Background
The ABCN phase contacts of the low-voltage switch product are normally opened and closed simultaneously, so that the power sources and the action structures of the contacts of all phases are basically consistent. However, when the product needs to realize some special functions, such as the neutral line overlapping function of a dual-power supply product, the N-phase contact and other phase contacts are not switched on or off simultaneously, and the action structures of all the N-phase contacts are different from those of other phases. Particularly, in a frame-type dual-power product with overlapped neutral lines, the most common way at present is to provide the opening power of the N-phase contact by using the opening spring, so that the installation way of the opening spring determines the high efficiency and the reliability of the opening action of the N-phase contact.
The N-phase contact spring of the existing neutral line overlapping dual-power supply product has an installation mode that an opening spring is fixed on a plastic fixing piece, the fixing piece is inserted on a bottom plate, and a corresponding moving contact support is provided with a spring other end limiting groove. The installation mode spring mounting falls off the damage from the bottom plate easily, leads to the separating brake function inefficacy of N looks, and the electric clearance between spring and contact is very little simultaneously, and electrical apparatus insulating properties is not enough.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a moving contact opening spring mounting structure aiming at the technical defects that the mounting structure of the N-phase contact spring of the existing dual-power-supply product with overlapped neutral lines is complex, the spring fixing piece is easy to fall off and damage and the electric clearance of the spring is small, the opening spring force is converted into the opening force to the maximum extent, and the most efficient utilization of the spring force is realized; meanwhile, the opening spring is directly arranged on the contact support, so that the installation is firm and reliable, the falling is not easy to occur, other parts are not needed, and the installation is convenient and reliable; the contact supports and the bottom plate are provided with the opposite limiting grooves, so that the bending deformation of the spring during compression is reduced, the spring moves more reliably, and the electric gap between the spring and the contact copper sheet is ensured.
Technical scheme
In order to realize the technical purpose, the utility model provides a pair of moving contact separating brake spring mounting structure, including the contact support, separating brake spring and bottom plate, its characterized in that: spring mounting bosses are arranged on two sides of the contact support, spring movable limiting grooves are formed in the positions, corresponding to the spring mounting bosses, of the bottom plate, one end of a tripping spring is sleeved and fixed on the spring mounting bosses of the contact support, and the other end of the tripping spring is arranged in the spring movable limiting grooves in the bottom plate.
Further, the spring mounting boss is located the spring groove of stepping down on the contact support, separating brake spring one end suit is located on the spring mounting boss that the contact supports the spring inslot of stepping down, and the other end is arranged in spring activity spacing groove and spring on the bottom plate step down the space of groove formation in.
Furthermore, spring mounting bosses are symmetrically arranged on two sides of the contact support, and at least two brake separating springs are respectively mounted on the spring mounting bosses to provide brake separating force for the moving contact.
Preferably, the spring mounting boss is provided with a deformation groove, and the outer circular surface is a conical surface.
Advantageous effects
The utility model provides a moving contact opening spring mounting structure, the opening spring force is converted into opening force to the maximum extent, the most efficient utilization of the spring force is realized; meanwhile, the opening spring is directly arranged on the contact support, so that the installation is firm and reliable, the falling is not easy to occur, other parts are not needed, and the installation is convenient and reliable; the contact supports and the bottom plate are provided with the opposite limiting grooves, so that the bending deformation of the spring during compression is reduced, the spring moves more reliably, and the electric gap between the spring and the contact copper sheet is ensured.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Examples
As shown in fig. 3 and 4, a moving contact opening spring mounting structure includes a contact support 1, opening springs 2 and a bottom plate 3, wherein spring mounting bosses 101 are disposed on two sides of the contact support 1, in this embodiment, the spring mounting bosses 101 are symmetrically disposed on two sides of the contact support 1, and at least two opening springs 2 are respectively mounted on the spring mounting bosses 101 to provide opening force for a moving contact.
As shown in fig. 4, a spring movement limiting groove 301 is provided on the bottom plate 3 corresponding to the spring mounting boss 101, one end of the opening spring 2 is fixed on the spring mounting boss 101 of the contact support 1 in a sleeved manner, and the other end is disposed in the spring movement limiting groove 301 on the bottom plate 3. Specifically speaking, as shown in fig. 1 and 2, the spring installation boss 101 is located in the spring relief groove 102 on the contact support 1, one end of the opening spring 2 is sleeved on the spring installation boss 101 of the contact support 1 and located in the spring relief groove 102, and the other end is arranged in a space formed by the spring movement limiting groove 301 and the spring relief groove 102 on the bottom plate 3. The spring mounting boss 101 is provided with a deformation groove 101a, and the outer circular surface 101b is a conical surface.
The embodiment of the utility model provides a pair of moving contact separating brake spring mounting structure installs the direct interference fit of separating brake spring on two bosss that the contact supported, and the installation is firm, is difficult to drop in the moving contact motion process.
