[0003] RCA interfaces are widely used between various audio and video devices, especially in home theater systems. They are often used to connect devices such as DVD players and game consoles to TVs or audio systems. Due to its "lotus head" design, the RCA interface is particularly convenient and intuitive when connecting to a home theater system. However, when using existing RCA interfaces, the plug structure and injection molding position are not robust enough. When dealing with different sizes of plug-in components, the metal casing is easily pulled off during insertion and removal. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-pull-out structure to solve the problem mentioned in the background art that when the RCA interface is used, its plug structure and injection molding position are not firm enough, and the metal shell is easily pulled out during the insertion and removal process when dealing with different specifications of fittings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-pull-out structure, comprising a first connector and a second connector, wherein a connecting block is fixedly connected to the surface of the first connector, a buckle is fixedly connected to the surface of the connecting block, a first plastic part is provided on the surface of the first connector, a slot is formed on the surface of the first plastic part, a fastening ring is fixedly connected to the surface of the second connector, and a second plastic part is sleeved on the surface of the second connector.

[0006] Preferably, the connecting blocks are evenly distributed in four groups on the surface of the first connector, and the buckles are evenly distributed in four groups on the surface of the connecting blocks.

[0007] Preferably, the slots are evenly distributed in four groups on the surface of the first plastic part.

[0008] Preferably, the connecting block is connected by surface mating of the first connector and the slot.

[0009] Preferably, the buckle is connected to the inside of the first plastic part by abutting through a slot.

[0010] Preferably, the first plastic part is fixedly connected to the surface of the first connector by a snap fastener.

[0011] Preferably, the second plastic part is connected by the surface abutment of the fastening ring and the second connector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By connecting the first connector and the first plastic part, the first plastic part is installed on the surface of the first connector. The amplitude of the flared opening of the first connector is increased, the contact area between the first plastic part and the first connector is increased, and the adhesion is enhanced. Then, by connecting the connecting block and the slot, and connecting the buckle and the slot, the connecting block drives the buckle to insert into the slot, thereby securing the first plastic part and fixing the installation position of the first connector and the first plastic part, so as to prevent the first connector from being pulled off during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] An anti-pull-out structure includes a first connector 1 and a second connector 6. The first connector 1, the first plastic part 4, the second connector 6, and the second plastic part 8 are all existing products and are not considered as technical protection points of this application. They will not be described in detail here. A connecting block 2 is fixedly connected to the surface of the first connector 1 for connecting a buckle 3. A buckle 3 is fixedly connected to the surface of the connecting block 2 for snapping into the slot 5. A first plastic part 4 is provided on the surface of the first connector 1. A slot 5 is opened on the surface of the first plastic part 4 for snapping into the buckle 3. A fastening ring 7 is fixedly connected to the surface of the second connector 6 to improve the tightness of the connection between the second connector 6 and the second plastic part 8. A second plastic part 8 is sleeved on the surface of the second connector 6.

[0024] Furthermore, the connecting blocks 2 are evenly distributed in four groups on the surface of the first plug-in 1, and the buckles 3 are evenly distributed in four groups on the surface of the connecting blocks 2. The four groups of connecting blocks 2 are used to improve the tightness of the connection between the first plug-in 1 and the first plastic part 4, and the four groups of buckles 3 are used to improve the snapping strength between the buckles 3 and the slots 5.

[0025] Furthermore, the slots 5 are evenly distributed in four groups on the surface of the first plastic part 4. The four groups of slots 5 are used to connect the four groups of connecting blocks 2, which not only provide guidance for the connection between the first plug-in 1 and the first plastic part 4, but also improve the tightness of the connection.

[0026] Furthermore, the connecting block 2 is connected by the surface mating of the first connector 1 and the slot 5, and the first plastic part 4 is inserted into the surface of the first connector 1, so that the connecting block 2 is inserted into the slot 5, thereby allowing the buckle 3 to be inserted into the slot 5.

[0027] Furthermore, the buckle 3 is connected to the first plastic part 4 by the internal abutment of the slot 5. The buckle 3 is inserted into the slot 5 by deformation and then returns to its original shape to abut against the slot 5, thereby fixing the connection between the first connector 1 and the first plastic part 4.

[0028] Furthermore, the first plastic part 4 is fixedly connected to the surface of the first connector 1 by the buckle 3. The first plastic part 4 is installed on the surface of the first connector 1, so that the buckle 3 is engaged into the inside of the slot 5, thereby fixing the first plastic part 4 to the surface of the first connector 1 and preventing the first connector 1 and the first plastic part 4 from being pulled apart.

[0029] Furthermore, the second plastic part 8 is connected to the surface of the second plug-in part 6 by the fastening ring 7, so that the second plastic part 8 is fully in contact with the fastening ring 7, and the deformation of the second plastic part 8 abuts against the surface of the second plug-in part 6, thereby increasing the interference force between the second plug-in part 6 and the second plastic part 8 and preventing the second plug-in part 6 and the second plastic part 8 from being pulled apart.

[0030] Working principle: When using the first connector 1, the first plastic part 4 is first inserted into the surface of the first connector 1, so that the connecting block 2 is inserted into the slot 5, thereby allowing the buckle 3 to be inserted into the slot 5. The buckle 3 is inserted into the slot 5 through deformation, and then returns to its original shape to abut against the inside of the slot 5, thereby fixing the connection between the first connector 1 and the first plastic part 4. Then, the second plastic part 8 is sleeved on the surface of the second connector 6, so that the second plastic part 8 is in full contact with the fastening ring 7. The deformation of the second plastic part 8 abuts against the surface of the second connector 6, thereby increasing the interference force between the second connector 6 and the second plastic part 8, preventing the second connector 6 and the second plastic part 8 from being pulled apart.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
