[0029] refer to Figures 1 to 4 This embodiment discloses a plug crimping device.

[0030] like Figures 1 to 4 As shown, the plug crimping device includes a fixed base 100, multiple first crimping modules 200, multiple second crimping modules 300, and a pushing structure 400. The fixed base 100 is provided with a pushing platform.

[0031] 110. A plurality of first pressing modules 200 are individually replaceable on the pressing platform 110. The first pressing modules 200 are detachably connected to the pressing platform 110 and are used to define the position of the plug housing and the cable. A plurality of second pressing modules 300 are individually replaceable on the first pressing modules 200 and are used to define the position of the connector housing. A pressing structure 400 is provided on the fixing base 100 and is located on one side of the pressing platform 110. The second pressing modules 300 are located at the end of the first pressing modules 200 away from the pressing structure 400. The pressing structure 400 is configured to press the parts toward the direction of the second pressing modules 300 to achieve product assembly.

[0032] like Figure 1 As shown, the fixed base 100 is arranged in the front-to-back direction, and the pressing platform 110 is located at the rear end of the fixed base 100. The first pressing module 200 is detachably connected to the pressing platform 110, so multiple first pressing modules 200 can be interchangeably arranged on the pressing platform 110. The second pressing module 300 is detachably connected to the first pressing module 200, so multiple second pressing modules can be interchangeably arranged on the first pressing module 200. The pressing structure 400 is located on the front side of the pressing platform 110, and its output end acts rearward on the part defined on the first pressing module 200. Thus, by adopting a modular design, the traditional integrated mold is decomposed into the separately replaceable first pressing module 200 and second pressing module 300. Both are detachably installed on the pressing platform 110. The pressing structure 400, as a universal drive component, only needs to replace the corresponding module to adapt to different plug specifications. Therefore, adaptation can be completed without replacing the entire equipment, reducing mold development costs and improving production efficiency and adaptability while realizing flexible production of small batches and multiple varieties.

[0033] In some specific embodiments of this utility model, the first pressing module 200 includes a first limiting seat 210 and a second limiting seat 220. The first limiting seat 210 is sleeved on the pressing platform 110 and is detachably connected to the pressing platform 110 through a connecting structure 230. The second limiting seat 220 is located at the upper end of the first limiting seat 210 and has a first limiting groove 221 and a second limiting groove 222. The first limiting groove 221 and the second limiting groove 222 are interconnected. The second limiting groove 222 is located at the end of the first limiting groove 221 away from the pressing structure 400. The first limiting groove 221 is used to limit the position of the plug shell, and the second limiting seat 220 is used to limit the position of the cable.

[0034] like Figure 1 and Figure 3 As shown, the first pressing module 200 consists of a first limiting seat 210 and a second limiting seat 220. The first limiting seat 210 is detachably mounted on the pressing platform 110 via a connecting structure 230. The second limiting seat 220 is located on top of the first limiting seat 210. Its interior has a first limiting groove 221 for precisely positioning the plug housing and a second limiting groove 222 located at the far end for fixing the cable, forming a continuous limiting channel that keeps the housing and cable aligned during pressing. Thus, the first limiting groove 221 constrains the lateral displacement of the plug housing, and the second limiting groove 222 simultaneously fixes the cable routing, preventing defective products caused by cable misalignment during pressing, further enhancing the versatility and ease of maintenance of the device.

[0035] In some specific embodiments of this utility model, the second pressing module 300 includes a third limiting seat 310, which is disposed within the first limiting groove 221. The third limiting seat 310 has a third limiting groove 311, which is used to limit the position of the interface shell. Figure 1 and Figure 4 As shown, the third limiting seat 310 is nested within the first limiting groove 221 of the first pressing module 200, forming a stacked limiting structure. The third limiting groove 311 on the third limiting seat 310 is specifically designed for precise engagement of the interface housing. Thus, the first limiting groove 221 secures the plug housing, the second limiting groove 222 secures the cable, and the third limiting groove 311 further constrains the position of the interface housing, forming a progressively guiding pressing path. This ensures that the interface housing maintains strict alignment with the plug housing and cable during the pressing process, preventing misalignment or loosening during assembly. It should be noted that the modular structure allows for individual adjustment or replacement of the third limiting seat 310 to adapt to different interfaces, improving the device's compatibility with different interface types and production flexibility without modifying the overall mold.

