Description

The connector that is used for fluorescent lamp

Technical field

The present invention relates to a kind of connector that is used for fluorescent lamp, this fluorescent lamp for example can be belt fluorescent lamp or the compact fluorescent lamp that has with the single pedestal of four pins.

Background technology

The traditional connector that is used to have with the fluorescent lamp of the single pedestal of four pins is described with reference to figure 11A and Figure 11 B.Figure 11 A is the front view of traditional connector 5, and Figure 11 B is the A-A profile of the traditional connector 5 shown in Figure 11 A.This connector is used to connect the control circuit of light-emitting device and the pin of fluorescent tube.Owing to this not clamping of connector fluorescent tube, do not use the term of " tube clamping device " in this manual.

Two couples of contact terminal (contact terminal) 51 are symmetricly set on the connector body 50 of connector 5 about x wire L1.This contact terminal 51 is embedded into respectively in four jacks 55 of connector body 50, and four pins of fluorescent lamp pedestal are inserted into wherein.Each contact terminal 51 has two movable parts 52 and is formed on a stationary part 53 between two movable parts 52.This movable part 52 has elasticity, thereby can be out of shape when its outer surface with the pin of fluorescent lamp pedestal contacts.From the outer surface of stationary part 53 is protruding an auxiliary section 54 arranged, so that cooperate with the hook 56 of inner surface of jack 55 on the connector body 50 that is formed on connector 5.As can be seen from Figure 11A, be arranged on the stationary part 53 of contact terminal 51 of x wire L1 top respectively towards the stationary part 53 of the contact terminal 51 that is arranged on this x wire L1 below.

Figure 12 shows another traditional connector 5 ' that is used for fluorescent lamp.As shown in figure 12, it is relative with the stationary part 53 of the contact terminal 51 that is arranged on this vertical line L2 right side respectively to be arranged on the stationary part 53 of contact terminal 51 in vertical line L2 left side.

In the IEC standard, two cover gauges (gauge) have been prepared for being used to have with the connector of the fluorescent lamp of the single pedestal of four pins.Figure 13 schematically shows the position of the pin of broad gauge G1 and narrower gauge G2.In Figure 13, four circles of symbol G1 representative show the position of the pin of this broad gauge G1, and wherein the wideest spacing of the actual fluorescent lamp of the permission of the gap ratio IEC standard between the pin is wide.Show the position of the pin of narrower gauge G2 by other four rings of symbol G2 representative, wherein the narrowest spacing of the actual fluorescent lamp that allows of the gap ratio IEC standard between the pin is narrow.In other words, the pin of this gauge passes the position that the pin of actual fluorescent lamp passes never.Yet broad gauge G1 and narrower gauge G2 must can be inserted in the jack of connector, and cooperate with contact terminal, satisfy the demand of IEC standard.

Figure 14 and Figure 15 show the example of substandard products, and wherein the pin of gauge G1 and G2 can not be inserted in the jack 55, and can not cooperate with contact terminal 51.In Figure 14, the circle of symbol G1 representative shows the imaginary positions of the pin of broad gauge G1, and the circle of symbol G2 representative shows the imaginary positions of the pin of narrower gauge G2.Because movable part 52 can be out of shape along the direction that the arrow of Figure 14 is represented, the pin of broad gauge G1 can be inserted in the jack 55 of this connector body 50, and cooperates with the contact terminal 51 of connector 5.Perhaps, because stationary part 53 can not be along any direction distortion, the pin of this narrower gauge G2 can not be inserted in the jack 55 of connector body 50, can not cooperate with the contact terminal 51 of connector 5.Similarly, in Figure 15, the pin of this narrower gauge G2 can be inserted in the jack 55 of connector body 50 ', and can cooperate with this contact terminal 51, but the pin of this broad gauge G1 can not be inserted in the jack 55 of this connector body 50 ', and can not cooperate with the contact terminal 51 of this connector 5 '.

