Battery connection cable for electronic devices "

The innovation relates to a battery connection cable for electronic devices. In electronic devices, especially portable electronic devices, batteries are sometimes used which have two neberieinanderhaben.de poles on one side, which are designed in such a way that they can be plugged together with a corresponding connection line and corresponding contacts like a push button. The contacts of such batteries are designed so that \

if the battery needs to be changed, connect it to the connection cable only plugged together in a very specific polarity can be. In this way, the correct battery connection is inevitable, so that safe working of the electronic circuit is always guaranteed. For electronic circuits with integrated circuits it can happen that when changing the battery, even briefly touching the connection contacts with the wrong polarity Circuits can be destroyed. This can be avoided if a corresponding connection is made in a supply line

Protection diode is switched on. However, this diode expensive the device \ ": T and also has the disadvantage that the battery for the electronic Srhii ¹ hjn, unr7p.ii; iper is unusable because dig operating voltage is reduced for the electronic circuit to the Spannungsubfall across the diode? .

The innovation is based on the task of creating a safe VerpolungssLMutz to ensure the short-term Avoid touching the wrong contacts easily and safely when changing the battery. the The innovation is based on a 3-battery connection line. for electronic devices with one on their end attached contact holder for the battery connection contacts consisting of a plug contact and a socket contact, which have corresponding contacts The battery is plugged together and has been rewetted characterized in that the outside of the socket contact -; tes 5 in the contact holder 3 with an insulating layer which also includes the end faces is provided.

The innovation is to be explained in more detail below using an exemplary embodiment with the aid of FIGS will.

Figure 1 shows the arrangement to which the innovation relates

Figures 2 to 4 show details in section of the

ung n = ch Figure 1.

In Figure 1, a battery 1 is shown, which is connected to a connecting line 2 of the electronic Gel'dLfcib Vt! iuu iiüeti wci ücii bull ι Am ΙΚΓΞμΊ CiTiCT; end the line 2 has a contact holder 3 in which the contacts connected to the line 2 4, 5 are attached. The contacts 4, 5 are like a push button with corresponding contacts 6, 7 of the battery 1 plugged together, with the connections being mixed up due to the special shape of the contacts is not possible, so they are only in a particular Polarity can be plugged together. The plug contact 4 in the contact holder 3 is shown in the socket contact 6 with e.g. negative polarity of the baby 1 is inserted and the contact 7 with e.g. positive polarity of the battery 1 again in the socket contact 5 of the contact holder 3 Avoid accidental contact with the contacts and 6 it is proposed the socket contact 5 in the contact holder 3 on the outside with an insulating layer to provide. Different solutions for applying this layer are in section A-A in Figures 2, 3 and 4 shown.

In Figure 2, the socket contact B is cast in the contact holder 3, in which the line is also embedded. A shrink tube θ is drawn over the socket contact 5, which extends around it and also includes the upper end face. In this way, the plug contact 7 of the battery 1 with the plug contact 4 in the contact

bracket, but not the female connector Battery 1 can be brought into contact with the socket contact 5. A similar solution emerges Sü5 figur 3, in de in u ι Γι ü υ n b u (J i ι a υ 11 K υ 11 L d K L b Bin Ring 9 is paved, which also has the outer surfaces of the socket contact 5 and covers the upper edge.

Finally, FIG. 4 shows how the insulating protection is taken over by the contact holder 3, by the socket contact 5 is cast into this. It is of course also conceivable that the insulating sheath is pulled over the corresponding contact 6 of the battery 1.

Claims (1)

Claim to protection Battery connection cable for electronic devices with a contact holder attached to its end for the battery connection contacts consisting of a plug-in contact and a socket contact, which can be plugged together with the corresponding contacts of the battery in the manner of a push button, characterized in that the outside of the socket contact 5 in the contact holder 3 is provided with an insulating layer also encompassing the end faces.
