jQ related to things.

[Conventional technology and problems]

Such a connector is disclosed in West German Patent Publication No. 15389.
No. 19. In this case, a holding frame formed as a molded part of an insulating material latches and fixes the insulating plate hK provided on the I deflection of the laminated stator. The holding frame is provided on its side facing the bearing shield with a number of hollow chambers having large and small comb-shaped side openings. The small opening is used to accommodate the coil conductor end, and the large hookhole-shaped opening is in the form of a spring-like locking device and is used to accommodate the external connecting conductor. The 4th and 9th ends of the coil, which have been pre-bonded with the connecting conductor, are pushed into the pocket-shaped hollow chamber, and the coil is bent appropriately or molded with self-hardening casting resin in the hollow chamber (without tensile load from C). ℃・This holding frame is also used as an auxiliary thermal support to hold the breaker.
4, the thermal breaker can be attached to the claws of the holding frame.

Also known is the compact "K 3UJ Q'l" according to German Patent Application No. 2230806, the "towing engine housing" of which is provided with rails extending at a distance from each other, on which are made of injection-molded plastic. The manufactured component is pushed in until it hits the stopper and is latched, and this 114-component component is inserted into the four parts of the mandrel and has a concubine fitting. One end of the toy protruding (each small qt, the connection to the motive commutator h4' AI or brazing:) t, and the other end protruding from the component a plug-in sheath or plug-in tongue. The first light is secured to the four parts of the component with jaws so that it will not come off.The component into which the connecting tool is inserted is driven onto the laminated core. After latching, the commutator connection wires are brazed.

However, these above-mentioned structures are not necessarily suitable for converting a small-sized, single-motor processing line into an RRIIH.

[Purpose of the invention]

In the assembly process of the u The stator coil ends to be fixed and connected in a defined manner in other fixing forks with the terminals of the outer grid connection cables by means of individually caulked M-connections are then fixed, and then assembled. The assembled units are transported, for example, to two successive crimping stands which are different due to different wire diameters.

The width of the fixing forks 21, 22 and the spacing between them 411 is such that the width of the fixing forks 21, 22 and the spacing between them 411 is such that between the two grooves there is sufficient free space for the binding tool, in accordance with the laminated stator 8 located below it. Matched to groove pitch.

The length of the slit 14, which is provided to accommodate the end of the coil wire in the fixing fork, corresponds to the size of the coil end portion and the cross-sectional area of the stator coil end to be accommodated.

Introduce and fix the stator coil end into the fixing fork 21, 22 and swage it onto the plug-in tab 6, so that the crimped "active" plug-in tab 6 or the "passive" crimped connection 4n or 27 to complete the mounting of the lower part 2, the upper part 3 is folded back over the lower part 2 about the membrane hinge, and the lower part 3 is folded over the lower part 2 in the closed state. Place the latch bottle cap in part 2 into the latch opening 3 in upper part 3.
After 4, C is latched and they are fixed together. Upper fl (!1
When part 3 is folded over the lower part 2, the groove-shaped fixing fork 21.22Vi side wall 211.2210 is attached to the corresponding cover 31.32 which is additionally molded on the upper part.
Closed by.

Thereby it is advantageously mechanically impregnated and electrically insulated, especially in the radially outward direction against the capped bearing shield 8.4 (FIG. fi 1) in the final assembled state. 9 to 12 show i' of the closing cover 5 which is additionally molded via the facing connector case 4 and the membrane hinge 13.
P i ■ 1 structure is shown. Implementation” 1. The opposite connector case 4 (also formed as a block connector corresponding to the mounted connector cases 2 and 3) is designed so that the plug-in pin 77 corresponding to the plug-in pin 6 is the opposite connector. It is inserted into a pocket-shaped recess 48 of the case 4. A latch protrusion protruding from the insertion sheath 7 is used for fixing in the insertion direction and in the opposite direction. When inserted into the connector case, it is engaged and latched after the additionally molded launch cutout.The opposing connector case 4 has a membrane hinge 4.
A closing cover 5 is molded into the outlet side 41, which can be folded back to cover the outlet side 41 through the opening 3 to the position shown in broken lines in FIG.

As can be seen from Figure #10, one conductor end 91 of the outer power distribution network connection cable 9 is caulked to each plug-in sheath 7, led out through the outlet side 11, and then inserted into the upper part of the counter connector case 4. It is inserted into the additionally molded guide frame 44. Latch pins 42 are additionally molded on both sides of the guide frame 440, and when the closing cover 5 is folded over, the latch pins engage behind the latch protrusions 52 of the closing cover 5 and are latched.

For the mutual fixation of the connector housings 2, 3 on the one hand and the counter connector housing 4 with closing cover 5 on the other hand in the insertion direction and vice versa, the connector housings 2.
The latch key 2 is molded on both sides of the front insertion side of 3.
9 is used, and this launch key is latched by engaging with the corresponding latch hole 46 of the latch lever 45 provided on both sides of the opposing connector case 40 in the final assembled state.

In order to remove the connector case 2.3 and the opposite connector case 4 with a closing cover from each other, the latch hole 46 is aligned with the latch key 29, with the latch lever 45 centered around the molded part connecting it to the opposite connector case 4. It can be tilted outward to the extent that the threads are out of alignment. - As can be seen in particular from Figures 9 and 10, the other end is rotatably attached to the opposing connector case 4 via a membrane hinge 1τJ
At the free end of the shaped closure cover 5.

A cable clamp 51 is integrally additionally molded.

When the entire connector is in its final assembled state, i.e. in particular after the closing cover 5 has been folded back over the distribution network connection cable 9 inserted into the guide frame 44 and resting on the distribution network connection cable guide 37, the cable clamp is attached. 51 has a head on the cable clamp 51 side, and the connector case 2.51 has a head on the cable clamp 51 side.
It is tightened by a self-tapping screw that passes through the upper 1RII M15 through hole (capital) of 3 and is screwed into the square hole 20 provided in the lower 1A11 portion 2 of the connector cases 2 and 3. At that time, the cable clamp 5 is pressed from the outside.
