〔專利文獻1〕日本專利第2589154號公報[Patent Document 1] Japanese Patent No. 2589154
以往的防水型火災感知器，導線是經由電路基板收納部的底部附近，再從填充劑的表面延伸出來，而與電路基板收納部的周壁接觸。因而，將使導線的周圍充填不良，而有防水性不佳的問題。又，以往的火災感知器，由於最初是以兩根安裝螺絲螺著於天花板的特定位置上，因此在需要微調整火災感知器的位置時，要進行其之調整甚為困難。In the conventional waterproof fire sensor, the lead wire is in contact with the peripheral wall of the circuit board accommodating portion via the vicinity of the bottom of the circuit board accommodating portion and extending from the surface of the filler. Therefore, the circumference of the wire is poorly filled, and there is a problem that water repellency is poor. Moreover, since the conventional fire sensor is initially screwed to a specific position of the ceiling by two mounting screws, it is difficult to adjust the position of the fire sensor when it is necessary to finely adjust the position of the fire sensor.
本發明之目的在於提供一種火災感知器，係於將密封材充填於防水型的火災感知器之電路基板收納部時，與電路基板連接的導線不與電路基板收納部的周壁接觸，不會產生充填不良。又，本發明提供一種火災感知器，其本體是被螺固於天花板等的直接安裝型的火災感知器中，可簡單地安裝於期望的位置。An object of the present invention is to provide a fire sensor in which a lead wire connected to a circuit board is not in contact with a peripheral wall of a circuit board housing portion when the sealing material is filled in a circuit board housing portion of a waterproof fire sensor.

And guiding the screw guide to the screw mounting hole.
本發明之火災感知器，係由於在充填密封材時，與電路基板連接的導線，藉由設置於電路基板收納部的周壁之內側的導壁，被誘導至中央，故不會使導線與周壁接觸，可防止充填不良的產生。又，本發明的火災感知器係在將暫時固定於天花板等的1根安裝螺絲的頭部插入至缺口部之後，使感知器本體滑動，使前述安裝螺絲位於螺絲安裝孔內並鎖緊。如此，將本體暫時固定於1根安裝螺絲的狀態下，微調整該感知器本體的位置，螺著並固定其他安裝螺絲。因此，可將前述火災感知器簡單地安裝於期望的位置，並且提昇作業效率。又，由於設置螺絲導引部，因此可順利地將安裝螺絲導引至安裝孔。因此，可謀求安裝作業迅速化。In the fire sensor of the present invention, when the sealing material is filled, the lead wire connected to the circuit board is guided to the center by the guide wall provided on the inner side of the peripheral wall of the circuit board housing portion, so that the lead wire and the peripheral wall are not caused. Contact can prevent the occurrence of poor filling. Further, in the fire sensor of the present invention, after the head of one mounting screw temporarily fixed to the ceiling or the like is inserted into the notch portion, the sensor body is slid, and the mounting screw is placed in the screw mounting hole and locked. In this manner, the main body is temporarily fixed to one of the mounting screws, the position of the sensor body is finely adjusted, and other mounting screws are screwed and fixed. Therefore, the aforementioned fire sensor can be simply installed at a desired position, and work efficiency can be improved. Moreover, since the screw guide portion is provided, the mounting screw can be smoothly guided to the mounting hole. Therefore, it is possible to speed up the installation work.
第1圖係本發明之實施形態的火災感知器之一例的熱感知器20之背面圖。又，第2圖係第1圖的A－A剖面圖。第3圖係表示電路基板收納部3的周壁11和導壁7的位置關係之主要部份放大圖。略有底圓筒狀之感知器本體1，係於中央設置電路基板收納部3。再者，電路基板收納部3係具有感熱部8的插通孔15和導壁7。與感知器本體1的傾斜面14之兩側相對向，設置有用來將熱感知器20安裝於天花板等的螺絲安裝孔4a、4b。感知器本體1的前面側裝設有用來保護感熱部8及集熱板9的防護具10。熱感知器20係藉以密封材6充填電路基板收納部3，而構成防水構造。Fig. 1 is a rear view of a thermal sensor 20 which is an example of a fire sensor according to an embodiment of the present invention. 2 is a cross-sectional view taken along line A-A of Fig. 1. 3 is an enlarged view of a main part showing a positional relationship between the peripheral wall 11 of the circuit board housing portion 3 and the guide wall 7. The sensor body 1 having a slightly bottomed cylindrical shape is provided with a circuit board housing portion 3 at the center. Further, the circuit board housing portion 3 has an insertion hole 15 and a guide wall 7 of the heat sensitive portion 8. The screw attachment holes 4a and 4b for attaching the thermal sensor 20 to a ceiling or the like are provided to face the both sides of the inclined surface 14 of the sensor body 1. A guard 10 for protecting the heat sensitive portion 8 and the heat collecting plate 9 is attached to the front side of the sensor body 1. The thermal sensor 20 is formed of a waterproof structure by filling the circuit board housing portion 3 with the sealing material 6.
