Make every effort at electric device under the development trend of microminiaturization, adopt the connector volume of Low Voltage Differential also to be restricted relatively, so will make the spacing of numerous terminal connections be tending towards crowded; Yet, adopt the people to weld mutually with pairing terminal 2 respectively with the corresponding line group of the connector of Low Voltage Differential connector for the mode of welding all heart yearns 4 with line group 3 more, so not only increase the difficulty of weld job, relative heart yearn 4 and the welding quality between the terminal 2 and welding reliability also can't effectively be controlled.
The utility model content
In view of this, main purpose of the present utility model is promptly providing a kind of line group connector construction that is fit to be applied to Low Voltage Differential (LVD) especially.
Take off purpose on reaching, line group connector of the present utility model is provided with plurality of terminals at the front end of a plastic body, be provided with a substrate in the rear end that plastic body is provided with terminal relatively in addition, the end that this substrate relatively engages with plastic body be provided with some respectively with each terminal over against first contact for and the electric connection of terminal formation, it then is provided with second contact identical with first number of connections with respect to the end in addition that is provided with first contact and constitutes electric connection for the heart yearn with the line group, between each corresponding first contact and second contact and be provided with circuit in order to constitute to electrically connect, overall wire group connector can utilize the circuit of substrate to extend, and the spacing that makes each second contact is relatively greater than the spacing of each first contact.
One of effect of the present utility model, the spacing that is each second contact can reduce the welding difficulty with the line group relatively greater than the spacing of each first contact.
Two of effect of the present utility model, the spacing that is each second contact be relatively greater than the spacing of each first contact, more effectively the welding quality of control line group and weld reliability.
Three of effect of the present utility model, but be that this substrate stretches out plastic body one end relative orientation plastic body both sides relatively and protrudes an extension and grasp for the user, and using increases processing and plug convenience.

Embodiment
Characteristics of the present utility model can be consulted the detailed description of the graphic and embodiment of this case and obtained to be well understood to.
To shown in Figure 4, the utility model is applicable to that the line group connector of Low Voltage Differential (LVD) has consisted essentially of: a plastic body 10, plurality of terminals 20, and a substrate 30 as Fig. 2; Wherein:
Each terminal 20 is fixedly arranged on this plastic body 10 front ends, and the quantity of its terminal 20 and configuration specification can meet the connector specification of Low Voltage Differential; This substrate 30 is connected in this plastic body 10 rear ends, its end that relatively engages with this plastic body 10 be provided with some respectively with each terminal 20 over against first contact 31 for and terminal 20 formation electric connections, it then is provided with second contact 32 identical with first contact, 31 quantity with respect to the end in addition that is provided with first contact 31 and constitutes electric connection for the heart yearn 51 with line group 50, between each corresponding first contact 31 and second contact 32 and be provided with circuit (indicating among the figure) in order to constitute to electrically connect, the spacing that makes each second contact 32 is relatively greater than the spacing of each first contact 31.
When implementing, this substrate 30 can be made of printed circuit board (PCB), and each corresponding first contact 31, second contact 32 and be connected in circuit between first contact 31, second contact 32 (indicating among the figure) and be made of the metallic circuit layer on the printed circuit board (PCB).Moreover overall wire group connector can further be provided with the structural strength that a metal-back 40 is used increases overall wire group connector in the outside of this plastic body 10, simultaneously as the mechanical structure body that carries this substrate 30; Especially, protrude an extension 34,41 and grasp, use the convenience that increases processing and plug for the user but this substrate 30 and this metal-back 40 stretch out plastic body 10 1 end relative orientation plastic bodies 10 both sides relatively.
