Description

本発明は、直管形ランプを天井等に固定するソケット、及び、そのソケットを備えた照明器具に関するものである。   The present invention relates to a socket for fixing a straight tube lamp to a ceiling or the like, and a lighting fixture including the socket.

直管形ランプを固定する際に、ランプ端部の給電ピンを挿入して回転させる回転子を備えたソケットを使用することが知られている。このようなソケットは、回転子にランプの給電ピンを挿入して装着した位置から一般的には90°程度回転子を回転させた位置でクリック感を使用者に与え、ランプが固定されたことを使用者に認識させる構成となっている。また、ランプを脱着する際にもランプを固定した位置から90°程度回転子を逆回転させた位置で使用者にクリック感を与え、ランプが脱着可能になったことを使用者に認識させる構成となっている。
従来のソケットは、回転子に設けた凸部がソケット側の導電接触片の凹部に回転中に嵌ることでクリック感を出していた(例えば特許文献1参照)。

特許第4024465号公報Japanese Patent No. 4024465

しかしながら、このようなソケットの導電接触片の凹部は、板状の金具から凹部を加工するため、寸法を出し難く、また金型費が高くなる。また、回転子の凸部が導電接触片と接触するため、樹脂で形成された回転子の凸部が削れ、ランプの装着感を得難くなる場合があった。
また、凹部は凸部の幅より長いため、回転子のピン挿入部と本体のピン挿入孔が同一直線状になり難く、ランプを回転子に挿入しづらいという問題があった。
However, since the concave portion of the conductive contact piece of the socket is processed from the plate-shaped metal fitting, it is difficult to obtain a dimension and the mold cost is high. Moreover, since the convex part of the rotor is in contact with the conductive contact piece, the convex part of the rotor formed of resin may be scraped off and it may be difficult to obtain a feeling of wearing the lamp.
Further, since the concave portion is longer than the width of the convex portion, there is a problem that the pin insertion portion of the rotor and the pin insertion hole of the main body are not easily aligned, and it is difficult to insert the lamp into the rotor.

本発明は、上記のような問題を解決するためになされたものであり、直管形ランプの装着感がよく、確実に直管形ランプを取り付けることができ、且つ安価なソケット、及び、そのソケットを備えた照明器具を提供することを目的とする。   The present invention has been made in order to solve the above-described problems, has a good feeling of mounting a straight tube lamp, can securely mount the straight tube lamp, and an inexpensive socket, and its It aims at providing the lighting fixture provided with the socket.

図1に示すように、照明器具10は、器具本体11と、反射板12とを備える。照明器具10は、器具本体11の長手方向の一端側に第一ソケット70を備え、他端側に第二ソケット30を備えることで、直管LEDランプ20を装着することができる。照明器具10は、器具本体11に取り付けられた直管LEDランプ20を点灯させる点灯装置(図示せず)を備える。反射板12は、直管LEDランプ20から発せられる光を配光する機能を有する。   As shown in FIG. 1, the lighting fixture 10 includes a fixture main body 11 and a reflection plate 12.

第二口金22は一対の略L字型形状の給電ピン26を備える。給電ピン26は、図2(b)に示すように、第二口金22の凸部25から直管LEDランプ20の軸方向に延びた軸部27と、軸部27の先端から直管LEDランプの軸の外方に延びる抜け止め部28を備える。   The second base 22 includes a pair of substantially L-shaped power supply pins 26. As shown in FIG. 2B, the power supply pin 26 includes a shaft portion 27 extending in the axial direction of the straight tube LED lamp 20 from the convex portion 25 of the second base 22, and a straight tube LED lamp from the tip of the shaft portion 27. And a retaining portion 28 extending outward from the shaft.

FIG. 3A is a front perspective view, and FIG. 3B is a rear perspective view. FIG. 4 is an exploded perspective view of the second socket 30 according to the first embodiment. 5A and 5B are views of the rotor 51 according to the first embodiment, in which FIG. 5A is a perspective view and FIG. 5B is a rear view. FIG. 6 is a perspective view of the conductive contact piece 61 according to the first embodiment. The structure of the second socket 30 will be described with reference to FIGS.