螺絲安裝孔4a係構成略長孔形狀，另外，螺絲安裝孔4b係使略長孔形狀的一部分缺口，而設置螺絲導引部12。因而，暫時螺固在天花板的第1安裝螺絲18，係藉由螺絲導引部12，立即被誘導至第2螺絲安裝孔4b之後而螺著。又，未圖示的第2安裝螺絲，係螺著在第1螺絲安裝孔4a。藉此，可提升熱感知器20安裝於天花板的作業性。The screw attachment hole 4a is formed in a slightly elongated hole shape, and the screw attachment hole 4b is provided with a part of the slightly elongated hole shape, and the screw guide portion 12 is provided. Therefore, the first mounting screw 18 that is temporarily screwed to the ceiling is immediately guided to the second screw attachment hole 4b by the screw guide portion 12, and is screwed. Moreover, the second mounting screw (not shown) is screwed into the first screw attachment hole 4a. Thereby, the workability of the heat sensor 20 to the ceiling can be improved.
第4圖係本發明之實施形態的火災感知器之一例的熱感知器20之螺絲導引部12的主要部份擴大圖。換言之，螺絲安裝孔4b的前端部4d側，即感知器本體1的中心側之周穴壁4g形成有缺口部16。因此，該第2螺絲安裝孔4b係朝向感知器本體1的中心開口，而形成U字狀。該缺口部係形成可插入第1安裝螺絲18的頭部18a的大小。於該缺口孔16的附近設置有螺絲導引部12。前述螺絲導引部12係具備有：用來限制水平方向位置之左右方向限制構件12a；及限制垂直方向位置的上下方向限制構件12b。再者，於周穴壁4g的附近設置複數個補強突起4f。Fig. 4 is an enlarged view of a main part of a screw guide portion 12 of the thermal sensor 20 of an example of a fire sensor according to an embodiment of the present invention. In other words, the notch portion 16 is formed on the side of the front end portion 4d of the screw mounting hole 4b, that is, the peripheral wall 4g on the center side of the sensor body 1. Therefore, the second screw attachment hole 4b is opened toward the center of the sensor body 1, and is formed in a U shape. The notch portion is formed to have a size that can be inserted into the head portion 18a of the first mounting screw 18. A screw guide portion 12 is provided in the vicinity of the notch hole 16. The screw guide portion 12 is provided with a left-right direction regulating member 12a for restricting the position in the horizontal direction, and an up-and-down direction regulating member 12b for restricting the position in the vertical direction. Further, a plurality of reinforcing projections 4f are provided in the vicinity of the peripheral wall 4g.
電路基板收納部3的周壁11，係形成可收納電路基板2的程度之略方形。周壁11的高度係設定為：以密封材6的充填可完全密封安裝於電路基板2的未圖示之電子零件。與電路基板2電性連接的複數條導線5，係在經由設置於電路基板收納部3的底部13之導壁7時，被朝向中央方向誘導，在密封材6的表面高度上，不與導線5和周壁11接觸。因此，已被充填的密封材6係流入至導線5和周壁11的間隙，導線5的外周係確實地覆蓋於密封材6。因而，密封材6不會產生充填不良，熱感知器20的電路基板2不會浸水。The peripheral wall 11 of the circuit board housing portion 3 is formed in a slightly square shape to accommodate the circuit board 2. The height of the peripheral wall 11 is set such that the electronic component (not shown) attached to the circuit board 2 can be completely sealed by the filling of the sealing material 6. The plurality of wires 5 electrically connected to the circuit board 2 are induced in the center direction when passing through the guide walls 7 provided on the bottom portion 13 of the circuit board housing portion 3, and are not in contact with the wires at the surface height of the sealing member 6. 5 is in contact with the peripheral wall 11. Therefore, the sealed sealing material 6 flows into the gap between the wire 5 and the peripheral wall 11, and the outer periphery of the wire 5 is surely covered with the sealing material 6. Therefore, the sealing material 6 does not cause a filling failure, and the circuit board 2 of the thermal sensor 20 does not become immersed in water.
