Detailed description of the invention
The enforcement of electric connector is such as shown in Fig. 2 ~ 5: including metal shell 8 and be provided with the insulator 17 of contact 7, metal shell 8 has the installing hole that axis extends along the longitudinal direction.During use, insulator 17 is encased in installing hole from front to back, in installing hole, the rear side in insulator is provided with the block direction insulator installation step 6 moving the limit for limiting insulator backwards forward, in the present embodiment, insulator installation step 6 is wholely set with metal shell, in installing hole, the front side in insulator is provided with for coordinating with insulator block to limit the removable stop part 5 that insulator moves forward, and in the present embodiment, removable stop part 5 is the jump ring being installed in the jump-ring slot on installing hole hole wall.nullElectric connector also include by rear to front loading installing hole for black box friction tight with cable sheath clips，Black box includes that spinning is in the clamp nut 15 of metal shell tail end and the sealing ring 14 that is arranged in installing hole、Pad 13，Sealing ring 14、Pad 13 is set on cable when using，In installing hole, the front side in black box is provided with block direction shielding ring installation step 10 backwards，Shielding ring installation step 10 is wholely set with metal shell body，The shielding ring 16 for being connected it is folded with corresponding screen layer between shielding ring installation step 10 and black box，Shielding ring 16 includes cylindrical body 11 that axis extends along the longitudinal direction and is arranged at cylindrical body rear end outer and turns edge 12，Turn edge outward and 12 be sandwiched and fixed between shielding ring installation step 10 and black box，Step down end face groove 9 around being circumferentially provided with multiple solder joint in the front end of cylindrical body.
When making line at the scene, the first step, black box, shielding ring and metal shell are sequentially set on the cable 1 that screen layer 3 separates with wire 4, screen layer separate with wire after as shown in Figure 3: screen layer turns down and backward by binding strap 2(or cranse) screen layer is fixed, wire is passed by the front end of the installing hole of metal shell, is weldingly connected as shown in Figure 4 with the contact on insulator by wire；Second step, by insulator being encased in installing hole from front to back, until insulator insulated body installation step block and can not continue to move backwards, then cable is pulled back, screen layer is made to be passed by the rear end of installing hole, screen layer is welded on shielding ring the end face groove as it is shown in figure 5, solder joint is stepped down is possible to prevent solder joint too high and inner peripheral surface with shielding ring installation step is interfered outside metal shell, reduces the operation requirement to welding personnel；3rd step, dismantle binding strap, realized drawing forward cable by installing hole takes out by rear to front by insulator, under cable drives, shielding ring is encased in installing hole until by shielding ring installation step block by rear to front, by black box and shielding ring installation step, shielding ring is gripped, by insulator being encased in installing hole from front to back, until insulator insulated body installation step block and can not continue to move backwards, then by the insulator installation step in removable stop part and installing hole, insulator is gripped.Thus completing to do line, the connection of wire and contact and wire all complete with the connection of screen layer outside metal shell, are not limited by the visual field and working place, utilize and make line；By drawing cable to be pulled in installing hole by shielding ring, screen layer is in deployed condition by pulling force, can be prevented effectively from screen layer bending and affect shielding ring assembling；First insulator is loaded in installing hole, then post-tensioning cable, it is to avoid wire separates with the link position stress of contact, it is ensured that quality of connection；Utilizing shield assembly and shielding ring installation step to coordinate and grip shielding ring, the fixed structure of shielding ring is simple and convenient.
In the other embodiments of this electric connector: solder joint allows the number for end face groove can also is that one, two or other number；Certainly solder joint end face groove of stepping down can also be without setting；Screen layer can also be fastened or be fixed on shielding ring by screw；Wire can also be fixed on contact by crimping or screw connecting mode；Shielding ring installation step, insulator installation step can also be arranged with metal shell split, such as shielding ring installation step, insulator installation step are replaced by the jump ring being installed on installing hole hole wall；The pressing plate that in black box, clamp nut can also be fixed on metal shell by screw by one replaces；Removable stop part can also is that a pressing plate being fixed on metal shell by screw.
