Description

Technical Field

[0001] This utility model relates to the field of DP sockets, and more specifically, to a DP socket with a grounding spring. Background Technology

[0002] The DisplayPort is a digital interface standard for video and audio transmission, and its structure is designed to support high-bandwidth, high-resolution signal transmission.

[0003] In Chinese utility model patent application CN202320840705.9, a DP connector socket is disclosed, comprising a housing, an insulating body, and upper and lower rows of terminals disposed within the insulating body. The upper row of terminals includes upper differential signal pairs, and the lower row of terminals includes lower differential signal pairs. The spacing between the fixing portions of the upper and lower differential signal pairs is smaller than the spacing between their contact portions. Furthermore, an EMI separator is disposed within the insulating body, located between the upper and lower rows of terminals, and spaced between the contact portions of the upper and lower differential signal pairs. This reduces crosstalk between adjacent upper / lower differential signal pairs and optimizes differential signal attenuation.

[0004] The existing technology has the following problems:

[0005] In existing technologies, most DP sockets use metal springs for clamping and limiting during insertion. In high-frequency use, this can easily lead to terminal displacement or contact failure, and the vibration resistance is low. Therefore, it is necessary to design a DP socket with a grounding spring. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a DP socket with a grounding spring to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A DP socket with a grounding spring includes an insulating shell, a connector body snapped into the inner wall of the insulating shell, a front terminal connected to the front end of the connector body, external fixing bolts on both sides of the insulating shell, and metal springs at the top and bottom of the insulating shell. Through the arrangement and cooperation of the external fixing bolts, internal fixing bolts, and metal springs, the internal fixing bolts can fix the front terminal, resulting in good stability between the front terminal, the connector body, and the insulating shell.

[0009] The external fixing bolt design allows for secure fastening of the external connector terminal by rotating the external fixing bolt. The DP socket with screw fastening structure is doubly locked by the metal spring and internal fixing bolt, capable of withstanding insertion and extraction forces greater than 50N, preventing terminal displacement or contact failure caused by high-frequency insertion and extraction. Compared to traditional snap-fit ​​designs, screw fastening improves the interface's vibration resistance by 30%, making it suitable for high-vibration environments such as industrial equipment and automotive applications.

[0010] Meanwhile, the 360° circumferential shielding structure of the spring and metal shell can suppress high-frequency crosstalk to below -60dB, meeting the anti-interference requirements of the DP2.1 protocol for 40Gbps high-speed signals;

[0011] The screws secure the outer casing to form a continuous conductive surface, which, together with the spring contacts, provides multi-point grounding, resulting in an electromagnetic shielding effectiveness of >85dB, which is superior to the 70dB level of screwless structures.

[0012] The insulating housing includes an outer metal housing, and the inner wall of the metal housing is covered with an insulating adhesive layer; by providing an insulating adhesive layer on the inner wall of the metal housing, short circuits between the metal housing and the front terminal can be avoided.

[0013] The inner wall of the insulating shell is provided with several internal fixing bolts, and one end of the internal fixing bolts is threaded into the connector body;

[0014] The metal spring is externally grounded at multiple points.

[0015] Preferably, the front terminal is snapped into the front end of the insulating housing.

[0016] Preferably, the outer wall of the insulating shell is movably connected to a dustproof protective cover via a short pin, and the outer wall of the dustproof protective cover is provided with a guide groove, which is configured to match the shape of the metal spring.

[0017] Preferably, the outer wall of the insulating shell is provided with positioning feet, and the number of positioning feet is multiple, and the multiple positioning feet are symmetrically arranged on both sides of the insulating shell;

[0018] A positioning post is provided at the bottom center of the insulating shell.

[0019] Preferably, the outer wall of the insulating shell is movably connected to a side plate, and an external positioning hole is provided at the center of the outer wall of the side plate.

[0020] Preferably, there are two external fixing bolts, and the two external fixing bolts are symmetrically arranged on both sides of the insulating shell, and the threads of the external fixing bolts extend into the insulating shell.

[0021] The beneficial effects of this utility model are as follows: 1. The DP socket with grounding spring is used in conjunction with the setting of external fixing bolts, internal fixing bolts and metal springs. The setting of internal fixing bolts can fix the front terminal, so that the front terminal has good stability with the connector body and the insulating shell.

[0022] The external fixing bolt design allows for secure fastening of the external connector terminal by rotating the external fixing bolt. The DP socket with screw fastening structure is doubly locked by the metal spring and internal fixing bolt, capable of withstanding insertion and extraction forces greater than 50N, preventing terminal displacement or contact failure caused by high-frequency insertion and extraction. Compared to traditional snap-fit ​​designs, screw fastening improves the interface's vibration resistance by 30%, making it suitable for high-vibration environments such as industrial equipment and automotive applications.

[0023] Meanwhile, the 360° circumferential shielding structure of the spring and metal shell can suppress high-frequency crosstalk to below -60dB, meeting the anti-interference requirements of the DP2.1 protocol for 40Gbps high-speed signals;

[0024] The screws secure the outer casing to form a continuous conductive surface, which, together with the spring contacts, provides multi-point grounding, resulting in an electromagnetic shielding effectiveness of >85dB, which is superior to the 70dB level of screwless structures.
