Description
Technical field
The present invention relates to be equipped on information terminal machine such as mobile phone, be used for the coaxial connector of the belt switch of its output input part.
Background technology
The socket 80 of the coaxial connector of traditional belt switch has insulation shell 81 shown in figure 32, is formed with fitting projection 82 on this insulation shell 81.Central part in this fitting projection 82 is provided with terminal installing hole portion 83, is equipped with in this terminal installing hole portion 83: splicing ear 84, have the switched terminal 85 of contact site 85a, the 84a of the circuit-opening contact portion contact switched terminal 85 of splicing ear 84.External conductor (clamshell) 86 is installed on insulation shell 81, and the cylindrical portion 87 of this external conductor 86 is covered with fitting projection 82.
The socket 80 of Gou Chenging is installed on the printed circuit board (PCB) (not having icon) by this way, and splicing ear 84, switched terminal 85, external conductor 86 are welded on the conductive pattern (not having icon) of printed circuit board (PCB) at leading part 84b, 85b, 86b respectively.
The plug 90 that is connected in socket 80 has insulation shell 91, central part at this insulation shell 91 is provided with: the inner conductor 93 with the 93a of contact portion, on insulation shell 91, to be provided with the cylindrical portion 94a of external conductor 94 around the mode of inner conductor 93, chimeric recess 92 is made in the inside of this cylindrical portion 94a.
When the mode that is inserted into the chimeric recess 92 of plug 90 with the fitting projection 82 with socket 80 was inserted plug 90, the 93a of contact portion of inner conductor 93 can contact the contact site 85a of switched terminal 85, made the inner conductor 93 and switched terminal 85 conductings of plug 90.At this moment, the cylindrical portion 87 of the cylindrical portion 94a of the external conductor 94 of plug 90 contact external conductor 86 and conducting mutually.The cylindrical portion 87 of the cylindrical portion 94a of plug 90 and socket 80 is chimeric and contact, and thus plug 90 is connected with socket 80.
On the other hand, switched terminal 85 is because the contact site 85a of the 93a of the contact portion contact switched terminal 85 of inner conductor 93 and deflection, and completely cut off contacting between the 84a of circuit-opening contact portion with splicing ear 84.
When pulling out plug 90, switched terminal 85 is owing to the elasticity of itself is replied free state, once more with the 84a of circuit-opening contact portion Elastic Contact.
So this coaxial connector switches to splicing ear 84 (with reference to patent documentation 1) owing to the insertion of plug 90 makes the connection of switched terminal 85 switch to plug 90 from splicing ear 84 once more owing to pull out plug 90.
And also just like Figure 33 and traditional coaxial connector shown in Figure 34.On the socket 104 of this coaxial connector, external conductor 100 has external conductor main body 100A, this external conductor main body 100A have be used for covering inner conductor 101 around the cylindrical portion 100a of tubular, at the rear portion of the inverted u-shaped of this external conductor main body 100A, connecting the back side shielding part 100b of the leading part 101a side that is used for covering inner conductor 101 via kink 100c.
Because the cylindrical portion (all not having figure to section out) of the external conductor of plug and chimeric contact of cylindrical portion 100a of the external conductor 100 of socket 104, be connected (with reference to the patent documentation 2) of the external conductor that makes plug and the external conductor 100 of socket 104.
