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; may be mechanically, electrically or otherwise in communication with each other; they may be directly connected or indirectly connected through intervening media, or may be connected through the use of two elements or the interaction of two elements. 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 multifunctional alternating current contactor comprises a base 1 and a cover plate 4 movably connected with the base 1; after the cover plate 4 is connected with the base 1, the circuit connecting piece 2 is fixed between the cover plate 4 and the base 1; the circuit connector 2 comprises a first contact assembly 20 and a second contact assembly 21; the number of the first contact assemblies 20 is multiple, and the first contact assemblies are arranged on the base 1 side by side; the first contact assembly 20 comprises a movable contact rod 26 and a fixed contact rod 24 arranged at two ends of the movable contact rod 26, wherein the movable contact rod 26 is in a disconnected state with the fixed contact rod 24 at normal state; the second contact assembly 21 includes a movable contact plate 22 and stationary contact plates 23 disposed at two ends of the movable contact plate 22, and the movable contact plate 22 and the stationary contact plates 23 are in a closed state in a normal state.

To sum up, since the number of the first contact assemblies 20 is multiple, when the ac contactor is expanded, the ac contactor can be directly connected with the first contact assemblies 20 inside the apparatus, and therefore, it is not necessary to adopt a top-hanging accessory manner for hanging and expanding, and the problem that the height of the whole ac contactor product is increased due to the adoption of the top-hanging accessory is solved.

Meanwhile, the first contact assembly 20 is normally open, and the second contact assembly 21 is normally closed, so that the normally open circuit is generally used for self-locking circuit, and the normally closed circuit is generally used for interlocking circuit. Therefore, the equipment can be connected in a targeted manner according to the requirement of a control circuit, and the equipment can realize the self-locking or interlocking function.

On the basis of the above scheme, because the first contact assembly 20 and the second contact assembly 21 are both fixedly connected with the base 1 through the provided ferrule 25, a plurality of first contact assemblies 20 and second contact assemblies 21 can be fixed on the base 1 side by side, and stable operation of the two contact assemblies is ensured.

Furthermore, because the cover plate 4 is also provided with the protection piece 3, and the protection piece 3 is connected with the cover plate 4 to reduce the exposed area of the wiring terminal, the electric shock accident caused by the contact between a user and the wiring terminal can be avoided.
