Detailed description of the invention
Scene is shown in enforcement such as Fig. 1～7 of wiring connector: includes the metal shell 1 that front end is inserted terminal, sets in metal shell
It is equipped with axially along the axially extending installing hole of fore-and-aft direction, axially mounted hole is provided with the insulator 8 being built-in with contact 4, connects
It is provided with the core perforation 9 installed for respective cable core in contact element, the hole wall of core perforation is provided with screw perforation 12, spiral shell
Nail perforation is coated with for cable core being press-fited the line pressing bolt 3 being fixed in corresponding core perforation.It is provided with on insulator
The platform 11 being connected with insulator outer peripheral face by indent step, platform is provided with the insulator perforation corresponding with screw perforation
13, define a radially assemblage gap between table top and the hole wall in axially mounted hole of platform, this radial direction assemblage gap passes through
Fixed structure is fixedly installed insulation anti-falling piece, and insulation anti-falling piece is an insulating press boards 6, insulating press boards is provided with for line ball spiral shell
Nail, along the movable chamber of the axially reciprocating of corresponding screw perforation, insulating press boards is additionally provided with radial protrusion 10, on metal shell
Being provided with the draw-in groove 2 of the plug-in mounting that coincide for radial protrusion, the forward and backward side channel wall of draw-in groove constitutes block axial with insulating press boards and coordinates
And limit the axial Stop structure that insulating press boards moves axially；The circumferential both sides cell wall of draw-in groove constitutes and insulating press boards circumference block
Coordinate and limit the circumferential Stop structure that insulating press boards circumferentially rotates；The hole wall in the table top of platform and axially mounted hole constitute with absolutely
Edge pressing plate radially block coordinates and limits the radial direction Stop structure that insulating press boards moves radially, axial, circumference, radially Stop structure
Constitute described fixed structure.Be provided with on radial protrusion corresponding to screw perforation position for corresponding screwdriver through rear to pressure
Line screw applies the spiral shell tool bore 5 of moment of torsion, and the aperture of spiral shell tool bore is less than the external diameter of the screw cap of line pressing bolt, the endoporus edge of screw hole
Constitute for coordinating with line pressing bolt block and to limit line pressing bolt anti-towards the screw moving the limit away from corresponding screw perforation direction
De-structure.The jump ring 7 realizing the axial anticreep of insulator it is provided with between rear end and the insulator of metal shell.
The assembling process of wiring connector is done at this scene: be first assemblied in metal shell by insulating press boards, makes the footpath on insulating press boards
In the draw-in groove that projection is plugged on metal shell, being then assemblied on insulator by contact, line pressing bolt is also loaded onto correspondence
In screw perforation, then drop in the axially mounted hole that this global facility of contact, line pressing bolt and insulator loads metal shell,
Then by jump ring, insulator is limited on metal shell.Insulator can also be to insulating press boards axial pressure, and this also just means
Draw-in groove, insulator axial limiting dual to insulating press boards, platform is set on insulator, contribute to the shape of radially assemblage gap
Becoming and do not increase the radial dimension of metal shell, platform coordinates with insulating press boards spline simultaneously, and draw-in groove, platform are double to insulating press boards
Weight circumference is spacing, it is ensured that insulating press boards fixed；Platform structure also makes insulator perforation easy to process simultaneously.
In other embodiments of the invention: screw disconnecting prevention structure can also be by the block in the cavity wall being arranged at movable chamber or annular block
Step is constituted, and now the aperture of spiral shell tool bore can be not less than the external diameter of the screw cap of line pressing bolt；When metal shell rear end does not extends
Time on rear side of insulating press boards, the draw-in groove on metal shell can not also set, now spacing to insulating press boards circumference circumferential block knot
Structure can be separately formed by platform, can be by corresponding forward and backward insulator structure to the axial Stop structure of insulating press boards axial limiting
Become；Movable chamber can also be arranged on insulator or between insulator and insulating press boards；Fixed structure can also be for being arranged at insulation
Screw fixed structure between pressing plate and insulator or glue-filling solid fixed structure；Insulation anti-falling piece can also is that block shape structure or framework knot
Structure.
