Abstract
The utility model relates to a power supply outlet with a connecting foot for detection. The utility model is formed by the method that a metal casing body is packed on a rubber core, power supply terminals are arranged in the rubber core to form a power supply outlet. The utility model is characterized in that a terminal seat is arranged behind the rubber core, two sets of power supply terminals and a set of detecting terminals with shorter length than the power supply terminals are inserted in the terminal seat, and the power supply terminals and the detecting terminals are positioned in jacks of the rubber core. The power supply terminals are contacted with a power supply to enable tiny current to be shunted to the detecting terminals according to the structure in the process of enabling a power supply plug to be inserted in the power supply outlet. If one set of the two sets of power supply terminals takes place abruption, the tiny shunt of the detecting terminals are jumped, a power supply is cut off, and thus, the utility model has a good electric supply effect.
Description
Technical field
The utility model relates to a kind of supply socket, refers to a kind of carry-on electrical equipment supply socket especially.
Technical background
General carry-on electrical equipment, as walkman, mobile phone ... Deng, for making above-mentioned various carry-on electrical equipment be connected external power supply, usually must install supply socket on the electrical equipment with oneself, the side must connect the plug-in mounting power line, just must charge or directly use external power source and known supply socket for carry-on electrical equipment, after it connects attaching plug, the power supply of being imported by attaching plug can be imported the circuit of electrical equipment via supply socket, so can supply electrical equipment needed power supply; But after attaching plug one was inserted in the supply socket, power supply promptly directly was supplied to electrical equipment, if when the circuit of electrical equipment has unknown cause to damage, this moment, directly circuit was given in power supply, then may cause the circuit damage and caused the unpredictable damage of electrical equipment.
The inventor is thoughts on the above-mentioned disappearance of known supply socket, thereby sets about design, designs the supply socket of a kind of tool detecting with pin eventually.
Summary of the invention
Main purpose of the present utility model, aim to provide a kind of supply socket, it has the detecting terminal that two groups of power supply terminals and a group length are shorter than power supply terminal, must be behind attaching plug socket power socket, this power supply terminal shunting Weak current is given the detecting terminal, if in two groups of power supply terminals one group open circuit, small minute electric current then detecting terminal jumps, promptly stop power supply, to reach preferable power supply effect.
The purpose of this utility model is achieved in that
The detecting of a kind of tool lies in a glue heart external packing one metal shell with the supply socket of pin, and at the intracardiac power supply terminal that is equiped with of glue to form supply socket; It is characterized in that: this glue heart rear is equiped with a terminal base, is fitted with the detecting terminal that two groups of power supply terminals and a group length are shorter than power supply terminal on this terminal base, and this power supply terminal and this detecting terminal position is in the jack of this glue heart.With this this attaching plug is pegged graft in the process of this supply socket, this power supply terminal contacts power supply earlier Weak current is shunted to the detecting terminal, if one group is opened circuit in two groups of power supply terminals, small minute electric current then detecting terminal jumps and promptly stops power supply, with in order to detect.
Advantage of the present utility model and good effect are: because its supply socket has the detecting terminal that two groups of power supply terminals and a group length are shorter than power supply terminal, must be behind attaching plug socket power socket, this power supply terminal shunting Weak current is given the detecting terminal, if one group is opened circuit in two groups of power supply terminals, small minute electric current then detecting terminal jumps and promptly stops power supply, and therefore has preferable power supply effect.

Embodiment
For making the utility model clear and definite more full and accurate, cooperate following each accompanying drawing to describe in detail as the back now:
At first consult Fig. 1 and Fig. 2, the utility model lies in a glue heart 1 external packing one metal shell 2, and is equiped with power supply terminal 3a, 3b to form supply socket 10 in the glue heart 1: its feature is to be:
This glue heart 1 rear is equiped with a terminal base 4, and be fitted with two groups of power supply terminal 3a on this terminal base 4, a 3b and a group length are shorter than power supply terminal 3a, the detecting terminal 5 of 3b, and this power supply terminal 3a, 3b and 5 of terminals of detecting are in the jack 11 of the glue heart 1: make in the process of this attaching plug (expression in graphic) socket power socket 10, this power supply terminal 3a, 3b contacts power supply earlier Weak current is shunted to detecting terminal 5, if two groups of power supply terminal 3a, one group is opened circuit among the 3b, small minute electric current then detecting terminal 5 jumps, promptly stop power supply, thereby preferable power supply effect must be arranged.
According to above-mentioned structure, because the power supply terminal 3a that uses in order to the connection power supply except installing in the glue heart 1 of this supply socket 10, outside the 3b, be fitted with detecting terminal 5 simultaneously in order to detecting load (circuit), after attaching plug inserts supply socket 10, because this power supply terminal 3a, 3b shunting Weak current is given detecting terminal 5, if two groups of power supply terminal 3a, one group is opened circuit or loose contact among the 3b, small minute electric current then detecting terminal 5 jumps, so can (this be the emphasis of this creation to be used for controlling power supply circuits as signal by the electric current that jumps, do not give unnecessary details in this), make power supply circuits stop power supply to load, avoid power supply in the time of so can damaging in order to protection load (circuit) contingency, preventing that the situation that load (circuit) damages from enlarging, thus preferable protection effect arranged; Otherwise, if load (circuit) but operate as normal then can use for load (circuit) by power supply terminal 3a, 3b normal power supply.
In sum, structure disclosed in the utility model is in the past not have, and can reach above-mentioned effect really, and reason has possessed the important document of novel patent, and novel patent is filed an application in the whence in accordance with the law.
