Description

[Detailed description of the invention] electrical connection terminal device The present invention is an electrical connection terminal device comprising a casing made of an insulating material. and the casing has an edge towards the introduction side which serves to introduce the conductive wire. at least one open introduction slot located within the casing; at least one disconnectable terminal contact forming a contact connection area; The disconnectable terminal contact is oriented toward the lead-in slot and has an open edge. The present invention relates to a type having a disconnectable terminal slot for connection of electrical conductors.

Today, a wide variety of connections are used to connect electrical equipment or components to the conductive wires of the wiring. connection technology (e.g. screw technology, plug-in technology, soldering technology, disconnection technology (Schn. eidklemmtechnik)) is used. Compatible with these connection technologies Many of the correspondingly constructed connection terminal devices require a series of work steps during the manufacture of the wiring. These work steps are performed primarily manually and in some cases Therefore, it requires considerable dexterity and attentiveness on the part of the workers making the electrical connections. Ru. This is true for example when connecting an electrical device to a circuit network. This may not be much of a problem if you only need to connect a few connection terminals on the device. do not have. However, it is necessary to produce electrical connections with satisfactory contact. The required time and material consumption may be reduced when performing complex wiring with a large number of connection points. is of great significance when mass producing the same electrical equipment.

The complexity of the work steps required to produce electrical connections is particularly important for wiring automation. make automation impossible or require extremely sophisticated techniques for automation. requires technical costs.

Among the general-purpose connection technologies, the above-mentioned disconnect terminal technology has a relatively low work cost. Not required. This is because in this case, for assembly, it is necessary to simply separate the conductive wires and This is because no operation other than pushing the conductive wire into the disconnectable terminal contact is required. this Connection terminal devices constructed on the basis of the characteristics of the connection technology are known in a series of configurations. Such a known configuration can be found, for example, in the French patent, which is the starting point of the present invention. Patent Application No. 2330159, Federal Republic of Germany Utility Model No. 88043 Specification No. 88, Specification No. 8714703, Specification No. 8812057, etc. and U.S. Pat. No. 2,501,387, rMessen+PrUfen/ AutomatikJ (July/August 1982, pages 491 and 492) ) Disclosed in an article published in . constructed based on very different viewpoints. Without exception, these connecting devices must be used for complete electrical equipment or component group elements. For use in automated direct wiring (Djrcktverdraftung) It does not have the functional characteristics suitable for use.

Therefore, it is an object of the present invention to improve the electrical connection terminal device of the type mentioned at the beginning. To provide a connecting terminal device having a configuration suitable for automation, especially for direct wiring. It is.

In order to solve this problem, the configuration of the present invention uses a connection terminal device of the type mentioned at the beginning. , the casing connects to the lead-in slot on at least one side and faces towards the lead-in side. It has a slot-like or groove-like recess that was previously open, and the size of the recess is The method is as follows: conductive wires that are connected in contact at disconnectable terminal contacts The free end of the disconnectable terminal, which is located close to the contact, is protected against contact in the recess. selected, such that it is stopped and contained.

In the electrical connection terminal device according to the present invention configured as described above, the contact connection of the conductor is possible. When the conductor is disconnected, e.g. during the manufacture of electrical connections, the conductor is disconnected near the disconnectable contact. Then, complete protection against contact with the free ends of the conductors is automatically achieved. And the same Sometimes the connection terminal device also allows continuous wiring (Durchverdraftung). Therefore, all conditions for fully automatic direct wiring are given. Ru. The introduction slot in the casing allows the clamp fixation of the pushed conductive wire. When configured in this way, contact protection can be achieved. Not only the Tensile load reduction can also be achieved. Other when creating a connection The conductive wire wiring tool can be used once at each connection point, since no additional work steps are required. This is the main prerequisite for automating direct wiring. It is.

If the disconnectable terminal thrower allows a certain degree of large error when pushing in the conductor, In this sense, disconnectable terminal slots are suitable for automating such wiring. I can say that I am doing it. At the same time a flat, gas-tight contact connection of the conductors is guaranteed, In this case, the conductors are immediately connected in the form of cold welding when they are pushed in; This allows oxidation of the conductor surface, e.g. the conductor insulation layer, to be removed in a separate step. To prevent oxidation of the conductor surface, which is often seen when the conductor surface must be removed. can be done. The conductor is disconnected immediately adjacent to the disconnection contact, and the conductor is The free end automatically guarantees contact protection in slot-like or groove-like recesses. This makes it possible to work with extremely short ends, i.e. with almost no waste. It can be carried out. This makes it easier to handle large wiring jobs with multiple connection points. Considerable material savings can be made.

