Description
Title ELECTRICAL CONNECTING DEVICE AND COLORED STRIP
Background of the Invention This invention relates to an electrical connecting device comprising a housing with connecting means for at least one conduc-tor, and means for coupling to another electrical device, the housing being provided with colored identification means.
With the increase of the packing density in electronic appli-ances and with the increase in functional applications of the parts of electronic circuits, components of the circuits are colored to an ever increasing extent. This also applies to electrical con-necting devices. Often one and the same typ0 of connecting device is used on the same printed circuit board and/or on other boards inside the same electronic housing of an appliance. Each of said connecting devices provides a connection within this space, but will, in general, have a different electronic function, such as power, signal, ~requency differentiation etc. and it is undesirable to interchange the connections during manufacture, test or repair.
In order to provide a clear distinction, each connecting device inside the appliance i5 provided wikh a separate color in order to distinguish the different electrical functions.
~ , One way of achieving these different colors is to manufactu-re the connecting devices from differently colored resins. In relation to the production o~ such differently colored connecting devices, the costs will obviously be increased. In addition, diffe-rently colored connecting devices have to be kept in stock and the production will become less flexible because different batches have to be manufactured. Finally, between the production of two diffe-rently colored identical connecting devices, the injection molding machine has to be cleaned, with corresponding loss of material intervening between the two intended colors.
~ .
US Patent 4,820,193 discloses a connector in which a housing with one color is always used. The position at which the separate conductors have IO be provided in the connecting device is indicated with the aid of paint dots on the housing. To protect this colored material, a cover plate over the housing is provided with openings. Such a structure is cumbersome to achieve, the working life of the color indication also being doubtful. In addition, especially in small connecting devices, great accuracy is required for positivning the codings.
Summary of the Invention The object of the present invention is to provide a connect-ing device which does not have the abovementioned disadvantages.
This is achieved with an electrical connecting devicecomprising a housing with connecting means for at least one conduc-tor, and also means for coupling to another electrical device, in which the housing is provided with colored identification means, said colored identification means comprising a recess provided in the housing and having snap-locking means as well as a coding member which can be introduced in the recess, wherein the cross section of the recess decreases in the direction o~ the introduc-tion opening and in that the coding device is a colored codingdevice and has ~ shape corresponding to the recess, and in that after introduction in the recess less than the half of the volume of the coding member projects from the recess. By mounting the coding device in a recess it is not necessary to include a cover plate for protecting the coding device. In addition, the coding device can be provided in the recess in a very simple manner withvut particular measures and there is no danger of the color indication being affected by wear and the like.
According to an advantageous embodiment of the invention, the coding device is cylindrical. Such a coding device can be achieved in a particularly simple manner by cutting off a certain part from a continuous strand and fitting it into the recess.
According to a further advantageous embodiment of the inven-tion, the coding device is spherical. In that case, it is possible to provide different recesses in the electrical connecting device and, by placing differently colored spherica~ inserts therein, a very wide ranga of codings car. be achieved.
With the device according to the invention, it is possible to realise codings in the final stage of the production. This is comparatively less costly compared to completely providing connect-ing devices with different colors and gives a better usage of the material for the connecting device.
According to a further advantugeous embodiment, the recess is provided with snap-locking means. In that case, the coding device can be fitted in the recess in a particularly simple manner and fixed therein.
The coding device according to the invention may be used both to indicate the position of separate conductors with respect to a connecting device in the case in which more than one conductor has to be coupled to a connecting device and for mutually distinguish-ing different connecting devices.
According to a further advantageous embodiment, the at least one recess is provided near the edge of the housing. This achieves optimal visibility from different sides of the housing, which is of importance if the electrical connecting devices are received in different positions in an electrical housing.
The present invention also relates to a colored strip from which the coding devices which have to be used in the electrical connectlng device which is described above can be obtained by division.

Brief Descrip~ion of the Drawin~_ The invention will be illustrated below with reference to an exemplary embodiment shown in the drawing. In the latter, Figure 1 shows an electrical connecting device according to the invention in plan view; and Figure 2 shows the electrical connecting device according to Figure 1 in side elevation and partially in section along the line II-II in Fig~ 1.
Detailed Description of the Embodiments In Figure 1, an electrical connecting device is indicated as a whole by 1. It comprises a housing 2 having conductor-receiving channels 3. In the figures, the conductors, in this case a flat cable, are not depicted. Housing 2 is provided with several ope-nings 4 at the left-hand side and with an oblong opening 5 at the right-hand side. The form of the openings 4 is more particularly evident from Figure 2. It is evident that this is provided with a snap-locking edge 6 at the top. As is evident from Figure 2, a spherical coding device 7 having a predetermined colour is intro-; duced into the opening 4~ A cylindrical coding device 8, also having a predetermined colour, is introduced into opening 5.
Because seve~al openings 4 are present, a large number of coding -~ combinations can be achieved with a limited number of colours.
Sphere 7 snap-locks along the snap-locking edge 6 when introduced and is thereby secured. It is evident that both cylindrical coding device 8 and spherical cocling device 7 project to some e~tent and, because they are provided near the edge of the housing 2, they can be observed both from above and from the side. Spherical device 7 can be manu~actured in all the ways known in the prior art. The oblong coding device ~ is preferably manufactured by cutting a strand of material. ~lousing 2 is provided with contact pins 9 and 2 ~ L~
centring pins 10.
Although not depicted here, it is also possible to provide the recess 4 or 5 in surface 11, with the result thst a coding is provided for the positioning of the conductors, not depicted in more detail, with respect to the channels 3 intended therefor.
Solely spherical coding devices or cylindrical coding devic0s may also be used at only one position in the connecting device. These and all other embodinents which are obvious to those skilled in the prior art are within the scope of the present invention.
