The PCB lamp panel has simple structure, convenient manufacturing, and easy assembling and disassembling, is connected as a whole by the clamping connection mode of the metal clamping pieces without relative movement, and does not generate winding and clamping among the PCB lamp panels in assembling, thus being more convenient for assembling.

Description

The PCB lamp plate

Technical field

The utility model relates to light fixture, refers in particular to PCB printed circuit lamp plate.

Background technology

At present, the both positive and negative polarity exit at current its two ends of PCB lamp plate is and is welded with metal and draws port on market, insert the both positive and negative polarity metal of two PCB lamp plates by terminal respectively and draw port, two PCB lamp plates are electrically connected with the two ends connection that is connected lead.This PCB lamp plate has been realized the blocking making, but also there is following shortcoming in it: metal port need be welded on the positive and negative end of PCB lamp plate, because pad is very little, its welding difficulty is big, and need to weld four metals respectively at the two ends of a PCB lamp plate and draw port, workload is big; When two PCB lamp plates are linked together, also need to have the terminal that connects lead and insert the metal port connection by two, the production parts that need are more relatively, the production cost height, and difficulty of processing is big, and owing to be to connect two PCB lamp plate freely-movables mutually by lead, cause tangling between the lamp plate, make troubles to installation.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of PCB lamp plate, and it has avoided use splicing ear and metal port, and is simple in structure, and manufacturing and connection thereof are all very convenient, and with low cost.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is a kind of PCB lamp plate, it mainly comprises the PCB substrate, the lamp that on described PCB substrate, is electrically connected, be respectively arranged with the sheet metal of drawing of both positive and negative polarity at the two ends of described PCB substrate top and bottom, it is characterized in that the both positive and negative polarity of an end draws to conduct respectively on the sheet metal therein to be fixedly connected with the metal intermediate plate.

Wherein, described metal intermediate plate is clip shape, draws sheet metal at the both positive and negative polarity that is connected with described metal intermediate plate and offers through hole with respect to described end one side, and described metal intermediate plate passes described through hole and draws sheet metal with described both positive and negative polarity respectively and conduct and fixedly connected.

Wherein, the end regions of drawing between the sheet metal at the described both positive and negative polarity that is provided with described metal intermediate plate offers an opening, described opening is communicated with described through hole, and described metal intermediate plate wears respectively to described both positive and negative polarity by described opening and draws the sheet metal place, and conducts fixedly connected with it.

Stretching out in the other end end corresponding to described opening of described PCB substrate forms a projection, and when two described PCB substrate in combination together the time, described projection just in time embeds in the described opening.

By rectifying negative electricity conducting fixing metal intermediate plate at one of PCB lamp plate, only be provided with at the other end and draw sheet metal, when two PCB lamp plates connect, the both positive and negative polarity of one end is drawn sheet metal and is sticked into respectively in the fixing both positive and negative polarity metal intermediate plate of another piece PCB lamp plate one end, realizes that two PCB lamp plates are electrically connected; When needs split, directly throw off at once.The metal intermediate plate is made as clip shape, it can well clamp connected both positive and negative polarity and draw sheet metal, two PCB lamp plates are connected as one, increased the reliability that is electrically connected, also strengthened the being connected and fixed property of two PCB lamp plates, make its not freely-movable relatively, make things convenient for each lamp plate to connect the back and install.

The specific embodiment

At the utility model, now lift a preferred embodiment and describe as follows: referring to Fig. 1 in conjunction with diagram:

The PCB lamp plate, it mainly comprises PCB substrate 1, according to prior design and printing connecting circuit is arranged on substrate, according to design in advance, several lamps 2 are installed on this substrate 1, this lamp can be common bulb, also can be LED lamp or other lamps, the LED lamp of preferred energy-conserving and environment-protective;

On the upper and lower surfaces of the end of an end of PCB substrate 1, keep at a certain distance away and be provided with both positive and negative polarity respectively and draw sheet metal 3, this is drawn sheet metal 3 and has certain area of plane, and the end of drawing between the sheet metal 3 from this both positive and negative polarity is outward extended with a projection 31;

Be respectively arranged with both positive and negative polarity at the other end of PCB substrate 1 and draw sheet metal, draw sheet metal at both positive and negative polarity and offer a through hole 5 with respect to its end, place one side, offer an opening 51 between this through hole 5 and this end, this opening 51 is drawn between the sheet metal at both positive and negative polarity, the profile coupling of the shape of this opening 51 and projection 31; Two metal intermediate plates 6, referring to Fig. 2, it is clip shape, by this opening, its folder shape hollow part is sheathed with both positive and negative polarity respectively and draws the sheet metal place, make this metal intermediate plate 6 and draw sheet metal and conduct and be connected and fixed by welding, after fixing, this end certain distance is stretched out at these metal intermediate plate 6 its two clamping positions, this distance satisfies when two PCB substrate assemblings, when the both positive and negative polarity on these metal intermediate plate 6 another piece of clamping PCB substrates was drawn sheet metal 3, referring to Fig. 3, it is positioned at just drew sheet metal 3 positions and electrical connection with it.Certainly, above-mentioned through hole 5 can not wanted yet, and directly draws two sheet metals that stretch out this end of welding on the sheet metal at both positive and negative polarity, and makes it combination forming for pressing from both sides the shape attitude; Also can draw sheet metal one side and offer two through holes 5 respectively at both positive and negative polarity, this through hole 5 does not have opening 51, do not form projection 31 at the other end accordingly yet, metal intermediate plate one end is passed again its electrical connection is fixed on behind this through hole and draw the sheet metal place, its shortcoming is when passing this through hole, it is bigger to open force rate, may influence the clamping force of metal intermediate plate 6.

When two PCB substrate in combination, the both positive and negative polarity that the both positive and negative polarity metal intermediate plate 6 of an end clamps the other end is drawn sheet metal 3 and is realized being electrically connected, and projection 31 also embeds two PCB substrates better are combined into together simultaneously, and relative motion does not take place.

PCB lamp plate of the present utility model, it has omitted metal port and has connected conductor terminal, simple in structure, easily manufactured, be easy to assembling and split, and can clamp connected mode by the metal intermediate plate, each PCB lamp plate is connected as one, relative motion can not take place, can not produce the folder that twines between each PCB lamp plate when assembling, more convenient assembling.
