Fire description ;

Device for pressing insulating sleeves onto electrical ones Connecting terminals.

It is common practice to have an electrical connection terminal crimped against the end of a wire therethrough to isolate that a sleeve of insulating material, e.g. B. made of polyvinyl chloride, pressed against the connecting terminal will. The sleeve can, for. 3. from a vibrating insertion funnel are fed to the dies of a pressing device and then pressed against the connecting terminal. A disadvantage of this known method of insulating an electrical connecting terminal is that . the sleeve is easily damaged or misaligned,

while it is moving from the insertion line to the dies, ι

A further disadvantage of this method is that

FIG. 3 shows a schematic longitudinal section through the pressure device, but with the pressure stamp is in its top dead center;

Figure 4a is an elevation along lines VIA-VIA of Figure 3;

FIG. 4b shows a view similar to that of FIG. 3, but with the pressure ram in FIG Position according to FIG. 2 is located;

FIG. 5 shows a partial longitudinal section through the pressing device, wherein the Andrücksteiapel is shown at the end of its work cycle.

Fig. 1 shows an uninterrupted chain ST. of insulating Sleeves SV which are axially aligned with one another j where each sleeve SV is connected to the next following sleeve SV by a web SL, which is made of the material of a Plastic piece consists such. B. from the material of a polyvinyl chloride Eohres from which the chain ST has been manufactured.

In the following, a device will now be made with reference to FIGS for pressing the sleeves SV onto electrical connection terminals described. The device includes a pressure plunger 70 (only partially shown) which is arranged so that it reciprocates in a vertical sighting of of a predetermined length by being driven by an electric motor (not shown) via a G-rod (not shown) is driven. The electric motor can be

the push button of a foot switch (not shown) via a "SinstoS clutch (not shown) are driven so that by pressing the foot switch the pressure stamp 70 automatically to a downward or working cycle and to an upward or return cycle is caused, after which the pressure ram 70 remains in its top dead center, until the foot switch is depressed the next quay.

The pressure die 70 carries pressure dies 72 and 74 with working surfaces 73 and 75 and a blade holder 76, in which a shear blade 78 is attached so that it slides between the holder 76 and a cover plate 80, which one has centrally arranged, downwardly open slot 82. The shear blade 78 has a shear edge 84 which is a pair from the shear blade 78 outgoing leg 86 bridged. A pin 88 extends at right angles to the shear blade 78 and protrudes through the one located in the cover plate 80 Slot 82 (Figs. 3 and 5). Its two-legged handle 90 is on a pivot pin 92, which is in a projection 94 of the Shear blade holder 76 is attached, rotatably mounted and clockwise (Fig. 4a and 4b) around the pivot pin 92 with the help a spring 96, which at one end on the pawl 90 and at its other end on the cover plate 80 is attached so that the left leg (FIGS. 4a and 4b) of the pawl 90 rests against the pin 88. On the one of the turning

pin / seen from the opposite side of the peder 96 the pawl 90 carries a pin 97 which protrudes laterally from the pawl 90. Sin stop pin 98 protrudes from a plate 100, which is adjustable in the sighting from left to right (Pig. 4a and 4b) on one Frame part 101 of the device is attached, v / above this channel is otherwise not shown. The blade holder 7δ and the pawl 90 located thereon can be moved together with the plunger 70 relative to the stop pin 98.

The device further comprises a support part which contains a base block 102, which carries feed plates 104 on which there are guide plates 106 which form a feed channel 108 (Fig. 2). A pressure block 110 is also attached to the plate 104 and is ^{pressed downwards by springs 112 (5 1} Xg. 2). A transport finger 114 with a gripper 116 is pressed down (Pig. 2, 3 and 5) by a peder (not shown) and is arranged in such a way that it moves to the left and right (Pig. 2 , 3 and 5) with the aid of drive means (not shown), e.g. B. a piston-cylinder arrangement,. ι can be powered.

On the 31ock 102, Andrückainboase 118 and 120 with work surfaces 122 and 124 are also attached, in alignment with the work surfaces 73 and 75 of the Andrück-

The device includes a rotatable spool (not shown) which is attached to the frame of the device or to a special holder (not shown) and around which a chain SS iron insulating sleeves SV can be wound.

While the pressure ram 70 is in its upper plumb point, as can be seen in Fig. 3, the end of the sleeve chain ST located on the spool is inserted into the groove 103 below the pressure block 110, which is raised manually for this purpose. The end of the bushing chain S ¹ I is further pushed under the hook 116 of the 'Iran sports finger 114 is lifted manually also for this purpose. The Druc'.iblock 110 and iüransportfinger 114 are then released again so that they ig under the 7th ^r MPACT their feathers in the in?. 3 return to the position shown. The blade 78 is now manually removed from the Pig. 4a is raised to the position shown in Fig. 4b, and the end of the sleeve chain SS is below the edge 84 of the

Shear blade 78 pushed through so that the first sleeve SV of the sleeve chain rests on the plate 126 and on the working surfaces 122 and 124 of the anvils, as in Pig. 3 is shown. The shear blade 78 is then released and falls back so that it enters the slot between the foremost sleeve SV and the next following sleeve SV ¹¹ with the shear edge 84 of the blade 78 resting on the web SL between these sleeves. The device is now ready for use.

3 an electrical connection corner C, e.g. B. a rod-shaped receiving clamp, which is already pressed against a wire \ I , is inserted into the foremost sleeve SV until the connecting clamp C abuts the shear plate 78, which, as mentioned before, is in the slot 3 between the sleeve 'SV and the next following sleeve 3V 'extends. Accordingly, the connecting cable is positioned exactly inside the sleeve SV in the axial direction.

By actuating the? Switch, the pressure ram 70 to a.-r. Work cycle caused so that the sleeve SV between the working surfaces 73 and 75 of the pressing dies 72 and 74 and the working surfaces 122 and 124 of the anvils 118 and 120 is pressed against the connecting clamp C. Vfährö of the work cycle, the blade holder 76 is guided downwards together rr.it dev -. ndrüc ^ steEpel 70 so that

the shear blade holder 76 moves relative to the shear blade 78 downward and the shear blade 78 abuts the base of the shear blade holder 75, whereby the shear blade 78 is driven down together with the shear blade holder 76, so that the shear edge 84 d'es shear blade 78 the web SL z \ between the foremost sleeve SV and the next following sleeve SV 'through the interaction with the shear plates 126 and 123 cuts. The shear edge 84 then enters the gap 132, as in Pig. 5 is shown.

The pressure ram 70 now automatically executes its return cycle under the action of the "Z5inschlag" clutch. During the pressure stamp 70 moves upwards and with him the shear blade holder 76, the pawl 90 pushes below the T ^'r irlcung its spring 96 the pin 88 located on the shearing blade 78 upward (Fig. 4b), so that the shearing blade 78 in its position pressing against the bottom surface of the shear blade holder and therefore moves upwards together with the shear blade holder 76, so that the shear edge 84 of the shear blade 78 is lifted over the next following sleeve SV 'and is thus positioned as one in the pig. 2 and 4b can see. The pin 97 located on the pawl 90 engages a microswitch (not shown) and actuates the drive means for the 2rap.sportfinger 114, so that the transport finger 114 has a working or left-hand motion.
