The utility model comprises a lamp base core body; a cavity is arranged in the lamp base core body; a wire clamping sheet is arranged in the cavity; a wire hole which is communicated with the cavity is arranged on the lamp base core body; a fixation hook is arranged beside the wire hole on the lamp base core body. The utility model has the advantages of quick wiring, easy wiring, firm connection of power cords, less possibility of looseness, no phenomenon of electric shock on surface and safe operation.

Description

The plug wire lamp base core

The utility model relates to a kind of plug wire lamp base core.

In existing lamp base core structure, lamp base core body upper surface is provided with binding post, and binding post is made of the electrode copper sheet and the screw of band screw, and power line and is fastened on the electrode copper sheet by screw around screw.Because in use, exist relative tearing between lamp holder and the power line, make power line produce in being connected of binding post place and become flexible with lamp holder, influence the transmission of power supply, burn out binding post easily.Said structure just seems very inconvenient for the connection of power lead, and wiring is slow, and the easy stripped thread of the wiring construction of stringing screw exists because the frequent pulling of power lead causes the phenomenon that gets loose.Having is exactly the surface that binding post is exposed at electrical equipment again, causes the danger of electric shock easily.

The purpose of this utility model is to provide a kind of wiring easy, firmly, is difficult for getting loose safe and reliable plug wire lamp base core.

For realizing the purpose of this utility model, described appliance switch comprises the lamp base core body, is provided with cavity in described lamp base core body, is provided with thread tension disc in cavity, and the line hole that communicates with cavity is arranged on the lamp base core body.

The drawing of accompanying drawing is described as follows:

Below in conjunction with accompanying drawing, the embodiment of the utility model plug wire lamp base core is described in further detail:

The plug wire lamp base core of embodiment 1 is as shown in Fig. 1,2, comprising lamp base core body 1, on lamp base core body 1, be provided with the electrode tongue piece 9 and mouthful circle 10 that link to each other with lamp holder, in described lamp base core body 1, be provided with two cavitys 2, in each cavity 2, be equipped with thread tension disc 3, thread tension disc 3 is electrically connected with a tongue piece 9 and a mouthful circle 10, on lamp base core body 1, is provided with cavity 2 to communicate, and the line hole 4 of receivability power line 11 insertions.Cavity 2 is flat-shaped, and described thread tension disc 3 is L shape bending and reclines and be arranged between the two side of flat-shaped cavity 2.The termination of thread tension disc 3 is provided with and can increases the groove 6 that contacts with the exposed portion of power line.When power line is inserted by the line hole, can be with the inside bending of thread tension disc, the groove of the thread tension disc end by bending can be clamped in the exposed portion of power line on the cavity sidewalls securely, good electrical connection effect is arranged, and the barb that the thread tension disc after the bending forms can block power line firmly, and the company's of making power line connects firmly.

The plug wire lamp base core of embodiment 2 is as shown in Fig. 3,4,5,6 and 7, comprising lamp base core body 1, the structure of the cavity 2 in the lamp base core body 1, thread tension disc 3, tongue piece 9 and mouthful circle 10 with implement identical in 1,4 sides, line hole on described lamp base core body 1 are provided with stay hooks 5.After power line is inserted in the line-entering hole, under fixed hook, walk around again, just can be firmly fixed at very much on the lamp base core body, even power line is torn, because the bending between online hole of power line and the fixed hook, the power that is added on the power line can not directly act on the thread tension disc, can not have influence on being connected of power line and thread tension disc, makes the connection of power line more solid and reliable.

Because tongue piece 9 and mouthful circle 10 are riveted on the lamp base core body 1 by riveting parts 7, riveting parts 7 be a copper rivet, and the end of the riveting parts 7 on described thread tension disc 3 and lamp base core body 1 is provided with to conduct electricity and is connected shell fragment 8, and shell fragment 8 is an elastic copper sheet, is circular-arc.Can pack into from the side of lamp base core body, cartridge clip is realized being electrically connected between thread tension disc and the electrode between thread tension disc and copper rivet.Simple in structure, be convenient to assembling.

The utility model adopts and be provided with cavity in the lamp base core body than prior art, is provided with clamp in cavity Sheet has the organization plan in the line hole that communicates with cavity at the lamp base core body, has fast wiring, easily, and power line connects Connect firmly, be difficult for getting loose, can not get an electric shock in the surface, safe and reliable advantage.
