Abstract

An improved halogen lamp seat terminal comprises a U-shaped body, wherein tail ends of two vertical arms of the body respectively extend with an insert portion, arc projections which are convex towards the body are arranged in the middle portions of the insert portions, the arc projections could be two lugs which are punched on the two sides on the middle portions of the insertion portions, and two arc projections can form a vacancy for guiding a bulb pin to insert. A rectangular groove is cut on the middle of the bottom of the body, extends to the vertical arms of the body, and enables the elasticity of the terminal to be excellent. The improved halogen lamp seat terminal can guide a halogen lamp bulb into a lamp holder, and keeps the excellent contact performance between the bulb and the lamp holder.

Description

A kind of halogen lamp socket terminal of improvement

Technical field

The utility model relates to a kind of lamp socket terminal, refers to a kind of plug-in type terminal that is used for halogen lamp holder especially.

Background technology

Based on halogen bulb is widely used recently because of it has high brightness, high colour temperature, high-luminous-efficiency and extra long life, all uses in a large number as places such as various disk array cabinets, array frame, show rooms.

The structure of existing halogen lamp socket is, comprise ceramics seat body, mica sheet flap and two Metal Contact sheets, the mica sheet flap is fixed on the end face of ceramics seat body by two rivets, it is corresponding with the wire connecting portion of two Metal Contact sheets respectively to have two jointing holes on the mica sheet flap, as two plug-in openings that Metal Contact sheets conduction contact in halogen lamp base and the lamp socket inner chamber, be fastened on respectively after two power supply lead wires that are connected with two Metal Contact sheets are drawn from the bottom of ceramics seat body respectively on two rivets bottom the ceramics seat body.Wherein, two Metal Contact sheets are the terminal that is welded on two sheet metal combinations on the external wire, or the slightly open U-shaped terminal of opening part, when these terminals are inserted in the lamp socket at based on halogen bulb, often owing to there is not the position of position limiting structure or guiding insertion terminal being inserted distortion causes lamp socket to be scrapped, perhaps bulb is inserted askewly, made its loose contact.Avoid analogue to take place, have only careful will conscientiously the insertion in the terminal or Trap shell splinter of lamp socket behind the bulb stitch aligning, so not only inconvenient, and lose time.

The utility model content

The utility model purpose is, drawback such as solve that existing halogen lamp socket middle-end is yielding, bulb is difficult for inserting and the plug feel is bad, a kind of halogen lamp socket terminal of improvement is provided, so that bulb when inserting in the lamp socket, has the terminal convenient and swift, that dial long outstanding advantage such as not yielding of slotting good hand touch and terminal life-span of pegging graft.

The utility model is improved terminal by the following technical solutions.

A kind of halogen lamp socket terminal of improvement, comprise the U-shaped body, two perpendicular arm ends of body respectively are extended with a Plug Division, this middle part, Plug Division has to the projecting inward arcuation projection of body, described arcuation projection can be, stamp out two lugs in the both sides of middle part, Plug Division, two described arcuations convex to form the room that a guiding bulb stitch inserts; Crooked in body in the middle of at least one described Plug Division, form a clamping part that is suitable for clamping.

Also cutting has a rectangular channel in centre position, described U-shaped body bottom, and this rectangular channel may extend on the perpendicular arm of body.

Compare with the terminal in the existing halogen lamp socket, the utlity model has following beneficial effect: terminal is shaped on the convenient lug that inserts, plays guiding function in the Plug Division, make the user when bulb is inserted lamp socket, as long as the bulb stitch is placed on the terminal, slightly firmly stitch just can slip in the terminal along the lug of terminal, and by the Plug Division it is clamped.The utility model also has rectangular channel in the body bottom, and this groove can make the elasticity of terminal better, and is more not yielding.

Description of drawings

Fig. 1 is the utility model stereogram;

Fig. 2 is the utility model master cutaway view;

Fig. 3 is to use Halogen lamp LED holder structure exploded view of the present utility model.

Among the figure, 1, terminal; 2, mica sheet; 3, rivet; 4, spring; 5, lead; 6, ceramic matrix; 10, body; 11,12, Plug Division; 13, rectangular channel; 111,121, lug; 112, clamping part.

Embodiment

As shown in Figure 1, the utility model terminal 1, comprise U-shaped body 10, two perpendicular arm ends of body 10 respectively are extended with a

Plug Division

11,12, this

Plug Division

11 and 12 middle parts all have to the projecting inward arcuation projection of body, and described arcuation projection is that the both sides of 11 middle parts stamp out two lugs 111 in the Plug Division, the both sides of 12 middle parts stamp out the room that 121, two described arcuations of two lugs convex to form the insertion of a guiding bulb stitch in the Plug Division.The middle part of Plug Division 11 is also crooked in body 10, and formation one is suitable for clamping the clamping part 112 of bulb stitch, makes the contact performance of terminal 1 better.

Also cutting has a rectangular channel 13 in centre position, described U-shaped body 10 bottom, and this rectangular channel 13 extends on wherein perpendicular arm of body 10, and so structural design can make terminal 1 elasticity better, also more is difficult for deforming.

When the utility model is applied to the halogen lamp socket, at first two leads 5 are welded on respectively on the body 10 of two terminals 1, insert then in the terminal base chamber corresponding on the ceramic matrix 6, be preset with the spring 4 of traverse in the described seat chamber, terminal 1 inserts the back and is compressed by spring 4,

Plug Division

11,12 driving fits of terminal 1 opening part are pushed against, after being convenient to the lamp socket stitch and inserting with its clamping.Cover mica sheet 2 then, mica sheet 2 is provided with two spliced eyes, in order to two terminals are revealed, makes things convenient for bulb to aim at and inserts.After the whole assembling, by rivet 3 that mica sheet 2 and ceramic matrix 6 is fastening, finish the assembling of halogen lamp socket.

The utility model terminal 1 11,12 is shaped on the

convenient lug

111 and 121 that inserts, plays guiding function in the Plug Division, make the user when bulb is inserted lamp socket, as long as the bulb stitch is placed on the terminal, slightly firmly stitch just can slip in the terminal 1 along the

lug

111 and 121 of terminal 1, and by

Plug Division

11 and 12 with its clamping.The utility model also has rectangular channel 13 in body 10 bottoms, and this rectangular channel 13 can make the elasticity of terminal 1 better, and is more not yielding.

Claims

1. the halogen lamp socket terminal of an improvement, comprise the U-shaped body, two perpendicular arm ends of body respectively are extended with a Plug Division, it is characterized in that, this middle part, Plug Division all has to the projecting inward arcuation projection of body, described arcuation projection can be, stamps out two lugs in the both sides of middle part, Plug Division, and two described arcuations convex to form the room that a guiding bulb stitch inserts; Crooked in body in the middle of at least one described Plug Division, form a clamping part that is suitable for clamping.
