That is, the utility model discloses a contact subassembly 1 has included two pairs of moving, static contact, and two sets of contact actuating mechanism separately-driven respectively two pairs move, the switching of static contact. When a product is in a problem or unexpected fault current occurs in a loop, and contacts of a relay are likely to be adhered, because two pairs of moving contacts and two pairs of static contacts are respectively and independently controlled by the corresponding driving mechanisms, even if one of the contacts is adhered, the main loop can be immediately disconnected, and normal work of equipment is prevented from being influenced. The utility model discloses only when two pairs move, the static contact adhesion takes place simultaneously, the talent leads to the main loop can not reliably break off, greatly reduced because the adhesion takes place unreliable risk.
Further, in order to improve the reliability of the utility model, the utility model can also be provided with a plurality of groups of contact assemblies 1, refer to fig. 1 again, take two groups of contact assemblies as an example, the static contact A12 of the two groups of contact assemblies is simultaneously arranged on one static contact end A21, and the static contact B14 of the two groups of contact assemblies is simultaneously arranged on the other static contact end B22; the moving contacts A11 and the moving contacts B13 of the two groups of contact assemblies are respectively and electrically connected through a flexible member 15. In order to realize the driving of the contact assemblies, two moving contacts A of the two groups of contact assemblies are simultaneously connected with a connecting piece of a moving contact driving mechanism A31, two moving contacts B of the two groups of contact assemblies are simultaneously connected with a connecting piece of a moving contact driving mechanism B32, namely, a contact pair on one side of the two groups of contact assemblies is driven to be opened and closed through an independent contact driving mechanism, a contact pair on the other side of the two groups of contact assemblies is driven to be opened and closed through an independent other contact driving mechanism, and thus, the two pairs of contacts of each group of contact assemblies can be independently controlled when being opened and closed.
As an embodiment of the present invention, the moving contact driving mechanism a31 includes a positioning member 311, a coil component 312, an armature 313, a connecting member 314, and a return spring 315, wherein the coil component 312 is fixed on an upper side surface of the positioning member 311; the upper end of the armature 313 is arranged outside one end surface of the coil component 312, the lower end of the armature 313 is bent in an L shape and then is arranged outside the lower side surface of the positioning piece 311 and is fixedly connected with one end of the connecting piece 314, and the middle part of the armature is rotatably connected with the end part of the positioning piece 311 to form a rotating fulcrum; the movable contact a11 is fixedly arranged at the other end of the connecting element 314, and two ends of the return spring 315 are respectively connected to the middle part of the armature 313 and the positioning element 311, so that the upper end of the armature 313 is far away from the coil assembly 312 when the coil assembly is powered off.

When the moving contact driving mechanism A31 works, the coil component is electrified, the magnetizer 3121 positioned in the center of the coil framework is magnetized to produce magnetic force, so that a suction force is produced to one end, namely the upper end, of the armature 313 close to the coil component, and because the middle part of the armature 313 is rotatably connected with the positioning piece 311, the armature 313 is driven to rotate around a rotating fulcrum of the positioning piece 311 under the action of the magnetic force of the magnetizer, so that the lower end of the armature 313 is driven to rotate clockwise in the figure, a connecting piece connected with the other end of the armature and a moving contact are driven to move, and the contact closing of the moving contact and a fixed contact is realized.
On the contrary, when the coil assembly is powered off, the armature 313 resets under the action of the return spring due to the loss of the magnetic force of the magnetizer 3121, and drives the moving contact and the fixed contact to be far away, so that the disconnection of the contact assembly is realized.
The moving contact driving mechanism B32 has the same structure as the moving contact driving mechanism a31, and is not described herein again. Of course, the moving contact driving mechanism B32 may also adopt other structural components capable of achieving the relative function, and the present invention is not limited in particular.
In addition, need to explain, the utility model discloses a connect through the flexible piece electricity between the moving contact, this flexible piece can adopt copper conductor or other to have flexible electric conductors, does not do specifically to restrict here, as long as can reach the function can.
Therefore, the utility model discloses a set up at least a set of contact subassembly to set up two sets of contact actuating mechanism simultaneously, be used for the two pairs of rigid contact group of a set of contact subassembly of independent control, and connect through the flexure between the movable contact between the two pairs of rigid contact group. When the actuation of contact, release action take place, if the jamming has appeared to single contact, then can not influence the action of another contact pair, another contact group throws the action that can be reliable promptly. Or a single contact group and a contact driving mechanism are in failure, the product can still realize partial functions, complete failure cannot be caused, and the reliability of the product is improved.
