Description

Technical Field

[0001] The utility model relates to the technical field of aviation plugs, in particular to an aviation plug which is convenient for welding. Background Art

[0002] Aviation plug is a popular name for electrical connectors, also known as aviation connectors and aviation electrical connectors. It is named because it was originally used in the aviation field. It is usually used with aviation sockets. The shell material is usually made of magnesium-aluminum alloy, stainless steel, etc., which is strong and durable.

[0003] Existing aviation plugs are generally composed of a plug and a socket. The circuit is connected and disconnected by plugging and separating the plug. The connection between the cable and the plug is fixed to the terminal post by an electric soldering iron. When soldering, it is necessary to hold the aviation plug in one hand and the cable in the other hand, align the tinned end of the cable core with the terminal post, and then solder it to the terminal post with an electric soldering iron.

[0004] However, when welding, it is necessary to first adjust the tinned end of the cable core and the terminal to the appropriate position before welding. If there is a slight movement, the tinned end of the core will be detached from the terminal and needs to be readjusted, which increases the time cost of wiring and affects the assembly efficiency of the aviation plug.

[0005] Based on this, the utility model designs an aviation plug which is easy to weld to solve the above problems. Utility Model Content

[0006] The utility model aims to provide an aviation plug which is convenient for welding, so as to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: the terminal includes a wire pressing part and a welding part, and the inner wall of the wire pressing part is fixedly provided with a spring sheet, and when the tinned end of the core of the cable wire enters the wire pressing part, the spring sheet presses against the tinned end of the core of the cable wire.

[0008] By adopting the above technical solution, when welding, the core of the cable is aligned with the terminal and pressed in. After the tinned end of the core enters the wire pressing part, it is pressed against the spring sheet in the wire pressing part. The spring sheet presses the tinned end against the inner wall of the pressing part, so that the tinned end will not be easily separated from the terminal. Then, an electric soldering iron is used to solder it to the welding part, which reduces the time for re-adjusting the angle of the core and improves the assembly efficiency of the aviation plug.

[0009] Preferably, the inner wall of the line pressing portion is provided with anti-slip convex patterns.

[0010] By adopting the above technical solution, the friction force of the inner wall of the wire pressing part is increased, so that the tin-immersed end of the wire core is less likely to be separated from the wire pressing part when it is pressed tightly.

[0011] Preferably, a base is fixedly arranged on the plug body, a limiting groove is formed in the base, a sliding block is arranged on the wiring post, and the sliding block is slidably connected with the limiting groove.

[0012] By adopting the above technical solution, the wiring post is rotatably connected to the base, and when welding wires, the opening direction of the wire welding part can be adjusted by rotating the wiring post, without re-adjusting the position of the aviation plug, making the welding more convenient.

[0013] Preferably, a convex block is arranged on the outer wall of the wiring post.

[0014] By adopting the above technical solution, the convex block is toggled to rotate the wiring post, making the rotation of the wiring post more labor-saving.

[0015] Preferably, a wire blocking ring is arranged at the top of the wiring post. When the tinned end of the wire core of the cable wire is located in the wire pressing part, the wire skin on the wire core abuts against the wire blocking ring.

[0016] By adopting the above technical solution, when the tinned end is inserted into the wire pressing part, the wire blocking ring separates the wire skin from the tinned end, preventing the temperature of the soldering iron from burning the wire skin and affecting the safety of the wire use.

[0017] In summary, the present application has the following beneficial technical effects: During welding, the wire core of the cable wire is aligned with the wiring post and then pressed in. After the tinned end of the wire core enters the wire pressing part, it abuts against the elastic piece in the wire pressing part, and the elastic piece presses the tinned end tightly against the inner wall of the pressing part, so that the tinned end will not easily break away from the wiring post. Then, a soldering iron is used to weld it on the welding part, reducing the time for re-adjusting the angle of the wire core and improving the assembly efficiency of the aviation plug.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The following will be further described in detail with reference to the attached Figures 1-3 This application will be further described in detail.

[0027] An aviation plug convenient for welding includes a plug body 4, a terminal 3, and a cable 1 welded to the terminal 3. The terminal 3 includes a pressing part 35 and a welding part 32. An elastic piece 33 is fixedly arranged on the inner wall of one side of the pressing part 35, and an anti-slip convex pattern 36 is arranged on the other side. The anti-slip convex pattern 36 abuts against the elastic piece 33.

[0028] During welding, the core 2 of the cable 1 is aligned with the terminal 3 and then pressed in. The tinned end 21 of the core 2 enters the pressing part 35 from the welding part 32. The tinned end 21 pushes the elastic piece 33 in the pressing part 35 downward until it enters between the elastic piece 33 and the anti-slip convex pattern 36. The self-return elasticity of the elastic piece 33 presses the tinned end 21 tightly against the anti-slip convex pattern 36, so that the tinned end 21 will not easily break away from the terminal 3. Then, a soldering iron is used to weld it to the welding part 32, avoiding readjustment due to the breakaway of the core 2, reducing the welding time, and improving the assembly efficiency of the aviation plug.

[0029] The inner wall of the pressing part 35 is provided with an anti-slip convex pattern 36, which is located on the side opposite to the elastic piece 33. A base 5 is fixedly arranged on the plug body 4, a limiting groove 51 is opened on the base 5, a slide block 37 is arranged on the terminal 3, the slide block 37 is slidably connected with the limiting groove 51, a bump 34 is arranged on the outer wall of the terminal 3, and a wire blocking ring 31 is arranged on the top of the terminal 3.

[0030] Before soldering, first adjust the direction of the plug body 4 and place it on the tabletop. Then insert the tinned end 21 of the wire core 2 of the cable 1 into the wire pressing part 35 to abut against the elastic piece 33. The anti-slip convex stripes 36 on the inner wall help to increase the friction force, making the tinned end 21 less likely to break away from the wire pressing part 35, and the tinned end 21 is limited in the terminal 3. At this time, the wire sheath on the wire core 2 is pressed against the wire blocking ring 31, and the wire blocking ring 31 separates the wire sheath from the welding part 32, which can avoid the accidental contact of the soldering iron with the wire sheath during soldering and prevent the wire sheath from being damaged. If the orientation of the welding part 32 is not conducive to soldering before soldering, the convex block 34 can be toggled to make the terminal 3 rotate. The slider 37 on the terminal 3 slides in the limit groove 51 until the welding part 32 rotates to the required position, and then soldering is carried out.

[0031] The implementation principle of this embodiment is: first adjust the direction of the plug body 4 and place it on the tabletop. During soldering, align the wire core 2 of the cable 1 with the terminal 3 and press it in. The tinned end 21 of the wire core 2 enters the wire pressing part 35 from the welding part 32. The tinned end 21 pushes the elastic piece 33 in the wire pressing part 35 downward until it enters between the elastic piece 33 and the anti-slip convex stripes 36. The self-returning force of the elastic piece 33 presses the tinned end 21 tightly against the anti-slip convex stripes 36, making the tinned end 21 not easily break away from the terminal 3. If the orientation of the welding part 32 is not conducive to soldering, the convex block 34 can be toggled to make the terminal 3 rotate. The slider 37 on the terminal 3 slides in the limit groove 51 until the welding part 32 rotates to the required position, and then use a soldering iron to solder it on the welding part 32, avoiding readjustment due to the detachment of the wire core 2, reducing the adjustment time before soldering, and improving the assembly efficiency of the aviation plug.
