Description

[Technical Field]

[0001] The present invention relates to a display device connected to a weighing device main body. [Background technology]

[0002] In a separately installed display device connected to the weighing device main body, a cable terminal for connecting to the weighing device main body, a printer, a scanner, etc. is connected to a connector on the back of the display device. Therefore, when making a display device waterproof, a waterproof case is placed over the display device, a cable covered with a waterproof bushing is inserted into a through-hole on the back of the waterproof case, and the cable terminal is connected to the connector on the back of the display device.

[0003] Therefore, when the waterproof specification is made, the size of the display device becomes larger, and when the display device is placed directly on a workbench, the occupied area of ​​the display device becomes larger, which causes a problem of worsening workability. Also, when the waterproof case is made smaller, the gap between the back of the waterproof case and the back of the display device becomes narrow, which causes a problem of time and effort being required to connect the cable terminal inserted into the waterproof case to the connector on the back of the display device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-76560 Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a new display device that solves these problems. [Means for solving the problem]

[0006] A display device according to one embodiment of the present invention includes: A display device having a display on the front and a housing for housing an electronic board connected directly or indirectly to the display on the rear, The electronic board is provided with a plurality of outlets into which a plurality of cables are individually inserted; an opening large enough for an operator's hand to enter to connect the cables to the outlets, and a lid for closing the opening, provided on a rear surface of the storage section; The cover portion is provided with a through hole for leading out the cable to the outside, The gist of the invention is that when the cable introduced into the storage section through the through hole is connected to the socket, the connection end of the cable is connected to the socket in a horizontal direction or in a state tilted from the horizontal direction.

[0007] A cable, fitted with, for example, a rubber bushing or grommet, is inserted through the through-hole in the lid, which is separated from the rear surface of the storage compartment, to close the through-hole. Then, a user reaches into the storage compartment through the opening and inserts the cable terminal into the receptacle. Since the cable is extended from the receptacle to the lid just long enough for the user's hand to fit through the opening, when the lid is placed over the opening to seal the storage compartment, the cable stored in the storage compartment changes from a hanging state to a state in which the cable terminal is connected to the receptacle horizontally or tilted from the horizontal. Therefore, even if water seeps into the storage compartment along the cable without waterproofing measures, the cable terminal is connected to the receptacle horizontally at a position higher than the lowest end of the cable, preventing water from entering the receptacle.

[0008] In one embodiment of the display device, an annular rib is provided on the inside of the lid portion to come into close contact with a gasket provided along the periphery of the opening.

[0009] When the lid is placed over the opening on the back of the storage unit, the ribs on the inside of the lid fit tightly against the gasket to seal the opening. Also, by inserting a cable fitted with a waterproof rubber bushing or grommet through the through-hole in the lid, the lid becomes waterproof, making the display device itself waterproof.

[0010] Furthermore, in one embodiment, the rib of the display device has a plurality of first reinforcing ribs provided around the entire circumference in a direction that intersects with the rib, and further, a portion of the first reinforcing ribs has second reinforcing ribs that are diagonal to the rib.

[0011] With this configuration, when the lid that closes the opening of the storage section is molded from, for example, ABS resin, the parts that tend to be weak can be reinforced with ribs, thereby increasing the sealing strength of the lid.

[0012] In one embodiment, the multiple sockets of the display device include a downward-facing socket, a horizontally facing socket, and a horizontally facing socket that is tilted toward the opening within a range of 1 to 10 degrees.

[0013] For example, a power outlet is inserted facing upward into a downward-facing socket. This prevents water from entering the power outlet even if the case is not waterproof and water seeps into the power cable. Furthermore, the cable connected to a horizontal socket is connected to the socket in a hanging state, preventing water from entering the horizontal socket. Additionally, the horizontal sockets are arranged in two rows, one at the front near the opening and one at the back far away. The back socket is tilted 1 to 10 degrees toward the opening, making it easier to connect the cable terminal to the socket in the lower row.

