Abstract

In order to make it possible to fit multipole plug-in connections easily, low plugging forces are required. This is achieved according to the invention with an electrical plug-in connection (1) by, in the case of a vertical plug-in direction (arrow direction 17) for assembling the plug (2) and the mating plug (3), a horizontal contact-making direction (arrow direction 19) being achieved which makes contact between the male multipoint connectors (6) of the mating plug (3) and the contacts (12) of the plug (2).

Description

Plug-in power reduced electrical plug connection

The invention relates to a steckkraftreduzierte electrical connector consisting of a multi-pin connector and a corresponding thereto multi-pole mating connector, wherein the mating connector comprises male connectors which cooperate with manufactured electrical connector with contacts of the plug, said prepared connector is losbar again.

State of the art

According to the prior art, the contacting of electrical plug-in connections takes place by a stacking of the contacts on the male connectors. For example, the plug includes contacts and the mating connector male connectors. Here advertising the contacts are plugged almost vertically in the insertion direction of the plug on the mating connector and thus on the male connectors. As a rule, have the contacts flexible elements, so-called ^¬ contact springs. These practice contact normal forces, which act when mated on the male connectors, to ensure a secure contact. However, in the case of plug-on and plug-in processes, beyond the contact normal forces, plug-in forces must be overcome which arise as a result of friction, but also due to the contacting of the housings of the individual plugs.

In general, it is possible in electrical connectors that have a few poles, interpret the insertion force such that it is ergonomic ausfuhrbar.

If multi-pin plug are present, different Losansansatz, in particular so-called Andrucksteckverbinder are known in which additional forces are applied for the bringing about of the electrical connector via lever or lever technology or rotation mechanisms.

According to DE 22 45 033 Al an electrical connector for motor vehicles is known. A so-called pressure connector has in its housing a plurality of Einöffoffnungen in which contact springs are mounted. By means of a rotatable selector shaft, an actuating device for pressing and releasing contacts is moved.

From DE 23 49 415 Al an electrical connector is ^¬ known, in which the plug by means of a protruding in the insertion direction over the first connector locking device the mating connector is lockable, wherein the locking device is connected to an actuating device. However, the actuating device leads a rotational BEWE ^¬ supply from.

From US 4,627,481 a pressure connector for an electrical system is known in which in a first Ste ^¬ ckerteil arranged contacts by means of a Betatigungseinrich- device with attached in a second connector part mating contacts are detachably connectable, wherein the electrical connections by importing the mating contacts takes place in the contacts and wherein by a linear movement of the actuating device within the first electrical contacts having the plug part, the electrical contacts are each fixed with an electrical counter-contact.

Disadvantages of the prior art

The prior art has the particular disadvantage that multipole connectors, the insertion forces that are applied for the individual contacts, add, so that increased insertion forces are necessary. Around the plug forces to überwin ^¬, the prior art complex solutions by means of levers or other mechanisms or shift shafts are superiors beat invention. However, these require a high design effort and are also costly to manufacture.

To be applied to the forces to make the contact is also the insertion force to add, which arises because the two connectors, ie a plug and a mating connector be merged with their individual housings. Corresponding Reibkrafte between the two housings, in particular by sealing elements are also overcome.

Object of the invention

The object of the invention is to design the mountability of multi-pin plug connections in such a way that only small plug-in forces are necessary to bring about the electrical plug connection.

Solution of the task

The core idea of the solution of the task is a bond Steckver ^¬ propose will be drawn in the case of a vertical insertion direction of the plug and mating plug a differently directed Kontaktie- approach direction to effect the contacting between the contact and male connectors.

Thus, it is proposed as a solution to arrange the contacts on a comb-like element within the connector and to make the comb-like element within the connector movable namely in such a way that can be brought into engagement by changing the position of the comb-like element during or after bringing the connector male connectors are.

Advantages of the invention

An advantage of the invention is that multi-pole plug ^¬ connections can be produced with a reduced insertion force. This is inventively achieved in that the actual insertion force and the contacting force to bring about the contacting between male and male contacts are separated.

