とのろう接に基づき、極めて費用がかかる。In the case of the known cable plug connectors, the cable connection type is based on a series of working steps required for each cable core, namely stripping the insulation of the cable core, twisting the core, tinning the core. Due to the pressing of the tinned core wire into the radial bore and the brazing with the plug-in contact element, it is very expensive.

In order to be able to arrange the plug contact elements of the type mentioned at the outset.

片を既に９０度だけ折り曲げることができる。For cable connection, the end piece of each insulated cable core is first inserted into the blind hole of the associated plug-in contact element and bent into the guide section of the slit by 90 degrees. In this case, the end of the cable core is located above the bottom of the blind hole by about the length of the cutting and tightening section of the slit. Naturally, the end pieces of the cable core can optionally be bent already 90 ° before insertion.

Contact the edge of the tightening section.

のろう接接続に匹敵する引張り負荷軽減作用及び保持作
用が得られる。従来の切断締付けの場合引張り負荷軽減
作用及び保持作用は極めて悪い。In this way, a contact contact comparable to a brazing connection between the cable core and the plug-in contact element can be achieved in a very simple manner with a significantly lower connection cost than before if the manufacturing costs are almost the same. At the same time, a tensile load reducing action and a holding action comparable to the brazing connection of the cable core are obtained. In the case of conventional cutting and tightening, the tensile load reducing effect and the holding effect are extremely poor.

簡単に行なうことはできない。Furthermore, the individual plug-in contact elements can be arranged very easily in the device by adjusting them to the respective pole pattern and then all plug-in contact elements can be pressed into the contact carrier at the same time. This is the case with known plug-in contact elements with radial holes (see FIG. 2).
It can't be done easily.

では費用が一層減少される。Furthermore, the high tensile strength of the cable core advantageously makes it possible to carry out direct injection molding without the use of auxiliary means, whereas in the case of the known cut-tightening, the large amounts that occur during injection molding. There is a risk that the contacts will disengage due to the force. This further reduces costs in the present invention.

しないからである。Furthermore, the plug-in contact element according to the invention is in particular
It is used to bring arbitrarily placed contacts into contact with a single core wire in a very narrow space. This is because, unlike the known ones, the end portions of the core wire do not protrude from the connection points.

素線の折損又は剪断が回避されるからである。Further, unlike the conventional case, the still insulated cable core wire is inserted into the bag hole,
There is no risk of changing the air gap and creepage distance due to a single leaking wire. This is because breakage or shearing of a single wire is avoided.

ことなしに行なうことができる。With the arrangement of the slits according to claim 2, a light clamping and thus pre-fixing of the cable cores is obtained, which pre-fixing then leads to the simultaneous pressing of all cable cores into the cutting clamping section. In addition, a very simple device can be used and in this case the procedure can be carried out without complications due to cable cores which are provided at different points of the guide section or which fall out.

く簡単にすることができる。A pre-folded cable core / end piece is inserted into the associated blind hole without incurring excessive costs due to the narrow annular collar formed by forming the blind hole according to claim 3. , The end piece has sufficient space in the blind hole so that it will not be significantly upset or compressed during the subsequent pushing of the cable core into the cutting and tightening section, and the cutting and tightening by back pressure It is inserted in the associated blind hole so that the safety of the connection is not adversely affected. This makes the assembly considerably easier without the use of any auxiliary means.

差込み深さが確実に得られなくなる。Theoretically, such an effect can also be obtained by a tapered blind hole narrowed toward the end on the insertion side. However, in this case, the desired insertion depth cannot be reliably obtained on the one hand on the basis of the unavoidable diametrical error and on the other hand on the basis of the end cross section, which is usually elliptical when the cable core is cut to length.

からである。On the other hand, it is advantageous if, as in the fourth aspect, the range on the connection side of the bag hole is tapered to the narrow annular collar. This makes it possible in a very simple manner to easily insert the respective cable core wire into the blind hole up to the annular collar and thus to insert it quickly during manufacture.

This configuration is also expensive in terms of manufacture (small diameter end section 6) as well as assembly (brazing connection).

And the wiring board is simultaneously used, without the use of additional aids, to simultaneously push in and hold all the cable cores in the cutting and tightening section of the slit.

Not only does it come into contact with the inner wall of the notch (C-press fit) and thus effective electrical contact, but at the same time it produces a satisfactory holding action for the wiring board.

とができる。The bent end of the core wire produces a high tensile load reducing action together with the cable core 17 held in the slit 27, and this tensile load reducing action cannot be obtained in the conventional cutting and tightening. Due to this high tensile strength, the plastic 36 can be directly injected despite the considerable force generated, unlike the known cutting and fastening methods.
