board inserted to the Non-ZIF type connector, does not widen the width of the flexible board, and thereby does not increase the occupied mounting area of the connector, and furthermore does not compromise one-action insertion and removal.

Abstract: A microconnector in which elastic contact force is improved and a manufacturing method of a socket therefore, are provided. The microconnector includes: the socket 10 in which plural cantilever terminal blocks 14 having pressure receiving parts 16 are integrally formed on a board 11 made of single crystal silicon, and socket leads 15 are disposed on the terminal blocks 14; and a plug 20 in which plug leads 21 corresponding to the socket leads 15 are provided on a plug board 23. The manufacturing method of the socket 10 includes: a step of applying a resist to one surface of the board 11; a step of patterning the terminal blocks 14 by photolithography; a step of performing anisotropic etching to form the terminal blocks 14 to predetermined heights while a bottom is made to remain; a step of applying a resist to the other surface of the board 11; a step of patterning the pressure receiving parts 16 by photolithography; and a step of performing isotropic etching to remove the bottom.

Abstract: A connector mounting structure on a circuit board is presented. A connector has a plurality of terminals comprising first terminals separated with a predetermined pitch and second terminals separated with a pitch larger than the predetermined pitch. The first and second terminals have respectively a first tail part facing toward the circuit board and a second tail part bent toward the circuit board after extending in the lateral direction from the connector housing. The first tail part is reflow-soldered to a land part formed on a surface of the circuit board, and the bent top end of the second tail part is inserted into a mounting hole penetrating another land part formed on the circuit board and reflow-soldered. In this mounting structure of the connector, it is simultaneously possible to narrow a pitch between terminals and to increase the peeling strength.

Abstract: An agent for fixing (a) substance(s), which can fix various substances to be fixed on a substrate via covalent bonds and which has an excellent effect for the prevention of non-specific adsorption is disclosed. A polymer containing a plurality of phosphorylcholine groups and photoreactive groups in one molecule is used. The polymer binds to the substrate and to the substance to be fixed via the photoreactive groups, thereby the substance to be fixed is bound to the substrate via covalent bonds through the polymer, and non-specific adsorption is effectively prevented by the phosphorylcholine groups. Further, an agent for fixing (a) substance(s) for fixing the substance on a substrate, comprising a nonionic water-soluble macromolecule having at least 2 photoreactive groups in one molecule was also provided.

A connector has a plurality of terminals comprising a first terminal separated with a predetermined pitch and a second terminal separated with a pitch larger than the predetermined pitch. The first and second terminals have respectively a first tail part facing toward the circuit board and a second tail part bent on the circuit board side after extended in the lateral direction of the connector housing. The first tail part is reflow-soldered to a land part formed on the surface of the circuit board, and the bent top end of the second tail part is inserted into a mounting hole penetrating the other land part formed on the circuit board and reflow-soldered.

Abstract: The present invention provides a connector able to be made thin so as to satisfy the needs of making an electronic device further light in weight, thin, short and compact. Therefore, the connector has a connector main body having a housing for storing a contactor and having an opening portion, and an actuator rotatably supported with respect to the connector main body. A flexible cable inserted into the opening portion and the contactor come in press contact with each other by the actuator and are electrically connected to each other in the rotation of the actuator. A metallic cover for covering a portion of the housing and having a receiving portion is arranged in the connector main body. When the actuator makes the flexible cable inserted into the opening portion come in press contact with the contactor, the receiving portion receives reaction force of the press contact. Thus, the thin type connector can be provided.

Abstract: There is disclosed a printed board connector which inhibits flux from rising in a housing by means of a capillary phenomenon, prevents contacts from being solidified and also prevents solder bridges from being generated. Stands are provided on opposite sides of an under surface of the housing to form an under space common to terminal portions of contacts between the opposite stands.

Abstract: There is disclosed a printed board connector whose leg structure has a high strength, is further provided with an appropriately strong spring property and can securely fix a connector to a printed board even if there is a slight dispersion in dimension precision. A pair of right and left leg components are extended from an under end surface of a housing, and spaced apart from each other. Tip-end portions of the leg components are interconnected to form an integral structure of a leg. At least one of the leg components has on its outer side surface a substantially hemispheric projection to be engaged in a fitting hole of the printed board. The leg component also has a V-shaped hollow portion on its inner side surface, with the top portion being positioned on a substantially horizontal center line of the projection.