According to the international standard such as IEC, the pin of this gauge G1 and G2 must be inserted in this jack 55, and cooperates in contact terminal 51.Like this, be necessary to enlarge this contact terminal 51 along direction perpendicular to stationary part 53, make the pin of this gauge G1 and G2 can be inserted in the jack 55 of connector body 50 or 50 ', and can with the connector 5 shown in Figure 11 A, or the contact terminal 51 of the connector 5 ' shown in Figure 12 cooperates.When connector has when being provided with the similar contact terminal shown in Figure 11 A (or Figure 14), the thickness such as the insulating material of resin of the connector body between the stationary part of two relative contact terminals becomes thinner.This is difficult to the mechanical strength of the connector body of maintenance connector.Perhaps, when connector has and the similar contact terminal shown in Figure 12 (or Figure 15) when being provided with, become bigger along the connector size of the relative direction of two stationary part of this contact terminal.

In order to solve the problem of above-mentioned connector, the someone advises by a plurality of these contact terminals of element clamping.Yet owing to increased element and manufacture process, the cost of connector also can rise.

The patent application 2003-243115 of Japanese patent gazette shows another traditional connector, wherein at least one jack on the connector body of this connector does more, to allow since the pin that the thermal expansion of the thermal contraction of this connector body or this contact terminal causes with respect to the motion of contact terminal or jack.This traditional connector responds the variation of the pin spacing of fluorescent lamp.Yet its shortcoming is because the stationary part of contact terminal must be positioned at bottom apart from jack than nearer apart from movable part, thereby the length of connector can be elongated.

Summary of the invention

Below with reference to accompanying drawing describe according to the embodiment of the invention, be used to have connector with the fluorescent lamp of the pedestal of four pins.Figure 1A shows the front view of the connector 1 that is used for fluorescent lamp in the present embodiment.Figure 1B shows the C-C profile among Figure 1A.Fig. 2 A shows front view, end view and the rearview of connector 1 respectively to Fig. 2 C.Fig. 3 shows the stereogram of connector 1.Fig. 4 shows the three-dimensional exploded view of connector 1 and gauge G1 and G2.Fig. 5 and Fig. 6 show the detailed structure of contact terminal 10.

By accompanying drawing as can be seen, connector 1 is configured to four contact terminals 10 and is inserted into respectively in the jack 12 of connector body 11.

Each contact terminal 10 comprises: a pair of have a movable part 13 that enough elasticity is used as leaf spring, and this movable part 13 is integrally formed and be arranged on the stationary part 14 between movable part and be formed on auxiliary section 15 on this stationary part 14.

This stationary part 14 is flat elongated metallic plates, and this movable part 13 is formed on the both sides of stationary part 14.Movable part 13 forms respectively in the plane perpendicular to the direction of insertion of the pin of fluorescent lamp has arc section.Movable part 13 is connected with this stationary part 14 respectively near the portion in its back-end, and separates with this stationary part 14 near its leading section.Like this, when the pin of the pin of fluorescent lamp or gauge contacted with movable part, movable part 13 can be out of shape.

In addition, except near the front end, the diameter of the arc section of each movable part 13 diminishes gradually along the direction towards front end, thereby forms contact pressure with pin.Near the front end of movable part 13, the diameter of arc section becomes greatly gradually towards the direction of front end, thereby can be used as the insertion that guide portion is come guide pin.

Auxiliary section 15 is by cutting stationary part 14 and to protrude from stationary part 14 outer surfaces and to form towards the part of the crooked stationary part 14 of mode of stationary part 14 rear ends.The wire ferrule (wire cramp) 17 that is used for clamping wire 16 be formed on stationary part 14 rear ends near.Can use connector or by the welding and so on method lead 16 is connected on the stationary part 14.

By Figure 1A as can be seen, the center P of the jack 12 of connector body 11 is positioned on the summit of rectangle.In addition, jack 12 is so that the stationary part 14 of contact terminal 10 is parallel to the mode orientation that the bisector of the drift angle of the rectangle that forms by the center P that connects jack 12 is provided with.

