Definitions
- the invention relates to a miniaturized electrical plug made of plastic for low-voltage systems, in particular telecommunications technology, preferably for telephone systems according to the preamble of claim 1.
- a known plug of this type consists of a plug housing in which a block-shaped plug insert element is mounted.
- the housing only surrounds the plug insert element, the latter receiving the cores of a multi-core, flat Lahnlitze réelle arranged in a row next to each other and supports one-piece metallic contact elements which have a plug contact area and a core contact part.
- the wire contact part penetrates the insulating jacket of a wire of a stripped area of the Lahnlitzetechnisch and contacts the metal strip, the z. B. is spirally wrapped around a nylon core.
- the contact area of the wire contact part consists of two acute-angled cutting edges arranged one behind the other in the longitudinal direction of the wire and which have penetrated into the wire.
- the object of the invention is to provide a simple three-dimensional shape for an electrical connector, which enables simple threading of the wires of a Lahnlitze effet and controlled contacting of the wires.
- the plug according to the invention is preferably designed as an angled plug and constructed in two parts and consists of the housing part 1 and the plug part 2 mounted in the housing part, these parts preferably being locked together.
- the plug part 2 has a connector strip 4 projecting downward from the housing part 1 and a bearing block 5 seated in the housing part 1. Viewed in plan view (FIG. 3), parts 4 and 5 are square, the tongue 4 being narrower than bearing block 5 (FIGS. 1, 1 b).
- the bearing block 5 has slit-shaped, narrow passages 3, which are expediently three in the longitudinal direction of the part 2 in two rows arranged side by side, the clear lateral distance of the two rows corresponds to the width of the bar 4 and the passages 3 the bearing block 5 in the direction push through the bar 4.
- On the bar 4 z. B. four equally spaced ribs 6, which project vertically downwards and viewed in cross section, form U-shaped grooves 8 in the strip 4.
- longitudinally extending grooves 7 can also be introduced superficially, which run from a front passage 3 to the height of the rear passages 3 and end between the rear passages 3 of the two rows (e.g. FIG. 3).
- each contact web 9 of a contact element 10 consisting of a strip-shaped sheet-metal stamped part are stored in the U-shaped grooves 8, the contact elements 10 being particularly fastened and fixed in position in the bearing block 5, for which purpose suitable means known per se are used (not shown).
- the extension of each contact web 9 passes through a passage 3 and merges into the wire contact tongue 11, which projects vertically standing above the surface of the bearing block 5.
- the contact elements 10 seated in the front grooves 8 have connecting webs 12, which preferably extend from the webs 9 at right angles to the rear, sit in the grooves 7 and to which the wire contact tongues 11 extending upwards at right angles are connected.
- wire contact tongues 11 viewed in the transverse direction of the plug, are arranged next to one another at a distance and project vertically upwards.
- the upper edge 13 of the contact tongues 11 is designed in the form of a cutting edge and expediently has two bump-like, rounded penetrating cutting edges 14 when viewed in side view (FIG. 2).
- the housing part 1 has a bottom 16 and two side walls 17, wherein preferably a front wall 18 can also be provided.
- a core block 19 is preferably arranged in one piece, that of the bottom 16, after protrudes below into the interior of the housing.
- the block 19 is made narrower than the clear distance between the side walls 17, so that gaps 20 remain next to the block.
- the block 19 is preferably also shorter than the length of the housing and is located in the area of the wire contact tongues 11 of the contact elements 10.
- the core block 19 has, viewed from behind, in a horizontal plane next to each other at a distance from each other holes, preferably blind holes 21, which extend forward. Starting from approximately the longitudinal center of these holes 21, a passage formed as a longitudinal slot 22 passes through the block 19, the cross-sectional shape of which corresponds to the cross-sectional shape of a wire contact tongue 11, so that the wire contact tongues 11 sit positively in the slots 22.
- depressions 23 are expediently made, which are similar to the cross-sectional shape of the slots 22.
- the holes 21 preferably begin in a funnel shape, so that an insertion funnel 24 is formed.
- the wire contact tongues 11 sit in the slots 22 and protrude with their cutting edges 14 into the holes 21, wherein in each hole 21 there is a wire 29 of the Lahnlitze line 26, into which the cutting edges 14 have penetrated in a contacting manner (FIGS. 1 b and 2).
- the connector according to the invention can be supplied equipped with contact elements 10 and that contact can be made with a braided wire afterwards. For this purpose, it is ensured that the contact tongues 11 do not protrude into the holes 21 in the delivered state of the plug and can be inserted into the holes if, for. B. the wires 29 have been inserted into the holes 21.
