Definitions
- the present invention relates to a plug-in connector sleeve according to the preamble of Patent Claim 1.
- a plug-in connector sleeve is disclosed in German Patent 21 48 805.
- 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.
- 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 5, 6, a floor 7 and a roof 8.
- centring web 17 Connected to the two side walls 5 and 6 and located at the front on the plug-in region 2 is a centring web 17 which, in conjunction with a slip-on spring 19 (see 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 shows 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, so 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 1A 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 segments 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.
- the floor has a cutout 21 in which the slip-on spring of Figure 3 can be fastened.
- the slip-on spring 19 can be produced from 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 bending outwards the lower contact segments 10, 11 and the upper contact segments 9, 12.
- 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 connection 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.

Abstract
Description
- 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 inGerman 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 beginning in such a way as to improve the static precision, hence reducing the possible degrees of freedom of the plug-in system and thus leading to enhanced 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 1A
- shows a top view of a plug-in connector sleeve according to the invention;
- Figure 1B
- shows a side view of a plug-in connector sleeve according to the invention;
- Figure 1C
- shows a section through a plug-in connector sleeve according to the invention along the line A-A according to Figure 1a,
- Figure 2
- shows a sheet-metal blank of the plug-in connector sleeve,
- Figure 3A
- shows the plug-in connector sleeve with a slip-on spring in top view,
- Figure 3B
- shows a side view of the plug-in connector sleeve shown in Figure 3a, with a slip-on spring, 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-inregion 2 and aconductor connection region 3. The plug-in region has the form of ahousing 4 in the shape of a box and has twoside walls 5, 6, a floor 7 and aroof 8. - Connected to the two
side walls 5 and 6 and located at the front on the plug-inregion 2 is acentring web 17 which, in conjunction with a slip-on spring 19 (see Figure 3), facilitates plugging a flat connector without any problem. Amiddle web 18 serves to stiffen the plug-inregion 2 and to guide the slip-on spring 19 (see Figure 3). - Figure 2 shows 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 itsfree end 14 with thecontact segment 10 with itsfree end 15. The twoside walls 5 and 6 are bent upwards from the sheet-metal blank. Theroof 8 of the housing is formed by the twocontact segments contact segments 9 to 12 are bent with theirfree ends 13 to 16 into the interior of the housing, so that they enclose an angle of less than 90° with thewalls 5 and 6. The twoupper contact segments lower contact segments segments 9 to 12, thefree 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 themiddle web 18 are fastened to theside walls 5 and 6, in order to reduce the spring action of thecontact segments 9 to 12. The result of the special position of thecontact segments 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 tworear contact segments middle web 18, the floor has acutout 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-onspring 19, as shown in Figure 3. The slip-on spring can be produced from 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-onspring 19 is to prevent asymmetric insertion of a flat connector from bending outwards thelower contact segments upper contact segments - 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 connection 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 embodiment is not to be understood as restrictive, but serves only to explain the present invention.
