AI Technical Summary
The existing R7S lamp holder is costly and reduces lamp performance in applications with protection ratings of IP65 and above. Traditional methods of adding lamp housings also lead to increased maintenance costs.
The new waterproof lamp holder structure includes a bracket screw, spring bracket, first sealing ring, connecting base, spring, wire, contact head, conductive contact, outer sleeve, second sealing ring, and fastening hexagonal nut. The sealing ring is fastened to the metal outer sleeve to achieve waterproof sealing. The contact head makes reliable contact with the ceramic lamp head. The insulation level is improved by combining insulated wire and ceramic material.
The protection level of the R7S lamp holder and luminaire has been increased to IP65, while the ease of installation and shock resistance of the luminaire have been improved, and the maintenance cost has been reduced.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of lamp holder structure, and more specifically to a novel R7S waterproof lamp holder structure device. Background Technology
[0002] Existing R7S lamp holders only provide support and conductivity for the luminaire. Especially in some special applications, R7S lamp holders can also be shock resistant and achieve a protection level of Ip65 or higher. Traditional lamp holders cannot be used, or they achieve this by adding a protective shell to the luminaire, which is costly and greatly reduces the performance of the luminaire and increases the maintenance cost. Therefore, the current market urgently needs an R7S lamp holder with a protection level of Ip65 or higher. Summary of the Invention
[0003] The main technical problem solved by this utility model patent is to provide a new type of waterproof lamp holder, which enables the lamps with R7S lamp holders to be powered on and operated through the new R7S waterproof lamp holder, and also protects the electrical appliances to achieve the national standard insulation level and the protection level of IP65 during operation.
[0004] To solve the above-mentioned technical problems, this utility model, R7S lamp holder structure, more specifically, is a new type of waterproof lamp holder, including bracket screws, spring clip brackets, a first sealing ring, a connecting base, a spring, wires, contact heads, conductive contacts, outer sleeves, a second sealing ring, and a fastening hexagonal nut.
[0005] The new type of lamp holder connects electrically with the ceramic lamp head via a contact point, while simultaneously securing the ceramic lamp head with a hexagonal screw via a second sealing ring and a metal outer sleeve. The second sealing ring and the ceramic lamp head are pressed together during tightening to achieve a tight seal and waterproof effect. Furthermore, the contact point and double-insulated high-temperature resistant wire ensure that the overall insulation level of the new waterproof lamp holder meets national standards. The reliable contact between the contact point and the ceramic lamp head is achieved through the cooperation of the bracket screw, spring bracket, first sealing ring, connecting base, spring, outer sleeve, and nut, thus realizing the overall waterproof R7S lamp holder design.
[0006] As a further optimization of this technical solution, this utility model uses sealing silicone to seal the wires and the R7S lamp holder, so that the internal live parts are in a sealed space. At the same time, the insulating ceramic gives the lamp holder a high pressure resistance to further ensure safety. In addition, the internal spring and external spring clip bracket also make it more convenient and stable to install the R7S lamp holder.
[0007] The beneficial effects of this utility model R7S waterproof lamp holder are: it facilitates the installation of R7S lamp holders and lamps, while improving the protection level of such lamps to IP65. The spring provides a preload force to the contact head from the connecting base to the outer sleeve, increasing the lamp's shock resistance.
[0008] This utility model of R7S waterproof lamp holder allows R7S lamp holders and tubes to be connected to the circuit through this patented structure, achieving an IP65 protection level and enabling quick installation. Attached Figure Description
[0009] The present invention will now be described in further detail with reference to the accompanying drawings and specific implementation methods.
[0010] Figure 1 This is an explosion diagram of a novel waterproof lamp holder according to the present invention.
[0011] Figure 2 This is a half-sectional schematic diagram of a novel waterproof lamp holder according to the present invention.
[0012] In the diagram: 1. Bracket screw; 2. Spring bracket; 3. First sealing ring; 4. Connecting base; 5. Spring; 6. Wire; 7. Contact head; 8. Conductive contact; 9. Outer sleeve; 10. Second sealing ring; 11. Nut; 12. Lamp tube ceramic head; 13. Glass tube. Detailed Implementation Example
[0013] The following is combined with Figure 1 and Figure 2 This embodiment describes a novel R7S waterproof lamp holder structure, specifically a new type of R7S waterproof lamp holder, comprising a bracket screw 1, a spring clip bracket 2, a first sealing ring 3, a connecting base 4, a spring 5, and double conductors 6 (layer-insulated high-temperature resistant conductors); contact heads 7, conductive contacts 8, and outer sleeves 9 are made of metal. A second sealing ring 10 and a nut 11 are hexagonal nuts for fastening; the lamp tube ceramic head 12 is sealed to the contact head 7; the second sealing ring 10 and the outer sleeve 9, along with the nut 11, fix the lamp tube ceramic head 12; the second sealing ring 10 is located between the lamp tube ceramic head 12 and the outer sleeve 9.
[0014] The spring 5 and the contact head 7 are located between the connecting base 4 and the outer sleeve 9; and the spring 5 provides the contact head 7 with a preload force from the connecting base 4 to the outer sleeve 9; the connecting base 4 and the outer sleeve 9 are connected.
[0015] The first sealing ring 3 is located between the spring clip bracket 2 and the connecting base 4, and the first sealing ring 3 has a conical structure. Figure 2The spring clip bracket 2 and the connecting base 4 are fixedly connected by bracket screws 1; the wire 6 passes through the middle part of the first sealing ring 3. The first sealing ring 3 and the second sealing ring 10 are made of silicone.
[0016] The second sealing ring 10 and the lamp ceramic head 12 are cylindrical; the second sealing ring 10 has a through hole in the middle, and the diameter of the through hole is smaller than the diameter of the lamp ceramic head 12. This facilitates a tight contact between the second sealing ring 10 and the lamp ceramic head 12, thus achieving a sealing effect.
