[0032] In addition, the present invention provides examples of various specific processes and materials, but a person skilled in the art may be aware of the application of other processes and / or the use of other materials.

[0033] refer to Figures 1 to 7 As shown, the utility model discloses a novel coaxial riveting device, comprising a fixed end 1 and a movable end 2; the movable end 2 performs lifting and lowering motion relative to the fixed end 1, and is used for riveting and fixing a coaxial connector 4 on a rear cover 3;

[0034] The fixed end 1 is provided with a positioning groove 11; the rear cover 3 is fitted in the positioning groove 11, and the coaxial connector 4 is pre-installed in its mounting hole 31; the bottom of the positioning groove 11 is provided with a fixed riveting shaft 5 that is colinear with the coaxial connector 4; the fixed riveting shaft 5 is provided with a through hole 51 for the coaxial connector 4 to movably penetrate, and a plurality of protrusions 52 are provided on the end surface of the fixed riveting shaft 5 facing the coaxial connector 4, and the protrusions 52 are used to rivet the steps 41 on the circumference of the coaxial connector 4 to form a toothed or annular axial limiting portion 42 between the coaxial connector 4 and the rear cover 3 (see Figure 7 );

[0035] The movable end 2 is provided with a movable riveting shaft 21 which is colinear with the coaxial connector 4 and is used for press-fitting the coaxial connector 4 into the mounting hole 31 of the rear cover 3 .

[0036] Specific embodiments of the present utility model are shown below.

[0037] A plurality of guide components are arranged between the fixed end 1 and the movable end 2; the guide components include a guide post 6 fixed to the movable end 2 and a guide sleeve 7 fixed to the fixed end 1. The movable cooperation between the guide post 6 and the guide sleeve 7 ensures that the lifting direction of the movable end 2 relative to the fixed end 1 is stable and does not deviate.

[0038] The fixed end 1 is provided with a height-adjustable buffer pad 8 for buffering the impact force when the movable end 2 descends and limiting the moving stroke of the movable end 2 to prevent the movable end 2 from crushing the rear cover 3 and the coaxial connector 4.

[0039] Furthermore, the fixed end 1 is provided with a mounting post 9, and the buffer pad 8 is threadedly connected to the mounting post 9 via a screw 10 to achieve height adjustment, and can be adaptively adjusted to suit back covers of different thicknesses.

[0040] Secondly, the position of the screw rod 10 on the mounting column 9 is limited by the nut 20 .

[0041] The lower end of the fixed riveting shaft 5 is detachably mounted on the bottom of the positioning groove 11 by means of threaded connection, screw locking, etc., so as to facilitate disassembly and replacement.

[0042] The protrusions 52 are arranged at equal angles around the center line of the fixed riveting axis 5 to ensure that the step 41 of the coaxial connector 4 can be evenly stressed.

[0043] The outer edge of the end surface of the above-mentioned protrusion 52 is provided with a chamfered corner 521. The chamfered corner 521 can make the initial contact area between the protrusion 52 and the coaxial connector 4 smaller during the riveting process, making it easier to squeeze the step 41 of the coaxial connector 4 and deform it to expand outward, finally forming a tooth-shaped or annular axial limit portion 42.

[0044] Through the above scheme, the utility model sets a fixed riveting shaft 5 in the positioning groove 11 of the fixed end 1, and the fixed riveting shaft 5 has a protrusion 52 opposite to the coaxial connector 4. When the movable end 1 moves and rivets the coaxial connector 4 into the mounting hole 31 of the rear cover 3, the fixed riveting shaft 5 contacts the step 41 of the coaxial connector 4 at the same time and deforms to form an axial limiting portion 42 that can axially limit the coaxial connector 4, thereby preventing the coaxial connector 4 from being lifted up by the wiring harness and falling off the rear cover 3 in the subsequent process, thereby improving the reliability of the product; the utility model only adds the fixed riveting shaft 5, does not change the process, does not increase the time, and makes the product more firm and stable.

[0045] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
