ABSTRACT:
The invention relates to an electric plug connector comprising a carrier body consisting of insulating material and a plurality of segments, inserted into the carrier body, with contacts and terminals.
A complementary plug connector is plugged into such a connector, which can have the form of a spring-contact strip or blade-contact strip, to form a multipolar plug connection. The segments inserted one beside another into the carrier body of the plug connector bear contacts on the side which is introduced into the carrier body, said contacts having the form of contact springs in the case of a spring-contact strip or contact blades in the case of a blade-contact strip and serving to establish the contact with the corresponding contact blades or contact springs of the complementary plug connector. Terminals connected to the respective contacts are formed on another side of the segments, which terminals can be connected for example to circuit board leads. Here the terminals can extend at right angles to the plug-in direction of the plug connector.
The segments, with their contacts and terminals, are produced in various forms. In one method of production the contacts are extrusion-coated, although this is relatively costly. In another method the segments consist of two parts and the contacts are inserted between the two segment halves. This has the disadvantage, however, that considerably more individual parts must be processed overall. Finally, the contacts can also simply be inserted in discs, although this has a disadvantageous effect on their tightness of fit.
German OS 196 34 844 and German Patent 195 33 295 have disclosed housings into which an inner housing can be inserted. A cover or cap is used to define the inner housing in the actual housing.
The object of the invention is to provide an electric plug connector designed in accordance with segment technology wherein the segments are reliably, precisely and firmly installed in the plug connector with a simple and thus cost-effective assembly.
This object is achieved by means of an electric plug connector comprising a carrier body consisting of insulating material and a plurality of segments, inserted into the carrier body, with contacts and terminals, wherein an additional member consisting of insulating material is provided which fixes the segments in the carrier body and is provided with comb-like projections arranged between the segments. Such an additional member provides for a firm retention of the segments in the carrier body and has the advantage that it additionally serves to insulate the segments from one another and thus leads to an improvement in respect of the required creepage distances and clearances in the plug connector, these being undesirable in plug connectors.
Preferably, the terminals of the segments are connectible at right angles to the plug-in direction of the contacts so as to obtain an advantageous plug connection configuration in the case of which the terminals of the segments project at right angles to the plug-in direction of the plug connector, for example into corresponding bores of a circuit board. A plug connector can thus be plugged-in in space-saving manner in the longitudinal direction of the board.
It also proves advantageous to provide the additional member with projections for fixing the contacts of the segments inserted into the carrier body so as to facilitate their precise positioning. This can be achieved particularly easily when the contacts are offset and engage with the projections of the additional member. Reliable contacting of the segment contacts with the corresponding contacts of the complementary plug connector is then ensured.
Further improved fixing of the segments and their contacts can be achieved by means of different additional measures. Thus for example a bearing surface of the additional member can press against a first end surface of each segment facing away from the contacts and can thus press a second end surface of the segment, disposed opposite the first end surface, onto a stop of the carrier body, thereby defining the insertion depth of the segments into the carrier body. Fixing of the segments transversely to their plug-in direction is facilitated by rib-like projections of the additional member which in each case engage into a corresponding recess in the first end surface of a segment. Finally the outer segments of the plug connector can preferably be retained by means of a protrusion of the bearing surface of the additional member, which protrusion engages into a corresponding recess of the first end surface of a segment.
For an optimal fit of the additional member in the carrier body, the additional member preferably comprises sprung detents which engage into corresponding locating openings of the carrier body and thus facilitate firm locking. For this purpose, a support wall in the carrier body can also be provided with ribs, said ribs in each case comprising a cut-out into which a corresponding integral protuberance of the additional member engages.
Finally, for the rapid and simple disassembly of the plug connector into its individual parts, it has proved advantageous for the carrier body and the segments to be held together only by means of the additional member.
