Abstract
The utility model relates to a screw ceramic lamp holder, which overcomes the defects that metal components of the lamp holder in the prior art are easy to loosen to cause the pressure resistance of the lamp holder to become poor and the safety performance of an electric lamp is influenced. The utility model comprises an opening cylinder and an electrode terminal; a groove which can be used for holding a center contact piece is arranged in a concave cavity of a porcelain casing; two fixed folding pieces of the opening cylinder are fixed in fixing holes on both sides of the center contact piece of the bottom of the concave cavity of a porcelain casing; an annular convex edge is arranged on the peripherical edge of the groove; both sides of the center contact piece next to the fixed folding pieces are in a trimming shape. The utility model has the advantages of simple structure, less parts, larger creepage distance between connecting parts and electrodes, high voltage resistance, good fixity, high durability and cost reduction of production manufacture.
Description
The utility model relates to the screw type porcelain lamp socket that a kind of withstand voltage high high-pressure mercury-vapor lamp or high-pressure sodium lamp are used.
At existing high-pressure mercury fluorescent tube or the bulb of being used for, the lamp socket of high-pressure sodium fluorescent tube or bulb, because the requirement of withstand voltage of the lamp of being installed often requires lamp socket that very high withstand voltage properties is arranged, withstand voltage up to more than 8500 volts, these lamp sockets generally are used to be installed in street lamp.Produce vibration because automobile makes to cross at road, cause getting loose of each metal parts in the lamp socket, cause the withstand voltage properties variation of lamp socket, wherein the metal parts slight distance that is shifted just may produce the arc electricity between electrode, influences the security performance of electric light.
The purpose of this utility model is to overcome the deficiency in the above-mentioned prior art, provides a kind of electric light safe screw type porcelain lamp socket.
For realizing the purpose of this utility model, described screw type porcelain lamp socket, comprise the porcelain shell, be contained in the mouth tube in the porcelain shell cavity, be arranged on the electrode terminal on the porcelain shell, be provided with the groove that holds the center contact chip in the porcelain shell cavity, mouthful the tube two fixedly tabs be fixed in the fixing hole of porcelain shell cavity bottom centre contact chip both sides, described groove circumferential edges is provided with annular rim, and center contact chip dual-side is the side cut shape by fixing tabs place.
The drawing of accompanying drawing is described as follows:

Below in conjunction with accompanying drawing, the embodiment of the utility model screw type porcelain lamp socket is described in further detail:
As shown in fig. 1, the described screw type porcelain of utility model lamp socket comprises that the porcelain shell 1. of firing shaping is contained in the mouth tube 2 in porcelain shell 1 cavity.Mouthful tube 2 is made of metal, and barrel has and cooperates the screw thread that is spirally connected with lamp holder.Be provided with the circular groove 5 that holds center contact chip 4 in porcelain shell 1 cavity, porcelain shell 1 is provided with the electrode terminal 3 that is connected with electric wire, and electrode terminal 3 is electrically connected with mouth tube 2 and center contact chip 4 respectively on porcelain shell 1.Mouthful tube 2 two fixedly tabs 6 is fixed in the fixing hole of porcelain shell 1 cavity bottom centre contact chip 4 both sides, and through port tube screw 11 is fixed in the cavity of porcelain shell 1 with one of them electrode terminal 3.The electric shock position of former center contact chip is the disk shape, as shown in Figure 5.The utility model center contact chip 4 dual-sides are 14 shapes of cutting edge by fixing tabs 6 places, as shown in Figure 4, are fixed on the porcelain shell 1 by center contact chip screw 12 and nut 13 and another electrode terminal 3 wherein.Circular groove 5 by the edge at fixing tabs 6 places from fixedly tabs 6 is nearest, when center contact chip 4 is fixed in the circular groove 5, if the electric shock position of center contact chip 4 is the disk shape, then it produces the arc electricity easily by the fixing edge at tabs 6 places because of creepage distance is little, influences withstand voltage.When center contact chip 4 dual-sides when fixedly tabs 6 places are the side cut shape, the electric shock position of center contact chip 4 increases by the fixing Edge Distance at tabs 6 places, thereby has increased creepage distance, has improved withstand voltage.No ring-type chimb on original groove circumferential edges, as shown in Figure 7.The utility model groove 5 circumferential edges are provided with annular rim 7, as shown in Figure 2.This has further increased the electric shock position of center contact chip 4 and the fixing creepage distance between the tabs 6, has improved withstand voltage.Described mouthful of tube 2 sidewalls are provided with two pairs of slotted holes 8, the sidewall inwardly protruding of part between two contiguous slotted holes 8.After in the lamp holder loading port tube 2, because suppressing of mouthful tube 2 sidewall inwardly protruding portions makes lamp holder be securely fixed in more in mouthful tube.Original mouth tube does not have these characteristics, as shown in Figure 8.Be provided with hexagonal compacting nut 9 in described porcelain shell 1 screw fixed hole, as shown in Figure 3, hexagonal compacting nut 9 is provided with salient point 10 by the punch forming of steel disc sheet in its six sides, and the tabs of side top constitutes center hole, and has a screw thread.The hexagonal compacting nut of this structure directly is contained on the porcelain shell, it has high robustness, and simple in structure, and production cost is low, be embedded in the nut fixing hole of porcelain shell, the elastic force of invar sheet and being stuck in the hole not only avoids original nut need be riveted on the porcelain shell, as shown in Figure 6, the defective of riveted joint difficulty, and because of it does not need riveting at nut fixing hole two ends, compared with original riveting nut further increased and electrode between creepage distance, resistance to pressure is further enhanced.
The utility model is than prior art, owing to adopt the groove circumferential edges to be provided with annular rim, center contact sheet bulb two Side is side cut shape structure by fixing tabs place, thereby so that the creep age distance between center contact sheet bulb and mouthful tube increased Add, improved withstand voltage properties. Described mouthful of tube sidewall is provided with two pairs of slotted holes, the sidewall inwardly protruding of part between the slotted hole, Lamp holder is fixed in mouthful tube more firmly, forms good electrically contacting. In described porcelain shell screw fixed hole, be provided with six Angle compacting nut, assembly structure is simple, increased and electrode between creep age distance. After passing it with screw, because of it Elasticity is not so that screw can get loose.