In an advantageous embodiment of the invention, the width of the slot-like or groove-like recess is larger than that of the introduction slot. is dimensioned to be larger than the width of the With this configuration, the recessed part It is now possible to quickly and easily disconnect the conductor at the time of contact connection. Ru. Also, in order to obtain improved contact protection and a very short construction form of the entire terminal device, 1 In a further advantageous embodiment of the invention, the slot-like or groove-like recess is provided in the introduction slot. deeper than the cut (dimensioned). When configured this way, the The free end of the conductor is bent downwardly behind the breakable contact towards the bottom of the recess. can be lost.

Basically, groove-like or slot-like recesses of the type described above are used for cutting contacts. It may be provided on one side or on both sides, and at one end. It may also be designed in the form of an open trough. However, there are also certain characteristics For certain use cases, the slot-like or groove-like recess can be configured as a chamber. In this chamber, the exposed ends of the contact-connected conductors are provided with a contact-proof IF. are accommodated. By configuring in this way, the structural length of the connection terminal device can be reduced. can be further shortened. In this case, in a further configuration of the present invention, the chamber on both sides of the disconnectable terminal contact, each limited by the associated lead-in slot. It is. With this configuration, two conductors can be selectively connected and disconnected. You can also connect the conductor on either the left or right side using the width of the connection terminal device. The connection terminal device can be used exclusively for continuous wiring. Can also be done.

Slot-like or groove-like recesses are used to facilitate the automatic introduction of conductive wires. Advantageously, the entry side is provided with an enlargement, for example formed by an introduction ramp. . The slot-like or groove-like recess also has a guide surface for the conductive wire insertion tool. You can leave it there. With this configuration, the tool can be used when introducing conductive wires and making contact contacts. It is possible to accurately guide the terminal in the correct position relative to the disconnectable terminal slot when connecting. Moreover, in this case, no additional guide device is required.

The conductive wire is disconnected at the respective connection point formed by the connection terminal device. This can be done in an automatic conductive wiring tool using a cutter. is possible. Additionally, the connecting terminal device is a conductor that is pushed into the disconnectable terminal slot. such as having at least one cutting edge for separating the electrical wires. Configuration is also possible. Cutting tips like this 1. For example, a disconnectable terminal contact In this case, the cutting edge is to work.

The connecting terminal device according to the present invention has multiple terminals even in the non-glue terminal format. It is also possible to configure the format. For this purpose, the casing is It may have fixing means integrally molded into the ring. However, if In some cases, the connection terminal device is integrated directly into the electrical switching element: It is also advantageous that the casing is equipped with such electrical switching elements. or as part of such an electrical switching element. It is organized as a department.

The connection terminals shown in Figures 1 to 7 have a rectangular cross-sectional shape and are insulated. It has a casing 1 made of material, which casing 1 is likewise made of an insulating material. It is attached to an integrally molded base portion 2 manufactured from. And this stand part 2 is configured as a through longitudinal slot 3 located near the flat bottom surface. Equipped with fixed fixing device. As you can see from Figure 3, the connection terminal is on the bottom of the , for example, attached to the base plate 4 of the electrical equipment 5 (see Fig. 10) installed in front. The base plate 4 has a section cut out from the base plate and extending upwardly. It is fixed using a connecting plate 6 that is bent in the opposite direction, and this connecting plate 6 is It passes through the longitudinal slot 3.

Both side walls 7 of the casing 1 are open upward, that is, toward the conductive wire introduction side. has two ribs 8 facing each other on its inside, both ribs 8 is located approximately in the middle between both end surfaces 9 of the casing 1, and both ribs 8 between which an introduction slot 10 (first 2 and 4), and this introduction slot 10 is for introduction at the upper side. It is enlarged by the inclined portion 11. The introduction slot 10 is in its lower range , at point 12 (Fig. 16), there is some local expansion in the partially circular area. has been done.

