As a kind of preferred version: the annular socket part of described plural conductive terminal is coated with a plastic casing.
As a kind of preferred version: described housing comprises main body and lower cover, this main body has a host cavity, this host cavity is provided with an installing port, described circuit board is placed in this host cavity by installing port, this lower cover and main body are affixed and be encapsulated in the installing port position of host cavity, are provided with a spacing hole corresponding with above-mentioned jack in main body one side; The link of described audio jack has diameter greater than the boss that support to end of spacing hole, and after the link of audio jack inserted in the jack, the inserted terminal of audio jack stretched out outside by spacing hole, and above-mentioned supporting ended boss and be blocked in the spacing hole inboard.
As a kind of preferred version: described housing also is provided with a loam cake, and this main body top offers a form that is used for observation audio jack and jack connection state, and described loam cake is fixed in the main body top and seals this form.
As a kind of preferred version: described spacing hole is protruded out to its outside one by housing and forms.
As a kind of preferred version: described pin has the sidewall that two arcs arch upward, and is surrounded by one by this two side and can supplies elastically-deformable hollow-out parts.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, by row's conducting terminal is set, form the jack of pegging graft for audio jack on the card reader circuit board, audio jack close-fit and jack are electrically connected, avoided being connected by the welding electric wire between conventional audio plug and the circuit board, complex process, assembling is inconvenient, and cause easily that bonding wire comes off in the production run, cause the underproof phenomenon of product.By this, the plug of this card reader and the connected mode of circuit board make product manufacture simple, and be easy to assembly, improved card reader production efficiency and audio jack and docked stability with circuit board.
For more clearly setting forth architectural feature of the present utility model and effect, be described in detail below in conjunction with accompanying drawing and specific embodiment.
