Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a carrying case of a measuring instrument, and more specifically, to improvement of operability of the measuring instrument in a state where the measuring instrument is stored. .

<Conventional Technology> FIGS. 3A and 3B show an insulation resistance meter as an example of a portable measuring instrument, wherein FIG. 3A is a top view and FIG. 3B is a bottom view. In the figure, a display unit 1, a measurement switch 2, and a measurement range changeover switch 3 are provided on the upper surface. And
Plugs 4a, 4b formed in substantially L-shape at both ends of the lower surface
Are provided with connectors 5a and 5b into and out of which a battery housing 7 having an openable / closable lid 6 is provided between the connectors 5a and 5b.
Is provided.

FIG. 4 is a structural explanatory view showing an example of a conventional carrying case accommodating the measuring instrument shown in FIG. In the figure, a first lid 8 which can be opened and closed so as to expose the entire surface of the measuring instrument is hinged on the upper surface, and the lower surface is closed, and each corner 9a, 9b corresponding to the connector 5a, 5b is a plug 4a. , 4b are cut out so that they can be inserted and removed.

FIG. 5 is an explanatory view of a use state in which the measuring device of FIG. 3 is housed in the carrying case of FIG. In use,
The plugs 4a and 4b are inserted into connectors exposed from holes formed by cutting out the corners 9a and 9b of the carrying case, and the cover 8 is opened to expose the entire surface of the measuring instrument.

<Problem to be solved by the invention> However, in such a conventional configuration, the connectors 4a and 4b are easily pulled out, which is not preferable in terms of work efficiency and safety.

When replacing the battery, the measuring instrument must be taken out of the carrying case, resulting in poor operability.

There is such a problem.

The present invention focuses on such problems.
An object of the present invention is to provide a carrying case of a measuring instrument having a function of preventing a connector from being detached and allowing battery replacement while the measuring instrument is housed.

<Means for Solving the Problems> The present invention for solving such a problem includes a connector in which an operation unit and a display unit are provided on an upper surface, and a plug formed into a substantially L-shape at both ends of the lower surface is inserted and removed. A carrying case for accommodating a measuring instrument provided with a battery accommodating portion having an openable / closable lid between these connectors, wherein a first opening / closing means is provided on an upper surface so as to expose the entire surface of the measuring instrument. The lid is hinged, and a second lid that can be opened and closed to expose a connector on the lower surface of the measuring instrument and the battery housing is hinged to the lower surface, and the plug is attached to both side surfaces at both ends. It is characterized in that a notch for drawing out in a substantially right angle direction is provided.

<Operation> In the measurement state, the second lid of the carrying case presses the plug toward the connector, and functions as a retaining mechanism.

Then, when replacing the battery, the second lid of the carrying case may be opened to expose the battery housing, and the battery can be replaced without removing the measuring instrument from the carrying case.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a structural explanatory view showing an embodiment of the present invention.
In the figure, a first lid 10 that can be opened and closed so as to expose the entire surface of the measuring instrument is hinged to the upper surface as in the conventional case. On the other hand, the openable and closable second lid 11 for exposing the connector and battery housing on the lower surface of the measuring instrument is hinged to the lower surface, and the plug is attached to both ends of the side in a direction substantially perpendicular to both sides. Notches 12a, 12 for pulling out
b is provided. Hooks 14a, 14b and 15a, 15b are connected to each other to close the second lid 11.

FIG. 2 is an explanatory view of a state in which the measuring device of FIG. 3 is housed in the carrying case of FIG. 1, wherein (a) shows a measuring state and (b) shows a battery replacement state.

In the measurement, the second lid 11 of the carrying case is opened to expose the connectors 5a and 5b, and after inserting the plugs 4a and 4b, the second lid 11 is closed. (A) shows this state.

When replacing the battery, as shown in (b), the second lid 11 is opened with the measuring instrument stored in the carrying case to expose the battery storage section 7, and the lid 6 is removed.

With this configuration, in the measurement state,
The second lid 11 of the carrying case presses the L-shaped plugs 4a, 4b in the direction of the connectors 5a, 5b, thereby preventing the plugs 4a, 4b from coming off.

When the battery is replaced, the second lid 11 of the carrying case is kept in a state where the measuring instrument is stored in the carrying case.
It is only necessary to open the battery compartment to expose the battery compartment, and it is not necessary to take the measuring instrument in and out as in the prior art.

Although the example of the insulation resistance meter has been described in the above embodiment,
It is also suitable as a carrying case for other measuring instruments having the same structure.

<Effects of the Invention> As described above, according to the present invention, it is possible to realize a carrying case of a measuring instrument having a function of preventing a connector from being detached and enabling battery replacement while the measuring instrument is housed. Is big.
