Description

Technical Field

[0001] This utility model relates to the field of terminal connectors, and in particular to a visual terminal connector structure. Background Technology

[0002] In inverters, the boost and inverter inductors are typically hidden at the bottom of the PCB. However, to allow current to flow through the PCB, the inductor wires must extend to connect to the PCB. To ensure a better and more reliable connection for the cables at the bottom of the PCB, long cables are commonly used to run around the bottom and reach the front of the PCBA before screwing them in. However, since the connection method of screwing the terminals through the PCB is a blind locking method, there is no relative parallel reference during manual locking, and it is impossible to observe whether the terminals are misaligned or offset from the PCB holes. As a result, screws may be driven crookedly or not tightened properly, leading to machine failure, overheating, and other safety issues. Machine vision or robotic arm locking is similar to manual operation, lacking a relative visual reference. Therefore, screws may also be driven crookedly or not tightened properly, resulting in a high defect rate on the production line. Furthermore, when customers use the machine at high power, it is prone to accidents. Due to the loose terminal locking, the current carrying capacity of the PCB and terminals is reduced, leading to overheating during machine use, limited performance, and a high risk of overload failure, thus reducing the customer's user experience.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a visualized terminal connector structure includes a connector mounting base 1, a connector body terminal 2, and a connector stud 3.

[0024] The connector mounting base 1 has several limiting body grooves 7. The connector body terminal 2 is installed into the limiting body groove 7. The connector mounting base 1 is a plastic base. One end of the connector body terminal 2 is connected to a connecting wire 10. The connector body terminal 2 is fixedly installed with a connector stud 3. The connector stud 3 is connected to a press-fit mounting nut 5 by a thread. The press-fit mounting nut 5 is located above the printed circuit board 4 and has no obstruction of view, so it is installed on the connector stud 3 in a visible manner.

[0025] like Figures 1-4 As shown, this utility model also discloses the following more optimized specific structures:

[0026] A printed circuit board 4 is sandwiched between the connector body terminal 2 and the press-fit mounting nut 5. The printed circuit board 4 has a plate hole corresponding to the connector stud 3. The connector stud 3 is inserted into the plate hole. The upper and lower edges of the plate hole are plated with copper foil, gold foil, tin foil or other metal foil, so that current flows from the connector body terminal 2 and the press-fit mounting nut 5 to the PCB.

[0027] The bottom of the connector mounting base 1 is connected to the base plate 6 by bolts 13. Both the connector mounting base 1 and the base plate 6 have corresponding fixing holes 14 (the fixing holes 14 on the base plate 6 are not shown in the attached diagram), facilitating their joint fixing to the inverter platform 11 (the inverter platform 11 has corresponding holes) using screws. See details... Figure 4 The quantity is set according to demand.

[0028] In another embodiment, fixing holes 14 may be provided only on the base plate 6 for fixing the base plate 6 to the inverter platform 11 by screws. Since the bottom of the connector mounting base 1 is fixed to the base plate 6 by bolts 13, the connector mounting base 1 is fixed relative to the inverter platform 11. In the case where fixing holes 14 are provided only on the base plate 6: for example, the area of ​​the base plate 6 is larger than the area of ​​the connector mounting base 1, the fixing holes 14 are provided in positions that do not correspond to the connector mounting base 1, and the screws can be tightened from top to bottom.

[0029] The connector body terminal 2 is provided with a crimping hole 8, and the bottom end of the connector stud 3 is crimped and fixed in the crimping hole 8. The connector stud 3 can be replaced by a crimping screw.

[0030] The bottom surface of the connector stud 3 is flush with the bottom surface of the connector body terminal 2.

[0031] A label sleeve 9 is installed at the connection point between the connector body terminal 2 and the connection cable 10.

[0032] Limiting main body groove 7 is provided with limiting clips 12 on both sides, and the two sides of connector main body terminal 2 are locked between the two limiting clips 2.

[0033] like Figures 1-4 The manufacturing and usage process of the visualized terminal connector structure is as follows:

[0034] Purchase pre-made connector body terminals 2. These terminals can be manufactured using an automated terminal forming workstation. A hydraulic press equipped with forming molds cuts, punches, bends, and shapes the original terminal material. Afterward, the terminals are washed and dried to remove impurities, preventing them from affecting the riveting process and strength during screw installation. Then, the connector body terminals 2 enter an automated terminal riveting workstation. A robotic arm equipped with a CCD performs the screw riveting process on the pre-formed connector body terminals 2. The CCD detects when the formed terminals reach the predetermined position and, under its calibration, aligns the screws with the terminals. The robotic arm fixes the terminal in place at the crimping hole 8, and the crimping machine crimps the screw onto the terminal to form the connector stud 3. After crimping is completed, the crimping position on the terminal surface is polished. After polishing, the terminal is transferred to the next workstation for crimping. The CCD of the crimping workstation can further ensure the accuracy and perpendicularity of the riveting, resulting in higher assembly accuracy and yield, avoiding inefficient manual production. After riveting, a polishing process is performed to reduce burrs and uneven areas on the terminal surface, increasing the smoothness of the product and the customer's user and maintenance experience. The above process is the terminal manufacturer's processing process. After processing is completed, the finished connector body terminal 2 can be purchased directly.

[0035] After the purchased terminal connector body terminal 2 arrives at the predetermined crimping station, the crimping mechanism will first strip, remove the insulation from, and twist one end of the connecting wire 10 before inserting it into the tail of the connector body terminal 2. Then, the crimping teeth of the crimping mechanism will crimp the tail of the terminal, so that the cable is crimped to the tail of the terminal. Next, the label sleeve 9 will be heated to attach the label sleeve to the cable. Then, the robotic arm will place the connector body terminal 2 into the limiting body groove 7 on the connector mounting base 1, so that the connector body terminal 2 has a certain amount of displacement, but will not dislodge due to excessive displacement, thereby avoiding safety problems such as machine explosion caused by terminals coming into contact with each other due to dislodgement.

[0036] After the robotic arm places the terminal on the connector mounting base 1, it installs the plastic base with the terminal already attached onto the base plate 6 and fixes it to the inverter platform. The printed circuit board 4 is then secured to the connector body terminal 2 by pressing the mounting nut 5, so that the lines on the printed circuit board 4 pass through the terminal and along the cable to the corresponding device.

[0037] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
