Abstract
The utility model relates to a lamp base core of a safe structure of an improved ring of ports and overcomes the danger of electric shock caused by the charged surface of the tube of ports of the current technology. The lamp base core of the safe structure of the improved ring of ports comprises a tube of ports, a body, a terminal post and a central contact piece, wherein, the body is provided with a side contact piece which is separated from the tube of ports and connected with the terminal column of the body. The tube of ports is provided with a notch which is arranged beside the side contact piece. The body 3 is provided with a switch 10 which is connected in series between the central contact piece 6 and the terminal column 7. The utility model has the advantages of few structural changes, a simple structure and low production manufacturing cost.
Description
The utility model relates to a kind of mouthful lamp base core of circle safeguard construction of improveing.
Existing lamp base core mainly is to be used for affixed bulb, makes the lamp holder of bulb fix and be connected wherein.It comprises a fixedly mouth tube of lamp holder, one link to each other with the lamp holder electrode of bulb the center contact chip, a body mouthful tin is fixed on the body.Body is provided with two binding posts, and mouthful tube central authorities are provided with central contact chip, and a mouthful tube links to each other with one of them binding post, and a mouthful tube links to each other with another binding post.The mouth tube is made for metal, can conduct electricity a suitable electrode.When screw-socket bulb is being put into the process of lamp socket, a mouthful tube can be at first touched at the lamp holder position of bulb, because a mouthful tube directly links to each other with binding post, when on the binding post voltage being arranged, voltage directly reaches on the lamp holder, this has been equivalent to increase unintentionally the length of mouthful tube, and in a single day user's hand touches the lamp holder position, causes the danger of electric shock easily.
The purpose of this utility model is to provide the lamp base core of a kind of mouthful of uncharged improvement of tube mouthful circle safeguard construction.
For realizing the purpose of this utility model, the lamp base core of described improvement mouth circle safeguard construction includes a mouthful tube, and body, binding post, center contact chip, described body are provided with other contact, and described other contact keeps isolating with the mouth tube and links to each other with the binding post of body.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the installation diagram of the lamp base core of the utility model improvement mouthful circle safeguard construction.
Fig. 2 is the lamp base core cut-away view of the utility model improvement mouthful circle safeguard construction.
Fig. 3 is the body interior circuit diagram.
Below in conjunction with accompanying drawing, the utility model is improved mouthful embodiment of the lamp base core of circle safeguard construction is described in further detail:
As shown in Fig. 1,2, the lamp base core of improvement described in the utility model mouthful circle safeguard construction comprises a mouthful tube 1, other contact 2, body 3, center contact chip 6, binding post 4,7.Described mouthful tube 1 perisporium is provided with the lamp holder of bulb wants the screw thread that adapts to, and body 3 is made for plastics, is the garden column, and mouthful tin 1 is fixed on the body 3.The next door is provided with other contact 2 on mouth tube 1, and described other contact 2 is riveted on the binding post 4 by rivet 9.Be provided with switch 10 in body 3, this switch 10 is serially connected between center contact chip 6 and the binding post 7, and as shown in Figure 3, the structure of switch 10 can be button, and is plug-type, and perhaps stay-supported is convenient to electrode is carried out voltage control.Described mouthful of tube 1 is provided with notch 11, and this notch 11 is in other contact 2 sides.Because mouthful tube 1 does not directly link to each other with binding post 4, when being connected to power line 5,8 on the binding post 4,7, have only other contact 2 and center contact chip 6 to have voltage, and mouthful tube itself and no-voltage, have only when the lamp holder of bulb is presented to mouth tube 1 bottom of lamp socket, lamp holder side touches other contact 2, at this moment, lamp holder has nearly all dropped in mouthful tube, the metallic conduction part of lamp holder outside is wrapped in wherein by a mouthful tube 1, avoided the lamp holder can be charged, caused the danger of electric shock once touching mouthful tube 1, can be safer to the user.
The utility model is than prior art, owing to be provided with other contact at body, described other contact keeps with a mouthful tube The isolation and link to each other with the binding post of body. It is not charged to have mouthful tube, and structural change is few, and is simple in structure, manufacturing cost Low advantage.
