Description
Technical field
The utility model relates to a kind of contactor, belongs to low-pressure electronic equipment product technical field.
Background technology
Contactor is that one utilizes coil to flow through current induced magnetic field, makes contact closure to reach the electrical equipment of control load, and its major control is to liking motor and other circuit loads.In some lv contactor, what its terminal screw mainly adopted is a watt grommet screw, as shown in Figure 6, contactor product is in long-distance transport process, very easily occur that screw rocks seriously, even from watt phenomenon that pad comes off, bring many unnecessary troubles to the user of contactor.Therefore, for the little cage contactor adopting watt grommet screw, easily rocking, easily coming off of its terminal screw is a problem needing solution badly.Common solution is adopt the mode of reinforcement to be fixed, or is provided with screw thread in screwed hole in head of screw and the cap that is mated, makes it match.
Summary of the invention
The purpose of this utility model overcomes that prior art medium and small cage contactor terminal screw easily rocks, caducous deficiency, a kind of screw anti-shake anticreep contactor is provided, watt grommet screw is combined with panel, housing, makes watt pad and screw eliminate the phenomenon of rocking, coming off.
To achieve these goals, the technical solution of the utility model is:
A kind of screw anti-shake anticreep contactor, comprising: panel, watt grommet screw, static contact component, housing.Static contact component is arranged in the draw-in groove of housing, and static contact component is fixed by housing; Erecting of panel is at housing tip, and be fixed in housing by the connected mode of buckle by panel, a watt grommet screw is arranged in the screwed hole of static contact component; Panel is provided with screw mounting hole, around the one side towards housing, screw mounting hole of this panel, is provided with positioning element, this positioning element extends in housing and end has the bending of certain angle.
Further, the positioning element of above-mentioned panel is specifically arranged on the bore edges of screw mounting hole, and is a pair thin slice symmetrical centered by this screw mounting hole.
Further, two thin slices of positioning element bend to the direction away from the other side at a certain angle, and the thickness of thin slice is preferably 0.5mm, and have the feature of flexible location; When screw upwards screws out certain position, can contact with positioning element, now screw continues to move upward, and positioning element extends to both sides, and after screw screws out completely, positioning element applies certain pressure, to ensure the stability of screw can to a screw watt pad.
Further, the sidewall locations of housing is also provided with limiting component, the limiting component on every two adjacent walls of housing is symmetrical, and limiting component is interference fit with watt pad.When screw upwards screws out certain position, can contact with limiting component, now screw continues to move upward, limiting component extends to the direction being away from the other side, after screw screws out completely, limiting component applies certain pressure, to ensure the stability of screw can to watt grommet screw.
Further, static contact component comprises subsidiary loop static contact component and major loop static contact component, and watt grommet screw of major loop is spacing by two sidewalls of housing, and watt grommet screw of subsidiary loop is spacing by panel.When watt grommet screw exits from the screwed hole of subsidiary loop fixed contact, contact with the positioning element of panel after a watt pad arrives certain position, continue upwards to run, watt pad can be subject to panel externally applied forces, when screw no longer moves, due to the effect of external force, panel can well by fixing for watt pad; When watt grommet screw exits from the screwed hole of major loop fixed contact, contact with housing limiting component after a watt pad arrives certain position, continue upwards to run, watt pad can be subject to housing externally applied forces, when screw no longer moves, due to the effect of external force, housing can well by fixing for watt pad.
By adopting technique scheme, make to be arranged on watt grommet screw on described major loop static contact component when coming off, locate by the limiting component above adjacent two sidewalls of housing, when watt grommet screw be arranged on described subsidiary loop static contact component comes off, locate by the positioning element of panel, watt grommet screw can be fixed, efficiently solve contactor in long-distance transport, the problem that its watt of grommet screw rocks, comes off.Improvement project structure of the present utility model is simple, is easy to realize, with low cost.After adding positioning element of the present utility model and limiting component, make contactor in assembling and transportation, not only reduce watt grommet screw and rock the noise caused, and greatly reduce the risk that in transportation, watt grommet screw is lost.
