The conductive rope channels 12 penetrate through the inside of the shell 10 and are communicated with two side walls of the shell 10, the conductive rope channels 12 comprise threading pipes 120 arranged in the shell 10 and threading through holes 121 arranged on the side walls of the shell 10, the threading pipes 120 are communicated with the threading through holes 121 at two ends and are used for penetrating through the conductive ropes 2, at least one threading through hole 121 of each conductive rope channel 12 is provided with a power supply fixing terminal 13, terminal inner holes 130 communicated with the threading pipes 120 are arranged in each power supply fixing terminal 13, the terminal inner holes 130 are used for penetrating through the conductive ropes 2, the power supply fixing terminals 13 are electrically connected with a power supply end of the information display module 11, and the electric connection can be that a shell of each power supply fixing terminal 13 is electrically connected with the power supply end of the information display module 11 through wires in the shell 10. The power supply fixing terminal 13 includes a fastener 131, and the fastener 131 is used for fixing the penetrating conductive rope 2 and electrically connecting with the conductive rope 2.

The casing 10 of the present invention is used for supporting the entire information board 1 and internal components, and may have a flat square shape, and may have arc corners around, such as a common tablet computer, and may be a metal casing 10 or a plastic casing 10. The interior of the information board shell can be in a flat plate shape, the outer side of the information board shell surrounds the strip-shaped side wall, and a flat accommodating cavity for accommodating components and information display modules 11 is formed between the side wall and the flat plate-shaped interior. The threading pipe 120 is used for guiding the conductive rope 2 to penetrate through the threading through holes 121 on two side walls of the shell 10, and can be directly fixed inside the shell or through the threading pipe groove arranged inside the shell 10, the threading pipe groove can be a square groove formed in the shell, the top surface is open, the bottom is closed, and the threading pipe can be placed in the threading pipe groove. In some embodiments, the threading tube 120 may be replaced with a semi-cylindrical recess in the interior of the housing 10 and a semi-cylindrical recess in the rear cover, which may be combined with a semi-cylindrical recess 15 in the middle of the housing 10 to form a cylindrical through hole when the rear cover is covered on the housing 10, to perform a similar function to the through hole in the middle of the threading tube 120. In the present invention, the use of the wire pipe 120 can avoid the hole forming of the conductive rope channel 12, and particularly in the case of a display screen in front, it is difficult to realize a semi-cylindrical groove, and the use of the wire pipe 120 can reduce the cost of the die and improve the product development efficiency. The threading tube 120 is preferably a circular tube, in some embodiments square tubes, etc., as long as threading of the conductive cord is achieved. The material of the threading tube 120 may be selected from a metal tube or a plastic tube, preferably a metal tube, so that the wall thickness of the threading tube may be relatively thin, thereby facilitating the reduction of the entire thickness and avoiding affecting the entire thickness of the information board.

In order to facilitate threading of the conductive cord 2, the axes of the threading through hole 121, the threading tube 120, and the terminal inner hole 130 are preferably aligned.

And, in the present invention, the power supply fixing terminal 13 may be entirely made of metal material, so that when the conductive cord 2 is in the power supply fixing terminal 13, the entire power supply fixing terminal 13 may be in contact with the conductive cord 2 to form an electrical connection, and then the power supply fixing terminal 13 is electrically connected with the information display module 11. Or in some embodiments, the power supply fixing terminal 13 is an insulating member (such as a plastic member) and is internally provided with a conductive member, and the conductive member is communicated with the terminal inner hole 130 of the power supply fixing terminal 13 and the outside, so that the conductive rope 2 in the power supply fixing terminal 13 is electrically connected with the external information display module 11. The power supply fixing terminal 13 is made of metal in the whole in the preferred embodiment, so that reliable electrical connection can be formed.

The conductive cord 2 may also be made of a wire or wires of a plurality of strands, the radius of which should be uniform along the length to facilitate passage through the conductive cord passage 12.

When the embodiment is used, the fastener 131 is firstly loosened, then the two conductive ropes 2 respectively penetrate through the conductive rope channels 12, the conductive ropes 2 can sequentially penetrate through the terminal inner holes 130, the threading pipes 120 and the threading through holes 121 of the power supply fixing terminals 13, and then the fastener 131 and the conductive ropes 2 are fastened, so that the fixed connection and the electric connection of the conductive ropes 2 and the whole information board 1 are realized. And then the two conductive ropes 2 are respectively connected with the two ends of the power supply 3, so that the power of the power supply 3 can be supplied to the information display module 11 of the information board 1 through the conductive ropes 2 and other power utilization modules for use, and information display is realized.