[0036] Specifically, the width of the first limiting groove 221 and the second limiting groove 222 is the extension distance along the left and right direction, and the length is the extension distance along the front and back direction. The first limiting groove 221 corresponds to the physical dimensions of the plug shell, and the width and length of the second limiting groove 222 correspond to the physical dimensions of the interface shell. This transforms the geometric features of different plug and interface models, such as rectangular contours and elliptical contours, into a standardized dimension database of limiting grooves. Therefore, when changing product models, it is only necessary to call the preset combination of the first limiting groove 221 and the second limiting groove 222 to automatically adapt to the assembly requirements of the new product without redesigning the mold structure.

[0037] It should be noted that in this specific embodiment, the plug is the input port of the socket, power adapter, etc. Common plugs include two-hole and three-hole power plugs. The interface here can be a pluggable interface such as Type-A or Type-C, or it can be interpreted as a non-pluggable fixed terminal.

[0038] In some specific embodiments of this utility model, the third limiting seat 310 has a fourth limiting groove 312, which is located between the second limiting groove 222 and the third limiting groove 311. The fourth limiting groove 312 is connected to the second limiting groove 222 and the third limiting groove 311 respectively. The fourth limiting groove 312 corresponds to the second limiting groove 222. The fourth limiting groove 312 is used to limit the position of the interface shell and the cable connection.

[0039] like Figure 4As shown, a fourth limiting groove 312 is provided on the rear side of the third limiting groove 311 and communicates with it. The bottom of the fourth limiting groove 312 is an arc shape adapted to the cable. It is located between the second limiting groove 222 and the third limiting groove 311 and is configured to constrain the joint part of the interface shell and the cable together with the third limiting groove 311, forming a three-stage linkage limiting channel, which optimizes the pressing accuracy and ensures that the first pressing module 200 and the second pressing module 300 make structural avoidance when the plug and interface are pressed together. This avoids cable bending or poor contact caused by stress concentration and ensures assembly accuracy and quick changeover capability.

[0040] In some specific embodiments of this utility model, the second pressing module 300 and the first pressing module 200 are interference-fitted. For example... Figure 1 As shown, the second pressing module 300 has a capsule-shaped cross-section and is embedded in the first pressing module 200, with both its left and right ends abutting against the first pressing module 200, thus achieving an interference fit. Specifically, the rear end of the first pressing module 200 has a limiting platform for placing the second pressing module 300. When the second pressing module 300 is embedded in the limiting platform of the first pressing module 200, the fourth limiting groove 312 corresponds exactly to the second limiting groove 222. It should be noted that the width of the limiting platform in the front-to-back direction is smaller than the width of the second pressing module 300 in the front-to-back direction, in order to provide a force point and help the operator separate the second pressing module 300 from the first pressing module 200 when replacing it.

[0041] In some specific embodiments of this utility model, the connection structure 230 includes multiple connection components 231, all of which are connected to the first limiting seat 210 and the pushing platform 110. The multiple connection components 231 are distributed at opposite ends of the pushing platform 110, thereby realizing the rapid locking and releasing of the first limiting seat 210.

[0042] In some specific embodiments of this utility model, the connecting component 231 includes a first fastening part 2311 and a second fastening part 2312. The first limiting seat 210 and the limiting platform are provided with the first fastening part 2311 and the other is provided with the second fastening part 2312. The first fastening part 2311 and the second fastening part 2312 are fastened and separated to realize the detachable connection between the first limiting seat 210 and the pushing platform 110.

[0043] like Figure 2 and Figure 3As shown, there are two connecting components 231, located at the left and right ends of the fixing base 100, respectively. Specifically, the first fastening part 2311 is a protrusion structure on the fixing base 100, and the second fastening part 2312 is a groove structure on the first limiting seat 210. Both the protrusion and groove structures are aligned and fitted together in the vertical direction to form a rigid connection. The bidirectional fastening offsets the lateral stress during the pressing process, ensuring that the module does not wobble under force. Furthermore, assembly and disassembly can be completed simply by vertical lifting or pressing, significantly improving operational efficiency compared to traditional bolt fixing methods.

