Description

Direct plug-in device with Vorjustiereinrichtung and relative to this sliding locking device

The invention relates to a direct plug-in device for direct plugging onto a printed circuit board.

It is known an arrangement for the electrical and mechanical connection of plug-in elements via a socket with a printed circuit board, which is designed for high electrical and mechanical requirements.

There are also known connection arrangements for printed circuit boards, which allows a direct insertion of a male part on a circuit board without attached to the circuit board socket.

WO 2012/107569 of the same applicant discloses a

Direct plug-in device for direct plugging onto a printed circuit board, wherein the direct plug-in device has a plug-in element, the one

Receiving housing and a plurality of recorded thereon pluggable contact elements. The direct plug-in device further has a plug element receptacle, which is configured for at least partially receiving the plug element such that in

absorbed state of the plug element, the plug element receiving the contact elements laterally at least partially covered. The

Steckelementaufnahme has at least one printed circuit board side arranged Vorjustierstruktur, by means of placing the

Plug element receptacle on the circuit board with at least one corresponding Vorjustierstruktur the circuit board is connected such that in the connected state, the contact elements to

correspondingly formed contact element openings of

PCB are aligned. The plug element is movable relative to the preassembled on the circuit board plug-in element receptacle so that thereby the contact elements of the

Plug element receptacle extendable and can be inserted into the correspondingly formed contact element openings. Although such a connector assembly has many advantages, dealing with the relatively sensitive contact elements as well as its correct positioning on the circuit board can be challenging for a user.

The invention is based on the object to provide a direct plug-in device for direct plugging onto a printed circuit board, which is robust and easy to handle for a user.

To solve this problem, the invention proposes a

Direct plug device, a connection arrangement and a method with the features mentioned in the independent claims. Further developments of the invention are the subject of dependent claims.

According to one embodiment of the invention is a

Direct plug-in device for direct insertion on a printed circuit board, wherein the direct plug device, a plug-in element, the (in particular electrically insulating) receiving housing and at least one (in particular electrically conductive) received thereon pluggable (in particular spring-like) contact element (in particular a plurality of such contact elements, wherein a contact element also may be referred to as a direct plug contact), and a plug element receptacle (which may be formed in particular as a locking frame), which at least partially

(in particular laterally-circumferential) receiving the plug element is set up, has a locking device and relative to the plug element between a contact element remote state and a contact element near state (wherein in the

contact remote state a distance between the

Plug element receptacle and the at least one contact element is greater than in the contact element near state) movable

(in particular longitudinally displaceable), wherein the plug-in element

Has at least one printed circuit board side to be arranged Vorjustierstruktur, by means of placing the plug element on the circuit board with at least one corresponding Vorjustierstruktur the

Circuit board is connectable such that in the connected state, the at least one contact element to at least one correspondingly formed contact element opening (in particular a

Contact element through hole) of the circuit board is aligned, and wherein the plug receptacle over the pre-aligned on the printed circuit board plug-in element of such

contact remote state to the contact element near state is movable, that thereby the locking device and the

Vorjustierstruktur of the plug element together (or

cooperatively) are locked to the Vorjustierstruktur the circuit board.

According to another embodiment of the invention is a

Connecting arrangement provided, which is a circuit board, the

at least one Vorjustierstruktur and at least one

Having contact element opening, and having a direct plug-in device with the features described above, which is suitable for direct plugging onto the circuit board by connecting the at least one

Vorjustierstruktur of the plug element with the at least one

corresponding Vorjustierstruktur the circuit board and by means of subsequent method of the plug element receptacle relative to the plug element and the circuit board of the kontaktelementfernen

Condition is formed to the contact element near state such that thereby the locking device and the Vorjustierstruktur of the plug element are locked together on the Vorjustierstruktur the circuit board.

