[0002] A riveting machine uses a stamping machine and a special connecting mold to connect two or more layers of plates of different materials and thicknesses through a high-pressure instantaneous processing process based on the cold extrusion deformation of the plate material itself.

[0003] A shielded connector is an electronic component that uses special design and materials to protect against electromagnetic interference. Its core function is to block electromagnetic interference radiation from entering or leaking. Existing shielded connectors are fixed to the cable through a riveting process to prevent the connector from falling off.

[0004] However, after riveting the shielded connector, the petals of the shielded connector are prone to deformation and deviate towards the center pin, which reduces the riveting quality of the shielded connector. Therefore, it is necessary to propose a connector riveting assembly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a connector riveting assembly to solve the problem mentioned above where, after riveting a shielded connector, the petals of the shielded connector are easily deformed, causing the petals to deviate towards the central PIN pin, thus reducing the riveting quality of the shielded connector.

[0009] Preferably, the lifting mechanism includes columns, which are fixedly installed on the top of the base plate. There are two columns, which are symmetrically distributed about the center line of the placement seat. A top plate is fixedly connected between the upper ends of the two columns. A pneumatic cylinder is fixedly installed in the middle of the top of the top plate. A lifting seat is movably fitted between the two columns. The telescopic end of the pneumatic cylinder is fixedly connected to the lifting seat. The upper die is located at the bottom of the lifting seat.

[0018] 4. By installing the mounting mechanism, when the spring force of the spring baffle decreases, the push rod is pushed to move inside the limiting groove, which in turn moves the fixed rod towards the direction of the helical spring, thereby removing the restriction on the rectangular rod. The rectangular rod can then be pulled out of the slot and replaced with a new spring baffle installed in reverse, thus improving the practicality of this connector riveting assembly.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-5The connector crimping assembly shown includes a base plate 1. A placement seat 2 is fixedly mounted on the top of the base plate 1. The placement seat 2 has a placement groove 11 and a venting groove 12 fixedly formed inside. Both the placement groove 11 and the venting groove 12 have semi-circular vertical cross-sections and are concentrically arranged. The placement groove 11 extends through the front end of the placement seat 2. The inner diameter of the venting groove 12 is larger than the inner diameter of the placement groove 11. A shielded connector 13 is placed inside the placement groove 11. The petal end of the shielded connector 13 is located inside the venting groove 12, and there is a gap between the petal end of the shielded connector 13 and the rear sidewall of the venting groove 12. The top of the base plate 1 is provided with a riveting part, which includes a lower die 10 and an upper die 7. The front end of the placement seat 2 is fixedly provided with a support platform 9. The lower die 10 is fixedly provided in the middle of the top of the support platform 9. The upper die 7 is movably provided directly above the lower die 10 through a lifting mechanism. The lower die 10 has a first riveting groove fixedly provided inside, and the upper die 7 has a second riveting groove fixedly provided inside. The shielded connector 13 is inserted between the first riveting groove and the second riveting groove. The vertical cross section of the first riveting groove is semi-circular, and the inner diameter of the first riveting groove is the same as the inner diameter of the placement groove 11. The placement groove 11 and the first riveting groove are arranged concentrically.

[0027] Specifically, during use, the shielded connector 13 is placed on the first riveting groove and the placement groove 11. With the setting of the venting groove 12, when the upper die 7 moves downward to rivet the shielded connector 13, the petal end of the shielded connector 13 has room to move, avoiding the front end of the petal end being blocked. During riveting, due to inertia, the shielded connector 13 has a large impact force that causes the petal end to deform. This solves the problem that after the existing connector riveting assembly rivets the shielded connector 13, the petals of the shielded connector 13 are easily deformed and the petals are biased towards the center PIN pin, which reduces the riveting quality of the shielded connector 13.

[0028] Furthermore, the lifting mechanism includes a column 3, which is fixedly installed on the top of the base plate 1. There are two columns 3, which are symmetrically distributed about the center line of the placement seat 2. A top plate 4 is fixedly connected between the upper ends of the two columns 3. A pneumatic cylinder 5 is fixedly installed in the middle of the top of the top plate 4. A lifting seat 6 is movably fitted between the two columns 3. The telescopic end of the pneumatic cylinder 5 is fixedly connected to the lifting seat 6. The upper die 7 is set at the bottom of the lifting seat 6.

[0029] Specifically, after placing the shielded connector 13 on the first riveting groove and the placement groove 11, the pneumatic cylinder 5 is activated to drive the lifting seat 6 and the upper die 7 to move downward, so that the lower die 10 and the upper die 7 can rivet the shielded connector 13, so that the shielded connector 13 is fixedly connected to the cable and prevents the shielded connector 13 from falling off.

[0030] To facilitate quick assembly and disassembly of the upper die 7, an installation groove is provided inside the lifting seat 6. An installation plate is fixedly installed on the top of the upper die 7. The installation plate is inserted into the installation groove, and a bolt 8 is threadedly connected between the installation plate and the lifting seat 6. The installation groove, installation plate, and bolt 8 facilitate the assembly and disassembly of the upper die 7, thereby improving the maintenance efficiency of the connector riveting assembly.

[0031] Furthermore, a spring baffle 14 is provided at the bottom of the lifting seat 6 via an installation mechanism. The spring baffle 14 is located in front of the upper die 7, and there is a gap between the spring baffle 14 and the upper die 7. By setting the spring baffle 14, when riveting the shielded connector 13, the shielded connector 13 is prevented from being stuck in the upper die 7, thereby preventing the shielded connector 13 from deforming, and facilitating the unloading operation of the shielded connector 13.

[0032] Furthermore, the installation mechanism includes a rectangular rod 15, which is fixedly mounted at the end of the spring baffle 14. The lifting seat 6 has a slot for engaging the rectangular rod 15 inside. The lifting seat 6 has a sliding groove 16 inside. The rectangular rod 15 has a corresponding slot 17 inside. A fixing rod 19 is slidably arranged between the sliding groove 16 and the slot 17. A helical spring 18 is fixedly connected between the fixing rod 19 and the side wall of the sliding groove 16. A push rod 20 is fixedly mounted at the bottom of the fixing rod 19. A limiting groove for the push rod 20 to move is provided below the sliding groove 16.

[0033] When the spring force of the spring baffle 14 decreases, it needs to be replaced. At this time, push the push rod 20 to move it inside the limiting groove, which will drive the fixed rod 19 to move towards the helical spring 18, thereby removing the restriction on the rectangular rod 15. Pull the rectangular rod 15 out of the slot and replace it with a new spring baffle 14 and install it in reverse, thus improving the practicality of this connector riveting assembly.

[0034] Working principle: During use, the shielded connector 13 is placed on the first riveting groove and the placement groove 11, with the petal end of the shielded connector 13 located inside the venting groove 12. The pneumatic cylinder 5 is activated, driving the lifting seat 6 and the upper die 7 to move downwards, allowing the lower die 10 and the upper die 7 to rivet the shielded connector 13, thus fixing the shielded connector 13 to the cable and preventing it from falling off. At the same time, the venting groove 12 provides space for the petal end of the shielded connector 13 to move when the upper die 7 moves downwards to rivet the shielded connector 13, preventing the front end of the petal end from being blocked. During riveting, due to inertia, the shielded connector 13 experiences a large impact force backwards, causing the petal end to deform. After riveting is completed, the pneumatic cylinder 5 is activated in the reverse direction. At this time, the spring baffle 14 prevents the shielded connector 13 from being stuck in the upper die 7, thereby preventing deformation of the shielded connector 13 and facilitating the unloading operation of the shielded connector 13.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
