Abstract
The utility model discloses a Face contact fluorescent tube base which can be used for making elastic reeds to contact with a contact face between fluorescent tube feet, and the utility model can be used for making installation and connection stable. The utility model comprises a casing, a face cover plate, and elastic reeds 3 and 3'. The utility model is characterized in that the face cover plate is provided with a circular recess, elastic reeds 3 and 3' which are clamped at both sides of a middle cylinder, one end of the elastic reed 3 and one end of the elastic reed 3' are fixed on a supporting board behind the face cover plate, and a straight recess is penetrated through the middle cylinder through an outer margin of the casing. The utility model has the advantages of low cost, simple assembly process, high safety, and good electrical property.
Description
The face contact type daylight base is the improvement to widely used top spring point contact daylight base now.
As everyone knows, the current daylight base that generally uses is a top spring point contact, its contact-making surface is little, two contacts of each daylight base and fluorescent tube pin electrically contact the pressure that depends on the base medi-spring, will occur loose contact like this and use inconvenient, unsafe shortcoming.
China Patent No. 94207399.1 disclosed ＂ press-contacting type daylight base ＂ for overcoming the shortcoming of above-mentioned daylight base, provide a kind of face contact type, and overcome above-mentioned shortcoming, but the shortcoming of its existence is: left and right sides base can not be replaced, production mould cost height; Smoothly convenient and good to the contact of two pins when inserting base for level, elastic spring is made the shape that upwards arches upward more, and pin can only contact one side with elastic spring; When insertion or taking-up fluorescent tube, pin might cause elastic spring bending in opposite directions to damage; In addition, can only upwards install by notch when installing on the wall, if vertical the installation when making the notch level on ceiling or on the wall all has certain hidden danger to exist.
The purpose of this utility model is to provide a kind of face contact type daylight base, and it can make contacting between elastic spring and the fluorescent lamp holder is the face contact, and install connect firm.
The utility model is achieved in that it is made up of shell, surface cover, elastic contact blade, after shell is contained in surface cover, it is characterized in that a circular trough is arranged on the surface cover, groove is built-in with on the support plate after elastic spring 3,3 ' one ends that are sandwiched in the mediate cylindrical both sides are fixed on surface cover; Straight trough passes mediate cylindrical from housing outer rim edge, and when the straight trough insertion of two pins of fluorescent lamp along base, a pin passes mediate cylindrical, enters circular trough, and another pin is then at the circular trough another side, with the fluorescent lamp half-twist; Elastic spring is stuck in the mediate cylindrical both sides with two pins of fluorescent lamp, elastic spring and fluorescent lamp holder excellent electric contact, and installation connects very firm.
The utility model is established straight trough guiding fluorescent lamp holder and is inserted on cover, easy for installation, does not need the spring that uses in the prior art, reduces cost, and simplifies assembly technology again; After fluorescent tube enters circular trough, along the circular trough half-twist; Be stuck on the elastic spring of mediate cylindrical both sides, installation is connected firmly between fluorescent lamp holder and the base, can not deviate from from straight trough, and the security performance height is the face contact between them, good electrical property.
The utility model is provided by following embodiment and accompanying drawing thereof.
Figure one is the oblique view of embodiment.
Figure two is the surface cover oblique view of embodiment.
Figure three is the surface cover rearview of embodiment.
Figure four is the housing oblique view of embodiment.
With reference to Fig. 1, surface cover 2 is loaded in the housing 1, and housing 1 lower end has two osculums 10,10 ' be the power supply lead wire outlet of elastic spring 3,3 ' draw, both sides, lower end to be had base is fixed on holddown groove 4 on the fluorescent lighting fixture; One circular trough 5 is arranged on the cover 2, and the groove internal diameter is mediate cylindrical 7 diameters with two pins of fluorescent lamp in its two sideway swivel and have spacious and comfortablely slightly, and the width of circular trough 5 is not stopped to be advisable during with two pins rotations; Elastic spring 3,3 ' from circular trough 5 bottom outer rims, mould the support plate 6 of casting behind surface cover 2 and pass circular trough 5 to its other end, be sandwiched in mediate cylindrical 7 both sides, a triangle or semicircle shape are preferably rolled in the position that is sandwiched in both sides, make fluorescent tube all be in contact with it face and increase, and install also firm.Its lower end is converted into 90 °, and with Luo silk 8,8 ' be fixed on the support plate 6, straight trough 9 passes mediate cylindrical 7 from housing 1 top outer rim.When two pins of fluorescent lamp when the straight trough 9 of base inserts bases, again along circular trough 5 half-twists, with fluorescent lamp holder be stuck in securely elastic spring 3,3 ' on.Osculum 10,10 on from elastic spring 3,3 ' draw power supply lead wire from housing ' draw can be finished manufacturing operation of the present utility model.
Claims (3)
1. face contact type daylight base, comprise housing, surface cover, elastic spring 3,3 ', its characteristic is: have a circular trough on the surface cover, groove is built-in with on the support plate after elastic spring 3,3 ' one ends that are sandwiched in the mediate cylindrical both sides are fixed on surface cover, and straight trough passes mediate cylindrical by the housing outer rim.
2. face contact type daylight base according to claim 1 is characterized in that straight trough passes mediate cylindrical by cover top portion.
3. face contact type daylight base according to claim 1 is characterized in that the mediate cylindrical diameter is slightly less than the distance between fluorescent lamp two pins.
