The utility model content
Technical problem to be solved in the utility model provides a kind of tail cable fastening structure of circular coaxial connector, adopt multiple fastening means, make being fastenedly connected of cable and connector can access multiple guarantee, improve connection reliability, satisfy specific use occasion, and adopt the part number few, processing is with easy to assembly.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of tail cable fastening structure of circular coaxial connector; It is characterized in that:
The tail end structure of described connector is a columniform thin-walled pressure welding case 2;
The weldering gland 1 of a sheathed stube cable in the pressure welding case 2 of described connector tail end; Described weldering gland 1 inside is a cylindrical hole; Described weldering gland 1 outside is formed by stacking by a taper seat step 11, the face of cylinder and the afterbody conical surface 13 with some hangnail structures 16 from the front portion to the rear portion successively; Described weldering gland 1 middle part offers the welding hole 12 that two above through holes weld as the wire sheathing 3 with cable;
Pressure welding case 2 interior forward end of described connector tail end are provided with crimping end face 21, and described crimping end face 21 matches with weldering gland 1 front end face 14 and is used to compress the wire sheathing 3 of cable; The thin wall cylindrical face 22 of pressure welding case 2 afterbodys of described connector tail end can be out of shape extruded sleeve by crimping and be located at wherein weldering gland 1, make crimping end face 21 and the wire sheathing 3 that welds gland 1 front end face 14 clamping cables, and the cable jacket 4 that is enclosed within outside the weldering gland 1 is pressed between thin wall cylindrical face 22 and the weldering gland 1; Described hangnail structure 6 can puncture cover cable jacket 4 externally and play further fastening effect.
Has a backflow molten tin bath 15 on the face of cylinder of described weldering gland 1 inner via hole.
The utility model can bring following beneficial effect:
1, the weldering pressure type cable fastening structure that adopts of the utility model, the connector number of spare parts reduces to some extent, and the connector overall dimensions reduced, and has saved the space.
2, adopt the cable fixed form of carrying out crimping again after the welding earlier in the utility model, crimping mode common in the prior art only compresses cable braid, the fastening means that the utility model provides not only compresses braid, simultaneously cable cover(ing) is carried out fastening, thereby improve the cable assembly connection reliability.By the thin-walled pressure welding case of compression connector shell tail end, the locking cable oversheath, and by place, inclined-plane deformation butt welding gland generation axial thrust, compress the cable metal braid, thereby play fastening cable effect; And the hangnail structure by the weldering gland punctures cable jacket, thereby cable can further be fastened on the connector, the reliability of connector assembly in the assurance work.So the utility model has improved connector tail cable reliability of fixation and assembly overall work reliability, and obvious advantage is compared with prior art arranged.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 illustrate embodiment of the present utility model, and connector and cable weldering compress solid course of work principle referring to Fig. 3, Fig. 4.
Weldering compresses the key structure design of solid mode on the weldering gland.As shown in Figure 1, the outside primary structure of weldering gland be taper seat step 11, two welding holes 12, the afterbody conical surface 13, the face of cylinder with hangnail structure 16; Weldering gland inside is a cylindrical hole, and the face of cylinder of through hole is provided with a solder reflow molten tin bath 15.
As shown in Figure 2, connector tail end structure is a columniform thin-walled pressure welding case, and primary structure is crimping end face 21 and thin wall cylindrical face 22.
The weldering gland is set in the pressure welding case of connector tail end, and the interior crimping end face 21 of the pressure welding case of its front end face 14 and connector tail end matches and is used for the wire sheathing of clamping cables.
Figure 3 shows that the schematic diagram of crimped status not after the assembling of connector and cable.1 is the weldering gland in shown in Figure 3, and 2 is the pressure welding case of connector tail end, and 3 is the cable metal braid, and 4 is cable jacket, and 5 is cable.To weld gland 1 during assembling earlier is enclosed within outside the cable metal braid 3, the head flange of cable metal braid 3 is to the front end face 14 of weldering gland 1, again cable metal braid 3 and weldering gland 1 are welded by welding hole 12, pressure welding case 2 with the connector tail end is enclosed within outside the weldering gland 1 then, cable metal braid 3 is pressed between the front end face 14 and the crimping end face 21 in the pressure welding case 2 of weldering gland 1, cable jacket 4 can easily be enclosed within on the face of cylinder with hangnail structure 16 through the weldering gland 1 afterbody conical surface 13, at this moment hangnail structure 16 does not puncture cable jacket 4, and this moment, assembly was in the loose fit state.
Figure 4 shows that the schematic diagram of connector and cable assembling back impaction state.After being assembled to state shown in Figure 3, utilize crimping apparatus that the pressure welding case 2 of connector tail end is crimped on weldering gland 1, cable 5, the extruding that taper seat step 11 conical surfaces that weld gland this moment are subjected to the thin wall cylindrical face 22 of pressure welding case 2 produces axial displacement to crimping end face 21 directions, until tightly clamping cable metal braid 3; thin wall cylindrical face 22 is pressed on weldering gland 2 to have on the face of cylinder of hangnail structure 6; cable jacket 4 is pressed between thin wall cylindrical face 22 and the weldering gland 1; cable jacket 4 parts are punctured, and play further fastening cable effect.So far, cable and connector are subjected to 3 welding of cable metal braid fastening and 3 crimping of cable metal braid and the fastening multiple action of cable jacket 4 crimping, firmly tighten together.Outline drawing after connector and cable weldering are pressed as shown in Figure 5.
