Description

Temperature control electromagnetic lock

Technical field

The utility model belongs to new-energy automobile charging field, be related to it is a kind of for inside charging gun with high temperature protection The electromagnetic lock of function.

Background technology

Charging gun in charging process, by the set of its internal electromagnetic lock and reset controlling charging gun in charging pile or Locking or released state at charging electric vehicle end, in the course of the work electromagnetic lock can be made because of its internal coil current heating Into coil line heating, but persistent fever can not only be damaged and will burn electromagnetic lock, and can because temperature is too high and caused by Circuit damage, ultimately causes the greater losses such as charging gun is damaged or entirety is scrapped.

Utility model content

The purpose of this utility model is to provide a kind of temperature control electromagnetic lock with high temperature protection function.

To achieve the above object, the utility model provides a kind of temperature control electromagnetic lock, including shell, control coil, electromagnetic lock Core and temperature detect switch (TDS).Control coil is arranged in shell, and temperature detect switch (TDS) is connected on same circuit with control coil, temperature detect switch (TDS) It is fixed on electromagnetic lock with electromagnetic lock core.

Preferably, the temperature detect switch (TDS) is temperature protection switch.

Preferably, the temperature detect switch (TDS) is fixed on electromagnetic lock side by draw-in groove.

Preferably, the temperature detect switch (TDS) is fixed on electromagnetic lock shell by bonding agent.

As described above, the utility model temperature control electromagnetic lock realizes that electromagnetic lock is high by the temperature detect switch (TDS) connected with control coil Warm automatic disconnection work and low temperature automatic opening work such that it is able to effectively solve charging gun and cause because of electromagnetic lock continued power Overheat, damage, scrap and the problems such as energy loss, and, the utility model temperature control electromagnetic lock has simple structure, cost Low, reliable the advantages of.

Brief description of the drawings

Fig. 1 is the dimensional structure diagram of the utility model temperature control electromagnetic lock.

Specific embodiment

To describe technology contents of the present utility model, structural feature, the objects and the effects in detail, below in conjunction with implementation Mode simultaneously coordinates accompanying drawing to be explained in detail.

Fig. 1 is referred to, the utility model temperature control electromagnetic lock includes shell 1, control coil 2, electromagnetic lock core 4 and temperature detect switch (TDS) 3。

Control coil 2 is arranged in shell 1.Temperature detect switch (TDS) 3 and electromagnetic lock core are fixed on electromagnetic lock.Temperature protection switch 3 it is parallel be fixed on electromagnetic lock, temperature protection switch 3 and control coil 2 are connected on same circuit.

In the present embodiment, temperature detect switch (TDS) 3 is temperature protection switch.

When control coil 2 because lasting energization causes temperature too high（Reach a high temperature threshold value）When, connected with control coil 2 Temperature protection switch 3 disconnects automatically, and now, the no current of control coil 2 passes through, the reduction of control coil natural heat dissipation temperature, works as control The temperature of coil processed 2 as little as low temperature threshold when, temperature protection switch 3 automatically close, the normal power-up of control coil 2 work.

Above procedure reciprocation cycle, so as to realize protecting the purpose of electromagnetic lock.

In sum, the utility model temperature control electromagnetic lock realizes electricity by the temperature protection switch 3 connected in control coil 2 Magnetic padlock high temperature disconnects work, low temperature automatic opening work automatically such that it is able to effectively solve charging gun because of electromagnetic lock continued power And cause overheat, damage, scrap and the problems such as energy loss, and, the utility model temperature control electromagnetic lock have simple structure, Low cost, it is reliable the advantages of.

The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art can also make accordingly Various changes, but any be equal to the utility model or similar change should all cover model in the utility model claim In enclosing.
