DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present application.

[0027] Please refer to Figures 1-3 , a four-plug high-definition transmission connector, comprising an insulating seat 1, a terminal 2 and a shell 3;

[0028] The insulating seat 1 is provided with a tongue plate 11, the terminal 2 is assembled with the insulating seat 1, and the contact end of the terminal 2 is located on the tongue plate 11, and the pin end is led out from the rear end of the insulating seat 1;

[0029] The shell 3 is sleeved on the insulating seat 1, and the lower end of the shell 3 is provided with four pins 31;

[0030] The shell 3 is provided with a grounding spring sheet 4, the grounding spring sheet 4 comprises an upright piece 41, bent pieces 42 connected to both sides of the upright piece 41, and blocking pieces 43 on the bent pieces 42, and the two bent pieces 42 are inclined and expanded to the opposite side with the upright piece 41 as the starting point, forming a "V" shaped structure.

[0031] Specifically, the outer shell 3 is a housing with openings at the front and rear, which is sleeved outside the insulating base 1 to avoid affecting the insertion of the external connection male head and the connector. The pin ends of the terminals 2 are led out from the rear end of the insulating base 1. During mounting, the pins of the terminals 2 are welded and fixed to the solder joints, and at the same time, the four pins 31 at the lower end of the outer shell 3 are inserted into the reserved sockets on the circuit board to improve the overall firmness of the connector. The contact ends of the terminals 2 are located on the tongue plate 11, which is also used for electrical connection with the plug during insertion;

[0032] In the grounding spring piece 4 composed of the upright piece 41, the bent piece 42 and the retaining piece 43, when the circuit board with the connector mounted is assembled and used on the device, the two bent pieces 42 can be pressed towards the middle to cause deformation, then the retaining piece 43 is passed through the opening on the chassis, and then the two bent pieces 42 are released to make the two bent pieces 42 elastically recover. At this time, the retaining piece 43 expands outwards to resist the chassis, thus forming a connection mode of mutual abutment with the chassis, and further providing an additional fixing force when the connection male head and the connector are inserted, so as to avoid the connector from retreating when the connection male head and the connector are inserted, improve the firmness, and ensure the stability of the connector during daily use;

[0033] At the same time, the grounding spring piece 4 is integrally made of a material with good conductivity, such as phosphor bronze or beryllium copper, and is treated with gold plating or tin plating on the surface to improve the corrosion resistance. During the signal transmission process of the connector, the grounding spring piece 4 contacts with the chassis to form a grounding connection, and the chassis is usually used as the main grounding plane of the device. After being connected through the grounding spring piece 4, a good electrical connection is formed between the connector outer shell and the chassis, constructing a complete shielding path to effectively reduce the influence of external electromagnetic interference on signal transmission and improve the stability of signal transmission.

[0034] In this embodiment, referring to Figure 1 and Figure 2 , it is further proposed that a clamping plate 5 is connected to the grounding spring piece 4, and the clamping plate 5 is clamped on the outer shell 3 in a "冖" - shaped structure.

[0035] Specifically, by clamping the clamping plate 5 on the outer shell 3, the grounding spring piece 4 is fixedly connected to the outer shell 3, and the two sides of the clamping plate 5 can be elastically deformed, so that by pulling the grounding spring piece 4 upwards with force, the disassembly can be completed. The design of flexible disassembly enables it to adjust the position of the grounding spring piece 4 on the outer shell 3 according to different chassis structures to adapt to different chassis.

[0036] Furthermore, both sides of the lower end of the clamping plate 5 have arc - shaped portions 51 with arc - shaped transitions; the setting of the arc - shaped portions 51 can make both sides of the lower end of the clamping plate 5 better receive force and expand outwards when the clamping plate 5 is installed on the outer shell 3, which is convenient for use.

[0037] Further, the hollow 44 is arranged at the bending transition of the bending piece 42 and the vertical piece 41, which can reduce the bending stiffness, so that the bending piece 42 can be easily elastically deformed when subjected to external force, and can quickly restore to the original state after the force is removed.

[0038] In the embodiment, referring to Figure 1 and Figure 2 , the upper end surface of the shell 3 is further attached with the Mylar sheet 6.

[0039] Specifically, the Mylar sheet 6 can be used for different SMT equipment, that is, a plane is established on the upper end surface of the shell 3, so that the SMT patch equipment can easily and accurately complete the suction action, without frequent debugging, thereby improving the production efficiency and accuracy; and the Mylar sheet 6 has certain buffering performance, thereby reducing the damage to the connector during patching.

[0040] In the embodiment, referring to Figure 2 and Figure 3 , the lower end of the shell 3 is further provided with the bottom sheet 7, the lower end of the bottom sheet 7 is provided with the positioning column 71, and the bottom sheet 7 is made of insulating material.

[0041] Specifically, the positioning column 71 at the lower end of the bottom sheet 7 is inserted into the positioning hole reserved on the circuit board, and the bottom sheet 7 is tightly attached to the circuit board to isolate the shell 3, thereby improving the overall insulation and ensuring the safety of the circuit.

[0042] Further, the lower end of the insulating seat 1 is provided with the clamping hole 12, and the upper end of the bottom sheet 7 is provided with the clamping block 72 corresponding to the clamping hole 12, the bottom sheet 7 is fixed at the bottom of the connector by the mutual clamping of the clamping block 72 and the clamping hole 12, thereby avoiding the accidental falling of the bottom sheet 7.

[0043] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced therein. Any reference signs in the claims should not be considered as limiting the claims involved.
