Description
Technical field
The invention belongs to illuminate articles for use technical field, relate to a kind of LED handheld formula shatter-resistant electricity
Cylinder.
Background technology
Handheld flashlight i.e. pocket lamp, for the portable electrical equipment of illumination.Modern torch one
As be divided into electric filament lamp, LED, HID etc..English: flashlight or torch, be
A kind of hand-held electronic illuminations.One typical pocket lamp has one to supply via battery
The bulb of electricity and focusing mirror, and have for hand-held handle type shell.Although phase
When simple design, it is just invented, because it must be tied to the late 19th century always late
Close the invention of battery and bulb.In early days because the electric power storage power of battery is not enough, therefore exist
In English, it is referred to as " flashlight ", implies that of short duration lamp.
General pocket lamp includes lamp cylinder and tail-hood, is provided with battery in lamp cylinder, and its front end is provided with
LED light source and the PCB being provided with Positive contact terminal, be provided with negative pole inside tail-hood
Contact terminal.Generally the both positive and negative polarity of battery respectively with the positive contact end of PCB
Son, the negative contact terminal of tail-hood compress electrical connection.Pocket lamp is the most necessary
By multiple test link, in whereabouts test wherein, due to the gravity of battery self
Relatively big, in dropping process, the both positive and negative polarity contact terminal of electrical connection pressed against is caused relatively
Big impulsive force, is easily caused PCB and is severed and hit deformation with tail-hood.
Chinese patent literature discloses the [application of a kind of pocket lamp with battery buffer assembly
Number: 201120340013.5], including lamp cylinder and tail-hood, it is provided with in the front end of described lamp cylinder
Light source assembly, is provided with battery therein, and described light source assembly includes LED light source and sets
There is the PCB of Positive contact terminal, inside described tail-hood, be provided with cathode contact end
Son, between the positive pole of described battery with described Positive contact terminal, elastic compression electrically connects,
It is provided with in described lamp cylinder and limits the locating part that described battery moves, described negative contact terminal
And elastic compression electrically connects between the negative pole of described battery, and at described tail-hood with described
It is provided with bolster between the negative pole of battery.
Such scheme limits battery by locating part and axially and moves radially, and by buffering
Part absorb can not axial impact force, prevent PCB and Positive contact terminal from being severed,
Really preferable protective effect is played.But, in this scenario, Positive contact terminal makes
It is fixing terminal, the positive pole of battery and positive contact with elastic thimble or Positive contact terminal
Set elastic component between terminal, realized positive pole and the Positive contact terminal of battery by elastic component
Elastic compression electrical connection, elastic component can be the helical spring of metal, it is also possible to be to lead
The elastic polymer material of electricity.When Positive contact terminal is elastic thimble, elastic thimble
Production cost higher, and fixing with PCB be connected inconvenience, and work as positive contact
When terminal is the structure that fixing terminal adds elastic component, fixing terminal on the one hand will be with PCB electricity
Road achieves a fixed connection, and on the other hand also to achieve a fixed connection with elastic component, otherwise bullet
Property part likely departs from locating part and causes Positive contact terminal just cannot contact battery
Pole, therefore such scheme has on the production cost, attachment structure of Positive contact terminal
Require further improvement part, thus improve protecting against shock effect further.
