Description

Melt welding jig

Technical Field

The utility model relates to a fuse trade, especially in the fuse production process, fuse-element and binding post welded welding jig.

Background

In the fuse production process, the fuse-element has multiple form with binding post's the mode of arranging, and a fuse-element welds with binding post, and two parallel intervals of fuse-element weld with binding post, and the fuse-element both ends weld the mode of arranging such as tip, the side at binding post link. Aiming at different arrangement modes, the adopted spot welding modes are different. Because this series of fuse exists multiple fuse-element mode of arranging at present, lead to the spot welding degree of difficulty to increase, cause unfavorable phenomena such as fuse-element deformation easily when the spot welding.

Disclosure of Invention

The utility model aims at providing a fuse-element welding tool can very conveniently spot weld the fuse-element on binding post, can not cause the fuse-element to deform, applicable spot welding in multiple fuse-element mode of arranging.

In order to realize the technical purpose, the utility model provides a technical scheme is a melt welding jig, including the bottom plate the interval is provided with two conducting blocks of relative position adjustable relatively on the bottom plate, set up the first recess that can place binding post who link up its both ends above the conducting block.

Furthermore, the end surfaces of the two adjacent ends of the two conductive blocks are respectively provided with a second groove which is deep and runs through the two sides of the conductive block.

Furthermore, two parallel through hole grooves are arranged on the bottom plate at intervals, and one conductive block is detachably fixed in the through hole groove on the bottom plate.

Furthermore, a fixing column is arranged at the bottom of the conductive block at a position corresponding to the through hole groove, and the fixing column penetrates through the through hole groove and then is fixed on the bottom plate through a locking nut.

The melt welding jig of the utility model facilitates the melt welding and can ensure that the melt is not deformed in the welding process; and the positions of the two conductive blocks can be adjusted, and the welding requirements of different melt lengths can be used. The welding jig is simple in structure and easy and convenient to operate, and improves welding efficiency while improving melt welding quality.

Detailed Description

With respect to the above technical solutions, preferred embodiments are described in detail with reference to the drawings.

The melt welding jig, see fig. 1 and 3, includes a bottom plate 1, a conductive block 2 and a conductive block 3. The bottom plate 1 is of a long-strip flat plate structure, two long-strip through hole grooves 11 are arranged at one end of the bottom plate in parallel at intervals, and the length directions of the through hole grooves are consistent with the length direction of the bottom plate. Two fixing through holes 12 are spaced apart from each other at the other end of the base plate.

The

conductive blocks

2 and 3 are made of red copper. Two fixing posts are respectively arranged on the bottoms of the

conductive blocks

2 and 3 at intervals, and the fixing posts 21 of the conductive blocks 2 are inserted into the through hole grooves 11 of the base plate and fixed on the base plate through locking nuts (not shown). When the conducting block needs to be moved, the locking nut is loosened, the conducting block is moved to a proper position along the through hole groove, and then the locking nut is screwed down to fix the conducting block. The fixing column of the conductive block 3 is arranged on the through hole 12 of the bottom plate in a penetrating way and fixed through a locking nut.

First grooves (22, 32) penetrating through two ends of the conductive block 2 and the conductive block 3 are respectively formed in the upper surfaces of the conductive blocks, and the shape of the first grooves (22, 32) meets the requirement that a fuse wiring terminal is placed on the first grooves. The central axes of the first grooves (22, 32) on the conductive block 2 and the conductive block 3 coincide. And deep second grooves (23, 33) are respectively formed on the conductive blocks close to the opposite two ends of the conductive block 2 and the conductive block 3, and the second grooves penetrate through the two sides of the conductive blocks.

The terminal, see fig. 4, includes a terminal portion 41 and a fixing plate 42. During welding, the distance between the two conductive blocks is adjusted according to the length of the melt A to be welded. The two wiring terminals are respectively placed on the two conductive blocks, the wiring terminal part is placed in the first groove, the fixing plate is placed in the second groove, then the two ends of the melt A to be welded are placed at the positions, needing to be welded, of the two wiring terminals, and spot welding is conducted through spot welding equipment. Because in welding process, binding post passes through the conducting block to be fixed, therefore its position keeps unchangeable, and supports the fuse-element, the condition that the fuse-element deformation appears in the welding process can not appear.
