An electrode holder for arc welding, comprising a head, a pair of jaws within said head, a body connected with said head and adapted to be connected to the welding cable, and a handle surrounding said body and being removably fastened to the latter, wherein the fastening of the handle onto the body is formed by at least one pin which substantially radially extends from the body and engages into an opening of the handle, said pin being adapted to be depressed against spring action into a cut-out of the body.
An electrode holder for arc welding, comprising a head, a pair of jaws within said head, a body connected with said head and adapted to be connected to the welding cable, and a handle surrounding said body and being removably fastened to the latter, wherein the fastening of the handle onto the body is formed by at least one pin which substantially radially extends from the body and engages into an opening of the handle, said pin being adapted to be depressed against spring action into a cut-out of the body.
Description
S~3~
The present i.nvention relates to an electrode holder for arc welding, comprising a head, a pair of jaws within said head, a body connected with said head and adapted to be connected to the welding cable, and a handle surrounding said body and being removably fastened to the latterO
Such electrode holders are well-known in various embodimentsO
Usually the fastening of the substantially cylindrical handle (made of elec-trically insulating material) to the body (which is usually made of brass) is effected by means of two screws which are mounted in a countersunk fashion in a collar-like thickening of the handle at two diametrically opposite locations and are radially threaded into the bodyO It has been a drawback of this well- ~:
known fastening, that in use the fastening screws often get unlocked, which may be due to the body and the handle being subjected to expansion and subse- ~ .
quent shrinkage as a result of the substantial heat developmentO On the other hand the fastening needs to be readily releasable for the purpose of inspection of the connection between the body and the welding cableO
According to the present invention a safe and readily releasable fastening is obtained by making use of at least one pin which substantially radially extends from the body and engages into an opening of the handle, said pin being adapted to be depressed against spring action into a cut-out of the bodyO
, Thus the present invention makes use of a sort of snap connection, which is well-known in other fields of technicsO
In a practical embodiment the pin is accommodated in a radial ~
, bore of the body and provided with a collar which is movably housed in a widened portion of said bore, a spring being also housed in said widened por-tion and bearing onto said collarO
In a preferred embodiment the pin is made of electrically insulating material. In that case there is no objection to a contact between "' ``,:, - 1 - ~ ' :. ~ . . ' . : '' ,., ' ' " ~ ' ' "' :
,. . .
, ;' .
~4~S~l , the pin and the hand holding the handle, so that the outer end of the pin may extend so far as the outer surface of the handle and no protecting collar will be needed to avoid such contact.
The invention will be hereinafter further described by way of 0xample with reference to the accompanying drawingO
Z In the drawing the electrode holder is shown partially in side view and partially in longitudinal section. It comprises a head 1, which accommodates the clamping jaws (not shown) for holding a welding electrode to be introduced at Ao A sleeve 2 extends outwardly from a neck portion 3 of the head and is provided with external screw threadO The body 4~ adapted to be connected to the welding cable 5 is screwed onto the sleeve 20 A pressure pin 6 extends through the cylindrical sleeve 2 and has its head bearing onto the bottom of the bore of the body 4 accommodating said sleeve. The free end of the pressure pin 6 is adapted to act upon the movable clamping jaw (in a well-known manner and not shown in the drawing) of the pair of jaws accommodat-~¦ ed in the head 1. A substantially cylindrical handle is indicated at 70 It is locked both in tangential and axial direction relative to the body 4 and Z is yet readily releasably connected with said bodyO The connection is formed by a pin 8 having an enlargement or collar 9, mounted in a radial and (stepped) bore lOo The outer portion of the pin 8 extends through the narrow bore ' section outwardly and engages in a corresponding opening 11 of the handle 7, while the collar 9 and a spring 12 bearing on it are housed in the wider t portion of said bore~ The outwardly facing end of the wider portion of the -~ bore 10 is closed by a plug 130 The pin 8 and the handle 7 are made of electrically insulating materialO
It will be understood that the pin 8 may be pressed inwardly (by Z making use of a suitable piece of tool) against the action of the spring 12 ,Z to release the handle 7 from the body 4 in ord0r to have the opportunity to
