Specifically, similar with the socket terminals 16a and the 17a of aforesaid first terminal strip 14, socket terminals 25a extends downwards with an angle from the leading edge of major part 24, from the middle angle of inclination increase of socket terminals 25a.The rear portion of back, middle part is with the circular shape bending, and back edge is inclined upwardly.
Standing part 26 is crooked gradually towards the below with a predetermined angular, and the preceding terminal of sweep is straight upwards, to form a hook fastener elements 26a.In other words, fixture 26a at first is bent downwardly in its place ahead, as shown in figure 10.Then, fixture 26a is bent upwards with an angle, is bent upwards the straight rising in edge of part.
One press strip (bead) 26b forms by being compressed in the standing part 26.The formation of press strip 26b makes the base portion of the standing part adjacent with major part 24 extend to the downward-sloping part of fixture 26a.Like this, will increase the rigidity of standing part 26, thereby guarantee a stable elastic force.Therefore, under the situation of standing part repeated flex, distortion and fracture have been avoided as much as possible.
A junction divides 28 left hand edges from major part 24 back to extend in the one mode downwards.28 lower limb extends towards the direction on the right side in level one power supply wiring part 29 integratedly from the coupling part.
Further extend backwards the rear end of power supply wiring part 29, so that form power supply terminals 30.The left and right edges of power supply terminals 30 is folding downwards, and Zhe Die edge docks mutually along its longitudinal centre line under the lower surface of power supply terminals like this.As a result, the power supply terminals have the pair of lamina structure, and it increases the intensity of power supply terminals.
Shown in Figure 13 to 15, one the 3rd terminal strip 31 is made up of a major part 32 that is essentially cuboid, and this major part 32 is extended at the vertical equity of the 3rd terminal strip.An one socket wiring part 33 and a standing part 34 extend side by side integratedly from the leading edge of major part 32.Socket wiring part 33 and standing part 34 are separated from each other an interval 35.
One socket terminals 33a extends backwards integratedly from the leading edge of socket wiring part 33.Socket terminals 33a is upwards crooked gradually with the hairpin form.
As shown in figure 13, socket terminals 33a extends upward with an angle from the leading edge of major part 32.Increase from the middle angle of inclination of socket terminals 33a.In the circular arc bending of the rear portion of back, middle part, its rear rim is downward-sloping.
Standing part 34 is upwards crooked gradually, so that the leading edge of standing part 34 becomes the fixture 34a of a hook-type.Originally, fixture 34a extends upward with angle the place ahead at the socket terminals.Fixture 34a is bent downwardly then, and its edge is straight to be bent downwardly.
Similar with second terminal strip 23, a press strip 34b is formed in the standing part 34 by compacting.The formation of press strip 34b makes the base portion of the standing part 34 adjacent with major part 32 extend to the acclivitous part of fixture 34a.Like this, will increase the rigidity of standing part 34, thereby guarantee a stable elastic force.Therefore, under the situation of standing part 34 alternating bendings, distortion and fracture have been avoided as much as possible.
A junction divides 36 right hand edges from major part 32 to extend upward integratedly.Zone 37 near the 3rd terminal strip leading edge of coupling part 36 extends to and essentially identical place, the residing position of the leading edge of fixture 34a forward.
Be formed on the vertical centre position in zone 37 two grooves, 38 horizontal longitudinal extensions.The part that is clipped between two grooves 38 forms irregular quadrilateral or trapezoidal shape basically towards left side projection.As will be described in greater detail below like that trapezoidal bossing forms an adjustment thin slice 39 that contact with the part of Wedge-base bulb, pushing down the side in the Wedge-base bulb both sides, thereby controls the mobile of Wedge-base bulb.
One power supply wiring part 41 is from the top edge horizontal-extending near 36 1 zones 40, the antemarginal coupling part of the 3rd terminal strip.Specifically, power supply wiring part 41 is crooked towards a left side with the right angle along the top edge in zone 40, and the wiring part 41 after the bending is basically on the horizontal plane at the vertical middle part of the 3rd terminal strip.Further extend backwards the rear end of power supply wiring part 41, to form power supply terminals 42.The two edges of power supply terminals 42 are bent downwardly, and Wan Qu edge docks mutually along its longitudinal center under the lower surface of power supply terminals like this.As a result, the power supply terminals have the pair of lamina structure, and it increases the intensity of power supply terminals to some extent.
The internal structure of bulb jack 9 will be described below.
