Abstract:
A mobile wireless communications device may include a housing, a printed circuit board (PCB) carried by the housing, at least one wireless RF circuit carried by the PCB, and a first contact(s) carried by the PCB and electrically connected to the at least one wireless RF circuit. The device may further include a wrap-around antenna assembly comprising an antenna retainer frame removably coupled to an edge of the PCB and having first and second portions wrapping around adjacent first and second surfaces of the PCB at the edge thereof when the antenna retainer frame is coupled to the PCB. The wrap-around antenna assembly may also include an antenna carried by the antenna retainer frame and extending along the first and second portions thereof. The antenna may include a second contact(s) removably coupled to the first contact(s) when the antenna retainer frame is coupled to the PCB.
Abstract:
A method of making a flat-plate antenna having thinner shape and excellent productivity, reducing labor for installation in an electrical apparatus or on a wall, and exhibiting desired antenna characteristics stably. The method includes forming a conductive flat-plate having a slit portion, a radiating element portion, and a ground portion formed by press punching a lead-frame. The method also includes laminating over the lead-frame with a resinous film. The method further includes forming first and second connecting holes through which a part of the lead-frame is exposed. The method also includes press punching the laminated lead-frame including the slit portion, the radiating element portion and the ground portion. The method still further includes connecting first and second conductors of a power supply line with the radiating element portion and the ground portion, respectively.
Abstract:
A compact memory card connector with an extended communication distance is provided. This connector has a loading port at its one end, through which a memory card can be accommodated therein. The connector is equipped with a base made of an electrical insulating material, a plurality of contacts arranged on the base so as to electrically contact connecting terminals of the memory card inserted in the connector, and an antenna block, which houses a secondary antenna and is slidable in a direction of inserting the memory card into the connector.
Abstract:
The present invention relates to a coaxial connector comprising:a first connector element forming a socket, having a first body, a resilient return member, and a first central contact element having a first front end, the contact element being movable against the action of a resilient return member, at least in sliding relative to the first body; anda second connector element forming in particular a plug, arranged to be capable of being releasably connected to the first connector element, and comprising a second body and a second central contact element having a second front end;wherein the first and second central contact elements are arranged in such a manner that when the first and second connector elements are connected together, the contact elements bear one against the other via their front ends.
Abstract:
The present invention relates to a USB network adapter, especially relates to a USB network adapter comprising a wireless network interface card contained in upper and lower shells and having a coaxial connector extending from a signal receiver of a wireless network interface card. The upper and lower shells having a half circular opening at one end, a half hexagonal flange located adjacent the half circular opening and a seat having a half circular recess for firmly holding the coaxial connector therebetween. Whereby, the coaxial connector is connectable a coaxial connector 7 extending from an antenna to enhance the quality of the wireless communications.
Abstract:
An improved plug connection device has projections aligned parallel with the axial direction of the connectors, by means of which the connector unit is positioned or can be positioned perpendicularly to the plane of the printed circuit board. The connector unit has, on the side facing the printed circuit board, devices forming a support surface and/or boundary plane, on which the adjacent plane of the printed circuit board lies on the connector unit. The connector unit has on a side facing the printed circuit board, at least in sections, a free space (X1), provided with at least one recess and/or recesses. The recesses lie at a distance to the adjacent plane of the printed circuit board, and/or bathe outer contacts of the connectors are arranged transversely offset to one another in such a way that a free space (X2) is formed between the connectors. The free space (X1) and/or the free space (X2) serve as room for routing and/or populating the printed circuit board.
Abstract:
By forming a coaxial receptacle and a coaxial plug, for which the characteristic impedances have been adjusted, at the respective end portions of a receptacle-side insulating housing and a plug-side body constituting a multi-connector being a parallel connector part, a transmission line has been made possible in which a multi-connector is mated and the signals passing through the coaxial connector at the same time exhibit little reflection and radiation.
Abstract:
A connector for antenna includes a hollow casing having a flange and an annular protrusion extending inward from an inner periphery thereof. A plurality of notches are defined through the annular protrusion. A terminal has a first end inserted into the first end of the casing and a stop ring is mounted on the terminal to seal the first end of the casing. A C-shaped spring member is mounted on the terminal and including a C-shaped body and two legs which are engaged with the notches of the annular protrusion. The C-shaped body is located between the flange and the annular protrusion. The spring member is well positioned so that it is not rotated when the antenna is rotated and no noise is generated.
Abstract:
Integrated unit (1) having a connector (3) mounted on a printed circuit (2), the connector having a support (4) in which are placed a first blade (5) and a second blade (10) linked to the printed circuit, the first blade having on an upper side (8) of the support, an extension (7) forming an antenna (6). This first blade is preferably formed by the metallisation of the plastic support. The second blade comes into contact with the first blade. The support has a cavity (18) to receive a coaxial plug (25) and thus to switch the connection between the first and second blades, for a new connection between this second blade and the coaxial plug.
Abstract:
A housing holds a first contact partner adjacent a throughgoing hole in the housing. Electrical contact is made between this first contact partner and a second contact partner outside the housing by a device having an electrically conductive and elastically deformable contact element engaged with all-around play in the hole between the contact partners and bearing elastically in one direction on the first contact partner and elastically in an opposite direction on the second contact partner. This element is formed with a flange bearing peripherally on the housing around the throughgoing hole.