First, plug and mating connector are guided against each other and preferably inserted vertically in an axis to each other. Are plug and mating plug guided into each other, so penetrate male connectors, which are arranged within the mating connector, a displaceable within the plug perpendicular to the insertion direction mounted comb-like element. The comb-like element has in the same locking measure as the arrangement of the knife ^¬ afford within the comb-like element recesses, which can be penetrated by the male connectors in the inserted state. These recesses have a size which corresponds at least to the cross section of the respective male connectors. The recesses are electrically isolated, so that in addition to a possible, but not mandatory mechanical contact between the plug and mating connector no further contacting takes place.

This comb-like element has a flat, planar design. Preferably, the corresponding recesses are honeycomb-shaped, the individual honeycombs comprising two regions. The first area serves to accommodate the male connector during the vertical insertion process. No or only a small amount of force is needed to insert the male connector into this honeycomb introduce formal education. The second region is configured such that it adjoins the first region spatially, but is dimensioned such that the contact arranged within the further region contacts the respective male connector. The respective contact itself is connected to an electrical ^¬ rule conductor, which is guided in each case from the plug.

The comb-like element is arranged in such ^¬ inside the plug, that when plugging the plug on the mating connector, the male connectors of the mating connector are received in the first region of the comb-like element. By further plugging the plug perpendicular to the mating connector is achieved by a order ^¬ steering that shifts the comb-like element horizontally within the plug and thus pass over the male connectors from the first area in the second area and contacted by the disposed on the comb-like contact become .

In a preferred embodiment, the contacts, which are arranged on the comb-like element, spring-like disposed within this honeycomb formation.

A further embodiment according to the invention consists in that the contacts consist of metallic clips which can be plugged into the honeycomb form.

Because of this spring-like configuration of the contacts, there is again the advantage that shaking and shaking motions as well as fretting corrosion between male connectors and contacts can at least partially be compensated. The comb-like element, together with the contacts, can be moved in different ways within the plug in horizontal ^¬ ler direction.

The simplest embodiment is that after production of a primary locking between plug and mating plug by a further actuation, for example by horizontal Ver ^¬ push the comb-like element, the contacts with the knife strips are engageable. For this purpose, it is also proposed se vorteilhafterwei ^¬ that corresponding actuating elements are defined at the outer walls of the plug to be a simple operation to enable the comb-like element.

A further inventive and advantageous embodiment of the comb-like element is that this is arranged on ramps or scenes, which are designed such that by further execution of the insertion movement in the vertical direction, the comb-like element is guided automatically in the horizontal direction.

A particular embodiment is that when on ^¬ mating process of connector and mating connector, first the male connectors penetrate the comb-like element at least partially and simultaneously or subsequently the comb-like element comes with a slide in engagement, which is arranged inside the counter ^¬ plug. The gate has at least one ball ^¬ senbahn, which is designed such that by the Verti ^¬ cal movement of the plug on the mating connector horizontal movement of the comb-like element is exercised. This will result Advantageously that by the execution of the vertical ^¬ movement of plug and mating connector to each other, the contacting between male connectors and contacts in the comb-like element is done automatically.

Another embodiment of the scenery may consist in that the backdrop is formed like a ramp, wherein at the end of the ramp, a latching of the comb-like element takes place. This brings the particular advantage that a secure contact takes place. Only by destroying this locking connection can be done a solution of the connector between the plug and mating connector.

It is not necessary that the scenes themselves are located within the mating connector. Rather, the scenes can be mounted anywhere on plug and mating connector where they cause the detached from the vertical direction further movement ^¬ direction of the comb-like element.

A further advantageous embodiment of the invention may consist in that the comb-like element is simultaneously formed as a secondary lock. In addition to the two tasks causes the secondary lock here a releasable locking between the plug and mating connector.

A not insignificant advantage of the invention is that within the inventive connector, consisting of plug and mating connector, together with the comb-like element to bring about the contact between the contacts and the male connectors, there is sufficient space to to arrange a secondary lock. Therefore, regardless of whether a multi-pin connector with or without secondary lock is formed, the inventive design can be applied.

