Other advantageous further developments and configurations of the plug-in connector according to the invention, having at least one side element, are apparent from the description that follows. One embodiment of the plug-in connector according to the invention is illustrated in the drawing in which:
It is assumed for purposes of the illustrated embodiment that the plug-in connector 10 is implemented as a trapezoid plug-in connector, also known as D-Sub plug-in connector. That type of plug is specified in more detail in DIN 41652 and IEC 807-3, respectively. Such a plug-in connector 10 usually is employed for making plug-in connections in the context of standardized interfaces, especially computer interfaces.
The side element 12 comprises at least one locating element 20 which may be described as a clip, for example. In the illustrated embodiment, the locating element, being implemented as a clip, is composed of two clip arms 21, 22. An especially simple configuration is obtained when the locating element 20, or the clip arms 21, 22, respectively, are worked from the side element 12 by punching and bending.
In the illustrated embodiment, two locating elements 20 are provided on one side element 12 in staggered arrangement, relative to the plug-in connector 23. The plug-in direction 23 likewise corresponds in this case to the longitudinal direction of the mounting element 13.
The side element 12 is provided, if necessary, with a solder terminal preferably implemented as SMD solder terminal. According to one embodiment, the solder terminal 30 comprises at least one recess 31 that can be entered by the soldering flux. The solder terminal 30 is provided especially in cases where the plug-in connector 10 according to the invention is intended for being soldered to a board 32.
Preferably, the side element 12 comprises at least one contact spring 40 that is positioned in a contact spring recess 41 in the base element 11 in the mounted condition of the side element 12.
Advantageously, the side element 12, including the contact spring 40, is electrically conductive and the contact spring 40 is in electric contact with the screening element 14 in the mounted condition. It is then possible with advantage to establish connection with an electric circuit mass, not shown in detail, via the solder terminal 30 of the side element 12. The flat configuration of the side element 12, the contact spring 40 and the screening element 14 leads to a low-inductance mass connection that guarantees a screening effect even at high signal frequencies.
The mounting element 13 preferably is implemented in the form of a bolt extending in the plug-in direction 23. The bolt is a comparatively simple lathe work and can thus be produced at low cost. The mounting element 13 comprises at least one groove 50, extending over at least part of its periphery, that is engaged by the locating element 20 in the mounted condition. During assembly, the clip arms 21, 22 are latched in the groove 50 or are clicked into the groove 50. The clip arms 21, 22 therefore preferably have a configuration such that the clip arm 21, 22 corresponds in function to a circlip of a shaft, at least approximately.
In the mounted condition, the at least one locating element 20 secures the mounting element 13 at least against displacement in the plug-in direction 23. As in the mounted condition of the plug-in connector 10 the mounting element 13 is friction-locked on the base element 10 and, accordingly, on the plug-in contacts 15 arranged in the latter, the at least one locating element 20 contributes considerably toward increasing the pull-out force of the plug-in connector 10.
Preferably, the locating element 20 and the mounting element 13 are made from an electrically conductive material. An increased screening effect is achieved especially when the electric contact between the mounting element 13 and the screening element 14 is realized in the mounted condition by a mounting element passage 60 in the screening element 14, for example. When a tensile load acts on the mounting element 13, the electric contact resistance is lowered in the holding zones of the locating element 20 in the groove 50 with the result that the electric resistance drops and the screening effect increases correspondingly.
The mounting element 13 preferably comprises a polyhedral element 51, preferably a square element, which in the mounted condition engages a recess 52 for the polyhedral element in the base element 11. The polyhedral element 51 provides a simple means of securing the mounting element 13 against rotation relative to the base element 11.
Such means of securing the mounting element 13 against rotation is of advantage, especially, when the mounting element 13 is provided with a thread 53, preferably an internal thread, at least at its forward end. The thread 53 is intended to receive a screw, arranged on a corresponding plug-in connector, not shown in detail, that is to be screw-connected with the plug-in connector 10 according to the invention for securing the plug-in connector in its position, or on another component that is to be connected with the plug-in connector 10. In that case especially the at least one locating element 20 of the side element 12 considerably increases the pull-out force of the plug-in connector 10 according to the invention still further.
In addition, the mounting element 13 may be provided for attaching the plug-in connector 10 according to the invention to a housing not shown in detail, for example a computer housing. Such connection preferably is realized as a screwed connection.
The screening element 14 preferably comprises at least one lug 61 which in the mounted condition engages a recess 62 provided for the lug in the base element 11. During assembly of the plug-in connector 10 according to the invention, the lug 61 is bent over in the recess 62 for the lug, with the effect that the screening element 14 is friction-locked on the base element 11.
The illustrated embodiment is assumed to have two locating elements 20 provided in staggered arrangement in the plug-in direction 23 and/or in the longitudinal direction of the mounting element 13. Locating the mounting element 13 by multiple means has the effect to counteract any distortion of the mounting element 13 relative to the plug-in direction 23, thereby additionally improving the stability of the plug-in connector 10 according to the invention.
