Technical Field

[0001] This application relates to the field of welding technology, specifically to a wire welding sleeve. Background Technology

[0002] Commonly used wire welding methods include: 1. Direct butt welding: directly butt two cables together and then apply solder; 2. Stranded wire welding: twist two cables together and then weld them; 3. Sleeve crimping: using a metal sleeve for crimping and then welding.

[0003] The above welding methods often have the following problems: 1. Unstable welding quality, prone to incomplete welds; 2. Irregular weld appearance with burrs; 4. Insufficient welding strength, prone to breakage. Utility Model Content

[0023] Reference Figure 1A wire welding sleeve 1, wherein one or more welding holes 2 are provided on the side wall of the welding sleeve 1, and two barb areas are provided on both sides of the welding holes 2 on the inner wall of the welding sleeve 1.

[0024] Among them, the barbs 3 in one barb area are arranged facing each other with the barbs 3 in another barb area.

[0025] Specifically, during welding, it should first be confirmed that the diameter of the wire to be welded is smaller than the inner diameter of the welding sleeve 1. The two wires to be welded are inserted into the welding sleeve 1 from both ends, and the two ends of the wires to be welded are joined at the welding hole 2. It can be observed through the welding hole 2 that the ends of the two wires have been joined. Traditional winding welding methods have high requirements for welding process, and it is necessary to control the solder at the joint to be smooth and flat, and not to form sharp points, otherwise it will puncture the heat shrink sleeve and affect the insulation at the joint. In this application, the welding liquid can be injected into the welding sleeve 1 through the welding hole 2, so that the wire core and the welding sleeve 1 are fully welded. The welding liquid is inside the welding sleeve 1, which has low requirements for welding process, is not easy to form sharp points, and is unlikely to have an adverse effect on the heat shrink sleeve. In the actual welding process, in order to perform the welding, the conductor and core should be treated first. If the conductor has an outer sheath, the outer sheath should be stripped to expose about half the length of the bare core of the welding sleeve 1. The oxide layer and dirt on the exposed part of the core should also be removed. The two conductors are inserted into the welding sleeve 1 from both ends respectively, and the connection of the conductor ends is observed through the welding hole 2. Since the inner wall of the welding sleeve 1 is provided with opposing barbs 3, it will not obstruct the conductor when it is inserted. After the conductor is inserted, the barbs 3 can prevent the conductor from being pulled out. It should be noted that, referring to Figure 2 The two barbed areas inside the welding sleeve 1 are arranged facing each other and opposite to the direction of wire insertion, thus preventing the wire from being pulled out after insertion. By providing the barbed areas, on the one hand, the two wire sections can be easily joined together during welding, facilitating the subsequent injection of welding fluid into the welding sleeve 1 through the welding hole 2; on the other hand, it can improve the welding strength to a certain extent after welding, enhancing the tensile strength of the wire. It is understood that if heat-shrink tubing is to be used ultimately, a heat-shrink tubing slightly longer than the welding sleeve 1 needs to be pre-fitted onto the wire.

[0026] Reference Figure 1 It is understood that at least one weld hole 2 is located in the middle of the weld sleeve 1.

[0027] Specifically, when the welding sleeve 1 has only one welding hole 2, the welding hole 2 is located in the middle of the welding sleeve 1. Positioning the welding hole 2 in the middle of the welding sleeve 1 allows the welding molten metal to flow from the middle of the welding sleeve 1 to both ends during welding, thus ensuring that the welding length of the two conductors within the welding sleeve 1 is consistent, guaranteeing the overall welding strength and quality. When the welding sleeve 1 has more than one welding hole 2, at least one welding hole 2 is located in the middle of the welding sleeve 1. Furthermore, the multiple welding holes 2 can be located at different parts of the welding sleeve 1, allowing welding molten metal to be injected through the welding holes 2 at different locations, ensuring thorough welding between the conductor and the welding sleeve 1.

[0028] It is understood that a tin-plated layer is provided on the inner wall of the welding sleeve 1.

[0029] Specifically, by setting a tin plating layer inside the welding sleeve 1, the adhesion of solder to the inner wall of the sleeve can be improved. Obviously, setting a tin plating layer on the inner wall of the welding sleeve 1 requires pretreatment of the inside of the welding sleeve 1.

[0030] It is understood that the thickness of the tin plating layer is 3-5 μm.

[0031] It is understood that the welding sleeve 1 has a cylindrical structure.

[0032] Specifically, since conductors are typically single-stranded or multi-stranded cylindrical structures, a cylindrical structure is more suitable for welding sleeve 1. Obviously, during welding, the inner diameter of the welding sleeve 1 should be larger than the diameter of the conductor core to be welded, ensuring that the conductor core passes through the welding sleeve.

[0033] It is understood that the welded sleeve 1 is of T2 copper or higher grade.

[0034] It is understood that the welding sleeve 1 is an aluminum tube.

[0035] Specifically, the copper of T2 grade or higher in the welding sleeve 1 of this application can be used for welding single-strand copper core wires and multi-strand copper core wires, and the aluminum tube can be used for welding single-strand aluminum core wires and multi-strand aluminum core wires.

[0036] How to use this application:

[0037] (1) Remove the outer sheath of the two wires to be welded, with the stripping length being close to half the length of the welding sleeve 1, and remove the oxide layer and dirt from the exposed part of the core wire;

[0038] (2) A heat shrink tubing longer than the welding sleeve 1 is fitted onto one section of the conductor;

[0039] (3) Insert the cores of the two conductors into the welding sleeve 1 from both ends of the welding sleeve 1, and observe the end connection of the two conductors through the welding hole 2.

[0040] (4) Place the solder in the solder hole 2 and melt the solder into molten tin with a soldering iron. Pour the molten tin into the welding sleeve 1 until it is full. The molten tin fully penetrates into the gap between the two wire cores and the inner wall of the welding sleeve 1, so that the two wire cores are fully welded to the welding sleeve 1.

[0041] (5) Move the heat shrink tubing to the welding sleeve 1 so that the heat shrink tubing completely covers the welding sleeve 1 and the wires at both ends, and heat the heat shrink tubing to shrink and tighten it.

The scope of protection of this application should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims.
