[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0035] This application discloses an RCA socket with detection function. (Refer to...) Figure 1 and Figure 2 An RCA socket with detection function includes a shielding shell 4, a plastic body 41, a signal pin 1 and a switch spring 2. The shielding shell 4 covers the plastic body 41 so that the shielding shell 4 and the plastic body 41 enclose to form a mounting cavity 42. The signal pin 1 and the switch spring 2 are installed in the mounting cavity 42.
[0036] Reference Figure 3A slot 11 for inserting a pin is formed on signal pin 1. The slot 11 extends through the thickness of signal pin 1 and extends along the extension direction of signal pin 1. The inner wall of the slot 11 abuts and clamps the pin for conduction. The pin is inserted into the slot 11 along the opening direction of the slot 11. The opening surface of the slot 11 is defined as an opening plane parallel to the opening direction of the slot 11. The end of the switch spring 2 abuts against the signal pin 1 to conduct electricity and form a circuit. An insulating seed 3 is snapped onto the end of the switch spring 2. The insulating seed 3 is made of insulating material and is used to abut against the pin inserted into the slot 11. The pin pushes the insulating seed 3, pushing the switch spring 2 away from the signal pin 1, thereby breaking the circuit between the switch spring 2 and the signal pin 1.
[0037] Reference Figure 3 Two protrusions 21 are fixedly connected to the switch spring 2. The extending direction of the protrusions 21 is parallel to the direction in which the pin pushes the insulating seed 3. The two protrusions 21 are located on the side wall of the signal pin 1 around the opening surface of the slot 11. The two protrusions 21 abut against the side wall of the signal pin 1 on both sides of the opening surface of the slot 11 with the opening direction of the slot 11 as the central axis. The protrusions 21 are integrally formed with the switch spring 2. Both the switch spring 2 and the signal pin 1 are made of conductive metal and have a certain degree of toughness.
[0038] Reference Figure 4 and Figure 5 An installation groove 32 for inserting the switch spring 2 is provided on the side wall of the end of the insulating seed 3. The installation groove 32 does not penetrate the insulating seed 3. A retaining groove 33 is provided on the outer side wall of the insulating seed 3. The retaining groove 33 communicates with the installation groove 32, and the opening direction of the retaining groove 33 is perpendicular to the opening direction of the installation groove 32. A U-shaped through-cut is made on the side wall of the switch spring 2, and then the U-shaped cut is bent outward. The convex part is the retaining strip 22. The recess formed between the retaining strip 22 and the switch spring 2 is the groove 23. The position where the retaining strip 22 connects to the switch spring 2 is in the middle of the retaining groove 33, so that the end of the retaining strip 22 that is furthest from its connection with the switch spring 2, that is, the end of the retaining strip 22 that protrudes from the switch spring 2, abuts against the inner wall of the retaining groove 33 closest to the opening of the installation groove 32, so as to prevent the switch spring 2 from exiting the installation groove 32.
[0039] Reference Figure 4 An insulator 3 has a guide slope 31 formed on the outer sidewall facing the signal pin 1. The guide slope 31 is inclined in the direction that is closer to the opening of the mounting groove 32 than the signal pin 1. The guide slope 31 is used to abut the pin when it is inserted into the slot 11 and to guide the insulator 3 away from the slot 11.
[0040] Reference Figure 2The shielding shell 4 is provided with a female plug assembly 43 for electrically connecting the male plug pin, the female plug assembly 43 comprising a grounding copper sleeve and a color ring, and a slot hole is further formed in the shielding shell 4 for inserting the pin into the plug slot 11. The plastic main body 41 is fixedly connected with a clamping block 44, and a through slot 45 is formed in the shielding shell 4 for inserting and clamping the clamping block 44.
[0041] The implementation principle of the RCA socket with the detection function is as follows: when the pin is not inserted, the protrusion 21 is abutted against the signal pin 1 under the self elastic force of the switch elastic sheet 2, forming a switch circuit; when the pin is inserted, the pin body first abuts against the guide slope 31, and the pin drives the insulating seed 3 to move away from the plug slot 11 through the guidance of the guide slope 31, so as to drive the switch elastic sheet 2 to bend and deform away from the plug slot 11, and make the protrusion 21 separate from the signal pin 1; at this time, the switch circuit between the switch elastic sheet 2 and the signal pin 1 is disconnected, so that the host computer obtains a disconnected signal, indicating that the pin is inserted at this time, and the audio and video signals are output.
[0042] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
