Abstract
The invention relates to an electric terminal, which comprises: insulated main body, and several conductive terminals inside the main body, wherein said conductive terminal has the first group of conductive terminals and second group of conductive terminals; the first and second groups are made from different materials, to reduce the resistance difference between conductive terminals. Compared with present technique, the invention can improve the electric property.
Description
[technical field]
The present invention relates to a kind of electric connector.
[background technology]
The electric connector of prior art, it comprise the insulating body that is provided with some openings and terminal containing slot, some be installed in the opening in cover shell, some conducting terminals that is inserted in terminal containing slot, and be coated on the outer outer shell that covers of insulating body.In order to prevent between the terminals of adjacent to cause short circuit,, be typically provided with a back plug also for terminal tail end good location is inserted circuit board to aim at owing to self-deformation or foreign matter fall into.Yet this electric connector is generally alloyed copper because its conducting terminal is generally same material and makes, and as phosphor-copper, and because the length of its conducting terminal is inequality.Like this, the resistance value difference that this can cause each conducting terminal influences the synchronous transmission of electronic signal, is unfavorable for improving electric property.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[summary of the invention]
The object of the present invention is to provide a kind of novel electric connector, the impedance contrast that it can reduce between the conducting terminal helps improving electric property.
For achieving the above object, electric connector of the present invention, comprise insulating body and some conducting terminals that is located in the insulating body, described conducting terminal comprises first group of conducting terminal and second group of conducting terminal, described first group of conducting terminal and second group of conducting terminal are that different materials is made, and it can reduce the impedance contrast between the described conducting terminal.
Compared with prior art, electric connector of the present invention, because the material of conducting terminal is inequality, the impedance contrast that it can reduce between the conducting terminal helps improving electric property.
[description of drawings]
Fig. 1 is the three-dimensional combination figure of electric connector of the present invention.
Fig. 2 is the cutaway view of electric connector shown in Figure 1.
Fig. 3 is the three-dimensional exploded view of electric connector of the present invention.
[embodiment]
See also Fig. 1 to Fig. 3, electric connector of the present invention comprise the insulating body 1 that is provided with some openings 11 and terminal containing slot 12, some be installed in the opening 11 in cover shell 2, some conducting terminals 3 that is inserted in terminal containing slot 12, be coated on the outer of insulating body 1 and cover shell 4, and the back plug 5 that is installed in insulating body 1 rear portion.
Described conducting terminal 3 comprises first group of conducting terminal 30 and second group of conducting terminal 31, described first group of conducting terminal 30 and second group of conducting terminal 31 are made for different materials, wherein, the conductance of described first group of conducting terminal 30 is higher than second group of conducting terminal 31, first group of conducting terminal 30 made for ambrose alloy, second group of conducting terminal 31 made for phosphor-copper, and the conductance of described two kinds of materials is all higher.The shape of described conducting terminal 3 is identical, comprise holding parts 32, and the contact site 33 that can be connected and can be connected to the junction 34 of circuit board (not icon) with external electronic components, the length of described first group of conducting terminal 30 is greater than second group of conducting terminal 31, but because the conductance of described first group of conducting terminal 30 is higher than second group of conducting terminal 31, therefore, its resistance value is more or less the same, substantially can realize the synchronous transmission of electronic signal, help improving electric property.And the shape of the contact site 33 of described conducting terminal 3 is identical.
This back plug 5 is processed by plastic material, and it is provided with a main body 50, and this main body 50 is provided with some holes 51 that vertical direction connects that are, to accommodate the afterbody of corresponding terminal 3.These main body 50 both sides stretch out and are provided with raised line 52, and this raised line 52 extends upward and form two arms 53, and this two arm 53 is provided with projection 54 in both sides near terminal position.This insulating body rear portion is provided with two pairs of projections (not icon) near the rear surface, preventing that assembling back, back plug 5 outwards withdraws from, is respectively equipped with the groove (not icon) of level at 1 liang of medial surface of insulating body, with after beyond the Great Wall projection 54 match.During assembling, this back plug 5 inserts along projection is inboard with two arms 53, when being inserted into the precalculated position, this projection snaps in the groove, thereby insulating body and back plug are fixed, with fixing described conducting terminal 3, again will in cover shell 2 and be installed in the opening 11, at last, will cover shell 4 outward is coated on the insulating body 1.
Electric connector of the present invention, because the material difference of its conducting terminal, the impedance contrast that it can reduce between the conducting terminal helps improving electric property.
