Abstract

The utility model belongs to the connecting field of the electric conduction, and relates to a comb-shaped spring leaf core socket, comprising a socket shell body and a socket core. The socket shell body is divided into two or three independent cabins. Each cabin is provided with a jack. The zero line, the ground line or the live line socket core are respectively arranged in each independent cabin. The bottom of the socket core is respectively connected with a line connecting column through a conducting line. The socket core forms a double return bidirectional concave shape. The contact face of the socket core is a comb-shaped spring leaf, and is the plane surface or the cambered surface. The included angle of the guide surface of the socket core and the side wall of the socket core is 45 DEG. The included angle of the guide surface and the contact face is 138 DEG. The included angle of the side wall of the socket core and the bottom of the socket core is 88 DEG. The utility model basically eliminates the calorific problem of the socket caused by the bad contact, has the advantages of large current carrying capacity, good contact and safe use, and has strong compatibility on different plugs and low increase of the cost.

Description

Comb shape shell fragment seat core socket

One, technical field the utility model belongs to the connection area of conductivity, particularly relates to the socket of a kind of family expenses and similar applications.

Two, the existing socket seat core of background technology mostly is the U-shaped single layer structure, plug is a dotted-line style with seat core contact-making surface, contact area is less than 3 square millimeters, cause the metal clips distortion after working long hours easily, the plasticity and the elasticity of metal clips are weakened, cause plug and socket loose contact, when electric current is big, give birth to heat easily, form oxide layer on the surface, cause resistance to increase, living thermal phenomenon is more obvious, thereby forms vicious circle, the copped wave meeting that loose contact produces forms the hard pulse electric current, can cause in various degree harm to most electrical equipment.

Three, summary of the invention the utility model provides a kind of comb shape shell fragment seat core socket, substantially having eliminated loose contact causes socket to give birth to the problem of heat, it comprises Socket casing and seat core, Socket casing is divided into independently cabin of 2 or 3, each cabin is provided with jack, zero line, ground wire or live wire seat core branch are located at each independently in the cabin, seat core bottom is connected with binding post respectively by lead, the seat core is two two-way spills of returning, and seat core contact-making surface is the comb shape shell fragment, and is plane or cambered surface, seat core approaching face is 45 ° with seat core sidewall angle, approaching face and contact-making surface angle are 138 °, and sidewall is 88 ° with a seat core bottom angle, and it is big to have a current carrying capacity, contact is good, characteristics safe in utilization, and stronger to the compatibility of different plugs, and the increase of cost expense is seldom.

Four, description of drawings Fig. 1 is the utility model cross-sectional view;

Fig. 2 is the utility model contact-making surface planar structure schematic diagram;

Fig. 3 is the utility model contact-making surface globoidal structure schematic diagram.

Five, embodiment is below in conjunction with Fig. 1, Fig. 2 and Fig. 3 are further described the utility model, it comprises Socket casing 1 and seat core 3, Socket casing 1 is divided into independently cabin of 2 or 3, each cabin is provided with jack 2, zero line, ground wire or live wire seat core were located at each in 3 minutes independently in the cabin, seat core bottom flexibly connects with binding post 6 respectively by lead 7, seat core 3 is two two-way spills of returning, seat core contact-making surface is the comb shape shell fragment, and be plane or cambered surface, seat core 3 approaching faces 4 are 45 ° with seat core sidewall angle, and approaching face 4 is 138 ° with contact-making surface 5 angles, and sidewall is 88 ° with seat core bottom angle.
