Abstract
The utility model relates to the field of metal welding tools, and in particular relates to an electrode holder. The safety electrode holder mainly comprises a main body, an upper handle and a shell, wherein the main body is arranged in the shell, a spring is arranged between the shell and the upper handle and plays an automatic pressing role, and the shell is connected with the upper handle through a connecting shaft; and the safety electrode holder is characterized in that the length of the main body is 1/4 to 2/5 of that of the shell. Compared with the prior art, the electrode holder has the advantages that rated conducting current of the sectional area of the main body is higher than the maximum current passing through during operation, so that the main body does not generate heat; a base plate is additionally arranged at the joint between the main body and a conductor, and the contact area is enlarged, so that heat transfer from the conductor to the main body becomes secondary heat transfer, and the temperature of the main body is indirectly reduced; and 3, the position of the main body is changed and is staggered from the hand holding part, so that the heat generated by the electrode holder during operation cannot be conducted to the hand holding part, hands of an operator are not scalded, and therefore the electrode holder can continuously work for a long time.
Description
Technical field
The utility model relates to the metal solder field of tool, relates to a kind of electrode holders specifically.
Background technology
Electrode holders use extensively in industries such as industry, building, shipbuilding, maintenance at present.Ubiquitous problem is: these electrode holders long working will cause operating personnel's hand to have scalding one's hand sense, make inefficiency.Be connected that also can play electric action partly is main body up to jaw in the electrode holders with lead; For the weight that makes whole electrode holders is fit to hand-held; Usually principal length is equivalent to be attached thereto the length of handle together, that is to say that it is the half the of outer cover length that main body accounts for whole electrode holders length.Because therefore the local high temperature that has about 1000 degree of the welding rod of electrode holders clamping fusing, be delivered to handle outer end nearby through the main body that is easy to heat conduction very soon during operation, operating personnel on hand.In addition, the spring that the electrode holders handle is provided with directly links to each other with main body, therefore has the low tension that main body passes over; Though be low tension, covered major part by shell again, can not injure the operator; But, during operation because of pause, shift position or when placing on the workpiece at work, be prone to workbench on objects such as uneven integral point or metal impurities produce to draw and bump; And then the generation electric spark, have certain potential safety hazard.
The utility model content
The utility model is intended to overcome the prior art defective, and a kind of safety electric welding tongs is provided.
Safety electric welding tongs mainly is made up of main body, upper handle and shell, and described main body places in the shell, is provided with spring between described shell and the upper handle, plays automatic pressuring action; Described shell links to each other through connecting axle with upper handle, it is characterized in that: described principal length is 1/4～2/5 of an outer cover length.
Compared with prior art, the advantage of the utility model is:
The maximum current that is passed through when 1, the specified conductive current of main body section area is greater than work, and then guarantee that main body itself does not produce heat.
2, install backing plate additional in main body and conductor junction, increased contact area and made the heat transfer from the lead to the main body become the secondary heat transfer, reduce body temperature indirectly.
3, change body position and make it away from holding the place, promptly principal length is merely 1/4～2/5 of outer cover length, and the heat conduction that produces when making electrode holders work is less than holding the place, and operator's non-scald on hand gets final product long time continuous working.
4, the convexity that adds on the main body cover guarantees that screw head can not expose main body cover, avoids bumping the phenomenon that produces electric spark with extraneous drawing, and the louvre that on main body cover, is provided with in addition, the heat that produces during to body of work has certain heat sinking function.
