Description

Application area
The invention relates to lighting engineering, and more specifically to bayonet and screw cartridges for incandescent lamps of the type DS (minion), designed for general, local and outdoor lighting in everyday life in power networks with voltage of 220V and frequency of 50 Hz. In accordance with GOST 12.2.007.13-88.

The lampholders for lamps with bayonet and screw cap have the following requirements:
1. Electrical requirements, which are to ensure reliable contact pressing and the associated conductivity at the contacts.

2. Mechanical requirements, consisting in the mechanical strength of the product, its resistance to vibration and shaking in a given range of frequencies and shock loads. Cartridges operating in conditions of increased vibration and shaking must withstand the following vibration and shock loads: the frequency range from 1 to 100 Hz with an acceleration of 1 m / s ² and single impacts with an acceleration of 3 m / s ² lasting from 40 to 60 ms.

 3. The design and technological requirements consist in the ability to produce cartridges by the simplest methods (stamping, pressing, heading, etc.), as well as the minimum laboriousness in manufacturing and ensuring high quality without the use of individual adjustments.

 4. Operational requirements, consisting in ease of installation, dismantling, visual inspection and adjustment.

 As analogues of the claimed invention, the information is given in the "Reference book on lighting engineering", p.150-156, edited by Yu. B. Aisenberg, M., Energoatomizdat, 1983, the book by E.S. Rosenthal "Electrical Installation Devices", p.5-18, M., Energoatomizdat, 1987, catalog of electrical products "JSC" Minimaks "1999

The standard technical documentation is taken as a prototype: GOST 361-78 "Bayonet cartridges for electric incandescent lamps. Technical conditions". (Canceled and replaced by GOST 9806-90 GOST 2746-90 (IEC 238-87), M., Publishing house of standards, 1991 (5)
The disadvantages of the above technical solutions are the complexity in the structural and technological design, as well as the lack of the ability to visually control the reliability of electrical contacts, because everything is hidden constructively in the cartridge.

 Known cartridge designs are intended for only one specific cap - screw type. B 15/18, B 15/17, and B 15/19 according to GOST 17100-79.

 There is no cartridge for turning on incandescent lamps with a pin base according to GOST 17100-79 (6) in the industry, which creates certain inconveniences in the manufacturing and operating techniques.

Description of the claimed invention
The claimed invention is directed to the creation of an electric cartridge for incandescent lamps in a simplified structural and technological design, installation and reliable in operation for both lamps with a pin base and lamps with a screw base as if in a single design.

 The cartridge in the proposed invention can be called unified on the basis that both with a screw base and a pin consist of two main parts: couplings with conductive elements and sleeves.

 The sleeve in this case, essentially the purpose is a cover of conductive elements of the coupling.

 Structurally and in size, the sleeve remains unchanged for both types of cartridges, both with screw and pin base.

 It is especially important to note the coupling - as a particularly important main load-bearing complex of the cartridge’s power transmission, under certain safety conditions (for example, the cartridge is installed somewhere in the device’s body, where the specialist penetrates when the power is off, otherwise there will be a shock or short circuit) can be installed without a sleeve.

 The sleeve serves as a cover for the conductive elements of the cartridge coupling and is mounted on the finished, assembled for commissioning of the coupling, from the side of the conductive wires.

 In more detail, the indicated technical solution of the electron cartridge is illustrated in FIG. 1-7.

 Figure 1 presents the inventive unified electric cartridge for electric lamps "Mignon" with a pin base, in which both the electrical contacts of the bulb are displayed on the end of the base.

 Here, the inventive cartridge with a pin connection (Fig. 1) consists of two main parts: a coupling 1 with conductive elements and a sleeve 2. A lamp with its pins 4, sliding along the groove, is immersed in the coupling 1 until it stops with the petals 3, then rotated a quarter of a turn by sliding the pins 4 already along the groove 6 until it stops. In this case, the springy petals 3 provide a reliable contact power transmission.

 The coupling 1 has a wide two grooves 9 (Fig.5 section BB and Fig.6 section BB).

 Thanks to the grooves 9, a window 10 is formed in the hollow sleeve (Fig. 3), through which the contacting of the conductive elements can be visually monitored.

 The cartridge assembly ends by screwing the sleeve (all the way) onto the sleeve 1 from the side of the conductive wires for both one and the other type of cartridges.

 The assembled cartridge for lamps with a pin base is shown in figure 1.

 An assembled cartridge for lamps with a screw cap is shown in FIG. 2. In this case, instead of the grooves 5 and 6 (FIG. 1), a thread is applied in the sleeve 1 (FIG. 2) according to the pitch and thread profile of the bulb base. This is the only difference in the sleeve couplings with pin and screw connection.

 Any of the existing cartridges consists of three to four main parts: the coupling, the sleeve and the connecting parts of the coupling with the sleeve.

 In the prototype, verification of the reliability of assembly and contact with the lamp base is visually impossible, since everything is structurally closed.

 Checking the contact in the prototype is possible only functionally - by including in the power source a fully assembled cartridge with a bulb.

 In the claimed unified cartridge, the reliability of the assembly and contacting of the conductive elements is checked visually through the window 10, since the sleeve serving as a cover for the conductive elements of the coupling is screwed onto the already assembled visually and physically tested, ready-to-use coupling (Fig. 1,2).

 It should be noted that in conditions of safe contact with the environment, the coupling can be used without a sleeve, i.e. serve independently as a cartridge.

 From the above shows the great advantage of the claimed cartridge in the manufacture, operation and reliability of it and how relevant for the industry the claimed invention.