Shown in Figure 1B, the jack 12 of connector body has an open front 18 that the pin of fluorescent lamp or gauge can pass and a rear aperture 21 that is used to install contact terminal 10.The contact terminal insertion section 19 that contact terminal 10 wherein is installed is formed on the below of open front 18 by a round flange 18a.One hook 20 is formed on the inner surface of the contact terminal insertion section 19 in the jack 12, and the auxiliary section 15 of contact terminal 10 cooperates with this hook.This hook 20 has trapezoidal shape, makes this trapezoidal hypotenuse 20a be positioned at end thereafter.When contact terminal 10 was installed in the contact terminal insertion section 19 of this jack 12 by this rear aperture 21, this auxiliary section 15 was by contacting and strain with the hypotenuse 20a of this hook 20, thereby crossed this hook 20.When this hook 20 was crossed in auxiliary section 15, it returned to reset condition owing to elasticity.Like this, the leading section of stationary part 14 cooperates with flange 18a, and auxiliary section 15 cooperates with this hook 20, thereby this contact terminal 10 immovably is installed in the contact terminal insertion section 19 of jack 12.The position of hook 20 forms respectively by this way, makes the surface of stationary part 14 have the angles of 45 degree with respect to the limit of the rectangle that is formed by the center point P that connects jack 12, and this auxiliary section 15 is from these stationary part 14 protrusions.In other words, the inner surface of the stationary part 14 of contact terminal 10 and outer surface are oriented the bisector of the drift angle that is parallel to this rectangle.Especially, shown in Figure 1A, preferably this hook 20 is positioned at the long limit of approaching the rectangle that formed by the center P that connects this jack 12.Structure thus, the distance between two auxiliary sections 15 respect to one another can be enough big, with the insulation distance and the mechanical strength of the insulating material of keeping this connector body 11.

In addition, it is parallel with the bisector that miter angle passes to be formed on the limit that this auxiliary section 15 on the stationary part 14 of contact terminal 10 further is set to with respect to rectangle.When the pedestal of fluorescent lamp when rotate with respect to connector 1 at the center of this rectangle, the side of two pins of this fluorescent lamp will contact with the stationary part 14 of these two contact terminals 10.The rotatory force of rotating the pedestal of this fluorescent lamp is received by the auxiliary section on the stationary part 14 of this contact terminal 10 15.Like this, can prevent the distortion of the movable part 13 of contact terminal 10.

At this, the variation of position of supposing the actual pin of fluorescent lamp is included in the zone that is limited by two connector gauges that are used to the fluorescent lamp of four pins, and this gauge limits according to IEC (International Electrotechnical Commission) international standard.For example, model is that this connector gauge of G10q is defined in IEC60061-3, and among the 7006-79A, model is that gauge G10q, that be used for the pin of fluorescent lamp pedestal is defined in IEC60061-3, among the 7006-79.

In Fig. 7, the circle of label 25 representatives shows the variable domain of the actual pin position of the fluorescent lamp that meets the IEC standard.The circle of symbol G1 and G2 representative shows the above-mentioned broad gauge G1 that defines in the IEC standard and the pin position of narrower gauge G2.The center of these circles 25, G1 and G2 is arranged in and is parallel to the straight line that passes the limit of this rectangle with miter angle.

As mentioned above, this circle G1 shows the position of the pin of broad gauge G1, and wherein the distance between the pin is wideer than the wideest pin spacing of the actual fluorescent lamp of IEC standard permission.Similarly, circle G2 shows the position of the pin of narrower gauge G2, and wherein the distance between the pin is narrower than the narrowest pin spacing of the actual fluorescent lamp of IEC standard permission.Like this, in theory, round G1 that protrudes from circle 25 and the part of G2 are the zones that actual fluorescent lamp pin can not pass through.

