[0032] As attached Figure 1-4 As shown, this embodiment provides a screw-locked solder plate type bent IPT connector, including a connector assembly, a locking screw assembly 14, a mounting interface 15, a solder plate socket 16, and a PCB board 17. The locking screw assembly 14 locks the connector assembly onto the mounting interface 15, the solder plate socket 16 is disposed on the PCB board 17, and the connector assembly fixes the mounting interface 15 onto the PCB board 17.

[0033] As a preferred embodiment of the present invention, the connector assembly includes a housing assembly and a cable assembly, wherein the cable assembly is fixed in the housing assembly.

[0034] As a preferred embodiment of this utility model, the housing assembly includes a plug housing 1, a screw sleeve 8, a sealing ring 9, a shielding cover 10, a mounting plate 11, a power insert 12, and a locking screw assembly 14. The bottom of the plug housing 1 is provided with a sealing ring 9. The screw sleeve 8 is riveted into the plug housing 1. The spring clip on the mounting plate 11 is snapped open and locked in the groove inside the plug housing 1. The power insert 12 is interference-fitted in the mounting plate 11. The shielding cover 10 is enclosed and installed in the mounting plate 11 and is limited and fixed by the spring clip on the mounting plate 11.

[0035] As a preferred embodiment of this utility model, the cable assembly includes a power socket 2, a shielding outer ring 3, a shielding inner ring 4, a sealing body baffle 5, a sealing body 6, a tail clip 7, and a cable 13. The tail clip 7, the sealing body 6, the sealing body baffle 5, and the shielding inner ring 4 are sequentially fitted onto the tail end of the cable 13. The shielding outer ring 3 is fitted onto the head of the cable 13 and the shielding inner ring 4 and the shielding outer ring 3 are pressed together. The power socket 2 is fitted onto the head of the cable 13 and pressed together. The cable assembly is installed into the plug housing 1. The spring tabs on both sides of the power socket 2 open and engage with the grooves provided in the plug housing 1, thus fixing the cable assembly to the housing assembly. At the same time, the sealing body baffle 5, the sealing body 6, and the tail clip 7 at the tail end of the cable 13 are installed into the plug housing 1.

[0036] As a preferred embodiment of this utility model, the interference fit structure of the power insert 12 into the mounting plate 11 is shark tooth shaped.

[0037] The connector described in this embodiment is specifically illustrated below:

[0038] like Figure 1 As shown, the bottom of the plug housing 1 is provided with a sealing ring 9. The sealing ring 9 is designed with 2 to 4 lips (colors: red, blue, green, white, black) for waterproof sealing when the plug assembly is installed to the customer's enclosure mounting interface 15.

[0039] The sealing body baffle 5, the sealing body 6, and the tail clip 7 are sequentially installed at the tail of the plug housing 1. The sealing body baffle 5 is blocked by the support platform at the tail of the plug housing to prevent it from pushing forward. The tail clip 7 is fastened to the plug housing 1 to prevent it from coming out. The sealing body 6 is clamped and fixed in the middle for waterproof sealing at the tail of the plug assembly. After the tail cover 7 is fastened in place, the tail clip 7 supports the cable to prevent the cable from bending excessively and affecting the sealing effect.

[0040] The outer shielding ring 3 and the inner shielding ring 4 clamp and press the shielding layer of the shielded cable into it. The outer shielding ring 3 also contacts the annular spring at the tail of the shielding cover 10 to form cable-plug shielding conduction. After the spring at the bottom of the shielding cover is installed, it contacts the customer's enclosure mounting interface 15 to form plug-customer enclosure shielding conduction, realizing connector shielding chain conduction.

[0041] The cable core is pressed into the tail of the power socket 2, and the spring clip at the head of the power socket 2 is clamped on the power plug 12 to form a plug power conduction; the power plug 12 is inserted into the solder plate socket 16 to form a plug-client power conduction.

[0042] like Figure 3 As shown, the plug housing 1 and the customer enclosure mounting interface are fixed together using two locking screw assemblies 14. The locking screw assembly 14 can be the screw assembly that comes with the plug housing or the screw assembly that is installed later, making the mating more secure and reliable.

[0043] like Figure 1 As shown, the power insert 12 is limited by the side protrusion against the mounting plate 11, and the power insert 12 is further secured to the mounting plate 11 by the interference barbs to prevent the power insert from dislodging.

[0044] like Figure 2 As shown, the power socket 2 is inserted into the plug housing 1, and the mounting plate of the power socket 2 is fixed in the predetermined slot of the mounting plate 11 to complete the primary locking of the power terminal. The cable sealing baffle 5 abuts against the outer shielding ring 3, preventing the part of the cable front end that is pressed against the power socket 2, the outer shielding ring 3, and the inner shielding ring 4 from retraction, thus forming a secondary locking of the power socket. After the power socket 2 is assembled, its head spring contacts the power plug 12 to form power conduction, and its square head abuts against the side protrusion of the power plug 12, preventing the power plug from retracting, thus forming a secondary locking of the power plug. The secondary locking mechanism of the terminal makes the terminal fixation more stable and can be used in higher levels of vibration conditions and more complex operating environments.

[0045] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
