Abstract
The utility model belongs to the technical field of lamp holder, solving the problem that the existing lamp holder mouth is looped on the end mouth of the side wall of the concave cavity of the porcelain holder, which is correspondingly and comparatively exposed and which is easy to be touched by hands to cause electric shock. The lamp holder of the utility model comprises a porcelain holder; a concave cavity used for containing a lamp cap is arranged in the porcelain holder; the inner wall of the concave cavity is provided with screw threads, and the bottom of the concave cavity is provided with a central contact chip which is connected with an electric connection end; mouth-ring screws are arranged on the screw threads of the concave cavity; the bottom of the concave cavity is provided with a side contact chip which is connected with the other electric connection end; the mouth-ring and the side contact chip are separated; the inner wall of the concave cavity is provided with grooves; the mouth-ring is provided with convex parts which are concave in the grooves. Because the mouth-ring and the side contact chip are separated in the concave cavity, in the normal state, the mouth-ring has no electricity, and though the fingers contact the mouth-ring, the phenomenon of electric shock cannot occur. When a lamp bulb is arranged in the lamp holder, the electrode of the lamp cap is contacted with the side contact chip, and the lamp bulb is lighted up; as the tail part of the lamp bulb is contained in the containing cavity, the finger cannot contact the mouth-ring, and the use is safer.
Description
Technical field
The utility model belongs to technical field of lamp holders, and being one has the porcelain seat, electric connecting terminal, center contact, the lamp socket of mouthful circle.
Background technology
Existing lamp socket includes the porcelain seat, is provided with the cavity of ccontaining lamp holder in the porcelain seat, the electric connecting terminal that the porcelain seat is provided with two electric connecting terminals that are connected with the center contact and is connected with the mouth circle, and a mouthful circle is arranged in the cavity of porcelain seat.When electric connecting terminal is switched on, a center contact and a mouthful astragal electricity, because the center contact is arranged on the bottom of porcelain seat cavity, and mouthful circle is arranged on the wall port of cavity of porcelain seat, relatively exposes comparatively speaking, is touched by hand easily and produces Danger Electric shock risk.
Summary of the invention
The purpose of this utility model is to provide a kind of lamp socket of difficult generation electric shock.
For realizing the purpose of this utility model, described lamp socket comprises the porcelain seat, in the porcelain seat, be provided with the cavity of ccontaining lamp holder, the cavity internal face is provided with screw thread, and the bottom of cavity is provided with the center contact that is connected with electric connecting terminal, and a mouthful circle spiral is arranged on the screw thread of cavity, be provided with the side contact that is connected with another electric connecting terminal in the bottom of cavity, mouth circle and side contact keep isolating, and the cavity internal face is provided with groove, and mouth encloses the lug boss that is provided with in the recessed groove.
Owing to be provided with the side contact in the bottom of cavity, mouthful circle and side contact keep isolating, and make that mouthful circle is not charged under normal conditions, at this moment, also can not get an electric shock even finger touches a mouthful circle.Mouthful circle is by rotation, screw thread on it combine with screw thread on the cavity internal face insert in the cavity, produces a lug boss again on the mouth circle, allows make in the recessed groove of lug boss mouthful to enclose fix and can't rotate.
Description of drawings
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structure chart of the utility model lamp socket.
Fig. 2 is the vertical view among Fig. 1.
Fig. 3 is the upward view among Fig. 1.
Fig. 4 is for removing mouthful view of circle among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model lamp socket is described in further detail.
As shown in Fig. 3,4, lamp socket described in the utility model comprises porcelain seat 1, cavity 2, screw thread 3, center contact 4, side contact 5, electric connecting terminal 6, groove 7, mouthful circle 8, lug boss 9, containing cavity 10, connecting hole 11, screw 12, flange 13, fixing hole 14.
Porcelain seat 1 is cylindric, and its central authorities are provided with a cavity 2, is provided with screw thread 3 on cavity 2 internal faces, can screw in for mouthful circle 8.Two connecting holes 11 and two fixing holes 14 are arranged on the porcelain seat 1.Fixing hole 14 makes things convenient for connector that porcelain seat 1 and other objects are fixed together.Mouthful circle has on 8 and the corresponding screw thread of cavity 2 internal face screw threads 3.Cavity 2 bottoms of porcelain seat 1 are provided with two connecting holes 11, and one of them electric connecting terminal 6 is connected in connecting hole 11 by screw 12 with center contact 4.Mouthful circle 8 is arranged on the screw thread 3 of sidewall of cavity 2 by spiral, cavity 2 internal faces are provided with four grooves 7, mouth circle 8 is provided with four lug bosses 9 in the recessed groove 7, described mouthful of circle 8 end faces are provided with flange 13, described lug boss 9 is arranged on the flange 13, is snapped in by the cross section notch of groove 7.In the bottom of cavity 2, another electric connecting terminal 6 is connected in connecting hole 11 by screw 12 with side contact 5, and mouthful circle 8 and side contact 5 keep isolating.On described cavity 2 ports containing cavity 10 is arranged, flange 13 is arranged on containing cavity 10 bottoms.
During use, after electric connecting terminal was connected with the mains, center contact and side contact were charged, and need aim at cavity with the lamp holder of bulb this moment when bulb is installed, and during fitting operation, finger contacts a mouthful circle easily, but because mouthful circle is not charged, so can not produce the electric shock phenomenon.Behind the lamp holder screw-in mouthful circle with bulb, the bottom electrode of lamp holder will extend through a mouthful circle, contact with the side contact, and bulb is switched on and lighted.Because in screwing in the process of bulb, finger is often from broken ring, so this structure is difficult for getting an electric shock.Owing on the cavity port, containing cavity is arranged, the afterbody of bulb partly is contained in wherein, thereby has sheltered from flange at the mouth circle of containing cavity bottom, make the finger can't the contact opening circle, use safer.
