Abstract

The device is for taking apart an electrical coupling unit (10, 11) of the pin plug type, and comprises a pincers-type tool with two arms (1) which are rotatably connected around a point (2), whereby the one ends of the arms have grip jaws (3) for gripping the coupling unit and the arm other ends form a hand grip for separating the coupling unit with the aid of lever effect. The grip jaws support a braking component (5) which is pushed into a joint in the coupling unit when the hand grip is pushed together for taking apart the coupling unit. At least one of the breaking components is fixed on a link arm (6) on the one of the grip jaws, the link arm being rotatably located around a point (7) on the grip jaws. The link arm has the form of a U-shaped stirrup, each arm of the stirrup supporting a braking component on its inside.

Description

<.... 10 15 20 25 30 508 706 2 fjäder 4. Gripkäftarna 3 uppbär brytorgan 5 som är avsedda att föras in i en skarv i kopplingsdonet för att ta isär detta. <.... 10 15 20 25 30 508 706 2 spring 4. The gripping jaws 3 support breaking means 5 which are intended to be inserted into a joint in the connector to disassemble it.

Den i fig. 1 och fig. 1A samt fig. 2 - fig. 2C visade anordningen har två bygelformade länkarmar 6 som är vridbart lagrade runt punkterna 7 på gripkäftarna. Fig. 1A är en för- storad sektionsvy enligt A-A i fig. 1 och fig. 2A är en sek- tionsvy enligt D-D i fig. 2, varjämte fig. 2B är en förstorad sektionsvy enligt B-B i fig. 2 och fig. 2C är en vy enligt C-C i fig. 2B. Det framgår av fig. 2B att brytorganen 5 är utförda med ett urtag 8 som följer kopplingsdonets profil. Av fig. 2c framgår att brytorganen 5 är utförda med en avfasning 9 för att passa in i en skarv i kopplingsdonet. Brytorganen 5 är fästa på länkarmarna 6 som har formen av en U-formad bygel, varvid vardera skänkeln hos bygeln uppbär var sitt brytorgan 5 på skänkelns insida.The device shown in Fig. 1 and Fig. 1A and Fig. 2 - Fig. 2C has two stirrup-shaped link arms 6 which are rotatably mounted around the points 7 on the gripping jaws. Fig. 1A is an enlarged sectional view according to AA in Fig. 1 and Fig. 2A is a sectional view according to DD in Fig. 2, and Fig. 2B is an enlarged sectional view according to BB in Fig. 2 and Fig. 2C is a view according to CC in Fig. 2B. It can be seen from Fig. 2B that the switch means 5 are made with a recess 8 which follows the profile of the connector. From Fig. 2c it can be seen that the switch means 5 are made with a chamfer 9 to fit into a joint in the connector. The breaking members 5 are attached to the link arms 6 which have the shape of a U-shaped stirrup, each leg of the stirrup each supporting its breaking member 5 on the inside of the leg.

I fig. 1 och fig. 1A visas utföringsformen i sitt viloläge, dvs. det läge där käftarna 3 är hopförda tack vare verkan från fjädern 4. Det kopplingsdon som skall tagas isär är antytt med streckade linjer i de olika ritningsfigurerna och donet utgöres av en hondel 10 och en handel 11. I fig. 1, 3 och 5 är antytt hur brytorganen 5 föres in i det spår 12 som I fig. 2 4 visas det läge där skarvdonet är isärtaget genom bildas i skarven mellan hondelen 10 och handelen 12. och fig. att handtagen 1 förts ihop och brytorganen 5 genom hävstångs- verkan särat handelen 11 från hondelen 10.In Fig. 1 and Fig. 1A the embodiment is shown in its rest position, i.e. the position where the jaws 3 are brought together due to the action of the spring 4. The connector to be disassembled is indicated by dashed lines in the various drawing figures and the device consists of a female part 10 and a handle 11. In Figs. 1, 3 and 5 are shows how the breaking means 5 are inserted into the groove 12 which in Fig. 24 shows the position where the splicing device is disassembled through is formed in the joint between the female part 10 and the trade 12 and shows that the handles 1 are brought together and the breaking means 5 separated by lever action. trade 11 from female part 10.

I den i fig. 3 och 4 visade utföringsformen av anord- ningen enligt uppfinningen har endast den ena av gripkäftarna 3 en länkarm 6 och vid utföringsformen enligt fig. 5 saknas överhuvudtaget en länkarm, vilket innebär att brytorganen 5 är fästa direkt på gripkäftarna 3.In the embodiment of the device according to the invention shown in Figs. 3 and 4, only one of the gripping jaws 3 has a link arm 6 and in the embodiment according to Fig. 5 there is no link arm at all, which means that the breaking means 5 are attached directly to the gripping jaws 3.

Claims
