Abstract

The utility model provides a soldering iron head for a multi-pin element, the head 1 is a plate strip block whose section is an upper arched arc, and the head and an end 4 are bending connected as integration into an L-shaped. The utility model can simultaneously solder each feet of multi-feet elements such as an integrated circuit, so the utility model can increase the work efficiency, shorten the soldering time and reduce the damage to a copper foil and an element of a printed circuit board. The utility model can be made into serial products with different dimensions according to the types of the soldering dismount elements, which is an ideal tool for soldering multi-feet elements in electric apparatus repairing.

Description

Soldering iron head for multi-pin element

The utility model relates to a kind of multiway element disassembled welding electric soldering iron head of soldering appliance.

At maintenance electrical equipment, when welding multiway elements such as tearing integrated circuit block open, all be to weld respectively by pin to tear open now.For absorbing the scolding tin on the solder joint, the electric soldering bit device of scolding tin has appearred in the prior art absorbing, " a kind of electric soldering bit device that suction tin function is arranged " (86202461), " the special-purpose serial electric soldering bit of integrated circuit " (86210320), " inhale soldering and connect dual-purpose solder horn " (87208866) as the Chinese patent bulletin, still must butt welding tearing element open because of them pursues the pin weldering and tears open, efficient is low, time-consuming, often tears long copper pool and the element that damages printed circuit board (PCB) of time open because of weldering.

The purpose of this utility model is to overcome above-mentioned weak point and provides a kind of easy to use, and each pin of multiway element is welded the multiway element disassembled welding electric soldering iron head of tearing open simultaneously.

Multiway element disassembled welding electric soldering iron head is L-shaped, and head is the lath block that curved arch is presented in the cross section; Afterbody is a cylinder, and tail end vertically is drilled with circular hole and has vertical sulculus (internal heat type) in both sides, afterbody or be cylinder (external-heat).

Fig. 1 (a) and (b), (c) are respectively the utility model front view, vertical view and left view.

Fig. 2 is the A-A cutaway view.

Head 1 is presented the lath block of curved arch for the cross section, and two long side faces are that inclined-plane 2, base are plane 3; Afterbody 4 is a cylinder, and tail end vertically is drilled with circular hole 5 and has vertical sulculus 6 in both sides.Head 1 and afterbody 4 arcs fuse L-shaped.According to the type that element is torn in weldering open, can be made into the series of products of different size.

The utility model is owing to adopt above design, heat energy by the generation of thermal source Electric soldering iron core, conduct to each position, head 1 front and back simultaneously through head 1 and afterbody 4 coupling parts, head 1 rear end quality is big, temperature rises slow, though and head 1 front end is big from the thermal source distance, quality is little, so head 1 each position is heated even substantially, mechanical strength is big, easy to use, can weld simultaneously each pin of multiway elements such as integrated circuit block and tear open, improved operating efficiency, having shortened weldering tears open the time, reduced damage to printed circuit board (PCB) copper pool and element, through on probation, respond well.

Claims

1, a kind of multiway element disassembled welding electric soldering iron head, its afterbody (4) are cylinder, and tail end vertically is drilled with circular hole (5) and has vertical sulculus (6) (internal heat type) in both sides; Afterbody (4) or be cylinder (external-heat) is characterized in that head (1) presents the lath block of curved arch for the cross section.

2, multiway element disassembled welding electric soldering iron head as claimed in claim 1, the two long side faces that it is characterized in that head (1) are that inclined-plane (2), base are plane (3).
