Abstract
The utility model relates to a plastic safety lamp holder, which is especially suitable to be matched and installed on a self-ballasted lamp and an electric incandescent lamp. The utility model is composed to an integrality by the connection of a conductivity cap and a lamp cap body, while the lamp cap body made into an entirety by plastic is fixedly connected with an electrode. The electrode is cylindrical, and two corresponding points also respectively divide out a piece of elasticity conductive strip. The conductivity cap and the electrode are all connected with an annular recess on the lamp cap body, and the conductive strip is matched with a recess slot on the lamp cap body. Because the lamp cap adopts plastic in place of existing metallic material, the lamp cap can be injected to a mold at a time to achieve the purpose of easy producing and low cost. The utility model reaching IEC quality requirements has the advantages of safety, reliability and thorough elimination of unsafe hidden danger.
Description
The utility model relates to a kind of lamp holder, particularly a kind ofly is installed in plastic safety lamp holder matching used with it on ballast lamp.
By the IEC requirement, when ballast lamp used, the metalwork of lamp holder part should not expose.But because of the manufacturing process problem, existing use from ballast lamp, have a lot of lamp holders often not reach requirement, therefore just exist a lot of unsafe hidden danger.
The purpose of this utility model is to provide a kind of IEC of meeting requirement, low cost of manufacture, plastic safety lamp holder safe in utilization, reliable.
The utility model is achieved in that the plastic safety lamp holder connects into whole the composition by conductive cap and body, and body is the integral body that is made of plastics, and also is fixedly connected with conductive electrode on the body.
Fig. 1. structural representation of the present utility model.
Fig. 2. the vertical view of Fig. 1.
Fig. 3. the A-A view of Fig. 2.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Conductive cap (1) is the cylindrical shape of band through hole (5) in the middle of being made into by metal material.
Conductive electrode (2) upper end is conical, the lower end is a cylindrical shape, respectively have a slice to split and have the conducting strip (4) of the bending shape that an end is connected with conductive electrode (2) from conductive electrode (2) in two corresponding positions of cylindrical shape part, conical place, upper end and conducting strip (4) are 90 ° and have located a through hole (7).
Body (3) is by plastic injection-moulded one-tenth, and for there is the integral body of cavity the centre, upper and lower end is a cylindrical shape, and the centre is a conical transition, and global shape is similar substantially to the metal-back profile of prior art.Have on the inwall of upper end the cannelure (6) that cooperates with conductive cap (1) is arranged in reinforcement and the wall, the lower end peripheral outer wall is a thread-shaped, the groove that two corresponding positions, thread-shaped upper end respectively have a strip to cooperate with conducting strip (4), being with groove has a tubular line hole (9) in 90 ° of sidewalls of locating, the cannelure (8) that cooperates with conductive electrode (2) is arranged in the thread-shaped wall.
The lower end cylinder of conductive electrode (2) is partly inserted in the cannelure (8) on the body (3), the conical portion cover of upper end is engaged on body (3) the middle circle tapering part, and two conducting strips (4) embed respectively in the groove on body (3), the interior connection of cannelure (6) of at last conductive cap (1) being inserted body (3) upper end is in aggregates, and the plastic safety lamp holder is assembled into.
During use, the terminal pad of lamp holder and shell and band fluorescent tube is linked into an integrated entity, two lead-out wires are weldingly fixed on respectively in the through hole (5) of conductive cap (1) and the through hole (7) on the conductive electrode (2) and just can have used.
The utility model is compared with prior art: replace original metal because lamp holder adopts whole plastic construction Material, so lamp holder can make in an injection moulding, easy to make, cost is low, use is safe, reliably can reach again To the IEC quality requirement, thoroughly eradicated hidden danger.
