Abstract

The utility model relates to a bayonet lamp cap which comprises a lamp cap body (1) made of insulating material and two conductive contacts (2) arranged at the top part of the lamp cap body (1), wherein, a pair of bayonet pins (11) are arranged on the lamp cap body (1); the section of the conductive contacts (2) is U-shaped; two grooves (12) capable of accommodating corresponding conductive contacts (2) are formed at the top part of the lamp cap body (1); and a lug boss (13) matched with the inner side wall (21) of each conductive contact (2) is formed in each groove (12), and a through hole (14) in the axial direction of the lamp cap body (1) is formed on each lug boss (13). Compared with the prior art, the utility model has the advantages that the basic frame structure of the lamp cap body is unchanged and the lamp cap body can adopt plastic to manufacture, so as to greatly reduce manufacture cost and facilitate manufacture; and at the same time, the electrical connection assembly can be completed only when the conductive contacts are inserted in the top part of the lamp cap body in a matching manner, so that the assembly procedure is easy, and the favorable contact between conducting wire and the conductive contacts is guaranteed.

Description

A kind of bayonet cap

Technical field

The utility model relates to the technical field of illuminating lamp, especially refers to a kind of bayonet cap.

Background technology

Traditional bayonet cap, comprise the shell of lamp base that has bayonet pin, be arranged on the insulator at shell of lamp base top and be embedded two conductive contacts in insulator, wherein, shell of lamp base adopts the metal manufacturing, insulator adopts materials such as glass, pottery, two conductive contacts expose to outside the insulator, add man-hour actual, and the bottom of each conductive contact all is electrically connected by the lead of drawing on welding and the wiring board.As the patent No. is that the Chinese utility model patent " a kind of bayonet cap " of ZL00239498.7 (notification number is CN2465356Y) discloses similar a kind of lamp holder.This bayonet cap is to be embedded lead and contact in the lamp holder body of plastic material, again lead is welded mutually and is electrically connected with copper tree lace in the fluorescent tube.This electric connection structure by welding, assembly process is loaded down with trivial details, and firm inadequately, and is loosening easily and come in contact bad, cause illuminating lamp to work, and the lamp holder body adopts the injection moulding of plastic material entity, and cost is higher, and need to guarantee that two leads that are embedded in it can not contact, can increase manufacture difficulty, therefore, existing bayonet cap needs further improvement.

Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of be easy to make and can significantly reduce production costs, assembly process is simple more and can guarantee to electrically contact good bayonet cap.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this bayonet cap, include lamp holder body made of insulating material and two conductive contacts that are arranged on the lamp holder bodies top, wherein, described lamp holder body is provided with a pair of bayonet pin, it is characterized in that: the cross section of described conductive contact is inverted U, the top of described lamp holder body is provided with two grooves that can be embedded corresponding conductive contact, be provided with a boss that adapts with the madial wall of conductive contact in each groove, and, each boss along described lamp holder body shaft to have a through hole.

Described lamp holder body can adopt various insulating material manufacturings, and the plastics one is injection molded such as adopting; And conductive contact can adopt the manufacturing of metal material entity, also can adopt the injection moulding of plastics one after, electrodeposited coating in the re-plating.

Because lead has certain line footpath, when making conductive contact be set in the boss outside, have the gap that holds lead between conductive contact and the boss, can be provided with a chase in the position that joins with described through hole oral area on the described boss top surface;

Equally, for increasing the gap that can hold lead between conductive contact and the boss, can on the described boss of correspondence, respectively offer a tank in the position of chase end on the madial wall of described conductive contact.

Compared with prior art, advantage of the present utility model is: by conductive contact being designed to the cross section is inverted U, and the boss of cooperation lamp holder bodies top, make conductive contact can be set in the boss outside, and because the peripheral shape of this boss adapts with the madial wall of height with conductive contact, after making conductive contact be inserted on the lamp holder bodies top in the corresponding grooves, conductive contact just in time wraps boss, and the top of boss can be pressed close to mutually with the madial wall of conductive contact, like this, when illuminating lamp product practical set, the lead of drawing on the wiring board just passes from the through hole of boss, and the end of lead just can come in contact with the madial wall of conductive contact and lead and conductive contact are electrically connected; Bayonet cap of the present utility model, the basic frame structure of lamp holder body is constant, and lamp holder body entire body can adopt the plastics manufacturing, can significantly reduce production costs, and be convenient to make, simultaneously, as long as the conductive contact inserting on the lamp holder bodies top, can be finished being electrically connected assembling, saved processing steps such as scolding tin, assembly process is very simple, and can guarantee to electrically contact between lead and the conductive contact good.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 4, this bayonet cap includes lamp holder body 1 made of insulating material and is embedded two conductive contacts 2 in lamp holder bodies top 1;

Wherein, the cross section of described conductive contact 2 is inverted U, also is that conductive contact 2 inside have cavity;

Described lamp holder body 1 outside is provided with a pair of bayonet pin 11, the top of lamp holder body 1 is provided with two grooves 12 that can be embedded corresponding conductive contact 2, be provided with a boss 13 that adapts with the madial wall 21 of conductive contact 2 in each groove 12, and, the described lamp holder body in each boss 13 upper edge 1 is axial has a through hole 14, this through hole 14 passes boss 13 tops, and lamp holder body 1 inside is connected with the outside at lamp holder body 1 top;

Simultaneously, be provided with a chase 15 in the position that joins with described through hole 14 oral areas on described boss 13 top surfaces, and on the madial wall 21 of described conductive contact 2 on the described boss 13 of correspondence the position of 15 two ends of chase respectively offer a tank 22.

When practical application, two leads 3 that wiring board 4 from illuminating lamp is drawn pass corresponding through hole 14, and make lead 3 ends be positioned at the chase 15 on boss 13 surfaces, like this, after conductive contact 2 is inserted on lamp holder body 1 top in the corresponding grooves 12, the top of conductive contact 2 roughly flushes with lamp holder body 1 top, and the madial wall 21 of conductive contact 2 just comes in contact with lead 3 ends, thereby lead 3 and conductive contact 2 are electrically connected.
