Detailed Description
The present invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1 to 5, a welding auxiliary tool for assisting welding between a circuit board 101 and a wire harness 102 is described, which includes an upper cover plate 1 and a lower carrier plate 2, the upper cover plate 1 and the lower carrier plate 2 being mounted together by hinges 3 (two shown) so that the upper cover plate 1 can be opened and closed with respect to the lower carrier plate 2. Of course, the upper cover plate 1 and the lower cover plate 2 can be connected together in other openable and closable manners. The upper and lower decks 1, 2 are typically made of a high temperature resistant material to avoid damage during welding. The upper cover plate 1 is provided with a welding window 11, the welding window 11 corresponds to a position (shown in fig. 3) to be welded of the circuit board 101 and the wire harness 102, and the shape and the size of the welding window 11 can be set according to actual needs. The upper surface of the lower carrier plate 2 is provided with a circuit board positioning slot 21 and a wire harness positioning slot 22 which are substantially consistent with the outline of the circuit board 101 and the wire harness 102, and the circuit board 101 and the wire harness 102 can be positioned and placed in the circuit board positioning slot 21 and the wire harness positioning slot 22. The depth of the board positioning groove 21 and the harness positioning groove 22 is substantially equal to the thickness of the board 101, and they can be manufactured in a usual processing manner.
In the embodiment shown, for facilitating the taking and placing of the circuit board 101, the two sides of the circuit board positioning slot 21 are provided with relief notches 23. The relief notch 23 is provided to enable a finger of an operator to be positioned so that the finger can enter therein. Preferably, the relief notch 23 is a circular hole.
Preferably, in order to enable the upper cover plate 1 and the lower cover plate 2 to cover together to clamp the circuit board 101 and the wiring harness immovably, a magnetic attraction device is further provided between the upper cover plate 1 and the lower cover plate 2. Specifically, in the illustrated embodiment, the magnetic attraction means are two pairs of magnetic columns 4 disposed on the upper cover plate 1 and the lower cover plate 2. It should be understood that the number of the magnetic columns 4 is not limited to the illustrated embodiment, and may be one pair or three pairs and more. The shape of the magnetic cylinder 4 may be circular or square, etc. Each pair of magnetic poles 4 may be a pair of magnets with opposite poles, or one of them may be a magnet and the other a ferromagnetic material.