[0014] The opening into which the hand is inserted is, for example, approximately 8 cm in height and 16 cm in width, which is large enough to allow for easy connection of the cable terminal. [Effects of the Invention]

[0015] According to one embodiment of the present invention, a display device has an opening on the back of the storage compartment large enough to fit a hand. The user can insert their hand into the opening to connect a cable terminal to a socket inside the storage compartment, and then seal the opening with a lid through which the cable passes. Therefore, by waterproofing the through-hole through which the cable passes, the storage compartment can be made watertight. This eliminates the need to cover the display device with a waterproof cover, as in the past, allowing the display device to be made more compact. Furthermore, since the cable can be hung down inside the storage compartment and the cable terminal can be connected to a socket higher than the lowest end of the cable, even if water accidentally seeps into the storage compartment along the cable when the display device is not waterproof, water can be prevented from entering the socket.

DETAILED DESCRIPTION OF THE INVENTION

[0017] An embodiment of the present invention will be described below with reference to the drawings. However, this embodiment does not limit the technical scope of the present invention. In the drawings, identical or similar parts are denoted by the same or similar reference numerals. However, the drawings are schematic, and the dimensional ratios and the like differ from those of the actual parts. In this specification and drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals, and elements not directly related to the present invention are not shown.

[0018] FIG. 1 shows a perspective view of a display device 100 according to one embodiment. This display device 100 is a separate display device for a weighing device (not shown) and is typically placed on a workbench with the display 1 facing diagonally upward, as shown in FIG. 1. Therefore, the bottom surface 10 of the storage compartment 3 is shaped to be inclined diagonally relative to the display 1. Alternatively, as shown in FIG. 2, the bottom surface 10 of the display device 100 may be attached to the top of a stand S. In this case, a torque hinge H is attached between the top and bottom surface 10 of the stand S, allowing the display 1 to be fixed at any desired tilt angle. Therefore, as shown in FIG. 3, cables C are drawn out from the back of the display device 100 to connect to the weighing device, a network, a scanner, a printer, and even computers and peripheral devices.

[0019] As shown in FIGS. 1 to 3 , the display device 100 is composed of a front case FC and a rear case RC made of ABS resin, which are tightly secured together with screws SC via a gasket (not shown). A display 1 is attached in a watertight manner to the inside front surface of the front case FC, and an electronic board 3 connected directly or indirectly to the display 1 is housed in a storage section 2 constituting the rear case RC, as shown in FIGS. 6 and 7 . The electronic board 3 is also equipped with multiple sockets 4, and cables C connected to the sockets 4 can be inserted and removed through an opening 5 formed on the back surface of the storage section 2. Specifically, the opening 5 is approximately 8 cm long and 16 cm wide, allowing an operator to reach through the opening 5 and insert the terminals of the cables C into the sockets 5.

[0020] The opening 5 of the storage section 2 through which the cable C is pulled out is closed by the lid section 7 shown in Figures 3 and 5, but a second opening 70 is provided in the center of this lid section 7 to allow the cable C to pass through, and this second opening 70 is further closed by a grommet mounting frame 71 shown in Figures 3 and 4.

[0021] The grommet mounting frame 71 is configured to mount a plurality of rectangular grommets 72 (10 in FIG. 3) as shown in FIG. 3, as shown on the right side of FIG. 4, and is composed of a lower mounting frame 71a having five cutout portions 73 into which the grommets 72 are inserted, and an upper mounting frame 71b which holds down the grommets 72 mounted in the cutout portions 73 from above and is fixed to the lower mounting frame 71a with hexagon socket bolts 74.

[0022] This grommet 72 is waterproof. A through-hole 72a for inserting the cable C is provided in the center of the grommet 72, and the cable C can be inserted into the through-hole 72a by opening a cut portion 72b that is cut approximately in half. If the grommet 72 is not waterproof, a rubber plate with a slit for inserting the cable C may be used instead of the grommet mounting frame 71, and this may be placed over the opening 70 of the lid 7 to seal the opening 70.