In the ribs 8, from the lower side to approximately the height of the introduction slope 11, there are ribs facing each other. Extending are two narrow grooves 13 (FIG. 5), both of which are made of spring steel or Bronze cut-off terminal contacts 16 with limited open-edged cut-off terminal slots 14 The two legs 15 are received. Approximately in the area of the disconnectable terminal slot 14 A thin cut-off terminal contact 16 in the form of a U-shaped small piece is located inside the casing 1. Except for the cutting section formed in the leg 15 and directed towards the cutting terminal slot 14 , fully embedded in the insulating material of the casing 1, in which case the disconnectable terminal Both legs 15 of the contact 16 are guided with limited movement in the groove 13 . The disconnectable terminal contact 16 is connected to both legs 15 in the non-slotted area. At point 17 (FIG. 3), there is a The disconnectable terminal contact 16 is introduced into a groove in which the disconnectable terminal contact 16 is axially inserted. However, it is supported.

The electrical windings of the electrical device 5 are connected via a conductor 19, and this conductor 19 is received in the insulating material molded product 20 on the head side of the electrical equipment 5. and is electrically conductively connected to the breakable terminal contact 16 at the other end. cutting The type terminal contacts 16 together with the disconnectable terminal slot 14 form the contact area of the connection terminal. are doing.

For example, as can be seen from Figures 1 to 5, the casing 1 has ribs 8 on both sides. Connecting and thus connecting to the introduction slot 10, a rectangular or somewhat (wedge-shaped) It has one groove-like recessed part 21 with a cross-sectional shape tapering to The biconcave crotch 21 opens toward the introduction side of the casing 1 next to the introduction slot 10 are doing. The groove-shaped biconcave crotch portions 21 are arranged so as to align with each other and the introduction slot 10. It is placed. The double concave crotch portion 21 is similarly limited by the introduction slope portion 22 on the upper side. has been done. As shown in FIGS. 3 to 6, the depth of the groove-shaped recess 21 is The width 23 of the recessed portion 21 is set to be thicker than the depth of the introduction slot 1o. The width is set to be significantly larger than the width of the introduction slot 10.

The dimensions of the individual parts are selected as follows. That is, in this case, the insulated When the conductive wire 24 is pushed through the introduction slot 10, as shown in FIG. As shown in FIG. At the same time, the cut-off terminal contact 16 and the terminal section are cut open by the legs 15 of 6. A gas-tight contact connection is made between the metal conductor 26 which is deformed at the It is now possible to

The inserted conductive wire 24 is simultaneously inserted into the introduction slot due to its insulating layer 25. clamped tightly between the ribs 8 in the socket 10, in this case at point 12 ( The enlarged part in FIG. 6) shows that the conductive wire 24 is serves to ensure a lock in the insulating layer 25 of. In this way, The separated end portion 27 of the conductive wire 24 connected in a fixed manner is connected to the other groove-shaped recessed portion. 21 (this will be explained in detail later with reference to Figures 14 to 16). (explained), it extends through one side of the groove-shaped recessed portion 21. groove-like concavity The width 23 and depth of the provided portion 21 and its axial length are determined by the length of the conductive wire 24 cut off. The dimensions are such that automatic contact protection is provided at the ends. Sunawa In other words, when testing the contact prevention properties of the standard contact fingers, the groove-shaped recessed portion 21 is of sufficient depth. The exposed end of the disconnected end 27 of the conductive wire 24 is It is impossible to penetrate the surface. Metal disconnectable terminal contact 1 The legs 15 of the 6 itself extend outwards in the groove 13 of the insulating material casing 12. completely protected against contact. The disconnectable terminal contact 16 is located in the area of the introduction slot 10. It is located at such a depth that it is completely protected against contact.

In the embodiment of the casing 1 shown in FIGS. 1 to 7, the introduction slot 10 is Two groove-shaped recesses 21 that are aligned with each other are provided on both sides, and these recesses The width 23 of the recess 21 and the depth of the recess 23 are smaller than the diameter of the conductive wire 24 to be received. is also set significantly large. Also, one of the groove-shaped recessed portions 21 may be omitted. It is also possible, in particular, that the conductive line 24 simply passes continuously through the contact area. This can become a problem when installed in the In some instances, groove-like depressions It is possible to omit both installation parts 21.

