[0034] like Figures 1 to 7 The terminal mold quick-change device shown includes a movable bracket 1, a crimping mold assembly 2, and a quick-change assembly 3, as detailed below. Figure 1 As shown, both the crimping mold assembly 2 and the quick-change assembly 3 are mounted on the movable bracket 1. The movable bracket 1 has various specific structural forms, which can be configured according to the needs of those skilled in the art. In the embodiment of this utility model, the crimping mold assembly 2 is fixed on the movable bracket 1. The crimping mold assembly 2 includes a crimping component 21, the position of which on the movable bracket 1 is adapted to the position of the mold to be replaced. The quick-change assembly 3 is disposed on the movable bracket 1 and faces the host machine to be replaced. The quick-change assembly 3 includes a connector 31 fixed on the movable bracket 1. The host machine to be replaced also has a plug-in socket 32 ​​adapted to the connector 31. The plug-in socket 32 ​​also includes a locking member 33 for locking the connector 31.

[0035] When replacing the old locking piece 33, first open the old locking piece 33, then pull out the connector 31, and then insert the connector 31 on the new terminal mold quick change device into the plug socket 32 ​​on the main unit. At this time, the new crimping assembly 21 is just locked into the connection of the crimping drive mechanism. Then, the connector 31 is locked onto the plug socket 32 ​​by the locking piece 33, so as to realize the quick replacement of the crimping mold.

[0036] In the above embodiment, by setting a quick-change component 3 on the movable bracket 1, the crimping mold component 2 on the movable bracket 1 can be quickly assembled with the plug-in socket 32 ​​on the host through the connector 31 on the movable bracket 1 during the process of moving the bracket 1. Compared with the manual mold replacement method in the prior art, the replacement efficiency and accuracy are greatly improved.

[0037] like Figure 2 and Figure 3 As shown in the embodiment of this utility model, the plug-in base 32 has a transversely penetrating plug groove 321, and the connector 31 has a plug portion 311. The thickness of the plug portion 311 is adapted to the depth of the plug groove 321, and the width of the plug portion 311 is smaller than the width of the plug groove 321. In the embodiment of this utility model, transverse penetration means as... Figure 2 and Figure 3The plug slot 321 shown is open at both ends. In addition, in the embodiment of this utility model, the plug socket 32 ​​has a connection hole at the end away from the plugging direction for connecting with the host. It should be noted that in the embodiment of this utility model, the plug socket 32 ​​on the terminal mold quick change device can be pre-fixed on the connector, or the old plug socket 32 ​​installed on the host can be used.

[0038] In the embodiments of this utility model, the specific structural form of the plug-in socket 32 ​​is as follows: Figure 2 and Figure 3 As shown, a plurality of rollers 322 are rotatably connected to the connector 32. These rollers 322 are disposed on the sidewall of the connector groove 321, and the sidewalls of the rollers 322 roll into contact with the sidewall of the connector 311 when the connector 311 is inserted into the connector groove 321. Thus, during the insertion of the connector, please refer to... Figure 2 and Figure 3 Both sides of the insertion portion 311 are in rolling contact with the roller 322, which guides the insertion of the connector 31 and reduces the resistance during insertion. Furthermore, in this embodiment, the insertion end of the connector 31 has rounded corners, such as... Figure 2 As shown, the rounded corners can further provide a guiding function, thereby improving the accuracy of its insertion into the connector 32.

[0039] For details regarding the specific structural forms of the locking element 33 and the connector 31, please refer to [link / reference needed]. Figure 2 and Figure 3 In this embodiment of the invention, the plug-in portion 311 has a locking channel 312. The locking channel 312 is provided at the insertion end opening of the plug-in portion 311. The locking member 33 is screwed into the plug-in groove 321, and the locking member 33 is adapted to the position of the locking channel 312. The locking member 33 presses against the plug-in portion at the top to achieve locking. The locking channel 312 allows the locking member 33 to enter into it, and then the locking member 33 presses against the plug-in portion to fix the connector 31. The specific structure of the locking member 33 is as follows... Figure 4 As shown, the locking member 33 includes a stud 331 screwed to the bottom of the insertion slot 321, a nut 332 fixed to the top of the stud 331, and an operating handle 333 fixed to the nut 332. During insertion, the operating handle 333 is first turned in the reverse direction so that the height of the nut 332 is higher than the upper surface of the connector 31. After the connector 31 is inserted, the locking member 33 enters the locking channel 312. Then, the operating handle 333 is turned in the forward direction so that the height of the nut 332 decreases to press against the connector 31, thereby reliably fixing the connector 31 to the insertion socket 32.

[0040] In the embodiments of this utility model, to ensure that the insertion position is consistent each time it is plugged in, please continue to refer to... Figure 2 and Figure 3 The connector 32 has a horizontally screwed limiting screw 323 at one end facing the connector 31. The limiting screw 323 is used to adjust the insertion depth of the connector 32, and the top of the limiting screw 323 abuts against the movable bracket 1. In this embodiment of the present invention, the limiting screw 323 is screwed onto the end of the connector 32 facing the movable bracket 1. By adjusting the length of the limiting screw 323, during the insertion of the connector 31 into the connector 32, the limiting screw 323 on the connector 32 contacts the side wall of the movable bracket 1. When in contact, the insertion depth of the connector 31 is blocked, thereby ensuring that the position of the connector 31 pushed into the connector 32 is consistent each time.

[0041] In the embodiments of this utility model, the specific structure of the movable support 1 is as follows: Figure 5 As shown, the movable bracket 1 includes a base and a support frame. The base is U-shaped and has multiple casters at its bottom. The U-shape, with the opening facing the main unit, allows the base to move a greater distance towards the main unit to accommodate various insertion depths. In this embodiment, the main unit refers to a device for crimping wire harness terminals, and this device has dimensions corresponding to the movable bracket 1. Please continue to refer to... Figure 5 In this embodiment of the utility model, the support frame is fixedly connected to the top of the base; the pressing assembly 21 is fixed to the top of the support frame.

[0042] Specifically, in the embodiments of this utility model, such as Figure 5 As shown, the crimping die assembly 2 also includes a feeding assembly, which includes a feeding disc rotatably connected to the middle of the support frame, a guide wheel and a guide groove disposed between the feeding disc and the crimping assembly 21. Through the feeding disc, the strip with terminals sequentially passes through the guide wheel and guide groove into the crimping assembly 21. Therefore, with the above configuration, there is no need to separately replace the strip; instead, a different type of terminal can be crimped directly by replacement. Compared with existing technologies, this greatly improves the efficiency of changing materials, dies, and terminals.

[0043] Please refer to Figure 6 and Figure 7 In embodiments of this utility model, in addition to the crimping assembly 21 and the feeding assembly, the quick-change assembly 3 also includes an electrical quick-connect connector 34, which is a magnetic connector. Figure 7As shown, the magnetic connector enables rapid connection of electrical connectors on the terminal mold quick-change device. Connection is achieved magnetically as long as they come into contact. Specifically, the magnetic connector is existing technology, using magnetic attraction to bring the male and female connectors into contact and connect. In specific configuration, either the male or female connector can be fixed to the main unit, while the other connector is connected to the movable bracket 1. Their relative positions are configured such that when the connector 31 and the socket 32 ​​are pushed into the correct position, the male and female connectors of the electrical quick-connect connector 34 are also precisely in the mating position, achieving connection through magnetic attraction.
