Definitions
- the invention relates to an electrical plug-in device with a front housing, to which components provided for receiving electrical contact elements (pins, sockets) are connected.
- Electrical plug devices such as plugs or sockets or couplings for power current according to DIN VDE 0623, EN 60309-2 (“CEE plug devices”) or according to IEC 62196 (“E-car charging plug devices”) contain an access side on which a complementary trained
- Plug device (coupling or plug) can be inserted.
- the access side typically has a front housing, which closes off the plug device in this area from the outside and is electrically insulated, an insert (as a separately manufactured component) being arranged in the front housing, which contains the actual metallic contact elements (pins for a plug and sockets for a socket ) and their electrical connection to an electrical supply line.
- an insert as a separately manufactured component
- Screwed front housing which however requires a relatively complex assembly.
- the basic structure of a plug-in device according to the invention which, as explained at the beginning, can in particular be designed as a plug or as a socket / coupling, comprises the following components:
- Insert module has second latching elements, which latch when inserting the insert module into the front housing with its first latching elements and thus ensure a coupling, preferably for a firm fixation of the insert module in the front housing. Furthermore, the second latching elements, which latch when inserting the insert module into the front housing with its first latching elements and thus ensure a coupling, preferably for a firm fixation of the insert module in the front housing. Furthermore, the second latching elements, which latch when inserting the insert module into the front housing with its first latching elements and thus ensure a coupling, preferably for a firm fixation of the insert module in the front housing. Furthermore, the second latching elements, which latch when inserting the insert module into the front housing with its first latching elements and thus ensure a coupling, preferably for a firm fixation of the insert module in the front housing. Furthermore, the second latching elements, which latch when inserting the insert module into the front housing with its first latching elements and thus ensure a coupling, preferably for a firm fixation of the insert module in the front housing
- a holding plate which is set up for receiving electrical contact elements (typically pins or sockets) and which has fourth latching elements which, when the holding plate is coupled to the
- first, second, third or fourth latching elements are used in the plural, this relates to the typical case and is not intended to exclude the possibility that in certain embodiments only a single first, second, third and / or fourth latching element is provided ,
- the electrical contact elements typically have a longitudinal extent, which determine the plugging direction in which the plug device can be joined together with a complementary plug device during the plugging process.
- This longitudinal extension or plug-in direction is used in the following as a reference axis for terms such as "axial”, “radial” or “circumferential direction”.
- the front housing is typically arranged on the access side of the plug device, that is, where the plug-in process takes place. In terms of the three-dimensional shape, it is generally tubular in principle with a tube axis which corresponds to the plug-in direction mentioned above.
- the term “collar” is intended to refer to only one area of the front housing in the broadest sense.
- the collar is a terminal area of the front housing, particularly at the "proximal" end of the front housing facing away from the access side.
- the collar has an external thread on its outside, via which the front housing with a further, rear housing part
- connection between the front housing and the insert module or between the insert module and the holding plate preferably takes place exclusively through the interaction of the first and second latching elements or the third and fourth latching elements, without the need for further aids such as screws.
- the axial extents of the second latching elements and third latching elements overlap on a plug-in device with the basic structure described above
- Insert module (in whole or in part), the "axial" direction being defined by the direction of insertion as explained. Since the second and third locking elements of the insert module are typically arranged at the level of the assigned first and fourth locking elements, the axial overlap between They usually also have an additional axial overlap with the first and / or fourth locking elements.
- a plug-in device is preferably designed in accordance with both aspects, i.e. that the second and third locking elements overlap axially and that in the assembled state the first, second, third and fourth locking elements are all arranged in the collar.
- Plug devices according to the first and / or second aspect of the invention have the advantage that they can be easily installed using latching elements, preferably solely by latching processes
- At least one of the third locking elements can be designed as a U-shaped bracket, which is at least one of the second
- U-shaped should be understood in a general sense and should also include, for example, arch shapes or C shapes.