[0023] As shown in Fig. 3, a stepped portion 75 for accommodating the grommet mounting frame 71 is provided on the front side of the lid portion 7, and with the grommet mounting frame 71 accommodated in the stepped portion 75, hexagon socket head bolts 77 are inserted into through holes 76 (see Fig. 4) at the four corners of the grommet mounting frame 71 and screwed into embedded nuts provided on the lid portion 7 to secure it in place. A rectangular frame-type gasket is inserted between the surface of the stepped portion 75 and the grommet mounting frame 71.

[0024] 5 shows the back side and left side surface of the lid 7, and the embedded nuts for fixing the grommet mounting frame 71 with bolts 77 are embedded in circular ribs 78 at the four corners provided on the outer periphery of the second opening 70 in Fig. 5. In addition, annular inner ribs 78a connecting the four circular ribs 78 act as reinforcing ribs when the grommet mounting frame 71 is tightly attached to the front side of the lid 7.

[0025] Additionally, on the outer periphery of this inner rib 78a, outer rib 78b surrounding the back peripheral edge 75a of step portion 75 that houses grommet mounting frame 71, a plurality of first reinforcing ribs 78c are provided at regular intervals in a direction that intersects with outer rib 78b, and further, second reinforcing ribs 78d that intersect diagonally with first reinforcing rib 78c are provided at locations located on the bottom surface 10 side of first reinforcing rib 78c. This configuration increases the crimping strength when attaching lid 7 to the back surface of storage section 2.

[0026] When attaching the lid 7 to the back surface of the storage section 2, a frame-shaped gasket shaped to fit the outer rib 78b in Fig. 5 is sandwiched between the lid 7 and the back surface of the storage section 2, and bolts are inserted from the front side into through holes 79 located near the four corners of the outer rib 78b and screwed into screw holes 20 provided on the back surface of the storage section 2 in Fig. 6 to secure the lid 7 and the storage section 2 together in a watertight manner.

[0027] 6 and 7, an electronic board 3 that is directly or indirectly connected to the display 1 is housed in the housing 2. This electronic board 3 is equipped with a plurality of sockets 4 into which a plurality of cables C are individually inserted.

[0028] Specifically, the sockets 4 include a downward-facing socket 40, a horizontally oriented socket 41, and a horizontally oriented socket 42 that faces sideways toward the opening 5 at an angle of 1 to 10 degrees. For example, a power cable terminal is inserted upward into the downward-facing socket 40. A cable C from, for example, the weighing device main body or a network is connected horizontally to the horizontally oriented socket 41 on the front side closer to the opening 5. Furthermore, a cable C from, for example, a computer or peripheral device is connected horizontally to the horizontally oriented socket 42 on the back side farther from the opening 5 and tilted toward the opening 5 at an angle of 1 to 10 degrees.

[0029] When connecting the terminal of cable C to each receptacle 4, the lid 7 is removed from the storage section 2, and the cable C is inserted through the through-hole of the lid 7, i.e., the through-hole 72a of the grommet 72 attached to the grommet mounting frame 71, as described above. At this time, the length from the grommet 72 to the cable C terminal is extended long enough so that a hand can be inserted through the opening 5 with the lid 7 removed. In this state, the user inserts the cable C terminal into the receptacle 4 by inserting the hand into the storage section 2. After the connection is complete, the lid 7 is placed over the opening 5 of the storage section 2 to seal it. At this time, the length of the cable C from the receptacle 4 to the lid 7 is extended long enough that a hand can fit through the opening 5, so the cable C stored in the storage section 2 is hanging down. Therefore, even if water seeps into the storage section 2 along the cable C, the terminal of the cable C is connected horizontally to the receptacle 4 at a position higher than the lowest end of the cable C, preventing water from seeping into the receptacle 4.

[0030] As described above, the cable C terminal is connected to the socket 4 horizontally inside the waterproof storage section 2, so there is no need to cover the display device with a waterproof cover as in the past, and the display device can therefore be made compact in size.

[0031] Although the present invention has been described in detail above using one embodiment, it is clear to those skilled in the art that the present invention is not limited to the embodiment described in this specification. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is illustrative and does not have any limiting meaning. [Explanation of symbols]
