An electronic card connector, defining an insertion direction, an ejection direction, and a transverse direction perpendicular to the insertion direction, includes an insulative housing and a number of terminals retained in the insulative housing. The terminals include a row of first contacts disposed along the insertion direction. Each first contact has a first affixed portion and a first contacting portion located at a peak therein. Each of the first contacts extends along the transverse direction. The first contacting portions of the neighboring first contacts are located offset along the insertion direction. The first contacting portions and associated first affixed portions of the first contacts are distanced differently in the transverse direction.

A button structure and a terminal using the same are provided. The button structure includes a connecting element, a press element, and at least one elastic element connected to the connecting element and the press element. The elastic element is configured to provide a restoring force after the press element is pressed toward the connecting element. The connecting element is provided with an instruction transmission port and at least one of a current transmission port and a data transmission port. The press element is provided with an instruction triggering port and at least one of a current transmission pin and a data transmission pin. The current transmission pin is electrically connected to the current transmission port to output or input current. The data transmission pin is electrically connected to the data transmission port to output or input data.

Provided is a matable electrical connection structure including a female connection member and a male connection member respectively including a plurality of first connection portions and a plurality of second connection portions, and a plurality of matable connection portions configured to detachably couple the female connection member and the male connection member, and respectively and electrically connect the plurality of first connection portions to the plurality of second connection portions, and the matable connection portions include inner conductive materials respectively and electrically connected to the plurality of first connection portions and provided on inner walls of a plurality of insertion holes formed in the female connection member, columns respectively and electrically connected to the plurality of second connection portions and configured to protrude from the male connection member to be inserted into the insertion hole, and elastic fins configured to extend outside the column to elastically contact the inner conductive material, and at least one of the female connection member and the male connection member is divided into a plurality of areas, and the plurality of matable connection portions are disposed to form a group in each of the areas.

Provided is a method of manufacturing an electrical connection structure which includes a female connection structure having an inner conductive material inside an insertion hole of a female connection member, and a male connection structure having a conductive column configured to be inserted into and fixed to the insertion hole to be in contact with the inner conductive material, and formed to protrude from a male connection member. The method includes preparing insulating members used for the female connection member and the male connection member, and forming the inner conductive material and the column by patterning a conductive material on each of the insulating member using a photolithography process.

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.

In a connector, a contact includes: a first connection portion and a second connection portion that are retained between a first insulator and a second insulator and face each other; and a pressing force receiving portion that makes contact with the second insulator and receives a pressing force from the second insulator to thereby press the first connection portion against the second connection portion. A connection object is sandwiched between the first connection portion and the second connection portion, and at least one of the first connection portion and the second connection portion makes contact with a flexible conductor of the connection object, whereby the contact is electrically connected to the flexible conductor of the connection object.

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.

A card edge connector includes: a housing including a board accommodation space and a connection terminal including a resilient contact piece configured to contact a circuit board inserted into the board accommodation space, the connection terminal being mounted into the housing. The connection terminal is movable between a connection position where the resilient contact piece is in contact with a surface of the circuit board and a retraction position where the resilient contact piece is separated from the circuit board. A first interference preventing portion and a second interference preventing portion are formed between a moving path of the resilient contact piece and the board accommodation space. The first interference preventing portion and the second interference preventing portion restrict the interference of the resilient contact piece and an inserting end part of the circuit board inserted into the board accommodation space in a moving process of the connection terminal.