- the outer legs of the U-shape of the bracket are axial, i.e. in the direction of insertion
- Insert module designed as such a bracket, each surrounding at least a second locking element.
- brackets in the circumferential direction Locking elements there are at least two brackets in the circumferential direction Locking elements, between which at least one of the second locking elements is arranged.
- All third locking elements of the insert module are preferably designed as brackets, and the associated second locking elements are arranged alternately within a bracket or between two brackets.
- Electrical connectors are often manufactured with different electrical assignments of the contact elements (e.g. as an outer conductor, neutral conductor, or protective conductor). In order to use as few different (injection molding)
- the front housing and the insert module are preferably relative at least two different angles of rotation
- Rotation angles also called time positions, are plugged together in order to implement a corresponding number of variants of the finished plug device.
- the front housing and the rear housing are identical to one embodiment.
- Insert module set up to be assembled by plugging in from the side of the collar.
- the insert module is therefore not inserted from the front (distal) access side of the front housing, but on the rear (proximal) collar side, so that the back of the insert module
- Insert module on which the holding plate is to be mounted does not have to be guided through the front housing from the access side (which would normally not be possible due to space constraints). This has the advantage that the holding plate can be preassembled on the insert module and that the
- Insert module with preassembled holding plate can be inserted into the front housing from the collar side. This possibility of pre-assembly considerably simplifies the production process.
- first, second, third and / or fourth locking elements could be present.
- two or more of the first, second, third and / or fourth locking elements are provided for reasons of stability, these
- Circumference distribution i.e. at equal angular distances.
- At least one of the first locking elements, second locking elements, third locking elements and / or fourth locking elements can be designed as a nose-shaped (ramp-shaped) projection.
- a projection has a slope ("bridge of the nose"), along which a
- complementary locking element can slide when joining, it after passing the tip of the nose and with the regression of an elastic
- Deformation protrudes and thus blocks the backward movement.
- the essential components in the plug-in device according to the invention can each be produced and sold as independent products.
- the invention therefore also relates to a kit which contains at least one of the three components (front housing, insert module and / or holding plate) for a plug device according to one of the above-described embodiments.
- Holding plate belong, in which case it usually also contains the associated contact elements (pins, sockets).
- Figure 1 is an overall perspective view of an inventive
- FIG. 1 shows the plug after detaching the rear housing part from
- Front housing in which an insert module with a holding plate is arranged; 3 shows the insert module with the holding plate before insertion into the front housing;
- Figure 4 shows the insert module and the holding plate and pins in
- Figure 5 shows the view of Figure 4 from a perspective from the front
- FIG. 6 shows an enlarged view of the insert module from a perspective from the front
- Figure 7 is an overall perspective view of an inventive
- Figure 8 shows the insert module, the holding plate and the sockets of the coupling in a separate state in an exploded view
- Figure 9 shows the exploded view of Figure 8 together with the front housing from the rear.
- a plug device designed as a plug 100 according to the present invention is shown in increasing degrees of disassembly or in reverse order of assembly.
- Figure 1 first shows the fully assembled plug device 100 in a perspective view obliquely from the front, i.e. with a view of the access page.
- the plug pins ST can be seen, which are arranged for protection and insulation in a tubular front housing 1 10 (hereinafter also generally provided with the reference symbol "FG").
- the longitudinal axis of the plug pins ST defines the plugging direction of the plug device and is used in the following as reference axis X.
- the front housing FG and a rear housing part 120 (“hood”) are connected to one another by a screw connection
- This screw connection is made via an external thread, which in the Area of a (ie proximal) collar 1 12 of the front housing facing away from the access side is provided.
- Figure 3 shows the front housing FG separately, i.e. before inserting one
- Insert module 140 (EB) and a holding plate 130 (“HP), which are already connected to one another in the course of a preassembly and thereby the
- first locking elements 1 1 1 (“RET ') can be seen in the form of lugs, which are evenly distributed over the circumference. These first locking elements RE1 have a slope, which is seen along the axis X to the access side of the front housing FG runs radially inwards.