According to a further embodiment of the invention is a

Method for direct insertion of a direct plug device provided on a printed circuit board, wherein in the method, a plug element is provided which has a receiving housing and at least one plug-in, in particular spring-like, contact element, the plug element at least partially by a

Plug element receptacle is received, the one Has locking device and relative to the plug element between a contact element remote state and a

contact element close state is moved, the plug-in element is placed on the circuit board, whereby at least one printed circuit board-side Vorjustierstruktur of the plug element with at least one

corresponding Vorjustierstruktur the circuit board is connected such that is aligned by the connecting the at least one contact element to at least one correspondingly formed contact element opening of the circuit board (and preferably thereby simultaneously an electrically conductive contact between the at least one

Contact element and the associated at least one

Contact element opening is formed), and the

Plug element receptacle relative to the plug-in element pre-adjusted onto the printed circuit board in such a way from the contact element remote

Condition is moved to the contact element near state, characterized in that the locking device and the Vorjustierstruktur the plug-in element are locked together on the Vorjustierstruktur the circuit board. According to an exemplary embodiment, a hand-pluggable and manually detachable system is provided, with which a faulty electrical contact between at least one sensitive contact element on the one hand and a printed circuit board

on the other hand is made possible by the fact that initially at least one Vorjustierstruktur on a plug-in element with the at least one

Contact element is placed on at least one corresponding Vorjustierstruktur the circuit board. The at least one contact element can already dip into the at least one corresponding contact element opening of the printed circuit board in this Vorjustiervorgang and in this case preferably already produce an electrically conductive contact. This will be a mechanically correct attachment of the

Secured direct plug-in device on the circuit board and preferably already accomplished the electrical contact. The Vorjustiervorgang described is possible with very little effort, since the Vorjustieren still no locking attachment of Direct plug-in device on the circuit board goes along. By merely transferring an outside plug-in element receptacle from a contact element remote or circuit board remote state into a near-the-contact or near-board state, ie by

Moving the plug element receptacle in the direction of the circuit board without simultaneous movement of the plug element, wedged or anchored the at least one Vorjusti erstruktur erstruktur of the plug element due to a corresponding action of the locking device of

Plug element receptacle on the at least one Vorjustierstruktur the circuit board. Thus, a mechanically robust connection and an electrical contact can be achieved with an intuitive and simple handle, with a misalignment can be reliably excluded. The provision of a socket on the circuit board is unnecessary, since the electrical contact directly between the or

Contact elements and in the one or more contact element openings providable electrically conductive contact structure of the circuit board can be achieved. By this measure, protection of the sensitive contacts from damage is simultaneously enabled and a

reliable pre-adjustment between direct plug-in device on the one hand and printed circuit board on the other hand realized.

In addition, additional embodiments of

Direct plug device, the connection arrangement and the method described.

Generally, in the context of this application under a

Vorjustierstruktur each feature (physical structure, recess, color marking, magnetic elements, etc.) to plug-in element or

Circuit board can be understood, which promotes a corresponding arrangement to a feature of each other's Vorjustierstruktur. According to a preferred embodiment, the at least one Vorjustierstruktur of the male element at least one Vorjustierzapfen (ie a supernatant) have. The at least one

Corresponding Vorjustierstruktur the circuit board can at least one Vorjustieröffnung (for example, a through or blind hole) exhibit. In particular, the Vorjustierstruktur a pin and the corresponding Vorjustierstruktur a corresponding

Vorjustieröffnung be in the circuit board, so then a

positive engagement of the Vorjustieröffnung is made possible by the Vorjustierzapfen. It is also possible to have one

Provide Vorjustierzapfen on the circuit board and to provide the plug-in element with a Vorjustieröffnung. Preferably, however, is the provision of multiple Vorjustierzapfen on the plug-in element and corresponding Vorjustieröffnungen on the circuit board, as a correct positioning for a user is particularly intuitively specifiable and the circuit board can be made flat and mounted.

In the contact element near state, the plug element and the plug element receptacle in a first semi-stable state

(In particular, in a first latching state) be located to each other. In the contact element remote state, the plug-in element and the plug element receptacle in a second semi-stable state

(In particular, in a second latching state) be located to each other. This allows a user to be shown haptically that the

Direct plug-in device is located in a defined initial or final state, causing a faulty handling of

Direct plug-in device can be prevented. According to one embodiment, the plug-in element receptacle relative to the preassembled on the circuit board plug-in element so from the contact element remote state to the

be near the contact element state that thereby the

Locking device so mechanically acts on the Vorjustierstruktur of the plug element, that the Vorjustierstruktur of

Plug element thereby locked to the Vorjustierstruktur the circuit board. In particular, a longitudinal displacement of the

Locking device for a sideways movement of the

Vorjustierstruktur the plug element lead, so that a direction of the force applied by a user insertion force in a different direction a locking force is applied, which is applied to the Vorjustierstruktur the circuit board. A single intuitive plugging movement of the user thus also leads to a force-saving formable, but only with great effort detachable locking the

Direct plug-in device on the circuit board.

