Abstract

Disclosed are electrode holders. A wiring device is arranged on the outer surface of a casing (9), and the copper piece on the front end of the wiring device is glued on an electric conductor (11) in the casing. The electric conductor is provided with a groove (10) penetrating through the electric conductor, and the electric conductor is pressed to be positioned by a pressing block (12). A clamping piece (8)which is provided with teeth on one end surface and the electric conductor are adjacent, and the clamping piece (8) is clamped to be positioned by a pressing screw rod (4), a spring (6) and a heat insulation pad (7). The input electric cable of the electrode holders is not arranged in handles which do not burn hands, and a bite welding rod is of strong holding power and is of stable current. The electrode holders is of simple preparing process, is of low cost and is of low metallic electric conductor consumption.

Description

A kind of electrode holders

Technical field

The utility model belongs to the welding tool field.

Background technology

Existing electrode holders, cable by being connected with conductive copper bar in the electrode holders, because heating is too many, make handle hot in the middle of the handle, and operation is very inconvenient, also dangerous.And not only slightly but also long, it was many to consume copper material for conductive copper bar.In addition, electrode holders clamping welding rod is mainly by a tension spring, but this spring very easily produces not enough power or the uneven problem of power, causes welding rod to come off easily or loose contact.

Summary of the invention

The technical problems to be solved in the utility model provides the electrode holders that a kind of handle does not generate heat, electrode carrier gets surely, amount of copper consuming is few again.

The utility model solves the problems of the technologies described above with following technical scheme: termination is contained in the outer surface of sheath body 9, and its front end copper sheet is fitted with electric conductor 11 in sheath body, and the groove 9 of break-through electric conductor is arranged on the electric conductor, and electric conductor compresses the location by compact heap 12; Adjacent with electric conductor is the intermediate plate 8 that tooth is arranged on the end face, and intermediate plate is by clamping screw 4, spring 6 and heat insulating mattress 7 clamping and positioning.Screw rod 2 passes the central straight of clamping screw 4, spring 6 and heat insulating mattress 7 and supports sheath body 9.

Electrode holders input cable of the present utility model is not gone in the handle, and handle non-scald on hand, tooth are stung electrode carrier and held power, conductor contact well, and the soldering turret manufacture craft is simple, and cost is low, and metallic conductor consumption copper is few, has market prospects.

Description of drawings

Fig. 1 is the structural representation of the utility model electrode holders.

The specific embodiment

Termination 16 is contained in the outer surface of sheath body 9, and its front end copper sheet is fitted with electric conductor 11 in sheath body, and the groove 10 of break-through electric conductor is arranged on the electric conductor, and electric conductor compresses the location by compact heap 12; Adjacent with electric conductor is the intermediate plate 8 that tooth is arranged on the end face, and intermediate plate is by clamping screw 4, spring 6 and heat insulating mattress 7 clamping and positioning.Screw rod 2 passes the central straight of clamping screw 4, spring 6 and heat insulating mattress 7 and supports sheath body 9.

When using electrode holders to weld, earlier cable 17 is inserted terminations 16, welding rod passes the through hole 15 of sheath body 9 and firmly in the groove 10 through electric conductor, the tooth on groove and the intermediate plate 8 is clamped welding rod from the both sides of welding rod respectively.Because there is brute spring 6 at the intermediate plate rear, welding rod can be held very tight.The guide card of energising back termination 16 front ends is about to electric current and inputs on the electric conductor 11 of fitting with guide card, welding rod get final product electric work.

By adjusting nut 3, can regulate the axial location of clamping screw 4, thereby make the pressure of spring adjusted.Hold-down screw 5 is in order to connect handle 1 and clamping screw 4.Screw 13 is in order to the position of fixed insulation cover 14.This electrode holders cable is not gone in the handle, and handle non-scald on hand, tooth are stung electrode carrier and held power, current stabilization, and the soldering turret manufacture craft is simple, and cost is low, and the metallic conductor consumption is few, has market prospects.

Claims (2)

1. electrode holders, electric conductor, welding rod holing clip and handle are arranged, it is characterized in that termination is contained in the outer surface of sheath body (9), its front end copper sheet is fitted with electric conductor (11) in sheath body, the groove (10) of break-through electric conductor is arranged on the electric conductor, and electric conductor compresses the location by compact heap (12); Adjacent with electric conductor is the intermediate plate (8) that tooth is arranged on the end face, and intermediate plate is by clamping screw (4), spring (6) and heat insulating mattress (7) clamping and positioning.

2. electrode holders as claimed in claim 1 is characterized in that the screw rod (2) in the handle passes the central straight of clamping screw (4), spring (6) and heat insulating mattress (7) to sheath body (9).