In this embodiment, consider to be used for the virtual gage of connector, it comprises the variation of position of the actual pin of the fluorescent lamp that meets the IEC standard.Be used for the position of circle 25 of virtual gage of connector and diameter corresponding to position and diameter by the hole of the gauge of the pedestal IEC standard definition, that be used for fluorescent lamp.Label 26 has been represented the center of four pins of the virtual gage that is used for connector, and it is corresponding to actual gauge that is used for connector and the center that is used for the actual gauge of fluorescent lamp pedestal.

Be oriented the bisector of the drift angle that is parallel to this rectangle respectively by the surface that is formed with stationary part 14 auxiliary section 15, contact terminal 10 thereon, the surface of this stationary part 14 further is parallel to the alignment line (alignment) of round G1 and G2, as shown in Figure 7.Direction perpendicular to circle G1 and G2 alignment line does not need the zone of considering that the actual pin of fluorescent lamp will not pass through.Like this, can be so that the distance at the inner surface of stationary part 14 and the center of the circle 25 in the change in location zone that shows the actual pin of fluorescent lamp becomes short as much as possible.

Fig. 8 shows pin and the movable part 13 of contact terminal 10 and the relation between the stationary part 14 of gauge G1 and G2.In Fig. 8, by two circles of label G1 and G2 representative position corresponding to pin when gauge G1 and G2 are installed to connector 1.The movable part 13 of each contact terminal 10 can be out of shape along the direction that arrow " a " illustrates.Yet owing to cooperate with the hook 20 of jack 12 from the auxiliary section 15 that this stationary part 14 is protruded, stationary part 14 can not be out of shape.When the position of pin can be left in the basket along the tolerance perpendicular to the direction of the alignment line of this circle G1 and G2, inner surface when this surperficial relative stationary part 14 of stretching out this auxiliary section 15, be positioned at when tangentially direction contacts with the periphery of the pin of gauge G1 and G2, it is minimum that the size of connector 1 becomes.When the tolerance of the pin position of considering fluorescent lamp, the inner surface of preferred stationary part 14 is set to tangentially contact with circle 25, and it is corresponding to the jack of the gauge of the fluorescent lamp pedestal that is used for IEC60061-3,7006-79, as shown in Figure 7.

Fig. 9 shows the E-E section of Figure 1A.As shown in Figure 9, between the inner surface of the contact terminal insertion section 19 of the outer surface of the movable part 13 of contact terminal 10 and jack 12, the edge is parallel to the direction L by the bisector of the drift angle of the rectangle that is formed centrally in the connection jack 12, have the gap, thereby movable part 13 can move along direction L.In addition, contact terminal 10 itself can move in jack 12 along direction L.Like this, when the pin of gauge G1 or G2 was inserted in the jack 12, contact terminal 10 can be moved, to cooperate the pin of gauge G1 or G2.Even the elasticity deficiency of the movable part 13 of contact terminal 10 also can be by moving the elastic limit that this contact terminal 10 prevents to exceed this movable part 13.On the other hand, between the inner surface of the contact terminal insertion section 19 of the outer surface of the auxiliary section 15 of movable part 13, stationary part 14 and the contact terminal 10 of contact terminal 10 and jack 12, there is not tolerance basically along direction perpendicular to L.Like this, contact terminal 10 is just inserted securely and is remained in the contact terminal insertion section 19 of jack 12.

Figure 10 A shows a kind of improved form that is used for the connector of fluorescent lamp according to of the present invention to Figure 10 C.As can be seen from the figure, the top ends of hook 20 forms spherical convex surface.Structure thus, the contact area between auxiliary section 15 and the hook 20 has diminished.Therefore, become complicated a little a bit although be used for the mould of connector body 11, contact terminal 10 can easily move along direction L.In addition, shown in Figure 10 B because the swing of auxiliary section 15, contact terminal 10 can be smoothly along with the pin of fluorescent lamp or gauge moves.Shown in Figure 10 C, the top of hook 20 can be formed polygonal surface.
