Abstract
Plug connector (1) comprising at least two parts, for example a housing (3) and a contact carrier or a multipart housing (3) in which the contact carrier with contacts is arranged, wherein the at least two parts, preferably exactly the two parts, are combined together and a connection to one another is produced by means of at least one pin (5) which passes through the two parts in each case at least in part.
Description
Technical Field
The invention relates to a plug connector with at least one safety pin. The invention relates more particularly to a plug connector according to the features of the preamble of claim 1, comprising at least two parts (e.g. a housing and a contact carrier) or a multipart housing in which the contact carrier with the contacts is arranged.
Background
A plug connector is known from the prior art, which comprises at least two parts (for example a housing and a contact carrier) or a multipart housing in which the contact carrier with the contacts is arranged.
It is known to connect the at least two parts by fixedly connecting the at least two parts to each other in their position by means of a locking device, for example a locking hook on one part of the plug connector and a corresponding recess on the other part of the plug connector. It is necessary here to manufacture the two parts very precisely (for example in a plastic injection molding process) so that the locking means which interact together fix the two parts in their set position in position relative to one another. However, a very precise manufacturing process is required here, which is costly. Nevertheless, component tolerances/tolerance chains with reference geometries still exist, which may lead to deviations from the set position.
Furthermore, it is also known to bond the at least two components to each other. In this case, the components can be fastened to one another in their set position and connected to one another after the adhesive has cured. However, this solution does not have long-term stability, since there is a risk that the adhesive will loosen, for example due to vibrations. In addition, these adhesives release gases and affect contact safety and their surroundings.
Disclosure of Invention
The object of the invention is therefore to simplify the connection of at least two parts of a plug connector while maintaining the exact position of the at least two parts relative to one another.
This object is achieved by the features of claim 1.
According to the invention, it is provided that: the at least two components, preferably exactly two components, are combined together and a connection to each other is created by means of at least one pin (also called a pin) which passes at least partially through the two components, respectively. This has the advantage that the at least two components can be combined together and subsequently connected together independently of their respective tolerances, without significant effort for following the tolerances or for further compensation of the tolerances.
In the simplest case, the at least two parts of the plug connector are parts of their housing (for example two parts forming the housing, preferably exactly two parts) or a housing part, which are connected to the contact carrier of the plug connector by means of the at least one pin. The at least one pin ensures that the at least two parts are connected to each other without play and with compensating tolerances.
In addition to this simplest case, other applications are conceivable in which at least two parts, preferably exactly two parts, of the plug connector are connected to one another by means of a pin.
Thus, at least two parts of the plug connector are permanently positioned and/or connected to each other in their position by means of the pin according to the invention. If the plug connector is to have three parts, these are positioned and/or connected to one another by means of pins. If the plug connector has four parts, these are positioned and/or connected to each other and so on. When the expression "two parts" is used in the description and/or in the patent claims, this expression means that the two parts of the plug connector or also more than two parts, as described above, are positioned and/or connected to each other.
In a further development of the invention, provision is made for: the pin is made of a metallic material. This has the advantage that such a pin is very stable and can pass through components of the plug connector, for example a shielding cage, which are likewise made of metallic material. The same applies to particularly hard materials made of plastics or other comparable materials. On the other hand, the advantage of using metallic materials is: if necessary, an electrical connection can be established between the at least two components of the plug connector. For such an electrical connection, use of shielding means is for example considered.
In a further development of the invention, the pin is made of a non-conductive material, for example of a correspondingly rigid plastic material, which is suitable and determines the at least two parts to be connected together for passing through the plug connector. Such pins made of plastic can be produced in large quantities, in particular automatically, and can also be used, in particular automatically, when connecting the at least two parts of the plug connector to one another. Furthermore, the advantage of a pin made of plastic is that it acts electrically insulated. This is particularly important when the at least two components (or more than two components) should remain electrically isolated from each other and should therefore not be electrically connected to each other.
