Abstract

The utility model relates to a lamp holder which is suitable for a PL lamp and comprises a lamp holder body and a conductive terminal which is fixedly arranged in the lamp holder body. The lamp holder is characterized in that the conductor terminal is composed of an L-shaped contact piece, a terminal panel which is integrally shaped with the L-shaped contact piece and is arranged on the other side of the L-shaped contact piece and two pieces of eight-shape included angle contact pieces which are respectively extended inwards from the edge of a gap which is opened on the central position of the terminal panel, a disconnection preventing device which prevents a supply wire from disconnecting after the supply wire is inserted is arranged on the top plate of the L-shaped contact piece, which is vertical to the terminal panel. The lamp holder of the utility model is characterized in that the holder is easily inserted, contact is sensitive, and the holder is durable.

Description

A kind of novel PL lamp holder

Technical field

The utility model belongs to the socket field of light fixture, especially relates to a kind of lamp holder of the PL of being applicable to lamp.

Background technology

Mainly form at the lamp holder (shown in Fig. 6,7) that occurs on the market now by cap body, conducting terminal, extend outward two backs that bend inwards for being shaped as of conducting terminal mitre joint contact from terminal panel both sides and form two jiaos of relative connection delta contacts, because the connection delta contact stretches out back and bends inwards, easy offset direction when causing PL lamp holder haptic element to insert inner conducting terminal, and positive and negative short circuit bumps out spark after can causing wrong plug; Also, cause the toughness of contact chip and terminal panel intersection bad, distortion occurs, two connection delta contacts promptly occur and separate phenomenon, finally cause the conducting terminal contact insensitive to both sides because plug is constantly backed down for a long time.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of easy insertion, contact sensitivity and durable PL lamp holder are provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel PL lamp holder, comprise cap body, and be fixed on the conducting terminal that is provided with in the cap body, it is characterized in that described conducting terminal is by L shaped contact chip, and it is one-body molded and be arranged on the terminal panel of L shaped contact chip another side with L shaped contact chip, two splayed mitre joint contacts that also have the edge of offering indentation, there from terminal panel center to extend internally out respectively, the perpendicular top board of described L shaped contact chip and terminal panel is provided with and will prevents the anti-drop device that electric wire comes off after the electric wire insertion.

Described anti-drop device is included in and offers on the top board and little big corresponding inclination strip shape gob of electric wire and the spur that is provided with on the end of inclination strip shape gob lower plywood, and described spur has realized penetrating electric wire and block the anticreep effect of electric wire when transfering to from the inclination strip shape gob.

The beneficial effects of the utility model are: owing to offer two splayed mitre joint contacts that the edge of indentation, there extends internally out respectively from terminal panel center, so when PL lamp holder haptic element inserts, haptic element backs down splayed mitre joint contact, so the scope that haptic element inserts is bigger and contact gear ratio is sensitive; Again because when PL lamp holder haptic element backs down splayed mitre joint contact, the stress point that power is backed down in support no longer is the edge that contact chip and terminal panel cross, but be distributed on two splayed mitre joint contacts, and the good toughness of mitre joint contact, thus for the lamp holder that has used this terminal service life prolonged; Prevent the anti-drop device that electric wire comes off because the perpendicular top board of L shaped contact chip and terminal panel is provided with after will electric wire inserting again, and prevent that electric wire from not changing places with producing effect and come off out when dismantling; Also owing to aspect the manufacturing, saved a lot of materials.

The specific embodiment

Shown in Fig. 1 to 5, the utility model comprises cap body 1, and be fixed on the conducting terminal 2 that is provided with in the cap body 1, conducting terminal 2 is by L shaped contact chip 3, and it is one-body molded and be arranged on the terminal panel 4 of L shaped contact chip 3 another sides 31 with L shaped contact chip 3, two splayed mitre joint contacts 5 that also have the edge of offering breach 41 from terminal panel 4 centers to extend internally out respectively, described L shaped contact chip 3 and terminal panel 4 perpendicular top boards 32 prevent the anti-drop device 7 that electric wire 6 comes off after being provided with and will electric wire 6 inserting, anti-drop device 7 is included in and offers on the top board 32 and electric wire 6 little big corresponding inclination strip shape gobs 8, and the spur 9 that on the end of inclination strip shape gob 8 lower plywoods 10, is provided with, described spur 9 has realized penetrating electric wire 6 and block the anticreep effect of electric wire 6 when transfering to from inclination strip shape gob 8.

Claims
