Bayonet type socket

Abstract

The invention discloses a bayonet lamp cap which comprises a lamp cap body (1) made from insulating material and two conductive contacts (2) arranged at the top of the lamp cap body (1), wherein, the lamp cap body (1) is provided with a couple of bayonet pins (11); the section of the conductive contacts (2) is of reversed U shape; the top of the lamp cap body (1) is provided with two grooves (12) which can be embedded with corresponding conductive contacts (2); the inside of each groove (12) is provided with a lug boss (13) which is matched with the inner lateral wall (21) of the conductive contact (2); and each lug boss (13) is provided with a through hole (14) along the axial direction of the lamp cap body (1). Compared with the prior art, the basic frame structure of the lamp cap body of the bayonet lamp cap is not changed; the whole lamp cap body can be made from plastics, thereby reducing the production cost greatly and being convenient for manufacturing; at the same time, the electric connection assembly can be finished just by plugging the conductive contacts at the top of the lamp cap body; the assembly working procedure is very simple; and the invention can ensure good electric connection between a line conductor and the conductive contacts.

Description

technical field [0001] The invention relates to the technical field of illuminating lamps, in particular to a bayonet type lamp cap. Background technique [0002] The traditional bayonet type lamp cap includes a lamp cap housing with a bayonet pin, an insulator arranged on the top of the lamp cap housing and two conductive contacts embedded in the insulator, wherein the lamp cap housing is made of metal, and the insulator is made of For materials such as glass and ceramics, the two conductive contacts are exposed outside the insulator. During actual processing, the bottom of each conductive contact is electrically connected to the wire drawn out from the circuit board by welding. Just disclose similar a kind of lamp holder in Chinese invention patent " a kind of bayonet type lamp holder " that the patent No. is ZL00239498.7 (notification number is CN2465356Y). In the bayonet type lamp cap, lead wires and contacts are embedded in the lamp cap body made of plastic material, a...

AI Technical Summary

Problems solved by technology

This kind of electric connection structure through welding has cumbersome assembly process and is not reliable enough. It is easy to loosen and cause poor contact, which makes the lighting lamp unable to work. Moreover, the lamp head body is made of plastic material, which is costly and needs to be embedded. The two wires inside cannot be in contact, which will increase the difficulty of manufacture. Therefore, the existing bayonet type lamp holder needs to be further improved
