[0016] Refer to in combination Figures 1 to 3As shown in the figure, according to an embodiment of the present utility model, a crimping device for an SMP type ultra-small blind mating connector is provided, which includes a positioning seat. The positioning seat includes a top plate 1. On one side of the top plate 1, two guide rods 2 are arranged at intervals. One end of the guide rod 2 close to the top plate 1 is a first guiding portion. One end of the first guiding portion away from the top plate 1 has a limit boss 7, so as to be able to limit the pressing block 3 within the first guiding portion. The pressing block 3 can slide axially along the first guiding portion and is used to press the SMP plug 5 into the SMP socket 6. The free end of the guide rod 2 is a second guiding portion, which is adapted to the positioning hole of the SMP socket 6 and is also adapted to the guiding hole of the SMP plug 5. The SMP plug 5 can slide along the guide rod 2. The SMP connector is widely used because of its small structural size and blind plug connection, which is suitable for high-density, small-space, and high-integration application scenarios. Since the related parts of the SMP connector are very small, the assembly difficulty is large, the assembly efficiency is low, and the qualified rate is low. Especially for the connector with a crimping structure, at present, most of the operations in the production workshop are manual. The operator inserts the SMP plug 5 into the SMP socket 6. Because the SMP plug 5 of this product has an ultra-small structure, it has relatively high requirements for the operator's operation ability and proficiency. In this application, by setting a positioning seat and using the guide rod 2 for positioning and support, the guide rod 2 is inserted into the guiding hole of the SMP plug 5 and the positioning hole of the SMP socket 6 to co-axially position the SMP plug 5 and the SMP socket 6, and then the pressing block 3 is pressed in. It is ensured that the two have good coaxiality and the mouth dimensions are flush after assembly, improving the assembly efficiency and the qualified rate.

[0017] Specifically, the radial cross-section of the first guiding portion is an "I"-shaped structure, which can limit the pressing block 3 to move up and down within a certain area. During use, the guide rod 2 is inserted into the mounting holes at both ends of the pressing block 3, and pressed forcefully to press the pressing block 3 into the first guiding portion to realize the limiting function of the pressing block 3.

[0018] In a specific embodiment, a through hole is provided at the axial center of the top plate 1. The positioning post 4 passes through the through hole and abuts against the pressing block 3. The end of the positioning post 4 close to the pressing block 3 has an annular flanging. Since the SMP plug 5 is relatively small, the volume of the crimping device provided in this application is also relatively small. Although the pressing block can be pulled downward at the connection between the pressing block 3 and the guide rod 2 to insert the SMP plug 5 into the SMP socket 6. However, due to the small volume, it is not convenient for the staff to grip, which affects the assembly efficiency. Therefore, a through hole is opened at the axial center of the top plate 1, the positioning post 4 is inserted into the through hole, and pressure is applied to the positioning post 4, so as to achieve the purpose of applying pressure to the pressing block 3, and the SMP plug 5 is inserted into the SMP socket 6, which is convenient and fast, and improves the assembly efficiency. And an annular flanging structure is provided at the end of the positioning post 4 close to the pressing block 3, which can limit the positioning post 4 in the through hole, make the whole structure an integral body, facilitate the use and carrying of the whole device, and avoid temporary assembly and waste of working hours. And the annular flanging structure can increase the contact area between the positioning post 4 and the pressing block 3, and improve the crimping effect.

[0019] In a specific embodiment, on opposite sides of the circumferential side wall of the pressing block 3, extending radially outward along the radial direction to form protruding ends. In addition to adopting the technical solution of pressing the pressing block 3 with the positioning post 4 as described above, two protruding ends can also be directly integrally formed on the circumferential side wall of the pressing block 3. During use, the staff presses the protruding ends (like an ear structure) to realize the downward movement of the pressing block. The structure is simple, the manufacturing cost is low, no additional parts are required, and the production is convenient.

[0020] In a specific embodiment, a rubber sleeve is sleeved on the second guiding portion. A rubber sleeve is provided at the position of the second guiding portion to increase the friction between the guide rod 2 and the SMP plug 5 and between the guide rod 2 and the SMP socket 6, which can improve the positioning stability.

[0021] In a specific embodiment, the first guiding portion and the second guiding portion are detachably connected. During the actual production process, the hole pitch of the guiding hole of the SMP plug 5 and the positioning hole of the SMP socket 6 are different. By detachably connecting the first guiding portion and the second guiding portion, the distance between the two guide rods can be set more freely to adapt to the installation of more specifications of products. For example, the second guiding portion is designed into a "ㄑ" - shaped structure, and the first guiding portion and the second guiding portion are threadedly connected.

[0022] In a specific embodiment, the guide rod 2 is of a cylindrical structure, and the diameter of the second guiding portion decreases. The diameter of the guide rod 2 is set to a decreasing structure, which can be more conveniently inserted into the guiding hole and the positioning hole, facilitating the operation.

[0023] The working process of this application is as follows:

[0024] Insert the positioning post 4 into the through hole of the top plate 1, and then insert the two guide rods 2 into the mounting holes at both ends of the pressing block 3 respectively. Press the pressing block 3 forcefully to press the pressing block 3 into the first guiding portion so that the pressing block 3 can slide within the first guiding portion. The crimping device is assembled. Select a suitable distance between the guide rods 2 according to the size of the SMP product to be installed. When in use, pass the guide rods 2 through the guiding holes of the SMP plug 5, and then insert the guide rods 2 into the positioning holes of the SMP socket 6. After positioning, press the positioning post 4. The positioning post 4 moves downward, and the positioning post 4 pushes the pressing block 3 and the SMP plug 5 to move downward together until the SMP plug 5 is completely inserted into the SMP socket 6. The installation is completed. Pull out the pressing device, and the product installation is completed.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention.
