Description

Technical Field

[0001] The utility model relates to the technical field of AV seats, in particular to an AV seat structure capable of installing a PCB. Background Art

[0002] Composite video interface (abbreviated as AV socket) is the most common audio and video interface, and almost all TV sets and DVD players have this interface. Among them, the three-hole AV socket is composed of a PBT plastic base, a PBT plastic foot (with hook), a foot handle, a PBT plastic color ring, a copper sleeve and a brass terminal (there are 6 terminals in total).

[0003] When the AV socket is inserted into the circuit board (i.e., PCB), all six terminals are inserted into the connection slots on the PCB. In order to fix the AV socket on the PCB, the existing AV socket has a plastic foot with a hook on both sides, which is inserted into the PCB to fix it (at this time, two holes need to be opened on the PCB so that the plastic feet can match it). The distance between the two openings on the PCB cannot be longer or shorter than the distance between the two plastic feet, otherwise it cannot play a fixing role. Therefore, it is difficult to grasp the position of the openings, and the insertion operation is complicated. At the same time, the terminals on the existing AV socket are all exposed to the outside, which can easily cause the terminals to be bumped or contaminated during transportation and storage, resulting in connection failure. To this end, we propose an AV socket structure that can be installed with a PCB. Utility Model Content

The two internal threaded rings 8 are symmetrically fixedly connected at the front edge of the upper end of the AV seat body 1, and the two arc grooves 7 are respectively opened at the upper end of the AV seat body 1 corresponding to the two internal threaded rings 8; specifically, the setting of the two internal threaded rings 8 and the two arc grooves 7 can facilitate the installation of the AV seat body 1 more firmly with the help of screws (the staff can choose whether to use them according to the actual installation situation).

[0023] See also Figure 1 , Figure 2 and Figure 4 In the figure, the protective cover 2 is made of PBT plastic material; specifically, the protective cover 2 made of PBT plastic material has high rigidity and hardness, good heat resistance and good protective effect.

[0024] Working principle: Since the three first terminals 9 and the three second terminals 10 are all located in the protective cover 2, they can be prevented from being bumped and contaminated during transportation and storage. When in use, the protective cover 2 can be opened.

[0025] The specific operation method for opening the protective cover 2 is: first, pull the pulling block 4 outward, the pulling block 4 will drive the limiting column 11 to slide outward in the inner walls of the transverse tube 5 and the connecting plate 3, the limiting column 11 will drive the annular plate 12 to slide in the transverse tube 5 (in this process, the spring 13 between the annular plate 12 and the transverse tube 5 will be squeezed on the outer wall of the limiting column 11), and the limiting column 11 will also slide outward in the inner wall of the second plug hole 14 on the AV seat body 1, until the limiting column 11 completely slides away from the second plug hole 14, and then turn the pulling block 4 forward while pulling the pulling block 4 without letting go, and the pulling block 4 It will drive the cross tube 5 to rotate, and the cross tube 5 will drive the connecting plate 3 to rotate on the protective cover 2 until the limiting column 11 completely leaves the second socket 14, and then the protective cover 2 is rotated backward by ninety degrees, and the protective cover 2 is rotated backward by ninety degrees on the AV seat body 1, and then the pulling block 4 is pulled outward again, and at the same time, when the pulling block 4 is rotated in the opposite direction so that the limiting column 11 corresponds to the first socket 6 on the AV seat body 1, the pulling block 4 is released, and under the action of the spring 13, the limiting column 11 will automatically reset and be inserted into the first socket 6, and the protective cover 2 can be opened and maintained in a fixed state.

[0026] The AV seat body 1 can then be inserted into the PCB. Since the three first terminals 9 and the three second terminals 10 are respectively V-shaped and fishhook-shaped, the adjacent first terminals 9 and second terminals 10 are inserted into the connecting grooves on the PCB together, the adjacent first terminals 9 and second terminals 10 fit each other, and the first terminals 9 and the second terminals 10 have a certain toughness. Therefore, the AV seat body 1 is inserted and fixed on the PCB with a good effect, and the insertion operation is simple and labor-saving, and there is no need to open two additional holes in the PCB.
