SOLUTION: Shafts 11 and 11 are protrudingly provided at upper ends on both sides, and the shaft 11 is rotatably pivoted to a support portion 21 provided on the back surface of the indicating instrument, so that it does not hinder connection when connecting to a terminal. Pivot to the position.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a terminal cover of an indicating instrument rotatably supported by the indicating instrument.

[0002]

[Prior art]

 As shown in FIG. 4, a terminal cover 1 of a conventional indicating instrument is formed by molding a transparent resin plate into a substantially arc shape, and forming engagement recesses 2 and 2 at lower ends and engagement recesses 3 and 3 at arc portions. It is configured.

[0005] On the other hand, the indicating instrument 4 has support portions 5, 5 and 6.6 on its rear surface so as to surround terminals (not shown).

In order to fix the terminal cover 1 on the back of the indicating instrument 4 so as to cover the terminals, as shown in FIG. 4, engaging recesses 2, 2 provided at the lower end of the terminal cover 1 are supported. , 5 and the engaging recesses 3, 3 are fitted to the supporting portions 6, 6.

[0005]

[Problems to be solved by the invention]

 The terminal cover of the conventional indicator is detachable from the indicator, so when connecting to the terminal of the indicator, it is removed from the indicator, connected to the terminal, and attached again. Therefore, if the terminal cover removed from the indicating instrument during the wiring work is placed in an appropriate position without deciding the storage position, the removed terminal cover may be lost during the wiring work, resulting in a malfunction in the wiring work. There is a problem that will occur.

The present invention has been made in view of the above points, and has been given an instruction to prevent the terminal cover from being lost during the connection work by pivoting to a position that does not hinder the connection when connecting to the terminal. It is an object to provide a terminal cover for an instrument.

[0007]

[Means for Solving the Problems]

 The terminal cover of the indicating instrument of the present invention is a terminal cover that covers terminals arranged on the back of the indicating instrument. The terminal cover is movably pivoted and pivots to a position where it does not hinder the connection when connecting to the terminal, thereby preventing the terminal cover from being lost during the connection work.

By providing a notch adjacent to the terminal cover shaft, the terminal cover of the indicator of the present invention can be placed in a substantially vertical plane which does not hinder the connection when connecting the terminals.

[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a terminal cover 10 of an indicating instrument according to the present invention. The terminal cover 10 of the indicating instrument is made by molding a transparent resin plate into a substantially arc shape.

The terminal cover 10 has shafts 11, 11 protruding laterally at upper ends on both sides, notches 12, 12 formed below each shaft 11, and notches 13, 13 formed on both lower ends. Having.

On the other hand, as shown in FIG. 2, the indicating instrument 20 has upper supporting parts 21 and 21 and lower supporting parts 22 and 22 on the rear surface so as to surround terminals (not shown). A shaft hole 23 in which the shaft 11 is mounted is formed in the upper supporting portions 21 1 and 21. Lower support 6. 6 has a shape corresponding to the notch 13.

As shown in FIG. 3, the terminal cover 10 has a length a from the center of the shaft 11 to the notch 12 slightly smaller than a length b from the corner of the upper support 21 to the center of the shaft 11. It is set small. Therefore, when the terminal cover 10 is rotated in the direction of the arrow with respect to the upper support 21, the terminal cover 10 gets over the corner of the upper support 21 with resistance and stops at that position. It cannot return to its original position unless external force is applied.

Next, the operation will be described. As shown in FIG. 2, the terminal cover 10 is rotatably attached to the indicating instrument 20 by mounting the shafts 11 provided on both upper ends in shaft holes 23 provided in the upper support portions 21, 21.

When the terminal cover 10 is connected to the terminal of the indicating instrument, the terminal cover 10 is pivoted upward about a shaft hole formed in the supporting portions 21 and 21 to receive the resistance at the corners of the upper supporting portion 21. As a result, it is located in a substantially vertical plane indicated by a two-dot chain line in FIG. 2 and maintains the vertical position. Therefore, the terminal cover 10 does not hinder the connection when the terminals are connected.

After connecting the terminal cover 10 to the terminal of the indicating instrument, the terminal cover 10 is returned to the position indicated by the solid line in FIG. Is fixed to the position by locking the to the tip of the lower support portion 6.6.

[0016]

[Effect of the invention]

 As described above, according to the present invention, the shafts protruding from the upper ends on both sides are pivotally connected to the support provided on the back of the indicating instrument, and do not hinder the connection when connecting to the terminal. By turning to the position and returning to the original position after connecting to the terminal, it is possible to prevent loss during the connection work.