The wall 8 that constitutes the light bulb holder 7 of bulb jack 9 comprises a upper wall 43, a lower wall 44, one left wall 45 and a right wall 46.Terminal strip standing part and groove form to such an extent that the inner surface from the aft bulkhead 3a of main part 3 along wall 43,44,45 and 46 extends forward, to maintain first terminal strip 14, second terminal strip 23 and the 3rd terminal strip 31.
Shown in Fig. 3 to 6, rib 47 and 48 is from the upper wall 43 of wall 8 and the inner surface separately of lower wall 44, and promptly the inner surface 8a of wall 8 is protruding integratedly, so that longitudinal extension.Specifically, rib 47 from upper wall 43 one day a left side the position extend downwards, and rib 48 raises up from the place at the basic center of lower wall 44.
The part upper wall 43 and the part lower wall 44 that are positioned at rib 47 and 48 right sides are gone up the mode projection of the position of lower limb front longitudinally to extend to wall 8.In other words, the thickness of the longitudinal component of last lower wall increases to some extent than the thickness of the other parts of wall.Therefore, as shown in Figure 5, the part inner surface of upper wall 43 and lower wall 44 is cut, thereby forms the breach 43a and the 44a of certain limit at the edge of the opening part of bulb jack 9.
The terminal strip standing part 49 and 50 of piece shape is formed at the place ahead of rib 47 both sides of the upper wall 43 of wall 8, so that extend to a length from the aft bulkhead 3a of main part 3, this length is 2/3rds of light bulb holder 7 longitudinal lengths approximately.Similarly, piece shape terminal strip standing part 51 and 52 is formed at the both sides of the rib 48 of lower wall 44.
Terminal strip standing part 49,50,51 and 52 and the inner surface 8a of wall 8 between form can a roughly tripartite groove.
As shown in Figure 4, one first groove 53 has: a left side from the rib 47 of the upper wall 43 of stretching wall 8 extends to the upper part 54 of left wall 45 left; One left hand edge along left wall 45 from upper part 54 extends to the vertical component 55 of lower wall 44 with down at right angles; One along lower wall 44 from vertical component 55 lower limb extends to the lower part 56 of rib 48 with the right angle; With one from the approximately middle part of vertical component 55 towards the right side horizontally extending mid portion 57.Upper part, lower part and mid portion 54,56 and 57 are parallel to each other basically.
One second groove 58 has: a rib 47 from the upper wall 43 of stretching wall 8 extends near the upper part 59 the right wall 46 to the right; One extends to the vertical component 60 at bulb jack 9 about diameter centers with down at right angles from the left hand edge of upper part 59 along the right side of rib 47; With one from the lower limb of vertical component 60 with the horizontally extending lower part 61 in right angle.
One three-flute 62 has: a right wall 46 along wall 8 extends to lower wall 44 vertical components 63 from upper wall 43; One along lower wall 44 from vertical component 63 lower limb extends to the lower part 64 in rib 48 left sides with the right angle; With a mid portion 65 that extends towards a left side from about longitudinal middle part of vertical component 63.
As shown in Figure 4, when when socket 2 is watched in the place ahead of socket 2, terminal strip standing part 49 is below the upper part 54 of groove 53, terminal strip standing part 51 below part 56 above, terminal strip standing part 50 is below groove 58 upper parts 59, and terminal strip standing part 52 is on the lower part 64 of groove 62.The structure with terminal strip 14,23 and 31 is identical basically when its place ahead is watched with 62 structures for the groove 53,58 that forms in the bulb jack 9 of light bulb holder 7.
The mid portion 65 of the mid portion 57 of groove 53, the lower part 61 of groove 58 and groove 62 is horizontally placed mutual basically identical at the vertical centre of bulb jack 9.Part mid portion 57, lower part 61 and mid portion 65 are connected in and insert mouth 66, insert mouthful 66 rear surface 3a by main part 3 and are communicated with the connector plug jack 12 of power supply connector 10.
Describe below terminal strip 14,23 with 31 with being connected of socket 2.
The power supply terminals 22,30 and 42 that also play the effect of each terminal strip 14,23 and 31 rear ends align with insertion mouth 66 separately among the aft bulkhead 3a that is formed on main part 3, aft bulkhead 3a closure the rear end of bulb jack 9 of socket 2. Terminal strip 14,23 and 31 inserts respectively first groove 53, second groove 58 and the three-flute 62 in the bulb jack 9 from the front of socket 2 to the back.
