Abstract

The utility model belongs to a power socket which comprises a power jack 1, a panel 3, and a socket body 6 which is fixed with the panel 3. Each electrical contact which is installed on the socket body 6 is respectively composed of two contact plates, and at least one of the two contact plates is a movable contact plate. A backpressure spring is installed between the back of each movable contact plate and the socket body 6, and each electrical contact is in close contact with a plug through the backpressure spring. The back end of each movable contact is fixedly connected with a wiring plate 4 into one body through a soft wire. The socket has the advantages of large contact surface, favorable electrical conductivity, reliable operation and application safety.

Description

The face contact type socket

The utility model belongs to electric equipment products, the socket that specifically a kind of power supply connects.

At present, production and the supply socket of using have many types, and they can be divided into single-phase two pole sockets, single-phase three pole sockets, wall type socket, multi-function jack etc.No matter be the sort of socket, its contact all is the U-shaped structure made from the metal copper sheet, and the elasticity by the metal copper sheet reaches the purpose that closely contacts with metallic plug.This receptacle connector that is processed by copper sheet is actually and is difficult to reach face contact with attaching plug, and only linear contact or the contact of some property.Because the real contact area between attaching plug and the socket is less, when power supply by the time, will increase the resistance of circuit, attaching plug and socket are generated heat, even can produce electric spark or it is burnt.In addition, the copper sheet contact of this conventional electrical outlet, after using a period of time, its self elasticity can reduce, and the contact performance between the attaching plug can further reduce, and the resistance of contact position can further strengthen, its heating phenomenon can be more serious, thereby can cause the socket insulating material aging, can shorten the useful life of socket, reduce the fail safe of electricity consumption.

The purpose of this utility model be to provide contact-making surface between a kind of supply socket and the plug big, conduct electricity very well, reliable operation, supply socket safe in utilization.

The purpose of this utility model is to realize like this, it includes the panel of charged source jack, and with this panel fixed installation all-in-one-piece socket, its technical essential is: each electrical contact that is installed on the socket is formed by two contact plate, at least one contact plate is the movable contact plate, the back pressure type spring is installed between the back side of its movable contact plate and the socket, and the pressure of this spring of process makes the plug that inserts between two contact plate closely contact with two contact plate.Between the rear end of movable contact plate and terminal block through the flexible conductor formation that is connected to one.

Because the utility model has become the U type structure of former receptacle connector into two contact plate, the contact force between its socket and plug has become the elastic force effect by spring by self elastic force of former U type contact, makes that the contact force between the socket and plug increases.Moreover the rear end of movable contact plate is connected with terminal block through flexible conductor, guaranteed that movable contact can contact by realization face with plug, just increase the contact area between the two, reduce the resistance of contact position, thereby overcome supply socket and generate heat, produce bad phenomenon such as electric spark easily, also improve electric conductivity, prolonged useful life of socket, ensured the fail safe and the reliability of electricity consumption.

Fig. 1 is the structure principle chart of the utility model two pole sockets;

Fig. 2 is the B-B cutaway view of Fig. 1;

Fig. 3 is the structure principle chart of the utility model three pole sockets;

Fig. 4 is the A-A cutaway view of Fig. 3.

Below in conjunction with accompanying drawing the utility model is elaborated.

The panel 3 of this socket is the baffle of socket, according to made socket shape, can make rectangle, square, circle etc.Panel 3 is provided with jack 1, so that plug passes.Panel 3 is fixed as one with the socket 6 that electrical contact is installed, and its fixed form can connect with bolt 2, also can be as shown in Figure 2, and with being threaded etc.Each electrical contact that is installed on the socket 6 is made of two contact plate, at least one contact plate is the movable contact plate, between its movable contact backboard face and the socket 6 the back pressure type spring is installed, and is connected to one through flexible conductor between the rear end of movable contact plate and the terminal block.With reference to Fig. 2, electrical contact can be made three kinds of forms: one, two of this socket electrical contacts all can be shown in that electrical contact of the right, constitute by fixed contact plate 12 and movable contact plate 9, between the back side of its movable contact plate 9 and the socket 6 spring 10 is installed, and between movable contact plate 9 and terminal block 4, is connected to one through flexible conductor 11.Two, two electrical contacts on the socket also can be shown in that electrical contact of the left side, constitute by movable contact plate 9 and left movable contact plate 8, between left side movable contact plate 8 and the socket 6 right spring 7 is installed, between movable contact plate 9 and the socket 6 spring 10 is installed, left movable contact plate 8 and movable contact plate 9 are respectively through left flexible conductor 5, flexible conductor 11 and terminal block 4 formation that is connected to one.Three, two of this socket contacts also can be made above two kinds of versions respectively, promptly have single contact that starts to levy contact and a Dual Action plate contact formation.

The terminal block 4 of this socket can be located at the bottom of socket 6, also can be located at the top of socket 6.

This socket can be made two pole sockets, also can make three pole sockets, can also make the multi-function jack or the wall socket of multiple jack.

The movable contact plate 9 and the fixed contact plate 12 of this socket can be made plate armature, also can make arc, to be suitable for different plugs.Jack on its panel 3 can be a slot, also can be circular hole or combination bore.
