Description

8201793-0 2,;- är i detta fall utformat med fyra kontaktflikar 6, på vilka lämpli- ga ej visade kabelskor för anslutande kablar kunna trädas. 8201793-0 2,; - is in this case designed with four contact tabs 6, on which suitable cable shoes (not shown) for connecting cables can be threaded.

I .en i fig. 1 med streckade linjer antydd karosseriplât 1, i vil- ken ett kontaktbleck skall anbringas, åstadkommer man ett hål för blindnitens rör l, i vilket man skjuter in den med kontaktbleck för- sedda blindniten. Med ett dragverktyg, exempelvis en så kallad pop- nittång, drar man därefter dragsprinten 3 ett stycke uppåt, så att dragsprintens huvud delvis underifrån dras in i röret och stukar upp rörets nedre under plåten belägna del. I lämpligt läge på dragsprinter finns en försvagning, som underlättar, att man efter färdig nitning kan bryta av den överskjutande delen Ba av dragsprinten, antydd me- delst streckade linjer.In a body plate 1 indicated by dashed lines in Fig. 1, in which a contact plate is to be fitted, a hole is provided for the tube 1 of the blind rivet, into which the blind rivet provided with contact plates is inserted. With a pulling tool, for example a so-called pop rivet pliers, the pulling pin 3 is then pulled a bit upwards, so that the head of the pulling pin is partly pulled into the tube from below and upsets the lower part of the tube located under the plate. In a suitable position on the traction printer, there is a weakening, which facilitates that, after complete riveting, the excess part Ba of the traction sprint can be broken, indicated by dashed lines.

Den med streckade linjer antydda utvidgade delen la av blindnitensg rör pressas mot kanten av hålet i karosseriplåten och ger god elekt- risk kontakt, förbättrad genom den uppruggning av blindnitens yta som de ovan angivna gängorna 2 och så vidare ger utan att man behö- ver Slipa bort eventuell elektriskt isolerande beläggning på plåten.The extended part 1a of blind rivet pipe indicated by dashed lines 1a is pressed against the edge of the hole in the body plate and provides good electrical contact, improved by the roughening of the surface of the blind rivet which the above-mentioned threads 2 and so on provide without having to grind. remove any electrically insulating coating on the sheet.

Detta innebär en arbetsbesparing. Det går ju fortare att blindnita än att skruva fast kontaktblecket och erforderliga antalet detaljer reduceras. Bland annat slipper man ifrån att behöva plocka med skru- var och dylikt. ' I fig. 3 - 5 visas ett utförande av kontaktblecket med nedhängande flikar 8, vilka vid nitningen skära igenom lackskiktet på karosseri- plåten och åstadkomma elektrisk kontakt. Dessa flikar kunna även _fungera som avståndsstycken, som håller kontaktblecket på något av- stånd-från plåten, vilket kan vara önskvärt i det fall att försvag- ningen på dragsprinten har placerats så högt, att den efter nitningen g skulle komma ovanför kontaktblecket och efter dragsprintens avbrytan- de skulle kvarlämna ett ovanför kontaktblecket uppskjutande ej önsk- värt stift. AThis means a labor saving. It is faster to blind blind than to screw on the contact plate and the required number of details is reduced. Among other things, you avoid having to pick with screws and the like. Figs. 3-5 show an embodiment of the contact plate with hanging tabs 8, which during riveting cut through the lacquer layer on the body plate and make electrical contact. These tabs can also function as spacers which keep the contact plate at some distance from the plate, which may be desirable in the case that the weakening of the tension pin has been placed so high that after riveting g it would come above the contact plate and after the tension pin. interrupting would leave an undesirable pin projecting above the contact plate.

Claims

f, 8201793-0 Patentkray.

1. Phase riveting in a frame-shaped boom intended for a needle in a plate (7): - rivet (1), characterized by a connector (5) attached to the blind rivet accessible after riveting, which is electrically connectable to the plate (7) by widening and pressing the blind rivet against the edge of the rivet hole in the plate at the rivet rivet of the blind rivet. in

2. A blind rivet according to claim 1, characterized in that the connector consists of a contact plate (5) known per se.

Blind rivet according to Claim 1 or 2, characterized in that the blind rivet consists of a tube (1) known per se, in which a similarly known tension pin (3) provided with head (A) is inserted for expansion. of the "blind" end of the blind rivet by pulling on the tension pin. '' '

Blind rivet according to one of Claims 1 to 3, characterized in that the surface of the blind rivet (1) is threaded; ribbed, lettered or otherwise roughened on at least the part of the tube of the blind rivet (1) which, when riveted, widens towards the edge of the hole in the plate (7).

Blind rivet according to one of Claims 2 to 1, made of nets drawn from the underside of the contact plate (5) (8) for penetrating an insulating layer present on the plate (7) or for function as spacers between the contact plates (5). ) and the plate (7).