More particularly, owing to first terminal strip 14 injects in the grooves 53, then major part 15, socket wiring part 16, socket wiring part 17, power supply wiring part 21 and power supply terminals 22 inject vertical component 55, upper part 54, lower part 56, mid portion 57 respectively and insert mouth 66.
Owing to second terminal strip 23 injects grooves 58, then major part 24, coupling part 28, power supply terminals 29 and power supply terminals 30 inject upper part 59, vertical component 60, lower part 61 respectively and insert mouth 66.
Owing to the 3rd terminal strip 31 injects grooves 62, then major part 32, coupling part 36, power supply wiring part 41 and power supply terminals 42 inject lower part 64, vertical component 63, mid portion 65 respectively and insert mouth 66.
Therefore, the socket wiring part 16 of terminal strip 14 vertically is clipped between wall 8 and the terminal strip standing part 49, and socket wiring part 17 also vertically is clipped between terminal strip standing part 51 and the wall 8.So socket wiring part is retained in the bulb jack 9 securely.Similarly, the socket wiring part 25 of terminal strip 23 vertically is clipped between wall 8 and the terminal strip standing part 50, and the socket wiring part 33 of terminal strip 31 also vertically is clipped between terminal strip standing part 52 and the wall 8.So socket wiring part is retained in the bulb jack 9 securely.
As shown in Figure 2, terminal strip 14,23 and 31 tabular power supply terminals 22,30 and 42 horizontally set in line mutually.
The bulb that is referred to as two filaments of one standard has two filaments 69 and 70 as a Wedge-base bulb 67 in the glass bulb 68 of this bulb 67.
Be connected in filament 69 in glass bulb 68 and 70 lead-in wire 71 from being substantially of glass bulb 68 rear portions oblate base portion 72 rear ends stretch out.Lead-in wire 71 is divided into a right lead-in wire and a left side lead-in wire, and they respectively along the side of base portion 72 upwards and bending up and down.Thereby form power supply terminals 71a.
Forming substantially on base portion 72 and the following big side surface is the adjustment protrusion 73 and the stop protrusion 74 of wedge, makes their directed in opposite.Specifically, on a side, form two and adjust protrusion 73, adjust in same side two and form a stop protrusion 74 between the protrusion, make their mutual horizontal alignments like this.Similarly, the correspondence position at the base portion opposite side also forms these protrusions.When Wedge-base bulb 67 is installed in the bulb jack of socket 2, adjusts protrusion 73 and contact with the inner surface 8a of wall 8.As a result, bulb 67 remains on desired direction.Stop protrusion 74 engages with the fixture 26a of terminal strip 23 and the fixture 34a of terminal strip 31 respectively, in order to avoid Wedge-base bulb 67 breaks away from light bulb holder.
At last, describe being connected of Wedge-base bulb 67 and Wedge-base bulb socket 1.
Because in the bulb jack 9 of the base portion 72 socket bodies 2 of Wedge-base bulb 67, Wedge-base bulb 67 is clamped by Wedge-base bulb socket 1, be electrically connected with socket 1 simultaneously.
As previously mentioned, terminal strip 14,23 and 31 socket wiring part 16,17,25 and 33 and standing part 26 and 34 be oppositely arranged mutually in the horizontal-shift mode.Therefore, the base portion 72 of Wedge-base bulb 67 is inserted in the bulb jack 9, vertically get through the space between socket terminals 16a, 17a, 25a and 33a and fixture 26a and the 34a simultaneously.
When base portion 72 inserted in the bulb jack 9 basically fully, the front of the stop protrusion 74,74 that terminal strip 23 and 31 fixture 26a and 34a are positioned at base portion 72 was shown in Figure 17 and 18.Finally, fixture 26a and 34a engage with stop protrusion 74, thereby avoid Wedge-base bulb 67 to break away from Wedge-base bulb socket 1.Simultaneously, terminal strip 14,23 contacts with power supply terminals 71a separately with 31 socket terminals 16a, 17a, 25a and 33a.Specifically, socket terminals 16a, 17a, 25a and 33a and fixture 26a and 34a become the state of representing with solid line from the state of representing with double dot dash line in Figure 18.Simultaneously, force the base portion 72 of bulb 67 to be inserted between fixture 26a and the 34a, thereby the gap broaden between these fixtures.Especially, when fixture 26a and 34a surpassed the stop protrusion 74,74 of base portion 72, it is maximum that the gap between the fixture can become.In this case, aforesaid breach 43a that forms in upper wall 43 and lower wall 44 and 44a can avoid fixture 26a and 34a to disturb upper wall 43 and lower wall 44.
