DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

FIG. 1 and FIG. 2, show an embodiment of an electrical soldering iron head 100 including a heat-conducting pipe 20, a connecting member 40, a first heating block 60, a second heating block 80, and an operation member 90.

The heat-conducting pipe 20 can be connected to a heat pole of an ordinary electric soldering iron (not shown).

The connecting member 40 includes a rectangular fixing block 42 fixed to an end of the heat-conducting pipe 20, and an installation block 44.

The fixing block 42 includes a top surface 421 fixed to the heat-conducting pipe 20, a bottom surface 422 defining a rectangular receiving space 424, and two opposite side surfaces 423. The receiving space 424 extends along a lengthwise direction of the fixing block 42. The fixing block 42 defines a through hole 425 extending through the side surfaces 423, and four screw holes 426 in four corners of the bottom surface 422. The through hole 425 communicates with the receiving space 424.

The installation block 44 includes a top surface 441, a bottom surface 442 opposite to the top surface 441, and two opposite end surfaces 443. The installation block 44 defines a guiding slot 444 extending along a lengthwise direction of the installation block 44, a cutout 445 extending through one of the end surfaces 443 adjacent to the guiding slot 444, and four fastening holes 446 in four corners of the top surface 441. The guiding slot 444 communicates with the guiding slot 444.

The first heating block 60 includes a first extending pole 62 perpendicularly extending down from the installation block 44 opposite to the cutout 445, and a first clamping portion 64 slantingly extending from a distal end of the extending pole 62 toward the guiding slot 444.

The second heating block 80 includes a sliding piece 82, a gear rack 83 fixed on a top of the sliding piece 82. A second extending pole 84 perpendicularly extends down from a first end of the sliding piece 82 opposite to the gear rack 83, a second clamping portion 86 slantingly extending down from a distal end of the extending pole 84 toward a second end of the sliding piece 82. In addition, a pin 88 extends out from a lateral side of the extending pole 84 opposite to the second end of the sliding piece 82. The extending pin 88 is marked with a length scale.

The operation member 90 includes a gear 92 and a screw 94. A circular operation portion 924 extends out from a first end of the gear 92. A diameter of the operation portion 924 is greater than a diameter of the through hole 425. A second end of the gear 92 opposite to the operation portion 924 axially defines a screw hole 922.

Referring to FIG. 3 and FIG. 4, in assembly, the gear 92 is rotatably inserted into the through hole 425. The second clamping portion 86 extends through the guiding slot 444 from the top surface 441, with the second extending pole 84 slidably received in the guiding slot 444. The sliding piece 82 is slidably blocked by the top surface 441. The pin 88 is slidably received in the cutout 445. The bottom surface 422 is supported on the top surface 441. The sliding piece 82 is slidably received in the receiving space 424. The gear rack 83 meshes with the gear 92. Four screws extend though the fastening holes 446, to be screwed into the corresponding screw holes 426. The screw 94 is inserted into the through hole 425 to screw into the screw hole 922, for preventing the gear 92 from being disengaged from the through hole 425. Therefore, the gear 92 is rotatably received in the through hole 425, the gear 92 is rotated to drive the gear rack 83 to slide. The second clamping portion 86 slides toward or away from the first clamping portion 64 along the guiding slot 444. The scale of the pin 88 aligns with the end surface 443 to show a distance between distal ends of the first and second clamping portions 64 and 86. In use, the distance is equal to a distance between two opposite pins of an electronic component clamped by the first and second clamping portions 64 and 86.

FIG. 5 and FIG. 6, show the operation portion 924 being operated to rotate the gear 92 to drive the gear rack 82. Allowing the second heating block 80 to slide relative to the first clamping portion 60, until the distal ends of the first and second clamping portions 64 and 86 can clamp the pins of the electronic component. The heat-conducting pipe 20 is connected to a heating pole of an ordinary electric soldering iron (not shown). The heating pole generates a quantity of heat, the heat is guided to the first and second clamping portions 64 and 86, to solder the pins of the electronic component to the corresponding pads of a printed circuit board (not show).

Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
