In order to meet the requirements, a lampshade and an outlet of an L ED working lamp are usually sealed in a glue sealing mode, an aluminum alloy shell and an aluminum substrate circuit board are usually adopted to ensure good heat dissipation, and an outlet cable and the circuit board are usually connected in a welding mode, so that the following defects are caused:

1. the sealant adopted in the sealant form needs a certain time for curing, and less sealant needs half an hour, and more sealant needs several hours, so that the production efficiency is not improved;

2. the sealant has requirements on the ambient temperature and humidity in the curing process and is easily interfered by external environmental factors to influence the curing effect, so that the sealing and waterproof performance of the L ED working lamp is influenced;

3. the glue sealing form is not beneficial to secondary disassembly and assembly during repair, so that the after-sale maintenance cost is increased;

moreover, the outgoing cable and the circuit board are connected in a welding mode, manual welding is usually needed, different models need to be made for connecting cables with different wire lengths, different materials and different connecting modes, and large-scale production is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, overcome the defect that prior art exists, provide a production efficiency height, low in production cost, repair with low costs, the product commonality is high, and more is favorable to the plug-in components formula L ED work light of scale production.

The utility model provides a plug-in components formula L ED working lamp, including casing, lamp shade, lamp plate circuit board, plug-in components seat, the lamp plate circuit board is located between casing and the lamp shade to fix in one side of casing, the opposite side at the casing is fixed to the plug-in components seat, be equipped with the contact pin soldering lug on the lamp plate circuit board, the contact pin terminal on the plug-in components seat runs through the casing passes through the contact pin soldering lug is fixed on the lamp plate circuit board, be equipped with the concave circle that is used for placing the lamp shade sealing washer on the casing, the lamp shade sealing washer is located between lamp shade and the casing.

Further, the lamp shade is tightly pressed on the shell through a lamp shade pressing plate, and the lamp shade pressing plate is fixed on the shell through screws.

Further, all be equipped with the locating hole on lamp shade clamp plate and the lamp plate circuit board to guarantee to carry out the correct positioning in production assembling process.

Further, the lamp shade is the integral lens lamp shade, and the lens on the integral lens lamp shade and the lamp shade are integrally formed by injection molding, so that the process of installing the lens on the lamp shade is reduced.

Furthermore, be equipped with the confession on the lamp plate circuit board the trompil that the contact pin terminal passed, contact pin terminal accessible in the plug-in connector seat passes from the lamp plate circuit board back through this trompil, welds with contact pin soldering lug again.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model can remove the procedure of manual welding wire outlet cable in the whole assembly process, and realize full automatic production;

2. the utility model can realize the protection grade above IP67 without using glue sealing or pouring process, can obviously shorten the production period, and can easily carry out secondary disassembly and assembly;

3. the utility model can meet the wire outlet requirements of various wire lengths and plug connectors only by adapting to the corresponding wire harnesses and plug connectors, and does not need to make different models for different wire outlet forms for production;

4. the utility model discloses can improve production efficiency, reduction in production cost reduces the cost of reprocessing, improves the product commonality, and more is favorable to the scale production, more is suitable for popularization and application.