A variant embodiment of the housing 1 is shown in plan view in FIG. In this example, a simple One groove-shaped recess 21 is provided in the casing la. on each side by a pair of ribs 8 with an introduction slot 10 between them. It is restricted and therefore organized in the form of a chamber. Rib pair 8 is the casing In the group 1a, each end is integrally molded on the same plane as the side wall 9a. In this case, the introduction slot 10 extends in the longitudinal direction of the groove-shaped recessed part 21 forming the chamber. oriented adaxially.

In FIG. 8, in the range of both introduction slots 10, corresponding rib pairs 8 are shown. Grooves I3 are formed in each of these grooves 13, as shown in FIG. The legs 15 of the two breakable terminal contacts 16 are supported so as to be elastically expandable.

Each leg pair 15 defines a disconnectable terminal slot 14 and in this case disconnectable The terminal slot 14 is aligned with the associated lead-in slot 10. As shown in Figure 8 The embodiment described above makes it possible to disconnect the contact-connected conductors directly in the contact-connection area. Make it.

The disconnectable terminal contact 16 in the embodiment described above may simply be used as shown in FIG. 16, for example. It is only possible to make a contact connection with the pressed conductor 26 in the pressed form. It is made into Noh. It is desirable to disconnect the conductive line 24 in the area of the contact connection area. If so, this will be explained in detail later with reference to Figures 13 and 14. This is done using the specific tools described. However, also casing 1 or 1a at least one for the conductive wire 24 pushed into the breakable terminal slot 10; It is also possible to arrange cutting edges. This allows the conductive wire to be pushed in. It is possible to disconnect the conductive wires at the same time.

An embodiment for this is shown in FIG. 9: the case is shown in FIG. The disconnectable terminal contact 160 inserted into the ring 1 has two spring-elastic metal parts. The legs 150 are likewise mounted in the two grooves 13 in a limited and expandable manner.

The disconnectable terminal contacts 160 are however on both sides of the legs 150, facing upwardly. It has two cutting edges 28. In this case both cutting edges 2 8 at a right angle to the lead-in slot 10 at a small distance laterally from the leg 150 , and a U-shaped, integrally formed, disconnectable terminal contact 160 . The lower leg portion 29 is configured with a lower leg portion 29. Cutting edge 28 has an introduction slot 10 at a certain distance above the bottom 30 of the The conductive wire 24 pushed through the introduction slot 10 makes contact with its conductor 26. After connection, push one cover downwards in the disconnectable terminal slot 14. It is pressed against the cutting edge 28, and this one cutting edge 28 can be completely separated.

In Figure 9, both cutting edges are located inside the rib 8, so the conductive wire The cut surface of 24 will still remain inside the side edge of the introduction slot 10.

However, it is also basically possible to move the cutting edge 28 somewhat wider to the side. 50 can be separated from each other, and furthermore, it is also possible to separate the disconnectable terminal contact 160. It is also possible to assign one cutting edge 8 to each.

The connection terminals described in FIGS. 1 to 9 are, as already mentioned, independent connection terminals. As a child device, it can be used for various electrical devices, switching and configuration group elements. can be assigned, including component wiring boards. Examples for this purpose are shown in Figure 3 and 10, in which case two terminals are connected to the casing 1. together with a magnetic electrical device 5 in the form already described, which is prefixed to the gas discharge lamp. located on the base plate.

The connecting terminal is in this case a double connecting terminal, indicated by the reference numeral 31 in FIG. (In the example of FIG. 11, This double connection terminal 31 is a double connection terminal 31 of the same type as shown in FIG. The four terminals together with the connecting terminals 32 are arranged on a stand 33 made of an insulating material. This insulation material A capacitor 34 is fixed to a stand 33 made of For example, double connection terminals 31 with disconnectable terminal contacts and electrical It is connected. The double connection terminal 31 is basically as shown in Figures 1 to 7. It has a similar structure to the connection terminal described above, and the difference in this case is simply that: be. In other words, in this case, these two connection terminals are combined into one unit. Both casings 1b of this unit are separated from each other by a slot 34. This slot 34 extends somewhat beyond the depth of the groove-like recess 21. and has a common continuous base portion 2b integrally molded, and this base portion 2 b has a cross-sectional shape as shown in FIG.

