Abstract
The utility model relates to an electric contact resistant plastic weld-free lamp cap, comprising a metal thread fastener (1) and a plastic ring (2), wherein a wire (3) threads from a side hole (21) of the plastic ring (2), the bare portion of the wire (3) threads out from a middle hole (22) and clamped in the middle hole (22) by a rivet (4), and the middle hole is provided with a bottom seal cover (23). The electric contact resistant plastic weld-free lamp cap can prevent the bare portion of the lamp cap wire from contacting a circuit board, thereby protecting the circuit board from being damaged and effectively preventing the metal thread fastener from leakage.
Description
Technical field:
The utility model relates to the lamp holder technical field, exempts from the blowtorch head more specifically to a kind of lamp holder lead that prevents with the plastics that the lamp holder internal circuit board electrically contacts.
Background technology:
Electricity-saving lamp is made up of fluorescent tube, plastic, pcb board, lamp holder, and traditional energy-conservation lamp holder adopts metal to manufacture, and cooperate the back riveting on plastic with plastic, guarantees the bonding strength of lamp holder and plastic, accomplishes conducting of lamp holder and pcb board.The tradition lamp holder need be on lamp holder scolding tin, the tin cigarette that produces during scolding tin is harmful.So people have invented the glass lamp holder, the glass lamp holder is to fuse an insulating glass ring metal threaded buckling, and then is pressing the lead that can from the hole, pass to form the glass lamp holder at insulating glass ring upper sleeve metal cap.Glass lamp holder major defect is: metal threaded being buckled in when fusing with glass; Because glass dissolves temperature up to more than 2000 ℃; Plated nickel like this metal threaded be buckled in when fusing with glass ring can be because temperature be too high weakened; The metal threaded button surface of crossing simultaneously behind the high temperature very easily produces the ablation vestige, and deep blue is substandard products.
So people have invented plastics assembling lamp holder; As shown in Figure 1; Existing a kind of plastics assembling lamp holder; Its lamp holder is buckled 101 and is formed with plastic hoop 102 by metal threaded, and lead 103 penetrates from the side opening 1021 of plastic hoop 102, and the bare wire part 1031 of lead 103 passes and is fastened on the mesopore 1022 by rivet 104 from mesopore 1022.Its weak point is: 1, bare wire part 1031 is longer sometimes, and bare wire part 1031 might be buckled 101 and contacts and cause electric leakage with metal threaded.2, some has the electricity-saving lamp of specific (special) requirements in metal threaded button 101, wiring board 105 to be housed, and bare wire part 1031 can contact with wiring board 105, causes wiring board 105 short circuits and burns out.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And provide the anti-electrically plastics of contact to exempt from the blowtorch head; It can avoid the bare wire part of lamp holder lead to contact with wiring board, damages thereby cause wiring board, can effectively prevent metal threaded button electric leakage simultaneously.
The technological solution of the utility model is following:
The anti-electrically plastics of contact are exempted from the blowtorch head, comprise metal threaded button and plastic hoop, and lead penetrates from the side opening of plastic hoop, and the bare wire part of lead passes and is fastened on the mesopore by rivet from mesopore, and mesopore has the underseal lid.
Said wiring board is fixed on metal threaded smashing.
Said underseal lid is molded on the plastic hoop.
Form deep-slotted chip breaker on the said mesopore.
Form on the said plastic hoop and accommodate step, the cap portion of rivet is fastened on accommodates on the step.
The surface of said mesopore and side opening forms projection on same plane on this plane.
The beneficial effect of the utility model is:
It can avoid the bare wire part of lamp holder lead to contact with wiring board, damages thereby cause wiring board, can effectively prevent metal threaded button electric leakage simultaneously.
Description of drawings:
Fig. 1 is the prior art constructions sketch map
Fig. 2 is the structural representation of the utility model
Fig. 3 is the perspective exploded view of the utility model
Fig. 4 is the schematic perspective view of plastic hoop
Among Fig. 2 to 4: 1, metal threaded button; 2, plastic hoop; 3, lead; 31, bare wire part; 4, rivet; 5, wiring board; 21, side opening; 22, mesopore; 23, underseal lid; 24, accommodate step; 25, projection; 221, deep-slotted chip breaker.
Embodiment:
Embodiment: see shown in Fig. 2 to 4; The anti-electrically plastics of contact are exempted from the blowtorch head, comprise metal threaded button 1 and plastic hoop 2, and lead 3 penetrates from the side opening 21 of plastic hoop 2; The bare wire part 31 of lead 3 passes and is fastened on the mesopore 22 by rivet 4 from mesopore 22, and mesopore 22 has underseal lid 23.
Said wiring board 5 is fixed in the metal threaded button 1.
Said underseal lid 23 is molded on the plastic hoop 2.
Form deep-slotted chip breaker 221 on the said mesopore 22, make things convenient for bare wire part 31 to be fastened in the mesopore 22.
Form on the said plastic hoop 2 and accommodate step 24, the cap portion of rivet 4 is fastened on accommodates on the step 24, in order to avoid rock after rivet 4 riveted joints.
The surface of said mesopore 22 and side opening 21 forms projection 25 on same plane on this plane, projection 25 makes things convenient for that bare wire part 31 is housed in that projection 25 and mesopore 22 interplanars form recessedly goes out in the portion.
Operation principle: because the bare wire part 31 of lead 3 is no longer stretched out from mesopore 22; Do not cause electric leakage so can not contact with metal threaded button 1; Particularly some has the electricity-saving lamp of specific (special) requirements metal threaded smashing wiring board to be housed simultaneously, and the utility model bare wire part 31 can not contact with wiring board 5 and cause wiring board 5 damages.
