Abstract
A movable terminal, a coaxial connector, and a communication apparatus all have a greatly reduced size and height. The coaxial connector includes an insulating case made from a synthetic resin and divided into a lower insulating case and an upper insulating case, a metallic fixed terminal, a movable terminal, and an external terminal (external conductor). The movable terminal is formed by punching a stainless steel plate made of SUS 301 having a spring property so as to have a predetermined shape and bending it. Then, on surfaces of the stainless steel (SUS 301), nickel plating films are formed and on the nickel plating films, gold is further plated so that the movable terminal has an overall thickness in the range of from about 45 μm to about 62 μm.
Claims18
A movable terminal comprising:
- a frame;
- a movable spring portion having two ends that are supported by the frame and a central portion thereof that is movable and is elastic;
- a contact portion that is integral with the movable spring portion and that is arranged to come into contact with and connect to a fixed terminal;
- a fixed portion that is integral with the frame and is arranged to be sandwiched by an upper insulating case portion and a lower insulating case portion of a coaxial connector;
- and
- a lead extending from the fixed portion;
- wherein
- the fixed portion includes at least one recess provided therein for being fitted to a leg disposed on the upper insulating case portion of the coaxial connector so as to accurately locate the movable terminal with respect to the upper insulating case portion.
A coaxial connector comprising:
- an insulating case having a recess formed therein and arranged to receive a central contact of another coaxial connector that is to be inserted therein, said insulating case includes upper and lower case portions;
- a movable terminal including:
- a frame;
- a movable spring portion having two ends that are supported by the frame and a central portion thereof that is movable and is elastic;
- a contact portion that is integral with the movable spring portion and that is arranged to come into contact with and connect to a fixed terminal;
- and
- at least one recess provided in said frame;
- wherein the movable terminal is arranged within the recess of the insulating case so as to protrude in a direction that is substantially perpendicular to the inserting direction of the central contact of the other coaxial connector, and said at least one recess is fitted to said upper case portion of said insulating case so as to accurately position the movable terminal in the insulating case;
- a fixed terminal arranged within the recess of the insulating case so as to be brought into contact with and connected to the contact portion of the movable terminal;
- and
- an external terminal attached to the outside of the insulating case and electrically connected to an external conductor of the other coaxial connector;
- wherein the contact portion of the movable terminal is arranged to be movable from a position at which the movable terminal is separated from the fixed terminal to a position at which the movable terminal is in contact with the fixed terminal in accordance with attachment and detachment of the other coaxial connector.
