Description
【Technical field】
A kind of a kind of the present invention relates to electric connector, more particularly to electric connector with light-guiding pillar.
【Background technology】
The structure that light emitting diode (LED) is engaged with light-guiding pillar (Light pipe) used in existing RJ45 electric connectors is used for the network communication state of indicating electrical connector.Existing light-guiding pillar be using Merlon (Polycarbonate,
PC) material is made, the heat distortion temperature of PC materials is 135 DEG C or so, as existing RJ45 electric connector weldings to outside mainboard (mother board) use wave-soldering ((Wave Soldering), this welding process RJ45 electric connector is located at outside tin liquor groove, and what will not produce on the light-guiding pillar using PC materials affects.
But, part mainboard manufacturer requires that infrared ray Reflow Soldering (IR reflow) high temperature furnace crossed together with SMT parts by RJ45 electric connectors at present, so RJ45 electric connectors have to the high temperature resistant demand for meeting reflow, i.e. RJ45 electric connectors and need high temperature resistant to 260 °C or so.As the light-guiding pillar heat-resisting ability of PC materials only has 135 DEG C or so, so RJ45 electric connectors cannot be required by the infrared ray of mainboard manufacturer backflow soldering high temperature resistant at present.
【Content of the invention】
The technical problem to be solved is：A kind of electric connector with light-guiding pillar is provided, its light-guiding pillar is resistant to high temperature reflux weldering.
For solving above-mentioned technical problem, the technical scheme is that：
A kind of electric connector, which includes insulating body and the light-guiding pillar being coated in insulating body, the insulating body has interface and along the longitudinal direction through the mounting groove of interface, the light-guiding pillar is installed on mounting groove, the light-guiding pillar has leading section and rearward end, interface of the leading section adjacent to insulating body, the rearward end near a light source and can be conducted to front end face the light that light source is launched to recognize, the material of wherein described light-guiding pillar is polyethersulfone resin.
Compared with prior art, the material of light-guiding pillar of the present invention is polyethersulfone resin (Polyethersulfone, PES), and which can bear the high temperature of Reflow Soldering.High temperature resistant reaches 260 DEG C or so of transparent plastic currently without discovery, PES heat deformations temperature degree is at 200～220 DEG C or so, and due to the plastic cement color of PES injection moldings partially yellow, so PES plastics be used for make in transparent light-guiding pillar technical staff's limit of consideration not in the field of business.But, the applicant breaks technology prejudice and is surprised to find after many experiments, although the plastic cement color of PES injection moldings is a little partially yellow, but have no effect on the printing opacity of light-guiding pillar, and although PES plastic deformations temperature is 200～220 DEG C or so, but as which is coated on the inside of insulating body, be still able to bear in welding high temperature furnace 260 DEG C or so of high temperature and indeformable.