Depending on the shape and configuration of the electrical equipment or component to be connected, The device may also be an integral part of this electrical equipment or component. good. Such an embodiment is for the rod-shaped gas discharge lamp shown in FIG. The lamp socket 35 has a fixed foot 36 integrally molded from plastic. This fixed foot 36 basically has a structure as shown in FIGS. 1 to 7. Both casings 12 of the two connecting terminals are molded. Double connection terminal device The axis of the groove-shaped recess 21 is the axis of the gas discharge lamp inserted into the lamp socket 35. oriented at right angles to the longitudinal direction of the In this case, the groove-like [! ! L.

The basic structure of the crotch portion 21 corresponds to that shown in FIGS. 1 to 7, so , I won't mention it again here (.

The connecting terminal device according to the invention is particularly suitable for automation for automatic direct wiring. It has a certain amount of structure. For this, see Figures 13 and 14 below. With reference to: In automatic direct wiring, a conductive wire wiring tool, indicated only partially by the reference numeral 37, is used. , for example, by an industrial robot (not shown) controlled according to a program. It is now possible to move along a predetermined trajectory on the assembled electrical equipment. There is. This track corresponds to a conductive wireway and is an individual electrical component. It extends between each connection point. These connection points are shown in Figure 1. It has a connection terminal device of the type shown, i.e. each connection point has a The upper part of the casing in FIGS. 13 and 14 is shown in FIG. It is shown that there are The conductive wire wiring tool 37 has a rectangular cross-sectional shape on its lower side. It has a rigid conductive wire routing finger 38 with The width of the conductive wire wiring finger 38 is determined by the movement play required for the width 23 of the groove-like recess 21. (See Figure 7). There is a conductive wire guide inside the wiring finger 38. An inner passage 39 is configured, and a conductive wire guide passage 39 is provided with a conductive wire through a feeding mechanism. Provided with conductive wire drawn endlessly from a coil or similar It looks like this. Further, this conductive wire guide passage 39 is opened at a vertical side surface 40 by °C. It opens at an opening 41, and in this case, the conductive wire 24 extends from this opening 41. The parts are oriented horizontally as can be seen in FIG.

spaced in front of the flat side surface 41 and oriented parallel to this side surface 41; 1. A plunger 42 is provided. Second plan)? 42 is a conductive wire The conductive wire wiring tool 37 is supported so as to be slidable in the vertical direction along the conductive wire wiring tool 37. And, this plunger 42 has its pressing surface 43 protruding from the opening L141. The conductive wire 24 can be supported by a horizontal portion of the conductive wire 24 . As a result, the conductive wire 24 The horizontal part is located on the one hand in the pressing surface 43 and on the other hand in the area of the opening 41. Thus, the conductive wire guide passage 39 is reliably supported at the upper edge thereof.

An intermediate chamber 44 is defined in the opening between the plunger 42 and the side surface 40, and this intermediate chamber The width of 44 is the same as the width of the rib pair 8 of the casing 1, or is slightly larger than the width of the rib pair 8. big. The inner body of the plunger 42 has a rectangular cross-sectional shape. relative to the drawing plane The width of the vertical plunger 42 is, in the illustrated embodiment, the width of the introduction slot 10. It corresponds to the sum of the necessary athletic play. However, also the plansha 42 It is also possible to select the width to correspond to the width 23 of the groove-shaped recess 21.

In automatic direct wiring, the conductive wire wiring tool 31 is connected to the sensor hand by an industrial robot. In cooperation with the stage, the casing of the connection terminal device at the connection point can be accurately positioned and 12 and the overall result is the position shown in FIG. That is, the plunger 42 is also positioned such that it occupies its pushed-out support position. It will be occupied.

Then, the conductive wire wiring tool 37 is directed vertically downward with its wiring finger 38. At this time, the wiring finger 38 moves into the groove-shaped recess 21 on the right side. As shown in Fig. 14, the plunger 4 enters from the 1st position, and at the same time plunger 4 2 enters the groove-shaped recess 21 on the left side and partially enters the introduction slot 10. Slip into it. In this case, the disconnectable terminal contact J6 is connected to the side surface 40 and the plunger 42. It is located in an intermediate chamber 44 between the two.