- a pre-locking position of the housing part on the plug part 2 is provided for this purpose.
- the Vorraststeliung z. B. be ensured by at least two, the surface of the bearing blocks 5 in the outside area projecting locking webs 30 with an outwardly facing locking lug 31, the locking webs 30 projecting into the space 20 and the locking lugs 31 engaging behind locking edges 32, 32a, which in the side walls 17 are introduced, wherein the side walls and / or the locking webs 30 can deflect elastically resiliently inwards or outwards.
- the locking edges 32a are lower than the locking edges 32, i. H. below the locking edges 32, and mark the pre-locking position of the plug, d. that is, the distance between the locking edges 32 and 32a corresponds exactly to the desired positions of the wire contact tongues 11.
- the lower surface of the block 19 sits on the surface of the bearing block 5, which also results in a precise limitation of the collapsibility of parts 1 and 2. 1a, the surfaces are at a distance and the contact tongues 11 already protrude into the slots 22, so that the tongues 11 are already fixed in position. To simplify the insertion of the tongues 11 into the slots 22, the mouths 22a of the slots 22 are widened in a funnel shape.
- the core block 19 is located in a cutout 32 in the bottom 16 of the housing part 1 and is expediently fastened to the walls 17 with thin tab-like webs 36.
- the webs 36 enable the core block 19 to be moved in the direction of the double arrow 37.
- the housing part 1 is z. B. suitable locking means on the plug part 2, wherein the core block 19 is at a distance above the surface of the bearing block 5 (not shown).
- the contact tongues 11 do not protrude into the holes 21, but already into the slots 22. If the wires 29 are inserted into the holes 21, the wire block 19 is pressed down, the tab-like webs 36 giving way, e.g. B. stretch due to their excess width or, if they are elastic, stretch.
- the contact tongues 11 penetrate into the wires 29 until the lower surface of the wire block 19 strikes the surface of the bearing block 5 and suitable latching means which act between the housing part 1 and the wire block 19 (not shown) snap in, so that the wire block 19 is fixed in position becomes.
- suitable latching means which act between the housing part 1 and the wire block 19 (not shown) snap in, so that the wire block 19 is fixed in position becomes.
- the fastening webs 36 can also be severed.
- the novel construction of the plug according to the invention also allows strain reliefs to be provided which act on a wire 29 and / or on the sheath of the Lahnlitze Ober 26, without curvatures or the like. Deformations that displace the wire or the sheath spatially outwards.
- a bar 38 is arranged for the strain relief in the rear area and extends transversely across the surfaces of the bearing block 5 with a cutting edge 39, which passes through a perforated slot 40 in the bottom of the chamber-shaped opening 25 of the wire block 19 and is pressed into the sheath of the Lahnlitze line 26.
- a strain relief device can be provided for each wire 29 (FIG. 4).
- a mandrel 41 passes through a hole 40 that extends into a hole 21 and presses into the wire 29.
- the invention solves the problem shown by shifting the tasks on the one hand into the housing part and on the other hand into the plug part 2.
- the housing part contains the bearing elements for the wires, and the plug part supports the contact elements, the assembly of the two parts causing the intrusion contact.
- Multi-part connectors with certain functional tasks of the parts with regard to ensuring the contacting are known in the generic subject area (US Pat. No. 3,761,869).
- the wires are placed between two parts of the connector and the parts are joined, the wires being clamped.
- the two-part embodiment has not proven itself because the positioning of the wires and thus the precisely controllable penetration of the contact elements into the wires is almost impossible.
- the contact elements are pressed in individually after all the wires have already been inserted into a slot. The wires can move laterally, so that the contact can be disturbed.
- the invention has gone back one step and has taken up the two-part embodiment of a plug again, but has found a solution that ensures an optimal distribution of functions.
- the wire contact tongues 11 have barb-shaped material projections 11 on their outer edges, which are arranged in such a way that when the housing part 1 engages with the plug part 2 they penetrate into the wall of a slot 22 and get caught there.
- barbed material projections 10a are provided, which ensure a fixed positioning of the contact elements 10 in the bearing block 5.
- the barb-shaped material projections 11a In combination with the barb-shaped material projections 11a, when the housing part 1 is locked with the plug part 2, the parts 1 and 2 are also held together by the positioning means 11a and 10.
- a major advantage of the invention compared to the prior art is that the contact elements 10 sit immovably in their bearing block 5 and only the wire block 19 is pushed onto the contact webs 11 for contacting without the position of the contact elements in the bearing block 5 being changed. This arrangement results in controlled contacting of the wires. This is not possible with the known plugs, in which at least some of the contact elements had to be moved in their bearing block in order to make contact.
