[0031] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0032] like Figure 1 As shown, a small-sized one-piece multi-interface connector includes a main plastic housing 1 and a multi-PIN bending terminal set 4. The multi-PIN bending terminal set 4 is inserted into the main plastic housing 1, and a positioning plate 2 is connected to the main plastic housing 1 through a positioning guide seat 3. The positioning guide seat 3 is symmetrically arranged at the butt end of the main plastic housing 1, and the positioning guide seats 3 on both sides and the positioning plate 2 form a U-shaped open cavity to accommodate the multi-PIN bending terminal set 4, and the welding fixed end of the multi-PIN bending terminal set 4 is vertically penetrated and installed on the positioning plate 2.

[0033] As attached Figure 6 As shown in the figure, the main plastic shell 1 includes a plurality of window portions 11 for inserting a multi-PIN terminal group, and adjacent window portions 11 are separated by a partition 12. In each window portion 11, the window portion 11 is divided into a welding foot end 14 and a docking end 15 on both sides by a window end plate 13. The electrical connection end of the multi-PIN bent terminal group vertically penetrates the window end plate 13 and is placed in the docking end 15.

[0034] The multi-PIN bending terminal group 4 includes multiple groups, which are respectively inserted into the corresponding window parts 11, and each group of multi-PIN bending terminal groups 4 is arranged in a single row or multiple rows. Figure 3 Combined with Figure 5 As shown, when multiple groups of terminals are installed, the positioning of the bent pins is very important. In order to ensure the accuracy of the connector soldering feet, a positioning plate 2 is set at the terminal soldering foot end, and a through hole 25 corresponding to the multi-PIN bent terminal group 4 is set on the positioning plate body 23. The through hole 25 is contoured with the terminal to ensure the accuracy of the terminal position.

[0035] See attached Figure 7 The schematic diagram of the overall structure of the connector is given. While meeting the automotive standards, the main plastic shell 1 is designed to be thin and light, and the multi-connected structure shares the interface side wall, which helps to save space and is suitable for use in modules and devices installed in small spaces.

[0036] Specifically, refer to the attached Figure 6 The positioning guide seat 3 includes a support body 33, on which two parallel grooves are arranged, including a first connecting groove 31 and a second connecting groove 32. Figure 2 Combined with Figure 4 The positioning plate 2 includes a positioning plate body 23 , and a group of guide sliding buckle plates corresponding to the grooves are arranged on both sides of the positioning plate body 23 , including a first sliding buckle plate 21 and a second sliding buckle plate 22 .

[0037] A buckle protrusion 24 is disposed on the top of the first sliding buckle plate 21 , and the buckle protrusion 24 is correspondingly buckled on the boss 34 on the first connecting groove 31 ; the second sliding buckle plate 22 is slidably assembled in the second connecting groove 32 .

[0038] See attached Figure 3 Combined with Figure 4 , a schematic diagram of the connection between the positioning plate 2 and the positioning guide seat 3, at the terminal welding foot end 14, double track grooves are set on both sides, and double buckle designs on the left and right sides ensure that the positioning plate 2 is firmly connected to the positioning guide seat 3 (or the main plastic shell 1) and does not fall off. In addition, the second sliding buckle plate 22 is matched with the second connecting groove 32, both of which are groove-type structures with high strength characteristics, ensuring that the guide positioning seat as a whole does not deform, thereby ensuring the accuracy of the terminal welding position.

[0039] The snap-on protrusions 24 on both sides are tough and can bend and deform during assembly before returning to their original positions. The positioning guide seats 3 on both sides are rigid and not easily deformed. The rigidity and flexibility complement each other, and the connection is detachable and stable, ensuring the accuracy of the terminal welding position.

[0040] See attached Figure 5A positioning guide column 35 is provided at the bottom of the positioning guide seat 3 to position and fix the positioning guide seat 3 and limit the welding end of the connector; ear grooves 10 are provided on the sides of both ends of the main plastic shell 1, and the plug-in plate 5 is inserted into the ear groove 10. The bottom of the plug-in plate 5 and the positioning guide column 35 is lower than the bottom plane of the main plastic shell 1, so as to position and fix the main plastic shell 1.
