Description

A kind of by a lamp socket and an assembly that is configured to

Technical field

The field that the present invention relates to mainly is the low-voltage lighting device, especially relates to a lamp and is connected to a mode on the luminaire.

Background technology

The device of a lamp conductive mounting in a luminaire is commonly referred to a lamp socket.The structure of such lamp socket depends on the accessory that is located at for this purpose on the lamp.In any case, two separated electric conductors must be housed in lamp socket.Usually, the lamp socket support is formed by insulator.In addition, lamp socket must comprise accessory and be installed in the lamp socket to allow lamp, and the electric conductor of lamp just contacts with the electric conductor of lamp socket like this.The used device of fixed light for example is a screw cap, and a bayonet cap and a pin base connect, with a spring or a screw lock, the Ceramic lamp base that has so-called GX5.3 substrate that for example can get usually.

US 2101277A discloses a kind of minitype lamp lamp socket.Wherein, the conductive component of lamp socket itself has constituted lamp socket and has been separated by an insulator each other, promptly except insulator, whole bodies of lamp socket all conduct electricity, and conductive mounting is on luminaire, in these two conductors, be provided with the device that is used for conducting electricity and closely fixes the conductor of the lamp that will install, a conductor of lamp socket is littler than another conductor, and be included in fully within another conductor of lamp socket, the photograph device is linked on the big conductor, the luminaire lead is within lamp socket, and electricity is connected on the conductive component of lamp socket, provides one like this with the lamp good electrical contact.

The problem that these commercially available lamp sockets exist is that lamp socket also must be contained in the luminaire, and the power supply lamp socket from luminaire is only provided the lead conduction of copper cash or a kind of other similar diameter.Can address this problem with special lamp socket, be about to lamp socket and luminaire and be made of one and become its outside part.

The advantage of the lamp socket of this uniqueness is that the power supply that they allow to supply with lamp (does not for example move in same direction, path of current in the vertical lamp), and lamp socket can be with making with the luminaire identical materials, and this can make things convenient for fine finishining to handle for example surface treatment such as painted.But there are two problems that conductive component separates of a lamp socket in this lamp socket.Actual this should be carried out in the mode of following some international standards (seeing as IEC 598).Particularly required heat resistance can have problems, because the insulator that is placed on usually between the conductive component in most cases also plays a part two parts are fixed together, insulator must have the identical coefficient of expansion with conductive component and separately comes off to prevent them in this case.This respect is also very important when luminaire is painted with powder coating (wherein need heat), and this can offset above-mentioned advantage (identical materials).

Invention is described

The present invention wraps in another conductor by a conductor with lamp socket and addresses these problems, and above-mentioned like this advantage is kept.

The invention provides a kind of by a lamp socket and an assembly that is configured to, be used for installing conductively the lamp of a low pressure halogen lamp type, this lamp is provided with two conductive pin, wherein, lamp socket comprises two conductors, these two conductors are separated by an insulator and are fixed to described support conductively, described two conductors are provided with the device that is used for conductively and firmly fixes the conductive pin of described lamp, one of them conductor is littler than another one conductor, and bigger conductor surrounded is lived less conductor, support is connected to bigger conductor, conductor in the support links to each other conductively with the described conductor of lamp socket, thereby for lamp provides the favorable conductive contact, it is characterized in that, for two conductors of lamp socket are fixed to one another, less conductor is very closely installed, and promptly is interference fitted in the insulator, and this insulator surrounds conductor and itself is very closely installed again, promptly be interference fitted in the bigger conductor, this bigger conductor surrounds insulator fully.

Advantage of the present invention is as follows:

Two conductive components are fixed together fix and/or locking member;

There is not the problem that produces with the difference of lamp socket remainder owing to the coefficient of expansion of insulator in lamp socket;

Lamp socket can be with making with the luminaire identical materials;

Lamp socket itself can constitute an outside of luminaire;

Lamp socket allows lamp vertically to be placed on the luminaire, rather than in line;

The processing of lamp socket is simple, and it has only three critical pieces, and they also are conductors;

Lamp socket can be used for such luminaire, and wherein its support itself is a conduit, can be fixed on such luminaire rotatably;

Lamp socket can make all conduits closely connect, and this is very important to low-voltage device;

Lamp socket is observed the international statutory standards of (SELV) in this field, particularly observe the regulation in zone between the relevant management conductor, and still comparable this zone of insulator is thin, because two parts of lamp socket have chamfering and do not need insulated from each other and zone realization that just provide by this insulator and chamfering.

Accompanying drawing is described

To describe low pressure (halogen) lamp that has two-tube pin substrate (as the GX5.3 type) according to one embodiment of present invention below, wherein this lamp is vertical with luminaire lays.