According to one embodiment, the at least one

Vorjustierstruktur of the plug element have at least one Vorjustierzapfen and the at least one corresponding Vorjustierstruktur the circuit board have at least one Vorjustieröffnung. Such Vorjustierzapfen may be sharpened end to promote easy insertion into the Vorjustieröffnung the circuit board. The

Forming the Vorjustierstrukturen the circuit board as Vorjustieröffnungen further favors a planar design of the circuit board, which is particularly advantageous combined with a socket-free configuration.

According to one embodiment, the at least one

Vorjustierzapfen have a lateral projection, which lays down after passing the Vorjustierzapfens through the circuit board and by method of the plug element receiving from the contact element remote state to the contact element near state against peeling against a back of the circuit board. By a form fit between Vorjustierzapfen and circuit board unwanted removal of the direct plug-in device can be prevented by the circuit board. Under the back of the circuit board is a major surface of the circuit board understood that in mounted on the circuit board state of the direct plug the majority of

Direct plug-in device facing away, and the ends of the Vorjustierzapfen facing or is disposed adjacent. The lateral projection may form a type of barb having an abutment surface which abuts against the back side of the circuit board when attempting to release the latch (i.e., prior to retraction of the plug receptacle relative to the plug member and into the contactor remote condition)

Pull direct plug-in device off the circuit board. According to one embodiment, the locking device may have at least one end locking pin, which dips in the male element recording from the contact element remote state to the contact element near state next to the at least one Vorjustierzapfen in the at least one Vorjustieröffnung and together with the respective Vorjustierzapfen causes the lock. In particular, a common clamping locking of the locking pin and Vorjustierzapfens done in the Vorjustieröffnung. In other words, only the pre-adjustment structure of the direct plug-in device penetrates the pre-adjustment opening of the printed circuit board before the locking and can still be removed with little effort in this state. By triggered by moving the plug element receptacle relative to the plug element locking process, the respective locking pin slides next to the respective

Vorjustierzapfen in the Vorjustieröffnung the circuit board and causes two things: on the one hand, the locking pin presses the Vorjustierzapfen resiliently against the wall of the Vorjustieröffnung and can thereby lock or jam, for example, the lateral projection behind the circuit board. It can also be a force or frictional engagement between the Vorjustierzapfen and the wall of the Vorjustieröffnung be effected or the Vorjustierzapfen be wedged or jammed in the Vorjustieröffnung. On the other hand, the locking pin fills at least partially a cavity of the pre-adjusting opening remaining even after insertion of the prealigning pin and is thereby wedged or clamped together with the pre-adjusting pin itself on the wall of the pre-adjusting opening. A peeling off the

Direct plug-in device of the circuit board is in this mode only with an extremely high effort (or even non-destructive no longer possible). Only retraction of the plug element receptacle into the circuit board remote or contact hole remote state also pulls the locking pin out of the Vorjustieröffnung and makes the above two wedging effects simultaneously and reversibly retroactively. According to one embodiment, the at least one Contact element with respect to the receiving housing on the circuit board side (in particular in the insertion direction immovable and / or perpendicular to the insertion direction spring-like) survive. A mechanism which realizes a lead in the contact elements in the receiving housing or a lead out of the contact elements of the receiving housing, is thereby unnecessary. In other words, the contact elements are statically beyond the receiving housing in any operating state of the direct plug device. The at least one contact element can preferably be moved only in a direction perpendicular to the insertion resiliently, so that by the spring action of

Contact element, the fastening effect of the direct plug on the circuit board in the inserted state is further enhanced and a continuous electrically conductive connection between the contact element and contact element opening is further promoted. If the

Contact elements with respect to the receiving housing protrude immovably, serves a preferably flat end face of the

Receiving housing, from which protrude the contact elements, as a stop or stop surface when pre-adjusting insertion of

Direct plug-in device in the printed circuit board with retracted

Plug element receptacle.