According to the invention, the threading pipe 120 is arranged in the information board 1, so that long-distance threading of the conductive rope 2 can be realized, and then the conductive rope 2 can be quickly fixed through the fastener 131 of the power supply fixing terminal 13 on the side wall, and the front display of the information display module 11 is not influenced. And then the electric connection of the information board 1 can be realized by connecting the electric conduction rope 2 with the power supply 3. Thus, the fixed connection and the electric connection are completed, the connection efficiency of the information cards 1 is greatly improved, and a plurality of power supplies are not needed for supplying power when a plurality of information cards 1 are displayed, so that the display device is more attractive.

In the assembling process of the information board 1 of the present invention, the power supply fixing terminal 13 may be fixed to the housing 10, then electrically connected, and then the lead wire connected to the information display module 11 may be connected to the power supply fixing terminal 13.

Or in some embodiments, wires may be preformed on the power supply fixing terminals 13, and the power supply fixing terminals 13 are fixed to the housing 10 after the wires are electrically connected with the information display module 11. Or in a preferred embodiment of the present invention, the metal conductive member 16 may be embedded at the housing 10. Specifically, as shown in fig. 6, a groove 15 for accommodating the power supply fixing terminal 13 is disposed at a position of the casing 10 near the side wall, the power supply fixing terminal 13 is disposed in the groove 15, a metal conductive member 16 electrically connected to the power supply fixing terminal 13 is disposed at the side wall of the groove 15, and the information display module 11 is electrically connected to the conductive rope 2 through the power supply fixing terminal 13 after passing through the metal conductive member 16. The fixing structure of the power supply fixing terminal 13 on the left side in fig. 6 is the same as the fixing structure of the power supply fixing terminal 13 on the upper side, the structure in which the power supply fixing terminal 13 is not yet incorporated is on the right side, and the structure in which the power supply fixing terminal 13 is already incorporated is on the upper side. Thus, by means of different design, the state of the power supply fixing terminal 13 when it is fitted into the recess can be known.

The metal conductive member 16 may be pre-embedded in the housing 10 by injection molding or by providing a conductive sheet groove on the housing 10 and then placing the metal conductive member 16 in the conductive sheet groove, thereby realizing that the metal conductive member 16 is placed on the side wall of the groove 15. An end of the metal conductive member 16 remote from the recess 15 may be disposed on the housing 10 outside the recess 15 and exposed, so that electrical connection with the metal conductive member 16 is facilitated through the exposed end. When the information display module 11 is connected to the metal conductive member 16, a screw connection or welding may be used as long as an electrical connection is formed. In this way, when the power supply fixing terminal 13 is placed in the groove 15, the side wall of the power supply fixing terminal 13 is electrically connected with the metal conductive piece 16, and at the moment, the current on the conductive rope 2 flows to the metal conductive piece 16 and then flows to the information display module 11 through the power supply fixing terminal 13, so that the external power supply on the conductive rope 2 can supply power to the information display module 11 or other modules in the information board 1. According to the embodiment, through the mode of arranging the metal conductive piece 16 in the groove 15, the fixed connection of the power supply fixed terminal 13 arranged in the groove 15 and the electric connection of the power supply fixed terminal 13 and the metal conductive piece 16 can be simultaneously realized, the step of independently and electrically connecting the power supply fixed terminal 13 and the metal conductive piece 16 is omitted, the installation step is simplified, and the assembly efficiency is improved.

Preferably, the power supply fixing terminal 13 is cylindrical, and the diameter of the ring wing 132 is larger than that of the through hole 121. In some embodiments, the power supply fixing terminal 13 may be directly disposed in the interior of the housing 10, and then the terminal inner hole 130 of the power supply fixing terminal 13 may be aligned with the threading tube 120 of the threading through hole 121, so long as the fixing of the power supply fixing terminal 13 and the threading of the conductive rope 2 can be achieved. If the casing 10 between one end of the threading tube 120 and the threading through hole 121 is provided with a threaded hole, the axis of the threaded hole is perpendicular to the inner surface of the casing 10, the power supply fixing terminal 13 may be a cylindrical metal piece with a peripheral thread, the terminal inner hole 130 penetrating through the central axis is provided on the peripheral side wall of the power supply fixing terminal 13, and then when the power supply fixing terminal 13 is screwed into the threaded hole, the terminal inner hole 130, the threading tube 120 and the threading through hole 121 are on the same straight line, so that the protrusion of the power supply fixing terminal 13 to the outside of the casing 10 can be avoided, and the appearance is more attractive.