導壁7係構成板狀，任意配置於電路基板收納部3的底部13。導壁7的尺寸形狀係依據電路基板收納部3的導線5的位置或條數而任意設定。又，在熱感知器20中，雖然將隔壁7a設置於複數條導線5的周圍，但不設定隔壁7a亦可。此外，導壁7和隔壁7a的高度係比電路基板收納部3的周壁11低，當密封材6充填至周壁11的高度附近時，導壁7和隔壁7a係以埋設的方式設定。藉此，密封材6係不會因導壁7和隔壁7a而產生龜裂或剝離。The guide wall 7 is formed in a plate shape and is disposed at any position on the bottom portion 13 of the circuit board housing portion 3. The size and shape of the guide wall 7 are arbitrarily set in accordance with the position or the number of the wires 5 of the circuit board housing portion 3. Further, in the thermal sensor 20, the partition wall 7a is provided around the plurality of wires 5, but the partition wall 7a may not be provided. Further, the height of the guide wall 7 and the partition wall 7a is lower than the peripheral wall 11 of the circuit board accommodating portion 3, and when the sealing material 6 is filled in the vicinity of the height of the peripheral wall 11, the guide wall 7 and the partition wall 7a are set to be buried. Thereby, the sealing material 6 does not cause cracking or peeling by the guide wall 7 and the partition wall 7a.
在此，說明如上述之構成的熱感知器20之安裝步驟的一例。此外，電路基板2係搭載事先未圖式的電子零件之感熱部8等，連接有複數條導線5。Here, an example of the mounting procedure of the thermal sensor 20 configured as described above will be described. Further, the circuit board 2 is provided with a heat sensitive portion 8 or the like of an electronic component not previously described, and a plurality of wires 5 are connected.
首先，感知器本體1的電路基板收納部3放入電路基板2。此時，感熱部8和導線5係設定於電路基板收納部3的底部13側，導線5係被導壁7朝向電路基板收納部3的頂部側彎曲。此時，感熱部8係插通於設置在感知器本體1的插通孔15。電路基板2係藉由感知器本體1之未圖示的定位暫時固定之後，加以螺固。First, the circuit board housing portion 3 of the sensor body 1 is placed in the circuit board 2. At this time, the heat sensitive portion 8 and the lead wire 5 are set on the bottom portion 13 side of the circuit board housing portion 3, and the lead wire 5 is bent toward the top side of the circuit board housing portion 3 by the guide wall 7. At this time, the heat sensitive portion 8 is inserted into the insertion hole 15 provided in the sensor body 1. The circuit board 2 is temporarily fixed by the positioning of the sensor body 1 (not shown), and then screwed.
然後，於感熱部8的前端嵌設集熱板9，未圖示的鉚接部以接著劑等保護。又，將防護具10卡止固定於感知器本體1。感知器本體1和防護具10係以接著或溶著或卡止固定等加以固定亦可。Then, the heat collecting plate 9 is fitted to the front end of the heat sensitive portion 8, and the caulking portion (not shown) is protected by an adhesive or the like. Further, the guard 10 is locked and fixed to the sensor body 1. The sensor body 1 and the guard 10 may be fixed by being attached or affixed or locked.
然後，於電路基板收納部3充填密封材6。此時，密封材6的表面高度係設為電路基板收納部3的頂面以下，且，設為導壁7的頂面以上。此外，複數條導線5係藉由導壁7與周壁11相對保留間隙，由於密封材6流入至該間隙，而不會產生充填不良。以往，於密封材6的硬化中，導線5不與周壁11接觸，雖以工具等固定，但在本發明的火災感知器中不需要。又，除了熱感知器20以外，即使是火焰感知器、煙感知器等，亦可獲得相同的效果。Then, the sealing material 6 is filled in the circuit board housing portion 3. At this time, the surface height of the sealing material 6 is equal to or less than the top surface of the circuit board housing portion 3 and is equal to or larger than the top surface of the guide wall 7. Further, the plurality of wires 5 are separated from each other by the guide wall 7 and the peripheral wall 11, and since the sealing member 6 flows into the gap, no filling failure occurs. Conventionally, in the curing of the sealing material 6, the wire 5 is not in contact with the peripheral wall 11, and is fixed by a tool or the like, but is not required in the fire sensor of the present invention. Further, in addition to the thermal sensor 20, the same effect can be obtained even with a flame sensor, a smoke sensor, or the like.
