The afterbody of described connecting needle is provided with one the installation portion that inner shrapnel is used is installed.
Described inner shrapnel mid portion is concave surface arc structure, and inner shrapnel two end portions is band square groove circular tube structure.
Described three-jaw wire clamp comprises wire clamp front portion and wire clamp rear portion, and wire clamp front portion is tube-shaped structure, and wire clamp rear portion is three sharp claw structures.
Described wire clamp front portion is provided with a back-off, and back-off is connected with splicing ear.
Described shell comprises thread endoporus and rear end wire hole; Wherein, between thread endoporus and rear end wire hole, be provided with a gradient.
The utility model, with respect to prior art, has following advantage and effect:
1, the utility model has adopted and has comprised splicing ear, three-jaw wire clamp, the first insulating gum cover, the second insulating gum cover, connecting needle, inner shrapnel and shell; Wherein, three-jaw wire clamp is set in splicing ear, the first insulating gum cover is located in three-jaw wire clamp, connecting needle is inserted in the first insulating gum cover, connecting needle afterbody arranges inner shrapnel, and connecting needle is through the second insulating gum cover, and the second insulating gum cover and the extruding of splicing ear inwall are closely, splicing ear is connected with outer casing screw, has simple in structure, low cost, simple and convenient assembly, quality of connection is good and without features such as professional tool assemblings.
2, the afterbody of the connecting needle in the utility model is provided with one the installation portion that inner shrapnel is used is installed, and convenient installation, enhances productivity.
3, the inner shrapnel mid portion in the utility model is concave surface arc structure, and inner shrapnel two end portions is band square groove circular tube structure, when the heart yearn of cable insert with connecting needle in inner shrapnel time, just can reach the effect of close contact.
4, the shell in the utility model comprises thread endoporus and rear end wire hole; Wherein, between thread endoporus and rear end wire hole, be provided with a gradient, thereby the sharp claw that reaches three-jaw wire clamp rear portion is subject to the extruding force of shell, thrust cable, and with cable sheath in shielding conductor close contact.

Embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
embodiment:
As shown in Figure 1 and 2, a kind of accurate electric connector with inner shrapnel card wire structure, comprises splicing ear 1, three-jaw wire clamp 2, the first insulating gum cover 3, the second insulating gum cover 4, connecting needle 5, inner shrapnel 6 and shell 7; Wherein, the interior three-jaw wire clamp 2 that arranges of splicing ear 1, the first insulating gum cover 3 is located in three-jaw wire clamp 2, connecting needle 5 is inserted in the first insulating gum cover 3, connecting needle 5 afterbodys arrange inner shrapnel 6, connecting needle 5 is tight with splicing ear 1 inwall extruding through the second insulating gum cover 4, the second insulating gum covers 4, and splicing ear 1 is threaded with shell 7.
Connecting needle 5 afterbodys in the present embodiment are provided with an installation portion 8 that inner shrapnel 3 use are installed, the round external diameter of inner shrapnel 6 is more bigger than the internal diameter of installation portion 8, inner shrapnel 6 mid portions are concave surface arc structure, inner shrapnel 6 two end portions are band square groove circular tube structure, three-jaw wire clamp 2 comprises wire clamp front portion and wire clamp rear portion, wire clamp front portion is tube-shaped structure, wire clamp rear portion is three sharp claw structures, wire clamp front portion is provided with a back-off 9, back-off 9 is connected with splicing ear 1, the effect of back-off 9 is fixedly in three-jaw wire clamp 2 Snap joint terminals 1, can not exit, reach the effect that clamps cable and can be not loosening, shell 7 comprises thread endoporus and rear end wire hole, wherein, between thread endoporus and rear end wire hole, be provided with a gradient, while locking to reach splicing ear 1, the three-jaw wire clamp 2 of Snap joint terminal 1 inside can draw sharp claw in along gradient, thereby the sharp claw that reaches three-jaw wire clamp 2 rear portions is subject to the extruding force of shell and thrusts cable, and with cable sheath in shielding conductor close contact.
During concrete operations, because connecting needle 5 afterbodys have inner shrapnel 6, in the time of can reaching the insertion of cable heart yearn, contact and do not need the actions such as welding to be connected with connecting needle 5 well.And splicing ear 1 rear end has three-jaw wire clamp 2, can when locking with the thread of shell 7, splicing ear 2 be subject to the extruding force of shell, thereby draw three sharp claws in, sandwich in cable the object that reaches fixed cable and contact with shielding conductor.Because when this series of actions can be locked shell 7 by splicing ear 1, reach voluntarily the assembly and connection of socket and cable, thus manufacture efficiency can be improved, and do not need yet light assembly and connection of professional tool.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute mode, within being included in protection range of the present utility model.
