Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

[embodiment]

Refer to Fig. 1 to 6, wire and cable connector 100 of the present invention comprises insulating body 2, be immobilizated in the center terminal 3 of this insulating body 2, be positioned at center terminal 3 one sides hold terminal 5 outward, connect the cable 4 of described center terminal 3 and take shape in stress relief element 6 on cable 4 and the insulation shell 7 of coated insulation body 2, stress relief element 6.

Insulating body 2 comprises body 21 and the extension 22 certainly extending before these body 21 1 side direction, and this extension 22 has inner surface 221.Insulating body 2 has relative front end face 24, rear end face 25 and groove 23, and this groove 23 runs through the rear end face 25 of insulating body 2 and the inner surface 221 of extension 22, holds terminal 5 outward and is immobilizated in this groove 23.Insulating body 2 is one-body molded with center terminal 3, holds terminal 5 outward and is assembled in insulating body 2 from the rear end face 25 of insulating body 2.

Center terminal 3 comprises the link 32 that 31 rear ends, 31Ji Zi butt end, cylindrical butt end extend back and form, and the diameter of section of butt end 31 is greater than the diameter of section of link 32, and link 32 outer surfaces are provided with boss 33.It is more firm that this structure makes center terminal 3 coordinate with insulating body 2.The body 21 of insulating body 2 is flat, and center terminal 3 is immobilizated in body 21 1 sides, and extension 22 extends to form forward from the relative opposite side of body 21.

Refer to Fig. 2 and 3, hold terminal 5 outward and be stamped to form by a sheet metal, the connecting portion 52 that it comprises the holding section 51 of the front end face 24 that is stretched on insulating body 2 and is stretched on relative rear end face 25, this connecting portion 52 is connected with the ground plane 42 of cable 4.Hold terminal 5 outward and also comprise that interference is immobilizated in the holding parts 53 in insulating body 2, holding section 51 is connected with holding parts 53 one end, connecting portion 52 is connected with holding parts 53 other ends by a kink 54, described kink 54 is towards center terminal 3 one lateral bucklings, arranging of this kink 54 convenient is pressed in the groove 23 of insulating body holding terminal outward, is also easier to hold the connecting portion 52 of terminal 5 outward and the ground plane 42 of cable 4 is connected simultaneously.The holding section 51 of holding terminal 5 outward protrudes from the inner surface of extension 22, and when butt connector (not shown) docks with this connector 100, holding section 51 has elasticity, and the docking section that supports butt connector makes two connectors connections more firm, is not easy to come off.Hold terminal 5 outward and be first connected with cable 4, soon connecting portion 52 is coated and is connected in the ground plane 42 of cable 4, and then by outer the holding in the groove 23 that terminal is assembled in insulating body 2 from back to front that is connected with cable 4.
