Definitions

• the invention relates to a plug for electrical connection with a plurality of insulated wire ends, comprising a prism-like housing which has a flat side oriented parallel to the plugging direction, which housing has a plurality of closely adjacent channels which are at least approximately parallel to one another and to the flat side for channels therein contains pluggable wire ends and which housing furthermore has a plurality of transverse slots in the front area in the plug-in direction from the flat side, each transverse slot opening into one of the channels and a plate-shaped contact lamella being insertable in each transverse slot.
• a plug of this type is known as a western plug (because it was first marketed by the westernelectric company).
• the particular advantage of this connector is that the wire ends together with their insulation can be inserted into the channels.
• the contact lamellae which are of course still withdrawn from the channels, are then pressed into the wire ends fixed in the channels with a simple pressing tool. They cut through the insulation and make contact with the copper souls.
• the contact lamellae form the contacts of the plug with their edge surfaces which are approximately flush with the flat side.
• the wire ends In order for the contact between the contact lamella and the copper core to be reliable, the wire ends must be kept in the channels with as little play as possible.
• the object of the invention is to provide a connector of the generic type which can be adapted to different wire diameters in a more cost-effective manner.
• the housing consists of an inner part and an outer part, the inner part being insertable into the outer part, which outer part has the flat side with the transverse slots and which inner part has the channels and a bottom side facing the flat side , wherein the channels have in a front portion in the direction of insertion towards the bottom side transverse slot sections, each aligned with a transverse slot of the outer part when the inner part is arranged in the outer part.
• the advantage of this structure is that the outer part can be used as the far more expensive part of the plug (it also includes a metallic shield and cable surround) regardless of the respective wire diameter. Only the simpler inner part needs to be produced in variations with channels of different widths.
• the inner part is so inexpensive that, for example, three variants for the three most frequently occurring wire diameters are removed together with an outer part. can deliver. The fitter then has the option of completing the connector to match the existing cable.
• Another advantage is the handling when inserting the cable ends into the ducts, because this insertion can take place as long as the inner part is not yet in the outer part and the shielding of the plug does not yet cover the duct openings.
• the inner part can be inserted into the outer part in the manner of a drawer. This is favorable in terms of manufacture and application.
• An embodiment is preferred according to which the inner part can be inserted into the outer part in a direction parallel to the flat side and can be locked in the inserted state.
• the sliding direction is therefore perpendicular to the direction of the contact lamella.
• the pressed-in contact lamellas thus already act as a lock.
• the inner part can be inserted into the outer part in the direction of the plug-in direction of the plug.
• the outer part need only have a chamber that is open to the rear, and the cable can protrude through the opening that is present anyway. Lateral deflection forces, which are transmitted from the cable to the plug, also act on the form-fitting border between the inner part and the outer part, so that greater stability is achieved.
• the inner part has a front end face in the plugging direction and one at a distance from it arranged rear end face, as well as two opposite side faces and projecting transversely to the bottom side, the distance between the end faces being smaller than the length of the outer part.
• the length of the webs is fixed in such a way that their rear ends lie outside the outer part when the inner part is arranged in the outer part. This can be used to release the locking device, if necessary, without special tools.
• the plug is very flat if the center axes of adjacent channels are arranged in a common plane that is parallel to the flat side.
• the maximum permissible wire diameter is then limited by the available width of the inner part and the number of wire ends to be distributed thereon. Therefore, if the center axes of adjacent channels are arranged in two different planes, each parallel to the flat side, an equal number of considerably thicker wire ends can be accommodated. However, this makes the plug somewhat higher.
• Fig. 2 is a front view of the outer part in the direction of arrow 2 of Fig.1 y
• FIG. 3 shows a rear view of the outer part in the direction of arrow 3 from FIG. 1,
• FIG. 5 is a front view of the inner part in the direction of arrow 5 of Fig.1,
• FIG. 6 shows a section through the inner part according to the section plane 6-6 in FIG. 5,
• FIG. 7 shows a section in the plane 7-7 of FIG. 6, partly broken away
• FIG. 8 is a bottom view of the inner part in the direction of arrow 8 in FIG. 1st
• FIG. 9 is a front view corresponding to FIG. 5 according to a variant in FIG partially broken representation.
• the plug consists of an outer part 15 of generally prismatic shape and a flat, likewise prismatic inner part 1 6.