[0044] Of course, the first fastening part 2311 can also be a groove structure provided on the fixed seat 100, and correspondingly, the second fastening part 2312 is a protrusion structure provided on the first limiting seat 210 that matches the groove structure.

[0045] In some specific embodiments of this utility model, the pressing structure 400 includes a driving component 410, a pressing rod 420, and a limiting component 430. The driving component 410 is mounted on the fixed base 100, and the pressing rod 420 is located at the output end of the driving component 410. The pressing rod 420 extends along the pressing direction of the product. A stop block 421 is provided at one end of the pressing rod 420 near the pressing platform 110. The stop block 421 is used to stop the part. The limiting component 430 is mounted on the fixed base 100 and is connected to the pressing rod 420. The limiting component 430 is used to limit the axial movement of the pressing rod 420.

[0046] In some specific embodiments of this utility model, the drive assembly 410 includes a first hinge 411, a second hinge 412, a drive rod 413, and a connector 414. The first hinge 411 is disposed on the fixed base 100 and is hinged to one end of the second hinge 412. One end of the drive rod 413 is hinged to the other end of the second hinge 412, and the drive rod 413 is located at the end of the second hinge 412 away from the first hinge 411. The other end of the drive rod 413 can rotate around the second hinge 412. One end of the connector 414 is hinged to the second hinge 412, and the other end is hinged to the end of the push rod 420.

[0047] Specifically, the drive assembly 410 consists of a double-lever mechanism formed by a first hinge 411 fixed to the base, a second hinge 412, a drive rod 413, and a connector 414. Figure 1As shown, the second hinge 412 has an upwardly curved, zigzag-shaped structure, and the connecting member 414 has a downwardly curved, zigzag-shaped structure. A stop block 421 is fixedly installed at the rear end of the push rod 420. That is, when the drive rod 413 is subjected to external force and rotates counterclockwise, the connecting member 414, acting as a fulcrum for the second hinge 412, pushes the push rod 420 axially. Finally, the stop block 421 precisely transmits the pressure to the plug part to be pressed. Simultaneously, the limiting component 430 constrains the push rod 420's axial movement, preventing jamming or wear caused by uneven loading, and ensuring the linearity and repeatability of the pressing process.

[0048] In some specific embodiments of this utility model, the limiting component 430 includes a limiting cylinder 431 and a limiting frame 432 that fixes the limiting cylinder 431 on the fixed base 100. The limiting cylinder 431 is arranged along the axial direction of the pushing rod 420 and is sleeved in the pushing rod 420 to limit the moving direction of the pushing rod 420.

[0049] like Figure 1 and Figure 2 As shown, the limiting cylinder 431 is fixed to the limiting frame 432 along the axial direction through the limiting frame 432 to form a rigid support frame. Its inner hole forms a clearance fit with the push rod 420, which not only ensures the free sliding of the push rod 420, but also effectively suppresses radial swing or deflection. This constrains the movement of the push rod 420 on a single axis, ensuring the vertical alignment of the abutment block 421 and the contact surface of the part during the pressing process, and avoiding the problem of part damage or improper assembly caused by angular deviation.

[0050] In some specific embodiments of this utility model, it should be further explained that the plug assembly includes a plug housing, a front cover, and a rear cover. The pressing process involves assembling the front cover and the rear cover to the opposite ends of the plug housing. Therefore, the pressing principle of the plug product is as follows: according to the product requirements, the corresponding first limiting groove 221 and second limiting groove 222 are combined. The parts to be pressed are placed sequentially in the first limiting groove 221 along the circumference of the push rod 420. At the same time, the interface is placed in the third limiting groove 311, and the cable is placed in the second limiting groove 222 and the fourth limiting groove 312. The pressing drive is rotated counterclockwise. Through the fulcrum action of the second hinge 412, the connecting piece 414 is driven to push the push rod 420 axially. Finally, under the guidance of the limiting cylinder 431, the pressure is accurately transmitted to the plug parts to be pressed by the abutment block 421, completing the entire pressing process.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
