Daut + Rietz GmbH
D-90411 Nur~herg PLUG-IN ~ohN~ ~ ~K SLEE~:
The present invention relates to a plug-in connector sleeve according to the preamble of Patent Claim 1. Such a plug-in connector sleeve is disclosed in German Patent 21 48 805.
Such plug-in connector sleeves are applied, in particular, in automobiles, where they are exposed to adverse external circumstances such as vibrations and dirt. Conventional plug-in connector sleeves of this type permit the plug parts to vibrate relative to one another to an extent which can lead to fretting corrosion on the contact points, the result being an increase in the contact resistance. Micromovements caused by thermal expansion, or vibrations can expose a surface which in turn is oxidized and grows to form an insulating layer, entailing poorer contact.
It is the object of the present invention to improve a plug-in connector sleeve of the type mentioned at the beg;nn;ng in such a way as to improve the static precision, hence reducing the possible degrees of freedom of the plug-in system and thus le~;ng to ~nh~nced resistance to fretting corrosion.
This object is achieved in accordance with the claim. Subclaims characterize preferred embodiments of the present invention. The measures according to the invention, in particular the fact that, in conjunction with a linear type of contact, the free ends of the contact segments are situated far apart from one another, lead to a higher static precision of the system, and thus to a higher resistance to fretting corrosion.
An exemplary embodiment of a plug-in contact sleeve is explained below in more detail with reference to the drawings, in which:
Figure lA shows a top view of a plug-in connector sleeve according to the invention;
Figure lB shows a side view of a plug-in connector sleeve according to the invention;
Figure lC shows a section through a plug-in connector sleeve according to the invention along the line A-A according to Figure la, Figure 2 shows a sheet-metal blank of the plug-in con-nector sleeve, Figure 3A shows the plug-in connector sleeve with a slip-on spring in top view,~0 Figure 3B shows a side view of the plug-in connector sleeve shown in Figure 3a, with a slip-on spriAg, and Figure 3C shows a section along the centre line according to Figure 3a of the plug-in connector sleeve and the slip-on spring.
The plug-in connector sleeve 1 shown in Figure 1 has a plug-in region 2 and a conductor connection region 3. The plug-in region has the form of a housing 4 in the shape of a box and has two side walls S, 6, a floor 7 and a roof 8.
Connected to the two side walls 5 and 6 and located at the front on the plug-in region 2 is a cent-ring web 17 which, in conjunction with a slip-on spring 19 (~ee Figure 3), facilitates plugging a flat connector without any problem. A middle web 18 serves to stiffen the plug-in region 2 and to guide the slip-on spring 19 (see Figure 3).
Figure 2 ~hows a sheet-metal blank of the plug-in connector sleeve. The floor of the box-shaped housing is formed by the contact segment 11 with its free end 14 with the contact segment 10 with its free end 15. The two side walls 5 and 6 are bent upwards from the sheet-metal blank. The roof 8 of the housing is formed by the two contact segments 12 and 13. The four contact segments 9 to 12 are bent with their free ends 13 to 16 into the interior of the housing, 80 that they enclose an angle of less than 90~ with the walls 5 and 6. The two upper contact segments 9 and 12 and the two lower contact segments 10 and 11 mutually overlap one another, as may : ' be seen in Figure lA in Section C-C. Owing to the over-lapping of the segments 9 to 12, the free ends 13 to 16 have contact lines situated apart from one another, thus enhAncing the static precision of the system. The result is improved protection against vibrations and a greater resistance to corrosion.
The front centring web 17 and the middle web 18 are fastened to the side walls 5 and 6, in order to reduce the spring action of the contact segments 9 to 12.
The result of the special position of the contact seg-ments 9 to 12 is that when a flat connector slides in the two spring-like contact segments 10 to 13 are firstly deflected, which facilitates insertion, and the two rear contact segments 10 and 12 are not deflected until later depths of insertion, with the result that the full contact force is then achieved. Following the middle web 18, the floor has a cutout 21 in which the slip-on spring of Figure 3 can be fastened.
In order to prevent excessive deformation of the contact segments 9 to 12, and to enhAnce the tightness of the seating of a plug-in contact in the sleeve, the latter is surrounded by a slip-on spring 19, as shown in Figure 3. The slip-on spring can be produced 'rom a hard elastic material such as steel, for example. It has inwardly rounded edges in the front region, in order to facilitate plugging in a flat connector. The aim of the slip-on spring 19 is to prevent asymmetric insertion of a flat connector from b~n~;ng outwards the lower contact segments 10, 11 and the upper contact segments 9, 1~
The plug-in connector sleeve according to the invention proves to be extremely compact and robust in shape, which renders it possible for the plug-in connec-tion sleeve to be produced simply and in a way which can be automated. Furthermore, assembly rotated by 180~ is possible because of the symmetrical design of the contact segments.
The preceding description of an exemplary embodi-ment is not to be understood as restrictive, but serves only to explain the present invention.