• the outer part has a front wall 18 in the insertion direction according to arrow 17, A rear wall 19, parallel to one another, two mutually parallel side walls 21, 22, a top wall 23 and a bottom wall 24 parallel to it, a spring bracket 25 stands up from the top wall 23, which serves to insert the plug into a (not particularly shown here) ) To lock the socket.
• the lower wall 24 is stepped in the side view of Figure 1, so that from the rear wall 1 9 starts a wall section 26, which is lower compared to a flat side 27, which adjoins the front wall 1 8.
• the rear and middle part of the outer part is covered by a metal shield 28.
• the outer shape of the outer part 1 5 corresponds to that of a commercially available WESTERN plug, at least essentially and therefore need not be explained in more detail.
• a chamber 29 open to the rear wall 19, the shape of which can best be seen from FIGS. 3 and 4.
• the chamber is also approximately prismatic and is divided into a front part 32 and a rear, further part 32, which is intended to receive a cable end with its shielding exposed there and to fix it in a known manner.
• the front part 31 has a lower inner wall 33 which is aligned parallel to the flat side 27.
• the inner part 1 6 corresponds in its dimensions and its shape to the front part 31 of the chamber 29 and can be viewed from the rear wall 1 9 in a direction parallel to the flat side 27 in the manner of a push insert the drawer into this part 31 with little play.
• the inner part 16 has a front end face 34 and a rear, stepped front face 35, the distance between them corresponding to approximately half the length of the outer part. Furthermore, it has two opposite, parallel side surfaces 36 and 37, and a bottom side 40 which, when inserted, rests on the lower inner wall 33 of the front part 31 of the chamber 29.
• FIGS. 5 to 8 clearly show, two lateral narrow webs 38 and 39 protrude rearward from the rear end face 35, the outer sides of which are aligned with the side faces 36, 37.
• the height of the webs 38, 39 in the side view according to FIG. 1 or 6 corresponds to the height of the rear part 32 of the chamber 29, so that the webs are guided therein with little play and offer the inner part 16 an additional support.
• On the lower edges 41 of the webs 38, 39 also downwardly projecting locking cams 42 are formed, which engage in correspondingly designed locking recesses 43 (FIG. 4) in the rear part 32 of the chamber 29 when the inner part 16 in the chamber 29 of the outer part is full is inserted.
• the length of the webs 38, 39 is dimensioned such that their rear ends 44 are still a few millimeters outside the outer part 15.
• the inner part 16 contains a predetermined number (usually eight) of channels 45 which are parallel to one another.
• the center axes of the channels 45 extend at least approximately parallel to the bottom side 40 and lie in a common parallel thereto.
• a cross slot section 47 which opens out to the bottom side 40, extends from each channel 45 and is aligned with a cross slot 48 (FIGS. 2 and 4) arranged in a corresponding position in the outer part 15.
• the transverse slots 48 each have a plate-like shape Contact lamella 49 exactly in the manner of the known connector too.
• the channels 45 and transverse slot sections 47 are formed continuously up to the front end face 34, which enables a more favorable injection molding tool.
• a cable 51 is indicated with dashed lines in FIG. 8, the exposed shield 52 of which lies in the space between the webs 38, 39.
• the wire ends 53 emerging from the sheathed shield 52 have insulating jackets marked in different colors and it is the task of the installer to insert certain wire ends into respective channels 45.
• a color mark 54 can be applied to the bottom side 40 of each channel. For example in the form of an embossed letter code.
• the fanned-out wire ends 53 are inserted into the channels 45 with the outer part 15 removed, so that the position of the channels 45 is clearly visible.
• the outer part 15 is pushed over the inner part 16 until the locking cams 42 snap into the locking recesses 43.
• the cable end with the exposed shield 52 is pressed into the rear part 32 of the chamber 29 and metal parts of the metal shield 28 projecting from there are contacted.
• the contact blades 49 are then pressed into the channels 45 by means of a pliers-like tool, so that they cut through the insulation of the wire ends 53 and contact the wires in each case. Their outer edge surfaces 55 then form the contacts of the plug.
• channels 56 and 57 which are alternately offset in terms of height, according to FIG. 9.
• the channels 56 lie in a common plane 58 and the channels 57 in another common plane 59, which is closer to the bottom side 40.
