A rear housing; a terminal unit that is inserted into the rear housing and mounts at least terminals and light emitting diodes on the board; and a rear part. It is characterized by comprising a front housing having a light emitting diode insertion portion into which a light emitting diode is inserted by being fitted and locked in the housing.

In order to achieve the above second object, the present invention provides the indicator structure according to claim 1, wherein a partition wall is formed inside the housing body of the rear housing, and the partition wall is formed on the surface side of the partition wall. The partition forms a plurality of terminal insertion parts, the lower part of the partition has a mating surface that is one step lower, and the terminal mounted on the mounting surface of the board of the terminal unit has a cantilevered contact part and this contact part. A presser part formed on the front side is formed, and when the front housing is fitted and locked to the housing body of the front housing, it is fitted to the fitting surface part of the front part of the partition of the rear housing. It is characterized in that a terminal pressing portion for pressing the terminal pressing portion inserted into the terminal insertion portion is formed.

[0008]

[Action]

 According to the structure of claim 1, by inserting the terminal unit into the rear housing, inserting each terminal into the terminal inserting portion to mount the terminal unit in the rear housing, and mounting the front housing in the rear housing, the indicator casing is installed. Can be assembled, and the assembly becomes easy.

According to the configuration of claim 2, when the terminal unit is inserted into the rear housing and each terminal is inserted into the terminal insertion portion and the terminal unit is mounted in the rear housing, the contact portion of the terminal is located closer than the end surface of the partition. It protrudes outward and the terminal retainer protrudes outwards from the mating surface.However, when the front housing is installed in the rear housing, the terminal retainer of the front housing is aligned with the mating surface of the partition. It is possible to fit and press the pressing portion of the terminal to compress the terminal so that the protruding height h of the contact portion of each terminal is the same.

Therefore, the terminals are not compressed when the terminal unit is assembled to the rear housing, and the terminals can be aligned by compressing the terminals when the front housing is assembled to the rear housing and the final assembly. It is possible to prevent the terminal spring from sagging without compressing the terminal in advance.
