Abstract
The utility model relates to a connector, especially to a heavy current connector, which is a connecting jack adaptive to the heavy current working condition. The connecting jack has large contact area, small contact resistor, and little heat generation. The heavy current connector comprises a plug and a socket. The socket is composed of a jack body seat and a jack body and is characterized in that a wire pressing cone is arranged in the jack body seat; a stepped circular slot is arranged on the front end of the jack body seat; the jack body is composed of a spring ring, a metal wire conductive inserting ring and a sheath; the inner wall of the sheath is an installing slot which can hold the spring ring to sleeve on the metal wire conductive inserting ring; the spring ring is sleeved outside the metal wire conductive inserting ring; the front and back ends of the spring ring are shorter than the metal wire conductive inserting ring; the front end of the spring ring is a trumpet-shaped inserting slot and the tail end of the spring ring is inserted into the stepped circular slot of the jack body seat and is fastened with a plug pin through a sleeve loop. The utility model has the advantages of enhancing the contact area of the inserting pin so as to decrease the thermal value of the contact surface.

The utility model relates to a kind of connector, and particularly a kind of high current connector belongs to the connector in the appliance field.
Background technology
Connector is widely used in appliance field, and it is often used in the electric equipment, belongs to a kind of connector.In the prior art, connector is made of plug 1 and socket 2.Socket 2 as shown in Figure 1, this socket 2 adopts machine work moulding usually.The structure of described socket 2 is made of receptacle body seat 21 and receptacle body 22 two parts, and the oral area of the front end of receptacle body 22 is formed to a chamfering usually, so that easily plug is inserted.Receptacle body vertically is divided into several sheets, so that receptacle body is inwardly shunk, contacts with plug better.The defective of this socket is: the contact site of receptacle body and contact pin for " dotted line " contact, promptly for the longitudinal profile of contact pin, is a contact; For the circumference of contact pin, be the line contact.So connector contact-making surface of the prior art is little, contact-making surface pressure is big; Contact pin, jack contact surface coating wear and tear easily, cause shortening in useful life, contact resistance instability etc.This connector only is fit under the little current work environment ring.But for the operational environment of big electric current, this connector is not suitable for.
The utility model content
The purpose of this utility model is: a kind of connection jack that is fit to big current work condition is provided, and this contact area that connects jack is big, and contact resistance is little, and it is little to produce heat.
The utility model is achieved in that a kind of high current connector, comprises plug 1 and socket 2, and described socket 2 is made of receptacle body seat 21 and receptacle body 22; It is characterized in that: also be provided with line ball cone 211 in the described receptacle body seat 21, the front end of receptacle body seat 21 is provided with the stairstepping circular groove; Described receptacle body 22 is made of spring coil 221, wire conduction insertion circle 222 and sheath 223, and the inwall of described sheath 223 is can hold spring coil 221 to be enclosed within the mounting groove 2231 that the wire conduction is inserted circle 222; Described spring coil 221 is enclosed within the outside that the wire conduction is inserted circle 222, the rear and front end of spring coil 221 all is shorter than the wire conduction and inserts circle 222, wherein front end is horn-like insertion mouth, and tail end inserts the stairstepping circular groove of receptacle body seat 21, and fixes by lasso 224 and plug pin;
Described wire conduction is inserted circle 222 and is made of vertical arrangement of some one metal wires.
Described line ball cone 211 is divided into two ends, and an end is provided with external screw thread and inner hexagonal hole, and the top of the other end is a cone.
Be provided with screw thread in the hole of described receptacle body seat 21, the threaded engagement of this screw thread and line ball cone 211.
Anterior sidewall in receptacle body seat 21 holes is provided with protuberance 212, and the cross section of this protuberance 212 is triangular in shape, and its inwall constitutes an internal tapered hole, and this internal tapered hole cooperates with the cone on line ball cone 211 tops.
Invention effect of the present utility model is: increase the contact area of inserting pin, thereby reduce the caloric value of contact-making surface.
