Definitions
- Intermediate plugs in particular electrical ones, are known. They regularly serve to connect incompatible plugs and / or sockets or they have circuit elements such as Switches or filters and the like on.
- An adapter plug according to the preamble of claim 1 is known from US-A-3058089.
- a control cable for flash synchronization is commercially available provided with a plug that plugs into a socket on the Part of the camera containing the shutter, the housing or the Lens that is plugged in. It is bipolar Coaxial plugs and sockets, where the mechanical Connection by the friction of the touching in the fit electrical contact elements is effected.
- the task of the innovation is the mechanical connection between a plug and a socket to improve in particular to increase the holding force.
- an adapter plug according to claim 1 a socket with a hollow cylinder and with a plug with Outer cylinder with protruding locking lug, characterized in that the plug and socket are designed to match one another and the hollow cylinder has a clamping device.
- the innovation shown in longitudinal section in Figure 1 Intermediate plug 1 is for interaction with plugs and Couplings for the flash synchronization control line from Commonly used cameras, especially according to the DIN standard 19003.
- the adapter plug 1 consists of a Socket B and a plug S.
- the hollow cylinder 13 forms the mechanical contact surface and the electrical contact surface of the outer pole of the socket B. He can by a clamping screw 14 (13) and then the cylindrical one Clamp the pole piece of a suitable connector.
- the outer cylinder 11 forms the Plug S a common part 10.
- the outer cylinder 11 has as a detent cam 12 a circumferential elevation.
- a Insulating part 16 is in the middle of part 10 of pin 15 with the Hollow cylinder 152 on the socket side (B) and the contact pin 151 inserted on the connector side (S).
- the hollow cylinder 13 In the area of the hollow cylinder 13 is on the insulating part 16 Pressed metal sleeve 17. On the one hand, this clamps the pin 15 firmly in the insulating part 16 and secondly supports the outer pole from a plug, which in the hollow cylinder 13 if necessary is jammed.
- the hollow cylinder 13 can be repeated several times be slotted, as is usual with collets, in order to clamp facilitate.
- FIG. 2 shows schematically in section the connector part S of Intermediate plug 1 inserted into a socket 211.
- This socket 211 largely corresponds to the socket part B of the adapter plug 1 or a socket according to standard DIN 19003.
- an elastic (rubber) Ring 214 In a groove of the hollow cylinder 213 is embedded an elastic (rubber) Ring 214.
- an insulating piece 216 With an insulating piece 216 is the hollow cylindrical Internal contact 252 fixed in the socket 211.
- Socket 211 is commercially available in camera lenses with a central shutter from the Carl Zeiss company.
- the hollow cylinder 213 of the bush 211 is in friction mechanical (fit) and in electrical contact with circumferential locking cam 12 of the intermediate connector 1.
- the elastic Ring 214 is located on the rear part of the outer cylinder 11 and the circumferential locking cam 12 and thus forms a locking connection of socket 211 and adapter plug 1, their holding force is much higher than that of the usual fit, even if the rubber ring 214 in the bush 211 ensures increased friction, which, on the other hand, can also be easily solved by hand.
- the Clamp connection of the socket part B of the adapter plug 1 with An inserted connector is designed so that the holding force much higher than that of the snap connection of the adapter plug 1 and socket 211, so that in routine handling to connect and disconnect socket 211 and cable with the existing plug of the adapter plug 1 remains reliably connected to the plug and cable.
- the adapter plug 1 is also in each standard-compliant socket without Insertable rubber ring, full compatibility with standard parts is given.
- a camera 2 consisting of housing 22 and lens 21 with Central shutter 212 carries on the lens 21 a socket 211 according Figure 2, to which the flash synchronization signal is present.
- a Flash unit 3 (electron flash) is using known means mechanically connected to the camera 2 and has a connection cable 31 with connector 311 according to standard DIN 19003. This connector is 311 clamped in the intermediate connector 1 and the intermediate connector 1 is engaged according to Figure 2 in the socket 211 on the lens 21. The cable connection from the camera 2 to the flash unit 3 is thus reliably secured against accidental separation.
- an adapter plug according to the innovation is not based on the dimensioning and use according to the example the photo technology is limited. Others, including multipoles, Connector formats and e.g. Versions as optical fiber coupling are also possible.
- the holding force is by the new plug according to the innovation increased by a locking cam on the adapter in cooperation with the elastic Element of an element of the plug / socket pair a snap connection creates and the other element on the adapter is clamped.
