The present invention relates to a cavity filter and a connecting structure included therein. The cavity filter includes: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein the terminal portion includes: a first side terminal contacted with the electrode pad; and a second side terminal having a housing space in which a part of the first side terminal is housed, and connected to the RF signal connecting portion, wherein the first side terminal is provided as an elastic deformable body whose part is radially widened or narrowed against an assembly force provided by an assembler. Therefore, the cavity filter can efficiently absorb assembly tolerance which occurs through assembly design, and prevent disconnection of an electric flow, thereby preventing degradation in performance of an antenna device.

The present invention relates to a connecting apparatus including a fixed terminal part having a hollow portion and fixed in a predetermined space between a first substrate, on which electrical components are mounted, and a second substrate disposed in parallel with the first substrate, one terminal part fixed to one end of the fixed terminal part and configured to be elastically supported on the first substrate, one terminal part being configured to slip and come into contact with an inner surface of the first substrate, and the other terminal part fixed to the other end of the fixed terminal part and configured to be elastically supported on the second substrate, the other terminal part being configured to slip and come into contact with an inner surface of the second substrate, in which one terminal part and the other terminal part are elastically supported by an elastic member installed in the hollow portion of the fixed terminal part and configured to be extended or contracted, thereby providing an advantage of easily absorbing assembling tolerance existing between two substrates and provides a very simple assembling process.

A magnetic connector includes a first insulating housing, a printed circuit board, a plurality of magnetic bodies, a plurality of terminals and a second insulating housing. The first insulating housing has a bottom wall, a side wall, a recess being defined between the bottom wall and the side wall. The printed circuit board is received in the recess. The magnetic bodies are mounted to the printed circuit board. The terminals are mounted to the printed circuit board. The second insulating housing is mounted to the top of the first insulating housing and is covered the recess. The magnetic bodies and the terminals are exposed from a top surface of the second insulating housing. As described above, the magnetic bodies are mounted to the printed circuit board, and then the magnetic bodies are magnetized. Hence, manufacture cost of the magnetic connector is saved.

A terminal module (10) has a metal case (20) with a ceiling wall (21), a bottom wall (51) facing the ceiling wall (21), opposed side walls (23) extending from the ceiling wall (21) toward the bottom wall (51) and retaining pieces (24). A coil spring (40) is sandwiched between the ceiling wall (21) and the bottom wall (51). The retaining pieces (24) face each other in a direction perpendicular to a facing direction of the side walls (23) and project toward the bottom wall (51) from the periphery of the ceiling wall (21). The side walls (23) and the retaining pieces (24) are disposed alternately on the periphery of the ceiling wall (21). A spring receiving portion (26) formed by the ceiling wall (21), the side walls (23) and the retaining pieces (24) receives an end part of the coil spring (40) on the side of the ceiling wall (21).

In example implementations, an apparatus includes a housing. The housing includes an electronic connector coupled to a back side of the housing. In addition, the housing includes a pin coupled to a front side of the housing and in communication with the electronic connector. At least one alignment magnet and at least one wireless transceiver chip is coupled to the housing. At least one waveguide is coupled to the at least one wireless transceiver chip.

An interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together and formed by bending a first metal plate having a high modulus of elasticity. An exterior body is formed by bending a second metal plate having low electric resistance. A movable portion of the interior body includes a contact portion and elastic arms. Each of the elastic arms includes, at its tip portion, an elastically pressing portion elastically pressed against a tubular internal surface of the exterior body.

An interior body is housed in a tubular exterior body. The interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together. Elastic arms are disposed on the movable portion so as to extend downward. Each elastic arm includes, at a lower end portion, an elastically pressing portion, which is elastically pressed against a tubular internal surface of the exterior body. Since the elastically pressing portion is elastically pressed against the exterior body, electric signals are more likely to flow between the movable portion and the exterior body and more likely to be prevented from leaking to the spring portion.

The present invention relates to a board connection assembly being characterized by comprising: a board connection pin for transmitting a signal; a dielectric portion having a first insertion hole into which the board connection pin is inserted; a housing having a trench into which a part of the dielectric portion is inserted and a second insertion hole into which the board connection pin is inserted; and a ground contact portion disposed between the housing and the dielectric portion to contact a ground electrode, wherein the ground contact portion has one side inserted into the trench so as to contact one surface of the trench, and the other side formed to be grounded with the ground electrode, and the height of the housing is configured to be smaller than the width of the housing.

A RFID reader magnetically attachable to a smart phone includes a circuitry adaptor and a RFID access device. The circuitry adaptor is plugged into a USB connector of the smart phone. The RFID access device is magnetically and detachably connected to the circuitry adaptor, so that electricity and signals from the smart phone are transmitted to the RFID access device, and RFID tag signals picked up by the RFID access device are transmitted to the smart phone. When the RFID access device undergoes external impact, the circuitry adaptor and the RFID access device are detached from each other without damaging the USB connectors.

An electrical connector assembly including a first connector and a second connector to be mated with each other is provided. The first connector includes a first body, and at least one first terminal and multiple second terminals disposed therein. The second terminals are symmetrically arranged at opposite sides of the first terminal. The second connector includes a second body, at least one third terminal movably disposed in the second body, multiple fourth terminals disposed in the second body and symmetrically arranged at opposite sides of the third terminal, and a driving module electrically connected to at least one of the fourth terminals and structurally connected to the third terminal. In the mating process of the first and second connector, the second terminals and the fourth terminals are electrically connected firstly, to trigger the driving module to move the third terminal to be structurally and electrically connected to the first terminal.
