Utility model content

The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of lamp holder, it stably may be used Leaning on, be hardly damaged, contact is good.

The technical solution of the utility model is as follows:

A kind of lamp holder, including fore shell, fore shell one end is provided with the back cover removably connected, and the other end is provided with The end cap removably connected, is provided with the first union joint for being connected with light source in back cover, lamp holder also wraps Include compression spring, conducting strip and the binding post contacted with external power source；End cap runs through in the axial direction Having through hole, through-hole wall to be provided with the limited block for limiting described binding post, binding post hoop is provided with Spacing ring, binding post runs through through hole and one end ring is cased with compression spring, and one end of compression spring abuts Spacing ring, the other end abuts with the conducting strip being fixed on cover internal.

Further, lamp holder also includes the second union joint being connected with outside lamp socket, and second connects headgear Outside end cap.

Further, the second union joint outer surface is provided with the screw thread being connected with outside lamp socket.

Further, lamp holder also includes that pcb board, fore shell and back cover form a receiving chamber, pcb board position In accommodating intracavity and fixing with the end face of back cover being connected.

Further, pcb board is provided with WIFI module and USB interface, and described front shell side wall is provided with Accommodate the opening of USB interface.

Lamp holder also includes the plug for covering USB interface.

Further, the first union joint is tubular structure, is internally provided with screw thread, and the first union joint leans on One end of nearly back cover is fixed with the shell fragment with light source contacts.

Summary technical scheme, the beneficial effects of the utility model: when one end and the external modulation of lamp holder When seat connects, binding post is under the effect of compression spring, and lamp holder crosses pine with outside lamp socket or tension can Enough well contact with external power source；When the other end of lamp holder is connected with light source, lamp holder and light source mistake Pine or during tension, shell fragment well and light source contacts can arrive good conductive effect.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand this reality By novel technological means, and can be practiced according to the content of description, and in order to allow this practicality Novel above and other objects, features and advantages can become apparent, below especially exemplified by preferably implementing Example, and coordinate accompanying drawing, describe in detail as follows.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Fig. 2 is this utility model sectional view.

Detailed description of the invention

It should be noted that in the case of not conflicting, in embodiment in the application and embodiment Feature can be mutually combined.Below in conjunction with the accompanying drawings this utility model is described further.

As depicted in figs. 1 and 2, a kind of lamp holder, including fore shell 10, fore shell 10 one end is provided with removable Unloading the back cover 20 of connection, the other end is provided with the end cap 30 removably connected, be provided with in back cover 20 for The first union joint 201 being connected with light source (not shown)；Lamp holder also includes compression spring 301, Conducting strip 302 and the binding post 303 contacted with external power source；End cap 30 also extends through in the axial direction Through hole 304, through hole 304 inwall is had to be provided with the limited block 306 for limiting described binding post 303, Binding post 303 hoop is provided with spacing ring 305, and binding post 303 runs through through hole 304 and one end ring is cased with Compression spring 301, one end of compression spring 301 abuts spacing ring 305, the other end be fixed on end cap Conducting strip 302 within 30 abuts.

Specifically, lamp holder also includes the second union joint 306 being connected with outside lamp socket (not shown), Second union joint 306 is placed on outside end cap 30.Second union joint 306 outer surface is provided with and outside lamp socket (figure Not shown in) screw thread that connects.Lamp holder also includes that pcb board 202, fore shell 10 are formed with back cover 20 One accommodates chamber, and pcb board 202 is positioned at and accommodates intracavity and fixing with the end face of back cover 20 be connected.PCB Plate 202 is provided with WIFI module (not shown) and USB interface 204, and fore shell 10 sidewall sets There is the opening 101 accommodating USB interface.Lamp holder also includes the plug 102 for covering opening 101.
