Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of SMD sensitive switch, can be connected fast, enhances productivity with wiring board, strengthens properties of product, extends consumer to the service time of product.
SMD sensitive switch of the present utility model, comprises pedestal and metal terminal, and described metal terminal is 90 ° of bendings, comprise by vertical section from pedestal to downward-extension with to be positioned at bottom vertical section and along the horizontal segment be affixed on wiring board of pedestal horizontal expansion.
Further, described metal terminal comprises first, second and third metal terminal successively, the vertical section of first, second and third metal terminal described is all positioned on the longitudinal center face of pedestal, and the bending direction and first of described second metal terminal, the bending direction of the 3rd metal terminal are contrary.
Further, the length of the horizontal segment of described metal terminal is the 40%-50% of pedestal lateral length.
Further, described pedestal comprises base and upper cover, and described upper cover bottom cover is combined on base, and the face that covers of described upper cover and base is provided with sealing ring.
The beneficial effects of the utility model: SMD sensitive switch of the present utility model, comprise pedestal and metal terminal, described metal terminal is 90 ° of bendings, comprise by vertical section from pedestal to downward-extension with to be positioned at bottom vertical section and along the horizontal segment be affixed on wiring board of pedestal horizontal expansion.Sensitive switch of the present utility model, brand-new SMD structure is adopted to be connected with wiring board, namely fit bonding by the horizontal segment of metal terminal with wiring board, compare existing plug-in type sensitive switch, locate between sensitive switch of the present utility model and wiring board fast, production efficiency is high, without the need to manual operation, be applicable to production of machinery operation, bonding strength is higher, enhance properties of product, extend consumer to the service time of product.Meanwhile, covered by sealing property because pedestal adopts between base and upper cover, enhance anti-scaling powder, the dirt exclusion capabilities of pedestal.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A cutaway view in Fig. 1;
Fig. 3 is B-B cutaway view in Fig. 1.
Embodiment
It should be noted that, " longitudinal direction " in the utility model refers to the length direction of pedestal, and " transverse direction " refers to the Width of pedestal.As shown in the figure: the SMD sensitive switch of the present embodiment, comprise pedestal 1 and metal terminal 2, wherein pedestal 1 is the shell structure of cuboid-type, inside has the common components such as switching mechanism, leaf spring, metal terminal 2 stretches out in pedestal 1, and in 90 ° of bendings, metal terminal 2 comprise by vertical section 21 from pedestal 1 to downward-extension with to be positioned at bottom vertical section and along the horizontal segment 22 be affixed on wiring board of pedestal horizontal expansion.Fit bonding by the horizontal segment 22 of metal end 2 with wiring board, compare existing plug-in type sensitive switch, locate between sensitive switch of the present utility model and wiring board fast, production efficiency is high, without the need to manual operation, be applicable to machine continuous productive process.
The quantity of metal terminal is according to electrical demands, and quantity is generally 2 or three.In the present embodiment, technology number of terminals is 3, is followed successively by first, second and third metal terminal 2a, 2b, 2c, and the component that first, second and third metal terminal 2a, 2b, 2c are different from pedestal respectively connects, and has different functions respectively.The vertical section 21 of first, second and third metal terminal 2a, 2b, 2c is all positioned on the longitudinal center face of pedestal 1, the bending direction and first of described second metal terminal 2b, the bending direction of the 3rd metal terminal 2a, 2c are contrary, the horizontal segment 22 of the sub-2a of the first metal end and the 3rd metal terminal 2c that are that is positioned at two ends is positioned at homonymy, as shown in Figure 2, the horizontal segment of first and third metal terminal is all positioned at the right side of vertical section.The horizontal segment 22 of the second metal terminal 2b is positioned at the heteropleural of the horizontal segment 22 of first and third metal terminal, and as shown in Figure 3, the horizontal segment of the second metal terminal is all positioned at the left side of vertical section.The beneficial effect of such setting to make sensitive switch all have support in the both sides in longitudinal center face, and sensitive switch resistance to overturning is good.
As the further improvement of technique scheme, the length of the horizontal segment 22 of described metal terminal 2 is the 40%-50% of pedestal 1 lateral length, that is horizontal segment 22 is positioned at base width scope, the free end of horizontal segment is near pedestal transverse side, and such setting both can ensure the support superstructure that the length of horizontal segment 22 can be stable.
As the further improvement of technique scheme, described pedestal 1 comprises base 11 and upper cover 12, and described upper cover 12 bottom cover is closed on the pedestal 11, and described upper cover 11 is provided with sealing ring 3 with the face that covers of base 12.Because pedestal to adopt between base and upper cover by encapsulation process, enhance support and upper cover prevents scaling powder, dirt exclusion capabilities.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model but not profile and size restrictions, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