Further advantageous embodiments will become apparent from the following description, the drawings and the claims.

In Figure 1, the electrical connector 1 is shown in perspective partially in section. The electrical Termina ^¬ dung 1 consists essentially of a connector 2 and a corresponding connector 2 with the mating connector 3. The mating connector 3 is coupled telbar, in the illustrated exemplary embodiment UNMIT ^¬ with an aggregate. 4 The mating connector 3 comprises a housing 5, wherein inside the housing 5 male connectors 6 are provided in different or gleichmaßiger arrangement. For reasons of simplification, only a few male connectors 6 are shown here. The male connectors 6 are formed pin-like in the embodiment shown here and aligned ^¬ tet so that they point in the direction of the plug 2. Furthermore, they are aligned parallel to the plug-in direction 17 of the plug 2 and mating connector 3.

The plug 2 comprises in the exemplary embodiment shown here, a comb-like element 7, which is preferably flat ausgebil ^¬ det and a plurality of honeycomb 8 shows.

The honeycomb 8, as shown in more detail in Figures 3 and 4, essentially comprise two areas.

The first region 9 of the respective honeycomb 8 is formed in such a way that the male strips 6 arranged in the mating connector 3 can be passed through the comb-like element 7 at least partially unhindered. In the region of the constrictions, ie in the wider region 10 of the honeycomb 8, which are formed in particular by a narrowing of the respective diameter of the honeycomb 8, there is the so-called contacting region 11. Within of the contacting region 11, the arrangement of contacts 12 of the plug 2 is provided. These contacts 12 are preferably formed like a clip and have metallic surfaces. Their distance from one another is dimensioned such that they have at least the width of the blade strips 6 or a smaller width ^¬.

Furthermore, the comb-like element 7, as shown in Figures 1 and 2, recesses 14 and 15 Fuhrungsmittel. The recesses 14, which are arranged centrally and at a distance zuein ^¬ other in the illustrated embodiment of the comb-like element 7, interact with scenes 16 (Figure 1), which are arranged within the mating connector 3, together.

In bringing about the electrical connector 1 by driving the plug 2 in the insertion direction 17 on the mating connector 3, as shown in Fig. 1, the plug 2 is first inserted into the mating connector 3. Once a leadership takes place and the corresponding insertion force is overcome, the comb-like element 7 and its recesses 14 comes with the corresponding Fuhrungsmitteln 15 into engagement. The scenes 16 have slide tracks 18 in which the recesses 14 and the guide means 15 of the comb-like element 7 slide. By Verti ^¬ cal movement of the plug 2 in the insertion direction 17, the comb-like element 7 is first guided in the same direction until the male connectors 6 have penetrated the first portion 9 of the honeycomb 8 at least partially. As soon as this area is reached, the recess 14 (FIG. 2) and its guiding means 15 (FIG. 2) of the comb-like element 7 also contact the scenes 16. By advancing the plug 2 in the plugging direction 17 causes the comb-like element 7 along the slide 16 in particular the recesses 14 are guided in the slide tracks 18, whereby a horizontal movement (arrow 19) of the comb-like element 7 takes place. This movement of the comb-like element 7 in this direction of the arrow 19 causes the male connectors 6, which have penetrated this first region 9 of the honeycomb 8, to be transferred into the further region 10 and reach the contacting region 11 shown in FIG , Within the contacting region 11, the arranged contacts 12 make contact with the male connectors 6. On the individual contacting regions 11, as shown schematically in FIG. 1 for a contacting region 11, contact holders 20 are provided. These contact holders 20 serve to receive a cable of a wiring harness (not shown in the drawings) guided in the connector 2 and to provide an electrical connector 1 between the cable and the contact 12 within the contacting portion 11 of the comb-like member 7.

Preferably, spring-like elements are provided within the counter ^¬ plug 3, which cause the comb-like element 7 is ent ^¬ moves against the horizontal movement (arrow 19) along the slide track 18 when removing the plug 2 from the mating connector 3, and so far to the knife strips 6 are released again from the comb-like element 7.
