Description
Technical field
This creation relates to a kind of electric connector, relate in particular to the electric connector of the one-body molded terminal of a kind of tool, its terminal is formed in one to reduce impedance, and terminal itself has favorable elasticity provides stable Telescopic, and terminal can keep linear extendible and avoid along nonlinear irregular path flexible and cause terminal distortion or damage.
Background technology
Electric connector is spare part common in electronic installation, can supplied for electronic device and other electronic installations be electrically connected and fetch transmission information or power supply.
One spring battery connector is all installed in the battery chamber in the portable electronic equipments such as existing Smartphone, and for example TaiWan, China discloses application for a patent for invention case, TaiWan, China certificate number M418465 new patent and TaiWan, China certificate number M462453 new patent those disclosed herein No. 201332225.Spring battery connector has an insulating body and plural number is arranged on the terminal assemblies in insulating body.Each terminal assemblies is multi-piece type and have respectively a solder terminal, contact terminal and spring, contact terminal is bullet shaped and can be for contacting the metallic contact of battery, spring is arranged between solder terminal and contact terminal, can force contact terminal to stretch out outside insulating body.Yet, the part of terminal assemblies is too much, cause assembly program complicated, and between part, easily produce dislocation and cause contact terminal to block and be difficult to normal stretching, in addition, when transmitting large electric current between battery and spring electric connector, owing to can may causing because contact area is too small impedance to raise between the parts such as adjacent solder terminal, contact terminal and spring, terminal assemblies cannot be passed through for large electric current smoothly, even cause the problems such as overheating fault.
Please refer to Fig. 7, TaiWan, China certificate number M346937 new patent has disclosed a kind of connector with one-body molded terminal, and this connector comprises an insulating body 70, a shielding case 80 and plural terminals 90.On insulating body 70, be formed with plural fixing hole 71.Shielding case is coated on outside insulating body 80.Terminal 90 is arranged on respectively in fixing hole 71, and each terminal 90 is formed in one, and is arranged on insulating body 70 and has a weld part 91, a spring portion 92 and a contact site 93.Spring portion 92 is horizontal serpentine shape, be formed on weld part 91 and have one with the linkage section 921 and two of terminal 90 axially parallels be formed on linkage section 921 two ends and can be relative the elastic arm 922 of linkage section 921 bendings, contact site 93 is V-shaped and be formed on spring portion 92 front ends and be connected with an elastic arm 922 wherein.Yet, the spring portion 92 of terminal 90 is when being subject to force compresses, relative linkage section 921 pivotables of elastic arm 922 meeting, make when contact site 93 is past to be inside contracted axially to produce and to swing by relative terminal 90, cause contact site 93 to inside contract along nonlinear crooked path, cause contact site 93 easily to block, V-arrangement contact site 93 cannot contact by face with rectangle fixing hole 71 inwalls of insulating body 70, therefore 71 pairs of contact sites 93 of fixing hole cannot produce guide function, therefore contact site 93 easily crookedly when flexible even blocks fixing hole 71 is interior, cause terminal cannot stablize contact battery contact and cause signal and electric power transfer bad.In addition, the linkage section of above-mentioned spring portion, for the straightway with axially parallel cannot compress, causes spring portion 92 compression effectiveness poor.