第二ソケット30は、直管LEDランプ20の第二口金22を装着できるソケットである。また、第二ソケット30は、本体31とカバー41で形成された略箱体である。   The second socket 30 is a socket to which the second base 22 of the straight tube LED lamp 20 can be attached. The second socket 30 is a substantially box formed by a main body 31 and a cover 41.

本体31は、熱可塑性樹脂の絶縁材、例えば、ポリカーボネイドやポリブチレンテレフタレートなどで形成され、第二口金22と当接する面(以下、前面と定義する)に、開口部32を有し、開口部32の周縁で前面から後面へと延びるピン挿入孔33を備える。   The main body 31 is formed of a thermoplastic resin insulating material, such as polycarbonate or polybutylene terephthalate, and has an opening 32 on a surface that contacts the second base 22 (hereinafter, referred to as a front surface). A pin insertion hole 33 extending from the front surface to the rear surface at the periphery of 32 is provided.

回転子51は、熱可塑性樹脂の絶縁材、例えば、ポリカーボネイドやポリブチレンテレフタレートなどで形成される。回転子51は、開口部32より大きい略円板状の当接部52と、この当接部52から立設する円筒部53とを有している。円筒部53には、当接部52から円筒部53の長さ方向の途中まで、回転子51を円筒部53の直径を通る直線で二分するように切り欠く、直方体凹形状のピン挿入部54が形成される。   The rotor 51 is formed of a thermoplastic resin insulating material such as polycarbonate or polybutylene terephthalate. The rotor 51 has a substantially disc-shaped contact portion 52 larger than the opening portion 32 and a cylindrical portion 53 standing from the contact portion 52. The cylindrical portion 53 has a rectangular parallelepiped-shaped pin insertion portion 54 that is notched so as to bisect the rotor 51 by a straight line passing through the diameter of the cylindrical portion 53 from the contact portion 52 to the middle of the cylindrical portion 53 in the length direction. Is formed.

直方体凹形状のピン挿入部54は、回転子51の円筒を直径方向に貫通する。円筒部53の外周のピン挿入部54が貫通する周縁部54aには、一対の第1平面部55a、55a’が形成される。また、ピン挿入部54の長手方向と直交する円筒部53の外周には、第1平面部55a、55a’と直交する平面を持つ一対の第2平面部55b、55b’が形成される。   The rectangular parallelepiped pin insertion portion 54 penetrates the cylinder of the rotor 51 in the diameter direction. A pair of first flat surface portions 55a and 55a 'are formed in the peripheral edge portion 54a through which the pin insertion portion 54 on the outer periphery of the cylindrical portion 53 passes. A pair of second flat surface portions 55b and 55b 'having a plane orthogonal to the first flat surface portions 55a and 55a' are formed on the outer periphery of the cylindrical portion 53 orthogonal to the longitudinal direction of the pin insertion portion 54.

回転子51の対向する第1平面部55aと第1平面部55a’の離隔距離、及び、第2平面部55bと第2平面部55b’の離隔距離は、後述する一対の導電接触片61のピン受け部64の離隔寸法L以下に設定してある。
また、円筒部53の中心軸から、第1平面部55a、55a’、及び、第2平面部55b、55b’の円筒部53の外周における端部56a、56a’、56b、56b’までの距離は、円筒部53の外周の半径寸法Rより長い距離に設定されている。
そして、回転子51は、本体31の内部に納められ、開口部32の中心軸と同軸上に回転自在に配設される。
The separation distance between the first flat surface portion 55a and the first flat surface portion 55a ′ facing each other of the rotor 51 and the separation distance between the second flat surface portion 55b and the second flat surface portion 55b ′ are determined by a pair of conductive contact pieces 61 described later. It is set to a distance L or less of the pin receiving portion 64.
Further, the distance from the central axis of the cylindrical portion 53 to the end portions 56a, 56a ′, 56b, and 56b ′ on the outer periphery of the cylindrical portion 53 of the first flat surface portions 55a and 55a ′ and the second flat surface portions 55b and 55b ′. Is set to a distance longer than the radial dimension R of the outer periphery of the cylindrical portion 53.
The rotor 51 is housed inside the main body 31 and is rotatably arranged coaxially with the central axis of the opening 32.