According to one embodiment, the at least one

Vorjustierstruktur of the plug-in element, the at least one

Protect contact element protectively. If the particular as

Vorjustierzapfen trained Vorjustierstruktur of the plug element with respect to the receiving housing protrudes further than the

Contact elements, can be sensitive electrically conductive

Contact elements are protected by the Vorjustierzapfen from unwanted mechanical damage by impact with the environment. This is especially true when a plurality of

Vorjustierzapfen along a circumference of the contact elements are arranged and the contact elements thus all in front of a

Protect mechanical damage. For example, four

Vorjustierzapfen be attached to the four corners of a rectangular, matrix-like arrangement of contact elements to protect the To ensure contact elements against mechanical interference from any direction.

According to one embodiment, the at least one

Vorjustierstruktur of the plug element to be resilient (in particular be formed of a self-resilient material or be resiliently mounted) that by sliding the plug element from the contact element remote state to the contact element near state, the locking device on the resilient Vorjustierstruktur of the plug element slides and this perpendicular or at least angled to the direction of travel against the Vorjustierstruktur the

PCB expands. Thus, the method of the

Locking device along a longitudinal axis

(In particular in the plugging direction) have a mechanical action on slightly obliquely arranged Vorjustierzapfen the direct plug device result, so that they are pressed laterally elastic, which can make at least a contribution to the lock.

According to one embodiment, the plug-in element along its circumference may comprise a plurality of Vorjustierstrukturen by the method of the plug element receiving from the contact element remote state to the contact element near state of the

Locking device is locked to a plurality of Vorjustierstrukturen the circuit board. By Vorjustierstrukturen are particularly all around attached to the Direktsteckvorrichtung, symmetrical and force peaks avoiding handling of

Direct plug device can be achieved. Especially with the provision of two and in particular more than two Vorjustierstrukturen can

erroneous insertion of the direct plug-in device in the circuit board are mechanically impossible, as this can be excluded by a fault-rugged form coding.

According to one exemplary embodiment, the pre-adjustment structures of the plug-in element and the locking device can be adapted to one another such that different pre-adjustment structures of the Plug element acting locking forces in different directions, in particular in pairs, for example, opposite directions, act. For example, can be effected by the forward sliding of the male element receptacle relative to the plug element parallel forward displacement of different locking pins and thereby simultaneously spreading outside Vorjustierstrukturen of the male element are effected on the outside, resulting in a leading to an efficient locking force introduction result. Also, this can provide protection against unwanted removal of the direct plug-in device from the circuit board in different

Directions are ensured.

According to one embodiment, the plug-in element may have a (for example frame-like) Vorjustiergehäuse which is resiliently disposed between the receiving housing and the plug receptacle and on which the at least one Vorju bull structure of the plug attached, for example, integrally formed and / or einstoffig. Both the Vorjustiergehäuse and the

Plug element receptacle can be arranged like a frame around the, for example, closed on all sides receiving housing.

According to one embodiment, the Vorjustiergehäuse by means of at least one resilient bridge element (in particular in one piece, more particularly einstoffig) may be connected to the receiving housing. The Vorjustiergehäuse and the receiving housing can thus be mechanically weakly coupled to each other, for example by means of one or more resilient connecting elements, such as plastic webs. This allows one for the plug and

Locking process advantageous compensation movement between the at least one locking structure of the plug element and the at least one contact element. For example, both the receiving housing and the Vorjustiergehäuse be made in injection molding and / or plastic material and be assembled into a common component. This allows a cost-effective

Production and fault-bust operation of the direct plug-in device. According to one embodiment, it is possible that the

Recording housing consists of two, three or more sub-housings that can be mechanically mated together so that remain between hidden sub-housings receiving spaces for the contact elements. As a result, the contact elements (for example with connected cable connections or the like) can be inserted into the receiving spaces and subsequently by means of

