Definitions
- the invention relates to an electrical connector part a housing made of plastic with at least one row of adjacent, receiving chambers separated from one another by crosspieces for the contact elements and at least one piece on the outer housing wall molded, which can be brought from an open position into a locking position, locking arm pivotable about an axis, the cross section of which L-shaped and the cross-section of the respective in the open position Receiving chambers and the cross-section in the locked position narrowed and thereby the contact element located between one End stop and the free end of the locking arm holds, this free End protrudes through at least one opening in the housing and the locking arm is locked in the locking position relative to the housing.
- each receiving chamber is a locking arm assigned, which either locks in its locked position or by a second housing part pushed onto the housing in its locking position is held (EP 0164 211 B1; DE 39 33 959 C2; DE 43 01 602 C1). Since such connector parts have very small dimensions, that is are small, these constructions are extraordinarily delicate and those for yours Manufacturing required injection molding tools extremely expensive and complicated and therefore prone to failure.
- the invention is based on this state of the art and aims at to design an electrical connector part so that it with comparatively simple and therefore robust tools can be manufactured, but above all, the connector part is to be designed so that it on production machines is manipulable and that its locking the required high can withstand mechanical loads.
- the locking of the contact elements, short legs of the locking arm and those for its inclusion in the housing extend the recessed opening across the row of the receiving chambers, being in the open position of the locking arm between an edge of the Opening and the free edge of the short leg at least one as a predetermined breaking point serving web is provided and at least one transverse to the Receiving chambers extending boundary edges of the opening the swivel path of the small leg of the locking arm cuts and the small one Leg held in the locking position within the housing is, wherein the locking edge opposite the axis of the locking arm the free end of the short leg is at a distance from this axis, which is a little smaller than the distance between those adjacent to the axis Boundary edge of the opening of this axis and the short leg of the locking arm is formed in one piece over its entire length.
- the electrical connector part has a housing 1 made of an electrical insulating plastic material and has essentially a rectangular, cuboid Shape up.
- This connector part is designed as an injection molded part.
- In this box-like housing 1 are separated by a row spaced, side by side cross bars 2 receiving chambers 3 recessed, in which contact elements can be used. Such contact elements will be offered in stores. Openings 5 are left in the upper end face 4, through which the pin-shaped contact elements of a second connector part are insertable, but are not shown here.
- a locking arm 6 On the front Broadside 13 of the housing 1 (Fig. 1) is formed a locking arm 6, the extends essentially over the width D of the housing 1 and its here axis 7 lying below, about which this locking arm 6 can be pivoted, is formed by a film hinge 8.
- the locking arm 6 has an L-shaped Cross section (Fig. 4) with a long leg 10 and a short one Leg 11, this short leg 11 on its free, the film hinge 8 facing end has a locking edge 12.
- the housing 1 In the front broad side 13 of the housing 1 is a, extending over its width D, slot-shaped opening 14 recessed in the swivel range of small leg 11 of the locking arm 6 and in the individual that For this purpose, receiving chambers for the cross webs delimiting the contact elements are provided correspondingly lying recesses 15, the inside edge 16 of this recess by a dimension T relative to the front broad side 13 of the housing 1 is set back, at least the length of the small leg 11 of the locking arm 6 corresponds.
- the lower boundary edge 17 of the slot-like Opening 14 intersects the swivel path of the small leg 11 or whose locking edge 12, as the curved line 18 in Fig. 5 indicates, the pivot path designated the locking edge 12.
- the two legs 10 and 11 of the locking arm 6 form an acute angle with each other.
- the short leg 11 of the locking arm 6 is integrally formed over its entire length.
- In the crossbars 2 of the receiving chambers 3 are those described above Recesses 15 recessed. If these cutouts on the crossbars 2 would not be present, are on the short leg 11 of the locking arm 6 incisions running in or parallel to the pivoting plane of this locking arm provided, in which in the locking position of the locking arm the transverse webs 2 dividing the receiving chambers 3 protrude.
- the exemplary embodiments according to FIGS. 4 and 5 are the webs 9 mentioned above provided at the top of the opening 14. It is also possible to use these bars on to arrange the lower edge of this opening 14. Instead of two bars, only a web can be provided or more than two webs.
- FIG. 6 now shows a vertical cross section like FIG. 5, but here is already one commercially available contact element 19 with an attached lead wire 20 inserted into the receiving chamber 3.
- This contact element 19 has resilient spreading wings 21, with which it itself in the receiving chamber 3 holds.
- the locking arm pressed against the housing 1 (arrow 22), with its short leg 11 in the illustrated here snaps and snaps into place while doing the part of the contact element 19 serving to connect the lead wire 20 engages positively and so a second fuse for the contact element forms.
- the locking edge 12 of the leg 11 passes over the lower boundary edge 17, this leg 1 being raised slightly and then as soon as the locking edge 12 has passed over the lower boundary edge 17, clicks and clicks into place.
- FIG. 7 a housing is shown, the two parallel rows of such receiving chambers 3 owns.
- slot-like Openings 14 and locking arms 6 are formed and formed so that the Housing 1 has a substantially symmetrical cross section.
- the contact element 19 is a receiving element Contact element formed.
- the housing according to the invention Measure can also be used where in the receiving chambers of the housing pin-shaped contact elements are arranged by the contact elements shown 19 are included in the establishment of the contact connection.
