Abstract
The utility model relates to a lamp holder with double central contactors, belonging to the technical field of lamp holders, and overcomes the problems of prior art, such as poor elasticity, loss of elasticity after long-term use, and incompatibility between conductivity of lamp holder and reliability of electrical contact. The lamp holder with double central contactors comprises a holder body, an opened cylinder arranged inside the holder body, an electrical contact terminal with a power line, and an elastic sheet arranged below the central contactors. The elastic sheet is easily processed by stamping molding, occupies less space, can be attached to the bottom of the double central contactors, and is easy to fix and assemble. The elastic sheet can retain the elasticity of the central contactor even the central contactor is made of copper sheet without elasticity, to ensure the good electrical contact between the central contactor and the lamp bulb.
Description
Technical field
The utility model belongs to technical field of lamp holders.
Background technology
Lamp socket is mainly used in fixedly bulb, makes bulb and power line realize being electrically connected simultaneously.Existing lamp socket includes pedestal, is arranged on the mouth tube in the pedestal, and the electric connecting terminal that links to each other with power line, one of electric connecting terminal and mouth tin are connected, and another links to each other with the center contact chip.The center contact chip all adopts copper sheet to make, this mainly is to utilize the copper sheet excellent conducting performance, but the elasticity of copper sheet is then relatively poor with respect to steel disc, repeatedly more changes the bulb, and the heat that produced of the long-term electrified light emitting of bulb, can make the center contact chip follow the string very soon.And the conductivity of steel disc is relatively poor compared with copper sheet, can not satisfy the reliable requirement of electrically contacting of electrical equipment.So keep lamp socket good electrical conductivity and electrical contact reliability just to exist contradiction.Some lamp socket is provided with spring below the contact chip of center, spring one end is withstood on the pedestal, the other end withstand on the center contact chip below, it is kept up upspring, the fixed structure complexity of spring like this, shared space is bigger, production assembly technology complexity causes cost to increase.
Summary of the invention
The purpose of this utility model is to provide a kind of can strengthen flexible pair of center of center contact chip contact chip lamp socket.
Be to realize the purpose of this utility model, described pair of center contact chip lamp socket comprises pedestal, is arranged on the mouth tube in the pedestal, is provided with shell fragment below the electric connecting terminal that links to each other with power line, center contact chip.Because the shell fragment punch forming is easy, it is few to take up space, can post below the contact chip of two centers, be convenient to fix, assembly technology is simple, even the center contact chip that copper sheet is made does not have elasticity, because the setting of shell fragment, make the center contact chip keep the elasticity of shell fragment equally, will good electrical contact be arranged with bulb.
Description of drawings
The drawing of accompanying drawing is described as follows:
Fig. 1 is the two centers of the utility model contact chip holder structure cutaway views,
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the topology view of center contact chip.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the two centers of the utility model contact chip lamp socket is described in further detail:
Described in the utility model pair of center contact chip lamp socket comprises pedestal (1), mouthful tube (2), electric connecting terminal (3), center contact chip (4), shell fragment (5), securing member (7).
Described shell fragment (5) is provided with fixing hole (6), and in center contact chip (4) was fixed on pedestal (1), mount was simple, easy, quick by securing member (7).Described shell fragment (5) is bent into same shape with center contact chip (4) and posts together, be convenient to same die stamping moulding, and shell fragment (5) and center contact chip (4) compact conformation, below shell fragment (5), still keep leaving certain space, be convenient to its strain activity.
Described pedestal (1) is established groove (8) in the bottom, the width of groove (8) is slightly larger than center contact chip (4) and shell fragment (5), described center contact chip (4) is installed in the interior groove (8) in pedestal (1) bottom with shell fragment (5), when securing member (7) adopts screw threads to fasten, center contact chip (4) and shell fragment (5) will be blocked by the side of groove (8), can be with not the screwing and rotate of screw, easy to assembly.
Claims (4)
1. two centers contact chip lamp socket comprises pedestal (1), is arranged on the mouth tube (2) in the pedestal (1), and the electric connecting terminal that links to each other with power line (3) is characterized in that being provided with shell fragment (5) below the center contact chip (4).
2. according to claim 1 pair of center contact chip lamp socket is characterized in that described shell fragment (5) is provided with fixing hole (6), by securing member (7) in center contact chip (4) is fixed on pedestal (1).
3. according to claim 1 and 2 pair of center contact chip lamp socket is characterized in that described shell fragment (5) and center contact chip (4) are bent into same shape and post together.
4. according to claim 1 and 2 pair of center contact chip lamp socket is characterized in that described center contact chip (4) and shell fragment (5) are installed in the interior groove (8) in pedestal (1) bottom.