Mating the associated sub-housing are clamped to be mounted on the receiving housing. Associated sub-housings may, for example, have mutually inverse rectangular profiles, between which an easily formed and reliable connector can be made. At two edges arranged part of the housing

Receiving housing components may be integrally formed Vorjustiergehäuses and resiliently connected by means of the bridge elements. With one or more optional central part housings between the two peripheral part housings then the number of desired contact elements can be scaled arbitrarily. According to one embodiment, the Vorjustiergehäuse

at least one guide groove (in particular, in each case positioned next to an associated Vorjustierstruktur), along which the locking device of the plug element receiver is guided guided by applying a locking force to the at least one Vorjustierstruktur the plug element. Through such guide grooves, an interaction between the plug element and plug element receptacle can be precisely defined and incorrect use of

Direct plug-in device are almost excluded. Along the

Guide groove can slide guide rails of the locking device, which guide rails rigid with end-side

Locking pin of the locking device can be coupled and thus the movement of the guide rails along the

Follow guide grooves. According to one embodiment, the plug element receptacle relative to the plug-in element preassembled on the printed circuit board in such a way from the contact element remote state to the

be near the contact element state that thereby the

Locking device the Vorjustierstruktur of the plug-in element on the Vorjustierstruktur the printed circuit board positively locked and / or non-positively and / or frictionally locked. As a result, a strong holding force can be applied, the only by retracting the

Plug element receptacle relative to the plug element and the

Printed circuit board is removed again, which then allows a low-force removal of the direct plug-in device of the circuit board.

According to one embodiment, the plug element and the plug element receptacle can thus be designed such that starting from a state in which the locking device the

Vorjustierstruktur of the plug element locked to the Vorjustierstruktur the circuit board, the plug element receptacle of the

contact near state to the contact element remote state is retracted so that thereby the lock is released and then the plug-in element of the circuit board is separated kraftarm. Consequently, both a low-force mounting of the direct plug-in device on the circuit board and a low-power removal of the

Direct plug-in device of the circuit board allows, on the other hand, however, in the inserted and locked state, a peeling off the

Direct plug-in device of the circuit board with normal force impossible.

According to one exemplary embodiment, the plug-in element and the plug-in element receptacle can be adapted to one another such that one (in particular interrupted only by the contact elements and otherwise substantially coherent)

PCB contact surface of the receiving housing and a (in particular annular and the PCB touch surface of the receiving housing surrounding) PCB contact surface of the plug receptacle in the contact element near state are coplanar to each other. Thus lie in the contact element near state, that is in pre-aligned and locked state of the direct plug-in device, both

PCB contact surfaces are contact-based on a flat counter surface of the circuit board and thus form a mechanically stable and defined configuration. In the contact element remote state (for example, in a pre-adjusted, but not yet locked state), however, the two PCB touch surfaces can be offset from each other in parallel. A correct Vorjustierzustand (but still without

Locking) can thus be visually controlled by a user that in this the receiving housing with his

PCB contact surface is applied directly to the circuit board. A correct lock state can be visually effected by a user

be controlled that in this also the plug element receptacle is applied directly to the circuit board. According to one embodiment, the plug-in element receptacle can be formed from an electrically insulating material, in particular from plastic. Also the plug element can with the exception of

preferably be made of metal contact elements made of plastic. The plug element receptacle and components of receiving housing and optional locking housing can all be made by injection molding. The electrically conductive

Contact elements can be inside the receptacle of the

Plug element are electrically coupled with cables or the like, by means of which the circuit board can be coupled to an electronic periphery. The contact elements themselves can be formed from a stamped and bent sheet metal plate.

According to one embodiment, the printed circuit board may be socket-free at least in a region in which the attachment between the direct plug-in device and the printed circuit board takes place. This allows a flat and compact design and installation.

In the following, exemplary embodiments of the invention will be described with reference to the figures.

