DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] For example, Figures 1-6As shown, the utility model provides a kind of card line fixed plug, mainly for double foot plug use, the main structure of entire plug includes shell 1, wire body 2 and two prongs 3, shell 1 is insulating plastic shell, can encapsulate internal structure and carry out the preservation to its internal structure.Two prongs 3 are inserted in the shell same side, form two external power connection end, simultaneously with wire body 2 connection is also the connection end of plug internal neutral wire and live wire.

[0023] One end of two prongs 3 is inserted into shell 1 and is in the form of an "eight" structure, shell 1 is provided with a corresponding jack 17, and a limiting block 14 for fixing the prong 3 is provided on both sides of the jack 7. When the prong 3 is inserted, the limiting block 14 can increase the contact area on both sides of the prong 3, effectively enhancing the fixation of the prong 3. In order to further enhance the stability of the prong 3, a raised anti-slip part 15 is additionally provided on both sides of the prong 3. The anti-slip part 15 slides synchronously when the prong 3 is inserted into the jack 17 between the two limiting blocks 14. Finally, the anti-slip part 15 is embedded into the limiting block 14 to contact the inside, enhancing the fixation and preventing the prong 3 from sliding in the jack 17.

[0024] One end of the prong 3 is inserted into the shell 1, in order to better connect with the wire body 2, the two are directly clamped and fixed, which is convenient for connection and avoids falling off. One end of the two prongs 3 is provided with a clamping hole 4, the size of the clamping hole 4 is the same as the size of the battery core 6 inside the wire body 2, so that the entire battery core 6 can be smoothly fixed in the clamping hole 4 and will not fall off. At the same time, a sliding groove 5 is provided between the clamping hole 4 and the outer side of the prong 3, which is in communication with the clamping hole 4. When connecting, the battery core 6 can be directly dropped into the clamping hole 4 at the end through the sliding groove 5. In order to avoid the battery core 6 assembled in the clamping hole 4 from falling off from one end of the sliding groove 5, the opening of the sliding groove 5 connected to one end of the clamping hole 4 is smaller than the maximum width of the clamping hole 4, that is, smaller than the outer diameter of the battery core 6.

[0025] When the wire body 2 is connected to the inside of the shell 1, the inside of the wire body 2 is composed of two battery cores 6, so that the two battery cores 6 can be connected to different prongs 3 to form live wire and neutral wire. After the battery core 6 is fixed in the corresponding clamping hole 4, a raised insulating block 7 is provided at the end of the battery core 6 to prevent the battery core 6 from falling off after being pulled in the clamping hole 4. The entire connection structure is convenient and fast, and the battery core 6 will not fall off after being connected to the prong 3, and does not need to be fixed by welding.

[0026] It needs to be explained that the side of the shell 1 inserted with the plug pin 3 is provided with a protruding clasp 8, the plug pin 3 is fixed inside the clasp 8, and the clasp 8 is convenient for fixing the connecting piece connected with the plug. Four protruding clamping blocks 9 are arranged on the inner wall of the clasp 8. When the connecting piece is connected with the plug, the contact part can be rotated to be fixed below the clamping block 9, so as to avoid falling off. In order to avoid deformation or damage of the plug pin 3 caused by rotation, a first hollow part 10 is arranged at the position of the shell 1 inserted with the plug pin 3, which semi-surrounds the plug pin 3. The first hollow part 10 can allow the position of the shell 1 inserted with the plug pin 3 to be slightly deformed to fix the connecting piece connected with the plug, and does not affect the connection with the plug pin 3, and even will not damage the plug pin 3.

[0027] The surface of the shell 1 is also provided with a protruding locking block 11 and a second hollow part 12 semi-surrounding the locking block 11. The locking block 11 is provided with a pressing part 13 extending outwardly from the clasp 8. The locking block 11 can prevent the connecting piece from being rotated in the opposite direction after being rotated, and further fix the stability of the connecting piece. When it is necessary to disassemble the connecting piece, the user needs to press the pressing part 13 downwardly with the hand to make the protruding part disengage, and then rotate the connecting piece to disassemble.

[0028] In addition, when the wire body 2 extends in and out of the shell 1, a wire protection sleeve 16 is arranged at the connection position of the shell 1 and the wire body 2. The wire body 2 extends outwardly through the middle part of the wire protection sleeve 16. The wire protection sleeve 16 avoids abrasion of the wire body 2 at the contact position of the shell 1, and protects the wire body 2 from being easily broken, thereby reducing the damage to the wire body 2.

[0029] Compared with the traditional technology, when the internal wire body 2 is connected with the plug pin 3, the part of the electric core 6 of the wire body 2 is directly clamped into the corresponding clamping hole 4 of the plug pin 3 for fixation. After the wire body 2 is clamped, the wire body 2 and the plug pin 3 will not fall off after being connected, the assembly is convenient, and the stability is good. At the same time, the connection between the two does not need to be fixed by welding, thereby avoiding direct damage of the shell 1 caused by high-temperature welding.

[0030] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, 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 scope of the equivalent elements of the claims should be included in the present application, and any figure reference in the claims should not be regarded as limiting the claims.