Fig. 1 shows the cutaway view of lamp socket and Fig. 2 shows its stereogram.Fig. 3 and Fig. 4 are that a kind of that the luminaire of the same special shape of lamp socket combines can applicable plane graph and end view.

Embodiment

This lamp socket is by two

conductors

1,2 and insulators 3 are formed, and each other fixing do not need to use any fixing and/or locking device, because conductor 2 is littler and be tightly packed in fully in the insulator 3 than another conductor 1, this insulator 3 encases conductor 2 fully and is tightly packed in fully in another conductor 1, and this conductor 1 encases insulator 3 fully.The two ends of all three parts are all in full accord in this mode, and any one does not give prominence to other two.In order to reduce size, chamfering 14 can be made in the end in the hole in the conductor 1, spacing between insulator 3 ends and conductor 1 end just equates with the thickness of insulator like this, so just can satisfy the regulation of spacing between relevant two conductors, and insulator also can be thinner than this spacing, but two

conductors

1,2 do not need to adopt the alternate manner insulation each other.

For conductive pin 5 conductions of lamp 4 are fixing, lamp socket has special device, and this device is for having the shape of a base 6 in each

conductor

1,2 of lamp socket here.With screw pin 5 is locked in pipe and inserts within 6, said apparatus is made in lamp socket 7 for this reason.The existence of lock-screw can guarantee that lamp 4 firmly also is housed in the lamp socket conductively.The length of used screw is by the thickness decision of little conductor 2, and screw necessarily can not link to each other with another conductor 1 and must enough parts be arranged to fixedly secure in little conductor 2.

Lamp socket is linked on the luminaire, and its support 8 is one of them conduit, and another conduit 9 of luminaire passes support 8 and separated with it by an insulator 10, for example has the copper cash of an insulation shell.Lamp socket is mounted to perpendicular to luminaire in this case.

Conductive component

1 and 2 at this end lamp socket is respectively equipped with the conduit 8 and 9 of an

opening

11 and 12 to be installed in luminaire respectively.Based on same reason, install 13 for this reason and in lamp socket, formed with their locks in position with for example screw.Electrical connection between little conductor 2 and the lead 9 is realized by screw 13, makes it to pass insulator 10 pinning leads 9 by rotating this screw 13.

Lamp socket is (on 13 to 8 or 13 to 9) of being realized by connection that is used to be electrically connected and locking member in the connection on the luminaire and locking.In order to guarantee that the crucial favorable conductive of this kind lighting device is connected, should make fitting tight in practice as much as possible, this also is suitable for other all connection, can guarantee firm contact like this.Certainly, the connector to other also is like this.

If lamp is placed in line with luminaire, installation opening 11,12 and its connector 13 will change the position, and the little conductor 2 of lamp socket and insulator 3 do not need to run through whole length of conductor 1, but in the middle of for example only need arriving a bit.

Make the whole dimension of lamp socket as far as possible little if desired, so little conductor 2 best off-centre are contained in the big conductor 1.Certainly, can be at shape (hexagon, squares etc.), the definite position of connector (for example use screw fastening anything), the chamfering that may exist is (at two one side of something of lamp socket, one of or two halves, or no one, or only at an end of lamp socket), big conductor contain little conductor mode (all, one outstanding another, little conductor part is included within the big conductor etc.) etc. the aspect further replace.

To extend lamp socket outside when some when the locking device 13 of lamp socket on support 8, will obtain a backstay 16, this backstay 16 can and can be locked repeatedly with finger control, and utilize this backstay 16 can temporarily remove locking, if the assembling of lamp socket on support 8 allows lamp socket just can rotate around support 8 like this.Can use a cylindrical clamp 15 based on this above-mentioned purpose, it is around being clipped in the support end and being tightly packed in the lamp socket.Be provided with a groove around its outer surface on

locking device

13 or 15, still remain in the groove because lock when lock portion is removed, therefore rotate time slot at lamp socket and also play an extra locking effect, lamp socket just can not break away from support 8 like this.

If support 8 is near preceding 1: 17 bending of lamp socket, lamp socket just can be fastening in line with support, and still have a tie point vertical with the principal direction of support 8.This shape is except having aesthetic advantages, it also guarantee when the support shape is curved downwards (for example lamp socket is positioned at and is lower than whole luminaire tie point) luminaire for example when level is used balance dangle: owing to lamp socket extends in line with support 8, luminaire can not be subjected to gravity effect sagging, adopting one not during the horizontal connector of band bending portion 17, luminaire can be sagging in that side that is connected with lamp socket.

Bend 17 also prevents together that with backstay 16 lamp socket from further gyrating (because can rupture at the lead of this situation luminaire): when backstay 16 rotated, it was run into support 8 and is blocked, and lamp socket can only rotate in less than 360 ° of scopes like this.