FIG. 1 shows a three-dimensional view of a direct plug-in device 108 according to an exemplary embodiment for plug-free direct plugging onto a printed circuit board 302 (see FIG. 3). In the operating state shown in FIG. 1, a frame-shaped plug-element receptacle 120 of the direct plug-in device 108 is located opposite a box-shaped plug-in element 110 in a contact element-remote state, as indicated by reference numeral 104. In other words, the plug element receptacle 120 is opposite to the

Plug element 110 up to a rear locking position so

shifted back that a maximum distance D between a

Printed circuit board contact surface 175 of the plug element receptacle 120 and a circuit board contact surface 177 of the plug element 110 is formed, wherein contact elements 106 extend out of the circuit board contact surface 177 of the plug element 110. The distance D may be, for example, 1 cm. In the state shown in FIG. 1, the direct plug-in device 108 is ready to be plugged into the printed circuit board 302 for the pre-adjusted state. The direct plug-in device 108 has the plug-in element 110, which has a central receiving housing 114 made of plastic and a matrix-like arrangement of here nine electrically conductive spring-like

Contact elements 106 (according to the embodiment shown designed as a double-fork spring structure). The contact elements 106 are opposite the receiving housing 114 on the circuit board side and are provided immovably relative to the receiving housing 114 in the insertion direction 173. Each of the contact elements 106 is electrically conductively coupled to a respective one of cables 130 (not shown) inside the receptacle housing 114 for transmitting an electrical signal between a respective cable 130 and a respective contact on the circuit board 302. The plug-in element 110 has a Vorjustiergehäuse 118, which is resiliently arranged between the receiving housing 114 and the plug-element receptacle 120 and on which the Vorjustierstruktur 112 of

Plug element 110 is formed. The Vorjustiergehäuse 118 is externally connected to the receiving housing 114 by means of resilient bridge elements.

The plug-in element receptacle 120 of the direct plug-in device 108 is designed for the partial, circumferentially surrounding receiving of the plug-in element 110. The plug element receptacle 120 has a

Locking device 102 in the form of four mounted in four corner areas locking pins or locking pin. The entire plug element receptacle 120 together with the rigid

attached latching device 102 is relative to the

Plug element 110 between the contact element remote state 104 (see Figure 1, D = l cm) and a contact element near state 200 (see Figure 2, distance D = 0) movable, wherein in the

contact near state 200, the PCB contact surface 175 of the plug element receptacle 120 and the PCB contact surface 177 of the plug 110 with each other in a common

PCB touch level are aligned or aligned. To transfer the Direct plug-in device 108 between the two operating state shown in Figure 1 and Figure 2, a user can engage with gripping pieces 140 which are integrally formed on an outer side of the plug element receptacle 120.

The plug-in element 110 has in the illustrated embodiment four, on the mounting board side to be arranged and trained as Vorjustierzapfen Vorjustierstrukturen 112, which are attached to four corners of an imaginary rectangle and connected by placing the plug 110 on the circuit board 302 with corresponding Vorjustierstrukturen 306 of the circuit board 302 are. Since in the illustrated embodiment, the Vorjustierstrukturen 306 of

Printed circuit board 302 are formed as Vorjustieröffnungen (see Figure 3), immerge the Vorjustierzapfen in the pre-adjustment in this

Vorjustieröffnungen a, but without first being fixed with a firm fastening force in this. However, the formed temporary connection is configured so that in this state, the contact elements 106 formed correctly to correspond

Contact element openings 304 of the circuit board 302 (see Figure 3) are aligned. The contact elements 106 protrude less far beyond the printed circuit board contacting surface 177 of the receiving housing 114 in the direction of the printed circuit board 302 than the Vorjustierstrukturen 112. Die

Vorjustierstrukturen 112 of the plug element 110 so project beyond the contact elements 106 in the direction of the circuit board 302 protective. Therefore, the contact elements 106 dive only after immersing the

Vorjustierstrukturen 112 in the Vorjustierstrukturen 306, and thus only at the completion of Vorjustierens, in the contact element openings 304 a. Since the contact elements 106 are laterally resilient, they express themselves against the metallized walls of the

