Problems solved by technology

However, the main unit of the AC contactor whose control circuit is DC can only install the top auxiliary contact module, and cannot install the side module. Therefore, due to the limited space size of some installation cabinets, it is impossible to install the DC control circuit AC with the side auxiliary contact module. contactor

Embodiment Construction

[0013] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0014] Such as figure 1 , 2 , 3, on the base shell 1 of the DC control circuit AC contactor, on the front and rear shell walls of the long side part of the interface combined with the base shell 3, the distance from the long side part of the interface is convex downward 20 centimeters on both sides of the central line of the part is an upward recessed gap 2 with a width of 5 centimeters and a depth of 6 centimeters at the central line. On the front and rear shell walls of the recessed part corresponding to the interface combined with the base shell 1 on the base shell 3 and the downward protruding part on the base shell 1, the distance from the interface is recessed downward. There is a downward recessed gap 4 with a width of 5 cm and a depth of 12 c...

Abstract

The invention relates to a DC control loop AC contactor capable of allowing a side auxiliary contact module to be mounted. The DC control loop AC contactor comprises an AC contactor host base housingand a bottom base housing. The front and back housing walls of a long edge portion of an interface, combined with the bottom base housing, in the base housing are respectively provided with a 5*6 cm upward-concave gap, the center line of which is 20 centimeters away from the center line of a downward-projection portion respectively. The front and back housing walls of a recess portion, corresponding to the downward-projection portion of the base housing, of the bottom base housing are respectively provided with a 5*12 cm downward-concave gap, the center line of which is 20 centimeters away from the center line of a downward-concave portion respectively. The DC control loop AC contactor can realize mounting of the side auxiliary contact module to the AC contactor of a DC control loop; the side auxiliary contact is simple and feasible in installation operation and convenient to dismount; and the side auxiliary contact is adopted to replace a top auxiliary contact, thereby reducing heightof a product after assembly, saving space of an installation cabinet in width and bringing great convenience for users in cost saving.

Description

technical field [0001] The invention belongs to an AC contactor, in particular to a DC control circuit AC contactor capable of installing side auxiliary contact modules. Background technique [0002] The functions of the currently known auxiliary contacts of AC contactors are to realize the functions of self-locking, interlocking, signal control, and linkage control of the main circuit. The AC contactor auxiliary contact module can be divided into top module and side module according to the installation form. Users can choose the number of auxiliary contacts and the installation form of auxiliary contacts according to the use requirements and the space size of the installation cabinet. The control loop of the same rated current is DC. The number of turns of the AC contactor coil is about a thousand more than that of the AC coil. It is necessary to increase the height of the coil frame without changing the length and width of the coil frame, which also increases The overall ...