導電接触片61は、導通性のある材料、例えば、りん青銅などで形成される。導電接触片61は略コの字形状をしており、一端側がピン接触面62、他端側が端子部66で形成されている。ピン接触面62は、開口するスリット63を備え、スリット63の両端部にある接続部65を介してピン受け部64と電気的に接続されている。ピン接触面62は平板状の形状であることから、寸法精度も出やすく、金型費も安い。   The conductive contact piece 61 is made of a conductive material such as phosphor bronze. The conductive contact piece 61 is substantially U-shaped, and is formed with a pin contact surface 62 on one end side and a terminal portion 66 on the other end side. The pin contact surface 62 includes a slit 63 that opens, and is electrically connected to the pin receiving portion 64 via connection portions 65 at both ends of the slit 63. Since the pin contact surface 62 has a flat plate shape, dimensional accuracy is easily obtained and the mold cost is low.

また、給電ピン26と係合するピン受け部64は平板面状となっているため、方向性がなく、左右が同じ導電接触片61を使用することも出来る。導電接触片61のスリット63は、直管LEDランプ20を回転させたときに、給電ピン26の抜け止め部28が通過する設定となっている。そして、給電ピン26の軸部27がピン受け部64に接触することで直管LEDランプ20に通電する。また、端子部66は図示しない点灯装置からの出力電線が接続され、電力が給電される。   In addition, since the pin receiving portion 64 that engages with the power supply pin 26 has a flat plate shape, there is no directionality, and it is possible to use the conductive contact piece 61 that has the same left and right. The slit 63 of the conductive contact piece 61 is set such that the retaining portion 28 of the power supply pin 26 passes when the straight tube LED lamp 20 is rotated. Then, the straight tube LED lamp 20 is energized when the shaft portion 27 of the power supply pin 26 contacts the pin receiving portion 64. The terminal portion 66 is connected to an output wire from a lighting device (not shown) and is supplied with power.

図7は、直管LEDランプ20と回転子51と導電接触片61の接続状態を示した図であり、図7(a)は、ランプ挿入位置(0°)、図7(b)は、ランプ回転直後の位置(20°)、図7(c)は、ランプを45°回転させた位置、図7(d)は、ランプ通電位置(90°)をそれぞれ示した図である。図7(a)〜(d)を用いて直管LEDランプ20が接続されるまでの状態を説明する。   FIG. 7 is a diagram showing a connection state of the straight tube LED lamp 20, the rotor 51, and the conductive contact piece 61. FIG. 7A shows a lamp insertion position (0 °), and FIG. FIG. 7C shows the position immediately after the lamp rotation (20 °), FIG. 7C shows the position where the lamp is rotated 45 °, and FIG. 7D shows the lamp energization position (90 °). A state until the straight tube LED lamp 20 is connected will be described with reference to FIGS.

図7(a)のランプ挿入位置で回転子51のピン挿入部54に直管LEDランプ20の給電ピン26が挿入されたとき、ピン挿入部54の長手方向と直交する円筒部53の外周に形成された第2平面部55b、55b’と、平板面状のピン受け部64は平行に配設されている。回転子51の第2平面部55b、55b’と導電接触片61のピン受け部64の隙間が少なければ少ないほど、回転子51のガタツキが無くなり、第二ソケット30のピン挿入孔33と回転子51のピン挿入部54が連なることで、直管LEDランプ20の給電ピン26を挿入しやすくなる。   When the power supply pin 26 of the straight tube LED lamp 20 is inserted into the pin insertion portion 54 of the rotor 51 at the lamp insertion position in FIG. 7A, the outer periphery of the cylindrical portion 53 is orthogonal to the longitudinal direction of the pin insertion portion 54. The formed second flat surface portions 55b and 55b 'and the flat plate-like pin receiving portion 64 are arranged in parallel. The smaller the gap between the second flat surface portions 55b and 55b ′ of the rotor 51 and the pin receiving portion 64 of the conductive contact piece 61, the more the backlash of the rotor 51 is eliminated, and the pin insertion hole 33 and the rotor of the second socket 30 are eliminated. By connecting the 51 pin insertion portions 54, it becomes easy to insert the power supply pins 26 of the straight tube LED lamp 20.

