Abstract

The flat ribbon cable [6] fits into a slot in a hinge mounted actuator block [18] that is secured to a housing element [13]. Set into this are a line of connector pins [14] that have blade contacts [15] that pierce the insulation and contact the conductors of the ribbon cable. The ends of the contact pins are fixed to a circuit board [5] in the main housing.

Description

The invention relates to a connection device for connecting parallel offset from each other in one or more levels lying conductor, in particular a ribbon cable, according to the preamble of claim 1.

Such connection devices are known per se in a variety of embodiments and have proven themselves. In addition to low production costs is the ease of use an important prerequisite for market success. The solution to this problem is the object of the invention.

The invention solves this problem by the subject matter of claim 1. Advantageous Embodiments are to be taken from the subclaims.

According to claim 1, an actuating clamping piece is provided, which in particular Pivot pin preferably in grooves of the connection base insertable and at this is pivotable, wherein the first connection base a U-shaped pivot space in which the actuating clamping element pivoted in its clamping position is and wherein the actuating clamping element insertion openings for the end portions the conductor to be contacted and / or the cable to be contacted, and on its side facing the connection base openings for the insulation piercing contacts, so that all conductors with only a single Pivoting movement are contactable.

Such results in a simple structural design, a connection device, the a simple and precise connection of the conductors form a particular ribbon cable or in a row of adjacent conductors in isolationsdurchdringender Connection technology with only a "handle" allows.

The insulation piercing contacts may be formed as piercing contacts, in particular such that they also penetrate a cable sheath or as IDC fork contacts for penetrating the insulation of individual conductors.

According to a variant, the connection base has a base housing, which has a Having peripheral flange, directly on a peripheral area surrounding a breakthrough the wall of a housing can be placed.

But it is also a variant feasible, in which the connection base in an advantageous Way is designed as an easy to handle "free" plug part, the one Has holding or clamping clip.

1a and b and 2 show a housing 1 with a base 2 and a lid 3, that for receiving an electronic assembly 4, here a populated printed circuit board 5, is designed.

To the electronics assembly 4 more parallel to each other in a plane (or multi-level) lying conductor 6 to connect insulation penetrating, the may be arranged in the manner of a ribbon cable 7 or e.g. the leader of an im Endband can be stripped flat cable, is a wall 8 of the housing 1 provided with at least one or a plurality of apertures 9, on which in each case a socket-like connection base 10 can be placed, each one the openings penetrated and out of the housing 1 from the opening 9 to the outside protrudes.

The connection base 10 has a base housing 11, which has a peripheral flange 12, which directly on a breakthrough 9 surrounding edge region the wall 8 of the housing 1 rests.

A here exemplary stepwise tapered housing portion 13 of the connection base 10 extends into the opening 9 in the housing 1, and Although here to the circuit board 5.

For use in harsh conditions, it is desirable to have such a connection device also in sealed design. On the outer circumference of the extending into the opening 9 in the housing portion 13 of the connection base 10 and the wall 8 and the opening 9 is therefore a sealing ring 16th arranged, which can be molded, for example, to the connection base and on outer circumferential ring-like projections 17 which has the wall 8 of the housing sealingly engage behind.

Pins 14 of conductive material pass through the circuit board 5 and the socket housing 11 to in a cross-sectionally U-shaped pivot space 23 of the base housing 11 at his facing away from the housing 1 top inside. At the free ends of the pins 14th are each insulation penetrating contacts 15 - here fork-like IDC cutting contacts 15 - arranged, which for isolationsdurchdringenden contact the conductor 6 are formed, wherein about the pins 14 in the transition region to the insulation penetrating Contacts 15 a seal 35 is molded, the sealing and also has an advantageous stabilizing effect when the connection device is closed becomes.

Here are several of the IDC cutting contacts 15 in two rows offset from one another in such a way arranged that easily also several close parallel adjacent conductors. 6 are contactable.

To contact the conductors 6 in a simple and precise manner and with sufficient force or insert here in the IDC cutting contacts 15, is an actuating clamping element 18 is provided, which has a housing 19, on the side two Pivot pin 20 are formed, in which the housing 16 in two corresponding Grooves 21 on the housing 19 initially inserted (direction Z) and then pivoted is to the ladder 6 when swinging together with only one movement in the insulation penetrating Press contacts 15.

The housing 19 of the actuating element 18 has an elongated shape and Such dimensions that it in the contact position or pivoted position largely the pivot space 23 at the top of the plug base 10 fills. It is provided with a plurality of mutually parallel insertion channels 22, in which the free ends of the conductors 6 are inserted, so that these with defined position to each other are arranged. The pivot pins 20 are opposite to the insertion channels 22 Pages 19 of the housing 19 of the actuating clamping elements 18 are arranged. The insertion channels 22 widen at their leading end from the housing an overarching receiving space 27, in which a seal, in particular a sealing ring 28 can be inserted (insertion direction x), which surrounds the conductor 6.

Perpendicular to the insertion X for the ladder openings 24 extend through in the pivoting position to the plug base 10 facing wall 25 of the housing 19, which are designed so that through them the insulation piercing contacts 15 precisely are led directly to the ladders when swiveling the housing 19 until they penetrate their insulation, so that the contacting position of FIG results.

Locking lugs 26 on the actuating clamping element 18 are used for locking the actuating clamping element 18 in the contacting position of Figure 2 on the plug base 10, in they latching in not recognizable recesses or the like on the plug base 10 intervene.

The insulation piercing contacts do not need as IDC fork contacts but can be realized by Piercingkontakte 15 ', which needle the line insulation or penetrate like a knife (Fig. 4). Preference is given to several curved in itself knife-like piercing 15 'used with a blade-like blade tip 29.

In the embodiment of Fig. 4, the connection base 10 is as elongated free plug part 30 with a holder and / or clamping clip 31 to hold or Clamping, e.g. realized on a wall (not shown here), from the U-shaped Receiving space 23, the piercing contacts 15 'protrude outward.

To the piercing 15 'busbar pieces 32 are formed, which on the remote from the receiving space end of the connector part 30 in insertion channels 33 for Plug pins, ladder or the like. A sealing ring 34 allows the sealed Connection of another plug part or the like .. The Betätigungsklemmsockel 18 corresponds in terms of its design and handling of the embodiment from Fig. 1, however, the insertion channels as a cross-insertion opening 22 for the ribbon cable 7 is formed with a jacket, allowing a connection of the entire cable 7 without stripping with only one pivoting movement is possible because the piercing contacts 15 'penetrate both the cable sheath and possibly the conductor insulation.
