[0002]
[Prior art]
In general, many electrical / electronic measuring devices have harnessed wiring, sampling piping, operation piping, etc. applied in a complicated manner. Therefore, for example, as shown in FIG. 7, the wirings e, f,... And the pipes g, h,... Are made using the gaps and spaces between the devices a, b, c, d provided in the main body case (not shown). I was drawing around. Further, in order to suppress the generation of noise that affects the analysis value and the measurement value, the shield tape i may be wound around the main wiring. In the figure, symbol j is a base plate, k is a frame standing on the base plate j, and a body case (not shown) is attached to the frame k.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional electric / electronic measuring devices, the internal space is extremely narrow due to compactness, etc., so that the wiring and piping are complicated, damaged or crushed due to the influence of dense equipment layout. There was also.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the wiring / pipe structure of the analysis / measurement apparatus of the present invention will be described below in detail with reference to the drawings.
FIGS. 1 to 3 show an embodiment in which the sides and bottom of the main body case of the analyzer is a double structure, 1 main body case, 2 a base plate, 21 is rubber feet attached to the base plate 2 , 3 and 4 are inner plates erected on both sides of the base plate 2, 5 is a rear plate, and 6 is a frame comprising an upper frame 61 and front frames 62 and 62.
[0009]
7 the side plates before they are assembled by screws or the like before unit frame 62, 8,9 are assembled by screws or the like from the outside to the inner plates 3 and 4, each other engaged upper end edge on the upper frame 61 Spaces 10 and 11 for wiring and piping are formed between the inner plates 3 and 4. Reference numeral 12 denotes a bottom plate which is assembled to the bottom surface of the base plate 2 with screws r or the like , and a space 13 for wiring and piping storage is formed between the base plate 2 and the base plate 2. w is wiring, p is piping, 14 is a relay, and 15 to 19 are devices assembled to the base plate 2 and the inner plates 3 and 4.
[0010]
Wherein the base plate 2 and the inner plate 3 and 4, apertures 22～25,31～34,41～45 each wiring and piping is opened, the space wires w and pipe p from the inside 10, 11, 13 So that they can be led together. The outer plate 8 is formed with an inspection opening 82 covered with a detachable lid 81 with screws or the like to facilitate maintenance work. The other outer plate 9 is also provided with a similar lid 91 (not shown).
[0011]
Further, it is preferable to attach a shield finger s for preventing howling to the bottom plate 12 (see FIGS. 4A and 4B). 4A is made of an elastic sheet metal material, and its base portion s ₁ is fixed to the inner surface of the bottom plate 12 with a rivet or an adhesive, and the curved portion s ₂ at the tip thereof is the bottom surface of the base plate 2. It is comprised so that it may urge-contact to. In FIG. 4B, a pair of elastic synthetic rubbers s ₃ and s ₃ are connected by metal ribs s ₄ and s ₄ , and one synthetic rubber s ₃ is attached to the base plate 2 with a magic tape s ₅ . The other synthetic rubber s ₃ is adhered to the bottom surface and urged against the inner surface of the bottom plate 12.
[0012]
In the main body case 1 configured as described above , in particular, by providing the three spaces 10, 11, and 13 for wiring and piping, first, the wiring w is introduced into the spaces 10 , 11 , and 13 , respectively. Thus, it is not necessary to make a harness separately, and it is not particularly troublesome to install. Each of these spaces is prepared in advance, and it is possible to construct the wiring w and the piping p in advance, and it is easy to avoid those that dislike mixed line and living together. In particular, the length of the wiring w is long. Can be processed relatively coarsely, and wiring and piping work becomes extremely easy.
[0013]
In addition, the degree of freedom of layout of the devices 15 to 19 is improved, and a coherent arrangement is possible, and the occurrence of troubles such as disconnection and breakage due to excessive living of the devices 15 to 19 and the wiring w / pipe p is avoided. And an orderly and confusing internal structure can be formed. In addition, the bottom plate 12 can be provided within the height of the rubber feet 21, so that the bottom space 13 can be effectively used, and the size can be reduced.
[0014]
And each double structure effectively prevents intrusion of disturbing elements that cause noise and leakage of the disturbing elements to the outside, and analysis without requiring troublesome winding of shield tape The reliability of values and measurement values can be improved. Further, by separating the AC wiring w and the DC wiring w in the spaces 10 , 11 , and 13 , the influence of noise from the AC wiring w can be reduced.
[0015]
Further, even in the case where there are vibrations and sounds as the ambient conditions, these can be effectively absorbed by each double structure, and howling can be prevented. For the prevention of the howling, it is effective to use the shield finger s described above (see FIG. 4). Needless to say, the shield finger s is not limited to be provided between the base plate 2 and the bottom plate 12 but may be provided between the inner plates 3 and 4 and the outer plates 8 and 9.
[0016]
On the other hand, during maintenance, inspection of the wiring w / pipe p is extremely easy and reliable by removing the lids 81 and 91 of the outer plates 8 and 9, or by removing the bottom plate 12 with the body case 1 lying down. Can be done. Further, even when these replacements are required, the replacement work can be performed very easily without being interfered by the devices 15 to 19.
[0017]
5A and 5B show different embodiments in which only the bottom portion of the case body 1 has a double structure. In this case, rubber feet 2 1 are provided at the four corners of the bottom plate 12 attached to the base plate 2 with screws r or the like . foot hole 12 1 for passing the provided by efficient use of the bottom space, thereby achieving an even more compact. When the case main body 1 is relatively small, it can be sufficiently dealt with only by the double structure at the bottom.
[0018]
FIGS. 6A and 6B show another embodiment. In this case, a cartridge 120 for wiring and piping is detachably provided on the bottom of the main body case 1. The cartridge 120 stores the wiring w in the internal space 130 and is provided with connectors 121 to 125 at the connection ends. The connectors 121 to 125 are provided on the bottom surface of the base plate 2 of the main body case 1. By connecting to the connectors 221 to 225 and fixing the four corners to the base plate 2 with screws r, it can be integrated with the main body case 1. During maintenance, the cartridge 120 is removed by removing the screws r. can be easily detached, it is sometimes trouble occurs, it is possible to easily carry out maintenance by replacement of the cartridge 120. Needless to say, the cartridge 120 is not limited to the bottom, but may be attached to a side portion (an inner plate or the like) of the main body case 1.
