Description

Technical Field

[0001] The utility model belongs to the technical field of electric connector lead welding, and in particular relates to an auxiliary tool for welding high-current connector leads. Background Art

[0002] The existing high current field electrical connector leads are mostly 8 to 16 mm 2 High temperature wire, and each has multi-phase windings.

[0003] The common welding method for high-current connectors is for operators to directly weld, then fix the electrical connector to the drive chassis, and finally use a torque screwdriver to tighten the cold-pressed terminal.

[0004] This welding method is simple and direct, but there are the following problems in practice: ①16mm 2 1. The wire diameter is too thick to be fixed, and the operation is inconvenient, so that the solder does not wet the metallized hole 100%, which is easy to cause cold solder joints and affect the welding quality; in severe cases, the insulation layer of the wire will be damaged, resulting in the wire core being exposed or excess material being produced; 2. During direct welding, the electrical connector seat swings arbitrarily, resulting in the final wire length being inconsistent with the design requirements, and the wire welding is distorted, which leads to the failure to install the electrical connector tail clip, and affects the mismatch between the cold-pressed terminal and the mounting hole diameter on the chassis, resulting in repeated welding, which is time-consuming and labor-intensive; 3. During direct welding, it is generally difficult for one operator to complete the two actions of fixing the electrical connector and welding the wire at the same time, and it is even more difficult to ensure the welding quality. Generally, two or more operators are required to complete it, which prolongs the working time and reduces work efficiency. Utility Model Content

[0005] The utility model aims to provide a high-current connector lead welding auxiliary tooling to overcome the problems of poor welding quality and low efficiency caused by the lack of corresponding auxiliary tooling in the existing electrical connector lead welding.

[0009] Furthermore, the support frame and the insulating plate are fixed with cross-slot pan head screws.

[0010] Furthermore, the support frame is an angle support frame.

[0011] Furthermore, each of the electrical connector mounting slots corresponds to two lead fixing holes.

[0012] Furthermore, the electrical connector mounting slot has the same outer dimensions as the high current connector.

[0013] Furthermore, the distance between the electrical connector mounting groove and the corresponding lead fixing hole is the same as the length of the high current connector lead.

[0014] Furthermore, five electrical connector installation grooves are provided on the surface of the insulating board.

[0015] Compared with the prior art, the utility model has the following beneficial technical effects:

[0016] The utility model provides a high-current connector lead welding auxiliary tool, comprising an insulating plate, a support frame installed on one side of the insulating plate, an acute angle between the support frame and the insulating plate, an electric connector installation groove and a lead fixing hole are opened on the other side of the insulating plate, which are used for fixing the electric connector and the lead to be welded.

[0024] Glossary:

[0025] A high current connector is a connector that can carry high currents and is usually used in power supplies, motor control, automotive, and other fields. The main feature of a high current connector is that it can carry large currents, usually between tens of amperes and hundreds of amperes. The following are several main features of high current connectors:

When the lead of the electric connector is welded, the high-current connector is fixed in the electric connector mounting groove 3 on the insulating plate 2, and one end of the lead is fixed through the lead fixing hole 4 corresponding to the electric connector mounting groove 3, wherein the length between the electric connector mounting groove 3 and the lead fixing hole 4 is the same as the length of the lead to be welded, thereby achieving the fixation of the lead and the electric connector, and solving the problem of cold welding and welding bending caused by the random swing of the lead and the electric connector during welding.

[0033] A high current connector lead welding auxiliary tooling includes an insulating plate 2 and a support frame 1. The insulating plate 2 is fixed by the support frame 1.

[0034] The lead fixing hole 4 is a screw hole, through which a cross-slot countersunk screw is inserted from the back of the insulating plate and fixed with a nut on the front, so as to fix the cold-pressed terminal at one end of the lead.

[0037] The other side of the insulating plate 2 is connected to the support frame 1, wherein the support frame 1 adopts an angle support frame, wherein there are two angle support frames, which are respectively fixed on both sides of the insulating plate 2 and fixed with four cross-slot pan head screws to play a supporting role.

The other side of the insulating plate 2 is connected to the support frame 1, wherein the support frame 1 adopts an angled support frame.

[0040] Among them, there is one angle support frame, which is ensured to have sufficient width, fixed in the middle of one side of the insulating plate 2, and fixed with two cross-slot pan head screws, so as to play a supporting role.

[0041] Example 4

[0042] A high-current connector lead welding auxiliary tool comprises an insulating plate 2 and a support frame 1. The angle between the support frame 1 and the insulating plate 2 is 45 degrees.
