The objective of the invention is to provide an electrical connector capable, through a simple structure, of grounding a ground terminal without having to connect to a drain wire, and an electrical connector device using this electrical connector. The electrical connector comprises: signal terminals and a ground terminal; an insulation housing holding the signal terminals and the ground terminal; and a conductive shell covering at least a portion of the outer periphery of a side portion of the signal terminals and the ground terminal. The signal terminals form a pair, and the ground terminal is disposed between the pair of the signal terminals.

When the size of a substrate-side connector mounted upon a substrate is reduced in order to ensure circuit wiring space upon the substrate, the spacing between one terminal group and another terminal group that are retained in an insulated housing within an external conductor shell of the connector becomes even narrower, and thus a technical problem can arise wherein it becomes difficult to reduce or avoid adverse electrical effects such as crosstalk occurring between the terminal groups. In order to solve this problem, the present invention provides a connector in which a housing (150) is composed separately of a first housing member (150a) for retaining a first terminal group and a second housing member (150b) for retaining a second terminal group, an accommodating section (172, 174) for accommodating a conductive member plate (160) is provided in at least one of the surfaces (joining surfaces) joining the first and second housing members (150a, b), and the conductive plate (160) electrically separates the first terminal group and the second terminal group, thereby making it possible to suppress the occurrence of crosstalk and reduce or avoid adverse electrical effects on high frequency characteristics.
The purposes of the present invention are: to improve arm elasticity; and to promote the effective utilization of resources by reducing the quantity of sheet material required to form an arm. The connector comprises an insulating housing, a contact, and an electro-conductive shell, and can mate with a mating connector. The shell includes at least a metal shell made from a single metal sheet. This metal shell comprises a cover part that at least partially covers the side outer peripheral surface of the housing, an elastic arm having a free end on the side that mates with the mating connector, and a support part that is connected to the side of the elastic arm and that elastically connects the cover part and the elastic arm, and that supports the elastic arm in an open-sided beam shape. The cover part and the elastic arm have surfaces that substantially face one another, and the elastic arm has a locking part that locks the mating of the connector and the mating connector at a position further towards the free end side than the support part.
When a housing is to be integrally molded so as to hold a plurality of terminals therein, there is a jig for fixing the plurality of terminals in a fixed position inside a metal mold, and therefore, a material such as synthetic resin hardens around said jig, and after the jig has been removed from the plurality of terminals, a hole is formed by the jig on the outer surface of the housing, the portion exposed to the exterior from said hole is susceptible to external effects, and a technical problem can arise in which the high-frequency characteristics of the connector are readily disturbed. To address this problem, provided is a connector in which the housing is divided into a first housing member (150a) for holding a first terminal group, and a second housing member (150b) for holding a second terminal group, and a plurality of holes (168, 170), which are generated by the jig respectively supporting a plurality of terminals included in the terminal group, are provided where the surfaces (180, 182) of the first and second housing members meet, whereby external effects on high-frequency characteristics can be reduced without holes in the outer surface of the configured housing.
The structure of the outer conductor shell in prior art connectors suffers from the problem that a shell mounting part is formed so as to extend flush to a sidewall, and the part that is not used as the shell mounting part is removed from the shell, so if the plurality of terminals contained in the terminal group held by the housing are equipped with a terminal mounting part positioned alongside in the horizontal direction orthogonal to the fitting direction, it was impossible to adequately cover and protect the periphery of said terminal mounting part, making the connector susceptible to disturbances in high-frequency characteristics. In order to solve this problem, a shell mounting part and protective piece are provided to the sidewall portion protruding in the horizontal direction so as to match the shape of the terminal protecting part protruding to the outside of the housing, and by bending said protective piece so as to curl in over the outwardly protruding terminal protecting part, said terminal protecting part can be adequately protected, the surrounding area thereof can be strengthened, and it is possible to provide a connector in which the effects of external sources on high-frequency characteristics are reduced.
Provided is a connector with improved tensile strength when the connector is forcibly removed from a mating connector. A housing has a body, and a part to be mated that extends towards the side that mates with a mating connector. The diameter of the outer peripheral surface of the part to be mated is at least partially smaller than the diameter of the body. An electro-conductive shell comprises a first shell and a second shell. The first shell includes a cover part that covers at least part of the outer peripheral surface of the housing, an elastic arm having a free end on the side that mates with the mating connector, and a support part that elastically connects the cover part and the elastic arm, and that supports the elastic arm in a cantilevered manner. The elastic arm has a locking part that locks the mating with the mating connector, and a step part corresponding to a stepped surface in the housing provided using the difference in diameter. The second shell has a part that is opposite the step part at a position further towards the side that mates with the mating connector than the step part of the elastic arm.
In conventional connectors, since multiple terminals are not arranged in the same plane maintaining a fixed interval, it is not possible to perform impedance matching for transmission of high-frequency electric signals, which results in the problem of deterioration of high-frequency characteristics. In order to solve this problem, this substrate-side connector is provided with multiple terminals which are arranged in parallel in the same plane and which are bent at a flexed part, an insulator which holds the multiple terminals, and an outer conductor shall which houses said insulator, wherein, by adopting a configuration that reduces change in the interval between the terminals at the flexed part of each of the terminals, the effects on high-frequency characteristics (return, loss, etc.) occurring due to mismatched impedance can be mitigated.

