Detailed description of the invention
Fig. 1 (a) is the top view of the lamp socket 50 of an embodiment of the invention, and Fig. 1 (b) is the side view of this lamp socket 50.
Lamp socket 50 has plastic main body, and this main body is integrally formed by the connector connection part 58 of the bulb installation portion 54 and the insertion aerial lug for powering to lamp with wedge-shaped base that insert lamp with wedge-shaped base (not shown). Bulb installation portion 54 and connector connection part 58 have and adapt to bulb or adapt to the square tube shape profile of adapter.In bulb installation portion 54, it is plugged with hold lamp with wedge-shaped base and the contact chip 30 contacted with the wire portion of lamp with wedge-shaped base and the sheet metal 31 of clamping lamp with wedge-shaped base. This contact chip extends to connector connection part 58, also as the connection sheet contacted with aerial lug.
In lamp socket 50, the direction that connector connection part 58 is configured to along being approximately perpendicular to bulb installation portion 54 is stretched out, when observing from the side, and its overall appearance substantially L-shaped (with reference to Fig. 1 (b)). In the lamp socket 50 of this structure, rectangular relative to the installation direction of lamp with wedge-shaped base owing to the installation direction of adapter can be curved, the advantage therefore with the length of the fore-and-aft direction that can shorten lamp casing. It should be noted that connector connection part 58 and bulb installation portion 54 angulation are not limited to right angle (90 degree).
At the lateral surface of bulb installation portion 54, it is formed with the radially-protruding round flange 64 along bulb installation portion 54. This round flange 64 entirety is substantially in disk form.
At the peripheral part of round flange 64, it is formed with circular arc gap 65A, 65B that the circumferencial direction along round flange 64 extends. Utilize above-mentioned circular arc gap 65A, 65B, form arc-shaped elastic sheet 66A, 66B that the internal side diameter with round flange 64 separates. The rear surface of arc-shaped elastic sheet 66A, 66B, the i.e. surface of connector connection part side, except two ends, other parts are relatively thin, thus make arc-shaped elastic sheet possess bigger flexibility. That is, arc-shaped elastic sheet 66A, 66B are the two fixed ends formula spring structure that its two ends are supported by. By adopting such two fixed ends formula spring to construct, it is possible to make stress be scattered in the two ends of arc-shaped elastic sheet when mounting lamp holder, it is possible to alleviate stress and concentrate such that it is able to suppress crackle.
At the upper surface of arc-shaped elastic sheet 66A, 66B, namely the surface of bulb installation portion side, it is respectively formed with contact protrusion 67A, 67B. Contact protrusion 67A, 67B are preferably disposed near the central authorities of arc-shaped elastic sheet 66A, 66B.
At the lateral surface of bulb installation portion 54, upward away from the position of round flange 64, it is formed along 4 radially projecting snap-latch pieces 82～85. Snap-latch piece 82～85 with round flange 64 to side, be respectively formed with the closer to the more big inclined plane (depicting the inclined plane 83a of the snap-latch piece 83 and inclined plane 84a of snap-latch piece 84 in Fig. 1 (b)) of the distance between top and round flange 64. Snap-latch piece 82～85 is preferably configured to and is circumferentially spaced from each other 90 degree at equal intervals.
The rear end of the inclined plane of snap-latch piece 84 is formed with claw 84b, and the rear end of the inclined plane of snap-latch piece 85 is formed with claw (not shown). As described later, by making the recess being arranged at the installing hole of lamp socket engage with above-mentioned claw, limit the rotation of lamp socket 50, be fixed in installing hole.
By Fig. 1 (a) it can be seen that arc-shaped elastic sheet 66A, 66B are arranged in not overlapping with the bearing of trend of connector connection part 58 position. Its reason is because so the mould part forming arc-shaped flexure strip and the mould part forming connector connection part 58 will to be interfered.
