Description
[technical field]
The present invention relates generally to a kind of electric connector, refers to a kind of socket element (as, standard USB socket connector) of both can having docked especially, can firmly dock the plug element electric connector of (as, memory card) again, and the insertion method of this electric connector.
[background technology]
USB (Universal Serial Bus, USB) but be a kind of electric connector of transmit high-speed signals, be widely used at present and connect various electronics main frames and external equipment.Along with popularizing of USB connector, it is that further research and develop on the basis that the insider begins with original USB standard, design various have expanding function, the transmission standard USB interface signal of telecommunication and the extra electric connectors of the signal of telecommunication (as the memory card signal of telecommunication) simultaneously.
Standard USB connector 100 (seeing also Fig. 1,2), usually have an insulating body 110, this insulating body 110 comprises a base portion 111, this base portion 111 extends to form a hyoplastron 112 forward, a plurality of terminal channels 113 extend through base portion 111 along the butt joint direction, and extend hyoplastron 112 1 surfaces, a plurality of conducting terminals 120 correspondence respectively are arranged at described terminal channel 113, and each conducting terminal 120 has the fixed part 121 of a contact site 123, an afterbody 122 and a connection contact site 123 and afterbody 122.
Present memory card 4 (seeing also Fig. 3), as Micard, it generally has an inserted terminal (front end) 41 and an opposite end (rear end) 42, one first insulating surface (front) 43 and one second insulating surface (reverse side) 44, this first insulating surface 43 is provided with one first interface 45 near inserted terminal 41 places, this first interface 45 can be the USB interface, and this first interface 45 has a plurality of first contact terminals 450 that set in a row.In addition, also can be provided with one second interface 46 adjacent on this first insulating surface 43 with this first interface 45, this second interface 46 has a plurality of second contact terminals 460 that set in a row, this first insulating surface 43 also can be provided with one the 3rd interface, 47, the three interfaces 47 near 42 places, opposite end and have a plurality of the 3rd contact terminals 470 that set in a row.Certainly, also can be provided with the interface of other type on this first insulating surface 43.And second insulating surface 44 of this memory card 4 generally is not provided with interface, and described second insulating surface, 44 both side edges are concaved with a depressed part 440 respectively, and described depressed part 440 forms a step surface with this second insulating surface 44 respectively.
When being arranged, the memory card electric connector (do not see also Fig. 2), all adopt memory card 4 is directly inserted traditional USB connector 100, make contact site 123 corresponding the connecting of each first contact terminal 450 and each conducting terminal 120 of first interface 45 of described memory card 4, to realize electric connection.So,, can occur rocking, and meet other object easily when moving, make memory card 4 and memory card electric connector 100 sustain damage because of memory card 4 protrusion amounts are too big.
For solving foregoing problems, the electric connector 200 (seeing also Fig. 4) that occurs a kind of improvement at present, it is on the basis of traditional USB connector 100, the length of base portion 111 is increased, and base portion 111 is extended the one side that is provided with hyoplastron 112 slot 114 that sets to the concave, extending a side that is provided with terminal channel 113 on these slot 114 bottoms and this hyoplastron 112 roughly maintains an equal level, and each conducting terminal 120 also has preceding contact site 123 and back contact site 124, can be placed in the part that terminal channel 113 is positioned at the part of hyoplastron 112 and is positioned at slot 114 bottoms respectively.The electric connector 200 of this improvement makes that can contact golden finger when memory card 4 deeply inserts produces signal and connect, and memory card 4 protrusion amounts are very little, can not occur rocking, and also can not meet other object easily when moving.But when inserting because of memory card 4, each first contact terminal 450 of its first interface 45 will at first can corresponding touch the preceding contact site 123 of each conducting terminal 120, the back contact site 124 that is inserted into behind the position just with each conducting terminal 120 firmly connects, so, in the memory card 4 grafting processes, of short duration conducting can appear, then occur of short duration non-conduction, and then just produce stable electrically conducting, so, may cause the damage of system, memory card; Again because of not only interface of memory card 4 surfaces, after memory card 4 is inserted into the position, the preceding contact site 123 of described conducting terminal 120 also may contact with the contact terminal (as second contact terminal 460 of second interface 46) of other interface on memory card 4 surfaces, the signal that transmits during because of memory card 4 each interface conducting or the voltage difference of carrying, not specific conducting will be produced, and cause the confusion of signal transmission, and then cause the damage of system, memory card.
Therefore, be necessary to design the insertion method of a kind of new electric connector and this electric connector to solve foregoing problems.
[summary of the invention]
The object of the present invention is to provide a kind of both can dock a socket element (as, standard USB socket connector), can firmly dock a plug element (as, memory card) again, and the electric connector of stable signal transmission when the banjo element, and the insertion method of this electric connector.
The present invention's electric connector, comprise: an insulating body, it is provided with a main part, described main part front end is arranged with to the back-end and forms one first receiving space, described main part is provided with a plurality of spaced the first terminal passages in the end face extension of first receiving space, described main part front end is provided with one second receiving space, described second receiving space is connected with first receiving space, the front end face of described main part extends forward and is provided with a hyoplastron, method second receiving space is positioned at the top of hyoplastron, this hyoplastron has a working face, extends to be provided with a plurality of spaced second terminal channels on described working face; A plurality of first conducting terminals, correspondence is contained in the above-mentioned the first terminal passage respectively; A plurality of second conducting terminals, correspondence is contained in above-mentioned second terminal channel respectively.