然後，說明本實施形態之安裝於天花板面的手續。Next, the procedure of attaching to the ceiling surface of this embodiment will be described.
第5圖係表示本發明之實施形態的火災感知器之一例的熱感知器20的安裝步驟剖面圖。首先，於天花板25的貫通孔27附近的特定地方，暫時固定第1安裝螺絲18。此時，前述頭部18a的底面18c和天花板25之間隔，比穴周壁4g的高度高一點。Fig. 5 is a cross-sectional view showing a mounting step of the thermal sensor 20 which is an example of a fire sensor according to an embodiment of the present invention. First, the first mounting screw 18 is temporarily fixed to a specific portion in the vicinity of the through hole 27 of the ceiling 25. At this time, the interval between the bottom surface 18c of the head portion 18a and the ceiling 25 is higher than the height of the peripheral wall 4g.
壓接配設於天花板25的背面側之感知器配線29和熱感知器20之導線5，而設為一體。The sensor wiring 29 disposed on the back side of the ceiling 25 and the wires 5 of the thermal sensor 20 are crimped and integrated.
然後，以手握住該熱感知器20的感知器本體1，使第1安裝螺絲18的頭部18a接近缺口部16。此時，缺口部16可設為能夠從下方確認第1安裝螺絲18的位置之大小。然後，將該缺口部16插入至第1安裝螺絲18的頭部18a之後，將該感知器本體1引拉至正前方。Then, the sensor body 1 of the thermal sensor 20 is held by the hand so that the head portion 18a of the first mounting screw 18 approaches the notch portion 16. At this time, the notch portion 16 can be set to a position at which the position of the first mounting screw 18 can be confirmed from below. Then, after the notch portion 16 is inserted into the head portion 18a of the first mounting screw 18, the sensor body 1 is pulled straight ahead.
如此一來，第1安裝螺絲18之頭部18a的外俓，與構成大約末寬形狀的左右方向限制構件12a抵接，而限制移動方向，又，頭部18a的頂部18b與構成略凸形狀的上下方向限制構件12b抵接，而限制移動方向。As a result, the outer rim of the head portion 18a of the first mounting screw 18 abuts against the right and left direction restricting members 12a constituting the approximately wide shape to restrict the moving direction, and the top portion 18b of the head portion 18a is slightly convex. The up-and-down direction restricting member 12b abuts and restricts the moving direction.
因而，由於第1安裝螺絲18可藉由螺絲導引部12簡單地修正左右方向及上下方向的偏移，故經由缺口部16被導引至第2螺絲安裝孔4b，使其頂部18b的底面沿著周穴壁4g的扣止端面4e移動。又，與缺口部16的下端之位置對準，而設定左右方向限制構件12a的擴張角度，或上下方向限制構件12b之天花板面的傾斜角度亦可。Therefore, since the first mounting screw 18 can easily correct the offset in the left-right direction and the vertical direction by the screw guide portion 12, the second screw mounting hole 4b is guided to the second screw mounting hole 4b via the notch portion 16 to the bottom surface of the top portion 18b. It moves along the locking end face 4e of the peripheral wall 4g. Moreover, the angle of expansion of the left-right direction regulating member 12a or the inclination angle of the ceiling surface of the up-and-down direction regulating member 12b may be set in alignment with the position of the lower end of the notch portion 16.
如此一來，第2螺絲安裝孔4b的後端部4c與該第1安裝螺絲18抵接，不會過度移動。此時，感知器本體1由於成為單邊狀態，因此即使手從感知器本體1脫離也不會掉下。As a result, the rear end portion 4c of the second screw attachment hole 4b abuts against the first mounting screw 18, and does not excessively move. At this time, since the sensor body 1 is in a one-sided state, even if the hand is detached from the sensor body 1, it does not fall.
然後，因應需要，以前述第1安裝螺絲18為中心，使感知器本體1移動或旋轉，來調整熱感知器20的固定位置。然後，若決定期望的位置，則將未圖示的安裝螺絲螺著並固定在第1螺絲安裝孔4a。而後，鎖住前述第1安裝螺絲18，設為以第5圖的一點鎖線表示的狀態，而結束安裝作業。Then, if necessary, the sensor body 1 is moved or rotated about the first mounting screw 18 to adjust the fixed position of the thermal sensor 20. Then, when the desired position is determined, a mounting screw (not shown) is screwed and fixed to the first screw attachment hole 4a. Then, the first mounting screw 18 is locked, and the mounting operation is completed in a state indicated by a one-point lock line in Fig. 5 .