But, only when the position not having connector connection part 58 arranges arc-shaped elastic sheet 66A, 66B, the power fixing relative to installing hole will act on lamp socket asymmetrically, and balance is poor. For this, define the bearing of trend along connector connection part 58, namely along two linear gaps 68A, 68B of the radial direction of round flange 64, thus divide and form the linear flexure strip 70 being separated with another part of another round flange.Corresponding position, the periphery with round flange 64 on the top of linear flexure strip 70, is formed with contact protrusion 71. By arranging linear flexure strip 70, it is possible to pressing lamp socket from 3 positions together with arc-shaped elastic sheet 66A, 66B, therefore bed knife symmetry acts on lamp socket. Additionally, contact protrusion 67A on each flexure strip, 67B, 71 be preferably configured to and be circumferentially spaced from each other 120 degree at equal intervals.
By preparing the mould slided along the direction that connector connection part 58 and linear flexure strip 70 extend, it is possible to when not using die cutting die, utilize mould to make L-shaped lamp socket 50 molding.
Fig. 2 is the schematic diagram of an example of lamp socket 50 and installing hole 100 thereof.
As it can be seen, installing hole 100 is substantially round in shape, but in the position corresponding with the snap-latch piece 82～85 of the lateral surface being based in bulb installation portion 54, it is respectively formed with breach 102～105. It is also formed with inclined plane 104a, the 105a corresponding with the inclined plane of the inclined plane 84a of snap-latch piece 84, snap-latch piece 85 at breach 104,105. Additionally, circumferentially slightly away from the position of breach 104,105, be also formed with the claw 84b with snap-latch piece 84, recess 124,125 that the claw of snap-latch piece 85 engages.
The following describes the method that lamp socket 50 is installed to installing hole 100. First, the bulb installation portion side of lamp socket 50 is inserted from the downside of installing hole 100. Now, the snap-latch piece 82～85 being based in bulb installation portion 54 penetrates the breach 102～105 corresponding with installing hole 100.
When by, when press against round flange 64, making lamp socket 50 rotate along the direction of the arrow A in Fig. 2. Then, the inclined plane 84a of snap-latch piece 84 slides on the inclined plane 104a of breach 104, and the inclined plane of snap-latch piece 85 is slided on the inclined plane 105a of breach 105. And, the claw 84b of snap-latch piece 84 engages with recess 124, and the claw of snap-latch piece 85 engages with recess 125. Result forms the state of the opening edge portion of the lower face side of the contact protrusion 67A on arc-shaped elastic sheet 66A, 66B and linear flexure strip 70 slightly rearward (lower section of Fig. 2) flexure, each flexure strip, 67B, 71 pressing installing holes 100. So, it is the formation of the snap-latch piece 82～85 by the lateral surface being arranged at bulb installation portion 54 and is arranged at the arc-shaped elastic sheet 66A of round flange 64,66B, linear flexure strip 70 from the state of the opening edge portion of upper and lower sandwich installing hole, thus lamp socket is fixed.
As it has been described above, after lamp socket 50 is installed on installing hole 100, during for making the breach 103～105 of snap-latch piece 82～85 traverse be from connector connection part unilateral observation, for vacating the state in gap. Once vacate such gap, will surprisingly occur that insect enters the situation in lamp casing through gap. For preventing above-mentioned situation, the round flange 64 of lamp socket 50 is provided with the shielding plate 93～95 for hiding breach. Shielding plate 93～95 direction of rotation being configured in circular arc gap 65A, 65B along lamp socket is stretched out, be positioned at circumferentially with the corresponding equidistant position of snap-latch piece 83～85 (additionally, be not provided with the shielding plate relative to snap-latch piece 82. The breach 102 making snap-latch piece 82 traverse is blocked by connector connection part 58). This distance be used for lamp socket 50 is installed on installing hole 100 and makes the distance that lamp socket 50 rotates equal. Additionally, shielding plate 93～95 is made more slightly larger than the projected area in the plane graph of corresponding snap-latch piece 83～85.Owing to breach 103～105 is completely covered by above-mentioned shielding plate 93～95, it is possible to prevent insect from entering in lamp casing through gap.
The present invention is not limited to the respective embodiments described above, and the knowledge being also based on those skilled in the art carries out the deformation such as various design alterations. Structure shown in each figure is an illustration for an example, as long as be capable of the structure of said function, so that it may suitably change, it is achieved same effect.