In the present invention, the fastener 131 in the power supply fixing terminal 13 plays an important role, and is an important part in achieving fixing and electrical connection in the power supply fixing terminal 13. In some embodiments, as shown in fig. 8, fig. 8 shows a simple embodiment of the fastener 131 in the power supply fixing terminal 13. The fastener 131 may be a screw which is then threaded into the sidewall of the power fixing terminal 13, the screw being disposed in the threaded hole, the screw facing the terminal inner hole 130. When the conductive rope is installed, the screw is firstly rotated to loosen the screw, the conductive rope 2 passes through the terminal inner hole 130, and then the screw is screwed, so that the screw can fix the conductive rope 2 and realize electric connection with the conductive rope 2. In the embodiment where the fastener 131 is a screw, the screw is protruded to the outside of the case 10 in order to achieve tightening of the screw. In the embodiment in which the power supply fixing terminal 13 is disposed inside the housing 10, the screw of the power supply fixing terminal 13 may be further disposed inside the housing 10, and then the back of the housing 10 may be perforated at the screw position of the power supply fixing terminal 13, and then the screw may be rotated after being extended into the perforated by a tool such as a screwdriver, so as to fasten or unfasten the fastener 131. In some embodiments where the sign 1 is a display screen on both sides, it is not possible to open a hole in the back of the housing 10, and if a screw scheme is used, the screw is typically protruded outside the housing 10 to facilitate the screw tightening operation.

The above-mentioned scheme of fastening member 131 is screw, and it is relatively troublesome to use tools such as a screwdriver for fastening. In this embodiment, the fastening may be performed by using an elastic member and a pressing manner. Further, as shown in fig. 9 to 11, the fastening member 131 is an elastic fastening member 133, a push rod 134 is disposed in the power supply fixing terminal 13, the push rod 134 abuts against the elastic fastening member 133, and the elastic fastening member 133 releases the fixing state with the conductive rope 2 when the push rod 134 is pressed. In a normal state, i.e., when the push rod 134 is not pressed, the elastic fastener 133 presses the conductive cord 2 under the action of its own elastic force, and if there is no conductive cord 2, the elastic fastener 133 occupies a part of the space of the terminal inner hole 130. When the conductive rope 2 is placed in the terminal inner hole 130, the elastic fastener 133 will abut against the conductive rope 2 and press the conductive rope 2, so that the conductive rope 2 and the elastic fastener 133 are tightly pressed to be fastened, as shown in fig. 10. When the push rod 134 is pressed, as shown in fig. 11, since the push rod 134 abuts against the elastic fastening member 133, the bottom of the push rod 134 pushes the elastic fastening member 133 to move away from the conductive rope 2, and the elastic fastening member 133 releases the abutting state with the conductive rope 2, thereby releasing the conductive rope 2, i.e., releasing the fixing state with the conductive rope 2. The conductive cord 2 may be withdrawn or moved from the terminal bore 130 at this point. When the conductive rope 2 needs to be fixed in the terminal inner hole 130 again, the pushing rod 134 is only required to be released, and the elastic fastener 133 presses the conductive rope 2 under the action of self elastic force, so that fastening and electric connection are realized. The conductive rope 2 can be fastened and released by pressing the pushing rod by hand, and additional tools are not needed, so that the fixing and adjustment of the metal rope and the information board 1 are greatly facilitated.

