Abstract
The utility model relates to the technical field of electric appliances, in particular to a tight-holding switch static contact of a built-in spring, which comprises a static contact sheet body, wherein the static contact sheet body is made of two reeds which are adjacent to each other and provided with openings. The tight-holding switch static contact of the built-in spring is characterized in that connecting springs are further arranged at lower parts in the middle of the two reeds. The tight-holding switch static contact of the built-in spring has the advantages of being more favorable in contact and having no bad contacting phenomenon.
Description
Technical field
The utility model relates to technical field of electric appliances, particularly a kind of tight-holding type switch fixed contact of built-in spring.
Background technology
Tight-holding type switch fixed contact be two close and have the opening reed and make, it is the position of movable touch knife contact, rely on two reeds to finish its contact to centre extruding movable touch knife, in the prior art, two reeds of fixed contact rely on the bottom of one to link together, the power of two reeds to the centre also is the connecting portion that relies on the bottom, and the static contact of this spline structure has loose contact, conduction is not very good shortcoming.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and the tight-holding type switch fixed contact that a kind of contact is better, the loose contact phenomenon can not occur---the tight-holding type switch fixed contact of built-in spring is provided.
The novel technical scheme of taking of this use is, the tight-holding type switch fixed contact of built-in spring, comprise the static contact body, the static contact body be two close and have the opening reed and make, it is characterized in that: connect spring in addition in described two reed middle lower portion.
The beneficial effects of the utility model are: the tight-holding type switch fixed contact of so built-in spring has the advantage that contact is better, the loose contact phenomenon can not occur.
Description of drawings
Fig. 1 is the structural representation of the utility model tight-holding type switch fixed contact.
Wherein: 1, reed 2, spring
Specific embodiments:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the tight-holding type switch fixed contact of built-in spring comprises the static contact body, the static contact body be two close and have opening reed 1 and make, it is characterized in that: connect spring 2 in addition in described two reed 1 middle lower portion.
Because the pulling force of spring is arranged, make reed to the centre, contact well with contact knife during use, possessed effect of the present utility model.