次に、図7(b)のように直管LEDランプ20を回転させた直後、回転子51の第2平面部55bの一方の端部56bがピン受け部64を弾性変形させながら回転するため、回転トルクが強くなる。このピン受け部64の弾性変形量が最大量に達する前に、直管LEDランプ20を回転させる力を無くすと、ピン受け部64には、弾性変形した変形分を元の直線状態に戻す力が働き、第2平面部55bの端部56bが押し戻されて回転子51が逆回転し図7(a)の状態に戻る。つまり、回転子51が中途半端な回転位置にあるときに直管LEDランプ20を保持することが無くなり、安全性に優れたソケットを得ることができる。   Next, immediately after the straight tube LED lamp 20 is rotated as shown in FIG. 7B, one end portion 56 b of the second flat surface portion 55 b of the rotor 51 rotates while elastically deforming the pin receiving portion 64. Rotational torque becomes stronger. If the force for rotating the straight tube LED lamp 20 is eliminated before the elastic deformation amount of the pin receiving portion 64 reaches the maximum amount, the pin receiving portion 64 has a force for returning the elastically deformed deformation to the original linear state. , The end portion 56b of the second flat surface portion 55b is pushed back, and the rotor 51 rotates backward to return to the state of FIG. That is, the straight tube LED lamp 20 is not held when the rotor 51 is in a halfway rotation position, and a socket with excellent safety can be obtained.

その後、図7(c)のように第2平面部55bの端部56bがピン受け部64と接触する位置を超えるところまで直管LEDランプ20が回転すると、ピン受け部64を弾性変形させる力が無くなり、回転トルクは弱くなる。また、この状態で給電ピン26の抜け止め部28は導電接触片61のスリット63に挿入されているが、給電ピン26の軸部27は、ピン受け部64と接触していないため、直管LEDランプ20に通電されることはない。   Thereafter, as shown in FIG. 7C, when the straight tube LED lamp 20 rotates to a position where the end portion 56b of the second flat surface portion 55b exceeds the position where it contacts the pin receiving portion 64, the force that elastically deforms the pin receiving portion 64. Disappears and the rotational torque becomes weaker. In this state, the retaining portion 28 of the power supply pin 26 is inserted into the slit 63 of the conductive contact piece 61, but the shaft portion 27 of the power supply pin 26 is not in contact with the pin receiving portion 64. The LED lamp 20 is not energized.

次に、図7(d)のように直管LEDランプ20を通電位置まで回転させるが、ピン挿入部54周囲の第1平面部55aの回転子51における外周上の端部56aがピン受け部64を弾性変形させながら回転するため、回転トルクが強くなる。そして、直管LEDランプ20が通電位置に回転したところで、第1平面部55a、55a’がピン受け部64と平行になり弾性変形させる力が無くなるため、適度な装着感を得ることができる。また、第1平面部55aの端部56aがピン受け部64を最大変形させる位置を超えて回転すると、ピン受け部64に弾性変形した変形分を元の直線状態に戻す力が働き、直管LEDランプ20の回転動作を補助する。   Next, as shown in FIG. 7D, the straight tube LED lamp 20 is rotated to the energized position, but the end portion 56a on the outer periphery of the rotor 51 of the first flat portion 55a around the pin insertion portion 54 is a pin receiving portion. Since 64 rotates while being elastically deformed, the rotational torque is increased. When the straight tube LED lamp 20 is rotated to the energized position, the first flat surface portions 55a and 55a 'are parallel to the pin receiving portion 64 and there is no force for elastic deformation, so that an appropriate wearing feeling can be obtained. Further, when the end portion 56a of the first flat surface portion 55a rotates beyond the position where the pin receiving portion 64 is deformed to the maximum, a force is applied to the pin receiving portion 64 to return the deformation that has been elastically deformed to the original linear state. Assists the rotating operation of the LED lamp 20.
