As described in Japanese Patent No. 9590, a structure is adopted in which each component of the timer mechanism is sequentially attached to a board housed and fixed in a switch case, and this board is housed in the case and fixed with screws K.

[Problems with background technology]

This type of structure in which the board with the timer mechanism attached is housed in a case and fixed with screws takes time and effort to assemble, and also requires a narrow space for the assembly and fixing operation.
The case is large, and since the timer mechanism, terminal mechanism, etc. are integrally assembled on the board, it is difficult to improve assembly accuracy.

[Object of the Invention] The present invention has been made in view of the above-mentioned drawbacks, and it is possible to easily incorporate a timer unit, to ensure that the timer is stored and held in the storage recess without rattling, to facilitate miniaturization, and to improve the assembly accuracy of the timer. The present invention provides a timer switch which can improve the terminal connection workability and improve the terminal connection workability.

[Summary of the invention]

The present invention is such that a timer unit and a terminal unit can be stored by falling into respective storage recesses of a case member, and at least one case member has two storage recesses formed in the center and on both ends. It comprises a split case member, a timer unit that is dropped and stored in a storage recess at the center of the case member, and a terminal unit that is dropped and stored in the storage recesses on both ends of the case member, and a The storage recesses are formed deeper than the four storage sections on both ends, and the boundaries between the storage recesses at both ends are stepped portions on the side wall of one case member, and the one case member is sandwiched between the pair of step portions. A concave groove portion is formed that continues from the opening edge to the central storage concave portion.

〔Effect of the invention〕

According to the present invention, the housing recess for the timer unit is formed in the center of one case member of the two-split case, and the housing recess for the terminal unit is formed at both ends, and the housing recesses at both ends are formed on the side wall of this case member. Since the boundary with the central storage recess is a stepped portion, a recessed groove portion is formed which is sandwiched between the pair of stepped portions and continues from the opening edge of the case to the timer unit storage recessed portion, so that the recessed groove portion of one case member serves as a guide. As a result, the timer unit can be easily stored, and the timer unit can be held in its proper position without wobbling due to the recessed groove, and its operation can be maintained reliably. Storage port B(s
Since there is no partition between the terminal unit and the timer unit, terminal connections can be made at the top, making it easier to operate.Also, there is no partition in the direction in which the terminal unit and timer unit are lined up, making it possible to reduce the size and make the timer unit smaller. The mechanisms can be assembled separately, improving the precision of assembling the timer mechanism, and since the case member is deep only in the four storage areas at the center, the lower surfaces of the storage recesses at both ends are made thinner, thereby saving on materials. be able to.