Conventional connectors had the problem that, because in addition to the signal terminals it was necessary to arrange one or more ground terminals between two signal terminal pairs, or between one pair of signal terminals and another pair of signal terminals, the number of components configuring the connector increased, making the internal structure of the connector more complicated. This substrate-side connector is provided with two terminal groups which are arranged so as to face one another along the fitting direction of the connector, an insulator which holds said terminal groups, and an external conductor shell which houses said insulator, wherein a shell mounting unit, for mounting the external conductor shell on the substrate, is passed between the two terminal groups and mounted between a group of terminal mounting units of the terminals included in one terminal group and a group of terminal mounting units of multiple terminals included in the other terminal group, and thereby the shell mounting unit of said external conductor shell can function as a ground terminal.
Conventional connectors faced problems such that, when fitting with a mating connector, if the gap between the two connectors was not properly filled, then, during high-speed transmission of an electrical signal, the connector would suffer deterioration of high-frequency characteristics due to rattling. This connector is provided with multiple terminals, an insulator holding said multiple terminals, and an external conductor shell housing said insulator, wherein, by providing an inclined portion which, rising from the side wall of the external conductor shell, is disposed on the side wall area contacted by the edge portion of a fitting recess of the mating connector, when the fitting part on the external conductor shell distal side of the connector and the fitting recess of the mating connector are fitted together, the gap occurring when a lock protrusion of the connector engages in a lock hole of the mating connector can be prevented in that the edge portion of the opening of the fitting recess of the mating connector is pressed by the inclined portion provided on the side wall of the fitting portion of the connector, whereby the side wall of the lock protrusion is pressed against the inner wall of the lock hole.

The present invention reduces the information used to compensate for the absence of a detection pulse from a magnetic detection unit. As rotation direction information for a movable part (43), "right direction," "left direction," "unknown," and "unknown reverse" are stored. When the absence of a detection pulse is recognized, the rotation direction information is made to be "unknown." Subsequently, when the rotation direction information becomes "unknown," a first adjustment value is used to adjust the rotation variation amount of the movable part, and when the rotation direction information changes from "unknown" to "right direction" or "left direction," a second adjustment value is used to adjust the rotation variation amount of the movable part. Further, when the movable part (43) is in an unknown state as a result of the absence of a detection pulse and the rotation direction thereof changes, the rotation direction information is changed to "unknown reverse." Subsequently, when the rotation direction information becomes "unknown reverse," the rotation variation amount of the movable part is set to zero, and when the rotation direction information changes from "unknown reverse" to "right direction" or "left direction," a third adjustment value is used to adjust the rotation variation amount of the movable part.
