Detailed Description
The utility model will be further described with reference to the accompanying drawings in which: as shown in the figure, a normally closed contact installation snak link's of contactor structure, includes base 1 and contact carrier 2, be equipped with first contact 21 and elastic mounting subassembly 22 on the contact carrier, the elastic mounting subassembly includes buckle 4, be equipped with platform 11 on the base, be equipped with the spread groove 12 that sets up with the buckle relatively on the platform, the buckle is including detaining body 41, be equipped with couple 42 on the knot body, detain body circumference outer wall with spread groove inner wall clearance fit, the couple support press in on the platform. Contact holder's gravity passes through the couple and acts on the platform, and on the other hand, this resilient mounting subassembly can include elastic component (preferably spring), and this spring one end can directly or indirectly support and press on first contact, and the other end can support and press on detaining the body, and it indicates to detain the body and spread groove clearance fit to say so has the clearance between the circumference of the body and the circumference inner wall of spread groove, is interference fit not between the two like this, the installation of being convenient for, can prevent that the installation is not in place and the installation jamming leads to the problem of efficiency reduction to take place.
In the present invention, as shown in the figure, an avoiding groove 121 is formed on the inner wall of the connecting groove opposite to the buckle body. Through the avoidance groove, the thickness of the installation position can be reduced, clearance fit is realized more easily, and the installation is convenient.
In the present invention, as shown in the figure, the buckle body includes a side wall 401 and a bottom wall 402, and further includes a reinforcing rib 403, wherein the reinforcing rib is partially disposed on the bottom wall and partially disposed on the side wall. During the experiment of the mechanical life of a product, the buckle body in the prior art easily causes the breakage of the spring buckle, the spring buckle is not in place, the contact spring force is reduced or even disappears, the contact fusion welding and the failure of the whole contactor are caused, reinforcing ribs are added on two sides of the buckle, the stress can be offset, the impact strength of the buckle is enhanced, and the breakage caused by the impact force of the magnet attraction is prevented.
