Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding machines, and in particular relates to an anti-loosening electric welding machine wiring kit. Background Art

[0002] Welding is a method of joining metal materials together and is widely used in various industries. It melts the metal surface to connect two or more metal parts to form an integral structure. Welding technology can be used in manufacturing, construction, aviation, automobiles, energy and other industrial fields. In the manufacturing industry, welding technology is one of the most widely used industries, mainly in the following aspects: Processing and manufacturing: Welding technology can be used for the connection and processing of various metal materials, such as steel, iron, aluminum, etc., for the manufacture of various mechanical parts, equipment casings, structural parts, etc. Repair and maintenance: Welding technology can also be used for the repair and maintenance of equipment, such as repairing worn parts, welding cracks, etc., to extend the service life of the equipment.

[0003] Welding technology can be divided into three categories: fusion welding, pressure welding, and brazing. In daily maintenance, fusion welding generally uses AC and DC welding machines, which are mainly composed of welding machines, grounding wires, and welding handle wires. After the electric current is passed through the welding machine, the grounding wire is overlapped with the workpiece, and the welding handle wire is used to clamp the welding rod to contact the workpiece to form a loop. The end of the welding rod is heated by the short-circuit current to melt the flux, making it connected to the metal parts as a whole.

[0004] like Figure 1 As shown, the existing electric welding machine wiring kit includes a terminal 3 and a wiring base 1, the bottom of the terminal is fixedly sleeved with an insulating rubber sleeve 2, and the middle of the wiring base is coaxially provided with a terminal plug hole and an insulating rubber sleeve plug hole. When connected, the terminal is coaxially inserted into the wiring base, wherein the terminal and the terminal plug hole are matched and sleeved (contact electrical connection), and the insulating rubber sleeve and the insulating rubber sleeve plug hole are matched and sleeved.

[0005] The disadvantage of the above connection method is that with the accumulation of use, the terminal is prone to melting and becoming smaller or the terminal socket is easily worn and enlarged, which may cause the terminal to loosen easily and cause poor contact, affecting the use status.

[0008] A wiring kit for an anti-loosening electric welding machine comprises a terminal and a terminal base, wherein an insulating rubber sleeve is fixedly sleeved on the bottom of the terminal, and a terminal plug hole and an insulating rubber sleeve plug hole are coaxially provided in the middle of the terminal base; a convex head is provided on the side wall of the terminal, a convex head clamping annular groove is provided on the side wall of the terminal plug hole, and a first notch for inserting or withdrawing the convex head is provided on one side of the terminal plug hole.

[0009] Furthermore, the protrusion is integrally connected to the terminal.

[0010] Furthermore, the side wall of the insulating rubber sleeve is provided with a boss, the side wall of the insulating rubber sleeve insertion hole is provided with a boss clamping annular groove, and the side wall of the insulating rubber sleeve insertion hole is provided with a second notch for inserting or withdrawing the boss.

[0011] Furthermore, bosses are symmetrically arranged on both sides of the insulating rubber sleeve.

[0012] Furthermore, the boss is integrally connected to the insulating rubber sleeve.

[0013] Furthermore, the bottom of the terminal is formed into a polygonal portion which matches and is fixedly sleeved with the insulating rubber sleeve.

[0021] The utility model will be described in detail below with reference to the accompanying drawings.

[0022] See also Figures 2 to 4 As shown, this embodiment discloses an anti-loosening welding machine wiring kit, including a terminal 3 and a terminal base 1, the bottom of the terminal is fixedly sleeved with an insulating rubber sleeve 2, and the middle of the terminal base is coaxially provided with a terminal plug hole 103 and an insulating rubber sleeve plug hole 101; preferably, the bottom of the terminal forms a polygonal portion 6 that matches and is fixedly sleeved with the insulating rubber sleeve, which is conducive to improving the reliability of fixing the insulating rubber sleeve to the terminal. The polygon can be a regular pentagon or a regular hexagon, etc.

[0023] The side wall of the terminal is integrally provided with a protrusion 4, the side wall of the terminal plug hole is provided with a protrusion clamping annular groove 104, and one side of the terminal plug hole is provided with a first notch 105 for inserting or withdrawing the protrusion.

[0025] When connecting, the terminal is coaxially inserted into the terminal base, wherein the terminal is matched with the terminal socket, and the insulating rubber sleeve is matched with the insulating rubber sleeve socket. During the insertion process, when the convex head slides along the first notch to the convex head clamping annular groove, the terminal is rotated so that the convex head is clamped into the convex head clamping annular groove (the convex head and the notch are avoided), so that the terminal can be axially fixed relative to the terminal base. When the convex head slides along the first notch to the convex head clamping annular groove, the boss also slides along the second notch 106 to the boss clamping annular groove and is clamped into the boss clamping annular groove.

[0026] In summary, the welding machine wiring kit of the present application improves the reliability of the connection between the terminal and the wiring base through the clamping of the protrusions and the annular grooves, and the clamping of the bosses and the bosses and the annular grooves, avoids poor contact and local overheating caused by the sinking or tilting of the terminal, improves the service life and reliability of the welding machine, can effectively reduce the wear of the column head and the column hole caused by the movement or involvement of the terminal during the use of the welding machine, reduces the replacement and repair frequency of the wiring base and the terminal, and saves repair costs. In short, the occurrence rate of equipment failures is reduced, the frequency of rework is reduced, the reliability of equipment is enhanced, and the work efficiency is improved.