The elastic force of the elastic fastener 133 may be self elastic force or may be formed by a spring. If the elastic fastener 133 includes a pressing block and a spring, the spring presses the pressing block against the conductive rope 2 by the action of elastic force to fasten with the conductive rope 2. In an embodiment in which the elastic force of the elastic fastener 133 is self elastic, as shown in fig. 9 to 11, the elastic fastener 133 may be an elastic bending piece, one end of the elastic bending piece is fixed inside the power supply fixing terminal 13, the other end is used for pressing the conductive rope 2, the pushing rod 134 is in a circular cylindrical shape, the pushing rod 134 and the terminal inner hole 130 of the power supply fixing terminal 13 are on the same axis, and when the pushing rod 134 is pressed, the elastic bending piece is separated from the conductive rope 2, so that fastening and separation can be achieved through one elastic bending piece, and the structure is simple. In order to avoid the push rod 134 from falling out of the power supply fixed terminal 13, the structure of one end of the push rod 134 inside the power supply fixed terminal 13 is set larger, so that the larger end can clamp the side wall of the power supply fixed terminal 13, and the push rod 134 is prevented from falling out. In this embodiment, by adopting the circular cylindrical push rod 134, the conductive rope 2 can pass through the push rod 134, and the space occupied by the push rod 134 is surrounded on the push rod 134, so that the occupied space is relatively small and attractive.

In order to facilitate connection of the conductive ropes 2 up and down or left and right, the information board 1 is generally rectangular, further, four conductive rope channels 12 are arranged in parallel, two of the conductive rope channels are arranged in parallel transversely, the other two conductive rope channels are arranged in parallel longitudinally, cross guide grooves 19 are formed in the intersections of the conductive rope channels 12, a guide cover plate 20 is arranged at the top of each cross guide groove 19, a threading pipe 120 is arranged between the two cross guide grooves 19, and one end of the threading pipe 120 is covered by the guide cover plate 20. The four ends of the cross guide groove 19 are all provided with arc-shaped guide openings, the cross guide groove 19 comprises two crossed guide grooves, and the guide groove of each cross guide groove 19, the threading pipe 120 and the threading through hole 121 in the same direction form a conductive rope channel 12. Thus, through the cross-shaped guide groove 19, the conductive thread 2 can penetrate the conductive thread channel 12 transversely or penetrate the conductive thread channel 12 longitudinally. The cross guide groove 19 can be used as a closed space through the guide cover plate 20, so that the conductive rope 2 is limited in the cross guide groove 19, and the rope can be threaded conveniently and smoothly. Meanwhile, the guide cover plate 20 can fix the threading pipe 120 in the shell 10, so that the threading pipe 120 is fixed, and multiple functions of the guide cover plate 20 are realized. The guide cover plate may be fixed on the housing 10 by sticking, screwing or clamping the guide cover plate on the housing 10, for example, in the embodiment of the present invention, a plurality of ribs 21 (which may also be ribs or side walls of a threading tube slot) are disposed on the periphery of the guide cover plate 20 inside the housing 10, so that the guide cover plate 20 is pressed between the ribs 21, and the side walls of the ribs 21 will prop against the guide cover plate 20. The guide cover plate is prevented from falling off, and the guide cover plate is fixed inside the shell. Through the cross guide slot, a transverse conductive rope channel and a longitudinal conductive rope channel can be realized, so that when the position of the conductive rope is not moving, the transverse suspension or the longitudinal suspension of the information board 1 can be realized, and different information display requirements are met.

In all the above embodiments, the information display module 11 is not specifically limited, and the key of the present invention is to facilitate connection and fixing, so long as information display and power supply can be performed. For example, the information display module 11 may be a planar printed matter and an electric light source, and the electric light source illuminates the planar printed matter to realize information display. The connection of the electric light source power supply and the information board 1 can also be realized through the conductive rope 2 and the power supply fixing terminal 13.

Wherein the connection can be made directly if the power supply 3 to which the conductive cord 2 is connected is of the same supply voltage and polarity as required by the electronic display and the processor. If the voltages are different or the polarities are different, rectification can be performed through a rectification module (such as a rectification bridge), the rectification module can convert alternating current or direct current with uncertain positive and negative poles into voltage with determined positive and negative poles, then the output positive pole of the rectification module is connected with the positive pole of the input end of the power supply unit, and the output negative pole of the rectification module is connected with the negative pole of the input end of the power supply unit, so that power supply to the power supply unit is realized. The power supply unit (such as a DC-DC voltage conversion unit, an LDO linear voltage stabilizing unit and the like) is used for carrying out voltage conversion and voltage stabilization, providing proper voltage for the processor and the electronic display screen, and the processor is used for sending information (including text information, picture information or video information and the like) to be displayed to the electronic display screen for display and display.

Of course, the storage battery (such as a lithium battery) can be arranged in the information board 1, and the charging of the storage battery and the power supply to the internal unit can be realized through the power supply fixing terminal 13, so that the information board 1 can also work normally when the external power supply 3 is powered off.
