In particular, the upper side and the lower side of the front panel are respectively provided with an extension space, and the extension spaces are respectively used for accommodating an upper wiring terminal combination and a lower wiring terminal combination. Through the setting of above structure, go up binding post combination, lower binding post combination and hold in the extension space of front panel for the interface of whole product presents streamedly, and the product is elegant appearance more.

Specially, the two sides of the space for accommodating the upper wiring terminal combination and the lower wiring terminal combination are respectively provided with a convex rib, and the convex ribs are used for forming interference fit with the upper wiring terminal combination and the lower wiring terminal combination. Through the setting of above structure for go up binding post combination, lower binding post combination more firm in the position that extends the space, can not be because of when the outside wiring of operation, move the position of inside binding post combination, lower binding post combination, arouse the off normal in outside wiring hole.