- second nose-shaped latching elements 142 (“RE2”) are arranged pointing radially outward, with respect to the axial direction X one of the first latching elements RE1
- the second latching elements RE2 slide inward with their nose bridge along the nose bridge of the first latching elements RE1 with elastic radial deformation.
- the tips of the noses pass each other, so that the latching elements RE1, RE2 latch together with each other under elastic reshaping and an axial withdrawal of the insert module EB from the front housing FG is prevented.
- the front housing and insert module are thus firmly connected.
- FIG. 4 shows an exploded view of the insert module EB separated from the holding plate HP and also the connector pins ST with the associated ones
- Screws 133 separately from the holding plate HP.
- the connector pins ST are accommodated on the holding plate HP in elevations 132 which extend axially from the body 131 of the holding plate. Electrical connection lines (not shown) can be connected to the ST plug pins by means of the screws 133.
- FIG. 5 shows a view obliquely from the front.
- FIG. 6 shows the insert module EB from an oblique front in an enlarged view.
- the nose-shaped second locking elements RE2 can be seen particularly well, of which in the illustrated
- Embodiment 12 pieces are arranged evenly distributed over the circumference, with their lugs extending radially outwards.
- the second locking elements RE2 are elastic in the radial direction, so that they can move somewhat inwards during the locking process during assembly.
- U-shaped brackets can be seen, which form the third latching elements RE3. 6 of these are evenly distributed around the outside of the insert module EB.
- Each bracket RE3 surrounds one of the second latching elements RE2.
- a further one of the second latching elements RE2 is arranged between two brackets RE3.
- the cross-connecting web of the U-shaped bracket RE3 is used for latching with the fourth latching elements RE4, which are arranged in a nose-like manner pointing radially outward along the outer circumference of the holding plate HP (FIG. 4).
- the brackets RE3 typically move elastically somewhat radially outward.
- the second locking elements RE2 and the third locking elements RE3 are arranged axially overlapping on the insert module EB. This means that each of these locking elements has a certain axial extension, the axial extensions e2 of the second locking elements RE2 being aligned with the axial ones
- Extends e3 of the third latching elements RE3 at least partially overlap (FIG. 6). In this way, a particularly compact construction is achieved in the axial direction. This can be used, for example, to design shorter contact elements ST and thus save material (e.g. brass).
- a second characteristic of the construction described is that the first, second, third and fourth locking elements RE1, RE2, RE3, RE4 in the assembled state all (axially) in the region of the collar 1 12 of the
- Front housing FG are housed. This is in the example shown This is particularly important for the third, U-shaped locking elements RE3, since the surrounding collar 1 12 prevents their radial movement outwards, so that after they have been joined together, they can no longer be detached from the fourth locking elements RE4 of the holding plate HP.
- the insert module EB is inserted into the front housing FG only from the side of the collar 1 12 (facing away from the access side). On the one hand, this simplifies assembly, since it is not necessary to turn the front housing over. On the other hand, it allows the pre-assembly of insert module EB and holding plate HP as shown in FIG. 3.
- FIGS. 7-9 show the exemplary structure of a plug-in device in the form of a coupling 200, components of the same type as in the plug 100 being provided with reference numbers increased by 100 or with the same reference letters.
- the clutch 200 in turn consists of a rear housing part 220, which is connected to a front front housing 210 / FG via an external thread
- Collar 212 of the front housing is screwed.
- An insert module 240 / EB is also attached to the front housing FG. This can be done with a
- Holding plate 230 / HP are locked, the holding plate carrying the metallic bushes BU as contact elements.
- connection between the front housing FG and insert module EB is made by latching between the nose-shaped first latching elements 21 1 / RE1 on the
- connection between insert module EB and holding plate HP is made by latching bow-shaped third latching elements 243 / RE3 on