In a further development of the invention, provision is made for: the at least two components have means corresponding to each other which, when the components are combined together, cause the at least two components to be pre-positioned and/or pre-fixed with respect to each other. As means for the pre-positioning, for example, a tongue and groove corresponding to each other are considered, as are a groove in one part and a projection in the other part of the plug connector. Devices of this type only achieve a predetermined position, so that the two components are permanently and positionally correctly connected to one another by means of a pin (or pins) according to the invention. As means for pre-fixing, for example, a recessed fastening (HINTERSCHNITT) in one component and a hook, in particular a latching hook, in the other component are considered, so that when the two components are combined together, a temporary fixing of the two components to one another is already achieved. In both cases, i.e. in the case of pre-positioning and also in the case of pre-fixing, the respective means can be designed such that the two parts (or more than two parts) can still be moved slightly relative to each other and the final arrangement and positioning is only accomplished with the at least one pin according to the invention.
In a further development of the invention, the pin has a sharpened portion at one end of the pin, with which the pin starts to pass at least partially through the two parts (or more than two parts), respectively. By means of the pointed portion, the at least two parts of the plug connector can be penetrated more easily. The tip portion considers not only pins made of conductive material but also pins made of non-conductive material.
Additionally or alternatively thereto, the pin has an expansion at one end of the pin, the end with expansion being opposite the end with which the pin passes at least partially through the two parts, respectively. When the pin passes completely and expediently through the at least two components and connects them to one another, the pin rests against one component of the plug connector, more precisely against its surface, by means of the expansion, which can be formed, for example, as a cross piece or as a thickening. The expansion can also be detected, for example, optically or automatically, in order to ensure that the pin has completely passed through the at least two components and has reached its prescribed final position.
Additionally or alternatively thereto, the pin has means (also referred to as a compression) between its two ends for locking in at least one of the two parts, preferably in both parts. The means for locking may be, for example, a protruding boss, tab, hook or similar structure, which protrudes from the surface of the elongate pin in the course between its two ends. The cross section of such a means for locking may be angular or arcuate, for example.
A particularly preferred application of the at least one pin for connecting at least two components of a plug connector is in plug connectors for high voltage technology, in particular in electric vehicles. At voltages of more than 100V, for example more than 400V, 800V or higher, the contact of the plug connector and its cable (the contact being provided on the cable) need to be protected against radiation from the contact or from the cable into the external environment. This is achieved at the cable by means of a corresponding shielding device, for example a shielding mesh. At the plug connector, for the shielding, a shielding cage (component of the plug connector) is provided around the contact but is electrically isolated from and not in contact with the contact, with which the radiation is blocked. At the same time, the shielding cage must be connected to other components of the plug connector (for example to a component of the multipart housing or to the one-piece housing itself). For this purpose, the shielding cage is combined with the housing or its housing parts, oriented in its position with respect to one another and the at least one pin is pressed at least partially through the two parts to be connected to one another, in order to permanently connect the parts to one another without play and with compensation for any tolerances. Preferably, the at least one pin passes completely through the housing and completely through the shielding cage. In high pressure applications, the at least one pin is made of a metallic material. This has the advantage that the pin has the required stability for penetration. On the other hand, a void is created when the pin penetrates the shielding cage. If the pin is made of a non-conductive material, it will cause the void to radiate there. This is effectively prevented by means of pins made of metallic material.
Drawings
A specific embodiment is shown in fig. 1-6.
Detailed Description
The electrical plug connector 1 is arranged on a single-or multi-conductor cable 2. The plug connector 1 has a one-part housing 3 in which at least a shielding cage 4 made of a metallic material is arranged. The housing 3 is one component of the plug connector 1 and the shielding cage 4 is a second component, which should be combined together and fixed to each other. The fastening is effected by at least one pin 5, preferably a pin made of metallic material. At least one contact of the plug connector 1 is provided in the shielding cage 4, which contact is arranged at one end of the electrical conductor 6 of the cable 2 and is electrically connected thereto.
The different views of this embodiment are shown in different detail views in fig. 1 to 6 for applications in high-pressure technology. As can be seen in particular in fig. 4 and 5, the plug connector 1 has two contact portions, around which a respective shielding cage 4 is provided. For this purpose, there are also two pins 5 (as shown in fig. 1 and 2), wherein each pin 5 connects the housing 3 with the respective shielding cage 4 without play and with compensating tolerances. Alternatively, it is of course possible to surround all contacts of the plug connector 1 with a single shielding cage 4 and to connect the shielding cage with the housing 3 using one pin 5 or, if appropriate, also two, three or more (metal) pins 5.
