Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-4, the present invention provides an embodiment: a shell for a time relay comprises a shell 1 inserted on an AH3-3 time relay base, wherein the upper surface of the shell 1 is provided with a round hole 2 for a relay stud to be inserted conveniently; two lamp holders 4 for mounting LED lamps are further arranged inside the shell 1, and the lamp holders 4 and the round holes 2 are on the same surface; the bottom of the shell 1 is also provided with two slots 3 which are used for being connected with the relay base in an adaptive mode, and the number of the slots 3 is two and the two slots are respectively arranged on two opposite surfaces of the shell 1.
