In order to deal with the situation of connection and disconnection, solve unnecessary troubles brought by the prior generation products in the using process and reduce the potential safety hazard, an electric heating card type anti-pulling connector needs to be developed urgently.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present invention provides an electric heating card type anti-pulling connector for connecting an electric blanket and an electric blanket controller, facilitating separation/connection of the electric blanket and a power supply controller, and being simple and convenient to connect and not easy to drop.

In order to achieve the above object, the utility model adopts the following technical scheme to achieve the above object:

an electric heating card type pull-proof connector comprises a female plug and a male plug, wherein the male plug is provided with a plurality of male pins, the female plug is provided with a plurality of jacks, and the male pins and the jacks are correspondingly plugged one by one; the male plug is provided with a positioning bulge parallel to the male pin, the female plug is provided with a groove parallel to the jack, and the bulge and the groove are correspondingly spliced; barbs are arranged on the inner walls of the two sides of the male plug respectively, and clamping wings are arranged on the two sides of the female plug respectively; one end of the clamping wing is fixed on the female plug, and the other end of the clamping wing extends backwards in an inclined mode; the joint wing middle part is equipped with the joint portion that is used for corresponding the joint with the barb, the free end of joint wing is for pressing the splenium.

Preferably, the protrusions have a triangular prism shape.

Preferably, the barb and the male insertion inner wall form an included angle of 45 degrees.

Preferably, an included angle of 45 degrees is formed between the clamping portion and the clamping wing.

Preferably, the number of the male pins and the number of the jacks are four. The contact of the male pin and the jack is stable, and good conduction performance is guaranteed.

Preferably, a certain included angle is formed between the clamping wing and the outer wall of the female plug. More preferably, the included angle is 15 ° to 45 °.

Two clamping wings with clamping parts are added to two sides of a female plug of an electric blanket, a barb is designed at the corresponding position of two inner side surfaces of a shell of a male end of the electric blanket, when the female plug is pushed into the male shell, the clamping parts of the female plug are embedded into the barb of the male shell to form a buckle, the female plug is prevented from falling off, when a connector is required to be separated, a pressing part of the clamping wings on two sides of the female plug is pressed lightly, the buckle state can be withdrawn by pulling, and the female plug is separated easily.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses when keeping original function (functions such as switch, control by temperature change and timing), it is convenient to connect, one inserts the usefulness, and a key separation, the trouble of bringing of the separation that drops of solution connector that can be fine prevents to take off the potential safety hazard that causes because of female inserting.
