Abstract

The utility model discloses a double purpose lamp socket for a screw and bayonet lamp capable of being matched with a screw or socket bulb. The utility model is characterized in that the parts of a screw and socket lamp holder form a lamp holder, and a bit long contact used for the screw bulb is arranged between two contacts of a common socket lamp holder. A socket guide groove used for the in-and-out of a hook of the socket bulb is pressed on a thread groove of a common screw lamp holder. The back end of the thread groove is provided with four location cambered surfaces. The four location cambered surfaces take the actions of screwing-in and displacement limiting for the screw bulb, being able to make the socket lamp holder freely pass in and out. The utility model has the advantages of reasonable design, simple structure, convenient operation, safety and reliability.

Description

Double purpose lamp socket for screw and baymet lamp

The utility model relates to a kind of lamp holder, the dual-purpose lamp holder of particularly a kind of screw socket bayonet socket.

Lamp holder of the prior art mainly is single screw cap and single socket lamp holder, and a kind of lamp holder can only adapt to a kind of corresponding bulb, makes troubles for daily use.

In order to address this problem, common way is the structure that changes the normal lamp holder electrode contact.Chinese patent application GG88212268 proposes: change the location status between the common bayonet cap two return electrode contacts, between two return electrodes an insulated column is set, adopt special-purpose contact members, make it to adapt to bayonet socket, two kinds of bulbs of screw socket.But, because special-purpose contact members complex structure, the service position less stable, intermediate insulation post mechanical strength is easily impaired, these constituted this lamp holder structurally with the shortcoming of using.

The purpose of this utility model is to provide a kind of screw socket socket dual-purpose lamp holder, and it can effectively and safely adapt to two kinds of bulbs of screw socket socket.

The purpose of this utility model is achieved in that an a little longer middle contact is set between two electrode contacts of conventional jack lamp holder, as screw socket live wire contact.Utilize thread groove and this three contacts mates location of common screw cap, be suppressed with the socket guide groove on the thread groove, the thread groove rear end is symmetrical arranged four location cambered surfaces, wherein have the slotted eye that is connected with the socket guide groove on two relative location cambered surfaces, form socket cambered surface hook, like this, both can guarantee socket bulb location on socket cambered surface hook, simultaneously, also can guarantee the screw-in depth of screw-socket bulb in thread groove, play the effect of safety location.The utility model is made of contact assembly (15), screw socket socket assembly (16), connecting terminal components (17) and bakelite insulation assembly (18).Contact assembly (15) comprising: screw socket live wire contact (3), socket live wire contact (4) and socket zero line contact (5).Screw socket socket assembly (16) comprising: thread groove (2), socket guide groove (1), location cambered surface (8) and socket cambered surface hook (9).Connecting terminal components (17) comprising: live wire compressing tablet (6), zero line compressing tablet (7), fire line terminal (11), zero terminal (12), zero line compressing tablet location hole (13) and live wire compressing tablet location hole (14).Bakelite insulation assembly (18) comprising: insulating spacer (10), bakelite core print seat (21), bakelite shell (19) and bakelite skull (20).Socket live wire contact (4) and socket zero line contact (5) are the standard contact members of conventional jack bulb.Be screw socket live wire contact (3) between these two contacts, its length is longer than this two standard contact members slightly.Screw socket live wire contact (3) and the shared live wire compressing tablet of socket live wire contact (4) (6), live wire compressing tablet (6) is by live wire compressing tablet location hole (13) location, and zero line compressing tablet (7) is located by zero line compressing tablet hole (14).Be equiped with an insulating spacer (10) that connects together with bakelite core print seat (21) between live wire compressing tablet (6) and the zero line compressing tablet (7).Be connected with fire line terminal (11) on the live wire compressing tablet (6), be connected with zero terminal (12) on the zero line compressing tablet (7).The axis of three contacts is in same plane.Screw socket socket assembly (16) is fixed on the bakelite core print seat (21) by two dog screws (22), wherein a dog screw (22) is fastened on the bakelite core print seat (21) with zero line compressing tablet (7), makes zero terminal (12), zero line compressing tablet (7) and screw socket socket assembly (16) constitute the zero line path.On the thread groove (2) of both sides, three contact axis planes, be suppressed with socket guide groove (1).Thread groove (2) rear end symmetry is suppressed with four location cambered surfaces (8), just in time contains the metal head end of socket lamp holder.Wherein dig grooved hole respectively on two location cambered surfaces (8), and link to each other respectively, form two notch cambered surface hooks (9) with socket guide groove (1).

The utility model has been because utilized the standard contact members of conventional jack lamp holder and the thread groove of general screw cap, and can adapt to the accessory requirement of screw socket, two kinds of bulbs of socket.So have advantage reasonable in design, simple in structure, easy to use; Because screw socket live wire contact also adopts the version of similar socket live wire contact, live wire contact and zero line contact can not bump and connect the formation short circuit risk, so its structure meets the electrical safety requirement simultaneously; In addition because location cambered surface and socket cambered surface hook are adopted in the thread groove rear end, so two kinds of bulbs of screw socket and socket can be put into or draw off in safe and free ground.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the longitudinal sectional view according to the dual-purpose lamp holder of screw socket socket that the utility model proposes.

Fig. 2 is the A-A cutaway view of the dual-purpose lamp holder of screw socket socket.

Fig. 3 is the B-B cutaway view of the dual-purpose lamp holder of screw socket socket.

Describe details and operating position in detail below in conjunction with Fig. 1, Fig. 2 and Fig. 3 according to the concrete lamp holder that the utility model proposes.

Fire line terminal (11) links to each other with power firestreak, and zero terminal (12) joins with zero-power line.Screw-socket bulb screws in through thread groove (2), and when its screw thread front end entered the lower edge of four location cambered surfaces (8), bulb top metal round spot just in time contacted with screw socket live wire contact (3).At this moment, because socket live wire contact (4) and socket zero line contact (5) all are shorter than screw socket live wire contact (3), so can never contact with these two short contacts by the metallic conduction position of the screw-socket bulb of four location cambered surface (8) position-limiting actions.Simultaneously, bulb screw thread and thread groove (2) and zero terminal are formed the zero line path.So far, screw-socket bulb safety is positioned in the dual-purpose lamp holder of screw socket socket.Two hooks of socket bulb are inserted along socket guide groove (1), and its metal front end Cylinder enters the tubular space that four location cambered surfaces (8) constitute, and two hooks on the bulb are hung on two socket cambered surface hooks (9).Because between two metal contact in socket bulb top is insulator, it can withstand upwards compression of screw socket live wire contact (3), and at this moment, two hard contacts of bulb touch socket live wire contact (4) and socket zero line contact (5) respectively.So far, socket bulb safety is positioned in the dual-purpose lamp holder of screw socket socket.
