Abstract

A rapid jointing device for a power cord and an electrical apparatus is characterized in that the electrical apparatus is provided with a base for the cutting graftage of the power line and provided with a first contact and a second contact both of which are used for controlling guiding state and the second contact is sharp-pointed; the base is provided with a groove holding the two contacts and the power line and the base is also provided with a pressing block which inserted into and assembled with the base. When assembled on the base, the pressing block simultaneously presses the power line on the first contact and the second contact to make the two sharp-pointed contacts break through the insulated layer of the power line to be contact with a copper line. By the device, the power line can directly insert into and connected with the first contact and the second contact of the electrical apparatus without the insulated stripping the power line, and besides the device does not need tools and is convenient for inlaying grafting operation.

Description

The quick coupling device of power line and electrical appliance

(1) technical field:

The utility model relates to the quick coupling device of a kind of power line and electrical appliance, and it is not needing under the situation that outer field insulator divests with power line, promptly can apace power line be engaged and be fixed on the appliance switch.

General home-use power line is to coat one deck insulating barrier outside copper wire, when desire is plugged on power line on the appliance switch, needs the insulation displacement with mains terminals, exposes copper cash, again copper cash is fixed or is plugged on the appliance switch.

(2) background technology:

In order to clearly demonstrate the inserting mode of existing power supply line, be example with lamp socket shown in Figure 6 50, lamp socket 50 comprises seat 51 in, is coated on upper encloser 52, lower encioser 53 outside the interior seat 51; Interior seat 51 is positioned at the inside of upper encloser 52, one end is a plastic insulating base 510, be positioned at the socket end 511 of the other end for making of lower encioser 53 inside by electric conductor, in order to the bulb 70 that is spirally connected, on interior seat 51, be provided with first contact 512, second contact 513 that can conduct electricity in addition, seat 51 in first contact 512 is piercing in, center one end of connection socket end 511 inside is to connect the central contact of bulb 70; Second contact then connects socket end 511, be assembled with a switch 514 on the interior seat 51, power line 60 comprises two copper cash 62, be coated with green extremely layer 61 outside two copper cash 62 respectively, normally the centre of two insulating barriers 61 is connected slightly and form invaginated type, when desiring socket power line 60, be after the insulating barrier 61 of end is peeled off, expose copper cash 62, again two sections copper cash 62 are plugged in first, second contact 512,513, utilize toggle actuator 514 again whether to switch first contact 512,513 conductings of second contact.

Above-mentioned lamp socket 50 structures that are existing in order to assembling bulb 70, from the above, when desire is plugged on power line 60 on the interior seat 51, need peel off insulating barrier 61 earlier, just can expose copper cash 62, again copper cash 62 is plugged in by switch 514 controlled first, second contact 512,513, but such grafting process too bothers, and, when peeling off insulating barrier 61, easily with copper cash 62 pinch ofves, and when one copper cash 62 breaking degree wherein serious and can not use the time, twice copper cash 62 all needs to block and divests insulating barrier 61 again, like this, the twice copper cash 62 of power line 60 could keep isometric, and operation is extremely inconvenient.

(3) summary of the invention:

Main purpose of the present utility model is to provide the quick coupling device of a kind of power line of being convenient to operate and electrical appliance.

For achieving the above object, the utility model is taked following technical measures:

The quick coupling device of power line of the present utility model and electrical appliance, has the pedestal that a power supply source line is pegged graft on the electrical equipment, pedestal is provided with first contact, second contact of control conducting state, and comprises the twice copper cash in order to the power line that is arranged in two point, and copper cash is coated with insulating barrier; Also comprise one can with the pedestal pressing block of insert group mutually;

Pedestal be provided with one can ccontaining power line groove, be fixed in the groove to first, second contact separation, two point lays respectively at the twice copper cash position corresponding to power line, the free end of two point is cone-shaped; At least one end of groove is through to the perisporium of pedestal;

Pressing block lid overlays on the groove of pedestal, and pressing block is equipped with one to be enough to suppress power line and to make cone-shaped two point wear out insulating barrier and touch the skewback of copper cash towards the side of groove.

Wherein: the other end of described groove is arranged with the slot that a power supply source line free end is planted towards the pedestal inboard.
