Abstract

The utility model discloses a power supply adapter, it is including shell (1), base (2), socket (3) and wiring board switch (4), socket (3) dress is on base (2), wiring board switch (4) and socket mouth are established on shell (1), shell (1) closing cap is on base (2), socket (3) are through the wire through wiring board switch external power supply line, temperature controller (5) are equipped with to the position of being close wiring board switch (4) on base (2), temperature controller (5) are connected between wiring board switch (4) and socket (3). The utility model has the advantages of as follows: supply interruption when operating temperature reaches the peak has guaranteed that power supply adapter connects the safety of circuit after with, and the switch -on circuit has been guaranteed the circuit and is normally worked when operating temperature returns to normal the temperature.

Description

A kind of power-supply adapter

Technical field

The utility model relates to electrical technology field, is specifically related to a kind of power-supply adapter.

Background technology

People recognize the importance of electrical safety gradually, but it is overheated also may to there is the power-supply adapter that following several reason causes, and cause electrical safety accident, even fire:

1, power-supply adapter surprisingly covers by indivedual user, causes heat radiation bad.

2, accidental short circuit, causes heating.

3, the heating that causes is transshipped.

Chinese patent literature CN101494345A discloses a kind of power patch panel with overtemperature protection on July 29th, 2009, it comprises shell, socket, detection alarm module, terminal block switch and base, wherein: socket and terminal block switch are set in turn on shell, shell and the clamping of base phase, detection alarm module installation is on base and pass through chassis ground, one end of terminal block switch is connected with detection alarm module with socket, the other end of terminal block switch is connected with the power patch panel plug of housing exterior, although this terminal block gives the alarm in real time when the working temperature of power patch panel reaches or exceed the highest permission working temperature, user of service is reminded to note, but it can not direct deenergization, occur to prevent electric accident.

Utility model content

For existing power supply terminal block Problems existing, technical problem to be solved in the utility model is just to provide a kind of power-supply adapter, it can be cut off the electricity supply when working temperature reaches peak, ensure the safety of power-supply adapter and rear connection circuit, connect circuit when safe temperature range, ensure that circuit normally works.

Technical problem to be solved in the utility model is realized by such technical scheme, it includes shell, base, socket and terminal block switch, socket is contained on base, terminal block switch and socket port are located on shell, shell is sealed on base, socket through terminal block switch circumscripted power line, base is equipped with thermostat close to the position of terminal block switch by wire, and thermostat is connected between terminal block switch and socket.

Because thermostat is positioned at before socket connects load; when the load of thermostat is excessive or ambient temperature raises; the operating temperature of thermostat is made to reach its limit value; thermostat deenergization; protect power-supply adapter and rear connection circuit; when temperature return is to safe temperature, thermostat connects circuit, and circuit is normally worked.

So the utility model has following advantage: cut off the electricity supply when working temperature reaches peak, ensure that the safety of power-supply adapter and rear connection circuit, connect circuit when working temperature recovers normal temperature, ensure that circuit normally works.

Accompanying drawing explanation

Accompanying drawing of the present utility model is described as follows:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is circuit interconnect pattern of the present utility model.

In figure: 1. shell; 2. base; 3. socket; 4. terminal block switch; 5. thermostat; 6. power supply indicator; 7. overtemperature alarm lamp.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1, the utility model includes shell 1, base 2, socket 3 and terminal block switch 4, socket 3 is contained on base 2, terminal block switch 4 and socket port are located on shell 1, shell 1 is sealed on base 2, socket 3 through terminal block switch circumscripted power line, base 2 is equipped with thermostat 5 close to the position of terminal block switch 4 by wire; As shown in Figure 2, thermostat 5 is connected between terminal block switch 4 and socket 3.

As shown in Figure 2, a power supply indicator 6 in parallel between the port of socket 3, power supply indicator 6 luminescence display circuit is logical, and socket 3 two ends are charged; R is the load from the access of socket 3 two ends; An overtemperature alarm lamp 7 in parallel at the two ends of thermostat 5, under normal circumstances, thermostat 5 communication line, overtemperature alarm lamp 7 is not luminous, and when working temperature reaches most ceiling value, thermostat 5 open-circuit line, overtemperature alarm lamp 7 luminescence produces alarm signal.Due to thermostat 5 open-circuit line, be equivalent to the resistance being connected in series a M Europe level in circuit, limit the electric current in circuit, can be enough to light power supply indicator, the power supply indicator 6 in circuit is still lighted.And the load R for rear end, be then " power-off " all do not react with electroprobe test.

Above-mentioned thermostat 5 selects KSD9700 thermostat, selects break-off signal scope 60 ± 5.0 DEG C by rated temperature specification, connects temperature range 40 ± 5.0 DEG C.

Claims
