SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves of embodiment is that current electric connector's jack can't guarantee area of contact's maximize under the condition of guaranteeing less volume and plug power, and the technology is fit for mass production simultaneously and uses.

In order to solve the above technical problem, the utility model discloses a technical scheme that embodiment adopted is: there is provided an electrical connector jack comprising: a sleeve and a contact coil; a plurality of welding points are arranged inside the sleeve, and the contact coil is coaxially fixed inside the sleeve through the welding points; or a plurality of welding points are arranged outside the sleeve, and the contact coil is coaxially fixed outside the sleeve through the welding points; the contact coil is made by continuously bending a whole metal wire.

The sleeve is cylindrical, and the welding points are distributed between the sleeve and the contact coil.

The contact coil comprises a plurality of metal wires which are closely arranged, and the metal wires are obliquely arranged in the same direction.

Wherein the inclination angle of the metal wire ranges from 5 degrees to 60 degrees.

Wherein the cross section of the metal wire is in a shape of a circle or an ellipse

For making technical scheme perfect, the utility model discloses embodiment still provides an electric connector, including the plug with the electric connector jack.

The utility model discloses embodiment's beneficial effect is: be different from prior art's condition, the utility model discloses embodiment makes contact coil through buckling in succession a whole metal wire after making it be same direction slope and closely arrange, is fixed in sleeve inside or outside through the welding point with contact coil simultaneously for the electric connector jack guarantees area of contact's maximize under the condition of the same volume and less plug power, thereby satisfies the demand that stably bears high voltage and heavy current.
