Abstract

The utility model relates to a pair of electric soldering pliers used for manual arc welding operation, comprising an upper jaw, a lower jaw, an upper plier cover, a lower plier cover, a bending handle, a clamp pin, a handle, a spring and a spring seat. The utility model is characterized in that the lower jaw is composed of a plier head which is tightly fixed in a bracket and the bracket, the lug at the upper end of the bracket is movably connected with the upper jaw by the clamp pin, the lower end of the bracket is bent into a hollow chamber in which a copper sleeve is arranged, the copper sleeve is fixedly connected with a cable by screws, and the plier head and the bracket are respectively tightly fixed with the lower plier cover and the handle by the screws. The cable wiring position of the electric soldering pliers is moved to the lower jaw from the handle, therefore, the length of a conductive body is shortened, and the temperature rise of a handle surface is reduced. The cable connection adopts the mode of external connection, therefore, the wiring can be carried out without disassembling the handle, and the use is convenient. The bracket is formed by stamping steel sheets and is plated with copper, therefore, copper consumption is reduced, and production cost is saved.

Description

Grip type electrode holder

The utility model relates to a kind of soldering appliance, is used for the electrode holders of manual arc welding operation.

In manual arc welding operation, electrode holders are used for clamping welding rod and bearing great current, make between welding rod and the welding base metal and produce electric arc, and fusing welding rod and mother metal weld.Existing clipping electrode holders by upper jaw, lower jaw, go up the pincers cover, pincers cover, curved handle, clamp pin, handle, spring and spring base are formed down, upper and lower jaw connects rotatable with clamp pin, upper jaw is connected with curved handle, the pincers cover is equipped with in the outer end, and lower jaw is connected with handle, and the pincers cover is equipped with down in the outer end, between curved handle and the handle spring is housed, spring is positioned at the spring base that is installed on the handle, and the tail end of lower jaw is provided with the wiring hole, is used for fixing stube cable.In welding process, between welding cable in the electrode holders handle and the lower jaw wiring hole under the effect of heavy current, the heat that will have a resistance, the time has been grown, the handle surfaces temperature raises, and influences welding operation so that scald one's hand.

The purpose of this utility model provides a kind of rational in infrastructure, the clipping electrode holders that the handle surfaces temperature rise is low.

The structure of the electrode holders that the utility model proposes comprises upper jaw, lower jaw, goes up the pincers cover, clamps cover, curved handle, clamp pin, handle, spring and spring base down, upper and lower jaw connects rotatable with clamp pin, the outside of upper jaw is equipped with the pincers cover and is connected with curved handle, the outside of lower jaw is equipped with down the pincers cover and is connected with handle, between curved handle and the handle spring is housed, spring is positioned at the spring base that is installed on the handle.It is characterized in that lower jaw is made up of binding clip and support, binding clip is anchored in the support, and support upper end lug is with clamp pin and upper jaw flexible connection, the support lower end curves cavity, in establish copper sheathing, be screwed stube cable, binding clip and support respectively with screw with down pincers cover and handle are fastening.

Electrode holders move to lower jaw with the cable connection position from handle through above-mentioned improvement, have shortened electric conductor length, have reduced the temperature rise of handle surfaces, confirm that after tested the temperature rise of these electrode holders handle surfaces is below 25 ℃.In addition, lower jaw is divided into binding clip and support, support can be made copper facing again with the steel plate punching press, thereby has reduced copper consumption, has saved production cost, has alleviated overall weight simultaneously.At last, change the cable connected mode into circumscribed, easy to use.Originally the mode of connection of product is an internal connecting type, needs the wiring again of demolition handle, troublesome poeration.

Followingly with reference to accompanying drawing concrete enforcement of the present utility model being further described, is the structure chart of clipping electrode holders shown in the accompanying drawing.Its structure comprises upper jaw (2), lower jaw, upward pincers covers (1), following pincers cover (8), curved handle (4), clamp pin (3), handle (7), spring (5) and spring base (6).Upper jaw (2) is connected rotatable with lower jaw with clamp pin (3), the outside of upper jaw (2) is equipped with pincers covers (1) and is connected with curved handle (4), the outside of lower jaw is equipped with down pincers covers (8) and is connected with handle (7), between curved handle (4) and the handle (7) spring (5) is housed, spring (5) places in the spring base (6) that is installed on the handle (7).It is characterized in that lower jaw is made up of binding clip (10) and support (13), binding clip (10) is made of copper and is anchored in the support (13), support (13) upper end lug flexibly connects with clamp pin (3) and upper jaw (2), support (13) lower end curves cavity, in establish copper sheathing (11), be fastenedly connected cable with screw (12), copper facing is again made in the available steel plate punching press of support (13), and binding clip (10) uses screw (9), (14) respectively with support (13) and pincers covers (8) and handle (7) are fastening down.