Contact element openings 304 of the printed circuit board 302 and thereby achieve a reliable and uninterrupted electrical coupling of the contact elements 106 with a corresponding wiring of the printed circuit board 302. This allows the mechanical pre-adjustment and the electrical contact between the direct plug device 108 and the circuit board 302 simultaneously and by a common hand movement be accomplished without even a vibration-resistant and reliable fastening force between the direct plug device 108 and the circuit board 302 would be applied. The plug-in element receptacle 120 is subsequently movable relative to the plug-in element 110 pre-adjusted onto the printed circuit board 302 from the contact-element-free state 104 to the contact-element-near state 200, thereby locking the latching device 102 and the pre-alignment structure 112 of the plug-in element 110 on the

Vorjustierstruktur 306 of the circuit board 302 are locked. In other words, after the pre-adjustment and the electrical contact, a user merely needs to move the plug-in receptacle 120 against the plug 110 and the circuit board 302 by the distance D until an annular abutment surface in the form of the

Printed circuit board contact surface 175 of the plug element receptacle 120 abuts the planar printed circuit board 302 at this point.

As a result of this mere displacement operation (which can be accompanied by engagement between the plug element 110 and the plug element receptacle 120 simultaneously with the abutment of the printed circuit board contact surface 175 against the printed circuit board 302), as will be described in detail below, a clamping fastening force is created between the direct plug device 108 and the printed circuit board 302, which ones for mounting

Each of the Vorjustierzapfen the Vorjustiereinrichtung 112 has a lateral projection 116, which after passing through the associated Vorjustierzapfens by the circuit board 302 and by methods of

Plug element receptacle 120 from the contact element remote state 104 to the contact element near state 200 lockingly clamped against a back side of the circuit board 302. This is done by the im

Further described configuration of the locking device 102 allows: The locking device 102 is in the form of four end locking pins or locking pins carried out, each of which in method of the plug element receptacle 120 from the contact element remote state 104 to the contact element near

State 200 next to and with an associated one of the four Vorjustierzapfen the Vorjustiereinrichtung 112 dips into the associated Vorjustieröffnung 306 and together with the respective Vorjustierzapfen the

Lock causes. This results in a common

Locking lock of the locking pin of the

Locking device 102 and the Vorjustierzapfens the

Vorjustiereinrichtung 112 in the Vorjustieröffnung 306. The

Vorjustiergehäuse 118 has guide grooves 122 along which the locking pins or locking pins of

Locking device 102 of the plug-in element receptacle 120 can be moved guided by exerting a locking force on the associated Vorjustierzapfen the Vorjustierstruktur 112 of the plug element 110. The locking pins are made by advancing the

Plug element receptacle 120 by the distance D in the direction of

Printed circuit board 302 moves. At this time are the

Pre-alignment pin already with play in the Vorjustieröffnungen. The

Locking pin fill as a result of the forward movement of a still free space in the Vorjustieröffnungen and thus lie next to the Vorjustierzapfen in the Vorjustieröffnungen. During this

Forward movement, the locking pins laterally bias the pre-alignment pins against the wall, thereby locking the pre-alignment pins in the pre-alignment holes. At the same time in a synergistic way, the locking pin against the wall in the press

Vorjustieröffnungen, since the diameter of the locking pin plus Vorjustierzapfen is slightly larger than the diameter of the

Vorjustieröffnungen. The Vorjustierstruktur 112 of the plug-in element 110 is thus designed so resilient that by methods of

Plug element receptacle 120 from the contact element remote state 104 to the contact element near state 200, the locking device 102 slides on the resilient Vorjustierstruktur 112 of the plug 110 and this perpendicular to the direction against the Vorjustierstruktur 306 of the circuit board 302 suppressed. The pre-adjustment structure 112 of the plug element 110 and the locking device 102 are adapted to one another in such a way that in different

Vorjustierstrukturen 306 locking forces in different

Interact with directions. In the embodiment shown, the Vorjustierzapfen are all spread outwards by the method of the locking pins.

The plug element 110 and the plug element receptacle 120 are designed such that, starting from the state in which the

Locking device 102, the Vorjustierstruktur 112 of

Plug element 110 is locked to the Vorjustierstruktur 306 of the circuit board 302, the plug element receptacle 120 of the

Contact near state 200 to remove the contact element

State 104 can be moved back in such a way that the lock is released and then the plug-in element 110 can be separated from the printed circuit board 302 with little force. The attachment or

Locking mechanism is thus formed reversible.
