The first terminal 3 (being center terminal) is contained in first accepting groove 181 of insulating body 1, is cylindric substantially.This first terminal 3 comprises the base portion 30 that is column, also is the contact site 31 of column and by the extended holding parts 32 of base portion 30 other ends by base portion 30 1 ends are extended.Contact site 31 is suspended in the host cavity 17 and can electrically connects mutually with butt connector, and the area of section of this contact site 31 is less than the area of section of base portion 30.Base portion 30 and holding parts 32 are immobilizated in first accepting groove 181, and holding parts 32 comprises first, second fixing that extends respectively downwards
321,322.First, second fixing
321, be respectively equipped with salient point 323 with 181 interferences of first accepting groove on 322, wherein first fixing
321 ends are provided with first hangnail, 324, the second holding parts 322 that cooperate with 181 interferences of first accepting groove and extend first accepting groove 181 and outwards vertically be bent to form first weld part 325.
Earth terminal 2 is assembled in the resettlement section 19 of insulating body 1, by
The shape metal stamping is bent to form.This earth terminal 2 comprises base portion 20 that fits in roof 191 and the holding parts 21 that is extended and fitted in respectively left and right sides sidewall 192,193 by base portion 20 two ends vertically downward.Holding parts 21 is provided with button and holds hole 211, and left and right sides sidewall 192,193 is provided with detaining and holds the holding part 194 that matches in hole 211, and earth terminal 2 is held hole 211 and is immobilizated on the insulating body 1 with cooperating of holding part 194 by buckleing.The 3rd weld part 212 is extended in the terminal outwards bending of holding parts 21.The extension 23 that described base portion 20 is provided with the elastic contact arm 22 that extends to docking section 16 forward and extends back.The upper wall 10 of insulating body 1 is provided with the groove 101 that matches with this extension 23, with location and fixing earth terminal 2.The centre position of described roof 191 offers an opening 195 that extends to docking section 16, and this opening 195 is connected with host cavity 17 and accommodates elastic contact arm 22, and elastic contact arm 22 is provided with and bends the contact site 221 that extends in the host cavity 17.Be respectively equipped with a breach 201 on the base portion 20 in the both sides of elastic contact arm 22, thereby increase its elasticity with the length that increases elastic contact arm 22.