During such a downward movement of the conductive wire wiring 1 tool 37, the pressing surface 43 and the upper side of the opening 41 held precisely at two points on both sides of the disconnectable terminal contact 16 between The conductive wire section that is connected and supported is passed through the lead-in slot 10 from above to the cutaway terminal. is pushed into the slot 14, and this movement causes the conductive wire portion to move into the enlarged portion 12 (the 6) until it reaches the inside and is locked in this enlarged part 12. by this On the one hand, a satisfactory contact connection of the electrical conductor 26 at the disconnectable terminal contact 16 is achieved. and on the other hand, the electrically insulating layer 25 of the conductive line 24 is inserted into the introduction slot. Clamping in the transverse direction between ribs 8 facing each other in the tray 10 and eventually become fixed. The conducting wire 24 is therefore now in a gas-tight contact connection. Not only is the tensile load reduced in the insulating layer 25, it is fixed. (See Figure 16).

Such conduction of conductive wire 24 into lead-in slot 10 and breakable terminal slot 14 During the input movement, the groove-shaped recess 21 connects the wiring fifts to both the slots 10.14. guaranteeing perfect lateral alignment of the plunger 38 and plunger 42. Ru. Small assembly errors of the connection terminal device are compensated for by the inner body of the introduction inclined portion 22. be compensated. Further, the side surfaces of the groove-shaped recessed portion 21 function as guide surfaces.

When it is desired to simply route the conductive wire 24 continuously at the connection point, After introducing the conductive wire 24 into the introduction slot 10 and after introducing the conductive wire 24 into the cut-off terminal slot 14 After the contact connection of the conductive wire 26 at , the plunger 112 is simply connected to the conductive wire wiring tool. The industrial robot The conductive wire wiring tool 37 and its wiring fingers 38 are programmed in advance. the next connection point with a connection terminal device of similar configuration along the track and control as shown in FIG. And in this case the conductive wire During such a process movement of the wiring tool 37, the required conductive wire length is It is supplied synchronously via the conductive wire guide path 39.

However, if it is desired to disconnect the conductive wire 24 at the connection point, For example, a disconnectable terminal contact 160 as shown in FIG. 9 is installed at this connection point. and one cutting of this disconnectable terminal contact 160. At edge 28, plunger 42 disconnects conductor 26 after contacting.

In this case, the plunger 42 simply forces the conductor 26 onto the cutting edge 28. It's just that. However, as an alternative, the control in the conductor wiring tool 37 It is also possible to use a cutting blade 45 for this purpose, which cutting blade 4 5 is supported on the side surface 40 so as to be slidable in the vertical direction along the side surface 40. The cutting edge 46 of the cutting blade 45 moves from the rest position shown in FIG. It can be moved forward to the disconnection point shown in the figure, and this disconnection point At this point, the cutting edge 46 cuts the opening 41 while cutting off the conductive wire 24. It's crossing.

The cutting blade 45 is arranged as follows, that is, the cutting blade 45 is inserted into the groove-shaped recessed part of the casing 1. 21. The cutting blade 45 is a cutting edge 46 It has an inclined surface 47 connected to it, and this inclined surface 47 is connected to the introduction step during the cutting operation. Approximately the conductive wire end 27 clamped at the insulating layer 25 in lot 10 The exposed gold of the conductor 26 is bent downward by 90 degrees, thereby The metal cut surface is oriented approximately toward the bottom of the recess 21 (see FIGS. 14 and 14). (See Figure 15).

After the conductive wire 24 is cut off in this way, the cutting blade 45 and plunger 42 are separated. is again returned to its rest position, i.e. the conductive wire wiring tool 37 is It moves away from the connection point that has the state shown in Figure 15.

The depth, width, and length of the groove-shaped recessed portion 21 are as follows, that is, the length of the metal conductor 2 The cut surface of No. 6 is selected so that it cannot be touched from the outside, so the cut surface shown in Fig. 14 is When the current disconnection operation is completed, the conductive wire end 2 at the connection point is automatically disconnected. 7 contact-proof measures are warranted, and in this case further separate measures are required for this purpose. There is no need to take any action.

When a connecting terminal device configured as in the embodiment shown in FIG. 8 is used, The separated conductive wire end 27 is located in the chamber-shaped recess 21, In this recessed portion 21, the conductive wire end portion 27 is similarly reliably prevented from contacting. However, at the same time the connecting terminal arrangement is constructed with a relatively short construction length. It can be done. Moreover, in this case, it is possible to connect the two conductive wires from both sides. It is possible.
